Technical Field

[0001] The utility model belongs to the technical field related to the production of vibration screen meshes, and particularly relates to a mesh welding device for vibration screening equipment. Background Art

[0002] Vibrating screen is a kind of equipment used for material screening, which is widely used in mining, building materials, transportation, energy, chemical industry and other industries. Its main function is to separate materials according to different particle sizes through vibration, so as to achieve the functions of material classification, washing, dehydration, and de-mediuming. In the vibrating screen, an exciter is usually used to excite vibration to drive the material on the screen to vibrate for screening. In the production process of the screen, the screen and the screen frame need to be welded together by a welding device, but it still has the following disadvantages in actual use:

[0003] During the welding process of the vibration screen welding device, the vibration screen components are directly placed on the welding position and welded after alignment. However, during operation, the operator needs to carefully align the components on the screen and the screen frame, which is troublesome to operate.

During the welding process, the welding position is easily disturbed and deviated, resulting in welding defects. Utility Model Content

When the support plate is working, it is movably connected to the screen body through the movable opening. The screen body is movably connected in the movable opening to prepare for screening. The telescopic end of the lifting cylinder is rotatably connected with a rotating pressure plate.

[0008] Furthermore, the screening component also includes a screen frame, the fixing ring is movably connected between the limiting blocks, and the screen frame is fixed to the top of the fixing ring, so that the structure of the screening component is fixed on the supporting plate.

[0009] Furthermore, the rotating pressure plate is arranged on the top of the screen frame, and the bottom end of the rotating pressure plate abuts against the screen frame, so that the lifting cylinder restricts the screen frame.

[0010] Furthermore, the bottom end of the welding head is arranged at the inner ring edge of the fixing ring, and a mounting plate is fixed to the upper part of the outer side of the welding head, and the welding head is mounted on the external lifting and moving structure through the mounting plate.
