[0046] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0047] In order to enable those skilled in the art of the present technology to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0048] Embodiment 1:

[0049] This embodiment describes the overall structure and basic working principle of the label printer. Specifically:

[0050] As Figure 1 - Figure 2 shown, the present application provides an automatic sticker cutting and character printing machine, including a label machine 1, which has a machine shell 11. The machine shell 11 serves as the main structure of the label machine 1, is used to support the label machine 1, and is placed on the workbench surface. The machine shell 11 can be made of high-strength engineering plastic material, has good impact resistance and wear resistance, and can effectively shield the electromagnetic interference generated by internal electronic components. At the same time, the machine shell 11 is designed as a detachable structure, which is convenient for equipment maintenance and repair;

[0051] At the same time, the internal frame of the machine shell 11 is made of aluminum alloy material, which is precisely processed and strengthened to ensure the stability and rigidity during the printing process. Multiple groups of functional modules are reasonably arranged inside the machine shell 11, including:

[0052] 1. Printing module: Located in the middle area of the printer, including a retractable print head module, a separate module for ribbon recycling and supply, and a printing platform. A 300 PDI thermal transfer print head is adopted to ensure clear printing content.

[0053] 2. Feeding Module: It consists of a feeding motor, feeding rollers, a tension adjusting device, a paper guide, a paper roll bracket, a sticker retraction rubber roller, and a motor. The feeding motor is connected to the feeding rollers and is arranged below the print head. The tension adjusting device, paper guide, and paper roll bracket are arranged at the rear of the printer. The feeding motor drives the feeding rollers to rotate through an accurate control system, smoothly conveying the label paper 2 forward from the paper roll on the paper roll bracket.

[0054] 3. Paper Feeding and Retracting System: The computer sends a printing signal to the device controller, and then the controller presses down the print head. At the same time, the feeding motor drives the feeding rollers to rotate, realizing printing while feeding paper. The automatic paper retracting system, after the controller receives the signal indicating that printing is completed, gives a signal to press down the sticker retraction rubber roller. After pressing down the sticker, it starts the retraction motor to drive the retraction rubber roller to rotate, retracting the sticker to the sticker positioning sensor and automatically stopping.

[0055] It should be noted that the above modules are the basic modules of the label printer 1, and their layouts and functions will not be elaborated in this application.

[0056] Continue to refer to Figure 1 - Figure 2 , on one side of the label printer 1, there is a button 13, and on the label printer 1, there is a screen 14. Thus, the staff can input printing characters through the button 13 as needed, confirm the input of the printing characters through the display of the screen 14, monitor the working state of the label printer 1, and on the side of the machine shell 11, there is a machine cover 12, and this machine cover 12 is suitable for opening to operate the inside of the machine shell 11.

[0057] At the same time, on one side of the label printer 1, there is a paper outlet 15, and this paper outlet 15 is used for outputting the printed label paper 2. At the same time, inside the label printer 1, near the position of the paper outlet 15, there is a cutting mechanism 3, and this cutting mechanism 3 is used to separate the label paper 2 to facilitate the staff to take out the printed label paper 2;

[0058] As Figure 3 - Figure 4 and Figure 6 - Figure 7 shown, the cutting mechanism 3 includes a cutting frame 31 fixedly installed on the inner wall of the machine shell 11. At the bottom of this cutting frame 31, there is a platform 32 fixedly arranged, and this platform 32 is used to support the label paper 2. At the same time, the upper end surface of this platform 32 is at the same height as the lower end of the paper outlet 15, so that the label paper 2 can be smoothly guided out from the paper outlet 15 through the guidance of the platform 32;

[0059] Meanwhile, an electric cylinder 33 is fixedly installed on the top of the cutting frame 31. The output end of the electric cylinder 33 is arranged vertically downward, and a tool holder 34 is fixedly installed on the output end of the electric cylinder 33. A cutter 310 is fixedly arranged at the lower end of the tool holder 34. Thus, the cutter 310 can reciprocate vertically under the drive of the electric cylinder 33 to cut the label paper 2. In this application, the cutter 310 is made of hardened steel;

[0060] And a tool clearance groove 311 is arranged on the platform 32. The tool clearance groove 311 corresponds to the cutter 310. Thus, the cutter 310 is adapted to enter the tool clearance groove 311 during the process of cutting the label paper 2 to completely cut the label paper 2;

[0061] It should be noted that the bottom edge of the cutter 310 is inclined along the length direction. Thus, during the process of the cutter 310 cutting the label paper 2, the bottom edge gradually contacts the label paper 2 until the cutting is completed. Compared with the cutter 310 always contacting the whole label paper 2, it is more beneficial to cut off the label paper 2.

[0062] To facilitate guiding the movement of the cutter 310, as Figure 4 and Figure 7 shown, a side plate 36 is fixedly arranged on the side of the cutting frame 31. A slide rail 35 is fixedly installed on the side plate 36. A slider 37 slides vertically on the slide rail 35, and the tool holder 34 is fixedly installed with the slider 37. Thus, through the cooperation of the slide rail 35 and the slider 37, the sliding of the tool holder 34 is restricted to keep the cutter 310 stable during cutting;

[0063] Meanwhile, to keep the label paper 2 fixed during cutting, a first spring 38 is fixedly installed at the bottom of the tool holder 34. The other end of the first spring 38 is fixedly installed with a pressing plate 39. The pressing plate 39 is adapted to contact the label paper 2 and press the label paper 2, and the position of the pressing plate 39 is lower than the position of the bottom edge of the cutter 310;

[0064] In summary, when it is necessary to cut off the label paper 2, the electric cylinder 33 drives the tool holder 34 to move vertically downward. During the movement of the tool holder 34, the cutter 310 and the pressing plate 39 are driven to move synchronously. Because the position of the pressing plate 39 is lower, the label paper 2 is first pressed on the platform 32. At the same time, as the tool holder 34 continues to move downward, the cutter 310 contacts the label paper 2 and cuts off the pressed label paper 2.

[0065] Embodiment 2:

[0066] During the process of the cutting knife 310 cutting the label paper 2, since there is glue on the label paper 2, during the cutting process, the glue may adhere to the cutting knife 310, and at the same time, the debris generated during cutting will also stick to the cutting knife 310. If not removed in time, it will surely affect the subsequent cutting operation;

[0067] To solve the above problems, as Figure 5 - Figure 6 and Figure 9 shown, a glue cleaning mechanism 5 is provided on the traveling route of the cutting knife 310. The glue cleaning mechanism 5 includes lug ears 321 fixedly installed on both sides of the platform 32. A bearing seat 51 is fixedly installed on the lug ears 321. A glue cleaning pipe 52 is installed between the two bearing seats 51. The glue cleaning pipe 52 is located between the cutting knife 310 and the platform 32. At the same time, a glue cleaning port 521 is provided through the glue cleaning pipe 52, and a wiping part (not marked in the figure) is provided in the glue cleaning port 521;

[0068] In the initial state, the cutting knife 310 is located above the glue cleaning pipe 52. When the label paper 2 needs to be cut, the cutting knife 310 moves down and passes through the glue cleaning port 521 until it reaches the position of the platform 32 to complete the cutting of the label paper 2. Subsequently, the cutting knife 310 retracts to the initial position. During the process of the cutting knife 310 repeatedly passing through the glue cleaning port 521, the wiping part cleans the cutting knife 310 to remove the impurities adhering to the cutting knife 310.

[0069] During the process of cleaning the cutting knife 310, impurities will adhere to the glue cleaning port 521. In order to clean the glue cleaning port 521 in time, as Figure 5 - Figure 6 and Figure 9 shown, a glue suction mechanism 4 is provided on one side of the glue cleaning pipe 52. The glue suction mechanism 4 includes a bracket 43 fixedly installed on the two lug ears 321. A glue suction port 41 is fixedly installed on the two brackets 43. The glue suction port 41 is located on one side of the glue cleaning pipe 52, so as not to affect the rotation of the glue cleaning pipe 52;

[0070] At the same time, the inner side of the glue suction port 41 is close to the outer side of the glue cleaning pipe 52, and a recovery pipe 42 is communicated with the glue suction port 41. The recovery pipe 42 is communicated with an external negative pressure pump, so that the glue cleaning pipe 52 can be rotated to make the glue cleaning port 521 in a horizontal state and aligned with the glue suction port 41. At this time, when the negative pressure pump is started, the impurities in the glue cleaning port 521 can be removed through the glue suction port 41;

[0071] To control the rotation of the glue cleaning pipe 52, as Figure 9 - Figure 10 shown, a rotation mechanism 8 is provided on the glue cleaning pipe 52. The rotation mechanism 8 includes a gear 82 sleeved on the outer circle of the glue cleaning pipe 52, and a rack 81 installed on the tool holder 34. The rack 81 is adapted to reciprocate in the vertical direction along with the tool holder 34;

[0072] It should be noted that the rack 81 is divided into three sections in the vertical direction, namely the first smooth rod section at the upper end, the meshing teeth in the middle, and the second smooth rod section at the lower end. The meshing teeth are adapted to mesh with the gear 82 to drive the gear 82 to rotate, thereby synchronously driving the glue cleaning tube 52 to rotate. In the initial state, the second smooth rod section is aligned with the gear 82, and at this time, the glue cleaning port 521 is in a horizontal state;

[0073] When the tool holder 34 descends, the rack 81 descends synchronously, and the gear 82 is made to cross the second smooth rod section and mesh with the meshing teeth. When the meshing teeth mesh with the gear 82, the gear 82 is driven to rotate, and then the glue cleaning tube 52 is driven to rotate synchronously until the glue cleaning port 521 is in a vertical state. At this time, the cutting tool 310 is still above the glue cleaning port 521;

[0074] Subsequently, the tool holder 34 continues to descend and drives the cutting tool 310 into the glue cleaning port 521. At this time, the gear 82 crosses the meshing teeth and aligns with the first smooth rod section. As the first smooth rod section and the gear 82 cannot mesh, the cutting tool 310 can smoothly pass through the glue cleaning port 521 for cleaning and subsequent cutting of the label paper 2;

[0075] After the label paper 2 is cut, the cutting tool 310 can reset with the tool holder 34 and enter the glue cleaning port 521 for secondary cleaning. Subsequently, it meshes with the gear 82 through the meshing teeth to drive the glue cleaning tube 52 to rotate, so that the glue cleaning port 521 returns to the initial horizontal state, facilitating the next cutting and cleaning operation.

[0076] In order to control the above actions more intelligently, as Figure 10 - Figure 11 shown, a slideway mechanism 6 is provided on the tool holder 34, and a swing rod mechanism 7 is provided on the lug 321. The swing rod mechanism 7 is adapted to cooperate with the slideway mechanism 6 to control the rotation of the glue cleaning tube 52. Specifically:

[0077] The slideway mechanism 6 includes a slide base 61 fixedly installed at the bottom of the tool holder 34. A vertical first slideway 62 is provided on the slide base 61. At the same time, the swing rod mechanism 7 includes a base 71 fixedly installed on the lug 321. A rod body 72 is rotatably installed on the base 71. A sphere 73 is fixedly provided at the upper end of the rod body 72. The sphere 73 is elastic, and in the initial state, the sphere 73 is located at the bottom of the first slideway 62;

[0078] It should be noted that the rack 81 can also be fixedly installed on the slide base 61, so that it can also move synchronously with the movement of the tool holder 34;

[0079] Continue to refer to Figure 11, at the upper end of the first slideway 62, a second slideway 63 is communicatively provided. The bottom position of the second slideway 63 is lower than the bottom position of the first slideway 62, so that the sphere 73 can enter the second slideway 63 from the first slideway 62, but cannot return from the second slideway 63 to the first slideway 62;

[0080] Meanwhile, at the end of the second slideway 63, a vertical third slideway 64 is communicatively provided. The end of the third slideway 64 is communicatively connected to the first slideway 62. At the same time, the bottom position of the third slideway 64 is lower than the bottom position of the second slideway 63, so that the sphere 73 can enter the third slideway 64 from the second slideway 63, but cannot return from the third slideway 64 to the second slideway 63. And at the intersection of the second slideway 63 and the third slideway 64, a stagnation point 67 is provided, and the stagnation point 67 is located in the third slideway 64;

[0081] And an inclined plane 65 is provided in the third slideway 64. The inclined plane 65 is along the direction close to the first slideway 62, and the bottom height gradually increases, and a step is formed at the position communicatively connected to the first slideway 62, so that the sphere 73 can slide from the third slideway 64 into the first slideway 62, but cannot enter the third slideway 64 from the first slideway 62;

[0082] Thus, when the tool holder 34 drives the cutter 310 to descend for cutting, the sphere 73 enters the second slideway 63 from the first slideway 62. When it reaches the position of the stagnation point 67, the cutter 310 finishes cutting the label paper 2. Subsequently, the tool holder 34 resets and drives the sphere 73 to return to the initial position inside the first slideway 62 from the third slideway 64;

[0083] As Figure 8 and Figure 11 shown, a through groove 66 is provided on the inclined plane 65. Meanwhile, a fixed column 68 is fixedly installed on the back of the slide block 61. A second spring 610 is fixedly installed on the fixed column 68. The other end of the second spring 610 is fixedly installed with a sliding column 69, and the sliding column 69 is slidably installed in the through groove 66;

[0084] Meanwhile, a blocking disc 691 is provided on the sliding column 69, and the blocking disc 691 abuts against the back of the through groove 66, so that the height of the part of the sliding column 69 extending into the interior of the through groove 66 (defined as the protruding end) remains consistent. It can be understood that in the initial state, the protruding end can penetrate the through groove 66 and extend into the interior of the third slideway 64. Due to the existence of the inclined plane 65, when the sliding column 69 slides in the through groove 66, the protruding end gradually enters the interior of the through groove 66 from the initial protruding state;

[0085] Thus, when the sphere 73 slides from the third slideway 64 towards the first slideway 62, it will abut against the protruding end of the sliding column 69 and drive the sliding column 69 to move synchronously. Until the protruding end retracts into the interior of the through groove 66, the sphere 73 separates from the protruding end. At this time, the sliding column 69 returns to its initial position under the action of the second spring 610;

[0086] In this embodiment, a contact switch (not shown in the figure) is provided on the protruding end of the sliding column 69. This contact switch is used to control the opening of the negative pressure pump, so as to suck out the impurities in the glue cleaning port 521 through the glue suction port 41;

[0087] It should be noted that when the sphere 73 contacts the contact switch, the glue cleaning tube 52 has rotated in place driven by the meshing teeth, and the glue cleaning port 521 is in a horizontal position. At this time, the pressing of the sphere 73 will start the negative pressure pump, and suck out the impurities in the glue cleaning port 521 through the glue suction port 41. And when the sphere 73 returns to its initial position, the sphere 73 separates from the protruding end of the sliding column 69 to avoid the continuous operation of the negative pressure pump.

[0088] It should be noted that this application also provides a working process of an automatic sticker cutting and lettering printer. Specifically:

[0089] First, the label paper 2 is printed. This step makes the printed content appear on the label paper 2 with a larger size;

[0090] Then, the area where the printed content is located is cut by the cutting inner cutter 9. This step is called the lettering process, and reference can be made to Figure 12 ;

[0091] Finally, a full cut is performed through the cutting mechanism 3 to form a complete label.

[0092] The above are only the preferred embodiments of this application and are not used to limit this application. For those skilled in the art, this application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of this application shall be included in the protection scope of this application.
