Description

Technical Field

[0001] The utility model relates to the technical field of rubber mixing devices, and particularly relates to a rubber mixing device for the production of table tennis racket rubbers. Background Technique

[0002] Table tennis racket rubbers are an important part of table tennis sports. They directly affect the performance of the racket and the technical level of the user. When producing table tennis racket rubbers, a rubber mixing device is required. The rubber mixing device is mainly used for the mixing and processing of rubber raw materials, so as to subsequently make the rubbers required for table tennis rackets.

[0003] When producing table tennis racket rubbers, the mixed rubber raw materials need to be put into the rubber mixing device for mixing. Through the extrusion and friction of the rollers, the raw materials are evenly mixed and reach a certain plasticity and elasticity. Since the technical levels and personal preferences of table tennis players are different, there are also different requirements for the thickness of the rubbers. This requires controlling the distance between the rollers during rubber production. Generally, the general rubber mixing device needs manual operation to adjust the rollers, which is time-consuming and laborious. Content of the Utility Model

[0004] The purpose of the utility model is to provide a rubber mixing device for the production of table tennis racket rubbers, so as to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A rubber mixing device for the production of table tennis racket rubbers, including a rubber mixing device main body, a bracket, a movable roller and a fixed roller. A fixed roller is arranged on one side inside the rubber mixing device main body, and a second rotation driving mechanism is fixed on the rubber mixing device main body on one side of the fixed roller. The output end of the second rotation driving mechanism is connected to the fixed roller. And a bracket is arranged on the other side inside the rubber mixing device main body. A movable roller is arranged inside the bracket, and a first rotation driving mechanism is fixed at one end on one side of the bracket.

[0007] Preferably, an exhaust gas treatment chamber is arranged on the top of the rubber mixing device main body through a frame body, and an air inlet hood is arranged at the bottom of the exhaust gas treatment chamber.

[0008] Preferably, an air extraction fan is provided at the top inside the exhaust gas treatment chamber, and first fan blades are evenly distributed outside the air extraction fan.

[0009] Preferably, filter nets are evenly arranged inside the exhaust gas treatment chamber, and the filter nets are all made of activated carbon material.

Then, the first rotation driving mechanism 12 and the second rotation driving mechanism 8 drive the movable roller 4 and the fixed roller 7 to rotate relatively respectively, generating extrusion and friction forces on the raw materials, so that the raw materials are evenly mixed and reach a certain plasticity and elasticity to form rubber sheets;

[0025] A lead screw 9 is arranged on one side inside the main body 1 of the rubber mixing device, and a driving block 3 is sleeved on the lead screw 9.

A third rotation driving mechanism 11 is fixed at one end on one side of the main body 1 of the rubber mixing device, and the output end of the third rotation driving mechanism 11 is connected to the lead screw 9;

[0026] The third rotation drive mechanism 11 can drive the screw rod 9 to rotate, causing the drive block 3 to move along the screw rod 9, thereby driving the bracket 2 and the movable roller 4 to move, automatically adjusting the distance between the movable roller 4 and the fixed roller 7, and further adjusting the thickness of the rubber sheet produced to meet the production requirements of table tennis racket rubber sheets of different specifications;

[0027] On one side of the rubber mixing device main body 1 away from the screw rod 9, a guide rod 13 is provided. A guide sleeve 14 is sleeved on the guide rod 13, and one end of the guide sleeve 14 is connected to the bracket 2 to guide and limit the bracket 2;

[0028] At the top of the rubber mixing device main body 1, an exhaust gas treatment chamber 6 is provided through a frame body 5, and an air inlet hood 15 is provided at the bottom of the exhaust gas treatment chamber 6. The air inlet hood 15 has a trapezoidal structure, and air inlets 18 are evenly distributed at the bottom of the air inlet hood 15;

[0029] At the top end inside the exhaust gas treatment chamber 6, an exhaust fan 16 is provided, and first fan blades 19 are evenly distributed on the outside of the exhaust fan 16;

[0030] During the rubber mixing process, the operation of the exhaust fan 16 drives the first fan blades 19 to rotate, generating suction above the top fixed roller 7 and the movable roller 4, and the exhaust gas enters the exhaust gas treatment chamber 6 through the air inlets 18 at the bottom of the air inlet hood 15;

[0031] Filter nets 17 are evenly arranged inside the exhaust gas treatment chamber 6, and the filter nets 17 are all made of activated carbon material. After the exhaust gas enters the exhaust gas treatment chamber 6 and is filtered and purified by the filter nets 17, it is discharged and is not likely to harm the working environment and workers;

[0032] Sliding rails 10 are provided on both sides of the filter net 17, and sliding grooves matching the sliding rails 10 are opened on both sides inside the exhaust gas treatment chamber 6, which is conducive to the removal and replacement of the filter net 17;

[0033] Second fan blades 20 are evenly distributed at the central position at the bottom of the exhaust fan 16, and the rotation direction of the second fan blades 20 is the same as that of the first fan blades 19;

[0034] The air flow generated by the second fan blades 20 flows towards the first fan blades 19 and flows upward together with the air flow generated by the first fan blades 19, increasing the wind force and thus improving the exhaust efficiency of the exhaust gas;

[0035] The specific model specifications of the first rotation drive mechanism 12, the second rotation drive mechanism 8, and the third rotation drive mechanism 11 need to be determined by selection calculation according to the specification parameters of the device. The selection calculation method is prior art and will not be elaborated in detail here.

[0036] Working principle: When the embodiment of the present application is in use, the raw materials for producing the table tennis racket rubber sheet are placed in the gap between the fixed roller 7 and the movable roller 4. Then, the first rotation drive mechanism 12 and the second rotation drive mechanism 8 drive the movable roller 4 and the fixed roller 7 to rotate relatively respectively, generating extrusion and frictional forces on the raw materials, so that the raw materials are evenly mixed and reach a certain plasticity and elasticity to form the rubber sheet. During the rubber mixing process, the exhaust fan 16 operates to drive the first fan blade 19 to rotate, generating a suction force above the top fixed roller 7 and movable roller 4. The waste gas enters the waste gas treatment chamber 6 through the air inlet 18 at the bottom of the air inlet hood 15, and is discharged after being filtered and purified by the filter screen 17. The second fan blades 20 are evenly distributed at the bottom of the exhaust fan 16. The rotation direction of the second fan blades 20 is the same as that of the first fan blade 19. The airflow generated by the second fan blades 20 flows towards the first fan blade 19 and flows upward together with the airflow generated by the first fan blade 19, increasing the wind force and thus improving the efficiency of waste gas discharge. In addition, the third rotation drive mechanism 11 can drive the lead screw 9 to rotate, so that the drive block 3 moves along the lead screw 9, thereby driving the bracket 2 and the movable roller 4 to move, automatically adjusting the distance between the movable roller 4 and the fixed roller 7, and further adjusting the thickness of the produced rubber sheet to meet the production requirements of table tennis racket rubber sheets of different specifications.
