[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1

[0020] like Figure 1-4 As shown, the utility model provides a technical solution: it includes a recovery chamber 1 and a crushing motor 2, the crushing motor 2 is fixedly connected to the center of the top surface of the recovery chamber 1, and the output shaft of the crushing motor 2 is fixedly connected to the drive shaft 3, and the drive shaft 3 passes through the interior of the recovery chamber 1 from the top surface of the recovery chamber 1, and a crushing knife 4 is provided on the drive shaft 3. The crushing knife 4 is arranged on the inner wall of the drive shaft 3 located in the recovery chamber 1. There are ninety-six crushing knives 4, which are divided into six groups and arranged in a circular array at the upper end of the outer wall of the drive shaft 3. Each group of crushing knives 4 has sixteen crushing knives, and the sixteen crushing knives 4 are arranged in a linear array from top to bottom along the outer wall of the drive shaft 3.

[0021] The lower end of the recovery chamber 1 is connected to a reverse material bin 5, the bottom surface of the reverse material bin 5 is provided with a screen 6, the bottom end of the drive shaft 3 is connected to a shovel plate flush with the screen 6, and the other end of the shovel plate is connected to a reverse material leaf 7, which is spiral-shaped, and the side wall of the reverse material leaf 7 conflicts with the side wall of the reverse material bin 5.

[0022] By adopting the above design, when the crushing motor 2 drives the driving shaft 3 to rotate and drives the crushing knife 4 to crush the film entering the recovery chamber 1, it can synchronously drive the shovel plate to rotate, and then drive the reverse material blade 7 to rotate, so that when the film is crushed by the crushing knife 4, if the particle size is still large, it will be blocked above it by the screen 6, and then scooped up by the synchronously rotating shovel plate, spirally rise on the top surface of the reverse material blade 7, and enter the rotation range of the crushing knife 4 again for crushing, so that the film is reciprocated and crushed, making the film crushing effect more excellent.

[0023] The rotation of the shovel plate can clean the top surface of the screen 6, thereby preventing large particles of broken objects from accumulating on the top surface of the screen 6 and affecting its filtering effect.

[0024] A cleaning scraper 8 is fixedly connected to the end of one group of crushing knives 4 . The length of the cleaning scraper 8 is equal to that of the recovery chamber 1 , and the cleaning scraper 8 contacts the inner wall of the recovery chamber 1 .

[0025] By adopting the above design, when the crushing knife 4 rotates, the cleaning scraper 8 will rotate together with the crushing knife 4. As a result, during the crushing process, if the film crushed materials are adsorbed on the inner wall of the recovery chamber 1, the cleaning scraper 8 rotating together with the crushing knife 4 will scrape them off, thereby preventing the crushed materials from remaining in the recovery chamber 1, which will cause them to be mixed with other types of film crushed materials during the next use, affecting the next recovery and reuse of the film crushed materials. Example 2

[0026] refer to Figure 1-4As another embodiment of the present invention, a feed port 9 is provided on one side of the top surface of the recovery chamber 1, a feed motor 10 is fixedly connected to one side of the feed port 9, an electric heating roller 11 is rotatably connected in the feed port 9, and the electric heating roller 11 is fixedly connected to the output shaft of the feed motor 10.

[0027] By adopting the above design, the film needs to contact the electric heating roller 11 before entering the recovery chamber 1. After contacting the electric heating roller 11, the film will be heated and softened, reducing its hardness and toughness, which is convenient for subsequent crushing processing.

[0028] There are two electric heating rollers 11 and they are symmetrically arranged in the recovery chamber 1. One end of the electric heating roller 11 passes through the other side of the feed port 9. A transmission member 12 is provided on the other end of the electric heating roller 11. The transmission member 12 includes two gears that mesh with each other. The gears are fixedly connected to the other ends of the two electric heating rollers 11 respectively.

[0029] By adopting the above design, the two electric heating rollers 11 can be driven to rotate toward each other in the feed port 9 without adding a driving source, so that when the film passes through the feed port 9, both sides of the film will contact the electric heating rollers 11, thereby heating the film from both sides and further improving its softening degree.

[0030] In addition, the lower end of the return silo 5 is connected to a collecting chamber 13 , a drawer 14 is slidably connected to the collecting chamber 13 , and a handle is provided on the front of the drawer 14 .

[0031] By adopting the above scheme, after the film particles pass through the screen 6, they will enter the collection chamber 13 and fall into the drawer 14 along the inner wall of the collection chamber 13, so as to collect the broken film particles. The collection process is in a closed state, which can prevent the film particles from flying.

[0032] Working principle:

[0033] Feeding and preheating:

[0034] The film waste is fed into the recovery mechanism from the feed port 9, and the feed motor 10 is started, driving the two electric heating rollers 11 to rotate synchronously. The electric heating rollers 11 preheat the input film waste to soften the waste and make it easier to crush. The rotation of the electric heating rollers 11 is synchronously driven by two mutually meshing gears in the transmission member 12.

[0035] Crushing process:

[0036] The crushing motor 2 is started, driving the drive shaft 3 to rotate, and the crushing blades 4 fixed on the drive shaft 3 begin to rotate to crush the preheated film waste. There are a total of ninety-six crushing blades 4, which are distributed in six groups of circular arrays on the upper end of the outer wall of the drive shaft 3. Each group of sixteen crushing blades 4 is linearly arrayed from top to bottom to ensure that the waste is crushed in all directions. A cleaning scraper 8 is fixed to the end of one group of crushing blades 4, which rotates with the crushing blades 4 to clean the residual waste on the inner wall of the recovery chamber 1.

[0037] Screening and reprocessing:

[0038] The crushed film waste falls into the return hopper 5 and is screened through the screen 6. The fine particles that meet the requirements pass through the screen 6 and enter the drawer 14 in the collection chamber 13. The larger particles that fail to pass through the screen 6 are pushed to the return leaf 7 by the shovel at the bottom end of the drive shaft 3. The return leaf 7 is spiral in shape, and its side wall collides with the side wall of the return hopper 5, pushing the larger particles back to the recovery chamber 1 for further crushing.

[0039] Collection and Cleanup:

[0040] The drawer 14 can be slid out to collect the broken film particles. A handle is provided on the front of the drawer 14 for easy gripping and pulling out. When the drawer 14 is full, the drawer 14 can be pulled out for cleaning and then pushed back into the collection chamber 13 for continued use.

[0041] It is understood that the present invention is described by way of certain embodiments, and those skilled in the art will appreciate that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. Furthermore, under the guidance of the present invention, these features and embodiments may be modified to suit specific circumstances and materials without departing from the spirit and scope of the present invention.
