Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric processing technology, and specifically to a cleaning device for nonwoven fabric processing. Background Technology

[0002] The nonwoven fabric production process uses polyethylene (PE) or polypropylene (PP) plastic granules as the main raw material. The resin is mixed with other functional additives (such as toughening agents, color masterbatches, etc.) according to the formula ratio through a feeding system. The mixture is heated to a molten state by an extruder (usually in the temperature range of 200-300℃) to form a uniform polymer melt. The molten polymer is transported to the spinning box by a metering pump and extruded through the spinneret to form continuous filaments. After being stretched and refined by high-speed airflow, the filaments are randomly laid into a fiber web. Low melting point fibers or powders are then added. Pressure (10-50MPa) and high temperature (120-180℃) are applied by hot rollers to melt and bond the surface fibers. The fiber web is then impacted by a high-pressure water jet to make the fibers entangle with each other. The finished product is soft and breathable.

[0003] However, when plastic granules are transported and mixed with resins and other functional additives, trace amounts of metal debris may remain in the virgin plastic granules due to equipment wear, incomplete screening, or other reasons during the production process. Some recycled materials (such as recycled plastic scrap) are more likely to be mixed with iron filings or rust due to their complex origins. Plastic granules mixed with iron impurities will form oxidation black spots during melt extrusion, resulting in visible spots or holes on the surface of the finished product, which damages the product quality. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, this utility model proposes a nonwoven fabric processing impurity removal device, including a bracket installed beside a belt conveyor. A feed hopper is fixed on the bracket and located directly above the feeding end of the belt conveyor. The feed hopper has a hollow inner cavity and an open bottom. The inner cavity of the feed hopper is provided with a separation component that separates iron impurities from the nonwoven fabric raw material. A partition is fixed in the middle of the inner cavity wall of the feed hopper. The inner cavity of the feed hopper is divided into a first chamber and a second chamber by the partition. A control component is installed inside the feed hopper to allow iron impurities to enter the first chamber and nonwoven fabric raw material to enter the second chamber.

[0005] To achieve the above objectives, the nonwoven fabric raw material and iron impurities mixed in with the nonwoven fabric raw material enter the feed hopper. The separation component separates the iron impurities from the nonwoven fabric raw material, allowing the nonwoven fabric raw material to enter the second chamber and the iron impurities to enter the first chamber. This reduces the possibility of iron impurities mixed in with the nonwoven fabric raw material and improves the quality of the nonwoven fabric product.

[0006] Furthermore, the control component includes a drive shaft disposed on the upper end of the partition and rotatably connected to the partition. The top end of the partition has an arc-shaped groove, the drive shaft extends into the arc-shaped groove and is rotatably connected to the arc-shaped groove, a guide plate is fixed on the drive shaft, and the front, rear sides and top of the guide plate are close to the inner wall of the feed hopper. A motor for driving the drive shaft to rotate is fixed on the feed hopper.

[0007] Furthermore, a discharge pipe is fixed at the bottom of the feed hopper, which communicates with the first chamber and is used to discharge iron impurities.

[0008] Furthermore, the separation component includes several circular holes formed on the feed hopper and located above the partition plate. The several circular holes are arranged in an array along the long side of the feed hopper. Each of the circular holes is slidably connected to a magnetic rod. One end of the magnetic rod is inserted into the feed hopper and abuts against the inner wall of the feed hopper cavity, while the other end is inserted out of the feed hopper. The portions of the several magnetic rods that are inserted out of the feed hopper are connected by a drive component.

[0009] Furthermore, the drive assembly includes a connecting rod fixed to a plurality of magnet rods extending out of the feed hopper. A mounting block is fixed at the middle position of the lower surface of the connecting rod. The mounting block has an oblong hole. A movable roller adapted to the oblong hole is movably connected in the oblong hole. Both ends of the movable roller extend out of the mounting block through the oblong hole. The movable roller extending out of the mounting block is rotatably connected to an adjacent oppositely arranged support plate. The support plate has a T-shaped cross section.

[0010] Furthermore, a base is fixed to the side of the bracket, and a support is fixed to the upper surface of the base. The top of the support is rotatably connected to two support plates via a first short shaft. A cylinder located next to the support is also fixed inside the base. The top of the cylinder extends out of the base, and the extended end of the cylinder is rotatably connected to the bottom end of the support plate via a second short shaft.

[0011] In summary, the impurity removal device for nonwoven fabric processing has the following beneficial effects: When the nonwoven fabric raw material and iron impurities mixed in with it enter the feed hopper, the iron impurities are separated from the nonwoven fabric raw material by the separation component. This allows the nonwoven fabric raw material to enter the second chamber, while the iron impurities enter the first chamber, reducing the possibility of iron impurities mixed in with the nonwoven fabric raw material and improving the quality of the nonwoven fabric product.

[0019] The technical solution of this utility model will be more clearly and completely explained below with reference to the accompanying drawings and through the description of the preferred embodiments of this utility model.

[0020] like Figure 1-5 As shown, the preferred embodiment of this utility model provides a nonwoven fabric processing impurity removal device, which includes a belt conveyor 1 that transports the screened nonwoven fabric raw material to the next process. A support 2 is provided on the side of the feed end of the belt conveyor 1, and a feed hopper 3 located directly above the belt conveyor 1 is fixed on the support 2. The feed hopper 3 has a hollow inner cavity and an open bottom end. A partition 5 is fixed in the middle of the inner cavity wall of the feed hopper 3. The inner cavity of the feed hopper 3 is divided into a first chamber 6 and a second chamber 7 by the partition 5. A separation component 4 is provided in the inner cavity of the feed hopper 3, located above the partition 5, to separate iron impurities from the nonwoven fabric raw material. A control component 8 is provided in the feed hopper 3 in conjunction with the separation component 4 to allow iron impurities to enter the first chamber 6 and the nonwoven fabric raw material to enter the second chamber 7.

[0021] like Figure 1 and Figure 2 and Figure 3 and Figure 4 and Figure 5 Nonwoven fabric raw materials and iron impurities mixed in the nonwoven fabric raw materials enter the feed hopper 3. The iron impurities are separated from the nonwoven fabric raw materials by the separation component 4, so that the nonwoven fabric raw materials enter the second chamber 7 and the iron impurities enter the first chamber 6.

[0022] like Figure 5The top of the partition 5 is provided with an arc-shaped groove. The control component 8 includes a drive shaft 801 that is mounted on the arc-shaped groove and rotatably connected to it. The outer wall of the drive shaft 801 is in contact with the inner wall of the arc-shaped groove. Both ends of the drive shaft 801 are rotatably connected to the inner wall of the feed hopper 3. A guide plate 802 is fixed on the drive shaft 801. The front, rear, and top sides of the guide plate 802 are close to the inner wall of the feed hopper 3. A rubber sealing plate is fixed on the outer side of the guide plate 802 to close the gap between the guide plate 802 and the inner wall of the feed hopper 3. A motor 803 that drives the drive shaft 801 to rotate is fixed on the feed hopper 3.

[0023] like Figure 5 Power is provided by motor 803, which drives the transmission shaft 801, which is coaxially fixed with the output shaft of motor 803, to rotate. When the transmission shaft 801 rotates to contact the left side of the inner cavity wall of the feed hopper 3, the non-woven fabric raw material entering the feed hopper 3 can only enter the second chamber 7 and be discharged from the bottom of the second chamber 7. When the transmission shaft 801 rotates to contact the right side of the inner cavity wall of the feed hopper 3, the iron impurities in the feed hopper 3 can only enter the first chamber 6 and be discharged from the bottom of the first chamber 6.

[0024] like Figure 1 and Figure 2 and Figure 3 In order to reduce the amount of iron impurities falling into the belt conveyor 1 and entering the next process, the bottom of the feed hopper 3 is fixed with a discharge pipe 804 that communicates with the first chamber 6 and is used to discharge iron impurities. The end of the discharge pipe 804 away from the first chamber 6 is connected to the collection box for collecting iron impurities. The non-woven fabric raw material discharged from the second chamber 7 will fall directly onto the belt conveyor and enter the next process. The iron impurities discharged from the bottom of the second chamber 7 will directly enter the discharge pipe 804 and be discharged into the collection box by the discharge pipe 804.

[0025] like Figure 2 and Figure 4 and Figure 5 The separation component 4 includes several circular holes 401 formed on the feed hopper 3 and located above the partition plate 5. The circular holes 401 connect the outside to the inner cavity of the feed hopper 3. The circular holes 401 are arranged in an array along the long side of the feed hopper 3. Each circular hole 401 is slidably connected to a magnetic rod 402. The magnetic rods 402 are close to each other, and the gap between each two adjacent magnetic rods 402 is sufficient to allow non-woven fabric particles to pass through. One end of the magnetic rod 402 is inserted into the feed hopper 3 and abuts against the inner cavity wall of the feed hopper 3. A rubber pad is fixed to the end of the magnetic rod 402 that abuts against the inner cavity wall of the feed hopper 3, and the other end extends out of the feed hopper 3. The parts of the magnetic rods 402 that extend out of the feed hopper 3 are connected by a drive component.

[0026] like Figure 2 and Figure 4 and Figure 5In the initial state, the end of the magnet 402 contacts the inner wall of the feed hopper 3. The non-woven fabric material entering the feed hopper 3 will contact the magnet 402 and fall through the gap between the magnets 402. After the non-woven fabric material is fed, the drive component provides power to drive the magnet 402 to move in the direction of moving out of the feed hopper 3. At this time, the iron impurities adsorbed on the magnet 402 will detach from the magnet 402 and fall into the feed hopper 3.

[0027] like Figure 2 and Figure 3 and Figure 4 The drive assembly includes a connecting rod 403 fixed to several magnet rods 402 extending out of the feed hopper 3. A mounting block 404 is fixed at the middle of the lower surface of the connecting rod 403. The mounting block 404 has an oblong hole, and a matching movable roller 405 is movably connected within the oblong hole. Both ends of the movable roller 405 extend out of the mounting block 404 through the oblong hole. The movable roller 405 extending out of the mounting block 404 is rotatably connected to an adjacent, oppositely arranged support plate 406. The support plate 406 has a T-shaped cross-section. A base 407 is fixed to the side of the bracket 2. A support 408 is fixed on the upper surface of 407. The top of the support 408 is rotatably connected to two support plates 406 via a first short shaft 409. A cylinder 410 located next to the support 408 is also fixed inside the base 407. The top of the cylinder 410 extends out of the base 407. The extended end of the cylinder 410 is rotatably connected to the bottom of the support plate 406 via a second short shaft 411. Power is provided by the cylinder 410 to drive the two support plates 406 to rotate. The rotation of the support plates 406 will push the connecting rod 403 and the magnet 402 fixed to the connecting rod 403 to move.

[0028] When in use, connect the power supply, turn on the switch, and the operator turns on the motor 803. The motor 803 provides power to drive the transmission shaft 801, which is fixed coaxially with the output shaft of the motor 803, to rotate. The transmission shaft 801 rotates until the guide plate 802 abuts against the left end of the inner cavity wall of the feed hopper 3. At this time, the top of the first chamber 6 is closed by the guide plate 802, and the motor 803 is turned off.

[0029] At this time, the staff pours the non-woven fabric raw material into the feed hopper 3 from above. The non-woven fabric raw material entering the feed hopper 3 will first come into contact with the magnet 402. At this time, the iron impurities mixed in the non-woven fabric raw material will be adsorbed by the magnet 402 and adhere to the magnet 402. The iron impurities that have been screened pass through the magnet 402 and enter the second chamber 7, and are discharged from the bottom of the second chamber 7 onto the belt conveyor 1.

[0030] After feeding is completed, turn on motor 803. Power is provided by motor 803 to drive the transmission shaft 801, which is fixed coaxially with the output shaft of motor 803, to rotate in reverse. The transmission shaft 801 rotates until the guide plate 802 abuts against the right end of the inner cavity wall of the feeding hopper 3. At this time, the second chamber 7 is closed by the guide plate 802, and motor 803 is turned off.

[0031] The operator opens cylinder 410, which provides power to rotate support plate 406 around the first short axis 409. The rotation of support plate 406 will drive connecting rod 403 to move, which in turn will drive magnetic rod 402, which is integrated with connecting rod 403, to move within circular hole 401. As magnetic rod 402 moves outward, iron impurities adhering to magnetic rod 402 are scraped off by the wall of feed hopper 3. The scraped iron impurities will fall directly into the first chamber 6 and be discharged through discharge pipe 804. The filtered iron impurities will enter the collection box for collection.

Various modifications, substitutions, and improvements made by those skilled in the art to the technical solutions of the present invention based on the provided description and drawings, without departing from the design concept and spirit of the present invention, should all fall within the scope of protection of the present invention. The scope of protection of the present invention is determined by the claims.
