Description

Technical Field

[0001] This utility model belongs to the field of fabric recycling and processing technology, specifically relating to a fabric scrap processing device. Background Technology

[0002] Fabric scrap processing equipment is a key piece of equipment for the resource utilization of waste in the textile industry. It is mainly used to recycle waste materials such as scraps and offcuts generated during garment production and textile processing. Traditional treatment methods include landfilling, incineration, or simple crushing for use in low-value-added products (such as filling materials).

[0003] Existing technologies mostly employ a processing flow that combines mechanical crushing with manual sorting. Typical equipment includes shredders, vibrating screens, and compression balers. For example, a twin-shaft shredder is used to break fabric into fragments, which are then manually sorted into different materials (such as cotton, polyester, and spandex).

[0004] The problem of fiber dust generated during the crushing process has long remained unresolved. Fiber dust permeates the workshop during crushing, and long-term exposure can easily lead to respiratory diseases among workers. At the same time, dust adsorbed by electrostatics can easily cause short circuits in equipment, increasing the equipment failure rate. Although some devices currently add dust collection devices to the crushing port, only a small portion of the dust is generated when the fabric scraps are shredded. A large amount of dust remains in the fragments and is difficult to remove effectively. The remaining dust will still have a significant adverse impact during subsequent sorting and packaging. Utility Model Content

[0005] To address the above problems, the purpose of this utility model is to provide a fabric scrap processing device that solves the problem that although some devices add a dust suction device to the shredding port, only a small portion of the dust is generated when the fabric scraps are shredded, and a large amount of dust remains in the fragments that is difficult to remove effectively. As a result, the remaining dust still has a significant adverse effect on subsequent sorting and packaging.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a fabric scrap processing device, comprising a crushing box, crushing rollers rotatably connected side-by-side on the upper inner side of the crushing box, the crushing rollers meshing with each other, a motor being installed on the side of the crushing box corresponding to each crushing roller, the output end of the motor penetrating into the inner side of the crushing box and fixedly connected to the crushing roller, four foot rods fixedly connected to the lower corners of the crushing box, a discharge port being opened in the middle of the side of the crushing box away from the motor, below the crushing roller, a receiving plate being fixedly installed on the lower inner side of the crushing box, the receiving plate being inclined downwards towards the discharge port, a fixing cylinder being fixedly installed on the side of the crushing box outside the discharge port, the fixing cylinder being inclined downwards towards the side away from the crushing box, a support frame being fixedly installed on the lower side of the fixing cylinder, and the inner side of the fixing cylinder being coaxial. The device is equipped with a roller. A ring rail is fixedly mounted side-by-side on the inner side of the fixed cylinder. A connecting ring is slidably engaged on the inner side of the ring rail and fixedly connected to the outer side of the roller. A second motor is fixedly mounted on the lower side of the fixed cylinder, away from the crushing chamber. A transmission wheel is fixedly connected to the output end of the second motor. A transmission ring is fixedly connected to the roller protruding from the fixed cylinder on the side away from the crushing chamber. A belt connects the transmission wheel and the transmission ring. A lever is fixedly mounted equidistantly around the inner side of the roller. Through holes are uniformly formed on the surface of the transmission ring. A first dust collection head is connected to the ring rail on the upper side of the fixed cylinder. A powerful centrifugal fan is fixedly mounted on the side of the crushing chamber. A dust collection pipe connects the output end of the first dust collection head and the powerful centrifugal fan. A baghouse dust collection box is connected to the output end of the powerful centrifugal fan.

[0007] The beneficial effects of this invention are as follows: When the roller rotates, it drives the lever to continuously agitate the fabric fragments. The fabric fragments are continuously impacted and agitated by the lever, causing the dust between the fabric fragments to detach and disperse. At this time, the powerful centrifugal fan starts simultaneously, drawing air through the suction pipe to the suction head. The suction head then draws air into the fixed cylinder. The dust inside the roller passes through the through holes and is then sucked away by the suction head, finally being sent to the dust collection box in the cloth bag for filtration and collection. After the fabric is torn, the fabric fragments can be repeatedly agitated to detach and disperse the dust, which is then sucked away and collected. This can remove a large amount of dust from the fabric fragments, avoiding the presence of excessive dust in the fabric fragments and thus greatly reducing the adverse effects of dust on subsequent processes.

[0008] In order to gather and slide the fabric fragments on the upper side of the receiving plate toward the discharge port;

[0009] As a further improvement to the above technical solution: symmetrical guide plates are fixedly arranged on the upper side of the receiving plate, and the guide plates move closer to each other towards the discharge port.

[0010] The beneficial effects of this improvement are: the material guide plate is set up to slide and gather the fabric fragments on the upper side of the receiving plate toward the discharge port.

[0011] For use in filtering and collecting more noticeable fibrous debris;

[0012] As a further improvement to the above technical solution: the crushing box is provided with a slag collection tray on the same side of the motor, and the receiving plate is a coarse mesh plate.

[0013] The beneficial effect of this improvement is that it can be used to filter and collect more obvious fiber debris.

[0014] For use in feeding and storing materials during crushing;

[0015] As a further improvement to the above technical solution: a hopper is fixedly connected to the upper side of the crushing box.

[0016] The beneficial effect of this improvement is that it can be used for feeding and storing materials during crushing.

[0017] To absorb the dust generated during crushing;

[0018] As a further improvement to the above technical solution: a second suction head is connected to one side of the hopper, and a three-way pipe is connected to the output end of the second suction head. The lower side of the three-way pipe is connected to a first suction head, and the upper side of the three-way pipe is connected to a suction pipe.

[0019] The beneficial effect of this improvement is that it can absorb the dust generated during crushing.

[0020] To facilitate the rolling of the rollers within the fixed cylinder;

[0021] As a further improvement to the above technical solution: the inner side of the ring rail is provided with rollers that rotate equidistantly around it, and the outer side of the connecting ring is connected to the rollers for transmission.

[0022] The beneficial effect of this improvement is that it facilitates the rolling of the roller within the fixed cylinder.

[0023] In order to quickly remove and clean the dust collected inside the bag dust collection box;

[0032] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0033] like Figure 1 — Figure 4As shown: A fabric scrap processing device includes a crushing box 1. Crushing rollers 2 are rotatably connected side-by-side to the upper inner side of the crushing box 1, and the crushing rollers 2 mesh with each other. Motors 3 are installed on the side of the crushing box 1 corresponding to each crushing roller 2. The output end of each motor 3 passes through the inner side of the crushing box 1 and is fixedly connected to the crushing roller 2. Foot rods 5 are fixedly connected to the four corners of the lower side of the crushing box 1. A discharge port 7 is opened in the middle of the side of the crushing box 1 away from the motors 3, below the crushing roller 2. A receiving plate 6 is fixedly installed on the lower inner side of the crushing box 1, and the receiving plate 6 is inclined downwards towards the discharge port 7. A fixing cylinder 9 is fixedly installed on the side of the crushing box 1 outside the discharge port 7, and the fixing cylinder 9 is inclined downwards towards the side of the crushing box 1. The fixed cylinder 9 is inclined downwards on one side. A support frame 10 is fixedly installed on the lower side of the fixed cylinder 9. A roller 11 is coaxially installed on the inner side of the fixed cylinder 9. A ring rail 12 is fixedly installed side by side on the inner side of the fixed cylinder 9. A connecting ring 13 is slidably engaged on the inner side of the ring rail 12. The connecting ring 13 is fixedly connected to the outer side of the roller 11. A motor 14 is fixedly installed on the lower side of the fixed cylinder 9 away from the crushing box 1. A transmission wheel 15 is fixedly connected to the output end of the motor 14. A transmission ring 16 is fixedly connected to the side of the roller 11 away from the crushing box 1, protruding from the fixed cylinder 9. A belt 17 is connected between the transmission wheel 15 and the transmission ring 16. A lever is fixedly connected to the inner side of the roller 11 at equal intervals. The surface of the 16 is uniformly perforated with through holes. A dust suction head 18 is connected to the upper side of the fixed cylinder 9 between the ring rail 12 and the fixed cylinder 9. A powerful centrifugal fan 20 is fixedly installed on the side of the crushing box 1. A dust suction pipe 21 is connected between the output end of the dust suction head 18 and the powerful centrifugal fan 20. A bag dust collection box 22 is connected to the output end of the powerful centrifugal fan 20. When the roller 11 rotates, it drives the lever to continuously move the fabric fragments. The fabric fragments are continuously impacted and moved by the lever, and the dust between the fabric fragments will detach from the fabric and float out. At this time, the powerful centrifugal fan 20 starts synchronously. The powerful centrifugal fan 20 draws air to the dust suction head 18 through the dust suction pipe 21. The dust suction head 18 draws air into the fixed cylinder 9, and the dust in the roller 11 is collected. After passing through the through-hole and roller 11, the dust is sucked away by the suction head 18 and finally sent to the bag dust collection box 22 for filtration and collection. This allows for repeated agitation of the fabric fragments after tearing, causing the dust to dissipate and be collected, thus significantly removing a large amount of dust from the fabric fragments and minimizing the adverse effects of dust on subsequent processes. The receiving plate 6 has symmetrically fixed guide plates 8 on its upper side, which converge towards the discharge port 7. These guide plates 8 are used to slide and gather the fabric fragments on the upper side of the receiving plate 6 towards the discharge port 7. The crushing box 1 has a slag collection tray 24 that can be pulled out from the lower side of the same side as the motor 3. The receiving plate 6 is a coarse mesh plate.For filtering and collecting more obvious fiber debris, a hopper 4 is fixedly connected to the upper side of the crushing box 1 for feeding and storing material during crushing. A second suction head 23 is connected to one side of the hopper 4. A three-way pipe 19 is connected to the output end of the second suction head 23. The lower side of the three-way pipe 19 is connected to a first suction head 18, and the upper side of the three-way pipe 19 is connected to a suction pipe 21 for absorbing dust generated during crushing. Rollers are equidistantly arranged around the inner side of the ring track 12. The outer side of the connecting ring 13 is connected to the roller drive, facilitating the rolling of the roller 11 within the fixed cylinder 9. The bag dust collection box 22 includes a box body, with a pull-out drawer on one side of the box body. An air outlet is located on the side of the pull-out drawer, and a cloth bag is placed inside the drawer. The output end of the powerful centrifugal fan 20 is connected to the upper side of the box body. By pulling the drawer out of the box body, the cloth bag can be directly removed and replaced, allowing for quick removal and cleaning of the dust collected inside the bag dust collection box 22.

[0034] Working principle and usage process of this utility model:

[0035] In operation, motor 3 is started, and its output drives the crushing rollers 2 to rotate. The crushing rollers 2 rotate in opposite directions and engage to tear the fabric, shredding it. The shredded fabric falls onto the receiving plate 6, then is guided from the receiving plate 6 to the discharge port 7, and finally discharged from the discharge port 7 into the inner side of the drum 11. Motor 14 is then started, and its output drives the transmission wheel 15 to rotate. The transmission wheel 15 and the transmission ring 16 are connected by a belt 17, causing the drum 11 to rotate with the transmission ring 16. The rotation of the drum 11 drives the lever... By repeatedly agitating the fabric fragments with the lever, the fabric fragments are continuously struck and moved, causing dust to detach from the fabric and disperse. Simultaneously, a powerful centrifugal fan 20 starts, drawing air through the suction pipe 21 to the suction head 18. The suction head 18 then draws air into the fixed cylinder 9. Dust and other particles inside the roller 11 pass through the through-holes and are then sucked away by the suction head 18, ultimately being filtered and collected in the bag dust collection box 22. This process allows for continued agitation of the fabric fragments even after they have been torn into pieces. The dust in the block is detached and dispersed, then sucked away and collected, which can remove a large amount of dust from the fabric fragments, avoiding excessive dust residue and greatly reducing the adverse effects of dust on subsequent processes. In addition, guide plates 8 are symmetrically fixed on the upper side of the receiving plate 6. The guide plates 8 move towards the discharge port 7 and are used to slide and gather the fabric fragments on the upper side of the receiving plate 6 towards the discharge port 7. Furthermore, a slag collection tray 24 is pulled out and installed on the lower side of the crushing box 1 on the same side as the motor 3. The receiving plate 6 is a coarse mesh plate. The crushing box 1 is used to filter and collect relatively obvious fiber fragments. In addition, a hopper 4 is fixedly connected to the upper side of the crushing box 1 for feeding and storing materials during crushing. In addition, a second dust suction head 23 is provided to absorb the dust generated during crushing. In addition, rollers are equidistantly arranged around the inner side of the ring rail 12, and the outer side of the connecting ring 13 is connected to the rollers for transmission, which facilitates the rolling of the roller 11 in the fixed cylinder 9. In addition, the dust collected inside the bag dust collection box 22 can be quickly removed and cleaned by pulling out the drawer from the box and then directly taking out the cloth bag for replacement.
