Embodiment Construction

[0044] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0045] Glossary explanation: A direction refers to clockwise or counterclockwise.

[0046] Example, a vacuum calibrator such as figure 1 As shown, including a cylindrical box body 1, a sealing cover will be installed at both ends of the box body 1, and the sealing cover can be locked on the box body 1 by buckling or other methods. Of course, the sealing cover can freely open and close the box body 1 ; Through the sealing effect of the sealing cover, the box body 1 will form a sealed chamber.

[0047] The end of the box body 1 is used for feeding the pipe body 2. The delivery roller 3 is installed in the box body 1. The delivery roller 3 supports the pipe body 2. The pipe body 2 is vacuum-shaped in the box body 1 and passed through the spray head. After the water of 81 is cooled, the pipe body 2 will still be pulled out of the box body 1 along the conveying ...

Abstract

The invention discloses a vacuum molding box and solves the problem that lots of spraying water exists in subsequent processing because water flow is retained on the wall of a pipe if molding is implemented after water cooling when a molding device adopts a spraying mode in use. The vacuum molding box comprises a long cylindrical box body and a sprayer which is arranged inside the box body; a conveying roller used for conveying a pipe body is arranged inside the box body; a wiping roller is arranged inside the box body; the axis of the wiping roller is parallel to the axial direction of the box body; the wiping roller leans against the outer wall of the pipe body positioned inside the box body; the wiping roller is fixedly provided with rotating blades; a pneumatic component used for blowing the rotating blades to rotate and driving the wiping roller to rotate toward a direction A is arranged inside the box body; the outer wall of the pipe body is wiped by a rotating shaft of the wiping roller; and thus the water flow on the surface of the pipe body is reduced.

Description

technical field [0001] The present invention relates to a plastic pipe forming equipment, more specifically, it relates to a vacuum calibrating box. Background technique [0002] The vacuum setting machine is a special equipment for cooling and shaping the pipe. Its purpose is to provide a vacuum environment for the formed pipe, and to cool down and shape the pipe in this vacuum environment, so that the pipe can form a fixed shape. [0003] In the existing vacuum setting machine, the PVC material needs to be cooled and shaped after being extruded by the extruder, so as to ensure the quality of subsequent products. A Chinese patent document with publication number CN205685713U is now retrieved. Its name is a vacuum setting machine, which is shaped in a negative pressure, and the setting device adopts a spray method, and is formed after water cooling. When in use, because the water flow will stay in the On the pipe wall, there is a large amount of spray water in the subsequen...
