Description

Technical Field

[0001] This utility model relates to the field of extrusion equipment technology, specifically a three-layer co-extrusion composite film extrusion device. Background Technology

[0002] Composite films are polymeric materials composed of two or more layers of films made of different materials, and are mainly used for packaging.

[0003] Application CN201921229554.3 discloses a three-layer co-extrusion apparatus for cast film, relating to the field of film production technology. It includes a feeding mechanism and an extrusion mechanism located below the feeding mechanism. By lowering the surface temperature of the rollers through a cooling hood, the outer layer slurry initially solidifies and solidifies due to the low temperature of the roller surface, reducing the viscosity of the outer layer slurry and thus preventing residue from adhering to the extrusion rollers during peeling, facilitating the separation of the cast film from the extrusion rollers. However, this application has a problem in practical use: because the first, second, and third dies are not limited, there is a probability of movement when they are squeezed by the first and second extrusion rollers. Consequently, the raw material inside the first, second, and third dies cannot be completely extruded, leading to a probability of blockage. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0006] A three-layer co-extrusion composite film extrusion device includes an extrusion mechanism and an anti-clogging mechanism. The extrusion mechanism includes multiple barrels, hoses connected and communicating with the barrels, a first sleeve and a second sleeve sleeve fitted over the outside of the hoses, a first limiting plate connected between the multiple first sleeves, and a second limiting plate connected between the multiple second sleeves. The anti-clogging mechanism includes two vertically symmetrical rotating shafts about the first limiting plate, a triangular rotating cylinder fitted over the outside of the rotating shafts, a rubber rod connected to the outer wall of the triangular rotating cylinder, a gear fitted over the front end of the rotating shafts, and a motor connected to the rear end of one of the rotating shafts. The multiple hoses are located between the two rubber rods, and the two gears mesh with each other.

[0007] By adopting the above technical solution, when the raw material in the barrel flows out of the hose, the motor drives the shaft connected to it to rotate. Then, under the transmission of two gears, another shaft rotates accordingly. Then, the triangular drum drives the rubber rod to rotate. When the two rubber rods are connected, they will squeeze multiple hoses, and then the raw material in the hoses will be squeezed out completely, which effectively prevents the hoses from getting blocked.

[0008] In a preferred embodiment, the present invention can be further configured such that: a support mechanism is provided on the outside of the material cylinder, the support mechanism includes a sleeve plate connected between multiple material cylinders, a support frame connected to the bottom of the sleeve plate, and the motor body is fixedly connected to the rear side of the support frame.

[0009] In a preferred embodiment, the present invention can be further configured such that: the first limiting plate is suspended above the second limiting plate, and multiple connecting rods are connected between the first limiting plate and the support frame, and between the second limiting plate and the support frame.

[0010] In a preferred embodiment, the present invention can be further configured such that both pivots movably pass through the front side of the support frame, and the rear ends of the pivots movably extend to the rear side of the support frame.

[0011] In a preferred embodiment, the present invention can be further configured such that both the front and rear ends of the triangular rotating cylinder are in contact with the inner wall of the support frame, and the gear is in contact with the front side of the support frame.

[0012] In a preferred embodiment, the present invention can be further configured such that a baffle is sleeved at the front end of the rotating shaft, and the baffle is attached to the front side of the gear.

[0013] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0014] 1. In this utility model, when the raw material in the barrel flows out of the hose, the motor drives the shaft connected to it to rotate. Then, under the transmission of two gears, another shaft rotates accordingly. Then, the triangular drum drives the rubber rod to rotate. When the two rubber rods are connected, they will squeeze multiple hoses, and then the raw material in the hoses will be squeezed out completely, which effectively prevents the hoses from getting blocked.

[0015] 2. In this utility model, the upper half of the hose is bound by the first sleeve and the first limiting plate, and the lower half is bound by the second sleeve and the second limiting plate. This allows the hose body between the first limiting plate and the second limiting plate to be arranged side by side, which helps the two rubber rods to squeeze. At the same time, its bottom shape design allows multiple raw materials to mix with each other, improving the extrusion effect. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0027] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0028] The following describes, with reference to the accompanying drawings, some embodiments of a three-layer co-extrusion composite film extrusion device provided by this utility model.

[0029] Example 1:

[0030] Combination Figure 1-4 As shown, the present invention provides a three-layer co-extrusion composite film extrusion device, including an extrusion mechanism 100 and an anti-blocking mechanism 200. The extrusion mechanism 100 includes a plurality of barrels 110, a hose 120 connected and communicating with the barrels 110, a sleeve 130 and a sleeve 140 sleeved on the outside of the hose 120, a limiting plate 150 connected between the plurality of sleeves 130, and a limiting plate 160 connected between the plurality of sleeves 140.

[0031] The anti-blocking mechanism 200 includes two vertically symmetrical rotating shafts 210 about the limiting plate 150, a triangular rotating cylinder 220 sleeved on the outside of the rotating shafts 210, a rubber rod 230 connected to the outer wall of the triangular rotating cylinder 220, a gear 240 sleeved on the front end of the rotating shafts 210, a motor 250 connected to the rear end of one of the rotating shafts 210, and multiple hoses 120 located between the two rubber rods 230. The two gears 240 mesh with each other.

[0032] Furthermore, the first limiting plate 150 is suspended above the second limiting plate 160. Multiple connecting rods 400 are connected between the first limiting plate 150 and the support 320, and between the second limiting plate 160 and the support 320. The connecting rods 400 can firmly support the first limiting plate 150 and the second limiting plate 160.

[0033] Example 2:

[0034] Combination Figure 1 and Figure 4 As shown, based on Embodiment 1, a support mechanism 300 is provided on the outside of the material cylinder 110. The support mechanism 300 includes a sleeve 310 connected between multiple material cylinders 110 and a support frame 320 connected to the bottom of the sleeve 310. The motor 250 body is fixedly connected to the rear side of the support frame 320. With the help of the sleeve 310, three material cylinders 110 can be firmly tied together. Then, with the help of the support frame 320, the sleeve 310 can be firmly lifted to ensure that the hose 120 has sufficient installation space.

[0035] Furthermore, both pivots 210 are movable through the front side of the support frame 320, and the rear end of the pivot 210 is movable to the rear side of the support frame 320. The installation design of the pivot 210 enables the pivot 210 to firmly support the triangular rotating cylinder 220.

[0036] Furthermore, both ends of the triangular rotating cylinder 220 are in contact with the inner wall of the support frame 320, and the gear 240 is in contact with the front side of the support frame 320. The layout design of the triangular rotating cylinder 220 and the gear 240 ensures that the rubber rod 230 connected to the triangular rotating cylinder 220 can scrape off the raw material inside the hose 120.

[0037] Example 3:

[0038] Combination Figure 1 As shown, in the above embodiment, a baffle 500 is sleeved on the front end of the rotating shaft 210. The baffle 500 is attached to the front side of the gear 240. The baffle 500 can limit the gear 240 and improve the smoothness of the gear 240's rotation.

[0039] The working principle and usage process of this utility model: When this device is put into actual use, when the raw material in the material cylinder 110 flows out from the bottom of the hose 120, the various raw materials are mixed together. During this process, the motor 250 drives the shaft 210 connected to it to rotate. Then, under the transmission of the two gears 240, the other shaft 210 rotates accordingly. Then, the triangular rotating cylinder 220 drives the rubber rod 230 to rotate. When the two rubber rods 230 are connected, they will squeeze multiple hoses 120. Then, the raw material in the hose 120 is squeezed out completely, which effectively prevents the hose 120 from being blocked.

[0040] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
