[0004] The applicant found that there are some shortcomings in use: since the telescopic height of the electric push rod is limited and the height of the spray plate cannot be adjusted, when spraying a wider table top, the distance between the load-bearing plate and the spray plate may not be large enough, which makes it difficult to flip the table top, making it impossible to spray paint a wider table top, which has certain limitations.

[0005] Therefore, the utility model designs a wood product surface spraying device to solve the problems existing in the prior art. Utility Model Content

[0006] The utility model aims to provide a device for spraying paint on the surface of wooden products to solve the problems raised in the above-mentioned background technology.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a device for spraying paint on the surface of wooden products, comprising: a processing box, both ends of the lower side walls of the processing box are equipped with support legs, a box door is provided in the middle of one end of the processing box, a paint box is installed on the top side of the processing box, a discharge pipe is connected to the lower side of the paint box through a water pump, a hollow plate is provided on the upper part of the interior of the processing box, the hollow plate and the discharge pipe are connected through a telescopic bellows, a plurality of nozzles are provided at the bottom of the hollow plate, a support plate is provided directly below the hollow plate, and the pump Electric cylinders are provided on the top and bottom of the work box, and the output ends of the two electric cylinders are respectively connected to the top of the hollow plate and the bottom of the support plate. The processing box is provided with a turning mechanism for turning over the wooden products, and one end of the processing box is provided with a blowing mechanism for blowing hot air to the wooden products. The hollow plate is provided with an adjusting mechanism for saving paint. The electric cylinder is installed on the outside of the processing box, so that the extension stroke of the electric cylinder is larger, and the distance between the hollow plate and the support plate is increased by moving them away from each other, so that when spraying a table top with a wider width, it will not affect the turning over of the table top.

[0008] Preferably, the flipping mechanism includes two electric push rods, which are respectively installed in the middle of both sides of the processing box, and a connecting plate is installed on the output end of the electric push rod, and a driving motor is installed on the connecting plate. The output end of the driving motor is connected to a clamping bar, and the electric push rod is extended to drive the two supporting bars to approach each other, clamping and fixing the two sides of the table top, and then the driving motor is driven to rotate 180 degrees synchronously, so that the table top can be rotated 180 degrees, which is convenient for painting the other side of the table top.

[0009] Preferably, a rubber anti-skid pad is provided on one side of the clamping strip close to the support plate, and the rubber protective pad can increase the friction between the clamping strip and the side wall of the table top, thereby improving stability when turning over.

[0010] Preferably, the blowing mechanism includes an air box, which is installed in the middle of the inner wall of the processing box away from the box door. A plurality of air nozzles are provided at the end of the air box close to the support plate. A hot air blower connected to the air box is installed on the outer wall of the processing box. After spraying one side, the hot air blower is started to allow hot air to enter the air box and then be sprayed out through the air nozzle, so as to dry the side of the table top that has been sprayed with paint, accelerate the drying of the paint, and improve efficiency compared with natural air drying.

[0011] Preferably, the adjustment mechanism includes two threaded rods, which are rotatably installed on both sides of the hollow plate respectively, and a sealing plate slidably connected to the hollow plate is rotatably installed on the side where the two threaded rods are close to each other. By rotating the threaded rods to bring the two sealing plates closer to each other, the internal space of the hollow plate can be reduced, so that the nozzles on both sides of the bottom of the hollow plate cannot spray paint. When spraying a shorter table top, the waste of paint can be reduced.

[0012] Preferably, knobs are installed on the sides of the two threaded rods that are away from each other, and the knobs are convenient for workers to rotate the threaded rods.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. The utility model adopts the arrangement of electric cylinders, which are arranged outside the processing box. The extension of the electric cylinders is longer. When the table top needs to be turned over, the two electric cylinders respectively drive the support plate and the hollow plate to contract, so that the two are separated from each other, so that the distance between the support plate and the hollow plate is larger, so that when spraying a table top with a wider width, the turning over of the table top is not affected, thereby improving practicality;

[0015] 2. The utility model is provided with a blower mechanism. After one side of the table top is painted, the hot air blower is started, and the hot air enters the air box and is then sprayed on the paint surface through the air nozzle, which accelerates the drying of the paint surface. Compared with natural air drying, the time is shortened and the efficiency is improved;

[0016] 3. Through the setting of the adjustment mechanism, the utility model can rotate the threaded rod when the length of the table top is short, so that the two sealing plates are close to each other, the space inside the hollow plate is reduced, and the nozzles on both sides of the bottom of the hollow plate cannot spray paint, thereby reducing the waste of paint and saving resources.
