Background

The cement pipeline is widely applied to urban construction. Such as sewer pipes, flood prevention drainage, action protection pipes and the like. However, the traditional method adopted in the pipe production has the problem of low pipe production efficiency. In order to solve this problem, a large number of vertical production methods have been developed in the known improvements. For example, the pipe-making mould is vertically placed (belonging to a single mould) and fed by a material feeder on an elevated platform. For another example, a vertical pipe-making mode is also adopted, three vertical pipe-making molds are placed on the corresponding mold tables at 120 degrees, and the three-station material conveying machines respectively correspond to the pipe-making molds, so that the pipe-making efficiency is improved compared with a pipe-making mode. Therefore, the common defect of the two vertical pipe making modes is that the height of the material conveying machine is increased along with the longer cement pipeline, so that corresponding auxiliary equipment is increased, the design structure is complex, and the production process is complex and the production cost is increased. Meanwhile, it is also known to have a horizontal cement pipe making machine, which mainly uses a horizontal open-mouth circular pipe mold, in the center of which a rotating core mold with a through hole and rotating rollers installed at both sides of the rotating core mold are placed, when slurry supplied from a supply machine falls on the rotating rollers, the slurry is supplied to the open-mouth circular pipe mold through the rotating rollers, at this time, the rotating core mold is driven to rotate and simultaneously a vacuum pump is started to form negative pressure on the rotating core mold, and water is pumped out through the through hole until the water is molded and then is released. The horizontal cement pipe making machine reduces the configuration of related auxiliary equipment relatively vertically, but still belongs to the production mode of single pipe making, and the pipe making efficiency is also influenced.
