Figure 4 It is a schematic structural diagram of a spraying component according to the first embodiment of the present utility model. Figure 5 It is a schematic structural diagram of a mounting plate, a spray head and a mounting cotton according to the first embodiment of the present utility model.

[0024] The utility model provides an anti-corrosion primer roller coating mechanism, which comprises a conveyor belt 101, a lifting motor 102, a support plate 103, a paint box 104, a coating roller 105, a spraying assembly and a collecting mechanism. The collecting mechanism comprises a driving assembly, a sponge cylinder 106, a connecting frame 107, a collecting box 108, a scraping plate 109, a water pump 110 and a return pipe 111. The spraying assembly comprises a mounting plate 112, a spray head 113 and a mounting cotton 114. The driving assembly comprises a hanging plate 115, a mating plate 116, a motor 117 and a rotating shaft 118. Through the above structure, during the painting process of parts, excess paint will drip onto the conveyor belt 101, causing waste of paint, increasing production costs and being inconvenient to clean up.

[0025] For the specific implementation manner, the lifting motor 102 is arranged above the conveyor belt 101. The support plate 103 is fixedly connected to the output end of the lifting motor 102. The paint box 104 is arranged above the support plate 103. The conveyor belt 101 is used for conveying parts. Since the support plate 103 is fixedly connected to the output end of the lifting motor 102, when the lifting motor 102 operates, it drives the support plate 103 to move in the vertical direction, facilitating the adjustment of the height of the paint box. The coating roller 105 is used for roller coating the primer on the parts.

[0026] Among them, the driving component is arranged below the support plate 103, the coating roller 105 is rotatably connected to the driving component, the sponge cylinder 106 is sleeved on the outer side wall of the coating roller 105, the connecting frame 107 is fixedly connected to the support plate 103 and is located below the support plate 103, the collection box 108 is fixedly connected to the connecting frame 107 and is located below the connecting frame 107, the scraping plate 109 is fixedly connected to the collection box 108 and is located on one side of the collection box 108 close to the coating roller 105, the water pump 110 is fixedly connected to the collection box 108 and is located on the outer side wall of the collection box 108, the return pipe 111 is communicated between the water pump 110 and the paint tank 104. The driving component is used to drive the coating roller 105 to rotate, so as to realize the primer roller coating of the parts by the coating roller 105. The sponge cylinder 106 arranged on the outer side wall of the coating roller 105 is used to absorb the primer. The connecting frame 107 is used to support the collection box 108. The paint in the paint tank 104 drops onto the sponge cylinder 106 and is absorbed by the sponge cylinder 106. When the driving component drives the coating roller 105 to rotate, the sponge cylinder 106 rotates with the coating roller 105. Since the scraping plate 109 is in contact with the sponge cylinder 106, the scraping plate 109 scrapes the rotating sponge cylinder 106 to remove the excess paint on the sponge cylinder 106, avoiding the waste of raw materials caused by the paint remaining in the sponge cylinder 106. At the same time, the paint scraped by the scraping plate 109 flows into the collection box 108 under the action of gravity and is collected by the collection box 108. The water pump 110 operates to transmit the paint in the collection box 108 back to the paint tank 104 through the return pipe 111, solving the problem that the coloring roller and the coating roller cooperate with each other to paint the parts. After the painting is completed, a large amount of paint remains in the coloring roller, which is not convenient to collect and easily causes the waste of paint raw materials.

[0027] Among them, the mounting plate 112 is fixedly connected to the support plate 103 and is located below the support plate 103. A plurality of the spray heads 113 are respectively fixedly connected to the mounting plate 112 and are located below the mounting plate 112. A plurality of the mounting cotton pieces 114 are respectively fixedly connected to the mounting plate 112 and are respectively located outside the plurality of the spray heads 113. The mounting plate 112 is used for the support plate 103 and the plurality of the spray heads 113, and a plurality of through holes are provided in the mounting plate 112 and can communicate with the spray heads 113. The paint in the paint tank 104 flows into the mounting plate 112 and is transmitted to the plurality of the spray heads 113 through the through holes in the mounting plate 112. The spray heads 113 spray out the paint, and the paint is absorbed by the mounting cotton pieces 114. After the mounting cotton pieces 114 are saturated, the paint is dripped onto the sponge cylinder 106 through the mounting cotton pieces 114, preventing the paint from splashing onto the conveyor belt 101 and causing waste of raw materials.

[0028] Among them, the hanging plate 115 and the mating plate 116 are oppositely arranged below the support plate 103. The motor 117 is fixedly connected to the hanging plate 115 and is located on the outer side wall of the hanging plate 115, and the output end of the motor 117 penetrates through the hanging plate 115. The rotating shaft 118 is fixedly connected to the mating plate 116 and is located on the side of the mating plate 116 close to the hanging plate 115. The coating roller 105 is rotatably connected between the motor 117 and the rotating shaft 118. The hanging plate 115 is used for mounting the motor 117, the mating plate 116 is used for mounting the rotating shaft 118, the motor 117 and the rotating shaft 118 cooperate with each other to fix the coating roller 105. When the motor 117 operates, it drives the coating roller 105 to rotate, thereby realizing the primer coating of the parts by the coating roller 105.

[0029] When using a roll coating mechanism for an anti-corrosion primer of the present utility model, the paint in the paint tank 104 flows into the spray head 113 through multiple through holes in the mounting plate 112. The spray head 113 sprays the paint, which is absorbed by the mounting cotton 114 outside the spray head 113 and finally drips onto the sponge cylinder 106. The motor 117 operates to drive the coating roller 105 and the sponge cylinder 106 to rotate. The scraper 109 on the collection box 108 scrapes the sponge cylinder 106 to remove the excess paint on the sponge cylinder 106, avoiding the waste of raw materials caused by the paint remaining in the sponge cylinder 106. At the same time, the paint scraped by the scraper 109 flows into the collection box 108 under the action of gravity and is collected by the collection box 108. The water pump 110 operates to transport the paint in the collection box 108 back to the paint tank 104 through the return pipe 111, solving the problem that when the coloring roller and the coating roller cooperate with each other to paint the parts, a large amount of paint remains in the coloring roller after painting, which is inconvenient to collect and easily causes waste of paint raw materials.
