Embodiment 1

[0038] Embodiment 1: A continuous winding equipment for pipe with socket socket (see attached figure 1), including a winding unit molding device and a molten material extruder 18, the winding unit molding device includes two forming cages arranged on the same main shaft 1, the right end of the main shaft is the first forming cage 4, and the left end of the main shaft is the second forming cage Cage 7, a variable diameter mold 6 is arranged between the first forming cage and the second forming cage. The variable-diameter mold includes connecting discs on both sides. The two connecting discs are fixed with the main shaft to form a fixed disc 5. There are outwardly expanding outreaching roller shafts connected between the circumferences of the two fixing discs, and the outreaching roller shafts expand outward. Finally, the pipe socket winding part is formed (see attached figure 2 ), the length of the variable diameter die is equal to or greater than the sum of the lengths of th...

Embodiment 2

[0047] Embodiment 2: A continuous winding equipment for pipes with sockets (see attached figure 1 attached figure 2 attached Figure 5 attached Image 6 ), the fixed discs at both ends of the variable diameter mold 6 can move relative to the axis of the main shaft, but cannot rotate relative to the main shaft. A rotating rod is connected between the two fixed disks of the variable-diameter mold, and the rotating rod drives the two fixed disks to approach each other. A short arm 8 is hinged on the fixed plate, and the hinge point is a fixed hinge point 15. The end of the short arm is hinged with an intermediate roller 9, and the hinge point is a swing hinge point 16. The distance between the swing hinge point and the axis of the main shaft is greater than the distance between the fixed hinge point and the The distance between the axis of the main shaft, the line between the fixed hinge point and the swing hinge point is inclined to the axis of the main shaft. When the two ...

Abstract

The invention relates to a continuous winding apparatus and a continuous winding method for pipes with bell and spigot faucets. The continuous winding apparatus and the continuous winding method overcome the disadvantage that bell and spigot faucets of pipes produced by conventional apparatuses cannot realize on-line one-shot molding and need multiple combined molding. The continuous winding apparatus comprises a winding unit molding device and a fused material extruder. The winding unit molding device comprises two molding cages arranged on a same main shaft; a variable-diameter die is arranged between and connected with the two molding cages; each molding cage comprises connection discs which are located at two ends and mutually rotary, and a roll shaft is arranged between and connected with the connection discs; the variable-diameter die comprises connection discs located at two ends, an outwardly extending roll shaft capable of extending outwardly is arranged between and connected with the connection discs, and after extending, the outwardly extending roll shaft forms an inner winding surface for a bell faucet of a pipe. The molding cages are mainly used for winding production and processing of a pipe body, the variable-diameter die can wind the bell faucet after diameter expansion, and continuous winding production of the pipe can be realized through expansion and recovery of the variable-diameter die; and the bell faucet and the spigot faucet realizes on-line one-shot molding, so molding efficiency is improved.

Description

technical field [0001] The invention relates to a pipe production equipment, in particular to continuous winding equipment and a continuous winding method for pipes with sockets, which can continuously and uninterruptedly produce pipes with sockets. Background technique [0002] High-density polyethylene (HDPE) winding structural wall pipes are widely used at home and abroad for rain and sewage drainage pipes. Due to the use of different structural wall designs, this type of pipe has the advantages of saving raw materials, high ring stiffness, and long service life. , stable and reliable quality, convenient connection, good airtightness and other advantages, so it has a strong market potential. [0003] There are many types of structural wall pipes with different sizes and specifications, and different types of structural wall pipes use different production equipment. The equipment products are relatively single, the comprehensive utilization performance of the equipment is...
