The surfaces of the two mounting heads 4 are both engaged with mounting blocks 5, and the two mounting blocks 5 are respectively fixedly connected to the two ends of the winding shaft 6. External threads 7 are provided on both sides of the surface of the winding shaft 6. The surface of the external threads 7 is threadedly sleeved with a limit plate 8 to prevent the label paper roll 9 from deviating. The middle part of the winding shaft 6 is wound with a label paper roll 9 to be sent for printing. A tape inlet 22 is provided at the bottom of the front side of the label printing machine body 1.

A buzzer 24 is fixedly installed on one side of the top of the label printing machine body 1 to serve as a reminder. A reduction motor 3 is fixedly installed on the top of the side wall of the front frame 2.

[0027] When in use, by threading the limit disk 8 on both sides of the surface of the winding shaft 6 of the unwinding mechanism, the limit disk 8 can be turned to rotate and adjust its position on the winding shaft 6, so that the label paper rolls 9 of different widths can be limited and prevented from deflecting. By setting a photoelectric switch 23 at the tape inlet 22 of the label printing machine body 1, when the label paper roll 9 is used up or broken during the operation of the machine, the photoelectric switch 23 will control the buzzer 24 to alarm, so as to promptly remind the staff to carry out maintenance.

[0028] A accommodating chamber 10 is provided inside the mounting head 4, and grooves 12 are provided at both ends of one side of the inner wall of the accommodating chamber 10. The inner walls of the two grooves 12 are fixedly connected with springs 13, and one end of the two springs 13 is fixedly connected with a movable plate 14. Two plug rods 16 are fixedly connected to the surface of the movable plate 14. Two slots 17 are provided inside the mounting block 5, and one end of the plug rod 16 is engaged with the inner wall of the slot 17 to play a locking role. An electromagnet 11 is fixedly embedded in the middle of one side of the inner wall of the accommodating chamber 10, and an iron sheet 15 is fixedly embedded in the middle of the movable plate 14.
