Description

Technical Field

[0001] This utility model relates to the field of back panel processing technology, and more specifically, to a powder coating processing device for television back panels. Background Technology

[0002] Powder coating for TV back panels is a process for surface treatment of the TV back panel. Powder coating achieves a smooth, flat surface with high strength, strong corrosion resistance, environmental friendliness, and durability, thus increasing the lifespan of the back panel.

[0003] According to the search, Chinese patent application number 202322167896.X discloses a powder coating processing device for a TV back panel, including a powder coating box, a powder coating box and a dust removal box are arranged in the middle of a moving guide rail, a dust removal frame is fixedly arranged inside the dust removal box, two cleaning rollers are slidably installed inside the dust removal frame, and multiple powder coating heads are arranged at the top inside the powder coating box.

[0004] While the aforementioned patent effectively removes dust and impurities adhering to the outer side of the back panel, it still has the following shortcomings during use: When cleaning dust from the back panel using the cleaning roller, dust is transferred from the back panel to the cleaning roller. Although this process is part of the cleaning operation, the cleaning effect is limited because the dust accumulated on the cleaning roller is difficult to remove in a timely manner. If this accumulated dust is not dealt with promptly, the cleaning roller may release the collected dust back onto the back panel surface during subsequent use, causing secondary pollution. This phenomenon not only reduces cleaning efficiency but may also lead to increased dust adhesion on the back panel, increasing the difficulty of subsequent cleaning and affecting the efficiency of dust removal from the back panel.

[0005] Therefore, there is an urgent need for a powder coating processing device for television back panels to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a powder coating processing device for television back panels, so as to solve the problems mentioned in the background art.

[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0008] A powder coating processing device for a television back panel includes a conveyor frame and a rolling frame fixedly connected to the top wall of the conveyor frame. Two sets of rolling frames are symmetrically arranged about the central axis of the conveyor frame. Fixed plates are slidably connected to the top walls of the two sets of rolling frames. A dust collection box is fixedly connected to the top wall of the conveyor frame. A dust suction plate is rotatably connected to the side wall of the dust collection box. A first gear is fixedly connected to one end of the dust suction plate that passes through the conveyor box. A clamping plate is fixedly connected to the side wall of the conveyor box. A clamping groove is opened on the top wall of the clamping plate. A first rack is slidably connected to the top wall of the clamping plate through the clamping groove. The first rack meshes with the first gear. A driving component is connected to the side wall of the dust collection box. A second rack that cooperates with the driving component is fixedly connected to one end of the fixed plate that passes through the conveyor frame.

[0009] As a preferred technical solution of this application, the driving component includes a mounting plate fixedly connected to the side wall of the dust collector, a crank rotatably connected to the side wall of the mounting plate, a slide fixedly connected to the side wall of the first rack, the output end of the crank being slidably connected to the slide, and a second gear fixedly connected to one end of the crank that passes through the mounting plate, the second rack being meshed with the second gear.

[0010] As a preferred technical solution of this application, a powder spraying box is fixedly connected to the top wall of the conveyor frame, a dust collection box is fixedly connected to the top wall of the powder spraying box, a suction pipe is fixedly connected to the side wall of the dust collection box, two sets of suction pipes are symmetrically arranged about the central axis of the dust collection box, a pump body is fixedly connected to the outer wall of the suction pipe, and the end of the suction pipe away from the dust collection box is also fixedly connected to the suction plate. The dust collection box, the suction pipe and the suction plate are connected in communication.

[0011] As a preferred technical solution of this application, the side wall of the dust collector is provided with an adaptation groove. Two sets of adaptation grooves are symmetrically arranged about the central axis of the dust collector. A slider is slidably connected to the side wall of the adaptation groove. A spring is fixedly connected to the top wall of the slider. A cleaning rod is rotatably connected to the side wall of the two sets of sliders.

[0012] As a preferred technical solution of this application, a clamping plate is slidably connected to the top wall of the fixed plate, and two sets of clamping plates are symmetrically arranged about the central axis of the fixed plate. A third rack is also fixedly connected to one end of the clamping plate that passes through the fixed plate. A third gear is rotatably connected to the bottom wall of the fixed plate. The third rack is meshed with the third gear. A servo motor is fixedly connected to the bottom wall of the fixed plate. The output end of the servo motor is fixedly connected to the third gear. A drive screw is rotatably connected to the bottom wall of the conveyor frame. A drive groove is opened on the top wall of the conveyor frame. One end of the conveyor frame that passes through the drive groove is also threadedly connected to the drive screw.

[0013] In the scheme of this application:

[0014] As the suction plate moves into the dust collection box via the fixed plate, it oscillates back and forth, drawing dust from the TV's back panel into the collection box. This significantly improves dust handling efficiency and practicality, solving the problem in existing technologies where dust transfers from the back panel to the cleaning roller during cleaning. While this is part of the cleaning process, the accumulated dust on the cleaning roller is difficult to remove promptly, limiting its cleaning effectiveness. If this accumulated dust is not addressed in time, the cleaning roller may release the collected dust back onto the back panel surface during subsequent use, causing secondary contamination. This not only reduces cleaning efficiency but may also increase dust adhesion on the back panel, making subsequent cleaning more difficult and impacting the overall efficiency of dust removal.

The second rack 109 is meshed with the second gear 113. The action of the crank 111 and the slide 112 in cooperation facilitates the reciprocating motion of the first rack 108, making it more convenient to use.

[0026] like Figure 1-4 As shown, in a preferred embodiment, based on the above method, a powder spraying box 120 is fixedly connected to the top wall of the conveyor frame 100, a dust collection box 121 is fixedly connected to the top wall of the powder spraying box 120, a suction pipe 122 is fixedly connected to the side wall of the dust collection box 121, two sets of suction pipes 122 are symmetrically arranged about the central axis of the dust collection box 121, a pump body 123 is fixedly connected to the outer wall of the suction pipe 122, and the end of the suction pipe 122 away from the dust collection box 121 is also fixedly connected to the suction plate 104. The dust collection box 121, the suction pipe 122 and the suction plate 104 are connected, and dust can be collected through the dust collection box 121, making it more practical.

[0027] like Figure 1-6 As shown, in a preferred embodiment, based on the above method, the dust collection box 103 is further provided with an adaptation groove 130 on its side wall.

The fixed plate 102 is moved by the action of the drive screw 138, thereby realizing the cleaning of dust on the surface of the back plate and the sandblasting work, which is beneficial to improving work efficiency.

[0029] Specifically, in use, the powder coating processing device for television back panels works as follows: First, the television back panel is placed on the fixing plate 102. Then, the servo motor 137 is started to drive the third gear 136 to rotate. When the third gear 136 rotates, it drives the clamping plate 134 to fix the television back panel through the third racks 135 on both sides. Then, the drive screw 138 is started to move the fixing plate 102. When the television back panel moves into the dust collection box 103, the cleaning rod 133 can better fit with the television back panel under the action of the spring 132. The cleaning rod 133 sweeps up the dust on the surface of the television back panel. Then, the fixing plate 102 drives the second gear... When rack 109 contacts the second gear 113, it drives crank 111 to rotate. Crank 111 slides in slide 112, which drives first rack 108 to slide on top of clamp plate 106. The reciprocating motion of first rack 108 drives first gear 105 to deflect. First gear 105 drives dust suction plate 104 to swing back and forth.
