Description

Technical Field

[0001] The invention relates to the technical field of wall grinding equipment, in particular to a wall grinding device for building decoration construction. Background Art

[0002] A wall grinder is a tool that replaces the traditional manual sandpaper grinding of walls or objects to achieve the purpose of flatness, dust-free, protecting the physical and mental health of workers, optimizing the working environment, improving work efficiency, and improving the quality of decoration. Wall grinding is divided into dusty grinding and dust-free grinding. Machines for grinding walls are collectively referred to as wall grinders, also known as "wall grinders", "wall sanding machines", "putty grinders", "wall grinding machines", "white grinders", "dust suction sanders", "sanding machines", and "sandpaper machines". Although the existing wall grinders are very convenient for grinding the surrounding walls, they are extremely troublesome when grinding the top walls, and a large amount of dust will appear in the process of grinding the walls. The dust floating in the air not only pollutes the environment, but also brings harm to the workers. Therefore, the prior art proposes a wall grinding device for construction with patent number CN202111303056.0. The wall is polished as a whole by determining the lowest point of the wall, so that the wall can be uniformly flat. At the same time, this device only requires one person to complete the entire work of polishing the wall, saving time and effort, greatly improving work efficiency. At the same time, through the automated and mechanized working methods, the inaccurate precision caused by manual polishing is avoided, and the flatness of the wall polishing is effectively improved.

[0003] However, when the grinding disc of this device is actually grinding the wall, since the grinding disc is in a disc shape, when the grinding disc contacts the top of the wall, it is unable to grind the wall on the left and right ends of the top of the grinding disc, resulting in certain grinding dead angles and poor grinding effect.

The transmission shafts at the front and rear ends of the dual output shaft motor in the lower connecting plate are connected to the shafts through chain belts, and the upper connecting plate rotates 90° up and down above the lower connecting plate through the shafts.

[0009] As a further solution of the present invention: a slide groove matching the top of the upper connecting plate is arranged inside the bottom end of the mounting column, the top of the upper connecting plate is embedded in the slide groove below the inside of the mounting column, and the mounting column rises and falls vertically on the top of the upper connecting plate.

[0010] As a further solution of the present invention: the grinding assembly is composed of an inner servo motor, a connecting plate, connecting teeth, a limit plate, a reciprocating column, a collecting plate and a grinding plate; Specifically, an internal servo motor is fixed on the upper interior of the mounting column, the left and right ends of the top of the mounting column are rotatably connected to connecting plates, the left and right ends of the connecting plates are rotatably connected to connecting teeth, the front and rear ends on the left and right sides of the mounting column are fixed with limiting plates, a reciprocating column is longitudinally embedded between the two limiting plates, a collecting plate is fixed to the top of the two reciprocating columns through the mounting plate, and a grinding plate is fixed to the top of the collecting plate.

There is no dead angle in the process of grinding the wall, and the grinding effect on the wall is better.

[0016] 2. Before grinding the wall, the dual-output shaft motor drives the lower connecting plate to rotate around the top of the upper connecting plate to adjust the grinding angle of the grinding plate, so that the device can grind the vertical surface and the top surface of the wall in the building. The servo motor drives the screw to rotate in the bottom plate, so that the bottom plate pushes the grinding plate on the top of the device to move left or right to adjust the grinding position of the top grinding plate of the device. The bottom hydraulic cylinder and the upper hydraulic cylinder push the lower connecting plate and the mounting column upward to push the grinding plate at the top of the device upward, adjust the grinding height of the grinding plate or make the grinding plate close to the top of the wall, which has high flexibility and is more convenient to use. During the grinding process, since a plurality of hollow step grooves are equidistantly arranged inside the grinding plate, the grinding debris and dust will fall along the hollow step grooves into the collection plate at the bottom of the grinding plate. After that, the industrial vacuum cleaner can attract and collect the debris and dust through the vacuum tube to avoid dust and debris splashing during the grinding process, thereby further optimizing the working environment.

The bottom end of the lower connecting plate 202 is embedded in the slide groove on the upper part of the bottom plate 2. The lower connecting plate 202 is lifted up and down vertically in the slide groove on the upper part of the bottom plate 2. The front and rear ends of the bottom of the upper connecting plate 204 are fixed with shafts, which are longitudinally embedded in the front and rear ends above the lower connecting plate 202. The transmission shafts of the front and rear ends of the dual output shaft motor 203 in the lower connecting plate 202 are connected to the shafts through a chain belt. The upper connecting plate 204 rotates 90 degrees up and down above the lower connecting plate 202 through the shafts. Before wall surface grinding, the dual output shaft motor 203 drives the lower connecting plate 202 to rotate around the top of the upper connecting plate 204 to adjust the grinding angle of the grinding plate 307, so that the device can grind the vertical surface and the top surface of the wall in the building; A slide groove that fits with the top of the upper connecting plate 204 is provided inside the bottom end of the mounting column 3, and the top of the upper connecting plate 204 is embedded in the slide groove below the inside of the mounting column 3, and the mounting column 3 rises and falls vertically on the top of the upper connecting plate 204; The bottom hydraulic cylinder 201 and the upper hydraulic cylinder 205 respectively push the lower connecting plate 202 and the mounting column 3 upward to push the grinding plate 307 at the top of the device upward, thereby adjusting the grinding height of the grinding plate 307 or making the grinding plate 307 close to the wall top, which is highly flexible and more convenient to use.

[0021] Example 2, please refer to Figure 1-7 , Embodiment 2 differs from Embodiment 1 in that the grinding assembly is composed of an inner servo motor 301, a connecting plate 302, a connecting tooth 303, a limiting plate 304, a reciprocating column 305, a collecting plate 306 and a grinding plate 307; An internal servo motor 301 is fixed on the upper part of the interior of the mounting column 3, and the left and right ends of the top of the mounting column 3 are both rotatably connected to the connecting disk 302, and the left and right ends of the connecting disk 302 are both rotatably connected to the connecting teeth 303, and the front and rear ends of the left and right sides of the mounting column 3 are fixed with limit plates 304, and a reciprocating column 305 is longitudinally embedded between the two limit plates 304, and the tops of the two reciprocating columns 305 are fixed with collecting plates 306 through the mounting plates, and the tops of the collecting plates 306 are fixed with grinding plates 307; The inner servo motor 301 is rotatably connected to the connecting disks 302 at the left and right ends of the mounting column 3 through a chain belt. A gear disk is provided on the top of the connecting disk 302. The teeth on the outer wall of the gear disk on the connecting disk 302 mesh with the teeth below the connecting teeth 303 at the left and right ends thereof. The reciprocating column 305 is arranged between the two connecting teeth 303. 3-8 latching teeth are evenly arranged on the upper left side of the connecting teeth 303. The latching teeth on the upper left side of the connecting teeth 303 fit into the latching groove in the middle of the reciprocating column 305. When the grinding plate 307 is close to the wall and grinding the wall, the internal servo motor 301 drives the connecting plate 302 to rotate at the same time. The connecting plate 302 rotates and drives the two connecting teeth 303 on the left and right ends thereof to rotate clockwise at the same time. At this time, the left side of the connecting tooth 303 on the right side is embedded in the reciprocating column 305. Therefore, the connecting tooth 303 on the right side will push the reciprocating column 305 to move backward along the limiting plate 304 during the clockwise rotation of the connecting tooth 303. When the connecting tooth 303 on the right rotates clockwise and disengages from the reciprocating column 305, the tooth on the right side of the connecting tooth on the left side will be embedded in the left side of the reciprocating column, and the left connecting tooth 303 rotating clockwise will push the reciprocating column 305 to move forward along the limiting plate 304 until the tooth on its outer wall is disengaged from the outer side of the reciprocating column 305. When disengaged, the connecting tooth 305 on the right side will be embedded in the reciprocating column 305 again to push the reciprocating column 305 backward, and the cycle will continue, so that the reciprocating column 305 drives the collecting plate 306 and the grinding plate 307 connected above it to reciprocate back and forth in front of the wall to grind the wall surface. There is no dead angle in the process of grinding the wall surface, and the grinding effect on the wall surface is better. The two limit plates 304 are symmetrically arranged around the transverse central axis of the mounting column 3. The insides of the two limit plates 304 are provided with limit holes of the same size as the vertical cut area of ​​the front and rear ends of the reciprocating column 305. The reciprocating column 305 slides back and forth in the horizontal direction between the two limit plates 304. The main function of the limiting plate 304 is to limit and guide the reciprocating column 305 to avoid misalignment and deviation during the forward and backward movement of the reciprocating column 305.

[0022] Example 3, please refer to Figure 1-7 , Embodiment 3 is different from Embodiment 2 in that the grinding plate 307 is arranged in a rectangular shape, and 64 hollow step grooves with larger upper part and smaller lower part are arranged equidistantly inside the grinding plate 307, and the lower part of the step groove is connected to the inside of the collecting plate 306, and the bottom of the collecting plate 306 is arranged in an inclined shape with the left side higher and the right side lower, and the dust suction pipes of the two industrial vacuum cleaners 101 are connected to the right side of the inside of the collecting plate 306; During the grinding process, since the grinding plate 307 has multiple hollow step grooves equidistantly arranged inside, the grinding debris and dust will fall along the hollow step grooves into the collecting plate 307 at the bottom of the grinding plate 306. Afterwards, the two industrial vacuum cleaners 101 can attract and collect the grinding debris and dust through the vacuum tube, thereby avoiding the splashing of dust and debris during the grinding process, and further optimizing the working environment.

[0023] The above are only preferred embodiments of the present invention. It should be pointed out that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present invention.
