Abstract

An exposed magnetic transverse bar-driven valve array support table, pertaining to the field of industrial equipment. The table comprises a support table (1), a valve driving module (2), and an air collection pipe (3). The support table (1) is divided into air suction grids by means of a composite structure consisting of a valve block array layer (13) driven magnetically, a grid layer (14), and a non-woven fabric layer (15), and the air suction grids are on or off in a mutually independent manner. When the support table (1) is used as a support table for a tabletop cutter, the valve driving module (2) is provided above the support table (1) and moves along with a cutter head (8), and a magnetically driving transverse bar of the valve driving module (2) that moves along with the cutter head (8) controls air valves (13101) of valve blocks in the support table (1) to be on or off to dynamically communicate valve blocks (131) in a strip-like local region of the support table (1) with an extractor fan (9). The invention limits an effective air suction cross section of the support table (1) to be within a strip-like local region near the cutter head (8), thereby achieving, with a reduced air evacuation power, a negative pressure-based holding effect in the local region of the support table. The exposed magnetic transverse bar-driven valve array support table has advantages of structural simplicity, a low manufacturing cost, a superior negative pressure-based holding effect, low noise, and low power consumption for production and operations.

Description

Explicit magnetic beam drive array valve bearing platform

Technical field

The invention relates to the field of industrial equipment, in particular to an explicit magnetic beam drive 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 tools such as lasers, wire saws, vibrating knives, etc. This invention uses negative pressure adsorption force to absorb the soft surface material on the platform to ensure the cutting quality, but the surface materials of various shapes usually cannot be used for grids. 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 invent a bearing platform for the desktop cutting machine with a simpler structure, good negative pressure adsorption effect, low manufacturing and use costs, and low operating noise.

As the cutter head 8 of the cutting machine moves on the bearing platform 1 according to the set processing trajectory, when the valve drive module 2 moves to a certain position with the cutter head, the bearing platform 1 is located in the belt-shaped area near the cutter head. The ball plug 1311 in the valve block 131 is attracted by the valve drive magnet 22 and moved up to the ball plug seat 13102 to open the valve 13101, where the upper part of the valve block passes through the zigzag air passage inside the valve block, and the valve 13101 on the bottom plate of the valve block and The air-gathering channel at the bottom of the bearing platform is connected. Here, the air flow rate through the bearing platform is the largest. Therefore, the negative pressure adsorption force on the bearing platform 1 is also the largest. The ball plug 1311 resides in the air valve 13101 under the action of gravity to block the air flow channel. As a result, the negative pressure adsorption on the bearing platform 1 is mainly limited to the band-shaped area being cut near the cutter head, so the exhaust fan can be greatly reduced. The exhaust power consumption.
