Description

Technical Field

[0001] This utility model relates to the field of sandblasting equipment technology, and in particular to a sandblasting device for decoration and construction. Background Technology

[0002] Architectural decoration and renovation refers to the various treatments applied to the interior and exterior surfaces and spaces of a building using decorative materials or ornaments to protect its main structure, improve its functionality, and enhance its aesthetics. Sandblasting machines are frequently used in this process to treat the surfaces of objects, removing burrs, dirt, and other imperfections. Sandblasting machines fall under the category of air-pumped machinery. They utilize compressed air within a pipeline to transport powdery granular material from one point, causing the abrasive particles to quickly adhere to the surface of the object, thereby improving its surface quality.

[0003] A search revealed that patent CN221290880U discloses a sandblasting device for interior decoration construction. By incorporating a storage device, the spray gun hose connected to the pipeline can be quickly and neatly stored after use, reducing the inconvenience of carrying and using the long hose and improving the convenience and neatness of storage after construction. However, this device has the following drawbacks: when adding sand to the tank, it cannot remove large particles; if large particles are ejected from the spray gun, it will not only affect the sandblasting effect but also cause clogging or damage to the spray gun. Furthermore, because the spraying position during interior decoration construction is flexible, this device cannot be moved flexibly according to needs, thus requiring further improvement.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-5 As shown, a sandblasting device for decoration and construction includes a base 1. Multiple support legs 2 are fixed to the upper surface of the base 1. A sandblasting tank main unit 3 is fixed to the top of the multiple support legs 2. A connecting air pipe 4 is fixed to the sand discharge port at the bottom of the sandblasting tank main unit 3. The connecting air pipe 4 is connected to a sandblasting gun head 5. A cylinder 6 is located at the top of the interior of the sandblasting tank main unit 3, and a screen 7 is fixed to the bottom of the cylinder 6. A top flap 61 is fixed to the top of the cylinder 6. A side plate 31 is fixed to the top of the sandblasting tank main unit 3, and multiple first springs 8 are fixed to the upper surface of the side plate 31. The tops of the multiple first springs 8 are connected to the top flap... The lower surface of plate 61 is attached, and two symmetrical guide rods 12 are fixed on the upper surface of side plate 31. The top flip plate 61 has through holes 62 for the guide rods 12 to pass through. The top of the guide rod 12 is provided with an end plate 9, and a second spring 10 is fixed on the lower surface of the end plate 9. The bottom end of the second spring 10 is attached to the upper surface of the top flip plate 61. A retainer 11 is fixed on the lower surface of the end plate 9. A fixing component 13 for fixing the retainer 11 is provided on the side wall of the top of the guide rod 12. A drive component is installed inside the sandblasting tank main unit 3 and below the cylinder 6. Multiple casters 18 are fixed on the lower surface of the base 1.

[0024] In this embodiment, the connection method and working principle of the sandblasting tank main unit 3, the connecting air pipe 4 and the sandblasting gun head 5 are the same as those of the existing sandblasting machine, and the specific working principle will not be described in detail.

[0025] A push handle 17 is fixed to one side of the upper surface of the base 1.

[0026] In this embodiment, since the bottom of the base 1 is equipped with casters 18, it is easy to move the device by pushing the handle 17. In actual construction, the device can be moved according to the usage requirements, making it more flexible and convenient to use.

[0027] The sleeve 11 is fitted onto the top surface of the guide rod 12, and the side wall of the sleeve 11 has a locking hole 111. The fixing component 13 includes a groove 131 opened on the side wall of the guide rod 12. A third spring 132 is fixed on the inner side wall of the groove 131. A locking tooth 133 is fixed on the other end of the third spring 132. The end of the locking tooth 133 away from the third spring 132 is inserted into the locking hole 111.

[0028] The top of the end of the locking tooth 133 away from the third spring 132 is designed with a slope.

[0029] In this embodiment, the retaining sleeve 11 at the bottom of the end plate 9 is fixed to the top of the guide rod 12 by the fixing assembly 13. This allows the end plate 9 to be disassembled. When installing the end plate 9, the retaining sleeve 11 is directly placed on the top of the guide rod 12. The retaining sleeve 11 presses the retaining teeth 133 back into the groove 131 along the inclined surface of the retaining teeth 133. When the retaining hole 111 aligns with the retaining teeth 133, the third spring 132 presses the retaining teeth 133 into the retaining hole 111, thereby fixing the retaining sleeve 11. At this time, the second spring 10 acts as a limiter above the top flip plate 61, while the first spring 8 provides support for the top flip plate 61.

[0030] When it is necessary to clean large particles of impurities on the screen 7 at the bottom of the cylinder 6, the end plate 9 needs to be removed first. To remove the end plate 9, first squeeze the retaining teeth 133 to separate them from the retaining holes 111 on the retaining sleeve 11. Then, remove the retaining sleeve 11 from the top of the guide rod 12, thus removing the end plate 9. Next, slide the top flap 61 upwards along the guide rod 12 to remove the top flap 61, thereby removing the cylinder 6 from the inside of the sandblasting tank main unit 3.

[0031] Both the guide rod 12 and the through hole 62 are square structures, and the guide rod 12 and the through hole 62 are slidably connected.

[0032] By setting the guide rod 12, the up-and-down movement of the top flap 61 can be guided.

[0033] The drive assembly includes a motor 14 fixed to the outer wall of the sandblasting tank main unit 3. A horizontal shaft 15 is fixed to the output end of the motor 14. The horizontal shaft 15 passes through the side wall of the sandblasting tank main unit 3 and is rotatably connected to the side wall of the sandblasting tank main unit 3 through a bearing. An eccentric cam 16 is fixed at both ends of the surface of the horizontal shaft 15 and below the side wall of the cylinder 6.

[0034] After the start motor 14 drives the horizontal shaft 15 and the eccentric cam 16 to rotate, when the long end of the eccentric cam 16 rotates upward, the eccentric cam 16 will push the cylinder 6 upward. When the long end of the eccentric cam 16 rotates downward and separates from the cylinder 6, the cylinder 6 moves downward, thereby realizing the vibration of the cylinder 6, which improves the screening effect of the screen 7 on sand.

[0035] Working principle: In use, first pour sand into the cylinder 6, then start the motor 14 to drive the eccentric cam 16 to rotate. The eccentric cam 16 drives the cylinder 6 to vibrate inside the sandblasting tank main unit 3, thereby sieving the sand through the screen 7. During sieving, start the sandblasting tank main unit 3 and use the sandblasting gun head 5 to blast the workpiece. When it is necessary to clean the impurities sieved out inside the cylinder 6, first remove the end plate 9 at the top of the guide rod 12, then slide the top flap 61 upwards along the guide rod 12 to remove the cylinder 6 from inside the sandblasting tank main unit 3. After cleaning the impurities inside the cylinder 6, reverse the operation to reinstall the cylinder 6.
