As an improvement of the sand-returning cavity, the handle is arranged on the outer side of the sand-returning cavity, so that the requirement of manual operation can be met.
As an improvement of the invention, a connecting port is arranged on the mechanical arm clamping handle.
As a refinement of the invention, the two straight nozzles are arranged in parallel.
As an improvement of the invention, the sand return cavity is flush with the front end of the air curtain cavity.
As an improvement of the invention, the air curtain air guide sleeve is in a customized shape, can be planar, is specific to a planar workpiece, but can be designed into an arc shape to meet the operation requirement of the arc surface.
The invention has the beneficial effects that:
1) the periphery of the device is separated from a working surface and a non-working surface by a closed air curtain, the air curtain is respectively reflected towards the inner side and the outer side after contacting with a workpiece table, and the inner side is matched with the negative pressure of a recovery cavity to form air flow to carry away sand materials and dust;
2) two standard direct injection gun assemblies are arranged in the device, and sand flow is guided out in a directional mode; the assembly can be quickly replaced and is convenient to maintain
3) A buffer cavity and a matched recovery negative pressure are arranged in the device, and sand flow and dust are recovered on line;
4) the outside is provided with a mechanical arm clamping handle which can be flexibly clamped on various motion mechanisms to realize directional motion and dimension adjustment;
5) this device adopts the design of two spray guns, has improved the operating efficiency.

Detailed Description
The present invention will be further illustrated with reference to the accompanying drawings and specific embodiments, which are to be understood as merely illustrative of the invention and not as limiting the scope of the invention. It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.
This embodiment a double-barrelled spray gun of sandblast sand return dust removal integration non-contact, including sand return chamber 1, air curtain chamber 2, sand return pipe 3, straight nozzle 4, breather pipe 5, robotic arm clamping handle 6, as shown in fig. 3, two straight nozzle 4 parallel arrangement are in sand return chamber 1, sand return chamber 1 is front end open-ended hollow columnar structure, and the cross-section is waist shape, is equipped with air curtain kuppe 8 and air curtain chamber 2 intercommunication on the cross-section, and the straight nozzle direction is the same with sand return chamber length direction, sand pipe connecting piece 7 is connected to straight nozzle 4 rear end, air curtain chamber 2 sets up at sand return chamber 1 outside front end, and air curtain chamber 2 front end is equipped with air curtain kuppe 8, and air curtain chamber 2 rear end is connected with breather pipe 5, and the air supply is connected to breather pipe 5 rear end, sand return pipe 3 intercommunication sand return chamber 1, the vacuum sand return pipe 3 rear end is connected and is inhaled the sand machine.
When the pneumatic sand blasting machine works, a workpiece to be blasted is placed at a proper position at the front end of the spray gun, the distance between the straight nozzle and the workpiece is calculated, iron sand is sprayed out from the straight nozzle 4, the air pipe 5 is ventilated to open the air curtain, as shown in figure 2, the sprayed iron sand is sprayed on the workpiece to splash all around, the sprayed iron sand collides with the air curtain to mix with swirling air flow, the sand return pipe 3 generates negative pressure suction force, the iron sand is sucked into the sand return cavity 1 and then sucked back into the vacuum sand suction machine (dust is also sucked back), in addition, the air curtain is also reflected inwards and outwards after being sprayed on the workbench to separate a working surface from a non-working surface, the iron sand and the dust in the air curtain cannot overflow, the sand flow and the dust can be recycled on line while the sand blasting is ensured, and the working environment is purified.
