Description

Technical Field

[0001] This invention relates to the field of fabric crushing technology, specifically to a lining fabric recycling and crushing processing device. Background Technology

[0002] Lining is a lightweight fabric commonly used in linings, underwear, and waterproof clothing. During garment production using lining, scraps and unsuitable fabric are generated due to cutting and sewing processes. To improve waste fabric recycling efficiency and facilitate subsequent processing and resource utilization, crushing equipment is used to process the waste fabric.

[0003] One existing type of lining waste recycling equipment on the market has two rows of blades installed in a fixed funnel. The two rows of blades are fixedly installed on the output shaft. Through the relative movement of the two rows of blades, the waste fabric can be shredded. However, during the shredding process of the waste fabric, due to the extensibility of the fabric, it is easy for the fabric to be pulled and wrapped around the blade shaft during the cutting or crushing process, causing the machine to jam. Furthermore, when cleaning the waste fabric wrapped around the blade shaft manually, the small spacing between the blades makes it easy for personnel to be cut by the blades, and there are many dead corners, making it difficult to clean thoroughly. Summary of the Invention

[0010] Preferably, a limiting groove is formed on the hollow cutter shaft corresponding to the cutting blade, and the cutting blade can move left and right inside the hollow cutter shaft through the limiting groove. Through grooves are formed on the connecting ring, the crushing blade, and the positioning seat corresponding to the cutting blade, and the through grooves are used for the cutting blade to pass through the connecting ring, the cutting blade, and the positioning seat.

[0012] Preferably, two symmetrically distributed positioning rings are movably sleeved on the outer side of the hollow cutter shaft, and the two positioning rings are respectively located at two positioning seats at opposite ends. An avoidance groove is provided on the outer side of the positioning ring corresponding to the cutting blade.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention utilizes a cutting mechanism and an anti-winding component. During the process of the hollow blade shaft in the cutting mechanism driving the crushing blade to cut and crush the recycled lining, the moving seat can be rotated by the limiting slide rod and the slider. The moving seat rotates outside the reciprocating screw, which can drive multiple cutting blades to move back and forth. During the movement, the cutting blades can perform transverse cutting on the lining that falls on the hollow blade shaft, thereby preventing the lining from getting tangled on the hollow blade shaft and causing the machine to jam. There is no need for personnel to clean the lining that is tangled on the hollow blade shaft later.

[0016] 2. By installing an anti-blocking mechanism, the air pump in the anti-blocking mechanism blows air into the hollow cutter shaft through a bent air pipe during the rotation of the cutter shaft. The gas inside the hollow cutter shaft is discharged through the limiting straight groove, thereby preventing impurities such as lining fibers from entering the hollow cutter shaft through the limiting straight groove and preventing the lining fibers or impurities from clogging the hollow cutter shaft.

[0017] 3. By installing a grinding component, the cutting blade moves back and forth, and under the compression force of the spring, both sides of the cutting blade will come into contact with and rub against the grinding stone, thereby enhancing the sharpness of the cutting blade and making the cutting blade smoother when cutting the recycled lining fabric laterally.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1: Please refer to Figures 1-4 , Figure 6 The diagram shows a lining recycling and crushing equipment, including a crushing box 1, a hopper 2 fixedly installed inside the crushing box 1, and a crushing mechanism for crushing the recycled lining. The crushing mechanism is installed inside the crushing box 1 and located below the hopper 2. An anti-winding component is installed inside the crushing mechanism to prevent waste lining from winding around the crushing mechanism and causing it to jam. An anti-winding component is installed at the right end of the anti-winding component to prevent lining fibers from clogging the crushing mechanism. A grinding component is installed on the crushing mechanism to grind the anti-winding component.

[0022] The crushing mechanism includes two hollow cutter shafts 3 that are rotatably mounted inside the crushing box 1 via bearings, and the two hollow cutter shafts 3 are symmetrically distributed. A motor 4 is fixedly connected to the left end of one of the hollow cutter shafts 3, and the connection between the motor 4 and the crushing box 1 is fixed. Gears 5 are fixedly sleeved on the outer sides of both hollow cutter shafts 3, and the connection between the two gears 5 is meshing. The two gears 5 are used to make the two hollow cutter shafts 3 rotate in opposite directions.

[0023] Two gears 5 are close to the left side wall of the crushing box 1. Multiple circumferentially distributed limiting ribs 6 are fixedly provided on the outer side of the hollow cutter shaft 3. Multiple circumferentially distributed connecting rings 7 are movably sleeved on the outer side of the hollow cutter shaft 3 and the limiting ribs 6. Crushing blades 8 are fixedly sleeved on the outer side of the connecting rings 7, and the crushing blades 8 on the outer side of the two hollow cutter shafts 3 are staggered. The limiting ribs 6 are used to drive the multiple crushing blades 8 to rotate. Positioning seats 9 are fixedly connected to the outer side of the connecting rings 7 at both ends, and the positioning seats 9 are movably sleeved on the outer side of the hollow cutter shaft 3 and the limiting ribs 6.

[0024] Multiple fixing screws 10 are movably embedded on the outer side of the positioning seat 9, and the connection between the fixing screws 10 and the hollow cutter shaft 3 is a threaded connection. Two symmetrically distributed support seats 11 are fixedly installed on the inner right side of the crushing box 1, and the hollow cutter shaft 3 is rotatably connected to the support seats 11 through bearings. The outer sides of the two gears 5 are movably fitted with covers 30, and the connection between the covers 30 and the crushing box 1 is a fixed connection. The hollow cutter shaft 3 passes through the covers 30, and the covers 30 are used to prevent the lining or lining limiter from getting stuck between the two gears 5.

[0025] The anti-winding component includes a reciprocating screw 12 installed inside the hollow cutter shaft 3, and the left end of the reciprocating screw 12 is rotatably connected to the hollow cutter shaft 3 through a bearing. The reciprocating screw 12 is rotatably connected to the right side wall of the crushing box 1. A movable seat 13 is installed on the outside of the reciprocating screw 12. Multiple cutter holders 14 are fixedly installed on the outside of the movable seat 13 in a circumferentially equidistant manner. A cutting blade 15 is fixedly embedded at the end of the cutter holder 14 away from the movable seat 13. The cross-sectional shape of the cutting blade 15 is an equilateral triangle.

[0026] A limiting groove is provided on the hollow cutter shaft 3 corresponding to the cutting blade 15, and the cutting blade 15 can move left and right inside the hollow cutter shaft 3 through the limiting groove. A through groove is provided on the connecting ring 7, the crushing blade 8 and the positioning seat 9 corresponding to the cutting blade 15. The through groove is used for the cutting blade 15 to pass through the connecting ring 7, the crushing blade 8 and the positioning seat 9. Two symmetrically distributed sliders 16 are also fixedly installed on the outside of the moving seat 13. Two symmetrically distributed limiting slide rods 17 are fixedly installed inside the hollow cutter shaft 3, and the sliders 16 are movably sleeved on the outside of the limiting slide rods 17.

[0027] Working principle: When in use, the personnel put the recycled lining into the hopper 2 inside the crushing box 1. The motor 4 drives one of the hollow cutter shafts 3 to rotate. Under the action of the two gears 5, the two hollow cutter shafts 3 rotate in opposite directions, driving the two rows of staggered crushing blades 8 to rotate in the opposite direction to crush the recycled lining. During the rotation of the hollow cutter shaft 3, due to the self-locking performance of the motor 33, the reciprocating screw 12 does not rotate with the hollow cutter shaft 3. Since the slider 16 is movably sleeved on the outside of the limiting slide bar 17, the hollow cutter shaft 3 drives the moving seat 13 to rotate outside the reciprocating screw 12 through the limiting slide bar 17 and the slider 16. During this process, the moving seat 13 and the cutting blade 15 can move back and forth inside the hollow cutter shaft 3, so that the cutting blade 15 can perform transverse cutting on the lining cloth falling on the hollow cutter shaft 3, thereby avoiding the lining cloth from getting tangled on the hollow cutter shaft 3 and causing jamming. When the lining cloth becomes entangled on the hollow cutter shaft 3 at a distance from the cutting blade 15, the hollow cutter shaft 3 cannot rotate due to the entanglement of the lining cloth. Therefore, the motor 2 33 runs and drives the reciprocating screw 12 to rotate through the gear 2 32 and the gear ring 31. The rotation of the reciprocating screw 12 drives the moving seat 13 and the cutting blade 15 to move and cut the lining cloth entangled on the outside of the hollow cutter shaft 3. There is no need for personnel to clean the lining cloth entangled on the hollow cutter shaft 3 later.

[0028] Example 2: Please refer to Figure 5 , Figure 7 This embodiment further explains Example 1. The anti-blocking component includes an air pump 18 fixedly installed at the right end of the crushing box 1. A metal conduit 19 connected to the air pump 18 is fixedly installed on the outside of the air pump 18. A rotary joint 20 is installed between the reciprocating screw 12 and the metal conduit 19, and the rotary joint 20 is fixedly connected to the reciprocating screw 12. The metal conduit 19 is rotatably connected to the reciprocating screw 12 through the rotary joint 20. A cavity 21 is opened at one end of the reciprocating screw 12 near the rotary joint 20. A plurality of circumferentially distributed bent air pipes 22 are fixedly embedded on the outside of the reciprocating screw 12. The bent air pipes 22 are connected to the metal conduit 19 through the cavity 21. The air pump 18 inflates the hollow cutter shaft 3 through the bent air pipes 22. A gear ring 31 is fixedly sleeved on the outside of the rotary joint 20. A gear 32 is fitted on the outside of the gear ring 31. A motor 33 is installed on the right side of the gear 32, and the motor 33 is fixedly connected to the crushing box 1.

[0029] In this embodiment: During the rotation of the hollow cutter shaft 3, the air pump 18 operates. The air pump 18 injects gas into the hollow cutter shaft 3 through the bent air pipe 22. The gas inside the hollow cutter shaft 3 is discharged through the limiting straight groove of the moving cutting blade 15. This can effectively prevent a large number of lining fibers from entering the interior of the hollow cutter shaft 3 through the limiting straight groove during the crushing of the recycled lining, thereby preventing the lining from blocking the hollow cutter shaft 3.

[0030] Example 3: Please refer to Figure 4 , Figure 8This embodiment further explains Example 1. Two symmetrically distributed positioning rings 23 are movably sleeved on the outer side of the hollow cutter shaft 3. The two positioning rings 23 are located at opposite ends of the two positioning seats 9. A clearance groove 25 is provided on the outer side of the positioning ring 23 corresponding to the cutting blade 15. The cutting blade 15 is used to cut the lining wrapped around the outer side of the hollow cutter shaft 3. Multiple fixing screws 29 are movably embedded on the outer side of the positioning ring 23 and are distributed equidistantly in a circle. The connection between the fixing screws 29 and the hollow cutter shaft 3 is a threaded connection.

[0031] The grinding assembly includes two symmetrically distributed support blocks 24, and the support blocks 24 are fixedly connected to the positioning ring 23. The two support blocks 24 are located on both sides of the relief groove 25. Sharpening stones 26 are movably embedded on one side of the two support blocks 24, and the two sharpening stones 26 are connected by movable abutment. The sharpening stones 26 rub against the cutting blade 15, which can enhance the sharpness of the cutting blade 15.

[0032] The cross-sectional shape of the two whetstones 26 at one end is semi-circular. The whetstone 26 is located inside the support block 24 and is fixedly connected to a pad 27. The pad 27 can move inside the support block 24. The pad 27 is used to prevent the whetstone 26 from falling off the support block 24. Two symmetrically distributed springs 28 are fixedly installed on the side of the pad 27 away from the whetstone 26. The end of the spring 28 away from the pad 27 is in movable contact with the support block 24.

[0033] In this embodiment: During the reciprocating movement of the cutting blade 15 inside the hollow blade shaft 3, since the cross-sectional shape of the two whetstones 26 at one end is semi-circular, the cutting blade 15 can be inserted between the two whetstones 26 during the movement. The two whetstones 26 will contact and rub against the two sides of the cutting blade 15 under the drive of the compression force of the spring 28, which can automatically grind the blade edge of the cutting blade 15, thereby enhancing the sharpness of the cutting blade 15 and making the cutting blade 15 smoother during the transverse cutting of the recycled lining.
