Description

Technical Field

[0001] The utility model relates to the technical field of cross-cutting machines, in particular to a downward pressing and leveling device of a laser cross-cutting and laminating integrated machine. Background Art

[0002] During the production process of dust-free cloth, according to the needs of users, the dust-free cloth needs to be cut into small pieces for the convenience of users. In the process of cutting the dust-free cloth, a cross-cutting machine is used to cut small dust-free cloth pieces.

[0003] Because dust-free cloth is a flexible material and tension is released during cutting, it wrinkles easily. In continuous operation, wrinkled sheets cannot be stacked, making manual handling very troublesome. Furthermore, static electricity prevents the cloth from falling off the cross-cutting machine, leading to a large accumulation of dust-free cloth, affecting the efficiency of the entire cross-cutting machine.

[0004] Existing patent publication number: CN 114000336 B, discloses a material discharge structure for a dust-free cloth cross-cutting machine, comprising a frame, a material pressing mechanism, a material cutting mechanism, a material pulling mechanism, and a support platform. The material pressing mechanism includes a fixed clamping plate, a movable clamping plate capable of rising and falling relative to the fixed clamping plate, and a first drive component that drives the movable clamping plate up and down. The material pulling mechanism includes a first movable component mounted on the frame, a fixed plate driven by the first movable component to move back and forth along the feeding direction, and a material pulling assembly mounted on the fixed plate. The material pulling assembly includes a clamping unit and a material discharge unit. The clamping unit includes a fixed clamping bar, a movable clamping bar positioned above the fixed clamping bar, and a third drive component that drives the movable clamping bar to move toward or away from the fixed clamping bar. The material discharge unit includes a swing block for fixing the clamping unit and a fourth drive component mounted on the fixed plate that drives the swing block to swing. This material discharge structure allows the cut sheets to be stacked more neatly on the support platform, avoiding clutter and facilitating collection.

[0005] However, in the prior art, the dust-free cloth is simply stacked neatly on the drag table. Since the dust-free cloth is a flexible material, and due to the effect of static electricity, the stacked dust-free cloth is very fluffy and uneven. On the other hand, the cutting mechanism works for a long time, which will cause the temperature of the cutting head to rise, posing a safety hazard. Utility Model Content
