Description

Technical Field

[0001] The utility model relates to the technical field of packaging compression equipment, in particular to a pressing plate locking mechanism and a sample cotton packaging machine comprising the same. Background Art

[0002] Sample cotton is a cotton sample that is randomly selected from each batch of cotton samples and temporarily stored in accordance with regulations after the inspection is completed as stipulated in the cotton inspection regulations. Sample cotton needs to be stored in the sample storage warehouse for at least 30 days so that the higher-level regulatory authorities can conduct quality spot checks at any time, or for re-inspection when quality disputes occur after the cotton enters the market circulation field.

[0003] In December 2022, [Zhongxianfa] Cotton Inspection Procedure No. 46 changed the requirement of taking 10% samples from each batch of cotton inspected before December 2022 to taking 30% samples from each batch of cotton inspected. As a result, medium and large-scale cotton public inspection laboratories (annual public inspection volume of more than 300,000 tons) with the characteristics of productive testing are facing a serious shortage of storage capacity and the dilemma of building or expanding sample storage. Efficient compression storage is the optimal solution to this problem. In addition, the comprehensive quality of front-line operators in production varies greatly. In the past, simple compression packaging machines had more human intervention links in the operation process, which caused the quality of compressed packaging of sample cotton to fluctuate greatly.

[0004] The utility model is an important part of the sample cotton compression packaging machine. In the previous technology, after the sample cotton is compressed, the operator needs to manually insert the locking rod above the pressing plate with the help of a special tool. After the sample cotton is compressed and the pressing plate is locked, the cover is opened and the lock is buckled, and the locking rods need to be manually pulled out one by one with the help of a special tool. When the locking rod is manually pulled out, since the pressing mechanism has returned to reset, the rebound pressure of the compressed cotton sample is relatively large, so that the pressing plate and the locking rod are tightly in contact with each other, it is difficult to pull out the pressing rod, the labor intensity is relatively large, and the insertion and extraction efficiency is low.
