Description

An edge-gathering device for spunlace nonwoven fabric processing Technical Field

[0001] This utility model relates to an edge-gathering device, specifically an edge-gathering device for spunlace nonwoven fabric processing, belonging to the field of spunlace nonwoven fabric processing technology. Background Technology

[0002] Spunlace nonwoven fabric is a type of nonwoven fabric formed by spraying high-pressure micro-jet water onto a fiber web, causing the fibers to entangle and solidify into a fabric. This process does not require any adhesives or thermoplastic materials, retains the original softness of the fibers, and features good hand feel, high strength, good water absorption, and excellent breathability. It is widely used in medical materials, hygiene products, wiping cloths, and clothing linings. Edge finishing is a process in the production of spunlace nonwoven fabric that treats the edges of the fabric to prevent the fibers from not being fully entangled at the edges.

[0003] In existing technologies, a rotary cutter is commonly used for edge finishing. Rotary cutter edge finishing utilizes a high-speed rotating circular cutter to cut and finish the edges of the spunlace nonwoven fabric. A motor drives the rotary cutter shaft, causing the circular blade mounted on the shaft to rotate at high speed. The nonwoven fabric passes uniformly under the rotary cutter under the conveyor, cutting off the excess part of the nonwoven fabric edge, thereby achieving edge finishing.

[0004] In practical applications, it has been found that due to the constant friction and cutting between the rotating blade and the nonwoven fabric at high speed, the blade wears relatively quickly, requiring regular blade replacement, which increases production costs and equipment maintenance workload. Therefore, this paper proposes an edge-trimming device for spunlace nonwoven fabric processing. Summary of the Invention

[0005] This invention proposes an edge-gathering device for spunlace nonwoven fabric processing, which can sharpen the blade without disassembling it, thus extending the blade's service life and reducing the frequency of replacement.

[0006] This utility model is achieved through the following technical solution: a spunlace nonwoven fabric processing edge-gathering device, including a bracket, the bracket including a mounting plate, the bracket including a fixing plate, the fixing plate having mounting holes, and by installing bolts in the mounting holes of the fixing plate, the stability of the device can be improved.

[0007] It also includes a lead screw module, which is mounted on a mounting plate. The lead screw module includes a base, which is fixed on the mounting plate. A servo motor is fixed on the base, and a bidirectional lead screw is fixed at the output end of the servo motor. A guide rail is fixed on the base, and two symmetrical ball sliders are mounted on the bidirectional lead screw. The ball sliders are slidably connected to the guide rail.

[0008] Specifically, the start of the servo motor can drive the bidirectional lead screw to rotate, and the rotation of the bidirectional lead screw can drive the two ball sliders to move towards each other. In turn, the two ball sliders drive the upright plate, drive motor and cutter to move, so as to adjust the edge size.

A drive motor is mounted on the vertical plate, and a cutter is mounted on the output end of the drive motor. A lifting device is installed between the vertical plate and the ball bearing slider. The lifting device is used to adjust the height of the vertical plate, the drive motor, and the cutter, so that the device can be used for spunlace nonwoven fabric conveying devices of different heights.

[0010] It also includes a grinding component, which is disposed on the edge finishing component. The grinding component includes a protective cover and a grinding block. The grinding block is disposed on the protective cover. A sliding rod is slidably connected to the protective cover. The sliding rod is fixed to the grinding block. A driving component is disposed between the grinding block and the protective cover. The driving component is a spring.

[0024] Please refer to Figures 1 to 4. The present invention proposes the following implementation scheme: a spunlace nonwoven fabric processing edge-gathering device, including a bracket 1, the bracket 1 including a mounting plate 101, the bracket 1 also including a fixing plate 102, the fixing plate 102 having mounting holes, and by installing bolts in the mounting holes of the fixing plate 102, the stability of the device can be improved.

[0025] Please refer to Figures 1 and 2 for details. The system also includes a lead screw module 2, which is mounted on the mounting plate 101. The lead screw module 2 includes a base 201, which is fixed on the mounting plate 101. A servo motor 202 is fixed on the base 201.

[0026] The output end of the servo motor 202 is fixed with a bidirectional lead screw 203, and a guide rail 205 is fixed on the base 201. Two symmetrical ball sliders 204 are installed on the bidirectional lead screw 203, and the ball sliders 204 are slidably connected to the guide rail 205.

[0027] Specifically, the start of the servo motor 202 can drive the bidirectional lead screw 203 to rotate. The rotation of the bidirectional lead screw 203 can drive the two ball sliders 204 to move towards each other. In turn, the two ball sliders 204 drive the upright plate 301, the drive motor 302, and the cutter 303 to move, thereby realizing the adjustment of the edge trimming size.

[0028] Please refer to Figures 2, 3 and 4 for details. The system also includes an edge trimming component 3, which is mounted on the lead screw module 2. The edge trimming component 3 includes a vertical plate 301, which is fixed on the ball slider 204. A drive motor 302 is mounted on the vertical plate 301.

[0029] A cutter 303 is installed at the output end of the drive motor 302. A lifting device is installed between the upright plate 301 and the ball block slider 204. The lifting device is used to adjust the height of the upright plate 301, the drive motor 302, and the cutter 303, so that the device can be used for spunlace nonwoven fabric conveying devices of different heights.

[0030] Please refer to Figures 3 and 4 for details. The system also includes a grinding component 4, which is mounted on the edge finishing component 3. The grinding component 4 includes a protective cover 401 and a grinding block 402. The grinding block 402 is mounted on the protective cover 401. A sliding rod 403 is slidably connected to the protective cover 401. The sliding rod 403 is fixed to the grinding block 402. A driving component 404 is provided between the grinding block 402 and the protective cover 401. The driving component 404 is a spring.

[0031] A connecting plate 405 is fixed on the slide rod 403, a rotating shaft 406 is rotatably connected to the connecting plate 405, a pull block 409 is fixed on the rotating shaft 406, a fixing ear 410 is fixed on the protective cover 401, and the protective cover 401 is fixed to the upright plate 301 by the fixing ear 410 and bolts.

[0032] An adjusting plate 407 is fixed on the rotating shaft 406, and a limiting block 408 is fixed on the protective cover 401. The limiting block 408 is used to limit the adjusting plate 407. After the adjusting plate 407 moves out of the limiting block 408, the grinding block 402 will abut against the cutter 303 under the elastic force of the driving component 404.

[0033] Working principle: When finishing the edge of the spunlace nonwoven fabric, the servo motor 202 is started first. The start of the servo motor 202 drives the bidirectional lead screw 203 to rotate. The rotation of the bidirectional lead screw 203 will cause the two ball sliders 204 to move towards each other, thereby adjusting the size of the edge to be finished. Then, the drive motor 302 is started. The drive motor 302 drives the cutter 303 to rotate. The nonwoven fabric passes through the cutter 303 at a uniform speed under the drive of the conveying device, and the excess part of the nonwoven fabric edge is cut off, thereby achieving edge finishing.

[0034] After the cutter 303 becomes dull, the pull block 409 pulls the rotating shaft 406. Then, the pull block 409 is rotated, and the rotating shaft 406 and the adjusting plate 407 will rotate along with it until they move out of the range of the limit block 408. At this time, under the drive of the drive component 404, the sharpening block 402 will press against the cutter 303, and then the rotation of the cutter 303 will cause the sharpening block 402 to sharpen it. This device can sharpen the cutter 303 without disassembling it, thus extending the service life of the cutter 303 and reducing the replacement frequency.
