[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0020] The utility model provides a circular cloth pressing and cutting mechanism.

[0021] In this embodiment, refer to Figure 1-3The circular cloth pressing and cutting mechanism comprises a support foot 1, a vertical plate 2 fixed on the support foot 1, a driven roller shaft 3 arranged on the support foot, and an active roller shaft assembly arranged above the driven roller shaft, wherein the active roller shaft assembly comprises an active roller shaft 4, a connecting screw rod 5, and a bearing plate 7 rotatably connected to a connecting shaft 6 at both ends of the active roller shaft through a bearing, one end of the connecting screw rod 5 passes through the vertical plate and is threadedly connected to an upper nut 8, and the other end passes through a through hole on the bearing plate 7 and is threadedly connected to a lower nut 9, and a plurality of circular cutters 10 are arranged on the surface of the active roller shaft.
