Description

Technical Field

[0001] This utility model relates to the field of plastic granule processing equipment, and more specifically, to an automatic feeding mechanism for plastic granules. Background Technology

[0002] A plastic granule feeding mechanism is a device used for the automated conveying and processing of plastic granules. It plays a crucial role in the plastic processing production process by transporting plastic granules from storage devices to subsequent processing stages.

[0003] However, during use, it cannot effectively optimize the treatment of dust and impurities in plastic granules.

[0004] Therefore, there is an urgent need for an automatic plastic pellet feeding mechanism that can facilitate the separation of impurities from plastic pellets. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an automatic feeding mechanism for plastic granules to solve the technical defects existing in the background technology.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: An automatic plastic granule feeding mechanism includes a base plate. A drive frame is located on the left side of the upper surface of the base plate. A hopper base is connected to the right side of the drive frame. A feed hopper is installed above the hopper base. A discharge frame is located on the right side of the hopper base. The right side of the discharge frame is open and equipped with a movable baffle. A downwardly inclined feeding mechanism is connected to the right side of the discharge frame. The feeding mechanism includes a screen plate. Protective plates are provided on both sides of the screen plate. Multiple arc-shaped holes are opened on the surface of the screen plate. A convex plate fits into each arc-shaped hole. The convex plate and the arc-shaped hole are interference-fitted. A branch pipe is connected between adjacent convex plates. Two branch pipes are provided, and their ends pass through the convex plates and are connected to through pipes. A collection frame is installed below the screen plate. A dust collection box connected to the through pipe is provided on the lower surface of the collection frame. A discharge port is provided in the middle of the collection frame and is fitted with a removable cover.

[0007] As a further embodiment of this utility model, the upper and lower surfaces of the mesh plate are respectively covered with antistatic material. The antistatic material on the upper and lower surfaces of the mesh plate prevents the plastic particles from generating static electricity due to friction, avoids the particles adhering to the mesh plate or the convex plate (affecting the conveying efficiency), and at the same time reduces the risk of dust explosion caused by static electricity (plastic dust is flammable).

[0008] As a further embodiment of this utility model, the cross-sectional shape of the arc-shaped hole and the convex plate is consistent, both being wavy structures, which can increase the contact area between the particles and the convex plate and improve the diversion effect.

[0009] As a further embodiment of this utility model, the portion of the convex plate exposed above the mesh plate has a triangular structure. The interior of the convex plate is hollow and mesh holes are opened on both sides to enhance the dust collection capacity and ensure that the dust generated by particle collision can enter the interior of the convex plate efficiently and then be discharged through the branch pipe.

[0010] As a further embodiment of this utility model, the dust collection box is equipped with a dust suction device inside, which works in conjunction with the through pipe to provide power to the dust collection box, ensuring that dust can be actively drawn into the dust collection box from the convex plate through the branch pipe and the through pipe, thus avoiding dust accumulation in the pipe.

[0011] As a further embodiment of this utility model, the material collection frame and the mesh plate are installed in a movable and detachable manner. The material collection frame is provided with buckle plates on both sides, and the mesh plate is provided with buckle grooves at corresponding positions to facilitate regular cleaning of residual particles or dust in the material collection frame and reduce maintenance difficulty. Beneficial effects

[0012] Compared with a traditional automatic feeding mechanism for plastic granules, this utility model has the following advantages: The inclined mesh plate and convex plate of this utility model can divert plastic particles during the feeding process to avoid their accumulation and ensure smooth conveying. At the same time, the mesh structure on the surface of the convex plate can suck up the dust generated between the plastic particles during the feeding process and transport it into the dust collection box.

[0013] Meanwhile, antistatic material is laid on both the upper and lower surfaces of the mesh plate to prevent plastic particles from generating static electricity due to friction, thus avoiding particles adhering to the mesh plate or convex plate (affecting conveying efficiency). At the same time, it reduces the risk of dust explosion caused by static electricity (plastic dust is flammable). Attached Figure Description

Detailed Implementation

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] like Figures 1-2 As shown, this utility model provides a technical solution for an automatic plastic granule feeding mechanism: As shown in the figure, an automatic plastic granule feeding mechanism includes a base plate 1. A drive frame 2 is disposed on the left side of the upper surface of the base plate 1. A hopper base 3 is connected to the right side of the drive frame 2. A feed hopper 4 is installed above the hopper base 3. A discharge frame 5 is disposed on the right side of the hopper base 3. The discharge frame 5 is open on the right side and has a movable baffle 6 installed thereon. A downwardly inclined feeding mechanism 7 is connected to the right side of the discharge frame 5. The feeding mechanism 7 includes a screen plate 71. Guard plates 72 are disposed on both sides of the screen plate 71. Multiple arc-shaped holes 73 are opened on the surface of the mesh plate 71. A convex plate 74 is fitted into the arc-shaped hole 73. The convex plate 74 and the arc-shaped hole 73 are in an interference fit. A branch pipe 75 is fitted between adjacent convex plates 74. Two branch pipes 75 are provided, and their ends pass through the convex plates 74 and are connected to a through pipe 76. A material collection frame 77 is installed below the mesh plate 71. A dust collection box 78 connected to the through pipe 76 is provided on the lower surface of the material collection frame 77. A discharge port 79 is provided in the middle of the material collection frame 77. The discharge port 79 is fitted with a removable cover.

[0018] The upper and lower surfaces of the mesh plate 71 are covered with antistatic material to prevent plastic particles from generating static electricity due to friction, thus avoiding particles adhering to the mesh plate or convex plate (affecting conveying efficiency), and reducing the risk of dust explosion caused by static electricity (plastic dust is flammable).

[0019] The arc-shaped hole 73 and the convex plate 74 have the same cross-sectional shape, both being wavy structures, which can increase the contact area between the particles and the convex plate and improve the diversion effect.

[0020] The portion of the convex plate 74 exposed above the mesh plate 71 has a triangular structure. The interior of the convex plate 74 is hollow and has mesh openings on both sides to enhance dust collection capabilities and ensure that dust generated by particle collisions can efficiently enter the interior of the convex plate and then be discharged through the branch pipe.

[0021] The dust collection box 78 is equipped with a dust suction device, which works in conjunction with the through pipe 76 to provide power to the dust collection box and ensure that dust can be actively drawn into the dust collection box from the convex plate through the branch pipe and through pipe, thus preventing dust from accumulating in the pipe.

[0022] The material collection frame 77 and the mesh plate 71 are installed in a movable and detachable manner. The material collection frame 77 is provided with buckle plates on both sides, and the mesh plate 71 is provided with buckle grooves at corresponding positions to facilitate regular cleaning of residual particles or dust in the material collection frame and reduce maintenance difficulty.

[0023] The specific implementation principle is as follows: Plastic granules are first poured into the feed hopper 4 for storage. The granules fall to the hopper base 3 below by their own gravity. The drive frame 2 provides power, such as a motor-driven conveying roller or pushing device, to push the granules in the hopper base to the discharge frame 5. The movable baffle 6 can control the output of granules by adjusting the size of the opening, so as to avoid blockage of subsequent links due to excessive instantaneous discharge. After the granules enter the inclined feeding mechanism 7 from the discharge frame 5, they slide down the surface of the mesh plate 71 under the action of gravity. During the sliding process, the plastic granules collide and rub against the convex plate 74, the mesh plate 71 and other granules, generating dust. The dust is sucked into the inner control cavity by the mesh on the surface of the convex plate 74. At the same time, the fine impurities inside the plastic granules during the feeding process will fall down the mesh plate 71 into the collection frame 77, while the dust is absorbed into the dust collection box 78 under the action of the convex plate 74.

[0024] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
