Description

Technical Field

[0001] The utility model relates to the technical field of pipeline processing, in particular to an axially embedded winding structure wall pipeline forming device and a forming method thereof. Background Art

[0002] In order to prevent the spiral wound tube from cracking, we designed to add an axial snap-in structure (including protrusions and grooves) to the side wall of the profile, and improve the connection between adjacent turns of the spiral wound tube through the axial snap-in structure (traditionally it is just gluing); but this undoubtedly increases the difficulty of forming the spiral wound tube, and it is also necessary to realize the snap connection of the axial snap-in structure during the winding process. For this reason, we have conducted a lot of research, such as CN202310042934.0, an axial snap-in anti-cracking plastic wound tube winding machine, which is designed to use the extrusion of the front and rear side pressure rollers to realize the snap-in of the axial snap-in structure. This structure does not receive good feedback during actual use, and the snap-in effect of the axial snap-in structure cannot be guaranteed. Utility Model Content

[0005] Axial clamping and winding structure wall pipe forming equipment, the forming equipment includes a plurality of winding rollers, a glue injection nozzle, an extrusion wheel and / or an extrusion plate, the winding rollers are arranged in a circle to form an outer circle, a position on the outer circle is the profile inlet, the glue injection nozzle is installed at the profile inlet, and the extrusion wheel and / or the extrusion plate are installed behind the glue injection nozzle; a hot profile enters the outer circle from the profile inlet, advances along the outer circle spirally and is wound into a circle, and adjacent circles are connected by gluing and an axial clamping structure to form a tube blank; the glue injection nozzle is inserted between the first circle of hot profile and the second circle of hot profile, and the extrusion wheel and / or the extrusion plate are against the side of the first circle of hot profile;

[0006] The molding equipment also includes an expander, which is installed at the profile entrance and extends into the groove on the side of the second circle of hot profile to expand the groove on the side of the second circle of hot profile.

[0007] The above technical solution is further refined, the glue outlet of the glue injection nozzle is located at the rear side of the glue injection nozzle end; the expander is a convex block, and the convex block is fixedly connected to the side of the glue injection nozzle.

[0008] The above technical solution is further refined, and the protrusion is forked and Y-shaped.

[0009] The advantages of the utility model are reasonable design and ingenious conception. The expander is used to open the groove opening on the side of the second circle of hot profile, making it easier for glue injection and the protrusions on the side of the first circle of hot profile to enter and fit into the groove on the side of the second circle of hot profile.
