Abstract
Description
Technical Field
[0001] This application relates to the field of sandblasting, and more specifically, to a sandblasting device with nozzle anti-clogging function. Background Technology
[0002] Interior decoration, also known as renovation or refurbishment, refers to the work carried out within a specific area and scope, including plumbing and electrical work, walls, floors, ceilings, landscaping, etc., based on certain design concepts and aesthetic rules, forming a complete set of construction and design plans. Decoration is the artistic processing of household items or living environments. Methods include complete package, full package, partial package (light labor and auxiliary materials), and labor-only package. When decorating wall panels, sandblasting treatment is required.
[0003] After the decorative wall is cut and processed, the surface of the wall needs to be sandblasted to ensure its use. However, when using existing sandblasting equipment, the sandblasting liquid needs to be sprayed out from the nozzle, and the diameter of the nozzle is fixed. Some abrasive material is easy to clog inside the nozzle, affecting the normal use of the sandblasting equipment. In addition, the nozzle is usually welded or installed with bolts, which is inconvenient when the nozzle needs to be replaced due to wear of abrasive material, reducing the service life of the equipment.
[0004] Chinese patent application CN202220414237.4 discloses a sandblasting device for decoration and renovation with a nozzle anti-clogging structure, including a sandblasting tank and a nozzle. The sandblasting tank has casters fixedly connected to its four bottom corners, a handle fixedly connected to its left side, an observation window on its front, and a feeding port on its top. This simple structure enables quick nozzle replacement, avoids pipe blockage, improves the service life of the sandblasting device, and is easy to operate and highly practical.
[0005] The above solution also has the following shortcomings: When in use, the blades mainly rotate at high speed around the shaft, which makes it difficult to cover the edge area of the connecting pipe. This causes sand to easily accumulate on the inner wall of the pipe, which is not easy to clean in time, thus affecting the anti-clogging and sandblasting effect and reducing the practicality of the device. Utility Model Content
[0006] To overcome the above shortcomings, this application provides a sandblasting device with nozzle anti-clogging function, which aims to improve the problem that during use, the blades mainly concentrate on high-speed rotation around the shaft, making it difficult to cover the edge area of the connecting pipe. This results in sand material easily adhering and accumulating on the inner wall of the pipe, which is not easy to clean in time, thus affecting the anti-clogging and sandblasting effect and reducing the practicality of the device.
[0007] This application provides a sandblasting device with nozzle anti-clogging function, including a sandblasting structure and a cleaning structure. The sandblasting structure includes a sandblasting machine, a metal hose, a connecting pipe, and a nozzle. The two ends of the metal hose are respectively connected to the discharge port of the sandblasting machine and the connecting pipe. The nozzle is connected to the connecting pipe. The cleaning structure includes a drive assembly and two U-shaped scrapers. The drive assembly is disposed inside the connecting pipe. The two U-shaped scrapers are connected to the drive assembly and are in contact with the inner wall of the connecting pipe. The feed port of the sandblasting machine is connected to an external sandblasting tank.
[0008] In one specific implementation, the drive assembly includes a motor, a first rotating shaft, a fixed housing, a support rod, a first bevel gear, two second rotating shafts, and two second bevel gears. The motor is mounted on one side of the connecting pipe. The first rotating shaft is fixedly connected to the output end of the motor and rotatably connected to the connecting pipe. The support rods are fixedly connected to both sides of the fixed housing and are fixedly connected to the inner wall of the connecting pipe. The first rotating shaft and the two second rotating shafts are rotatably connected to the fixed housing. The first bevel gear is fixedly connected to the outer ring of the first rotating shaft. The outer rings of the two second rotating shafts are fixedly connected to the second bevel gears, and the two second bevel gears mesh with the first bevel gears. The two U-shaped scrapers are fixedly connected to the outer rings of the two second rotating shafts.
[0009] In the above implementation process, the arrangement of the motor, the first rotating shaft, the fixed shell, the support rod, the first bevel gear, the two second rotating shafts and the second bevel gear can easily drive the two U-shaped scrapers to clean the sand material on the inner wall of the connecting pipe, avoid clogging, and improve the sandblasting effect.
[0010] In one specific implementation, both outer rings of the second rotating shafts are fixedly connected with helical blades.
[0011] In the above implementation process, spiral blades are fixedly connected to the outer ring of the second rotating shaft, which can easily push the sand towards the nozzle and reduce the risk of clogging. At the same time, the spiral directions of the two spiral blades are opposite, which makes it easy for the sand to move in the same direction.
[0012] In one specific implementation, an installation assembly is provided on one side of the connecting pipe. The installation assembly includes a positioning groove, an installation ring, a fixing ring, and a fixing sleeve. The installation ring is fixedly connected to one side of the nozzle. The positioning groove is opened on one side of the connecting pipe. The installation ring is disposed in the positioning groove. The fixing ring is fixedly connected to one side of the connecting pipe. The outer ring of the installation ring fits against the fixing ring. The fixing sleeve is threadedly connected to the fixing ring. The fixing sleeve fits against one side of both the fixing ring and the installation ring.
[0013] In the above implementation process, the positioning groove, mounting ring, fixing ring and fixing sleeve can facilitate quick and easy disassembly and assembly of the nozzle.
[0014] In one specific implementation, a sealing gasket is fixedly connected to one side of the mounting ring.
[0015] In the above implementation process, the sealing effect can be easily improved by fixing a sealing gasket to one side of the mounting ring.
[0016] In one specific implementation, the outer ring of the fixing sleeve is provided with a plurality of grooves evenly distributed.
[0017] In the above implementation process, by evenly opening several grooves on the outer ring of the fixed sleeve, the friction force during manual screwing can be easily increased, especially in humid or oily environments, making operation easier and reducing reliance on tools.
[0018] In one specific implementation, the inner wall of the connecting pipe is provided with a slope.
[0019] In the above process, by setting an inclined surface on the inner wall of the connecting pipe, the sand can be easily guided to flow in a concentrated manner towards the nozzle, reducing sand retention at the corners of the pipe wall and reducing the risk of local wear and blockage.
[0020] Compared with the prior art, the beneficial effects of this application are as follows: the drive component drives the two U-shaped scrapers to rotate, which facilitates the cleaning of the sand on the inner wall of the connecting pipe, avoids clogging, and improves the sandblasting effect. The rotation of the drive component also drives the spiral blades to rotate, which facilitates the movement of the sand towards the nozzle and reduces the risk of clogging. The nozzle can be easily and quickly disassembled and assembled through the installation component. Attached Figure Description

Detailed Implementation
[0027] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.
[0028] Please see Figure 1 This application provides a sandblasting device with nozzle anti-clogging function, including a sandblasting structure 10 and a cleaning structure 20.
[0029] Please see Figure 1 , Figure 2 and Figure 4 The sandblasting structure 10 includes a sandblasting machine 110, a metal hose 120, a connecting pipe 130, and a nozzle 140. The two ends of the metal hose 120 are connected to the discharge port of the sandblasting machine 110 and the connecting pipe 130, respectively, and the nozzle 140 is connected to the connecting pipe 130.
[0030] In a specific configuration, an installation component 150 is provided on one side of the connecting pipe 130. The installation component 150 includes a positioning groove 151, an installation ring 152, a fixing ring 153, and a fixing sleeve 154. The installation ring 152 is fixedly connected to one side of the nozzle 140. The positioning groove 151 is opened on one side of the connecting pipe 130, and the installation ring 152 is set in the positioning groove 151. The fixing ring 153 is fixedly connected to one side of the connecting pipe 130. The outer ring of the installation ring 152 fits against the fixing ring 153. The fixing sleeve 154 is threadedly connected to the fixing ring 153. The fixing sleeve 154 fits against one side of the fixing ring 153 and the installation ring 152 respectively. The positioning groove 151, the installation ring 152, the fixing ring 153, and the fixing sleeve 154 enable convenient and quick assembly and disassembly of the nozzle 140.
[0031] In the specific setup, a sealing gasket 160 is fixedly connected to one side of the mounting ring 152. By fixing the sealing gasket 160 to one side of the mounting ring 152, the sealing effect can be easily improved.
[0032] In the specific setting, the outer ring of the fixing sleeve 154 is evenly provided with several grooves. By evenly providing several grooves on the outer ring of the fixing sleeve 154, the friction during manual turning can be increased. Especially in humid or oily environments, the operation is more labor-saving and the reliance on tools is reduced.
[0033] In the specific setup, the inner wall of the connecting pipe 130 is provided with a slope. By providing a slope on the inner wall of the connecting pipe 130, the sand can be easily guided to flow in a concentrated manner towards the nozzle 140, reducing sand retention at the corners of the pipe wall and reducing the risk of local wear and blockage.
[0034] Please see Figure 1 , Figure 2 and Figure 3 The cleaning structure 20 includes a drive assembly 210 and two U-shaped scrapers 220. The drive assembly 210 is located inside the connecting pipe 130. The two U-shaped scrapers 220 are connected to the drive assembly 210 and fit against the inner wall of the connecting pipe 130. The feed port of the sandblasting machine 110 is connected to the external sandblasting tank.
[0035] In a specific configuration, the drive assembly 210 includes a motor 211, a first rotating shaft 212, a fixed housing 213, support rods 214, a first bevel gear 215, two second rotating shafts 216, and a second bevel gear 217. The motor 211 is mounted on one side of the connecting pipe 130. The first rotating shaft 212 is fixedly connected to the output end of the motor 211 and rotatably connected to the connecting pipe 130. Support rods 214 are fixedly connected to both sides of the fixed housing 213 and are fixedly connected to the inner wall of the connecting pipe 130. The first rotating shaft 212 and the two second rotating shafts 216 are rotatably connected to the fixed housing 213. Wheel 215 is fixedly connected to the outer ring of the first rotating shaft 212. The outer rings of the two second rotating shafts 216 are each fixedly connected to a second bevel gear 217. The two second bevel gears 217 mesh with the first bevel gear 215. The two U-shaped scrapers 220 are fixedly connected to the outer rings of the two second rotating shafts 216. The arrangement of motor 211, first rotating shaft 212, fixed shell 213, support rod 214, first bevel gear 215, two second rotating shafts 216 and second bevel gear 217 can easily drive the two U-shaped scrapers 220 to clean the sand on the inner wall of the connecting pipe 130, avoid clogging, and improve the sandblasting effect.
[0036] In the specific configuration, spiral blades 230 are fixedly connected to the outer rings of the two second rotating shafts 216. The spiral blades 230 fixedly connected to the outer rings of the two second rotating shafts 216 can easily push the sand material towards the nozzle 140, while reducing the risk of clogging. At the same time, the spiral directions of the two spiral blades 230 are opposite, which makes it easy for the sand material to move in the same direction.
[0037] The working principle of this sandblasting equipment with nozzle anti-clogging function is as follows: When using the sandblasting equipment with nozzle anti-clogging function, the sandblasting machine 110 delivers sand to the connecting pipe 130 through the metal hose 120. After being guided by the inclined inner wall, the sand flows to the nozzle 140 and is sprayed out. At the same time, the motor 211 drives the first rotating shaft 212 to rotate the first bevel gear 215. Through the meshing transmission with the two second bevel gears 217, the two second rotating shafts 216 set in opposite directions rotate synchronously. This transmission process is stably supported by the fixed shell 213 fixed inside the pipe by the support rod 214. The spiral blades 230 fixed on the outer ring of the second rotating shaft 216 work together in opposite spiral directions to continuously push the sand towards the nozzle 140. At the same time, the two U-shaped scrapers 220 rotating synchronously with the second rotating shaft 216 clean the inner wall of the connecting pipe 130, effectively removing residual sand from the pipe wall, which can easily reduce the risk of clogging and achieve simultaneous improvement in anti-clogging and sandblasting efficiency.
[0038] It should be noted that the specific model and specifications of the sandblasting machine 110 and the motor 211 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.
[0039] The power supply and operating principle of the sandblasting machine 110 and the motor 211 are clear to those skilled in the art and will not be described in detail here.
[0040] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
