Description

Technical Field

[0001] The present invention relates to the technical field of color sorter sorting, and in particular to a material discharging and sorting device for a color sorter. Background Art

[0002] Color sorters are devices that automatically separate particles of different colors from granular materials using photoelectric detection technology based on differences in the optical properties of the materials. They are widely used in areas such as bulk materials, packaged industrial products, and food quality testing and grading. Since color sorters can only perform color screening and cannot perform other types of screening, they usually use a sorting device to perform further sorting when unloading the sorted materials to sort out the materials that meet the requirements.

[0003] After searching, the Chinese invention patent with patent number CN201710363861.X discloses a material unloading and sorting device for a color sorter, including a mounting base, on which are mounted several vibrating unloading mechanisms; the vibrating unloading mechanisms include a vibrator, a vibrating material tray, a material unloading limiter tray, and a lane tray; the vibrating material tray includes a stepped material tray, a dividing plate, and a bottom plate; the bottom plate is arranged on the bottom surface of the stepped material tray, and several of the dividing plates are fixed side by side on the bottom plate; one surface of the lane tray is a wavy surface; the vibrating material tray is fixed on the vibrator; the discharge port of the vibrating material tray cooperates with the material unloading limiter tray, and the material is dropped onto the lane tray by controlling the material unloading limiter tray;

The present invention sets a sorting net box with multiple sorting holes, which can sort materials according to their size, so that the preliminarily qualified materials fall through the sorting holes, while the large-volume unqualified materials remain on the sorting net box, completing the sorting of large and small volumes.

[0021] 2. The present invention adopts the setting of the lifting frame, which can realize up and down reciprocating vibration through the cooperation of the transmission mechanism and the reciprocating mechanism after the servo motor is started, thereby driving the material on the sorting net box to vibrate up and down, thereby improving the efficiency of material sorting through vibration, and performing comprehensive sorting without any errors or omissions.
