Description

Technical Field

[0001] This utility model relates to the technical field of wet sandblasting machines, specifically a planetary rotary table type wet sandblasting machine. Background Technology

[0002] Sandblasting machines use compressed air as power to create a high-speed jet that propels abrasive materials (steel grit, quartz sand, corundum, glass sand, resin sand, etc.) onto the surface of the workpiece, altering its mechanical properties. Due to the impact and cutting action of the abrasive materials, the workpiece surface achieves a certain level of cleanliness and varying roughness, improving its mechanical properties. This enhances fatigue resistance, increases adhesion between the workpiece surface and coatings, extends coating durability, and facilitates paint leveling and decoration. Sandblasting removes impurities, discoloration, and oxide layers from the workpiece surface, while simultaneously roughening the surface, eliminating residual stress, and increasing surface hardness.

[0003] Traditional sandblasting equipment uses ordinary belt drive to keep the spray gun stationary while the workpiece rotates for sandblasting. During the rotation, the ordinary belt will slip, resulting in uneven coating on the product surface, which affects the product quality. In addition, the workpiece needs to be cleaned after sandblasting, which wastes a lot of water resources.

[0004] Therefore, a planetary rotary table wet blasting machine is proposed to address the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a planetary rotary table wet sandblasting machine, including a sandblasting machine main unit. A wastewater treatment structure is provided on one side of the main unit. A sandblasting chamber is opened inside the main unit. A rotary table structure is provided on one side inside the sandblasting chamber. A rotation structure is provided on the outer side of the rotary table structure. A spray gun lifting mechanism is provided on one side of the rotary table structure. A cleaning nozzle is positioned opposite the spray gun lifting mechanism. A water mist removal structure is provided above the rotary table structure. A grinding fluid chamber is provided below the sandblasting chamber. A sand-water agitator and a low water level sensor are provided on one side of the grinding fluid chamber. A grinding fluid pump is provided on one side of the grinding fluid chamber. The grinding fluid pump is connected to a grinding fluid rod below. A lower connecting fork is provided on one side of the grinding fluid rod. One side of the lower connecting fork pipe is connected to the sand-water ratio display and sand-water mixer via a branch pipe. The other side of the lower connecting fork pipe is connected to the main connecting pipe via a branch pipe. The upper connecting fork pipe is connected to the upper connecting fork pipe above. One side of the upper connecting fork pipe is connected to the sandblasting head located below the lifting mechanism via a branch pipe. The other side of the upper connecting fork pipe is connected to the sand-water separator via a branch pipe. A sewage discharge pipe is located at the bottom of the grinding chamber. The sewage discharge pipe is connected to a second sewage discharge valve. A first sewage discharge valve is located below the sewage treatment structure. A sludge cart is located at the bottom of the sewage treatment structure. One side of the sewage treatment structure is connected to a water pump via a pipe. The other end of the water pump is connected to a precision filter via a pipe. The precision filter is connected to a cleaning nozzle via an inlet pipe.

[0006] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0007] This utility model, by setting up a second drive motor, a second rotating shaft, a first pulley, a second pulley, and a synchronous belt, transforms the belt from a traditional ordinary belt into a synchronous belt. This solves the slippage problem caused by increased resistance during rotation, making the transmission smoother, the sandblasting more uniform, and improving product quality.

[0008] This invention incorporates a sand-water separator and a precision filter. Wastewater is separated by the sand-water separator, and the separated wastewater is sent into the wastewater treatment structure. After being pumped out and filtered a second time by the precision filter, the wastewater is sent to the cleaning nozzle through the inlet pipe and used as circulating water, thus saving water resources.

[0032] Specifically, the turntable structure 9 includes a turntable body 94, which is rotatably mounted on the support frame 27. The turntable body 94 is connected to a rotating shaft 93 at its lower end, and the rotating shaft 93 is connected to an intermittent divider 92 at its lower end. One side of the intermittent divider 92 is connected to a drive motor 91.

[0033] Specifically, the self-rotating structure includes three pulleys 20 located at the three corners of the turntable body 94 on the same plane. The three pulleys 20 are rotatably mounted at the three corners above the support frame 27. One of the pulleys 20 has a pulley 21 located on the side of the turntable body 94. The pulley 21 is connected to the drive motor 22 via a rotating shaft 2. The three pulleys 20 and the pulley 21 are rotatably connected by a synchronous belt 19. The drive motor 22 drives the rotating shaft 2 to rotate, which in turn drives the pulley 21 to rotate. The pulley 21 then drives the synchronous belt 19 to rotate, which in turn contacts the product and causes the product to rotate.

[0034] Working principle: The product is placed on a special fixture above the turntable body 94. Drive motor 91 is started, which drives rotating shaft 93 to rotate. Rotating shaft 93 drives the turntable body 94 to rotate. The rotation stops after the intermittent divider 92 detects the final rotation position. At this time, drive motor 22 drives rotating shaft 2 to rotate, which in turn drives pulley 21 to rotate. Pulley 21, via synchronous belt 19, drives pulley 20 to rotate. During this rotation, synchronous belt 19 causes the product to rotate. Simultaneously, servo motor 206 drives the sliding assembly to slide down. The downward movement causes the lifting rod 28 to descend, which in turn causes the sandblasting head 216 to descend. The sandblasting head 216 performs sandblasting. The spray distance and pressure are adjusted by the spray gun lifting mechanism 2. After sandblasting, water is sprayed out through the cleaning nozzle 10 to wash off the large sand particles on the product surface. The wastewater is separated by the sand-water separator 17. The separated wastewater is sent into the wastewater treatment structure. The separated sludge is sent to the sludge cart below. The separated water is pumped out by the water pump 7 and sent to the precision filter 8 for secondary filtration. After secondary filtration, the water is sent to the cleaning nozzle 10 through the water inlet pipe 23 for use as circulating water, thus saving water resources.
