Description

Technical Field

[0001] This invention relates to the field of steel pipe coating technology, and more particularly to a steel pipe surface coating device. Background Technology

[0002] Existing patent CN216857070U discloses a steel pipe surface coating device for coating steel pipe processing, including a coating box. A movable plate is movably connected to one side of the coating box via a drive structure. A paint storage box is connected to one side wall of the movable plate. An inlet is connected to the top of the paint storage box. A pump is installed at the bottom of the paint storage box, and a connecting pipe is connected to the outlet of the pump. This invention, comprising a coating box, movable plate, drive structure, paint storage box, pump, fixed plate, high-voltage electrostatic spray gun, connecting pipe, rotating structure, coating box door, controller, and transparent observation window, enables automated one-time uniform coating of the inner and outer surfaces of steel pipes. It eliminates the need for personnel to participate in the coating process, reducing the coating intensity and accelerating the coating efficiency of the steel pipes. However, in the aforementioned prior art, because the high-voltage electrostatic spray gun and the fixed plate are fixedly connected, the entire paint storage box must be disassembled when the high-voltage electrostatic spray gun is maintained or repaired. This disassembly process is time-consuming and labor-intensive, making it inconvenient for maintaining or repairing the high-voltage electrostatic spray gun.

[0003] By making the high-voltage electrostatic spray gun and the mounting plate detachable, the time-consuming and laborious disassembly process during maintenance and repair is effectively avoided.

[0004] However, in the aforementioned prior art, workers need to disassemble the high-voltage electrostatic spray gun through the coating box door. Since the coating box door is far from the high-voltage electrostatic spray gun, workers need to extend both arms into the coating box to disassemble the high-voltage electrostatic spray gun. Summary of the Invention

[0005] The purpose of this invention is to provide a steel pipe surface coating device, which solves the technical problem in the prior art where workers need to disassemble the high-voltage electrostatic spray gun through the coating box door. Because the coating box door is far from the high-voltage electrostatic spray gun, workers need to extend their entire arms into the coating box to disassemble the high-voltage electrostatic spray gun.

[0006] To achieve the above objectives, the present invention provides a steel pipe surface coating device, comprising a coating box door, an assembly unit, a paint storage box, a drive unit, a coating box, and a side door mechanism. The paint storage box is equipped with two fixing plates, and a high-voltage electrostatic spray gun is mounted on each fixing plate and connected to the paint storage box. The coating box door is hinged to the coating box and located at one end of the coating box. The assembly unit is fixedly connected to the coating box and located inside the coating box door. The paint storage box is slidably connected to the coating box and located at the other end of the coating box. The drive unit is fixedly connected to the coating box and located at the side door mechanism. The side door mechanism includes two fixing blocks, two snap-fit ​​components, and a side door. One side of the coating box has a through hole. The two fixing blocks are fixedly connected to the coating box and symmetrically arranged on both sides of the through hole. The two snap-fit ​​components are fixedly connected to the coating box and symmetrically arranged above the through hole. The lower part of the side door is hinged to the corresponding fixing block and located between the two fixing blocks. The side door is also slidably connected to the coating box and located within the through hole. The upper part of the side door is snapped into the corresponding snap-fit ​​component and located between the two snap-fit ​​components.

[0007] The side door mechanism also includes a handle, which is fixedly connected to the side door and located on the end face of the side door.

[0008] The side door includes a rotating rod and a door body. The rotating rod is fixedly connected to the door body and is located below the door body. The rotating rod is also hinged to the corresponding fixing block and passes through the two fixing blocks. The door body is slidably connected to the coating box. The top of the door body is snapped into the corresponding snap-fit ​​assembly. The handle is fixedly connected to the door body.

[0009] The snap-fit ​​assembly includes a snap-fit ​​body and a storage block. The snap-fit ​​body is slidably connected to the storage body and extends through the interior of the storage body. The snap-fit ​​body is also snap-fitted to the door. The storage block is fixedly connected to the coating box.

[0010] The steel pipe surface coating device also includes a controller, which is fixedly connected to the coating box door and located on the end face of the coating box door.

[0011] This invention discloses a steel pipe surface coating device. By pulling the two locking components to separate from the side door, and then pulling the side door, the side door moves outward under the support of the two fixing blocks. When the side door and the through hole are pulled out, the side door is rotated along the two fixing blocks to fit against the coating box body. The operator can then disassemble the components on the fixing plate. This method effectively solves the technical problem that the operator needs to reach into the coating box body to disassemble the high-voltage electrostatic spray gun through the coating box door, which is far from the high-voltage electrostatic spray gun, in order to disassemble the high-voltage electrostatic spray gun.

[0029] In this specific embodiment, the paint storage box 112 is provided with two fixing plates 111, and a high-voltage electrostatic spray gun 110 is provided on the fixing plates 111. The high-voltage electrostatic spray gun 110 is connected to the paint storage box 112. The coating box door 103 is hinged to the coating box 104 and located at one end of the coating box 104. The assembly unit 113 is fixedly connected to the coating box 104 and located inside the coating box door 103. The paint storage box 112 is slidably connected to the coating box 104 and located at the... At the other end of the coating box 104, the drive unit 109 is fixedly connected to the coating box 104 and located on one side of the paint storage box 112. The drive unit 109 is also connected to the paint storage box 112 in a transmission manner. The coating box door 103 can prevent the epoxy powder particles inside the steel pipe surface coating device from flying out when it is working. The assembly unit 113 can coat the steel pipe. The paint storage box 112 can store the coating material. The drive unit 109 can drive the paint storage box 112 to move.

[0030] The coating box 104 has a through hole on one side. Two fixing blocks 108 are fixedly connected to the coating box 104 and symmetrically arranged on both sides of the through hole. Two snap-fit ​​components are fixedly connected to the coating box 104 and symmetrically arranged above the through hole. The side door 102 is hinged to the corresponding fixing block 108 at the bottom and located between the two fixing blocks 108. The side door 102 is slidably connected to the coating box 104 and located inside the through hole.

[0034] When using the steel pipe surface coating device of this embodiment, to disassemble the components on the fixing plate 111, the two snap-fit ​​components are pulled to separate from the side door 102, and then the side door 102 is pulled. The side door 102 moves outward under the support of the two fixing blocks 108. When the side door 102 is pulled out of the through hole, the side door 102 is rotated along the two fixing blocks 108 to fit against the coating box 104. The operator can then disassemble the components on the fixing plate 111. This method effectively solves the technical problem that the operator needs to disassemble the high-voltage electrostatic spray gun 110 through the coating box door 103. Since the coating box door 103 is far from the high-voltage electrostatic spray gun 110, the operator has to put both arms into the coating box 104 to disassemble the high-voltage electrostatic spray gun 110.
