Description

Technical Field

[0001] The utility model relates to the technical field of pipeline sizing, in particular to a sizing mechanism for pipeline production. Background Art

[0002] Plastic pipes are chemical building materials made of high-tech composites. When producing plastic pipes, the raw materials of the pipes must first be melted, then flow through the mold for preliminary shaping, and then transported to the vacuum sizing box for cooling and shaping, so as to obtain pipes with uniform outer diameter, good cooling effect, and no deformation.

[0003] For example, a Chinese patent with publication number CN220331939U discloses a vacuum sizing box, including a sizing box body, a sizing sleeve is provided at the inlet end of the sizing box body, a discharge hopper is provided at the outlet end of the sizing box body, a sizing structure disposed outside the discharge hopper is provided at the outlet end of the sizing box body, the sizing structure includes a mounting ring, a support rod is provided on the circumference of the side wall of the mounting ring, a hollow plate disposed in front of the discharge hopper is fixed to the end of the support rod, a rectangular frame is symmetrically provided on the side wall of the hollow plate, a slider is symmetrically slidably connected in the rectangular frame, and a sizing roller for preventing pipe deformation is rotatably connected between the sliders;

[0004] The technical solution recorded in this scheme starts the motor to drive the screw to rotate, and under the action of the limit of the slide rail and the screw teeth in the opposite direction of rotation, the sliders are driven to move closer to or away from each other, and the sizing rollers are driven to move closer to or away from each other. The distance between the sizing rollers can be adjusted according to the size of the pipe. It is suitable for sizing pipes of different sizes between the sizing rollers to avoid deformation of the pipe when it is sent out from the discharge hopper after forming. However, when using this scheme, the disassembly, assembly and replacement of the sizing rollers are relatively inconvenient, which affects user use.

[0005] Therefore, in view of this, the existing structure and defects are studied and improved, and a sizing mechanism for pipeline production is provided, in order to achieve a purpose with greater practical value. Utility Model Content
