Description

Array valve bearing platform

Technical field

The invention relates to the field of industrial equipment, in particular to an array valve bearing platform.

Background technique

In clothing, shoemaking, home textiles and other industries, desktop cutting machines are widely used to cut sheet-like flexible materials such as cloth, leather, and fur. In order to ensure the cutting quality of flexible sheets, the cutting machine generally uses the suction effect of the suction fan under the bearing platform to absorb the sheet on the bearing platform. At present, the soft surface material cutting equipment generally adopts an open grid type. The bearing platform is provided with a semi-closed chamber under the bearing platform. At the same time, the grille is covered with a breathable soft material such as non-woven fabric. The bottom of the chamber is connected with a high-power exhaust fan through a pipe. The cutter head can use laser, wire saw, vibrating knife and other tools. This design uses negative pressure adsorption force to absorb the soft surface material on the platform to ensure the cutting quality, but the surface material of different shapes usually cannot be used for the grid The bearing platform is tightly covered, causing air leakage during the adsorption process. Even if the face material can cover the grille platform tightly, the slits produced after the face material is cut will also cause air leakage and reduce the effect of negative pressure adsorption. The current cutting machine generally divides the air extraction chamber at the bottom of the grid-type cap into multiple independent compartments, which are respectively connected to the exhaust fan through a solenoid valve. During the cutting process, the control system is dynamically opened according to the current position of the cutting head The solenoid valve connected to the compartment adjacent to the cutter head under the bearing platform can reduce the leakage of the bearing platform in the negative pressure adsorption and reduce the power of the exhaust fan. However, hundreds of solenoid valves must be used. It brings the disadvantages of complex control system, high equipment manufacturing and maintenance costs, and high operating noise.

In order to solve the above-mentioned shortcomings of the current flexible sheet cutting equipment, it is necessary to design a platform for the desktop cutting machine with a simpler structure, good negative pressure adsorption effect, low manufacturing and use costs, and low operating noise.
