Description
Technical Field
[0001] This utility model relates to the field of laminating machines, specifically a roller cooling device for a pad laminating machine. Background Technology
[0002] The laminating machine is used for gluing and laminating pads. After gluing and lamination, the pads are discharged through multiple rollers. Because the glue needs to be heated during the gluing process to ensure its bonding effect, the temperature of the rollers in contact with the pads is usually quite high. When glue adheres to the rollers, it melts on the side walls of the rollers, causing the melted glue to stick to the rollers. This interferes with the discharge of the pads, affecting their smoothness. Pads stuck to the rollers may bend and be damaged, affecting the quality of the pads after lamination. Therefore, air-cooling fans are usually installed at the discharge rollers to cool them down. However, due to the large size of the rollers and their usual metal material, simply using air-cooling fans for cooling is not very effective. Glue residue may still remain, causing the pads to stick to the rollers, affecting the smoothness and quality of the pad lamination process. Utility Model Content
[0003] The purpose of this utility model is to provide a roller cooling device for a pad composite machine. It can solve the technical problem that the existing air-cooled fan has a poor cooling effect on the roller. It increases the cooling area of the air-cooled roller and combines air-cooling and water-cooling methods to further improve the cooling effect on larger rollers, ensuring the smoothness and quality of pad composite processing.
[0004] To achieve the above objectives, this utility model employs the following technical solution:
[0005] A roller cooling device for a pad laminating machine includes a rotating shaft rotatably connected to the machine body, a roller shaft on the outside of the rotating shaft, an air inlet and an air outlet at both ends of the rotating shaft, an air inlet pipe and an air outlet pipe rotatably connected to the air inlet and air outlet respectively, multiple air-cooling channels inside the roller shaft, multiple lower air ducts connected to both the air inlet and air outlet, upper air ducts connected to both ends of the air-cooling channels, the lower air ducts and upper air ducts connected, a liquid cooling box below the roller shaft, an inlet pipe and an outlet pipe on the liquid cooling box, an outlet pipe extending into the liquid cooling box, multiple air-cooling pipes below the roller shaft, multiple air nozzles on the air-cooling pipes facing the roller shaft, and the end of the outlet pipe penetrating the liquid cooling box and simultaneously connected to the multiple air-cooling pipes.
[0006] Furthermore, the machine body is symmetrically provided with upright plates, and the two ends of the rotating shaft are respectively rotatably connected to the upright plates on both sides.
[0007] Furthermore, the uprights on both sides are respectively provided with rotary joints that communicate with the air inlet pipe and the air outlet pipe, and the two ends of the rotating shaft are respectively connected to the rotary joints on both sides.
[0008] Furthermore, the air-cooling channels extend along the axial direction of the roller shaft, and the air-cooling channels are multiple channels distributed in a circular array.
[0009] Furthermore, a serpentine tube is connected to the air outlet duct. The serpentine tube is located inside the liquid cooling box, and its end penetrates through the liquid cooling box and is connected to multiple air-cooling ducts.
[0010] Furthermore, the sidewall of the serpentine tube is provided with multiple heat dissipation fins.
[0011] Furthermore, an arc-shaped pipe is connected to the end of the air outlet pipe, and multiple air-cooling pipes are distributed in an arc shape and connected to the arc-shaped pipe at the same time.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] 1. The structure of this utility model involves placing the roller shaft outside the rotating shaft, with an air inlet and an air outlet at each end of the rotating shaft. An air inlet pipe and an air outlet pipe are rotatably connected to the air inlet and air outlet respectively. Multiple air-cooling channels are arranged inside the roller shaft, and multiple lower air ducts are connected to both the air inlet and air outlet. Upper air ducts are connected to both ends of each air-cooling channel, and the upper and lower air ducts are interconnected. This structure allows external cold air to enter the air inlet of the rotating shaft through the air inlet pipe under the action of the fan, and then... Multiple downdrafts and updrafts connect to multiple air-cooling channels on the roller, and then the air is discharged from the outlet pipe at the air outlet through multiple downdrafts and updrafts connected at the other end of the air-cooling channels. This structure allows the cold air from the outside to pass through multiple air-cooling channels inside the roller for cooling, which greatly increases the contact area between the cold air and the roller, cools the roller from the inside, further improves the cooling effect, reduces the amount of glue residue on the roller surface, ensures the smoothness of the material output after the pad is laminated, and ensures the quality of the pad laminate processing.
[0014] 2. A liquid cooling box and multiple air-cooling pipes are installed below the roller. The air outlet pipes extend into the liquid cooling box, and the end of the air outlet pipe passes through the liquid cooling box and connects with multiple air-cooling pipes. The air-cooling pipes are equipped with multiple air nozzles facing the roller. This structure allows the hot air generated after cooling the roller to enter the liquid cooling box for cooling. The cooled air is then blown onto the surface of the roller through the air nozzles on the multiple air-cooling pipes for further cooling. This structure combines air cooling with liquid cooling, further improving the cooling effect. Moreover, the liquid cooling liquid does not need to enter the interior of the roller, thus not increasing the load on the roller rotation. This simplifies the complexity of the structure, reduces the energy consumption of the equipment, and greatly improves the cooling effect on the roller. Attached Figure Description

Detailed Implementation
[0021] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.
[0022] Reference Figure 1 and Figure 2This utility model describes a roller cooling device for a pad laminating machine. The main structure includes a rotating shaft 2 rotatably connected to a machine body 1 via bearings. The machine body 1 is the main part of the laminating machine, used for gluing and laminating pads. The rotating shaft 2 is driven to rotate by a motor and gears. A roller shaft 3 is fixed to the outside of the rotating shaft 2 by welding or bolts. The roller shaft 3 directly contacts the laminated pad, thereby driving the pad to discharge. The rotating shaft 2 has an air inlet 4 and an air outlet 5 at both ends, extending axially inward from the ends of the rotating shaft 2. An air inlet pipe 6 and an air outlet pipe 7 are rotatably connected to the air inlet 4 and air outlet 5, respectively. The air inlet pipe 6 is connected to a fan or other equipment to pump external cold air into it. The roller 3 has multiple air-cooling channels 8 inside, forming multiple hollow structures within the roller 3. This increases the contact area with the cold air, significantly improving the cooling effect. Multiple lower air ducts 9 are connected to both the air inlet 4 and the air outlet 5, extending from their positions to the outer wall of the rotating shaft 2. Upper air ducts 10 are connected to both ends of each air-cooling channel 8, extending from their ends to the inner wall of the roller 3. The lower air ducts 9 and upper air ducts 10 are connected. This structure allows both the air inlet 4 and the air outlet 5 to be connected to multiple air-cooling channels 8 via the connected lower and upper air ducts 9 and 10, thus enabling the cold air entering from the air inlet 4 to simultaneously enter multiple air-cooling channels 8. The air is then discharged from the air outlet 5, which quickly removes the heat inside the roller 3, increases the contact area between the cold air and the roller 3, and further improves the cooling effect. A liquid cooling box 11 is located below the roller 3. The liquid cooling box 11 is fixed to the ground below the roller 3 by welding or bolts. The inner wall is wrapped with insulation material to slow down heat exchange with the outside environment. The liquid cooling box 11 is equipped with an inlet pipe 12 and an outlet pipe 13. Cooling water enters the liquid cooling box 11 from the inlet pipe 12 under the action of a water pump. After heat exchange, the cooling water is discharged from the outlet pipe 13, maintaining a continuous low temperature inside the liquid cooling box 11 to ensure the liquid cooling effect. The air outlet 7 extends into the liquid cooling box 11. The higher-temperature cold air inside the air outlet 7 is cooled by passing through the side wall of the air outlet 7 and... The cooling water inside the liquid cooling box 11 undergoes heat exchange, thereby reducing the gas temperature inside the air outlet duct 7. Multiple air-cooling pipes 14 are located below the roller 3, and each air-cooling pipe 14 has multiple air nozzles 15 facing the roller 3. The end of the air outlet duct 7 passes through the liquid cooling box 11 and connects to the multiple air-cooling pipes 14. With this structure, after the liquid cooling box 11 cools the gas, the cooled gas is blown along the air nozzles 15 on the multiple air-cooling pipes 14 onto the surface of the roller 3. This combines air cooling with liquid cooling to further cool the gas, simultaneously cooling the roller 3 from both the inside and outside, greatly improving the air cooling effect. Furthermore, the liquid cooling liquid does not need to enter the interior of the roller 3, thus not increasing the load on the roller 3's rotation and simplifying the complexity of the device.This reduced the energy consumption of the equipment and significantly improved the cooling effect on roller 3.
[0023] Preferably, the body 1 is symmetrically fixed with upright plates 16 by welding or bolts, and the two ends of the rotating shaft 2 are rotatably connected to the upright plates 16 on both sides by bearings. This structure uses the upright plates 16 on both sides to support the rotating shaft 2, which facilitates the connection of the two ends of the rotating shaft 2 with the air inlet pipe 6 and the air outlet pipe 7, and leaves enough connection space for the drive structure of the rotating shaft 2, thereby improving the smoothness of the cooperation between the structure of the rotating shaft 2 and the air inlet system.
[0024] Preferred, refer to Figure 3 The upright plates 16 on both sides are respectively provided with rotary joints 17 that communicate with the air inlet pipe 6 and the air outlet pipe 7. The rotary joints 17 can adopt the joint structure used in the prior art for rotating and connecting gas pipelines. Specifically, the rotary joint of model SCB produced by Jiangsu Tengxuan Technology Co., Ltd. can be used. The two ends of the rotating shaft 2 are respectively connected to the rotary joints 17 on both sides. This structure ensures that the air inlet pipe 6 and the air outlet pipe 7 are connected to the rotating shaft 2 without affecting the rotation of the rotating shaft 2, thus ensuring the smoothness of the air-cooled air intake system.
[0025] Preferably, the air-cooling channel 8 extends along the axial direction of the roller shaft 3, and the air-cooling channel 8 is a plurality of circular arrays. This structure allows the plurality of circular arrays of air-cooling channels 8 to cover various positions inside the roller shaft 3, further increasing the contact area for air-cooling and improving the cooling effect on the roller shaft 3.
[0026] Preferably, a serpentine pipe 18 is connected to the air outlet duct 7. The serpentine pipe 18 is a wavy, curved pipe structure. The serpentine pipe 18 is located inside the liquid cooling box 11. Its shape can greatly increase the contact area between the pipe and the cooling water inside the liquid cooling box 11. The end of the serpentine pipe 18 passes through the liquid cooling box 11 and is connected to multiple air-cooling pipes 14. With the serpentine pipe 18 connected to the end of the air outlet duct 7, the serpentine pipe 18 exchanges heat with the cooling water inside the liquid cooling box 11, thereby greatly improving the heat exchange efficiency of the hot air inside the air outlet duct 7 and improving the effect of subsequent air-cooling.
[0027] Preferably, multiple heat dissipation fins 19 are fixed on the side wall of the serpentine tube 18 by welding or integral molding. The heat dissipation fins 19 can further increase the contact area between the side wall of the serpentine tube 18 and the cooling water, improve the heat exchange of the hot air in the serpentine tube 18 per unit time, and further improve the heat exchange efficiency.
[0028] Preferred, refer to Figure 4The end of the air outlet pipe 7 is connected to an arc-shaped pipe 20 by welding or integral forming. Multiple air-cooling pipes 14 are distributed in an arc shape and connected to the arc-shaped pipe 20 at the same time. This structure makes the coverage area of the multiple arc-shaped air-cooling pipes 14 on the side of the roller shaft 3 larger, thereby increasing the contact range between the cold air and the side of the roller shaft 3 and improving the air-cooling efficiency of the side of the roller shaft 3.
[0029] Working principle: The structure of this utility model places the roller shaft 3 outside the rotating shaft 2. An air inlet 4 and an air outlet 5 are respectively provided at both ends of the rotating shaft 2. An air inlet pipe 6 and an air outlet pipe 7 are rotatably connected to the air inlet 4 and air outlet 5, respectively. Multiple air-cooling channels 8 are provided inside the roller shaft 3. Multiple lower air ducts 9 are connected to both the air inlet 4 and air outlet 5. Upper air ducts 10 are connected to both ends of the air-cooling channels 8, and the upper air ducts 10 are connected to the lower air ducts 9. This structure allows the external... The cold air, driven by the fan, enters the air inlet 4 of the rotating shaft 2 through the air inlet pipe 6. Then, it enters the multiple cooling channels 8 on the roller shaft 3 through multiple lower air ducts 9 and upper air ducts 10 connected at the air inlet 4. Finally, it exits through the air outlet 7 at the air outlet 5 along the multiple lower air ducts 9 and upper air ducts 10 connected at the other end of the cooling channels 8. This structure allows the outside cold air to pass through the multiple cooling channels 8 inside the roller shaft 3 for cooling, greatly increasing the contact area between the cold air and the roller shaft 3, thus reducing the temperature from the inside. Cooling the roller 3 further improves the cooling effect, reduces the amount of glue residue on the surface of the roller 3, ensures the smoothness of material discharge after the pad is laminated, and guarantees the quality of the pad lamination process. A liquid cooling box 11 and multiple air cooling pipes 14 are provided below the roller 3. The air outlet pipe 7 extends into the liquid cooling box 11, and the end of the air outlet pipe 7 passes through the liquid cooling box 11 and connects to multiple air cooling pipes 14. Multiple air nozzles 15 are provided on the air cooling pipes 14 facing the roller 3. This structure allows the hot air generated after cooling the roller 3 to enter the liquid cooling box 11 for cooling. The cooled air is then blown onto the surface of the roller 3 through the air nozzles 15 on the multiple air cooling pipes 14 for cooling. This structure combines air cooling with liquid cooling, further improving the cooling effect. Moreover, the liquid cooling liquid does not need to enter the interior of the roller 3, which does not increase the load on the rotation of the roller 3, simplifies the complexity of the structure, reduces the energy consumption of the equipment, and greatly improves the cooling effect of the roller 3.
