[0014] The present invention provides a non-woven fabric high-speed slitting machine, which has the following beneficial effects:

[0015] (1) The invention drives the two cutters to slide on the reciprocating screw by rotating the reciprocating screw. The two cutters slide to continuously adjust the distance between them, ensuring that the non-woven fabric reaches the required size after being cut. The precise cutter spacing can maximize the use of materials, reduce waste generated during the cutting process, and improve the utilization rate of raw materials. The cutting area is isolated and protected by the sliding guard plate, which effectively prevents the operator from accidentally contacting the knife, reduces the risk of accidents, and protects the safety of the operator. At the same time, it can prevent non-woven fabric debris and other materials from splashing, help keep the working environment clean, and reduce cleaning work.

[0016] (2) The invention reduces the tension of the non-woven fabric by sliding the pressure column into contact with the non-woven fabric and continuously pressing the non-woven fabric downward, thereby ensuring the stability of the non-woven fabric and reducing the displacement of the material during the cutting process, thereby improving the precision and consistency of the cutting and preventing the non-woven fabric from being torn or displaced due to excessive tension. The rotation of the rotating rod drives the long rod to start rotating, and the rotation of the long rod smoothes the non-woven fabric, ensuring that the non-woven fabric is in a flat state before cutting, so as to obtain a cleaner cutting edge, improve the overall quality of the final product, and prevent tearing or damage caused by wrinkles during the cutting process.

[0017] (3) The invention scrapes off the non-woven fabric scraps and other materials on the surface of the filter plate by moving the scraper rod to prevent them from accumulating inside the machine, maintain smooth ventilation, reduce the risk of equipment failure, and extend the service life of the equipment. The baffle plate is moved to open the collection drawer, so that the scraper rod scrapes the non-woven fabric scraps and other materials into the collection drawer, ensuring that the non-woven fabric scraps and other materials can be completely collected and will not accumulate inside the equipment, keeping the working area clean and tidy, and improving the comfort and safety of operation. By pulling out the collection drawer and then properly disposing of the non-woven fabric scraps and other materials, subsequent resource utilization, such as reprocessing or recycling, is ensured, reducing material waste.

The other end of the reciprocating screw 14 is rotatably mounted on the end of the fixed block 16 away from the sleeve 13, the cutter 15 is slidably mounted on the circumferential surface of the reciprocating screw 14, and the guard plate 18 is fixedly mounted on the circumferential surface of the sleeve 13. The reciprocating screw 14 rotates to drive the two cutters 15 to start sliding on the reciprocating screw 14. The two cutters 15 slide and continuously adjust the distance between them to ensure that the non-woven fabric reaches the required size after being cut. The precise spacing of the cutters 15 can maximize the use of materials, reduce waste generated during the cutting process, and improve the utilization rate of raw materials.

[0022] The cutter 15 is threadedly connected to the reciprocating screw 14, and the turning handle 17 is in contact with the reciprocating screw 14. The threaded connection ensures that the reciprocating screw 14 can drive the cutter 15 to slide when it rotates, and the turning handle 17 is in contact with the reciprocating screw 14 to ensure that the turning handle 17 can drive the reciprocating screw 14 to rotate when it rotates.

[0030] When the present embodiment is working: when the guard plate 18 slides, the slider 192 is driven to slide, and the sliding of the slider 192 drives the pressure column 193 to slide, and the pressure column 193 slides to contact the non-woven fabric and continuously presses the non-woven fabric downward to reduce the tension of the non-woven fabric, thereby ensuring the stability of the non-woven fabric and reducing the displacement of the material during the cutting process, thereby improving the cutting accuracy and consistency, and preventing the non-woven fabric from being torn or displaced due to excessive tension; when the slider 192 slides, the fixed rod 194 is driven to slide, and the sliding of the fixed rod 194 drives the rotating rod 195 to slide, and the sliding of the rotating rod 195 drives the long rod 196 to slide.

The push block 206 moves and pushes the inclined plane block 209 to start moving. The inclined plane block 209 moves and drives the baffle plate 208 to start moving. The baffle plate 208 moves to open the collecting drawer 207, so that the scraper rod 205 scrapes the non-woven fabric scraps and other materials into the collecting drawer 207, ensuring that the non-woven fabric scraps and other materials can be completely collected and will not accumulate inside the equipment, keeping the working area clean and tidy, and improving the comfort and safety of operation. After the collecting drawer 207 is full, the collecting drawer 207 can be pulled, the collecting drawer 207 can be pulled out, and then the non-woven fabric scraps and other materials can be properly handled to ensure subsequent resource utilization, such as reprocessing or recycling, and reduce material waste.
