Description

Technical Field

[0001] This invention relates to the field of waste treatment, and more particularly to a waste textile recycling device. Background Technology

[0002] When recycling waste textiles, they must first be fed into crushing and recycling equipment for processing. Due to the inherent toughness, ductility, and tribostatic properties of textile materials, they easily become entangled on the crushing rollers of the equipment, leading to problems such as roller jamming and difficulty in starting. Current equipment for crushing and recycling waste textiles mainly relies on optimizing the geometry of the crushing rollers, such as using special blades or anti-entanglement grooves. However, this method has limited anti-entanglement effectiveness, and the problem of threads becoming entangled on the crushing roller blades or grooves still exists. Alternatively, polishing or coating the roller surface can reduce friction and entanglement; however, the coating is easily worn, its effectiveness is unsustainable, and maintenance costs are high. Therefore, there is an urgent need for a waste textile recycling device with better anti-entanglement performance. Summary of the Invention

[0003] The purpose of this invention is to provide a waste textile recycling device to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0004] According to a first aspect of the present invention, a waste textile recycling device includes: a frame; a crushing mechanism, which includes a crushing unit, the crushing unit including a crushing roller and a cleaning assembly, one end of the crushing roller being rotatably connected to the frame, the outer wall of the crushing roller being provided with a slot communicating with its interior, the slot extending axially along the crushing roller, the cleaning assembly including a mandrel disposed within the crushing roller, a slide seat disposed on the mandrel, and a cutter connected to the slide seat, the cutter extending outward from the slot from the crushing roller, the mandrel being axially movable within the crushing roller, the slide seat being axially movable along the mandrel, two crushing units being symmetrically arranged in the left-right direction, the ends of the two mandrels facing each other being movable to protrude from the two crushing rollers respectively and be connected to each other, or to be separated from each other and movable into the two crushing rollers, and at least two crushing mechanisms being arranged side by side.

[0005] This technical solution has at least the following beneficial effects: Waste textiles requiring crushing and recycling are fed between two crushing mechanisms. In each crushing mechanism, the mandrels in the left and right crushing units move to protrude from the two crushing rollers and connect to each other, forming a single crushing rotor. This creates a stable rotating structure within the frame along the left-right direction. The waste textiles are crushed by the relative rotation of the two crushing rotors in adjacent crushing units. After prolonged operation, the outer walls of the crushing rollers become entangled with threads, requiring cleaning. At this point, the two mandrels are moved away from each other, causing their ends to separate and enter the crushing rollers. Then, the slides on the mandrels move from the crushing rollers... The crushing roller, connected to the machine housing, begins to slide along the length of the slot, driving the cutter to cut and clean the threads wrapped around the outside of the crushing roller. Some uncut textile materials are also moved along the length of the slot by the cutter until they reach the end of the crushing roller, where they can fall off through the gap between the two adjacent crushing rollers. This removes the textile materials wrapped around the outside of the crushing roller. After completion, the slide block drives the cutter back to its original position, and the two spindles move closer to each other and reconnect to accurately crush and recycle the waste materials. This allows for timely cutting and removal of textile materials wrapped around the waste textiles during the crushing and recycling process. Furthermore, by pushing uncut textile materials to the end of the crushing roller, the anti-winding cleaning effect on the crushing roller is ensured, improving the stability of the waste textile recycling device.

[0006] According to some embodiments of the present invention, the cleaning assembly includes a motor and a transmission sleeve. The motor is connected to the frame, one end of the mandrel protrudes from the frame and forms a transmission section, the outer side of the transmission section has at least one edge, the transmission sleeve is connected to the outer side of the transmission section, the motor is drivenly connected to the transmission sleeve, and the slide is threadedly connected to the outer side of the mandrel. The slide is slidably connected to the crushing roller along the length direction of the mandrel. The motor, as a rotational drive source, transmits power to the transmission sleeve. Because the outer side of the transmission section has an edge, and the transmission sleeve and the transmission section cooperate with each other, the transmission sleeve can drive the mandrel to rotate synchronously. By using the transmission sleeve to fit outside the transmission section, it is also possible to ensure that the mandrel and the point of transmission of rotational power have a degree of freedom of movement along the length direction of the mandrel. Since the slide is threadedly connected to the outer side of the mandrel and slidably connected to the crushing roller, by controlling the forward and reverse rotation of the mandrel, the slide can be driven to move along the length direction of the mandrel, thereby driving the cutter to reciprocate within the slot.

[0007] According to some embodiments of the present invention, the cleaning assembly further includes a linear drive member connected to the outside of the frame. The linear drive member is throttle-connected to a transmission plate, and the transmission section is rotatably connected to the transmission plate. The linear drive member can drive the transmission plate to move axially along the mandrel. The linear drive member provides the mandrel with axial freedom of movement through the transmission plate. When it is necessary to shred waste textiles, the linear drive member drives the mandrel closer to another mandrel through the transmission plate; when it is necessary to clean tangled textile materials, the linear drive member drives the mandrel away from another mandrel through the transmission plate.

[0008] According to some embodiments of the present invention, the crushing roller includes a rotating base and an arc-shaped plate. The rotating base is rotatably connected to the frame. The mandrel passes through the rotating base. Support blocks are respectively connected to the inner side of the arc-shaped plate. The support blocks are respectively slidably connected to the rotating base along the radial direction of the mandrel. Multiple arc-shaped plates are arranged around the mandrel. A conical segment is formed on the mandrel. The outer diameter of the conical segment gradually decreases in the direction away from the rotating base. The multiple support blocks are respectively provided with guide surfaces that abut against the outer wall of the conical segment. The slot is formed between two adjacent arc-shaped plates. The cutter is respectively connected to the sliding base at the position corresponding to the multiple slots. When waste textiles need to be crushed, two adjacent mandrels are connected. The conical section on the mandrel slides against the guide surfaces of multiple support blocks, causing the support blocks to slide away from each other. This creates an open structure with multiple arc-shaped plates, allowing the textiles to be crushed using the outer side of the arc-shaped plates. When cleaning tangled textile materials, the two mandrels separate. The conical section on the mandrel releases the pressure from the support blocks, causing the textile materials tangled around the outer side of the arc-shaped plates to loosen. When the cutter comes into contact with the tangled textile materials, it can more easily push the textile materials stuck on the outer side of the arc-shaped plates to the end of the crushing roller and release them. This is especially suitable for textile materials stuck in the teeth and grooves on the outer side of the arc-shaped plates, further improving the cleaning effect on the textile materials.

[0009] According to some embodiments of the present invention, transmission grooves are respectively provided on multiple guide surfaces, and transmission protrusions are respectively provided on the conical section corresponding to the positions of the multiple transmission grooves. The multiple transmission protrusions are respectively connected to the multiple transmission grooves. When it is necessary to crush waste textiles, the multiple transmission protrusions on the conical section are connected to the transmission grooves of multiple support blocks, so that the mandrel can drive multiple arc plates to rotate synchronously. The drive source that directly drives the mandrel to rotate also drives the multiple arc plates to rotate and crush the waste textiles. When it is necessary to clean the tangled textile material, the two mandrels separate from each other, the top pressure of the conical section on the multiple support blocks is removed, so that the multiple transmission protrusions also disengage from the transmission grooves. At this time, the rotation of the mandrel no longer drives the multiple arc plates to rotate synchronously, so that the mandrel and the slide rotate relative to each other, thereby driving the cutter to move in the slot.

[0010] According to some embodiments of the present invention, a fixed sleeve is connected to the rotating base at a position outside the plurality of arc-shaped plates. Elastic elements are respectively provided between the inner side of the fixed sleeve and the plurality of arc-shaped plates, and the plurality of elastic elements have a tendency to press the plurality of arc-shaped plates towards the mandrel. When the tapered section pushes the plurality of support blocks outward, it causes the plurality of arc-shaped plates to move closer to the fixed sleeve, causing the elastic elements between the plurality of arc-shaped plates and the fixed sleeve to elastically compress. When the tapered section removes pressure on the support blocks, the elastic restoring force of the plurality of elastic elements presses the plurality of arc-shaped plates towards the mandrel, causing the overall outer diameter formed by the plurality of arc-shaped plates to automatically shrink, thereby facilitating the removal of textile material wrapped around the outside of the plurality of arc-shaped plates.

[0011] According to some embodiments of the present invention, connecting rods are rotatably connected to the inner sides of the ends of the plurality of arc-shaped plates away from the support block, and the plurality of connecting rods are rotatably connected to the outer sides of the mandrel. The plurality of connecting rods can provide support for the plurality of arc-shaped plates at the ends of the mandrel away from the conical end, making the structure of the plurality of arc-shaped plates more robust during crushing. Simultaneously, when the mandrel reciprocates, the plurality of connecting rods can drive the plurality of arc-shaped plates to provide mutual approach or distance at positions away from the support block, thereby improving overall operational stability.

[0012] According to some embodiments of the present invention, baffles are respectively connected to the ends of the plurality of arc-shaped plates away from the support block. Each of the baffles has a clearance notch corresponding to the position of the mandrel, and an movable gap is formed between adjacent baffles. An opening is formed at the ends of the plurality of arc-shaped plates away from the turntable. The baffles can then cover the opening, effectively reducing the amount of broken waste material entering the space enclosed by the arc-shaped plates during the processing of waste textiles.

[0013] According to some embodiments of the present invention, an elastic strip is provided on the arc-shaped plate near the movable gap, and two adjacent elastic strips press against each other. The mutual pressing of the elastic strips between two adjacent arc-shaped plates effectively fills the movable gap between the two baffles, thereby further reducing the amount of crushed waste entering the space enclosed by the multiple arc-shaped plates. When the multiple arc-shaped plates approach each other, the elastic strips can be further elastically compressed and deformed, thus ensuring that the multiple arc-shaped plates have sufficient space to move closer together.

[0014] According to some embodiments of the present invention, a stop block is provided on the outer side of the ends of the plurality of arc-shaped plates near the rotary seat, and a material-blocking surface is formed on the side of the plurality of stop blocks away from the arc-shaped plates. The plurality of material-blocking surfaces extend obliquely toward the mandrel in a direction away from the rotary seat. The plurality of stop blocks can block the textile material by means of their oblique material-blocking surfaces, which helps to prevent the textile material from accumulating at the position where the plurality of arc-shaped plates are connected to the rotary seat, thereby improving the anti-winding effect on the entire crushing roller.

Detailed Implementation

Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them.

Furthermore, all connection relationships mentioned herein do not simply refer to direct connection of components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this invention can be combined interactively without contradicting each other.

[0022] Reference Figure 1 and Figure 2 According to a first aspect of the present invention, a waste textile recycling device includes: a frame 1; a crushing mechanism including a crushing unit, the crushing unit including a crushing roller 3 and a cleaning assembly, one end of the crushing roller 3 being rotatably connected to the frame 1, the outer wall of the crushing roller 3 being provided with a slot communicating with its interior, the slot extending axially along the crushing roller 3, the cleaning assembly including a mandrel 21 disposed within the crushing roller 3, a slide 22 disposed on the mandrel 21, and a cutter 23 connected to the slide 22, the cutter 23 extending outward from the slot of the crushing roller 3, the mandrel 21 being movable within the crushing roller 3. The slide block 22 can move axially along the spindle 21. Two crushing units are symmetrically arranged in the left-right direction. The ends of the two spindles 21 facing each other can be moved to protrude from the two crushing rollers 3 and connect with each other, or separate and move into the two crushing rollers 3. At least two crushing mechanisms are arranged side by side. For example, two crushing mechanisms are arranged side by side. Naturally, the outer surface of the crushing roller 3 is provided with toothed structures and grooved structures for crushing textiles. In the two crushing rollers 3 arranged side by side, the toothed structures and grooved structures can interlock with each other, thereby realizing the crushing of the incoming textiles.

[0023] In this waste textile recycling device, the waste textiles to be crushed and recycled are fed between two crushing mechanisms. In each crushing mechanism, the spindles 21 in the left and right crushing units move to protrude from the two crushing rollers 3 and are connected to each other, so that the left and right crushing rollers 3 form a whole crushing rotor. This forms a stable rotating structure in the left and right direction within the frame 1. By rotating the two crushing rotors in the two adjacent crushing units relative to each other, the fed waste textiles can be crushed. The waste textiles are crushed by the two rotating crushing rollers 3. After long-term operation, the outer wall of the crushing rollers 3 is wrapped with threads and needs to be cleaned. At this time, the two spindles 21 are moved away from each other, so that the ends of the two spindles 21 separate and enter the crushing rollers 3. Then the slides 22 on the spindles 21 move away from the crushing rollers 3. The crushing roller 3, rotatably connected to the machine housing, begins to slide along the length of the slot, driving the cutter 23 to cut and clean the threads wrapped around the outside of the crushing roller 3. Some uncut textile materials are driven by the cutter 23 to slide along the length of the slot until they move to the end of the crushing roller, where they can fall off from the gap between the two adjacent crushing rollers, thus cleaning the textile materials wrapped around the outside of the crushing roller. After completion, the slide block 22 drives the cutter 23 to return to its original position, while the two spindles 21 move closer to each other and reconnect to accurately crush and recycle waste materials. This allows for timely cutting and removal of textile materials wrapped around waste textiles during crushing and recycling, and by pushing uncut textile materials to the end of the crushing roller for removal, it ensures the anti-winding cleaning effect on the crushing roller and improves the stability of the waste textile recycling device.

[0024] Connecting the ends of the two mandrels 21 together allows the two crushing rollers 3 to form a continuous structure, improving the structural stability of the crushing rollers 3 in the middle of the casing. There are various structural forms for connecting the ends of the two mandrels 21. For example, a locking block is provided at the end of one mandrel 21, while a locking groove is provided at the end of the other mandrel 21. Alternatively, multiple strip-shaped protrusions are radially arranged at the center of the end of one mandrel 21, and multiple strip-shaped grooves are radially arranged at the center of the end of the other mandrel 21. When the ends of the two mandrels 21 abut against each other, the multiple strip-shaped protrusions are respectively engaged and connected to the multiple strip-shaped grooves, thereby realizing the connection between the ends of the two mandrels 21.

[0025] The cleaning assembly contains a drive source capable of rotating the spindle 21. In this embodiment, for example... Figure 3As shown, the cleaning assembly includes a motor 24 and a transmission sleeve 25. The motor 24 is connected to the frame 1. One end of the spindle 21 protrudes from the frame 1 and forms a transmission section 211. The outer side of the transmission section 211 is provided with at least one edge. The transmission sleeve 25 is connected to the outer side of the transmission section 211. The motor 24 is drivenly connected to the transmission sleeve 25. The slide block 22 is threadedly connected to the outer side of the spindle 21. The slide block 22 is slidably connected to the crushing roller 3 along the length direction of the spindle 21. The motor 24 serves as the rotational drive source, transmitting power to the transmission sleeve 25. Since the outer side of the transmission section 211 is provided with an edge, and the transmission sleeve 25 cooperates with the transmission section 211, the transmission sleeve 25 can drive the spindle 21 to rotate synchronously. By using the transmission sleeve 25 to fit on the outer side of the transmission section 211, it can also ensure that the spindle 21 and the transmission point of the rotational power have a degree of freedom of movement along the length direction of the spindle 21. Since the slide 22 is connected to the outer side of the spindle 21 by a thread and is slidably connected inside the crushing roller 3, by controlling the forward and reverse rotation of the spindle 21, the slide 22 can be driven to move along the length direction of the spindle 21, thereby driving the cutter 23 to reciprocate in the slot.

[0026] The cleaning assembly includes a drive source capable of moving the mandrel 21 axially. In this embodiment, the cleaning assembly further includes a linear drive 261 connected to the outside of the frame 1. The linear drive 261 is driven by a transmission plate 262, and the transmission segment 211 is rotatably connected to the transmission plate 262. The linear drive 261 can drive the transmission plate 262 to move axially along the mandrel 21. In practical applications, the linear drive 261 can be a cylinder, an electric lead screw, or a hydraulic cylinder. The linear drive 261 provides the mandrel 21 with axial freedom of movement through the transmission plate 262. When it is necessary to crush waste textiles, the linear drive 261 drives the mandrel 21 closer to another mandrel 21 through the transmission plate 262; when it is necessary to clean tangled textile materials, the linear drive 261 drives the mandrel 21 away from another mandrel 21 through the transmission plate 262.

[0027] In the above embodiments, the crushing roller 3 can be a one-piece molded structural component. However, to further improve the effect of cleaning and removing entangled materials, in this embodiment, the crushing roller 3 includes a rotating base 31 and an arc-shaped plate 32. The rotating base 31 is rotatably connected to the frame 1, and the mandrel 21 passes through the rotating base 31. Support blocks 33 are respectively connected to the inner side of the arc-shaped plate 32. The support blocks 33 are slidably connected to the rotating base 31 along the radial direction of the mandrel 21. Multiple arc-shaped plates 32 are arranged around the mandrel 21. A tapered section 212 is formed on the spindle 21. The outer diameter of the tapered section 212 gradually decreases in the direction away from the rotating seat 31. A plurality of support blocks 33 are respectively provided with guide surfaces that abut against the outer wall of the tapered section 212. A slot is formed between two adjacent arc plates 32. The cutter 23 is connected to the slide block 22 at the positions corresponding to the plurality of slots. In practical applications, a toothed structure or a grooved structure for crushing is provided on the outside of the arc plate 32. The number of arc plates 32 can be two, three, or four, etc. When waste textiles need to be crushed, two adjacent mandrels 21 are connected to each other. At this time, the conical section 212 on the mandrel 21 slides the multiple support blocks 33 away from each other by abutting against the guide surface of the multiple support blocks 33, so that the multiple arc plates 32 form an open structure. The crushing of textiles is achieved by using the outer side of the arc plates 32. When it is necessary to clean the tangled textile material, the two mandrels 21 are separated. At this time, the conical section 212 on the mandrel 21 removes the pressure that pushes the multiple support blocks 33 outward, so that the textile material tangled on the outer side of the multiple arc plates 32 is no longer tense. At this time, when the cutter 23 abuts against the tangled textile material, it can more easily push the textile material stuck on the outer side of the arc plate 32 to the end position of the crushing roller 3 and disengage it. This is especially suitable for textile materials stuck on the outer side of the arc plate 32 in the teeth and grooves used for crushing, further improving the cleaning effect of textile materials.

[0028] In practical applications, for two crushing rollers 3 arranged side by side, the crushing units on the same side can be driven by the same motor 24 to rotate the two spindles 21, and driven by the same linear drive 261 to reciprocate along the axial direction.

[0029] The rotation of the spindle 21 and the rotation of the rotating base 31 both require power input. At this time, they can be configured with independent drive sources to provide power. In order to simplify the drive structure, in this embodiment, a transmission groove is provided on a plurality of guide surfaces, and a transmission protrusion 213 is provided on the conical segment 212 corresponding to the position of the plurality of transmission grooves. The plurality of transmission protrusions 213 are respectively connected to the plurality of transmission grooves. When waste textiles need to be crushed, multiple transmission protrusions 213 on the conical section 212 are connected to the transmission grooves of multiple support blocks 33, so that the spindle 21 can drive multiple arc plates 32 to rotate synchronously. The drive source that drives the spindle 21 to rotate also drives multiple arc plates 32 to rotate and crush the waste textiles. When it is necessary to clean the tangled textile material, the two spindles 21 separate from each other, and the top pressure of the conical section 212 on the multiple support blocks 33 is removed, so that multiple transmission protrusions 213 also come out of the transmission grooves. At this time, the rotation of the spindle 21 no longer drives the multiple arc plates 32 to rotate synchronously, so that the spindle 21 and the slide 22 rotate relative to each other, thereby driving the cutter 23 to move in the slot.

[0030] After the tapered section 212 removes the top pressure on the support block 33, in order to facilitate the multiple support blocks 33 to move closer to each other, thereby reducing the overall outer diameter of the multiple arc plates 32, in this embodiment, the rotating seat 31 is connected to a fixing sleeve 34 at the position outside the multiple arc plates 32. An elastic element 35 is respectively provided between the inner side of the fixing sleeve 34 and the multiple arc plates 32. The multiple elastic elements 35 have the tendency to press the multiple arc plates 32 toward the spindle 21 respectively. The elastic elements 35 can be springs, torsion springs or rubber and other elastic structures. When the tapered section 212 pushes the multiple support blocks 33 outward, it causes the multiple arc plates 32 to move closer to the fixed sleeve 34, so that the elastic element 35 between the multiple arc plates 32 and the fixed sleeve 34 is elastically compressed; when the tapered section 212 removes the pressure on the support blocks 33, the elastic restoring force of the multiple elastic elements 35 presses the multiple arc plates 32 against the mandrel 21, so that the overall outer diameter formed by the multiple arc plates 32 automatically shrinks, thereby facilitating the removal of the textile material wrapped around the outside of the multiple arc plates 32.

[0031] To improve the stability of the curved plate 32's movement, in this embodiment, as follows: Figure 4As shown, connecting rods 27 are rotatably connected to the inner sides of the ends of the multiple arc-shaped plates 32 away from the support block 33, and the multiple connecting rods 27 are rotatably connected to the outer sides of the mandrel 21. The multiple connecting rods 27 can provide support for the multiple arc-shaped plates 32 at the ends of the mandrel 21 away from the conical end, making the structure of the multiple arc-shaped plates 32 more robust during crushing. At the same time, when the mandrel 21 reciprocates, the multiple connecting rods 27 can drive the multiple arc-shaped plates 32 to provide mutual approach or distance at positions away from the support block 33, thereby improving the overall operational stability.

[0032] In some embodiments, baffles 36 are connected to the ends of the plurality of arc-shaped plates 32 away from the support block 33, and the plurality of baffles 36 are respectively provided with clearance notches corresponding to the positions of the mandrel 21, and an movable gap is formed between two adjacent baffles 36. The plurality of arc-shaped plates 32 form an opening at the ends away from the turntable 31, and the plurality of baffles 36 can be used to block the opening, effectively reducing the amount of broken waste material entering the space enclosed by the plurality of arc-shaped plates 32 from the opening during the treatment of waste textiles.

[0033] Furthermore, an elastic strip is provided on the arc-shaped plate 32 near the movable gap, and two adjacent elastic strips press against each other. The mutual pressing of the elastic strips between two adjacent arc-shaped plates 32 effectively fills the movable gap between the two baffles 36, thereby further reducing the amount of crushed waste entering the space enclosed by the multiple arc-shaped plates 32. When the multiple arc-shaped plates 32 approach each other, the elastic strips can be further elastically compressed and deformed, thus ensuring that the multiple arc-shaped plates 32 have sufficient space to move closer together.

[0034] In addition, to reduce the amount of broken textile material entering the space enclosed by the multiple arc-shaped plates 32 through the slots, brushes can be provided on the sides of the arc-shaped plates 32 to block the slots. To further optimize the structure for sealing the slots, in this embodiment, airbags are provided on the sides of the multiple arc-shaped plates 32, and air passages extending along the slot direction are provided inside the multiple arc-shaped plates 32. Air blowing holes connected to the air passages are provided on the top side of the multiple arc-shaped plates 32 near the slots, and multiple air blowing holes are spaced apart along the length of the slots. The airbags are connected to the air passages, and a switch valve is provided at the position where the airbags connect to the air passages. Air inlet connectors are provided on the airbags. Adjacent airbags press against each other when inflated and separate when deflated. When waste textiles need to be shredded, air can be blown into the airbag through an external air source or electromagnetic air valve via the air inlet. At this time, the switch valve is closed, and the airbag is not connected to the airflow channel, causing the airbag to inflate and better fill and cover the slots formed between adjacent arc-shaped plates 32, thereby reducing the amount of shredded material entering the multiple arc-shaped plates 32 through the slots. When cleaning tangled textile materials, the switch valve is opened, allowing gas from the airbag to enter the airflow channel and be discharged outwards through multiple air holes on the top side of the arc-shaped plates 32. This causes the airbag at the slot to contract and recover, creating space for the cutter 23 to move through. The airflow from the air holes can also blow out the shredded material located at the slot, effectively reducing the amount of shredded material falling into the space between the multiple arc-shaped plates 32. In practical applications, when the switch valve is opened, air can be supplied to the airbag first, keeping it inflated and blowing out the shredded material from the air holes. Then, the air supply can be stopped, allowing the airbag to contract and recover.

[0035] When the crushing roller 3 rotates, the textile material is driven to wrap around its outer circumference and towards the position rotatably connected to the machine housing, which can easily affect the smoothness of the rotation of the rotating base 31. Therefore, in this embodiment, a stop block 37 is provided on the outer side of the ends of the multiple arc-shaped plates 32 near the rotating base 31. The sides of the multiple stop blocks 37 away from the arc-shaped plates 32 form a material-blocking surface, and the multiple material-blocking surfaces extend obliquely towards the mandrel 21 in a direction away from the rotating base 31. The multiple stop blocks 37 can block the textile material with their oblique material-blocking surfaces, which helps to prevent the textile material from gathering at the position where the multiple arc-shaped plates 32 are connected to the rotating base 31, and improves the anti-winding effect on the entire crushing roller 3.
