Description

Technical Field

[0001] This utility model relates to the field of shot blasting machine technology, specifically a suspended shot blasting machine. Background Technology

[0002] Suspended shot blasting machines are used when processing steel structure workpieces. These machines are commonly used for surface treatment and cleaning. They suspend the workpiece on a lifting device, and a high-speed rotating impeller sprays shot blasting agent onto the workpiece surface to remove oxide layers, rust, welding slag, oil, and other impurities, thus achieving cleaning and finishing. Suspended shot blasting machines are suitable for surface treatment of workpieces of various shapes and sizes. They offer advantages such as fast cleaning speed, good cleaning effect, low energy consumption, and simple operation, and are widely used in various manufacturing industries.

[0003] Currently, Chinese utility model patent CN220260662U discloses a suspended shot blasting machine for steel structure workpieces, including a machine body and a mounting frame. The lower surface of the mounting frame has a sliding groove. A first servo motor is fixedly connected to the outer wall of the front end of the mounting frame. A threaded rod is fixedly connected to the output end of the first servo motor. A threaded sleeve is fitted around the threaded rod, and a second servo motor is fixedly connected to the lower surface of the threaded sleeve. In this utility model, when the suspended shot blasting machine for steel structure workpieces needs to load or unload workpieces, the first servo motor drives the threaded rod to rotate, thereby moving the hook back and forth. This replaces manual loading and unloading operations, reducing the labor intensity of workers, improving work efficiency, and also facilitating the placement or removal of workpieces by operators, eliminating the need for any part of their body to reach into the equipment to place or remove workpieces, thus eliminating safety hazards.

[0004] Based on the search of the aforementioned patents and the findings of existing equipment, while the aforementioned equipment can solve the problem of inconvenience in collecting welding slag and dust generated after sandblasting, resulting in poor practical performance, traditional suspended shot blasting machines require operators to extend part of their body into the equipment to place or remove workpieces, posing certain safety hazards. Furthermore, during use, a single hook can only suspend one workpiece for shot blasting at a time, leading to a long processing cycle, significantly slowing down the overall production progress, making it difficult to meet the pace of large-scale production, and increasing production and time costs.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a suspended shot blasting machine, comprising a shot blasting machine body, a mounting frame, a servo motor, a screw, a movable seat, hooks, and a support rod. The mounting frame is fixedly installed on the inner wall of the shot blasting machine body. The servo motor is fixedly connected to the left side of the mounting frame. The screw is fixedly connected to the output end of the servo motor. The movable seat is threadedly connected to the surface of the screw.

A limiting slip ring is movably connected to the inner wall of the annular seat, and the bottom of the limiting slip ring is fixedly connected to the top of the mounting plate.

[0009] As a preferred embodiment of this utility model, both the large gear and the small gear are fitted with protective covers, which are fixedly connected to both sides of the inner wall of the movable seat.

[0010] In a preferred embodiment of this invention, a support disc is fixedly connected to the surface of the rotating rod, and the surface of the support disc is movably connected to the inner wall of the fixed disc.

[0011] As a preferred embodiment of this utility model, both sides of the inner wall of the fixed disk are provided with arc-shaped grooves, and both sides of the supporting disk are movably inlaid with balls.

[0019] like Figures 1 to 4 As shown, the present invention provides a suspended shot blasting machine, including a shot blasting machine body 1, a mounting frame 2, a servo motor 3, a screw 4, a movable seat 5, a hook 6, and a support rod 7. The mounting frame 2 is fixedly installed on the inner wall of the shot blasting machine body 1. The servo motor 3 is fixedly connected to the left side of the mounting frame 2. The screw 4 is fixedly connected to the output end of the servo motor 3. The movable seat 5 is threadedly connected to the surface of the screw 4. The hook 6 is set at the bottom of the mounting frame 2, and there are five sets of hooks 6. The support rod 7 is set at the bottom left side of the mounting frame 2. A fixed plate 8 is fixedly connected to the bottom of the movable seat 5. A rotating rod 9 is movably connected to the inner wall of the fixed plate 8. A mounting plate 10 is fixedly connected to the bottom of the rotating rod 9. The bottom of the mounting plate 10 is fixedly connected to the top of the hook 6. A drive assembly 11 is fixedly connected to the right side of the top of the fixed plate 8. A limit assembly 12 is fixedly connected to the bottom of the fixed plate 8.

[0020] refer to Figure 2 and Figure 3 The drive assembly 11 includes a drive motor 111, which is fixedly connected to the right side of the top of the fixed disk 8. A small gear 112 is fixedly installed on the top of the drive motor 111, and a large gear 113 is meshed with the left side of the small gear 112. The large gear 113 is fixedly connected to the top of the rotating rod 9.

[0021] As a technical optimization of this utility model, by setting the drive component 11, the drive motor 111 can drive the small gear 112 to rotate, which in turn drives the large gear 113 and the rotating rod 9 to rotate. The rotating rod 9 drives the mounting plate 10 to realize the active rotation of the hook 6, so that all surfaces of the workpiece can be fully treated by shot blasting, thereby further improving the uniformity and quality of shot blasting.

[0022] refer to Figure 2 and Figure 4 The limiting component 12 includes an annular seat 121, which is fixedly connected to the bottom of the fixed plate 8. A limiting slip ring 122 is movably connected to the inner wall of the annular seat 121, and the bottom of the limiting slip ring 122 is fixedly connected to the top of the mounting plate 10.

[0023] As a technical optimization of this utility model, by setting the limiting component 12, the limiting slip ring 122 can rotate on the inner wall of the annular seat 121, so that the limiting slip ring 122 can play a limiting role during the rotation of the hook 6, ensuring the stable rotation of the mounting plate 10 and the hook 6, preventing them from shaking or deviating during rotation, ensuring the stability of the equipment operation, and indirectly improving the accuracy of shot blasting.

[0024] refer to Figure 3 and Figure 4 The surfaces of both the large gear 113 and the small gear 112 are fitted with protective covers 13, which are fixedly connected to both sides of the inner wall of the movable seat 5.

[0025] As a technical optimization of this utility model, by setting a protective cover 13, the protective cover 13 on the surface of the large gear 113 and the small gear 112 can prevent shot from splashing onto the surface of the large gear 113 and the small gear 112 during the shot blasting process, avoid wear and damage to the large gear 113 and the small gear 112, and extend the service life of the large gear 113 and the small gear 112.

[0026] refer to Figure 3 and Figure 4 A support disc 14 is fixedly connected to the surface of the rotating rod 9, and the surface of the support disc 14 is movably connected to the inner wall of the fixed disc 8.

[0027] As a technical optimization of this utility model, by setting a support disc 14, the support disc 14 on the surface of the rotating rod 9 can be movably connected to the inner wall of the fixed disc 8, providing additional support for the rotating rod 9, enhancing the stability of the rotating rod 9 during rotation, reducing the shaking of the rotating rod 9, making the hook 6 rotate more smoothly, and improving the shot blasting effect.

[0028] refer to Figure 3 and 4 Both sides of the inner wall of the fixed disk 8 are provided with arc-shaped grooves 15, and both sides of the supporting disk 14 are movably inlaid with balls 16. The number of balls 16 is set in several groups and is distributed in a ring at equal distances. The surface of the balls 16 is movably connected to the inner wall of the arc-shaped grooves 15.

[0029] As a technical optimization of this utility model, by setting the arc groove 15 and the ball bearings 16, the arc groove 15 on the inner wall of the fixed disk 8 and the ball bearings 16 on both sides of the supporting disk 14 can cooperate with each other, reducing the friction between the supporting disk 14 and the fixed disk 8, making the rotating rod 9 rotate more smoothly, reducing the energy consumption of the drive motor 111, and further improving the stability of the rotating rod 9.

[0030] Reference 3 and Figure 4A warning light 17 is fixedly mounted on the surface of the mounting plate 10, and a control panel 18 is fixedly connected to the left side of the support rod 7. The control panel 18 is electrically connected to the warning light 17 through wires.

[0031] As a technical optimization of this utility model, by setting up a control panel 18 and a warning light 17, when the hook 6 is suspending the workpiece for moving operation, the control panel 18 can control the warning light 17 to light up. The obvious light emitted by the warning light 17 forms a conspicuous warning area around the mounting plate 10, effectively reminding the surrounding staff that there is a suspended workpiece that is moving here, avoiding collisions due to negligence, and improving the safety of the shot blasting process.

[0032] The working principle and usage process of this utility model are as follows: First, the workpieces to be shot-blasted are suspended on five sets of hooks 6, ensuring a secure suspension. Then, the servo motor 3 is started, and the screw 4 at the output end of the servo motor 3 rotates, driving the moving seat 5, which is threaded onto its surface, to move. Next, the moving seat 5 drives the bottom fixed plate 8, rotating rod 9, mounting plate 10, and hooks 6, transporting the suspended workpieces to the shot-blasting area inside the shot-blasting machine body 1. Upon reaching the shot-blasting area, the drive motor 111 starts, driving the pinion 112 to rotate. The pinion 112 drives the large gear 113, causing the rotating rod 9 and mounting plate 10 to rotate the five sets of hooks 6. This ensures that all surfaces of the workpiece are evenly shot-blasted during the shot-blasting process, improving the shot-blasting effect. Furthermore, the five sets of hooks 6 significantly increase the number of workpieces that can be shot-blasted in a single operation compared to the traditional single-hook design, thus shortening the processing cycle. Simultaneously, the shot-blasting device inside the shot-blasting machine body 1 is activated, and the high-speed rotating impeller sprays the shot blasting agent onto the rotating workpiece surface, effectively blasting the workpiece. The workpiece undergoes comprehensive shot blasting. During this process, the limiting slip ring 122 rotates on the inner wall of the annular seat 121, limiting the rotation of the hook 6 and preventing it from wobbling or deviating during rotation. This ensures the stability of the equipment operation and the accuracy of the shot blasting process. The support disc 14 provides additional support for the rotating rod 9, enhancing rotational stability. At the same time, the arc groove 15 on the inner wall of the fixed disc 8 and the ball bearings 16 on both sides of the support disc 14 cooperate to reduce the friction between the support disc 14 and the fixed disc 8, making the rotation of the rotating rod 9 smoother and reducing the energy consumption of the drive motor 111. When the hook 6 is moving the workpiece, the control panel 18 controls the warning light 17 to illuminate, reminding surrounding personnel to pay attention to safety and avoid collisions, thus improving safety during the shot blasting process. After the shot blasting is completed, the drive motor 111 stops working, the hook 6 stops rotating, the servo motor 3 reverses, and the moving seat 5 moves the processed workpiece out of the shot blasting area. The warning light 17 is turned off, and the worker removes the workpiece, completing one shot blasting process.

[0033] In summary, this suspended shot blasting machine, with its five sets of hooks 6, allows for the simultaneous suspension of five workpieces for shot blasting, compared to the traditional single-hook design. This significantly shortens the processing cycle, improves production efficiency, meets the demands of large-scale production, and reduces production and time costs. Furthermore, the fixed plate 8, rotating rod 9, and mounting plate 10 enable the hooks 6 to rotate, ensuring even shot distribution to the workpieces during the blasting process and enhancing the blasting effect. This solves the problem of a single hook only being able to suspend one workpiece at a time, resulting in a long processing cycle, significantly slowing down overall production, hindering large-scale production, and increasing production and time costs.
