Description

Technical Field

[0001] The utility model relates to a packaging device, in particular to a gluing device for a tube reel. Background Art

[0002] During paper core tube production, the winding machine can cause excessive glue on the paperboard surface due to uneven surface conditions or other issues. This can also cause uneven glue distribution in both the vertical and horizontal directions, leading to glue overflow on the paper core tubes. This can lead to substandard quality of the finished tubes and slow winding speeds. When the machine is running at a slow speed, the excess glue on the paperboard surface prevents the finished tubes from drying quickly, causing the tubes to bend and jam. When the machine is running at a high speed, the glue on the paperboard surface is low, preventing the tubes from sticking during forming, resulting in a low pass rate and the need to reduce the winding machine speed. Utility Model Content

[0003] Purpose of the utility model: The purpose of the utility model is to provide a tube reel gluing device that can evenly apply glue and improve vehicle speed and qualified rate.

[0004] Technical solution: The gluing device of the tube reel of the utility model includes a front paper guide roller group, a gluing roller, a gluing groove and a rear paper guide roller group. The gluing roller is provided with a gluing roller glue knife. A gluing knife group is provided between the first paper guide roller and the second paper guide roller of the rear paper guide roller group. The gluing knife group consists of several gluing knives. The gluing knife is movably installed on one side of the gluing surface of the cardboard to control the distance between the blade of the gluing knife and the gluing surface of the cardboard.

[0005] Furthermore, the angle of the glue roller and the glue blade is adjustable. When the tube reel is running at low speed, the angle between the glue roller and the glue blade is reduced to reduce the amount of glue applied to the glue roller, which can cause paper jams. If the glue is applied too much and the paper core is damp, the paper core may bend during the rewinding process, causing jams. The contact force between the glue roller and the glue blade is adjusted to reduce the angle.

[0006] Furthermore, the glue knife is installed perpendicular to the gluing surface of the cardboard.

[0007] Preferably, the glue knife group is composed of a first glue knife and a second glue knife. The contact strength between the first glue knife and the second glue knife and the paper jam is adjusted according to whether the end face incision of the paper core tube is open.

[0008] Preferably, the distance between the first glue knife and the second glue knife is 70-90 mm.

[0009] Preferably, the squeegee is a conical scraper.

[0010] Preferably, the glue roller and the glue knife are square scrapers.

[0011] Preferably, the rotation angle of the glue roller and the glue knife is 1-3 degrees.

[0012] Beneficial effects: Compared with the prior art, the utility model has the following advantages: 1. By arranging double glue knives between the first paper guiding roller and the second paper guiding roller, the utility model can better control the uniformity of the glue amount on the sizing surface of the cardboard, improve the speed of the pipe winding machine, improve the qualification rate of the paper core tube, and reduce the production cost; 2. By adding a glue knife for the sizing roller in front of the sizing roller, which can adjust the angle between the glue knife and the sizing roller, the utility model can control the glue amount applied by the sizing roller.

[0015] Figure 3 It is a schematic installation diagram of the glue knife for the sizing roller. Detailed Embodiment

[0016] The technical solution of the utility model will be further described below with reference to the drawings.

[0017] A glue application device for a pipe winding machine according to the utility model comprises a front paper guiding roller group, a sizing roller 1, a glue tank 3 and a rear paper guiding roller group. The sizing roller 1 is provided with a glue knife 2 for the sizing roller with an adjustable angle. A glue knife group is arranged between the first paper guiding roller 4 and the second paper guiding roller 5 of the rear paper guiding roller group. The glue knife group consists of a first glue knife 6 and a second glue knife 7. The distance between the first glue knife 6 and the second glue knife 7 is 70-90 mm. The first glue knife 6 and the second glue knife 7 are movably installed on one side of the sizing surface of the cardboard and are perpendicular to the sizing surface of the cardboard. By controlling the distance between the cutting edge of the glue knife and the sizing surface of the cardboard, the contact force of the first glue knife 6 or the second glue knife 7 on the cardboard is regulated. Preferably, the first glue knife 6 and the second glue knife 7 are conical scraping knives. The glue knife 2 for the sizing roller is a square scraping knife and the rotation angle is 1-3 degrees.

[0018] When the pipe winding machine runs at a low speed, the angle between the glue knife 2 for the sizing roller and the sizing roller 1 is reduced to reduce the glue amount applied to the cardboard by the sizing roller 1, and then the glue amount applied to the cardboard is finely adjusted by adjusting the first glue knife 6 according to the forming condition of the paper core tube.

[0019] When there is an opening phenomenon in the lap joint bonding of the end face cut of the paper core tube, the contact force between the first glue knife 6 and the cardboard is adjusted to be reduced. If the glue amount is too large and the humidity of the paper core tube is high, the paper core tube is likely to bend and cause machine jamming during the rewinding process. Then, the contact force between the glue knife 2 for the sizing roller and the sizing roller is adjusted to reduce the angle, and then the contact forces between the first glue knife 6, the second glue knife 7 and the cardboard are finely adjusted according to whether there is an opening at the end face cut of the paper core tube.

[0020] The utility model controls the glue application amount of the glue applicator roll by adding a glue applicator roll knife in front of the glue applicator roll, which can adjust the angle between the glue applicator roll knife and the glue applicator roll. At the same time, double glue knives are added between the first paper guide roll and the second paper guide roll to better control the evenness of the glue amount on the sizing surface of the cardboard, improve the speed of the pipe winding machine, improve the qualified rate of the paper core tube, and reduce the production cost.
