Description

Technical Field

[0001] The present invention relates to a hydraulic compression device and method for clothes, belonging to the technical field of the design of clothes compression devices. Background Art

[0002] Driven by the continuous growth of the global economy and the increasing diversification of consumer demands, the clothing logistics industry is undergoing profound changes like never before. With the booming development of e-commerce and consumers' eager anticipation of fast delivery, logistics efficiency has become one of the core elements of enterprise competition. Before placing clothes in a packaging bag, it is necessary to compress the folded clothes and then put them into the packaging bag. However, when dealing with thick clothes (such as cotton-padded clothes and down jackets), the traditional manual compression method gradually reveals many obvious shortcomings. During the operation, workers need to repeatedly fold and compress the fluffy clothes. This process is not only time-consuming and laborious but also likely to result in uneven packaging quality due to individual operation differences, thus seriously affecting logistics efficiency. Prolonged engagement in high-intensity repetitive labor will not only exacerbate workers' physical fatigue but also may cause occupational health problems such as muscle strain and joint injuries, further affecting operation efficiency and personnel stability. Therefore, there is an urgent need for a device that can replace manual labor to compress clothes, so as to improve the overall operation efficiency, ensure personnel health, and promote the high-quality development of the clothing logistics industry.
