Technical Field

[0001] This utility model relates to the field of labeling machine bottom paper winding technology, specifically a labeling machine bottom paper winding device. Background Technology

[0002] With the continuous improvement of industrial automation, every link in the production line is pursuing higher efficiency and lower costs. In the field of packaging machinery, the printing and labeling machine is one of the important pieces of equipment, and its performance improvement has a significant impact on the efficiency of the entire production line. As an important component of the printing and labeling machine, the efficiency and stability of the bottom paper recycling directly affect the overall operating effect of the equipment.

[0003] The existing label printing machine bottom paper recycling system has the following main problems: First, the label is not completely peeled off, which makes it impossible for the labeling machine to perfectly attach the label; second, the bottom paper is prone to breakage or jamming during the recycling process, which affects the normal operation of the equipment. The existing solution is to use multi-stage gear reduction to make the motor drive the roller to rotate to achieve bottom paper recycling. The structure is complex and costly, and it is impossible to manually adjust the bottom paper tension. Utility Model Content

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example: Figure 1-3As shown, this utility model provides a bottom paper winding device for a labeling machine, including a recycling roll 2. A bearing seat 31 is fixedly installed on one side of the inside of the recycling roll 2. A spring 32 is fixedly installed on one side of the bearing seat 31. A friction pad 34 is fixedly installed on the end of the spring 32 away from the bearing seat 31. The two sides of the friction pad 34 are slidably locked inside the recycling roll 2. A recycling roll base plate 13 is provided on one side of the recycling roll 2. A drive shaft 33 is fixedly installed in the middle of the recycling roll base plate 13. The drive shaft 33 passes through the middle of the recycling roll base plate 13 and the friction pad 34. By setting the recycling roll base plate 13 and the friction pad 34, the contact surface between the recycling roll base plate 13 and the friction pad 34 is specially treated to increase the friction between them, so that the motor 1 can easily drive the recycling roll 2 to rotate and enhance the surface hardness, which can extend the product life. A drive component is provided at one end of the drive shaft 33, and the other end of the drive shaft 33 is located in the middle of the bearing seat 31.

[0017] The bearing housing 31 has an internal zipper structure 311 on one side in the middle. A rotating tensioning structure 3 is installed in the middle of the internal zipper structure 311. One end of the rotating tensioning structure 3 is threaded onto the middle of one side of the drive shaft 33. A mounting plate 12 is provided on one side of the drive shaft 33.

[0018] The drive assembly includes a motor 1. One side of the motor 1 is fixedly mounted on the middle of one side of the mounting plate 12. The drive end of the motor 1 passes through the mounting plate 12. The end of the transmission shaft 33 away from the rotation tensioning structure 3 is fixedly mounted on the drive end of the motor 1. A control circuit board 11 is mounted on the side of the mounting plate 12 close to the motor 1. The control circuit board 11 works in conjunction with the motor 1. By setting the motor 1 and controlling the motor 1 through the control circuit board 11, the motor 1 drives the transmission shaft 33 to rotate, which in turn drives the recycling roll base plate 13 to rotate, which in turn drives the friction pad 34 to rotate. In other words, the friction pad 34 drives the recycling roll 2, which in turn drives the recycling roll 2 to rotate, thus achieving the recycling of the bottom paper.

[0019] The outer surface of the recycling roll 2 is provided with multiple sets of ring-shaped array springs 21. By setting the springs 21, the paper drum sleeved on the outer surface of the recycling roll 2 is limited, which facilitates the installation of the paper drum.

[0020] Working principle: In actual use, the paper drum is first loaded onto the recycling roll 2, and the bottom paper is pasted onto the paper drum. The control circuit board 11 controls the motor 1, which drives the transmission shaft 33 to rotate, that is, drives the recycling roll bottom plate 13 to rotate, which in turn drives the friction pad 34 to rotate. In other words, the friction pad 34 drives the recycling roll 2, which in turn drives the recycling roll 2 to rotate and achieve the recycling of the bottom paper.

[0021] Rotating the tensioning structure 3 clockwise can separate the friction pad 34 from the bottom plate 13 of the take-up reel, reducing friction and allowing manual adjustment of the bottom paper tension. Rotating the tensioning structure 3 counterclockwise can increase the pressure between the bottom plate 13 of the take-up reel and the friction pad 34, thereby increasing friction and increasing the rotation speed of the take-up reel 2, thus adjusting the tension of the bottom paper.

[0022] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
