Embodiment 1

[0043] Embodiment one is basically as attached Figure 1 to Figure 5 Shown:

[0044] Paint and flow coating production line for door panels, including frame 1, conveyor belt 3, grinding unit, negative pressure unit, adhesion unit, and flow coating unit, the adhesion unit of the grinding unit, drying chamber 10, and flow coating unit convey the board along the conveyor belt 3 The directions are distributed sequentially, and there is a negative pressure unit behind each grinding unit.

[0045] to combine figure 1 , the grinding unit includes three rotating rollers 4 that are connected in rotation on the frame 1, each rotating roller 4 is driven by a separate motor, the outer periphery of the rotating roller 4 is bonded with sandpaper, and the rotating roller 4 is parallel to the conveyor belt 3; The rotating speeds of the rotating rollers 4 are different, and the rotating speeds of the rotating rollers 4 increase sequentially from right to left.

[0046]The negative pressure ...

Embodiment 2

[0059] combine Figure 6 , embodiment two increases drying chamber 10 on the basis of embodiment one, namely between adhesion unit and shower coating unit, drying chamber 10 is set, is convenient to adopting the board after alcohol adhesion sawdust and dust to dry, After the board is dry, do the spray coating, so as to avoid the situation that the board is not completely dry due to the presence of alcohol, which will affect the quality of the subsequent board.

Embodiment 3

[0061] Embodiment three is basically as attached Figure 7 to Figure 11 As shown, embodiment two has carried out following improvement on the basis of embodiment one, specifically as follows:

[0062] The number of conveyor belts 3 is three, and a reflow tank 12 is arranged between the two conveyor belts 3 , and the reflow tank 12 is facing the edge 13 of the coating knife of the coating substrate 2 .

[0063] combine Figure 10 , A recovery box 14 is also fixedly installed on the frame 1, and the recovery box 14 communicates with the return tank 12.

[0064] combine Figure 8 to Figure 11 , the backflow groove 12 is slidably connected with a moving rod 15 (the moving rod 15 can move in the length direction of itself), the bottom of the backflow groove 12 is arc-shaped, and the moving rod 15 is covered with two springs 16, and the spring 16 and the backflow groove The arc-shaped bottom of 12 offsets; The middle part of moving bar 15 is fixedly connected with baffle plate 17...

Abstract

The invention relates to the technical field of curtain coating equipment, and particularly discloses a door plate lacquering curtain coating production line. The door plate lacquering curtain coatingproduction line comprises a rack, a conveying belt, a grinding unit, a negative pressure unit and a curtain coating unit. An adhesion unit is arranged between the negative pressure unit and the curtain coating unit, and comprises a driver, an adhesion belt and multiple liquid conveying rollers, the driver drives the liquid conveying rollers to rotate, the adhesion belt is made of fabric, the liquid conveying rollers are sleeved with the adhesion belt, a cavity is formed in each liquid conveying roller, a solution is arranged in the cavities, a circulation channel is arranged on the liquid conveying rollers, the circulation channel communicates with the cavities, plugging blocks are in sliding connection to the circulation channel, and elastic parts are connected between the other ends ofthe plugging blocks and the corresponding inner wall of the circulation channel. Circulation grooves enabling the exterior to communicate with the cavities are formed in the circulation channel, and the circulation grooves can be blocked by the plugging blocks. The problems that in the prior art, the negative pressure absorbing manner is adopted for absorbing ground-down saw dust, absorbing is notthorough, the saw dust is adhered to a door plate, and the door plate appearance quality is affected are solved.

Description

technical field [0001] The invention relates to the technical field of flow coating equipment, in particular to a door panel paint flow coating production line. Background technique [0002] The door panel made of board needs to be polished, sprayed and leveled. After the leveling, it can be formed by natural drying or drying; in the production of the door panel, the condition of the surface of the board after the board is polished is related to the uniformity of the subsequent coating of the board. In order to facilitate the control of the quality of the door panel, the quality of the leveling of the paint and the leveling of the paint is generally continuous. [0003] In the prior art, after the board is polished, negative pressure is generally used to suck away the polished wood chips from the board. However, the negative pressure adsorption method is often not completely absorbed, and tiny wood chips and dust adhere to the board. The condition in which sawdust or dust f...
