[0004] In the above scheme, the seat is fixed by an extrusion head and then the seat surface is sprayed with plastic by a nozzle, which still has the following disadvantages: during the spraying process of the seat, this device can only spray the upper part of the seat, which easily leads to uneven spraying on the seat surface, thereby reducing the spraying effect of the seat surface and further reducing the spraying quality of the seat. Utility Model Content

[0005] The purpose of the utility model is to provide a spraying device for treating the surface of a seat back, so as to solve the problem that during the spraying process of the seat, only the upper half of the seat can be sprayed, which easily leads to uneven spraying on the seat surface, thereby reducing the spraying effect of the seat surface.

[0006] In order to achieve the above-mentioned utility model objectives, the utility model adopts the following technical solutions: a plastic spraying device for surface treatment of a chair back, comprising a box body, a mounting cylinder is fixed to the inner bottom surface of the box body, a driving motor is fixed to the inner wall of the mounting cylinder, a placement frame is fixed to one end of the output shaft of the driving motor, and fixing modules are arranged on the left and right sides of the placement frame, a mounting hole is opened on the rear side of the inner wall of the box body, an electric slide rail is fixed to the inner wall of the mounting hole, a connecting block is fixed to the front side of the slider of the electric slide rail, a shell is fixed to the front side of the connecting block, a plurality of fixing holes are opened on the inner wall of the shell body, a nozzle is fixed to the inner wall of the fixing hole, two connecting hoses are fixed to the top surface of the shell body, one end of the connecting hose extends into the shell, a water tank is fixed to the top surface of the box body, a water pump is arranged in the water tank, and the other end of the connecting hose passes through the top surface of the box body and extends into the water tank.

[0007] Preferably, two installation grooves are provided on the rear side of the inner wall of the box body, and heating plates are fixed to the inner walls of the installation grooves.

[0008] Preferably, a protective door is rotatably connected to the right side of the box body via a hinge, a temperature sensor is fixed to the front side of the protective door, and a sensing end of the temperature sensor extends to the rear side of the protective door.

[0009] Preferably, limit blocks are fixed on both the left and right sides of the shell, and limit grooves are provided on both the left and right sides of the inner wall of the box body, and the limit blocks and the limit grooves are slidably arranged.

[0010] Preferably, a water storage tank is provided on the inner bottom surface of the box body, a water outlet hole is provided on the left side of the box body, the water outlet hole is connected to the water storage tank, and a water outlet pipe is fixed to the inner wall of the water outlet hole.

[0011] Preferably, a placement hole is opened on the front side of the protective door, and a transparent panel is fixed to the inner wall of the placement hole.

[0012] Compared with the prior art, the spraying device for treating the surface of a chair back using the above technical solution has the following beneficial effects:

[0013] 1. The chair back can be sprayed with plastic by the cooperation of the electric slide rail and the nozzle. When the staff places the chair back on the top surface of the placement frame, they can first fix the chair back through the fixing module, and then start the drive motor and the electric slide rail. At this time, the drive motor will drive the placement frame and the chair back to rotate. At the same time, the electric slide rail will drive the shell and the nozzle to move up and down, so that the nozzle will evenly spray the paint on the surface of the chair back through the connecting hose, thereby improving the spray effect of the chair back surface and the spray quality of the chair back;

[0014] Second, the heating sheet can heat the cavity inside the box, so that the paint can better adhere to the surface of the chair back, thereby improving the efficiency of the chair back spraying. The temperature sensor can sense the internal temperature of the box to prevent the high temperature inside the box from affecting the spraying results, so that the staff can quickly adjust the temperature;

[0015] 3. The shell can be limited by the cooperation of the limit block and the limit groove. When the electric slide rail drives the shell to move up and down, the limit block will slide on the inner wall of the limit groove, so that the shell is more stable when moving, thereby assisting the spraying device to spray the chair back. The paint produced by the spraying can be collected through the water storage tank, so that the collected paint can be discharged through the water outlet pipe, which is convenient for the staff to filter and process the paint, thereby improving the utilization efficiency of resources.

[0016] Fourth, the transparent panel can facilitate the staff to visually observe the spraying status of the chair back, so that the staff can record the spraying data of the chair back, and then facilitate the staff to adjust the spraying data of the chair back. BRIEF DESCRIPTION OF THE DRAWINGS
