DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Embodiment 1

[0021] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 The utility model provides a technical solution: a plastic powder feeder, including a spiral feeder 1, characterized in that: a fixed ring 10 is fixedly connected to the outer wall of one end of the spiral feeder 1, a rotating plate 3 is rotatably connected to one end of the spiral feeder 1, a support plate 2 is fixedly connected to one end of the rotating plate 3, a threaded rod 8 is rotatably connected to the upper surface of the support plate 2, a slider 7 is slidably connected to the outer wall of the threaded rod 8, a connecting rod 11 is rotatably connected to the upper part of the slider 7, the connecting rod 11 is rotatably connected to the lower part of the fixed ring 10, and one end of the spiral feeder 1 is fixedly connected to A fixed plate 17 is connected, a sliding plate 15 is slidably connected to the lower part of the fixed plate 17, a support frame 4 is rotatably connected to the lower part of the rotating plate 3, a second motor 9 is fixedly connected to one end of the support plate 2, a threaded rod 8 is fixedly connected to the second motor 9, a limiting plate 16 is fixedly connected to the upper part of the sliding plate 15, the limiting plate 16 is slidably connected to the inside of the fixed plate 17, a return spring 19 is fixedly connected to one end of the limiting plate 16, the other end of the return spring 19 is fixedly connected to one side of the fixed plate 17, and the other end of the limiting plate 16 is fixedly connected to the rack 14.

[0022] Based on the working principle of the plastic powder feeder of Example 1, when it is desired to feed plastic product processing machines of different heights, the threaded rod 8 is driven to rotate by starting the second motor 9, and the rotation of the threaded rod 8 causes the slider 7 slidably connected to the outer wall of the threaded rod 8 to move. When it is desired to lift the spiral feeder 1, the threaded rod 8 drives the slider 7 to move in the direction of the second motor 9. At this time, the slider 7 will push against the connecting rod 11, forcing the spiral feeder 1 connected to the rotating plate 3 to be lifted. When it is desired to lower it, the slider 7 can be moved away from the second motor 9. Since the rotating plate 3 is rotatably connected to the top of the support frame 4, the spiral feeder 1 can also be rotated 360 degrees to adjust to a suitable position.

[0023] Embodiment 2

[0024] See also Figure 1 , Figure 2 , Figure 3 , Figure 4Compared with the first embodiment, the present invention proposes a plastic powder feeder, and the present embodiment further includes: a third motor 12 is fixedly connected to the top of the fixed plate 17, a half gear 13 is fixedly connected to the output end of the third motor 12, a rack 14 is meshed with the half gear 13, a leakage groove 18 is provided at the center of the sliding plate 15, a heating device 21 is fixedly connected to one end of the fixed plate 17, a feed hopper 6 is provided at one end of the spiral feeder 1, a rotating fin 20 is rotatably connected to the inside of the spiral feeder 1, and a first motor 5 is fixedly connected to one end of the spiral feeder 1, and the first motor 5 passes through the spiral feeder 1 and is fixedly connected to the rotating fin 20.

[0025] The working principle of the plastic powder feeder based on the second embodiment is: the third motor 12 rotates to drive the half gear 13, and the rack 14 meshing with the half gear 13 moves. Since the rack 14 is fixedly connected to one end of the limit plate 16, it will compress the reset spring 19 to push the limit plate 16 toward one end of the discharge port. A leakage groove 18 is provided on the sliding plate 15. The size of the leakage groove 18 is consistent with the size of the discharge end of the spiral feeder 1. Under the push of the rack 14, the leakage groove 18 and the spiral The discharge end of the feeder 1 is aligned, and the heating device 21 heats the plastic powder at the discharge port of the spiral feeder 1. When the leakage chute 18 is aligned with the discharge end of the spiral feeder 1, the preheated plastic powder will fall from the leakage chute 18. When the half gear 13 rotates to a toothless position, the rack 14 is no longer engaged. At this time, the reset spring 19 will push the limit plate 16 to reset, so that the sliding plate 15 blocks the discharge end of the spiral feeder 1 again, allowing the heating device 21 to preheat the plastic powder again.

[0026] The above-mentioned specific embodiments are only several preferred embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
