Description

Technical Field

[0001] The utility model relates to the field of film processing, in particular to a film waste recycling and crushing device. Background Art

[0002] Film is a thin, soft, transparent sheet made of plastic, adhesive, rubber or other materials. The film has irregular sides after calendering, and the sides of the film need to be trimmed. The trimmed waste is generally crushed and recycled.

[0003] For example, the patent with authorization announcement number CN211917405 U discloses a TPU film waste processing device, which relates to the technical field of film waste processing. It includes a frame on which a feeding assembly, a crushing assembly and a collecting assembly are provided; the feeding assembly is used to convey the film waste to the crushing assembly; the crushing assembly is located below the feeding assembly, and the crushing assembly crushes the film waste conveyed by the feeding assembly to obtain film fragments; the collecting assembly is located on one side of the crushing assembly and is connected to the crushing assembly, and the collecting assembly is used to convey and collect the film fragments produced in the crushing assembly.

[0004] In the above patent, the staff can directly obtain the collected film fragments from the collecting component, so that the utility model has the advantage of easy cleaning of the film fragments; however, the disadvantage of the above patent is that: the above patent adopts a feeding component for feeding, and the waste material enters from the active material roller and then the auxiliary material roller, but in actual production, the flatness of the film waste is relatively general, and most of the waste material is crumpled into a ball. The waste material needs to be manually flattened before it can be stuffed between the active material roller and the auxiliary material roller, which is time-consuming and labor-intensive.

[0005] Therefore, it is necessary for us to improve such a structure to overcome the above-mentioned defects. Utility Model Content

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. The components of the embodiments of the present invention generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the utility model for protection, but merely represents selected embodiments of the present invention. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0024] See also Figure 1-7 , film waste recycling and crushing device, including a bracket 1,

[0025] A crushing bin 2 is fixedly installed above the bracket 1, and a feeding bin 3 is connected to the top of the crushing bin 2;

[0026] Specifically, the support 1 includes a workbench 101 and a column 102.

[0027] Four upright posts 102 are fixedly mounted vertically downward at the four corners of the bottom of the workbench 101. A motor mounting platform 103 is also fixedly mounted on the side of the bracket 1. The bottom of the motor mounting platform 103 is fixedly connected to the adjacent upright posts 102 via two oblique supports 104.

[0028] At the same time, in this solution, a rectangular groove 105 is provided in the center of the workbench 101;

[0029] The crushing bin 2 is rectangular in shape as a whole, and is opened at the upper and lower ends of the crushing bin 2. At the same time, the bottom of the crushing bin 2 is further downwardly connected to a lower hopper 201, wherein the lower hopper 201 passes through the rectangular slot 105 on the workbench 101, and the bottom of the lower hopper 201 is closed.

[0030] Two crushing shafts 202 are horizontally arranged in the crushing bin 2, and a plurality of crushing discs 203 are evenly spaced on the crushing shafts 202. The crushing discs 203 on the two crushing shafts 202 are staggered with each other; a plurality of crushing teeth 204 are arranged in a circular array on the crushing discs 203;

[0031] Both ends of the crushing shaft 202 pass through the crushing bin 2 and are rotatably connected to the outer wall of the crushing bin 2 through bearings and bearing seats. At the same time, a gear 205 is fixedly installed on the left end of the crushing shaft 202, and the gears 205 on the two crushing shafts 202 are meshed with each other.

[0032] A reducer 206 is fixedly installed on the top of the motor mounting platform 103, and a crushing motor 207 is fixedly installed on one side of the reducer 206. The output shaft of the crushing motor 207 is connected to the reducer 206, and the output shaft of the reducer 206 is connected to one of the crushing shafts 202 through a coupling.

[0033] The crushing motor 207 drives one of the crushing shafts 202 to rotate, and this crushing shaft 202 drives the other crushing shaft 202 to rotate through the gear 205, so that the waste passing between the two crushing shafts 202 is crushed by the crushing disk 203;

[0034] The feed bin 3 is in the shape of a rectangular shell as a whole, and the lower end of the feed bin 3 is closed. The lower end of the feed bin 3 is in the shape of an inverted trapezoidal table as a whole, and the bottom of the feed bin 3 is fixedly connected to the top of the crushing bin 2;

[0035] This structure of the feed bin 3 is advantageous in that, while being adapted to the top opening of the crushing bin 2, a larger feed bin 3 and bin door 301 can be manufactured, thereby allowing for more film waste to be stuffed in, and the lower end of the feed bin 3 is closed;

[0036] The front end of the feed bin 3 is open, and the front end of the feed bin 3 is also connected to a bin door 301 by a hinge. At the same time, a handle 302 is fixedly installed on the front end of the bin door 301 to facilitate opening the bin door 3;

[0037] The feed bin 3 is further provided with an extrusion device 4, which includes an extrusion cylinder 401 and an extrusion plate 402 driven by the extrusion cylinder 401.

[0038] The extrusion cylinder 401 is fixedly mounted on the top of the feed bin 3, and the output shaft of the extrusion cylinder 401 passes through the top of the feed bin 3 and is fixedly connected to the top center of the extrusion plate 402; at the same time, in this solution, in order to standardize the up and down movement path of the extrusion plate 402, the top of the extrusion plate 402 is also vertically fixedly connected to a guide shaft 403, wherein the top of the feed bin 3 is also fixedly mounted with a linear bearing 404, and the guide shaft 403 passes through the linear bearing 404 and is slidably connected thereto;

[0039] At the same time, in this solution, since the lower end of the feed bin 3 is in the shape of an inverted trapezoid, in order to ensure that more waste is stuffed into the crushing bin 2, the four sides of the extrusion plate 402 are rotatably connected to the auxiliary plate 405 by hinges, and a limit block 406 is fixedly installed on the side of the auxiliary plate 405 close to the extrusion plate 402;

[0040] The function of the limit block 406 is to prevent the auxiliary plate 405 from turning over when the auxiliary plate 405 is squeezed by the waste material at the lower end of the feed bin 3. The auxiliary plate 405 can only turn over to the same angle as the lower end inner wall of the feed bin 3.

[0041] When the utility model is put into use, the door 301 is opened to put the film waste into the feed bin 3. At this time, since the waste is mostly crumpled, it is difficult for the waste to enter the crushing disc 203 and be crushed. At this time, the door is closed, and the extrusion cylinder 401 is actuated to push the extrusion plate 402 downward to press the waste into the crushing bin 2.

[0042] In the initial stage of the movement of the squeezing plate 402, that is, when it is above the closing position of the feed bin 3, the squeezing plate 402 and the auxiliary plate together press the waste downward; the auxiliary plate is an iron plate, which can press the film waste by its own gravity;

[0043] When the extrusion plate 402 moves to the closing position of the feed bin 3, the auxiliary plate 405 flips upward, and the extrusion plate 402 can move downward further, so that the waste can be pushed into the crushing bin 2 more thoroughly; after the waste enters the crushing bin 2, it is crushed by the crushing disc 203 and falls from the lower hopper 201.
