Problems solved by technology

[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.

Embodiment 1

[0033] A preparation process for table tennis racket rubber, comprising the following steps;

[0034](1) After initially mixing 60 parts by weight of natural rubber, 15 parts by weight of trans-1,4-polyisoprene rubber and 25 parts by weight of butadiene rubber, knead for 3 minutes at 120 ° C on a rubber mixer Add 3 parts by weight of coloring agent while mixing; Then add 12 parts by weight of polymethyl methacrylate, 18 parts by weight of polyvinylimidazole, and 12 parts by weight of polyacrylonitrile and mix for 3 minutes at 120 ° C on the rubber mixer. Then add 1 part by weight of 2,2,4-trimethyl-1,2-dihydroquinoline polymer and 7 parts by weight of zinc carbonate and mix for 3 minutes, then debinding at 90-110°C, and then add 0.8 parts by weight 2,2'-dithiodibenzothiazole and 0.8 parts by weight of sulfur were mixed at 80-100°C for 3 minutes to obtain a compound compound;

[0035] (2) Add the mixed rubber material obtained in step (1) to the calender to calender the sheet....

Embodiment 2

[0038] A preparation device for the preparation process of table tennis racket rubber, including a rubber mixing machine, a calender and a table tennis racket assembly machine, the table tennis racket assembly machine includes a box body 1, a support frame 9 is provided below the box body 1, and the rubber is unwound The roller is placed behind the box body 1, and the rubber winding roller is placed in front of the box body 1. The rear side and the front side of the box body 1 are respectively equipped with a rubber inlet and a rubber outlet. Both sides of the rubber inlet are provided with supporting rollers.

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.
