[0002] Needle-punched nonwoven fabric is a type of dry-laid nonwoven fabric. It is made by loosening, combing, and laying short fibers into a fiber web, and then reinforcing the fiber web into a cloth through a felting needle. The felting needle has barbs, which repeatedly pierce the fiber web to reinforce the hook-belt fibers to form a needle-punched nonwoven fabric. The non-woven fabric has no distinction between warp and weft, and the fibers of the fabric are messy. The warp and weft properties are not much different. However, before use, the head of the felting needle needs to be polished into a needle tip shape to facilitate the use of the felting needle.

The grinding equipment for producing and processing high-strength non-woven needles according to claim 1, characterized in that: Four threaded through grooves (201) are fixedly arranged on the top of the mounting plate (2), and bolts are rotatably arranged inside the threaded through grooves (201).

10. A method for grinding a grinding device for producing and processing high-strength non-woven needles according to claims 1-9, comprising the following steps: S1: First, place the polished needle inside the arc groove (305), then start the hydraulic cylinder (303), so that the telescopic rod of the hydraulic cylinder (303) drives the connecting block 304 to move backward, so that the connecting block (304) drives the front clamping strip (305) and the hard rubber strip (306) to move backward, so that the hard rubber strip (306) moves to the inside of the arc groove (305), and then the needle is quickly clamped by the hard rubber strip (306) and the arc groove (305); S2: After the needle is clamped, the L-shaped bar (701) is moved upward to stretch the tension spring (702), so that the vertical bar of the L-shaped bar (701) moves out from the inside of the rack (503), and the fixation of the T-shaped plate (501) and the grinder (6) is released. Then, the grinding belt (605) is driven forward by the C-shaped plate (601) to contact the side of the needle, and the needle can be quickly grinded by starting the motor (603); S3: While the needle is being sharpened, the rotating shaft of the motor (603) drives the active bevel gear (606) to rotate, so that the active bevel gear (606) drives the driven bevel gear (6011) and the reciprocating screw (6010) to rotate. At the same time, the moving block (608) is limited by the limiting groove (607), so that the reciprocating screw 6010 drives the moving block (608) to move back and forth inside the limiting groove (607), thereby driving the T-shaped block (6012) and the cleaning brush (6013) to move back and forth on the upper side of the mounting plate (2), thereby quickly cleaning the iron filings and other dust on the upper side of the mounting plate (2).
