[0002] As is known to all, a zipper is a component that temporarily combines two pieces of fabric together, and is commonly found in clothing, suitcases, handbags, tents, sleeping bags, etc.; a zipper head is usually cast by a mold, and therefore the burrs on the zipper head need to be cleaned after molding, and the prior art uses a method of setting an active roller and a driven roller to drive a grinding belt to rotate to grind the burrs on the zipper head; a patent with a publication number of CN217668553U disclosed in the China Patent Network discloses a deburring device for zipper production and processing, which belongs to the field of zipper production technology, and includes a base, a first cylinder is installed at one end of the top of the base, a mounting plate is installed at the output end of the first cylinder, a fixed splint is fixed at the bottom of the mounting plate away from the first cylinder, a second cylinder is installed at the top of the mounting plate close to the fixed splint, a sliding splint is installed at the output end of the second cylinder, and a rotating mechanism is provided between the fixed splint and the sliding splint. The utility model discloses a grinding mechanism composed of a slide groove on the top of the base, a slider, a return spring, a grinding motor, an active roller, a driven roller and a grinding belt. In the process of the slider squeezing the grinding belt, the grinding belt can be deformed and better fit to the outer side of the slider, thereby improving the grinding effect and increasing the grinding area in the single-sided grinding process, which is more practical.

[0003] However, the zipper deburring device of the prior art still has the following disadvantages when in use: First, since the slider arranged at the bottom of the driven roller is connected to the slide groove by a return spring, the driven roller will swing back and forth when in use, which will cause insufficient tensioning force of the grinding belt on the active roller and the driven roller, which can easily cause low grinding efficiency and the problem of the grinding belt falling off; Second, since the grinding belt is a consumable, the grinding belt needs to be replaced regularly, and the zipper deburring device of the prior art does not have the function of convenient disassembly and assembly of the grinding belt, so that the convenience of the zipper deburring device when in use still needs to be improved; for this reason, we propose a zipper deburring device.
