[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] like Figures 1 to 3 As shown, the utility model provides a winding machine for packaging bag production that is easy to replace, including a body 1; the left and right sides of the inner wall of the body 1 are movably connected with a transmission rod 2, the inner side of the transmission rod 2 is fixedly connected with a shift fork 3, the interior of the shift fork 3 is movably connected with a bag roller 4, the end of the transmission rod 2 close to the body 1 penetrates into the interior of the body 1 and is fixedly connected with a swing rod 5, the interior of the body 1 is movably connected with a screw rod 6 through a bearing, the surface of the screw rod 6 is threadedly connected with a screw sleeve 7, the outer side of the screw sleeve 7 is fixedly connected with a slide rod 8 located inside the swing rod 5, and the slide rod 8 is slidably connected to the swing rod 5.

[0020] refer to Figure 3 A stepper motor 9 is fixedly connected to the interior of the machine body 1, and the output end of the stepper motor 9 is fixedly connected to the left end of the screw rod 6. By setting the stepper motor 9, the two screw rods 6 can rotate synchronously, and the two screw rods 6 maintain the same speed.

[0021] refer to Figure 3 The surface of the swing rod 5 is fixedly connected with a spring plate 10, and the side of the spring plate 10 away from the swing rod 5 contacts the inner surface of the body 1, and the spring plate 10 is elastic. By providing the spring plate 10, the swing rod 5 can be supported and the influence of vibration on the swing rod 5 can be reduced.

[0022] refer to Figure 3 The body 1 is fixedly connected with a guide rod 11, and the screw sleeve 7 is sleeved on the surface of the guide rod 11 and is slidably connected with the guide rod 11. By setting the guide rod 11, the screw sleeve 7 can be limited to avoid the screw sleeve 7 from tilting during the movement.

[0023] refer to Figure 1 The bottom of the machine body 1 is fixedly connected with a buffer pad 12, which extends from the side away from the machine body 1 to the left side of the machine body 1. The buffer pad 12 is made of rubber. By providing the buffer pad 12, the impact force generated when the bag roller 4 falls can be reduced, and the bag roller 4 can be prevented from having a dry collision with the ground.

[0024] refer to Figure 1 The inner side of the bag roller 4 is fixedly connected with a linkage rod 13, and the linkage rod 13 has the same axis as the transmission rod 2. By arranging the linkage rod 13, the two shift forks 3 can be connected, which is convenient for power transmission.

[0025] When the utility model is in use, the bag roller 4 is supported by the fork 3 and the packaging bag is wound and rolled. When the bag roller 4 needs to be replaced, the stepper motor 9 is turned on, and the stepper motor 9 drives the screw rod 6 to rotate. The screw rod 6 uses the thread to push the screw sleeve 7 to move to the left side. During the movement of the screw sleeve 7, the slide bar 8 is driven to slide inside the swing rod 5. The swing rod 5 is squeezed and drives the fork 3 to swing through the transmission rod 2. When the swing rod 5 carries the fork 3 to move to the left side of the body 1, the bag roller 4 can roll and slide to the outside of the body 1 and separate from the body 1.

[0026] In summary, the easily replaceable winding machine for packaging bag production can improve the way the existing winding machine installs the bag roller 4, saves the operation steps of lifting with the help of a forklift, saves time and effort, and can prevent the bag roller 4 from falling during transportation.
