Abstract
Description
Technical Field
[0001] This utility model relates to the field of cooling device technology, specifically a cooling device for the production of modified polyethylene masterbatch. Background Technology
[0002] Polyethylene masterbatch is a masterbatch made primarily from polyethylene, a polymer formed by polymerizing ethylene monomers. Polyethylene is the simplest polymer in terms of structure and is also the most widely used polymer material. In the production process of modified polyethylene masterbatch, the material in a high-temperature molten state needs to be cooled and shaped before it can enter the subsequent processing stage.
[0003] However, when cooling the masterbatch, the unleveled masterbatch tends to clump together on the conveyor belt, reducing cooling efficiency. Therefore, a cooling device for the production of modified polyethylene masterbatch is proposed to overcome the above problems. Utility Model Content
[0004] The purpose of this invention is to provide a cooling device for the production of modified polyethylene masterbatch. The flat plate driven by the rotating shaft dynamically disperses the sticky masterbatch through the comb teeth, so that it is evenly spread on the conveyor belt, increasing the heat dissipation surface area and avoiding local overheating or insufficient cooling. This solves the problem that unflattened masterbatch easily sticks together on the conveyor belt, reducing cooling efficiency.
[0005] This utility model is achieved through the following technical solution:
[0006] This utility model is a cooling device for the production of modified polyethylene masterbatch, including a cooling box and a leveling mechanism. The leveling mechanism includes a rotating shaft, which is set inside the cooling box. The two ends of the rotating shaft are respectively fitted onto the inner side walls of the cooling box. Eight leveling plates are evenly distributed on the outside of the rotating shaft. One side of the leveling plate is evenly distributed with comb teeth. A mounting plate is provided on the front side of the cooling box. A driving component is provided on the mounting plate. The output end of the driving component is connected to one end of the rotating shaft.
[0007] Furthermore, the cooling box is equipped with a conveyor belt inside, and a leveling mechanism is located above the conveyor belt.
[0008] Furthermore, a fan is provided at one end of the cooling box, and conveying pipes are connected to both sides of the fan. Air outlets are evenly distributed on the opposite sides of the two conveying pipes, and one end of the air outlet is located inside the cooling box.
[0009] Furthermore, the air outlet tilt is set on the delivery pipe.
[0010] Furthermore, a feed hopper is provided at the top of the cooling box, and a guide plate is provided at the other end of the cooling box, with the guide plate located below one side of the conveyor belt.
[0011] This utility model has the following beneficial effects:
[0012] 1. This utility model uses a rotating shaft-driven flat plate to dynamically break up the sticky masterbatch through comb teeth, so that it is evenly spread on the conveyor belt, increasing the heat dissipation surface area, avoiding local overheating or insufficient cooling, and solving the problem that unleveled masterbatch easily sticks together on the conveyor belt, reducing cooling efficiency.
[0013] 2. This utility model uses an air outlet to spray air at an inclined angle, forming cross-convection that covers the transverse and longitudinal spaces of the conveyor belt, reducing cooling dead zones and improving heat exchange efficiency by approximately [percentage missing].
[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[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] Please see Figure 1-4This utility model provides a technical solution: a cooling device for the production of modified polyethylene masterbatch, including a cooling box 1 and a leveling mechanism 5. The leveling mechanism 5 includes a rotating shaft 501, which is disposed inside the cooling box 1. The two ends of the rotating shaft 501 are respectively fitted to the inner side walls of the cooling box 1. Eight leveling plates 502 are evenly distributed on the outside of the rotating shaft 501. One side of the leveling plate 502 is evenly distributed with comb teeth 503. The rotation of the rotating shaft 501 drives the leveling plate 502 to move. The comb teeth 503 break up the sticky masterbatch, avoids the accumulation of clumps, ensures uniform distribution of a single layer, exposes more surface area of the leveled masterbatch layer, accelerates heat dissipation, and improves cooling efficiency by about 25%. The continuous combing action reduces the risk of material jamming and is suitable for high viscosity modified polyethylene. The front side of the cooling box 1 is provided with a mounting plate, and the mounting plate is provided with a driving component 7. The driving component 7 drives the rotating shaft 501 to rotate. The leveling speed can be adjusted to adapt to different production requirements. The output end of the driving component 7 is connected to one end of the rotating shaft 501.
[0022] Driven by the rotating shaft 501, the flat plate 502 dynamically disperses the sticky masterbatch through the comb teeth 503, so that it is evenly spread on the conveyor belt 6, increasing the heat dissipation surface area and avoiding local overheating or insufficient cooling. This solves the problem that unflattened masterbatch easily sticks together on the conveyor belt 6, reducing cooling efficiency.
[0023] The cooling box 1 is equipped with a conveyor belt 6, which carries and transports the masterbatch and works in conjunction with the leveling mechanism 5, which is located above the conveyor belt 6.
[0024] A fan 2 is installed at one end of the cooling box 1. Conveying pipes 3 are connected to both sides of the fan 2. Air outlets 4 are evenly distributed on the opposite sides of the two conveying pipes 3. The fan 2 provides forced cooling air, which is distributed to the air outlets 4 through the conveying pipes 3. The air outlets 4 are inclined at 30 degrees on the conveying pipes 3, with one end located inside the cooling box 1. This 30° inclined design of the air outlets 4 creates a cross-flow field, covering the entire width of the conveyor belt 6. The airflow is sprayed obliquely from both sides, avoiding localized overcooling / overheating caused by direct blowing and eliminating cooling dead zones. The airflow is concentrated on the material layer, reducing ineffective losses and lowering energy consumption by 15%–20%.
[0025] Airflow is sprayed at an angle through the air outlet 4, forming cross convection, covering the horizontal and vertical space of the conveyor belt 6, reducing cooling dead zones, and improving heat exchange efficiency by about 20%.
[0026] The top of the cooling box 1 is equipped with a feeding hopper 101, which enables continuous feeding and reduces manual intervention. The other end of the cooling box 1 is equipped with a guide plate 102. The inclination angle of the guide plate 102 is usually (45-60°) to ensure that the material is discharged smoothly and reduce damage. The guide plate 102 is located below one side of the conveyor belt 6. The guide plate 102 guides the cooled masterbatch to slide to the next process.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
