Detailed Description
As shown in fig. 1-2, the application of the color selector to the production line for cleaning cotton linters comprises: firstly, primarily processing cotton linters by a linter cleaning machine; step two, dividing the cotton linters in the step above into lint blocks with uniform size through a clearing machine; thirdly, screening and classifying the pile blocks in the last step by a color selector, and conveying the screened foreign matters to various foreign matter collecting vehicles; and step four, the qualified pile blocks in the step four are conveyed to an aggregate dust cage, and then packaged by a packaging machine to form a finished product. Color sorters are commonly used in textile industries, where they are used to screen cotton. The color selector solves the problem of picking cotton linters and picks various foreign matters carried in the cotton linters as much as possible, thereby improving the product quality. Before selection, the subsequent identification and selection are facilitated through lint cleaning and blocking.
The problems of easy fatigue of workers and different work responsibility centers are solved, and the problem of difference of the product quality of the white class and the night class is solved. The labor is reduced, and the influence on the workshop yield caused by the time when the personnel please leave is reduced. In particular, the colourless plastic film can be sorted out.
The color sorter comprises a computer, an image system, a storage bin, a detector component and an injection separation execution component, wherein logic analysis control software is loaded on the computer. The pile blocks are in the storage bin and fall along the path, the pile blocks are firstly identified by the detection element assembly on the path, the signal information is transmitted to the image system and the computer for processing, and then the pile blocks are sprayed by the spraying separation execution assembly to fall into the corresponding storage bin.
The jet separation executing assembly comprises an automatic air blowing electromagnetic valve and a transverse air blowing pipe, and the color selector leads high-pressure air into the transverse air blowing pipe through the automatic air blowing electromagnetic valve to blow out foreign matters. The automatic blowing electromagnetic valve is used for controlling the on-off of blowing, the horizontal blowing pipes are transversely or horizontally arranged pipelines, a plurality of openings are arranged on the horizontal blowing pipes along the extending direction of the pipelines, and the openings are mutually separated. The automatic air blowing solenoid valve is a mature technical product and is not explained or limited too much.
The image system precision is adjusted through the processing amount, the color selection precision and the carry-over ratio. 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 also 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 adopted check structure is better than the single-selection structure. 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. 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 sent 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 amount per unit time is closely related to the required selection precision.
The color selector at least comprises a fluorescent substance module, a colored fiber foreign body module and a colorless plastic film module. At least three main foreign matters influencing the product quality are contained, and the picking quality is obviously prompted.
The color selector blows out the foreign matters through the automatic air blowing electromagnetic valve, and blows out the foreign matters through high-speed airflow after the selection is finished. It should be noted that the segmented fluff blocks are relatively flat and discrete for ease of picking.
The automatic air blowing electromagnetic valve supplies air through the air compressor, auxiliary equipment such as a nitrogen cylinder is not needed, the environment is protected, the efficiency is high, and meanwhile, the cost is further reduced.
The invention has the beneficial effects that: the application of the color selector in the production line for cleaning cotton linters enables the picking rate of colored thread ends, fluorescent substances and plastic films in improved products to reach 95% through detection, and especially colorless plastic films which cannot be found in manual picking are picked by the color selector. The quality is stable and meets the requirement after being used by a cotton pulp production line. Moreover, the number of picking personnel is greatly reduced, the cost is reduced, the product quality is stable, and the economic benefit is obvious.
