A spraying tool for elongated automotive interior parts

Abstract

A spraying tool of a long automobile interior trim part comprises at least three spraying guns (10) annularly arranged in a spaced manner. The spraying tool comprises an angle space adjusting mechanism (100) and a spraying sector adjusting mechanism (200); the angle space adjusting mechanism (100) comprises a first annular main body (1) which is provided with at least three nozzle bases (3) in a sliding manner, the spraying guns (10) are arranged on the nozzle bases (3) in a sliding manner in the radial direction of the first annular main body, the first annular main body (1) comprises a first guide rail (4), a second guide rail (17) and outer teeth (5), the outer teeth (5) are arranged on the outer edge of the first annular main body (1), each nozzle base (3) comprises a first guide groove (7), a second guide groove (18) and a walking gear (8), and the top side center point of each first guide groove (7), the top side center point of each second guide groove (18) and the axis of each walking gear (8) form the isosceles triangle. The spraying tool of the long automobile interior trim part is suitable for spraying a long workpiece, the coating supplementing process is removed, the painting rate is high, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of spraying, in particular to a spraying tool for long automotive interior parts. Background technique [0002] For automotive interior parts, with the advancement of technology and the improvement of consumers' requirements for vehicle interiors, higher requirements are put forward for the coating of interior parts. No matter what kind of spraying method is used in the spraying process, it is impossible to make the paint mist completely adhere to the surface of the coated workpiece, and a part of overspray mist will always be generated. The higher the coating adhesion rate of the workpiece, that is, the higher the transmission efficiency of paint mist, the less overcoat mist generated. Especially for elongated workpieces, there are many methods in the prior art to improve the coating adhesion rate. For example, a ring-shaped spray gun is used, and the ring-shaped spray gun is provided with a gap, which al...

Problems solved by technology

However, the effective spraying distance of the rotary cup spraying method is 200mm, and the sprayed paint flow is a conical sprayed paint flow. Question 2 is: how to change it to a fan-shaped sprayed paint flow with a certain thickness, so as to adapt to multi-spraying long automotive interior parts. spraying requirements
