In order to avoid rebound shrinkage of cloth surface under the action of gravity after cloth is cut, as shown in fig. 14, the lifting main board 7 is arranged on the bed surface of the machine tool 1, two ends of the lifting main board 7 are movably connected with movable side boards 8 through shafts, the edges of the movable side boards 8 are provided with pushing structures 9, in addition, a lifting pressing board 10 is arranged on one side close to the cloth feeding frame 2, the pressing board 10 presses against the surface of the cloth and presses the cloth onto one movable side board 8, so that the pulled cloth is attached and fixed on the arched plate surface.
In the invention, the cloth is pulled by the cloth pulling frame 5 in a direction far away from the cloth roller 3 through the clamping piece 6, after the pulling is finished, the movable side plate 8 inwards extrudes the lifting main plate 7 to form a whole arched plate surface, so that the cloth is attached to the plate surface, the cloth on the plate surface is fixed by the pressing plate 10, most of the cloth surface to be sheared is completely fixed, the cloth is sheared, and sheared cloth ends fall on the movable side plate 8 under the action of gravity, thereby greatly reducing the influence of stress release of the cloth on the whole state of the cloth and improving the flatness of the cloth.
Further, the fixing action of the pressing plate 10 is synchronous to position existing cloth pieces on the plate surface, so that the influence of the existing cloth pieces on the cloth piece layers is avoided, and the flush degree of the cloth piece layers is ensured.
In the prior art, the cloth is not only affected by stress release after being cut, but also affected by gravity, under the dual effects of the stress release effect and the gravity effect, the cutting end of the cloth piece instantaneously and rapidly contracts and rebounds to the gravity center position of the cloth piece to form wrinkles, the cloth is fixed in a mode of arching and positioning the cloth, the fixed cloth part is not affected by stress at all, and the stress effect of a small part of the cloth which is not fixed is smaller, specifically, the fixed position height of the cloth on the movable side plate 8 is higher than the position height of the cloth led out from the clamping long plate 4, that is, the cloth is in an inclined upward state from the cutting position to the fixed position on the movable side plate 8.
Assuming that the cloth between the cutting position and the fixed position on the movable side plate 8 is defined as an unfixed cloth area, and the cloth between the fixed position on the movable side plate 8 and the clamping position of the clamping piece 6 is defined as a fixed cloth area, the cloth is completely fixed in the fixed cloth area and is not influenced by stress release and gravity after cutting;
