Embodiment Construction

[0022] Such as figure 1 As shown, the paint supply pipe 6, the paint pump 13, the branch paint supply pipe 7, the spray gun 11 and the return pipe 8 together form a solvent cleaning circulation system. When cleaning with solvent, the ball valves 31 and 33 of the air supply pipe 5 direction are in closed state, and the ball valve 32 of the paint supply pipe 6 direction is in open state.

[0023] figure 1 Among them, in addition to the solvent cleaning circulation system, it also includes a blowing and cleaning system. Using this system, the compressed and filtered gas passes through the air pipe 5, leads to the paint supply pipe 6 and the distribution device, and then enters the branch paint supply pipe 7, the spray gun 11, and enters the The return pipe 8 is blown and cleaned. At this time, the ball valve 32 in the direction of the paint supply pipe 6 is in a closed state, while the ball valves 31, 33 in the direction of the air supply pipe 5 are in an open state.

Abstract

The invention discloses a cleaning device of a paint supply system and the method thereof. The device comprises a paint supply system cleaning device which comprises a solvent cleaning circulation system. The solvent cleaning circulation system sequentially comprises a paint pump, a paint supply pipe, a spraying gun and a counter flow pipe; the paint supply pipe is provided with a paint supply valve. The invention is characterized in that the invention also comprises a blowing and washing system which is communicated with the solvent cleaning circulation system by a first air supply valve. The invention utilizes the characteristic that the cleaning solvent is volatile and the high pressure air to blow, leads the paint supply system to be fast cleaned, ensures no or little paint slag or cleaning solvent is residual in the paint supply pipeline and the spraying gun and can meet the requirement of clean paint supply system when paints out of more different manufactures and different types are alternatively sprayed. Furthermore, the design of the structure sufficiently considers the utilization of original resource, thus having little investment and convenient installation. The mechanism used by the method is simple and easy to be installed; the cleaning solvent is saved; meanwhile, the poor phenomena such as paint mark or paint void, etc. are reduced, and the cost is reduced.

Description

technical field [0001] The invention relates to a cleaning method and device for a paint supply system for spraying, which is convenient for an auxiliary cleaning device to clean the spraying system. technical background [0002] The cleaning of the paint supply system is an important process in the spraying field, and the quality of the cleaning effect of the paint supply system directly affects the quality of this batch of products, the operation stability and safety of the next batch of production. In paint supply systems, the cleaning aid is connected between the paint pump and the return line. With the development of automatic spraying lines, the paint supply system, as a subsystem of the spraying system, plays a vital role in improving production capacity and ensuring product quality. [0003] Especially in large-scale production, the spraying paint supply system must adapt to different manufacturers and different types of paints, and different manufacturers and diffe...
