Description

Technical Field

[0001] The utility model relates to the field of cooling and transportation of solid polyester resin, in particular to a steel belt cooling system of solid polyester resin for powder coating. Background Art

[0002] Powder coating is a kind of coating in the form of solid powder particles, which is applied to the surface of an object by electrostatic spraying or powder spraying, and then melted and solidified into a coating film at high temperature. Polyester resin is one of the main components of powder coating. As a high-performance coating, polyester resin powder coating is widely used in many fields such as metal coating, home appliance manufacturing, architectural decoration, automobile industry, electronics industry and transportation facilities, providing protection and beautification effects for products. At the same time, polyester resin powder coatings also have the advantages of being solvent-free, environmentally friendly, and energy-saving. It has become a trend to gradually replace traditional liquid coatings. Existing powder coatings require the use of steel belt conveyors to transport high-temperature polyester resins in powder coatings during production. Since polyester resins are highly stable and have low cooling efficiency, the steel belt needs to be cooled with the help of external conditions during its production process to ensure stable operation of the steel belt and assist in rapid cooling and solidification of the high-temperature polyester resin. However, when cooling the steel belt, the staff currently usually sets some cooling equipment at the lower end of the steel belt to cool the steel belt. However, the temperature of the drive roller at the output end of the steel belt conveyor will gradually increase under the action of the high-temperature polyester resin for a long time, causing the heat inside the roller to transfer to the steel belt, reducing the temperature difference between the steel belt at the output end of the steel belt conveyor and the high-temperature polyester resin, thereby reducing the cooling efficiency of the steel belt at the output end of the steel belt conveyor, thereby affecting the use effect of the steel belt.

[0026] Reference Figure 1-5 The utility model provides an embodiment: a steel belt cooling system for solid polyester resin for powder coating, comprising a bearing heat dissipation bracket 1:

[0027] The driving roller 9 is arranged on both sides of the bearing heat dissipation bracket 1. There are two driving rollers 9. Both the front and rear ends of the two driving rollers 9 are equipped with connecting rotating brackets 10. The installation of the connecting rotating brackets can play the role of rotating seals. Under the premise of ensuring that the driving roller 9 can rotate freely, it is ensured that the connecting hose 4 can be stably connected to the bearing heat dissipation bracket 1 to ensure stable operation of the device. The connecting rotating bracket 10 is rotatably connected to the driving roller 9 through a card slot. The external annular array of the connecting rotating bracket 10 has four connecting capillaries 11. A middle rotating shaft 17 is installed inside the connecting rotating bracket 10. The middle rotating shaft 17 is rotatably connected to the connecting rotating bracket 10 and the bearing heat dissipation bracket 1.

The installation of the spiral conveying bracket 14 can make the driving roller 9 rotate, and the spiral conveying bracket 14 can rotate synchronously to convey the cooling water inside the driving roller 9, so that the cooling water can flow inside the driving roller 9, and then the cooling water can flow to the driving roller 9. Roller 9 is cooled to avoid the temperature increase of driving roller 9 at the output end of the steel belt conveyor, and to ensure that the temperature difference between the transport cooling steel belt 5 at the output end of the steel belt conveyor and the high-temperature polyester resin is always kept at the maximum, thereby avoiding the cooling efficiency of the transport cooling steel belt 5 at the output end of the steel belt conveyor being reduced, and ensuring the use effect of the transport cooling steel belt 5. A filter basket 15 is installed at the rear end of the outside of the middle rotating shaft 17, and the filter basket 15 is welded to the driving roller 9. The installation of the filter basket 15 can filter the cooling water inside the device to prevent impurities in the cooling water from clogging the device, effectively extending the service life of the device, and ensuring the stable and smooth flow of cooling water.

The drive connection bracket 13 is set so that the middle rotating shaft 17 can stably drive the driving roller 9 to rotate, ensuring the complete functionality of the device;

[0028] The transport cooling steel belt 5 is arranged on the outside of the driving roller 9, and a plurality of hollow heat dissipation holes 8 are arranged inside the transport cooling steel belt 5. The hollow heat dissipation holes 8 can make the contact area between the hollow heat dissipation holes 8 and the air larger, which is beneficial to the efficient heat dissipation of the transport cooling steel belt 5, improves the use effect of the transport cooling steel belt 5, and reduces the weight of the transport cooling steel belt 5, making the device more convenient to transport. Trapezoidal connecting pipes 16 are installed at the front and rear ends of the heat dissipation support 1, and a connecting hose 4 is installed at one end of the trapezoidal connecting pipe 16. A chiller 3 is arranged at one end of the connecting hose 4. The chiller 3 is a prior art and will not be described here.

[0029] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5Limiting heat conducting plates 7 are installed at both upper and lower ends of the inner side of the bearing heat dissipation bracket 1. The installation of the limiting heat conducting plates 7 can prevent the transport cooling steel belt 5 from jumping, and limit the transport cooling steel belt 5. At the same time, the transport cooling steel belt 5 is in contact with the limiting heat conducting plates 7, and heat exchange can be performed in a heat price rotation manner to improve the practicality of the device. The limiting heat conducting plates 7 are welded and connected to the bearing heat dissipation bracket 1. Four limiting heat conducting plates 7 are provided. Cooling water is provided inside the bearing heat dissipation bracket 1. The rotating bracket 10 is connected to the driving roller 9 for sealing. A driving motor 6 is installed on one side of the front end surface of the bearing heat dissipation bracket 1. The driving motor 6 and the bearing heat dissipation bracket 1 are connected by screws.

[0030] The specific use process of the utility model is as follows: the chiller 3 is started, and the chiller 3 injects cold water into the load-bearing heat dissipation bracket 1 through the connecting hose 4 at the front end of the device. A part of the cooling water in the load-bearing heat dissipation bracket 1 enters the interior of the driving roller 9 through the connecting capillary 11 in front of the driving roller 9, and then the driving motor 6 drives the middle rotating shaft 17 to rotate, and the middle rotating shaft 17 drives the driving roller 9 to rotate by driving the connecting bracket 13, and then the driving roller 9 drives the transport cooling steel belt 5 to move, and finally the polyester resin at the upper end of the transport cooling steel belt 5 is transported. When the polyester resin is transported, the high-temperature polyester resin will continuously exchange heat with the transport cooling steel belt 5, and a part of the heat of the transport cooling steel belt 5 will pass through the load-bearing heat dissipation bracket 1 and the cooling water in the load-bearing heat dissipation bracket 1. Heat exchange is performed to reduce the temperature of the transport cooling steel belt 5. Part of the heat in the transport cooling steel belt 5 will be absorbed by the driving roller 9. At this time, the cooling water inside the driving roller 9 will perform heat exchange with the driving roller 9 to reduce the temperature of the driving roller 9. The middle rotating shaft 17 will drive the spiral conveying bracket 14 to rotate when rotating, and the rotation of the spiral conveying bracket 14 will disturb the cooling water inside the driving roller 9 to move, so that the cooling water with increased temperature will re-enter the inside of the bearing heat dissipation bracket 1 through the connecting capillary 11 behind the driving roller 9. When the cooling water inside the driving roller 9 moves, the impurities in the cooling water will be intercepted by the filter basket 15 to ensure the cleanliness of the water quality inside the device. Then the cooling water with increased temperature inside the bearing heat dissipation bracket 1 will flow back into the chiller 3 through the connecting hose 4 on the rear end face of the device. The cooling treatment is carried out inside, and then the cooling water repeats the above operation and circulates continuously inside the device. The device is installed with a connecting rotating bracket to play the role of a rotating seal. Under the premise of ensuring that the driving roller 9 can rotate freely, it is ensured that the connecting hose 4 can be stably connected to the load-bearing heat dissipation bracket 1 to ensure stable operation of the device. The spiral conveying bracket 14 can be installed to make the driving roller 9 rotate synchronously when the driving roller 9 rotates, and the cooling water inside the driving roller 9 is conveyed, so that the cooling water can flow inside the driving roller 9, and then the cooling water cools the driving roller 9, avoiding the temperature of the driving roller 9 at the output end of the steel belt conveyor to rise, ensuring that the temperature difference between the cooling steel belt 5 transported at the output end of the steel belt conveyor and the high-temperature polyester resin is always kept at the maximum, thereby avoiding the steel belt transportation. The cooling efficiency of the transport cooling steel belt 5 at the output end of the machine is reduced, and the use effect of the transport cooling steel belt 5 is ensured. The installation of the filter basket 15 can filter the cooling water inside the device to prevent impurities in the cooling water from clogging the device, effectively extending the service life of the device and ensuring the stable and smooth flow of cooling water. The drive connection bracket 13 is set to enable the middle rotating shaft 17 to stably drive the driving roller 9 to rotate, ensuring the functional integrity of the device. The hollow heat dissipation holes 8 are set to increase the contact area between the hollow heat dissipation holes 8 and the air, which is conducive to the efficient heat dissipation of the transport cooling steel belt 5, improves the use effect of the transport cooling steel belt 5, and reduces the weight of the transport cooling steel belt 5, making the device more convenient to transport. The installation of the limiting heat conducting plate 7 can prevent the transport cooling steel belt 5 from jumping.The transport cooling steel belt 5 is limited, and at the same time the transport cooling steel belt 5 is in contact with the limit heat conducting plate 7, so that heat exchange can be performed in a heat price rotation manner, thereby improving the practicality of the device.
