Description
Technical Field
[0001] The present invention belongs to the technical field of fabric processing equipment, and specifically relates to an energy-saving fabric shredding device. Background Art
[0002] During the production process of textile fabrics, a large amount of scrap materials will be generated, such as the remaining materials after cutting, defective fabrics, etc. If directly discarded, it will not only cause waste of resources but also increase the environmental burden. In order to improve the resource utilization rate and reduce pollution, these scrap materials can be recycled through recycling technology and reused in production to create new value. For example, shredded fabrics can be reused after being broken; they can also be used as filling materials for raw materials of products such as cushions and plush toys.
[0003] However, the above technologies often have the following defects: In the current process of recycling and crushing fabric scrap materials, due to the significant difference in the size of the raw materials, larger pieces of fabric need to be coarsely crushed in a low-speed and high-torque mode to ensure effective tearing without damaging the cutting tools, while smaller pieces of fabric are suitable for high-speed fine crushing to obtain uniform fibrous materials. If a unified high-speed rotation is used to process fabrics of mixed sizes, it will not only cause insufficient crushing of large pieces of fabric and uneven shredded materials, but also cause unnecessary additional energy consumption due to continuous high-load operation. Therefore, the present invention provides an energy-saving fabric shredding device. Summary of the Invention

[0024] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.
[0025] Example 1: As Figures 1 to 5As shown in the figure, an energy-saving fabric waste shredding device according to an embodiment of the present invention includes a housing 1; a crushing chamber 3 is provided inside the housing 1, a rotating shaft 4 is arranged in the crushing chamber 3, and a plurality of groups of blades 5 are fixedly connected to the rotating shaft 4. A motor for driving the rotation of the rotating shaft 4 is arranged on the top surface of the housing 1; a material distribution chamber 8 is provided inside the housing 1, a feed slot 6 communicating with the material distribution slot is provided on the top surface of the housing 1, a feed hopper 2 communicating with the feed slot 6 is fixedly connected to the top surface of the housing 1, and a connection slot 11 communicating with the material distribution chamber 8 and the crushing chamber is provided inside the housing 1; a discharge slot 7 communicating with the crushing chamber is provided on the bottom surface of the housing 1. First guide plates 9 and second guide plates 10 are arranged on the inner wall of the material distribution chamber 8. The first guide plates 9 and the second guide plates 10 are inclined and symmetrically arranged in a staggered manner, and a group of through slots are provided on the second guide plates 10.
[0026] In this application, the fabric is placed into the feed hopper 2, and then the motor is used to drive the rotating shaft 4 to rotate at a high speed, so that the blades 5 rotate. At this time, the blades 5 will generate suction due to the high speed, and the suction will act on the material distribution slot through the connection slot 11. At this time, the fabric entering the material distribution slot from the feed hopper 2 will first slide on the first guide plate 9. At this time, the generated suction can suck the smaller fabric into the crushing chamber and then be broken by the blades 5. The large fabric will slide to the material distribution chamber 8 through the second guide plate 10 for storage. The cooperation of the first guide plate 9 and the second guide plate 10 can extend the use time of the fabric passing through the connection slot 11, so that the small fabric can have sufficient time to be sucked away. After all the fabric is distributed in the material distribution chamber 8, the rotation speed of the motor driving the rotating shaft 4 can be reduced, and then the large fabric in the material distribution chamber 8 can be concentrated and broken. Through the above mechanism, the large fabric and the small fabric can be separated and processed, which can improve the uniformity of fabric crushing and achieve the effect of energy saving on the one hand.
[0027] A discharge plate 13 is arranged in the material distribution chamber 8. The top surface of the discharge plate 13 is inclined. A lead screw 12 is threadedly connected to the discharge plate 13. A motor for driving the rotation of the lead screw 12 is arranged on the inner wall of the material distribution chamber 8. When the fabric in the material distribution chamber 8 needs to be crushed in this application, the motor can be used to drive the lead screw 12 to rotate, so that the discharge plate 13 moves upward. At this time, the discharge plate 13 will push the fabric in the material distribution chamber 8 upward and then discharge it into the crushing chamber through the connection slot 11 to be broken.
[0028] The discharge plate 13 is in sealed sliding connection with the inner wall of the material distribution chamber 8. A chute 14 and a cavity 15 are provided inside the housing 1. The bottom end of the chute 14 communicates with the material distribution chamber 8, the top end of the chute 14 communicates with the cavity 15, and a plurality of air outlet holes 16 communicating with the cavity 15 are provided on the inner wall of the material distribution chamber 8.
[0029] In this application, the lead screw 12 can drive the discharge plate 13 to move up and down reciprocally. When the discharge plate 13 moves downward, the discharge plate 13 will push the gas in the material distribution chamber 8 into the chute 14, then into the cavity 15, and finally blow out from the air outlet hole 16. The gas can act on the first guide plate 9 and the second guide plate 10 to prevent fabrics from getting stuck on the first guide plate 9 and the second guide plate 10. If there are small fabrics with relatively heavy quality in a fabric batch, when the blade 5 rotates at high speed, the movement of the discharge plate 13 can be utilized to make the air outlet hole 16 blow air, increasing the blowing force on the fabrics to better distinguish small fabrics from large fabrics.
[0030] A gas guide groove 17 communicating with the material distribution chamber 8 is opened in the housing 1. The inner wall of the crushing chamber close to the lead screw 12 is fixedly connected with a hollow plate 18. A through hole 19 communicating with the hollow plate 18 is opened on the inner wall of the gas guide groove 17. An avoidance groove 21 is opened on the surface of the hollow plate 18. An air suction hole 20 is opened on one side of the hollow plate 18 close to the lead screw 12. One-way components are arranged in both the gas guide groove 17 and the chute 14; the one-way component in the guide groove is an intake one-way member, and the one-way member in the chute 14 is an exhaust one-way member. When the discharge plate 13 moves upward, gas needs to be inhaled into the powder chamber. At this time, a suction force will be generated at the air suction hole 20 to suck the gas into the hollow plate 18, and then it will enter the material distribution chamber 8 along the through hole 19 and the gas guide groove 17. The suction force generated at the air suction hole 20 can further assist in sucking smaller fabrics into the crushing chamber, improving the effect of distinguishing fabrics.
[0031] The one-way component includes a first sealing plate 22 arranged on the inner wall of the gas guide groove 17. The first sealing plate 22 is connected to the gas guide groove 17 through a torsion spring. The side of the first sealing plate 22 away from the hollow plate 18 fits and seals with the inner wall of the gas guide groove 17. The inner wall of the chute 14 is torsionally connected with a second sealing plate 23 through a torsion spring. The bottom surface of the second sealing plate 23 fits and seals with the inner wall of the chute 14; due to the arrangement of the first sealing plate 22 and the second sealing plate 23, the first sealing plate 22 can only rotate counterclockwise, and the second sealing plate 23 can only rotate clockwise. When the discharge plate 13 moves downward, it will push the gas in the material distribution chamber 8 into the chute 14 to push the second sealing plate 23, so that the second sealing plate 23 no longer fits with the inner wall of the chute 14. At this time, the gas can be discharged from the air outlet hole 16. When the discharge plate 13 moves upward, the torsion spring will drive the second sealing plate 23 to reset, thereby sealing the chute 14. At the same time, the first sealing plate 22 will be sucked by the suction force and no longer seal the gas guide groove 17. At this time, a suction force can be generated at the air suction hole 20.
[0032] Embodiment 2: As Figure 6As shown, compared with the first comparative example, another implementation manner of the present invention is as follows: both the first guide plate 9 and the second guide plate 10 are rotatably connected to the inner wall of the material distribution cavity 8 through a rotating shaft 4. A hollow block 24 that fits the first guide plate 9 is fixedly connected to the inner wall of the material distribution cavity 8. The hollow block 24 is made of an elastic material. A connecting line 25 is connected between the first guide plate 9 and the second guide plate 10. An air injection assembly for injecting air into the hollow block 24 is arranged in the chute 14. In this application, when the fabric enters the material distribution cavity 8, the fabric will first pass through the first guide plate 9 and the second guide plate 10. At this time, the air injection assembly can be used to inject air into the hollow block 24. Then the hollow block 24 will expand and push the first guide plate 9 to rotate. At the same time, the connecting line 25 will also pull the second guide plate 10 to rotate. Then the gas in the hollow block 24 is discharged. At this time, both the first guide plate 9 and the second guide plate 10 will rotate downward. Repeating such operations can make the first guide plate 9 and the second guide plate 10 rotate repeatedly to assist the fabric to slide off the guide plate and the second guide plate 10.
[0033] The air injection assembly includes a moving block 29 that is hermetically and slidably connected to the inner wall of the chute 14. The bottom surface of the moving block 29 is conical. A hollow rod 26 is fixedly connected to the top surface of the moving block 29. A sliding rod 27 is hermetically and slidably connected to the top end of the hollow rod 26. A first spring is fixedly connected between the bottom surface of the sliding rod 27 and the inner wall of the hollow rod 26. A connecting pipe 28 is connected between the hollow rod 26 and the hollow block 24. In this application, when the discharge plate 13 moves downward, it will push the gas in the material distribution cavity 8 into the chute 14. At this time, the gas will push the moving block 29 upward, so that the sliding rod 27 is pushed by the top surface of the inner wall of the cavity 15, so that the sliding rod 27 pushes the gas in the hollow rod 26 to enter the hollow block 24 through the connecting pipe 28, causing the hollow block 24 to expand and push the first guide plate 9 to rotate.
[0034] A conduit is connected to the chute 14. A control valve is arranged in the conduit. A guide rod 30 is fixedly connected to the inner wall of the chute 14. The top end of the guide rod 30 is slidably connected to the moving block 29. A second spring is fixedly connected between the moving block 29 and the guide rod 30. In this application, when the moving block 29 is pushed upward and the gas continuously enters the chute 14, the moving block 29 will continue to move upward until a gap is generated between the conical surface of the moving block 29 and the chute 14. At this time, the gas can enter the cavity 15 from the chute 14 and then be discharged from the air outlet 16. When the discharge plate 13 stops moving downward, the second spring will pull the moving block 29 downward. After the side wall of the moving block 29 fits the chute 14, it will be hermetically and slidably connected. At this time, the gas in the chute 14 will be pushed by the moving block 29 and then discharged through the conduit. When it is necessary to discharge the gas from the conduit, the control valve can be opened.
[0035] Working principle: Place the fabric into the feed hopper 2, and then drive the rotating shaft 4 to rotate at a high speed by means of a motor, so that the blade 5 rotates. At this time, the blade 5 will generate suction due to the high speed, and the suction will act on the material distribution groove through the connecting groove 11. At this time, the fabric entering the material distribution groove from the feed hopper 2 will first slide on the first guide plate 9. The suction generated at this time can suck the smaller fabric into the crushing cavity and then be broken by the blade 5. The large fabric will slide to the material distribution cavity 8 through the second guide plate 10 for storage. The cooperation of the first guide plate 9 and the second guide plate 10 can extend the use time of the fabric passing through the connecting groove 11, so that the small fabric can have sufficient time to be sucked away. After all the fabric is distributed in the material distribution cavity 8, the rotation speed of the motor driving the rotating shaft 4 can be reduced, and then the large fabric in the material distribution cavity 8 can be concentrated and broken. Through the above mechanism, the large fabric and the small fabric can be separated and processed. On the one hand, it can improve the uniformity of fabric crushing, and on the other hand, it can achieve the effect of energy conservation; when the fabric in the material distribution cavity 8 needs to be crushed in this application, the motor can be used to drive the screw rod 12 to rotate, so that the discharge plate 13 moves upward. At this time, the discharge plate 13 will push the fabric in the material distribution cavity 8 upward and then discharge it from the connecting groove 11 into the crushing cavity to be broken;
[0036] In this application, the screw rod 12 can drive the discharge plate 13 to move up and down reciprocally. When the discharge plate 13 moves downward, the discharge plate 13 will push the gas in the material distribution cavity 8 into the chute 14, then into the cavity 15, and finally blow out from the air outlet 16. The gas can act on the first guide plate 9 and the second guide plate 10 to prevent the fabric from getting stuck on the first guide plate 9 and the second guide plate 10. If the quality of the small fabric is also relatively heavy in a fabric batch, when the blade 5 rotates at a high speed, the discharge plate 13 can be moved to make the air outlet 16 blow air, increasing the blowing force on the fabric to better distinguish the small fabric and the large fabric;
[0037] The one-way component of the guide groove is the intake one-way part, and the one-way part in the chute 14 is the exhaust one-way part. When the discharge plate 13 moves upward, gas needs to be inhaled into the powder cavity. At this time, a suction force will be generated at the suction hole 20 to suck the gas into the hollow plate 18, and then along the through hole 19 and the air guide groove 17 into the material distribution cavity 8. The suction force generated at the suction hole 20 can further assist in sucking smaller fabrics into the crushing cavity, improving the effect of differentiating fabrics. Due to the setting of the first sealing plate 22 and the second sealing plate 23, the first sealing plate 22 can only rotate counterclockwise, and the second sealing plate 23 can only rotate clockwise. When the discharge plate 13 moves downward, it will push the gas in the material distribution cavity 8 into the chute 14 to push the second sealing plate 23, so that the second sealing plate 23 no longer fits against the inner wall of the chute 14. At this time, the gas can be discharged from the air outlet hole 16. When the discharge plate 13 moves upward, the torsion spring will drive the second sealing plate 23 to reset, thereby sealing the chute 14. At the same time, the first sealing plate 22 will be sucked by the suction force and no longer seal the air guide groove 17. At this time, a suction force can be generated at the suction hole 20.
