Description

Technical Field

[0001] The utility model relates to the technical field of table tennis racket grinding devices, in particular to a grinding device for producing table tennis rackets. Background Art

[0002] In the prior art, a table tennis racket is divided into three parts: a base plate, a rubber and a sponge. The reasonable combination of the three determines the quality of a racket. The number of base plate layers usually ranges from one to seven layers, and a five-layer plate is the most popular. Theoretically, a five-layer plate refers to a three-layer core plate in the middle and a layer of plate on each side. During the production process of a table tennis racket, it is necessary to grind the arc angles between the grip and the base plate and the sides of the base plate to improve the comfort of the user when holding the racket and the smoothness of the edge of the table tennis base plate. Before making the plate, it is necessary to go through a grinding and sanding step. Grinding and sanding makes the side of the core plate smooth and the thickness uniform, and removes burrs on the edge of the base plate for easy production. Post-grinding is required, but most of them are basically manually polished or semi-automatically polished, and there are problems such as uneven polishing, irregular polishing, and appearance deformation, poor quality, labor consumption, and high cost. Workers perform long-term manual polishing in a poor working environment, inhale a large amount of dust, and are prone to dust occupational diseases.

[0003] The Chinese utility model patent with application number: 202222094048.6 discloses an automatic polishing device for a table tennis racket, which consists of a main frame assembly, a swing angle sand rack assembly, a working slide assembly, a suction cup feeding assembly and a racket positioning seat assembly. The upper left side of the main frame assembly is a swing angle sand rack assembly, and the swing angle sand rack assembly includes an X-axis guide rail, and the X-axis guide rail is provided with an X-axis ball screw that cooperates with it. The X-axis ball screw and the X-axis guide rail are provided with a sand rack slide, one end of the X-axis ball screw is connected to the X-axis servo motor, and a fixed sand rack is assembled on the side of the sand rack slide, a swing angle cylinder is installed on the upper part of the fixed sand rack, and the bottom of the fixed sand rack is a swing angle sand rack. However, this type of automatic table tennis racket polishing device can only perform polishing operations on one group of table tennis rackets, and cannot perform polishing operations on multiple groups of table tennis rackets at the same time. Its processing efficiency is low and cannot meet the large-scale production and processing needs of table tennis rackets. In addition, it does not have a conveying device and cannot automatically convey the table tennis rackets. Utility Model Content
