Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of board pretreatment, and specifically relates to a board coating surface pretreatment device. BACKGROUND

[0002] Before coating, the wood board needs to be surface pretreated to repair the defects on the board surface, such as bleaching treatment. If the wood board is not uniform in color or has color spots, the wood board can be made lighter and more uniform in color through bleaching treatment, thereby providing a better color basis for subsequent coating.

[0003] When bleaching the wood board, the wood board is usually placed horizontally. The horizontally placed wood board is easier to be coated with bleaching agent and wiped, and the horizontal placement can make the bleaching agent fully contact with each part of the wood board, especially the large-area flat part, so that a relatively uniform bleaching effect can be obtained. However, the horizontal placement can easily cause the liquid to gather in low-lying places. This can cause some parts of the wood board to be bleached excessively, especially at the edges or joints.

[0004] Vertical bleaching can reduce liquid gathering, but the operation is difficult, and the risk of uneven bleaching is high.

[0005] Therefore, the present application provides a board coating surface pretreatment device, which can adjust the posture and front and back surfaces of the board according to the state. SUMMARY

[0011] The included angle between the grid frame and the carrier can be adjusted within the range of 0-90°;

[0012] The two groups of grid frames can cooperate with each other to realize the transfer and turning of the board, and promote the discharge of the bleaching liquid infiltrated into the wood gap.

[0013] Preferred technical solution one: one end of the top surface of the two groups of grid frames close to the convex seat is fixedly connected with a convex rib, and the inclined bottom end is in contact with the convex rib when the wood is inclined;

[0014] When the two sets of grid frames are erected, the distance between the two sets of grid frames is greater than the thickness of the wood.

[0015] Preferably, the table top is concave, forming a pool body capable of receiving the bleaching solution.

[0016] Preferably, a liquid collecting tank is fixed to the bottom of the table, and the top wall of the liquid collecting tank is provided with a flow guide hole communicating with the bottom wall of the pool body.

[0017] Preferably, the height of the convex ridge is less than the distance between the two sets of grid frames when the two sets of grid frames are erected.

[0018] Preferably, the convex ridge is composed of a plurality of convex teeth fixedly distributed along the width direction of the grid frame at one end of the convex seat on the top surface of the grid frame, and the convex teeth on the two sets of grid frames are staggered.

[0019] Preferably, the convex handle end head fixed on the convex shaft on each set of grid frames is connected to the table through a set of telescopic rods.
