Technical Field

[0001] The utility model relates to the technical field of seam closing equipment, in particular to a seam closing device for producing fireproof air ducts. Background Art

[0002] The air duct is a piping system used for air flow control and transmission. It is widely used in various buildings and industrial facilities. It adjusts the direction and flow of air to achieve the distribution, discharge and circulation of indoor air, and plays an important role in providing a comfortable indoor environment and ensuring the smooth progress of the industrial production process. As a type of air duct, the fireproof air duct has good fire resistance. The fireproof air duct is made of thin steel plates, aluminum plates, rigid polyvinyl chloride plates, fiberglass and other composite materials. It is used to transport air and air mixtures. It is mainly used in large squares, subways, hospitals and other places.

[0003] When producing fireproof air ducts, the air ducts need to be seamed. When seaming manually, there are problems such as unstable duct fixation, low seaming efficiency, and unstable seaming quality. The seaming equipment fixes the air duct through an extrusion rod and an extrusion plate, and the fixing effect is not ideal, which causes the fireproof air duct to shake and shift easily during seaming, resulting in reduced seaming effect of the fireproof air duct, causing the user to re-seam the fireproof air duct, which greatly reduces the user's work efficiency. For this reason, we propose a seaming device for the production of fireproof air ducts. Utility Model Content

[0025] Working principle: When the fireproof air duct production joint device is used, the fireproof air duct is placed outside the bracket 1. The telescopic rod 8 can be used to drive the bracket 1 to adjust its height so that the bracket 1 fixes the bottom of the air duct. Then the knob 11 is used to drive the worm gear 13 and worm 12 structure to rotate, thereby driving the screw 14 to rotate, so that the fixed shells 4 on both sides of the screw 14 move away from the bracket 1, and the position of the fixed shell 4 is adjusted.
