Abstract
The utility model discloses a longitudinal color film extrusion machine with simple structure and convenient operation. The two sides of the center wind window of the utility model are connected with air channels, the center wind window is fixed with base plate, the base plate is provided with at least two concentric feeding rings. The side standing walls of the feeding rings are equipped with feeding entrances, the center of the feeding ring is provided with a flow passage body with at least two flow passages. Each feeding entrance communicates with the lower end of the corresponding flow passage respectively. The upper end of the corresponding flow passage communicates with the corresponding flow passage groove in the mold head respectively. The mold head, from outside to inside, consists of the outside mold body, the helicoidal body corresponding to the flow passage and mold core. Each flow passage groove communicates with the film outlet groove in the mold core. The utility model can produce various multicolor combined plastic film wrapper which changes the status that the present plastic films are all with single style.
Description
Technical field
The utility model relates to the manufacturing machine apparatus field, more particularly, relates to a kind of body thin film extruder that can extrude different colours simultaneously.
Background technology
Along with the prosperity in market, the continuous increase of product category, packaging industry is also developed rapidly thereupon.Plastic sheeting becomes the main separation raw material of existing packaging material, and existing film extruder can only be produced the film of solid color, and the product of this dullness can't satisfy the demand for development of present packaging industry and consumer's aesthetic requirement.
The utility model content
Technical problem to be solved in the utility model is, overcomes the deficiencies in the prior art, and a kind of vertical colorful film extruder simple in structure, easy to use is provided.
The vertical colorful film extruder of the utility model, be achieved by following technical proposals, air regulator both sides, center connect ventilation shaft, described center air regulator is fixed with base, stack at least two concentric feeding rings on the described base, described feeding ring side elevation is provided with feeding port, and feeding ring center is provided with the runner body that contains at least two runners, described each feeding port communicates with corresponding runner lower end respectively, and described corresponding runner upper end communicates with corresponding flow path groove in the die head respectively; Described die head be from outside to inside outer die body, with corresponding conveyor screw of runner and core rod, described each flow path groove all communicates with the core rod film outlet groove.
Each conveyor screw described in the utility model is for going in ring, and the center of circle is identical, the radius difference.The quantity of described feeding port, runner and flow path groove is identical.The quantity of described feeding port or runner or flow path groove is 2～9.
The utility model is sent into the polymer of different colours respectively by different feeding ports, the polymer melt of different colours is filled the runner (wherein at least one belt runner is incomplete circumference) that goes in ring separately, the polymer melt of different colours is pooled to die head through different separately runners lip becomes film through extrusion-blown modling or curtain coating, can realize different with integral color or the whole colorful film that vertically constitutes for multiple color of local color.The utility model can be produced the plastic film packaging material of multiple many color combination, changes the single present situation of plastic sheeting existing product.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, air regulator 13 both sides in center connect ventilation shaft, the ventilation shaft middle part is provided with two air channels negative pressure vane distributor chamber 16, ventilation shaft top is provided with two air channels negative pressure vane 14, one side of center air regulator 13 is fixed with base 20, stacks at least two concentric feeding rings on the base, and present embodiment is an example with three, be outer feeding ring 17, middle level feeding ring 18, internal layer feeding ring 19, each feeding ring side elevation is respectively arranged with feeding port; Feeding ring center is provided with the runner body 21 that contains at least two runners, and present embodiment is three runners, and each feeding port communicates with corresponding runner lower end respectively, and corresponding runner upper end communicates with corresponding flow path groove in the die head respectively; Die head be from outside to inside outer die body 8, with corresponding conveyor screw of runner and core rod 1, the feeding port of promptly outer feeding ring 17 is communicated with outer flow passage lower end in the runner body 21, the upper end of outer flow passage is connected with the flow path groove of outer die body 8 with outer conveyor screw 7 formation; The feeding port of middle level feeding ring 18 is communicated with middle runner lower end in the runner body 21, and the upper end of middle runner is connected with the flow path groove that outer conveyor screw 7 forms with middle level conveyor screw 6; The feeding port of internal layer feeding ring 19 is communicated with inner flow passage lower end in the runner body 21, and the upper end of inner flow passage is connected with the flow path groove that middle level conveyor screw 6 forms with internal layer conveyor screw 5; Each flow path groove all communicates with the core rod film outlet groove; In internal layer flow path groove inboard inner filtration body 2 is set, the outer filtering bodies 4 of layer flow path groove arranged outside outside, runner body 21 shells are provided with rotation with bearing 10 and 11, adjust rotation with bearings 10 and 11 by rotation with machine governor 12.If produce colorful film, swivel bearing be set in process of production do not rotate.
With three-layer co-extruded, extrude whole film product and be hyaline membrane for part, part is that example illustrates operation principle of the present utility model for the magnetic tunica albuginea: outer feeding ring feeding port is dosed the LDPE resin, middle level feeding ring feeding port is dosed LDPE resin and the white master batch of magnetic, internal layer feeding ring feeding port is dosed the LDPE resin, then according to the gap between product needed adjusting middle level conveyor screw and the outer conveyor screw, be that the flow path groove cross section that middle level conveyor screw and outer conveyor screw form is the part circumference, then have only part can extrude the white films of adding the white master batch of magnetic, the whole film of extruding by the film outlet groove of core rod is part and is hyaline membrane, part is the magnetic tunica albuginea.
Can be multi-layer co-extruded structure according to concrete needs the utility model, every layer is provided with different colours and regulates gap between each helical layer body, thereby obtains containing the whole film of different colours.
