Non-stop line changing device for steel skeleton plastic composite pipe production equipment

Abstract

The invention discloses a non-stop weft changing device for steel skeleton plastic composite tube production equipment, and belongs to the technical field of composite tube production. The non-stop weft changing device comprises a weft preparing disc as well as a primary weft clamping device and a secondary weft clamping device which are arranged at one side of a weft disc, wherein the primary weft clamping device comprises a weft clamping mechanism I for clamping one end of a weft on the weft preparing disc, and a drive mechanism; the secondary weft clamping device comprises a weft clamping mechanism II for clamping one end of the weft on the weft disc and a welding slag removal mechanism; the other end of the weft on the weft disc extends to a steel wire gauze forming end to wind througha weft guide assembly; the drive mechanism drives the weft clamping mechanism I to get close to the weft clamping mechanism II and is in butt joint with the weft clamping mechanism II, and is weldedand fixed by a welding gun; and conductive rings which are connected with a power supply are arranged at the outer side of the weft disc and the outer side of the weft preparing disc, so that a powersource is provided for the welding gun, the drive mechanism and the welding slag removal mechanism. The non-stop weft changing device realizes a non-stop weft changing function, improves production efficiency, automatically removes ring-shaped welding slag, reduces the weft blocking risk, and improves steel wire gauze forming quality.

Description

technical field [0001] The invention belongs to the technical field of composite pipe production, and in particular relates to a non-stop line changing device for steel frame plastic composite pipe production equipment. Background technique [0002] The production process of steel skeleton plastic composite pipe should be as continuous as possible to reduce the number of shutdowns. Every shutdown will cause the continuous production of steel-framed plastic composite pipes to produce a section of scrap pipes without polyethylene plastic coating, so the shutdown directly affects the production efficiency and product qualification rate of steel-framed plastic composite pipes, resulting in waste of raw materials. At present, in the wire mesh winding process, when the weft thread on the weft thread reel is exhausted, it is necessary to stop the machine to weld the weft thread joints on the weft thread reel and the wire preparation reel, such as figure 2 shown. This mode of oper...
