The discharge diameter of the hopper 4 can be adjusted by the setting of the sealing disc 53. A locking hole is opened on the surface of the left fixed plate 51. 54. Multiple locking holes 54 are provided, arranged in a ring array on the left fixed plate 51. The locking holes 54 facilitate the use of locking balls 56 for locking. An elastic block 55 is bonded to the inner wall of the driven plate at the left end of the rotating rod 52, and a locking ball 56 is bonded to the right end of the elastic block 55. The locking ball 56 is slidably connected to the locking holes 54. Through the setting of the rotating rod 52 and the sealing plate 53, the discharge diameter of the hopper 4 can be adjusted, and the sealing plate 53 can be rotated and positioned under the action of the locking holes 54 and the locking balls 56.

[0025] Please see Figure 1 , Figure 2 , Figure 3 , Figure 5 The support frame 2 is equipped with a lifting mechanism 8, which includes a slide groove 81. The vertical part of the support frame 2 has a slide groove 81, and the horizontal part of the support frame 2 is fixedly mounted with a servo motor 82. The output shaft of the servo motor 82 is rotatably connected to the horizontal part of the support frame 2. The output shaft of the servo motor 82 is fixedly connected with a screw 83. The outer side of the screw 83 is threadedly connected with a movable piece 84. The movable piece 84 is slidably connected to the slide groove 81. The lower end of the movable piece 84 is fixedly connected with a mounting piece 85, and the end face of the movable piece 84 is fixedly connected with a card 87. The card 87 contacts the screw 83.

When the rotating rod 52 rotates, it can drive the driven disc to rotate, thereby driving the ball 56 to move. Under the pressure of the inner wall of the hole 54, the ball 56 pushes the elastic block 55 to deform, and finally the ball 56 is disengaged from the hole 54. Under the action of force, the ball 56 slides along the surface of the left fixed plate 51. When the ball 56 slides into the next hole 54, the elastic block 55 restores its deformation, thereby pushing the ball 56 to insert into the hole 54, limiting the rotating rod 52, and thus positioning the sealing disc 53 for use.

[0028] The servo motor 82 is started to drive the output shaft to rotate, which in turn drives the screw 83 to rotate. With the threaded connection, the movable piece 84 can be driven to slide along the inner wall of the slide groove 81 to ensure the stable movement of the movable piece 84. When the movable piece 84 moves, it can drive the mounting piece 85 to move, which in turn drives the roller 86 to move. Finally, the roller 86 contacts the ground and lifts the support frame 2, base 1, etc. Under the action of the roller 86, it is easy to push the base 1, etc. to move and adjust the position of the plastic extrusion mold.
