[0025] The following is combined with Figure 1 -Attached Figure 5 This application is described in further detail.

[0026] The utility model embodiment discloses a polyester film waste recycling device.

[0027] Reference Figure 1 and Figure 2 A polyester film waste recycling device includes a hollow shell 1, a feed inlet 11 is provided at the top of the shell 1, a discharge port 12 is provided at the side of the shell 1, a first crushing assembly 2 and a second crushing assembly 4 are arranged inside the shell 1, and the first crushing assembly 2 is arranged at the lower part of the feed inlet 11; when the waste is put into the feed inlet 11, the first crushing assembly 2 is used to perform the first cutting of the waste, and a guide plate 3 is arranged below the first crushing assembly 2, the guide plate 3 is arranged on the shell 1 and located below the feed inlet 11, and one end of the guide plate 3 is inclined and extends to the discharge port 12. The upper surface of the guide plate 3 is a guide surface, and the guide surface is an arc surface or a plane. In the present application, the guide surface is a plane, and the guide surface can guide the first-cut waste so that the waste comes out from the discharge port 12.

[0028] The second crushing assembly 4 is located at the discharge port 12. When the waste material comes out of the discharge port 12, the second crushing assembly 4 is used to cut the waste material again. The direction in which the first crushing assembly 2 cuts the waste material intersects with the direction in which the second crushing assembly 4 cuts the waste material in the horizontal projection plane. The polyester film waste material is first cut by the first crushing assembly 2 into a long strip or belt shape, and then cut into small pieces by the second crushing assembly 4.

[0029] In this embodiment, the direction in which the first crushing assembly 2 cuts the waste is perpendicular to the direction in which the second crushing assembly 4 cuts the waste in the horizontal projection plane.

[0030] Reference Figure 1 and Figure 2 The first crushing assembly 2 includes a first driving member 21, an active rod 22, a driven rod 23, a gear 24 and a crushing disk 25. The first driving member 21 is a motor, the output shaft of which is fixedly connected to the active rod 22 and can drive the active rod 22 to rotate. There are two gears 24, which are fixedly arranged on the active rod 22 and the driven rod 23 respectively, and the two gears 24 are meshed with each other. When the active rod 22 rotates, the driven rod 23 also rotates under the drive of the gears 24. There are multiple crushing disks 25, and the multiple crushing disks 25 are evenly fixed on the active rod 22 and the driven rod 23. The cutting direction of the crushing disk 25 is parallel to the feeding direction of the feed port 11. After the polyester film waste is put into the feed port 11, the crushing disk 25 performs the first cutting of the waste.

[0031] Reference Figure 1 and Figure 2 The side of the guide plate 3 away from the discharge port 12 is rotatably connected to the housing 1, the guide plate 3 is tilted downward toward the discharge port 12, and the end of the guide plate 3 close to the discharge port 12 extends to the discharge port 12, the guide surface is used to receive and guide the first cut waste, the lower surface of the guide plate 3 as the back of the guide plate 3 and the bottom wall of the discharge port 12 are fixedly connected with an elastic member 31, the elastic member 31 is a spring, when the second crushing assembly 4 completes the cutting of the waste on the guide plate 3 and applies a downward force to the guide plate 3, the guide plate 3 can be slightly flipped downward, so that the elastic member 31 is in a state of storing force. When the second crushing assembly 4 no longer applies an external force to the guide plate 3, the elastic member 31 releases the stored force to reset the guide plate 3.

[0032] The guide plate 3 can be swung by storing and releasing force of the elastic member 31 , thereby improving the conveying efficiency of the waste on the guide plate 3 .

[0033] Reference Figure 2 and Figure 3The second crushing assembly 4 includes a second driving member 42, a cutter 41 and a reset member 43. The second driving member 42 is a motor. A rotating wheel is fixed to the output shaft of the motor. A transmission rod is connected between the rotating wheel and the top of the cutter 41. The cutter 41 is arranged above the guide plate 3. The reset member 43 can move the guide plate 3 relative to the housing 1. Under the action of the rotation and the transmission rod, the cutter 41 reciprocates vertically 12 relative to the outlet direction of the discharge port 12.

[0034] As the second driving member 42 works, the rotating wheel can drive the transmission rod, so that the transmission rod pulls or pushes the cutter 41 to reciprocate toward the guide plate 3, and the reset member 43 can force the cutter 41 to move away from the guide plate 3, which is used to assist the cutter 41. The cutter 41 has a blade on the side facing the guide plate 3, and the cutting direction of the blade of the cutter 41 is the direction in which the waste is cut. The waste that has been cut for the first time can be cut again. The strip or belt-shaped polyester film waste can be cut into small pieces.

[0035] Reference Figure 3 and Figure 4 The reset member 43 includes a reset member 431 and a guide protrusion 432. The guide protrusion 432 is fixedly connected to both sides of the cutter 41. The shell 1 is provided with a guide groove 433. The guide groove 433 is adapted to the guide protrusion 432. The guide protrusion 432 is located in the guide groove 433. The reset member 431 is a spring and is also located in the guide groove 433. The two ends of the reset member 431 are respectively fixedly connected to the side walls of the guide protrusion 432 and the guide groove 433. When the rotating wheel pushes the cutter 41, the guide protrusion 432 can move along the path of the guide groove 433. When the cutter 41 moves downward, the blade of the cutter 41 can cut the waste on the guide plate 3.

[0036] When the cutter 41 moves downward, the guide protrusion 432 presses the reset member 431 so that the reset member 431 is compressed and accumulates force. When the transmission rod pulls the cutter 41 to move upward, the reset member 431 further pushes the cutter 41 to move upward.

[0037] The reciprocating motion of the rotating wheel and the transmission rod is utilized to cut the waste material on the guide plate 3 .

[0038] The polyester film waste recycling device further comprises a filtering assembly 5 , which is located below the discharge port 12 and is used for collecting and filtering the waste cut by the cutter 41 .

[0039] Reference Figure 3-Figure 5 , filter component 5 (such as Figure 1) comprises a swing rod 51 and a filter bag 52. The swing rod 51 and the housing 1 form a rotating pair, so that the swing rod 51 can swing relative to the housing 1. The swing rod 51 is provided with a connecting rod 54, and the filter bag 52 is provided with a connecting groove 55 adapted to the connecting rod 54. The filter bag 52 and the swing rod 51 are connected and disassembled by using the connecting rod 54 and the connecting groove 55.

[0040] Reference Figure 4 and Figure 5 The swing rod 51 has a contact surface 53. When the filter assembly 5 is not driven by external force, that is, when the transmission rod no longer drives the cutter 41 to move downward, the contact surface 53 is located below the guide protrusion 432. When the transmission rod presses the cutter 41 to move the guide protrusion 432 downward, the guide protrusion 432 can abut against the contact surface 53 and push the rod to swing relative to the shell 1. When the swing rod 51 swings, the filter pocket 52 on the swing rod 51 also swings relatively. Waste can be filtered out on the filter pocket 52, so that large pieces of waste remain in the filter pocket 52, and small pieces of waste are filtered out for recycling. The waste remaining on the filter pocket 52 can be transported back to the feed inlet 11 and cut again to meet the recycling standards.

[0041] The implementation principle of the embodiment is: unqualified polyester film waste is put into the feed port 11, and the first crushing component 2 will cut the waste vertically to form long strips or strips, and then move to the second crushing component 4 at the discharge port 12 under the guidance of the guide plate 3. The second crushing component 4 can cut the long strips or strips of waste horizontally to form small pieces of waste, thereby achieving good crushing quality and high recycling efficiency.

[0042] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application; therefore, according to the technical solution of the present invention, without changing the essential spirit of the present invention, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the above specific implementation modes and the accompanying drawings are only exemplary descriptions of the technical solution of the present invention, and should not be regarded as the whole of the present invention or as a limitation or restriction on the technical solution of the present invention.
