Specifically, the main function of the first transmission part and the second transmission part is to control the different rotation speeds of the inlet guide plate 2 and the refining rake 3 through the transmission ratio. In this embodiment, when the baffle plate 5 pushes the driving rod 8.2 to move forward, the inlet guide plate 2 and the refining rake 3 rotate synchronously, and the rotation speed of the refining rake 3 is greater than that of the inlet guide plate 2. For example, in this embodiment, the angle of rotation of the inlet guide plate 2 is 20 °, the angle of rotation of the refining rake 3 is 180 °, and the angle between the outermost rake bar 3.2 and the horizontal plane is 45 °. At this time, when the inlet guide plate 2 rotates by 9 degrees, the outermost rake rod 3.2 is just in a horizontal state, and at this time, the outer end of the outermost rake rod 3.2 is located above the feeding conveyor belt 4 in the height direction, and the position where the outermost rake rod is located can better press down barrel-shaped plastic raw materials.
Secondly, the driving ratchet bar 8.3 is arranged in a state that the ratchet part of the driving ratchet bar is telescopic and is supported on the main body part by the ratchet spring, when the driving ratchet bar 8.3 moves forwards, the driving ratchet gear 8.5 is driven to rotate, and when the driving ratchet bar 8.3 moves reversely and is restored under the action of the restoring spring 8.4, the driving ratchet gear 8.5 is locked by the unidirectional ratchet 8.6 and cannot rotate reversely, so that the ratchet part of the driving ratchet bar 8.3 moves downwards and compresses the ratchet spring to pass over the driving ratchet gear 8.5 and is restored.
More specifically, in the embodiment of the present invention, the driving mechanism 8 is actuated once during the movement of the striker plate 5 to the initial position overlapping the circular arc portion of the discharge end of the feed conveyor belt 4 to the circular arc trajectory line where the outer end of the striker plate 5 is located when it swings tangential to the entrance guide 2 during the swing movement.
At this time, since the striker plate 5 is located at the initial position overlapping the circular arc portion of the discharge end of the feed conveyor 4 when the driving mechanism 8 is operated, all the plastic raw material in front of the striker plate 5 can enter the entrance guide 2 before the entrance guide 2 rotates.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
