Description

Technical Field

[0001] This utility model relates to the field of powder coating technology, specifically to an electrostatic powder coating device for corrosion-resistant wrought iron tables and chairs. Background Technology

[0002] Electrostatic powder coating is a commonly used spraying technology. During the spraying process, powder is given an electrostatic charge, allowing it to adhere evenly to the surface of the workpiece, providing excellent corrosion resistance and a beautiful surface finish. Wrought iron tables and chairs also require electrostatic powder coating during production to improve their appearance and durability.

[0003] Currently, when electrostatically powder coating wrought iron tables and chairs is performed, the tables and chairs are hung on a frame, and then a person manually applies the powder coating using a handheld spray gun. After the powder coating is completed, the tables and chairs need to be removed from the frame and transferred to a baking and curing chamber. However, the process of transferring wrought iron tables and chairs from the powder coating site to the baking and curing chamber mainly relies on manual labor. Manual handling is time-consuming, labor-intensive, and physically demanding. In addition, if the tables and chairs are removed and moved manually immediately after the powder coating is completed, the coating on the outer surface can be easily damaged, affecting the quality of the powder coating. Utility Model Content

[0004] The purpose of this invention is to provide a convenient electrostatic powder coating device for transporting corrosion-resistant wrought iron tables and chairs, which effectively solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution.

[0006] An electrostatic powder coating device for corrosion-resistant wrought iron tables and chairs includes a base and a baking oven. The baking oven is arranged on one side of the base. A loading station is provided on the side of the base away from the baking oven, and a unloading station is provided on the side of the base near the baking oven. A powder coating station is provided on the side of the base between the loading station and the unloading station. A powder coating mechanism is provided on the powder coating station. Support frames are fixed on both sides of the upper surface of the base. A crossbar is installed on the top of the two support frames. A conveying mechanism is provided inside the crossbar. Several hooks for hanging tables and chairs are evenly distributed on the conveying mechanism. The conveying mechanism is used to drive the hooks to move along the length of the crossbar.

[0007] Therefore, the horizontal frame and the conveyor mechanism arranged on it can transport tables and chairs in a straight line. During the transport, the tables and chairs pass through the powder coating station. After the powder coating process is completed, the conveyor mechanism can continue to transfer them to the unloading station. Since the baking oven is close to the unloading station, it is convenient to transfer the tables and chairs into the baking oven after they are removed. The conveying effect provided by the conveyor mechanism replaces the traditional long-distance manual transfer, saving time and labor, reducing the workload of workers, and increasing efficiency. Maintaining a certain distance between the powder coating station and the unloading station provides a buffer time for the powder coating on the tables and chairs to cure, avoiding damage to the powder coating caused by immediate unloading and transfer after the tables and chairs are coated, and improving the surface powder coating quality of the tables and chairs.

[0008] Furthermore, the crossbeam has an inner cavity extending along its length, and the lower surface of the crossbeam has a guide groove extending along its length, which communicates with the inner cavity. The conveying mechanism includes a belt, a pair of shafts, a pair of guide wheels, and a drive device. The two shafts are rotatably mounted on both sides of the inner cavity, and the two guide wheels are fixedly sleeved on the two shafts. The belt is sleeved on the two guide wheels. The drive device is arranged on the side of the crossbeam to drive one of the shafts to rotate. Several fixing blocks are arranged at intervals on the surface of the belt along its extension direction, and each hook is installed on the fixing block in a corresponding manner. As the belt rotates, each hook can pass through the guide groove and extend to the bottom of the crossbeam.

[0009] Furthermore, the drive device uses a drive motor, which is fixed on the outer side of the cross frame. The output shaft of the drive motor extends through into the inner cavity and is fixedly connected to the end of one of the shafts.

[0010] Furthermore, each fixing block surface has grooves on both sides of the hook, and each groove has a guide roller rotatably installed in it. The outer edge of the guide roller is in contact with the bottom wall of the inner cavity.

[0011] Furthermore, the powder coating mechanism includes a powder tank, a side frame, a powder pump, an electrostatic spray gun, a first connecting pipe, and a second connecting pipe. The powder tank is arranged on the powder coating station, the side frame is fixed to the side of the powder tank, the powder pump is installed on the side frame, one end of the second connecting pipe is connected to the powder tank, and the other end is connected to the powder pump input section. One end of the first connecting pipe is connected to the electrostatic spray gun, and the other end is connected to the powder pump output section.

[0012] Furthermore, the powder tank has a feeding port on top, which is equipped with a cap. The powder coating station has a vertically extending column, and the top of the column has a rack for placing the electrostatic spray gun.

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

[0014] 1. This utility model utilizes a cross frame and a conveying mechanism arranged on the cross frame to transport tables and chairs along a straight line. During the transport process, the tables and chairs can pass through the powder coating station. After the powder coating process is completed, the conveying mechanism can continue to transfer them to the unloading station. Since the baking oven is close to the unloading station, it is convenient to remove the tables and chairs and transfer them into the baking oven. The conveying effect provided by the conveying mechanism replaces the traditional long-distance manual transfer, saving time and effort, reducing the workload of workers, and is highly efficient.

[0015] 2. In this utility model, a certain distance is maintained between the powder coating station and the unloading station to provide a buffer time for the curing of the powder coating on the tables and chairs, avoiding damage to the powder coating caused by unloading and transferring the materials immediately after the tables and chairs are coated, and improving the powder coating quality of the table and chair surfaces.

[0016] 3. In this invention, when the fixed block moves to below the belt, the hook extends through the guide groove to below the crossbeam. At this time, the outer wall of the guide roller abuts against the bottom wall of the inner cavity. When the fixed block moves, the guide roller rolls, which not only provides guidance for the fixed block and ensures that the fixed block moves more smoothly and stably, but also provides support for the belt, fixed block and hook, ensuring that the belt, fixed block and hook can bear the weight of the table and chair, and improves the stability during conveying, achieving two goals at once.

[0026] Please see Figures 1-5 This utility model provides an electrostatic powder coating device for corrosion-resistant wrought iron tables and chairs, including a base 1 and a baking oven 2. The baking oven 2 is arranged on one side of the base 1. A loading station 11 is provided on the side of the base 1 away from the baking oven 2, and a unloading station 13 is provided on the side of the base 1 near the baking oven 2. A powder coating station 12 is provided on the side of the base 1 between the loading station 11 and the unloading station 13. A powder coating mechanism 4 is provided on the powder coating station 12. Support frames 101 are fixed on both sides of the upper surface of the base 1. A cross frame 3 is installed on the top of the two support frames 101. A conveying mechanism 5 is provided in the cross frame 3. Several hooks 6 for hanging tables and chairs are evenly distributed on the conveying mechanism 5. The conveying mechanism 5 is used to drive the hooks 6 to move along the length of the cross frame 3.

[0027] When using this device to perform powder coating on wrought iron tables and chairs, the finished tables and chairs are hung on hooks 6 at the loading station 11. As the conveying mechanism 5 transports them, the tables and chairs are moved to the powder coating station 12. The powder coating mechanism 4 is used to perform powder coating on the tables and chairs. After the coating is completed, the conveying mechanism 5 continues to transport the tables and chairs to the unloading station 13, where they are unloaded. They are then transferred to the adjacent baking oven 2. After the powder coating on the surface of the tables and chairs is heated and cured, the electrostatic powder coating process on the surface of the wrought iron tables and chairs is achieved. This invention utilizes a crossbeam 3 and a conveyor mechanism 5 arranged on the crossbeam 3 to transport tables and chairs along a straight line. During the transport process, the chairs pass through the powder coating station 12. After the powder coating process is completed, the conveyor mechanism 5 can continue to transfer them to the unloading station 13. Since the baking oven 2 is close to the unloading station 13, it is convenient to transfer the tables and chairs into the baking oven 2 after they are removed. The conveying effect provided by the conveyor mechanism 5 replaces the traditional long-distance manual transfer, saving time and effort, reducing the workload of workers, and increasing efficiency. In addition, a certain distance is maintained between the powder coating station 12 and the unloading station 13, providing a buffer time for the powder coating on the tables and chairs to cure, avoiding damage to the powder coating if the tables and chairs are unloaded and transferred immediately after the coating is applied, and improving the powder coating quality of the table and chair surfaces.

[0028] Specifically, the cross frame 3 has an inner cavity 301 extending along its length, and the lower surface of the cross frame 3 has a guide groove 302 extending along its length. The guide groove 302 communicates with the inner cavity 301. The conveying mechanism 5 includes a belt 53, a pair of shafts 51, a pair of guide wheels 52, and a drive device. The two shafts 51 are rotatably installed on both sides of the inner cavity 301, and the two guide wheels 52 are fixedly sleeved on the two shafts 51. The belt 53 is sleeved on the two guide wheels 52. The drive device is arranged on the side of the cross frame 3 to drive one of the shafts 51 to rotate. Several fixing blocks 61 are arranged at intervals on the surface of the belt 53 in its extending direction. Each hook 6 is installed on the fixing block 61 in a corresponding manner. As the belt 53 rotates, each hook 6 can pass through the guide groove 302 and extend to the bottom of the cross frame 3.

[0029] The drive device uses a drive motor 54, which is fixed on the outer side of the cross frame 3. The output shaft of the drive motor 54 extends through into the inner cavity 301 and is fixedly connected to the end of one of the shafts 51.

[0030] The drive motor 54 operates, and its output shaft drives one of the shafts 51 and the guide wheel 52 to rotate, which in turn drives the belt 53 to rotate, thereby transferring the fixed block 61 and the hook 6 to achieve the effect of conveying the table and chair.

[0031] Specifically, each fixing block 61 has a groove 611 on both sides of the hook 6, and a guide roller 612 is rotatably installed in each groove 611. The outer edge of the guide roller 612 abuts against the bottom wall of the inner cavity 301. When the fixing block 61 moves to below the belt 53, the hook 6 extends through the guide groove 302 to below the crossbeam 3. At this time, the outer wall of the guide roller 612 abuts against the bottom wall of the inner cavity 301. When the fixing block 61 moves, the guide roller 612 rolls, which not only provides guidance for the fixing block 61 and ensures that the fixing block 61 moves more smoothly and stably, but also provides support for the belt 53, fixing block 61 and hook 6, ensuring that the belt 53, fixing block 61 and hook 6 can bear the weight of the table and chair, and improves the stability during transportation, achieving two goals at once.

[0032] Specifically, the powder coating mechanism 4 includes a powder tank 41, a side frame 42, a powder pump 43, an electrostatic spray gun 44, a first connecting pipe 45, and a second connecting pipe 46. The powder tank 41 is arranged on the powder coating station 12, the side frame 42 is fixed to the side of the powder tank 41, the powder pump 43 is installed on the side frame 42, one end of the second connecting pipe 46 is connected to the powder tank 41, and the other end is connected to the input part of the powder pump 43. One end of the first connecting pipe 45 is connected to the electrostatic spray gun 44, and the other end is connected to the output part of the powder pump 43. The powder pump 43 pumps the powder in the powder tank 41 through the second connecting pipe 46 and the first connecting pipe 45 to the electrostatic spray gun 44. The electrostatic spray gun 44 generates an electrostatic field, which carries a negative charge on the powder and sprays it out. The operator holds the electrostatic spray gun 44 and aims it at the table and chair to realize the electrostatic powder coating process of the table and chair.

[0033] Specifically, the powder tank 41 has a feeding port 411 on the top, and a cover 412 is provided on the feeding port 411. The powder tank 41 has a transparent effect, which makes it easy to observe the remaining amount of powder inside. When the remaining powder is insufficient, the cover 412 is opened, and powder can be easily added to the powder tank 41 through the feeding port 411. The powder coating station 12 is provided with a vertically extending column 441. The top of the column 441 is provided with a placement rack 442 for placing the electrostatic spray gun 44. When not in use, the electrostatic spray gun 44 can be placed on the placement rack 442 for storage.
