Description

Technical Field

[0001] The utility model relates to the technical field of table tennis racket production equipment, in particular to a rubber cutting device for table tennis rackets. Background Art

[0002] In the prior art, table tennis rackets are essential equipment for table tennis. Athletes with higher technical levels have higher requirements for table tennis rackets. Table tennis rackets are mainly composed of a base plate and rubber. Under the premise that the rubber and the base plate are certain, the degree of coordination between the rubber and the base plate determines the quality of the racket. How to stick the rubber to the base plate with high quality is a very difficult task. Even for professional athletes with many years of experience in rubber sticking, the quality of the rubber stuck each time is not exactly the same, because manual sticking cannot guarantee the consistency of key links such as the thickness and uniformity of the glue coating, the waiting time after gluing, the size and uniformity of the pressure during pressing, and after sticking, the excess rubber must be cut off with scissors. There are two ways to trim the excess rubber stuck on the outer edge of the base plate of the table tennis racket. One is a manual method using scissors, utility knives, scalpels and other knives, and the other is a manual method using scissors, utility knives, scalpels and other knives. The mechanical method is to drive the cutter to cut the excess rubber on the racket by a motor. However, the manual method has the following defects: it is time-consuming and labor-intensive, and the efficiency is low; the scrap rate is high, and the production cost is increased; the cutter is easy to scratch the edge of the racket bottom plate during movement, which affects the performance of the athlete's technical level. The mechanical method also has many disadvantages: the installation of the motor makes the structure complex and bulky, and also increases the manufacturing cost; because the cutter is driven by the motor, if the speed of the cutter moving up and down is slow, the efficiency of cutting the excess rubber on the racket is low, and if the speed of the cutter moving up and down is fast, the rubber is easy to produce harmful gases due to frictional heat; because the cutter driven by the motor moves up and down to cut the rubber on the edge of the racket, that is, the sawing method is used to cut the rubber, it is difficult to ensure that the rubber edge is cut smoothly without a one-cut method, and a certain amount of dust will be generated, and the rubber edge of the racket will be further cut unevenly.

[0003] The Chinese invention patent with application number: 201711098450.9 discloses a table tennis racket rubber automatic laser cutting and pasting device, which includes a three-dimensional moving platform, a work station fixedly arranged on the three-dimensional moving platform, a racket bottom plate fixing device and a rubber fixing device arranged on the work station, the racket bottom plate fixing device and the rubber fixing device are rotatably connected, and the rubber fixing device can be flipped to overlap and cooperate with the racket bottom plate fixing device; a laser cutting device, a gluing device and a pressing device are correspondingly arranged above the work station. However, this table tennis racket rubber automatic laser cutting and pasting device processes the table tennis racket through a pressure plate and bolts, resulting in poor positioning stability of the table tennis racket. During the processing, the table tennis racket may be offset, which affects the cutting accuracy of the rubber and reduces the quality of the finished table tennis racket. Utility Model Content
