Description
Technical Field
[0001] The utility model relates to the technical field of feeding devices, in particular to a feeding device which can prevent particles from overflowing when being fed. Background Art
[0002] Plastic products generally use plastic granules as raw materials. When transporting plastic granules, due to their own characteristics, the weight of plastic is relatively light. At the same time, due to the material problem of plastic granules, static electricity is easily generated, which makes the plastic easy to scatter and overflow during transportation. Therefore, when transporting plastic granules, a pneumatic feeder is generally used, that is, a high-pressure blower is used to blow the plastic into the corresponding hopper;
[0003] Since the pneumatic feeder needs to transport plastics, the high-pressure blower is located close to the hopper, so that there is enough wind force inside the transport pipe to blow the plastics away. The hopper is generally open, and the hopper is close to the high-pressure blower, so that the plastic particles inside the hopper are easily blown to the outside of the hopper by the high-pressure blower. At the same time, the feeding speed of the hopper cannot be controlled, which makes it easy for the plastic particles to be blocked inside the transport pipe, thereby shortening the transportation distance of the plastic particles.
[0004] In view of the above situation, we propose a feeding device that prevents particles from overflowing when adding. Utility Model Content
[0005] The utility model aims to solve the shortcomings in the prior art and proposes a feeding device which can prevent particles from overflowing when being added.
[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0007] A feeding device for preventing particles from overflowing when being added, comprising a high-pressure fan, wherein the output end of the high-pressure fan is fixedly connected to a transport pipe, the end of the transport pipe away from the high-pressure fan is fixedly connected to a hopper, the outer surface of the transport pipe above the end near the high-pressure fan is fixedly connected to a speed limiting frame, the inner wall of the speed limiting frame is rotatably connected to a rotating feed plate cocentric with the speed limiting frame, and the inner wall of the speed limiting frame is in contact with the edge of the rotating feed plate;
[0008] The upper outer surface of the speed limit frame is fixedly connected to a feed hopper, the inner walls on both sides of the upper side of the feed hopper are fixedly connected to limit plates, a splash plate rotatably connected to the inner wall of the feed hopper is arranged below the limit plate, a torsion spring is arranged between the splash plate and the limit plate, one end of the torsion spring is connected to the limit plate, and the other end of the torsion spring is connected to the outer surface of the limit plate;
[0009] The material holding hopper is located above the end of the transport pipe away from the high-pressure fan and is fixedly connected to a splash-proof frame on its outer surface, a buffer plate is slidably connected inside the splash-proof frame, a spring is fixedly connected to the side of the buffer plate away from the transport pipe, an end of the spring away from the transport pipe is fixedly connected to the inner wall of the splash-proof frame, and a cushion is fixedly connected to the inner wall of the splash-proof frame above the buffer plate.
[0010] Preferably, brackets are fixedly connected to both sides of the hopper, a bottom end of the bracket is fixedly connected to a bottom plate, the bottom of the bottom plate is fixedly connected to the high-pressure fan, and the bottom of the bottom plate is fixedly connected to the transport pipe by bolts.
[0011] Preferably, a connecting frame is fixedly connected to the top of the base plate, and a servo motor is fixedly connected to the top of the connecting frame.
[0012] Preferably, both ends of the rotating feed plate pass through the speed limit frame, and the top end of the rotating feed plate is fixedly connected to the output end of the servo motor.
[0013] Preferably, a discharge pipe is fixedly connected to the bottom end of the hopper, a discharge plate is rotatably connected inside the discharge pipe, one end of the discharge plate is laterally rotatably connected to the discharge pipe, and a handle is fixedly connected to the outer surface of the discharge plate.
[0014] Preferably, the transport pipe is in an "L" shape, and is used to transport plastic particles from bottom to top.
[0015] The utility model proposes a feeding device for preventing particles from overflowing when adding materials. The beneficial effect is that when in use, the weight of the plastic particles can press the splash plate downward, so that the plastic particles can flow into the interior of the feed hopper. When the plastic particles completely enter the interior of the feed hopper, the splash plate will be driven to reset by the torsion spring, so that the splash plate can block the entrance of the feed hopper, preventing the plastic particles on the inner wall of the feed hopper from being blown up by the wind of the high-pressure fan and splashing out to the outside of the feed hopper. The surface of the splash plate is set to a slope shape. When the plastic is lighter, the plastic particles can also fall along the slope into the interior of the feed hopper. At the same time, the servo motor can set the rotation speed of the output end, thereby controlling the speed at which the rotating feed plate rotates to drive the plastic particles to enter the transport pipe below, so that the high-pressure fan can quickly drive the plastic particles inside the transport pipe to be transported, preventing the plastic particles from piling up under the feed hopper.

[0024] The transport pipe 3 is in an "L" shape and is used to transport plastic particles from bottom to top. The outer surface of the transport pipe 3 near the upper end of the high-pressure blower 1 is fixedly connected to a speed limit frame 10. The inner wall of the speed limit frame 10 is rotatably connected to a rotating feed plate 11 cocentric with the speed limit frame 10.

[0025] The outer surface of the hopper 4 located above the end of the transport pipe 3 away from the high-pressure blower 1 is fixedly connected to a splash-proof frame 14, and a buffer plate 16 is slidably connected inside the splash-proof frame 14.
