Description
Technical Field
[0001] This utility model relates to the field of spraying equipment technology, and in particular discloses a spraying device and a fully automatic intelligent spraying line with the spraying device. Background Technology
[0002] With the rapid development of modern industry, spraying technology has been widely used in various manufacturing fields, especially in the automotive, home appliance, and building materials industries, where spraying processes play a vital role in improving product appearance quality and protective performance. However, traditional spraying equipment has many shortcomings, particularly in terms of production efficiency, paint utilization rate, and environmental performance.
[0003] Existing spraying equipment typically only sprays one side of a workpiece, requiring multiple flips or conveyors to complete the coating of the entire surface. This not only increases production time but also raises the complexity of manual operation. Secondly, paint waste is significant during the spraying process; excess paint that is not effectively recycled can cause environmental pollution and increase production costs. Furthermore, spraying quality is difficult to control, easily resulting in uneven coating thickness and insufficient paint adhesion, thus affecting the quality of the final product. Utility Model Content
[0004] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide a spraying equipment that can recycle excess paint during the spraying process, thereby reducing waste and pollution and improving spraying efficiency.
[0005] To achieve the above objectives, this utility model provides a spraying device, including a conveying device, a spraying device, and a control device. The conveying device passes through the spraying device and is used to transport the workpiece. The control device is electrically connected to and controls the operation of the conveying device and the spraying device. The spraying device includes a spray booth, a spraying mechanism, and a recovery mechanism. The recovery mechanism and the spraying mechanism are housed within the spray booth. The conveying device passes through the spray booth. The spraying mechanism is used to spray paint onto the workpiece, and the recovery mechanism is used to recover excess paint sprayed by the spraying mechanism. This utility model performs spraying operations on the workpiece through the spraying mechanism, while the recovery mechanism recovers excess paint during the spraying process, thereby reducing waste and pollution. This design effectively integrates the functions of conveying, spraying, and recovery, making the entire spraying process more efficient and environmentally friendly.
[0006] Furthermore, the recycling mechanism includes an exhaust motor, an exhaust pipe, and a collection box. The exhaust motor drives the exhaust pipe to extract residual paint from the spray booth and collect it into the collection box. By using the exhaust motor to drive the exhaust pipe, the recycling mechanism extracts excess paint remaining in the spray booth into the collection box for further processing or reuse. This recycling system reduces paint waste during the spraying process and lowers pollution levels in the spray booth, thereby improving the environmental performance of the spraying process.
[0007] Furthermore, the spraying mechanism includes a lifting frame, a spray gun located at the output end of the lifting frame, and an infrared sensor mounted on the lifting frame. The lifting frame includes a drive cylinder and a mounting plate connected to the drive cylinder. The spray gun is mounted on the mounting plate. The spraying mechanism, comprising a lifting frame, a spray gun, and an infrared sensor, controls the position of the spray gun via the drive cylinder. The infrared sensor detects the presence of the workpiece to precisely control the spraying process. This design enables precise control of the spray gun's movement and spraying time, improving spraying quality and reducing paint waste.
[0008] Furthermore, the spraying mechanism is provided in multiple sets, located inside the spray booth and on both sides of the conveying device. These multiple sets of spraying mechanisms spray the front and back sides of the workpiece respectively. This design improves spraying efficiency and reduces the time and steps required for workpieces to be flipped or sprayed multiple times.
[0009] Furthermore, the spraying device also includes a touch-up paint area for supplementing the coating on workpieces that have already been sprayed by the spraying mechanism. The touch-up paint area in the spraying device is specifically designed to supplement the coating on workpieces that have already been sprayed but may have missing paint. This function ensures uniform paint coverage on the workpiece surface and improves the quality of the final product.
[0010] Furthermore, the spraying mechanism also includes an electrostatic generator mounted on the spray gun. The electrostatic generator is used to imbue the paint sprayed from the spray gun with static electricity. The electrostatic generator in the spraying mechanism causes the paint sprayed from the spray gun to become statically charged, increasing the adhesion between the paint and the workpiece surface. Electrostatic spraying technology improves paint utilization, reduces overspraying, and enhances spraying quality.
[0011] Furthermore, the mounting plate is equipped with a clamping and fixing assembly, which includes a sliding screw mounted on the mounting plate, a slider adapted to the sliding screw, and a connecting rod connected to the slider. The two ends of the connecting rod are respectively rotatably connected to the slider and the spray gun. The clamping and fixing assembly on the mounting plate controls the fixing and adjustment position of the spray gun through the sliding screw, slider, and connecting rod to ensure spraying accuracy. This design provides stable and precise spray gun fixing and position adjustment, further improving the accuracy and efficiency of spraying.
[0012] This utility model also provides a fully automatic intelligent spraying line with a spraying device, including a spraying device for spraying workpieces, an loading section, an unloading section, a transfer device, a curing oven for melting and curing the coating on the workpiece, and a cooling section for cooling the coating. The transfer device is sequentially connected to the loading section, the spraying device, the curing oven, the cooling section, and the unloading section. This design provides stable and precise spray gun fixing and position adjustment, further improving the accuracy and efficiency of spraying.
[0013] Furthermore, the curing oven includes an oven body and a heating furnace disposed inside the oven body. The heating furnace includes a hollow heating chamber, a burner for heating air, and a fan for transmitting the air heated by the burner to the oven body. The burner and fan are respectively located at both ends of the heating chamber and connected to the heating chamber. A return air vent is provided on the heating chamber, connecting the heating chamber and the oven body. By providing a return air vent next to the burner, the cold air from the oven body is blown from the return air vent to the burner for heating under the suction of the fan, and then blown back into the oven body by the fan to complete the circulation. This keeps the air in the oven body stable and uniform, reduces heat loss, and increases the efficiency of heat exchange.
[0014] Furthermore, the furnace body wall includes a support plate, with an insulation layer on the outside of the support plate. The insulation layer includes double-layer fiberglass board and double-layer rock wool insulation board, and an outer panel is provided on the outside of the insulation layer. The outer panel is fixed with corner trim around its perimeter. The support plate is used to fix the furnace body and install the insulation layer. The double-layer fiberglass board and double-layer rock wool insulation board can prevent heat loss inside the furnace, ensure a uniform temperature inside the furnace, and increase the efficiency of heat exchange. At the same time, the multi-layer insulation structure can effectively reduce noise. The outer panel protects the insulation layer from damage, making the furnace body aesthetically pleasing, sturdy, and durable.
[0015] The beneficial effects of this utility model are as follows: This utility model uses a spraying mechanism to spray the workpiece, while a recycling mechanism recovers the excess paint during the spraying process. The recycling mechanism uses a blower motor to drive the exhaust pipe to extract the excess paint remaining in the spray booth into a collection box for further processing or reuse. This recycling system reduces paint waste during the spraying process and reduces pollution in the spray booth, thereby improving the environmental performance of the spraying process.
[0016] The spraying mechanism includes a lifting frame, a spray gun, and an infrared sensor. The lifting frame controls the position of the spray gun through a drive cylinder, and the infrared sensor detects the presence of the workpiece to precisely control the spraying process. This design can accurately control the movement of the spray gun and the spraying time, improving the spraying quality and reducing paint waste. Attached Figure Description

This design can precisely control the movement of the spray gun 10 and the spraying time, improving the spraying quality and reducing paint waste.
[0028] The spraying mechanism 4 is provided in multiple sets, which are located inside the spray booth 3 and on both sides of the conveying device 1. The multiple sets of spraying mechanisms 4 spray the front and back sides of the workpiece respectively. This design improves spraying efficiency and reduces the time and steps required for workpieces to be flipped or sprayed multiple times.
[0029] The spraying device 2 also includes a touch-up paint area 13, which is used to supplement the paint on the workpiece after it has been sprayed by the spraying mechanism 4. The touch-up paint area 13 in the spraying device 2 is specifically designed to supplement the paint on workpieces that have already been sprayed but may have missing paint. This function ensures that the paint coverage on the workpiece surface is uniform and improves the quality of the final product.
[0030] The spraying mechanism 4 also includes an electrostatic generator 14 mounted on the spray gun 10.

This design provides stable and precise fixing and position adjustment of the spray gun 10, further improving the accuracy and efficiency of spraying.
[0032] This utility model also provides a fully automatic intelligent spraying line with a spraying device, including a spraying device for spraying workpieces, an upper section 18, an lower section 19, a transfer device 20, a curing oven 21 for melting and curing the coating on the workpiece, and a cooling section 22 for cooling the coating. The transfer device 20 is sequentially connected to the upper section 18, the spraying device 20, the curing oven 21, the cooling section 22, and the lower section 19. This design provides stable and precise fixing and position adjustment of the spray gun 10, further improving the accuracy and efficiency of spraying.
[0033] The curing oven 21 includes an oven body 23 and a heating furnace 24 disposed inside the oven body 23. The heating furnace 24 includes a hollow heating chamber 25, a burner 26 for heating air, and a fan 29 for transmitting the air heated by the burner 26 to the oven body 23. The burner 26 and the fan 29 are respectively located at both ends of the heating chamber 25 and connected to the heating chamber 25. A return air vent is provided on the heating chamber 25, which connects the heating chamber 25 and the oven body 23. By providing a return air vent next to the burner 26, the cold air from the oven body 23 is blown from the return air vent to the burner 26 for heating under the suction of the fan 29, and then blown back into the oven body 23 by the fan 29 to complete the circulation. This keeps the air in the oven body 23 stable and uniform, reduces heat loss, and increases the efficiency of heat exchange.
[0034] The furnace body 23 includes a support plate 27, and an insulation layer 28 is provided on the outside of the support plate 27. The insulation layer 28 includes double-layer fiberglass board and double-layer rock wool insulation board, and an outer panel is provided on the outside of the insulation layer 28.

At the same time, the multi-layer insulation layer 28 structure can effectively reduce noise. The outer panel protects the insulation layer 28 from damage, making the furnace body 23 aesthetically pleasing, sturdy and durable.
[0035] In this embodiment, the workpiece is loaded onto the transfer device 20 in the loading section 18. The transfer device 20 sends the workpiece into the spraying equipment for spraying according to a predetermined program. The workpiece enters the spray booth 3 through the conveyor device 1. After the workpiece enters the spray booth 3, the infrared sensor detects the position of the workpiece, and the spraying mechanism 4 is activated. Multiple sets of spray guns 10 spray paint on the front and back sides of the workpiece respectively. The movement and spraying speed of the spray guns 10 are automatically adjusted by the control device according to the size and shape of the workpiece to ensure a uniform coating thickness. The electrostatic generator 14 charges the paint sprayed by the spray guns 10 with static electricity, so that the paint adheres better to the surface of the workpiece, reducing overspray and paint waste. If there are parts of the workpiece that need to be repainted, they will enter the touch-up paint area 13 for additional spraying operations. During the spraying process, excess paint in the spray booth 3 that does not adhere to the workpiece is extracted by the recovery mechanism 5 through the exhaust motor 6 and exhaust pipe 7 and collected in the collection box 8 for further processing or recycling.
[0036] After spraying is completed, the workpiece continues to be conveyed to the curing oven 21 via the conveyor 1. The curing oven 21 is equipped with a burner 26 and a fan 29. The burner 26 heats the air, and the fan 29 transmits the hot air to the heating chamber 25. The workpiece is uniformly heated in the heating chamber 25, causing the coating to melt and solidify on the workpiece surface. The return air vent connects the heating chamber 25 and the interior of the oven body 23, realizing the circulation of hot air and ensuring temperature stability and energy efficiency during the curing process. After curing, the workpiece enters the cooling section 22 via the transfer device 20. In the cooling section 22, the coating on the workpiece surface gradually cools to room temperature, achieving the purpose of curing and shaping. After cooling, the workpiece is sent to the next section 19 and unloaded to the designated position, completing the entire process flow of the spraying line.
