Wall grinder: a tool that replaces the traditional manual grinding of walls and objects with sandpaper to achieve the purpose of making it smooth, dust-free, and protecting the physical and mental health of workers.
Optimize the working environment, improve work efficiency, and improve the quality of decoration.
Introduction Catalog Introduction to wall sanders
Machines that polish walls are collectively called wall sanders, which can also be called "vacuum sanders" and "dust-free sanders". "machine", "wall grinder", "wall sander", "putty grinder", "
wall grinder", "polishing machine", "Dabai grinder", "dust-free grinder" ", "Sandpaper machine", the names vary from place to place.
The standard name is "Wall Sander".
Nowadays, because fewer and fewer young people are entering the decoration industry, everyone wants to enter a factory and have a decent job.
Renovation, especially whitening or other essential walls, is inseparable from painters. Painting work is dusty and dirty, so fewer and fewer people are engaged in it. industry.
With the current economic development, especially the rapid development of real estate, the decoration industry is also developing rapidly, which requires a large number of masters engaged in wall polishing.
However, many people are unwilling to do this work, resulting in an imbalance between supply and demand and a rapid increase in wages for workers and masters, and it is not always possible to find a master.
The productivity of woodworking has been greatly improved due to a large number of mechanized construction.
Paint and coating industries also urgently need the mechanization of painting tools to solve problems.
Wall polishing can be divided into dust-free polishing and dust-free polishing.
Dust sanding means using a sandboard, sandpaper plywood, or a wall grinder to directly grind the wall without having to deal with the putty dust that flows out after grinding. Although the efficiency is improved, the price of the machine is slightly cheaper. , there is still no way to solve the dust.
Dust-free sanding is to use a wall grinder or other grinding tools to grind the wall surface, and collect the putty dust produced during the grinding process at the same time.
It not only solves the problem of slow sanding speed, but also solves the generation of dust. The smooth and delicate wall surface produced by it is unmatched by manual work.
Principle of wall grinder
The wall grinder is a sanding machine disclosed by Chongqing Jiazhuang Environmental Protection Technology Co., Ltd., including dust removal loading and dust collection devices. , the dust removal device includes a shell, a dust removal motor, a dust removal protective cover and a working plate.
The dust removal device and the dust suction device are split types, and the dust removal device and the dust suction device are connected through a dust suction connecting pipe; a dust suction pipe is provided on the dust removal shield, and the dust suction pipe Connected to one end of the vacuum connection pipe, the split mechanism can not only suck the dust into the vacuum device as much as possible to avoid dust damage to the human body, but also absorb a large amount of dust at one time to avoid accidents due to frequent replacement of dust bags. Reduce work efficiency.
So, using this machine to polish walls, wooden boards, or floors is not only environmentally friendly and hygienic, but also improves work efficiency.
The company applied for a utility model patent for a vacuum sander in 2007, patent number: 200720080441.2 (obtained the corresponding authorization in 2008) Precautions for the sander
(1) Using the machine Please plug in the power when it is wet. It is strictly forbidden to operate electrical appliances when they are wet, wet or otherwise filled with water.
(Friendly reminder: It is recommended to use sockets with safety switches)
(2) When sanding relatively hard wall putty, please use coarse-grit sandpaper (optional P120/ 180 model), the speed control switch selects 3rd or 2nd gear.
(3) When polishing relatively soft wall putty, please use fine-grit sandpaper (optional P320/400 model), and select the 4th or 5th gear of the speed switch.
(4) When polishing the exterior wall, the hard sanding disc should be replaced, special sandpaper for exterior walls should be used, and the speed should not exceed 3 gears.
(5) When grinding, it is strictly forbidden to press the grinding disc against the wall for grinding, otherwise it will cause the rotation system to malfunction or be damaged
(This situation is not covered by the warranty).
(6) Do not use the grinder to grind without the vacuum cleaner working, otherwise the motor will be damaged.
(This situation is not covered by the warranty).
(7) It is strictly prohibited to step on wires, hit the motor, and operate in flammable and explosive places.
(If you do not follow the instructions, the machine is damaged by human factors such as stepping on or hitting the machine, it will not be covered by the warranty period).
(8) Pay attention to check whether the heat dissipation of each motor is good and whether the air flow is smooth.
When disassembling, make sure the power supply is disconnected to avoid unnecessary damage.
(9) Pay attention to check whether the work tray and work cover are on the same level, otherwise the work effect will be affected.
(10) Clean the dust in the vacuum cleaner in time. Too much dust will affect the vacuuming effect.
(11) The grinder/vacuum cleaner uses 220V voltage, please check before use.
Please do not use it when the voltage is unstable or too high.
(If you do not follow the instructions and forcibly use it, causing damage to the motor, it will not be covered by the warranty).
(12) It is strictly forbidden to turn on the power when the sand mill is in a free state. You must hold the sand mill before turning on the power.
(13) When the machine is not in use, it should be stored in a dry place and out of the reach of children.
Classification of wall grinders The wall grinders currently on the market are mainly divided into three categories in terms of appearance: 1. Long-pole wall grinders, which are mainly suitable for large-scale projects where flatness requirements are not high. Sanding is very fast.
2. Hand-held, compact and flexible, mainly used in interior decoration. The polished wall surface is very smooth and is at least 2 times lighter than the extension pole.
3. Sand suction all-in-one machine. Because most companies do not understand its core technology, imitation machines are easily damaged and have a high fever rate.
(Model distribution as shown below) Wall grinder classification: Detachable long pole grinder
Portable inner corner wall grinder
Sand suction integrated without Dust wall grinder

Manual and machine grinding comparison traditional Comparison between hand-held sandpaper grinding and wall grinding machine for wall grinding. The following is a comparison based on the current labor prices in Chongqing and a reference project based on a 100-square-meter wall. Manual sanding wall machine sanding wall conclusion status results status results working hours 150 yuan 3 days (one person), about 450 yuan, cost 100 yuan, 0.5 days, about 50 yuan, cost saving 250 yuan, 50 sheets of emery cloth, about 45 yuan, cost 2 sheets, 4 yuan, cost saving 41 yuan, serious dust, easy to get occupational diseases, dust-free, environmentally friendly, It can protect workers' health and flatness. Generally, the wall has marks and is flat. The wall has no marks. The delivery pass rate is high. Summary of the use of wall grinder. The use of wall grinder greatly saves manpower and material resources, greatly improves work efficiency and reduces inherent costs. The use of a wall grinder is also an important reference standard for identifying a good decoration team. It is a special tool for painters. Its wall grinding effect makes the working surface smooth, flat and delicate, and the effect is consistent over a large area. It is also used in conjunction with the use of sandpaper of different grits. , to achieve the car surface effect.
When the product is in operation, its vacuum cleaner basically absorbs the dust, which solves the environmental pollution caused by dust flying in the air and plays a protective role in the workers' health. The on-site construction environment is very clean.
