Description

Technical Field

[0001] This utility model relates to the field of sandblasting machines, and in particular to a multi-station sandblasting structure and a sandblasting machine. Background Technology

[0002] In the field of sandblasting machines, multi-station design is one of the key directions for improving the efficiency of workpiece sandblasting. Currently, mainstream multi-station sandblasting machines generally use several mounting seats for clamping workpieces fixed on a rotatable turntable. Each mounting seat is equipped with an independent drive motor, which directly drives the mounting seat and workpiece to rotate, so that the workpiece surface can fully contact the sandblasting airflow to achieve a uniform sandblasting effect. However, this traditional structure has significant technical defects and cost pain points: 1. To ensure that the workpieces at each workstation can rotate stably, each mounting base needs to be matched with an independent motor and corresponding transmission and control components, which leads to a significant increase in the hardware procurement cost of the equipment. Especially in scenarios with a large number of workstations (such as 8 or 12 workstations), the cost of motors and supporting components can account for 30%-50% of the total equipment cost, putting a heavy upfront investment pressure on manufacturing companies.

[0003] 2. The extensive use of independent motors increases the structural complexity of the equipment. Not only does it require more installation space to accommodate the motors and wiring, but it also increases the difficulty of assembling the equipment and the cost of later maintenance (such as the need to check and replace each motor individually when it fails, which is inefficient and expensive). At the same time, the cumulative energy consumption generated by the operation of multiple motors will also lead to a significant increase in the long-term operating cost of the equipment.

[0004] Therefore, there is an urgent need for a multi-station sandblasting structure and sandblasting machine to solve the above problems. Utility Model Content

[0020] Reference Figures 1-3 This utility model provides a multi-station sandblasting structure, including a revolution frame 10, a first drive assembly 20, a second drive assembly 30, a spray gun assembly 40, and several self-rotating frames 50. The rotating frame 50 is circumferentially arranged on the revolving frame 10, and the workpiece 60 is mounted on the rotating frame 50; The output end of the first drive component 20 is connected to the orbiter 10 and is used to drive the orbiter 10 to rotate around its own axis. The output end of the second drive component 30 is connected to several self-rotating frames 50, and is used to drive the self-rotating frames 50 to rotate around their own axes. The spray gun assembly 40 is located around the circumference of the rotating frame 10 and is used for sandblasting the workpiece 60.

[0021] Reference Figures 1-3 In this utility model, the sandblasting structure is applied to a sandblasting machine. The sand recovery device on the sandblasting machine provides sand to the spray gun assembly 40. Multiple workpieces 60 to be sandblasted are mounted one by one on the rotating frame 50. During sandblasting, the first drive assembly 20 and the second drive assembly 30 are started simultaneously. The first drive assembly 20 drives the revolution frame 10 to rotate around its own axis, and the second drive assembly 30 simultaneously drives several rotating frames 50 to rotate around their own axes. During this process, when the revolution frame 10 revolves, it will drive all the workpieces 60 to pass through the spray gun assembly 40 in sequence. At the same time, the rotation of the rotating frame 50 enables the outer wall of the workpiece 60 to be fully sandblasted by the spray gun assembly 40 when it passes through the spray gun assembly 40, thus achieving simultaneous sandblasting of multiple workpieces 60.

[0022] Reference Figures 1-3In some embodiments, the first drive assembly 20 includes a first motor 21 and a first reducer. The input end of the first reducer is connected to the output end of the first motor 21, and the output end is connected to the orbital frame 10. The power output by the first motor 21 is reduced by the first reducer to drive the orbital frame 10 to rotate, which can prevent the orbital frame 10 from rotating too fast.

[0023] Reference Figures 1-3 In some embodiments, the second drive assembly 30 includes a second motor 31, a second reducer 32, and a synchronous belt 33. The input end of the second reducer 32 is connected to the output end of the second motor 31. The synchronous belt 33 is sleeved on the output end of the second reducer 32 and several rotating frames 50. The power output by the second motor 31 is reduced by the second reducer 32 and drives the synchronous belt 33 to rotate. The synchronous belt 33 is connected to some of the rotating frames 50. With the rotation of the orbital frame 10, all the rotating frames 50 can be connected to the synchronous belt 33 in sequence, thereby realizing that the synchronous belt 33 drives all the rotating frames 50 to rotate at the same time.

[0024] Reference Figures 1-3 In some embodiments, the spray gun assembly 40 includes a first mounting base 41, a second mounting base 42, a first bearing 43, a second bearing, a rotating shaft 44, and a plurality of spray guns 45. The first mounting base 41 and the second mounting base 42 are mounted on the frame and are arranged on both sides of the revolving frame 10. The first bearing 43 is disposed on the first mounting base 41, and the second bearing is disposed on the second mounting base 42. The rotating shaft 44 passes through the first bearing 43 and the second bearing and is connected to an external drive device. The spray guns 45 are mounted on the rotating shaft 44. Specifically, the first mounting base 41 and the second mounting base 42 are mounted on the frame of the sandblasting machine. The rotating shaft 44 is connected to the first bearing 43 and the second bearing, and then connected to the drive device. The drive device drives the rotating shaft 44 to swing back and forth, thereby driving the spray guns 45 to swing back and forth in the vertical direction. In other embodiments, the spray gun assembly 40 is configured as multiple groups and arranged at intervals in the vertical direction, thereby realizing the sandblasting treatment of the rod-shaped workpiece 60 and improving the sandblasting efficiency.

[0025] Reference Figures 1-3In some embodiments, the rotating frame 50 includes a first rotating seat 51, a second rotating seat 52, a pressure plate 53, and an elastic element 54. The first rotating seat 51 is rotatably disposed at the upper end of the orbital frame 10, and the second rotating seat 52 is rotatably disposed at the lower end of the orbital frame 10 and opposite to the first rotating seat 51. The pressure plate 53 is mounted on the first rotating seat 51 via the elastic element 54. The workpiece 60 is confined between the pressure plate 53 and the second rotating seat 52. The output end of the second drive assembly 30 is connected to the second rotating seat 52. Specifically, during installation... First, the upper end of the workpiece 60 is brought into contact with the pressure plate 53 and pushed upward, so that the elastic element 54 is compressed. Then, the lower end of the workpiece 60 is mounted on the second rotating seat 52, and the elastic element 54 continuously applies clamping force to the workpiece 60. In a further embodiment, the upper end surface of the second rotating seat 52 is provided with a slot 71, and the pressure plate 53 is provided with a rubber coating layer 72. The lower end of the workpiece 60 is inserted into the slot 71, which can prevent the workpiece 60 from disengaging from the second rotating seat 52. The upper end of the workpiece 60 is held against the rubber coating layer 72. Relying on the high coefficient of friction of the rubber coating layer 72 and the elastic force of the elastic element 54, the upper end of the workpiece 60 and the pressure plate 53 maintain a good contact effect.

[0026] This utility model also provides a sandblasting machine, including the aforementioned sandblasting structure.

[0027] The advantages of this invention are: by using the second drive component to simultaneously drive the synchronous rotation of all the self-rotating frames, there is no need to configure a separate motor and supporting components for each workstation. With the same number of workstations, not only can the number of drive motors be greatly reduced, thereby significantly reducing hardware procurement costs, but the wiring and assembly process of the equipment is also simplified, further reducing production and assembly costs and significantly enhancing the market competitiveness of the equipment.

All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
