[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The present invention sets a follow-up positioning adsorption structure, in which the ferromagnetic plate and the magnetic plate are magnetically attracted to each other, and the movable guide rail moves back and forth along the two sides of the table through the slide rail, and the head moves back and forth at the top of the movable guide rail. While moving, the vibrating knife at the bottom of the head drives the magnetic plate to move accordingly, so that the ferromagnetic plate drives the follow-up positioning adsorption structure to move at the bottom of the table, and the air pump inside the follow-up positioning adsorption structure sucks air to generate negative pressure. The generated negative pressure partially fixes the position of the leather surface currently being cut and adsorbs it on the work table, thereby enhancing stability and preventing movement and slipping at the cutting point during cutting. At the same time, it avoids fixing the leather over a large area and consuming too many resources.

[0018] 2. The present invention sets a heat dissipation structure, and the cooling bag inside the heat dissipation structure is filled with water through the water inlet pipe and the water outlet pipe, so as to form a water circuit, so that the cooling bag can be cooled down quickly. After cooling down, the cooling bag absorbs the heat transferred from the ferromagnetic plate to cool down the leather at the cutting part, so as to avoid the leather being damaged by excessive temperature at the cutting part due to stamping.

[0019] 3. The present invention sets a bottom plate, and sets a weight sensor on the top of the bottom plate. After the front leather is cut, one end of the leather is slowly pulled, and the leather that has been cut will fall into the inside of the collection frame in turn. The screen will screen the cut leather uppers and drop them from the discharge trough at the bottom of the collection frame onto the load-bearing plate for weighing. The weighing data is processed by the controller and transmitted to the counting display. When the weight of the weighing is less than the standard amount, it is recorded as 1. When the count is too high after the device performs a certain number of cuttings, it means that the device needs to be repaired to determine whether there is a problem with the typesetting.
