Description

Technical Field

[0001] This utility model relates to the field of film roll material crushing technology, and in particular to a film roll material crusher with automatic feeding. Background Technology

[0002] The film roll material crusher is a specialized device for crushing scraps, waste film, and mixed materials generated during the film roll production process. Equipped with an automatic feeding function, it primarily replaces manual feeding, avoiding the safety hazards of manual contact with sharp materials. The automatic conveyor belt mechanism ensures continuous and stable material supply, matching the crusher's crushing efficiency, reducing manual labor intensity, and improving the overall automation level and production efficiency of the processing flow.

[0003] Currently, most roll film scrap crushers first feed the film material into a hopper, which then drops onto two feeding rollers. The rotating feeding rollers feed the film material onto the saw blade of a rotating rotary cutter roller, which then pulls and cuts the film material into fragments. These fragments are then thrown against the machine wall and discharged from the discharge frame onto the conveyor belt. However, because the distance between the two feeding rollers is a fixed value, it cannot adapt to roll film scraps of different thicknesses and widths, limiting the application scenarios of the equipment and reducing the flexibility of its use. Furthermore, when dealing with roll film scraps of different specifications, the feeding roller assembly needs to be manually disassembled, increasing the time required for roll film crushing and reducing crushing efficiency.

[0004] Therefore, it is necessary to provide a new type of roll-film material crusher with automatic feeding to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a roll film material crusher with automatic feeding.

[0006] This utility model provides a roll film material crusher with automatic feeding, comprising: a support frame, a conveyor belt mounted on the support frame, a support plate fixedly connected to the top of the support frame, a crushing box mounted on the inner wall of the support plate, a hopper fixedly connected to the top of the crushing box, a sliding hole opened at the front right end of the crushing box, a rotating roller rotatably connected to the left side inside the crushing box, a feeding roller fixedly connected to the outside of the rotating roller, a speed regulating motor mounted on the rear side of the rotating roller, a gear rotatably connected to the front left end of the crushing box, and limit holes symmetrically opened on the right side inside the crushing box, with a movable connection between the inner wall of the limit holes and... Rotating roller two, with feeding roller two fixedly connected to the outside of rotating roller two, gear two fixedly connected to one end of rotating roller two, sliding block slidably connected to the inner wall of sliding hole, receiving chamber opened on the right side of the front of crushing box, elastic component installed on the inner wall of receiving chamber, rotary cutter roller symmetrically rotatably connected to the bottom of the inside of crushing box, multiple saw blades fixedly connected to the outside of rotary cutter roller, servo motor symmetrically installed on the rear of the top of support plate, support platform fixedly connected to the right side of bracket, inclined support frame installed on the top of support platform, conveyor belt installed on inclined support frame.

[0007] Preferably, the elastic component includes a spring disposed on the inner wall of the receiving chamber, and a T-shaped rod is slidably connected to the inner wall of the receiving chamber.

[0008] Preferably, the drive end of the speed-regulating motor is fixedly connected to the center of one end of the rotating roller, and the inner ring wall of the gear is fixedly connected to the outer side of the rotating roller away from the speed-regulating motor.

[0009] Preferably, gear one and gear two are meshing, and the range of movement limited by the limiting hole is always within the effective meshing range of gear one and gear two.

[0010] Preferably, the outer end of the rotating roller two away from the gear two is rotatably connected to the inner wall of the sliding block, the drive end of the servo motor is fixedly connected to the rear shaft of the rotary cutter roller, and the bottom left end of the inclined support frame is fixedly connected to the top of the hopper.

[0011] Preferably, the left end of the T-shaped rod is fixedly connected to the right end of the sliding block.

[0013] Compared with related technologies, the automatic feeding film-rolled waste material crusher provided by this utility model has the following beneficial effects: Automatic feeding enhances automation: With the help of conveyor belts and inclined support frames, the film scraps can be automatically transported to the hopper, replacing manual feeding and avoiding the safety hazards of manual contact with sharp fragments. At the same time, it achieves continuous and stable feeding, matches the crushing efficiency of the crusher, reduces the intensity of manual operation, and greatly improves the automation level and production efficiency of the overall processing flow.

[0014] Automatic feed roller adaptation enhances operational flexibility: Through a spring-loaded assembly consisting of springs, T-shaped rods, and sliding blocks, the feed roller can automatically move according to the thickness of the film scraps. Whether the film scraps are thick or thin, they can be stably conveyed. This eliminates the limitation of fixed-spacing feed rollers being unable to adapt to different specifications of scraps, greatly enhancing the application scenarios and operational flexibility of the equipment.

[0015] High-efficiency crushing ensures crushing quality: The servo motor drives the rotary cutter roller and multiple saw blades to rotate at high speed, which can quickly and evenly pull and cut the rolled film debris that is stably fed by the feed roller into fragments. Under the centrifugal force and gravity of the rotary cutter roller, the fragments can fall smoothly from the discharge area of ​​the crushing box to the conveyor belt, ensuring the high efficiency of crushing and the collection effect of crushed materials, thus improving the crushing quality.

[0018] 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 the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0019] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0020] Please see Figures 1 to 7 The support frame 1 is equipped with a conveyor belt 2, which can stably carry the crushed film scrap fragments and continuously transport them to the designated collection area using its own power, facilitating subsequent collection and processing. A support plate 3 is fixedly connected to the top of the support frame 1, and a crushing box 4 is installed on the inner wall of the support plate 3. The crushing box 4 serves as the core area for crushing film scrap. A hopper 5 is fixedly connected to the top of the crushing box 4. The hopper 5 is open, allowing the film scrap to be fed in from above. The shape and size design of the hopper 5 allow the scrap to slide smoothly into the feeding roller area inside the crushing box 4. A sliding hole 6 is provided on the front right side of the crushing box 4. A rotating roller 7 is rotatably connected to the left side inside the crushing box 4. The rotating roller 7 can flexibly move within the crushing box 4. The rotating roller 7 is fixedly connected to a feeding roller 8. The surface of the feeding roller 8 has a certain friction force, which can effectively clamp and transport the film roll debris during rotation. A speed-regulating motor 9 is installed on the rear side of the rotating roller 7. The speed-regulating motor 9 can adjust the output speed according to actual needs, thereby controlling the rotation speed of the rotating roller 7 to adapt to different film roll debris conveying and crushing rhythms. A gear 10 is rotatably connected to the front left end of the crushing box 4. The drive end of the speed-regulating motor 9 is fixedly connected to the shaft center of one end of the rotating roller 7. When the speed-regulating motor 9 runs, it can directly drive the rotating roller 7 to rotate. The inner ring wall of the gear 10 is fixedly connected to the outer side of the rotating roller 7 away from the speed-regulating motor 9. Therefore, when the rotating roller 7 rotates, it will synchronously drive the gear 10 to rotate.

[0021] Limiting holes 11 are symmetrically provided on the right side of the inside of the crushing box 4. A rotating roller 12 is movably connected to the inner wall of the limiting holes 11. The limiting holes 11 restrict the movement of the rotating roller 12, ensuring that it can only move within a specific range. They also provide support for the rotation of the rotating roller 12 to accommodate film scraps of different thicknesses. A feeding roller 13 is fixedly connected to the outside of the rotating roller 12. The feeding roller 13 cooperates with the feeding roller 8 to clamp and convey the film scraps. A gear 14 is fixedly connected to one end of the rotating roller 12. Gear 10 and gear 14 are meshed, so when gear 10 rotates, it drives gear 14 to rotate, thereby causing the rotating roller 12 to rotate. The rotation of the second feeding roller 13 is limited by the movement range of the limiting hole 11, which is always within the effective meshing range of the first gear 10 and the second gear 14. This ensures that the first gear 10 and the second gear 14 can always mesh and transmit normally during the movement of the second rotating roller 12. The inner wall of the sliding hole 6 is slidably connected to the sliding block 15, which can slide freely in the sliding hole 6, providing connection and support for the movement of the second rotating roller 12. The outer end of the second rotating roller 12 away from the second gear 14 is rotatably connected to the inner wall of the sliding block 15, so that the second rotating roller 12 can move together with the sliding block 15 while rotating. The front side of the crushing box 4 is provided with a receiving chamber 16 located on the right side of the sliding hole 6. The receiving chamber 16 provides space for the installation of the elastic component.

[0022] An elastic component is installed on the inner wall of the receiving chamber 16. This component provides elastic force for the movement of the rotating roller 12, allowing the feeding roller 13 to automatically adjust its position according to the thickness of the film scrap. The elastic component includes a spring 17, which is disposed on the inner wall of the receiving chamber 16. The spring 17 has the ability to elastically deform and can generate elastic force when compressed. A T-shaped rod 18 is slidably connected to the inner wall of the receiving chamber 16. The T-shaped rod 18 can slide within the receiving chamber 16, transmitting the elastic force of the spring 17. The left end of the T-shaped rod 18 is fixedly connected to the right end of the sliding block 15, so that when the T-shaped rod 18 slides, it drives the sliding block 15 to slide together. One end of the spring 17 is fixedly connected to one side of the inner wall of the receiving chamber 16, and the other end of the spring 17 is fixedly connected to the side of the T-shaped rod 18 away from the sliding block 15. When the T-shaped rod 18 moves, it compresses or stretches the spring 17, which in turn generates a corresponding elastic force acting on the T-shaped rod 18. Shaped rod 18 and sliding block 15.

[0023] A rotary cutter roller 19 is symmetrically and rotatably connected to the bottom of the crushing box 4. The rotary cutter roller 19 can rotate at high speed inside the crushing box 4 to cut and crush the rolled film debris. Multiple saw blades 20 are fixedly connected to the outside of the rotary cutter roller 19. The saw blades 20 are distributed in a ring outside the rotary cutter roller 19, and the saw blades 20 have sharp cutting edges. When the rotary cutter roller 19 rotates, it can quickly hook and cut the rolled film debris into fragments. A servo motor 21 is symmetrically installed on the rear side of the top of the support plate 3. The servo motor 21 can precisely control the output speed and torque. The drive end of the servo motor 21 is fixedly connected to the rear shaft of the rotary cutter roller 19. When the servo motor 21 is running, it can drive the rotary cutter roller 19 and the saw blades 20 to rotate at high speed.

[0024] Support platform 22 is fixedly connected to the right side of bracket 1. Support platform 22 provides stable support for inclined support frame 23. Inclined support frame 23 is installed at the top of support platform 22. Inclined support frame 23 is set at a certain angle to facilitate the film scraps to slide down its surface under its own gravity. The bottom left side of inclined support frame 23 is fixedly connected to the top of hopper 5, so that the film scraps sliding down from inclined support frame 23 can directly enter hopper 5. Conveyor belt 24 is installed on inclined support frame 23. Conveyor belt 24 can continuously transport film scraps to inclined support frame 23 to realize automatic feeding.

[0025] The working principle of the roll film crusher with automatic feeding provided by this utility model is as follows: After the device is started, the conveyor belt 24 begins to run, continuously conveying the film scraps to the inclined support frame 23. Under its own conveying power and the inclined angle, the film scraps slide down the inclined support frame 23 and eventually enter the hopper 5. Next, the speed-regulating motor 9 starts to work, driving the rotating roller 7 to rotate. When the rotating roller 7 rotates, it drives the feeding roller 8 to rotate synchronously and also drives the gear 10 to rotate. Since the gear 10 and the gear 2 14 are meshed, the rotation of the gear 10 drives the gear 2 14 to rotate, which in turn drives the rotating roller 2 12 to rotate. The rotation of the rotating roller 2 12 then drives the feeding roller 2 13 to rotate. At this time, the film scraps in the hopper 5 fall between the feeding roller 8 and the feeding roller 2 13. Under the rotation of the feeding roller 8 and the feeding roller 2 13, the film scraps are continuously conveyed to the lower part of the crushing box 4. When encountering film scraps of varying thicknesses, if the scraps are thicker, they will compress the second feeding roller 13 during transport between the first feeding roller 8 and the second feeding roller 13. This compression will cause the second rotating roller 12 to move. As the second rotating roller 12 moves, its sliding block 15 slides within the sliding hole 6. This sliding block 15 pushes the T-shaped rod 18, which in turn compresses the spring 17 within the receiving chamber 16. The compressed spring 17 generates elastic force, which is transmitted to the second rotating roller 12 via the T-shaped rod 18 and the sliding block 15. This ensures that the second feeding roller 13 maintains good contact with the film scraps, guaranteeing stable transport of film scraps of varying thicknesses. If the film scraps are thinner, the spring 17 will push the T-shaped rod 18 to move. The movement of the rod 18 causes the sliding block 15 to slide, which in turn causes the rotating roller 12 to move. The movement of the rotating roller 12 causes the feeding roller 13 to move closer to the feeding roller 8, thus ensuring stable feeding of thinner roll film scraps. Then, the servo motor 21 starts working, driving the rotary cutter roller 19 to rotate. When the rotary cutter roller 19 rotates, the multiple saw blades 20 outside it also rotate at high speed. The roll film scraps fed from between the feeding roller 8 and the feeding roller 13 will interact with the high-speed rotating saw blades. At point 20, the saw blade 20, during its rotation, uses its sharp edge to hook and cut the rolled film debris into fragments. Finally, the fragmented rolled film debris, under the centrifugal force generated by the rotation of the rotary cutter roller 19 and its own gravity, is thrown against the wall of the crushing box 4, and then falls from the discharge area below the crushing box 4, eventually landing on the conveyor belt 2. Under its own operating power, the conveyor belt 2 transports these rolled film debris fragments to the designated collection position, completing the entire crushing and conveying process of the rolled film debris.
