Description

TECHNICAL FIELD

[0001] The utility model relates to a cutting bed for fabric cutting belongs to mechanical equipment field. BACKGROUND

[0002] Structurally dense fabric is a type of textile fabric with a tight structure, usually woven from high-density fibers. The advantages of this fabric include excellent durability, moisture resistance, warmth retention, and appearance quality. Structurally dense fabric is commonly used to make high-end clothing, outdoor gear, automotive interiors, and other areas requiring high quality and performance.

[0003] Due to the outstanding advantages of structurally dense fabric, it is now used as down jacket fabric. When used as clothing fabric, the fabric usually needs to be laid out in multiple layers, and then put on the sample, cut according to the clothing style design.

[0004] However, due to the air-tightness of structurally dense fabric, when the fabric is laid out in multiple layers from the roll, there will be air between the layers. If cutting is done directly, it will cause displacement between the fabric layers, resulting in inconsistent cutting, affecting subsequent production.

[0005] Therefore, for structurally dense fabric, after laying out, a layer of plastic film needs to be covered on the surface, and then a cutting machine such as Chinese patent CN212335622U is used to vacuum the space inside the plastic film to remove the air between the fabric layers, making the fabric adhere together, and then cutting.

[0006] However, due to the long length of the fabric cutting table in industrial production, it is difficult to completely remove the air between the fabric layers by vacuuming from both ends. Accordingly, the cutting bed with cloth pressing and film covering structure and cutting bed of Chinese patent CN113638213A uses a roller pressing device to roll the air between the fabric layers, cutting while rolling to prevent relative sliding between the fabric during cutting and stabilize the cutting quality. However, rolling to drive air will itself cause the fabric to slide, resulting in movement of the remaining fabric; and the fabric cutting is not a single-channel linear motion, but often reciprocating in an area. However, when the roller rolls on the already cut piece, it will cause the piece to be misaligned, even moving into the uncut area, causing damage to the piece.

[0007] However, the above method still has the problem of incomplete air removal in the actual cutting process of structurally dense fabric, causing relative sliding between the fabric layers and affecting the cutting quality.

[0008] Therefore, it is necessary to improve the air exhausting method for the cutting of the multi-layer structure intensive fabric, so that the air between the fabric layers is fully exhausted, and the cutting quality of the fabric is improved. Utility model content

[0036] When the fabric is laid out in multiple layers and placed on the cutting table, the existing method involves arranging the fabric according to the shape of the cut piece A of the same material to form a layout diagram, which is then laid out onto the cutting table, projected onto the fabric stack, and then cut. The purpose of this invention is to provide a cutting table capable of drilling holes for ventilation in densely structured multi-layered fabrics, such as... Figure 2 As shown, the cutting platform 1 is equipped with a horizontally movable gantry frame 21, and the gantry frame 21 is equipped with a vertically movable machine head 22.

A drill bit 31 is installed at the bottom of the drilling device 3. According to the pattern of the cut pieces, holes are drilled in the gaps of the cut pieces A, thereby forming a number of ventilation holes B on the fabric. Then, a film is applied, and air is sucked into the multi-layered, densely packed fabric stack inside the film. The air between the fabrics can be discharged through the ventilation holes B, thereby making the layers of fabric in the fabric stack fully adhered and reducing the presence of air. Then, the cutting device 23 of the machine head 22 is started to cut according to the pattern of the cut pieces to form the required cut pieces A.
