Description

Technical Field

[0001] This utility model relates to the field of polyethylene foam production facilities, and in particular to a cooling device for polyethylene foam production. Background Technology

[0002] Polyethylene foam is a non-crosslinked closed-cell material made from low-density polyethylene resin through physical foaming. It contains evenly distributed independent air bubbles and possesses shockproof, waterproof, soundproof, and thermal insulation properties. Its functionality is enhanced by adding antistatic agents and flame retardants. When combined with fabrics and aluminum foil, it can further improve mechanical strength and UV protection, overcoming the fragility and deformation defects of traditional foams. Due to its lightweight, softness, and corrosion resistance, polyethylene foam is widely used in cushioning and protection applications such as electronics, medical devices, craft packaging, and automotive interiors. Customized designs in liquor packaging also reduce transportation damage rates. The production process of polyethylene foam includes foaming, slitting, heat bonding, and cooling. Because of its special advantages—it does not pollute the environment and can be repeatedly recycled—polyethylene foam will find wider applications in packaging and filling materials as time progresses and products are continuously developed and applied. During the production process, to quickly set the polyethylene foam, it needs to be cooled using polyethylene foam cooling equipment.

[0003] Currently, polyethylene foam cooling equipment requires manual placement of polyethylene foam to the desired cooling position and manual removal of the cooled polyethylene foam during the cooling process. This results in low cooling efficiency for polyethylene foam, affecting the production efficiency of polyethylene foam. Therefore, a cooling device for polyethylene foam production is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a cooling device for polyethylene foam production, aiming to improve the problem that the existing polyethylene foam cooling equipment requires manual placement of polyethylene foam to the required cooling position and manual removal of cooled polyethylene foam during the cooling process, resulting in low cooling efficiency of polyethylene foam and affecting the production efficiency of polyethylene foam.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a cooling device for polyethylene foam production, comprising a cooling box and a cold air blower. The cold air blower is mounted on the outer top wall of the cooling box via a top bracket. The air outlet of the cold air blower is connected to a vertical pipe. The bottom end of the pipe extends into the interior of the cooling box and is connected to an air distribution box. Rectangular shift holes are provided on both sides of the bottom of the cooling box. A horizontal mesh plate is fixed on the inner side wall of the bottom of the cooling box. A horizontal conveyor belt is mounted on one side of the outer side wall of the cooling box via a side bracket. A side plate is fixed on the rear side of the other side of the cooling box. A horizontal winding column is rotatably connected to the side of the side plate away from the cooling box via a bearing. A winding motor is mounted on the rear side wall of the side plate via a motor frame. The rear end of the winding column is fixed to the output end of the winding motor.

[0006] As a further description of the above technical solution: The air distribution box is fixed to the inner wall of the cooling box, and multiple evenly distributed air distribution pipes are connected to the bottom wall of the air distribution box. The air distribution pipes are located above the displacement hole.

[0007] As a further description of the above technical solution: The top of the conveyor belt of the conveyor is flush with the inner bottom wall of the shifting hole, the size of the mesh plate is adapted to the inner bottom wall of the cooling box, and the top wall of the mesh plate is flush with the inner bottom wall of the shifting hole.

[0008] As a further description of the above technical solution: A paper tube is movably fitted around the outer ring of the roller located on the front side of the side plate, and the top of the paper tube is located below the shift hole.

[0009] As a further description of the above technical solution: The inner ring of the paper tube is adapted to the outer ring of the roll, and the outer ring surface of the roll is provided with anti-slip texture.

[0010] As a further description of the above technical solution: The four corners of the outer bottom wall of the cooling box are all fixed with supports.

[0011] As a further description of the above technical solution: The bottom wall of the cooling box has multiple evenly distributed heat dissipation holes.

[0012] This utility model has the following beneficial effects: In this invention, during the cooling process, polyethylene foam is placed at the top of the conveyor belt of a conveyor belt. The operation of the conveyor belt causes the polyethylene foam to be located on the top wall of the mesh plate. The operation of the cooling fan causes multiple evenly distributed air distribution pipes to evenly blow cold air onto the polyethylene foam on the top wall of the mesh plate, so that the heat of the polyethylene foam can be quickly dissipated through the mesh and heat dissipation holes of the mesh plate. Through the operation of the conveyor belt and the winding motor, the cooled polyethylene foam can be automatically wound up by the paper tube.

[0013] This invention can automatically move the polyethylene foam to the required cooling position during the cooling process, allowing the heat of the polyethylene foam to dissipate quickly. It can also automatically rewind the cooled polyethylene foam, effectively improving the cooling efficiency of polyethylene foam and thus its production efficiency. Attached Figure Description

[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] Reference Figures 1-4This utility model provides an embodiment of a cooling device for polyethylene foam production, including a cooling box 1 and a cooler 4. Supports 10 are fixed at the four corners of the outer bottom wall of the cooling box 1, providing stable support on the ground and enhancing its stability. The cooler 4 is mounted on the outer top wall of the cooling box 1 via a top bracket. A vertical pipe 3 is connected to the air outlet of the cooler 4. The bottom end of the pipe 3 extends into the interior of the cooling box 1 and is connected to a distribution box 12. Rectangular sliding holes 5 are provided on both sides of the bottom of the cooling box 1. A horizontal mesh plate 11 is fixed on the inner side wall of the bottom of the cooling box 1. Multiple evenly distributed heat dissipation holes 14 are provided on the bottom wall of the cooling box 1, allowing the heat from the polyethylene foam on the top wall of the mesh plate 11 to dissipate through the mesh and heat dissipation holes 14. A horizontal conveyor belt 2 is installed on one side of the outer wall of the cooling box 1 via a side bracket. A side plate 6 is fixed to the rear side of the other side of the outer wall of the cooling box 1. A horizontal roller 8 is rotatably connected to the side of the side plate 6 away from the cooling box 1 via a bearing. A winding motor 7 is installed on the rear side wall of the side plate 6 via a motor frame. The rear end of the roller 8 is fixed to the output end of the winding motor 7.

[0018] Reference Figures 2-3 The air distribution box 12 is fixed on the inner wall of the cooling box 1. Multiple evenly distributed air distribution pipes 13 are connected to the bottom wall of the air distribution box 12. The air distribution pipes 13 are located above the shift hole 5 and can evenly discharge air to the polyethylene foam on the top wall of the mesh plate 11 through the multiple evenly distributed air distribution pipes 13.

[0019] Reference Figures 1-3 The top of the conveyor belt of the conveyor belt 2 is flush with the inner bottom wall of the shifting hole 5. The size of the mesh plate 11 is adapted to the inner bottom wall of the cooling box 1. The top wall of the mesh plate 11 is flush with the inner bottom wall of the shifting hole 5. The polyethylene foam is moved to the right by the conveyor belt of the conveyor belt 2, and the polyethylene foam can be moved to the top wall of the mesh plate 11 through the shifting hole 5 on the left.

[0020] Reference Figures 1-3 A paper tube 9 is movably fitted on the outer ring of the scroll 8 located on the front side of the side plate 6. The top of the paper tube 9 is located below the shift hole 5. The cooled polyethylene foam can be wound up through the paper tube 9. The inner ring of the paper tube 9 is adapted to the outer ring of the scroll 8, making it easy to remove the paper tube 9 after winding up the polyethylene foam. The outer ring surface of the scroll 8 is provided with anti-slip texture, which makes the friction between the outer ring of the scroll 8 and the inner ring of the paper tube 9 greater, which can prevent the paper tube 9 from accidentally detaching from the scroll 8, so that the paper tube 9 can rotate with the scroll 8.

[0021] Working principle: To cool polyethylene foam, place it at the top of the conveyor belt of conveyor 2. The conveyor belt moves the polyethylene foam to the right until it passes through the left-side sliding hole 5 and enters the cooling box 1. The polyethylene foam then rests on the top wall of the mesh plate 11, which supports it. The mesh plate 11 automatically moves the polyethylene foam to the desired cooling position. The cool air blower 4 delivers cool air through the pipe 3 to the air distribution box 12, allowing multiple evenly distributed air distribution pipes 13 to uniformly distribute cool air onto the polyethylene foam on the top wall of the mesh plate 11, thus cooling the foam. The heat from the polyethylene foam on the top wall of the screen plate 11 is quickly dissipated through the mesh and heat dissipation holes 14, allowing the polyethylene foam on the top wall of the screen plate 11 to cool down rapidly. Continuing to operate via the conveyor belt 2, the cooled polyethylene foam is moved through the right-side shifting hole 5 to the top of the paper tube 9. The polyethylene foam is pressed onto the top of the paper tube 9. The winding motor 7 drives the winding column 8 and the paper tube 9 to rotate, automatically winding up the cooled polyethylene foam through the paper tube 9. During the cooling process, the polyethylene foam can be automatically moved to the required cooling position and automatically wound up, effectively improving the cooling efficiency of the polyethylene foam and thus its production efficiency.
