an automatic fuel injector

Abstract

The invention discloses an automatic oil spraying machine which is accurate in spraying, safe and environmentally friendly. The automatic oil spraying machine comprises a machine frame, a control cabinet, an oil spraying chamber, an oil spraying assembly, an oil storage box, a switch and a workpiece fixing mechanism and is used for completing oil spraying work of the sprayed surface of a workpiece, and according to input processing parameters, the control cabinet controls a driving motor, an oil pump and an electromagnetic oil valve so as to accurately control the spraying quantity and the spraying position. A sealed cavity is formed by a fixture, the workpiece and the oil spraying chamber, so that oil sprayed out of an oil spraying nozzle in the oil spraying chamber is isolated from external air, the oil not adhering to the workpiece can flow back into the oil storage box via a backflow pipe through an overflowing hole in the bottom of the oil spraying chamber to be repeatedly used, the spraying cost of filters is greatly saved, the risk that highly volatile oil mist is diffused into air is avoided, and filter spraying is safer and environmentally friendlier.

Description

technical field [0001] The invention relates to the technical field of fuel injection equipment, in particular to an automatic fuel injection machine. Background technique [0002] In the manufacturing process of automotive air filters, it is a common process to spray oil on the surface of the filter. Spraying a layer of adsorbed oil on the surface of the filter can further improve the filtration accuracy of the automotive air filter. In order to make the adsorbed oil better adhere to the filter, the adsorbed oil is usually mixed with a volatile organic solvent before spraying when spraying oil. After the volatile organic solvent volatilizes, the adsorbed oil immersed in the filter with the organic solvent is retained. in the filter. In the current production process of automobile air filters, the process of spraying oil on the surface of the filter is usually carried out by manpower manually operating the spray gun. Unevenness and deviation of spraying position will event...

Problems solved by technology

In the current production process of automobile air filters, the process of spraying oil on the surface of the filter is usually carried out by manpower manually operating the spray gun. Unevenness and spraying position deviation, resulting in reduced product quality

Moreover, manual oil spraying is likely to cause waste of oil, and the oil that is not attached to the filter is difficult to recycle; at the same time, the volatile oil mist generated during the manual spraying process will also diffuse into the air, which is easily inhaled by personnel and affects the health of personnel At the same time, the flammable oil also increases the risk of fire, and the leakage of oil will also pollute the local environment
