Description

Wear-resistant mesh cloth and gluing mechanism for manufacturing the wear-resistant mesh cloth

This creation is related to mesh cloth, especially a kind of wear-resistant mesh cloth formed by coating resin such as polyurethane on the mesh cloth and curing it to mature, and a gluing mechanism for manufacturing the wear-resistant mesh cloth.

Mesh has light and breathable characteristics, and is currently widely used in a variety of footwear, clothing hats, backpacks and other products. Moreover, manufacturers will produce mesh that meets the product characteristics according to the needs of different products. Take the mesh applied to the shoe upper as an example. After the user wears the shoes for a period of time, the mesh is repeatedly pulled and rubbed against the outside due to foot movements, resulting in wear or damage to the mesh, which affects the protection and support of the shoe. The function is reduced, which affects the appearance of the shoes.

In order to solve the above-mentioned problems of insufficient strength and toughness of the mesh when it is repeatedly pulled, and the problem of abrasion caused by friction with external objects, the manufacturer will add a resin-coated mesh process after the mesh is manufactured to make the structure of the mesh change. Get stronger. The traditional methods of resin-coated mesh can be broadly divided into two types. One is to use a roller to directly roll-coat liquid colloid (such as acrylic, ethylene/vinyl acetate copolymer, etc.) on the mesh. , and the other is to pass the mesh cloth through the impregnation tank filled with liquid colloid, so that the mesh cloth is completely soaked in the colloid to fully absorb the colloid.

Although the aforementioned methods combine the liquid colloid with the mesh, and then dry the mesh and the colloid thoroughly after drying, it will cause the color change of the mesh, the reduction of color fastness, and the hardening of the mesh structure. In particular, the drying process further strengthens the aforementioned damage to the mesh, and also increases energy consumption and thus increases manufacturing costs.

In view of the above shortcomings, the main purpose of this creation is to provide a wear-resistant mesh, which can increase the strength and toughness of its overall structure, so that the wear-resistant mesh is not easy to be torn.

In order to achieve the purpose of the previous disclosure, the wear-resistant mesh provided by this creation includes a mesh substrate and a polyurethane colloid layer; the mesh substrate has a plurality of warp bundles, a plurality of weft bundles, and the warp bundles and the A plurality of nodes and a plurality of holes formed by interlacing weft bundles; the polyurethane colloid layer covers one side of the mesh base material, and covers each of the warp bundles, each of the weft bundles and each of the nodes.

With the above technical features, the wear-resistant mesh provided by this creation can not only maintain its internal structural strength and elasticity, but also use the polyurethane colloid layer covering the side of the mesh substrate to increase the wear resistance, thereby Increase the strength and toughness of the overall structure of the wear-resistant mesh, so that the wear-resistant mesh is not easy to be torn.

Preferably, the diameter of each of the holes of the mesh base is larger than the diameter of each of the warp bundles and each of the weft bundles of the mesh base. Therefore, the air permeability of the mesh substrate is better.

On the other hand, the invention provides a gluing mechanism, which is used to manufacture the above-mentioned wear-resistant mesh cloth. The gluing mechanism includes a rubber roller, a driving roller and a scraper roller; the rubber roller system Rotatable; the driving roller wheel is located on one side of the upper rubber roller and is spaced from the upper rubber roller; the scraper roller is located on the other side of the upper rubber roller and is spaced from the upper rubber roller configuration, and the scraper roller has a scraper facing one of the outer surfaces of the upper rubber roller, and the outer surface of the upper rubber roller is stored between the scraper and the outer surface of the upper rubber roller Surface-contact polyurethane colloid; wherein, the driving roller is used to drive a mesh substrate to pass between the driving roller and the upper rubber roller.

With the above technical features, the gluing mechanism provided by this creation can apply polyurethane colloid to the mesh substrate to form the aforementioned wear-resistant mesh.

Preferably, the outer surface of the upper rubber roller wheel has a plurality of dimples, which help make the polyurethane colloid adhere to the outer surface of the upper rubber roller wheel more easily, and can be in contact with the scraper to ensure adhesion The thickness of the polyurethane colloid on the outer surface of the top rubber roller is more uniform.

Preferably, the scraper roller has a body, and the scraper is formed on the outer surface of the body along the axial direction of the body, and the length of the scraper corresponds to the length of the upper rubber roller. In this way, the scraper can scrape off the polyurethane colloid adhered to the outer surface of the upper rubber roller over the entire surface, so that the overall thickness of the polyurethane colloid remains consistent.

Preferably, the mesh base material is wound on a feeding roller, and is driven by the driving roller to be conveyed between the upper rubber roller and the driving roller. In this way, when the mesh substrate is driven forward by the driving roller, the mesh substrate will maintain a specific tension, which helps to evenly coat the polyurethane colloid on the side of the mesh substrate.

The detailed steps and characteristics of the wear-resistant mesh provided by this creation and the gluing mechanism for manufacturing the wear-resistant mesh will be described in the subsequent detailed description of the implementation. However, those with ordinary knowledge in the field of this creation should be able to understand that these detailed descriptions and the specific embodiments listed for implementing this creation are only used to illustrate this creation, and are not used to limit the scope of patent applications for this creation.

In order to describe the technical features of this creation in detail, hereby give a preferred embodiment and explain it with the drawings as follows. Please refer to Fig. 1 first. The wear-resistant mesh cloth provided by a preferred embodiment of this creation is provided by a Made by the manufacturing method 1 of the wear-resistant mesh cloth, the manufacturing method 1 of the wear-resistant mesh cloth mainly includes the following steps: a) configuring a gluing mechanism, b) using the gluing mechanism to apply polyurethane colloid to the mesh cloth substrate, and c) Mesh base material after moisture curing at room temperature. Please refer to FIG. 2 and FIG. 3 at the same time, and the above-mentioned steps a) to c) will be described in detail below.

The step of a) configuring the gluing mechanism is mainly to configure a gluing mechanism 2 at the processing site to manufacture the wear-resistant mesh provided by this creation. The gluing mechanism 2 has a rotatable upper rubber roller wheel 10, a A drive roller 20 positioned at the right side of the upper rubber roller wheel 10 and spaced apart from the upper rubber roller wheel 10, and a scraper roller 30 positioned at the left side of the upper rubber roller wheel 10 and spaced apart from the upper rubber roller wheel 10. Wherein, the outer surface 11 of the upper rubber roller 10 has a plurality of dimples 12 , and the scraper roller 30 has a body 31 and a scraper 32 facing the outer surface 11 of the upper rubber roller 10 . In this embodiment, the scraper roller 30 is fixed relative to the upper rubber roller 10, the scraper 32 is formed on the outer surface of the main body 31 along the axial direction of the main body 31, and the length L1 of the scraper 32 corresponds to the length L2 of the upper rubber roller 10 . Polyurethane colloid 40 is stored between the scraper 32 and the outer surface 11 of the upper rubber roller wheel 10, and the polyurethane colloid 40 will interact with the outer surface 11 of the upper rubber roller wheel 10. touch. When in use, the scraper roller 30 and the upper rubber roller 10 can be heated in advance. The purpose is to increase the temperature of the polyurethane colloid 40 to make it a viscous liquid, so as to smoothly adhere to the outer surface 11 of the upper rubber roller 10. When the rubber roller 10 rotates counterclockwise, the polyurethane colloid 40 will adhere to the outer surface 11 of the upper rubber roller 10, and the scraper 32 of the scraper roller 30 will scrape and cover the outer surface 11 of the upper rubber roller 10 The polyurethane colloid 40, makes the thickness of the polyurethane colloid 40 adhered to the outer surface 11 of the upper rubber roller wheel 10 consistent. It should be mentioned that when the upper rubber roller wheel 10 rotates, the scraper 32 will keep a small distance from the outer surface 11 of the upper rubber roller wheel 10 or slightly contact the outer surface 11 of the upper rubber roller wheel 10, so that the polyurethane glue 40 The dimples 12 can be evenly distributed to ensure that the thickness of the polyurethane colloid 40 attached to the outer surface 11 of the upper rubber roller 10 is uniform.

The step of b) using the gluing mechanism to coat the polyurethane colloid on the mesh base material is mainly to transport a mesh base material 60 through between the rubber roller wheel 10 and the driving roller wheel 20, so that the rubber roller wheel 10 The adhered polyurethane colloid 40 is coated on one side 61 of the mesh substrate 60 . In detail, the gluing mechanism 2 has a feeding roller 50 located below the driving roller 20 and spaced corresponding to the driving roller 20 , and the feeding roller 50 winds the mesh substrate 60 to be processed. After one end of the mesh cloth substrate 60 is pulled through the gap between the upper rubber roller 10 and the driving roller 20, it is fixed on a take-up roller (not shown) adjacent to the driving roller 20. The mesh cloth substrate 60 Contacting the surface of the driving roller 20, when the driving roller 20 rotates clockwise, the driving roller 20 will drive the mesh substrate 60 wound on the feeding roller 50 to continuously pass through the upper rubber roller 10 and the driving roller 20 In between, the polyurethane colloid 40 adhered to the outer surface 11 of the rubber roller wheel 10 is coated on the side surface 61 of the mesh cloth substrate 60 .

The step of c) solidifying the coated mesh substrate 60 with moisture at room temperature is mainly to place the mesh substrate 60 coated with polyurethane colloid 40 on the side 61 in an environment with a specific temperature and humidity, The polyurethane colloid 40 is cured naturally without being dried to form a polyurethane colloid layer. detailed In other words, after the side 61 of the mesh substrate 60 is completely coated with the polyurethane colloid 40, the mesh substrate 60 is laid flat or rolled into a bundle and placed at a temperature of 10°C to 45°C and a relative humidity of In 40% to 95% of the environment, after standing for at least 18 hours (preferably for at least 24 hours), the polyurethane colloid 40 coated on the side 61 of the mesh substrate 60 is naturally matured in this environment Cured to form a polyurethane colloid layer. It should be noted that the aging of the polyurethane colloid 40 utilizes the functional groups of the colloid molecules to react with water vapor to form a bridging effect, and the lower the humidity in the reaction process, the slower the reaction. In the aforementioned normal temperature and humidity curing environment, if the temperature is lower than 10°C, the curing time of the polyurethane colloid 40 will be too long, which does not meet the production efficiency and cost; if the temperature is higher than 45°C, although it will help shorten the curing time of the polyurethane colloid 40, it is possible An additional temperature control mechanism (elevating the ambient temperature) is required, which will consume additional energy and increase costs, thereby reducing the effect of energy saving and carbon saving. Secondly, if the relative humidity is lower than 40%, the bridging reaction speed of the reactive groups inside the polyurethane colloid 40 will be slowed down, and the curing time of the polyurethane colloid 40 will be prolonged, but an additional humidity control mechanism (increasing the ambient humidity) may be required. Consuming extra energy will increase the cost, which will affect the effect of energy saving and carbon saving. If the relative humidity is higher than 95%, the curing of the polyurethane colloid 40 can be greatly shortened, but it will cause quality problems such as the mesh base material 60 being damp, resulting in In addition, drying equipment is required to dry the mesh cloth base material 60, which consumes extra energy and increases the cost.

Comprehensively consider factors such as the effect of energy saving and carbon saving, curing time (involving production efficiency and cost) and curing degree (affecting the possibility of storage and rolling, color fastness, product touch, structural strength and other product quality), The results of repeated experiments by the creators show that the mesh substrate 60 coated with polyurethane colloid 40 is placed in the aforementioned environment with a temperature of 10°C to 45°C and a relative humidity of 40% to 95% for more than 18 hours. better, and it is better to stand in an environment with a temperature of 15°C to 40°C and a relative humidity of 45% to 90% for more than 20 hours, and to stand at a temperature of 20°C to 35°C and a relative humidity of 45% To 75% of the environment in more than 24 hours is the best.

The above is the description of the steps of the manufacturing method 1 of the wear-resistant mesh cloth. After being coated by the aforementioned method, the side 61 of the mesh cloth substrate 60 will be firmly covered with a layer of cured polyurethane colloid layer. At this time, the mesh cloth substrate 60 and the polyurethane The colloidal layer forms the wear-resistant mesh provided by this creation, and the structural features of the mesh substrate 60 and the wear-resistant mesh used will be further described in detail below. The mesh substrate 60 used in this creation can be mesh made of various sizes and specifications or various weaving methods (knitting, plain weaving). Please refer to Fig. 4 to Fig. 6, the mesh cloth base material 60 of example in this embodiment has a grid structure 62 optionally, and grid structure 62 has complex warp bundle 63, multiple weft bundle 64, and both are interlaced A plurality of holes 65 and a plurality of nodes 66 are formed. Next, the surroundings of each hole 65 (as shown in FIG. 5 ) and one side of each node 66 on the side surface 61 of the mesh cloth substrate 60 are covered with a polyurethane colloid layer (as shown in FIG. 6 ). Therefore, the wear-resistant mesh provided by this creation covers each warp bundle 63, each weft bundle 64, and one side of the node 66 on the mesh substrate 60 by the polyurethane colloid layer, which helps to make the wear-resistant mesh The structure is stronger, and the wear-resistant mesh is less likely to be torn and worn out. Even if the mesh substrate 60 with larger holes 65 and better air permeability but weaker structural strength is used, since each node 66 is covered with Polyurethane colloid layer, so that the wear-resistant mesh can still increase the strength and toughness of the overall structure and maintain a considerable structural strength without being easily torn.

In summary, the wear-resistant mesh provided by this creation can maintain its internal structural strength and elasticity, and at the same time use the polyurethane colloid 40 covering the side 61 of the mesh substrate 60 to increase the wear resistance, thereby increasing The strong toughness of the overall structure of the wear-resistant mesh makes the wear-resistant mesh not easy to be torn.

The steps and constituent elements disclosed in the above embodiments of this creation are only examples and are not used to limit the scope of this case. The substitution or change of other equivalent steps or elements should also be covered by the patent application scope of this case. cover.
