Description

TECHNICAL FIELD

[0001] The present application relates to the field of winding pipe technology, in particular to a winding pipe variable inner diameter control device. BACKGROUND

[0002] The spiral winding hollow pipe is different from the conventional other pipes such as HDPE double-wall corrugated pipe, HDPE solid-wall pipe, PVC rainwater drainage pipe in forming process, mainly adding a winding process: first, the pipe blank in molten state is shaped into a square pipe, then is rewound on the winding machine, and is bonded on the side of the square pipe by extruding adhesive through the extruding auxiliary machine, and is finally wound and shaped under the action of the pressure roller. Due to the difference in spiral angle of the winding machine, the difference in water temperature in different seasons, the difference in raw materials, the difference in environmental temperature and the like, the inner diameter of the winding pipe of the same specification will have deviation, being too large or too small. The actual control refers to GB / T19472.2-2017 to control the inner diameter of the pipe, and the too large inner diameter is not only not conducive to the control of the cost of the pipe, but also affects the ring stiffness performance of the pipe; the negative tolerance of the numerical value of the inner diameter will directly lead to that the pipe does not meet the requirements of the national standard, and is judged as unqualified product. Therefore, the control of the inner diameter is particularly important. Then, in the current winding pipe production industry, the control of the inner diameter is mainly achieved by adjusting the water temperature, and the actual effect is very limited (the difference is within 3mm), which is not conducive to the control of the inner diameter. Once the inner diameter difference exceeds 3mm, the large disc mold of the winding pipe machine needs to be replaced and adjusted, which is time-consuming and laborious, and when the formula is replaced or other factors fluctuate, the water temperature needs to be adjusted again or the large disc is replaced.

[0003] In order to strictly control the inner diameter of the winding pipe, taking the ID300SN8 winding pipe as an example, the average minimum inner diameter is required to be 294mm according to the national standard GB / T19472.2-2017, that is, the average minimum inner diameter only needs to reach 294mm, and does not need to be too large. In actual operation, if the inner diameter can be strictly controlled between 294-295, it will be very helpful to the control of the cost and the product performance. SUMMARY
