Description

Technical Field

[0001] The utility model relates to the technical field of color-coated plate processing, in particular to a color-coated plate rapid cooling device. Background Art

[0002] Color-coated steel sheets are a composite material widely used in construction, home appliances, and other fields. Their surface coatings require a cooling process during production to ensure the coating solidifies and forms its shape. However, existing cooling technologies for color-coated steel sheets have limitations and cannot fully meet the stringent cooling speed and uniformity requirements for efficient production.

[0003] Existing technologies typically use single-sided cooling or simple cooling fan systems to cool color-coated steel sheets. However, this single-sided cooling method can easily lead to uneven surface temperatures on the steel sheets. Particularly on high-speed production lines, insufficient cooling can cause large temperature differences in certain areas. These temperature differences often cause thermal deformation on the steel sheet surface, impacting sheet flatness and product quality. Furthermore, conventional cooling systems lack effective contamination control measures for coolant recycling, which can lead to impurities in the coolant re-contaminating the steel sheet surface and reducing its surface finish.

[0004] To this end, we propose a rapid cooling device for color-coated plates. Utility Model Content

[0012] Beneficial effects

[0013] The utility model provides a rapid cooling device for color-coated plates. It has the following beneficial effects:

[0014] 1. Rapid Cooling: This color-coated steel plate rapid cooling device utilizes two corresponding cooling mechanisms, one above the other, to achieve simultaneous cooling of the upper and lower surfaces of the color-coated steel plate. The cooling mechanisms utilize high-pressure spray nozzles, combined with the reciprocating motion of the cooling chamber, to ensure that the coolant is evenly sprayed across the surface of the color-coated steel plate, preventing any areas of insufficient cooling. This significantly improves cooling speed and uniformity, ensuring temperature control for efficient production.

[0015] 2. Uniform Cooling: The cooling chamber of this color-coated steel plate rapid cooling device swings back and forth through gear meshing driven by a motor assembly, increasing the coolant spray coverage area. By simultaneously cooling both the top and bottom surfaces of the color-coated steel plate, the plate is evenly stressed throughout the cooling process, avoiding deformation or uneven cooling caused by large local temperature differences and ensuring consistent product quality.

[0016] 3. Preventing secondary contamination from impurities: This color-coated plate rapid cooling device is equipped with a guide baffle and filter screen inside the processing chamber. Coolant dripping from the color-coated plate surface is guided into the grooves by the guide baffle, where it is filtered out by the filter screen. This prevents impurities from circulating with the coolant and entering the cooling mechanism, preventing secondary contamination of the color-coated plate surface and thus ensuring the surface finish and product quality of the color-coated plate.

[0017] 4. Structural stability and transmission efficiency: This color-coated plate rapid cooling device utilizes a dual-gear meshing design. Two sets of half gears are mounted on the motor's output shaft, mating with the main gear on the rotating shaft to prevent gear slippage. This dual-gear design not only improves transmission efficiency but also enhances operational stability, reducing the risk of gear wear after prolonged use. This ensures smooth oscillation of the cooling mechanism and extends the device's service life.

[0018] 5. Maintenance Ease: The nozzle assembly of this color-coated plate rapid cooling device features a detachable design. The nozzle and butt-joint pipe are connected by a flange ring and fasteners, making it easy to disassemble and clean. Regular nozzle maintenance and cleaning not only ensures long-term stable operation of the equipment but also effectively prevents uneven coolant spraying, thereby reducing failure rates, minimizing maintenance downtime, and improving production efficiency.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Example: A rapid cooling device for color-coated plates, such as Figure 1 - Figure 6As shown, it includes a processing box 1, and connection ports 101 are opened at the front and rear ends of the processing box 1. A color-coated plate body 2 and a conveying roller 102 for driving the color-coated plate body 2 to move back and forth are arranged inside the processing box 1. It is characterized in that: two sets of cooling mechanisms corresponding to the upper and lower parts are arranged inside the processing box 1, and the color-coated plate body 2 passes through the two sets of cooling mechanisms corresponding to the upper and lower parts through the conveying roller 102. A water circulation mechanism is arranged outside the processing box 1, and the water circulation mechanism is connected to the bottom of the processing box 1 and the corresponding cooling mechanism through a water pipe. The outside of the processing box 1 is provided with a mechanism for driving the corresponding cooling mechanism to circulate back and forth. The motor assembly of the ring swings; each of the cooling mechanisms includes cooling boxes 3 located on the upper and lower sides of the color-coated plate body 2, and both ends of the cooling box 3 are connected with a rotating shaft rod 301 that is movably connected to the inner side of the processing box 1. The bottom of the cooling box 3 is connected with a connecting box body 302, and a row of detachable nozzle assemblies are provided at the bottom of the connecting box body 302. A main gear 305 is sleeved on the rotating shaft rod 301, and the motor assembly includes a motor body 4 installed on the outside of the processing box 1. The output shaft of the motor body 4 is connected to the rod inside the processing box 1, and a half gear 401 is installed on the rod, and the half gear 401 meshes with the main gear 305. The motor body 4 is connected to each other, wherein two sets of half gears 401 are sleeved on the output shaft of each of the motor bodies 4, and two sets of main gears 305 are also provided on the rotating shaft rod 301 corresponding to the half gears 401. By providing two sets of half gears 401 on the motor assembly, two sets of matching main gears 305 are provided on the driven cooling mechanism, and the two sets of half gears 401 and the two sets of main gears 305 are meshed with each other. When the teeth of the half gear 401 drive the teeth of the main gear 305 to fit, the motor body 4 drives the corresponding cooling mechanism to swing, and when the other half of the half gear 401 without teeth rotates to the main gear When the teeth on the main gear 305 are turned, the driving mechanism resumes swinging in the opposite direction of the swing. When the half gear 401 rotates half a circle, the teeth on the half gear 401 re-engage with the teeth of the main gear 305, and the cooling mechanism is driven to swing again. The nozzle assembly on the swinging cooling mechanism swings back and forth on the upper and lower surfaces of the color-coated plate body 2. The two groups of cooling assemblies are started at the same time, further uniformly and quickly cooling the upper and lower surfaces of the conveyed color-coated plate body 2, and the two groups of half gears 401 are meshed with the main gear 305 to avoid the situation where the teeth between one group of main gears 305 and the half gear 401 slip and affect the drive.

[0031] The nozzle assembly includes a docking tube 303 connected to the interior of the connecting box body 302, and a high-pressure spray nozzle 304 is arranged below the docking tube 303. The high-pressure spray nozzle 304 and the docking tube 303 are both sleeved with matching flange rings. The high-pressure spray nozzle 304 and the corresponding docking tube 303 are connected by fasteners and flange ring threads. In this technical solution, a detachable nozzle assembly, a detachable nozzle and a cleaning interface are provided to facilitate regular maintenance and cleaning.

[0032] The water circulation mechanism includes a water pump 5 and a delivery pipe assembly 501 installed on the outside of the processing box 1. The delivery pipe assembly 501 is composed of a plurality of water pipes connected and assembled. The upper ends are respectively connected to the cooling box 3 inside the corresponding processing box 1. The connection of the plurality of water pipes is controlled by a valve. The plurality of water pipes are connected. The delivery pipe assembly 501 is connected to the motor body 4 inside the corresponding processing box 1. The lower end of the water pump 5 is connected to the output end pipeline of the water pump 5. The input end of the water pump 5 is connected to the inside of the processing box 1 through the water pipe. The water circulation mechanism processes the processing The coolant solution on the bottom surface of the box 1 is transported to the delivery pipe assembly 501 by the water pump 5, and then transported to the corresponding cooling box 3 through the delivery pipe assembly 501. The aqueous solution in the corresponding cooling box 3 flows into the connecting box 302 and the corresponding nozzle assembly. The aqueous solution is sprayed on the corresponding surface of the color-coated plate body 2 through the swinging nozzle assembly to cool it down. The aqueous solution on the surface of the color-coated plate body 2 will drip back onto the inner bottom surface of the processing box 1, and will be transported to the cooling box 3 again through the water pump 5, forming a aqueous solution circulation system.

[0033] like Figure 5 As shown, in order to prevent impurities from re-entering the cooling mechanism along with the water flow when the color-coated plate body 2 is cooled, a guide baffle 103 located below the cooling mechanism is provided inside the processing box 1 in the present technical solution. The guide baffle 103 is provided with a groove, and a filter screen 104 is installed on the bottom surface of the groove of the guide baffle 103. By providing the guide baffle 103 and the filter screen 104 located below the cooling mechanism inside the processing box 1, the guide baffle 103 guides the coolant dripping from the upper end of the color-coated plate body 2 into the groove thereon, and then filters and screens it through the filter screen 104 to prevent impurities from falling into the coolant on the bottom surface of the processing box 1, and to prevent impurities from re-flowing into the cooling mechanism along with the water circulation mechanism, causing surface contamination to a new round of color-coated plate bodies 2.

[0034] The working principle of the present invention is as follows: the color-coated plate body 2 enters from the connection port 101 at one end of the processing box 1, and is driven by the conveying roller 102 inside the processing box 1 to pass through two groups of cooling mechanisms. Each group of cooling mechanisms is driven to swing back and forth by the corresponding motor assembly, and at the same time, cooperates with the water circulation mechanism to convey the cooling water inside the processing box 1 to the corresponding cooling mechanism along with the water pump 5. The high-pressure spray nozzle 304 on the cooling mechanism drives the aqueous solution to swing back and forth along with the motor assembly, and evenly sprays the aqueous solution on the upper and lower layers of the color-coated plate body 2 for cooling. The back-and-forth swinging cooling mechanism can increase the relative spraying area on the color-coated plate body 2, accelerate the rapid cooling of the color-coated plate body 2, and the swinging uniform spraying can evenly dissipate the heat on the color-coated plate body 2, avoiding the occurrence of uneven cooling on the plate surface of the color-coated plate body 2. The two groups of cooling mechanisms evenly dissipate the heat on the upper and lower sides of the color-coated plate body 2 passing through them twice, further enhancing the heat dissipation effect of the color-coated plate body 2.

[0035] The main effect of the color-coated plate rapid cooling device is achieved through the close cooperation of a series of structures. Its core structure includes cooling mechanism, motor assembly, conveying system, water circulation system, etc. The specific effect analysis is as follows:

[0036] Rapid cooling effect: Cooling mechanism: The upper and lower sets of cooling boxes surround the color-coated plate body, and the coolant is evenly sprayed through the nozzle assembly to achieve a rapid cooling effect.

[0037] Motor assembly and gear system: The back-and-forth swing of the cooling box (achieved by the motor assembly driving the gear meshing) can increase the spray area of the coolant, making the cooling uniform and avoiding the phenomenon of insufficient local cooling.

[0038] Water circulation system: The water pump continuously pumps the coolant into the cooling box through the delivery pipe assembly, and the water solution is recycled to improve efficiency and save resources.

[0039] Uniform cooling effect:

[0040] The synchronous cooling of the upper and lower sides of the cooling box can make the upper and lower surfaces of the color-coated plate body cool evenly at the same time, avoiding plate deformation or surface unevenness caused by large temperature difference on one side.

[0041] The back-and-forth swing of the cooling box allows the nozzle to spray evenly over the entire surface of the color-coated plate body, avoiding the cooling blind spot problem that may be caused by a stationary nozzle.

[0042] Maintainability:

[0043] Removable nozzle assembly: By setting up a detachable nozzle and cleaning interface, the nozzle assembly can be easily maintained and cleaned, extending the service life of the equipment and reducing the failure rate.

[0044] Impurity filtration:

[0045] Guide baffle and filter plate: After the coolant is sprayed, it will drip back into the processing box. The coolant will be guided into the filter plate through the groove of the guide baffle to filter out impurities, prevent impurities from circulating into the cooling system, and protect the surface of the color-coated plate from secondary contamination.

[0046] Reduce gear wear and improve transmission efficiency:

[0047] Dual-gear design: Two sets of half gears and a main gear are set on each motor output shaft and rotating shaft. Through meshing, the risk of excessive wear of a single gear is reduced, the transmission efficiency of the gear is improved, and the long-term stable operation of the equipment is ensured.

[0048] Advantages Summary

[0049] Efficient cooling: Through upper and lower side cooling and back and forth swinging, cooling is faster and more uniform, which improves the efficiency of color-coated plate production.

[0050] Stable structure: The double gear meshing design prevents transmission problems such as gear slippage, ensuring the stability and service life of the equipment.

[0051] Strong maintainability: The detachable design of the nozzle assembly and the filtration design of the water circulation system facilitate maintenance, extend the life of the equipment and reduce operating costs.

[0052] Energy saving and environmental protection: The water circulation system can reuse cooling water, reduce water waste, and meet the requirements of energy saving and environmental protection.

[0053] Through ingenious structural design, such as double-sided cooling, gear transmission, motor swing, detachable nozzle and water circulation system, the utility model not only achieves rapid and uniform cooling of color-coated plates, but also has the advantages of convenient maintenance and high efficiency and energy saving, and is suitable for large-scale industrial applications.
