Description

Technical Field

[0001] This utility model relates to the field of carbon ribbon technology, specifically to carbon ribbons for printing in packaging machines. Background Technology

[0002] Packaging machine printing ribbon, or simply ribbon, is a consumable for thermal transfer printers. It uses heat to transfer ink from the ribbon to the surface of the packaging material, forming a durable and clear mark, such as production date, batch number, barcode, etc.

[0003] Existing packaging machines cannot adjust the spacing between the two ribbon rollers during use. The current packaging machine ribbon module adopts a fixed roller spacing design, which has insufficient size compatibility. The ribbon guide roller spacing is limited to a single specification, which cannot adapt to small labels with a width of <20mm or large-format packaging materials with a width of >50mm, resulting in printing area misalignment or ribbon breakage.

[0004] Therefore, we propose printing carbon ribbons for packaging machines. Utility Model Content

[0005] The purpose of this utility model is to provide a printing ribbon for a packaging machine to solve the problems mentioned in the background art. To achieve the above purpose, this utility model provides the following technical solution: A printing ribbon for a packaging machine includes a mounting plate. One side of the mounting plate is integrally formed with a second mounting groove. A cavity is opened inside the mounting plate. A lead screw is installed inside the cavity through a bearing. A threaded slider is fitted on the outside of the lead screw through thread engagement. One side of the threaded slider slides out of the cavity. One end of the threaded slider is fixedly connected to one side of a first mounting groove. A hidden groove is opened on one side of the mounting plate. A rotating seat is rotatably installed inside the hidden groove. The output end of the rotating seat extends into the cavity and is fixedly connected to one end of the lead screw. A ribbon roller is installed inside the first mounting groove and the second mounting groove respectively. A ribbon body is sleeved between the two ribbon rollers. A limiting component is installed on one side of the first mounting groove and the second mounting groove respectively.

[0006] Preferably, a pull ring is installed on one side of the mounting plate via a rotating shaft, and a circular limiting plate is fixedly sleeved on the outer side of each end of the two carbon belt rollers.

[0007] Preferably, the limiting component includes a first limiting clamp and a second limiting clamp, and the second limiting clamp is rotatably connected to the first limiting clamp.

[0008] Preferably, a limiting groove is provided on one side of the first limiting clamp and the second limiting clamp, and a magnet is fixed to one end of the first limiting clamp and an iron sheet is fixed to one end of the second limiting clamp.

[0009] Preferably, the ribbon body includes a substrate layer, and one side of the substrate layer is coated with an ink layer, and the other side of the substrate layer is coated with a back coating layer.

[0010] Preferably, a compression spring is installed inside the first mounting groove and the second mounting groove, and the compression spring is used in conjunction with the carbon belt roller.

[0011] Compared with the prior art, the present invention provides a printing ribbon for packaging machines, which has the following beneficial effects:

[0012] By rotating the rotating base using a tool, the rotating base will drive the lead screw to rotate. The rotation of the lead screw will then drive the threaded slider to slide along the installation direction of the lead screw. The sliding of the threaded slider will cause the first mounting groove to slide on one side of the mounting plate. By controlling the sliding of the first mounting groove on one side of the mounting plate, the distance between the first mounting groove and the second mounting groove can be adjusted. By adjusting the distance between the first mounting groove and the second mounting groove, the printing range of the ribbon body can be changed, avoiding offset of the printing area or ribbon breakage.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1: A second mounting groove 10 is integrally formed on one side of the mounting plate 1. A cavity 5 is formed inside the mounting plate 1. A lead screw 4 is installed inside the cavity 5 through a bearing. A threaded slider 6 is fitted on the outside of the lead screw 4 through thread engagement. One side of the threaded slider 6 extends slidably out of the cavity 5. One end of the threaded slider 6 is fixedly connected to one side of the first mounting groove 7. A hidden groove 12 is formed on one side of the mounting plate 1. A rotating seat 13 is rotatably installed inside the hidden groove 12. The output end of the rotating seat 13 extends into the cavity 5 and is fixedly connected to one end of the lead screw 4. A carbon ribbon roller 11 is installed inside the first mounting groove 7 and the second mounting groove 10 respectively. A carbon ribbon body 8 is fitted between the two carbon ribbon rollers 11. A limiting component 9 is installed on one side of the first mounting groove 7 and the second mounting groove 10 respectively.

[0020] Specifically, such as Figure 1 and Figure 4 As shown, a hidden groove 12 is provided on one side of the mounting plate 1, and a rotating seat 13 is rotatably installed inside the hidden groove 12. By setting the hidden groove 12 to hide the rotating seat 13, it can be ensured that the ribbon can be properly installed into the printer. Then, the rotating seat 13 is rotated using a tool. Since the output end of the rotating seat 13 extends into the cavity 5 and is fixedly connected to one end of the lead screw 4, the rotation of the rotating seat 13 will drive the lead screw 4 to rotate. Since a threaded slider 6 is provided on the outside of the lead screw 4 through threaded engagement, the rotation of the lead screw 4 will drive the threaded slider 6 to slide along the installation direction of the lead screw 4. Since one side of the threaded slider 6 slides out of the cavity 5, The first mounting plate 10 is fixedly connected to one end of the first mounting groove 7. Therefore, the first mounting groove 7 can be moved to slide on one side of the mounting plate 1 by sliding the threaded slider 6. Since the second mounting groove 10 is fixedly installed on one side of the mounting plate 1, the distance between the first mounting groove 7 and the second mounting groove 10 can be adjusted by controlling the sliding of the first mounting groove 7 on one side of the mounting plate 1. Since a ribbon roller 11 is installed inside the first mounting groove 7 and the second mounting groove 10 respectively, and the ribbon body 8 is sleeved between the two ribbon rollers 11, the printing range of the ribbon body 8 can be changed by adjusting the distance between the first mounting groove 7 and the second mounting groove 10, so as to avoid the printing area from shifting or the ribbon from breaking.

[0021] Example 2: A pull ring 3 is installed on one side of the mounting plate 1 via a rotating shaft, and a circular limiting plate is fixedly sleeved on the outer side of each end of the two carbon ribbon rollers 11. The limiting assembly 9 includes a first limiting clamp 901 and a second limiting clamp 905. The second limiting clamp 905 is rotatably connected to the first limiting clamp 901. A limiting groove 904 is opened on one side of the first limiting clamp 901 and the second limiting clamp 905, and a magnet 902 is fixed at one end of the first limiting clamp 901. An iron piece 903 is fixed at one end of the second limiting clamp 905. The carbon ribbon body 8 includes a substrate layer 801, and an ink layer 802 is coated on one side of the substrate layer 801. A back coating layer 803 is coated on the other side of the substrate layer 801. A compression spring 2 is installed inside the first mounting groove 7 and the second mounting groove 10, and the compression spring 2 is used in conjunction with the carbon ribbon roller 11.

[0022] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, by opening the second limiting clamp 905, the iron sheet 903 is separated from the magnet 902. Then, the carbon ribbon roller 11 is installed into the first mounting groove 7 or the second mounting groove 10. The compression spring 2 is installed inside the first mounting groove 7 or the second mounting groove 10, so that the compression spring 2 abuts against the circular limiting plate at one end of the carbon ribbon roller 11. Then, the circular limiting plate at the other end of the carbon ribbon roller 11 is inserted into the limiting groove 904 opened on one side of the first limiting clamp 901. Finally, the second limiting clamp 905 is closed, so that the upper half of the circular limiting plate at one end of the carbon ribbon roller 11 is inserted into the limiting groove 904 opened on one side of the second limiting clamp 905. Inside the limiting groove 904, the magnet 902 is then magnetically connected to the iron sheet 903, thereby limiting the circular limiting plate at one end of the ribbon roller 11 between the first limiting clamp 901 and the second limiting clamp 905. The substrate layer 801 is made of polyester film, polyimide, etc., with a thickness of 4.5~6um, and has the characteristics of high temperature resistance and tensile strength. The ink layer 802 is made of wax-based, mixed-based, or resin-based ink, which determines the wear resistance and chemical resistance of the print. The back coating layer 803 is made of silicone layer or special coating, which reduces the wear of the print head and improves the stability of the ribbon operation.

[0023] Working principle: In use, by opening the second limiting clamp 905, the iron piece 903 is separated from the magnet 902. Then, the carbon ribbon roller 11 is installed into the first mounting groove 7 or the second mounting groove 10. The compression spring 2 is installed inside the first mounting groove 7 or the second mounting groove 10, so that the compression spring 2 abuts against the circular limiting plate at one end of the carbon ribbon roller 11. Then, the circular limiting plate at the other end of the carbon ribbon roller 11 is inserted into the limiting groove 904 opened on one side of the first limiting clamp 901. Then, the second limiting clamp 905 is closed, so that the upper half of the circular limiting plate at one end of the carbon ribbon roller 11 is inserted into the limiting groove 904 opened on one side of the second limiting clamp 905. Then, the magnet 902 is magnetically connected to the iron piece 903, thereby limiting the circular limiting plate at one end of the carbon ribbon roller 11 between the first limiting clamp 901 and the second limiting clamp 905. The rotating seat 13 can be rotated using a tool. When the rotating seat 13 rotates, it drives the lead screw 4 to rotate. When the lead screw 4 rotates, it drives the threaded slider 6 to slide along the installation direction of the lead screw 4. The sliding of the threaded slider 6 can drive the first mounting groove 7 to slide on one side of the mounting plate 1. Since the second mounting groove 10 is fixedly installed on one side of the mounting plate 1, the distance between the first mounting groove 7 and the second mounting groove 10 can be adjusted by controlling the sliding of the first mounting groove 7 on one side of the mounting plate 1. Since a ribbon roller 11 is installed inside the first mounting groove 7 and the second mounting groove 10 respectively, and the ribbon body 8 is sleeved between the two ribbon rollers 11, the printing range of the ribbon body 8 can be changed by adjusting the distance between the first mounting groove 7 and the second mounting groove 10, so as to avoid the printing area from shifting or the ribbon from breaking. Then the ribbon can be installed into the printer for use.

[0024] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
