The retractable paint booth is widely used for environmental protection painting of complete machines or parts in machinery, automobile, aviation, aerospace, military industry, railway, motor, construction, water pump, machine tool, furniture and other industries.



The telescopic front chamber of the telescopic paint booth is a steel frame structure, which can be moved back and forth. The sliding connection mechanism between the frames ensures that the frame moves vertically and parallel along the track on the ground under the driving of the driving device, and at the same time drives the tarpaulin to unfold and close. When moving the front chamber to shrink and close, move the workpiece into the work area, and paint or polish the workpiece when unfolding. During the working time without painting, the front room can be closed to make room for other cross operation procedures with painting. The equipment can meet the requirements of customers. The paint mist treatment equipment can be wet (no pump water curtain, water curtain) or dry (filter cotton, baffle plate). After spray treatment, the organic waste gas enters the waste gas treatment device for purification and high-altitude exhaust. The filtered waste gas meets the environmental protection standard.



All components can be customized (such as size, material, brand, process, function, etc.)

Apart from the door frame, the rest parts are canvas support net, which is the framework for installation and connection of flame-retardant canvas. It is composed of multiple groups of profile skeleton, and the whole relatively independent skeleton is connected together through a scissors type expansion mechanism to form a stable whole

The two canvas support nets are connected by a scissor type telescopic mechanism, whose structural size determines the amount of expansion and contraction. At the same time, a set of scissor type telescopic mechanism is arranged at the upper and lower sides of each side to ensure that the upper and lower sides can achieve expansion and contraction at the same time, and a synchronous motion mechanism is formed between the two through a connecting rod

Industrial flame-retardant PVC canvas is used between the entire grid, which is the "wall panel" that forms a relatively closed operation room and also the "room" that ensures the orderly flow of air. During installation, one piece of industrial canvas is used for every two support nets

The drive part adopts a reduction motor, which is transmitted to multiple long shafts, and then is synchronously transmitted to the driving wheels on both sides by the sprockets at both ends of the long shaft. The whole drive adopts three-level protection for forward and backward: two-way two-level travel protection, and the rail terminal is set with limit stops; There are control boxes on both sides of the door post, which is easy to operate; A running warning light is set on the top of the spray chamber.
