Description

Technical Field

[0001] This invention relates to the field of yarn waste treatment technology, and in particular to a yarn production waste recycling and shredding equipment. Background Technology

[0002] The yarn production process generates a large amount of waste. If this waste is discarded directly, it will not only waste resources but also cause environmental pollution. Shredding is the core pre-process for waste recycling. Yarn waste is elastic, fluffy, and easy to tangle, which leads to a prominent problem of yarn entanglement on the cutter shaft in existing shredding equipment. This has become a key bottleneck restricting the efficient operation of the equipment.

[0003] Currently, most existing yarn waste shredding equipment adopts a traditional single-shaft or double-shaft shredding structure. However, it lacks a specific anti-tangling structure to address the problem of yarn easily tangling around the blade shaft, resulting in the following main drawbacks: First, the blades of traditional equipment are mostly fixed and exposed. During shredding, yarn waste easily gets tangled on the blade shaft surface and in the gaps between the blades, causing equipment downtime and requiring manual cleaning, severely impacting processing efficiency and increasing labor costs. Second, although some equipment has an anti-stick coating on the blade shaft surface, this only alleviates minor tangling and cannot solve the core problem of yarn embedding in the blade gaps and tangling around the blade shaft. Third, the lack of an active cleaning structure allows the tangled yarn to accumulate, not only affecting the shredding effect but also increasing the load on the blade shaft and shortening the equipment's lifespan. Therefore, there is an urgent need to design a yarn production waste recycling and reuse shredding equipment to solve these problems. Summary of the Invention

A central shaft is fixedly mounted between the two drive shafts. A transmission plate, evenly spaced and arranged in a ring, is fixed to the outer wall of the central shaft. One end of each transmission plate is fixed to the same rotating drum. The rotating drum has evenly spaced inlets and outlets located on one side of the transmission plate. The number of inlets and outlets is the same as the number of transmission plates. Cutters are inserted into the inner walls of each inlet and outlet, and the bottom of each cutter is attached to the conveyor belt. An adjusting groove is provided on one side of each of the two adjusting discs. Adjusting wheels are rotatably connected to both ends of each cutter via pins. The adjusting wheels are rolled within the corresponding adjusting grooves. Each adjusting groove consists of an outer ring, an inner ring, and two arc-shaped corner sections. The two ends of the arc-shaped corner sections are smoothly connected to the ends of the outer ring and the inner ring, respectively.

[0008] The invention is further configured such that each of the transmission plates has a plurality of guide grooves corresponding to the cutter, and the side wall of the cutter is fixedly connected to a guide sleeve block that is slidably disposed in the guide groove. The inner wall of the guide groove is fixed with a guide rod that passes through the guide sleeve block, and the outer wall of the guide rod is fitted with a second spring, and the two ends of the second spring are fixedly connected to one side of the guide sleeve block and one side of the guide groove, respectively.

[0009] The present invention is further configured such that the cleaning assembly includes a cleaning seat, one side of which is in contact with the surface of the rotating drum, and an mounting plate is fixedly installed on the other side of the top inner wall of the housing. The bottom of one side of the mounting plate is hinged to the top of the cleaning seat, and a plurality of third springs are fixedly installed on one side of the mounting plate and the top of the cleaning seat.

[0010] The present invention is further configured such that the driving mechanism includes a shredding motor, and the shredding motor is fixedly mounted on the outer side wall of the housing by a mounting bracket. The output shaft of the shredding motor is fixedly connected to the end of one of the driving shafts. A transmission wheel is fixedly mounted on one end of both the output shaft of the shredding motor and the transmission shaft, and a transmission belt is connected between the two transmission wheels.

[0011] The invention is further configured such that a support plate is fixedly connected to the inner wall of the housing, and the top of the support plate is in contact with the inner conveying surface of the conveyor belt, and the support plate is located directly below the shredding assembly.

[0012] The present invention is further configured such that a discharge port is provided at the bottom of the end of the housing away from the feed port, and an inclined discharge frame is fixedly installed on the inner wall of the discharge port. A scraper seat is fixedly connected to the inner side wall of the discharge frame, and the top of the scraper seat is in contact with the conveying surface of the conveyor belt.

[0013] The present invention is further configured such that a support frame is fixedly installed at the bottom of the housing, and brake casters are fixedly installed at the four corners of the bottom of the support frame; a controller is fixedly installed on the outer wall of the housing, and the controller is electrically connected to the conveying motor and the shredding motor.

[0014] In summary, by adopting the above structure, the present invention has the following advantages compared with the prior art: 1. In this invention, through the cooperation of the partition plate, arc plate, L-shaped pressure plate, cam, first spring and L-shaped fixing plate in the pretreatment component, the blade-like structure of the partition plate is used to evenly divert and comb the fluffy yarn waste fed from the feed port, dividing the clumps of waste into several independent areas. The arc plate assists in the smooth transport of the waste to the conveyor belt. At the same time, the cam rotates with the drive shaft to squeeze the L-shaped pressure plate, causing the L-shaped pressure plate to move up and down along the guide column and guide hole. The first spring realizes the rapid reset of the L-shaped pressure plate, repeatedly squeezing and compacting the waste in each area, effectively reducing the fluffiness and fiber interlacing density of the waste. From the source of feeding, the probability of yarn tangling and accumulating due to fluffiness will be reduced and will not be able to wrap around the subsequent shredding components, ensuring the continuity of the shredding operation and avoiding equipment downtime due to feeding blockage or tangling.

[0015] 2. In this invention, through the cooperation of the rotating drum, cutter, adjusting disc, adjusting wheel, guide sleeve, guide rod, and second spring in the shredding assembly, the trajectory changes of the outer ring, inner ring, and arc-shaped corner of the adjusting groove on the adjusting disc drive the adjusting wheels at both ends of the cutter to rotate synchronously with the rotating drum. This drives the cutter to extend and retract along the guide groove and guide rod of the transmission plate. The second spring helps to achieve precise resetting of the cutter, so that when the cutter rotates above the conveyor belt, it extends from the inlet and outlet of the rotating drum to efficiently shear the compacted waste material. After shredding, it quickly retracts into the rotating drum as it rotates, completely avoiding continuous contact between the exposed cutter and the yarn fibers. Structurally, this eliminates the core problem of yarn entanglement on the cutter shaft, cutter, and rotating drum inlet and outlet, significantly improving shredding efficiency while ensuring the uniformity of the particle size of the shredded material.

[0016] 3. In this invention, the cleaning seat, mounting plate, and third spring in the cleaning assembly work together to ensure that the cleaning seat is always in close contact with the surface of the rotating drum. During the rotation of the drum and the retraction of the cutter into the drum, residual yarn fibers on the surface of the drum, the edges of the inlet and outlet, and the gap between the cutters can be scraped off in real time. After the cutter extends, the yarn remaining in the inlet and outlet can be pushed out, forming a synchronous linkage mechanism for chopping and cleaning. There is no need for manual disassembly and cleaning, which not only significantly reduces the intensity of manual labor and labor costs, but also avoids problems such as increased load on the cutter shaft and accelerated wear of the equipment caused by the accumulation of tangled yarn. This effectively extends the service life of the equipment and improves the stability and reliability of the equipment operation.

[0017] 4. In this invention, the shredding motor, transmission belt, transmission shaft and drive shaft in the drive mechanism are coordinated to achieve synchronous driving of the pretreatment component and the shredding component, so that the waste diversion and compaction and the rotation shredding rhythm are highly matched, avoiding waste accumulation or insufficient shredding caused by asynchronous operation of the two; at the same time, the stable conveying of the conveyor belt, the support plate supporting the conveyor belt, and the scraper seat scraping the residual waste on the surface of the conveyor belt ensure the high efficiency and stability of the shredding operation, and improve the recycling quality of yarn waste.

[0023] Please see Figures 1-12 This invention provides a yarn production waste recycling and shredding device, comprising: The machine housing 1 has a feed inlet 2 at one top end and a waste conveying assembly inside. The waste conveying assembly includes conveying rollers 12 rotatably connected to both ends of the inner wall of the machine housing 1, and a conveyor belt 13 is driven between the conveying rollers 12. A conveyor motor 4 is fixedly installed on one outer wall of the machine housing 1. The output shaft of the conveyor motor 4 is fixedly connected to the end of one of the conveying rollers 12 to drive the conveying roller 12 to rotate. The top surface of the conveyor belt 13 is attached to the bottom outlet of the feed inlet 2. The conveyor motor 4 drives the conveying rollers 12 to rotate, which in turn drives the conveyor belt 13 to rotate, so as to realize the smooth reception and conveying of yarn waste from the feed inlet 2, providing stable material conveying support for subsequent processes. At the same time, the conveyor belt 13 is attached to the bottom of the feed inlet 2 to prevent waste from falling, ensuring the continuity of feeding and conveying, and improving the overall operating efficiency of the equipment. The pretreatment component 9 is located on one side of the feed inlet 2, and its bottom is in contact with the conveying surface of the waste conveying component. The pretreatment component 9 includes several partition plates 91 that are fixedly installed at equal intervals at the bottom discharge end of the feed inlet 2. The end of the partition plate 91 near the feed inlet 2 has a blade-like structure, and the end of the partition plate 91 away from the feed inlet 2 is fixedly connected to an arc-shaped plate 92. The bottom of the arc-shaped plate 92 and the partition plate 91 are in contact with the top surface of the conveyor belt 13. An L-shaped pressure plate 96 is movably attached between two adjacent partition plates 91 and arc-shaped plates 92. An L-shaped fixing plate 95 is fixedly installed on one side of the top inner wall of the housing 1. The bottom of the L-shaped fixing plate 95 has guide holes that correspond one-to-one with the L-shaped pressure plate 96. A guide post 98 passing through the guide hole is fixedly connected to one side of the top of the L-shaped pressure plate 96, and the cross-section of the guide post 98 is T-shaped. A first spring 97 is sleeved on the outer wall of the guide post 98, and the two ends of the first spring 97 are fixedly connected to the top of the guide post 98 and the bottom of the L-shaped fixing plate 95, respectively. A drive shaft 93 is rotatably connected to the housing 1 through a bearing, and a cam 94 corresponding to the L-shaped pressure plate 96 is fixedly installed on the outer wall of the drive shaft 93. The outer wall of the cam 94 is in contact with the top of the corresponding L-shaped pressure plate 96, which is used to drive the L-shaped pressure plate 96 to move up and down in the vertical direction. The drive shaft 93 drives the cam 94 to rotate, squeezing the L-shaped pressure plate 96 to move up and down along the guide post 98 and the guide hole. The first spring 97 assists in resetting. With the diversion of the separator plate 91 and the smooth conveying of the arc plate 92, the fluffy yarn waste is diverted and repeatedly compacted to break the fiber intertwining state, reduce the risk of yarn entanglement from the source, and at the same time ensure that the waste is evenly conveyed to the shredding component 10, laying the foundation for subsequent shredding operations. The chopping assembly 10 is installed inside the housing 1 and is located on the side of the pretreatment assembly 9 away from the feed inlet 2. The chopping assembly 10 includes first mounting holes 101 on both sides of the housing 1, and adjusting discs 102 are fixedly installed on the inner walls of the first mounting holes 101. A second mounting hole 1015 is opened in the middle of the two adjusting discs 102. The inner walls of the second mounting holes 1015 are rotatably connected to drive shafts 103 through bearings. The two drive shafts 1015... A central shaft 107 is fixedly installed between points 3. A transmission plate 106, evenly spaced and arranged in a ring, is fixed to the outer wall of the central shaft 107. One end of each transmission plate 106 is fixed to a rotating drum 104. The rotating drum 104 has evenly spaced inlets and outlets 1013, located on one side of the transmission plate 106. The number of inlets and outlets 1013 is the same as the number of transmission plates 106. Cutters 105 are inserted into the inner walls of each inlet and outlet 1013, and the bottom of each cutter 105... The cutter 105 is attached to the conveyor belt 13. Each of the two adjusting discs 102 has an adjusting groove 108 on one side. Both ends of the cutter 105 are rotatably connected to adjusting wheels 1014 via pins. The adjusting wheels 1014 are rolled within the corresponding adjusting grooves 108. Each adjusting groove 108 consists of an outer ring 1081, an inner ring 1082, and two arc-shaped corner sections 1083. The two ends of the arc-shaped corner sections 1083 are smoothly connected to the ends of the outer ring 1081 and the inner ring 1082, respectively. The drive shaft... 103 drives the central shaft 107, transmission plate 106 and rotating drum 104 to rotate. When the cutter 105 rotates with the rotating drum 104, the adjusting wheel 1014 rolls along the outer ring 1081, inner ring 1082 and arc corner 1083 of the adjusting groove 108, which drives the cutter 105 to achieve telescopic movement, realizing efficient shearing of pre-treated waste. The telescopic structure of the cutter 105 can prevent it from getting tangled in yarn when it is exposed, while ensuring that the particle size of the shredded material is uniform and improving the quality of waste recycling. The drive mechanism is installed on one side of the housing 1 and is used to drive the pretreatment component 9 and the shredding component 10 to work synchronously. The drive mechanism includes a shredding motor 7, which is fixedly installed on the outer side wall of the housing 1 by a mounting bracket. The output shaft of the shredding motor 7 is fixedly connected to the end of one of the drive shafts 103. A transmission wheel is fixedly installed on one end of the output shaft of the shredding motor 7 and the transmission shaft 93. A transmission belt 6 is connected between the two transmission wheels. The shredding motor 7 drives the drive shaft 103 to rotate through the output shaft, and at the same time drives the transmission shaft 93 to rotate synchronously through the transmission belt 6, so as to realize the coordinated linkage between the pretreatment component 9 and the shredding component 10 and ensure that the waste pretreatment and shredding rhythm are matched. The cleaning component 11 is installed inside the housing 1 and is located on the side of the shredding component 10 away from the pretreatment component 9. The cleaning component 11 includes a cleaning seat 111, one side of which is in contact with the surface of the rotating drum 104. A mounting plate 112 is fixedly installed on the other side of the top inner wall of the housing 1. The bottom of one side of the mounting plate 112 is hinged to the top of the cleaning seat 111. A plurality of third springs 113 are fixedly installed on one side of the mounting plate 112 and the top of the cleaning seat 111. The third springs 113 provide elastic support so that the cleaning seat 111 is always in close contact with the surface of the rotating drum 104. When the rotating drum 104 rotates, the cleaning seat 111 scrapes away the residual yarn fibers on the surface of the rotating drum 104 and at the inlet and outlet 1013 in real time, avoiding yarn entanglement and accumulation. There is no need for manual shutdown for cleaning, thus reducing labor costs.

[0024] In this invention, the transmission plate 106 is provided with a plurality of guide grooves 109 corresponding one-to-one with the cutter 105, and the side wall of the cutter 105 is fixedly connected to a guide sleeve block 1010 which is slidably disposed in the guide groove 109. The inner wall of the guide groove 109 is fixedly provided with a guide rod 1011 that passes through the guide sleeve block 1010. The outer wall of the guide rod 1011 is fitted with a second spring 1012, and the two ends of the second spring 1012 are fixedly connected to one side of the guide sleeve block 1010 and one side of the guide groove 109, respectively. When the cutter 105 performs telescopic movement, the guide sleeve block 1010 slides along the guide groove 109 and the guide rod 1011, and the second spring 1012 assists the cutter 105 to quickly return to its original position, ensuring that the telescopic movement of the cutter 105 is accurate and stable, avoiding uneven chopping or yarn entanglement caused by the deviation of the cutter 105, while improving the service life of the cutter 105 and ensuring stable chopping operation.

[0025] In this invention, a support plate 14 is fixedly connected to the inner wall of the housing 1, and the top of the support plate 14 is in contact with the inner conveying surface of the conveyor belt 13. The support plate 14 is located directly below the chopping assembly 10. During the chopping operation, the support plate 14 provides stable support for the conveyor belt 13 to prevent the conveyor belt 13 from being dented due to the shearing force of the cutter 105.

[0026] In this invention, the bottom of the end of the housing 1 away from the feed inlet 2 is provided with a discharge port, and an inclined discharge frame 8 is fixedly installed on the inner wall of the discharge port. A scraper seat 15 is fixedly connected to the inner side wall of the discharge frame 8, and the top of the scraper seat 15 is in contact with the conveying surface of the conveyor belt 13. Both the scraper seat 15 and the cleaning seat 111 are made of rubber. The shredded waste is conveyed to the discharge end with the conveyor belt 13. The scraper seat 15 scrapes the waste remaining on the surface of the conveyor belt 13 and scrapes it off to the discharge frame 8, avoiding yarn entanglement or waste caused by the accumulation of waste residue.

[0027] In this invention, a support frame 5 is fixedly installed at the bottom of the housing 1, and brake casters are fixedly installed at the four corners of the bottom of the support frame 5. A controller 3 is fixedly installed on the outer wall of the housing 1, and the controller 3 is electrically connected to the conveying motor 4 and the shredding motor 7. The support frame 5 provides stable support for the entire equipment, and the brake casters enable flexible movement and fixation of the equipment to adapt to different operating scenarios. The controller 3 enables coordinated control of the conveying motor 4 and the shredding motor 7, which facilitates operation by the staff.

[0028] In summary, the working principle of this invention is as follows: During operation, the operator starts the conveyor motor 4 and the shredding motor 7 through the controller 3. The conveyor motor 4 drives the conveyor roller 12 to rotate, which in turn drives the conveyor belt 13 to operate. The yarn production waste is fed into the feed inlet 2. The conveyor belt 13 transports the waste to the pretreatment component 9. The separator plate 91 at the bottom of the feed inlet 2 first diverts the waste. The arc plate 92 at the end of the separator plate 91 away from the feed inlet 2 assists in the smooth transport of the waste. At the same time, the shredding motor 7 drives the transmission shaft 93 to rotate through the transmission belt 6. The cam 94 on the transmission shaft 93 rotates synchronously. The cam 94 squeezes the L-shaped pressure plate 96, causing the L-shaped pressure plate 96 to move up and down along the guide hole and guide post 98 of the L-shaped fixed plate 95. The first spring 97 cooperates to realize the reset of the L-shaped pressure plate 96, and repeatedly squeezes and compacts the waste between the two adjacent separator plates 91 to avoid the waste from being loose and causing it to entangle during subsequent shredding. The compacted waste material is conveyed to the shredding assembly 10 by the conveyor belt 13. The shredding motor 7 drives the drive shaft 103 to rotate, which in turn drives the central shaft 107 and the transmission plate 106 to rotate, thereby driving the rotating drum 104 to rotate synchronously. The cutter 105 on the rotating drum 104 rotates with the rotating drum 104. The adjusting wheels 1014 at both ends of the cutter 105 roll in the adjusting groove 108 of the adjusting plate 102. The outer ring 1081, inner ring 1082 and arc-shaped corner of the adjusting groove 108 are connected. Part 1083 drives the adjusting wheel 1014 to move, which in turn drives the cutter 105 to extend and retract along the guide groove 109 and guide rod 1011 of the transmission plate 106. The second spring 1012 cooperates to reset the cutter 105, so that when the cutter 105 extends from the inlet and outlet 1013 of the drum 104, it cuts the waste on the conveyor belt 13. When it retracts, it avoids yarn tangling. The support plate 14 on the inner wall of the machine housing 1 supports the conveyor belt 13 to ensure the cutting effect. During the shredding process, the cleaning seat 111 of the cleaning component 11 is always in contact with the surface of the rotating drum 104 under the elastic force of the third spring 113, and cleans the yarn that may be entangled on the surface of the rotating drum 104 and at the inlet and outlet 1013 in real time. The shredded waste continues to be conveyed with the conveyor belt 13. The scraper seat 15 on the inside of the discharge frame 8 scrapes off the waste remaining on the surface of the conveyor belt 13. Finally, the waste is discharged from the discharge frame 8, completing the entire shredding and recycling process. The brake casters at the bottom of the support frame 5 can realize the flexible movement and fixation of the equipment. The entire process is controlled by the controller 3 to achieve coordinated control of each motor, ensuring stable and efficient operation of the equipment.

[0029] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this invention.
