Description

Technical Field

[0001] This utility model relates to the field of workpiece surface treatment technology, specifically a liquid sandblasting machine. Background Technology

[0002] In various industries such as manufacturing, machining, and automotive parts, surface treatment of workpieces is a crucial step in ensuring product quality and lifespan. Sandblasting, as a highly efficient surface treatment process, uses a high-speed jet of media to impact the workpiece surface, achieving effects such as rust removal, deburring, impurity cleaning, and enhanced surface adhesion, laying a solid foundation for subsequent painting, welding, and assembly processes. With the increasing demands for surface precision and processing efficiency in industrial production, liquid sandblasting machines, due to their advantages such as uniform sandblasting, minimal damage to workpieces, and low dust pollution, are gradually gaining widespread application in the surface treatment of various precision and complex-shaped workpieces. In the existing technology, liquid sandblasting machines are usually composed of core components such as sandblasting host, media supply system, and spray gun. The working process generally involves first mixing liquid and abrasive particles in a certain proportion to form sandblasting media, then pressurizing it through a pump and spraying it onto the surface of the workpiece through the spray gun. The impact force of the media is used to complete the surface treatment. Some equipment will be equipped with independent material bins and liquid tanks to store abrasive and liquid respectively, which are transported to the mixing area through pipelines for mixing, and then transported to the spray gun for operation. Existing liquid sandblasting machines still have some areas for improvement in practical applications. The precise ratio of liquid to abrasive particles is difficult to control, often resulting in an imbalance that leads to unstable sandblasting effects and affects the consistency of workpiece surface treatment. Manual weighing and mixing are required, or pre-made liquid abrasives are used, making it impossible to adjust the particle-to-liquid ratio. Therefore, we propose a liquid sandblasting machine.

[0015] Please see Figure 1-6 This embodiment provides a technical solution: a liquid sandblasting machine, including a sandblasting machine housing 1. A material door is hinged to the right side wall of the sandblasting machine housing 1. A closing lock is provided between the material door and the right side wall of the sandblasting machine housing 1. The closing lock is a commonly used push-type spring latch lock in the prior art.

The input end of the mortar pump 26 is electrically connected to the output end of the control button 9. The sandblasting medium is transmitted forward through the conveying pipe 25, and the conveying pipe 26... The mortar pump 26 connected in series in the middle of the 5 section provides power for the medium transportation. The front end of the transportation pipe 25 passes through the rear side wall of the sandblasting machine housing 1 and is connected to the spray gun 3 through the stainless steel hose 4. The stainless steel hose 4 can be flexibly bent, making it easy for the operator to adjust the angle of the spray gun 3. The operator puts on gloves inside the gloves through the symmetrically distributed glove ports 7 on the front side wall of the sandblasting machine housing 1 and reaches into the equipment. The operator holds the spray gun 3 located inside the sandblasting machine housing 1 and presses the control button 9 at the front end of the handle of the spray gun 3.

After the mortar pump 26 pressurizes, it transports the sandblasting medium in the transportation pipe 25 to the spray gun 3 through the stainless steel hose 4. The operator operates the spray gun 3 to spray the workpiece surface on the stainless steel mesh 5 to achieve surface treatment such as rust removal, deburring, and grinding. The liquid supply assembly 21 also includes a water pipe 212 and a first valve 218. The water pipe 212 is fixedly connected to the lower end of the rubber tube 213. The lower end of the water pipe 212 is connected to the feed port of the electric screw conveyor 23. The first valve 218 is connected in series in the middle of the water pipe 212. The input end of the first valve 218 is electrically connected to the output end of the microcontroller 8, and the first valve 218 can be opened to allow water to flow. The liquid supply assembly 21 also includes a T-shaped slide rail 219, a bidirectional lead screw 215, a first infrared rangefinder 216, and a motor 217. The T-shaped slide rail 219 is fixedly connected to the left inner wall of the installation chamber 10. The extrusion blocks 214 are all slidably connected to the middle of the T-shaped slide rail 219. The bidirectional lead screw 215 is rotatably connected between the front and rear inner walls of the installation chamber 10. The front and rear ends of the bidirectional lead screw 215 are respectively threaded to the adjacent extrusion blocks 214 on the right side. Corrugated sections are provided between the two extrusion blocks 214 and the front and rear inner walls of the installation chamber 10, as well as between the two extrusion blocks 214. The bellows and the bidirectional lead screw 215 are located inside the bellows. The bellows provides external protection for the bidirectional lead screw 215 and ensures its sealing and lubrication. The first infrared rangefinder 216 is installed on the rear side of the front extrusion block 214 and works in conjunction with the rear extrusion block 214. The first infrared rangefinder 216 is bidirectionally electrically connected to the microcontroller 8. The motor 217 is installed on the rear side of the mounting chamber 10. The output shaft of the motor 217 is fixedly connected to the center of the rear end face of the bidirectional lead screw 215. The input end of the motor 217 is electrically connected to the microcontroller 8. At the output end of the machine 8, water stored in the water tank 211 flows into the rubber tube 213 through its bottom drain. Water can be replenished at any time via the water replenishment pipe on the upper side of the water tank 211. At this time, the microcontroller 8 can send a start command to the motor 217. The output shaft of the motor 217 drives the bidirectional lead screw 215 to rotate. Since the extrusion blocks 214 are slidably connected to the middle of the T-shaped slide rail 219 and are adapted to the front and rear ends of the bidirectional lead screw 215, the rotation of the bidirectional lead screw 215 will drive the two extrusion blocks 214 to slide relative to or in opposite directions, thus extruding the rubber tube 213. 3. The passable gap: The first infrared rangefinder 216 detects the distance between the two front and rear extrusion blocks 214 in real time and feeds the data back to the single-chip microcomputer 8 in both directions to determine the distance between the two extrusion blocks 214, thereby indirectly knowing the passable gap of the rubber tube 213. According to the mass formula, the density of water remains unchanged within a certain time. The passable gap of the rubber tube 213 is proportional to the water flow rate, thereby realizing the quantitative delivery of water. The water passing through the rubber tube 213 flows into the lower water pipe 212, and then flows into the left feed port of the electric screw conveyor 23. The abrasive particle supply assembly 22 includes a particle hopper 221, a particle conveying pipe 222, and a second valve 223. The particle hopper 221 is fixedly connected to the upper left end of the installation chamber 10. The upper side wall of the particle hopper 221 is provided with a particle replenishment pipe, and the lower side wall of the particle hopper 221 is provided with a particle conveying pipe 222. The lower end of the particle conveying pipe 222 is located at the upper end of the feed hopper at the left end of the electric screw conveyor 23. The second valve 223 is connected in series in the middle of the particle conveying pipe 222. The input end of the second valve 223 is electrically connected to the output end of the microcontroller 8. Quartz sand abrasive particles can be passed through by opening the second valve 223. The abrasive feeding assembly 22 also includes guide rods 224, sliders 225, baffles 226, a second infrared sensor 227, and an electric cylinder 228. The guide rods 224 are symmetrically distributed vertically and fixedly connected to the front side wall of the mounting chamber 10. A slider 225 is slidably connected between the two guide rods 224. The two guide rods 224 provide stable sliding support and guidance for the slider 225, preventing it from wobbling. A baffle 226 is fixedly connected to the left side of the slider 225. The upper side of the baffle 226 contacts the lower end face of the abrasive conveying pipe 222. A... The electric cylinder 228 has its telescopic end penetrating the rear wall of the mounting chamber 10 and fixedly connected to the rear side of the slider 225. The weight of the slider 225 is supported by two guide rods 224. The telescopic end of the electric cylinder 228 is not affected by the weight of the slider 225 and is not easily damaged. The input end of the electric cylinder 228 is electrically connected to the output end of the microcontroller 8. The second infrared sensor 227 is installed on the front side of the slider 225 and works in conjunction with the front side of the mounting chamber 10. The second infrared sensor 227 is bidirectionally electrically connected to the microcontroller 8. The quartz sand abrasive particles stored in the particle hopper 221 are guided by the particle guide rods on its lower side wall. The particle conveying pipe 222 flows downwards, and the particle replenishment pipe on the upper side of the particle hopper 221 can replenish the quartz sand abrasive at any time. At the same time, the electric cylinder 228 can be started by controlling the microcontroller 8. The telescopic end of the electric cylinder 228 pushes the slider 225 to slide along the guide rods 224 that are symmetrically distributed vertically, which drives the baffle 226 fixed to the left side of the slider 225 to move, exposing the lower end outlet of the particle conveying pipe 222. The second infrared sensor 227 installed on the front side of the slider 225 detects the distance between the slider 225 and the front side wall of the mounting bin 10 in real time and feeds the data bidirectionally back to the microcontroller 8. The microcontroller 8 adjusts the settings according to the distance data. The extension and retraction of the electric cylinder 228 controls the opening and closing of the baffle 226. According to the mass formula, the density of the quartz sand abrasive particles remains constant within a certain time. The size of the opening at the lower end of the particle conveying pipe 222 is proportional to the discharged quartz sand abrasive particles, thus achieving a quantitative supply of abrasive particles. Finally, the abrasive particles fall into the left-end feed hopper of the electric screw conveyor 23. The microcontroller 8 directs the electric screw conveyor 23, and the screw inside the electric screw conveyor 23 rotates, conveying water and quartz sand abrasive particles. During the conveying process, the water and quartz sand abrasive particles are mixed evenly to form a liquid sandblasting medium, which then flows into the storage bin 24 through the output port.

[0016] The working principle of the liquid sandblasting machine provided by this utility model is as follows: First, the worker opens the material door and places the workpiece to be surface sandblasted on the stainless steel mesh 5. Then, the door is closed. Next, the microcontroller 8 controls the opening of the first valve 218 and the second valve 223. The water stored in the water tank 211 flows into the rubber tube 213 through its bottom drain. The water replenishment pipe on the upper side of the water tank 211 can replenish water at any time. At this time, the microcontroller 8 can send a start command to the motor 217. The output shaft of the motor 217 drives the bidirectional lead screw 215 to rotate. Since the extrusion blocks 214 are slidably connected to the middle of the T-shaped slide rail 219 and are adapted to the front and rear ends of the bidirectional lead screw 215, the rotation of the bidirectional lead screw 215 will drive the two extrusion blocks 214 to slide relative to or in opposite directions. By squeezing the rubber tube 213 to allow passage through the gap, the first infrared rangefinder 216 detects the distance between the two squeezing blocks 214 in real time and feeds the data bidirectionally back to the microcontroller 8 to determine the distance between the two squeezing blocks 214, thereby indirectly knowing the passage gap of the rubber tube 213. According to the mass formula, the density of water remains constant within a certain time, and the passage gap of the rubber tube 213 is proportional to the water flow rate, thus achieving quantitative water delivery. The water passing through the rubber tube 213 flows into the lower water pipe 212, and then into the left feed inlet of the electric screw conveyor 23. At this time, the quartz sand particles stored in the particle hopper 221 flow downward through the particle conveying pipe 222 on its lower side wall. The particle replenishment pipe on the upper side of the bin 221 can replenish quartz sand abrasive at any time. Simultaneously, the electric cylinder 228 can be activated via the microcontroller 8. The telescopic end of the electric cylinder 228 pushes the slider 225 to slide along the symmetrically distributed guide rods 224, causing the baffle 226 fixed to the left side of the slider 225 to move, exposing the lower outlet of the particle conveying pipe 222. The second infrared sensor 227, installed on the front side of the slider 225, detects the distance between the slider 225 and the front wall of the mounting bin 10 in real time, and feeds the data bidirectionally back to the microcontroller 8. The microcontroller 8 adjusts the telescopic amount of the electric cylinder 228 based on the distance data, controlling the opening and closing degree of the baffle 226. According to the mass formula, the density of the quartz sand abrasive remains constant within a certain time period, and the particle conveying pipe 222... The size of the end opening is proportional to the discharged quartz sand abrasive particles, achieving a quantitative supply of abrasive particles. The abrasive particles ultimately fall into the left-end feed hopper of the electric screw conveyor 23. The microcontroller 8 directs the electric screw conveyor 23, causing the screw inside to rotate, transporting water and quartz sand abrasive particles. During transport, the water and quartz sand abrasive particles are mixed evenly to form a liquid blasting medium, which then flows into the storage bin 24 through the output port. The blasting medium is then transported forward through the conveying pipe 25, with a slurry pump 26 connected in series in the middle of the conveying pipe 25 providing power for the medium transport. The front end of the conveying pipe 25 penetrates the rear wall of the blasting machine housing 1 and is connected to the spray gun 3 via a stainless steel flexible hose 4. The stainless steel flexible hose 4 is flexible and allows the operator to adjust the angle of the spray gun 3.The operator inserts both hands through the symmetrically distributed glove ports 7 on the front side wall of the sandblasting machine housing 1, puts on gloves inside the ports 7, and reaches into the equipment. Holding the spray gun 3 located inside the sandblasting machine housing 1, the operator presses the control button 9 at the front of the spray gun 3 handle. The control button 9 sends a start signal to the slurry pump 26. After pressurization, the slurry pump 26 delivers the sandblasting medium in the delivery pipe 25 through the stainless steel hose 4 to the spray gun 3. The operator manipulates the spray gun 3 to spray the workpiece surface on the stainless steel mesh 5, achieving surface treatments such as rust removal, deburring, and polishing. Waste generated during the operation falls through the mesh of the stainless steel mesh 5 to the bottom of the sandblasting machine housing 1, and finally exits through the discharge port 6 at the lower end of the sandblasting machine housing 1.
