Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of plastic pipe processing, specifically to a spraying box for plastic pipe cooling and shaping processing. BACKGROUND

[0002] Plastic pipe is an important component of chemical building materials, and is widely accepted by users due to its superior performance, hygiene, environmental protection, low consumption and other advantages. It mainly includes UPVC drainage pipe, UPVC water supply pipe, aluminum-plastic composite pipe, polyethylene (PE) water supply pipe, and polypropylene PPR hot water pipe. During the processing of plastic pipes, they are mainly made by hot plastic forming. Therefore, they need to be cooled immediately after forming to solidify and shape the inside and outside. If not cooled in time, the pipe may deform during transmission and processing. The tool commonly used for cooling and shaping plastic pipes is a spraying box.

[0003] To this end, Chinese patent number CN219686526U proposes a spraying box for plastic pipe cooling and shaping processing. Under the action of a large water flow, the pipe will deform slightly. Therefore, a pre-cooling spray pipe is provided. The pipe is uniformly pre-cooled under the action of the pre-cooling spray pipe, and then directly cooled by a large water flow.

[0004] The above technical solution has a preheating function during the cooling and shaping of plastic pipes, which makes the shaping effect better. However, during preheating and subsequent water flushing to accelerate cooling, the transmission of the pipe is not smooth, and the existing spraying box does not have a turnover function for the pipe, which is generally cylindrical, resulting in uneven cooling of the outer surface. If the pipe is turned over at the beginning of preheating, the temperature of the pipe will not be completely reduced, and direct turning over will also cause the pipe to deform, reducing the quality of the cooling and shaping of the device. To this end, the present design proposes a spraying box for plastic pipe cooling and shaping processing. UTILITY MODEL CONTENTS
