Description

Technical Field

[0001] This invention relates to the field of sandblasting equipment technology, and more particularly to a vibratory sandblasting machine. Background Technology

[0002] Sandblasting is a process that uses compressed air to create a high-speed jet of abrasive material, which is then propelled at high speed onto the surface of the workpiece. This alters the workpiece's appearance or shape. Due to the impact and cutting action of the abrasive on the workpiece surface, it achieves a certain level of cleanliness and varying roughness, thus improving the workpiece's mechanical properties. This enhances the workpiece's fatigue resistance and increases the adhesion between the workpiece surface and the coating, facilitating paint leveling and decoration, and extending the coating's durability. The required abrasive output during sandblasting varies depending on the workpiece.

[0003] In the existing technology, the sand output of a sandblasting machine is usually adjusted by changing the diameter of its sand outlet nozzle or by changing the air pressure of the sandblasting machine. However, changing the diameter of the sand outlet nozzle often requires replacing the nozzle, which is time-consuming, labor-intensive, and inconvenient to adjust. Adjusting the air pressure can easily cause uneven sand output from the nozzle, making it inconvenient to use. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a vibratory sandblasting machine that solves the problems of inconvenient adjustment of sand output and uneven sand output in existing sandblasting machines.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A vent valve, wherein the vent valve is provided with an air source inlet and a first air outlet;

[0008] A sandblasting can is provided with a receiving cavity, a sand outlet nozzle, a first air inlet, and a sand outlet; the first end of the sand outlet nozzle is connected to the receiving cavity, and both the first air inlet and the sand outlet nozzle are connected to the second end of the sand outlet nozzle.

[0009] The first air passage has one end connected to the first air outlet and the other end connected to the first air inlet.

[0010] A vibration device is provided on the first gas path and is used to vibrate and regulate the gas in the first gas path.

[0011] Optionally, the vibratory sandblasting machine further includes a second air passage, and the sandblasting tank is provided with a second air inlet communicating with the receiving cavity, and the air valve is provided with a second air outlet; one end of the second air passage is connected to the second air inlet, and the other end is connected to the second air outlet.

[0012] Optionally, the first air path is provided with a first flow regulator, and the second air path is provided with a second flow regulator.

[0013] Optionally, the vibratory sandblasting machine further includes a first diverter and a third air passage; the first diverter is disposed on the second air passage and positioned between the second air inlet and the second flow regulating component; the first diverter is provided with a diverter outlet; one end of the third air passage is connected to the diverter outlet, and the other end is connected to the sand outlet.

[0014] Optionally, the vent valve is further provided with a pressure reducing valve and a positive pressure gauge connected to the pressure reducing valve, for stabilizing and displaying the air pressure inside the vent valve.

[0015] Optionally, the vibratory sandblasting machine also includes a pressure regulating component, and the vent valve is provided with a third air outlet. The pressure regulating component is connected to the third air outlet and is used to regulate the air pressure inside the vent valve.

[0016] Optionally, the vibratory sandblasting machine also includes a pressure relief component, and the sandblasting tank is provided with a pressure relief port communicating with the receiving cavity. The air outlet of the pressure regulating component and the pressure relief port are both connected to the pressure relief component.

[0017] Optionally, the vibratory sandblasting machine also includes a nozzle connected to the sand outlet.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] This invention provides a vibratory sandblasting machine. In use, the air inlet is connected to an external air source for air supply. Gas entering the vent valve then passes through the first outlet into the first air path. A vibration device adjusts the gas to a preset fluctuation state. This fluctuating gas is then transmitted through the first inlet to the second end of the sand outlet nozzle, creating a pressure difference between the first and second ends. This pressure difference controls the opening and closing of the sand outlet nozzle, meeting sand output control requirements. Sand is then discharged through the outlet for sandblasting. Furthermore, by adjusting the vibration frequency and amplitude of the fluctuating gas, the opening size and duration of the sand outlet nozzle can be adjusted, thereby regulating the sand output and uniformity without replacing the outlet nozzle or adjusting the external air source's inlet pressure. This makes adjusting the sand output and uniformity more convenient. The fluctuating gas also prevents static electricity blockage at the outlet, resulting in smoother and more convenient sand output, facilitating sandblasting operations and improving sandblasting quality.

[0030] Please refer to the attached reference. Figure 1 To be continued Figure 3 This invention provides a vibratory sandblasting machine, comprising:

[0031] Vent valve 2, which is provided with an air source inlet 21 and a first air outlet 22;

[0032] The sandblasting tank 3 is provided with a receiving cavity 31, a sand outlet nozzle 32, a first air inlet 33 and a sand outlet 34; the first end of the sand outlet nozzle 32 is connected to the receiving cavity 31, and the first air inlet 33 and the sand outlet 34 are both connected to the second end of the sand outlet nozzle 32.

[0033] The first air passage 4 has one end connected to the first air outlet 22 and the other end connected to the first air inlet 33.

[0034] Vibration device 5 is installed on the first air passage 4 and is used to vibrate and regulate the gas in the first air passage 4 so that the gas in the first air passage 4 fluctuates and is transmitted according to the preset vibration frequency and vibration amplitude. The vibration parameter values ​​can be selected according to the air intake pressure and the density, particle size and other values ​​of the sand material in the receiving cavity 31 of the sandblasting tank 3.

[0035] According to the above scheme, during use, the air inlet 21 is connected to an external air source for air supply. The gas entering the vent valve 2 then enters the first air passage 4 via the first outlet 22. The vibration device 5 vibrates and adjusts the gas to a preset fluctuation state. This fluctuating gas is then transmitted through the first inlet 33 to the second end of the sand outlet 32, creating a pressure difference between the first and second ends of the sand outlet 32. This allows for the opening or closing control of the sand outlet 32, meeting the requirements for sand discharge control. The sand is then discharged through the sand outlet 34. Sandblasting operation; simultaneously, by adjusting the vibration frequency and amplitude of the fluctuating gas to different values, the opening size and duration of the sand outlet 32 ​​can be adjusted, thereby achieving adjustment of the sand output and uniformity without replacing the sand outlet 32 ​​or adjusting the intake air pressure of the external air source, making the adjustment of the sand output and uniformity more convenient; moreover, the fluctuating gas can also prevent static electricity blockage at the sand outlet 34, making the sand output smoother and more convenient, facilitating the sandblasting operation and improving the sandblasting quality.

[0036] Furthermore, in order to more effectively adjust the sand output to meet the requirements of sandblasting, the vibratory sandblasting machine also includes a second air passage 6, and the sandblasting tank 3 is also provided with a second air inlet 35 that communicates with the receiving cavity 31, and the air valve 2 is also provided with a second air outlet 23; one end of the second air passage 6 is connected to the second air inlet 35, and the other end is connected to the second air outlet 23.

[0037] In this embodiment, by adjusting the gas flow rates of the first air passage 4 and the second air passage 6, the pressure difference inside and outside the receiving cavity 31 can be adjusted, thereby regulating the sand output of the sand outlet 32 ​​to meet the sandblasting requirements of different workpieces. Simultaneously, when the sand outlet 32 ​​is open, sand flows out from it; when the sand outlet 32 ​​is closed, the gas in the first air passage 4 drives the sand to be discharged from the sand outlet 34.

[0038] Specifically, the first air passage 4 is equipped with a first flow regulator 41 to accurately control the gas flow rate of the first air passage 4, and the second air passage 6 is equipped with a second flow regulator 61 to accurately control the gas flow rate of the second air passage 6; thereby meeting the usage requirements of sand output.

[0039] Furthermore, in order to facilitate the rapid discharge of sand from the sand outlet 34 and to adjust the sand output of the sand outlet 32 ​​to meet the requirements of sandblasting, the vibratory sandblasting machine also includes a first diverter 7 and a third air passage 8; the first diverter 7 is located on the second air passage 6 and between the second air inlet 35 and the second flow rate regulator 61; the first diverter 7 is provided with a diverter outlet 71; one end of the third air passage 8 is connected to the diverter outlet 71, and the other end is connected to the sand outlet 34.

[0040] In this embodiment, the gas discharged from the diversion outlet 71 enters the sand outlet 34 through the third air passage 8, thereby adjusting the sand discharge speed at the sand outlet 34, which in turn adjusts the obstruction effect of the sand at the sand outlet 34 on the sand at the sand nozzle 32. Then, through the combined action with the air pressure in the receiving cavity 31, it can also help to adjust the sand discharge volume of the sand nozzle 32.

[0042] In this embodiment, the pressure reducing valve 24 can automatically fine-tune the air pressure in the vent valve 2 so that it remains within the preset pressure range under conditions of minimal fluctuation. Simultaneously, the positive pressure gauge 25 can be connected to an alarm; when the displayed value on the positive pressure gauge 25 is outside the preset range, an alarm signal is issued to alert personnel in a timely manner.

[0043] Furthermore, to facilitate manual adjustment of the pressure value within the vent valve 2 to meet usage requirements, the vibratory sandblasting machine also includes a pressure regulating component 9.

When the pressure value inside the receiving cavity 31 is adjusted to a normal pressure state through the pressure relief port 36 and the pressure relief component 10, the receiving cavity 31 can be automatically filled with sand, thereby facilitating the sandblasting operation.

[0046] Furthermore, in order to facilitate the uniform spraying of abrasive material onto the workpiece to be processed and thus improve the sandblasting quality, the vibratory sandblasting machine also includes a nozzle 11, which is connected to the sand outlet 34.

[0047] Furthermore, the vibratory sandblasting machine also includes a second diverter 12 and a clamp valve 13; one end of the clamp valve 13 is connected to the nozzle 11, and the other end is connected to the sand outlet 34 to control the on / off state between the sand outlet 34 and the nozzle 11, thereby facilitating the commencement and termination of sandblasting operations.
