The clamping plate 7363 moves toward the cross plate 7361 to clamp and fix the frame between the two.

[0112] Working principle:

[0113] When in use, the frame positioning mechanism 7 is used to clamp and fix the frame for welding, and the waste chips generated by welding fall onto the metal mesh 2. Most of the waste chips fall along the mesh holes of the metal mesh 2, and a small part of the waste chips accumulates on the metal mesh 2.

[0114] The moving trolley 4 controls the forward and reverse rotation of the micro motor 43 through the controller 46, and controls the forward and reverse rotation duration of the micro motor 43. Through this control method, the left and right moving trolleys 4 are moved to the middle of the strip wedge-shaped slide 3 and then return to reset; the controller 46 can also control the rotation speed of the micro motor 43, and then control the moving speed of the moving trolley 4, so that the moving trolley 4 moves laterally at a suitable speed, and uses the micro motor 43 to drive the gear plate 44 to rotate. The rotating gear plate 44 meshes with the teeth of the transverse rack 6, and the transverse rack 6 is fixed in use. Through this structure, the moving trolley 4 is driven to move along the transverse rack 6, driving the slag discharge fan assembly 5 to perform mobile blowing on the upper surface of the metal mesh 2, and sweeping off the waste chips that have not fallen off the surface of the metal mesh 2.
