[0002] During the sewing process, the presser foot is needed to press the fabric at the sewing position to prevent it from wrinkling when moving and affecting the sewing effect. Existing fabric pressing devices, such as a fabric pressing structure for a computer sewing machine disclosed in application No. CN202322090056.8, use a pressing plate to press down and fix the fabric. When the fabric is moved, the friction force is used to drive the moving belts inside the first pressing plate and the second pressing plate to rotate along the rotating shaft, thereby reducing the friction between the fabric and the pressing plate, improving the convenience and smoothness of movement, and improving the accuracy of the sewing position.

[0003] However, with the development of science and technology, the existing cloth sewing equipment has gradually realized automated production. The above-mentioned cloth pressing device has a single structure, cannot adapt to the execution of multiple sewing mechanisms, cannot adjust the height, and cannot flexibly adjust the pressure applied to the cloth. As a result, it is still easy for the cloth to pass through poorly, especially when pressing cloth of different thicknesses, it is more likely to be blocked. For this reason, we propose a cloth pressing device for cloth sewing to solve the above problems. Utility Model Content
