Description

Technical Field

[0001] The utility model relates to the technical field of mesh screens, in particular to a mesh screen vibrator component. Background Art

[0002] The working principle of the existing vibrating screen is that the transducer converts the electrical energy of the ultrasonic power source into mechanical energy. It is a screening equipment that uses a mechanical method to make the screen vibrate to screen the material. The vibration is transmitted to the screen frame and then uploaded to the screen surface, causing the screen surface to vibrate vertically with a small high frequency amplitude, and at the same time transmitted to the powder particles, thereby screening the material on the screen. With the large-scale screening machines, the application scope of screening machines is becoming more and more extensive, and various materials can be screened.

[0003] A box-type vibrator elliptical vibrating screen disclosed in the Chinese utility model patent application disclosure CN216965290U has a designed vibration beam and a box-type vibrator mechanism, and the box-type vibrator mechanism is composed of an eccentric block, a transmission shaft and a box structure, so that the overall height of the utility model is lower, the height required for equipment installation is small, and the foundation investment is small. At the same time, the vibration trajectory of the two groups of eccentric blocks is an elliptical vibration, so that the screening efficiency of the utility model is high, and the exciting force is large. The screening equipment model can be made very large, and multiple groups of vibrators can be placed on the vibration beam; through the designed fixed block and fixed end shaft, the eccentric block is sleeved on the fixed end shaft, and then one end of the fixed block is quickly clamped in the card slot to achieve rapid assembly. The assembly is more secure and loosening due to traditional screw assembly is avoided. The designed extrusion spring applies elastic force to the two fixed blocks to ensure that the two fixed blocks are more firmly stuck in the slots of the fixed end shaft and will not fall off. The designed fine-tuning pressure plate and fine-tuning screw can be screwed through the thread to adjust the position of the fine-tuning pressure plate to ensure that when the fixed block of the utility model is not in contact with the eccentric block, the fine-tuning pressure plate is used to achieve compression and fixation, so that the assembly fault tolerance of the utility model is higher. However, the overall structure of the existing mesh screen vibrator assembly is too simple and can only use a single motor to drive the mesh screen to vibrate, resulting in poor screening effect on materials, low working efficiency, and inconvenience in removing materials.
