Description

A kind of paint wall smoothing device for building construction

technical field

The invention belongs to the technical field of building construction, and particularly relates to a coating wall leveling device for building construction.

Background technique

At present, in the interior decoration and decoration projects, the decoration wall needs to be polished twice, and the polishing machine is mostly used for polishing. Due to the large amount of dust in the grinding process, the vacuum cleaner needs to be used synchronously during grinding, that is, vacuuming while grinding, the overall operation is troublesome and the efficiency is low. The waste of energy consumption is large when the dust generated by grinding is removed, which cannot meet the existing demand. At the same time, the smoother is prone to excessive grinding of individual parts, resulting in pits and affecting the aesthetics of the wall.

SUMMARY OF THE INVENTION

The purpose of the present invention is to provide a paint wall leveling device for building construction, which is simple in structure and convenient to use, and which can avoid dust from scattering when grinding the wall surface.

To this end, the technical scheme of the present invention is as follows: a paint wall leveling device for building construction, comprising a hollow casing, a motor is arranged in the casing, a grinding wheel installed on the motor shaft is arranged at the front end of the casing, and the casing is The rear end of the body is provided with a handle; it is characterized in that a cavity ring is sleeved on the outer side of the casing, and a plurality of air holes communicated with the interior of the cavity ring are provided on the side facing the grinding wheel, and the interior of the cavity ring is connected with the dust suction mechanism The upper and lower ends of the cavity ring are provided with mounting plates, the threaded rods are movably installed on the mounting plates, and a baffle plate is installed at one end of the threaded rods close to the grinding wheel.

Preferably, the cavity ring is an annular structure with a hollow interior, and the bottom of the cavity ring is provided with a dust extraction joint, one end of the dust extraction joint extends into the interior of the cavity ring, and the other end is connected to the dust suction mechanism.

Preferably, the dust suction mechanism includes a dust storage box and an exhaust fan, a dust inlet joint is provided on one side of the dust storage box, the dust inlet joint is connected with the dust outlet joint of the cavity ring through an air pipe, and the other side is provided with an air outlet The air outlet connector is connected to the exhaust fan; the dust storage box is provided with an air filter screen, and the air filter screen is located between the dust inlet connector and the air outlet connector.

When grinding the wall, the motor drives the grinding wheel to rotate, and the grinding wheel grinds the wall. At this time, the exhaust fan works, so that negative pressure is generated in the dust storage box. The air holes of the ring are sucked into the cavity ring, and then sucked into the dust storage box through the dust outlet. The occurrence of dust floating around is conducive to improving the quality of the working environment.

The upper and lower ends of the cavity ring of the present invention are provided with threaded rods through threads. When grinding a wall with a higher protrusion, the position of the threaded rod can be adjusted according to the degree of protrusion, so that the baffle and the grinding surface of the grinding wheel form a certain position Poor, when grinding the wall, when the protrusions are smoothed, the baffle is in contact with the wall, so that the grinding wheel cannot continue to grind the wall, which is beneficial to avoid the occurrence of pits caused by excessive grinding.

The invention uses the cavity ring with air holes to absorb the dust around the grinding wheel, avoids the dust floating around, and improves the quality of the working environment; movable baffles are arranged at the upper and lower ends of the cavity ring, and the baffles are used to limit the grinding depth, Protect the wall from dents.

Detailed ways

See attached image. The wall surface smoothing device described in this embodiment includes a hollow shell 1, the inner wall of the shell is attached with sound-absorbing felt, a motor 16 is installed in the shell 1, and a grinding wheel is installed on the output end of the motor 16 4. The grinding wheel 4 is located at the front end of the casing 1, the rear end of the casing 1 is provided with a handle 2, and the outer wall of the handle is covered and installed with a rubber anti-skid pad; It is a hollow ring-shaped structure, and the side facing the grinding wheel 4 is provided with a plurality of air holes 15 that communicate with the interior of the cavity ring. The bottom of the other side of the cavity ring 3 is installed with a dust outlet 8. One end of the dust outlet 8 It extends into the cavity of the cavity ring 3, and the other end is connected to the dust suction mechanism; the top and bottom of the outer side of the cavity ring 3 are provided with a mounting plate 5, and the threaded rod 6 is installed on the mounting plate 5 through threaded activities. A baffle plate 7 is installed toward the end of the grinding wheel.

The dust suction mechanism includes a dust storage box 9, a horizontal plate 11, an exhaust fan 12 and an air filter 14. The dust storage box 9 and the exhaust fan 12 are sequentially installed on the horizontal plate 11. The top plate of the dust storage box 9 And a dust inlet joint 10 and an air outlet joint 13 are respectively installed through one side plate, the dust inlet joint 10 is connected with the dust outlet joint 8 on the cavity ring 5, and the air outlet joint 13 is connected with the input end of the exhaust fan 12. , an air filter 14 is installed inside the dust storage box 9, and the air filter 14 is located between the dust inlet joint 10 and the air outlet joint 13. The upper and lower sides of the dust storage box 9 are fixed with concave clips. The air filter screen 14 is clipped on the concave clip.

When in use, connect the dust inlet joint 10 of the dust suction mechanism to the dust outlet joint 8 on the cavity ring 5 through a hose, turn on the motor 16, the motor 16 drives the grinding wheel 4 to rotate, and hold the handle 2 so that the grinding wheel 4 faces the wall. Surface grinding, at this time, the exhaust fan 12 of the dust suction mechanism is turned on. When the exhaust fan 12 is working, a negative pressure is generated in the dust storage box 9. It is sucked into the cavity ring 3 , and then flows out from the dust outlet 8 and is sucked into the dust storage box 9 . Under the action of the air filter 14 in the dust storage box 9 , the dust is blocked and collected in the dust storage box 9 .
