Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric cutting technology for processing activated carbon fiber dressings, and in particular to a nonwoven fabric cutting device for processing activated carbon fiber dressings. Background Art

[0002] Nonwoven fabric refers to a fabric-like product made from chemical fibers as basic raw materials, bonded together chemically (or thermally). Because it is not woven, it is also called nonwoven cloth. It is made by directly using polymer chips, short fibers, or filaments to form a web through airflow or mechanical means, then reinforcing it through hydroentangling, needle punching, or thermal rolling, and finally finishing processes to form a non-woven fabric. Due to its superior performance, it is widely used in the processing and manufacturing industry. In the processing of activated carbon fiber dressings, equipment is needed to cut the nonwoven fabric.

[0003] Traditional nonwoven fabric cutting devices can only cut nonwoven fabrics of constant size when cutting and trimming, which limits the cutting process. At the same time, nonwoven fabrics are prone to loosening and wrinkling when moving, resulting in uneven cuts and affecting product quality. Therefore, they are not convenient to meet customers' nonwoven fabric cutting needs.

[0004] Therefore, those skilled in the art have provided a nonwoven fabric shearing device for processing activated carbon fiber dressings to solve the problems mentioned in the background art. Utility Model Content

[0039] Example 2:

[0040] Reference Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 7A positioning mechanism 3 is provided on the top of the base 1. The positioning mechanism 3 includes a 301, which is fixedly connected to the base 1. A second servo motor 302 is fixedly installed on the left side of the inner cavity of the 301. A first gear 303 is fixedly installed on the output shaft of the second servo motor 302. A first lifting threaded rod 305 is provided on the left side of the inner cavity of the 301. A second gear 304 is fixedly installed on the bottom surface of the first lifting threaded rod 305. The first gear 303 and the second gear 304 mesh with each other.

A first rotating shaft 307 is fixedly installed on the right side of the surface of the first lifting threaded sleeve 306. A first rubber roller 308 is fixedly installed on the surface of the first rotating shaft 307. The first rotating shaft 307 is located away from the first lifting threaded rod 305. One end of the threaded sleeve 306 is fixedly connected to a second lifting threaded sleeve 309. The inner cavity of the second lifting threaded sleeve 309 is threadedly connected to a second lifting threaded rod 310. Both sides of the inner cavity of 301 are provided with mounting grooves 313. Both ends of the first lifting threaded rod 305 and the second lifting threaded rod 310 are rotatably connected to the mounting grooves 313 through bearings. A slide is provided on one side of the inner cavity of the mounting groove 313. A sliding plate is fixedly installed on one side of the first lifting threaded sleeve 306 and the second lifting threaded sleeve 309, and the slide is slidably connected to the sliding plate. The front and rear positions of the inner cavity of 301 are rotatably connected to a second rotating shaft 311 through bearings. A second rubber roller 312 is fixedly installed on the surface of the second rotating shaft 311. An anti-slip pad is provided at the bottom of the base 1, and the anti-slip pad is made of rubber.

[0041] In this embodiment: by setting a positioning mechanism 3, the second gear 304 can be rotated by turning on the second servo motor 302, causing the first lifting threaded sleeve 306 to move up and down, thereby driving the first rubber roller 308 to move, stretching the non-woven fabric, making the non-woven fabric taut, and facilitating positioning during cutting. The mounting groove 313 can protect the equipment components and save installation space. The bearing can position the first lifting threaded rod 305 and the second lifting threaded rod 310, reducing wear on the inner cavity of the mounting groove 313. The slide rail and slide plate can guide and limit the movement of the first lifting threaded sleeve 306 and the second lifting threaded sleeve 309. The two second rubber rollers 312 can cooperate with the first rubber roller 308 to position the non-woven fabric, facilitating cutting. The anti-slip pad can increase the friction between the equipment and the ground, enhancing the stability of the equipment.

[0042] The implementation principle of this utility model is as follows: In use, firstly, the second servo motor 302 is turned on. The second servo motor 302 drives the first gear 303 to rotate, which in turn drives the second gear 304 to rotate. The rotation of the second gear 304 drives the first lifting threaded rod 305 to rotate, thereby causing the first lifting threaded sleeve 306 to move upward along the first lifting threaded rod 305. The first lifting threaded sleeve 306 can drive the first rotating shaft 307 to move upward, thereby causing the second lifting threaded sleeve 309 to move upward along the second lifting threaded rod 310, causing the first rubber roller 308 to rise above the two second rubber rollers 312, allowing the non-woven fabric to pass through the top of the two second rubber rollers 312. Then, the second servo motor 302 is turned on again to cause the first gear 303 to rotate in the opposite direction. The second gear 304 is reversed, causing the first lifting threaded sleeve 306 to move downwards along the first lifting threaded rod 305. This moves the first rubber roller 308 downwards to between the two second rubber rollers 312, stretching and tightening the nonwoven fabric to achieve positioning and prevent deviation. The electric cylinder 201 is then raised, and the first servo motor 203 is activated to rotate the positive and negative threaded rods 204. The rotation of the positive and negative threaded rods 204 causes the two threaded sleeves 205 to move away from or closer to each other along the positive and negative threaded rods 204. The distance between the two threaded sleeves 205 is adjusted to the required cutting width. The nonwoven fabric is then passed between the two electric cylinders 201, and the electric cylinders 201 are lowered so that the cutting blade 208 contacts the nonwoven fabric. At the same time, the two cutting motors 207 are activated to cut the nonwoven fabric.

[0043] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
