Description

Technical Field

[0001] This utility model relates to the field of EPS foam production technology, specifically to a cooling device for EPS foam products. Background Technology

[0002] EPS foam undergoes a foaming and expansion process at high temperatures, forming a porous foam structure. After foaming is complete, timely cooling helps stabilize the foam structure, preventing it from continuing to expand or deform, thus maintaining the required shape and size. The cooling process also helps the EPS foam to cure, giving it better physical properties such as strength, hardness, and durability.

[0003] A search revealed CN222271026U, which discloses a cooling mechanism for EPS foam product production, belonging to the field of EPS foam cooling technology. The mechanism includes a frame with a conveyor belt in the middle, auxiliary mechanisms between the frames, a drive assembly at one end, and a support assembly at the bottom. Support springs provide cushioning to prevent rigid impacts. Side guards are mounted on the frame, and clamping plates on both sides, driven by clamping shafts, clamp the foam boards to prevent them from shaking. The height of the first and second support rods at the bottom can be determined by bolts for easier operation. A top blowing plate and a bottom blowing device body can cool the foam boards on the conveyor belt. The height of the upper conveyor belt and the distance between the upper blowing plate and the foam boards can be adjusted by a lifting motor.

[0004] However, in actual use, the cooling effect of the entire cooling mechanism is generally poor, and the overall energy consumption of the mechanism is relatively high, so it needs to be improved. Utility Model Content

[0022] 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.

[0023] Please see Figure 1-4This utility model provides a technical solution: a cooling device for EPS foam products, including a cooling box 1. Two cooling rollers 2 are rotatably connected inside the cooling box 1. A cooling cavity 3 is formed inside each cooling roller 2. A conveyor belt 4 is fitted onto the outer surface of both cooling rollers 2. Multiple cooling columns 5 are equidistantly arranged on the surface of the conveyor belt 4, with the ends of the cooling columns 5 penetrating the conveyor belt 4 and flush with its inner surface. A first refrigeration mechanism 6 is fixedly installed on one side of the outer surface of the cooling box 1 to deliver cold air into the cooling cavity 3. An exhaust port 7 communicating with the cooling cavity 3 is formed at the rotating end of each cooling roller 2. A second refrigeration mechanism 8 is fixedly installed on the other side of the outer surface of the cooling box 1 to deliver cold air into the cooling box 1. Two opposing cooling mechanisms are formed on the surface of the cooling box 1. The input end of the conveyor belt 4 and the window 9 facing the output end of the conveyor belt 4 are equipped with a cooling box 1, a cooling roller 2, a conveyor belt 4, a cooling column 5, a first refrigeration mechanism 6, and a second refrigeration mechanism 8. The first refrigeration mechanism 6 delivers cold air into the cooling chamber 3, thereby cooling the cooling roller 2. By cooling the cooling roller 2, the cooling column 5 is cooled, thus achieving a first cooling effect on the foam product. The second refrigeration mechanism 8 delivers cold air into the cooling box 1, thereby cooling the internal space of the cooling box 1, thus achieving a second cooling effect on the foam product. When the conveyor belt 4 moves and carries the foam product through the cooling box 1, the double cooling effectively improves the cooling effect of the foam product and increases work efficiency.

[0024] The first refrigeration mechanism 6 includes a first air cooler 10, a three-way pipe 11, and a tripod 12. The tripod 12 is fixedly connected to the side of the cooling box 1, and the first air cooler 10 is fixedly connected to the tripod 12. One end of the three-way pipe 11 is fixedly connected to the output end of the first air cooler 10, and the other two ends of the three-way pipe 11 extend into the two cooling chambers 3 respectively. The cooling rollers 2 are rotatably connected to the three-way pipe 11. When the first air cooler 10 is working, cold air can be input from the three-way pipe 11 into the cooling chambers 3 of the two cooling rollers 2. By setting an exhaust port 7, the gas after heat exchange can be discharged.

[0025] The second refrigeration mechanism 8 includes a second air cooler 13 and an air supply pipe 14. The second air cooler 13 is fixedly connected to the surface of the cooling box 1. One end of the air supply pipe 14 is fixedly connected to the output end of the second air cooler 13, and the other end of the air supply pipe 14 extends into the interior of the cooling box 1. By operating the second air cooler 13, the air supply pipe 14 can deliver cold air into the cooling box 1, thereby cooling the interior of the cooling box 1.

[0026] Multiple heat dissipation copper strips 15 are fixedly connected at equal intervals on the surface of the conveyor belt 4, and the cooling columns 5 in the same row are all fixedly connected to the same heat dissipation copper strip 15. By setting the heat dissipation copper strips 15, the heat absorbed by the cooling columns 5 can be easily dissipated.

[0027] Multiple fan blades 16 are fixedly connected in a ring array on the outer surface of the rotating end of the cooling roller 2, and the output end of the air supply pipe 14 corresponds to the fan blades 16. By setting the fan blades 16, the second cold air blower 13 works and blows air to the fan blades 16 through the air supply pipe 14, which can drive the rotation of the cooling roller 2, thereby driving the conveyor belt 4 to rotate. This equipment does not require a motor to drive the cooling roller 2 to rotate. Compared with the existing technology, it effectively reduces energy consumption and is more energy-saving and environmentally friendly.

[0028] Multiple staggered baffles 17 are fixedly connected to the inner wall of the cooling chamber 3. By setting the baffles 17, the residence time of cold air in the cooling chamber 3 can be increased, which is beneficial for the cooling roller 2 to cool down.

[0029] Guide rollers 18 are rotatably connected to the inner wall of window 9. By setting guide rollers 18 and utilizing their rotation, the foam products can be effectively prevented from making hard contact with the inner wall of window 9.

[0030] Working principle: When this EPS foam product cooling equipment is in use, the foam product is first introduced into the cooling box 1 through window 9 and placed on the surface of the cooling column 5. In practical applications, a conveyor belt can be used to introduce the foam product. The first cold air fan 10 works, and cold air can be delivered into the cooling chamber 3 through the three-way pipe 11, thereby cooling the cooling roller 2. By cooling the cooling roller 2, the cooling column 5 can be cooled, thus achieving the first cooling of the foam product. The second cold air fan 13 works, and cold air enters the cooling box 1 through the air supply pipe 14, thereby cooling the internal space of the cooling box 1, thus achieving the second cooling of the foam product. As the conveyor belt 4 rotates, the foam product will be discharged from the window 9 at the other end. Through double cooling, the cooling effect of the foam product is effectively improved, and the work efficiency is improved.
