Description

Technical Field

[0001] This utility model relates to the field of sandblasting technology, specifically a sandblasting device for building decoration and renovation construction. Background Technology

[0002] Building decoration and renovation construction refers to engineering activities that decorate and renovate the interior and exterior of buildings, aiming to enhance the aesthetics, comfort, and functionality of buildings. It covers all aspects from basic renovation to high-end decoration and is an important link after the completion of building construction. Sandblasting equipment for building decoration and renovation is a device used to treat the surface of building decoration materials. It is widely used for cleaning, roughening, rust removal and texture treatment of materials such as walls, floors and metal decorative parts. The working principle of sandblasting equipment is to use compressed air or high-pressure water flow as power to accelerate abrasive materials such as quartz sand, sand grains, steel grit, glass beads and so on, and then spray them at high speed onto the surface of the workpiece through the nozzle. The abrasive material generates friction and impact with the surface of the workpiece under high-speed impact, thereby achieving the effects of cleaning, polishing, roughening or increasing the adhesion of coatings.

[0003] However, when using this equipment, in order to ensure the smooth operation of the equipment, a stirring rod is usually installed inside the sandblasting device to break up the abrasive particles that are stuck together due to moisture. However, the stirring rod may not be able to break up all the stuck sand particles immediately. If the sandblasting mechanism on the equipment extracts abrasive particles that have not yet been broken up by the stirring rod, it may affect the operation of the equipment. Therefore, it does not meet the existing needs. In this regard, we propose a sandblasting device for building decoration and renovation construction. Utility Model Content

[0004] The purpose of this utility model is to provide a sandblasting device for building decoration and renovation construction, in order to solve the problems mentioned in the background art. When using this device, in order to ensure the smooth operation of the device, a stirring rod is usually installed inside the sandblasting device to break up the abrasive particles that are stuck together due to moisture. However, the stirring rod may not be able to break up all the stuck sand particles immediately. If the sandblasting mechanism on the device extracts abrasive particles that have not yet been broken up by the stirring rod, it may affect the operation of the device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sandblasting device for building decoration and renovation construction, comprising a can-shaped sandblasting machine, wherein a stepper motor is fixedly installed on the upper side inside the can-shaped sandblasting machine, the output shaft of the stepper motor is connected to a transmission shaft through a coupling, a metal ring is fixed on the outer side of the transmission shaft and connected to the can-shaped sandblasting machine through a roller bearing, a pressure roller shaft is installed at the middle position of the front and rear end faces of the metal ring, a metal pressure roller is fixedly sleeved on the outer surface of the pressure roller shaft, and a filter screen fixed inside the can-shaped sandblasting machine is provided below the lower end face of the two metal pressure rollers, and the lower end face of the metal pressure roller is in contact with the upper end face of the filter screen.

[0006] Preferably, a first lifting sleeve is fixedly sleeved on the lower side of the outer surface of the transmission shaft. A wave-shaped lifting slide rail is engraved on the outer surface of the first lifting sleeve. A slider is slidably installed on both sides inside the wave-shaped lifting slide rail. A second lifting sleeve is movably sleeved on the lower side of the outer surface of the first lifting sleeve on the outer side of the two sliders.

[0007] Preferably, an L-shaped rod is fixedly connected to the middle position of the front and rear end faces of the second lifting sleeve. A convex impact head is slidably installed on the upper end face of the top end of the L-shaped rod. The convex impact head is convex in shape, and a spring is connected to the lower end face of the convex impact head.

[0008] Preferably, the convex impact head is located below the filter screen, and a rubber protective sleeve is installed on the upper end face of the convex impact head.

[0009] Preferably, a strip-shaped sealing groove is provided at both the top and bottom of the L-shaped rod. The inside of the strip-shaped sealing groove is provided with a strip-shaped sealing plate that fits against its inner wall. The outer surface of the strip-shaped sealing plate fits against the inner wall of the strip-shaped sealing groove, and the surface of the strip-shaped sealing plate facing the L-shaped rod is fixed to the L-shaped rod.

[0010] Preferably, a stirring blade is fixedly connected to the lower end face of the transmission shaft, and a stirring trough located inside the can-shaped sandblasting machine is provided on the outer side of the stirring blade, and a sandblasting mechanism is fixedly installed at the middle position of the lower inner wall of the stirring trough.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model has a filter screen above the stirring blade. When the stepper motor is started to drive the stirring blade to rotate, two metal pressure rollers located above the filter screen will roll back and forth synchronously along the upper surface of the filter screen. The metal pressure rollers rolling along the upper surface of the filter screen can crush the abrasive that is stuck together due to moisture. The above technical solution can prevent the clumps of abrasive that have just been added to the can-shaped sandblasting machine and have not yet been broken up by the stirring blade from contacting the sandblasting mechanism and affecting the operation of the equipment, thereby ensuring the smooth operation of the equipment during long-term operation. 2. In this invention, the stepper motor drives the stirring blade and the metal pressure roller to move the two convex impact heads located below the filter screen in a cyclic up-and-down motion. When the upward-moving convex impact head hits the filter screen, the filter screen itself will vibrate. Through this vibration, the abrasive stuck inside the mesh of the filter screen will fall off. The above technical solution can prevent the mesh of the filter screen from becoming clogged due to long-term operation of the equipment. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] The can-shaped sandblasting machine 1 (model YC), stepper motor 2 (model DM542), and filter screen 8 (model TG124) mentioned in this utility model can be obtained from the market or through private customization.

[0017] Please see Figures 1 to 4This utility model provides an embodiment of a sandblasting device for building decoration and renovation, comprising a can-shaped sandblasting machine 1. A stepper motor 2 is fixedly installed on the upper side inside the can-shaped sandblasting machine 1. The output shaft of the stepper motor 2 is connected to a transmission shaft 3 via a coupling. A metal ring 5 is fixed on the outer side of the transmission shaft 3 and connected to the can-shaped sandblasting machine 1 via a roller bearing. A pressure roller shaft 6 is installed at the middle position of the front and rear end faces of the metal ring 5. A metal pressure roller 7 is fixedly sleeved on the outer surface of the pressure roller shaft 6. A fixed part is provided below the lower end face of the two metal pressure rollers 7. The filter screen 8 is located inside the machine 1, and the lower end face of the metal pressure roller 7 is in contact with the upper end face of the filter screen 8; the lower end face of the transmission shaft 3 is fixedly connected to the stirring blade 4, and the outside of the stirring blade 4 is provided with a stirring tank located inside the can-shaped sandblasting machine 1, and a sandblasting mechanism is fixedly installed in the middle position of the lower end inner wall of the stirring tank; a feeding port is provided in the middle position of the upper end face of the can-shaped sandblasting machine 1, and a feeding through hole is provided on both sides of the lower end inner wall of the feeding port; when the equipment needs to be used, the stepper motor 2 is started first, and the stepper motor 2 can drive the stirring blade 4 connected to it through the transmission shaft 3 to rotate. During the rotation of the drive shaft 3, the metal ring 5, which is also fixed to it, will rotate together. During the rotation of the metal ring 5, the two pressure roller shafts 6, which are respectively installed on the front and rear ends of the metal ring 5, will revolve around the drive shaft 3. During the revolve of the pressure roller shaft 6, the metal pressure roller 7, which is sleeved on the outer surface of the pressure roller shaft 6 and whose lower end face is in contact with the upper end face of the filter screen 8, will roll back and forth along the upper end face of the filter screen 8. When the filter screen 8 starts to roll, abrasive is added into the mixing tank through the feed port. The abrasive passing through the feed port will first fall onto the upper surface of the filter screen 8. The metal pressure roller 7 rolling back and forth along the upper surface of the filter screen 8 can crush the abrasive clumps that are stuck together due to moisture in the abrasive mixture. The crushed abrasive and the abrasive that were not stuck together due to moisture will fall into the mixing tank through the mesh on the filter screen 8. Then, the stirring blade 4 rotating inside the mixing tank can prevent the abrasive from sticking together again. The above technical solution can prevent the abrasive particles that have just been added to the can-shaped sandblasting machine 1 and have not yet been broken up by the stirring blades 4 from coming into contact with the sandblasting mechanism and affecting the operation of the equipment, thereby ensuring the smooth operation of the equipment during long-term operation. Once abrasive material enters the mixing tank, the sandblasting mechanism can be activated to perform sandblasting operations.

[0018] A first lifting sleeve 9 is fixedly sleeved on the lower side of the outer surface of the transmission shaft 3. A wave-shaped lifting slide rail 10 is engraved on the outer surface of the first lifting sleeve 9. A slider 11 is slidably installed on both sides inside the wave-shaped lifting slide rail 10. A second lifting sleeve 12 is movably sleeved on the lower side of the outer surface of the first lifting sleeve 9 on the outer side of the two sliders 11. An L-shaped rod 13 is fixedly connected to the middle position of the front and rear end faces of the second lifting sleeve 12. A convex impact head 14 is slidably installed on the upper end face of the top end of the L-shaped rod 13. The convex impact head 14 is convex in shape, and a spring 15 is connected to the lower end face of the convex impact head 14. The convex impact head 14 is located below the filter screen 8, and a rubber protective sleeve is installed on the upper end face of the convex impact head 14. During the rotation of the transmission shaft 3, the first lifting sleeve 9 fixedly sleeved on the outer surface of the transmission shaft 3 will rotate together with it. During the rotation of the first lifting sleeve 9, the wave-shaped lifting slide rail 10 engraved on the outer surface of the first lifting sleeve 9 will continuously rise and fall. Since the two sliders 11, which are slidably installed on both sides inside the wave-shaped lifting slide rail 10, are indirectly and rigidly connected to the L-shaped rod 13 through the second lifting sleeve 12, the sliders 11 themselves cannot revolve. When the wave-shaped lifting slide rail 10 moves up and down continuously due to rotation, the sliders 11, which cannot revolve themselves, will move up and down in a cycle along the wave-shaped lifting slide rail 10. During the process of the sliders 11 moving up and down in a cycle, the convex impact head 14, which is indirectly connected to them, will also move up and down in a cycle. The upward-moving convex impact head 14 will eventually hit the filter screen 8, causing it to vibrate. When the filter screen 8 vibrates, the abrasive stuck inside the mesh hole of the filter screen 8 will fall off. The above technical solution can prevent the mesh hole of the filter screen 8 from being blocked due to long-term operation of the equipment. By means of the spring 15 connected to the lower end face of the convex impact head 14, when the convex impact head 14 has already struck the filter screen 8 but the convex impact head 14 is still being pushed upward, the convex impact head 14 will stay in its original position. This spring 15 can prevent the convex impact head 14 from getting stuck.

[0019] A strip-shaped sealing groove 17 is provided at both the upper and lower ends of the L-shaped rod 13. A strip-shaped sealing plate 16 is provided inside the strip-shaped sealing groove 17 and fits against its inner wall. The outer surface of the strip-shaped sealing plate 16 fits against the inner wall of the strip-shaped sealing groove 17, and the surface of the strip-shaped sealing plate 16 facing the L-shaped rod 13 is fixed to the L-shaped rod 13. By fixing the strip-shaped sealing plate 16 to the upper and lower end faces of the L-shaped rod 13 and located inside the strip-shaped sealing groove 17, it is possible to prevent the abrasive inside the can-shaped sandblasting machine 1 from entering the outer shell of the can-shaped sandblasting machine 1 through the connection between the L-shaped rod 13 and the can-shaped sandblasting machine 1.

[0020] A protective cover plate is provided above the stepper motor 2, located in the middle of the inner wall at the lower end of the feeding port, and the protective cover plate is fixed to the can-shaped sandblasting machine 1 by screws; the protective cover plate can seal and protect the stepper motor 2.
