[0002] Dipping is a plastic coating process, also known as plastic coating, hot dipping or hot-compression coating. This process heats the metal or other substrate and immerses it in plastic powder or liquid, causing the plastic powder or liquid to melt at high temperature and evenly adhere to the surface of the substrate to form a layer of plastic coating. Bubbles in the plastic dipped rubber are one of the main factors affecting product quality, so degassing is required. The principle of degassing is to reduce the pressure in the degassing barrel to make the water vapor in the viscose boil and evaporate, thereby taking away air, carbon disulfide (CS2), hydrogen sulfide (H2S) and other gases.

[0021] The utility model provides Figures 1 to 3 The material guiding device for degassing plastic dipped rubber material shown in the figure comprises a stirring barrel 1. The bottom of the stirring barrel 1 is welded with fixed support legs for overall support.

[0024] The motor 4 is fixed by bolts on the upper cover 3, and the output shaft of the motor 4 vertically penetrates into the mixing barrel 1 downward and is rotatably connected with the upper cover 3. A connecting sleeve 18 is vertically placed in the mixing barrel 1, and the top of the connecting sleeve 18 is coaxially fixedly connected with the output shaft of the motor 4. The internal cavity of the connecting sleeve 18 is a polygonal cavity, and the polygonal cavity of the connecting sleeve 18 is limited and slidably matched with a matching stirring shaft, and the stirring shaft vertically extends downward out of the polygonal cavity of the connecting sleeve 18.

[0025] The driving member is assembled in the multi-deformable cavity of the connecting sleeve 18, and the driving member is connected to the stirring shaft by transmission. The driving member includes an electric push rod 19, and the electric push rod 19 is fixedly connected to the connecting sleeve 18. The output shaft of the electric push rod 19 is vertically downward and fixedly connected to the stirring shaft, and is used to push the stirring shaft to slide up and down.

[0026] A plurality of first stirring rods 14 are welded and fixed on the stirring shaft along the radial direction of the output shaft of the motor 4, and are used for stirring and mixing the raw materials for manufacturing the plastic dipping compound.

[0027] A support rod 15 is horizontally placed in the mixing barrel 1, and the support rod 15 is fixedly connected to the mixing barrel 1. A vertical rotating shaft is mounted on the support rod 15, and the rotating shaft is rotatably connected to the support rod 15. The rotating shaft is coaxial with the output shaft of the motor 4. A transmission member is mounted between the mixing shaft and the rotating shaft, and the mixing shaft cooperates with the rotating shaft through the transmission member to drive the rotating shaft to rotate.

[0028] The transmission member includes a spline and a keyway 16 matched with the spline. The spline is welded and fixed to the bottom of the stirring shaft and is coaxial with the output shaft of the motor 4. The keyway 16 is chiseled out on the top of the rotating shaft, and the keyway 16 is aligned with the spline. When the spline is inserted into the keyway 16, a snap-on transmission fit is formed to drive the rotating shaft to rotate.

[0029] A connecting rod is welded and fixed on the rotating shaft, and the end of the connecting rod away from the rotating shaft is fixedly connected to the second stirring rod 17, and the second stirring rod 17 is in sliding contact with the inner wall of the bottom of the stirring barrel 1, so as to scrape up the raw materials that have settled on the bottom.

[0030] A vacuum pump 7 is bolted to the upper cover 3, and the air suction port of the vacuum pump 7 is fixedly connected to an air suction pipe 8, and the air suction pipe 8 is fixedly connected to the mixing barrel 1. The air outlet of the vacuum pump 7 is fixedly connected to an exhaust pipe 9, which is used to extract the air in the mixing barrel 1 and form a negative pressure in the mixing barrel 1.

[0031] A heating cavity 13 is bored in the barrel body of the mixing barrel 1 , a heating plate 12 is installed in the heating cavity 13 , and the heating plate 12 is fixedly connected to the mixing barrel 1 , so as to heat the raw materials in the mixing barrel 1 .

[0032] The mixing barrel 1 is fixedly connected to a vent pipe, in which a one-way valve 2 is installed. The one-way valve 2 is fixedly connected to the vent pipe. The function of the one-way valve 2 is to control the gas inside the mixing barrel 1 to flow out of the vent pipe and prevent the gas outside the mixing barrel 1 from flowing into the mixing barrel 1 through the vent pipe.

[0033] Working principle: When in use, the first solenoid valve 6 is controlled to open the material guide pipe 5, and the raw materials for making the plastic dipping rubber material are injected into the mixing barrel 1 through the material guide pipe 5. After the filling is completed, the first solenoid valve 6 is controlled to close the material guide pipe 5.

[0034] Then start the motor 4 and the vacuum pump 7 at the same time. The output shaft of the motor 4 drives the connecting sleeve 18 to rotate, the connecting sleeve 18 drives the stirring shaft to rotate, and the stirring shaft drives the first stirring rod 14 to stir and mix the raw materials, and during the stirring process, the first stirring rod 14 breaks the bubbles in the rubber.

[0035] At the same time, the heating plate 12 heats the rubber in the mixing barrel 1, causing the gas in the bubbles to expand and thus accelerate the bursting of the bubbles. If the air pressure inside the mixing barrel 1 increases sharply during the heating process, the high-pressure gas can flow out of the mixing barrel 1 through the one-way valve 2 through the vent pipe.

[0036] During this process, the vacuum pump 7 extracts the heated gas in the mixing barrel 1 through the exhaust pipe 8, and negative pressure is formed in the mixing barrel 1. Under the action of the negative pressure, the rupture of bubbles in the rubber material is intensified, thereby improving the degassing efficiency.

[0037] After a long period of stirring, a portion of the heavier raw materials will settle on the inner wall of the bottom of the mixing barrel 1 under the action of centripetal force and gravity. At this time, the electric push rod 19 is started, and the output shaft of the electric push rod 19 extends and drives the stirring shaft to move closer to the rotating shaft. When the spline on the stirring shaft is inserted into the keyway 16 on the rotating shaft, the spline and the keyway 16 form a snap connection, and then the stirring shaft drives the rotating shaft to rotate through the spline and the keyway 16. The rotating shaft drives the second stirring rod 17 through the connecting rod to scrape the raw materials settled on the inner wall of the bottom of the mixing barrel 1.

[0038] At the same time, the output shaft of the electric push rod 19 reciprocates and retracts, and the stirring shaft drives the spline to slide up and down in the keyway 16. In this process, the spline is always engaged with the keyway 16, and the top of the stirring shaft is always located in the polygonal cavity of the connecting sleeve 18.

[0039] Afterwards, the second stirring rod 17 scrapes up the raw materials deposited on the inner wall of the bottom of the stirring barrel 1, and cooperates with the stirring shaft to drive the first stirring rod 14 to move up and down during the stirring process, so that the raw materials are stirred and mixed more fully, the mixing efficiency is higher, the degassing is more thorough, and the quality of the rubber is more uniform.

[0040] After the stirring and mixing is completed, the second solenoid valve 10 is controlled to open the discharge pipe 11 to allow the degassed adhesive to flow out.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
