Description

Technical Field

[0001] The utility model relates to the technical field of wood surface treatment, and more specifically, to a spraying mechanism in a wood surface treatment device. Background Art

[0002] Wood is widely used in construction, furniture, craft carving, papermaking and many other fields. The surface of wood needs to be treated during the processing and production process. Wood spraying is a common woodworking surface treatment method that can protect the wood surface and beautify wooden furniture. Spraying equipment is usually used to evenly spray the paint on the wood surface to achieve waterproof, anti-corrosion, decorative and other effects.

[0003] After searching, the Chinese patent with publication number CN220329028U discloses a wood surface spraying device. In view of the existing wood surface spraying, most of the wood surface spraying is done manually by handheld spraying equipment. The efficiency of manual spraying is low, and the spraying speed is not well controlled, which affects the spraying speed and spraying quality. By mechanized and automated spraying of the wood surface, the problems of low spraying efficiency and poor control of spraying speed caused by manual spraying are solved, and the spraying speed and spraying quality are improved.

[0004] However, in the process of spraying the wood surface, the device mostly adopts the process of spraying on both sides separately. After spraying on each side, it is necessary to wait for the paint to dry, and then turn the wood over to complete the spraying on the other side. At the same time, it is inconvenient to spray paint on both sides of the wood surface. This method has low spraying efficiency. At the same time, it takes time to air-dry after spraying, which affects the product processing efficiency. Utility Model Content

[0005] In order to overcome the problems and defects in the prior art, the utility model provides a spraying mechanism in a wood surface treatment device to solve the problems raised in the above background technology.

[0006] To achieve the above object, the utility model provides the following technical solutions: a spraying mechanism in a wood surface treatment device, comprising a spraying box, a switch door is hinged on the front side of the spraying box, a rotating clamping mechanism is arranged inside the spraying box, an air jet mechanism is arranged on one side inside the spraying box, and a rotating spraying mechanism is arranged on the other side inside the spraying box;

[0007] The rotating clamping mechanism includes a lower clamping plate, which is arranged inside the spray box, an upper clamping plate is arranged on the top of the lower clamping plate, a threaded hole is opened on the top surface of the spray box, a threaded column is threadedly connected inside the threaded hole, a rotating disk is fixedly connected to the top of the threaded column, a bearing is installed between the threaded column and the upper clamping plate, a rotating bottom column is fixedly connected to the bottom of the lower clamping plate, a gear is fixedly connected to the outer side of the bottom of the rotating bottom column, a moving tooth plate is meshed on one side of the gear, a moving plate is fixedly connected to one side of the moving tooth plate, and a telescopic cylinder is fixedly connected to the top of the moving plate.

[0008] Preferably, the bottom of the rotating bottom column passes through the spray box and extends to the bottom of the spray box, and the telescopic cylinder is installed at the bottom of the spray box.

[0009] Preferably, the jet mechanism includes an exhaust fan, which is installed on one side of the spray box. A shell is fixedly connected to one side of the inner wall of the spray box. The output end of the exhaust fan passes through the spray box and extends to the inside of the shell. A plurality of heating wires are fixedly installed on one side of the shell away from the output end of the exhaust fan.

[0010] Preferably, the rotary spraying mechanism comprises two fixed plates, both of which are fixedly connected to one side of the inner wall of the spray box, a motor is fixedly mounted on the bottom of one of the fixed plates, and a rotating shaft is fixedly connected to the output end of the motor.

[0011] Preferably, the rotating shaft is rotatably connected to the two fixed plates, a connecting plate is fixedly connected to one side of the rotating shaft, a rotating tube is fixedly connected to one side of the connecting plate, and a plurality of spray heads are fixedly mounted on one side of the rotating tube.

[0012] Preferably, a telescopic hose is fixedly connected to the top of the rotating tube, and the top of the telescopic hose passes through the spray box and extends to the top of the spray box.

[0013] Preferably, a plurality of support columns are evenly arranged around the bottom of the spray box.

[0014] Technical effects and advantages of the utility model:

[0015] By setting a rotating clamping mechanism and an air jet mechanism, the wood is put into the spray box, and the wood is clamped by the lower and upper clamping plates at the bottom and top of the spray box. Then, the clamping plates are started to rotate, driving the wood to rotate. At the same time, multiple spray heads on one side of the spray box always spray the wood surface. The device can automatically spray the wood on multiple sides. At the same time, the outside air is introduced through the fan on one side of the spray box, and the air is heated by the heating wire, so that the wood is dried in time after spraying through the hot air flow brought in by the exhaust fan on the other side of the spray box. The wood can be quickly dried while spraying multiple sides, saving a lot of time and greatly improving the spraying and drying efficiency.

[0016] By setting up a rotating spraying mechanism, multiple nozzles are rotated back and forth by the spray box motor. While the nozzles are rotating back and forth, the entire wood is rotating all the time. During the rotation of the wood, spraying is carried out through the continuously rotating multiple nozzles, which greatly improves the uniformity of spraying. At the same time, the setting of the spray box and the switch door prevents dust from entering, preventing dust from adhering to the surface of the wood during spraying and affecting its spraying effect.
