Description

Technical Field

[0001] The invention relates to the technical field of spraying equipment, in particular to surface spraying equipment for aluminum veneer processing. Background Art

[0002] As a lightweight and corrosion-resistant building material, aluminum veneer is widely used in building curtain walls, interior decoration and other fields. Surface spraying can not only improve its aesthetics, but also enhance its weather resistance and corrosion resistance. With the market demand and technological progress, aluminum veneer surface spraying equipment continues to develop and become a key link in aluminum veneer production. However, there are still some problems in the use of existing spraying equipment, as follows: The existing spraying equipment has a good spraying effect on aluminum plates with smooth surfaces, but the spraying of aluminum plates with a certain curvature on the surface will rely heavily on image acquisition and generation technology, and combined with the continuous adjustment of the control nozzle under the driving mechanism to achieve spraying on the curved surface. However, this method will cause the entire equipment to be overly dependent on the effect of the imaging structure and requires a complex control system to achieve it. The equipment nozzle cannot automatically adjust the distance of the nozzle during mobile spraying according to the curved surface of the aluminum plate on the placement platform, and thus cannot achieve the effect of adaptive uniform spraying. The overall applicability of the equipment is poor. For this reason, we propose a surface spraying equipment for aluminum veneer processing. Summary of the invention

[0027] Working principle: Place the aluminum plate on the top of the supporting top rod 23. The aluminum plate will press down the supporting top rod 23 under its own weight, thereby stretching the first spring 25 inside and compressing the inner airbag 22 at the same time. After the gas in the inner airbag 22 is compressed, it will enter the interior of the air intake cylinder 51 through the air guide hose and inflate the driven airbag therein, thereby driving the first permanent magnet block 52 at the bottom to adjust the corresponding position. The greater the curvature of the corresponding position of the aluminum plate, the greater the compression of the inner airbag 22, and the longer the downward movement of the first permanent magnet block 52 at the corresponding position, combined with the second permanent magnet block 7 set in the middle 2 automatically forms a shape relatively continuous with the first permanent magnet blocks 52 on both sides under the support of the elastic rope 54, so that when the connecting cantilever 112 is driven to move by the linear motor structure 10, the magnetic repulsion between the third permanent magnet block 114 and the first permanent magnet block 52 and the second permanent magnet block 72 is used to automatically drive the nozzle 117 to move down a corresponding distance, so that during the movement and spraying process of the nozzle 117, the corresponding distance can be automatically adaptively adjusted according to the surface downward pressure of the aluminum plate, which greatly improves the convenience of use of the device, simplifies the use operation and also ensures the spraying effect of the device.
