Description

Technical Field

[0001] This invention relates to the field of label printing technology, and more particularly to a label production and printing apparatus. Background Technology

[0002] In today's commercial and industrial sectors, labels serve as an important carrier for product identification and information transmission, and are widely used in various scenarios such as commodity packaging, logistics and transportation, and asset management. With the continuous growth of market demand and the trend of product diversification, higher requirements are being placed on the production efficiency and printing quality of labels.

[0003] Traditional label production and printing methods often have limitations. In the label conveying stage, many devices struggle to achieve stable and precise label paper feeding. Some conveying devices have simple structures and cannot flexibly adjust the conveying pressure according to factors such as the material and thickness of the label paper. This can lead to problems such as label paper slippage and misalignment during conveying, affecting subsequent printing and cutting accuracy. For example, when the label paper surface is relatively smooth or thin, the friction between the conveyor rollers and the label paper is insufficient, easily causing poor label paper feeding and resulting in misaligned printed patterns.

[0004] To address the aforementioned issues and improve the efficiency and quality of label production and printing, developing a label production and printing device capable of stable label paper feeding is of significant practical importance. This device will effectively enhance the automation and production efficiency of label production, meeting the diverse market demands for high-quality labels. Summary of the Invention

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A label production and printing device includes a base. An elastic element is installed on the top outer wall of the base. The elastic element includes a mounting shell and a sliding rod. The mounting shell is fixed to the top outer wall of the base. The sliding rod is movably connected to the inner wall of a through hole opened in the top of the mounting shell. A permanent magnet is fixed to the bottom of the sliding rod. An electromagnet is fixed to the bottom inner wall of the mounting shell. An antimagnetic spring is fixed between the top of the electromagnet and the bottom of the permanent magnet. Support rollers are installed on the top of the two sliding rods. The support rollers and the conveying rollers work together to convey label paper.

[0008] As a further embodiment of the present invention: a vertical plate is fixed to the top outer wall of the base, and a drive motor is fixed to one side of the outer wall of the vertical plate, and the output end of the drive motor is connected to a conveying roller through a coupling.

[0011] As a further embodiment of the present invention: the support roller includes a connecting block and a sliding plate. The connecting block is fixed to the top of the sliding rod, and the sliding plate is movably connected to the side wall of the connecting block. The outer walls of the two sliding plates are respectively movably connected to sleeve one and sleeve two, and a rotating shaft is movably connected between sleeve one and sleeve two.

[0012] As a further embodiment of the present invention: a second drive motor is fixed to one inner wall of the second sleeve, and the output end of the second drive motor is connected to one end of the rotating shaft through a coupling. A cylindrical roller and a conical roller are fixed to the outer wall of the rotating shaft respectively, and the cylindrical roller and the conical roller are in close contact with each other.

[0013] As a further embodiment of the present invention: a guide plate is fixed to the top outer wall of the base, and a movable sleeve is movably connected to the outer wall of the guide plate. A large gear and a small gear are movably connected to the side wall of the movable sleeve, and the large gear and the small gear mesh with each other.

[0016] As a further embodiment of the present invention: a controller is fixed to the top outer wall of the base.

[0017] Compared with the prior art, the present invention provides a label production and printing device, which has the following beneficial effects:

[0018] 1. By utilizing the elastic force of the non-magnetic spring in the elastic component and the repulsive force generated by the electromagnet being energized, the support roller and the conveying roller are tightly fitted together, which improves the friction between the two and ensures the stability and reliability of the conveying of printed label paper, effectively avoiding the problem of label paper accumulation.

[0019] 2. When it is necessary to cut the label paper, by changing the direction of the magnetic pole of one of the electromagnets, the two slides are tilted, which in turn drives the connecting frame to tilt, driving the large gear and the small gear to rotate, so that the rotating cutter rotates at a large angle to cut the label paper, which greatly improves the cutting efficiency.

[0020] 3. A vision camera is used to identify the label markings on the label paper. Once the label markings are identified, the controller controls the drive motor to stop feeding the label paper before proceeding with the cutting process. This ensures the accuracy of the label paper cutting length and improves product quality.

[0021] 4. By setting the tapered roller to a tapered structure, the tapered roller and the cylindrical roller can tilt synchronously when the two slide plates tilt, avoiding jamming, improving the flexibility and adaptability of the device structure, and ensuring smooth operation of the device.

[0022] 5. During cutting, one end of the label paper needs to be held manually. This not only makes it easier to rotate the cutter to apply pressure to the surface of the label paper, but also prevents the label paper from curling. At the same time, it is easier to cut the label paper into smaller pieces after cutting, making the whole operation more convenient and efficient.

[0023] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This invention has a simple structure and is easy to operate. Attached Figure Description

Detailed Implementation

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0032] A label production and printing device, such as Figures 1 to 6 As shown, the system includes a base 1, with a vertical plate 12 fixed to the top outer wall of the base 1 by bolts. A drive motor 11 is fixed to one side of the outer wall of the vertical plate 12 by bolts. The output end of the drive motor 11 is connected to a conveying roller 8 via a coupling. An elastic element is installed on the top outer wall of the base 1, including a mounting shell 9 and a sliding rod 26. The mounting shell 9 is fixed to the top outer wall of the base 1 by screws. The sliding rod 26 is slidably connected to the inner wall of a through hole at the top of the mounting shell 9. A permanent magnet 23 is fixed to the bottom of the sliding rod 26 by screws. An electromagnet 25 is fixed to the bottom inner wall of the mounting shell 9 by screws. A non-magnetic spring 24 is fixed between the top of the electromagnet 25 and the bottom of the permanent magnet 23. Support rollers are installed on the top of the two sliding rods 26. The support rollers and the conveying roller 8 work together to convey the label paper 5.

[0033] After the label paper 5 is printed, in order to prevent the label paper 5 from piling up, it needs to be conveyed. During conveying, the printed label paper 5 is placed between the support roller and the conveyor roller 8. In the initial state, the elasticity of the non-magnetic spring 24 ensures that the support roller and the conveyor roller 8 are in contact. At the same time, in order to further increase the friction between the support roller and the conveyor roller 8, the electromagnet 25 is energized to generate a repulsive force on the permanent magnet 23. The repulsive force is used to increase the pressure between the support roller and the conveyor roller 8. When the drive motor 11 drives the conveyor roller 8 to rotate and the support roller rotates in the opposite direction to the direction of the conveyor roller 8, the printed label paper 5 can be conveyed by the conveyor roller 8 and the support roller.

[0034] A printing device 6 is placed on the top outer wall of the base 1, and a roll 31 is installed inside the printing device 6, with the label paper 5 wound around the outer circumference of the roll 31.

[0035] The label printing device 6 is installed inside the roll 31 and then prints on the surface of the label paper 5. The label printing principle is to use the printing device to convert information into visual text and fix it on the label carrier. Taking thermal transfer or thermal printing as an example, thermal transfer is to heat the print head to melt the ink on the ribbon and transfer it to the label paper to form a picture; thermal printing is to heat the print head to heat the thermal coating on the thermal paper, so that it undergoes a chemical reaction to develop color and form an image. Label printing is an existing technology, and its working principle will not be described in detail here.

[0036] The top outer wall of the base 1 is fixed with a support plate 2 by bolts, and a guide roller 4 is rotatably connected between the two support plates 2;

[0037] The label paper 5 can be guided by the guide roller 4.

[0038] The support roller includes a connecting block 14 and a sliding plate 15. The connecting block 14 is fixed to the top of the sliding rod 26 by screws, and the sliding plate 15 is rotatably connected to the side wall of the connecting block 14. The outer walls of the two sliding plates 15 are respectively slidably connected to a sleeve 16 and a sleeve 29. A rotating shaft 20 is rotatably connected between the sleeve 16 and the sleeve 29. A drive motor 28 is fixed to one inner wall of the sleeve 29 by bolts, and the output end of the drive motor 28 is connected to one end of the rotating shaft 20 through a coupling. A cylindrical roller 17 and a conical roller 21 are respectively fixed to the outer wall of the rotating shaft 20, and the cylindrical roller 17 and the conical roller 21 are in contact with each other.

[0039] Initially, both slide plates 15 are horizontal. When the printed label paper 5 needs to be conveyed, the two electromagnets 25 are energized simultaneously, generating a repulsive force on the permanent magnet 23. This causes the cylindrical roller 17 to work closely with the conveyor roller 8 under the action of the repulsive force to adhere tightly to the label paper 5. When the label paper 5 needs to be conveyed, the drive motor 18 drives the cylindrical roller 17, the rotating shaft 20, and the conical roller 21 to rotate. At the same time, the drive motor 11 drives the conveyor roller 8 to rotate. The conveyor roller 8 and the cylindrical roller 17 rotate in opposite directions, so that the conveyor roller 8 and the cylindrical roller 17 convey the label paper 5 during the rotation process.

[0040] The top outer wall of the base 1 is fixed with a guide plate 22 by screws, and a movable sleeve 30 is slidably connected to the outer wall of the guide plate 22. A large gear 28 and a small gear 29 are rotatably connected to the side wall of the movable sleeve 30, and the large gear 28 and the small gear 29 mesh with each other. A rotating cutter 27 is fixed to one end of the small gear 29 by screws. A connecting frame 13 is fixed to one side of the outer wall of the first sleeve 16 and one side of the outer wall of the second sleeve 19 by screws, and the connecting frame 13 is fixedly connected to one end of the large gear 28.

[0041] When there is a need to cut the label paper 5 during the conveying process, in order to effectively improve the cutting efficiency, the magnetic pole direction of one of the electromagnets 25 inside the mounting shell 9 relative to its corresponding permanent magnet 23 is changed, so that the electromagnet 25 generates an attractive force on its corresponding permanent magnet 23, while the other electromagnet 25 maintains a repulsive force on its corresponding permanent magnet 23. At this time, the two slide plates 15 will tilt under the combined action of repulsive and attractive forces. By setting the conical roller 21 to a conical structure, the conical roller 21 and the cylindrical roller 17 can... To avoid jamming, the two slide plates 15 tilt synchronously. During the tilting process, the two slide plates 15 synchronously drive the connecting frame 13 to tilt. When the connecting frame 13 tilts, it drives the large gear 28 to rotate along the moving sleeve 30. During the rotation of the large gear 28, it drives the small gear 29 to rotate, thereby causing the rotary cutter 27 to rotate synchronously. Since the outer diameter of the large gear 28 is larger than the outer diameter of the small gear 29, the small gear 29 can rotate a larger angle when the large gear 28 rotates a smaller angle, ensuring that the rotary cutter 27 rotates at a larger angle to cut the label paper 5.

[0042] During cutting, one end of the label paper 5 needs to be held manually to facilitate the rotation of the cutter 27 to apply pressure to the surface of the label paper 5 for cutting. Holding one end of the label paper 5 manually can also prevent the label paper 5 from curling and make it easier to collect the label paper 5 after cutting.

[0043] The top outer wall of the base 1 is fixed with a bracket 3 by bolts, and the top inner wall of the bracket 3 is fixed with a vision camera 7.

[0044] After the label paper 5 is printed by the printing device 6, in order to ensure the accuracy of the cutting length of the label paper 5, the vision camera 7 can identify the label imprint on the label paper 5. After the vision camera 7 identifies the label imprint on the label paper 5, it will send a signal back so that the drive motor 11 and the drive motor 218 can stop feeding the label paper 5.

[0045] The controller 10 is fixed to the top outer wall of the base 1 by bolts;

[0046] The controller 10 is used to control the operation of the entire device. It receives the signal fed back by the vision camera 7 and controls the start and stop of the drive motor 11 and drive motor 28 according to the signal to adjust the feeding of the label paper 5. At the same time, it controls the energization state and magnetic pole direction of the electromagnet 25 to adjust the pressure of the support roller on the conveying roller 8 and control the cutting action of the rotary cutter 27.

[0047] Working principle: A roll 31 with label paper 5 wound on it is placed inside the printing device 6. The printing device 6 converts the information into a visual text and fixes it onto the label paper 5 to achieve label printing. The label paper 5 is subsequently conveyed under the guidance of the guide roller 4. In the initial state, the elasticity of the non-magnetic spring 24 ensures that the support roller and the conveyor roller 8 remain in contact. To increase the friction between the two, the electromagnet 25 is energized, causing it to generate a repulsive force on the permanent magnet 23, thereby increasing the pressure of the support roller on the conveyor roller 8. When it is necessary to convey the printed label paper 5, the drive motor 218 drives the cylindrical roller 17, the rotating shaft 20 and the conical roller 21 to rotate, and the drive motor 11 drives the conveyor roller 8 to rotate in opposite directions. Thus, the label paper 5 is conveyed by the conveyor roller 8 and the cylindrical roller 17. When there is a cutting requirement, the magnetic field of one of the electromagnets 25 inside the mounting shell 9 relative to its corresponding permanent magnet 23 is changed. The polar direction generates an attractive force, while another electromagnet 25 maintains a repulsive force. Under the combined action of the repulsive and attractive forces, the two slide plates 15 tilt, causing the conical roller 21 and the cylindrical roller 17 to tilt synchronously. The two slide plates 15 drive the connecting frame 13 to tilt, and the connecting frame 13 drives the large gear 28 to rotate along the moving sleeve 30. The large gear 28 drives the small gear 29 to rotate, thereby causing the rotating cutter 27 to rotate at a large angle to cut the label paper 5. During cutting, the operator holds one end of the label paper 5 to facilitate the application of pressure by the rotating cutter 27, while preventing the label paper 5 from curling and facilitating the unloading after cutting. After the label paper 5 is printed by the printing device 6, the visual camera 7 identifies the label imprint on the label paper 5. When the visual camera 7 identifies the label imprint, it feeds the signal back to the controller 10. The controller 10 controls the drive motor 11 and drive motor 28 to stop feeding the label paper 5 and then starts the cutting operation.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
