This pipeline is mainly used for producing various specifications of UPVC pipes for agricultural water supply and drainage, building water supply and drainage, municipal water supply and drainage, and power cable protection. The equipment consists of a conical twin-screw extruder, mold, vacuum forming table, traction machine, cutting machine, expansion machine, flipping rack, etc. The extruder and tractor adopt imported AC variable frequency speed regulation devices, and the vacuum pump and tractor motor are all high-quality brands. There are traction methods such as two claws, three claws, four claws, six claws, eight claws, ten claws, twelve claws, etc. Cutting can be done using saw blades or planetary cutting methods, and can also be equipped with length and thickening devices. The unit has reliable performance and high production efficiency. → There are cone double extruders and flat double extruders to choose from. By changing some units, pipes such as M-PVC, C-PVC, inner wall spiral pipes, inner wall hollow pipes, and core foam pipes can be produced. → There are options for saw blade cutting machines and planetary cutting machines. Small caliber has two options: one out of two and one out of four. The PVC/UPVC/CPVC ID16mm-ID630mm series PVC pipe extrusion production line is mainly used for the production of agricultural water supply and drainage, building water supply and drainage, cable laying, and other aspects. The SJZ51/105 or SJZ65/132 conical twin-screw extruder is used as the main machine for producing two PVC/UPVC/CPVC, and is equipped with a double tube single control stainless steel spray molding machine. This avoids the waste phenomenon of adjusting one tube and affecting the other tube during production. The automatic single control dual traction machine and cutting machine are integrated with the previous dual shaping technology, making the operation more flexible. The double tube extrusion diameter ranges from 16-63, which can fully utilize the extrusion capacity of the extruder, and even the production of small-diameter pipes can achieve extremely high output. Purpose and characteristics of four PVC/UPVC/CPVC: the first mock examination four PVC line pipe and water supply pipe production line can reduce the equipment input cost, plant input cost and production input cost, and greatly increase the output. Using a double cone 65 mainframe, one out of four molds, one out of four cooling and shaping tables, one out of four traction machines, one out of four cutting machines, and one out of four flipping racks.
