Description

Conveying table of cutting machine

Technical Field

The invention relates to the technical field of textile cutting machines, in particular to a conveying table of a cutting machine.

Background

The blanking structure of a cutting machine with the publication number of 'CN 110948565A' in the prior art comprises a first conveying belt arranged on the front side of a worktable of the cutting machine, cut leftover materials and cut pieces are conveyed, a pressing roller arranged above the first conveying belt and a semicircular bulge sleeved on the pressing roller separate the leftover materials and the cut pieces, an adsorption device adsorbs the leftover materials and the cut pieces on the first conveying belt, a motor B drives a winding drum to rotate to wind the leftover materials on the winding drum, the first conveying belt rotates to convey the cut pieces to a supporting plate of the blanking device, if the cut pieces are stacked thickly, a laser correlation type photoelectric switch cannot perform correlation, a control system connected with the laser correlation type photoelectric switch informs the motor A to rotate, the supporting plate descends, the cutting pieces can be conveyed continuously by the first conveying belt conveniently, the device can collect the leftover materials of the cutting machine and can store the cut pieces, the labor cost is reduced, the working efficiency is increased, and a large amount of time is saved for cutting large quantities of cloth materials.

Cloth laser cutting process among above-mentioned device and the prior art goes on netted transfer chain surface usually, through tiling the cloth and netted transfer chain surface to the laser cutting device who utilizes the top to slide the setting carries out cutting of cloth, but the blanking structure of above-mentioned this guillootine still has comparatively obvious defect in the use: 1. because the cloth is usually thin, the reticular conveying line is easily burnt by the focused wire harness in the laser cutting process, so that the service life of the reticular conveying table is shortened, and meanwhile, substances such as slag and the like generated in the high-temperature burning process of the cloth are usually attached to the surface of the reticular conveying line, and the attached substances such as the slag and the like are combined with the cloth at the rear end again in a contact manner, so that the stain of the cloth is caused, and the quality of a finished product is influenced; 2. in the prior art, the fabric cut by laser is easy to cause yellow spot phenomenon on the cut edge, the generation of the yellow spot phenomenon is analyzed to be associated with the smog generated by laser cutting and the incapability of timely overflowing and scattering of cutting high temperature, the conveying mode of the mesh conveying line only adopts an exhaust device arranged at the bottom of the mesh conveying line, the smog generated in the laser cutting process cannot be fully exhausted by a non-targeted exhaust mode, and the exhaust mode has huge air consumption and is usually put into the process but has little effect; 3. adopt the laser cutting device of netted transfer chain mode among the prior art, the leftover bits after cutting can't get rid of voluntarily, can drop from the afterbody of netted transfer chain along with the motion of netted transfer chain usually to cause the piling up of a large amount of leftover bits, need artifical regular cleaning, otherwise will influence off-the-shelf normal rolling.
