[0033] Referring to Figures 1 to 6 An embodiment of the intelligent labeling printing device of the present application is shown, which comprises a transmission channel 1, an impression roller 2, a printing device 3 and a stripping plate 4. The transmission channel 1 is used to transmit the label, and movable baffles are provided on both sides of the transmission channel 1 to transmit labels of different specifications. The impression roller 2 is provided at the end of the transmission channel 1 and is configured to be rotatable to drive the label to move and print on the impression roller 2.

[0034] The printing device 3 is provided above the impression roller 2 and is configured to be liftable / liftable, and the contact or separation of the printing head and the surface of the impression roller 2 is realized by the lifting movement. The stripping plate 4 is provided in front of the impression roller 2, and the cross section of the stripping plate 4 is configured as a triangle with an acute angle at the front end, and the base of the triangle is parallel and close to the upper surface of the object to be labeled, that is, the bottom surface of the stripping plate 4 is kept in parallel and close state with the upper surface of the object to be labeled, and uniform pressure is applied during the label strip advancing.

[0035] The printing device 3 comprises a mounting shaft 36, a first cantilever frame 32, a second cantilever frame 33 and a driving assembly 35, and the mounting shaft 36 transversely penetrates through the two side plates of the equipment body. The first cantilever frame 32 and the second cantilever frame 33 are parallelly sleeved on the mounting shaft 36, and an elastic connection structure is formed between the two through an elastic member, allowing relative displacement and generating a restoring force. A rotating shaft 34 is provided above the first cantilever frame 32, and a wrench is drivingly connected to the rotating shaft 34, and the rotating shaft 34 is rotated by manually rotating the wrench. In some other embodiments, the rotating shaft 34 is connected to the output end of the driving motor through a shaft coupling. The driving assembly 35 is fixedly sleeved on the rotating shaft 34 and comprises a bracket 352 and a rotating wheel 351. The bracket 352 extends radially along the rotating shaft 34, and a freely rotatable rotating wheel 351 is mounted at the end. The bottom surface of the rotating wheel 351 forms a rolling contact with the upper surface of the first cantilever frame 32, and when the rotating shaft 34 rotates, the moving track of the rotating wheel 351 of the driving assembly 35 along the surface of the first cantilever frame 32 changes.

[0036] The upper surface of the first cantilever frame 32 is provided with a raised limiting plate 321 for restricting the movement range of the rotating wheel 351. When the rotating wheel 351 contacts different positions of the limiting plate 321, the first cantilever frame 32 is pushed to produce angular deflection around the mounting shaft 36, and then the second cantilever frame 33 is driven to move synchronously through the elastic member. The second cantilever frame 33 is provided with a print head assembly 31 at the bottom side, including a mounting plate 313, a heat sink 312 and a print head 311 connected in sequence, wherein the heat sink 312 extends downward at the front end to form a baffle structure, and the baffle has a guiding function of guiding the label tape to move in the direction of the stripping plate 4. Preferably, the print head 311 is fixed below the heat sink 312 through a quick release mechanism, which is convenient for maintenance and replacement. The second cantilever frame 33 is provided with a through groove, the mounting plate is provided with a mounting block 314 penetrating through the through groove, the front end of the second cantilever frame 33 is provided with a fixed plate 331 extending upward perpendicular to the second cantilever frame 33, and the fixed plate 331 includes a first adjusting screw 332 penetrating the fixed plate 331 and threadedly connected with the mounting block 314. By adjusting the rotation of the first adjusting screw 332, the position of the mounting plate 313 relative to the through groove is changed, and then the print head assembly 31 is driven to move, and the position of the print head 311 relative to the printing roller is changed. Specifically, the first adjusting screw 332 and the mounting block 314 are both provided in two groups in opposite positions, which improves the stability and facilitates disassembly and assembly, and can be directly operated from the front side of the equipment, which is simple and convenient to operate.

[0037] Further, the second cantilever frame 33 is also vertically provided with a second adjusting screw 37 penetrating the mounting plate 313 and detachably connected with the print head assembly 31. By providing the second adjusting screw 37, the print head assembly 31 can be quickly disassembled and assembled, improving the work efficiency.

[0038] The detection module is integrated in the middle of the transmission channel 1 and includes a fixed shaft 12, a sliding sleeve 13 and an infrared sensing unit 11. The fixed shaft 12 is installed parallel to the transmission channel 1. The sliding sleeve 13 is movably arranged on the fixed shaft 12, and a through groove 14 is formed in the center of the sliding sleeve 13 as a label tape channel. The infrared emitter and receiver are symmetrically arranged on both sides of the through groove 14 to form a non-contact detection light path. The position of the sliding sleeve 13 can be adjusted on the fixed shaft 12 through the locking mechanism to adapt to the detection requirements of label tapes with different widths. The output signal of the infrared sensing unit is connected to the control unit to trigger the subsequent action process.

[0039] In some other embodiments, the rotating shaft 34 is connected to a driving motor. When the infrared sensor unit of the detection module detects that the label tape passes through the through slot, an electrical signal is sent to the control unit, which then starts the driving motor to drive the rotating shaft 34 to rotate. The rotating angle of the rotating shaft 34 is precisely controlled, so that the rotating wheel 351 of the driving assembly 35 moves along the surface of the first cantilever frame 32 to a predetermined position. In this process, the interaction between the rotating wheel 351 and the limiting plate 321 pushes the first cantilever frame 32 to press downward, and the elastic member transmits the force to the second cantilever frame 33, so that the printing head assembly finally forms a working contact pressure with the surface of the printing roller 2.

[0040] The printing roller 2 keeps rotating at a constant speed during the printing process, driving the label tape to move along the transmission channel 1. The label tape that has completed printing is guided to the area of the peeling plate 4 by the blocking strip at the front end of the heat dissipation plate 312. The acute angle structure at the front end of the peeling plate 4 causes the label tape to be bent and deformed, and the base paper changes its moving direction at the acute angle, while the printed surface is flatly attached to the surface of the object to be labeled under the pressure of the bottom surface of the peeling plate 4. At this time, the base paper is separated from the label and continues to be recycled along the preset path, completing the entire labeling process.

[0041] The elastic coefficient of the elastic member is optimized and designed to provide adaptive pressure compensation when the printing head is pressed down, ensuring that label tapes of different thicknesses can all obtain uniform printing pressure. The heat dissipation plate 312 effectively controls the working temperature of the printing head.

[0042] In some preferred embodiments, a rack is further included, and the mounting shaft 36 is arranged on the rack. An adjusting shaft 7 is further arranged above the mounting shaft 36, both ends of the adjusting shaft 7 are rotatably connected to the rack, one end of the mounting shaft 36 is connected to the rack, and the other end is configured to be connected to the adjusting shaft 7 through a connecting rod 71. The adjusting shaft 7 is eccentrically connected to the connecting rod 71. A limiting groove 72 for the mounting shaft 36 to pass through is further arranged on the rack, and the limiting groove 72 is arranged in a vertical direction. When the adjusting shaft 7 rotates, it drives the mounting shaft 36 to move along the vertical direction of the limiting groove 72, so as to adjust the height of the mounting shaft 36, and then change the position height of the printing head assembly, which is suitable for the needs of different types of paper.

[0043] In some preferred embodiments, a waste paper tape recycling channel 5 is arranged below the transmission channel 2, a plurality of transmission rollers 45 for transmitting waste paper tape are arranged in the waste paper tape recycling channel 5, and the transmission rollers 45 are configured as quick-release structures. A first rubber roller 51 and a second rubber roller 52 arranged in an upper-lower opposite manner are further arranged in the waste paper tape recycling channel 5. A box cover 53 rotatably opened is further arranged below the second rubber roller 52, and a hook lock part 54 for locking the closed state of the box cover 53 is further arranged at one end of the box cover 53. Preferably, the printing roller, the first rubber roller 51 and the second rubber roller 52 are all configured as quick-release structures.

[0044] The quick release structure is a structure 6 with one end being a taper or frustum, as shown in the figure, and provided with a plane 61 parallel to the axis. Correspondingly, a bearing with an engaging structure can be arranged on the frame to achieve the effect of quick release and assembly. Figure 4

[0045] The above is only the preferred embodiment of the present application.
