Description

Technical Field

[0001] The utility model belongs to the technical field of dust bag processing, in particular to a multi-station welding device for dust bag processing. Background Art

[0002] The main function of the dust bag skeleton is to provide structural support for the bag so that it can maintain a stable shape during operation and is not easily deformed or collapsed. A good skeleton design can ensure that the filter material (such as filter cloth) inside the bag remains tight, avoiding the displacement or wrinkling of the filter material due to external pressure, which affects the filtering effect. The skeleton usually needs to have high temperature resistance and corrosion resistance, because the dust bag may be exposed to high temperature gas or corrosive substances in actual application. Commonly used metal materials include galvanized steel, stainless steel, etc.

[0003] However, when welding the dust bag frame, the frame is composed of multiple steel rings and straight steel wires. The common welding method is to manually put the steel wire on the mold fixing frame and then put the steel ring on the steel wire. Due to the large number of welding stations, multiple people are required to cooperate with the rotating fixing frame. After welding a steel wire, it is rotated once, which results in a long time consumption and low processing efficiency. Utility Model Content

Since the horizontal slider 33 in the slide groove 31 is threadedly connected to the threaded rod 32, the rotation of the threaded rod 32 drives the horizontal slider 33 to move along the thread, driving the limit ring 34 and the internal fixed component to move. The limit ring 34 acts as a rotation limit for the two fixed rings 35, and the elastic reset of the second spring 38 is used to drive the two fixed rings 35 to clamp one end of the steel wire in several fixing holes 36, completing the fixation of the steel wire, facilitating the adjustment of the positions of multiple welding stations in conjunction with the rotating mechanism 2, better completing welding, and improving processing efficiency.
