The end of the flexible hose 57 away from the second material extractor 56 is connected to the bottom inner wall of the raw material box 31. The baffle 510 is slidably connected to the left inner wall of the bracket 2. The mounting base 51 is connected to the bottom inner wall of the bracket 2. The stirring rod 513 is slidably connected to... On the bottom inner wall of the bracket 2, there are several control lines 514. These control lines 514 are fixedly connected to the outer side walls of the control panel 58, button 511, second feeder 56, and first feeder 53, respectively.

[0026] Reference Figures 3-4The auxiliary mechanism 6 includes a docking groove 61, which is formed on the top inner wall of the mounting base 51. A lever 62 is slidably connected to the top inner wall of the bracket 2. A limit plate 63 is fixedly connected to the right outer wall of the lever 62. The first mixing cylinder 52 and the second mixing cylinder 55 are locked and limited by the limit plate 63 and the adjusting plate 65. An adjusting plate 65 is slidably connected to the top inner wall of the bracket 2. An insert plate 66 is fixedly connected to the left outer wall of the adjusting plate 65.

[0027] Working principle: By activating the first material extractor 53 and the second material extractor 56, the various processed materials inside the raw material box 31 and the batching box 4 are drawn into the first mixing cylinder 52 and the second mixing cylinder 55 for pre-precise mixing of corresponding amounts. Then, the telescopic hydraulic cylinder 59 is activated to move the baffle 510. The movement of the baffle 510 causes the processed materials inside the first mixing cylinder 52 and the second mixing cylinder 55 to fall into the bottom of the support 2. At the same time, the movement of the baffle 510 separates from the pressing of the button 511, allowing the signal to be transmitted to the control panel 58 to start the motor oscillator 512. The motor oscillator 512 drives the stirring rod 513 to swing back and forth inside the support 2, making the stirring rod 513 mix the processed materials evenly and making the mixed material ratio more uniform. Then, the material is discharged through the discharge valve 32. The material is discharged to the next sheet extrusion process. At the same time, after the material is discharged, the telescopic hydraulic cylinder 59 retracts, causing the baffle 510 to move. The baffle 510 moves and fits against the inner wall of the bracket 2. Simultaneously, the baffle 510 moves and presses the button 511, transmitting a signal to the control panel 58. Then, the control panel 58 restarts the second material extractor 56 and the first material extractor 53 through the control line 514 to perform proportioning and extraction, and repeats the proportioning operation. At the same time, under long-term use, the mixing cylinder is prone to the adhesion of processed material. By pulling the lever 62 and the adjusting plate 65 to move closer together, the limit plate 63 and the insert plate 66 are separated from the second mixing cylinder 55 and the first mixing cylinder 52. Then, the second mixing cylinder 55 and the first mixing cylinder 52 are separated from the mounting base 51, making it convenient for personnel to maintain, replace and clean the inside.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
