Description

Technical Field

[0001] This utility model relates to the field of packaging paper guiding technology, specifically a packaging paper guiding mechanism with tensioning function. Background Technology

[0002] Packaging paper is a general term for a type of paper used for packaging purposes. It can be divided into ordinary packaging paper, special packaging paper, trademark paper, oil-proof packaging paper, and moisture-proof packaging paper, etc.

[0003] During the printing process of packaging paper, both printing and subsequent drying generally require a guiding mechanism for guidance to facilitate subsequent processes. Currently, packaging paper guiding mechanisms typically employ a vertical lifting structure for height adjustment. However, during adjustment, the packaging paper is prone to loosening, thus necessitating the use of a tensioning mechanism. The existing tensioning and guiding mechanisms are two independent systems, leading to increased costs and larger space requirements. Therefore, an improved technology is urgently needed to address this problem in the current technology. Utility Model Content

An adjusting cylinder is connected to the outer side of the swing arm away from the fixed plate via a rotating shaft. The piston rod of the adjusting cylinder is rotatably connected to the support via a rotating shaft. The two swing arms are connected to the discharging guide roller at their ends away from the fixed plate. A feeding guide roller is mounted on the outer side of the swing arm via a bearing seat.

[0017] Please see Figure 1-2This utility model provides a technical solution: a packaging paper guiding mechanism with a tensioning function, including a fixed plate 1, a swing arm 2, an adjusting cylinder 3, a tensioning cylinder 4, a feeding guide roller 5, a discharging guide roller 6, and a tensioning roller 7. There are two fixed plates 1, each connected to a bracket 9 via a connecting plate 8. A second reinforcing rod 12 connects the two fixed plates 1 to ensure the structural strength and stability between them. The outer ends of each fixed plate 1 are rotatably connected to the swing arm 2 via a rotating shaft. Several first reinforcing rods 11 connect the two swing arms 2 to ensure synchronous movement of the two swing arms 2 and the structural stability of the entire guiding mechanism. The outer side of the swing arm 2 away from the fixed plate 1 is connected to an adjusting cylinder via a rotating shaft. 3. The adjusting cylinder 3 is provided with an ear plate 13. The adjusting cylinder 3 is rotatably connected to the swing arm 2 through the ear plate 13 and the rotating shaft to realize the connection between the adjusting cylinder 3 and the swing arm 2. The piston rod of the adjusting cylinder 3 is rotatably connected to the bracket 9 through the rotating shaft. The support 14 is provided on the outside of the bracket 9. The piston rod of the adjusting cylinder 3 is rotatably connected to the support 14 through the rotating shaft to ensure the connection between the piston rod of the adjusting cylinder 3 and the bracket 9. The two swing arms 2 are connected to the discharge guide roller 6 at the ends away from the fixed plate 1. The feed guide roller 5 is provided on the outside of the swing arm 2 through the bearing seat 10. The tensioning cylinder 4 is provided on the outer surface of the swing arm 2 between the discharge guide roller 6 and the feed guide roller 5. The piston rod of the tensioning cylinder 4 is connected to the tensioning roller 7.

[0018] Installation method and operating principle: First, install the first reinforcing rod 11 between the two swing arms 2 to make the two swing arms 2 rotate synchronously. At the same time, rotatably connect both ends of the discharge guide roller 6 to the outer ends of the two swing arms 2 respectively. Then, connect the adjusting cylinder 3 to the swing arm 2 through the ear plate 13 and the rotating shaft. Next, install both ends of the feeding guide roller 5 on the swing arm 2 through the bearing seat 10. Install the tensioning cylinder 4 on the outer surface of the swing arm 2, and connect both ends of the tensioning roller 7 to the piston rod of the tensioning cylinder 4 respectively. Finally, connect the fixing plate 1 to the bracket 9 through the connecting plate 8 and bolts. Rotately connect the piston rod of the adjusting cylinder 3 to the support 14 installed on the outer end of the bracket 9 through the rotating shaft to complete the installation. During operation, the packaging paper passes through the feeding guide roller 5, the tensioning roller 7 and the discharge roller in sequence. By adjusting the extension and retraction of the piston rod of the adjusting cylinder 3, the angle of the swing arm 2 is adjusted to control the height of the discharge guide roller 6, thereby determining the discharge height of the packaging paper. At the same time, the tensioning cylinder 4 drives the tensioning roller 7 to move back and forth to achieve tensioning of the paper. This utility model has a reasonable structure. By adjusting the angle of the adjusting arm 2 driven by the adjusting cylinder 3, the height of the discharge guide roller 6 can be controlled, thereby realizing the adjustment of the discharge height of the packaging paper, which greatly improves the flexibility. At the same time, through the cooperation of the tensioning cylinder 4 and the tensioning roller 7, tensioning can be performed during the process of guiding the height adjustment agent of the packaging paper, which greatly improves the convenience and eliminates the need for a separate tensioning mechanism, reducing costs and saving installation space.
