[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example 1

[0023] Reference Figure 1-4 A packaging paper feeding device for a filling machine includes a base 1, two supports 5, and four guide rollers 6. The two supports 5 are fixedly mounted on the top of the base 1, and the four guide rollers 6 are respectively fixedly mounted on the two supports 5. The winding device also includes...

The control mechanism includes the electric push rod 7 fixed on the top of the base 1, the frame 8 connected to the output end of the electric push rod 7, the tension roller 9 rotatably connected to the inner side of the frame 8 to provide adjustable tension, and the sliding frames 10 sliding to the outer side of the frame 8 to drive the correction rollers 11 to adjust their position, so as to realize flexible control of the tightness of the packaging paper and correction of deviation, ensuring constant and stable feeding tension, and adapting to packaging paper of different widths.

[0026] In order to adjust the correction roller 11, the fixing mechanism includes: a fixing rod 12, four support rods 13, two contact rods 14, two driving rods 16 and two rotating rods 17; The fixing rod 12 is fixedly installed on the top of the frame 8, and the four support rods 13 are respectively fixedly installed on the top of the two sliding frames 10.

The top of the rotating support rod 13 contacts the driving rod 16. The rotating rod 17, by squeezing the driving rod 16, causes the bonding rod 14 to disengage from the insertion slot on the fixed rod 12, thereby unlocking the position of the sliding frame 10. This allows for free adjustment of the current position of the sliding frame 10 and the alignment roller 11, making it easy to adapt to various packaging papers. The bonding rod 14, through the rebound of the spring 15, is inserted into the positioning slot on the fixed rod 12 to lock the position of the sliding frame 10, ensuring that the working position of the alignment roller 11 and the tension roller 9 is stable.

The top of the fixing rod 12 is provided with equally spaced insertion slots for the bottom of the fitting rod 14 to slide in contact. The fitting rod 14 can be reliably inserted into the selected insertion slot, providing multiple stable locking positions for the sliding frame 10, and adapting to the correction needs of packaging paper of different widths.

[0029] In order to install the fitting rod 14, a vertical groove is provided on the support rod 13. The fitting rod 14 is slidably connected to the inner wall of the vertical groove. The vertical groove on the support rod 13 allows the fitting rod 14 to slide, constraining the vertical movement path of the fitting rod 14 and ensuring that its engagement or disengagement with the fixed rod 12 is smooth and accurate.

[0030] To achieve the resetting of the fitting rod 14, four symmetrically arranged springs 15 are fixedly installed at the bottom of each of the two fitting rods 14. The four springs 15 are respectively fixedly installed on the top of the two sliding frames 10.

The springs 15 provide continuous pressure to keep the fitting rod 14 in reliable contact with the fixed rod 12, enhance the locking stability, and prevent loosening during operation from affecting the correction effect.

[0031] The working principle of this utility model is as follows: An unwinding mechanism, including a winding frame 2 and a fixed base 1, is used. A motor 3 drives an air shaft 4 to automatically unwind the packaging paper. A control mechanism and a fixed mechanism, working in conjunction with the base 1, precisely adjust the tightness of the packaging paper and can also limit movement.

This achieves flexible control of the packaging paper tightness and correction of deviation, ensuring a constant and stable feeding tension, adapting to packaging paper of different widths. When it is necessary to adjust the distance between the two correction rollers 11, it is only necessary to operate the fixed mechanism on the sliding frame 10. The fixed mechanism includes a fixing rod 12. The top of the fixed frame 8 is fixed, the top of the support rod 13 is fixed, the bonding rod 14 slides inside the support rod 13, the driving rod 16 connects to the bonding rod 14, and the rotating rod 17 rotates the top of the support rod 13 to contact the driving rod 16. The operation of the rotating rod 17 causes the bonding rod 14 to disengage from the insertion slot on the fixed rod 12 by squeezing the driving rod 16, thereby unlocking the position of the sliding frame 10. This allows for free adjustment of the current position of the sliding frame 10 and the correction roller 11, making it easy to adapt to various packaging papers. The bonding rod 14 is inserted into the positioning slot on the fixed rod 12 by the rebound of the spring 15, locking the position of the sliding frame 10 and ensuring that the working position of the correction roller 11 and the tension roller 9 is stable. The spring 15 provides auxiliary clamping force to enhance the reliability of the locking, ensuring a stable and uniform unwinding process, adapting to different filling speed requirements, and improving the feeding quality.
