DETAILED DESCRIPTION

[0021] In order to deepen the understanding of the present application, the present application will be further described in conjunction with the embodiments and the drawings, the embodiments are only used to explain the present application, and do not constitute the limitation of the protection scope of the present application.

[0022] A general-purpose outer box automatic labeling special machine, comprising a feeding mechanism 1, a first labeling mechanism 2, a reversing mechanism 3, a second labeling mechanism 4 and a control system 5. Among them, the feeding mechanism 1 is used to convey the outer box, and convey the outer box to the labeling station in turn;The first labeling mechanism 2 labels the first direction surface of the outer box, and conveys the labeled outer box to the reversing mechanism 3;The reversing mechanism 3 is used to change the conveying direction of the outer box to realize multi-direction labeling, which comprises an outer frame 31, an outer roller group 32, an inner frame 33, a small belt line group 34, a motor 35, a rotating wheel 36 and a sensor;The second labeling mechanism 4 is used to label the second direction surface of the reversed outer box, and convey the labeled outer box to the next process;The control system 5 is used to control the work of the feeding mechanism 1, the first labeling mechanism 2, the reversing mechanism 3 and the second labeling mechanism 4, and realize automatic multi-direction labeling.

[0023] The device transports the outer box to the labeling station through the feeding mechanism 1, the first labeling mechanism 2 labels the first direction surface of the outer box, and then sends it to the reversing mechanism 3. The reversing mechanism 3 supports the outer box by using the outer roller group 32, and when reversing is needed, the inner frame 33 is lifted by rotating the rotating wheel 36 driven by the motor 35, so that the small belt line group 34 contacts the outer box and changes its direction. After adjustment, the outer box enters the second labeling mechanism 4 to label the surface of the other direction, and finally enters the next process. The whole process is coordinated by the control system 5 to realize automatic labeling.

[0024] The feeding mechanism 1 includes a workbench 11, a first belt mechanism 12, a width adjustment mechanism 13, and a gear device 14. The first belt mechanism 12 is used to transport the outer box, the width adjustment mechanism 13 is used to adjust the distance between the first belt mechanism 12 to adapt to different sizes of the outer box, and the gear device 14 is used to control the single outer box entering the labeling station. After the outer box is placed on the workbench 11, it is transported to the labeling station by the first belt mechanism 12. The width adjustment mechanism 13 adjusts the distance between the first belt mechanism 12 to adapt to different specifications of the outer box. The gear device 14 ensures that only one outer box enters the labeling station at a time, avoiding overlapping or misplacement of the outer box.

[0025] The first labeling mechanism 2 includes a labeling machine 21 and a second belt mechanism 22. The labeling machine 21 is installed above the second belt mechanism 22 and can be adjusted in position to adapt to different labeling needs. The second belt mechanism 22 is used to transport the labeled outer box to the reversing mechanism 3. After the outer box is transported to the first labeling mechanism 2 by the feeding mechanism 1, the second belt mechanism 22 stably transports the outer box to the lower part of the labeling machine 21. The labeling machine 21 labels according to the preset position, and the height and angle can be adjusted to adapt to different sizes and specifications of the outer box. After labeling is completed, the second belt mechanism 22 continues to transport the outer box to the reversing mechanism 3.

[0026] It should be noted that the first labeling mechanism and the labeling mechanism have the same structure.

[0027] The outer roller group 32 is composed of a plurality of freely rolling rollers, and its axial direction is parallel to the outer box conveying direction, so as to reduce the friction force in the outer box reversing process and improve the reversing efficiency. The outer roller group 32 is installed on the outer frame 31 of the reversing mechanism 3, and the rollers are arranged in parallel along the conveying direction of the outer box, so that the outer box can slide smoothly. When the reversing mechanism 3 starts the lifting operation, the outer roller group 32 provides stable support while reducing friction, improving the smoothness of the outer box reversing.

[0028] The inner frame 33 is connected to the outer frame 31 through guide rails, so that it can be lifted stably without lateral shaking. The inner frame 33 can move vertically along the guide rails inside the outer frame 31. The guide rails provide precise guidance to ensure that the inner frame 33 remains stable during lifting and does not sway left or right, thereby ensuring the stability of the outer box during reversing.

[0029] The small belt line group 34 is composed of multiple synchronous belts and is driven by independent motors to ensure that the outer box can move stably to the second labeling mechanism 4 after reversing. The small belt line group 34 is installed on the inner frame 33 and is driven by independent motors. Its running direction is perpendicular to the conveying direction of the outer roller group 32. When the reversing mechanism 3 starts reversing, the belt line group 34 rises and contacts the bottom of the outer box to drive it to move, achieving the direction adjustment of the outer box.

[0030] The motor 35 is a servo motor that provides precise power output and is controlled by a drive control module to ensure accurate operation of the reversing mechanism 3. The servo motor 35 is installed on the outer frame 31 of the reversing mechanism 3 and is connected to the drive control module. After receiving the sensor signals, the control system 5 drives the servo motor 35 to operate to accurately control the lifting of the inner frame 33, so that the reversing mechanism 3 maintains a high-precision motion trajectory.

[0031] The worm gear transmission structure is adopted for the rotating wheel 36, and its output shaft is connected to the inner frame 33 to improve the lifting stability of the reversing mechanism 3 and reduce energy consumption. The motor 35 drives the worm gear mechanism, the worm rotates to drive the worm gear to rotate, and the output shaft of the worm gear is connected to the inner frame 33 to drive it to lift. Since the worm gear structure has a self-locking function, it will not slide during lifting, ensuring the stability of the reversing operation.

[0032] The sensors of the reversing mechanism 3 include photoelectric sensors and pressure sensors. The photoelectric sensors are used to detect whether the outer box is in place, and the pressure sensors are used to judge the stress on the reversing mechanism 3 to ensure the stability of the reversing process. The photoelectric sensors detect whether the outer box is in place and send signals to the control system 5 to trigger the reversing operation. The pressure sensors monitor the pressure on the outer box in real time during the reversing process to ensure stable reversing and prevent damage to the outer box due to excessive stress.

[0033] The control system 5 includes a PLC controller and is connected to a human-machine interface (HMI) to provide real-time monitoring, parameter adjustment, and fault alarm functions. The PLC controller receives signals from various sensors to control the operation of various mechanisms. The HMI provides an operation interface, allowing operators to monitor the equipment status in real time, adjust parameters, and provide alarm prompts when the equipment fails.

[0034] The above merely describes preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
