Description

Technical Field

[0001] This application relates to the field of printing equipment technology, and specifically to a label printer. Background Technology

[0002] Label printers are widely used in logistics, warehousing, retail and other industries to print and peel off labels for application.

[0003] Current label printing scenarios require peeling the printed label from the backing paper for individual use, while the remaining backing paper needs to be recycled. However, most existing label printers cannot achieve single-sided peeling and rewinding, meaning they cannot automatically separate the label from the backing paper and neatly recycle the backing paper during printing. This usually requires manual peeling or additional external equipment, resulting in cumbersome operation, low efficiency, and the random disposal of backing paper, which can easily lead to a messy working environment.

[0031] This application proposes improvements and innovations, and presents the following embodiments.

[0032] In some implementations, please refer to Figures 1 to 9 A label printer is provided, comprising: The housing 1 has a mounting plate 11 fixedly installed inside it; the mounting plate 11 divides the housing 1 into a first region 12 and a second region 13. Printing component 3 is fixedly connected to mounting plate 11 and is located within the first region 12; The tape loading roller 4 is rotatably connected to the mounting plate 11 and is located within the first region 12. The take-up roller 5 is rotatably connected to the mounting plate 11 and is located in the first area 12; the label paper 7 on the loading roller 4 passes through the printing assembly 3 and is fixedly connected to the take-up roller 5. The first motor 6 is fixedly connected to the mounting plate 11 and is located in the second area 13; the output end of the first motor 6 is connected to the loading roller 4 and the take-up roller 5 for transmission.

[0033] The first motor 6 simultaneously drives the loading roller 4 and the take-up roller 5, which, in conjunction with the operation of the printing component 3, can automatically peel the label off the backing paper during the printing process. The take-up roller 5 then synchronously recycles the peeled backing paper, achieving a single-sided peeling and rewinding integrated operation without manual intervention or external auxiliary equipment, significantly improving the degree of automation and ease of use.

[0034] The motor and paper tape transport area are separated, which effectively prevents paper scraps or dust generated by the paper tape from entering the motor, and at the same time avoids the heat of the motor from being conducted to the printing component 3, ensuring print quality and motor life.

[0035] Mounting plate 11 serves as a common mounting base, facilitating the integration of various components, reducing the overall size of the machine, and improving space utilization.

[0036] The first motor 6 simultaneously drives the loading roller 4 and the take-up roller 5, simplifying the transmission structure, reducing manufacturing costs, and ensuring smooth transmission.

[0037] The motor's independent area facilitates inspection and replacement, eliminating the need to disassemble the paper tape channel and improving maintenance efficiency.

[0038] The label paper 7 is wound into a disc shape, and the center of the disc-shaped label paper 7 has a through hole for fitting and fixing onto the loading roller 4. The output end of the first motor 6 is directly driven by the loading roller 4, and the output end of the first motor 6 is connected to the take-up roller 5 via a belt.

[0039] By pre-winding the label tape 7 into a disc shape and setting a through hole in the center, rapid loading and replacement of the tape is achieved. In use, the disc is simply placed on the loading roller 4, eliminating the need for complicated tape threading or fixing steps, making operation simple and quick. Simultaneously, the output of the first motor 6 is directly driven by the loading roller 4 and connected to the take-up roller 5 via a belt drive. This ensures the driving stability of the loading roller 4 while reducing transmission impact through the flexibility of the belt drive, resulting in smoother retraction of the take-up roller 5 and preventing tape breakage or uneven label peeling due to sudden tension changes.

[0040] In one embodiment, the housing 1 includes: a first housing 14 and a second housing 15; the first housing 14 is hinged to the mounting plate 11, and the first housing 14 and the mounting plate 11 enclose a first region 12; the second housing 15 is fixedly connected to the mounting plate 11, and the second housing 15 and the mounting plate 11 enclose a second region 13.

[0041] By hinged to the mounting plate 11, the first area 12 (i.e., the paper tape working area) can be easily opened and closed, facilitating paper tape replacement, troubleshooting, or cleaning and maintenance by the user. Simultaneously, the second housing 15 is fixedly connected to the mounting plate 11, ensuring the enclosure and stability of the second area 13 (i.e., the motor area), protecting components such as the motor and preventing accidental user contact. This split-type hinged structure maintains the structural strength and safety of the entire machine while ensuring ease of operation.

[0042] In one embodiment, the first housing 14 includes: a first cover plate 141, a second cover plate 142, and a first side plate 143; the first cover plate 141 is hinged to the upper edge of the mounting plate 11; the lower edge of the first cover plate 141 is hinged to the upper edge of the second cover plate 142; the first side plate 143 is fixedly connected to the edge of the mounting plate 11; both the first cover plate 141 and the second cover plate 142 are in contact with the first side plate 143; the first cover plate 141, the second cover plate 142, the first side plate 143, and the mounting plate 11 together enclose a first region 12.

[0043] The double-hinged structure, where the first cover plate 141 is hinged to the mounting plate 11 and the second cover plate 142, allows for more flexible opening of the first area 12. Users can open only the second cover plate 142 for partial operation or simultaneously open both the first and second cover plates 141 for extensive maintenance. The first side plate 143, acting as a fixed sidewall, forms a stable frame structure together with the mounting plate 11. The abutting contact design between the first and second cover plates 141 and the first side plate 143 ensures sealing and structural rigidity when closed, preventing external dust from entering while maintaining a clean overall appearance.

[0044] In one embodiment, the second housing 15 includes a second side plate 151 and a third cover plate 152; the second side plate 151 is fixedly connected along the edge of the mounting plate 11, and the third cover plate 152 is fixedly connected along the edge of the second side plate 151; the second side plate 151, the third cover plate 152, and the mounting plate 11 together enclose a second region 13.

[0045] The second side plate 151 is fixedly connected to the edge of the mounting plate 11, and together with the third cover plate 152 and the mounting plate 11, it forms a closed second area 13, providing effective protection for the motor. This structure is simple and compact, easy to assemble, and ensures the sealing of the second area 13, preventing external dust or debris from entering the motor area, and also avoiding noise leakage during motor operation, thus improving the user experience.

[0046] In one embodiment, the printing assembly 3 includes: a fixed frame 31, a movable frame 32, a print head 33, and a limiting spring 34; the fixed frame 31 is fixedly connected to the mounting plate 11; the movable frame 32 is hinged to the fixed frame 31; the print head 33 is fixedly connected to the movable frame 32; one end of the limiting spring 34 is fixedly connected to the fixed frame 31, and the other end is fixedly connected to the movable frame 32; the print head 33 is used to abut against the label paper 7 tape.

[0047] The hinged connection between the movable frame 32 and the fixed frame 31, along with the elastic action of the limiting spring 34, allows the print head 33 to elastically abut against the label paper 7. This floating design adapts to paper tapes of varying thicknesses, ensuring that the print head 33 maintains uniform contact pressure with the paper tape, thereby improving print clarity and consistency. Simultaneously, when a paper tape splice or foreign object passes through, the print head 33 automatically lifts to avoid damage to the print head 33 or the paper tape, extending the equipment's lifespan.

[0048] In one embodiment, the printing assembly 3 further includes: a printing roller 35; the printing roller 35 is rotatably connected to the mounting plate 11, the printing roller 35 is located below the print head 33, and can abut against the print head 33; the printing roller 35 is drivenly connected to a second motor 36; the second motor 36 is fixedly connected to the mounting plate 11; the second motor 36 is located in the second region 13.

[0049] The printing roller 35 serves as the counter-roller support for the print head 33, forming a stable printing pressure zone in conjunction with the print head 33 to ensure print quality. The printing roller 35 is independently driven by the second motor 36, separate from the drives of the loading roller 4 and the take-up roller 5, enabling active paper feeding control during the printing process. This independent drive design allows for precise matching of printing speed and paper tape transport speed, avoiding printing deviations caused by tension fluctuations, making it particularly suitable for scenarios requiring precise label position control. Simultaneously, the second motor 36 is also located within the second area 13, maintaining the advantages of dustproof and heat insulation design.

[0050] In one embodiment, the printing assembly 3 further includes a drive roller 37 and a driven roller 38; the drive roller 37 is rotatably connected to the mounting plate 11 and is drive-connected to the second motor 36; the drive roller 37 and the driven roller 38 are in contact; the driven roller 38 is hinged to the mounting plate 11 via a connecting assembly 39; and the driven roller 38 is rotatably connected to the connecting assembly 39.

[0051] The drive roller 37 and the driven roller 38 work together to form an auxiliary paper feeding mechanism, further enhancing the stability and reliability of paper tape transport. The drive roller 37 is driven by a second motor 36 and operates synchronously with the printing roller 35, ensuring that the paper tape maintains constant tension before and after printing. The driven roller 38 is hinged to the mounting plate 11 via a connecting assembly 39, which can adapt to changes in paper tape thickness and always maintain good contact with the drive roller 37, preventing slippage or deviation. This is particularly suitable for long-term continuous printing scenarios, improving paper feeding accuracy and stability.

[0052] In one embodiment, the connecting assembly 39 includes: a hinge base 391 and a snap-fit ​​member 392; the driven roller 38 is rotatably connected to the hinge base 391, and the hinge base 391 is hinged to the mounting plate 11; the hinge base 391 is hinged to the snap-fit ​​member 392; and the snap-fit ​​member 392 is snap-fitted to the printing assembly 3.

[0053] The driven roller 38 is hinged and mounted via hinge bracket 391, allowing it to automatically adjust its position according to changes in paper tape thickness. The snap-fit ​​design between the snap-fit ​​component 392 and the printing assembly 3 enables quick installation and disassembly of the driven roller 38 assembly, facilitating cleaning, maintenance, or replacement. This modular structure simplifies the assembly process, improves production efficiency, and ensures pressure stability between the driven roller 38 and the drive roller 37, guaranteeing reliable paper feeding.

[0054] Specifically, the snap-fit ​​component 392 is a plate body and has a hook 393 and a handle 394; the printing assembly 3 includes a connecting plate 311, which is arranged parallel to the mounting plate 11. The printing roller 35, the movable frame 32, and the drive roller 37 are all rotatably connected to the connecting plate 311. The connecting plate 311 also has a pin 312 for the hook 393 to be snapped and fixed.

[0055] The hook 393 on the snap-fit ​​component 392 engages with the pin 312 on the connecting plate 311 to form a quick-locking structure. Operators can easily lock or unlock the driven roller 38 assembly simply by pinching the handle 394, without the need for tools, greatly simplifying daily maintenance and cleaning. The connecting plate 311, serving as an auxiliary support structure for the printing assembly 3, is set parallel to the mounting plate 11, providing a stable mounting base for the printing roller 35, movable frame 32, drive roller 37, etc., ensuring the parallelism and positional accuracy between the rollers, thereby improving the stability of printing and paper feeding.

[0056] In one embodiment, the take-up roller 5 has a slot, in which a retaining strip 51 is held; the label paper 7 is secured in the slot by the retaining strip 51. The slot and retaining strip 51 on the take-up roller 5 secure the starting end of the label paper 7, solving the problem of traditional take-up rollers requiring manual winding or adhesive fixing. In use, simply insert the end of the paper strip into the slot and press it firmly with the retaining strip 51; the operation is simple, quick, and reliable, preventing the paper strip from loosening during take-up. This mechanical fixing method eliminates the need for tape or adhesive, reducing consumable costs and preventing adhesive residue from contaminating the take-up roller 5 or affecting the neatness of the recycled backing paper.

[0057] In one embodiment, a first guide roller 16 and a second guide roller 17 are rotatably connected to the mounting plate 11; both the first guide roller 16 and the second guide roller 17 are located between the printing assembly 3 and the tape loading roller 4; the first guide roller 16 and the second guide roller 17 are respectively located above and below the printing assembly 3.

[0058] The first guide roller 16 and the second guide roller 17 are respectively positioned above and below the printing assembly 3, forming a complete paper tape guiding path. This vertically distributed guiding structure can effectively regulate the direction of the paper tape, avoid interference or friction between the paper tape and the housing 1 or other components during transmission, and reduce running resistance.

[0059] Specifically, a third guide roller 18 is rotatably connected to the mounting plate 11. The third guide roller 18 is located below the printing roller 35 and is used to prevent the label paper 7 coming out of the separation plate 313 (printing assembly 3) from contacting the printing roller 35. The third guide roller 18 is positioned below the printing roller 35 and is specifically used to guide the label paper 7 coming out of the separation plate 313 (printing assembly 3) to prevent it from contacting the printing roller 35.

[0060] Specifically, a conveying channel 111 for conveying label paper 7 is fixedly connected to the mounting plate 11; The print head 33 is located above the conveying channel 111; a separation plate 313 is fixedly connected to the mounting plate 11, and the separation plate 313 is located downstream of the print head 33 (output end of the print head 33). A strip-shaped opening 321 is opened on the movable frame 32, and the end of the roller 322 is movably locked in the opening 321. The roller 322 is rotatably connected to the opening 321, and the roller 322 can move away from the separation plate 313 along the extension direction of the opening 321. The two ends of the roller 322 can be tightened with nuts to abut and fix the two ends of the roller 322 to the edge of the opening 321.

[0061] Users can easily and intuitively move and lock the roller 322 position simply by tightening or loosening the nut, making the adjustment operation extremely convenient. This mechanical locking method is highly stable and requires no complicated tools, improving the maintainability and user-friendliness of the equipment.

[0062] By positioning the end of roller 322 within the strip-shaped opening 321 of movable frame 32, the position of roller 322 relative to the bending portion 314 of separation plate 313 can be flexibly adjusted. Users or installers can make minute adjustments to the relative gap or clamping force between roller 322 and bending portion 314 based on the thickness, material, and other characteristics of the label paper 7 currently being used, thereby finding the optimal bending curvature and peeling angle to ensure that various labels can be peeled off cleanly and smoothly, achieving dynamic optimization.

[0063] Specifically, opening 321 is made at one end of the movable frame 32.

[0064] The separating plate 313 has a bending portion 314, and the roller 322 abuts in the bending portion 314; after the label paper 7 passes through the print head 33, the label paper 7 passes through the gap between the roller 322 and the separating plate 313, and the roller 322 abuts on the label paper 7; the label paper 7 undergoes a bending motion around the bending portion 314, and the label in the label paper 7 can be separated from the label paper 7 at the edge of the bending portion 314.

[0065] The bending portion 314 of the separating plate 313 moves in conjunction with the roller 322, allowing the bending angle of the label paper 7 on the bending portion 314 to be adjustable, replacing the traditional sharp-angle impact point. Workers can adjust the distance between the roller 322 and the separating plate 313 according to the material of the label paper 7 used, adjusting to a suitable bending angle to ensure complete separation of the label and label paper 7, and to avoid label splashing or skewing during separation.

[0066] The roller 322 directly abuts against the label paper 7 and provides downward pressure, which, together with the bending part 314, constrains and guides the direction of the label paper 7, so that the position of the peeling point is stable.

[0067] The separating plate 313 is a sheet metal part, and its front bending part 314 has an upward structure. The roller 322 presses it in the bending part 314, which further reduces the bending angle of the label paper 7 and makes it easier to separate the label.

[0068] The separation plate 313 is manufactured using sheet metal bending technology, resulting in high structural strength, low manufacturing cost, and good shape consistency of the bent part 314, ensuring a long service life. The entire separation mechanism has few parts, making installation, debugging, and daily cleaning and maintenance very simple, thus reducing manufacturing and subsequent operation and maintenance costs.

[0069] In one embodiment, an adjusting member 8 is also included. The adjusting member 8 is located on the conveying channel 111 and is movable in the width direction of the conveying channel 111. The addition of the adjusting member 8, which is movable along the width direction of the conveying channel 111, allows the mechanism to easily adapt to label paper rolls 7 of different widths. Through simple adjustment, it can be ensured that the label paper 7 maintains the correct alignment with the separating mechanism and printing assembly 3 during conveying, preventing printing skewing, poor peeling, or paper jams caused by misalignment, significantly improving the versatility of the equipment and its compatibility with different specifications of consumables.

[0070] In one embodiment, the adjusting component 8 includes a slider 81 and a limiting plate 82; a strip-shaped through hole 112 for the slider 81 to slide is provided on the conveying channel 111; the extending direction of the strip-shaped through hole 112 is perpendicular to the conveying direction of the conveying channel 111, and the slider 81 can move along the extending direction of the strip-shaped through hole 112; the slider 81 is threadedly connected to a limiting pin 83 that can be locked into the through hole; the limiting plate 82 is fixedly connected to the slider 81. This adjusting component 8 provides a stable and precise lateral position adjustment and locking mechanism. The slider 81 has good guiding properties in the strip-shaped through hole 112, and with the locking of the limiting pin 83 (such as a bolt), the adjusting component 8 can be firmly fixed in the desired position, preventing it from moving under the friction of the label paper 7 being conveyed. This ensures the durable and reliable guiding effect, and the structure is simple and effective.

[0071] In one embodiment, the slider 81 has a limiting block 84, which is movably engaged in the strip-shaped through hole 112. The movable engagement of the limiting block 84 and the strip-shaped through hole 112 makes it difficult for the slider 81 to separate from the conveying channel 111.

[0072] In one embodiment, a fixing plate 113 is fixedly connected to the edge of the strip-shaped through hole 112. The fixing plate 113 has a receiving groove 114 that can accommodate the limiting pin 83. The bottom of the receiving groove 114 has an opening 115 communicating with the strip-shaped through hole 112. One end of the limiting pin 83 abuts against the slider 81, and the other end passes through the strip-shaped through hole 112 and the bottom opening 115 of the receiving groove 114 and is detachably connected to an abutment block 85, which abuts against the bottom opening 115 of the receiving groove 114. By setting a fixing plate 113 with a receiving groove 114 and accommodating and abutting the locking component (nut) of the limiting pin 83 (bolt) therein, an embedded compact locking structure is achieved. This design avoids external protrusions, making the overall appearance cleaner, while preventing the locking component from being accidentally touched and loosened during equipment operation or maintenance, thus enhancing the reliability and safety of the position locking of the adjusting member 8.

[0073] Specifically, the limit pin 83 is a bolt, and the abutment block 85 is a nut.

[0074] In one embodiment, a guide plate 331 is fixedly connected to the lower part of the printhead 33, and the guide plate 331 is spaced apart from the transport channel 111; the distance between the guide plate 331 and the transport channel 111 gradually decreases in the direction closer to the printhead 33. The guide plate 331 with a gradually decreasing gap serves as a guiding device for the label paper 7 entering the area of ​​the printhead 33. Its gradually decreasing gap can initially straighten and guide the potentially warped or uneven label paper 7, allowing it to enter the pressing area between the printhead 33 and the printing roller 35 smoothly and evenly. This effectively reduces the initial risk of paper jams and helps improve the uniformity of printing contact.
