Anti-twisting winding core barrel for winding of water pipe connector PTFE thread seal tape and anti-twisting mechanism of anti-twisting winding core barrel

Abstract

The invention discloses an anti-twisting winding core barrel for winding of water pipe connector PTFE thread seal tape and an anti-twisting mechanism of the anti-twisting winding core barrel, and belongs to the field of building materials. The anti-twisting winding core barrel is mainly suitable for water heating device installation and comprises a winding core barrel body, the center of the winding core barrel body is provided with a central hole, and the two sides of the winding core barrel body are provided with side walls; a hollow setting-out head rotating around the winding core barrel body is arranged between the two side walls and connected to the winding core barrel body through rotary arms movably connected with the winding core barrel body; and the front end of the setting-out head is smaller than the tail end of the setting-out head, and the PTFE thread seal tape is fed from the tail end and discharged from the front end. According to the anti-twisting winding core barrel for winding of the water pipe connector PTFE thread seal tape and the anti-twisting mechanism of the anti-twisting winding core barrel, twisting of the PTFE thread seal tape during using is avoided, construction is convenient, wasting is avoided, meanwhile, materials are saved, and the construction period is shortened.

Description

technical field [0001] The invention belongs to the field of building materials and is mainly suitable for plumbing installation, in particular to an anti-twist core barrel and an anti-twist mechanism for winding raw material tapes of water pipe joints. Background technique [0002] Raw material tape, also known as raw tape, is a white opaque film-like polytetrafluoroethylene product, an auxiliary product commonly used in plumbing installation. The chemical name is polytetrafluoroethylene, and the raw material tape is polytetrafluoroethylene -- a common name for raw material tape. The raw material belt is mainly used at the joints of the hot and cold water supply pipe fittings to enhance the airtightness of the pipe joints, prevent water leakage at the joints, and increase the leak-proof effect of the joints. At present, raw material belts are used in HVAC and water supply and drainage, and their thickness is generally about 1mm. [0003] Raw tape is a novel and ideal seal...

Problems solved by technology

[0004] At present, raw materials are mainly used such as figure 1 In the package shown in the mandrel drum, the raw material tape 2 is wound between the two side walls 102 of the reel core 1; figure 2 Torsional failure occurs in: figure 2 When using the raw material tape 2 to wrap the threaded joint of the water pipe joint 3, a torsion part 201 appears; in this way, it is necessary to smooth the torsion part or remove the torsion part and then re-wrap; and this torsion failure often occurs in actual construction, which brings great inconvenience to the construction. It is very inconvenient, and it is also easy to cause waste
