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 an automatic cutting device used in textile and clothing industry, leather industry, automobile seat industry and furniture industry. In the prior art, a fixed working table of a cutting bed or a cutting machine is improved into a conveyor belt type working table, a conveyor belt is adjusted into a breathable felt, and a negative pressure mechanism capable of forming vacuum is fixed on the lower portion of the felt, so that the effect of fixing a fabric on the surface of the felt is achieved.
The vacuum chamber component and the vacuum adsorption device for the cutting bed, which are provided in the Chinese patent with the publication number of CN202607290U, can solve the deformation problem of the existing cutting bed with a larger breadth, because the flatness of the upper part of the vacuum chamber with the larger breadth is reduced after the vacuum pump is connected with the larger cutting bed, the fabric is cut in the cutting process, but the cutting bed with multiple chambers has the defects that the adsorption force at the joints of the multiple chambers is poor, and the cutting knife has the phenomenon of cutting deviation when the cutting knife moves in the positions;
in the practical process of the cutting bed, the phenomenon that the adsorption effect is deteriorated after the cutting bed is used for a period of time 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 is abraded with equipment in the rotation process to generate micro fibers, so that holes of a lower vacuum cavity are blocked, the adsorption effect of an upper part is influenced, and the fibers sucked into the vacuum cavity also influence the vacuum degree of a vacuum pump;
(2) The fabric is laid on the upper portion of the felt, and the cut fibers can be generated at the cut in the cutting process through material cutting, so that the air permeability of the felt and the adsorption effect are influenced.
Summarizing the reasons, the main reason influencing the adsorption effect of the cutting bed is that the channel forming negative pressure in the adsorption process is blocked, and the adsorption effect of the fabric on the felt is further deteriorated.
In view of the above problems, it is thought that the adsorption effect is ensured by combining electrostatic adsorption and negative pressure adsorption, for example, patent CN216037285U proposes a vacuum negative pressure and electrostatic adsorption composite sucker, which improves the adsorption effect by combining vacuum negative pressure and electrostatic adsorption, but this scheme does not use the step of cutting, and therefore the phenomenon of blocking of air holes rarely occurs, and thus the above problems are not solved at the present stage.
