Description

Technical Field

[0001] This invention belongs to the field of strip waste processing, specifically a metal thin strip processing device that integrates longitudinal shearing of waste edges and collection and packaging. Background Technology

[0002] Metal slitting is a process that longitudinally cuts wide metal coils into multiple narrow strips. Its core equipment is the slitting machine, which uses rotating upper and lower pairs of disc blades to achieve high-precision slitting. This process is widely used in the automotive, electrical appliance, and packaging industries, and features high efficiency, high precision, and high material utilization, making it one of the key steps in metal sheet and strip processing.

[0003] Metal slitting processes generate unusable edge material on both sides, known as scrap. These scrap edges can be processed in two ways by the corresponding recycling equipment: coiling them into high-density spheres, suitable for thin, tough ordinary steel, facilitating stacking and offering high recycling value; and crushing them into short sections, suitable for thick or brittle high-strength steel, avoiding strip breakage and jamming, and ensuring a more stable processing flow. Both methods work together to ensure continuous and clean operation of the production line.

[0004] Traditional slitting waste edge processing equipment is often relatively simple in function. It can only perform the same processing steps for different types of waste edges. However, there are many types of metal tracks. Selecting appropriate waste edge processing steps for different types can improve the recycling value of waste edges and adapt to different recycling needs. If only the same processing steps can be performed, it is easy to reduce recycling efficiency and recycling value.

[0005] Therefore, the present invention provides a metal strip processing device that integrates slitting of waste edges and collection and packaging. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is as follows: The present invention provides a metal strip processing device that integrates longitudinal shearing of waste edges and collection and packaging, including an outer protective cylinder and a crushing cylinder. The outer side of the crushing cylinder and the outer protective cylinder are fixedly connected by multiple connectors. The surface of the crushing cylinder is provided with multiple sieve holes. There is a screening chamber between the crushing cylinder and the outer protective cylinder. The inside of the crushing cylinder is provided with a drive cylinder that can rotate. The outer side of the drive cylinder is provided with a retractable crushing pile. The outer side of the outer protective cylinder is fixedly connected with a guide pipe. The outer side of the crushing cylinder is provided with an inlet hole communicating with the guide pipe. The top surface of the guide pipe is equipped with a pump for absorbing waste edge airflow.

[0008] This setup enables specialized processing of waste edges made of different materials, balancing high recycling value with strong material adaptability. It maximizes production line processing efficiency, and the integrated approach allows the entire processing to take place inside the crushing drum, reducing the equipment's footprint and expanding its applicability.

[0009] Preferably, the end of the guide tube is provided with an adapter groove, and the guide tube is tangentially connected to the outer wall of the outer protective cylinder along a common generatrix. Multiple outwardly flared support legs are fixed to the outer side of the outer protective cylinder. The tangential arrangement of the guide tube and the outer protective cylinder not only makes the waste edge enter the outer protective cylinder more smoothly, but also, with the adapter groove, the guide tube can be clamped at the top edge of the slitting machine, so that after the waste edge is cut out, it directly hits into the guide tube. Then, under the action of the rear thrust and negative pressure suction, the waste edge is guided to continuously enter the crushing cylinder, ensuring the smooth process of the waste edge. The outwardly flared support legs can facilitate the recycling process of the waste material below.

[0010] Preferably, the outer side of the drive cylinder is provided with a flat bonding groove, and the outer side of the bonding groove is provided with an expansion plate that can extend and retract. The surface of the expansion plate is provided with multiple ridges. When waste edge winding is required, the expansion plate will first expand outward a certain distance. As the waste edge is continuously wound around the outer side of the drive cylinder, after winding is completed, the expansion plate is controlled to retract, which greatly reduces the friction surface between the waste edge and the drive cylinder, allowing the wound waste material to fall off quickly under the action of gravity, achieving the effect of rapid material removal. The surface ridges can facilitate the waste edge to better adhere and layer on surfaces at different heights during winding.

[0011] Preferably, the drive cylinder has multiple moving slots inside, and the crushing pile is slidably engaged in the moving slots. Multiple inclined sliding rods are fixed to the side of the expansion plate near the drive cylinder. These inclined sliding rods are slidably engaged with the drive cylinder, and their inclination direction is opposite to that of the crushing pile. When it is necessary to crush waste edges, the drive cylinder rotates counterclockwise, causing the crushing pile to be thrown outwards under centrifugal force and extend to its maximum length, effectively crushing the waste edges. When it is necessary to wrap waste edges, the drive cylinder rotates clockwise. In this case, the crushing pile experiences the opposite force, and the crushing pile... It will be recycled into the moving trough, and at the same time, the inclined slide rod will slide outward, causing the expansion plate to push outward a certain distance. After the waste edge is wound up, the expansion plate no longer has the force to push outward. The expansion plate cannot maintain the outward pushing state and after slightly retracting, the wrapped waste edge can be smoothly detached from the crushing pile. An elastic element can be connected after the inclined slide rod to assist the retraction of the expansion plate. With this setting, only by changing the rotation direction of the drive cylinder, different processing modes of the device can be adjusted. In addition, the inclined slide rod and the crushing pile are set in opposite directions to ensure that they do not interfere with each other.

[0012] Preferably, the top of the drive cylinder has a fixed platform that rotates, and a drive motor is fixedly connected to the top of the fixed platform. The output end of the drive motor is connected to the drive cylinder through the fixed platform. The drive motor controls the forward and reverse rotation of the drive cylinder. The fixed platform is used to stabilize the housing of the drive motor. At the same time, the lifting and lowering of the drive cylinder can be completed by controlling the lifting and lowering of the fixed platform.

[0013] Preferably, a negative pressure fan is fixedly connected to the top of the fixed platform, and air ducts are opened at the end of the moving groove and the edge of the bonding groove. The air ducts are connected to the negative pressure fan. When it is necessary to wrap the waste edge, the negative pressure fan is turned on. The suction force generated by the negative pressure fan will act on the edge of the moving groove and the bonding groove, thereby adsorbing the waste edge and bonding it with the moving groove, ensuring that the wrapping work is carried out smoothly.

[0014] Preferably, a lifting rail is fixedly connected inside the outer protective cylinder, and a bent lifting arm is fixedly connected to the moving end of the lifting rail. The end of the lifting arm is fixedly connected to the top of the fixed platform. The lifting rail drives the lifting arm to move up and down, and the other end of the lifting arm drives the fixed platform to move up and down, thus completing the function of uniformly winding the waste edge.

[0015] Preferably, an isolation cover is fixed to the top of the fixed platform. The isolation cover is made of elastic metal. The outer edge of the isolation cover fits against the inner wall of the crushing cylinder. A closing valve is installed at the bottom of the crushing cylinder. The isolation cover is designed to reduce the problem of waste flying upwards during the crushing process. The elastic metal material can deform appropriately to absorb the impact force and can also fit tightly against the inner wall of the crushing cylinder. The closing valve is closed during crushing and remains open when wrapping the waste edge.

[0016] Preferably, the end of the crushing pile is equipped with a detachable replacement sleeve, and a shearing table facing opposite to the crushing pile is fixed to the outside of the replacement sleeve. The structure of the shearing table can improve the crushing effect of waste edges. After long-term use, only the replacement sleeve needs to be replaced.

[0017] Preferably, the vertical edge of the expansion plate is fixed with a gripping strip, which is made of elastic material and consists of multiple elastic protrusions with gaps between them. When it is necessary to wrap the waste edge, as the waste edge contacts the edge of the expansion plate, the waste edge will be stuck between two elastic protrusions. At the same time, other parts of the waste edge will also be fixed by the adsorption effect, ensuring that the waste edge can be smoothly wrapped around the outside of the drive cylinder. When the expansion plate retracts, it will squeeze the waste edge outward, allowing the waste edge to fall smoothly.

[0018] The beneficial effects of this invention are as follows:

[0019] 1. The metal strip processing device integrating longitudinal shearing and collection and packaging of waste edges described in this invention, through the setting of drive cylinder, crushing cylinder and crushing pile, realizes the function of special processing for waste edges of different materials, taking into account high recycling value and strong material adaptability, and can maximize the processing efficiency of the production line. Moreover, through the integration, the processing process is carried out in the crushing cylinder, which reduces the equipment footprint and improves the applicability of the equipment.

[0020] 2. The metal strip processing device integrating longitudinal shearing and collection and packaging of waste edges described in this invention, when waste edge winding is required, the expansion plate will first expand outward a certain distance. As the waste edge is continuously wound around the outside of the drive cylinder, after winding is completed, the expansion plate is controlled to retract, which greatly reduces the friction surface between the waste edge and the drive cylinder, allowing the wound waste material to fall quickly under the action of gravity, achieving the effect of rapid unloading; the surface ribs can facilitate the waste edge to better complete the adhesion and layering on the surface at different heights during winding.

[0031] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0032] like Figures 1 to 8 As shown in the embodiment of the present invention, a metal strip processing device integrating longitudinal shearing and collection and packaging of waste edges includes an outer protective cylinder 1 and a crushing cylinder 8. The outer side of the crushing cylinder 8 is fixedly connected to the outer protective cylinder 1 by multiple connectors. The surface of the crushing cylinder 8 is provided with multiple sieve holes 10. There is a screening chamber 13 between the crushing cylinder 8 and the outer protective cylinder 1. The interior of the crushing cylinder 8 is provided with a drive cylinder 12 that can rotate. The outer side of the drive cylinder 12 is provided with a retractable crushing pile 17. The outer side of the outer protective cylinder 1 is fixedly connected with a guide pipe 3. The outer side of the crushing cylinder 8 is provided with an inlet hole 9 that communicates with the guide pipe 3. The top surface of the guide pipe 3 is equipped with a gas flow pump 4 for absorbing waste edges.

[0033] Two of these devices are installed on either side of the metal track slitting machine. The slitting machine cuts off excess waste edges from the edges of the metal track. The position and angle of the guide tube 3 are adjusted so that it can receive the waste edges spreading out to both sides. As the slitting machine continues to operate, waste edges are continuously generated. The waste edges are pushed forward from the rear and enter the outer protective cylinder 1. At the same time, the air pump 4 can be turned on, blowing air towards the outer protective cylinder 1, thereby creating negative pressure at the end of the guide tube 3, which helps the waste edges enter the guide tube 3. The waste edges produced by different metal tracks are also different. The thickness is less than three millimeters and the waste edges have toughness, such as ordinary cold-rolled sheet, galvanized sheet, and low carbon steel. This type of metal scrap has excellent ductility, allowing it to bend continuously without breaking. The equipment utilizes this characteristic to roll it into tight, high-density cylindrical or disc-shaped scrap coils, much like rolling steel wool. The volume of the rolled scrap is significantly reduced, making it very easy to stack, transport, and store. The tight scrap coils have low transportation costs and relatively high value when sold to steel mills for remelting. By controlling the rotation of the drive cylinder 12, which has adsorption components on its surface, the scrap strips adhering to the surface of the drive cylinder 12 can be adsorbed and fixed using magnetic attraction, gripping, or negative pressure adsorption. Then, as the drive cylinder 12 rotates, the scrap strips are continuously wound up onto its outer surface. To ensure proper winding... A sufficient amount of waste strip is wound up. During the winding process, the drive cylinder 12 is controlled to move up and down, so that the waste material can be wound up relatively evenly on the outside of the drive cylinder 12. After a roll of metal track is longitudinally cut and all waste edges are wound up, the wound waste material is removed from the outside of the drive cylinder 12, waiting for the waste edges of the next roll of longitudinally cut material to be recycled. When processing metals with a thickness of more than three millimeters, high strength, and high brittleness, such as high-strength steel, some stainless steel, spring steel, and silicon steel, such waste edges are difficult to form and wind up. At this time, the crushing piles 17 on the outside of the drive cylinder 12 are controlled to extend outward, so that the waste edges entering the crushing cylinder 8 can be crushed into small pieces by the impact of the crushing piles 17 and enter the screening through the screen holes 10. The material is fed into the screening chamber 13 and leaks out from the bottom of the screening chamber 13. At this time, the bottom of the crushing cylinder 8 is in a closed state. Material that cannot pass through the screen hole 10 will remain inside the crushing cylinder 8 and be struck again by the crushing pile 17 until it can pass through the crushing cylinder 8 and move into the screening chamber 13. The crushed material can be collected from the bottom. The crushed material is convenient for subsequent remelting process and does not need to be crushed again, reducing the processing steps. Through this setting, the function of special treatment for waste edge of different materials is realized, taking into account high recycling value and strong material adaptability. It can maximize the processing efficiency of the production line. Moreover, through the integration, the processing process is carried out in the crushing cylinder 8, which reduces the equipment footprint and improves the applicability of the equipment.

[0034] The end of the guide tube 3 is provided with an adapter groove 5. The guide tube 3 is tangentially connected to the outer wall of the outer protective cylinder 1 along a common busbar. Multiple outwardly opening support legs 2 are fixed to the outer side of the outer protective cylinder 1.

[0035] During operation, the tangential arrangement of the guide tube 3 and the outer protective cylinder 1 not only makes the waste edge enter the outer protective cylinder 1 more smoothly, but also, with the matching groove 5, the guide tube 3 can be clamped at the top edge of the longitudinal cutter, so that after the waste edge is cut out, it directly hits into the guide tube 3. Then, under the action of the rear thrust and negative pressure suction, the waste edge is guided to continuously enter the crushing cylinder 8, ensuring the smooth process of the waste edge; the outward-opening support leg 2 can facilitate the recycling process of the waste material below.

[0036] The drive cylinder 12 has a flat fitting groove 23 on its outer side, and an expansion plate 20 that can extend and retract is provided on the outer side of the fitting groove 23. The surface of the expansion plate 20 is provided with multiple ridges.

[0037] During operation, when waste edge winding is required, the expansion plate 20 will first expand outward a certain distance. As the waste edge is continuously wound around the outside of the drive cylinder 12, after winding is completed, the expansion plate 20 is controlled to retract, which greatly reduces the friction surface between the waste edge and the drive cylinder 12, allowing the wound waste material to fall off quickly under the action of gravity, achieving the effect of rapid material removal. The surface ridges can facilitate the waste edge to better adhere and layer on surfaces at different heights during winding.

[0038] The drive cylinder 12 has multiple moving slots 22 inside, and the crushing pile 17 is slidably engaged in the moving slots 22. The expansion plate 20 is fixed with multiple inclined sliding rods 21 on the side near the drive cylinder 12. The inclined sliding rods 21 are slidably engaged with the drive cylinder 12, and the inclined direction of the inclined sliding rods 21 is opposite to that of the crushing pile 17.

[0039] During operation, when waste edges need to be crushed, the drive cylinder 12 rotates counterclockwise, causing the crushing pile 17 to be thrown outward under centrifugal force and extended to its maximum length, effectively crushing the waste edges. When waste edges need to be wound, the drive cylinder 12 rotates clockwise. At this time, the crushing pile 17 experiences the opposite force and will be retracted into the moving groove 22. At the same time, the inclined slide rod 21 slides outward, causing the expansion plate 20 to push outward a certain distance. After the waste edges are wound up, the expansion plate 20 no longer has the force to push outward. The expansion plate 20 cannot maintain the outward pushing state and retracts slightly, allowing the wound waste edges to be smoothly detached from the crushing pile 17. An elastic element can be connected after the inclined slide rod 21 to assist the retraction of the expansion plate 20. With this setting, different processing methods of the device can be adjusted by simply changing the rotation direction of the drive cylinder 12. Furthermore, the opposite inclination directions of the inclined slide rod 21 and the crushing pile 17 ensure that they do not interfere with each other.

[0040] The top of the drive cylinder 12 is rotatably fixed to a fixed platform 16, and the top of the fixed platform 16 is fixedly connected to a drive motor 6. The output end of the drive motor 6 is connected to the drive cylinder 12 through the fixed platform 16.

[0041] During operation, the drive cylinder 12 is rotated forward and backward by the drive motor 6. The fixed platform 16 is used to stabilize the housing of the drive motor 6. At the same time, the lifting and lowering of the drive cylinder 12 can be completed by simply controlling the fixed platform 16 to lift and lower.

[0042] A negative pressure fan 25 is fixedly connected to the top of the fixed platform 16. Air ducts are opened at the end of the moving groove 22 and the edge of the fitting groove 23, and the air ducts are connected to the negative pressure fan 25.

[0043] During operation, when it is necessary to wrap the waste edge, the negative pressure fan 25 is turned on. The suction force generated by the negative pressure fan 25 will act on the edges of the moving groove 22 and the bonding groove 23, thereby adsorbing the waste edge and bonding it with the moving groove 22, ensuring that the wrapping work is carried out smoothly.

[0044] The outer protective cylinder 1 is fixedly connected to a lifting rail 7, and the moving end of the lifting rail 7 is fixedly connected to a bent lifting arm 11. The end of the lifting arm 11 is fixedly connected to the top of the fixed platform 16.

[0045] During operation, the lifting arm 11 is raised and lowered via the lifting rail 7, and the other end of the lifting arm 11 raises and lowers the fixed platform 16, thus completing the function of uniformly winding the waste edge.

[0046] An isolation cover 15 is fixed to the top of the fixed platform 16. The isolation cover 15 is made of elastic metal. The outer edge of the isolation cover 15 is in contact with the inner wall of the crushing cylinder 8. A closing valve 14 is installed at the bottom of the crushing cylinder 8.

[0047] During operation, the isolation cover 15 is designed to reduce the problem of waste flying upwards during the crushing process. The elastic metal material can deform appropriately to absorb the impact force and can also stick tightly to the inner wall of the crushing cylinder 8. The closing valve 14 is closed during crushing and remains open when the waste edge is wrapped.

[0048] The end of the crushing pile 17 is equipped with a detachable replacement sleeve 18, and a shearing table 19 facing opposite to the crushing pile 17 is fixed to the outside of the replacement sleeve 18.

[0049] During operation, the structure of the shearing table 19 can improve the effect of crushing waste edges. After long-term use, only the replacement sleeve 18 needs to be replaced.

[0050] The vertical edge of the expansion plate 20 is fixed with a gripping strip 24, which is made of elastic material and is composed of multiple elastic protrusions with gaps between them.

[0051] During operation, when it is necessary to wrap the waste edge, as the waste edge comes into contact with the edge of the expansion plate 20, the waste edge will be stuck between the two elastic protrusions. At the same time, other parts of the waste edge will also be fixed by the adsorption effect, ensuring that the waste edge can be smoothly wrapped around the outside of the drive cylinder 12. When the expansion plate 20 retracts, it will squeeze the waste edge outward, allowing the waste edge to fall smoothly.

[0052] During operation, two of these devices are positioned on either side of the metal track slitting machine. The slitting machine cuts off excess waste edges from the metal track. The position and angle of the guide tube 3 are adjusted so that it can receive the waste edges spreading out to both sides. As the slitting machine continues to operate, waste edges are continuously generated, pushing them forward from the rear and into the outer protective cylinder 1. Simultaneously, the air pump 4 can be activated, blowing air towards the outer protective cylinder 1, creating negative pressure at the end of the guide tube 3 to assist the waste edges in entering the guide tube 3. The waste edges produced vary depending on the type of metal track; waste edges with a thickness of less than three millimeters and possessing toughness, such as those from ordinary cold-rolled steel sheets and galvanized steel sheets, are suitable. Low-carbon steel and other similar scrap metals have excellent ductility, allowing for continuous bending without breakage. The equipment utilizes this characteristic to roll them into tight, high-density cylindrical or disc-shaped scrap coils, similar to rolling steel wool. The volume of the rolled scrap is significantly reduced, making it very convenient for stacking, transportation, and storage. The tight scrap coils have lower transportation costs and relatively higher value when sold to steel mills for remelting. By controlling the rotation of the drive cylinder 12, which has adsorption components on its surface, the scrap strips adhering to the drive cylinder 12 can be adsorbed and fixed using magnetic attraction, gripping, or negative pressure adsorption. As the drive cylinder 12 rotates, the scrap strips are continuously wound up onto its outer surface. To ensure energy efficiency... Sufficient waste strips are wound up. During the winding process, the drive cylinder 12 is controlled to move up and down, allowing the waste material to be wound up relatively evenly on the outside of the drive cylinder 12. After a roll of metal track is longitudinally cut and all waste edges are wound up, the wound waste material is removed from the outside of the drive cylinder 12, awaiting the recycling of waste edges from the next roll of longitudinally cut material. When processing metals with a thickness exceeding three millimeters, high strength, and high brittleness, such as high-strength steel, some stainless steel, spring steel, and silicon steel, such waste edges are difficult to form and wind up. In this case, the crushing piles 17 on the outside of the drive cylinder 12 are controlled to extend outward, allowing the waste edges entering the crushing cylinder 8 to be crushed into small pieces by the impact of the crushing piles 17, and then enter the screen through the screen holes 10. The material is fed into the screening chamber 13 and leaks out from the bottom of the screening chamber 13. At this time, the bottom of the crushing cylinder 8 is in a closed state. Material that cannot pass through the screen hole 10 will remain inside the crushing cylinder 8 and be struck again by the crushing pile 17 until it can pass through the crushing cylinder 8 and move into the screening chamber 13. The crushed material can be collected from the bottom. The crushed material is convenient for subsequent remelting process and does not need to be crushed again, reducing the processing steps. Through this setting, the function of special treatment for waste edge of different materials is realized, which takes into account high recycling value and strong material adaptability. It can maximize the processing efficiency of the production line. Moreover, through the integration, the processing process is carried out in the crushing cylinder 8, which reduces the equipment footprint and improves the applicability of the equipment.

[0053] By tangentially setting the guide tube 3 and the outer protective cylinder 1, not only is the waste edge smoother when entering the outer protective cylinder 1, but also, with the matching groove 5, the guide tube 3 can be clamped at the top edge of the longitudinal cutter, so that after the waste edge is cut out, it directly hits into the guide tube 3. Then, under the action of the rear thrust and negative pressure suction, the waste edge is guided to continuously enter the crushing cylinder 8, ensuring the smooth process of the waste edge; the outwardly opening support leg 2 can facilitate the recycling process of the waste material below.

[0054] When waste edge winding is required, the expansion plate 20 will first expand outward a certain distance. As the waste edge is continuously wound around the outside of the drive cylinder 12, after winding is completed, the expansion plate 20 is controlled to retract, which greatly reduces the friction surface between the waste edge and the drive cylinder 12, allowing the wound waste material to fall off quickly under the action of gravity, achieving the effect of rapid unloading. The surface ridges can facilitate the waste edge to better complete the adhesion and layering on the surface at different heights during winding.

[0055] When waste edges need to be crushed, the drive cylinder 12 rotates counterclockwise, causing the crushing pile 17 to be thrown outward under centrifugal force and extended to its maximum length, effectively crushing the waste edges. When waste edges need to be wound, the drive cylinder 12 rotates clockwise. At this time, the crushing pile 17 is subjected to the opposite force and will be retracted into the moving groove 22. At the same time, the inclined slide rod 21 will slide outward, causing the expansion plate 20 to push outward a certain distance. After the waste edges are wound up, the expansion plate 20 no longer has the force to push outward. The expansion plate 20 cannot maintain the outward pushing state and retracts slightly, allowing the wound waste edges to be smoothly detached from the crushing pile 17. An elastic element can be connected after the inclined slide rod 21 to assist the retraction of the expansion plate 20. With this setting, different processing methods of the device can be adjusted by simply changing the rotation direction of the drive cylinder 12. In addition, the inclined slide rod 21 and the crushing pile 17 are set in opposite directions, so that the two will not interfere with each other.

[0056] The drive cylinder 12 is rotated forward and backward by the drive motor 6. The fixed platform 16 is used to stabilize the housing of the drive motor 6. At the same time, the lifting and lowering of the drive cylinder 12 can be completed by simply controlling the fixed platform 16 to lift and lower.

[0057] When it is necessary to wrap the waste edge, turn on the negative pressure fan 25. The suction generated by the negative pressure fan 25 will act on the edges of the moving groove 22 and the bonding groove 23, thereby adsorbing the waste edge and bonding it with the moving groove 22, ensuring that the wrapping work is carried out smoothly.

[0058] The lifting arm 11 is raised and lowered by the lifting rail 7, and the other end of the lifting arm 11 drives the fixed platform 16 to be raised and lowered, thus completing the function of uniformly winding the waste edge.

[0059] The isolation cover 15 is designed to reduce the problem of waste flying upwards during the crushing process. The elastic metal material can deform appropriately to absorb the impact force and can also stick tightly to the inner wall of the crushing cylinder 8. The closing valve 14 is closed during crushing and remains open when the waste edge is wrapped.

[0060] The structure of the shearing table 19 can improve the effect of crushing waste edges. After long-term use, only the replacement sleeve 18 needs to be replaced.

[0061] When it is necessary to wrap the waste edge, as the waste edge comes into contact with the edge of the expansion plate 20, the waste edge will be stuck between the two elastic protrusions. At the same time, other parts of the waste edge will also be fixed by the adsorption effect, ensuring that the waste edge can be smoothly wrapped around the outside of the drive cylinder 12. When the expansion plate 20 retracts, it will squeeze the waste edge outward, allowing the waste edge to fall smoothly.

[0062] The foregoing has shown and described the basic principles, main features, and advantages of the present invention.
