Description

Multi-purpose array valve bearing platform cutting machine

Technical field

The invention relates to the field of industrial equipment, in particular to a multi-purpose array valve bearing platform cutting machine.

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.

The working process of the equipment is as follows:

Referring to Figures 1A-6A, during the production operation, the flexible surface material 100 is spread flat on the platform 2 to start the cutting process.

At this time, the valve drive electromagnet 702 is energized, and the valve drive armature 704 is subjected to electromagnetic force, so that the valve drive core tube 703 overcomes the resistance of the return spring 705 and moves downward under the action of the electromagnetic force, so that the valve drive magnet 708 approaches the bearing platform 2. The ball plugs 2114 in the valve blocks 211 in the bearing platform below the valve drive magnet 708 are attracted by the magnetic force and lifted to the ball plug seat 2111 to open the valve 2113.

Blocking the air flow channel, as a result, the negative pressure adsorption on the bearing platform 2 is mainly limited to the block area being cut near the cutter head, so the exhaust power consumption of the exhaust fan can be greatly reduced.

After production, the valve drive electromagnet 702 is de-energized, the electromagnetic force received by the valve drive armature 704 disappears, and the valve drive core tube 703 is lifted under the action of the return spring 705 to make the valve drive magnet 708 separate from the platform 2, below the platform The magnetic force received by the ball plug 2114 in the valve block 211 disappears and falls into the ball plug seat 2111 of the valve block under the action of gravity, thereby closing the valve 2113.

The working process of the equipment is as follows:

Referring to Figures 1C-7C, during the production operation, the flexible surface material 100 is spread flat on the platform 2 to start the cutting process. At this time, the exhaust fan 8 also starts to draw air, and the air above the bearing platform 2 is sucked into the air collecting channel 25 at the bottom of the bearing platform 2 through the surface material 100, the non-woven fabric 23, the grille 22, and the valve block array layer 21 and collected into the air collecting pipe. 24, it is drawn away by the exhaust fan 8, so that a negative pressure is generated between the face material 100 and the platform 2 and the face material is adsorbed and attached to the platform 2 to prevent the face material from moving during the cutting process. As the cutter head 6 moves on the bearing platform 2 according to the designed processing trajectory, the X-axis drive module and the Y-axis drive module 5 drive the valve drive module 7 through the X-axis threaded slider 37 and the Z-axis drive rod 712 respectively. The valve drive magnet 708 follows the current position of the cutter head 6 in real time. When the valve drive magnet 708 of the valve drive module 7 moves to a certain position with the cutter head, the ball plug 2114 in the valve block 211 near the cutter head in the bearing platform 2 is attracted by the valve drive magnet 708 and leaves the valve lock magnetic ring. 2115 restrains and falls into the ball blocking seat 2111 to open the valve 2113. Here, the upper part of the valve block communicates with the air collection channel 25 through the valve 2113 and the vent 2112. Here, the air flow rate through the bearing platform is the largest, so the bearing platform 2 The negative pressure adsorption force of the block-shaped local area near the cutter head is also the largest, and the ball plug 2114 in the valve block 211 far from the cutter head 6 in the bearing platform 2 is kept in the valve 2113 under the magnetic constraint of the valve magnetic ring 2115. The air flow channel is blocked. As a result, the negative pressure adsorption on the bearing platform 2 is mainly limited to the block area being cut near the cutter head, so the exhaust power consumption of the exhaust fan can be greatly reduced.
