A circular discharge hood is installed at one end of the bottom of each feeding hopper. A motor is installed on one outer wall of the circular discharge hood, and a rotating rod is mounted on the output shaft of the motor. Six equidistant distributing plates are installed on the outer wall of the rotating rod. The outer wall of the distributing plates is fitted with a clearance fit to the inner wall of the circular discharge hood, and the clearance between the distributing plates and the inner wall of the circular discharge hood is less than the minimum particle radius. This utility model achieves linear speed regulation of the distributing plates, allowing the feeding speed to be precisely adjusted according to the bagging capacity requirements. The clearance fit between the six equidistant distributing plates and the inner wall of the circular discharge hood ensures that the material is evenly cut and pushed, avoiding local accumulation or cavities.

Description

Technical Field

[0001] This utility model relates to the field of bagging equipment technology, specifically to a bagging device for modified plastic granules. Background Technology

[0002] Modified plastic granules are an important industrial raw material widely used in the automotive, electronics, and packaging industries. Bagging is a crucial step in the production and packaging of modified plastic granules; however, traditional bagging equipment suffers from numerous problems in practical applications and struggles to meet the demands of modern production.

[0003] (1) Traditional bagging devices mostly use gravity feeding, relying on the material's own weight to flow into the packaging bag through the feeding port. This method has the problem of uncontrollable feeding speed. Gravity feeding is difficult to precisely adjust the feeding speed, which can easily lead to inconsistent bag weight, large errors, and affect product quality.

[0004] (2) During the feeding process, the modified plastic particles have poor flowability due to differences in particle size, shape and surface characteristics. Traditional devices are prone to bridging and arching, resulting in poor feeding or even complete blockage, which affects the bagging efficiency.

[0005] (3) Traditional bagging devices usually adopt a gate-type interception structure, which controls the opening and closing of the discharge port through a mechanical gate. This method has the problem of delayed dripping: after the gate is closed, due to the inertia and gravity of the material, a small amount of material will still drip from the gap, which can easily cause waste of raw materials. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by providing a modified plastic granule bagging device to solve the problems mentioned in the background art.

[0007] To achieve this objective, the present invention adopts the following technical solution:

[0008] A modified plastic granule bagging device includes a storage bin with three equidistant feeding hoppers installed on the bottom outer wall of the storage bin. A circular discharge cover is installed at one end of the bottom of each feeding hopper. A motor is installed on one outer wall of the circular discharge cover. The output shaft of the motor is fixedly connected to a rotating rod via a coupling. Six equidistant distributing plates are fixedly connected to the outer wall of the rotating rod. The outer wall of the distributing plates is clearance-fitted with the inner wall of the circular discharge cover, and the clearance between the distributing plates and the inner wall of the circular discharge cover is less than the minimum particle radius.

[0009] As a preferred embodiment of the modified plastic granule bagging device, the top of the circular discharge hood is connected to the bottom of the discharge hopper through an opening, and a square discharge pipe is installed on the bottom outer wall of the circular discharge hood through an opening.

[0010] As a preferred embodiment of the modified plastic granule bagging device, a motor fixing cover is fixedly provided on one outer wall of the circular discharge hood, and the motor is fixed to the inner wall of the motor fixing cover.

[0011] As a preferred embodiment of the modified plastic granule bagging device, the top outer wall of the storage box is fixedly provided with a positioning plate by a bracket, and the bottom outer wall of the positioning plate is fixedly provided with three vertically downward positioning sleeves that are evenly distributed. The inner wall of the positioning sleeves is fixedly provided with vertically downward vibration springs, and the bottom end of the three vibration springs is fixedly provided with a vertically downward vibration sleeve. The bottom end of the three vibration sleeves is located at the connection between the hopper and the circular discharge hood.

[0012] As a preferred embodiment of the modified plastic granule bagging device, a vibration motor is fixedly installed on the inner wall of the three vibration sleeves.

[0013] As a preferred embodiment of the modified plastic granule bagging device, two bag inserts are fixedly provided on one side of the bottom of the circular discharge hood by a bracket, and the two bag inserts are respectively located on both sides of the square discharge pipe.

[0014] As a preferred embodiment of the modified plastic granule bagging device, two downwardly curved support plates are fixedly provided on one side of the outer wall of the storage box, and a fixing plate is fixedly provided at the bottom end of the two support plates. The outer wall of the fixing plate has a fixing hole, and the inner wall of the fixing hole is equipped with a matching bolt.

[0015] The beneficial effects of this utility model are:

[0016] (1) By adjusting the speed of the motor, the present invention can realize the linear speed regulation of the material distribution plate. The feeding speed can be precisely adjusted according to the bagging capacity requirements, which is significantly better than the traditional gravity feeding device. The six equally distributed material distribution plates are fitted with the inner wall of the circular discharge hood, so that the material is evenly cut and pushed, avoiding local accumulation or cavity phenomenon. It is especially suitable for modified plastic granules with poor flowability.

[0017] (2) This utility model achieves physical material cutting off quickly by forming a closed ring surface between the six material distribution plates and the inner wall of the discharge hood after the motor is powered off, thereby avoiding the delayed dripping problem of traditional gate-type interception devices.

Detailed Implementation

[0025] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0026] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent. To better illustrate the embodiments of this utility model, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0027] In the accompanying drawings of this utility model, the same or similar reference numerals correspond to the same or similar components. In the description of this utility model, it should be understood that if terms such as "upper," "lower," "left," "right," "inner," and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0028] In the description of this utility model, unless otherwise explicitly specified and limited, the term "connection" or similar designation indicating the connection relationship between components should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral part; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] like Figures 1 to 4 As shown, this utility model provides a modified plastic granule bagging device, including a storage box 1, a feeding hopper 2, a circular discharge cover 3, a square feeding pipe 4, a motor 6, a rotating rod 7, a material distribution plate 8, a bag insertion rod 9, a positioning plate 10, a positioning sleeve 11, a vibration spring 12, a vibration sleeve 13, a vibration motor 14, a support plate 15, a fixing plate 16, and a fixing hole 17.

[0030] The storage bin 1 has three equidistantly distributed feeding hoppers 2 at its bottom. Each feeding hopper 2 is connected to a circular discharge cover 3 at its bottom. The top of the circular discharge cover 3 is connected to the feeding hopper 2 through an opening, and the bottom discharges material through a square feeding pipe 4. The motor 6 drives six equidistantly distributed distribution plates 8 to rotate via a rotating rod 7. The distribution plates 8 are fitted with the inner wall of the circular discharge cover 3 with a clearance, and the gap between the distribution plates 8 and the circular discharge cover 3 is smaller than the minimum particle radius, so the material can be discharged evenly. The speed of the motor 6 is adjustable, and the feeding speed is controlled by adjusting the speed. The higher the speed, the faster the feeding; the lower the speed, the slower the feeding. The positioning sleeve 11 at the top of the storage bin 1 is connected to the vibrating sleeve 13 by a vertically oriented vibrating spring 12. The vibrating motor 14 is built into the vibrating sleeve 13. After starting, the vibrating motor 14 generates high-frequency micro-amplitude vibration, which is transmitted through the vibrating sleeve 13 to the connection between the feeding hopper 2 and the circular discharge cover 3 to avoid material accumulation or bridging.

[0031] When the motor 6 is turned off, the material distribution plate 8 immediately stops rotating. The material distribution plate 8 and the inner wall of the circular discharge hood 3 form a closed blocking surface, cutting off the material flow path and achieving instantaneous material cut-off. The equidistant distribution of 6 material distribution plates 8 ensures that the material discharge channel can be completely closed at any stopping position, preventing residual material from dripping. When the motor 6 is turned off, the vibration motor 14 is turned off simultaneously, so that the material is no longer discharged. The material bag insertion rod 9 is located on both sides of the square discharge pipe 4 and is used to fix the material bag. After the material discharge stops, the material bag is removed.

[0032] Preferably, in this embodiment, the storage bin 1 is provided with two downwardly curved support plates 15 on one side, and the bottom of the support plates 15 is connected to a fixing plate 16. The fixing plate 16 has fixing holes 17, and the device is fixed to the workbench by bolts.

[0033] Working principle and usage process of this utility model:

[0034] When using this modified plastic granule bagging device, first, the modified plastic granules to be bagged are put into the storage bin 1, the bag is placed on the square feed pipe 4 and fixed with the bag insertion rod 9, the motor 6 and the vibration motor 14 are turned on, and the speed of the motor 6 is adjusted to the required feeding speed. The modified plastic granules fall from the storage bin 1 into the feed hopper 2, and the plastic granules in the feed hopper 2 fall into the circular discharge hood 3. The output shaft of the motor 6 drives the rotating rod 7 and the distribution plate 8 to rotate, and the modified plastic granules fall from the square feed pipe 4 into the bag. After the bag is filled with the specified mass of modified plastic granules, the motor 6 and the vibration motor 14 are turned off.

[0035] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles employed. Those skilled in the art should understand that various modifications, equivalent substitutions, and variations can be made to this utility model. However, such variations, as long as they do not depart from the spirit of this utility model, should be within the protection scope of this utility model. Furthermore, some terminology used in this application specification and claims is not limiting, but merely for ease of description.
