Description

Technical Field

[0001] The utility model relates to the technical field of plastic particle feeding, in particular to a feeding device for plastic particle production. Background Art

[0002] Plastic particle production feeding is a complex and crucial process. Measures such as reasonably selecting the type of feeder, optimizing the design and maintenance of the feeding system, and solving common problems are required to ensure the stability and efficiency of feeding. Therefore, a feeding device for plastic particle production is needed.

[0003] The Chinese patent with the patent publication number CN208775932U discloses a continuous feeding device for plastic particle production. The device can store materials through a storage box, quantitatively collect materials by the cooperation between a cylinder body and blades, and realize the rotation of the materials. The cooperation with a blanking pipe can realize the blanking work of the materials, and the materials are conveyed out through a discharge pipe. The overall structure of the device is simple and easy to operate. However, although the cooperation between the cylinder body and the blades can complete the rotation of the materials, the materials are prone to accumulate in the cylinder body during the blanking process, and the opening of the blanking pipe is not large, so part of the materials will remain in the cylinder body on both sides of the blanking pipe. Moreover, there is no screening of the material particles in this device, and some particles are relatively large, which are prone to blockage when passing through the connecting pipe and the blanking pipe. Therefore, a feeding device for plastic particle production is proposed. Summary of the Invention

[0004] The purpose of the utility model is to solve the defects existing in the prior art, and a feeding device for plastic particle production is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

A blanking hopper is installed inside the device body, and a filter material bin is connected to the blanking hopper. A filter plate and a wall plate are rotatably connected to the filter material bin. A material taking door is arranged on the outer side of the wall plate. A first motor is connected to one side of the filter material bin. An outer shell is also arranged inside the device body, and a rotating piece is movably connected inside the outer shell. A discharge port is arranged at the bottom side of the outer shell.

[0007] Preferably, the support frame is installed on the outer side of the device body, one end of the support frame is connected to the inside of the device body, the conveyor belt is installed between the inner walls of the support frame, and the conveyor belt is located at the bottom side of the discharge port.

[0008] Preferably, one side of the hopper is fixedly installed on the inner wall of the device body. The bottom side of the hopper is arc-shaped, and a vertical slot is formed at the bottom side of the hopper. A tapered block is installed at the bottom side of the slot.

[0009] Preferably, support blocks are symmetrically installed on both sides of the filter media bin. The support block includes a housing, a moving spring, and a pressing block. The housing is fixedly installed on the inner walls on both sides of the device body. One end of the pressing block is fixedly installed on the filter media bin, and the other end is connected inside the housing. The moving spring is connected between the housing and the pressing block. The first motor is a vibration motor and is installed on the device body. The output end of the first motor is connected to the filter media bin. A feed pipe is fixedly installed on the top surface of the device body. A feed inlet is provided on the top surface of the filter media bin. The bottom end of the feed pipe is connected inside the feed inlet. A limiting piece is fixed on the bottom end of the feed pipe, and the limiting piece is connected to the bottom side opening of the feed inlet.

[0010] Preferably, wall grooves are formed on both sides of the filter media bin. A rotating roller is rotatably connected between the wall grooves. There are two groups of filter plates and wall plates. The filter plate is vertically installed at one end of the wall plate. The rotating roller is fixed at the right-angle connection of the filter plate and the wall plate. One end of the rotating roller extends to the outside of the filter media bin, and a positioning nut is connected thereto. The filter plate and the wall plate are rotatably connected in the wall groove. The wall plate is adapted to the wall groove. The two filter plates are adapted to each other.

A material dropping port is installed on the top surface of the upper outer shell. The discharge port and the material dropping port are on the same horizontal line.

[0012] The beneficial effects of the present utility model are as follows:

[0013] In this solution, the connection between the feed pipe and the filter media bin can avoid the collision between the two during the vibration process. The continuous oscillation of the filter media bin is realized through the first motor. The position of the filter media bin can be stabilized by using the support block and the protective spring. And the filter plate can roughly filter the material. By rotating the wall plate, the filter plate can be rotated to facilitate the removal of unqualified particles. The cooperation between the outer shell and the rotating piece can avoid the accumulation of particulate matter in the outer shell.

A feed pipe 7 is fixedly installed on the top surface of the device body 1. A feed inlet is arranged on the top surface of the filter material bin 8. The bottom end of the feed pipe 7 is connected to the feed inlet. A limiting piece is fixed at the bottom end of the feed pipe 7. The limiting piece is connected to the bottom side of the feed inlet to prevent the collision between the feed pipe 7 and the feed inlet during the vibration process and ensure that all the materials can fall into the filter material bin 8.

[0027] In this embodiment, wall grooves are provided on both sides of the filter media bin 8 to facilitate material extraction on both sides. Rotating rollers are rotatably connected between the wall grooves to facilitate adjusting the position of the filter plate 12. There are two groups of filter plates 12 and wall plates 13.

The discharge port 16 and the material dropping port 17 are on the same horizontal line to enable simultaneous loading and unloading.

[0029] Working principle: Pour the material particles from the feed pipe 7, and the materials will enter the filter media bin 8. At this time, control the first motor 5 to operate, and the filter media bin 8 will vibrate, and the materials will not accumulate on the filter plate 12, thus achieving the effect of rapid filtration. The qualified particles will fall into the lower hopper 11 through the filter plate 12, and the particles with a large volume will remain on the filter plate 12. The materials falling into the lower hopper 11 will fall into the outer shell 9 through the material dropping port 17 and then be concentrated between the two rotating vanes 10. When the materials in this area are full, control the second motor 6 to rotate for material dropping at another position. When the full material area rotates to the bottom side of the outer shell 9, the internal particles will fall on the conveyor belt 2 through the material dropping port 17 and then be conveyed out of the device;
