Description

Technical Field

[0001] The utility model relates to the technical field of table tennis racket film production, in particular to a vulcanization device for table tennis racket film production. Background Technique

[0002] A table tennis racket is a racket used by table tennis players during the game. It is usually composed of a bottom plate and a surface covering (also known as a "film"). The film is a general term for vulcanized rubber. The table tennis racket film is an important part of the racket and is in direct contact with the ball. Therefore, it plays a crucial role during the game. First, the weight of the film can increase the weight of the racket, thus becoming an important part of the racket to generate momentum. Second, the film can directly contact the ball and affect the trajectory and performance of the ball by creating or changing the rotation, speed, running direction, arc, and landing point of the ball. In addition, the film can transmit the impact force of the ball to the sponge and the bottom plate during the game, causing them to generate elastic force, thereby affecting the rebound effect of the ball. Finally, the film will deform during the interaction with the ball, and this deformation further affects the performance of the ball and the player's ball control ability.

[0003] During the production process of table tennis racket film, vulcanization is a key step. It involves using a vulcanizer to heat and press the film to connect the rubber molecules with each other, thereby enhancing the elasticity and durability of the film. When the film is vulcanized, the temperature of the film is relatively high after vulcanization and molding, and it is not convenient to cool it immediately. The film is easy to stick to the mold, resulting in smooth demoulding problems. Directly removing it easily causes damage, affecting the yield rate. Therefore, it is urgently needed to be improved. Content of the Utility Model

[0004] The purpose of the utility model is to provide a vulcanization device for table tennis racket film production to solve the problems raised in the above background technique.

The vulcanization table is arranged at the top of the device body, and a first rotation driving member is installed inside the vulcanization table. The output end of the first rotation driving member extends to the top of the vulcanization table and is equipped with a turntable. The lower mold is arranged at the top of the turntable. A device frame is fixed above the device body, and a vulcanization machine head is arranged below the device frame. An upper mold is installed inside the vulcanization machine head, and the upper mold cooperates with the lower mold. A telescopic driving member is installed at the top of the device frame, and the output end of the telescopic driving member is fixedly connected to the vulcanization machine head. A lead screw is installed at the top of the device body, and a second rotation driving member is installed on the outer wall of the device body at the position of the lead screw. The output end of the second rotation driving member is fixedly connected to the lead screw. Cooling tables are fixed at the top of the device body on both sides of the lead screw. The air nozzle is installed at the top of the cooling table, a cross arm is installed at the top of the cooling table above the air nozzle, the blow pipe is installed at the bottom of the cross arm, and air delivery pumps are installed on both sides inside the device body.

[0006] Preferably, a treatment box is installed on one side of the top of the device frame, and an activated carbon block is arranged on one side inside the treatment box.

[0007] Preferably, an air extraction pump is installed inside the treatment box on one side of the activated carbon block. When the air extraction pump operates, the telescopic hose sucks the vulcanization waste gas in the vulcanization machine head into the treatment box, and the activated carbon block adsorbs and treats the waste gas, which is convenient for treating the waste gas generated during vulcanization and reduces pollution.

[0008] Preferably, a telescopic hose is installed on one side of the bottom of the treatment box, and the bottom end of the telescopic hose is communicated with the vulcanization machine head.

[0009] Preferably, a top cover is installed at the top of the treatment box at the position of the activated carbon block, and the top cover can be removed to facilitate the regular replacement of the activated carbon block.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] The second rotation driving member drives the lead screw to rotate, so that the vulcanization table drives the lower mold to move away from below the device frame. When the lower mold passes through the cooling table, the air delivery pump extracts external cooling gas through a pipeline and transports it to the air nozzles and air blowing pipes through an air delivery pipeline. The air nozzles eject the cooling gas to blow air at the two edges of the film, and the air blowing pipes blow air on the surface of the film. Immediately afterwards, the first rotation driving member drives the turntable to rotate, so that the lower mold rotates by ninety degrees. The lead screw drives the lower mold to pass between the cooling tables again, so that the air nozzles blow air at the other two edges of the film, causing all four sides of the film to separate from the lower mold. The air blowing pipes blow air on the surface of the film to cool down the film. By blowing air and cooling the film, it is convenient for the film to be quickly demolded, not easy to stick, the demolding is smoother, and it is not easy to break.

[0026] Specifically, the telescopic driving member 7 drives the vulcanizing head 5 to move upward, separating the upper mold 6 from the lower mold 3. The second rotary driving member 20 drives the lead screw 19 to rotate in the reverse direction, causing the vulcanizing table 2 to drive the lower mold 3 to move away from below the device frame 4. When the lower mold 3 passes by the cooling table 12, the air delivery pump 13 extracts external cooling gas through the pipeline and conveys it to the air nozzles 16 and the air blowing pipes 18 through the air delivery pipeline 1301. The cooling gas can be nitrogen. At this time, the air nozzles 16 eject the cooling gas to blow air at the two edges of the film, and the air blowing pipes 18 blow air on the surface of the film. Immediately afterwards, the first rotary driving member 14 drives the turntable 15 to rotate, causing the lower mold 3 to rotate by ninety degrees. The lead screw 19 drives the lower mold 3 to pass between the cooling tables 12 again, enabling the air nozzles 16 to blow air at the other two edges of the film, separating all four sides of the film from the lower mold 3, and the air blowing pipes 18 blow air on the surface of the film to cool down the film. By blowing air and cooling the film, it is convenient for the film to be quickly demolded, not easily sticky, and the demolding is smoother and not easily damaged;

The top cover 801 can be removed so that the activated carbon block 9 can be replaced regularly, and then, the telescopic drive member 7 drives the vulcanizing machine head 5 to move upward, so that the upper mold 6 and the lower mold 3 are separated, and the second rotating drive member 20 drives the screw 19 to move upward. The first rotating drive member 14 drives the turntable 15 to rotate, so that the vulcanizing table 2 drives the lower mold 3 to move away from the bottom of the device frame 4. When the lower mold 3 passes through the cooling table 12, the air pump 13 extracts the external cooling gas through the pipeline and transmits it to the air nozzle 16 and the blowing pipe 18 through the air pipeline 1301.
