[0024] Please refer to Figures 1-4 , the present utility model provides a technical solution: a rapid defoaming device for dipping plastic materials, including a stirring tank 1, and a rotating shaft 10 is rotatably installed on the inner bottom side of the stirring tank 1.

[0025] The lower end surface of the stirring tank 1 is fixedly installed with a motor 4; the output end of the motor 4 is fixedly connected to the bottom end of the rotating shaft 10.

[0026] A support frame 11 is slidably installed on the inner wall of the stirring tank 1.

[0027] A heating coil is fixedly installed inside the support frame 11.

[0028] On both sides of the outer wall of the rotating shaft 10, limiting grooves 14 are symmetrically opened; a fixing block 13 is rotatably installed on the inner side of the inner ring of the support frame 11; the fixing block 13 is slidably sleeved on the outside of the rotating shaft 10; limiting blocks 15 are fixedly connected to the positions of the fixing block 13 corresponding to the limiting grooves 14; the limiting blocks 15 are slidably installed inside the limiting grooves 14.

[0029] When the rotating shaft 10 rotates, the fixing block 13 is driven to rotate in the inner ring of the support frame 11 through the limiting block 15 and the limiting groove 14.

[0030] A plurality of stirring blades 12 are uniformly fixedly connected to the outer side of the bottom end of the fixing block 13. The top of the stirring tank 1 is snap-connected with a top cover 5. On the left and right sides of the upper end surface of the top cover 5, hydraulic cylinders 7 are fixedly installed, and the telescopic ends of the hydraulic cylinders 7 slide through to the inside of the stirring tank 1, and the telescopic ends of the hydraulic cylinders 7 are fixedly connected to the upper end surface of the support frame 11.

[0031] Further, a feed pipe 8 is fixedly connected to the upper end surface of the top cover 5, and a discharge pipe 3 is fixedly connected to the lower end surface of the stirring tank 1; a valve 2 is installed on the discharge pipe 3.

[0032] Further, a connecting pipe 6 is fixedly connected to the upper end surface of the top cover 5, and the connecting pipe 6 is communicated with the input end of an external vacuum pump.

[0033] Further, a display 9 is fixedly installed on the upper end surface of the top cover 5; a temperature sensor and a pressure sensor are fixedly installed on the inner wall of the stirring tank 1; both the temperature sensor and the pressure sensor are electrically connected to an external controller; the display 9 is also electrically connected to the external controller.

[0034] Working principle:

[0035] During use, add the rubber compound into the stirring tank 1 through the feed pipe 8. Start the motor 4, and the output shaft of the motor 4 rotates the rotating shaft 10. The rotation of the rotating shaft 10 drives the fixed block 13 to rotate within the inner ring of the support frame 11, and the rotation of the fixed block 13 drives the stirring blades 12 to stir the rubber compound, accelerating the discharge of gas in the rubber compound.

[0036] To improve the defoaming rate, energize the heating coil on the support frame 11, start the hydraulic cylinder 7, and the telescopic end of the hydraulic cylinder 7 extends to move the support frame 11 downward along the axis of the rotating shaft 10, so as to increase the contact area between the rubber compound and the heating layer and promote the discharge of gas in the rubber compound.

[0037] At the same time, the outer side of the support frame 11 can clean the inner wall of the stirring tank 1.

[0038] The downward movement of the support frame 11 drives the fixed block 13 to move downward, and then drives the stirring blades 12 to move downward to stir the rubber compound more evenly. The telescopic end of the hydraulic cylinder 7 reciprocates to drive the support frame 11 to move up and down reciprocally along the axis of the rotating shaft 10; thus enabling the heating coil to heat the rubber compound evenly.

[0039] To further improve the defoaming efficiency of the rubber compound, start the external vacuum pump. The vacuum pump extracts the air in the stirring tank 1 through the connecting pipe 6, thereby reducing the air pressure in the stirring tank 1 to accelerate the discharge of gas in the rubber compound and eliminate the bubbles in the rubber compound.

[0040] Through the temperature sensor and the pressure sensor, it is convenient to observe the temperature of the rubber compound and the pressure in the stirring tank 1, and transmit the temperature and pressure data to the external controller, which is then transmitted by the external controller to the display 9 and displayed through the display 9, facilitating the operator's observation and improving the safety of production.

However, the present invention is not limited to the above embodiments, and various changes can be made without departing from the gist of the present invention within the scope of knowledge possessed by those of ordinary skill in the art.
