Description

Technical Field

[0001] This invention belongs to the field of solid waste recycling technology, and in particular relates to a waste recycling device for waterproof membrane production. Background Technology

[0002] Waterproof membranes are a core material in building waterproofing projects, widely used in roofs, basements, tunnels, and other waterproofing applications. With the increasing popularity of resource recycling concepts, the recycling and reuse of waste materials from waterproof membrane production has become an inevitable trend in the industry. Crushing is a crucial step in the waste recycling process, transforming large pieces of waste into granular or fragmented materials, facilitating subsequent reprocessing.

[0003] The performance of waste waterproof membrane materials is affected by various factors such as ambient temperature and humidity, duration of sunlight exposure, and storage period. Some waste materials exhibit varying degrees of aging and deterioration, with ordinary synthetic resin-based waterproof membranes showing the most pronounced aging phenomenon. If this aged waste is directly mixed with unaged or lightly aged membrane waste for crushing and recycling, the quality of the recycled waterproof membrane will be severely degraded, resulting in key performance indicators failing to meet engineering application requirements. Therefore, before crushing waste waterproof membrane materials, their aging degree must be rigorously tested, and severely aged waste must be screened and discarded, selecting only qualified waste for recycling.

[0004] Currently, the aging degree of waterproof membrane waste is mainly tested using simple equipment for bending tests. The specific procedure involves bending the waste membrane using existing equipment and observing whether cracks or brittle fractures appear on the surface to determine its aging degree. However, this traditional bending test method lacks a unified quantitative standard, relying heavily on experience to define the degree of aging. Furthermore, the control of key operational parameters such as bending force and angle lacks precision, leading to significant differences in parameter settings among different testers and equipment. This results in inconsistent test results, easily causing misjudgments or omissions, and making it impossible to accurately distinguish between light, moderate, and severe aging levels of membrane waste. Summary of the Invention

[0005] To overcome the aforementioned drawbacks, the present invention provides a waste recycling device for the production of waterproof membrane rolls.

[0006] The technical solution of the present invention is as follows: a waste recycling device for waterproof membrane production, comprising a shell, a slitting module installed inside the shell, a fixed frame fixedly connected to the shell, a drive frame slidably connected to the fixed frame, a cutting blade fixedly connected to one side of the drive frame, an extrusion plate fixedly connected to the other side of the drive frame, a drive push rod fixedly connected to the fixed frame, the telescopic end of the drive push rod fixedly connected to the drive frame, symmetrically distributed mounting sleeves rotatably connected inside the shell, circumferentially arrayed shaping components fixedly connected between the symmetrically distributed mounting sleeves, a first motor installed inside the shell, the output shaft of the first motor fixedly connected to one of the mounting sleeves, and the bending detection of the material is performed by utilizing the relative movement between the extrusion plate and two adjacent shaping components.

[0009] More preferably, it further includes a separation mechanism disposed within the outer casing for removing impurities from the surface of the material. The separation mechanism includes: a receiving shell slidably connected within the outer casing; a screening plate fixedly connected within the outer casing, with both the guide plate and the screening plate located above the receiving shell; rotating frames symmetrically distributed and rotatably connected to the outer casing, with connecting rods fixedly connected between the symmetrically distributed rotating frames; and kneading components circumferentially distributed and disposed between the symmetrically distributed rotating frames for deforming the material.

[0010] More preferably, the kneading assembly includes: a first piece rotatably connected to one of the rotating frames; a second piece fixedly connected to the other rotating frame; a first clamping strip fixedly connected to the first piece and slidably connected to the second piece, wherein a first elastic element is provided between the first clamping strip and the second piece; and a second clamping strip fixedly connected to the second piece and slidably connected to the first piece, wherein a second elastic element is provided between the second clamping strip and the first piece.

[0011] More preferably, both the first clamping strip and the second clamping strip are elastic.

[0012] More preferably, the first clamping strip and the corresponding second clamping strip are provided with arrayed extrusion blocks on their opposite sides.

[0013] More preferably, the extrusion blocks on the first clamping strip and the extrusion blocks on the corresponding second clamping strip are staggered.

[0014] More preferably, a second motor is fixedly connected inside the housing, and the output shaft of the second motor is fixedly connected to the rotating frame near the first block; a mounting plate is fixedly connected inside the housing, and a gear ring is rotatably connected to the mounting plate; an internal gear is fixedly connected to the first block, and the internal gear meshes with the gear ring; a third motor is fixedly connected inside the housing, and an external gear is fixedly connected to the output shaft of the third motor, and the external gear meshes with the gear ring.

[0015] More preferably, a belt conveyor module is installed inside the housing, and the symmetrically distributed guide plates are all fixedly connected to the belt conveyor module. The belt conveyor module is located below all the shaping parts. An extrusion roller is rotatably connected inside the housing and is located above the belt conveyor module.

[0016] Compared with the prior art, the present invention has the following advantages: The present invention applies a fixed extrusion force to the roll material by the reciprocating movement of the extrusion plate, and uses the support of two corresponding shaping parts to bend the roll material at a fixed angle, thereby achieving precise control of the bending force and bending angle of the roll material, reducing the probability of misjudgment and omission, and accurately distinguishing the degree of aging of the roll material.

[0017] The present invention uses the twisting of the first and second clamping strips to drive the roll material between them to twist synchronously, so that the roll material applies shearing force to the impurities on its surface, causing the impurities to detach from the roll material. Furthermore, the relative movement of the first and second clamping strips is used to rub the roll material, further improving the efficiency of impurity removal.

[0018] This invention applies pressure to impurities on the surface of the roll material by pressing the extrusion block, thereby breaking the impurities and facilitating their separation from the roll material. Attached Figure Description

[0021] First, it should be pointed out that in different described embodiments, the same components are given the same reference numerals or the same component names, and the disclosure contained throughout the specification can be applied in meaning to the same components having the same reference numerals or the same component names. Example 1

[0022] Currently, the detection of the aging degree of waterproof membrane waste mainly relies on the bending test method. This involves repeatedly bending the waste membrane manually or using simple mechanical structures to observe whether the membrane exhibits cracking, brittle fracture, delamination, or other phenomena, thereby determining its aging degree. However, the existing manual bending test method depends entirely on the operator's experience and judgment, which is highly subjective. Different operators have different control over the bending force and angle, resulting in poor consistency of test results, easy misjudgment or omission, and an inability to accurately distinguish between membrane waste of different aging levels.

[0023] A waste recycling device for waterproof membrane production, such as Figures 1-6As shown, the device includes a housing 1, a slitting module 2 installed inside the housing 1, a fixed frame 3 fixedly connected to the housing 1, a drive frame 4 slidably connected to the fixed frame 3, a cutting blade 5 fixedly connected to one side of the drive frame 4, an extrusion plate 6 fixedly connected to the other side of the drive frame 4, a drive push rod 7 fixedly connected to the fixed frame 3, the telescopic end of the drive push rod 7 fixedly connected to the drive frame 4, symmetrically distributed mounting sleeves 8 rotatably connected inside the housing 1, circumferentially arrayed shaping parts 9 fixedly connected between the symmetrically distributed mounting sleeves 8, a first motor 10 installed inside the housing 1, the output shaft of the first motor 10 fixedly connected to one of the mounting sleeves 8, and the bending detection of the material is performed by the relative movement between the extrusion plate 6 and two adjacent shaping parts 9; the extrusion plate 6 is provided with symmetrically distributed inclined extrusion surfaces, and the shaping parts 9 are provided with receiving inclined surfaces on both sides.

[0024] In the above scheme, an automatic detection method for the aging degree of the roll material is proposed, which improves the efficiency of roll material recycling. The upper left side of the outer shell 1 is provided with a feed port, and the front side of the outer shell 1 is provided with a control module. The control module is electrically connected to all electrical components in this paper. The slitting module 2 is an existing device used to cut the whole roll material into several strips (strip roll material). It mainly includes a conveyor belt, an array of circular cutting blades, and multiple positioning rollers. The cutting blade 5 and the slitting module 2 work together to cut the roll material, so that the whole roll material is evenly divided into several block roll materials of fixed size. The cutting blade 5 is located on the left side of the drive frame 4. The extrusion plate 6 is used to extrude the block roll material. The extrusion plate 6 is located on the right side of the drive frame 4. The drive push rod 7 is an existing electric push rod. There are two mounting sleeves 8, which are distributed front and back. There are six shaping parts 9. The shaping parts 9 are used to receive the roll material. The extrusion plate 6 is located directly above the two uppermost shaping parts 9.

[0025] When recycling the roll material, the roll material is placed onto the slitting module 2 through the feed port of the outer casing 1. At this time, the slitting module 2 is activated, and the slitting module 2 moves the roll material to the right. After the roll material is evenly divided by the slitting module 2, the strip roll material continues to move to the right. When the right side of the strip roll material contacts the shaping part 9 on the upper left side, the slitting module 2 stops working, the drive push rod 7 is activated, and the drive frame 4 moves downward. The drive frame 4 moves the cutting blade 5 and the extrusion plate 6 downward. The cutting blade 5 cuts the strip roll material below it, dividing the right side of the strip roll material into independent blocks. Then, the extension end of the drive push rod 7 moves upward, causing the cutting blade 5 and the extrusion plate 6 to move upward and reset. At this time, the slitting module 2 and the first motor 10 are activated. The slitting module 2 moves the strip roll material to the right, and the strip roll material pushes the block roll material to the right. The output shaft of the first motor 10 drives the front mounting sleeve 8 to rotate clockwise. Figure 4 (Based on the front view perspective), the front mounting sleeve 8 drives all the shaping parts 9 to rotate synchronously, and the shaping part 9 on the upper left gradually adheres to the block roll material.

[0026] During the rotation of the shaping component 9, when the upper left shaping component 9 rotates to the upper right, the first motor 10 stops. At this time, the block roll material is located above the two uppermost shaping components 9 and directly below the extrusion plate 6. The strip roll material contacts the shaping component 9 located on the upper left. The slitting module 2 stops working and activates the drive push rod 7. Then, the cutting blade 5 and the extrusion plate 6 move downward synchronously. The cutting blade 5 repeats the above operation to cut the strip roll material located below it.

[0027] As the extrusion plate 6 moves downward, when it comes into contact with the block roll material below it, the extrusion plate 6 extrudes the block roll material. During this process, the extrusion plate 6 gradually enters between the two uppermost shaping members 9. Under the extrusion action of the extrusion plate 6, the block roll material gradually comes into contact with the receiving inclined surfaces of the two shaping members 9, thereby causing the block roll material to gradually bend.

[0028] If the portion of the roll material ages during the compression process, the roll material will break directly. If the portion of the roll material does not age, the roll material will gradually bend and come into contact with the extrusion inclined surface of the extrusion plate 6 and the receiving inclined surface of the corresponding shaping part 9.

[0029] After the block roll material is extruded, the drive push rod 7 moves upward and resets the cutting blade 5 and the extrusion plate 6. Then, the slitting module 2 and the first motor 10 are started. The slitting module 2 drives the strip roll material to move to the right and pushes the block roll material to the right. At the same time, all the shaping parts 9 rotate clockwise. The two top shaping parts 9 drive the bent roll material to move. The shaping part 9 located on the upper left gradually contacts the subsequent block roll material until the shaping part 9 on the upper left rotates to the upper right. The above operation is repeated to cut the strip roll material and to extrude and detect the block roll material.

[0030] like Figure 2 and Figures 4-6 As shown, the symmetrically distributed mounting sleeves 8 are rotatably connected to the fixed frame 11. The fixed frame 11 is fixedly connected to the outer shell 1. The flow divider 12 is fixedly connected inside the fixed frame 11. The outer shell 1 is provided with symmetrically distributed guide plates 13. The symmetrically distributed guide plates 13 are located on both sides of the flow divider 12. In this embodiment, the guide plates 13 are fixedly connected to the outer shell 1.

[0031] The above scheme proposes a method for collecting aged roll material. The diverter 12 has two symmetrically distributed guide inclined surfaces, and there are two guide plates 13. During the extrusion process of the extrusion plate 6, the aged roll material will break. The broken roll material moves downward and loses contact with the corresponding two shaping parts 9. The broken roll material moves downward and falls onto the diverter 12 below. The diverter 12 is used to guide the aged roll material, causing the broken roll material on it to slide forward and backward on both sides, thus diverting the flow. Plate 13 is used to guide the roll material on the diverter 12. During the extrusion of the roll material, the aged roll material falling off the guide plate 13 is collected. During the rotation of all the shaping parts 9, the two adjacent shaping parts 9 drive the bent block roll material between them to rotate until the bent block roll material rotates to the lower side. Under the action of gravity, the bent block roll material falls off. Then the block roll material is collected. After all the roll materials have completed bending, the slitting module 2, the drive push rod 7 and the first motor 10 are turned off. Example 2

[0032] After the roofing membrane is removed from the building, impurities from the building's surface, such as wall plaster, adhere to its inner surface. When the membrane is broken, these impurities mix with it, directly causing them to mix with subsequent recycled roofing membrane materials. This results in a decrease in the tensile strength and elongation at break of the recycled roofing membrane. At the same time, during the use of the roofing membrane, its outer surface ages before its inner surface. If only the outer surface ages (mild aging), existing simple bending testing equipment cannot detect it, thus failing to remove that part of the roofing membrane, which affects the subsequent recycled roofing membrane.

[0033] Based on Example 1, such as Figures 1-4 and Figure 7 As shown, it also includes a separation mechanism, which is set inside the outer shell 1, for removing impurities from the surface of the material. The separation mechanism includes: a receiving shell 21, which is slidably connected inside the outer shell 1; a screening plate 22, which is fixed inside the outer shell 1, and both the guide plate 13 and the screening plate 22 are located above the receiving shell 21; a rotating frame 23, which is symmetrically distributed and rotatably connected to the outer shell 1, and a connecting rod is fixed between the symmetrically distributed rotating frames 23; and a kneading component, which is circumferentially distributed and is set between the symmetrically distributed rotating frames 23, for deforming the material.

[0034] The above solution proposes a method for processing curved block rolls to remove surface impurities. The receiving shell 21 is divided into four sections, consisting of two front and rear shells and two left and right shells. The front and rear shells correspond to two guide plates 13 respectively. The left shell is located below the screening plate 23 and is used to collect impurities. The right shell is located to the right of the screening plate 23 and is used to collect the cleaned rolls. There are two rotating frames 23, which are distributed front and back. There are four kneading components.

[0035] like Figures 7-11 As shown, the kneading assembly includes: a first block 31, rotatably connected to the front rotating frame 23; a second block 32, fixedly connected to the rear rotating frame 23; a first clamping strip 33, fixedly connected to the first block 31 and slidably connected to the second block 32, with a first elastic element, which is a spring, provided between the first clamping strip 33 and the second block 32; and a second clamping strip 34, fixedly connected to the second block 32 and slidably connected to the first block 31, with a second elastic element, which is a spring, provided between the second clamping strip 34 and the first block 31. The first and second elastic elements are used to adapt to changes in length after the first and second clamping strips 33 and 34 are twisted. Both the first and second clamping strips 33 and 34 are elastic, meaning they can deform. During the mutual twisting process, they can move relative to each other under the action of their own elasticity, thereby achieving kneading of the roll material between them. The distance between the first and second clamping strips 33 and 34 is greater than the thickness of the roll material.

[0036] like Figures 9-11 As shown, the first clamping strip 33 and the corresponding second clamping strip 34 are provided with arrayed extrusion blocks 41 on opposite sides. The extrusion blocks 41 are hemispherical and the extrusion blocks 41 extrude the roll material to increase the deformation of the roll material. The extrusion blocks 41 on the first clamping strip 33 and the extrusion blocks 41 on the corresponding second clamping strip 34 are staggered.

[0037] like Figure 2 , Figure 4 , Figure 7 , Figure 8 and Figure 12 As shown, a second motor 51 is fixedly connected inside the outer casing 1. The output shaft of the second motor 51 is fixedly connected to the front rotating frame 23. The output shaft of the second motor 51 drives the front rotating frame 23 to rotate, realizing the revolution of the first block 31. The output shaft of the second motor 51 rotates intermittently, and the rotation angle of each rotation is 90°. A mounting plate 52 is fixedly connected inside the outer casing 1. A gear ring 53 is rotatably connected to the mounting plate 52. The gear ring 53 has teeth on both its inner and outer sides. An internal gear 54 is fixedly connected to the first block 31. The internal gear 54 meshes with the teeth on the inner side of the gear ring 53. The gear ring 53 can drive the internal gear 54 to rotate, so that the corresponding first block 31 rotates relative to the front rotating frame 23. A third motor 55 is fixedly connected inside the outer casing 1. An external gear 56 is fixedly connected to the output shaft of the third motor 55. The external gear 56 meshes with the teeth on the outer side of the gear ring 53. All motors in this paper are servo motors, and the rotation speed of their output shafts can be controlled by a program.

[0038] like Figures 5-7As shown, a belt conveyor module 61 is installed inside the outer casing 1. The belt conveyor module 61 is used to drive the bent roll material to move to the left. The symmetrically distributed guide plates 13 are all fixed to the belt conveyor module 61. The belt conveyor module 61 is located below all the shaping parts 9. A pressing roller 62 is rotatably connected inside the outer casing 1. The pressing roller 62 is located above the left side of the belt conveyor module 61. The pressing roller 62 is connected to the adjacent drive roller on the belt conveyor module 61 through a gear set. The pressing roller 62 and the belt conveyor module 61 work together to press the roll material and flatten the bent roll material. The conveying efficiency of the belt conveyor module 61 corresponds to the rotation frequency of the second motor 51. When the first clamping bar 33 and the corresponding second clamping bar 34 move to the right side and align with the belt conveyor module 61, the belt conveyor module 61 conveys the roll material to contact the pressing roller 62.

[0039] The working principle of this embodiment: Following the working principle of Embodiment 1, during the process of the two adjacent shaping members 9 driving the bent roll material on them to rotate, the belt conveyor module 61 is activated. When the roll material rotates to the lower side of all the shaping members 9, the roll material moves downward under the action of gravity and separates from the corresponding two shaping members 9, falling onto the belt conveyor module 61. The belt conveyor module 61 drives the roll material to move to the left. During this process, the drive roller on the belt conveyor module 61 drives the extrusion roller 62 to rotate through the gear set. When the roll material moves to contact the extrusion roller 62, with the operation of the belt conveyor module 61, the roll material continues to move to the left, so that the roll material enters between the belt conveyor module 61 and the extrusion roller 62. During this process, the belt conveyor module 61 and the extrusion roller 62 jointly extrude the roll material, making the roll material flatten.

[0040] As the coil passes through the extrusion roller 62, it gradually enters the space between the corresponding first clamping strip 33 and second clamping strip 34 (first group). After the coil has completely passed through the extrusion roller 62, it is fully between the first clamping strip 33 and second clamping strip 34. At this time, the third motor 55 is turned on. The output shaft of the third motor 55 drives the external gear 56 to rotate in the forward direction. The external gear 56 drives the gear ring 53 to rotate in the forward direction (the forward and reverse directions in this article are used to describe the forward or reverse direction of the parts in the whole operation logic, and do not represent clockwise or counterclockwise rotation). The gear ring 53 drives all the internal gears 54 to rotate in the forward direction. Taking the internal gear 54 on the left as an example, the internal gear 54 drives the adjacent first block 31 to rotate. The first block 31 drives the front side of the first clamping strip 33 and the front side of the second clamping strip 34 on it to rotate. During this process, since the second block 32 on the rear side does not rotate, that is, the rear side of the first clamping strip 33 and the rear side of the second clamping strip 34 do not rotate, thus causing the first clamping strip 33 and the second clamping strip 34 to twist.

[0041] During the torsion of the first clamping strip 33 and the second clamping strip 34, both drive the internal roll material to twist synchronously, causing the roll material to twist in a spiral manner. During the torsion of the roll material, the surface morphology of the roll material changes, and shear force is generated on the impurities on its surface. Because the impurities are brittle, have a loose internal structure, and do not have elastic deformation ability, the impurities cannot deform synchronously with the torsion of the roll material. The bonding relationship between the impurities and the roll material is completely destroyed, thereby causing the impurities to detach from the roll material. During this process, the first clamping strip 33 and the second clamping strip 34 respectively drive all the extrusion blocks 41 on them to extrude the roll material at multiple points, causing the impurities on the surface of the roll material to break, thereby facilitating the detachment of the impurities.

[0042] During the torsion of the first clamping strip 33 and the second clamping strip 34, since the distance between the first block 31 and the second block 32 does not change, the first clamping strip 33 and the second clamping strip 34 are stretched due to their elasticity to adapt to the length change caused by the torsion until the first clamping strip 33 and the second clamping strip 34 can no longer be stretched. The first clamping strip 33 compresses the adjacent first elastic element, and the second clamping strip 34 compresses the adjacent second elastic element. During this process, the first clamping strip 33 moves relative to the second clamping strip 34. At the same time, the first clamping strip 33 and the second clamping strip 34 both drive all the extrusion blocks 41 on them to move, changing the position of the extrusion blocks 41 extruding the roll material, and further increasing the degree of impurity fragmentation.

[0043] After the internal gear 54 rotates three to five times in the forward direction, the output shaft of the third motor 55 rotates in the reverse direction, thereby driving the internal gear 54 to reset through the external gear 56 and the gear ring 53. The first clamping bar 33 and the second clamping bar 34 gradually return to their original state under their own elasticity. At the same time, under the action of the first elastic element and the second elastic element, the first clamping bar 33 and the second clamping bar 34 return to their initial position and restore the roll material to a flat state.

[0044] After the first clamping bar 33 and the second clamping bar 34 are fully reset, the output shaft of the third motor 55 continues to rotate in the opposite direction, thereby driving the internal gear 54 to continue rotating in the opposite direction through the external gear 56 and the gear ring 53. This causes the first clamping bar 33 and the second clamping bar 34 to twist in the opposite direction, thereby changing the twisting direction of the roll material and further improving the efficiency of removing impurities from the surface of the roll material. After the output shaft of the third motor 55 continues to rotate in the opposite direction for three to five turns, the output shaft of the third motor 55 rotates in the forward direction, causing the first clamping bar 33 and the second clamping bar 34 to twist in the forward direction. This process is repeated three to five times, causing the first clamping bar 33 and the second clamping bar 34 to twist back and forth.

[0045] After the first clamping bar 33 and the second clamping bar 34 have finished their reciprocating twisting, the third motor 55 stops working and the second motor 51 starts. The output shaft of the second motor 51 drives the front rotating frame 23 to rotate counterclockwise (towards...). Figure 8(Based on the front view), the front rotating frame 23 drives the rear rotating frame 23 to rotate synchronously through the connecting rod, thereby controlling all the first blocks 31 and all the second blocks 32 to rotate synchronously until the first clamping bar 33 and the second clamping bar 34 (second group) located on the lower side rotate to the right side, at which point the second motor 51 stops working.

[0046] During the counterclockwise rotation of the front rotating frame 23, the front rotating frame 23 drives the internal gear 54 to rotate. The internal gear 54 moves along the gear ring 53 and rotates on its own axis. During this process, the internal gear 54 drives the corresponding first block 31 to rotate on its own axis, thereby causing all the first clamping bars 33 and the second clamping bars 34 to twist again. After the rotating frame 23 stops rotating, the third motor 55 is turned on. The output shaft of the third motor 55 drives the internal gear 54 to rotate in the opposite direction through the external gear 56 and the gear ring 53, so that the first clamping bars 33 and the second clamping bars 34 return to their initial state.

[0047] During the rotation of the second set of first clamping strips 33 and second clamping strips 34 to the right, the first motor 10 is in operation, and the next pair of shaping members 9 drives the roll material on them to rotate downwards and fall onto the belt conveyor module 61. The belt conveyor module 61 begins to convey the roll material to the left. When the second set of first clamping strips 33 and second clamping strips 34 rotates to the right and returns to a straight state, the belt conveyor module 61 drives the roll material through the extrusion roller 62. Then the above process is repeated, so that the roll material enters between the first clamping strips 33 and second clamping strips 34, and drives the first clamping strips 33 and second clamping strips 34 to twist back and forth, thereby removing impurities from the roll material.

[0048] During the repeated operation, the rotating frame 23 rotates intermittently, causing the first clamping bar 33 and the second clamping bar 34 on it to rotate synchronously until the first clamping bar 33 and the second clamping bar 34 carry the roll material to the lower side. Under the action of gravity, the roll material falls downward and lands on the screening plate 22. The screening plate 22 guides the roll material, causing it to move into the right side shell of the receiving shell 21. At the same time, impurities pass through the screening plate 22 and enter the left side shell of the receiving shell 21. The roll material and impurities in the receiving shell 21 are collected periodically.

[0049] After the roll material is processed, turn off the second motor 51, the third motor 55 and the belt conveyor module 61.

[0050] During the bending and twisting process of the roll material by the first clamping strip 33 and the second clamping strip 34, the aged part of the outer surface of the roll material will be subjected to torsional shear force. The aged part cannot be twisted synchronously with the roll material, causing the aged part and the impurities of the roll material to detach from the surface of the roll material synchronously. At the same time, the extrusion block 41 will also extrude pressure on the aged part of the roll material, making it easier for the aged part to break, thereby improving the purity of the recycled roll material and improving the quality of the recycled roll material.

[0051] It should be understood that the above description is for illustrative purposes only and is not intended to limit the invention. Those skilled in the art will understand that variations of the invention will be included within the scope of this description.
