Description

Technical Field

[0001] The present invention relates to the technical field of pulverizers, and in particular to a pulverizer for recycling waste cloth. Background Art

[0002] The recycling of waste fabrics is the process of collecting, processing and reusing discarded fabrics or waste cuttings. This process helps to reduce the impact of waste on the environment, save resources, and promote a circular economy. Recycled waste fabrics are often used to make fillers after being crushed and cut, such as sound insulation materials or stuffed toys, so as to make full use of the scraps and reduce waste. The crushing and cutting of waste fabrics is usually done by workers placing them on a conveyor belt, which then drives the waste fabrics to the cutting equipment, where the waste fabrics are crushed and cut. The common structure of the device for crushing waste fabrics in the related art is to cut and crush the fabrics by a pair of mutually cooperating crushing rollers. Since a lot of waste threads will be generated after the waste fabrics are crushed, these waste threads cannot be completely crushed in many cases and are wrapped around the crushing rollers. Over time, this will affect the normal operation of the crushing rollers.

[0003] The Chinese patent application document with publication number CN118616173A discloses a knitted fabric cutting edge material recycling and processing equipment, including side plates, a crushing unit and a spreading mechanism. Through the cooperation between the two spreading groups 1 and the pulling group in the spreading mechanism, the spreading rod and the pulling rod pull the knitted fabric cutting edge material in the left and right directions to spread the material. At the same time, through the cooperation between the two spreading groups 2, the spreading rod pulls the knitted fabric cutting edge material in the front and back directions to spread the material, so that the knitted fabric cutting edge material after spreading is evenly distributed on the conveyor belt, which improves work efficiency and saves labor costs. A single motor provides driving force for driving the spreading mechanism and the crushing unit at the same time, and the three functions of conveying, spreading and cutting are realized through a single drive.

[0004] However, when processing large pieces of waste fabrics, the waste fabrics are directly crushed. During the crushing process, due to the large size of the waste fabric pieces, they are prone to entanglement, resulting in the machine being unable to crush them normally. Secondly, for newer defective and unqualified fabrics, they will be cut into strips when reused and can be directly used as sound insulation materials. When cutting block-shaped waste fabrics into strips, due to the relatively soft fabric itself, the cutting component will move during cutting, making it difficult to cut effectively. After cutting, the fabric is prone to incomplete cutting and sticking to each other. Summary of the Invention

[0005] The present invention provides a pulverizing device for recycling waste cloth, which aims to solve the problem in the related art that when cutting block-shaped defective cloth into strips, the cloth itself is relatively soft, which causes the cutting component to move during cutting, making it difficult to cut effectively, and the cloth is easily not cut thoroughly and sticks to each other after cutting.

[0006] The breaker rack has an eccentric shaft that is provided with an eccentric shaft, and an eccentric shaft that is provided with an eccentric shaft, and an eccentric shaft that is provided with an eccentric shaft, and an eccentric shaft that is provided with an eccentric shaft and an eccentric shaft, and an eccentric shaft that is provided with an eccentric shaft and an eccentric shaft, and an eccentric shaft that is provided with an eccentric shaft and an eccentric shaft, and an eccentric shaft that is provided with an eccentric shaft and an eccentric shaft, and an eccentric shaft that is provided with an eccentric shaft and an eccentric shaft, and an eccentric shaft that is provided with an eccentric shaft and an eccentric shaft, and an eccentric shaft that is provided with an eccentric shaft

[0007] The feed ring, cutting ring, extrusion plate, sliding plate, and mounting cavity together form a receiving chamber, allowing the fabric to enter the gap at the protruding end of the feed ring and then rotate into the receiving chamber. The extrusion plate pushes the fabric against the sliding plate, compressing and contracting the elastic member to form a stable clamping position. The cutting ring rotates, causing the cutting blade to reach the gap, where the blade tip contacts the feed ring and passes through the cutting slit between the extrusion plate and sliding plate. At this point, the fabric in the receiving chamber is immobilized by four-way pressure, allowing the cutting blade to completely sever the fabric along the slit. The chain plate structure continuously rotates, discharging the severed fabric from the discharge port. Residual waste thread moves out of the cutting area as the chain plate rotates, preventing it from tangling with the blade. This solves the problem of incomplete severing caused by displacement when cutting large pieces of fabric. The multi-point pressure in the receiving chamber maintains a stable clamping position for the fabric. The dynamic coordination between the cutting slit and the blade ensures a complete cut and prevents adhesion between fabric layers. The chain plate transmission structure enables continuous cutting while preventing waste thread from tangling with the equipment, improving the efficiency of waste fabric recycling.

[0008] Preferably, the cutting knife is hinged to the cutting ring, and the cutting knife rotates to the right after being subjected to the resistance of the fabric. A torsion spring is provided between the cutting knife and the cutting ring. The torsion spring makes the cutting knife perpendicular to the tangent of the cutting ring in a natural state. A limiting block is provided at the hinge between the cutting knife and the cutting ring to make the cutting knife perpendicular to the tangent of the cutting ring. The rotatable cutting knife structure is combined with the torsion spring, so that the blade has the ability to dynamically adjust the cutting depth during the cutting process, which not only avoids equipment overload due to fabric compaction, but also ensures that each cutting operation can be effectively cut.

[0009] Preferably, a telescopic block is provided on the side of the extrusion plate facing the fabric, the telescopic block is arranged between adjacent cutting seams, and the telescopic block is retracted into the extrusion plate along the left and right directions; a telescopic block is provided on the side of the sliding plate facing the fabric, the telescopic block is arranged between adjacent cutting seams, and the telescopic block is retracted into the sliding plate along the left and right directions. Through the telescopic block structure, alternating compression areas are formed during the cutting process, which not only keeps the fabric stable but also avoids excessive extrusion causing increased cutting resistance. The area is automatically released from the compression state after cutting is completed, and the cut fabric strips can be naturally separated.

[0010] Preferably, one end of the feeding ring close to the feeding port protrudes from the cutting ring. Before cutting, the fabric is located on the upper end surface of the protruding section of the feeding ring. A physical limit is formed by the protruding section of the feeding ring, and a stable bearing surface is established before cutting. The fabric is always in a controlled state during the conveying process. When the tool cuts in, the fabric is guided by the tool into the gap, which solves the problem of difficulty in feeding in the gap.

[0011] Preferably, the elastic member includes two guide rods and a spring. The two guide rods are horizontally arranged on the front and rear side walls of the installation cavity respectively. The spring is sleeved on the guide rods. When the sliding plate slides to the left, the spring contracts to limit the movement of the sliding plate.

[0012] Preferably, a sliding sleeve is provided on the guide rod, the sliding sleeve abuts against an end of the spring away from the sliding plate, and the initial elastic potential energy of the spring is adjusted by the sliding sleeve.

[0013] Preferably, a discharge opening for discharge of materials is formed at the left ends of the loading ring and the cutting ring, and one end of the cutting ring close to the discharge opening protrudes from the loading ring.

[0014] Preferably, the feeding ring is configured as a chain plate structure, and the extrusion block is vertically arranged to the chain plate of the feeding ring; the cutting ring is configured as a chain plate structure, and the cutting knife is hinged on the chain plate of the cutting ring.

[0015] Preferably, the telescopic block of the sliding plate is arranged obliquely, and the telescopic block is inclined to the left from top to bottom.

[0016] Preferably, the inclined surface of the telescopic block is provided with multiple rollers, which are arranged in the front-to-back direction, and multiple rollers are arranged in the up-down direction on the inclined surface of the telescopic block. By arranging multiple groups of directional rollers on the inclined surface of the telescopic block, sliding friction is converted into rolling friction, so that the cloth can quickly escape from the gap area after cutting. Especially for waste cloth with loose fibers or rough surfaces, the roller structure can prevent fibers from hooking on the inclined surface of the telescopic block and causing discharge blockage.

[0017] By adopting the above technical solution, the beneficial effects of the present invention are:

[0018] 1. The present invention is provided with a cutting knife, an extrusion plate, a sliding plate and an elastic member. The feeding ring, the cutting ring and the sliding plate cooperate to form an accommodating chamber. The elastic member is used to adjust the cloth pressure. At the same time, the cutting knife cooperates with the extrusion plate and the sliding plate to achieve stable cutting. This effectively solves the problems of easy displacement and incomplete cutting of the cloth during cutting. It has the advantages of improving cutting stability, avoiding cloth displacement and ensuring complete cutting.

[0019] 2. Through the dynamically adjusted telescopic block structure and the dynamically adjusted accommodating cavity, alternating compression zones are formed during the cutting process, which not only ensures stable cutting of the fabric, but also ensures that the accommodating cavity automatically releases the compression state after cutting is completed, and the cut fabric strips can be naturally separated and discharged.

[0032] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0033] like Figures 1 to 10 As shown, a shredding device for recycling waste cloth comprises: a frame 1 and an installation cavity 2 with left and right openings, a feeding ring 3, a cutting ring 4, an extrusion plate 31, a sliding plate 5 and a cutting knife 41 are arranged in the installation cavity 2, the feeding ring 3 is rotatably arranged at the bottom of the installation cavity 2, the cutting ring 4 is rotatably arranged at the top of the installation cavity 2, the feeding ring 3 and the cutting ring 4 are arranged parallel to each other, a gap is formed between the feeding ring 3 and the cutting ring 4 for the cloth to pass through, the cutting knife 41 is arranged on the cutting ring 4, and the end of the cutting knife 41 away from the cutting ring 4 abuts against the feeding ring 3 at the gap, the extrusion plate 31 is arranged on the feeding ring 3, and the end of the extrusion plate 31 away from the feeding ring 3 abuts against the cutting ring 4 at the gap. The sliding plate 5 is elastically installed on the side wall of the installation cavity 2 in the left and right directions. The sliding plate 5 and the extrusion plate 31 are both provided with a cutting slit 61. The feeding ring 3, the cutting ring 4, the extrusion plate 31, the sliding plate 5 and the installation cavity 2 together form an accommodating cavity. When the cutting knife 4 rotates with the cutting ring 4, it passes through the cutting slit 61 to cut the extruded fabric in the accommodating cavity.

[0034] A dynamic accommodating chamber is formed by the feeding ring 3, the cutting ring 4, the extrusion plate 31 and the sliding plate 5. During cutting, the cloth is fixed in the accommodating chamber by multi-directional pressure, which solves the problem that the cloth is easily displaced during cutting, resulting in the cloth not being cut normally, and the cloth cannot be completely cut off, causing adhesion between different cloth layers. The dynamic accommodating chamber can prevent residual waste wire from winding around the equipment, thereby improving the efficiency of waste cloth recycling and processing.

[0035] like Figures 1 to 3 As shown, the feeding ring 3 refers to a rotatable annular conveying component installed at the bottom of the installation cavity 2, and is preferably implemented by a chain plate conveyor belt. The two ends of the chain plate conveyor belt are respectively rotatably set on the frame 1. The rotation of the conveyor belt causes the cloth on the chain plate to move from the feeding end to the lower feeding end.

[0036] A chain plate structure is an annular conveying structure composed of multiple hinged plates. Specifically, it can be made of metal plates connected by pins to form a flexible, rotatable ring. This structure creates a dynamic support surface during fabric conveying through the relative rotation of the plates. The chain plates of the loading ring 3 are equipped with a squeeze plate 31, fixed to the chain plate surface at a 90-degree angle. Specifically, this squeeze plate 31 can be welded or bolted. Its function is to generate thrust perpendicular to the direction of fabric travel.

[0037] like Figure 2 、 Figure 3 and Figure 9 As shown, the cutting ring 4 is preferably a chain plate structure, and the cutting ring 4 is arranged parallel to the feeding ring 3. A gap is formed between the feeding ring 3 and the cutting ring 4 for the cloth to be crushed to pass through. A cutting knife 41 is provided on the chain plate of the cutting ring 4, and the end of the cutting knife 41 away from the cutting ring 4 abuts against the feeding ring 3. The rotation of the cutting ring 4 drives the cutting knife 41 to move along a predetermined trajectory. When the cutting knife 41 moves to the gap formed by the feeding ring 3 and the cutting ring 4, the cutting knife 41 cuts the cloth in the gap.

[0038] like Figures 2 to 9 As shown, the sliding plate 5 is slidably arranged on the front and rear side walls of the installation cavity 2 along the left and right directions. The upper and lower ends of the sliding plate 5 are respectively in contact with the chain plates of the feeding ring 3 and the cutting ring 4. The sliding plate 5, the feeding ring 3, the cutting ring 4, the extrusion plate 31 and the installation cavity 2 together form an accommodating cavity. An elastic member 7 is arranged between the sliding plate 5 and the installation cavity 2. The elastic member 7 includes two guide rods 71 and a spring 72. The two guide rods 71 are respectively arranged horizontally on the front and rear side walls of the installation cavity 2. The guide rod 71 is a rigid support component arranged horizontally along the front and rear side walls of the installation cavity 2. Specifically, it can be realized by a cylindrical metal rod. The sliding plate 5 is slidably installed on the guide rod 71. The axial direction of the guide rod 71 is parallel to the sliding direction of the sliding plate 5. The guide rod 71 constrains the movement trajectory of the sliding plate 5 by physical limitation.

[0039] The spring 72 is sleeved on the guide rod 71, one end of the spring 72 is connected to the guide rod 71, and the other end of the spring 72 is connected to the sliding plate 5. The spring 72 is preferably implemented by a coil spring or a disc spring, and its compression deformation is linearly related to the displacement of the sliding plate 5. When the sliding plate 5 slides to the left, the spring 72 contracts to limit the movement of the sliding plate 5.

[0040] By providing spring 72, when the fabric is pushed into the receiving chamber by the squeezing plate 31, the sliding plate 5, under the pressure of the fabric, moves leftward along the axis of the guide rod 71. This compresses the spring 72, generating a counteracting force. The axial restraint of the guide rod 71 ensures that the sliding plate 5 maintains a horizontal and straight trajectory, preventing deviation of the sliding plate 5 due to uneven fabric thickness. The elastic force of the spring 72 forms a dynamic balance with the squeezing force of the fabric, keeping the fabric compressed and preventing it from rebounding. As the cutting blade 41 cuts the fabric, the continuous compressive force of the spring 72 forces the fabric fibers to maintain a stable tension at the cutting seam 61, preventing incomplete cutting due to fabric relaxation.

[0041] Through the composite structure of the guide rod 71 and the spring 72, a bidirectional mechanical balance is formed while limiting the movement range of the sliding plate 5. The guide rod 71 eliminates lateral displacement deviation, and the elastic characteristics of the spring 72 dynamically adapt to changes in fabric thickness, ensuring that the fabric is in a stable and controlled state during the cutting process.

[0042] In a preferred embodiment, a supporting device is provided in the ring surrounded by the chain plate structure of the feeding ring 3 and the cutting ring 4. The supporting device is respectively provided at the lower end surface of the upper horizontal section of the feeding ring 3 and the upper end surface of the lower horizontal section of the cutting ring 4, to provide supporting force for the chain plates forming the accommodating cavity part of the cutting ring 4 and the feeding ring 3, to prevent the cutting ring 4 and the feeding ring 3 from being displaced in the upper and lower directions when squeezing the cloth, causing the cloth to loosen or displace, resulting in the cloth cut seam moving, resulting in a decrease in cutting efficiency.

[0043] The supporting device preferably provides a plurality of supporting rollers 32 on the rear side of the chain plates of the supporting ring and the feeding ring 3, and the plurality of supporting rollers 32 are arranged at equal intervals in the horizontal direction. The two ends of the supporting rollers 32 are rotatably provided on the front and rear side walls of the mounting cavity 2, and bearings are further installed at the rotating parts of the two ends of the supporting rollers 32 to reduce the resistance to the rotation of the supporting rollers 32. The diameter of the supporting rollers 32 is set to be smaller than half of the length of the chain plates in the left and right directions, so that the chain plates are in contact with the two supporting rollers 32 at the same time. When the chain plates of the feeding ring 3 and the cutting ring 4 move from right to left along the supporting device, the chain plates rotate the supporting rollers 32, and the supporting rollers 32 provide support for the chain plates in the up and down directions, so that the chain plates do not move in the up and down directions during the movement.

[0044] The arrangement of multiple support rollers 32 can provide stable support for the loading ring 3 and the cutting ring 4, so that the chain plates of the loading ring 3 and the cutting ring 4 have stable limiting support when they are located on both sides of the gap. When the chain plates squeeze the cloth in the accommodating cavity, the chain plates will not move in the up and down directions, providing a stable clamping force for the cloth in the accommodating cavity.

[0045] like Figure 9 and Figure 10 As shown, the cutting knife 41 is hinged to the cutting ring 4, and a limit block 42 is provided at the contact portion between the cutting knife 41 and the cutting ring 4 to limit the rotation angle of the cutting knife 41. A torsion spring with an elastic reset function is installed between the cutting knife 41 and the cutting ring 4. When the cutting knife 41 is subjected to the resistance of the fabric, it can rotate to the right around the hinge axis. In the natural state, the cutting knife 41 is against the limit block 42, and the cutting knife 41 is perpendicular to the chain plate of the cutting ring 4.

[0046] The hinge shaft is the rotating shaft connecting the cutting blade 41 to the cutting ring 4. Specifically, it can be implemented using a pin with a lubricating structure. This structure enables the cutting blade 41 to have adaptive rotation during operation. The torsion spring is an elastic element mounted on the outer periphery of the hinge shaft. Specifically, it can be implemented using a stainless steel coil spring. The torsion spring provides continuous rotational torque for the cutting blade 41. The limit block 42 is a mechanical limit structure provided at the end of the hinge shaft. Specifically, it can be implemented using a boss. This structure limits the rotation angle of the cutting blade 41 through physical contact.

[0047] Specifically, the cutting blade 41 is a movable component that pivots about a hinge. If the fabric cannot be completely cut in one go, the reaction force from the fabric pushes the cutting blade 41 to the right, automatically adjusting the cutting angle of the cutting edge to cut the fabric. A torsion spring accumulates elastic potential energy during the deflection of the cutting blade 41, and when the fabric resistance disappears, it rotates counterclockwise to its initial vertical position. A stopper 42 abuts the cutting blade 41, ensuring that the cutting blade 41 remains perpendicular to the cutting ring 4 at a 90-degree angle when in its natural position.

[0048] Traditional cutting devices use a rigid fixed blade structure, which is prone to jamming or incomplete cutting when encountering thicker fabrics. The rotatable cutting blade 41 structure is combined with an elastic reset mechanism to enable the cutting blade 41 to have the ability to adjust the cutting depth during the cutting process.

[0049] like Figures 4 to 7 As shown, a telescopic block 62 is provided on the side of the extrusion plate 31 facing the fabric, and the telescopic block 62 is provided between adjacent cutting seams 61. The telescopic block 62 can be retracted into the extrusion plate 31 along the left-right direction; a telescopic block 62 is provided on the side of the sliding plate 5 facing the fabric, and the telescopic block 62 is provided between adjacent cutting seams 61. The telescopic block 62 can be retracted into the sliding plate 5 along the left-right direction.

[0050] The telescopic block 62 is disposed on the surface of the extrusion plate 31 or the sliding plate 5. The telescopic block 62 can slide and adjust its displacement to compress the fabric in the accommodating cavity in the left-right direction. Specifically, the telescopic block 62 can be implemented as a block-shaped structure with a built-in elastic element. For example, a spring mechanism can be provided within the extrusion plate 31 to retract the telescopic block 62 into the extrusion plate 31 or the sliding plate 5 when compressed. The spaces between adjacent cutting slits 61 refer to the areas between the openings formed on the extrusion plate 31 or the sliding plate 5 by the cutting blade 41. Specifically, this can be implemented using a structure with equally spaced rectangular openings, such as a strip-shaped slit with a width 1.2-1.5 times the thickness of the cutting blade 41, formed on the plate surface.

[0051] Specifically, when the fabric enters the receiving chamber, the telescopic blocks 62 of the extrusion plate 31 and the sliding plate 5 are extended. The surfaces of the telescopic blocks 62 proximate to the extrusion plate 31 and the sliding plate 5 are coplanar with these two plates. As the cutting blade 41 performs its cutting action, the telescopic blocks 62 of the extrusion plate 31 retract into the plate body under the cutting pressure. At this point, the telescopic blocks 62 of the sliding plate 5 remain retracted, providing a counter-supporting force. At the cutting slit 61, an alternating compression pattern is formed between the extrusion plate 31 and the sliding plate 5 and the opposing telescopic blocks 62. The portion of the fabric in contact with the extrusion plate 31 and the sliding plate 5 forms a sequential arrangement of concave and convex surfaces, resulting in a localized compression of the fabric at the cutting slit 61. As the cutting ring 4 rotates, the cutting blade 41 cuts the fabric within the receiving chamber through the cutting slit 61. By squeezing the fabric within the receiving chamber into a sequential arrangement of concave and convex surfaces, the cut slit of the fabric is prevented from shifting during cutting.

[0052] The telescopic block 62 provides alternating pressure on the fabric within the chamber during the cutting process, maintaining stability while preventing movement and slit displacement. The variable chamber automatically releases the pressure after cutting is complete, allowing the cut fabric strips to separate naturally.

[0053] like Figure 2 and Figure 8 As shown, a sliding sleeve 73 is provided on the guide rod 71, and the end of the spring 72 away from the sliding plate 5 abuts against the sliding sleeve 73. The sliding sleeve 73 is an annular sleeve structure that can slide axially along the guide rod 71. Specifically, it can be positioned on the guide rod 71 by means of a threaded connection or a snap-fit locating method. The cooperation between the sliding sleeve 73 and the guide rod 71 is used to adjust the initial compression length of the spring 72. The initial elastic potential energy refers to the elastic deformation energy stored in the spring 72 when it is not subjected to an external load. Specifically, it is achieved by the sliding sleeve 73 changing the pre-compression of the spring 72. This pre-compression determines the initial pressing force of the sliding plate 5 on the fabric.

[0054] Specifically, as the sliding sleeve 73 moves axially along the guide rod 71, the end of the spring 72 away from the sliding plate 5 is restrained by the sliding sleeve 73. At this point, the effective compressed length of the spring 72 changes with the position of the sliding sleeve 73. To increase the pressure on the fabric, the sliding sleeve 73 moves toward the sliding plate 5, increasing the initial compression of the spring 72 and boosting its initial elastic potential energy. Conversely, as the sliding sleeve 73 moves away from the sliding plate 5, the compression of the spring 72 decreases, reducing its initial elastic potential energy. Thus, by adjusting the position of the sliding sleeve 73, the pressing force of the sliding plate 5 on the fabric can be adjusted, ensuring that the synergistic action of the cutting blade 41 and the squeezing plate 31 accommodates fabrics of varying thicknesses or materials.

[0055] Through the matching structure of the sliding sleeve 73 and the guide rod 71, the linear adjustment of the preload force of the spring 72 is achieved, which solves the problem in the prior art that the elastic potential energy cannot match the characteristics of the fabric. The initial pressing force of the elastic part 7 can be dynamically adjusted according to the thickness and hardness of the fabric, avoiding fabric displacement or incomplete cutting due to insufficient pressure during the cutting process.

[0056] like Figure 2 and Figure 3 As shown, the end of the feeding ring 3 near the feeding port protrudes beyond the cutting ring 4. Before cutting, the material is located on the upper end surface of the protruding end of the feeding ring 3. The protruding end of the feeding ring 3, i.e., the horizontal portion of the feeding ring 3 extending beyond the edge of the cutting ring 4 in the feeding direction, can be adjusted by adjusting the extension length of the chain plate structure so that the material, when entering, is located on the bearing surface formed by the protruding section of the feeding ring 3.

[0057] The cutting ring 4 rotates faster than the feeding ring 3. Specifically, the cloth is conveyed to the upper end surface of the protruding section of the feeding ring 3 during the feeding process. At this time, the cutting ring 4 does not contact the cloth. When the feeding ring 3 rotates, the cloth is continuously conveyed to the gap formed by the feeding ring 3 and the cutting ring 4 as the chain plate moves. Since the cutting knife 41 on the cutting ring 4 is located on the outer surface of the cutting ring 4, before the cloth moves to the gap area between the cutting ring 4 and the feeding ring 3, the cutting knife 41 moves from the opening of the gap into the gap, and the cutting knife 41 pushes the cloth on the protruding end into the gap. When the cloth moves to the right side of the sliding plate 5, the cloth causes the cutting knife 41 to rotate to the right and pass over the cloth. The multiple cutting knives 41 arranged at equal intervals along the circumference of the cutting ring 4 sequentially push the cloth into the gap until the extrusion plate 31 moves to the gap.

[0058] By setting the side of the feeding ring 3 close to the feeding end to protrude from the cutting ring 4, and making the cutting ring 4 rotate faster than the feeding ring 3, the cutting knife 41 continuously pushes the material into the accommodating cavity, preventing the cloth from accumulating at the entrance of the gap and being unable to enter the gap normally.

[0059] like Figure 2 and Figure 3 As shown, the end of the cutting ring 4 near the discharge opening protrudes beyond the loading ring 3. This end of the cutting ring 4 near the discharge opening extends beyond the edge of the loading ring 3 in the longitudinal direction. This can be achieved, for example, by extending the length of the cutting ring 4's circumferential chain plate or adjusting the mounting position. The discharge opening is the channel for discharging the cut fabric strips after cutting. Specifically, it is an opening on the left side of the mounting cavity 2. A conveyor is provided at the lower end of the discharge opening to transport the cut fabric strips away to prevent accumulation and blockage of the discharge opening.

[0060] After the material discharging port is opened, the material discharging ring 31 of the upper and lower parts of the material discharging port is opened, and the material discharging ring 31 of the upper and lower parts of the material discharging port is opened.

[0061] The cutting ring 4 and feeding ring 3 are arranged in a staggered arrangement, allowing the cut material to be quickly and precisely removed from the cutting area. This prevents residual fibers from entangled with the cutting blade 41 or blocking the discharge port, ensuring stable operation during continuous operation while reducing the frequency of manual cleaning of residual fabric. The dynamic support of the chain plate structure and the coordinated clamping action of the extrusion plate 31 and the sliding plate 5 eliminate fabric displacement during cutting. The articulated design of the cutting blade 41, coordinated with the chain plate's trajectory, ensures that the cutting angle of the cutting blade 41 matches the cutting state of the fabric in real time, effectively preventing fabric entanglement with the cutting blade 41 or incomplete cutting. This is particularly suitable for the continuous cutting of large pieces of flexible fabric.

[0062] like Figure 6 and Figure 7 As shown, the telescopic block 62 on the sliding plate 5 is tilted, tilting leftward from top to bottom. The tilted telescopic block 62 forms a certain angle with the horizontal plane, and the direction of cloth movement is controlled by adjusting the tilt angle. The leftward tilt from top to bottom refers to the top of the telescopic block 62 being offset to the right. This can be achieved by using a hinged structure in conjunction with a limit slot to maintain a stable tilted surface during the cloth cutting process.

[0063] Specifically, when the cut fabric moves with the sliding plate 5 to the opening of the receiving chamber, the inclined surface of the telescopic block 62 forms a downwardly sloping guide surface. Gravity forces the fabric to slide along the inclined surface toward the lower left, while the tilted force of the telescopic block 62 simultaneously pushes the fabric away from the cutting area. By redirecting the force acting on the fabric through the tilted structure, the dual effects of gravity and thrust enable rapid material discharge, eliminating manual cleaning or secondary processing.

[0064] The tilted telescopic block 62 solves the problem of poor material discharge after cutting. The tilted telescopic block 62 guides the material out of the cutting area in a specific direction, effectively reducing residual material, improving the efficiency of continuous cutting operations, and reducing the risk of equipment failure due to blockage.

[0065] like Figures 4 to 7 As shown, multiple rollers 63 are set on the inclined surface of the telescopic block 62. The multiple rollers 63 are set on the surface of the inclined telescopic block 62 along the up and down directions. The rollers 63 are set along the front and back directions, and the rollers 63 rotate around their axes in the front and back directions.

[0066] The rollers 63 are cylindrical components that rotate about their axes. Specifically, they can be implemented using a combination of bearings and metal sleeves. When their outer surfaces come into contact with the fabric, rolling friction is generated. A forward-backward arrangement means that the axis of the rollers 63 is perpendicular to the left-right conveying direction of the device, ensuring that the fabric's movement aligns with the direction of rotation of the rollers 63. A vertical arrangement means that the rollers 63 are distributed longitudinally along the surface of the inclined block, forming a continuous rolling contact surface. For example, each roller 63 is evenly spaced and fixed to the surface of the inclined telescopic block 62. This arrangement creates uniform rolling support at different heights of the inclined telescopic block 62, preventing excessive friction from locally exerting pressure on the fabric and hindering its rapid discharge.

[0067] Specifically, as the cut fabric moves downward along the inclined telescopic block 62, it contacts the rollers 63, generating rolling friction. The rollers 63 are arranged in a forward-backward direction so that their rotational axis is perpendicular to the fabric's direction of movement. As the fabric moves up and down, they rotate about their axis. The vertical arrangement of the rollers 63 forms a continuous rolling path, and gravity forces the fabric to continuously roll down the surfaces of the rollers 63. When the fabric is subjected to the interaction force between the squeeze plate 31 and the cutting ring 4, the rotation of the rollers 63 effectively offsets the sliding friction between the fabric and the inclined telescopic block 62.

[0068] By arranging multiple sets of directional rollers 63 on the inclined surface of the telescopic block 62, sliding friction is converted into rolling friction, allowing the fabric to quickly escape the gap after cutting. This structure is particularly effective for waste fabrics with loose fibers or rough surfaces, preventing fibers from catching on the inclined surface of the telescopic block 62 and causing discharge blockage.

[0069] Through the above technical solution, the present invention effectively reduces the frictional resistance between the fabric and the inclined block, solving the problem of poor fabric discharge after cutting. Supported by rollers 63, the fabric slides smoothly along the inclined surface of telescopic block 62, avoiding movement delays or localized accumulation caused by friction, thereby improving the continuity of the cutting process and the efficiency of fabric discharge.

[0070] Preferably, multiple groups of cutting blades 41 are arranged at equal intervals on the cutting ring 4 , and the multiple groups of cutting blades 41 are arranged at equal intervals on the outer surface of the cutting ring 4 . The cutting efficiency can be improved by increasing the number of cutting blades 41 .

[0071] Working principle: the feeding ring 3 rotates counterclockwise, and the cutting ring 4 rotates clockwise. The cloth to be cut is placed on the protruding section of the feeding ring 3. The cloth on the feeding ring 3 moves to the entrance of the gap between the feeding ring 3 and the cutting ring 4 as the feeding ring 3 rotates. When the cutting ring 4 rotates, the cutting ring 4 rotates faster than the feeding ring 3. The multiple groups of cutting knives 41 provided on the cutting ring 4 push the cloth at the entrance of the gap on the feeding ring 3 into the gap. When the cloth moves to the right side of the sliding plate 5, the cloth blocks the cutting knives 41 so that The cutting knife 41 rotates to the right and passes over the cloth. When the cloth in the gap accumulates to the entrance, the feeding stops, and the feeding ring 3 drives the squeezing plate 31 to move into the gap. The feeding ring 3, the cutting ring 4, the squeezing plate 31 and the sliding plate 5 form a dynamic accommodating chamber. The squeezing plate 31 continues to move to the left to squeeze the cloth and push the sliding plate 5. The spring 72 on the left side of the sliding plate 5 limits the movement of the sliding plate 5 and makes the sliding plate 5 exert a rightward reaction force on the cloth. The sliding plate 5 and the squeezing plate 31 squeeze the cloth in the accommodating chamber.

[0072] In the cutting state, the telescopic blocks 62 provided on the extrusion plate 31 and the sliding plate 5 are squeezed by the cloth and retract into the extrusion plate 31 and the sliding plate 5, so that the end surfaces of the cloth in contact with the extrusion plate 31 and the sliding plate 5 are arranged in a concave and convex shape, thereby restricting the movement of the cloth in the accommodating cavity. The cutting blade 41 enters the accommodating cavity through the cutting slit 61 to cut the cloth.

[0073] While the cloth in the accommodating cavity is being cut by the cutting knife 41, the squeezing plate 31 continues to move to the left. When the sliding plate 5 compresses the cloth on the left, the pressure on the cloth in the accommodating cavity gradually increases, so that the cloth in the accommodating cavity does not move.

[0074] After the cloth cutting is completed, the sliding plate 5 is disengaged from the feeding ring 3, and the cloth abutting the supporting wheel inclined by the sliding plate 5 is discharged from the opening between the sliding plate 5 and the feeding ring 3 under the action of gravity and the downward component of the squeezing force of the inclined telescopic block 62. When all the material is discharged, the squeezing plate 31 abuts on the sliding plate 5, and the squeezing plate 31 rotates to the left to pass over the sliding plate 5. The sliding plate 5 is reset under the action of the spring 72, completing one cut.

[0075] Although the embodiments of the present invention have been shown and described above, it will be understood that the above embodiments are illustrative and are not to be construed as limitations on the present invention. A person skilled in the art may change, modify, replace and modify the above embodiments within the scope of the present invention.
