Description

Technical Field

[0001] The present invention relates to the technical field of label printing, and in particular to an adjustable label printer based on automatic correction. Background Art

[0002] A label printer, or smart label printer, is a printer that doesn't require a computer connection and features a built-in keyboard or touchscreen interface. It comes with a pre-installed font library and a number of label templates. Similar to a fax machine printhead, label printers transfer a toner coating from a specialized ribbon to paper or other materials using heat. The ribbon's coating can be customized to meet specific needs. Combined with the appropriate print media, this ensures strong adhesion and resists environmental influences.

[0003] Since existing label printers on the market basically adopt a structural design in which the label paper is built into the body, they have the following defects:

[0004] 1. When the label paper roll needs to be replaced, the cover must be opened for manual operation. The label paper must be manually inserted from the back to the front through the paper holder and print head until it reaches the front of the machine body. Manual operation can easily cause problems such as the label paper not being installed in place or not contacting the sensor, which can lead to inaccurate paper feeding during subsequent use.

[0005] 2. When changing label rolls of different widths, the paper holder needs to be manually adjusted to the same width as the label paper each time, which is inefficient. In addition, the manual adjustment accuracy is low and there is a contact error.

[0006] 3. Since the label paper roll is built-in, it is limited by the size of the machine itself and cannot adapt to larger label paper rolls, which affects the application scope of the label printer. Summary of the Invention

[0007] The purpose of the present invention is to provide an adjustable label printer based on automatic correction.

[0045] In the description of the present invention, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are intended only to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific direction, be constructed and operate in a specific direction, and therefore should not be understood as limiting the present invention. The following describes various embodiments of the present invention in detail with reference to the accompanying drawings.

[0046] Example 1

[0047] See also Figures 1 to 13The present invention preferably provides a technical solution: an adjustable label printer based on automatic correction, comprising: a mounting base 2, a wall shell 1 symmetrically arranged on both sides of the mounting base 2, and a detachable top cover 5, the top cover 5 being arranged between the two wall shells 1 and located above the mounting base 2, the mounting base 2, the two wall shells 1 and the top cover 5 together forming the body of the printer; a horizontal bar 211 is arranged at the front end of the wall shell 1, a narrow channel formed between the horizontal bar 211 and the mounting base 2 serves as the discharge port of the printer, and an image acquisition module 4 arranged on the lower surface of the horizontal bar 211; an image acquisition module 4 is arranged inside the mounting base 2 The conveyor belt device 261 is used for conveying the label paper 3; and a carbon ribbon print head mechanism is arranged between the two wall shells 1, and the carbon ribbon print head mechanism is arranged to open and close relative to the mounting seat 2 and is used for printing the label paper 3; a limit paper jam mechanism is arranged on the mounting seat 2, and the limit paper jam mechanism is used to adjust and adapt to the limit pressing of paper of different widths; a feeding platform, the feeding platform is located on one side of the mounting seat 2 and extends to the outside of the wall shell 1; a bottom box 7 is arranged at the end of the mounting seat 2, and a retractable external bracket is provided on the bottom box 7 for supporting and placing the roller 10 where the label paper 3 is located.

[0048] In this application, an improved method of a label printer is provided, such as Figure 1 and 2 For the external structure of the whole machine, combined Figure 3 The internal disassembly diagram shows that the conveyor belt device 261 inside the mounting base 2, the feeding platform and the external bracket constitute the feeding system of the label paper 3, and cooperate with the carbon ribbon print head mechanism that can be automatically opened and closed. By placing the bracket where the label paper 3 is installed externally, firstly, through the automatic feeding of the feeding platform, when the label paper 3 needs to be replaced, the carbon ribbon print head mechanism is automatically lifted. At this time, you only need to replace the label paper 3 on the external bracket without opening the cover. Secondly, the function of the external bracket is to facilitate the installation of large rolls of label paper 3.

[0049] The automatic correction of the label printer is reflected in the following aspects: first, through the set limit paper jam mechanism, it can automatically adapt to label papers 3 of different widths for adjustment and complete the adaptive limit clamping process. When the label paper 3 needs to be replaced, the label paper 3 is automatically transported in the machine body without opening the cover, and the automatic loading process of the limit paper jam improves work efficiency while avoiding the adverse effects of manual loading by opening the cover.

[0050] Second, the image acquisition module 4 provided at the discharge port is used to acquire the image at the position and transmit the image information to the control processor unit inside the label printer. The control processor unit receives the information and compares it with the image at the storage module. If it meets the requirements, the label printing is performed. If it does not meet the requirements, the feeding platform continues to feed until the image acquisition is qualified, and the feed printing is started. Figure 1 and 2As shown, the label paper 3 is composed of several printing areas composed of several dividing lines. When the dividing line where the mounting seat 2 is located is placed at the position of the image acquisition module 4, the image at this position is used as the printing trigger condition, that is, it is set as the image where the storage module is located.

[0051] Furthermore, an observation window 6 is provided on the top of the top cover 5 to facilitate personnel to observe the internal working conditions of the printer.

[0052] Furthermore, through grooves are evenly arranged on the conveyor belt of the conveyor belt device 261, and a negative pressure device is provided inside the conveyor belt body to allow the label paper 3 to be adsorbed on the upper surface of the conveyor belt for smooth transportation.

[0053] Example 2

[0054] As another embodiment of the present invention, the limiting paper jam mechanism includes a transition seat 811, two grooves 813 opened on the transition seat 811, and a limiting paper jam head assembly respectively arranged on both sides of the transition seat 811; each group of limiting paper jam head assemblies includes a rectangular plate 132 fixedly set on the side wall of the transition seat 811, and a gear connecting rod shifting mechanism installed on the side of the rectangular plate 132 close to the discharge port, and a limiting card head is set on the gear connecting rod shifting mechanism.

[0055] In this embodiment, a paper jamming mechanism is provided. Figure 1 、 4 , 8, 9 and 10, first, the limit jamming head assembly is driven to move by the action of the gear-link shifting mechanism. When the label paper 3 is replaced, the limit jamming head assembly is reset to both sides to facilitate the passage of the replaced label paper 3. When the replaced label paper 3 is fed under the action of the feeding platform and passes through the limit jamming mechanism and continues to extend to the position of the conveyor belt device 261, the gear-link shifting mechanism drives the limit jamming head assemblies on both sides to run towards each other and approach the edge of the label paper 3 until the limit jamming of the label paper 3 is completed, thereby ensuring the smooth, orderly and edge wrinkle-free operation of the label paper 3 during transportation.

[0056] Furthermore, the gear connecting rod shifting mechanism includes a fixed sleeve 140, a retractable movable rod 141 passing through the middle of the fixed sleeve 140, and a hinge 142 arranged at the end of the movable rod 141 near the rectangular plate 132, and a centrally deflected driving rod 137 is installed on the hinge 142; a rotatable first transmission tooth 133 and a second transmission tooth 134 are provided on the rectangular plate 132, the first transmission tooth 133 and the second transmission tooth 134 are engaged for transmission, and the diameter of the second transmission tooth 134 is smaller than the diameter of the first transmission tooth 133, and the second transmission rod 136 and the first transmission rod 135 are respectively rotatably installed on the first transmission tooth 133 and the second transmission tooth 134 through a pin shaft, and the second transmission rod 136 and the first transmission rod 135 are respectively rotatably connected to the two ends of the driving rod 137 near the ends of the movable rod 141; and it also includes a third motor 139 arranged on the back of the rectangular plate 132 for driving the first transmission tooth 133 to rotate.

[0057] The gear link shifting mechanism provided has the following characteristics: Figure 8 As shown, since the diameter of the first transmission tooth 133 is greater than the diameter of the second transmission tooth 134, and the second transmission rod 136 and the first transmission rod 135 act together on the driving rod 137, and under the connection of the hinge 142, the position-limiting jamming head assembly at the end of the movable rod 141 is pushed to move telescopically. Its design utilizes the diameter difference between the first transmission tooth 133 and the second transmission tooth 134, and under the connection of the first transmission rod 135 and the second transmission rod 136, the deflection and movement distance of the driving rod 137 are controlled. During the initial operation, the first transmission tooth 133 and the second transmission tooth 134 are connected. When the transmission tooth 133 and the second transmission tooth 134 act together to drive the rod 137 and make their directions consistent, the running speed of the limit jam head assembly where the movable rod 141 is located is faster. When the second transmission tooth 134 rotates over 180° and acts in the opposite direction to drive the rod 137, the second transmission rod 136 where the first transmission tooth 133 is located is still in the previous state and acts on the drive rod 137. At this time, the speed of the limit jam head assembly becomes slow to move forward. Due to the slow approach, the limit jam head assembly can accurately act on both sides of the edge of the label paper 3.

[0058] Furthermore, the limit chuck includes a first mounting member 143 which can slide within the groove 813 in a limited manner. The first mounting member 143 has a "U" - shaped structure. An installation groove 167 is provided in the vertical section of the first mounting member 143. A second mounting strip 166 is installed inside the installation groove 167, and second mounting members 162 are provided on both sides of the second mounting strip 166. A number of groups of limit wheels 163 are installed inside each second mounting member 162. A laser emitter 161 and a laser receiver 165 are provided at the upper and lower parts of the first mounting member 143. The output end of the laser emitter 161 acts on the laser receiver 165, and the limiting part of the limit wheel 163, the output end of the laser emitter 161 and the input end of the laser receiver 165 are coplanar.

[0059] Through the provided limit chuck assembly, as Figure 9 and 10 shown, the limiting part of the limit wheel 163 and the label paper 3 are in the same plane. Under the action of the gear - link displacement mechanism, when the limit wheel 163 where the second mounting member 162 is located slowly approaches the edge of the label paper 3, through the further provided laser emitter 161 and laser receiver 165, and because the docking light rays where the limiting part of the limit wheel 163, the laser emitter 161 and the laser receiver 165 are coplanar, when the light ray emitted by the laser emitter 161 touches the edge of the label paper 3, it is quickly blocked. At this time, the laser receiver 165 cannot receive the light signal of the laser emitter 161, that is, the edge where the label paper 3 is located exactly acts on the limiting part of the limit wheel 163. At this time, the control processor unit receives the signal and controls the gear - link displacement mechanism to stop working. At this time, under the action of a number of limit wheels 163 on both sides, the label paper 3 can be horizontally limited left and right during transportation.

[0060] Embodiment 3

[0061] As other embodiments of the present invention, an extension member 153 is provided on each of the first mounting members 143. A cylinder 154 is installed on the extension member 153. The power output end of the cylinder 154 is fixed with a second connecting member 155. The second connecting member 155 has an "L" - shaped structure. A telescopic long rod 156 is installed on the vertical section of the second connecting member 155. Equally - spaced installation wheels 159 are linearly distributed on the long rod 156. Second springs 157 are provided on the outer wall of the long rod 156 between the second connecting member 155 and an adjacent installation wheel fifteen - nine and between adjacent installation wheels 159. The installation wheel 159 farthest from the second connecting member 155 is fixedly connected to the end of the long rod 156. A roller 158 is installed on the outer wall of the circumference of each installation wheel 159. A backing plate 812 is also provided on the transition seat 811.

[0062] In this embodiment, as Figure 4 、 8As shown in Figures 9 and 10, by further setting up several mounting wheels 159, when the limiting clamping head assembly approaches the edge of the label paper 3 and completes the paper clamping, the mounting wheels 159 at the first position on both sides conflict with each other, thereby causing the long rod 156 to move backward relative to the second connecting member 155, and compressing several second springs 157, so that several rollers 158 on both sides are evenly distributed on the upper surface of the label paper 3, and drive the cylinder 154 to drive the second connecting member 155 to move downward. By utilizing the action of several mounting wheels 159, the label paper 3 can be further flattened in the vertical direction. Combined with the left and right limits of the limiting clamping head assembly in Example 2, the smooth and stable conveying process of the label paper 3 is further guaranteed, and the wrinkles and creases can be flattened at the same time.

[0063] Furthermore, the feeding platform includes a support platform 916 fixed on the front side of the transition seat 811, the support platform 916 is coplanar with the pad 812, and a long slot frame 913 is arranged in the middle of the transition seat 811, the end of the long slot frame 913 away from the conveyor belt device 261 passes through and extends to the tail end of the support platform 916, a conveyor belt 914 is installed inside the long slot frame 913, a number of transmission blocks 915 are evenly distributed on the conveyor belt 914, a damping layer is provided on the upper surface of the transmission block 915, which is used to drive the label paper 3 to be transported forward, and a first motor 917 is provided at the end of the long slot frame 913, the first motor 917 is used to drive the conveyor belt 914 for transportation, and a limit bar 911 is provided on the support platform 916, and the narrow channel formed between the limit bar 911 and the support platform 916 constitutes the feed port of the printer.

[0064] like Figure 1 、 3 As shown in Figure 4, when the label paper 3 needs to be put on the belt, the front end of the label paper 3 is inserted into the feed port where the limit strip 911 is located, and then the first motor 917 works to drive the conveyor belt 914 to transport forward, that is, several transmission blocks 915 circulate forward in sequence. Since a damping layer is provided on the upper surface of the transmission block 915, when it acts on the lower surface of the label paper 3, due to friction resistance, it can drive the label paper 3 to perform the feeding process.
