Description

Technical Field

[0001] This utility model relates to the field of plastic product processing, specifically to a masterbatch screening and dispensing device. Background Technology

[0002] Plastic products are widely used in people's lives, and their application in various aspects of life is particularly common. In the production process of plastic products, the raw materials are generally small pieces of plastic in granular form. These small granules are called masterbatches. The production and processing of masterbatches is the first step in making plastic products. The general processing technology is to melt large pieces of plastic at high temperature into a paste with a certain fluidity, and then extrude the paste into thin strips through an extruder. After cooling and rapid cutting by a rolling cutter, they become small granules of masterbatches. At this time, the masterbatches are generally of uneven size. To standardize the uniformity of the products and the compatibility with various plastic production machines, the uneven size needs to be screened. Classifying and screening the unevenly sized granular masterbatches is the preliminary work for the next step of manufacturing plastic products. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a masterbatch screening and distribution device to solve the problems of uneven masterbatch size affecting the compatibility and consistency of various plastic products.

[0004] The utility model is realized through the following technical solutions:

[0005] A masterbatch screening and dispensing device includes: a support frame, a dispensing plate, a dispensing hole, a gravity guide plate, a spring, a side baffle, a collecting funnel, and reinforcing ribs;

[0006] The support frame is the lower support plate of this masterbatch screening and dispensing device, serving a supporting function. It is a rectangular metal plate structure and is set at both ends and the middle of this device, evenly distributed from the first end to the last end. The height of the support frame also decreases evenly from high to low, forming an inclined plane that forms an angle with the horizontal ground. The multiple support frames are set at intervals to ensure the stability of the equipment. The dispensing plate is a rectangular metal plate structure and is set on the upper end of the support frame. The spaced support frames are assembled into an integral structure through the dispensing plate. Due to the successively decreasing height of the support frames, the front end of the dispensing plate is higher than the rear end of the dispensing plate, so the dispensing plate forms an inclined plane with the horizontal plane, which is conducive to the masterbatch naturally sliding from high to low due to gravity. The upper end of the dispensing plate is provided with dispensing holes and gravity guide plates. The masterbatch falls and is dispensed through the dispensing holes. The gravity guide plates increase the sliding speed after the masterbatch accumulates to a certain weight.

[0007] Preferably, the multiple distribution holes are elongated holes that are arranged throughout the upper surface of the distribution plate, so that the distribution plate is evenly covered with distribution holes, which facilitates the masterbatch to fall into the lower part of the distribution plate through the distribution holes. The specific structure of a single distribution hole is an elongated through-hole structure that gradually widens from narrow. The masterbatch in the initial processing is of uneven size. Through the elongated through-hole structure that gradually widens from narrow to widens, the masterbatch of uneven size is gradually screened and falls into the lower part of the distribution plate.

[0008] Preferably, the gravity guide plate is a thin, lightweight metal strip, which is easy to handle. The gravity guide plate is horizontally mounted on the distribution plate perpendicular to the distribution hole. Several gravity guide plates are spaced apart on the distribution plate. A spring is provided at the lower part of the gravity guide plate. When the spring at the lower end of the gravity guide plate is not in operation, there is no accumulation of masterbatch at the upper part. In this state, the gravity guide plate forms an angle due to the support of the spring, and the tail end of the gravity guide plate is in an upward state. When in operation, the larger volume of masterbatch that has not passed through the narrower distribution hole at the front flows into this area and accumulates. The weight of the accumulated masterbatch increases, causing the spring to contract, and the gravity guide plate descends to fit against the distribution plate. The accumulated masterbatch flows into the next section of the distribution plate, thus achieving the screening of masterbatch size.

[0009] Preferably, the upper end of the spring is disposed on the lower end face of the gravity guide plate, and the lower end of the spring is disposed on the upper end face of the material distribution plate at the gap of the material distribution hole. The accumulation of masterbatch causes the spring to contract, thereby enabling the gravity guide plate to move down and fit against the material distribution plate so that the masterbatch can pass through smoothly.

[0010] Preferably, the side baffle is a plate-shaped structure, and the side baffle is inclinedly arranged on both sides and the rear end of the distribution plate to prevent the masterbatch flowing through the distribution plate from overflowing onto the edge.

[0011] Preferably, the collecting funnel is a funnel-shaped cylindrical structure formed by metal sheet. The upper end of the collecting funnel is set on the lower end face of the distribution plate to collect the masterbatch that has been screened by the distribution holes on the distribution plate. The constriction at the bottom facilitates the collection of masterbatch. Multiple collecting funnels are set at the intervals of adjacent support frames to collect masterbatch of different volumes.

[0012] Preferably, the reinforcing rib metal strip is positioned such that the reinforcing rib is disposed on the inner end face of the support frame, thereby increasing the support strength of the support frame and ensuring the service life of the equipment.

[0013] Beneficial effects: This solution uses a distribution hole that widens from narrow to wide, allowing smaller masterbatches to be collected first through the distribution holes on the distribution plate. Larger masterbatches are accumulated by the gravity guide plate at the rear, and then pressed down to create acceleration for further screening before falling into the designated collection funnel for size classification and collection. By screening masterbatches of different sizes, the system ensures rapid collection of masterbatches while maintaining consistency within the same batch. Masterbatches of different sizes can be adapted to various plastic production machines on the market, while masterbatches of the same size ensure the stable operation of the plastic production machine, reducing the risk of overloading the production machine or even increasing the defect rate of plastic products due to uneven raw material size.

[0020] 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.

[0021] The support frame 1 is the lower support plate of this masterbatch screening and distributing device, which serves as a support. It is a rectangular metal plate structure and is set at both ends and the middle of this device. It is evenly distributed from the first end to the last end of this device. The height of the support frame 1 also decreases evenly from high to low, forming an inclined plane that forms an angle with the horizontal ground. The multiple support frames 1 are set at intervals to ensure the stability of the equipment. The distributing plate 2 is a rectangular metal plate structure and is set on the upper end of the support frame 1. The spaced support frames 1 are assembled into an integral structure through the distributing plate 2. Because the height of the support frame 1 decreases successively, the front end of the distributing plate 2 is higher than the rear end of the distributing plate 2, so that the distributing plate 2 forms an inclined plane with the horizontal plane, which is conducive to the masterbatch naturally sliding from high to low due to gravity. The upper end of the distributing plate 2 is provided with distributing holes 3 and gravity guide plates 4. The masterbatch falls and is distributed through the distributing holes 3. The gravity guide plates 4 increase the sliding speed after the masterbatch accumulates to a certain weight.

[0022] Furthermore, the multiple distribution holes 3 are elongated holes that are arranged throughout the upper surface of the distribution plate 2, so that the distribution plate 2 is evenly covered with distribution holes 3, which facilitates the masterbatch to fall into the lower part of the distribution plate 2 through the distribution holes 3. The specific structure of a single distribution hole 3 is an elongated through hole structure that gradually widens from narrow. The masterbatch in the initial processing is of uneven size. Through the elongated through hole structure of the distribution hole 3, the masterbatch of uneven size is gradually screened and falls into the lower part of the distribution plate 2.

[0023] Furthermore, the gravity guide plate 4 is a thin metal strip, which is lightweight and easy to handle. The gravity guide plate 4 is horizontally mounted on the distribution plate 2 perpendicular to the distribution hole 3. Several gravity guide plates 4 are spaced apart on the distribution plate 2. A spring 5 is provided at the lower part of the gravity guide plate 4. When the spring 5 at the lower end of the gravity guide plate 4 is not working, there is no masterbatch accumulation at the upper part. In this state, the gravity guide plate 4 forms an angle due to the support of the spring 5, and the tail end of the gravity guide plate 4 is in an upward state. When working, the larger volume of masterbatch that has not passed through the narrower distribution hole 3 at the front flows into this and accumulates. The weight of the accumulated masterbatch increases, causing the spring 5 to contract. The gravity guide plate 4 descends and fits against the distribution plate 2. The accumulated masterbatch flows into the next section of the distribution plate 2, thereby achieving the screening of masterbatch size.

[0024] Furthermore, the upper end of the spring 5 is disposed on the lower end face of the gravity guide plate 4, and the lower end of the spring 5 is disposed on the upper end face of the material distribution plate 2 at the gap of the material distribution hole 3. The accumulation of masterbatch causes the spring 5 to contract, thereby enabling the gravity guide plate 4 to move down and fit against the material distribution plate 2 so that the masterbatch can pass through smoothly.

[0025] Furthermore, the side baffle 6 is a plate-shaped structure, and the side baffle 6 is inclinedly arranged on both sides and the rear end of the distribution plate 2 to prevent the masterbatch flowing through the distribution plate 2 from overflowing when it flows into the edge.

[0026] Furthermore, the collecting funnel 7 is a funnel-shaped cylindrical structure formed by metal plates. The upper end of the collecting funnel 7 is set on the lower end face of the distributing plate 2 to collect the masterbatch that has been screened by the distributing hole 3 on the distributing plate 2. The constriction at the bottom facilitates the collection of masterbatch. Multiple collecting funnels 7 are set at the intervals of adjacent support frames 1 to collect masterbatch of different volumes.

[0027] Furthermore, the reinforcing rib 8 is a metal strip, which is set on the inner end face of the support frame 1 to increase the support strength of the support frame 1 and help ensure the service life of the equipment.

[0028] Operating steps: During operation, the support frame is arranged in a descending order of height, forming an inclined structure. The distribution plate covers the backflow masterbatch plane of the support frame platform. The narrow-sided, wide distribution holes allow masterbatch of uneven sizes to fall into the collection funnel under the support frame according to their size. The spring under the gravity guide plate is in the extended state when not under pressure, and the gravity guide plate is tilted upwards towards the distribution plate. The larger masterbatch after diversion falls into the front distribution hole and accumulates here. After accumulating to a certain weight, the spring contracts, and the gravity guide plate is pressed down and adheres to the distribution plate. The accumulated masterbatch enters the next distribution hole for further screening due to gravity acceleration. Through multiple screenings using the above structure, relatively accurate screening and classification of masterbatch of uneven sizes is achieved.
