Negative pressure removing device of color sorter

Abstract

A pushing mechanism comprises baffles fixedly connected to the two ends of the two sides of a base, a lead screw is rotationally connected between the two opposite baffles, the outer wall of the lead screw is in threaded connection with a movable seat, a sliding rod is fixedly connected between the other two opposite baffles, and the sliding rod is in threaded connection with the movable seat. The outer wall of the sliding rod is slidably connected with a movable seat, a push plate is fixedly connected between the two movable seats, and a plurality of grooves are formed in the top of the base at equal intervals. In the process of screening and removing particle materials of different sizes, due to the fact that wind power of the fan is too large, the tops of the grooves can be blocked as long as the wind power is too large; when the particles are screened, the particles needing to be screened cannot enter the corresponding grooves, the motor drives the push plate at the top to push the particles located at the tops of the grooves so that the particles can enter the corresponding grooves, and the working efficiency in the particle screening process is improved.

Description

Technical Field

[0001] The utility model relates to the field of color sorters, in particular to a negative pressure rejecting device of a color sorter. Background Art

[0002] A color sorter is a device that uses photoelectric detection technology to automatically sort out particles of different colors from granular materials based on the differences in the optical properties of the materials. That is, when the CCD sensor detects particles of different colors, the jet valve or air gun blows away the particles by blowing air, thereby achieving the screening of granular materials of different colors.

[0003] When the color sorter screens materials with particles of different colors, the existing color sorter can screen particles of multiple different sizes and colors at the same time. During the screening process, negative pressure screening is performed by the blowing of the fan, so that in this process, particles may be blown over and stuck on the top of the screening port. During the screening process, the staff needs to remove the particles of different sizes stuck on the top of the screening port, which is time-consuming and labor-intensive, and reduces the work efficiency in the material removal process.
