[0032] Working principle: When in use, first place the device body 1 at the designated position, and the user introduces the TPU elastomer material into the inside of the guide box 102 through the feed frame 103. Then, the user operates the control button 101, so that the control button 101 controls the motor body 304 on the surface of the box body 301 to work, and the motor body 304 drives the rotating rod 303 to rotate.

The user then operates the control button 101, so that the control button 101 controls the drive motor 402 to work, and the drive motor 402 drives the adjusting screw 401 to rotate inside the fixed box 113, and the adjusting screw barrel 4034 drives the adjusting screw barrel 4034 to move inside the fixed box 113 under the thread cooperation of the adjusting screw 401 and the adjusting screw barrel 4034. At this time, the adjusting screw barrel 4034 slides inside the guide groove 4033, and the adjusting screw barrel 4034 is guided under the action of the guide groove 4033. When the adjusting screw barrel 4034 moves, the adjusting screw barrel 4034 drives the second electric push rod 4031 and the baffle plate 4032 to move to the desired position, and the user The control button 101 is then operated to control the second electric push rod 4031 to work. The second electric push rod 4031 drives the baffle plate 4032 to move, so that the baffle plate 4032 moves to contact the surface of the discharge barrel 112. The surface of the discharge barrel 112 is blocked by the baffle plate 4032. The user adjusts the position of the baffle plate 4032 so that the TPU elastomer material can be discharged through the gap between the discharge barrel 112 and the baffle plate 4032, and the discharge amount of the discharge barrel 112 is adjusted to realize the function of the pre-mixing device to adjust the discharge amount, so that the pre-mixing device can adjust the discharge amount of the material inside the device body 1 according to the discharge needs when in use, so that the pre-mixing device can better meet the user's usage needs when in use, and finally complete the use of the pre-mixing device.
