[0002] Packaging machines are machines that package products, serving to protect and enhance their appearance. Packaging machines mainly fall into two categories: 1. Automated production line packaging; 2. External packaging equipment for products.

[0003] The existing patent with authorization announcement number CN221163643U discloses a film tension adjustment device suitable for packaging machines. The device uses two symmetrically arranged adjustment mechanisms to adjust the tension of the film by operating the rotating handle, and the scale value indicated by the pointer helps the user to make precise adjustments to the tension of the film.

[0004] However, the aforementioned device revealed certain problems during use. On the one hand, the device requires manual adjustment of the two adjustment mechanisms, which cannot guarantee synchronization and results in significant adjustment errors. On the other hand, users can only judge the tension adjustment by the scale readings, making precise adjustment difficult.

[0005] Based on this, a material tension adjustment mechanism for packaging machines is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] In one embodiment, such as Figure 1 and Figure 2 As shown, a packaging machine material tension adjustment mechanism includes a frame 100. Two side plates 101 are symmetrically arranged on the frame 100. A tension monitoring component 200 is provided on the side plate 101. A coarse adjustment component 300 is provided on one side of the tension monitoring component 200, and a fine adjustment component 400 is provided on the other side of the tension monitoring component 200. A connecting beam 102 is provided on the side of the frame 100 near the fine adjustment component 400. The fine adjustment component 400 is installed on the connecting beam 102. A guide frame 103 is provided below the connecting beam 102. Two vertical guide grooves 104 are symmetrically arranged on the side plate 101 and are located below the guide frame 103. In use, the tension of the packaging material is detected in real time by the tension monitoring component 200, and the tension of the packaging material is precisely adjusted by the coarse adjustment component 300 and the fine adjustment component 400.

[0026] In one embodiment, such as Figure 2 As shown, the tension monitoring component 200 includes a first rotating shaft 201 fixedly installed on the side plate 101, a first roller 202 rotatably mounted on the first rotating shaft 201, and two tension sensors 203 symmetrically arranged at both ends of the first rotating shaft 201. In use, the tension of the packaging material on the first roller 202 is detected in real time by the two tension sensors 203, and the numerical information is transmitted to the external control system. The control system controls the coarse adjustment component 300 and the fine adjustment component 400 to adjust the tension of the packaging material.

[0027] In one embodiment, such as Figure 2 As shown, the coarse adjustment assembly 300 includes two movable arms 301 symmetrically arranged inside the side plate 101. One end of each movable arm 301 is rotatably connected to the side plate 101, and the other end of each movable arm 301 is fixedly mounted with a second rotating shaft 302. A second roller 303 is rotatably mounted on the second rotating shaft 302. One end of the second rotating shaft 302 is provided with a driving component, which includes an electric push rod 304 disposed on the outside of the side plate 101. The fixed end of the electric push rod 304 is rotatably connected to the side plate 101, and the output end of the electric push rod 304 is rotatably connected to one end of the second rotating shaft 302. In use, by controlling the extension and retraction of the electric push rod 304, the second rotating shaft 302 is driven to rotate under the drive of the movable arms 301, thereby controlling the pressure of the second roller 303 on the packaging material and realizing the adjustment of the tension of the packaging material.

[0028] In one embodiment, such as Figure 3 As shown, the fine-tuning assembly 400 includes a movable seat 401 disposed below the guide frame 103. Two guide blocks 402 are symmetrically arranged on both sides of the movable seat 401. The guide blocks 402 are slidably installed within the vertical guide groove 104. A third rotating shaft 403 is fixedly installed at the lower end of the movable seat 401, and a third roller 404 is rotatably mounted on the third rotating shaft 403. An adjusting component is provided at the upper end of the movable seat 401. The adjusting component includes a sleeve 405 fixed to the upper end of the movable seat 401. The sleeve 405 is slidably connected to the guide frame 103, and a screw 406 is threaded into the sleeve 405. The screw 406 is driven by the motor 407, which is mounted on the connecting beam 102. The upper end of the sleeve 405 is provided with a telescopic protective sleeve 408, which is sleeved on the outside of the screw 406. The upper end of the telescopic protective sleeve 408 is fixedly connected to the connecting beam 102. In use, the screw 406 is driven to rotate by the motor 407, which causes the sleeve 405 to move up and down along the screw 406. At the same time, the movable seat 401 and the third roller 404 move up and down, thereby controlling the pressure of the third roller 404 on the packaging material and realizing a slight and precise compensation for the tension of the packaging material.

[0029] The above embodiment discloses a packaging machine material tension adjustment mechanism. In use, two tension sensors 203 detect the tension of the packaging material on the first roller 202 in real time and transmit the numerical information to an external control system. The control system controls the coarse adjustment component 300 and the fine adjustment component 400 to adjust the tension of the packaging material. First, coarse adjustment is performed by the coarse adjustment component 300, and then fine adjustment is performed by the fine adjustment component 400. During coarse adjustment, the extension and retraction of the electric push rod 304 is controlled, which drives the second rotating shaft 302 to rotate under the drive of the movable arm 301, thereby controlling the pressure of the second roller 303 on the packaging material and adjusting the tension of the packaging material. During fine adjustment, the screw 406 is driven to rotate by the motor 407, causing the sleeve 405 to move up and down along the screw 406, and at the same time driving the movable seat 401 and the third roller 404 to move up and down, thereby controlling the pressure of the third roller 404 on the packaging material and achieving micro-precise compensation of the tension of the packaging material.
