Description

Polishing equipment for upper and lower stops of zipper Technical Field The utility model relates to the field of equipment for zipper accessories, in particular to polishing equipment for upper and lower stops of a zipper. Background In the zipper production process, the upper and lower stops of the zipper are used as key components, and the surface finish of the upper and lower stops directly influences the overall quality, service life and aesthetic appearance of the zipper. Therefore, polishing treatment is an indispensable procedure for the upper and lower stops of the zipper, and defects such as surface burrs and oxide layers can be removed through polishing, so that the precision and texture of the product are improved. At present, a roller type structure is mainly adopted by polishing equipment for upper and lower stops of a zipper, the working principle of the polishing equipment is that the upper and lower stops of the zipper to be polished are put into a roller, friction and collision are generated between workpieces of the upper and lower stops of the zipper and between the workpieces and the inner wall of the roller through rotation of the roller, and therefore polishing effect is achieved. However, when applied to small-sized, lightweight, and easily piled workpieces such as zippers, conventional roller polishers have significant drawbacks: The cylinder inner wall is comparatively smooth generally or only sets up simple arch, and at the cylinder rotation in-process, the stirring and stirring effect of work piece are not good, and rotatory in-process work piece and abrasive material are easy to adhere to the section of thick bamboo wall and slide under centrifugal force effect, and inside material is difficult to fully turn, and work piece pile up, the inhomogeneous problem of polishing easily appears, leads to part polishing not enough, and material distribution is uneven, has the polishing dead angle, influences product quality's uniformity. The conventional stirring rod, such as a straight bar or a spiral, is fixed on the central shaft in many cases, and the movement track of the stirring rod is single. When the roller rotates unidirectionally, collision randomness among workpieces and between the workpieces and the abrasive is poor, relative motion intensity and frequency among the workpieces are low, disturbance intensity is insufficient, so that the motion trail of the workpieces in the roller is simple, the workpieces cannot fully contact with polishing media, and further polishing effect is affected. The existing equipment lacks effective guidance to the axial movement of the material along the roller, the axial movement is insufficient, the workpiece is easy to gather in a local area, the axial dispersion capability is weak, the polishing consistency of batch workpieces is poor, the polishing uniformity is insufficient, and the omnibearing uniform polishing is difficult to realize. Disclosure of utility model The utility model aims to overcome the defects of the prior art, and provides polishing equipment for a zipper upper and lower stop, which solves the problems of uneven polishing, single stirring track, weak axial dispersion capability and the like. The technical scheme includes that the device comprises a roller, a central shaft penetrating the roller and a driving piece, wherein the roller is connected with the driving piece to realize axial reciprocating rotation around the roller, a main body of the roller is of a prismatic hollow structure, a plurality of stirring columns extending towards the center of the roller are arranged on each inner wall surface of the main body of the roller at intervals along the axial direction of the roller, at least two groups of stirring rollers extend out of the central shaft in the radial direction of the central shaft, each group of stirring rollers are arranged at intervals along the axial direction of the central shaft, the stirring rollers are uniformly arranged relatively in the circumferential direction of the central shaft, and when the roller rotates, the stirring columns rotate along with the roller and pass through intervals among the stirring columns. According to the technical scheme, the stirring roller passes through the gap of the stirring column to generate a space shearing effect, a dynamic cross grid structure is formed when the roller rotates reciprocally, so that the stirring column can stir the upper and lower ends of the zipper fully and effectively along with the rotation of the stirring roller, the motion track of the material is more complex and variable, the collision randomness among workpieces and between the workpieces and abrasive materials is strong, the frequency and the intensity of turning of the upper and lower ends of the zipper are increased, the disturbance intensity is improved, meanwhile, the inner wall of the roller is not a cylindrical structure any more, the upper and lower ends of the zipper are forc
