[0027] Refer to the attached Figure 1 - attached Figure 6 , a labeling machine with a tension adjusting function provided by the present utility model, includes a base 1, a support platform 2 and a labeling frame 3 are fixedly arranged on the top of the base 1, a through groove 4 and an obstacle avoidance groove 5 are opened inside the labeling frame 3, a transmission shaft 7 and a label reel 8 are installed inside the labeling frame 3, two auxiliary shafts 9 are fixedly inserted inside the labeling frame 3, a label tape 10 is sleeved outside the transmission shaft 7 and the label reel 8, a labeling part conveyor belt 11 is arranged at the bottom of the label tape 10, and a tension adjusting mechanism is arranged inside the through groove 4;

[0028] The tension adjustment mechanism includes a knob 12. A worm 13 is fixedly provided on one side of the knob 12. The worm 13 passes through the obstacle avoidance groove 5 and is connected to the two side walls of the obstacle avoidance groove 5 through bearings. A worm gear 14 is provided at the bottom of the worm 13. The worm 13 meshes with the worm gear 14. A threaded rod 15 is fixedly inserted inside the worm gear 14. A fixed block 16 is provided at one end of the threaded rod 15. A threaded sleeve 17 is sleeved outside the threaded rod 15. A connecting block 18 is fixedly provided at one end of the threaded sleeve 17. Two guide rods 19 are inserted inside the connecting block 18. Springs 20 are sleeved outside both of the two guide rods 19. A movable block 21 is fixedly provided at one end of the two guide rods 19. A tension shaft 22 is fixedly provided on one side of the movable block 21;

[0029] In this embodiment, in order to achieve the purpose of adjusting the tightness of the label tape 10 during winding, when the label tape 10 has appropriate tightness, rotate the knob 12. The rotation of the knob 12 causes the threaded rod 15 to rotate through the cooperation of the worm 13 and the worm gear 14. The rotation of the threaded rod 15 causes the connecting block 18 to slide horizontally in the through groove 4 through the threaded cooperation with the threaded sleeve 17, thereby adjusting the elastic position range of the movable block 21, and thus controlling the tightness of the label tape 10, preventing the situation that the tightness adjustment does not meet the production requirements. Through the elastic pulling of the connecting block 18, the guide rods 19, the springs 20, the movable block 21, and the tension shaft 22, the purpose of automatically adjusting the tightness of the label tape 10 is achieved, so that the label tape 10 can stably convey the labels, and at the same time automatically wind up the waste tape, which is convenient for subsequent centralized removal;

[0030] Among them, in order to achieve the purpose of winding the label tape 10, the following technical solution is adopted by this device: A motor 6 is fixedly provided on one side of the labeling frame 3. The output end of the motor 6 is fixedly connected to one end of the transmission shaft 7. The transmission shaft 7 and the unwinding shaft 8 both pass through the labeling frame 3 and are connected to the labeling frame 3 through bearings. The two ends of the label tape 10 are respectively sleeved outside the transmission shaft 7 and the unwinding shaft 8 and are fixedly connected to the transmission shaft 7 and the unwinding shaft 8. The label tape 10 is sleeved outside the two auxiliary shafts 9 and the tension shaft 22. The label tape 10 is respectively slidably connected to the two auxiliary shafts 9 and the tension shaft 22. When it is necessary to wind up the label tape 10, start the motor 6 to rotate. The rotation of the motor 6 drives the transmission shaft 7 to rotate. The rotation of the transmission shaft 7 winds up the label tape 10, winds up the waste tape of the label tape 10, and at the same time unwinds the area with labels, so as to facilitate the labeling device to stick the labels on the products conveyed by the labeling part conveyor belt 11, achieving the purpose of labeling. During the winding process of the label tape 10, to prevent the label tape 10 from being slack or taut, through the elastic pulling of the connecting block 18, the guide rods 19, the springs 20, the movable block 21, and the tension shaft 22, the purpose of automatically adjusting the tightness of the label tape 10 is achieved, so that the label tape 10 can stably convey the labels, and at the same time automatically wind up the waste tape;

[0031] Among them, in order to achieve the purpose of adjusting the tightness of the label tape 10 and preventing excessive stretching of the elastic force of the label tape 10, the following technical solution is adopted by this device: One end of the threaded rod 15 is connected to the fixed block 16 through a bearing. The fixed block 16 is fixedly arranged inside the through groove 4. The other end of the threaded rod 15 extends into the inside of the threaded sleeve 17 and is threadedly connected to the threaded sleeve 17. Both the connecting block 18 and the movable block 21 are arranged inside the through groove 4 and are slidably connected to the through groove 4. The guide rod 19 penetrates through the connecting block 18 and is slidably connected to the connecting block 18. One end of the spring 20 is fixedly connected to the connecting block 18, and the other end of the spring 20 is fixedly connected to the movable block 21. Rotate the knob 12. The rotation of the knob 12 causes the threaded rod 15 to rotate through the cooperation of the worm 13 and the worm gear 14. The rotation of the threaded rod 15 causes the connecting block 18 to slide horizontally in the through groove 4 through the threaded cooperation with the threaded sleeve 17, thereby adjusting the elastic position range of the movable block 21, and thus controlling the tightness of the label tape 10 to prevent the situation that the tightness adjustment does not meet the production requirements.

[0032] The use process of this utility model is as follows: When using this utility model and it is necessary to wind up the label tape 10, start the motor 6 to rotate. The rotation of the motor 6 drives the transmission shaft 7 to rotate. The rotation of the transmission shaft 7 winds up the label tape 10 and winds up the waste tape of the label tape 10. At the same time, the area with labels is unwound, so as to facilitate the labeling device to stick the label on the product conveyed by the labeling part conveyor belt 11 to achieve the purpose of labeling. During the winding process of the label tape 10, prevent the label tape 10 from being loose or taut. Through the elastic pulling cooperation of the connecting block 18, the guide rod 19, the spring 20, the movable block 21, and the tension shaft 22, the purpose of automatically adjusting the tightness of the label tape 10 is achieved, so that the label tape 10 can stably convey the label and automatically wind up the waste tape at the same time, which is convenient for subsequent centralized removal. When the label tape 10 is to have appropriate tightness, rotate the knob 12. The rotation of the knob 12 causes the threaded rod 15 to rotate through the cooperation of the worm 13 and the worm gear 14. The rotation of the threaded rod 15 causes the connecting block 18 to slide horizontally in the through groove 4 through the threaded cooperation with the threaded sleeve 17, thereby adjusting the elastic position range of the movable block 21, and thus controlling the tightness of the label tape 10 to prevent the situation that the tightness adjustment does not meet the production requirements.
