Preparation process of table tennis bat rubber

Abstract

The invention discloses a preparation process of table tennis bat rubber, which comprises the following steps: mixing natural rubber and synthetic rubber, then adding auxiliary materials for mixing, adding a vulcanization activator and an anti-aging agent for mixing, carrying out rubber discharging, and finally adding a vulcanization accelerator and sulfur for mixing, so as to prepare the rubber which is well balanced in elasticity and hardness. The preparation device is simple in structure, cutting, gluing and pressing are integrated, a cutting knife is matched with a cutting table and an annular groove in the shape of the cutting knife, cutting is completed at a time, the peripheral contour of the cut rubber is smooth, and the cutting quality is improved; and a pressing mechanism is matched with a gluing mechanism and a cutting mechanism, certain pressure is applied, pressure maintaining can be conducted for a certain time according to needs, the gluing mechanism conducts quantitative gluing, and the pasting quality is improved; the preparation device is simple in structure, the cutting and pasting quality and efficiency of the table tennis bat rubber can be effectively improved, manual operation and the workload are reduced, and the technical requirement for operators is lowered.

Description

technical field [0001] The invention belongs to the technical field of table tennis racket rubber, and in particular relates to a preparation process and a preparation device of table tennis racket rubber. Background technique [0002] Table tennis, known as China's "national ball", is also a popular ball game in the world, and the quality of table tennis rackets has a certain impact on the performance of athletes; table tennis rackets are composed of three parts: the bottom plate, rubber and sponge. The reasonable collocation determines the quality of a racket, especially the quality of the table tennis racket rubber. The hardness and elasticity of the rubber are important indicators of the rubber. The elasticity or hardness of many rubbers on the market cannot meet the demand; in addition to the rubber preparation process, the preparation device of the table tennis racket is also An important factor affecting the quality of table tennis rackets. Existing table tennis racke...

[0002] Table tennis, known as China's "national ball", is also a popular ball game in the world, and the quality of table tennis rackets has a certain impact on the performance of athletes; table tennis rackets are composed of three parts: the bottom plate, rubber and sponge. The reasonable collocation determines the quality of a racket, especially the quality of the table tennis racket rubber. The hardness and elasticity of the rubber are important indicators of the rubber. The elasticity or hardness of many rubbers on the market cannot meet the demand; in addition to the rubber preparation process, the preparation device of the table tennis racket is also An important factor affecting the quality of table tennis rackets. Existing table tennis rackets have the phenomenon that the rubber falls off and the peripheral contour of the rubber is not smooth. Therefore, rubber cutting and gluing and pressing are the key links in the production. A process of the existing preparation device requires an independent The device is complicated to operate and takes up space. The connection of each process requires manual operation. The technical requirements for manual operation are high, the workload is large, and there are many human factors, which make the product quality different.
