Specifically, the inclined roller 1701 is inclined towards the turning roller 7 at an angle θ at an end far away from the forming table 23, the first paper tape 4 is wound on the inclined roller 1701 through the turning roller 7, the paper surface of the first paper tape 4 is attached to the peripheral surface of the inclined roller 1701 under tension, that is, the first paper tape 4 is always kept perpendicular to the central axis of the inclined roller 1701, so that the inclined angle at which the first paper tape 4 is shifted from the turning roller 7 to the inclined roller 1701 is also θ, the distance between the turning roller 7 and the inclined roller 1701 is d', and the first paper tape 4 is shifted by a distance:
d=d’*tanθ
therefore, the deviation size of the first paper tape 4 is detected by the paper tape deviation size detection device 24 and is fed back to the control system of the equipment, the control system automatically controls the motor to adjust the movement of the inclined roller 1701, the size of the distance d' between the inclined roller 1701 and the steering roller 7 is changed, automatic deviation correction is realized, and the accuracy of merging of the first paper tape 4 and the second paper tape 5 is ensured.
It can be appreciated that, since the third paper tape 6 is located at the outer side and needs to be adjusted inwardly, the inclined roller 1701 on the path of the third paper tape 6 is inclined away from the end of the forming table 23 facing away from the turning roller 7 by an angle θ, so that the third paper tape 6 is offset and converged with the second paper tape 5 by a certain width, and the adjusting principle is the same as that described above, and detailed description thereof is omitted.
The paper tube forming process of the embodiment comprises the following steps: the first paper tape 4, the second paper tape 5 and the third paper tape 6 which are discharged from the three paper feed trays 2 are fed back under the traction of the paper feed rollers 3, and are subjected to tension adjustment by a tension adjustment mechanism; the three paper tapes are divided into three paths by a steering roller 7, wherein after the second paper tape 5 is napped by a napping device 14, a first gluing device coats a first adhesive on one surface of the second paper tape; the second paper tape 5 is converged with the second paper tape 5 after being regulated by the offset regulating mechanism 17, and is pressed and bonded by the first pressing device 18; simultaneously, after the third paper tape 6 is subjected to offset adjustment through the other offset adjustment mechanism 17, the third paper tape and the second paper tape 5 bonded with the first paper tape 4 are respectively wound around the other several steering rollers 7, are alternately laminated and converged, and are bonded through the second bonding device 19; after the paper tape is curled into a tubular paper tape by the forming device 8, the tubular paper tape is conveyed by the conveying device, dried and solidified by the heating device 22, and finally cut at the cutting device 9 to form a three-layer paper tube.
Therefore, the continuous forming laminated three-layer paper tube processing equipment is provided with the automatic paper feeding disc device, the first gluing device, the second gluing device, the forming device and the cutting device, wherein the automatic paper feeding disc device is provided with three paper feeding discs, three paper tapes are synchronously discharged, gluing is carried out on two sides of the second paper tape through the first gluing device and the second gluing device, the first paper tape and the third paper tape are combined and bonded in a staggered manner, the forming device curls the paper tapes into a tubular paper tape, the cutting device cuts the tubular paper tape into three layers according to a certain length, and then the continuous forming processing of the paper tube is realized, so that the requirements of higher-strength paper tubes can be met, the conditions such as bending and shrinking of the paper tube are not easy to occur, the efficiency is very high, the cost is reduced, the surface of the produced paper tube is smooth, the consistency of the paper tube is higher, and the quality of the paper tube is ensured.
