[0002] Sandblasting is a common treatment process for metal rust removal or oxide layer removal. It uses compressed air as the power to form a high-speed jet beam to spray abrasive materials (garnet sand, copper ore sand, quartz sand, emery, iron sand, Hainan sand) onto the surface of the workpiece to be treated at a high speed, thereby removing the rust or oxide layer on the surface of the metal workpiece.

[0003] Before painting metal workpieces, sandblasting is usually used to remove the rust or oxide layer on their surfaces to improve the adhesion of paint. In existing sandblasting equipment, for example, the 9090W wet liquid sandblasting machine currently in use on the market, an operation port is provided on the front side of the sandblasting chamber. The operator holds the workpiece and inserts it into the operation port. The sand pump sprays the liquid mortar onto the surface of the workpiece at a high speed. At the same time, the operator continuously turns the workpiece to perform sandblasting on various parts of the workpiece surface.

[0004] However, this operation method has low efficiency and requires the operator to maintain concentration at all times, resulting in a relatively high labor intensity for the operator. Therefore, it needs to be improved. Content of the Utility Model

Among them, both the mortar tank 3 and the sand pump 4 adopt the existing technologies in the field. The mortar tank 3 is used to hold liquid sand materials, the sand pump 4 pumps out the liquid sand materials and sends them to the sandblasting mechanism 5, and finally sprays them out at high speed through the sandblasting mechanism 5.

[0029] An opening 21 is provided at the front side of the sandblasting chamber 2, a funnel-shaped discharge port 22 is provided at the bottom of the sandblasting chamber 2, and a maintenance door 23 is also provided on one side of the sandblasting chamber 2.

[0030] The positioning mechanism 6 is arranged at a position in the sandblasting chamber 2 in front of the sandblasting mechanism 5, and the positioning mechanism 6 can slide into / out of the sandblasting chamber 2 along the opening 21.

[0031] As Figure 4 shown, the sandblasting mechanism 5 includes a first linear module 51 and a sandblasting gun 52. The first linear module 51 is arranged along the longitudinal direction on the inner wall at the rear side of the sandblasting chamber 2. The sandblasting gun 52 is slidably connected to the first linear module 51, and the sandblasting gun 52 is connected to the sand pump 4 through a hose 7.

[0032] The end of the sandblasting gun 52 is connected to the slider 54 of the first linear module 51 through a rotating seat 53. A bolt 55 is provided at the connection between the rotating seat 53 and the sandblasting gun 52. The bolt 55 fixes the sandblasting gun 52 on the rotating seat 53, and the inclination angle of the sandblasting gun 52 can be adjusted through the bolt 55. The specific operation method is as follows: First, loosen the bolt 55, then rotate the sandblasting gun 52 to the required angle, and then tighten the bolt 55.

[0033] An accordion cover 56 is also arranged outside the first linear module 51 to prevent sand materials from entering the inside of the first linear module 51.

[0034] The positioning mechanism 6 includes a second linear module 61, a sliding plate 62, a baffle 63, and a rotating assembly. The second linear module 61 is arranged along the horizontal direction at the bottom of the sandblasting chamber 2. The sliding plate 62 is slidably connected to the second linear module 61. The baffle 63 is arranged along the longitudinal direction at the front side of the sliding plate 62, and the area of the baffle 63 is larger than the area of the opening 21, so as to seal the sandblasting chamber 2.

[0035] The rotating assembly is arranged on the sliding plate 62, as Figure 5As shown in the figure, the rotating assembly includes a shield 64, a turntable 65, a driving motor 66, a worm gear 67 and a worm 68. The shield 64 is arranged on the top of the slide plate 62. The turntable 65 is rotatably arranged on the top of the shield 64. The driving motor 66 is arranged inside the shield 64. The worm gear 67 is coaxially arranged at the bottom of the turntable 65 and is drivingly connected to the driving motor 66 through the worm 68.

[0036] On both sides of the bottom of the slide plate 62, there is a telescopic guide rail 69 respectively. The fixed section of the telescopic guide rail 69 is fixedly arranged at the bottom of the sandblasting chamber 2, and the movable section of the telescopic guide rail 69 is fixedly arranged at the bottom of the slide plate 62. The telescopic guide rail 69 plays an auxiliary supporting role for the slide plate 62.

[0037] Similarly, structures such as the second linear module 61 and the telescopic guide rail 69 can also be protected from dust by using a bellows.

[0038] On the slide plate 62, at the position outside the shield 64, there are several slag discharge holes 610. The slag discharge holes 610 are used to let the ejected abrasive fall to the lower part and be discharged from the discharge port 22.

[0039] The working principle of the present utility model is as follows:

[0040] First, the second linear module 61 is controlled to act through the control switch 8 arranged on the outer wall of the sandblasting chamber 2, so that the slide plate 62 and the rotating assembly are moved out of the sandblasting chamber 2. The staff places the workpiece on the turntable 65, and then the positioning mechanism 6 is returned to its position by operating the control switch 8.

[0041] Subsequently, the staff operates the control switch 8 again to make the sandblasting mechanism 5 start to work. The first linear module 51 drives the sandblasting gun 52 to move up and down reciprocally. At the same time, the driving motor 66 drives the turntable 65 to rotate slowly, ensuring that each surface of the workpiece can face the side of the sandblasting gun 52. With the up and down reciprocating movement of the sandblasting gun 52 and the rotation of the workpiece, the workpiece is fully sandblasted.

[0042] After the processing is completed, operate the control switch 8 to stop the sandblasting mechanism 5 from working, and the turntable 65 stops rotating. Then, the positioning mechanism 6 is moved out of the sandblasting chamber 2, and the staff takes out the workpiece and puts in a new workpiece to be processed.

[0043] By operating in this way repeatedly, continuous sandblasting of the workpiece is realized, and the staff does not need to perform any operations during the sandblasting process, which not only reduces the labor intensity of the staff, but also improves the sandblasting efficiency of the workpiece.

[0044] It should be noted that: the parts not specifically described in the specification do not fall within the protection scope of the present utility model, nor are they related to the improvement of its structure or function. For example, the waste gas purification during the sandblasting process, the collection and treatment of waste materials after sandblasting, the electrical connection mode between the control switch 8 and the sandblasting mechanism 5 and the positioning mechanism 6, etc. all adopt the existing technologies or the conventional technical means in this field, and will not be elaborated here.

[0045] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those skilled in the art can implement them; when the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present utility model.
