[0032] When the rubber needs to be mixed, the workers first place various mixing required ingredients in the inside of the hopper 22, and then control the operation of the discharging motor 24 and the grinding motor 8 through the motor controller. The operation of the discharging motor 24 drives the rotation of the discharging plate 23, which further makes the material fall between the two sets of grinding rollers 3 through the quantitative bin 21 and the discharge port 20. The operation of the grinding motor 8 drives the rotation of the grinding rollers 3, and the relative rotation of the two sets of grinding rollers 3 grinds the raw materials. When mixing, the workers need to adjust the spacing between the two sets of grinding rollers 3. At this time, the workers control the two sets of adjusting motors 7 to operate simultaneously through the motor control. The operation of the adjusting motor 7 drives the rotation of the bidirectional screw rod 6, which further drives the relative displacement of the two sets of adjusting plates 5 along the first moving groove 4 through the rotation of the bidirectional screw rod 6.

[0035] When the rubber needs to be mixed, the staff first places various mixing required ingredients in the hopper 22, and then controls the operation of the discharging motor 24 and the grinding motor 8 through the motor controller. The operation of the discharging motor 24 drives the discharging plate 23 to rotate, and further makes the material fall between the two sets of grinding rollers 3 through the quantitative bin 21 and the discharge port 20. When the material needs to be added, the staff stops the discharging motor 24, and at this time the material will be stacked above the discharging plate 23, and the discharging is stopped.
[0036] The rotation of the discharging plate 23 driven by the operation of the discharging motor 24 will batch the material in the hopper 22 into the two sets of grinding rollers 3 through the discharge port 20. Compared with the traditional device, the device can automatically add the additives required for rubber mixing, reducing the work burden, ensuring the uniformity and completeness of rubber mixing through batch quantitative addition, and improving the product quality.

[0051] Working principle and use process of the utility model:
[0052] When the rubber needs to be mixed, the staff first places the mixing agents needed in the hopper 22, and then controls the discharging motor 24 and the grinding motor 8 to operate by the motor controller. The operation of the discharging motor 24 drives the discharging plate 23 to rotate, and further makes the material fall between the two groups of grinding rollers 3 through the quantitative bin 21 and the discharging port 20. The operation of the grinding motor 8 drives the grinding rollers 3 to rotate, and the two groups of grinding rollers 3 rotate relative to each other to grind the raw materials. When the rubber is mixed, the staff needs to adjust the interval between the two groups of grinding rollers 3. At this time, the staff controls the two groups of adjusting motors 7 to operate simultaneously by the motor controller. The operation of the adjusting motor 7 drives the bidirectional lead screw 6 to rotate, and further drives the two groups of adjusting plates 5 to relatively displace along the first moving groove 4. At this time, the interval between the two groups of grinding rollers 3 is adjusted, and when the grinding rollers 3 are adjusted, the adjusting plate 5 drives the extension plate 9 to displace along the guide column 13, and the displacement of the extension plate 9 drives the moving plate 15 to displace. At this time, the moving plate 15 and the grinding rollers 3 displace synchronously. When the scraper 17 needs to be used, the staff starts the hydraulic telescopic rod 12, and the hydraulic telescopic rod 12 drives the top plate 11 to move downward until the scraper 17 is located on the outer surface of the grinding roller 3. The staff can start the double-shaft motor 19 by the motor controller. The operation of the double-shaft motor 19 drives the two groups of lead screws 18 to rotate, and further drives the two groups of scrapers 17 to displace along the limiting groove 16 to scrape the rubber adhered to the outer wall of the grinding roller 3, and completes the mixing operation.
