Description

Technical Field

[0001] This utility model application relates to the field of spraying device technology, specifically a high-temperature powder spraying device. Background Technology

[0002] High-temperature spraying is a surface treatment method that uses a high-speed airflow to atomize molten spraying material and spray it onto the surface of cleaned and roughened parts to form a coating layer. It is widely used in various fields that require high temperature and corrosion resistance, such as barbecue grills, slow cookers, heaters, heating pipes, mufflers, ovens, vehicle exhaust pipes, chimneys, and other equipment.

[0003] In current high-temperature spraying processes, parts are transported to the high-temperature spraying chamber via a high-temperature resistant conveyor. During the spraying process, powder can easily fall onto the conveyor belt. After prolonged spraying, powder can accumulate on the surface of the conveyor belt. If not cleaned in time, the powder will be difficult to remove once it dries completely, affecting the placement of subsequent parts and also impacting the spraying effect. Summary of the Invention

[0004] To address the problem of excess powder residue remaining on the conveyor belt after drying in existing high-temperature powder coating devices, this invention provides a high-temperature powder coating device to solve the aforementioned problem.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A high-temperature powder coating device includes a conveyor frame, a drive motor on one side of the conveyor frame, a high-temperature coating box near the top of the conveyor frame close to the drive motor, a conveyor belt inside the conveyor frame, the drive motor driving the conveyor belt to move, two water spray pipes rotatably connected below the conveyor belt, each water spray pipe having several spray nozzles on its outer side, one end of each of the two water spray pipes being rotatably connected and communicating with a water distribution pipe, the end of the water distribution pipe away from the water spray pipes being connected to a water pipe, and a recycling box slidably connected to the lower part of the conveyor frame.

[0007] Furthermore, two baffles are symmetrically fixed below the conveyor belt, and several heating tubes are provided at the bottom of the two baffles. The heating tubes are fixedly connected to the inner wall of the conveyor frame, and a fan is provided below the baffles.

[0008] Furthermore, a servo motor is fixed on the side of the transmission frame away from the water distribution pipe, and a pulley is fixed on the output end of the servo motor. Another pulley is provided on the side of the transmission frame. The two pulleys are connected by a transmission belt, and each pulley is fixedly connected to one end of the spray pipe.

[0009] Furthermore, a filter screen is installed inside the recycling bin, and the filter screen is detachably placed inside the recycling bin.

[0010] Furthermore, each of the spray nozzles is tilted toward the other spray pipe, and the spray nozzles on the two spray pipes are oriented opposite each other.

[0011] Furthermore, ventilation openings that mate with the positions of the baffles are respectively provided on both sides of the transmission frame, and the ventilation openings are located below the drive motor.

[0012] Furthermore, the top surface of the fan is provided with an air outlet, and the air outlet is in contact with the heating pipe. Both ends of the high-temperature spraying box are slidably fitted with heat insulation door panels. Each heat insulation door panel has a servo cylinder symmetrically arranged on the top surface of the high-temperature spraying box. The output ends of the two servo cylinders slide through the high-temperature spraying box and are fixed to the top surface of the heat insulation door panel.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this utility model, by setting two water spray pipes below the conveyor belt, and then allowing water to flow into the two water spray pipes through a water distribution pipe, and spraying the water inside the water spray pipes onto the conveyor belt through the water spray nozzles, and at the same time setting a recycling box below the water spray pipes, the problem of excess powder residue on the conveyor belt after drying and the inconvenience of cleaning is solved in the existing high-temperature powder coating device, thus avoiding the residual powder from affecting the subsequent powder coating effect.

[0015] 2. In this utility model, a baffle is set at the bottom of the conveyor belt, and several heating tubes are set inside the bottom of the baffle. The fan blows air into the baffle and heats the air through the heating tubes. After the conveyor belt is washed by the water spray pipe, it is dried by the hot air. At the same time, the hot air is discharged to both sides through the ventilation port, so that the surface of the conveyor belt is kept dry and water stains are avoided so that powder residue will adhere to the conveyor belt.

[0023] Reference Figures 1 to 4 A high-temperature powder coating device includes a transmission frame 1, a drive motor 3 on one side of the transmission frame 1, a high-temperature spraying box 16 on the top of the transmission frame 1 near the drive motor 3, a conveyor belt 2 inside the transmission frame 1, the drive motor 3 drives the conveyor belt 2 to move, two water spray pipes 4 are rotatably connected below the conveyor belt 2, each water spray pipe 4 has several water spray nozzles 5 on its outer side, one end of each of the two water spray pipes 4 is rotatably connected to and communicates with a water distribution pipe 9, the end of the water distribution pipe 9 away from the water spray pipes 4 is connected to a water pipe, and a recycling box 10 is provided below the two water spray pipes 4, the recycling box 10 is slidably connected to the lower part of the transmission frame 1, so that the water spray nozzles 5 clean the conveyor belt 2.

[0024] Specifically, a servo motor 8 is fixed on the side of the transmission frame 1 away from the water distribution pipe 9, and a pulley 6 is fixed on the output end of the servo motor 8. Another pulley 6 is provided on the side of the transmission frame 1. The two pulleys 6 are connected by a transmission belt 7. Each pulley 6 is fixedly connected to one end of the spray pipe 4. A filter screen 11 is provided inside the recycling bin 10. The filter screen 11 is detachably placed inside the recycling bin 10. Each spray nozzle 5 is tilted towards the other spray pipe 4. The spray nozzles 5 on the two spray pipes 4 are oriented in opposite directions, which improves the cleaning efficiency of the spray nozzles 5.

[0025] As an optimization solution, two baffles 12 are symmetrically fixed below the conveyor belt 2. Several heating tubes 13 are provided at the bottom of the two baffles 12. The heating tubes 13 are fixedly connected to the inner wall of the transmission frame 1. A fan 15 is provided below the baffles 12 so that the heating tubes 13 dry the conveyor belt 2.

[0026] Specifically, the top surface of the fan 15 is provided with an air outlet, which is in contact with the heating pipe 13. The two sides of the transmission frame 1 are respectively provided with ventilation openings 14 that match the position of the baffle 12. The ventilation openings 14 are located below the drive motor 3, so that the heat accumulated inside the baffle 12 can be dissipated. Both ends of the high temperature spraying box 16 are slidably fitted with heat insulation door panels 18. The top surface of the high temperature spraying box 16 at the top of each heat insulation door panel 18 is symmetrically provided with servo cylinders 17. The output ends of the two servo cylinders 17 slide through the high temperature spraying box 16 and are fixed to the top surface of the heat insulation door panel 18.

[0027] Working principle: During spraying, the drive motor 3 moves the conveyor belt 2, bringing the parts into the high-temperature spraying chamber 16. Before entering, the servo cylinder 17 moves, causing the insulation door panel 18 to move upward. After the parts enter, the servo cylinder 17 pushes the insulation door panel 18 downward. After spraying is completed, both insulation door panels 18 move upward and open simultaneously, allowing the parts at the feeding end to enter. By connecting the water pipe to the water distribution pipe 9, water flows through the water distribution pipe 9 into the two spray pipes 4 and is sprayed onto the conveyor belt 2 through the spray nozzles 5, cleaning the conveyor belt 2. At the same time, the servo motor 17 is activated. The servo motor 8 drives the two pulleys 6 to rotate, which in turn drives the two water spray pipes 4 to rotate. This causes the angle of the water sprayed from the nozzles 5 to change, thereby improving the cleaning efficiency of the water spray pipes 4 on the conveyor belt 2. The cleaned wastewater falls into the recycling bin 10. At the same time, the filter screen 11 filters the impurities in the wastewater. Meanwhile, the blower 15 is started, causing the blower 15 to blow air towards the heating pipe 13. The heating pipe 13 heats the airflow, thereby drying the conveyor belt 2 with hot air. The hot air is then discharged through the vent 14.
