[0002] Sandblasting machine is a kind of air conveying machine. It uses compressed air to transport powdered granular materials from one place to another in a pipeline. In the process of converting kinetic energy into potential energy, the high-speed moving sand particles scour the surface of the object, thereby improving the surface quality of the object.

[0003] However, after the existing six-axis sandblasting machine uses sand to scour the surface of an object, the scour dust and tiny sand particles as well as the residues produced by the scouring object will mix with each other. After long-term use, a large amount of dust, sand particles and residues will accumulate inside the equipment. If they are not cleaned in time, it will affect the operation of the equipment. Therefore, how to solve this problem is what we need to consider. Utility Model Content

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-Figure 4 A six-axis manipulator sandblasting machine includes a sandblasting machine body 1, a supporting leg is arranged at the lower end of the sandblasting machine body 1, and an anti-skid pattern is arranged at the lower end of the supporting leg, and the anti-skid pattern is wavy. A shell 2 is fixedly connected to one side of the sandblasting machine body 1, a dust removal chamber 3 is arranged in the shell 2, and a filter chamber 4 is arranged in the shell 2. The dust removal chamber 3 is connected with the filter chamber 4 through a through port 5. The bottom of the dust removal chamber 3 is conical, and the through port 5 is located at the axis of the dust removal chamber 3. A control valve is arranged in the through port 5. When spraying water, the dust removal chamber 3 is connected to the filter chamber 4 through a through port 5. The opening 5 is closed at the right time, and then opened after the end. A strip plate 6 is fixedly connected to the top of the dust removal chamber 3. The strip plate 6 is a hollow structure. A plurality of water outlets 7 are opened at the lower end of the strip plate 6. A first filter plate 8 is rotatably connected to the dust removal chamber 3. Water is sprayed through the plurality of water outlets 7, so that the floating dust will freely fall onto the first filter plate 8 after contacting the water. Since the dust has a certain degree of adhesion, it will adhere to the first filter plate 8, and will also adhere to the first filter plate 8 after the water dries up.

[0022] Among them, a first motor 9 is installed on the outer wall of the shell 2, and the first motor 9 is a servo motor. The output shaft of the first motor 9 extends to the inside of the dust removal chamber 3 and is fixedly connected to the first filter plate 8. A second filter plate 10 that can slide freely up and down is provided in the filter chamber 4. By starting the first motor 9, the first filter plate 8 is driven to rotate and tilt left and right, so that sand and part of the debris fall onto the second filter plate 10. A driving mechanism for driving the second filter plate 10 to move up and down is provided inside the filter chamber 4. The driving mechanism includes two abutment rods 11 fixedly connected to the lower end of the second filter plate 10. The lower end surfaces of the two abutment rods 11 are both arc surfaces. Rectangular plates 12 are fixedly connected to the inner walls on both sides of the filter chamber 4. The two abutment rods 11 The two levers 11 are respectively provided with springs 13 on their outer walls, and the two ends of the two springs 13 are elastically connected to the lower end of the corresponding second filter plate 10 and the upper end of the rectangular plate 12, respectively. A transmission shaft 14 is rotatably connected between the inner walls of both sides of the filter chamber 4, and two cams 15 are fixedly connected to the outer wall of the transmission shaft 14, and the two cams 15 are in contact with the lower ends of the corresponding levers 11. A second motor 16 is installed on the outer wall of the housing 2, and the output shaft end of the second motor 16 extends to the inside of the filter chamber 4 and is fixedly connected to one end of the transmission shaft 14. Through the cooperation of the levers 11, the springs 13 and the cams 15 and other structures, the second filter plate 10 moves up and down to filter the sand and debris.

[0023] Among them, a third filter plate 17 is fixedly connected in the filter chamber 4, a water storage box 18 is placed at the inner bottom of the filter chamber 4, a water pump 19 is installed on the outer wall of the shell 2, and the water inlet end of the water pump 19 is connected to two water inlet pipes 20, one of which is connected to the water storage box 18, and the other is connected to the external water tank. Solenoid valves are arranged in the two water inlet pipes 20, and the water outlet end of the water pump 19 is connected to the interior of the strip plate 6 through the water outlet pipe. The filter holes of the third filter plate 17 can only pass water, so the water will fall into the water storage box 18 and can be recycled by the water pump 19 for the next spraying. A fan 21 is installed at the upper end of the shell 2, and the air inlet end of the fan 21 is connected to the interior of the sandblasting machine body 1 through the air inlet pipe, and the air outlet end of the fan 21 is connected to the interior of the dust removal chamber 3 through the air outlet pipe. A sealing door 22 is installed on one side of the shell 2, and the sealing door 22 is a transparent door, and the situation inside the shell 2 can be observed through the sealing door 22.

[0024] In the utility model, when in use, the staff first starts the fan 21. After the fan 21 is started, the dust, sand particles and debris inside the sandblasting machine body 1 will be sucked into the dust removal chamber 3. At this time, the staff can start the water pump 19 to pump water into the strip plate 6 and spray the floating dust through multiple water outlets 7. The dust will increase in weight when it contacts the water and fall onto the first filter plate 8. At this time, the staff can open the control valve in the port 5 and then start the first motor 9. After the first motor is started, it will take the first filter plate 8 with it. The plate 8 is tilted left and right. Since dust has a certain adsorption when it is wet, it will be directly adsorbed on the surface of the first filter plate 8. In addition, when the water dries, it will also be fixed on the first filter plate 8. However, sand particles have no adsorption and directly fall onto the second filter plate 10 through the rotation of the first filter plate 8. In this process, some debris will adhere to the first filter plate 8, and some debris will fall onto the second filter plate 10 with the sand particles. The dust and some debris can be separated by the cooperation of the strip plate 6, the first filter plate 8 and the water pump 19.

[0025] Then the staff can start the second motor 16. After the second motor 16 is started, it will drive the transmission shaft 14 to rotate, and then drive the two cams 15 to rotate. During the rotation process, when the two cams 15 contact the corresponding push rods 11, the second filter plate 10 and the push rod 11 will be pushed up. When the two cams 15 are separated from the corresponding push rods 11, under the elastic action of the spring 13, the second filter plate 10 and the push rod 11 move down, so that the lower ends of the two push rods 11 continuously resist the corresponding cams 15 and move up and down with the rotation of the corresponding cams 15, thereby making the second filter plate 10 move up and down to filter the sand and debris thereon, and the sand that meets the specifications will fall onto the third filter plate 17. After standing for a period of time, the staff can open the sealing door 22, take out the sand that meets the specifications for recycling, and the sprayed water will fall into the water storage box 18 through the third filter plate 17, which can be recycled for the next spraying and dust removal.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
