[0028] Embodiment 2

[0029] The main difference from the first embodiment is:

[0030] A screw feeding device, the bottom of the inner cavity of the discharge trough 3 is fixedly connected with a guide plate 7, the guide plate 7 is provided with two symmetrical pieces, the top of which is an inclined surface, the inside of the guide plate 7 is fixedly connected with a discharge plate 8, the top of the discharge plate 8 is provided with a discharge trough, one end of the discharge plate 8 is fixedly connected to the left side of the material distribution box 412, the feeding mechanism 2 includes a feeding cylinder 21 installed at the bottom of the inner cavity of the support frame 1, the feeding cylinder 21 is connected to the external air source through an air pipe, the top of the feeding cylinder 21 is fixedly connected with a feeding plate 22 through a feeding rod, and the feeding plate 22 is fixedly connected to the bottom of the inner cavity of the support frame 1. The top is an inclined surface, and the surface of the feeding plate 22 is slidably connected to the inside of the discharge trough 3. The feeding plate 22 is a concave plate, and the inner surface of the feeding plate 22 is slidably connected to the surface of the guide plate 7. Driven by the feeding cylinder 21, the concave feeding plate 22 slides back and forth up and down inside the discharge trough 3. Each sliding drives the screw to fall into the slide groove at the top of the discharge plate 8, so that the screw slides toward the dividing box 412 to realize the feeding operation of the screw. At the same time, the contents not described in detail in this specification belong to the existing technology known to technical personnel in this field.

[0031] During operation, first, the feeding cylinder 21 is started to drive the feeding rod and the feeding plate 22 to slide up and down reciprocatingly. The feeding plate 22 pushes the screw inside the discharge trough 3 to the guide plate 7 through the inclined surface at the top. The screw passes through the guide plate 7 and falls into the slide groove at the top of the discharge plate 8. Since the discharge plate 8 is designed to be inclined, the screw will slide on the inner surface of the slide groove at the top of the discharge plate 8, so that the screw slides into the inside of the distribution box 412, and slides to the inner surface of the arc groove 416 through the notch on the left side of the distribution box 412. Then, the driving cylinder 421 is started to drive the piston rod 422 and the sliding plate 413 to slide on the inner wall of the distribution box 412, so that the sliding block 415 slides on the inner surface of the inclined groove 5, and then The two movable plates 414 slide inside the sliding plate 413. When the screw slides to the inner surface of the arc groove 416 on the front side, the sliding block 415 on the top of the front movable plate 414 slides to the center of the inclined groove 5. Then, when the sliding plate 413 slides to the front side, the front movable plate 414 drives the screw to slide synchronously. When the screw slides to the top of the front distribution tube 417, the front movable plate 414 slides to the right inside the sliding plate 413, which makes the surface of the screw contact with the inner wall of the open groove 6 on the top of the distribution box 412, so that the screw disengages from the arc groove 416, and the screw and the front distribution tube 417 fall off, realizing the batch discharging operation of the screw.
