Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of PERT production molds, and specifically relates to a PERT granulation vertical production mold. Background Technique
[0002] PERT, that is, high-temperature resistant polyethylene, is a pipe material used in systems such as floor heating and hot water supply; the PERT granulation production mold is a device component designed specifically for producing PERT particles. These molds are usually installed at the end of an extruder or granulator and are used to shape the molten PERT material into particles of specific size and shape.
[0003] The modified polyethylene granulation device disclosed in the patent application with the reference publication number CN217373011U includes: a protective shell, a feed pipe assembly is arranged on one side of the protective shell, and a hydraulic cylinder is installed at the upper end of the protective shell; a support assembly arranged inside the protective shell, the horizontal height of the upper end of the support assembly is adaptively arranged with the horizontal height of the feed pipe assembly; a granulation assembly located inside the protective shell and fixed to the telescopic end of the hydraulic cylinder, the granulation assembly is directly above the support assembly; several groups of drive motors installed on the side wall of the protective shell, one end of the output shaft of the drive motor penetrates the protective shell and is fixedly connected with a conveying roller, and a rubber anti-slip sleeve is sleeved on the outer wall of the conveying roller. This utility model drives the conveying roller to rotate by the drive motor for feeding, and then drives the granulation assembly to cut the linear modified polyethylene material by the hydraulic cylinder. Compared with the existing granulation methods, it avoids the generation of irregularly shaped pellets, and thus avoids the blockage of the subsequent injection molding process.
[0004] As shown in the above-mentioned prior art, most of the existing polyethylene granulation production molds have an inclined surface for discharging at the discharge port, so that the material strip forms an angle of 45° with the ground when discharging. In this way, the material strip is easily broken and the overlapping of the material strips is inconvenient; the existing polyethylene granulation production molds usually send the material strip into cold water for water cooling, and continuously transporting the high-temperature material strip into cold water without taking measures to quickly cool the cold water will affect the cooling effect of the material strip and affect the subsequent granulation process.
[0005] Therefore, it is necessary to provide a PERT granulation vertical production mold to solve the above technical problems. Content of the Utility Model
