Automatic mobile cotton bale and cotton sampling device and sampling method thereof

Abstract

The invention relates to an automatic mobile cotton bale and cotton sampling device which comprises a base, a mobile guide track, a station rotation table and a working station table, wherein a cotton packaging material cutting mechanism, a cotton bale bundling material shearing mechanism and a cotton sample grasping mechanism are respectively arranged on the working station table; the cutting mechanism comprises a first guide track; a cutter rotating disc which is connected with a cutter base is arranged on the first guide track; a cutter sliding track matched with a cutter holder is arranged on the cutter base; a cutter is arranged on the cutter holder; the cutting mechanism comprises a second guide track; a scissor rotating disc is arranged on the shearing mechanism; the scissor rotating disc is connected with a scissor base; a pair of cotton bale bundling material scissors is arranged on the scissor base. Due to adoption of a cotton shifting mechanism, cotton, of which fiber is cut off when external packaging is opened, can be shifted off, and cotton, of which fiber is not cut off, can be gasped out from a cotton bale to be detected, so that detection accuracy can be improved, and detection errors can be avoided; and due to adoption of multiple functional mechanisms on the working station table, the whole process of sampling cotton and external cotton packaging can be completed by using one piece of equipment.

Description

technical field [0001] The invention relates to the field of mechanical equipment, in particular to equipment for sampling textile raw materials before inspection, in particular to a movable cotton bale and cotton automatic sampling device and a sampling method thereof. Background technique [0002] my country is the world's largest cotton producer and consumer, as well as the largest cotton importer. According to statistics from the National Bureau of Statistics, my country's domestic cotton production has averaged about 6.5 million tons in the past ten years, totaling about 30 million bales, and about 30 million samples need to be sampled and inspected each year. According to customs statistics, the average amount of imported cotton in my country in the past ten years is about 3 million tons, totaling about 14 million bales, and about 1.4 million samples need to be sampled and inspected each year. Therefore, every year my country's cotton inspection department needs to sa...

Problems solved by technology

However, cutting and sampling with a circular cutting knife does not comply with the cotton sampling method for import and export of Appendix C on pages 11-13 of the standard SN / T 3702.2. Cut off, causing inspection error

On the other hand, according to the requirements of the standard GB 6975 "Cotton Packaging", in addition to the cotton in the bale that needs to be sampled and tested, the cotton outer packaging materials (such as white cotton cloth, cotton gauze and polyester plastic bags, etc.), and cotton bale binding materials (Steel wire or polyester strapping) is also a range that needs to be sampled and tested, but samples of cotton packaging materials and cotton bale strapping materials cannot be obtained at the same time through the above-mentioned prior patents, and re-sampling is required

What is even more unfavorable is that the equipment described in the above-mentioned prior patent is a fixed and non-movable device, which cannot meet the flexible sampling requirements under different storage conditions
