[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but are not to be construed as limiting the present invention.

[0019] Example 1: Please refer to Figure 1-4 The present invention provides a technical solution: a label printing device for a marking machine, comprising a label printer 1, a label conveyor belt 2 is provided on the right side of the label printer 1, a dust removal mechanism 3 is provided on the top of the label conveyor belt 2, and a dust removal mechanism 4 is provided on the top of the label conveyor belt 2 and on the left side of the dust removal mechanism 3; The impurity removal mechanism 3 includes: A fixed column 301 is provided on the top of the label conveyor belt 2; The conductor wheel 304 is movably connected to the top of the label conveyor belt 2 and is located on the left side of the fixed column 301; Two protective covers 312 are provided. The protective covers 312 are arranged on the top of the label transport belt 2 and between the conductor wheel 304 and the fixing column 301 .

[0020] The label paper roll to be printed is placed on the fixed column 301, and the label paper is manually guided through the bottom of the conductor wheel 304 into the label printer 1, and then the label printer 1 is turned on to continuously draw the label paper into the label printer 1 for printing.

[0021] Keeping the label paper in a taut state and feeding it into the label printer 1 for printing is beneficial to improving the printing quality. The back of the label conveyor belt 2 is fixedly connected to a fixed arm 302, and the fixed arm 302 is movably connected to the fixed column 301. The back of the fixed arm 302 is fixedly connected to a servo motor 303, and the output shaft of the servo motor 303 is fixedly connected to the fixed column 301.

[0022] The servo motor 303 controls the rotation of the fixed column 301. The fixed column 301 contacts the inner wall of the label paper roller through friction, so that the servo motor 303 controls the rotation of the label paper roller through the fixed column 301 and adjusts the feeding speed of the label printer 1 so that the label paper is fed into the label printer 1 in a taut state for printing.

[0023] During the production and transportation of label paper, friction will occur, causing the surface of the label paper to be charged. When the charged label paper is printed, the electrostatic field generated by the charge will affect the ink trajectory of the inkjet printing, thereby affecting the printing quality. The front side of the conductor wheel 304 is movably connected to a ground wire 305, and the ground wire 305 is grounded during use.

[0024] Since the servo motor 303 controls the rotation of the label paper roller through the fixed column 301, the label paper is fed into the label printer 1 in a taut state for printing, so that the top of the label paper can be tightly fitted with the bottom of the conductor wheel 304, so that when the top of the label paper contacts the conductor wheel 304, the charge is transferred. The conductor wheel 304 will conduct the transferred charge to the ground through the grounding wire 305, and then remove the charge on the top of the label paper to prevent the charge from affecting the printed inkjet.

[0025] The burrs or fins on the label paper are ground off to prevent them from being mixed between the stamping cylinder and the label paper inside the label printer 1. The front and back sides of the label conveyor belt 2 are fixedly connected to movable guide posts 306. The outer wall of the movable guide posts 306 is movably connected to a movable sleeve 307. The interior of the movable sleeve 307 is movably connected to a knob 308. The top of the knob 308 is fixedly connected to a crank arm 309. The end of the crank arm 309 close to the label conveyor belt 2 is fixedly connected to a first motor 310. The outer wall of the first motor 310 is fixedly connected to the corresponding protective sleeve 312. The output shaft of the first motor 310 is located inside the protective sleeve 312 and is fixedly connected to a grinding wheel 311. The outer wall of the grinding wheel 311 is fixedly connected to a pushing screw 313.

[0026] The rotation of the fixed column 301 is controlled by the servo motor 303, so that the label paper between the label roller and the conductor wheel 304 is straightened, and then the knob 308 is turned to move the movable sleeve 307 to change the position of the crank arm 309 relative to the movable guide column 306, so that the grinding wheel 311 pushes the edge of the label paper to bend, and then the position of the movable sleeve 307 on the movable guide column 306 is fixed by tightening the knob 308, so that the position of the grinding wheel 311 relative to the label paper is fixed. Then, during printing, the first motor 310 drives the grinding wheel 311 so that the grinding wheel 311 can grind the burrs on the top edge of the label paper, and at the same time, the spiral 313 is driven by the grinding wheel 311 to rotate inside the protective cover 312, promoting air flow, and blowing the ground paper debris off the surface of the grinding wheel 311, so as to facilitate continuous grinding of the burrs on the edge of the paper.

[0027] Example 2: Please refer to Figure 1-8 Based on the first embodiment, the present invention provides a technical solution: During the process of label paper rolling, some paper scraps generated when cutting the paper will adhere to the surface of the label paper and be clamped inside the label paper roll. When the label paper is rolled out for printing, these paper scraps will be between the printing roller and the label paper inside the label printer 1, thereby affecting the printing quality. The attachment mechanism 4 includes a rotating roller 401, which is movably connected to the top of the label conveyor belt 2. A hard brush 402 is fixedly connected to the outer wall of the rotating roller 401, and a spiral plate 404 is provided inside the hard brush 402. A third motor 407 is provided on the top of the rotating roller 401, and the third motor 407 is movably connected to the rotating roller 401 through a transmission belt.

[0028] During printing, the third motor 407 drives the rotating roller 401 to rotate through the transmission belt, so that the rotating roller 401 drives the hard brush 402 on the surface to brush the top of the label printer 1. Figure 5 As shown, the hard brush 402 is driven clockwise by the rotating drum 401. When the hard brush 402 encounters raised paper scraps during rotation, it will push them away from the surface of the label paper. Since the servo motor 303 controls the rotation of the label paper drum through the fixed column 301, the label paper is fed into the label printer 1 in a taut state for printing, and the label paper moves from the bottom of the rotating drum 401 to the inside of the label printer 1 in a flat state, which facilitates the cleaning of debris attached to the top of the label paper. At the same time, the spiral plate 404 is driven by the second motor 405 to generate a flowing airflow inside the rotating drum 401, and then a suction airflow is generated through the gap in the outer wall of the rotating drum 401, which will suck the debris swept by the hard brush 402 into the rotating drum 401. At the same time, the airflow pushed by the spiral plate 404 will reduce the air pressure inside the rotating drum 401, so that the label paper is subjected to the suction force generated by the reduced air pressure, and the label paper is close to the rotating drum 401, thereby removing the paper scraps on the surface of the label paper.

[0029] The shredded paper needs to be collected to prevent it from adhering to the surface of the label paper again. The front of the rotating roller 401 is movably connected to a collection box 406, which is fixedly connected to the label conveyor belt 2, and the third motor 407 is fixedly connected to the top of the collection box 406.

[0030] The airflow sucks the paper scraps into the rotating drum 401 and blows them into the collection box 406 for collection.

[0031] When the spiral plate 404 rotates, it will generate suction on the outer wall of the rotating roller 401, so that the label paper is pushed toward the rotating roller 401 by air pressure. Excessive suction will increase the pressure of the label paper on the hard brush 402, increase the wear of the hard brush 402 and the surface of the label paper, and affect the printing quality. A partition plate 403 is provided inside the rotating roller 401. The back of the partition plate 403 is fixedly connected to the label conveyor belt 2. The top of the partition plate 403 is fixedly connected to the second motor 405. The output shaft of the second motor 405 is fixedly connected to the spiral plate 404. The front of the collection box 406 is fixedly connected to the filter screen 408. The inner wall of the rotating roller 401 is fixedly connected to the hollow push plate 412.

[0032] The second motor 405 drives the spiral plate 404 to rotate, generating an air flow inside the rotating drum 401 that flows toward the collection box 406. The dividing plate 403 can block the air flow, making the suction force in the bottom area of ​​the rotating drum 401 at the bottom of the dividing plate 403 weaker, reducing the suction effect of the bottom of the rotating drum 401 on the label paper. The hollow pushing plate 412 is driven by the rotating drum 401 to rotate together inside the rotating drum 401, and will push the broken paper at the bottom of the rotating drum 401 to the top of the dividing plate 403, so that it is affected by the strong air flow generated by the spiral plate 404 and pushed into the collection box 406. The air flow flowing into the collection box 406 will pass through the filter 408, and the filter 408 will filter the debris in the air flow so that it will be intercepted inside the collection box 406 to collect the debris separated from the label paper.

[0033] In addition, the top of the dividing plate 403 is pushed by the spiral plate 404 to generate an airflow, which will rotate the top of the roller 401 to generate a strong suction airflow. At the same time, when the grinding wheel 311 is working, the rotation of the pushing spiral 313 will push the burrs and debris produced by grinding through the inside of the protective cover 312 to the rotating roller 401, so that the burrs and debris can be easily sucked into the inside of the rotating roller 401, and then the inside of the rotating roller 401 enters the collection box 406 to collect the debris, so as to prevent it from floating to the top of the label paper again.

[0034] During the continuous production process, the filter screen 408 will be clogged with excessive debris and needs to be cleaned to ensure continuous operation. The front of the rotating drum 401 is located inside the collection box 406 and is fixedly connected to a scraper rod 409. The front of the dividing plate 403 inside the collection box 406 is fixedly connected to an extension rod 410. The outer wall of the extension rod 410 is located at the corresponding position of the scraper rod 409 and is fixedly connected to a protrusion block 411.

[0035] When the rotating drum 401 rotates, it will synchronously drive the scraping rod 409 to scrape the surface of the filter 408 to prevent continuous accumulation of paper scraps on the inner surface of the filter 408 and ensure air circulation. At the same time, during the rotation of the scraping rod 409, it will be blocked by the protruding block 411 and bend. As the extension rod 410 rotates, the scraping rod 409 will reset during the deformation, causing the scraping rod 409 to shake and shake off the debris attached to the scraping rod 409, thereby improving the cleaning effect of the scraping rod 409 on the filter 408, and thereby improving the collection effect of the collection box 406 on the debris.

[0036] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
