[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0020] Referring to Figures 1-4 , a printing device for packaging bags, including a workbench 1. Two side plates 2 are fixedly connected to the upper end of the workbench 1. A device rod 3 is jointly arranged between the two side plates 2. A first guide wheel 5 and a second guide wheel 6 are sleeved on the side wall of the device rod 3. Moving members 4 are arranged on the side walls of the first guide wheel 5 and the second guide wheel 6. Both of the two moving members 4 are concave on the side. The two moving members 4 are respectively connected to the first guide wheel 5 and the second guide wheel 6 through connecting devices. The connecting device includes a connecting rod 7 fixedly connected to the side wall of the moving member 4. The other end of the connecting rod 7 is fixedly connected with an anti-disengagement plate 10. A sliding groove 9 is penetrated through the side wall of the first guide wheel 5 or the second guide wheel 6 at the corresponding position. The anti-disengagement plate 10 is slidably connected in the sliding groove 9. The width of the inner part of the sliding groove 9 is greater than the width of the notch of the sliding groove 9, and the anti-disengagement plate 10 will not disengage from the corresponding sliding groove 9.

[0021] Among them, positioning devices are fixedly connected to the inner walls of the two moving members 4. The positioning device includes a positioning plate 11 fixedly connected to the inner wall of the moving member 4. An arc-shaped groove is penetrated through the lower end of the positioning plate 11. The lower end of the positioning plate 11 abuts against the side wall of the device rod 3.

[0022] Specifically, fixing devices are penetrated and threadedly connected to the side walls of the two moving members 4. The fixing device includes a connecting screw 8 penetrated through the side wall of the moving member 4. The tail end of the connecting screw 8 is located inside the moving member 4 and is rotatably connected with an arc-shaped plate 12. The arc-shaped plate 12 abuts against the side wall of the device rod 3.

[0023] In the present invention, when moving the first guide wheel 5 and the second guide wheel 6 to change their positions, when they need to be used together, the two moving members 4 on both sides can be directly toggled to drive the corresponding components to move. The positioning plates 11 arranged in the corresponding moving members 4 can play a role in positioning and reducing friction. After determining the position, the corresponding connecting screw 8 can be rotated to drive the corresponding arc-shaped plate 12 to move and abut against the side wall of the device rod 3, so as to fix the positions of the corresponding first guide wheel 5 and the second guide wheel 6. When the first guide wheel 5 and the second guide wheel 6 rotate on the device rod 3, the corresponding anti-disengagement plates 10 will slide in the corresponding sliding grooves 9, and will not affect the movement of the guide wheels.
