Problems solved by technology

The spraying quality of manual work is too dependent on the proficiency of the operator. Each operator has different techniques. It is difficult to control the uniform rotation of the workbench, the control of the spray gun, the thickness and uniformity of the paint film, etc., resulting in unstable spraying quality. The long-term efficiency is low, the waste of plastic paint is large, the scrap rate is high, and the product cost is high; therefore, the existing technology has problems and deficiencies such as poor quality consistency, high cost, low efficiency, and large waste

Abstract

The invention discloses an automatic inner wall spraying device for round cup-shaped injection molding products. The automatic inner wall spraying device comprises a rotary workbench (1), a base (12), a motor (13), an air cylinder (2), a cantilever (3), a spray gun (31), a bracket (23), a PLC (Programmable Logic Controller) (4), an electromagnetic valve (5) and a frequency-conversion speed regulator (6). According to the invention, the device consisting of the rotary workbench, the motor, the air cylinder, the cantilever, the spray gun, the PLC, the electromagnetic valve and the frequency-conversion speed regulator is adopted; and when the automatic inner wall spraying device works, the round cup-shaped product is clamped on the rotary workbench and driven by the motor to rotate at a constant speed, the air cylinder drives the cantilever to carry the spray gun to be inserted into a cavity of the round cup-shaped product to spray up and down at a constant speed, and the PLC controls the spray gun to be started and stopped through the electromagnetic valve and controls the air cylinder to act up and down. Due to the technical scheme that the frequency-conversion speed regulator controls the rotating speed of the motor, the inner wall of the round cup-shaped injection molding product is sprayed to reach the purposes of keeping consistency of quality, reducing cost, improving efficiency and reducing waste.

Description

technical field [0001] The invention relates to an automatic spraying device, in particular to an automatic inner wall spraying device for a round cup-shaped injection molding product used for spraying plastic paint on the inner wall of the round cup-shaped injection molding product. Background technique [0002] The plastic paint is sprayed on the inner wall of the circular cup-shaped injection molding product. The existing technology adopts manual operation, that is, the circular cup-shaped product is placed on the rotary worktable, and the worktable is manually rotated with one hand, and the spray gun is inserted into the circular cup with one hand. The interior of the product is sprayed. The spraying quality of manual work is too dependent on the proficiency of the operator. Each operator has different techniques. It is difficult to control the uniform rotation of the workbench, the control of the spray gun, the thickness and uniformity of the paint film, etc., resulting...
