Description

Technical Field

[0001] This invention relates to the field of nonwoven fabric technology, specifically to a nonwoven fabric and a perforation device for preventing nonwoven fabric from snagging. Background Technology

[0002] Nonwoven fabric is a non-woven material composed of fibers or fiber assemblies. Unlike traditional textiles, it does not require spinning or weaving processes; instead, it is formed by directly bonding, welding, or mechanizing fibers. Nonwoven fabrics are typically made from synthetic fibers such as polypropylene, polyester, and nylon, or natural fibers, and are widely used in medical and health, agriculture, household goods, clothing, packaging, and building materials industries.

[0003] To increase the breathability, water permeability, softness, and comfort of nonwoven fabrics, perforation is required during the nonwoven fabric processing. Traditional nonwoven fabric perforation often uses the piercing method, employing specialized piercing equipment or machines to mechanically pierce the nonwoven fabric and create holes. Due to the soft nature of nonwoven fabrics, the fabric is prone to movement after perforation, and after removing the piercing pins, the nonwoven fabric is easily carried along with the pins, leading to inaccurate perforation accuracy. To address these issues, we propose a nonwoven fabric and an anti-slip perforation device for nonwoven fabrics. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. By setting up a perforation mechanism, the nonwoven fabric body is automatically conveyed.

Thus, the nonwoven fabric body is automatically heat-sealed and perforated by multiple heat-sealing rings, preventing the nonwoven fabric body from being attached to the perforation mechanism and affecting the perforation effect of the nonwoven fabric. Since there are notches on the heat-sealing rings, the waste generated by perforation sticks to the nonwoven fabric body, preventing the waste generated by perforation from being attached to the perforation mechanism and affecting the perforation effect of the nonwoven fabric, and facilitating the subsequent collection of waste.

[0017] 2. The hole-cleaning mechanism is used in conjunction with the setting to use multiple ring cutters to cut and separate the waste generated by punching into the non-woven fabric body, and leave it in the waste collection hole, thereby realizing the cutting, separation and automatic collection of waste.

[0018] 3.

[0037] 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.

[0038] Example: Figure 1-16 As shown, the present invention provides a nonwoven fabric, including a nonwoven fabric body 1, the nonwoven fabric body 1 including a nonwoven fabric layer 11, a reinforcing layer 12 provided on the surface of the nonwoven fabric layer 11, a high-temperature resistant layer 13 provided on the side of the reinforcing layer 12 away from the nonwoven fabric layer 11, an insulating layer 14 provided on the side of the high-temperature resistant layer 13 away from the reinforcing layer 12, an antibacterial layer 15 provided on the side of the nonwoven fabric layer 11 away from the reinforcing layer 12, and a waterproof layer 16 provided on the side of the antibacterial layer 15 away from the nonwoven fabric layer 11. By setting the reinforcing layer 12, the overall tensile strength of the nonwoven fabric body 1 is increased; by setting the high-temperature resistant layer 13, the high-temperature resistance on one side of the nonwoven fabric body 1 is improved; by setting the insulating layer 14, the insulation effect on one side of the nonwoven fabric body 1 is improved; by setting the antibacterial layer 15, the insulation effect on the other side of the nonwoven fabric body 1 is improved; and by setting the waterproof layer 16, the waterproof effect on the other side of the nonwoven fabric body 1 is improved.

[0039] A perforation device for preventing nonwoven fabric from sticking together includes a support frame 2. Two symmetrically distributed device side frames 21 are fixedly installed on the top of the support frame 2. A connecting frame 22 is fixedly installed between the two device side frames 21. A perforation mechanism 3 is provided on one side of the middle of the device side frame 21, and a hole cleaning mechanism 4 is provided on the other side of the middle of the device side frame 21. A cutting piece 5 is provided on the side of the device side frame 21 near the perforation mechanism 3. A collecting piece 6 is provided on the top of the device side frame 21 near the perforation mechanism 3. A first guide roller 7 is rotatably installed on both sides of the top of the connecting frame 22. Two second guide rollers 8 are symmetrically distributed vertically on the side of the device side frame 21 away from the cutting piece 5.

[0040] The cutting component 5 includes two symmetrically distributed pressing rollers 51. The pressing rollers 51 are rotatably mounted on the side frame 21 of the device near the punching mechanism 3. A fourth gear 511 is fixedly mounted at one end of each pressing roller 51, and the two fourth gears 511 mesh with each other. A ring seat 52 is movably sleeved on the outer side of the pressing roller 51, and a cutting blade 53 is fixedly mounted on the outer side of the ring seat 52. A fastening screw 521 is threaded onto the ring seat 52, and the end of the fastening screw 521 contacts the outer wall of the pressing roller 51, cutting the width according to the nonwoven fabric body 1. According to the requirements, the sliding ring seat 52 adjusts the distance between the two cutting blades 53 and is fastened with fastening screws 521. In use, the non-woven fabric body 1 is passed around the first guide rollers 7 on both sides and passes through the two pressing rollers 51. By driving one of the pressing rollers 51 to rotate, and cooperating with the meshing connection of the fourth gear 511, the other pressing roller 51 is driven to rotate synchronously in the opposite direction. Thus, the cutting blades 53 on both sides automatically cut the edge of the automatically conveyed non-woven fabric body 1, improving the processing effect of the non-woven fabric body 1.

[0041] The collecting component 6 includes a second frame 61, which is fixedly installed on the top of the device side frame 21 near the punching mechanism 3. An installation roller 62 is rotatably installed on the top of the second frame 61, and a winding drum 63 is detachably installed on the outside of the installation roller 62. The waste material generated by the automatic cutting of the nonwoven fabric body 1 is wound around the outside of the winding drums 63 on both sides. The installation roller 62 rotates to drive the winding drum 63 to rotate, and the waste material is synchronously and automatically wound up and collected, further improving the processing effect of the nonwoven fabric body 1.

[0042] The punching mechanism 3 includes a punching top roller 31 and a supporting bottom roller 32, which are distributed vertically. The punching top roller 31 and the supporting bottom roller 32 are rotatably mounted on one side of the middle of the device side frame 21. A first gear 35 is fixedly installed at one end of both the punching top roller 31 and the supporting bottom roller 32. The two first gears 35 are meshed together. A crown gear 36 is fixedly installed at the end of the supporting bottom roller 32 near the first gear 35. A first motor 361 is fixedly installed on the side of the device side frame 21 near the crown gear 36. A second gear 362 is fixedly installed at the drive end of the first motor 361. The second gear 362 and the crown gear 36 are meshed together. By controlling the first motor 361 to start, the second gear 362 drives the crown gear 36 to rotate, thereby driving the supporting bottom roller 32 to rotate. With the meshing connection of the two first gears 35, the punching top roller 31 and the supporting bottom roller 32 are driven to rotate synchronously in opposite directions.

[0043] Multiple heat-sealing rings 33 are evenly distributed and fixedly installed on the outer side of the perforated top roller 31. Each heat-sealing ring 33 has a notch 331. Electric heating elements 34 are fixedly installed at opposite ends of the multiple heat-sealing rings 33 and are fixedly engaged in the perforated top roller 31. An electrical connection 341 is provided in the middle of the perforated top roller 31, and the multiple electric heating elements 34 and the electrical connection 341 are electrically connected. The multiple heat-sealing rings 33 are electrically heated using the electrical connection 341 and the multiple electric heating elements 34. A concave annular groove 321 corresponding to the heat-sealing rings 33 is opened on the outer side of the supporting bottom roller 32. The heat-sealing rings 33 are movably engaged in the corresponding concave annular groove 321. In use, the non-woven fabric body 1, after automatic edge trimming, is passed through the perforated top roller. Roller 31 and support bottom roller 32 are automatically conveyed through the nonwoven fabric body 1. They rotate synchronously in opposite directions with the perforating top roller 31 and support bottom roller 32. Multiple heat-sealing rings 33 at the bottom of the perforating top roller 31 gradually move and engage in the corresponding concave ring grooves 321 at the top of the support bottom roller 32. Thus, the nonwoven fabric body 1 is automatically heat-sealed and perforated by the multiple heat-sealing rings 33, preventing the nonwoven fabric body 1 from being attached to the perforating mechanism 3 and affecting the perforation effect of the nonwoven fabric. Since the heat-sealing rings 33 have notches 331, the waste generated by perforation sticks to the nonwoven fabric body 1, preventing the waste generated by perforation from being attached to the perforating mechanism 3 and affecting the perforation effect of the nonwoven fabric, and facilitating the subsequent collection of waste.

[0044] The hole cleaning mechanism 4 includes a hole cleaning top cylinder 41 and a waste collection support cylinder 42. The hole cleaning top cylinder 41 and the waste collection support cylinder 42 are distributed vertically. The hole cleaning top cylinder 41 and the waste collection support cylinder 42 are rotatably installed on the other side of the middle of the device side frame 21. A third gear 46 is fixedly installed at one end of both the hole cleaning top cylinder 41 and the waste collection support cylinder 42. The two third gears 46 are meshed and connected. By controlling the rotation of the waste collection support cylinder 42, the hole cleaning top cylinder 41 is driven to rotate synchronously in the opposite direction in coordination with the meshing connection of the two third gears 46.

[0045] Multiple evenly distributed ring cutters 43 are fixedly installed on the outer side of the cleaning top cylinder 41. The ring cutters 43 and the heat sealing ring 33 are positioned corresponding to each other. Each side of the cleaning top cylinder 41 near the ring cutters 43 has an exhaust perforation 401. The ring cutters 43, the exhaust perforations 401, and the interior of the cleaning top cylinder 41 are interconnected. The outer side of the waste collection support cylinder 42 has a waste collection perforation 402 corresponding to the ring cutters 43. The waste collection perforation 402 and the interior of the waste collection support cylinder 42 are interconnected. In use, the nonwoven fabric... The main body 1 passes through the cleaning top cylinder 41 and the waste collection support cylinder 42. Through the automatic transmission of the non-woven fabric main body 1, in coordination with the synchronous reverse rotation of the cleaning top cylinder 41 and the waste collection support cylinder 42, multiple ring cutters 43 at the bottom of the cleaning top cylinder 41 gradually move and engage with the corresponding waste collection perforation 402 at the top of the waste collection support cylinder 42. Thus, the waste generated by punching is cut and separated from the non-woven fabric main body 1 by the multiple ring cutters 43 and left in the waste collection perforation 402, thereby realizing the cutting, separation and collection of waste.

[0046] An outer sleeve 45 is movably fitted on the outer side of the cleaning top cylinder 41. The outer sleeve 45 is fixedly installed between the two device side frames 21. The inner wall of the outer sleeve 45 has an inner ring groove 451 corresponding to the ring cutter 43. The ring cutter 43 is movably engaged in the corresponding inner ring groove 451. The bottom of the outer sleeve 45 has an exhaust groove 452. The outer sleeve 45 seals the cleaning top cylinder 41, the ring cutter 43, and the exhaust hole 401 except for the bottom position.

[0047] Both ends of the top cleaning cylinder 41 are fixedly fitted with sealing rotating parts 47. A connector 471 is fixedly installed in the middle of the sealing rotating part 47. The connector 471 is fixedly installed on the outside of the side frame 21 of the device. By setting the sealing rotating parts 47, the connection 471 is fixed without affecting the rotation of the top cleaning cylinder 41. An auxiliary frame 10 is fixedly installed on the side of the side frame 21 near the top cleaning cylinder 41. A duct pump 101 is fixedly installed at the top of the auxiliary frame 10. A three-way pipe 102 is fixedly installed at the output end of the duct pump 101. A connecting pipe 103 is fixedly installed at the end of the through pipe 102. The end of the connecting pipe 103 away from the three-way pipe 102 and the top of the corresponding connector 471 are fixedly installed. While the waste is being cut and separated from the non-woven fabric body 1, the air pump 101 is turned on. The airflow is introduced into the cleaning top cylinder 41 through the three-way pipe 102, the two side connecting pipes 103, and the connector 471, and discharged through the exhaust perforation 401 at the bottom and the ring cutter 43. The waste left in the waste collection perforation 402 is blown into the waste collection support cylinder 42 for automatic collection.

[0048] A cover 421 is slidably attached to the side of the waste collection cylinder 42 away from the third gear 46. The cover 421 is magnetically attached to the waste collection cylinder 42. A cleaning disc 48 is slidably attached to the inner side of the waste collection cylinder 42. A drive screw 481 is rotatably mounted in the middle of the waste collection cylinder 42. The drive screw 481 is threaded through the middle of the cleaning disc 48. One end of the drive screw 481 extends out of the outer side of the waste collection cylinder 42 and is provided with a first bracket 482. A drive shaft 483 is rotatably mounted on the side of the first bracket 482 near the drive screw 481. A locking protrusion 484 is fixedly mounted on one end of the drive shaft 483. The locking protrusion 484 is movably engaged with one end of the drive screw 481. In the initial state, the locking protrusion 484 is disengaged from one end of the drive screw 481 and does not affect the synchronous rotation of the waste collection cylinder 42, the cleaning disc 48, and the drive screw 481. The end of the first bracket 482 away from the drive shaft 483 is provided with Telescopic rod 485 is fixedly installed on the side frame 21 of the device. The drive end of telescopic rod 485 is fixedly installed on the first frame 482. A second motor 486 is fixedly installed on the side of the first frame 482 near the drive shaft 483. The drive end of the second motor 486 is fixedly installed on the drive shaft 483. When a certain amount of waste is automatically collected and needs to be discharged, the rotation of the waste collection support cylinder 42 is stopped and the cover 421 is opened. Then, the telescopic rod 485 is controlled to drive the first frame 482 and the drive shaft 483 to move horizontally, causing the locking protrusion 484 to move and engage with one end of the drive screw 481. Then, the second motor 486 is controlled to drive the drive shaft 483 to control the drive screw 481 to rotate, thereby causing the cleaning disc 48 to slide in the waste collection support cylinder 42. Then, the waste collected in the waste collection support cylinder 42 is automatically discharged through the cover 421 via the cleaning disc 48.

[0049] One end of the support bottom roller 32, the waste collection support cylinder 42, the bottom position pressing roller 51, and the bottom position second guide roller 8 are all fixedly installed with a transmission sprocket 9. The outer sides of the multiple transmission sprockets 9 are meshed with transmission chains 91. A belt pulley transmission group 92 is provided between the end of the top position pressing roller 51 and the end of the corresponding mounting roller 62. The belt pulley transmission group 92 includes two pulleys and a transmission belt that is movably sleeved on the outside of the two pulleys. The two pulleys are respectively fixedly installed at the ends of the corresponding pressing roller 51 and mounting roller 62. They rotate through the support bottom roller 32. With the transmission of multiple transmission sprockets 9 and transmission chains 91, the waste collection support cylinder 42, the bottom position pressing roller 51, and the bottom position second guide roller 8 are driven to rotate synchronously, thereby automatically transferring the nonwoven fabric body 1. With the transmission of the belt pulley transmission group 92, the mounting rollers 62 on both sides are driven to rotate synchronously.

[0050] Working principle: When in use, according to the required cutting width of the nonwoven fabric body 1, the sliding ring seat 52 adjusts the distance between the two cutting blades 53 and tightens them with fastening screws 521. Then, the nonwoven fabric body 1 is passed around the first guide rollers 7 on both sides, and the nonwoven fabric body 1 is passed through the two pressing rollers 51. The edge nonwoven fabric body 1 is passed through the perforated top roller 31 and the supporting bottom roller 32. The nonwoven fabric body 1 is passed through the cleaning top cylinder 41 and the waste collection support cylinder 42. The nonwoven fabric body 1 is passed through the two second guide rollers 8.

[0051] By controlling the start of the first motor 361, the second gear 362 drives the crown gear 36 to rotate, thereby driving the support bottom roller 32 to rotate. With the transmission of multiple transmission sprockets 9 and transmission chains 91, the waste collection support cylinder 42, the bottom position pressing roller 51 and the bottom position second guide roller 8 are driven to rotate synchronously, thereby automatically transferring the nonwoven fabric body 1. With the transmission of the belt pulley transmission group 92, the mounting rollers 62 on both sides are driven to rotate synchronously.

[0052] By driving one of the pressing rollers 51 to rotate, and engaging with the fourth gear 511, the other pressing roller 51 is driven to rotate synchronously in the opposite direction. Thus, the edge of the automatic conveying nonwoven fabric body 1 is automatically cut by the cutting blades 53 on both sides. The waste generated by the automatic cutting of the nonwoven fabric body 1 is wrapped around the outside of the winding drums 63 on both sides. The installation roller 62 rotates to drive the winding drum 63 to rotate, and the waste generated is synchronously and automatically wound up and collected.

[0053] By driving the support bottom roller 32 to rotate, and cooperating with the meshing connection of the two first gears 35, the perforating top roller 31 and the support bottom roller 32 are driven to rotate synchronously in opposite directions. With the automatic transmission of the nonwoven fabric body 1, multiple heat-sealing rings 33 at the bottom position of the perforating top roller 31 gradually move and engage in the corresponding concave ring groove 321 at the top position of the support bottom roller 32. Thus, the nonwoven fabric body 1 is automatically heat-sealed and perforated by the multiple heat-sealing rings 33, preventing the nonwoven fabric body 1 from being attached to the perforating mechanism 3 and affecting the perforation effect of the nonwoven fabric. Since the heat-sealing ring 33 has a notch 331, the waste generated by perforation sticks to the nonwoven fabric body 1, preventing the waste generated by perforation from being attached to the perforating mechanism 3 and affecting the perforation effect of the nonwoven fabric.

[0054] With the synchronous reverse rotation of the top cleaning cylinder 41 and the waste collection support cylinder 42, multiple ring cutters 43 at the bottom of the top cleaning cylinder 41 gradually move and engage with the waste collection perforation 402 at the top of the waste collection support cylinder 42. Thus, the waste generated by punching is cut and separated from the nonwoven fabric body 1 by the multiple ring cutters 43 and left in the waste collection perforation 402, thereby realizing the cutting, separation and collection of waste.

[0055] While the waste material is being cut and separated from the nonwoven fabric body 1, the air pump 101 is turned on. The airflow is introduced into the cleaning top cylinder 41 through the three-way pipe 102, the two side connecting pipes 103, and the connector 471, and discharged through the exhaust hole 401 at the bottom and the ring cutter 43. The waste material left in the waste collection hole 402 is blown into the waste collection support cylinder 42 for automatic collection.

[0056] When a certain amount of waste is automatically collected and needs to be discharged, the rotation of the waste collection support cylinder 42 is stopped and the cover 421 is opened. Then, the control of the opening telescopic rod 485 drives the first frame 482 and the drive shaft 483 to move horizontally, causing the locking protrusion 484 to move and engage with one end of the drive screw 481. Then, the control of the second motor 486 drives the drive shaft 483 to control the drive screw 481 to rotate, thereby causing the cleaning disc 48 to slide in the waste collection support cylinder 42. Then, the waste collected in the waste collection support cylinder 42 is automatically discharged through the cover 421 through the cleaning disc 48.

[0057] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
