Description

Technical Field

[0001] This utility model relates to the field of spinning technology, and in particular to a height-adjustable spinning material rack. Background Technology

[0002] In the chemical fiber spinning production process, spinning racks (or yarn cake / yarn tube placement racks) are a basic and widely used auxiliary equipment. Their core function is to provide temporary storage and positioning support for unwound raw material yarn cakes or empty / full yarn tubes before and after the spinning and winding process. Typical existing spinning racks mostly adopt a fixed frame structure, usually welded or assembled from metal tubing (such as stainless steel or carbon steel) to form multi-layer, multi-row open shelving space. Their design mainly focuses on structural stability, load-bearing capacity, and space utilization to ensure that yarn cakes or yarn tubes can be placed safely and orderly vertically or horizontally for easy identification, turnover, and basic protection. This type of rack structure is relatively simple, with low manufacturing and maintenance costs, and is a common workstation configuration in traditional spinning workshops.

[0003] However, traditional spinning material racks have significant limitations, mainly in their simple structure and single function. The most prominent problem is that the height at which raw materials are placed is usually fixed. The position of each shelf in the rack is determined during design and installation, and cannot be flexibly adjusted according to the height differences of operators, operating habits, or specific process requirements. This directly leads to workers having to frequently bend over, tiptoe, or adjust their posture to adapt to different shelf heights when picking up and placing raw materials. This repetitive, unnatural posture operation is not only time-consuming and laborious, but also greatly increases the labor intensity and fatigue of workers, and can easily lead to musculoskeletal strain in the long run. More importantly, it seriously affects the efficiency of picking up and placing materials, slows down the turnover speed of yarn cakes / tubes between machines, and becomes a bottleneck that restricts the overall efficiency improvement of spinning production lines and hinders the upgrading to automation / semi-automation.

[0004] Therefore, it is necessary to propose a height-adjustable spinning rack to solve the above problems. Utility Model Content

[0005] The main objective of this invention is to provide a height-adjustable spinning rack, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A height-adjustable spinning material rack includes a rack body, in which a support assembly for supporting raw materials is disposed.
