Description

Technical Field

[0001] This utility model relates to the field of label printer technology, and in particular to a label printer and its highly integrated core assembly. Background Technology

[0002] Currently, label printers are increasingly used in daily life, including in supermarkets, shopping malls, and homes, and they are becoming increasingly smaller. Most existing label printers are thermal printers, meaning they use a semiconductor heating element, such as a thermal pad, mounted on the print head. The print head heats up and contacts the thermal paper to print the desired pattern and text. During printing, the paper is moved by a roller inside the printer. The thermal pad is located on the printing side of the paper. When the contact surfaces of the paper and the roller, and the thermal pad and the paper, are parallel, a clear image can be printed on the paper.

[0003] Current printers require customers to scan barcodes or manually select different consumables, making the process cumbersome and lacking in intelligence. Furthermore, the core components of existing printers are primarily limited to printhead functionality, resulting in large printer sizes that fail to meet market demands.

[0004] Furthermore, in practical applications, thermal printers need to print paper of various widths. Some printers on the market lack width adjustment functions, while others, although possessing width adjustment functions, offer stepped width adjustment, and many of these adjustments are based on one side rather than centering. Moreover, existing width adjustment components are mostly mounted on the upper housing assembly, not integrated into the main unit, which is inconvenient both in assembly and production processes and in customer operation.

[0005] Furthermore, most existing printers use traditional long ribbon cables to set up photoelectric detection units. For example, the traditional long ribbon cable starts from the photoelectric point on the top cover, goes around the entire top cover, then around the rotation point between the top cover and the upper housing, and extends to insert into the main control board in the lower housing. The wiring and fixing of the ribbon cable are relatively troublesome, and the reliability is also poor, resulting in low assembly and production efficiency, which indirectly leads to increased costs.

[0006] Therefore, it is evident that the existing label printers still have inconveniences and shortcomings in terms of structure, method, and use, and urgently need further improvement. How to create a new label printer and its highly integrated core components, integrating multiple functions such as printing, cover opening, centering and width adjustment, photoelectric recognition, and anti-counterfeiting recognition through improvements to the core components, with high integration, and providing favorable conditions for the compact design of the printer, has become a pressing goal for the industry. Utility Model Content

[0007] The technical problem to be solved by this utility model is to provide a highly integrated core component for a label printer, which can integrate multiple functions such as printing, cover opening, centering and width adjustment, photoelectric recognition, and anti-counterfeiting recognition. The high degree of integration provides favorable conditions for the compact design of the printer, thereby overcoming the shortcomings of existing label printers.

[0008] To solve the above-mentioned technical problems, this utility model provides a highly integrated core assembly for a label printer, including a core base and a push plate, a movable back plate, a compression spring, a printhead base plate and a printhead ceramic plate arranged sequentially on the upper part of the core base, a gear transmission mechanism arranged on one side of the core base, and a motor arranged on the lower part of the core base for driving the gear transmission mechanism;

[0009] The movable back plate has side plates on both sides, and the upper part of the two side plates has symmetrical L-shaped grooves for locking the glue roller shaft when the label printer cover is closed.

[0010] The bottom of the movable back plate and the printhead substrate are both movably disposed in the limiting groove of the mechanism base. The compression spring is disposed between the movable back plate and the printhead substrate. The printhead ceramic plate is bonded to the other side of the printhead substrate. The push plate is located on the other side of the movable back plate, with its bottom abutting against the bottom of the mechanism base and its upper part abutting against the upper part of the movable back plate. In its natural state, the push plate causes the printhead ceramic plate to adhere to the rubber roller. When the upper part of the push plate moves downward under the action of external force, it pushes the upper part of the movable back plate to rotate towards the printhead substrate side, causing the L-shaped groove on the side plate of the movable back plate to rotate, thereby causing the rubber roller shaft to disengage from the L-shaped groove.

[0011] In a further improvement, the bottom of the movement base is provided with an inclined surface that slopes downwards. A width adjustment mechanism is provided on the inclined surface. The width adjustment mechanism includes a left baffle assembly, a right baffle assembly, and a transmission assembly. The transmission assembly includes a central gear and an upper rack and a lower rack respectively disposed on its upper and lower sides and meshing with it. The upper rack and the lower rack are confined inside the groove in the inclined surface. The left baffle assembly and the right baffle assembly are respectively connected to the lower rack and the upper rack. When the left baffle assembly or the right baffle assembly is driven to move left or right, the right baffle assembly moves towards or away from the left baffle assembly, realizing stepless adjustment of the width between the right baffle assembly and the left baffle assembly.

[0012] In a further improvement, the width adjustment mechanism also includes two tension springs. One end of the first tension spring is connected to the upper rack and the other end is connected to the movement base. One end of the second tension spring is connected to the lower rack and the other end is connected to the movement base. The tension directions of the first and second tension springs are opposite, which is used to realize the automatic adjustment of the distance between the right baffle assembly and the left baffle assembly.

[0013] In a further improvement, the left baffle assembly includes a left baffle plate and a left baffle plate cover. One side of the left baffle plate is flat and is used to fit tightly against the side of the consumable roll. The other side of the left baffle plate is provided with a cavity. An anti-counterfeiting coil is provided in the cavity for detecting RFID tags set in the consumable roll. The left baffle plate cover is used to cover the opening of the cavity.

[0014] In a further improvement, the mechanism assembly also includes two FPC lines for connecting to the controller. One FPC line is located on the side of the mechanism base, and its contacts are used to connect to the spring pins on the label printer cover. The other FPC line is located on the top of the mechanism base and is connected to the receiving photoelectric sensor to receive the transmission signal from the transmitting photoelectric sensor on the label printer cover.

[0015] In a further improvement, the top of the printhead substrate is provided with a protruding plate extending toward the top of the printhead ceramic plate. The edge of the protruding plate protrudes 0.1-0.5mm beyond the edge of the printhead ceramic plate, and the edge of the protruding plate is rounded.

[0016] As a further improvement of this application, this utility model also provides a label printer, which includes the highly integrated core assembly of the label printer described above.

[0017] In a further improvement, the label printer includes an inner cavity formed by an upper housing, a lower housing, and an upper cover. One side of the inner cavity corresponding to the upper cover is used to install a consumable roll. The highly integrated mechanism assembly is located on the other side of the inner cavity. The left and right baffle assemblies of the width adjustment mechanism are used to clamp the consumable roll in the center.

[0018] The upper cover is provided with a rubber roller. The roller shaft of the rubber roller is hooked by the L-shaped groove after the upper cover is fastened. The end of the rubber roller is provided with a gear, which is used to mesh with the gear transmission mechanism after the upper cover is fastened, so as to drive the rubber roller to rotate.

[0019] The controller and battery are located at the lower part of the movement base.

[0020] In a further improvement, the upper cover is also provided with a photoelectric emitter and a spring pin connected thereto. After the upper cover is fastened, the photoelectric emitter is aligned with the photoelectric receiver on the movement assembly. After the upper cover is fastened, the spring pin is connected to the FPC line contact on the movement assembly to form a photoelectric circuit. Furthermore, the photoelectric emitter also integrates a reflective photoelectric emitter.

[0021] Further improvements include a power button, an open cover button, a print button, and an indicator light on the upper surface of the upper housing. The bottom of the open cover button corresponds to the upper part of the push plate and is used to drive the push plate to rotate, thereby opening the upper cover. The print button is used to control the printing and retraction of consumables.

[0022] With this design, the present invention has at least the following advantages:

[0023] 1. The highly integrated core assembly of this label printer, through improvements to the core base and its components, integrates multiple functions in addition to traditional printing functions, such as easy cover opening, centering and width adjustment, anti-counterfeiting identification, photoelectric positioning identification, and consumable paper ejection. The scientifically designed and rationally arranged components provide reliable conditions for the compact design of the printer. It also enables easy opening and closing of the top cover, stepless centering and width adjustment for consumable rolls from 24-80mm, rapid identification of consumable authenticity and specifications, reliable assurance for consumable printing, and intelligent control of paper feed, ensuring accurate printing position, clear content, and minimal waste.

[0024] 2. Furthermore, by setting the photoelectric recognition mechanism to a spring-loaded contact mode, the ribbon cable is shortened, reducing the hassle of winding long ribbon cables. This modularizes the entire machine, eliminating interconnections, simplifying assembly, increasing assembly efficiency, and making it easy and convenient to use. Attached Figure Description

[0040] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0041] See attached document Figure 1 and 2 As shown, the label printer in this embodiment has a compact structure and small size, meeting the market demand for miniaturization. The specific structure of the label printer is as follows:

[0042] The label printer includes an upper housing 1, a lower housing 2, and an upper cover 3. The upper housing 1 and lower housing 2 are fixedly connected, and the upper cover 3 is movably hinged to the upper housing 1, with a maximum rotation angle of 90 degrees. The upper cover 3 can be opened and closed relative to the upper housing 1. When opened, it is used for installing and removing consumable rolls; when closed, it is used for normal consumable printing. After the upper cover 3 is fastened to the upper housing 1, an inner cavity is formed by the upper housing 1, lower housing 2, and upper cover 3.

[0043] One side of the inner cavity corresponding to the upper cover 3 is used to install the consumable roll 19, meaning the height of the label printer is determined by the diameter of the consumable roll 19. The other side of the inner cavity is equipped with a highly integrated core assembly 4 and a controller 16 and a battery 18 located at its bottom.

[0044] See attached document Figures 3 to 6 As shown, the highly integrated mechanism assembly 4 in this embodiment includes a mechanism base 13 and a push plate 14, a movable back plate 10, a compression spring 9, a printhead substrate 7, and a printhead ceramic plate 8 sequentially arranged on the upper part of the mechanism base 13, a gear transmission mechanism 12 disposed on one side of the mechanism base 13, and a motor 11 disposed on the lower part of the mechanism base 13 for driving the gear transmission mechanism 13. The motor 11 can drive the gear transmission system 12 to achieve forward and reverse rotation, thereby realizing the paper feeding and paper ejection functions.

[0045] See attached document Figure 4 As shown, the top of the printhead substrate 7 is provided with a protruding plate 71 extending toward the top of the printhead ceramic plate 8. The edge of the protruding plate 71 protrudes 0.1-0.5mm beyond the edge of the printhead ceramic plate 8, and the edge of the protruding plate 71 is rounded to ensure that the sharp right-angled edge of the printhead ceramic plate 8 will not scratch the face paper of the die-cut label when the paper is ejected, thereby achieving smooth paper ejection. The presence of the rounded corners also ensures smooth paper feeding.

[0046] See attached document Figure 7 As shown, the movable back plate 10 has side plates 101 on both sides, and each of the two side plates 101 has symmetrical L-shaped grooves 102 on its upper part for hooking the rubber roller shaft when the label printer cover is closed. The bottom of the movable back plate 10 and the printhead base plate 7 are movably disposed in the limiting groove of the mechanism base 13, and the compression spring 9 is disposed between the movable back plate 10 and the printhead base plate 7. The printhead ceramic plate 8 is bonded to the other side of the printhead base plate 7. The push plate 14 is located on the other side of the movable back plate 10, with its bottom abutting against the bottom of the mechanism base 13 and its upper part abutting against the upper part of the movable back plate 10. Under the action of the compression spring 9, the push plate 14 in its natural state causes the printhead ceramic plate 8 to adhere to the rubber roller 20, ensuring that the contact surfaces of the consumable printing paper and the rubber roller 20 and the contact surfaces of the printhead ceramic plate 8 and the consumable printing paper are in a parallel state, ensuring clear printing patterns and achieving normal printing function. When the upper part of the push plate 14 moves downward under the action of external force, it pushes the upper part of the movable back plate 10 to rotate towards the print head substrate side, causing the L-shaped groove 102 on the side plate of the movable back plate 10 to rotate, thereby causing the rubber roller shaft to disengage from the L-shaped groove 102, thus realizing the opening of the upper cover 3.

[0047] See attached document Figure 8 As shown, in this embodiment, the bottom of the mechanism base 13 is also provided with an inclined surface 131 that is inclined downwards, and the inclined surface 131 is inclined towards the bottom of the consumable roll 19. A width adjustment mechanism 15 is provided on the inclined surface 131.

[0048] See attached document Figure 9 and 10 As shown, the width adjustment mechanism 15 includes a left baffle assembly 151, a right baffle assembly 152, and a transmission assembly 153. The transmission assembly 153 includes a central gear 1531 and an upper rack 1532 and a lower rack 1533 respectively disposed on its upper and lower sides and meshing with it. The upper rack 1532 and the lower rack 1533 are confined within a groove in the inclined surface 131. The left baffle assembly 151 and the right baffle assembly 152 are respectively connected to the lower rack 1533 and the upper rack 1532. When the left baffle assembly 151 is manually driven to move left or right, the right baffle assembly 152 moves towards or away from the left baffle assembly 151, realizing stepless adjustment of the width between the right baffle assembly 152 and the left baffle assembly 151. In this embodiment, a stepless centering width adjustment function of 24-80mm can be achieved. Of course, driving the right baffle assembly 152 to move left or right can also achieve stepless centering adjustment.

[0049] Preferably, the width adjustment mechanism 15 further includes two tension springs. One end of the first tension spring 154 is connected to the upper rack 1532, and the other end is connected to the mechanism base 13. One end of the second tension spring 155 is connected to the lower rack 1533, and the other end is connected to the mechanism base 13. The tension directions of the first tension spring 154 and the second tension spring 155 are opposite, and both provide tension towards the center, which is used to realize the automatic adjustment of the distance between the right baffle assembly 152 and the left baffle assembly 151, so as to achieve automatic centering and clamping of the consumable roll 19.

[0050] For a better option, see the appendix. Figure 11 As shown, the left baffle assembly 151 includes a left baffle 1511 and a left baffle cover 1512. One side of the left baffle 1511 is flat and is used to fit tightly against the side of the consumable roll 19. The other side of the left baffle 1511 is provided with a cavity. An anti-counterfeiting coil 1513 connected to the control board 16 is provided in the cavity for detecting the RFID tag 191 set in the consumable roll 19. The left baffle cover 1512 is used to cover the opening of the cavity.

[0051] Consumable roll 19 used with the label printer of this embodiment is attached. Figure 13 and 14As shown, the assembly includes a core 191, consumable 192, a stopper 193, and an RFID tag 194. The RFID tag 194 stores consumable information, is used to read and write updates to consumable parameters, and automatically matches editing interactions, printing processes, and paper feed positions, while also performing anti-counterfeiting verification. The RFID tag 194 is affixed to the inside of the stopper 193, which matches the core 191, ensuring a flat side for the consumable roll 19 and facilitating its integration with the width adjustment mechanism 15. When the consumable roll 19 is loaded into the machine, one side of the stopper 193 abuts against one side of the left baffle assembly 151. The anti-counterfeiting coil 1513 in the left baffle assembly 151 detects and identifies the RFID tag 194 in the consumable roll 19, completing the anti-counterfeiting function detection.

[0052] Also, please refer to the appendix. Figure 5 and 6 As shown, the mechanism assembly 4 also includes two FPC lines 17 for connecting to the controller 16. One FPC line 17 is located on the side of the mechanism base 13, and a contact 171 is provided on it for connecting to the spring pin 23 on the top cover of the label printer. The other FPC line 17 is located on the top of the mechanism base 13 and is connected to the receiving photoelectric 21 for receiving the transmission signal of the transmitting photoelectric 22 on the top cover of the label printer.

[0053] See attached document Figure 12 As shown, in this embodiment, the upper cover 3 is provided with a rubber roller 20. After the upper cover 3 is fastened, the roller shaft of the rubber roller 20 engages with the L-shaped groove 102. The end of the rubber roller 20 is provided with a gear 201, which is used to mesh with the gear transmission mechanism 12 after the upper cover 3 is fastened, so as to drive the rubber roller 20 to rotate in both directions, thereby realizing the printing and retraction of consumables.

[0054] The upper cover 3 is also equipped with a photoelectric emitter 22 and a spring pin 23 connected to it. After the upper cover 3 is closed, the photoelectric emitter 22 aligns with the photoelectric receiver 21 on the mechanism assembly 4. After the upper cover 3 is closed, the spring pin 23 connects to the FPC line contact 171 on the mechanism assembly 4, forming a circuit path. The control board 16 detects that the upper cover 3 is closed, and at the same time, the photoelectric emitter 22 emits light. The emitted light is received by the photoelectric receiver 21. During printing, the control board 16 determines the presence or absence of consumables and the gaps in the die-cut stickers based on the intensity of the collected light, so as to achieve accurate printing of consumables. In addition, the photoelectric emitter 22 also integrates a reflective photoelectric sensor to receive the intensity of the light reflected by the consumables, so as to detect the die-cut gap label and consumables with black label photoelectric stickers, making the detection more accurate and the application wider. When the upper cover 3 is opened, the spring pin 23 disconnects from the FPC line contact 172, the circuit is broken, and the control board 16 detects that the cover is open.

[0055] See attached document Figure 1 As shown, in this embodiment, the upper surface of the upper housing 1 is provided with a power button 5, a cover opening button 6, a print button 24, and an indicator light 25. The power button 5 is used to turn the printer on and off. The bottom of the cover opening button 6 corresponds to the upper part of the push plate 14 and is used to drive the push plate 14 to rotate, thereby opening the upper cover 3. That is, when the cover opening button 6 is pressed, the push plate 14 is rotated clockwise, and the push plate 14 will in turn press the movable back plate 10 to rotate clockwise to the right, causing the L-shaped grooves 102 on both sides of the movable back plate 10 to rotate clockwise as well, until the rubber roller 20 disengages from the L-shaped groove 102. Under the pressure of the compression spring 9, the rubber roller 20 is pushed away from the upper cover 3, thus opening the cover. After releasing the pressure on the cover opening button 6, the movable back plate 10 rotates counterclockwise under the action of the compression spring 9, thereby driving the push plate 14 to rotate counterclockwise, and the cover opening button 6 returns to its original position. The print button 24 is used to control the printing and retraction of consumables; for example, a single click initiates normal printing, while a double click ejects the paper. The indicator light 25 indicates the printer's operating status.

[0056] This utility model's label printer's core assembly integrates printing, width adjustment, anti-counterfeiting detection, photoelectric identification, cover opening, paper ejection, and transmission functions into a single modular design, resulting in high integration and assembly efficiency. Furthermore, the paper ejection function prevents consumable waste and reduces costs. By adapting to consumable rolls with RFID tags, it can accurately and quickly identify consumable information, providing reliable conditions for precise printing.

[0057] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes or alterations made by those skilled in the art using the above-disclosed technical content shall fall within the protection scope of the present utility model.
