Description

Technical Field

[0001] The present invention relates to the field of printing equipment, and in particular to an intelligent label printing device. Background Art

[0002] In recent years, with the rapid development of e-commerce, logistics warehousing and retail industries, label printers, as core equipment for commodity identification management, have seen a continuous increase in market demand. Among them, small-scale intelligent label printing devices are favored in scenarios such as store shelf management, laboratory sample identification, and small warehouse management due to their small footprint and flexible deployment. However, while existing miniaturized intelligent label printing devices pursue compact structures, they generally have the following technical defects:

[0033] See also Figures 1 to 6 An embodiment of the intelligent label printing device of the present invention is shown, comprising: a transmission channel 1, a printing roller 2, a printing device 3 and a peeling plate 4. The transmission channel 1 is used to transmit labels, and movable baffles are provided on both sides of the transmission channel 1 to transmit labels of different specifications. The printing roller 2 is provided at the end of the transmission channel 1 and is configured to be rotatable, so as to drive the label to move and print on the printing roller 2.

[0034] The printing device 3 is arranged above the printing roller 2 and is configured to be able to be lifted / lowered, and the contact or separation between the print head and the surface of the printing roller 2 is achieved through the lifting and lowering movement. The peeling plate 4 is arranged in front of the printing roller 2, and the cross section of the peeling plate 4 is configured as a triangle with an acute angle at the front end, and the bottom side of the triangle is parallel to and closely attached to the upper surface of the object to be labeled, that is, the bottom surface of the peeling plate 4 is kept in a parallel and attached state with the upper surface of the object to be labeled, and uniform pressure is applied during the movement of the label tape.

[0035] The printing device 3 includes a mounting shaft 36, a first cantilever frame 32, a second cantilever frame 33 and a driving assembly 35. The mounting shaft 36 runs horizontally through the two side plates of the device body. The first cantilever frame 32 and the second cantilever frame 33 are arranged on the mounting shaft 36 in parallel, and an elastic connection structure is formed between the two by an elastic member, allowing relative displacement and generating a restoring force. A rotating shaft 34 is arranged above the first cantilever frame 32, and the rotating shaft 34 is driven and connected with a wrench, and the rotating shaft 34 is rotated by manually turning the wrench. In some other embodiments, the rotating shaft 34 is connected to the output end of the driving motor through a coupling. The driving assembly 35 is fixedly sleeved on the rotating shaft 34, and includes 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 installed 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. When the rotating shaft 34 rotates, the moving trajectory of the rotating wheel 351 of the driving assembly 35 along the surface of the first cantilever frame 32 changes.

[0036] A raised limit plate 321 is provided on the upper surface of the first cantilever frame 32, and the limit plate 321 is used to restrict the moving range of the rotating wheel 351. When the rotating wheel 351 contacts different positions of the limit plate 321, the first cantilever frame 32 is pushed to produce an angular deflection around the mounting shaft 36, and then the second cantilever frame 33 is driven to move synchronously through the elastic member. A print head assembly 31 is provided on the bottom side of the second cantilever frame 33, including a mounting plate 313, a heat sink 312 and a print head 311 connected in sequence, wherein the front end of the heat sink 312 extends downward to form a baffle structure, and the baffle has a guiding function to guide the label tape to move toward the stripping plate 4. Preferably, the print head 311 is fixed below the heat sink 312 through a quick release mechanism for easy maintenance and replacement. The second cantilever frame 33 is provided with a through slot, the mounting plate is provided with a mounting block 314 that penetrates the through slot, the front end of the second cantilever frame 33 is provided with a fixing plate 331 that extends upward perpendicularly to the second cantilever frame 33, and includes a first adjusting screw 332, the first adjusting screw 332 penetrates the fixing plate 331 and is threadedly connected to the mounting block 314, and the first adjusting screw 332 is adjusted to rotate to change the position of the mounting plate 313 relative to the through slot, thereby driving the print head assembly 31 to move and changing the position of the print head 311 relative to the printing roller. Specifically, the first adjusting screw 332 and the mounting block 314 are both provided in two groups, which are arranged relative to each other, which improves the stability performance while facilitating disassembly and assembly, and can be directly operated from the front side of the device, which is simple and convenient to operate.

[0037] Furthermore, a second adjusting screw 37 is vertically disposed on the second cantilever frame 33, and the second adjusting screw 37 passes through the mounting plate 313 and is detachably connected to the print head assembly 31. By providing the second adjusting screw 37, the print head assembly 31 can be quickly assembled and disassembled, thereby improving work efficiency.

[0038] The detection module is integrated in the middle of the transmission channel 1, including a fixed shaft 12, a sleeve 13 and an infrared sensor unit 11. The fixed shaft 12 is installed parallel to the transmission channel 1. The sleeve 13 is movably arranged on the fixed shaft 12, and a through slot 14 is provided in the center of the sleeve 13 as a label tape channel. Infrared transmitters and receivers are symmetrically arranged on both sides of the slot 14 to form a non-contact detection optical path. The position of the sleeve 13 can be adjusted on the fixed shaft 12 through a locking mechanism to meet the detection requirements of label tapes of different widths. The output signal of the infrared sensor 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 sensing unit of the detection module detects that the label tape passes through the through slot, an electrical signal is sent to the control unit, and the control unit immediately starts the driving motor to drive the rotating shaft 34 to rotate. The rotation angle of the rotating shaft 34 is precisely controlled, so that the rotating wheel 351 of the driving assembly 35 moves to a predetermined position along the surface of the first cantilever frame 32. In this process, the interaction between the rotating wheel 351 and the limiting plate 321 pushes the first cantilever frame 32 downward, and the force is transmitted to the second cantilever frame 33 through the elastic member, and finally the print head assembly 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 printed label tape is guided to the peeling plate 4 area through the blocking bar at the front end of the heat sink 312. The sharp angle structure at the front end of the peeling plate 4 causes the label tape to bend and deform, and the base paper changes its direction of travel at the sharp 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 operation process.

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

[0042] In some preferred embodiments, a frame is further included, and a mounting shaft 36 is arranged on the frame. An adjusting shaft 7 is also provided above the mounting shaft 36. Both ends of the adjusting shaft 7 are rotatably connected to the frame. One end of the mounting shaft 36 is connected to the frame, 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 is also provided on the frame for the mounting shaft 36 to pass through. The limiting groove 72 is arranged in a vertical direction. When the adjusting shaft 7 rotates, the mounting shaft 36 is driven to move in the direction of the vertical limiting groove 72, so as to achieve the effect of adjusting the height of the mounting shaft 36, thereby changing the position height of the print head assembly, which is suitable for the needs of different types of paper.

[0043] In some preferred embodiments, a waste paper tape recovery channel 5 is provided below the transmission channel 2, and a plurality of transmission rollers 45 for transmitting waste paper tape are provided in the waste paper tape recovery channel 5, and the transmission rollers 45 are configured as a quick-release structure. A first rubber roller 51 and a second rubber roller 52 are also provided in the waste paper tape recovery channel 5, which are arranged opposite to each other up and down, and a rotatable box cover 53 is provided below the second rubber roller 52, and a hook lock 54 is provided at one end of the box cover 53 for locking the box cover 53 in a closed state. Preferably, the printing roller, the first rubber roller 51 and the second rubber roller 52 are all configured as a quick-release structure.

[0044] The quick-release structure is a structure 6 with a conical or frustum-shaped end, such as Figure 4 As shown, a plane 61 parallel to the axis is provided, and correspondingly a bearing with a meshing structure can be arranged on the frame, thereby achieving the effect of quick disassembly and assembly.

[0045] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
