Description

An implicit array valve cap cutting machine

technical field

The invention relates to the field of industrial equipment, in particular to a cutting machine for an implicit array valve cap.

Background technique

In the clothing, shoe, home textile 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 the flexible sheet, the cutting machine generally uses the negative pressure adsorption effect generated by the exhaust fan under its platform to adsorb the sheet on the platform. At present, the soft surface material cutting equipment generally adopts an open grid type. There is a semi-closed chamber under the bearing platform, and the grille is covered with air-permeable soft materials such as non-woven fabrics, and the bottom of the chamber is connected with a high-power exhaust fan through a pipeline, and the cutting machine cuts The cutter head can use tools such as laser, wire saw, vibrating knife, etc. This design uses the negative pressure adsorption force to adsorb 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 grille. The cover is tightly covered, which causes air leakage during the adsorption process. Even if the face material can cover the grid cap tightly, the slits generated after the face material is cut will cause air leakage and reduce the negative pressure adsorption effect. The current cutting machine generally divides the air extraction chamber at the lower part of the grid-type cap into a plurality of independent compartments, which are respectively connected with the extraction fan through solenoid valves. During the cutting process, the control system dynamically opens the cutting head according to the current position of the cutting head. A solenoid valve connected to the compartment adjacent to the cutter head under the cap, this method can reduce the air leakage of the cap in the negative pressure adsorption and reduce the power of the exhaust fan, but therefore, hundreds of solenoid valves must be used. It brings disadvantages such as complex control system, high equipment manufacturing and maintenance costs, and high operating noise.

There is also a type of cutting machine design that uses a shade curtain that dynamically opens and closes with the movement of the cutting head. This design reduces the air leakage of the platform during the cutting process to a certain extent, and helps reduce the independence of the lower part of the platform. The number of compartments reduces the power of solenoid valves and exhaust fans, thereby reducing equipment costs, control system complexity, production and operation noise and energy consumption. However, the design of dynamic opening and closing shades still has the disadvantage of complex equipment structure.

In order to solve the above-mentioned shortcomings of the current flexible sheet cutting equipment, a cutting machine with simpler structure, lower manufacturing cost, good negative pressure adsorption effect, low noise, and low energy consumption for production and operation is required.
