Embodiment Construction
[0033] The present invention is described in further detail below in conjunction with accompanying drawing:
[0034] Such as figure 1 As shown, this is the high-speed and high-precision automatic weighing equipment described in the invention, including a feeding section 1, a positive position mechanism 2, a weighing section 3, an electric control cabinet 4, a windshield 5, a rejecting nozzle 6, a rejecting section 7 and waste collection box 8.
[0035] figure 1 Based on the overall structure of the high-speed checkweigher, it mainly includes feeding section 1, alignment mechanism 2, weighing section 3, electric control cabinet 4, windshield 5, rejecting nozzle 6, rejecting section 7 and waste collection box 8. Among them, the feeding section 1, weighing section 3 and rejecting section 7 are installed side by side at the same height in turn, and the table top is guaranteed to be level. The feeding section 1, weighing section 3 and rejecting section 7 all adopt belt conveyors;...

The invention discloses an automatic weight checking and screening device and method. The automatic weight checking and screening device comprises a rack, a feeding section, a weighing section and a removing section. The feeding section, the weighing section and the removing section are sequentially arranged on the rack side by side and all adopt belt conveying devices. A removing device is arranged on one side of the removing section and located above the removing section, according to the removing device and the removing section, and the output direction of the removing device is parallel to the horizontal plane and perpendicular to the conveying direction of the removing section. A weighing sensor is arranged at the bottom of the weighing section. The output end of the weighing sensor is connected with the input end of a comparator, the output end of the comparator is connected with the input end of a delayer, and the output end of the comparator is connected with the removing device. Materials which do not meet the weight requirement are automatically removed from a production line, the problems caused by manual sorting are avoided, and the product quality and the additional value are improved.
Description
technical field [0001] The invention belongs to the field of automatic detection equipment, and relates to an automatic weighing and screening device and method. Background technique [0002] Checkweighing equipment, that is, to detect the weight of specified items, is mainly used in packaging production lines in pharmaceutical, food, electronics, daily chemical, light industry, tobacco and other industries. Its main function is to check the weight of the products in the high-speed production line and during the conveying process. When it is found that there are materials that do not meet the weight requirements, they will be manually removed from the production line, or the products will be classified into the corresponding weight class product collectors. The sorting will have the problems of low efficiency, high manual labor intensity, and low pass rate of manual sorting. Contents of the invention [0003] The purpose of the present invention is to overcome the above-m...
