Abstract
The utility model relates to a calender edge thickness control device. It solves the low cooling efficiency of the existing calender hot roller and other technical problems. The calender has a base, and the base is provided with a calender counter roller and a calender hot roller arranged in parallel and corresponding to each other. The edge thickness control device includes a cooling main pipe connected to the compressed air main pipe and arranged at the lower side of the two ends of the calender hot roller. The cooling main pipe is provided with a plurality of cooling branch pipes connected to the cooling main pipe and extending towards the end of the calender hot roller. The cooling branch pipes have gas outlets at one end and are provided with branch control valves. The advantage is that the cooling branch pipes arranged at the two ends of the calender hot roller can ensure the cooling range of the calender hot roller surface and improve the cooling effect. The main pipe control valve and the branch control valve can control the cooling main pipe and the cooling branch pipe, improving the compressed air regulation efficiency.
