A continuous winding stacked paper square tube forming device

Abstract

The invention discloses a continuous winding laminated type forming device for a paper square tube. The continuous winding laminated type forming device comprises a hollow shaft axially arranged on a rack, a square tube core rod mould penetrating in an inner cavity of the hollow shaft, four planetary rotating mechanisms arranged at the periphery of the hollow shaft and rotating around the hollow shaft, an adjusting device and a drive mechanism, wherein a paper pressing idler wheel mechanism is arranged on each planetary rotating mechanism, the four paper pressing idler wheel mechanisms are used for respectively rolling paper strips winding four surfaces of the square tube core rod mould; the adjusting device is arranged on the four planetary rotating mechanisms for adjusting the distance between the paper pressing idler wheel mechanisms and the surface of the square tube core rod mould; and the drive mechanism is used for driving the four planetary rotating mechanisms to rotate around the hollow shaft and driving the square tube core rod moulds to rotate. The paper square tube manufactured by using the continuous winding laminated type forming device is high in size precision, torsion resistance, adhesion compactness, strength, and hardness, and convenient to demould. In addition, the continuous winding laminated type forming device is capable of replacing square tube core rod moulds in different models so as to manufacture paper square tubes of different sizes.

Description

Technical field [0001] The invention relates to the field of paper square tube production devices, in particular to a continuous winding laminated paper square tube forming device. Background technique [0002] The paper square tube is an environmentally friendly paper packaging material that extends after the paper round tube. It is produced from recycled paper through process steps such as paper loading, glue coating, forming, and cutting. Because the current paper square tube technology is not mature enough, the dimensional accuracy, twisting degree, adhesion tightness, strength, hardness and other aspects can not meet the requirements of use; its production equipment also has complex structure, low production efficiency, and paper square tube yield. Low, high manufacturing cost and other shortcomings. [0003] Although there is currently a Chinese patent authorization announcement number CN101797820B that discloses a spiral square paper tube manufacturing equipment, including ...
