Description
Technical Field
The invention relates to the technical field of cutting beds, in particular to an anti-blocking cutting bed.
Background
The cutting bed is automatic cutting equipment used in textile clothing, leather industry, automobile seat and furniture industry. In the prior art, a fixed working table of a cutting bed or a cutting machine is improved to be a conveyer belt type working table, a conveyer belt is adjusted to be a ventilated felt, and a negative pressure mechanism capable of forming vacuum is fixed at the lower part of the felt, so that the effect of fixing fabrics on the surface of the felt is achieved.
As a vacuum chamber component and a vacuum adsorption device for a cutting bed are proposed in Chinese patent with publication number of CN202607290U, the deformation problem of the existing cutting bed with a large width can be solved, as the flatness of the upper part of the vacuum chamber with the large width can be poor after the cutting bed is connected with a vacuum pump, the problem of cutting the fabric in the cutting process can be solved, but the cutting bed with multiple chambers can be found when in use, the adsorption force of the connecting parts of the multiple chambers is poor, and the phenomenon of cutting deviation can occur when the cutting knife moves at the positions;
in the practical process of the cutting bed, the phenomenon that the adsorption effect is poor after a period of use often occurs, and the reason for the phenomenon is as follows:
(1) In the long-term use process of the cutting bed, on one hand, the lower surface of the felt and equipment are worn in the rotation process to generate micro fibers, so that holes of a lower vacuum cavity are blocked to influence the upper adsorption effect, and the fibers sucked into the vacuum cavity also influence the vacuum degree of the vacuum pump;
(2) The fabric is laid on the upper portion of the felt, and through material cutting, cut fibers can appear at the cutting edge in the cutting process, and the fibers also influence the air permeability of the felt and influence the adsorption effect.
In summary, the main reason for influencing the adsorption effect of the cutting bed is that the channel forming negative pressure in the adsorption process is blocked, so that the adsorption effect of the fabric on the felt is poor.
In view of the above problems, it is conceivable to combine electrostatic adsorption with negative pressure adsorption to ensure the adsorption effect, for example, a vacuum negative pressure and electrostatic adsorption composite chuck is proposed in the patent with publication No. CN216037285U, and the adsorption effect is improved by combining vacuum negative pressure with electrostatic adsorption, but this solution does not use a step of cutting, and thus the phenomenon that air holes are blocked is rarely occurred, so the above problems are not solved at the present stage.
