Description

Technical Field

[0002] Low-temperature curing of coatings refers to a technology that promotes rapid curing of coatings in a relatively low-temperature environment. It is mainly used in coating scenarios that require energy saving or are sensitive to temperature. This type of technology is widely used in automotive refinish paints, wood coatings, electronic component packaging, and other fields, helping factories reduce baking energy consumption while minimizing high-temperature damage to the substrate.

[0004] While the aforementioned patent documents can assist in efficient air intake isolation during implementation, they cannot adjust the curing temperature, which can easily affect the curing quality of the workpiece if the temperature is too high or too low. Utility Model Content

A ventilation pipe is installed at the rear end of the outer surface of the working chamber 8, which can promptly exhaust the hot air inside the working chamber 8 to the outside. The guide mechanism 6 is rotatably connected to the lower part of the working chamber 8. A hot air blower 9 is fixedly installed at the middle of the upper part of the outer surface of the working chamber 8. Cooling components 10 are symmetrically fixedly connected to the upper left and right ends of the outer surface of the working chamber 8, which can regulate the temperature inside the working chamber 8. Exhaust components 11 are symmetrically fixedly connected to the left and right walls of the inner cavity of the working chamber 8, which can evenly discharge the low-temperature air regulated by the two cooling components 10 into the inner cavity of the working chamber 8. A temperature sensor 12 is fixedly installed at the middle of the rear wall of the inner cavity of the working chamber 8. An integrated LED UV lamp group 13 is fixedly installed at the middle of the top wall of the inner cavity of the working chamber 8. A chamber door 14 is rotatably connected to the left front end of the outer surface of the working chamber 8.

[0025] To achieve the purpose of bearing load and protecting the drive mechanism 4 and the driven mechanism 5, refer to... Figure 2 The protective component 3 includes a protective frame 31. The front and rear ends of the outer surface of the protective frame 31 are provided with a number of heat dissipation holes 32 that communicate with the outside, which can dissipate the heat generated by the stepper motor 41 during operation to the outside.

[0026] To achieve the purpose of driving the driven mechanism 5 to rotate, refer to... Figure 3 The drive mechanism 4 includes a stepper motor 41, and a drive gear 42 is fixedly connected to the upper output end of the stepper motor 41, which can drive the transmission gear 52 to rotate.

[0027] To achieve the goal of driving the guide mechanism 6 and the load-bearing mechanism 7 to rotate at a uniform speed, refer to... Figure 3The driven mechanism 5 includes a rotating column 51. A transmission gear 52 is fixedly connected to the upper part of the outer surface of the rotating column 51. It can drive the rotating disk 61 to rotate after meshing with the driving gear 42. The outer surface of the transmission gear 52 is meshed with the outer surface of the driving gear 42. The lower end of the rotating column 51 is rotatably connected to the middle part of the bottom wall of the inner cavity of the protective frame 31.

[0028] To guide and limit the rotation of the bearing mechanism 7, please refer to... Figure 3 The guide mechanism 6 includes a rotating disk 61, with a limiting ring 62 fixedly connected to the middle of the outer surface sidewall of the rotating disk 61, which can guide and limit the rotation of the rotating disk 61. The lower middle of the outer surface of the rotating disk 61 is fixedly connected to the upper end of the rotating column 51.

[0029] To achieve the purpose of bearing load on the workpiece, refer to... Figure 3 The bearing mechanism 7 includes a bearing seat 71. The outer surface of the bearing seat 71 has a number of ventilation holes 72 arranged in a ring array on the side wall. This allows the air inside the working chamber 8 to enter the inner cavity of the bearing seat 71 smoothly and come into contact with the surface of the workpiece. The lower end of the outer surface of the bearing seat 71 is fixedly connected to the upper end of the outer surface of the rotating disk 61.

[0030] To achieve the goal of regulating the temperature inside the working chamber 8, please refer to... Figure 4 The refrigeration assembly 10 includes an air supply duct 101, a refrigeration unit 102 is fixedly connected to the lower end of the outer surface of the air supply duct 101, an exhaust duct 103 is fixedly connected to the lower output end of the refrigeration unit 102, and the upper input end of the outer surface of the air supply duct 101 is fixedly connected to the output end of the hot air blower 9.

[0031] When the hot air discharged from the hot air blower 9 enters the inner cavity of the two air supply pipes 101 and is transported to the inner cavity of the refrigeration unit 102, the temperature of the hot air is adjusted to the required value by the two refrigeration units 102, and then transported to the inner cavity of the corresponding air storage casing 111 through the two exhaust pipes 103, and finally evenly discharged into the inner cavity of the working chamber 8 through several exhaust ports 112.

[0032] To achieve the goal of evenly discharging the regulated low-temperature air from the two refrigeration components 10 into the inner cavity of the working chamber 8, refer to... Figure 4 The exhaust assembly 11 includes an air storage shell 111. Several exhaust ports 112 are spaced apart on the right end of the outer surface of the air storage shell 111, which can make the air inside the air storage shell 111 evenly discharged into the working chamber 8. The left input end of the air storage shell 111 is fixedly connected to the lower output end of the corresponding exhaust pipe 103.

[0033] It should be noted that in this utility model, the hot air blower 9 is model HAM-G3A-11, the temperature sensor 12 is model MKD090B-058-KO1-KN, the integrated LED UV lamp group 13 is model Yuanming UVLED purple light COB module, the stepper motor 41 is model 42BYGHW609, and the refrigerator 102 is model CVHH1550. The specific installation methods, oil circuit connection methods, circuit connection methods, and control methods of the hot air blower 9, temperature sensor 12, integrated LED UV lamp group 13, stepper motor 41, and refrigerator 102 are all conventional designs, and this utility model will not describe them in detail.

[0034] The working principle of this utility model is as follows: First, the workpiece to be cured at low temperature is placed in the inner cavity of the support seat 71 and the chamber door 14 is closed. Then, the power supply of the hot air blower 9 and the two cooling units 102 is turned on, so that the hot air discharged from both ends of the hot air blower 9 is cooled by the corresponding cooling units 102 and then discharged into the inner cavity of the air storage sleeve 111 through the corresponding exhaust pipes 103. The air entering the inner cavity of the two air storage sleeves 111 will be evenly discharged into the inner cavity of the working chamber 8 through several exhaust ports 112. During this period, the temperature of the inner cavity of the working chamber 8 can be detected in real time by the temperature sensor 12. When it is necessary to adjust the temperature of the inner cavity of the working chamber 8, the temperature sensor 12 can be used to detect the temperature of the inner cavity of the working chamber 8. When the temperature decreases, the cooling levels of the two refrigeration units 102 are adjusted to cool the hot air discharged from the hot air blower 9 until the temperature inside the working chamber 8 reaches the required value. At the same time, the stepper motor 41 is driven to rotate the drive gear 42, causing the transmission gear 52 to mesh with the drive gear 42. This causes the rotating column 51 to drive the rotating disk 61 and the limiting ring 62 to rotate at a constant speed. At this time, the workpiece placed inside the bearing seat 71 will rotate at a constant speed inside the working chamber 8, thus ensuring that the workpiece is in uniform contact with the air inside the working chamber 8.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
