Description

Background color self-adjusting device for color sorter

Technical Field

The utility model relates to a look selects quick-witted technical field, specifically is a background colour self-interacting device for look selects machine.

Background

The color sorter industry generally uses a white background light with the addition of a background plate of multiple colors to control the background color. The switching of colors is realized by controlling the rotation of four surfaces of the background plate, and the main defects are as follows: (1) the color is single, and four surfaces of a background plate can only provide four colors at most; (2) the motor rotates to drive the background plate to rotate so as to change the direction of the background plate, certain errors exist, the errors are large, the errors are mainly reflected on the comprehensive errors among the angle device, the motor and the coupler, and the errors can grow slowly along with the time, so that the long-term stability of equipment is not facilitated; (3) the structure is complicated, and the technology is loaded down with trivial details: the structure of the device comprises three main parts, an angle device, a motor and a coupling device. The angle gauge needs to be calibrated manually before being installed, so that time is consumed, and faults (human errors) are easy to occur; the control of the motor can well control the forward and reverse rotation and start and stop of the motor only by a special motor control chip; the coupling device needs machining or die sinking manufacturing, and the requirement on precision is high; (4) the cost is high, the main cost is reflected on the processing of the background plate, because the background plate requires a flat surface and uniform reflected light, so that the surface needs to be subjected to professional baking finish treatment, and the cost of each background plate is more than 1000 yuan.

In view of the above disadvantages, especially the cost, a simplified background plate device is provided, i.e. the background plate is not rotated and the background plate is made of a single color, and the cost can be reduced by about 60%.

However, under the condition of reducing the cost, the scheme also causes the use of the background plate to be limited, and the background plate has a single color and cannot meet the requirement of more material selection occasions.
