Description

Technical Field

[0001] The utility model relates to the technical field of sandblasting machines, in particular to a sandblasting machine for building decoration and fitment. Background Art

[0002] A sandblasting machine utilizes compressed air in a pipeline to transport powdery granular materials from one place to another. During the process of converting kinetic energy into potential energy, the high-speed moving sand grains scour the surface of an object, achieving the effect of improving the surface quality of the object. Therefore, it is applied in many fields. For building decoration and fitment, it is mainly used for cleaning walls and floors.

[0003] There is a existing sandblasting machine for building decoration and fitment (its authorization announcement number is: CN220197365U). When the sandblasting head of the sandblasting machine moves upward, it drives the sandblasting pipe to move. The sandblasting pipe drives the moving rod to move along the moving groove and squeezes the spring. Through the middle movement of the moving rod, the length of the sandblasting pipe increases, avoiding the breakage of the sandblasting pipe and improving the service life of the sandblasting pipe.

[0004] However, there are some deficiencies in the actual use of this kind of sandblasting machine for decoration. Since the sandblasting pipe of the sandblasting machine is inserted into the connection groove of the moving rod, and the connection groove of the moving rod is horizontally arranged. When the sandblasting head moves upward, it will pull the sandblasting pipe to move, causing the sandblasting pipe to bend at the joint with the connection groove of the front moving rod. Over time, it is easy for the sandblasting pipe of the sandblasting machine to break at the joint with the connection groove of the front moving rod. Therefore, we propose the present utility model to solve the above problems. Content of the Utility Model

A lifting drive mechanism for the lifting plate 4 is provided on the mounting frame 2. A fixing plate 8 is fixedly installed on the top side of the base 1. A plurality of movable grooves 9 are respectively formed on one side of the fixing plate 8. A conveying roller 12 is installed in each of the plurality of movable grooves 9 through an elastic tensioning mechanism. A sandblasting tank 13 is fixedly installed on the top side of the base 1. A sandblasting mechanism for the conveying roller 12 and the lifting plate 4 is provided at the discharging end of the sandblasting tank 13.

[0023] Further, the lifting drive mechanism includes a motor 5, a threaded rod 6 and a limiting rod 7. The motor 5 is fixedly installed on the top side of the mounting frame 2. One end of the threaded rod 6 is fixedly installed on the output shaft of the motor 5. The other end of the threaded rod 6 is threadedly penetrated through the lifting plate 4 and rotatably installed on the top side of the base 1. One end of the limiting rod 7 is fixedly installed on the top side of the base 1. The other end of the limiting rod 7 movably penetrates through the outside of the lifting plate 4 and is fixedly installed on the inner wall of the top side of the mounting frame 2. Through the lifting drive mechanism, it is convenient to adjust the sandblasting height of the sandblasting head 16.

[0024] Further, the elastic tensioning mechanism includes a movable block 10 and a spring 11. The movable block 10 is movably installed in the movable groove 9. The movable block 10 is rotatably connected to the corresponding conveying roller 12. One end of the spring 11 is fixedly installed on one side of the movable block 10. The other end of the spring 11 is fixedly installed on the inner wall of one side of the movable groove 9. Under the action of multiple groups of elastic tensioning mechanisms, the sandblasting pipe 15 wound around the inner walls of the U-shaped grooves of the plurality of conveying rollers 12 arranged in a staggered manner is in a tensioned state.

[0025] Specifically, the number of the conveying rollers 12 is set to four. A U-shaped groove is formed on the conveying roller 12. Adjacent two conveying rollers 12 are arranged in a staggered manner. The sandblasting pipe 15 is wound around the inner walls of the U-shaped grooves of the plurality of conveying rollers 12 arranged in a staggered manner, and is arranged in a corrugated shape.

[0026] Specifically, the sandblasting mechanism includes a sandblaster 14, a sandblasting pipe 15 and a sandblasting head 16. The sandblaster 14 is provided at the discharging end of the sandblasting tank 13. The sandblasting head 16 is provided on the lifting plate 4. One end of the sandblasting pipe 15 is connected to the discharging end of the sandblaster 14. The other end of the sandblasting pipe 15 is wound around the inner walls of the U-shaped grooves of the four conveying rollers 12 in sequence and is communicated with the sandblasting head 16. Through the sandblasting mechanism, it is convenient to convey the sand grains in the sandblasting tank 13 to the sandblasting head 16 through the sandblasting pipe 15, and the building materials are sandblasted through the sandblasting head 16.

[0027] Furthermore, universal wheels 17 are provided at the four corner positions on the bottom side of the base 1, and a pushing mechanism is provided on the top side of the base 1. With the multiple universal wheels 17, it is convenient to move the entire sandblasting device near the building materials that need to be sandblasted.

[0028] Specifically, the pushing mechanism includes a bent rod 18 and a push rod 19.

[0029] During use: By pushing the push rod 19 on the two bent rods 18 and cooperating with the multiple universal wheels 17, the entire sandblasting device is moved near the building materials that need to be sandblasted; By starting the sandblaster 14, the sand grains in the sandblasting tank 13 are conveyed to the sandblasting head 16 through the sandblasting pipe 15, and the building materials are sandblasted through the sandblasting head 16. At the same time, by driving the motor 5, the threaded rod 6 is driven to rotate, so that the lifting plate 4 moves up or down in the lifting groove 3, and the limiting rod 7 limits the lifting plate 4 to prevent the lifting plate 4 from shifting during the lifting movement, realizing the adjustment of the sandblasting height of the sandblasting head 16; At the same time, when the sandblasting head 16 is adjusted to rise, it will pull the sandblasting pipe 15 to move towards the sandblasting head 16. Under the elastic force of the springs 11 in the multiple movable grooves 9, the sandblasting pipe 15 wound around the inner walls of the U-shaped grooves of the multiple conveying rollers 12 arranged in a staggered manner is tightened. Therefore, since the sandblasting pipe 15 is wound around the inner walls of the U-shaped grooves of the multiple conveying rollers 12 arranged in a staggered manner, it is avoided that the sandblasting pipe 15 is disconnected due to bending during the process of adjusting the height of the sandblasting head 16, ensuring the service life of the sandblasting pipe 15 of the sandblasting machine.
