Large-particle foreign matter detecting and discharging device for powder coating production

Abstract

The invention relates to the field of coating production, and discloses a large-particle foreign matter detecting and discharging device for powder coating production. The device comprises a shell, afirst motor and a second motor, wherein the side wall of the shell is fixedly provided with the second motor, one end of an output shaft of the second motor is fixedly provided with a first belt pulley, one end of the first belt pulley is fixedly provided with a rotating shaft, one end of the rotating shaft penetrates through and extends into the shell and is rotationally installed inside a firstbearing fixedly installed on the inner wall of the shell through a rotating shaft. According to the scheme, the second motor, a belt and a first reciprocating lead screw box fixing assembly are arranged, the second motor is started to drive a first belt pulley to rotate and drive a rotating shaft to rotate, the rotating shaft rotates to drive a cam to rotate, a piston plate is driven by elastic force of a second spring to slide downwards to drive a screen plate and a second screen to move downwards, therefore, up-and-down movement of the screen plate and the screen is achieved, small powder leaks down, large particles are left on the screen, and the function of discharging and detecting the large particles is achieved.

Description

technical field [0001] The invention relates to the technical field of paint production, more specifically, to a large-particle foreign matter detection and discharge device for powder paint production. Background technique [0002] The so-called paint is applied on the surface of the material to be protected or decorated, and will form a firm film on the surface of the object to be coated. In China, paint is also called paint, mostly resin, oil and emulsion. The types of paint There are many, among which powder coating is one of the most common coatings. It is mainly composed of solid powder such as solid resin. In the process of solid powder production, large particles of foreign matter are often mixed into the finished product, which affects the use of coatings. , to sum up, there is a need for a large particle foreign matter detection and discharge device for powder coating production. However, the prior art inspection device does not have the function of checking and s...

[0002] The so-called paint is applied on the surface of the material to be protected or decorated, and will form a firm film on the surface of the object to be coated. In China, paint is also called paint, mostly resin, oil and emulsion, etc. The types of paint There are many, among which powder coating is one of the most common coatings. It is mainly composed of solid resin and other solid powders. In the process of solid powder production, large particles of foreign matter are often mixed into the finished product, which affects the use of coatings. , to sum up, there is a need for a large particle foreign matter detection and discharge device for powder coating production

However, the prior art inspection device does not have the function of checking and sorting the circulating parts, and the inspection and discharge are often not up to the standard after one inspection and discharge, resulting in the presence of large particles of foreign matter in the subsequent powder coating, which affects the use of the coating. The screening technology in the prior art only has a screening step, and when the powder is introduced into the sieve, because the powder is piled up in one place, when screening larger particles, the screening is not complete enough, and certain improvements are needed
