Description

Technical Field

[0001] This utility model relates to the field of plastic particle production technology, and more specifically, to a feeding guide device for plastic particle production. Background Technology

[0002] In the production of plastic pellets, hoppers are typically used for temporary storage and guidance to achieve buffering and stable material transport. Common hoppers are often one-piece structures with a square cylinder at the top and a conical hopper at the bottom. This structure is designed to use the conical bottom to gather the material and guide it to the discharge port below.

[0003] However, when plastic particles flow downwards, they are very prone to forming a "bridging" phenomenon in the narrow part of the conical bucket due to mutual compression and hooking. Once a bridging is formed, the material above cannot fall smoothly, resulting in a logistics interruption. This not only causes subsequent production equipment to run out of material and affect continuous production, but in severe cases, it may even require machine shutdown for manual unblocking, reducing production efficiency and stability. Utility Model Content

[0004] The purpose of this invention is to provide a feeding guide device for the production of plastic particles, so as to solve the problems mentioned in the background art. When plastic particles flow downwards, they are very likely to form a "bridging" phenomenon in the narrow part of the conical bucket due to mutual compression and hooking, which can cause material shortage in subsequent production equipment and affect continuous production.

[0005] To address the above problems, the present invention aims to provide a feeding and guiding device for plastic particle production, comprising a hopper. Near the bottom of the hopper, a plurality of movable slots are arranged in a circular array. An inclined guide plate is hinged to the outer wall of the hopper at a position corresponding to each movable slot. The lower end of the guide plate passes through the corresponding movable slot and extends into the hopper. A swinging assembly is mounted on the hopper. A main shaft is rotatably mounted inside the hopper, and a crushing assembly is mounted on the main shaft, positioned above the guide plates. When the main shaft rotates, it drives the crushing assembly to crush the agglomerated plastic particles in the hopper. Simultaneously, the main shaft drives the swinging assembly, causing all guide plates to swing synchronously around their respective hinge axes.

[0006] As a further improvement to this technical solution, the swing assembly includes a square frame that is slidably sleeved on the hopper, and the square frame is located above the guide plate. The bottom of the square frame is hinged with an inclined connecting rod at a position corresponding to each guide plate, and the other end of the connecting rod is hinged to the side of the guide plate near the hopper.

[0007] As a further improvement to this technical solution, the swing assembly also includes two reciprocating mechanisms. Each reciprocating mechanism includes a mounting frame fixedly installed on the outer wall of the hopper. A sleeve frame is vertically slidably installed inside the mounting frame. An extension frame is fixedly installed at the bottom of the sleeve frame, and the lower end of the extension frame is fixedly connected to the square frame.

[0008] As a further improvement to this technical solution, an eccentric wheel is provided inside the sleeve frame, and the end of the main shaft rotates through the hopper and is fixedly connected to the eccentric wheel.

[0009] As a further improvement to this technical solution, sliders are fixedly installed on both sides of the sleeve frame, and a groove is opened on the mounting bracket at the position corresponding to each slider, and the slider is slidably installed in the corresponding groove.

[0010] As a further improvement to this technical solution, the crushing component includes two arc-shaped plates integrally formed on both sides of the hopper, the axis of the arc-shaped plates being collinear with the axis of the main shaft, and a plurality of crushing rods being fixedly installed on the main shaft.

[0011] As a further improvement to this technical solution, a number of vertically arranged guide rods are fixedly installed in a ring array on the hopper, and a sleeve is fixedly installed on the frame at the position corresponding to each guide rod, and the sleeve is slidably sleeved on the corresponding guide rod.

[0012] As a further improvement to this technical solution, a speed reducer is fixedly mounted on one of the mounting brackets. The output shaft of the speed reducer is coaxially and fixedly connected to the main shaft. A servo motor is fixedly mounted on the speed reducer. The output shaft of the servo motor is coaxially and fixedly connected to the input shaft of the speed reducer.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The feeding guide device for producing plastic particles drives the crushing rod to rotate via the main shaft, breaking up the clumps of plastic particles in the hopper to prevent blockage. Simultaneously, the main shaft drives the oscillating component to move, causing the frame to reciprocate vertically under the guidance of the guide rod. This, in turn, drives all the guide plates to oscillate synchronously around the hinge point via the connecting rod. The guide plates switch between periodically opening and closing states: when open, they expand the material drop channel space, promoting the rapid passage of plastic particles; when closed, they guide the particles and slightly compact them, effectively disrupting the formation of particle bridging in the hopper. This ensures that the plastic particles are continuously and stably discharged from the outlet, avoiding "mouse hole" or flow deviation phenomena, and guaranteeing a smooth and uniform feeding process.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example 1 Please see Figure 1 As shown, the purpose of this embodiment is to provide a feeding guide device for the production of plastic particles, including a hopper 1. The hopper 1 is composed of an upper square cylindrical section and a bottom conical hopper, and the whole is a cylindrical structure that runs through the top and bottom. The upper opening of the hopper 1 serves as the feeding port, and the lower opening serves as the discharging port.

[0018] Reference Figure 2 and Figure 3The conical bucket section near the bottom of the hopper 1 has several movable slots 12 arranged in a ring. The outer wall of the hopper 1 is hinged with an inclined guide plate 2 at the position corresponding to each movable slot 12. The guide plate 2 is designed as an approximately trapezoidal plate structure with a thinner top and a thicker bottom. The side away from the hopper 1 has a weight-reducing slot to reduce its own weight. The bottom of the guide plate 2 is hinged to the hopper 1 above the movable slot 12. The lower end of the guide plate 2 passes through the corresponding movable slot 12 and extends into the hopper 1. All the guide plates 2 together form a material discharge channel with a variable cross section. The hopper 1 is equipped with a swing assembly, which is used to drive all the guide plates 2 to swing synchronously around their respective hinge axes.

[0019] The hopper 1 is equipped with a rotating main shaft 3, which is equipped with a crushing component located above the guide plate 2. The external conveying equipment feeds plastic particles into the hopper 1 through the feed inlet. During operation, the main shaft 3 starts to rotate, and the main shaft 3 drives the crushing component to crush the agglomerated plastic particles in the hopper 1. At the same time, the main shaft 3 drives the swing component, which causes all the guide plates 2 to swing synchronously around their respective hinge axes, thereby changing the tilt angle of the guide plates 2.

[0020] During the synchronous reciprocating oscillation of the guide plates 2, the distance between adjacent guide plates 2 changes periodically: when the distance increases, the guide plates 2 are in an open state, making more space for the lower outlet area and facilitating the passage of more plastic particles; when the distance decreases, the guide plates 2 turn into a closed state, guiding the passing plastic particles and applying a slight compaction effect. Through this periodic opening and closing action, not only can bridging of plastic particles within the conical hopper be effectively prevented, but also a stable and uniform material flow can be promoted, thereby avoiding "mouse holes" or flow deviation.

[0021] It should be noted that the guide plate 2 always blocks the bottom of the movable trough 12 during the swinging process. Even when the guide plate 2 is in the open state and an opening appears between the guide plate 2 and the top side of the movable trough 12, the inclined structure of the guide plate 2 can still effectively guide the plastic particles and ensure that the plastic particles will not leak to the outside of the hopper 1 through the opening. To further enhance the sealing effect, a dustproof cloth cover can be installed between the hopper 1 and the guide plate 2 to wrap the guide plate 2 and the outside of the opening, thereby preventing the leakage of dust formed by tiny particles in the plastic particles.

[0022] The structure of the oscillating component is detailed below, referring to... Figure 3 and Figure 4The oscillating component includes a square frame 4 that is slidably fitted onto the hopper 1, and the square frame 4 is located above the guide plate 2. In order to achieve stable guiding movement of the square frame 4, several vertically arranged guide rods 13 are fixedly installed in a ring array on the hopper 1. A sleeve is fixedly installed on the square frame 4 at the position corresponding to each guide rod 13. The sleeve is slidably fitted onto the corresponding guide rod 13, thereby restricting the square frame 4 to move only in the vertical direction. In order to prevent dust accumulation from affecting the movement, a protective cover can be installed on the outside of the hopper 1 to completely wrap the square frame 4, the sleeve and the guide rod 13, and prevent dust from falling on the moving parts. An inclined connecting rod 5 is hinged to the bottom of the square frame 4 at the position corresponding to each guide plate 2. The other end of the connecting rod 5 is hinged to the side of the guide plate 2 near the hopper 1. The protective cover has a through groove at the position corresponding to the connecting rod 5 to ensure that the connecting rod 5 is not interfered with during the movement.

[0023] The oscillating assembly also includes two reciprocating mechanisms 6. The structure of the reciprocating mechanisms 6 is described in detail below, referring to... Figure 5 and Figure 6 The reciprocating mechanism 6 includes a mounting frame 61 fixedly installed on the outer wall of the hopper 1. A sleeve frame 63 is vertically slidably installed inside the mounting frame 61. An extension frame 64 is fixedly installed at the bottom of the sleeve frame 63. The lower end of the extension frame 64 is fixedly connected to the square frame 4. An eccentric wheel 62 is provided inside the sleeve frame 63. The end of the main shaft 3 rotatably passes through the hopper 1 and is fixedly connected to the eccentric wheel 62. In order to restrict the sleeve frame 63 to move only in the vertical direction, sliders 66 are fixedly installed on both sides of the sleeve frame 63. A groove 65 is opened on the mounting frame 61 at the position corresponding to each slider 66. The slider 66 is slidably installed inside the corresponding groove 65.

[0024] When the main shaft 3 rotates, it drives the eccentric wheel 62 to rotate. The rotating eccentric wheel 62 continuously pushes the sleeve 63 to make vertical reciprocating motion. The sleeve 63 drives the square frame 4 to move up and down synchronously through the extension frame 64. When the square frame 4 moves upward, it drives the guide plate 2 to rotate upward through the connecting rod 5, so that it is in the closed state. When the square frame 4 moves downward, it drives the guide plate 2 to rotate downward, so that it is in the open state, thereby realizing the periodic switching of the state of the guide plate 2.

[0025] To drive the spindle 3 to rotate, a reducer 7 is fixedly mounted on one of the mounting brackets 61. The output shaft of the reducer 7 is coaxially and fixedly connected to the spindle 3. A servo motor 8 is fixedly mounted on the reducer 7. The output shaft of the servo motor 8 is coaxially and fixedly connected to the input shaft of the reducer 7. When the servo motor 8 starts, the output shaft of the servo motor 8 drives the input shaft of the reducer 7 to rotate. After speed reduction and torque increase, the output shaft of the reducer 7 drives the spindle 3 to rotate.

[0026] The following details the structure of the crushing component, refer to... Figure 2 and Figure 5The crushing component includes two arc-shaped plates 11 integrally formed on both sides of the hopper 1. The axis of the arc-shaped plates 11 is collinear with the axis of the main shaft 3. Several crushing rods 31 are fixedly installed on the main shaft 3. The arc-shaped plates 11 provide sufficient rotation space for the crushing rods 31. When the main shaft 3 rotates, the main shaft 3 drives all the crushing rods 31 to rotate synchronously. The crushing rods 31 break up the clumps of plastic particles in the hopper 1. The crushed plastic particles are smoothly discharged from the hopper 1 through the discharge channel, preventing the clumps from forming bridges in the discharge channel and ensuring that the plastic particles fall smoothly from the discharge port into the predetermined channel or container for subsequent production processing.

[0027] When in use, the main shaft 3 drives the crushing rod 31 to rotate, breaking up the clumps of plastic particles in the hopper 1 to prevent blockage. At the same time, the main shaft 3 drives the swing assembly to move, causing the frame 4 to make vertical reciprocating motion under the guidance of the guide rod 13. Then, the connecting rod 5 drives all the guide plates 2 to swing synchronously around the hinge point. The guide plates 2 switch between periodically opening and closing: when opening, they expand the material drop channel space and promote the rapid passage of plastic particles; when closing, they guide the particles and slightly compact them, thereby effectively breaking the formation of particle bridging in the hopper 1 and ensuring that plastic particles are continuously and stably discharged from the outlet.
