[0024] The inner pressure block 3 is located in the mixing outer cylinder 2 in a manner that it can move up and down in the mixing outer cylinder 2. A downward pressure generating device for pressing the inner pressure block 3 downward and limiting its upward movement is installed on the frame 1. Specifically, the inner pressure block 3 is a hollow cylindrical block with an open top. A central mounting column 31 extending upward from the inner pressure block 3 is erected on the inner bottom surface of the inner pressure block 3. A square base is located outside the disassembly cylinder 21 and is fixed with a mounting column. The mounting column is a mounting plate 5.

[0027] The utility model is an EVA rubber and plastic fast color mixing machine, embodiment 2, as shown in FIG. Figure 5 As shown, the difference between it and the first embodiment is that: the outer shell of the above-mentioned disassembly cylinder 21 is provided with a suspended water storage outer cylinder 7, and the water storage outer cylinder 7 is connected and matched with the disassembly cylinder 21, that is, the water storage outer cylinder 7 is a hollow cylindrical structure with an open top surface, and an embedding opening for the disassembly cylinder 21 to be embedded therein is provided on the inner bottom surface of the water storage outer cylinder 7, the inner side wall of the embedding opening is welded to the disassembly cylinder 21, and a water storage tank with an open top surface is formed between the outer side wall of the disassembly cylinder and the inner side wall of the water storage outer cylinder, the water storage outer cylinder 7 is below the handle 211 of the disassembly cylinder 21, and the top surface of the disassembly cylinder 21 is welded to the handle 211, and the installation vertical The column has a horizontal column 81 and a vertical column 82. The vertical column 82 is upright on the top surface of the frame and is outside the side of the disassembly cylinder 21. The horizontal column 81 is horizontally located above the vertical column 82 and is perpendicular to the vertical column 82. One end of the horizontal column 81 extends out of the vertical column 82. The part of the horizontal column 81 extending outside one end of the vertical column 82 is directly above the internal pressure block 3. The lower pressure generating device is installed on the horizontal column 81. The above-mentioned lower pressure generating device is a cylinder 9. The cylinder 9 is upright on the top surface of the horizontal column 81, and the output end of the cylinder 9 is directly above the internal pressure block 3 and is installed together with the upper end of the center mounting column 31.
[0028] The EVA rubber and plastic quick color-adjusting machine of this embodiment is different from the embodiment 1 in the control method of the inner pressure block 3 and the setting of the water storage outer cylinder 7 during use. When in use, water is filled in the water storage tank. The water in the water storage tank can effectively resist the problem of material temperature rise caused by friction, and can cool the material in the disassembly cylinder 21 without affecting the performance of the material due to temperature. At the same time, when it is necessary to move the inner pressure block 3 out of the disassembly cylinder 21, the output end of the cylinder 9 is driven to move upward, and the output end of the cylinder 7 drives the inner pressure block 3 to move out of the disassembly cylinder 21. If it is necessary to make the inner pressure block 3 enter the disassembly cylinder 21, the output end of the cylinder 9 is driven to move downward. , the internal pressure block 3 enters the disassembly cylinder 21, and generates downward pressure on the material in the mixing cylinder 21; the use of pneumatic pressurization can make the material quickly rub and heat up, and during the mixing process of the material, the material has a certain upward movement amplitude for the internal pressure block 3, and at the same time has the pressure of the internal pressure block pressing downward, so that the materials can be better fused together; moreover, the downward pressure can also be controlled by controlling the cylinder, so as to control the adjustment of different downward pressures for different materials; at the same time, the water storage outer cylinder 7 can increase the gravity of the disassembly cylinder 21, so that when the output end of the cylinder 4 moves upward, the disassembly cylinder 21 can also be relatively stable.
[0029] The product form of the present utility model is not limited to the illustrations and embodiments of this case. Any appropriate changes or modifications made by anyone with similar ideas should be deemed to be within the patent scope of the present utility model.
