Problems solved by technology
The honeycomb material has the characteristics of convenient use, pressure resistance, and easy flattening of the platform in the later stage. However, because the honeycomb material is difficult to carry out specific processing, it cannot construct a reasonable gas flow channel inside the platform, so its overall permeability is low, resulting in the surface of the platform. The adsorption force is extremely uneven, and a high-power air pump is required to ensure that the adsorption force on the surface of the platform meets the working requirements

The invention relates to the field of adsorption platforms in material processing, in particular to a controllable vacuum adsorption platform. The controllable vacuum adsorption platform comprises a base, a honeycomb support layer and a panel, wherein an air suction hole is formed in the base, the honeycomb supporting layer is arranged on the base, and a plurality of air suction holes are formed in the panel. The controllable vacuum adsorption platform further comprises a pressure equalizing chamber arranged between the honeycomb supporting layer and the panel, a vent hole connected with the air suction hole is formed in the pressure equalizing chamber, the pressure equalizing chamber is provided with a plurality of supporting structures, and the supporting structures are used for supporting the panel. According to the controllable vacuum adsorption platform, when the air suction hole are connected with an air pump, the vent hole in the pressure equalizing cavity are directly connectedwith the air pump through the air suction hole, so that the pressure loss is reduced, enough negative pressure intensity is ensured in the pressure equalizing chamber, and the power requirement of the air pump is low; and the overall ventilation performance of the platform is good, and the negative pressure is uniform everywhere in the pressure equalizing cavity, so that the controllability and the uniformity of the adsorption force of the adsorption platform are ensured through reasonably making openings on the panel.
Description
technical field [0001] The invention relates to the field of adsorption platforms in material processing, in particular to a controllable vacuum adsorption platform. Background technique [0002] When materials such as leather and cloth are processed manually or mechanically in the factory, a platform is needed to fix the materials to facilitate cutting and other processing. A commonly used platform is the vacuum adsorption platform. The vacuum adsorption platform is mainly composed of panels, bases, and honeycomb materials. The base is filled with honeycomb material as a honeycomb support layer, and the base is provided with suction holes, and the upper part of the base is covered with a panel with suction holes, and the entire platform is flattened and sealed. Afterwards, the air pump pumps the platform through the suction holes, so that the suction holes on the surface of the panel generate adsorption force and fix the materials to be processed. [0003] At present, th...
