The second rotating roller 226 and the first rotating roller 225 are relatively spaced apart in the height direction, and the second rotating roller 226 is located below the first rotating roller 225.

[0042] In order to adjust the distance between the first rotating roller 225 and the second rotating roller 226 in the height direction, in this embodiment, a pair of second support rods 221 are fixedly connected to the right end of the support frame 1. The front ends of the pair of second support rods 221 are rotatably connected to a slide rod 222. The slide rod 222 extends in the height direction, and the position of the slide rod 222 relative to the pair of second support rods 221 remains unchanged in the height direction.

[0043] In the embodiment of the present utility model, when the device starts to adjust the distance, the threaded rod 215 of the position adjustment device 21 of the position adjustment component 2 moves in the support block 214, and the movement of the threaded rod 215 drives the slide plate 213 to move along the chute 212;

[0044] The movement of the slide plate 213 drives the support frame 224 of the drive device 22 to move, and the movement of the support frame 224 drives the first rotating roller 225 and the conical gear 227 at the upper end to move to complete the adjustment of the distance between the first rotating roller 225 and the second rotating roller 226;

[0045] At the same time, the movement of the slide plate 213 drives the first support rod 216 to move synchronously, and the movement of the first support rod 216 drives the conical gear 223 to move on the slide rod 222.

[0046] When the device is ready for cutting, an external power device is used to drive the slide rod 222 to rotate on the second support rod 221. The rotation of the slide rod 222 drives the conical gear 223 and the conical gear 228 to rotate. The rotation of the conical gear 223 and the conical gear 228 drives the conical gear 227 to rotate. The rotation of the conical gear 227 drives the first rotating roller 225 and the second rotating roller 226 to rotate. The rotation of the first rotating roller 225 drives the cutting component 3 to rotate. The cotton strip passes through the space between the rotating second rotating roller 226 and the cutting component 3 to complete the extrusion cutting. The function of the second support plate 229 is to support the second rotating roller 226.

[0047] The distance between the first rotating roller 225 and the second rotating roller 226 is adjusted by rotating the threaded rod 215, and then the distance between the cutting component 3 and the second rotating roller 226 is adjusted, so that holes can be punched in cotton strips of different thicknesses. At the same time, during the adjustment process, the first rotating roller 225 and the second rotating roller 226 can be slowly rotated to ensure that the distance between the devices after adjustment is appropriate and will not cause the distance adjustment to be too small and damage the cutting tool, or the distance adjustment to be too large and unable to cut the cotton strip.

[0048] A cutting component 3 for cutting cotton strips is installed on the position adjustment component 2.

[0049] The cutting component 3 includes a cutting device 31 and a locking device 32, and the first rotating roller 225 is connected to the cutting device 31 and the locking device 32.

[0050] The cutting device 31 includes a first limiting sliding groove 311, a cutting roller 312, a limiting block 313, a cutting tool block 314, a first stop block 315 and a threaded block 316.

[0051] A first limiting sliding groove 311 is formed on the circumferential surface of the first rotating roller 225. The first limiting sliding groove 311 extends along the axial direction of the first rotating roller 225, and the left end of the first limiting sliding groove 311 penetrates the left end face of the first rotating roller 225 along the axial direction. The right end of the first limiting sliding groove 311 is a sealing end. A cutting roller 312 is sleeved on the outer wall of the first rotating roller 225. A limiting block 313 is fixedly connected to the inner wall of the cutting roller 312. The limiting block 313 extends along the axial direction of the cutting roller 312. The limiting block 313 is slidably connected in the first limiting sliding groove 311. That is, the first rotating roller 225 and the cutting roller 312 are sleeved with each other and are circumferentially limited and matched to prevent relative rotation between the two. A cutting tool block 314 is fixedly connected to the outer wall of the cutting roller 312.

A threaded block 316 is threadedly connected to the left end of the first rotating roller 225. With such a setting, the relative movement of the first rotating roller 225 and the cutting roller 312 in the axial direction can be restricted.

[0053] Specifically, the locking device 32 includes a second limiting chute 321, a second stopper 322, and a bolt 323. The second limiting chute 321 is provided on each of the pair of support frames 224.

A second stopper 322 is slidably connected in the second limiting chute 321. The second stopper 322 is in contact connection with the first rotating roller 225, and the second stopper 322 is fixedly connected to the support frame 224 by a bolt 323. With this setting, it is convenient to respectively pass the two ends of the first rotating roller 225 through the two second limiting chutes 321, that is, the first rotating roller 225 is installed on the support frame 224 through the locking device 32.

[0054] In the embodiment of the present utility model, when the device starts to be installed, the cutting roller 312 and the limiting block 313 of the cutting device 31 of the cutting component 3 are slid along the first limiting chute 311 onto the first rotating roller 225. The first stopper 315 is sleeved on the first rotating roller 225 and the first stopper 315 is abutted against the end face of the cutting roller 312. Then, the first stopper 315 and the cutting roller 312 are pressed tightly by rotating the threaded block 316 to prevent the cutting roller 312 from falling off.

[0055] When the first rotating roller 225 is installed on the support frame 224, the second stopper 322 of the locking device 32 is slid into the support frame 224 along the second limiting chute 321 to abut against the first rotating roller 225, and the second stopper 322 and the support frame 224 are locked by rotating the bolt 323.

[0056] When the device starts punching, the first rotating roller 225 drives the first limiting chute 311 to rotate. The first limiting chute 311 drives the limiting block 313 and the cutting roller 312 to rotate. The cutting roller 312 drives the cutting blade block 314 to rotate. The rotating cutting blade block 314 contacts and presses against the lower second rotating roller 226 to cut holes in the shape of the cutting blade block 314 on the cotton cloth.

[0057] The device of this solution can install and replace cutting rollers 312 of different models to meet the cutting requirements of cotton strips of different shapes and specifications, improving the adaptability of the product.
