Description

Technical Field

[0001] This utility model relates to the technical field of raw material mixing devices, specifically a raw material mixing device for the production of softened skin for automotive dashboards. Background Technology

[0002] The production of softened dashboard skins for automobiles involves the precise mixing of various materials to ensure the quality and performance of the final product. The raw material mixing unit plays a crucial role in this process, ensuring that the various raw materials are mixed evenly in the correct proportions.

[0003] Common raw material mixing devices typically put raw materials directly into the mixing chamber for mixing. However, due to the differences in particle size between raw materials, if raw materials of different specifications cannot be crushed to the same particle size, raw materials of different particle sizes may stratify during the mixing process. Larger particles may sink to the bottom due to gravity, while smaller particles may remain on the top layer, resulting in uneven distribution of the final mixture. Utility Model Content

[0029] The position of the U-shaped plate 8 can be precisely controlled by the rotation of the threaded rod 13 driven by the third motor 15, thereby changing the gap between the first crushing roller 6 and the second crushing roller 10. This function is crucial for adapting to raw materials with different particle sizes, hardness, or viscosity, ensuring the consistency of crushing effect. The guide rod 16 guides the U-shaped plate 8 to move smoothly back and forth, preventing the offset or shaking caused by the threaded transmission from affecting the crushing accuracy. The third motor 15 is used to drive the threaded rod 13 to realize the automatic adjustment of the crushing roller gap, improving the intelligence level of the equipment.

[0030] Furthermore, a filter plate 18 with a left-high and right-low tilt is rotatably connected to the lower part of the mixing box 1. The left side of the filter plate 18 is rotatably connected to the left side of the inner wall of the mixing box 1. A discharge port 101 is opened at the bottom right side of the mixing box 1. The right side of the filter plate 18 extends to the right side of the outside of the mixing box 1 and is slidably connected to the inner wall of the discharge port 101.

[0031] The hopper 17 is fixedly connected to the center of the inner wall of the mixing box 1, located below the first crushing roller 6 and the second crushing roller 10. It is used to receive the raw material particles after being crushed by the double rollers and plays a transition role.

The left side of the filter plate 18 is rotatably connected to the inner wall of the mixing box 1, and the right side extends to the discharge port 101 and slides with it to realize the particle size screening function of the crushed raw material. Larger particles are intercepted above the filter plate 18, while qualified particles enter the lower part or are discharged through the filter holes. The inclined angle helps the material flow smoothly and prevents blockage.

[0032] Furthermore, a discharge pipe 19 with a left-high and right-low tilt is fixedly connected to the lower right side of the outer wall of the mixing box 1. The discharge pipe 19 is parallel to the filter plate 18. A high-frequency vibrator 20 is fixedly connected to the bottom right side of the filter plate 18 inside the mixing box 1. A transparent observation window 21 is embedded on the front surface of the mixing box 1. A controller 22 is fixedly connected to the lower left side of the outer wall of the mixing box 1.

[0033] The discharge port 101 is located at the bottom right side of the mixing chamber 1. The discharge pipe 19 is fixed to the lower right side of the outer wall of the mixing chamber 1, with the inclination direction consistent with that of the filter plate 18. The high-frequency vibrator 20 is fixed to the bottom right side of the filter plate 18, providing high-frequency vibration power to enhance the screening efficiency of the filter plate 18 and prevent fine powder from agglomerating or clogging the filter holes.

[0034] Raw materials enter the upper area of ​​the mixing chamber 1 through the feed hopper 3. The raw materials fall naturally between the first crushing roller 6 and the second crushing roller 10 for preliminary crushing. The first motor 7 drives the first rotating rod 5 to rotate, which in turn drives the first crushing roller 6 to rotate. The second motor 11 drives the second rotating rod 9 to rotate, which in turn drives the second crushing roller 10 to rotate synchronously in the opposite direction. The first crushing roller 6 and the second crushing roller 10 mesh with each other, forming a shearing force to efficiently crush the raw materials. The crushed raw materials fall into the feed hopper 17 below and are guided to the middle area of ​​the mixing chamber 1. The third motor 15 is started to drive the threaded rod 13 to rotate. The threaded rod 13 drives the threaded sleeve 12 to move back and forth, thereby pushing the U-shaped plate 8 and the second crushing roller 10 on it to adjust back and forth, realizing the automatic adjustment function of the crushing gap to adapt to different raw material requirements. The guide rod 16 ensures that the U-shaped plate 8 moves smoothly and avoids deviation or jamming.

[0035] The crushed raw materials continue to flow downwards into the lower area of ​​the mixing chamber 1, where they are screened by an inclined filter plate 18. A high-frequency vibrator 20 is installed at the bottom right side of the filter plate 18 to provide high-frequency vibration power and improve screening efficiency. A transparent observation window 21 is embedded in the front surface of the mixing chamber 1 to observe the crushing, screening and mixing process in real time.
