Technical Field

[0001] This utility model relates to an engraving machine, and more particularly to a negative pressure mobile circulating sandblasting engraving machine. Background Technology

[0002] Vibration during engraving machine movement, prolonged disuse, or high moisture content in the diamond abrasive can all cause abrasive caking. Changes in the abrasive absorption environment can lead to a lack of abrasive output or unstable abrasive output, affecting the engraving machine's efficiency. Therefore, it is necessary to improve the engraving machine to achieve stable abrasive output. Utility Model Content

[0003] This invention aims to at least partially solve one of the technical problems in related technologies. To this end, this invention proposes a negative pressure mobile circulating sandblasting and engraving machine.

[0005] The air compressor is connected to an oil-water separator, and the oil-water separator is connected to a sandblasting gun via a sandblasting high-pressure air pipe. The sandblasting gun is located inside the engraving operation box.

[0006] The bottom of the intermediate body of the sand box is provided with a conical sand collection pool. The oil-water separator is also connected to the conical sand collection pool through a material disturbance high-pressure air pipe.

[0019] like Figure 1 and Figure 2 The negative pressure type mobile circulating sandblasting and engraving machine shown includes an air compressor 1, a sand box intermediate body 2, and an engraving operation box 3.

[0020] The air compressor 1 is connected to the oil-water separator 4, and the oil-water separator 4 is connected to the sandblasting gun 6 through the sandblasting high-pressure air pipe 5. The sandblasting gun 6 is located inside the engraving operation box 3. The sandblasting gun 6 in this application is a siphon-type negative pressure sandblasting gun.

[0021] The bottom of the sand box intermediate body 2 is provided with a conical sand collection pool 7. The oil-water separator 4 is also connected to the bottom of the conical sand collection pool 7 through a material disturbance high-pressure air pipe 8. A high-pressure air switch 9 is provided on the material disturbance high-pressure air pipe 8.

[0022] The bottom end of the conical sand collection tank 7 is connected to the sandblasting gun 6 via the sandblasting gun suction pipe 10. The sandblasting gun suction pipe 10 in this application is equipped with a sand suction volume regulating valve 11; the air compressor 1, the sand box intermediate body 2, the engraving operation box 3, and the oil-water separator 4 in this application are all mounted on a mobile vehicle.

[0023] This utility model discloses a negative pressure mobile circulating sandblasting engraving machine. An air compressor 1, an oil-water separator 4, a sandblasting gun 6, a high-pressure air switch 9, and a sand suction volume regulating valve 11 form a high-pressure negative pressure siphon engraving system. The high-pressure air generated by the air compressor 1 is split into two paths after passing through the oil-water separator 4. One path enters the sandblasting gun 6 through the sandblasting high-pressure air pipe 5. When the negative pressure siphon-type feeding sandblasting gun 6 sprays air, it generates negative pressure to suction sand. The air and sand mix in the sandblasting gun 6 to form an air-sand mixture. When ejected, it forms a high-pressure, high-speed air-sand mixture fluid for engraving. The work involves another material disturbance. The high-pressure air pipe 8 enters the conical sand collection pool 7 to disturb the diamond abrasive. Due to the addition of gas, the diamond abrasive caking is resolved, and the density of the diamond abrasive is reduced, allowing it to become a fluid that enters the sandblasting gun. This ensures stable sand output from the engraving machine and guarantees the engraving efficiency of the engraving machine. The sand suction volume is controlled by the sand suction volume regulating valve 11 on the sandblasting gun suction pipe 10. The regulating principle is to add an appropriate amount of air into the sand suction pipe 10 to interfere with the sand suction volume, thereby enabling the sandblasting gun to spray a stable air-sand fluid for engraving operations.

[0024] The specific application scenarios of the high-pressure air switch in this application are as follows: 1. Before carving, the high-pressure air switch 9 is turned on, and high-pressure air is sprayed out from the bottom of the conical sand collection pool 7, impacting the diamond abrasive and increasing its fluidity. That is, the high-pressure gas impacts and disturbs the diamond abrasive in the conical sand collection pool 7, causing it to collide with each other, making the diamond abrasive smoother and more fluid. 2. When the sandblasting gun 6 does not produce abrasive, the high-pressure air switch 9 is turned on to disturb the diamond abrasive in the conical sand collection pool 7, changing the diamond abrasive environment in the conical sand collection pool 7, making the diamond abrasive smoother and more fluid. 3. If the abrasive output is not smooth during carving and other methods cannot solve the problem, the high-pressure air switch is turned on to add a small amount of high-pressure air, causing air bubbles to form inside the diamond abrasive, reducing the density of the diamond abrasive, and allowing it to become a fluid that enters the sandblasting gun, facilitating the negative pressure siphon suction of the sandblasting gun.

[0025] Theoretically, the larger the sand suction capacity of the sandblasting gun, the smoother the operation should be. However, in actual work, it often happens that the sand suction tube 10 of the sandblasting gun is full of sand, but the sandblasting gun 6 cannot spray any sand. The reasons are: 1. Siphoning is a negative pressure, with low pressure, and the high density of diamond sand cannot be sucked up; 2. The sandblasting gun 6 is designed to have a small flow rate of diamond sand entering the sandblasting gun, which does not allow more diamond sand to enter, causing the diamond sand to clog the sandblasting gun and not be sprayed out. The solution is to install a sand suction regulating valve 11 on the sand suction tube 10 of the sandblasting gun. The sand suction regulating valve 11 is specifically an adjustable air valve. The principle is to add an appropriate amount of air into the sand suction tube 10 of the sandblasting gun. The amount added should be tested and adjusted when starting the machine, so that the diamond sand sucked in by the sandblasting gun under negative pressure becomes a "mixture fluid of air and diamond sand". After reducing the density, the fluidity is increased, which greatly improves the working efficiency of sandblasting and engraving. After the sand suction regulating valve is adjusted to the optimal state, the equipment does not need to be adjusted again during use unless there are changes in the usage factors.

[0026] In a preferred embodiment, the top of the sand box intermediate body 2 in this application is connected to a dust collection bag 16 via a fan 15, and the engraving operation box 3 and the sand box intermediate body 2 are connected via a sand return pipe 12. The sand box intermediate body 2 is equipped with a diamond abrasive baffle 13 and a diamond abrasive filter 14, with the diamond abrasive baffle 13 located above the diamond abrasive filter 14, and the aperture of the diamond abrasive baffle 13 being smaller than the aperture of the diamond abrasive filter 14.

[0027] The diamond abrasive screen 13 and the diamond abrasive filter screen 14 are spaced apart to form an intermediate body A. The intermediate body A has a sand return hole 202 on the side near the carving operation box 3, facilitating connection between the carving operation box 3 and the sand return hole 202 via the sand return pipe 12. A feed inlet 201 is provided on the other side of the intermediate body A. More preferably, the diamond abrasive screen 13 in this application is 50 mesh, and the diamond abrasive filter screen 14 is 30 mesh. The sand box intermediate body 2, the conical sand collection pool 7, the carving operation box 3, and the dust collection bag 16 in this application form a low-pressure negative pressure material recovery and separation system. Specifically, the negative pressure generated by the blower 15 draws the diamond abrasive from the operating box 3 into the intermediate body A through the return hole 202. Since the feed port 201 is located between the diamond abrasive baffle 13 and the diamond abrasive filter 14 (diamond abrasive baffle 13 is 50 mesh and diamond abrasive filter 14 is 30 mesh), the negative pressure generated by the blower 15 draws the diamond abrasive from the engraving operating box 3 into the intermediate sand box. The diamond abrasive in the intermediate sand box has three destinations: dust smaller than 50 mesh is discharged from the intermediate sand box and enters the dust collection bag 16; dust larger than 50 mesh is discharged; and dust larger than 50 mesh is discharged. 0-mesh or smaller (less than 30 mesh) diamond abrasive enters the conical sand collection tank 7 under gravity, while impurities larger than 30 mesh remain in the intermediate body and are removed through the feed port 201. The diamond abrasive sucked out of the conical sand collection tank 7 by the sandblasting gun 6 falls into the operation box 3 after being sprayed out. The diamond abrasive falling into the operation box 3 is sucked back into the sand box intermediate body 2 by the fan 15 and the sand return pipe 12. After separation and dust removal, it falls back into the conical sand collection tank 7, realizing the recycling of diamond abrasive. This makes the sandblasting and engraving operation continuous, stable, and reliable, saving resources and reducing waste.
