Self-adaptive wall polishing device

Abstract

The invention provides a self-adaptive wall polishing device comprising a device body. The device body comprises a handle. A handheld part is arranged on the surface of the handle. A polishing mechanism is connected to one end of the handle and comprises a fixed part. The fixed part is of a hollow structure. The end of the handle is connected with the outer side of the fixed part. A polishing discis installed on a second installing plate. The second installing plate is connected with a first installing plate through a third spring. The first installing plate is then connected with a rotary motor through a rotary shaft. Changed pressure acting on the polishing disc due to the change of gripping force is resolved and counteracted by the first spring, flatness of the polishing disc during working is ensured, and thus polishing flatness of a wall is ensured. Meanwhile a second spring sucks a movable piece to the top side of an air vent under the action of negative pressure, thus the firstair hole and the second air hole communicate with outside atmosphere, a dust suction hood can move normally, and normal work of the polishing disc is ensured.

Description

technical field [0001] The invention relates to the technical field of construction engineering equipment, in particular to an adaptive wall grinding device. Background technique [0002] Before the wall body is powder coated or painted, the putty on the wall surface needs to be polished to make the wall surface smooth and flat, thereby ensuring the quality of the wall surface after powder coating or painting. The traditional wall grinding is done by hand. Sanding with different grades of sandpaper is very time-consuming and labor-intensive, and a lot of dust is generated during the grinding process. The dust flies around, which not only seriously affects the health of workers, but also The dust generated also pollutes the environment. Now there are some grinding machines that can automatically absorb dust, which can replace the traditional manual grinding of the wall with sandpaper, so as to achieve the purpose of smoothing, dust-free and protecting the health of workers, ...

AI Technical Summary

Problems solved by technology

[0003] However, the existing wall grinder is prone to differences in the flatness of the wall surface due to the change of the manual grip force during the grinding process, which affects the grinding quality and grinding efficiency.

And the dust collection cover will fit with the raised part around the depression on the wall surface. Under the action of the dust collection device, a negative pressure will be formed in the dust collection cover, and finally the grinder will be adsorbed on the wall under the action of negative pressure. so that it cannot be moved and affects the normal work of the grinder
