What is the working principle and specific function of the wall grinder?

Machines for grinding walls are collectively referred to as wall grinders, also known as wall grinders, wall grinders, putty grinders, wall grinders, white grinders, vacuum grinders, sanders, and sandpaper machines. The standard names vary from place to place.

The invention is a new patent [1] applied by Ni Yuping, and discloses a grinder, which comprises a dust removal loading and dust removal device, wherein the dust removal device comprises a shell, a dust removal motor, a dust removal protective cover and a working disk. The utility model separates the dust removal device from the dust collection device, and the dust removal device and the dust collection device are connected through a dust collection connecting pipe; A dust collecting pipe is arranged on the dust collecting hood, and one end of the dust collecting pipe is connected with a dust collecting connecting pipe. The split mechanism can not only suck dust into the dust collection device as much as possible, so as to avoid the harm of dust to human body to the greatest extent, but also absorb a large amount of dust at one time, so as to avoid reducing the working efficiency due to frequent replacement of dust collection bags. Therefore, the utility model is used for polishing walls, boards or floors, which is not only environmentally friendly and sanitary, but also can improve the working efficiency.

The product will be described in further detail with reference to the attached drawings:

As shown in the figure, the grinding machine includes a dust removal device and a dust suction device, wherein the dust removal device includes a shell 1, a dust removal motor 6, a dust exhaust cover 9 and a working disk 10, and the dust removal device and the dust suction device are separated and connected through a dust suction connecting pipe 13; The dust collecting hood 9 is provided with a dust collecting pipe 12, and the dust collecting pipe 12 is connected with one end of a dust collecting connecting pipe 13.

As shown in the attached figure, the dust suction device is that the dust suction port of the dust suction fan 16 is connected with the outlet end of the dust suction connecting pipe 13, and the dust outlet of the dust suction fan 16 is connected with the dust mobile phone bag 18.

The dust fan 16 and the dust bag 18 are all put in the backpack 15. It is beneficial for workers to move by the way.

Vacuum connection pipe 13 hose.

The reduction gear set 3 is installed between the dust removal motor 6 and the dust removal cover 9. As shown in the attached figure, the reduction gear set 3 is realized according to the general technology; After the pinion drives the big gear to rotate twice, the rotating speed of the rotating shaft that drives the action disk to rotate is much lower.

Dust removal motor 6-position variable speed motor. The user can adjust the rotating speed of the working disk according to the actual situation.

When working, the rotating shaft 2 of the dust removal motor 6 rotates under the support of the bearing 5, driving the cooling fan 8 to rotate, so as to achieve the purpose of cooling. After the rotating shaft 2 reduces the rotating speed through the reduction gear set 3, it drives the working disk 10 to rotate, thus achieving the purpose of polishing. The function of the damping disc 1 1 is to reduce the vibration amplitude of the working disc 10.

The structure of the split wall grinder can not only suck dust into the dust suction device as much as possible, so as to avoid the harm of dust to human body to the greatest extent, but also suck a large amount of dust at one time, so as to avoid reducing the working efficiency due to frequent replacement of the dust suction belt18; In addition, due to the function of the reduction gear set 3, a high-efficiency and high-power dust removal motor 6 can be selected to achieve the effect of a high-power motor, so that the cost can be reduced, the weight of the whole dust removal device can be reduced, the service life of the motor 6 can be prolonged, and the stability of the working disk 10 can be enhanced.

The invention greatly saves manpower and material resources, greatly improves the working efficiency and reduces the inherent cost. The use of wall grinder is also an important reference standard to identify a good decoration team, and it is a special tool for paint workers. The effect of polishing the wall surface is smooth, smooth and delicate, and the effect is the same in a large area. By using sandpaper with different particle sizes, the automobile surface effect can be achieved. When the product is running, the dust is basically absorbed by its vacuum cleaner, which solves the pollution of dust flying in the air to the environment, protects the health of workers, and the site construction environment is very clean.
