Description

Technical Field

[0001] This invention relates to the technical field of hot melt integral molding processing equipment for plastic pipe fittings of different diameters, specifically a hot melt integral molding processing equipment suitable for plastic pipe fittings of different diameters. Background Technology

[0002] The plastic pipe fitting thermofusion molding processing device is used to connect two plastic pipe fittings. The thermofusion pipe fitting is a general term for PE pipe fittings that are connected by thermofusion, including injection molded socket thermofusion pipe fittings, injection molded butt thermofusion pipe fittings, and welded thermofusion pipe fittings.

[0003] For example, CN221496797U discloses a hot-melt device for plastic pipe fittings, comprising a worktable, an electric telescopic rod, and side plates. A support plate is installed at the rear end of the upper surface of the worktable, a support plate is installed inside the support plate, a fixing plate is installed above the support plate, and a threaded rod is installed inside the fixing plate. Slide grooves are formed on both the left and right sides of the upper surface of the worktable, and protective plates are installed inside the slide grooves. A connecting rod is installed at the end of the electric telescopic rod, and a hot-melt cylinder is installed on the right side of the connecting rod. An electromagnetic slide rail is installed at the upper end of the side plates, and a clamp is connected to the output end of the hydraulic rod. This hot-melt device for plastic pipe fittings features an arc-shaped support plate and cover plate, which can conform to the outer surface of the pipe for easy fixing. The movable hot-melt cylinder eliminates the need for manual operation, preventing burns and increasing automation. The protective plate also provides protection, preventing workers from accidentally touching the hot-melt cylinder.

[0004] Existing multi-pipe systems are all injection molded, and their pipe diameter is determined by the mold. Therefore, when used for non-standard multi-pipe connections or small-scale trials, the mold cost is relatively high. Furthermore, they cannot be used for free combinations of different pipe diameters. The plastic pipe feeding process is not stable enough and the feeding is not convenient enough, which affects the efficiency of hot melting.
