Description

Honeycomb refill drawing mechanism many times

Technical Field

The utility model relates to an improved invention of honeycomb board processing equipment, in particular to a mechanism for stretching a honeycomb paper core for multiple times.

Background

The speed of honeycomb paper core processing and honeycomb cardboard processing has the difference, and the two parts process separately, have so both shortened the length of honeycomb cardboard production line, can improve production efficiency again, reduction in production cost. The honeycomb paper cores produced by the honeycomb paper core machine are collected, stacked and stored in a unified mode, when the honeycomb paper boards are processed, the stacked honeycomb paper cores are pulled apart into honeycomb boards, and the honeycomb boards and the face paper are compounded to form the honeycomb boards.

Traditional honeycomb refill draws open mechanism adopts a pair of roller pressfitting tensile, and the rotational speed of preceding roller is faster than the rotational speed of back roller, draws open the refill through the speed difference. Because of refill broad width broad, the length of required roller is longer, and roller surface machining has the error just big, and pressure inequality can appear during the pressfitting, leads to tensile inhomogeneous, and some are tensile excessive, and the broad width of honeycomb refill narrows down, and tensile not enough then the broad width is too big, and the honeycomb holes of the honeycomb refill after the design warp, can not reach required broad width, finally leads to honeycomb cardboard to lack core or multicore, increases the rejection rate and increases the loss.
