Description

Technical Field

[0001] This utility model relates to the field of waste removal technology for PVC medicine packaging materials, and more specifically, to a waste removal device for the production of PVC medicine packaging materials. Background Technology

[0002] In the pharmaceutical packaging industry, PVC materials are widely used in the production of pharmaceutical packaging products such as rigid pharmaceutical sheets, aluminum-plastic blister packs, and the outer layer of infusion bags due to their excellent barrier properties, chemical resistance, and molding stability. During the cutting, stamping, and molding processes of PVC pharmaceutical packaging materials, a large amount of waste, including scraps, defective products, and roll material residues, is generated. Directly discarding this waste not only wastes resources but may also pollute the environment due to residual trace amounts of pharmaceutical ingredients or printing ink.

[0003] Traditional waste removal devices often use fixed metal screens for screening, relying solely on the material's own gravity to complete the screening. However, since PVC pharmaceutical packaging waste is finely crushed and the residual printing ink and composite adhesive layer on the surface are slightly sticky, the material easily adheres to the screen surface during the fall, or accumulates at the screen holes, forming small particles that stick together and block the screen holes. Once blockage occurs, the machine must be stopped and the screen manually cleaned, which not only interrupts the production process but also affects the continuity of production. Therefore, a waste removal device for the production of PVC pharmaceutical packaging materials has been designed. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a waste removal device for the production of PVC medicine packaging materials, which has the advantage of improving waste removal efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a waste removal device for the production of PVC pharmaceutical packaging materials, comprising a waste removal platform, a crushing frame fixedly connected to the top of the waste removal platform, a main crushing shaft rotatably connected to the inner wall of the crushing frame, a crushing blade fixedly connected to the outer wall of the main crushing shaft, two drive wheels symmetrically fixedly connected to the end of the main crushing shaft away from the crushing blade, two hinge seats symmetrically fixedly connected to the bottom of the waste removal platform, a vibrating frame hinged to the inner wall of the two hinge seats, a screen slidably connected to the inner wall of the vibrating frame, two push wheels symmetrically fixedly connected to the top of the screen, two bearing blocks symmetrically fixedly connected to the lower surface of the waste removal platform, a connecting shaft rotatably connected to the inner wall of the bearing blocks, a cam fixedly connected to one end of the connecting shaft, a protrusion fixedly connected around the outer wall of the cam, a transmission wheel fixedly connected to the other end of the connecting shaft, and a transmission belt drivingly connecting the transmission wheel and the drive wheel.

[0006] As a preferred embodiment of this utility model, a feed frame is fixedly connected to the top of the crushing frame, and a secondary crushing shaft is rotatably connected to the inner wall of the crushing frame. Multiple crushing blades are fixedly connected to the outer walls of both the secondary crushing shaft and the main crushing shaft.

[0007] As a preferred embodiment of this utility model, a main gear is fixedly connected to one end of the main crushing shaft near the drive wheel, one end of the auxiliary crushing shaft extends out of the outer wall of the crushing frame, and an auxiliary gear is fixedly connected to the extended end of the auxiliary crushing shaft, the auxiliary gear meshing with the main gear.

[0008] As a preferred embodiment of this utility model, a base is fixedly connected to the upper surface of the waste removal platform, and a motor is fixedly connected to the top of the base. The output end of the motor is fixedly connected to one end of the main crushing shaft.

[0009] As a preferred embodiment of this utility model, a limiting block is fixedly connected to the lower surface of the waste removal platform, and a spring is fixedly connected to the bottom end of the limiting block. The bottom end of the spring is fixedly connected to the upper surface of the vibration frame.

[0010] As a preferred embodiment of this utility model, the outer wall of the vibration frame is symmetrically fixedly connected with two threaded blocks, and the inner wall of the threaded blocks is threadedly connected with fixing bolts.

[0011] As a preferred embodiment of this utility model, a handle is fixedly connected to the front end of the screen, a collection funnel is fixedly connected to the bottom end of the waste removal platform, and a guide frame is provided on the inner wall of the waste removal platform.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. Compared with traditional devices, this utility model utilizes a vibrating frame at the bottom of the crushing frame. By using a cam to drive the protrusion to periodically push the push wheel, and with the restoring force of the spring, the vibrating frame causes the screen to generate high-frequency reciprocating vibration. This effectively breaks up the PVC medicine bag crushed material that causes screen blockage due to slight stickiness. At the same time, the inertial force generated by the vibration can separate aluminum-plastic composite layer fragments that may be contained in the crushed material, improving the material recycling efficiency and ensuring the cleanliness of the recycled material.

[0013] 2. Compared with traditional devices, this utility model has a drive wheel and a transmission wheel set at one end of the cam and the main crushing shaft, which allows the operator to drive the crushing operation of the crushing shaft and the vibration operation of the vibrating frame simultaneously with just a motor. This makes operation and maintenance convenient. At the same time, the combination structure of the vibrating frame and the screen can be quickly disassembled and assembled by a pull-out connection. The operator only needs to thread the fixing bolts to the inner wall of the threaded block to achieve quick installation, which is convenient for cleaning the screen. Attached Figure Description

[0017] like Figures 1 to 5 As shown, this utility model provides a waste removal device for the production of PVC medicine packaging materials, including a waste removal platform 1. A crushing frame 2 is fixedly connected to the top of the waste removal platform 1. A main crushing shaft 4 is rotatably connected to the inner wall of the crushing frame 2. A crushing blade 6 is fixedly connected to the outer wall of the main crushing shaft 4. Two drive wheels 10 are symmetrically fixedly connected to the end of the main crushing shaft 4 away from the crushing blade 6. Two hinge seats 15 are symmetrically fixedly connected to the bottom of the waste removal platform 1. A vibrating frame 16 is hinged to the inner wall of the two hinge seats 15. A screen 20 is slidably connected to the inner wall of the vibrating frame 16. Two push wheels 17 are symmetrically fixedly connected to the top of the screen 20. Two bearing blocks 13 are symmetrically fixedly connected to the lower surface of the waste removal platform 1. A connecting shaft 1401 is rotatably connected to the inner wall of the bearing blocks 13. A cam 14 is fixedly connected to one end of the connecting shaft 1401. A protrusion 1402 is fixedly connected around the outer wall of the cam 14. A transmission wheel 11 is fixedly connected to the other end of the connecting shaft 1401. A transmission belt 12 is connected between the transmission wheel 11 and the drive wheel 10.

[0018] The top of the crushing frame 2 is fixedly connected to the feed frame 3, and the inner wall of the crushing frame 2 is rotatably connected to the auxiliary crushing shaft 401. Multiple crushing blades 6 are fixedly connected to both the auxiliary crushing shaft 401 and the outer wall of the main crushing shaft 4.

[0019] Among them, the main crushing shaft 4 is fixedly connected to the main gear 7 at one end near the drive wheel 10, and the auxiliary crushing shaft 401 extends out of the outer wall of the crushing frame 2 at one end. The extended end of the auxiliary crushing shaft 401 is fixedly connected to the auxiliary gear 701, and the auxiliary gear 701 meshes with the main gear 7.

[0020] It should be noted that when the main crushing shaft 4 rotates, the main crushing shaft 4 meshes with the main gear 7 through the secondary gear 701, driving the secondary crushing shaft 401 to rotate synchronously in the opposite direction. At the same time, the main crushing shaft 4 and the secondary crushing shaft 401 drive the interlaced crushing blades 6 to rotate in the opposite direction, and the rotation of the crushing blades 6 continues to crush the PVC medicine package material.

[0021] Among them, a base 501 is fixedly connected to the upper surface of the waste removal platform 1, and a motor 5 is fixedly connected to the top of the base 501. The output end of the motor 5 is fixedly connected to one end of the main crushing shaft 4.

[0022] It should be noted that motor 5 is based on the MSMD servo motor. The base 501 is used to support the operation of motor 5. After motor 5 is started, motor 5 drives the main crushing shaft 4 to rotate through the output end, thereby performing the crushing work.

[0023] Among them, a limiting block 19 is fixedly connected to the lower surface of the waste removal platform 1, and a spring 18 is fixedly connected to the bottom end of the limiting block 19. The bottom end of the spring 18 is fixedly connected to the upper surface of the vibration frame 16.

[0024] It should be noted that when the vibrating frame 16 is pushed by the cam 14 through the pusher wheel 17, the front end of the vibrating frame 16 will rotate around the hinge seat 15. When rotating, the front end of the screen 20 will pull the spring 18. When the vibrating frame 16 loses the thrust of the protrusion 1402, the front end of the vibrating frame 16 will vibrate under the elastic force of the spring 18, thereby driving the screen 20 to vibrate.

[0025] Among them, the outer wall of the vibration frame 16 is symmetrically fixedly connected with two threaded blocks 21, and the inner wall of the threaded blocks 21 is threadedly connected with fixing bolts 22.

[0026] It should be noted that threaded holes are symmetrically provided on the outer wall of the screen 20. When the screen 20 needs to be fixed to the inner wall of the vibrating frame 16, the fixing bolts 22 pass through the screen 20 and are threadedly connected to the threaded holes. The screen 20 and the vibrating frame 16 are fixed by the connection of the two fixing bolts 22.

[0027] Among them, the front end of the screen 20 is fixedly connected to a handle 23, the bottom end of the waste removal platform 1 is fixedly connected to a collection funnel 9, and the inner wall of the waste removal platform 1 is provided with a guide frame 8.

[0028] It should be noted that a sliding groove is provided on the inner wall of the vibrating frame 16, and a sliding strip is provided on the outer wall of the screen 20. The screen 20 slides along the sliding groove on the inner wall of the vibrating frame 16 via the sliding strip. The operator can pull the screen 20 along the inner wall of the vibrating frame 16 by pulling the handle 23.

[0029] Working principle and usage process of this utility model: The specific operation is as follows: The operator needs to start motor 5. Motor 5 drives the main crushing shaft 4 to rotate through the conveyor end. The main crushing shaft 4 further drives the main gear 7 and drive wheel 10 to rotate. When the main gear 7 rotates, it drives the auxiliary gear 701 to rotate through meshing. The auxiliary gear 701 further drives the auxiliary crushing shaft 401 to rotate. The auxiliary crushing shaft 401 and the main crushing shaft 4 will synchronously drive the crushing blade 6 to rotate synchronously and oppositely on the inner wall of the crushing frame 2. At this time, the operator needs to put the PVC medicine bag material into the inner wall of the crushing frame 2 through the feed box 3. The PVC medicine bag material is crushed under the rotation of the crushing blade 6. The crushed PVC medicine bag material will fall on the top of the screen 20 of the guide frame 8. At the same time, the drive wheel 10 rotates and drives the transmission wheel 11 to rotate through the transmission belt 12. 11 further drives the connecting shaft 1401 to rotate on the inner wall of the bearing block 13. At the same time, the connecting shaft 1401 drives the cam 14 to rotate. The cam 14 drives multiple protrusions 1402 to perform circular motion. The protrusions 1402 periodically push the push wheel 17 through circular motion. When pushed, the push wheel 17 pushes the vibrating frame 16 to rotate around the hinge point of the hinge seat 15. When the vibrating frame 16 rotates, it pulls the spring 18 at the front end. During the push interval of multiple protrusions 1402, the spring 18 pulls the front end of the vibrating frame 16 back to its original position through elastic force, thereby realizing the vibration of the vibrating frame 16. The vibrating frame 16 drives the screen 20 to vibrate. Through vibration, the crushed PVC medicine bag material is screened. Finally, the crushed PVC medicine bag material is collected and recycled in the drop collection funnel 9.
