Description

The utility model relates to the field of conveyor stands that carry out continuous production.

A method for producing honeycomb plastic and an installation for its implementation are known (patent RU 2008227 C1, published 1994.02.28, IPC B 32 B 3/12). The invention relates to the production of lightweight cellular fillers of the honeycomb structure type, intended for use in multilayer structures as fillers, the main requirements for which are high values of specific strength (m / σ) and specific stiffness (m / E).

The disadvantages include the possibility of corrugating only sheets made of non-reinforced thermoplastic, since corrugating sheets reinforced with the listed materials using this method leads to their inevitable destruction due to the resulting tensile forces due to the difference in the expanded length of the corrugated row and the geometric width of the honeycomb plastic in the absence of slippage of the material during corrugation and the lack of plasticity due to the rigidity of the reinforcing systems.

The closest solution to the claimed one is the one described in the description of Russian Patent Application No. 320392. The known device is designed for continuous longitudinal corrugation of polymer strips and comprises forming elements in the form of rotating support and pressure rollers, movable relative to each other along the height, creating a gap for drawing the formed material. The device produces straight corrugations, and the product itself with such corrugations is intended to increase strength properties and reduce weight. Furthermore, the free arrangement of the rollers on the shafts ensures that only materials such as polymers, cardboard, and the like are drawn.

Due to its design features, the known device only produces straight corrugations, which limits its use.

The technical problem being solved is a linear corrugating stand, which is a conveyor due to technological features that allow the production of honeycomb filler on an industrial scale with a dovetail configuration.

The technical result is a technological equipment - a corrugating linear stand, consisting of a main frame and rollers for corrugating installed on it, as well as additional assembly elements used for adjustment, in turn, there is a feature of interchangeability of assembly elements (rollers), due to which it becomes possible to manufacture other honeycomb fillers.

The device is shown in the drawings.

Isometric projection of process equipment: a linear corrugating stand for the production of dovetail-shaped honeycomb filler.

On the body 1 of the process equipment there are covers 8, rollers 9, handle 2, gears 3, studs 4, extended studs 5, shafts of the rear struts 6, bolts 7, adapters 10, shaft adjustment bushings 11, support 12, regulator 13, guides 14, crossbars 15, tubes 16, cylinders 17, belt 18.

Housing 1 is a welded structure with a rectangular base frame and ten columns aligned coaxially opposite one another. Housing 1 contains openings for mounting rollers 9, which are used for corrugating paper.

Before installing the rollers, it is necessary to install the adjustment system, located on the 8 front racks of the process equipment, which consists of:

1. Cover 8, installed in the upper part of the racks and having technological holes for fixing to the body 1.

2. Regulator 13, having an opening in the base and rigidly fixed by tube 16.

3. Bolt 7, connecting regulator 8 and regulator 13.

After installation and fixation of the shaft adjustment system in the initial position, adapter 10 is attached to the protruding tubes 16 from the outer part in a staggered pattern.

A shaft adjustment sleeve 11 is installed inside the rear struts of the process equipment, which is pressed using a bolt 7. Two elongated studs 5 enter the shaft adjustment sleeve 11 along the upper and lower parts, passing through the shafts of the rear struts 6 and also exiting through the shaft adjustment sleeve 11.

Between the pillars 4 and 5 of the rows, a support 12 is installed, in the technological grooves of which a crossbar 15 is fixed with cylinders 17 already on it and guides 14 fixed to it. Also, a belt 18 is thrown over the shafts of the rear pillars 6 and the support 12

Rollers 9, located below the central axis, are secured with two pins 4 per roller, installed through openings with two tubes 16 per roller. Before installing roller 9, located at the rear of the structure, belt 18 is placed over it.

Rollers 9, located above the centerline, are installed into the process equipment using pins 4, which pass through the already installed roller adjustment system. Before installing roller 9, located at the rear of the structure, a belt is first passed over it.

The pin 4 is installed in the first row of the shaft 9, and the handle 2 and gears 3 are attached to it.

The device works as follows.

Mechanical energy is transmitted from the handle to the rollers of the first row, which are connected by a gear transmission consisting of gears mounted on pins passing through tubes located in the rollers. The gears are secured in two rows using specially designed mounting holes:

1. The first row transmits torque to the gears of the rollers located below the central axis.

2. The second row facilitates the transfer of mechanical energy from the first row of rollers to the second row using adapters.

The adapters are installed between the frame's uprights and secured to the tubes. The tubes, in turn, are firmly secured to the regulators.

The rollers of the first and second rows create a creasing pattern for the paper passing through them along the centerline of the axis, located between the upper and lower rollers. The paper then passes through the third row of rollers and assumes a rectangular shape. After a predetermined distance, it enters the rollers of the fourth row, which are connected by a closed belt that transmits torque from the roller of the fourth row to the roller of the fifth row, located above the central axis. The rollers of the fourth and fifth rows, located below the central axis, are connected by a closed belt, which also transmits torque from the roller of the fourth row to the roller of the fifth row.

Between the rollers of the fourth and fifth rows, guides are installed along the central axis line, which serve to fold the corrugated paper into a given shape.
