Description

Technical Field

[0001] The present application relates to the technical field of conveying mechanisms, and in particular to a conveying mechanism of a shot blasting machine. Background Art

[0002] A shot blasting machine is a casting equipment that uses a high-speed rotating impeller to accelerate and project blasting materials such as steel shot, steel grit, and aluminum shot onto the surface of the workpiece, removing impurities such as oxide scale, rust, and welding slag from the surface of the workpiece through the impact force. The shot blasting machine structure includes a conveying mechanism for conveying the workpiece.

[0003] At present, the conveying mechanism of the relevant shot blasting machine lacks a mesh conveying structure and relies solely on a conveying roller structure with a large spacing to convey the workpiece, which is not easy to convey small workpieces. In addition, there is a lack of a recovery and separation structure for the shot blasting materials, which makes it difficult for the staff to recycle and process the shot blasting materials. Utility Model Content

[0007] The workpiece is placed on the top of the conveyor belt, and the motor drives the drive shaft to rotate, so that the conveyor belt conveys the workpiece and sends the workpiece into the internal processing of the shot blasting machine. During processing, a large number of steel shots thrown by the shot blasting machine can pass through the groove of the conveyor belt. The protective plates can form protection on both sides of the conveyor belt to prevent the steel shots from flying out. The steel shots and workpiece debris generated during processing fall into the top of the filter screen, and the steel shots can roll out of the device through the filter screen. The fine workpiece debris is filtered out through the filter screen, thereby guiding and separating the steel shots and debris. After the vibration motor is started, it drives the filter screen to vibrate, so that the steel shots can slide out of the device more smoothly after being subjected to the vibration force, while assisting in the screening of steel shots and workpiece debris.

[0008] Preferably, a protective frame is fixedly connected to the inner side of the fixing frame on the top of the vibration motor, and both sides of the protective frame are outward-facing inclined surfaces.

[0009] The protective frame can form protection on the top of the vibration motor and guide the steel shots of the shot blasting machine to prevent the steel shots from falling on the vibration motor and causing damage to the vibration motor.

[0010] Preferably, a guide plate is fixedly connected to one side of the guide frame, and the surface of the guide plate is coated with an anti-oxidation layer.

[0011] The guide plate can guide the steel shot of the shot blasting machine so that the steel shot can be guided into the external steel shot collecting structure.

[0016] In summary, this application has the following beneficial technical effects:

[0017] By using a metal mesh as the conveyor belt, it can support workpieces of various sizes, reducing the limitations of the device without affecting the falling of steel shots. In addition, by using a filter, a guide frame and a vibration motor in conjunction with each other, it can guide and separate the steel shots and debris, preventing the workpiece debris remaining in the steel shots from being circulated and thrown onto the workpiece, causing damage to the workpiece.

The conveyor mesh belt 1 is a metal mesh and can The workpieces of various sizes are supported, the motor 3 is connected to an external power supply, and the motor 3 drives the transmission shaft 8 to rotate after being energized. The transmission shaft 8 is provided with several roots, which can support the conveyor mesh belt 1 and drive the conveyor mesh belt 1 to rotate, so that the conveyor mesh belt 1 can convey the workpiece and send the workpiece into the internal processing of the shot blasting machine. During processing, a large number of steel shots thrown by the shot blasting machine can pass through the groove of the conveyor mesh belt 1. The tops of the two fixed plates 10 are fixedly connected with protective plates 2. The angle between the protective plates 2 and the fixed plates 10 is 140°, which can form protection on both sides of the conveyor mesh belt 1 to prevent steel shots from flying out.

[0025] The bottom of the fixed plate 10 is fixedly connected to the guide frame 5, and the inner side wall of the guide frame 5 is fixedly connected to the connecting plate 402. The top of the connecting plate 402 is fixedly connected to the spring 401. The spring 401 is provided with two groups of four. The top of the spring 401 is fixedly connected to the filter 4. The bottom of the filter 4 is fixedly connected to the fixing frame 1101. The top of the fixing frame 1101 is fixedly connected to the vibration motor 11. The steel shot and workpiece debris generated during processing fall into the top of the filter 4. The filter 4 is tilted to the left with an inclination angle of 40°. The steel shot can roll out of the device through the filter 4, and the fine workpiece debris is filtered out through the filter 4. The guide frame 5 The bottom wall is set at the same 40° inclination angle as the filter 4, which can make the workpiece debris slide out of the device. The staff places the external collection structure on the two sides of the discharge port on one side of the guide frame 5, so that the material falls into the collection structure, and the steel shots and debris are guided and separated. The vibration motor 11 drives the filter 4 to vibrate after being connected to an external power supply, so that the steel shots can slide out of the device more smoothly after being subjected to the vibration force, and at the same time assist in the screening of steel shots and workpiece debris. The interior of the spring 401 has a matching damper, which can reduce the vibration transmitted to other structures of the device by the filter 4, avoiding the overall device being more serious and affecting the transportation stability of the device.

[0029] The implementation principle of the conveying mechanism of a shot blasting machine in the embodiment of the present application is as follows: the workpiece is placed on the top of the conveyor mesh belt 1, the motor 3 drives the transmission shaft 8 to rotate, so that the conveyor mesh belt 1 conveys the workpiece and sends the workpiece into the internal processing of the shot blasting machine. During processing, a large number of steel shots thrown by the shot blasting machine can pass through the groove of the conveyor mesh belt 1, and the protective plate 2 can form protection on both sides of the conveyor mesh belt 1 to prevent the steel shots from flying out. The steel shots and workpiece debris generated during processing fall into the top of the filter screen 4, and the steel shots can roll out of the device through the filter screen 4. The fine workpiece debris is filtered out through the filter screen 4. The bottom wall of the guide frame 5 is set at 40°, the same inclination angle as the filter screen 4, which can make the workpiece debris slide out of the device, thereby guiding and separating the steel shots and debris. After the vibration motor 11 is started, it drives the filter screen 4 to vibrate, so that the steel shots can slide out of the device more smoothly after being subjected to the vibration force, while assisting in the screening of steel shots and workpiece debris. The spring 401 can reduce the vibration transmitted to other structures of the device by the filter screen 4, avoiding that the device as a whole is more serious and affects the conveying stability of the device.
