Description

Technical Field

[0001] The utility model belongs to the field of sewing, and in particular relates to a cloth pressing piece, a cloth pressing device and a bag opening machine. Background Art

[0002] The bag opening machine is a device that is often used in the field of sewing. It is mainly used to form a bag opening at a specific position of the cloth. In the process of forming the bag opening, the bag opening machine first needs to cut at a specific position of the cloth to form a Y-shaped cutting line at both ends, and then fold the folded edge at the cutting line to form a rectangular opening. The rectangular opening is then sewn and other steps are performed to form the bag opening of the garment.

[0003] In the process of the bag opening machine, in order to prevent the cloth from moving and misaligning, a cloth pressing device is needed to fix the cloth and ensure that the cloth remains stable. In the prior art, CN202020675348.1 discloses a material fixing mechanism, which mainly fixes the cloth by pressing down a pressing frame.

[0004] However, the pressing frame used to fix the cloth in the prior art has some shortcomings, mainly reflected in that when the pressing frame presses down to fix the cloth, since the pressing frame is of fixed size, the pressing frame can only press the fixed position each time. However, in different usage scenarios, the opening size of the bag opener structure is different. Therefore, when the opening size changes, the pressing frame that can only press the fixed position will not be able to adapt. For example: when the opening size is too large, the pressing frame may hinder the bag opener from operating the opening; when the opening size is too small, the pressing frame may not be able to press the cloth at the opening.

[0005] In summary, the pressing frame for fixing the cloth in the prior art has the problem of being unable to adapt to openings of different sizes. Utility Model Content

[0006] The utility model provides a cloth pressing piece, a cloth pressing device and a bag opening machine, which aim to solve the problem that a conventional pressing frame cannot be adapted to openings of different sizes.
