The spray booth is mainly composed of a water rotating chamber, a drafting device, a water treatment device, a special trolley, a reversing turntable, a guide rail and the like. The workpiece conveying pattern is rotated in the frame, which can be continuously conveyed, continuously painted, and the rotating parts of the painted parts are rotated, which is convenient and labor-saving and flexible. The transportation is mainly based on the trolley, and the special spreader for getting on the vehicle before painting and getting off after painting.

After the painting is completed, it will continue to advance and there is no need to return to the next step. The air supply mechanism is arranged on the upper part of the room, the temperature is adjustable, and the air extraction system is arranged underground to form a flow from top to bottom. The air flow speed can be manually controlled, and the selection is performed according to requirements, and the speed is generally controlled at about 0.5 s.

The safety system is equipped with a fully automatic alarm device to constantly monitor the safety status of the indoor electrical equipment. At the back of the spray booth, a drying chamber is provided for use. The plane of the aisle-type lacquering room is a schematic diagram of the painting process of the aisle spray booth and its characteristics. In the painting of the machine tool, the two parts of the initial paint and the whole machine are painted, because the requirements of the initial paint are higher than the paint of the whole machine. It is low, and the main process steps include the whole machine's double-painting process. It can be seen that the whole machine's double-painting process is representative.

At the beginning of the machine tool repainting, the workpiece is placed on a special trolley for painting, cleaning, putty, sanding, and spraying. These processes are applied for a long period of time. After the coating meets the quality standards, the painted parts are transferred from the painting site to the spray paint room. The number of sprays and the interval are determined by the paint type. After spraying, it is dried in a drying chamber.

After the paint film is dried for a certain period of time, the painted parts are transferred out of the drying room to the original coating site for the next process water sanding. After the water grinding, the paint booth is sprayed with the varnish. Under normal circumstances, it is enough to spray 2 or 3 coats of varnish, and the varnish is sprayed into the drying room for drying. In the drying room, the drying time of the paint is determined according to the paint type and process requirements, and the paint film is dried after being dried. Seal the work. When the machine tool is packaged, it is necessary to pay attention to the protection of the paint film, and not to carry the "nen" packaging, the main process route of the spray painting operation of the aisle spray booth.

The above analysis of the aisle spray booth, we believe that the spray booth has the following advantages: (1) high efficiency. The working area of ​​this room is large. The small and medium-sized machine tools can accommodate 3 to 4 sets of spraying at a time, and 10 to 12 sets can be completed within 8 hours, which basically meets the production of medium and large batches of machine tools. At the same time, the working area of ​​the room can be determined according to actual needs.

(2) The operation is convenient and flexible. The workpiece is painted on the trolley from the beginning of the cleaning. The operation is carried out by manual or mechanical traction of the trolley and the guide rail. The friction is small, the operation is labor-saving, and the turning is regulated by the rotating disc. After the workpiece enters the spray booth and finishes spraying, it does not need to retreat and continue to move forward. The subsequent workpiece can be attached to the coating. The front workpiece continues to the next process, and there is no retreat in the middle.

(3) The effect is good. The room adopts the upper suction and the lower suction to form the upper and lower airflow to take away the paint mist, and then remove the paint mist by the water spin treatment, the paint mist removal rate can reach more than 95%, and the toxic gas content in the sprayer's breathing zone reaches National health standards. (4) It is beneficial to protect the health of the painters and protect the environment. Since most of the paint is carried out in the paint booth and can be processed centrally, the working environment of the painter is greatly improved, and the outdoor environment is effectively protected. (5) It is beneficial to improve the surface quality of the paint film and promote the use of new machine tool coatings. Due to the use of the spray booth and the drying chamber, the process of forming the paint film after painting and the drying process are carried out in a clean room, so the volatile The surface quality of the paint film is easily guaranteed.

At the same time, the appearance quality and intrinsic quality of the new machine tool coatings can meet the quality standards. Although the aisle spray booth has the above advantages, it also has some shortcomings, such as: one-time investment, large maintenance and so on.

As long as we carry forward the advantages of the aisle spray booth and make up for the deficiencies, we must give full play to the superiority of the aisle spray booth, and show its advantages in improving the quality of the paint film, the quality of the coating environment and the health of the painters. Potential energy.
