Description
Technical Field
The utility model relates to a look selects quick-witted technical field, in particular to nut look selects machine.
Background
The color sorter (color sorting machine) is a device for automatically sorting out heterochromatic particles in particle materials by utilizing a photoelectric detection technology according to the difference of optical characteristics of the materials. The color selector mainly comprises a feeding system, an optical detection system, a signal processing system and a separation execution system. Color sorters are currently used in the field of discrete materials or packaging industries, food quality inspection and classification. The main technical indexes of the color selector comprise processing capacity, color selection precision and carry-over ratio.
(1) Throughput of treatment
The processing capacity is the amount of materials which can be processed per hour, and the factors influencing the processing capacity per unit time are mainly the moving speed of a servo system, the highest speed of a conveyor belt and the purity of raw materials. The servo system has high movement speed, so that the actuator can be quickly conveyed to the position corresponding to the impurity, the speed of the conveying belt can be increased, the processing capacity is increased, and otherwise, the speed of the conveying belt is reduced. The throughput per unit time is proportional to the speed of the conveyor belt, with the faster the conveyor belt speed, the greater the throughput. The processing capacity per unit time is also related to the proportion of impurities contained in the raw material, and if the impurities are few, the larger the interval between the two impurities is, the longer the reaction time is left for a servo system, and the speed of the conveyor belt can be increased. And the processing capacity per unit time is closely related to the required selection precision.
(2) Accuracy of color selection
The color sorting precision refers to the ratio of the mass of the material containing the heterochromatic particles after the heterochromatic particles are removed from the qualified sampling product to the mass of the qualified sampling product, and the mass is expressed in percentage. The color sorting precision is mainly related to the moving speed of the conveying belt and the purity of the raw materials, the slower the moving speed of the conveying belt is, the longer the time between adjacent impurities is, and the servo system has enough time to remove the impurities, so that the color sorting precision is improved. In the same way, the higher the initial purity of the raw material is, the less the impurity amount is, and the higher the color selection precision is. Meanwhile, the color selection precision is limited by the design of a servo system, when more than two impurities are in the same frame of image, only one impurity can be removed, the color selection precision is reduced, and the adoption of a check structure is better than that of a single-selection structure.
(3) Carry over ratio
The carry-out ratio is the ratio of the quantity of impurities in the waste material selected by the color selector to the quantity of normal materials. The height of the take-out ratio can be adjusted, and the adjustment of the take-out ratio is mainly completed by adjusting the power-on time of an actuator. If the out-of-band ratio is set to be too high, two indexes of the selection rate and the processing capacity are influenced; if the setting is too low, the normal materials contained in the selected waste materials are too much, which causes waste; if the treatment is carried out again, a certain amount of manpower and material resources are required, which causes much trouble and economic loss.
In the actual production process, the three indexes of the processing amount, the color selection precision and the carry-out ratio are integrated and are all key indexes which need to be simultaneously considered. The screening of nut also uses the look selection machine, however, among the prior art, because no matter will take out than setting up too high or low excessively, all influence the accuracy or the efficiency of look selection to manufacturing cost has been improved.
