In the production process of conveyor belts, since its raw material is rubber fiber and sometimes it needs to transport heavier objects during transportation, the material needs to be mixed during production to improve the toughness of the material. When rubber is mixed, it is generally necessary to use mixing equipment to mix the raw materials. The mixing equipment places the raw materials in a mixing chamber and mixes them under high temperature and high pressure. After the material is mixed, since the material has a certain viscosity, when the material is discharged from the mixing chamber, the material will stick to the rotor in the mixing chamber. Since the temperature is too high, manual cleaning will cause burns to the human body, which is not conducive to the use of the equipment.

[0032] The two first driving motors 5 rotate in opposite directions, and a sealing gasket is provided between the sealing plate 17 and the mixing chamber 4, so as to increase the sealing performance of the mixing chamber 4 and avoid leakage of the material during mixing.

[0033] Among them, the self-locking mechanism 7 includes a first fixed disk 8, a limiting column 9, a spring 10, a second fixed disk 11 and a limiting groove 12.

The limiting columns 9 are sleeved with springs 10. The second fixed disk 11 is installed on one of the support columns 2, and the second fixed disk 11 is provided with a limiting groove 12. The limiting column 9 is movably connected in the limiting groove 12; the mixing chamber 4 is effectively limited to avoid the mixing chamber 4 from rotating on its own, causing damage to the equipment, and further improving its stability.

[0034] Among them, one end of the spring 10 is fixedly connected to the limit column 9, and the other end is fixedly connected to the first fixed plate 8.

[0037] Among them, four bases 27 are installed on the bottom surface of the workbench 1, and the four bases 27 are located at the four corners of the bottom surface of the workbench 1, so as to further improve the stability of the equipment.

[0038] A mixing method for ultra-thin water cup stretching equipment, the specific steps of the mixing method are as follows:

[0039] Step 1: Place the raw materials to be mixed in the mixing chamber 4 in sequence, and control the hydraulic rod 15 to descend. At this time, the mixing chamber 4 gradually moves horizontally, and the sealing plate 17 approaches the mixing chamber 4 to seal it;

[0040] Step 2: Turn on the first driving motor 5 to make the two stirring rotors 6 rotate in different directions, so as to perform banburying and stirring on the materials;

[0041] Step 3: When the material is kneaded, the hydraulic rod 15 is shortened, and the kneading chamber 4 rotates in an inclined direction. As the hydraulic rod 15 shrinks, the cleaning mechanism 20 approaches the kneading chamber 4.

[0042] Step 4: When the mixing chamber 4 is tilted to a suitable position, the cleaning wheel 25 in the cleaning mechanism 20 is located inside the mixing chamber 4 , and the second driving motor 26 is controlled to control the cleaning wheel 25 to rotate to clean the mixing chamber 4 .

[0043] Working principle:

[0044] In the initial state of the equipment, the mixing chamber 4 is inclined at a certain angle, and the cleaning mechanism 20 is away from the mixing chamber 4. At this time, the raw materials are added into the mixing chamber 4 one by one. When the raw materials are placed, the hydraulic rod 15 is controlled to extend. When the hydraulic rod 15 is extended, the hydraulic rod 15 drives the sealing plate 17 to descend. When the sealing plate 17 descends, the hydraulic rod 15 drives the gear 13 to rotate through the rack 16. With the rotation of the gear 13, the first rotating column 3 and the second rotating column 18 rotate at the same time. At this time, the mixing chamber 4 gradually rotates in a horizontal direction. When the mixing chamber 4 rotates to a suitable position, the sealing plate 17 on the hydraulic rod 15 is gradually sealed on the mixing chamber 4. With the rotation of the first rotation, the first fixed disk 8 rotates at this time, and the limiting column 9 slidably connected on the first fixed disk 8 rotates in the limiting groove 12. When the limiting column 9 rotates in the limiting groove 12, the spring 10 is in a compressed state. When the limiting column 9 rotates to the groove in the limiting groove 12, the spring 10 is reset at this time. The limiting column 9 is limited in the limiting groove 12. At this time, the first fixed plate 8 and the second fixed plate 11 are in a fixed state. At this time, the mixing chamber 4 is fixed, and then the first drive motor 5 is controlled to work. When the first drive motor 5 is working, the first drive motor 5 drives the stirring rotor to rotate to stir and mix the raw materials. When the materials are mixed, the hydraulic rod 15 can be retracted. At this time, the mixing chamber 4 rotates under the drive of the gear 13, and the pulley 19 drives the cleaning mechanism 20 to gradually approach the mixing chamber 4. The pulley 19 drives the worm 21 to rotate, and the worm 21 drives the threaded rod 22 to rotate through the worm gear 23. With the continuous rotation of the hydraulic rod 15, when the cleaning shaft in the cleaning mechanism 20 moves to the inside of the mixing chamber 4, the hydraulic rod 15 stops working. At this time, the second drive motor 26 is controlled to drive the cleaning shaft to clean the mixing chamber 4. When the mixing chamber 4 is discharged and cleaned, the above work is repeated, and the equipment can work repeatedly.

[0045] The mixing chamber 4 in the equipment is tilted in the initial state, which makes it more convenient for people to add materials. When the mixing chamber 4 cooperates with the hydraulic rod 15 and the sealing plate 17, the angle of the mixing chamber 4 can be effectively changed, making it more convenient for people to add materials and discharge materials. When the mixing chamber 4 is discharging materials, the cleaning mechanism 20 can simultaneously clean the mixing chamber 4, thereby ensuring the cleanliness of the discharging of the mixing chamber 4 and avoiding the material in the mixing chamber 4 from sticking to the inner wall of the mixing chamber 4. The various parts in the equipment cooperate with each other, making the equipment more automated when in use, avoiding manual cleaning and manual scalding. The various parts in the equipment cooperate with each other, making the equipment avoid using more power components when in use, thereby further saving energy and avoiding energy waste. The synchronous cooperation between the mixing chamber 4 and the cleaning mechanism 20 allows the cleaning mechanism 20 to quickly and precisely clean it, further improving the automation of the equipment and accelerating the work efficiency of the equipment.
