Abstract
Description
Technical Field
[0001] This utility model relates to a cooling device, and more particularly to a cooling device for the production of cold-resistant PVC waterproof rolls. Background Technology
[0002] In the production process of cold-resistant PVC waterproof membrane, the cooling process plays a decisive role in the physical properties and durability of the product. Cold-resistant PVC waterproof membrane is often used in building waterproofing projects in cold regions and needs to have good flexibility, tensile strength and low temperature resistance. Reasonable cooling treatment is the key to ensuring that these properties meet the standards.
[0003] Traditional cooling devices used in the production of cold-resistant PVC waterproof membranes have many problems in practical applications. In air-cooled equipment, the layout of the cooling fans is unreasonable, which makes it impossible for the blown cold air to cover the surface of the waterproof membrane evenly. This results in inconsistent cooling rates in different parts of the PVC waterproof membrane, which can easily cause uneven internal stress in the product and affect the product's flexibility, tensile strength and other physical properties. Utility Model Content
[0004] To overcome the drawback of inconsistent cooling speeds in different parts of the PVC waterproof roll due to an unreasonable layout of the cooling fan, this utility model provides a cooling device for the production of cold-resistant PVC waterproof rolls.
[0005] The technical solution is as follows: A cooling device for the production of cold-resistant PVC waterproof rolls includes an air-cooled box, a power box, a motor, a transmission rod, a first bevel gear, a second bevel gear, a rotating shaft, a support plate, and a cooling fan. The power box is located on one side of the air-cooled box, and the motor is located at the bottom of the power box. A transmission rod is connected to the output shaft of the motor, and the first bevel gear is located on the transmission rod. The support plate is located inside the power box and is rotatably connected to the air-cooled box. A transmission shaft is located at the end of the support plate facing the power box, and the rotating shaft is rotatably connected to both the air-cooled box and the power box. A second bevel gear is located on the rotating shaft, and the first bevel gear meshes with the second bevel gear. A cooling fan is located on the support plate.
[0006] Optionally, the support plate is provided in two parts, upper and lower, in the air-cooled box.
[0007] Optionally, it also includes a water-cooled box and a limiting shaft, with a water-cooled box at one end of the air-cooled box, and a limiting shaft rotatably installed inside the water-cooled box.
[0008] Optionally, it also includes a coolant tank, a delivery pipe, a water outlet pipe, a water pump, a first connecting pipe, and a nozzle.

Detailed Implementation
[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.
[0019] A cooling device for the production of cold-resistant PVC waterproof rolls, such as Figures 1-4 As shown, the device includes an air-cooled box 2, a power box 3, a motor 14, a transmission rod 15, a first bevel gear 16, a second bevel gear 17, a rotating shaft 18, a support plate 19, and cooling fans 20. The power box 3 is located on the right side of the air-cooled box 2, and the motor 14 is located at the bottom of the power box 3. The transmission rod 15 is connected to the output shaft of the motor 14, and the first bevel gear 16 is mounted on the transmission rod 15. The support plate 19 is located inside the power box 3 and is rotatably connected to the air-cooled box 2. A transmission shaft is located at one end of the support plate 19 facing the power box 3. The rotating shaft 18 is rotatably connected to both the air-cooled box 2 and the power box 3. The second bevel gear 17 is mounted on the rotating shaft 18, and the first bevel gear 16 meshes with the second bevel gear 17. Multiple cooling fans 20 are evenly arranged on the support plate 19.
[0020] When using this device to cool the PVC waterproof roll, the PVC waterproof roll will enter the air-cooling box 2 through the traction mechanism. When the PVC waterproof roll enters the air-cooling box 2, the cooling fan 20 on the support plate 19 will start to cool the PVC waterproof roll. At the same time, the motor 14 in the power box 3 will start. The motor 14 will reciprocate within a range of ±50 degrees through its output shaft. The rotation of the output shaft of the motor 14 will drive the transmission rod 15 to reciprocate. The rotation of the transmission rod 15 will drive the first bevel gear 16 to rotate. The rotation of the first bevel gear 16 will drive the second bevel gear 17 meshing with it to rotate. The rotation of the second bevel gear 17 will drive the support plate 19 to swing back and forth within a certain angle range through the rotating shaft 18. The cooling fan 20 installed on the support plate 19 will swing accordingly to cool the PVC waterproof roll over a wider range.
[0021] like Figure 4 As shown, the support plate 19 is provided in the air-cooled box 2 in two parts, upper and lower. Multiple cooling fans 20 are provided on the sides of the upper and lower support plates 19 facing each other. The PVC waterproof roll is provided with support plates 19 on both the upper and lower sides. The cooling fans 20 on the upper and lower support plates 19 provide air cooling to the upper and lower surfaces of the PVC waterproof roll, improving the air cooling efficiency.
[0022] like Figure 2As shown, it also includes a water-cooled box 1 and limiting shafts 7. The air-cooled box 2 is provided at one end with the water-cooled box 1. Two limiting shafts 7 are rotatably arranged in the center of the interior of the water-cooled box 1. Before air cooling, the PVC waterproof roll is first pulled into the water-cooled box 1 by the traction mechanism. Under the constraint of the limiting shafts 7, the PVC waterproof roll will slide below the limiting shafts 7, allowing the PVC waterproof roll to be completely immersed in water. Since there are two limiting shafts 7, when the PVC waterproof roll slides below the two limiting shafts 7, the movement path is increased, and the contact area between the PVC waterproof roll and the water is expanded, so that the PVC waterproof roll can be water-cooled in the water-cooled box 1. Then, it is transported to the air-cooled box 2 by the traction mechanism. The heat dissipation efficiency is improved through multi-stage heat dissipation and increased contact area.
[0023] like Figure 1 and Figure 3 As shown, the system also includes a coolant tank 4, a delivery pipe 8, a water outlet pipe 9, a water pump 10, a first connecting pipe 11, and nozzles 13. The coolant tank 4 is located at the left end of the water-cooled box 1, and the water pump 10 is located on one side of the coolant tank 4. The inlet of the water pump 10 is connected to the coolant tank 4 through the first connecting pipe 11, and the outlet of the water pump 10 is connected to the water outlet pipe 9. The water outlet pipe 9 is connected to the delivery pipe 8, which is located inside the water-cooled box 1. Multiple nozzles 13 are evenly arranged on the delivery pipe 8. During water cooling in the water-cooled box 1, the water pump 10 pumps the cooled water from the coolant tank 4 through the first connecting pipe 11, pumps it through the water outlet pipe 9 to the delivery pipe 8, and then sprays it onto the PVC waterproof roll through the nozzles 13 on the delivery pipe 8. The sprayed water has a certain flow rate, and the flowing water carries away the heat from the PVC waterproof roll, improving the water cooling efficiency.
[0024] like Figure 1 and Figure 3 As shown, it also includes a second connecting pipe 12. Multiple second connecting pipes 12 are provided on the upper part of the coolant tank 4, and the coolant tank 4 is connected to the water-cooled tank 1 through the second connecting pipes 12. In the water-cooled tank 1, the water sprayed from the nozzle 13 causes the water level to rise. When the water level rises to the same height as the opening of the second connecting pipe 12, the water can enter the coolant tank 4 through the second connecting pipe 12. The coolant tank 4 cools the incoming water, and then the water is pumped to the water-cooled tank 1 by the water pump 10, maintaining a stable water temperature in the water-cooled tank 1 and improving heat dissipation efficiency.
[0025] like Figure 1 and Figure 4As shown, it also includes a first protective wheel 5, a second protective wheel 6, and a third protective wheel 21. The first protective wheel 5 and the second protective wheel 6 are rotatably arranged at the left and right ends of the water-cooled box 1, respectively, and the third protective wheel 21 is rotatably arranged at the discharge port of the air-cooled box 2. When the traction mechanism pulls the PVC waterproof roll, the first protective wheel 5 and the second protective wheel 6 prevent the PVC waterproof roll from rubbing against the box body in the water-cooled box 1; the second protective wheel 6 and the third protective wheel 21 prevent the PVC waterproof roll from rubbing against the box body in the air-cooled box 2, thereby reducing damage to the PVC waterproof roll.
[0026] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
