Description

Technical Field

[0001] The present application relates to the technical field of sandblasting equipment, and in particular to a nickel mesh sandblasting device. Background Art

[0002] Sandblasting machine is a kind of equipment used for surface treatment of die castings, forgings and other workpieces. It is widely used in metal processing, architectural decoration, automobile maintenance and other fields. By using compressed air, sand is sprayed onto the surface of the workpiece to treat the surface of the workpiece, thereby improving the mechanical properties of the workpiece.

[0003] During the production process of the dense mesh, the sealing surface needs to be sandblasted and cleaned. In the existing sandblasting machine, the nozzle is connected to the swing arm, and the swing arm is installed inside the sandblasting box. The swing arm drives the nozzle to swing back and forth in a vertical plane for sandblasting. Since the nozzle swings back and forth in the vertical plane, the nozzle moves in an arc. When the dense mesh is sandblasted, the distance between the nozzle and various parts of the dense mesh is different. Due to the different distances, the sandblasting effect is different, resulting in uneven sandblasting on the surface of the dense mesh, inconsistent roughness of the surface of the dense mesh, and failure to meet production needs.

[0042] The implementation principle of a nickel mesh sandblasting device in this embodiment is as follows: when sandblasting the dense mesh, the heights of the swing arm 72 and the nozzle 734 are adjusted according to the operation requirements, and then the dense mesh is placed on the conveyor belt 21, the conveyor belt 21 conveys the dense mesh to the inside of the sandblasting box 1, and the nozzle 734 sprays the sand in the sand box 5 onto the surface of the dense mesh. During the sandblasting process, the driving mechanism 71 drives the rotating shaft 74 to drive the swing arm 72 to swing back and forth, and the swing arm 72 drives the nozzle 734 to reciprocate. The swing arm 72 cooperates with the conveyor belt 21 to make the nozzle 734 move to any point on the surface of the dense mesh, thereby realizing the sandblasting operation on the surface of the dense mesh. During the operation, the sand mixed with impurities falls into the recovery component 22 under the conveyor belt 21, and is transported to the circulation lifting mechanism 6 through the recovery component 22. The circulation lifting mechanism 6 lifts the sand and impurities upward and transports them to the cyclone separation mechanism 3. The cyclone separation mechanism 3 separates the sand and impurities. The sand is transported to the sand box 5 through a pipeline for storage for recycling, and the impurities are transported to the backblowing mechanism 4. The backblowing mechanism 4 separates the impurities and stores them.

[0043] In summary, in this application, a nozzle is arranged inside the sandblasting box, and the nozzle is connected to a swing arm that swings in the horizontal direction. The swing arm drives the nozzle to move in the horizontal direction to perform sandblasting on the surface of the dense mesh. The nozzle is spaced in the same manner as the dense mesh during the sandblasting operation. At the same time, the nozzle can be moved to any position on the dense mesh through the swing arm, thereby achieving uniform sandblasting of the dense mesh, improving the quality and accuracy of the dense mesh spraying operation, and improving the operating efficiency. The device has a simple structure and is easy to use. In this application, a lifting and adjusting assembly is arranged on the rotating shaft, and the lifting and adjusting assembly drives the swing arm to move up and down along the rotating shaft to adjust the height of the swing arm and the nozzle. At the same time, the mounting plate and the swing arm are connected through different connecting holes of the connecting plate to adjust the relative height between the mounting plate and the swing arm, so that the nozzle can adjust the height arbitrarily to meet different operating requirements and expand the scope of application of the sandblasting device. Therefore, this application effectively overcomes the various shortcomings in the prior art and has a high industrial utilization value.
