[0019] In order to make the purpose, features, and advantages of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the embodiments described below are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0020] Reference Figure 1 , Figure 2 and Figure 3 , a height-adjustable paper box automatic labeling machine comprises a labeling machine body 1 and a labeling machine chassis 2, a plurality of sliding holes which cooperate with the limit slide bar 6 and the output end of the servo motor 5 are equidistantly opened on the top of the labeling machine chassis 2, a height of the support frame 4 is less than the height of the labeling machine chassis 2, a conveyor belt 3 is arranged on the top surface of the labeling machine chassis 2 on the side of the labeling machine body 1, and a support frame 4 is fixed on the bottom surface of the labeling machine chassis 2 below the conveyor belt 3, a plurality of servo motors 5 are equidistantly arranged on the top of the support frame 4, and the output ends of the servo motors 5 all slide through the top of the labeling machine chassis 2 and are fixed to the bottom surface of the conveyor belt 3, a plurality of limit slide bars 6 are equidistantly fixed to the bottom surface of the conveyor belt 3 on both sides of the servo motor 5, each limit slide bar 6 is arranged in an inverted "T" shape, the height of each limit slide bar 6 is greater than the height of the output end of the servo motor 5, and the limit slide bars 6 are all slidably inserted in the inside of the labeling machine chassis 2, and a guide component is arranged on the top of the conveyor belt 3.

[0021] Specifically, when the labeling height needs to be adjusted, the servo motor 5 is turned on so that the servo motor 5 runs to push the conveyor belt 3 to move, and the distance between the bottom of the carton on the conveyor belt 3 and the labeling machine body 1 can be adjusted to adjust the labeling height. When the conveyor belt 3 moves, it drives the limit slide bar 6 to slide inside the labeling machine frame 2 to ensure the stability of the conveyor belt 3 when moving.

[0022] As an optimization solution, Figure 3 As shown, the guide assembly includes a guide plate 7, a fixed plate 8, an adjusting screw 10 and an auxiliary sliding rod 12. The guide plate 7 is slidably arranged on the top surface of the conveyor belt 3. The end of the guide plate 7 away from the labeling machine body 1 is arranged in an arc shape inclined toward the side away from the labeling machine body 1. The end of the adjusting screw 10 extending to the outside of the conveyor belt 3 is fixed with a crank 11. The top surface of the conveyor belt 3 away from the labeling machine body 1 is fixed with a fixed plate 8, and a threaded sleeve 9 is embedded and fixed inside the fixed plate 8, and the adjusting screw 10 is threadedly sleeved inside the threaded sleeve 9. An auxiliary sliding rod 12 of the same length as the adjusting screw 10 is slidably inserted inside the fixed plate 8 below the adjusting screw 10, and the end of the auxiliary sliding rod 12 extending above the conveyor belt 3 is fixed to the side of the guide plate 7, and the end of the adjusting screw 10 extending above the conveyor belt 3 is rotatably connected to the guide plate 7 through a bearing.

[0023] Specifically, when labeling, the distance between the guide plate 7 and the labeling machine body 1 is adjusted according to the width of the carton. When adjusting, the crank 11 is turned to drive the adjusting screw 10 to rotate. When the adjusting screw 10 rotates, the guide plate 7 is driven to move with the cooperation of the thread, so as to adjust the width between the guide plate 7 and the labeling machine body 1, so that cartons of different widths can be guided to ensure the accuracy of labeling.
