Description

Technical Field

[0001] The utility model relates to the technical field of powder spraying and curing, and more particularly to a powder spraying and curing device. Background Art

[0002] In the existing powder spray curing technology, there are multiple methods to complete the coating curing process, but each method faces challenges and limitations to varying degrees. These problems not only affect production efficiency, but may also lead to unstable product quality, thereby affecting the reliability and economic benefits of the entire production process. The most traditional method is to cure the coating by natural drying. Although this method is simple, it has many disadvantages: high time cost, natural drying usually takes hours or even days to complete, seriously extending the production cycle; large space requirements, in order to wait for the coating to cure, a large amount of storage space is required to place the products to be cured; unstable quality, environmental factors such as temperature and humidity changes will directly affect the curing effect, resulting in inconsistent coating quality; high energy consumption, long-term occupation of factory space means continuous energy consumption such as lighting and ventilation; production planning is difficult to optimize, due to the uncertainty of curing time, it is difficult to accurately arrange subsequent production steps.

[0003] Secondly, some equipment uses fans to deliver drying air to accelerate the curing process. This method is an improvement over natural drying, but it still has obvious shortcomings: the structure is too simple, and most equipment is only equipped with a basic fan system and lacks fine control; the wind speed is fixed and the drying wind speed cannot be adjusted according to the characteristics of different products or coatings; the energy efficiency is low, and the fixed wind speed may lead to energy waste in some cases, while being insufficient in other cases; the curing is uneven, and the simple fan system may cause uneven heating of the product surface, affecting the coating quality; the adaptability is poor, and it is difficult to adapt to products of different sizes and shapes or different process requirements.

[0004] Finally, although some equipment has introduced designs with adjustable drying air speed, these improvements often ignore the stability of the overall structure, leading to new problems: the adjustment mechanism is simple and the anti-interference ability is weak. The vibration of the equipment during operation may cause the adjustment device to shift, and long-term stable operation cannot be guaranteed; the curing conditions between different batches of products are difficult to maintain consistency, affecting the stability of product quality. Although these equipment have designed some devices to achieve the adjustment of the drying air delivery speed, their structure is simple and ignores the problem of structural stability, which can easily cause the adjusted delivery speed to change due to factors such as equipment vibration.

[0018] Beneficial effects:

[0019] 1. The curing device realizes the effective transmission and utilization of drying air by setting up components such as air inlet bin, buffer bin and fan. This structural design ensures the stable supply and uniform distribution of drying air. The detachable baking lamp in the curing box provides an additional heat source, which accelerates the curing process.

[0035] In this embodiment, when it is necessary to adjust the delivery speed of the drying air, the control plate 17 is first rotated so that the control plate 17 drives the arc groove 18 and the circular groove 19 to move. When the circular groove 19 moves to a position concentric with the round rod 20, the locking sleeve 14 is pushed so that the locking sleeve 14 drives the round rod 20 and the circular plate 21 to pass through the circular groove 19, and the locking sleeve 14 and the control plate 17 cooperate to squeeze the push spring 23. When the push spring 23 is squeezed to the limit, the corresponding circular plate 21 just passes through the circular groove 19 and reaches the other side of the control plate 17. Then the control plate 17 is rotated in the opposite direction so that the control plate 17 drives the arc groove 18 and the circular groove 19 to move, and then the round rod 20 will enter the arc groove 18, and at the same time the locking sleeve 14 will pass through the round rod 20 and the corresponding The cooperation of the circular plate 21 is limited to one side of the control plate 17. At this time, the locking rod 16 loses the limit of the locking sleeve 14, and then the rotating sleeve 5 is rotated. The rotating sleeve 5 will drive the locking rod 16 to move, and then the side wall of the locking groove 15 will squeeze one end of the locking rod 16. Due to the rounded structure at the end of the locking rod 16 and the edge of the locking groove 15, one end of the locking rod 16 will slide out of the locking groove 15, and then the other end of the locking rod 16 will drive the connecting spring 13 to stretch. At the same time, the rotating sleeve 5 will drive the adapter sleeve 12 to rotate through the connecting rod 22. Since the inner side of the adapter sleeve 12 and the adapter rod 11 are both prismatic structures, the adapter sleeve 12 will drive the adapter rod 11 to rotate, and then the adapter rod 11 will simultaneously drive the blocking rod 8 and the matching rod connected at both ends. 7 rotates, since the matching rod 7 and the matching sleeve 6 are movably connected by a thread, the matching rod 7 will move spirally along the matching sleeve 6, and then the matching rod 7 will drive the adapter rod 11 to slide along the adapter sleeve 12, and then the adapter rod 11 will drive the blocking rod 8 connected at the other end to move in the circulation tube 10, so that the number of the flow holes 9 opened on the side wall of the circulation tube 10 changes, thereby changing the volume of the drying air passing through, thereby achieving the purpose of adjusting the drying air delivery speed. After the adjustment is appropriate, stop rotating the rotating sleeve 5, and make the connecting spring 13 drive the locking rod 16 to reset, so that the other end of the locking rod 16 is inserted into the corresponding locking groove 15, and then rotate the control plate 17 again, so that the control plate 17 drives the arc groove again 18 and the circular groove 19 rotate. When the circular groove 19 moves to the position corresponding to the circular plate 21, the push spring 23 pushes the locking sleeve 14 to drive the round rod 20 and the circular plate 21 to slide and reset. When the push spring 23 is completely reset, the control plate 17 is rotated again, so that the control plate 17 drives the arc groove 18 and the circular groove 19 to move to a position that does not correspond to the round rod 20 and the circular plate 21, so that the round rod 20 and the circular plate 21 cooperate to limit the locking sleeve 14 to prevent the locking sleeve 14 from sliding, and then the locking sleeve 14 will limit the locking rod 16, and then the locking rod 16 and the locking groove 15 cooperate to limit the rotating sleeve 5 to prevent the rotating sleeve 5 from moving, thereby preventing the adjusted flow rate from changing easily, greatly improving the structural stability.

[0037] A baking lamp 27 is detachably provided in the curing box 1 .

[0038] A connecting chamber 28 is provided on both sides of the curing box 1. A connecting pipe 29 is connected to the outside of the connecting chamber 28. The other end of the connecting pipe 29 is connected to the side wall of the air inlet chamber 24. A fan 30 is detachably provided in the connecting chamber 28.

[0040] A conveyor 32 is provided below the curing box 1 , and an observation window 33 is provided on one side of the curing box 1 .

[0041] More specifically, when the equipment needs to be used, the parts after powder spraying are first conveyed to the conveyor 32, and then the conveyor 32 is turned on, so that the conveyor 32 drives the parts to move into the curing box 1, and then the conveyor 32 is briefly closed, and then the multiple baking lamps 27 installed in the installation bin 2 are turned on for heating, and then the multiple fans 26 installed in the installation bin 2 are turned on, and the fans 26 will draw the outside air into the air inlet bin 24, and then enter the installation bin 2, and then be conveyed to the buffer bin 25 through the fans 26, and then be conveyed to the curing box 1 through the buffer bin 25 to dry the surface of the parts in the curing box 1, thereby speeding up the curing efficiency, and then the drying air entering the curing box 1 will enter the connecting bins 28 set on both sides of the curing box 1, and then the drying air entering the corresponding connecting bins 28 will pass through a section of connection The connecting pipe 29 will be re-connected to the air inlet bin 24 and then reused. When the air inside the curing box 1 needs to be replaced, the sealing plate 31 arranged on the outside of the connecting bin 28 will be removed, and then the fan 26 installed in the connecting bin 28 will be opened, so that the fan 26 can speed up the air flow and blow the air in the curing box 1 out of the connecting bin 28 to achieve air discharge. At the same time, fresh air from the outside enters through the air inlet bin 24 to complete the air replacement. After the replacement is completed, the sealing plate 31 can be reinstalled to the outside of the connecting bin 28. During the drying and curing process, the staff can observe the curing progress of the parts at any time through the observation window 33 opened on one side of the curing box 1. After curing is completed, the conveyor 32 is opened again so that the conveyor 32 can convey the parts with the surface coating cured to the next process, and then the next batch of parts can be cured according to the above steps.

[0042] In summary, when the entire device is in use or running: when it is necessary to adjust the delivery speed of the drying air, first rotate the control plate 17 so that the control plate 17 drives the arc groove 18 and the circular groove 19 to move. When the circular groove 19 moves to a position concentric with the round rod 20, push the locking sleeve 14 so that the locking sleeve 14 drives the round rod 20 and the circular plate 21 to pass through the circular groove 19, and make the locking sleeve 14 and the control plate 17 cooperate to squeeze the push spring 23. When the push spring 23 is squeezed to the limit, the corresponding circular plate 21 just passes through the circular groove 19 and reaches the other side of the control plate 17. Then rotate the control plate 17 in the opposite direction so that the control plate 17 drives the arc groove 18 and the circular groove 19 to move. Then the round rod 20 will enter the arc groove 18, and at the same time the locking sleeve 14 will pass through the circular groove 18. The cooperation between the rod 20 and the corresponding circular plate 21 is limited to one side of the control plate 17. At this time, the locking rod 16 loses the limit of the locking sleeve 14, and then the rotating sleeve 5 is rotated. The rotating sleeve 5 will drive the locking rod 16 to move, and then the side wall of the locking groove 15 will squeeze one end of the locking rod 16. Due to the rounded structure at the end of the locking rod 16 and the edge of the locking groove 15, one end of the locking rod 16 will slide out of the locking groove 15, and then the other end of the locking rod 16 will drive the connecting spring 13 to stretch. At the same time, the rotating sleeve 5 will drive the adapter sleeve 12 to rotate through the connecting rod 22. Since the inner side of the adapter sleeve 12 and the adapter rod 11 are both prismatic structures, the adapter sleeve 12 will drive the adapter rod 11 to rotate, and then the adapter rod 11 will simultaneously drive the blocking rods 8 connected at both ends. And the matching rod 7 rotates. Since the matching rod 7 and the matching sleeve 6 are movably connected by a thread, the matching rod 7 will move spirally along the matching sleeve 6, and then the matching rod 7 will drive the adapter rod 11 to slide along the adapter sleeve 12, and then the adapter rod 11 will drive the blocking rod 8 connected at the other end to move in the circulation tube 10, so that the number of the circulation holes 9 opened on the side wall of the circulation tube 10 changes, thereby changing the volume of the drying air passing through, thereby achieving the purpose of adjusting the drying air delivery speed. After the adjustment is appropriate, stop rotating the rotating sleeve 5, and make the connecting spring 13 drive the locking rod 16 to reset, so that the other end of the locking rod 16 is inserted into the corresponding locking groove 15, and then rotate the control plate 17 again, so that the control plate 17 drives the arc again The arc groove 18 and the circular groove 19 rotate. When the circular groove 19 moves to the position corresponding to the circular plate 21, the push spring 23 pushes the locking sleeve 14 to drive the round rod 20 and the circular plate 21 to slide and reset. When the push spring 23 is completely reset, the control plate 17 is rotated again, so that the control plate 17 drives the arc groove 18 and the circular groove 19 to move to a position that does not correspond to the round rod 20 and the circular plate 21, so that the round rod 20 and the circular plate 21 cooperate to limit the locking sleeve 14 to prevent the locking sleeve 14 from sliding, and then the locking sleeve 14 will limit the locking rod 16, and then the locking rod 16 and the locking groove 15 cooperate to limit the rotating sleeve 5 to prevent the rotating sleeve 5 from moving, thereby preventing the adjusted flow rate from changing easily, greatly improving the structural stability.

[0043] When the equipment needs to be used, the parts after powder spraying are first conveyed to the conveyor 32, and then the conveyor 32 is turned on, so that the conveyor 32 drives the parts to move into the curing box 1, and then the conveyor 32 is temporarily closed, and then the multiple baking lamps 27 installed in the installation bin 2 are turned on for heating, and then the multiple fans 26 installed in the installation bin 2 are turned on, and the fans 26 will draw the outside air into the air inlet bin 24, and then enter the installation bin 2, and then be conveyed to the buffer bin 25 through the fan 26, and then be conveyed to the curing box 1 through the buffer bin 25 to dry the surface of the parts in the curing box 1, thereby speeding up the curing efficiency, and then the drying air entering the curing box 1 will enter the connecting bins 28 set on both sides of the curing box 1, and then the drying air entering the corresponding connecting bins 28 will pass through a connected connecting pipe 29 will return to the air intake bin 24 and then be reused. When the air inside the curing box 1 needs to be replaced, the sealing plate 31 set on the outside of the connecting bin 28 will be removed, and then the fan 26 installed in the connecting bin 28 will be turned on to make the fan 26 accelerate the air flow speed and blow the air in the curing box 1 out of the connecting bin 28 to achieve air discharge. At the same time, fresh air from the outside enters through the air intake bin 24 to complete the air replacement. After the replacement is completed, the sealing plate 31 will be reinstalled to the outside of the connecting bin 28.
