Description

Technical Field

[0001] This utility model belongs to the field of medical supplies technology, and specifically relates to an air flotation bed that can prevent tail wobble from deviating, and more specifically to an air flotation bed for a high-precision cutting bed device. Background Technology

[0002] Cutting bed devices are used in the production of protective clothing, surgical gowns, and other protective garments to improve production efficiency. These devices include air-floating beds, automatic fabric spreading machines, and automatic cutting beds. The air-floating beds, automatic fabric spreading machines, and automatic cutting beds work together to achieve automatic fabric cutting. The air-floating beds use airflow to make the fabric float, reducing friction and making fabric movement easier and less strenuous. However, in some cutting stages, manual assistance is still required to ensure cutting accuracy. For example, after the fabric is laid on the air-floating bed by the fabric spreading machine, it needs to be manually dragged onto the automatic cutting bed. During this process, the already laid fabric, due to its weight and length (potentially exceeding 20 meters), requires airflow from the air-floating bed to reduce friction. However, this can easily cause the fabric to wobble or sag, requiring multiple people to ensure that the edge of the laid fabric is aligned with the edge of the air-floating bed during dragging. Furthermore, during the cutting process, it is necessary to frequently check whether the fabric is wobble or sag, which is labor-intensive and cumbersome to adjust. In existing technology, fabric clamping devices can be used to prevent fabric wobble.

[0003] For example, patent application number CN201720850599.7 discloses a fabric clamping device on an air-floating tabletop. The air-floating tabletop includes a board body and a long strip-shaped base plate disposed on the board body. A pressure plate is provided above the base plate, and a support column is fixedly provided on the base plate. The support column passes through the pressure plate and is slidably connected to the pressure plate. A spring is sleeved on the support column, and the two ends of the spring act on the upper surface of the pressure plate and the upper end of the support column, respectively. The two ends of the base plate also have limiting bearings that abut against the two sides of the board body.

[0004] Existing technology uses a pressure plate to press the entire front end of the fabric onto a base plate. This has the following problems:

[0005] (1) The operation is complicated. The width of the fabric can reach more than four meters. The back end of the fabric is clamped on the fabric clamping device, which is difficult to operate (such as needing to stand on the air flotation bed or multiple people to operate).

[0006] (2) Clamping is done by springs (there are two in the existing technology), which is troublesome to operate (one end of the longer pressure plate needs to be lifted up, and usually one end needs to be clamped first, and then the other end). Utility Model Content

[0007] To address the aforementioned problems, this utility model provides an air-floating bed that prevents the fabric from veering off course, requiring only the left or right end of the fabric's rear end to be clamped; the V-shaped clamps can both adjust the pressure plate vertically (necessary when clamping the fabric) and press the pressure plate downwards. The technical solution is as follows:

[0008] This utility model embodiment provides an air flotation bed that can prevent tail wobble and deviation, including an air flotation table 1 arranged in the front-to-back direction, a slide 2 slidably arranged on the air flotation table 1, and a fabric clamping structure on the slide 2.
