[0045] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0046] In the prior art, when a printer is printing a document, the ribbon used for printing may break due to friction from the printing components during the printing process.

[0047] The object to be printed (also known as the printable part) can refer to objects such as wire tubes, leather, metal plates or plastic plates, which need to have labels or patterns printed on their surfaces. In this embodiment of the application, wire tubes are used as the object to be printed for illustrative purposes.

[0048] To resolve the above technical issues, please refer to Figure 1-3This application provides a printable component, including a host 100, a transmission component 200, and a printing component 300.

[0049] The main unit 100 is the core component of the printer, containing key components such as the printhead, ink / toner cartridge, and transmission system. The main unit forms the main structure of the printer, supporting all other components. It provides a stable platform, ensuring the stability and accuracy of each component during printing. The main unit 100 has a printing slot 100a for the passage of the printable material. The printing slot 100a has an inlet end 100b and an outlet end 100c for inputting and outputting the printable material, respectively. Through an internal transmission system (such as rollers or belts), the printable material can be automatically fed in from the inlet end 100b and output from the outlet end 100c after printing.

[0050] The conveying component 200 is mounted on the host 100. The conveying component 200 includes a conveying roller 210 and a floating roller 220. A conveying channel 200a is formed between the conveying roller 210 and the floating roller 220. The conveying channel 200a extends along the first direction XX. The conveying roller 210 and the floating roller 220 drive the wire tube to be conveyed along the first direction XX.

[0051] Please see Figure 4 The printing component 300 is also mounted on the host 100. The printing component 300 includes a printing roller 310 and a printable part 320. A printing channel 300a is formed between the printing roller 310 and the printable part 320. The printing channel 300a extends along the second direction YY. The printing roller 310 and the printable part 320 drive the wire tube to be transported along the second direction YY. When a printing command is received, the printable part 320 will spray ink or toner onto the printable part 320 according to the preset pattern or text information to complete the printing task.

[0052] Through the coordinated operation of the conveying component 200 and the printing component 300, the wire marking tube comes into contact with the conveying roller 210, the floating roller 220, the printing roller 310 and the printed part 320 when passing through the conveying channel 200a and the printing channel 300a, thereby realizing the continuous conveying and efficient printing of the part to be printed 320.

[0053] In this embodiment, the inner wall of the conveying channel 200a and the inner wall of the printing channel 300a form part of the inner wall of the printing groove 100a. The side of the printed part 320 adjacent to the printing channel 300a faces the conveying channel 200a and forms a printing surface for ribbon contact.

[0054] The main function of the ribbon is to transfer toner from the ribbon to a medium (such as paper or plastic) under heat, thereby producing a durable and clear printing effect. In the heat transfer process, the ribbon acts as a medium between the ink and resin. Through the heating and pressure of the print head 323, the ink melts and is transferred to the workpiece 320 to form the desired image, text, or barcode.

[0055] The ribbon can be a resin ribbon, a wax-resin mixture ribbon, a wax-based ribbon, or a ribbon made of other materials in the existing technology. These ribbons are prone to breakage when subjected to prolonged or forceful abrasion, which affects printing.

[0056] Generally, the conveyor assembly 200 is closer to the inlet end 100b than the printing assembly 300. That is, the wire tube moves to the printing assembly 300 through the conveyor assembly 200. When the first direction XX and the second direction YY are set at an angle, the wire tube moving along the first direction XX will move along the second direction YY when it enters the printing channel 300a, that is, it changes direction. In this way, the contact area between the wire tube and the ribbon can be reduced. The pressure between the ribbon that is not in contact with the wire tube and the printing surface is relatively reduced, that is, the friction is also relatively reduced. This makes it difficult for the ribbon to rub against the printed part 320, which can protect the ribbon to a certain extent and reduce the probability of ribbon breakage.

[0057] In this embodiment, the printing surface faces the conveying channel 200a. Thus, the opening on the side of the printing channel 300a closest to the conveying channel 200a is larger, reducing the risk of the wire tube getting stuck or damaged during the feeding process. This makes it easier for the wire tube to enter the printing channel 300a, improving the smoothness and reliability of the printing operation.

[0058] It should be understood that the first direction XX and the second direction YY are both directions within a plane, specifically directions on a horizontal plane. Taking the printer's usage state as a reference, the printer has a front side close to the user and a rear side opposite to the front side. Therefore, the first direction XX can be a direction that forms an angle with the front and rear directions. In this embodiment of the application, no specific restrictions are placed on the first direction XX.

[0059] In one embodiment of this application, please refer to Figure 3-4 The outer diameter of the conveying roller 210 is smaller than the outer diameter of the printing roller 310, which makes it easier to set the extension direction of the conveying channel 200a at an angle to the extension direction of the printing channel 300a.

[0060] In addition, because the outer diameter of the conveyor roller 210 is small, it occupies relatively little space, which makes the internal structure of the printer more compact and conducive to the miniaturization and lightweight design of the printer.

[0061] In one embodiment of this application, please refer to Figure 3-5 The conveying roller 210 and the printing roller 310 are located on the same side of the printing tank 100a. The conveying roller 210 has a first projection on the first plane, and the printing roller 310 has a second projection on the first plane. Both the first projection and the second projection are tangent to the first straight line. The first straight line and the first projection have a first intersection point M, and the first straight line and the second projection have a second intersection point N. The first plane is perpendicular to the axis of the conveying roller 210 and the axis of the printing roller 310, and both the first intersection point M and the second intersection point N are located near the printing tank 100a.

[0062] Generally, the host 100 has a front end facing the user and a rear end opposite to the front end. That is, the conveying roller 210 and the printing roller 310 can be located on the front side of the printing tank 100a or on the rear side of the printing tank 100a. There is no limitation on this. In this embodiment, the conveying roller 210 and the printing roller 310 can be located on the front side of the printing tank 100a for illustrative purposes.

[0063] Since the first straight line is the common tangent of the first projection and the second projection, and the wire tube is also in contact with the conveying roller 210 and the printing roller 310, the first straight line is parallel to the wire tube located between the printing channel 300a and the conveying channel 200a.

[0064] Please continue reading. Figure 5 Along the front-back direction, the distance between the first intersection point M and the second intersection point N is h, which ranges from 1cm to 5cm. Specifically, it can be 1cm, 3cm, 5cm, or any two of the above values. Therefore, by keeping h within the above range, not only can the contact area between the wire tube and the ribbon be appropriate, and the friction between the two be appropriate, thus reducing the friction on the ribbon to a certain extent, but it can also ensure that the bending angle of the wire tube within the printing channel 300a is appropriate, thereby ensuring the smoothness of the wire tube's movement in the printing slot 100a.

[0065] For further information, please return and refer to [link / reference]. Figure 4 The printing surface and the first straight line are set at a preset angle, α, which is in the range of 10° to 70°. Specifically, it can be 10°, 20°, 30°, 50°, 70°, or any two of the above values. By keeping α within the above range, the contact area between the wire tube and the ribbon can be ensured to be appropriate, and the friction between the two can be ensured to be appropriate. This can reduce the probability of ribbon breakage caused by the ribbon rubbing against the printed part 320. At the same time, it can also ensure that the bending angle of the wire tube in the printing channel 300a is appropriate, thereby ensuring the smooth movement of the wire tube in the printing slot 100a.

[0066] Furthermore, in one embodiment of this application, the floating roller 220 is movably connected to the host 100 to adjust the horizontal distance between the conveying roller 210 and the floating roller 220, and the printed part 320 is movably connected to the host 100 to adjust the horizontal distance between the printing roller 310 and the printed part 320.

[0067] By adjusting the horizontal distance between the floating rubber roller 220 and the conveying rubber roller 210, as well as the horizontal distance between the printing rubber roller 310 and the printed part 320, the printer can adapt to wire tubes of different diameters within a certain range. It can also clamp the wire tubes to ensure that they move along a preset trajectory. Furthermore, it is convenient to remove wire tubes that have only been partially printed.

[0068] In specific movable connection methods, an eccentric wheel can be used as an adjustment element. By rotating the eccentric wheel, the horizontal distance between the floating roller 220 and the conveying roller 210, as well as the horizontal distance between the printing roller 310 and the printed part 320, can be changed. Alternatively, the floating roller 220 and the printed part 320 can be moved by a pneumatic or hydraulic system to adjust the horizontal distance. Or, a transmission component, such as a gear or drive shaft, can be used to cooperate with the cover plate of the printing slot 100a. When the cover plate is closed on the host 100, the floating roller 220 is close to the conveying roller 210, and the printed part 320 is close to the printing roller 310. When the cover plate is open relative to the host 100, the floating roller 220 is away from the conveying roller 210, and the printed part 320 is away from the printing roller 310.

[0069] It is understandable that in some embodiments, the conveying roller 210 and the printing roller 310 may also be movable relative to the host 100, thereby adjusting the size of the conveying channel 200a and the printing channel 300a accordingly.

[0070] The specific activity connection method can be set according to the actual situation, and will not be explained in detail here.

[0071] In one embodiment of this application, please refer back to the previous section. Figure 3 Combination Figure 6-7 The printable part 320 has a first protrusion 321 protruding from the print surface. The first protrusion 321 is used to press against the ribbon. The design of the first protrusion 321 is such that the ribbon does not directly contact the entire plane of the print surface during the printing process, but a portion of the ribbon can contact the first protrusion 321. In this way, the ribbon adjacent to the first protrusion 321 is difficult to contact the print surface. This reduces the actual contact area between the ribbon and the print surface, thereby reducing frictional resistance. Reduced frictional resistance helps to reduce ribbon wear, extend its service life, and reduce energy consumption during the printing process.

[0072] Furthermore, in one embodiment, please continue to refer to... Figure 3The first protrusion 321 is located at one end of the printing channel 300a adjacent to the conveying channel 200a.

[0073] Since the printing surface faces the conveyor channel 200a, the opening on the side of the printing channel 300a close to the conveyor channel 200a is larger. Therefore, there is enough space at the end of the printing channel 300a adjacent to the conveyor channel 200a to accommodate the first boss 321, and the protruding first boss 321 will not contact the wire tube, ensuring the smoothness of the wire tube.

[0074] The first boss 321 and the printed part 320 can be integrally formed to increase the overall structural stability, or the first boss 321 and the printed part 320 can be connected by bolts or screws. The specific configuration can be set according to the actual situation, and no restrictions are imposed here.

[0075] Please refer to another embodiment of this application. Figure 6 The side of the first boss 321 facing away from the printed part 320 is a protruding arc-shaped surface. The arc-shaped surface design reduces the contact area between the carbon ribbon and the first boss 321, thereby reducing friction and wear and extending the service life of the carbon ribbon.

[0076] In addition, since the first protrusion 321 is an arc-shaped surface that contacts the ribbon, it can ensure the smooth movement of the ribbon, thereby ensuring that the material can be stably thermally transferred to the surface of the wire tube and ensuring printing quality.

[0077] When printing with a ribbon vial, it also needs to be moved so that pattern markings can be formed on the surface of the vial. That is, the ribbon has an inlet end and an outlet end within the printing channel 300a. Therefore, in one embodiment of this application, please refer to the following. Figure 7 In order to ensure the smooth movement of the wire tube, the first boss 321 has a guide surface 321a. The guide surface 321a is set facing the tape inlet end. From the tape inlet end to the tape outlet end, the distance between the guide surface 321a and the printing surface gradually increases.

[0078] Thus, the design of the guide surface 321a allows the ribbon to transition smoothly as it moves from the inlet end to the outlet end. The gradually increasing distance between the guide surface 321a and the printing surface ensures that the ribbon will not wrinkle or shift due to sudden changes in direction or excessive pressure within the printing channel 300a, thereby guaranteeing print quality.

[0079] Furthermore, as the ribbon moves from the feed end to the output end, the distance between the guide surface 321a and the printing surface gradually increases. This helps to reduce the tension of the ribbon during the printing process. Reducing tension can reduce the risk of ribbon wear and breakage, and extend the service life of the ribbon.

[0080] The guide surface 321a can be an outwardly protruding arc surface or an inclined surface. In order to further reduce the friction between the first boss 321 and the carbon ribbon, the guide surface 321a can smoothly transition with other surfaces on the first boss 321.

[0081] In the implementation of this application, please refer to Figure 6-7 The printout 320 includes a print base 322 and a print head 323. The print base 322 is mounted on the printer, and the print head 323 protrudes from the print base 322 on the side facing the print channel 300a. The side of the print head 323 away from the print base 322 forms a printing surface for contacting the ribbon.

[0082] The print base 322 is the support structure for the print head 323. It is installed inside the printer and provides a stable foundation so that the print head 323 can be accurately positioned on one side of the print channel 300a.

[0083] The printhead 323 is a key component for performing the printing operation. It transfers images or text onto the printable part 320 by contacting the ribbon. It is important to understand that the printhead 323 is generally a TPH (Thermal Print Head), which has relatively sharp edges. The first boss 321 protrudes at a height greater than that of the printhead 323, which effectively prevents the sharp edge of the TPH-heated printhead 323 from directly contacting the ribbon. This ensures that the ribbon can pass smoothly during the printing process without being cut by the sharp edge of the TPH-heated printhead 323, thereby improving the continuity and stability of the printing.

[0084] Furthermore, the printing surface is provided with heated printing lines 324, which are used to contact the ribbon. The heated printing lines 324 are a row of heating elements in the thermal printhead 323, which are usually composed of heating resistors with the same resistance and arranged closely. Under normal circumstances, they are used to generate high temperature by passing current, thereby initiating a chemical reaction on the dielectric coating and showing color. Specifically, in the embodiment of this application, the heated printing lines 324 need to contact the ribbon to achieve heating and transfer of the ribbon.

[0085] In some embodiments, the difference between the protrusion height of the first boss 321 and the protrusion height of the print head 323 is d1, and d1 is in the range of 0.5mm-2mm. Specifically, d1 can be 0.5mm, 1mm, 2mm, or any two of the above values. By ensuring that d1 is within the above range, the difference between the protrusion height of the first boss 321 and the protrusion height of the print head 323 is appropriate. This ensures that the ribbon is not easily cut by the print head 323, and that the inclined ribbon can contact the heated printing line 324, thus guaranteeing the printing effect.

[0086] Please see Figure 6-7 In another embodiment of this application, the print head 320 further includes a second boss 325. The second boss 325 protrudes from the side of the print head 322 facing the print channel 300a. The second boss 325 and the first boss 321 are distributed at intervals on both sides of the print head 323 along the extension direction of the print channel 300a. The protrusion height of the second boss 325 is less than the protrusion height of the print head 323.

[0087] The second protrusion 325 can also support the ribbon, reducing the probability of the printhead 323 cutting the ribbon. Since the protrusion height of the second protrusion 325 is less than that of the printhead 323, it ensures that the ribbon can fit tightly against the printhead 323 during printing, avoiding damage to the ribbon due to excessive pressure. On the other hand, the support of the ribbon by the second protrusion 325 can further ensure the stability and safety of the ribbon in the printing channel 300a, thus further guaranteeing the printing effect.

[0088] Based on the previous implementation, please continue to refer to... Figure 6-7 The side of the second protrusion 325 facing away from the printed part 320 is a protruding arc-shaped surface. The arc-shaped surface design makes the contact between the second protrusion 325 and the ribbon softer, reducing wear caused by direct contact. The arc-shaped surface can disperse the pressure of the ribbon when it passes through, avoid excessive local wear, and help extend the service life of the ribbon.

[0089] It is important to understand that when the first protrusion 321 presses against the ribbon, causing the ribbon to tilt relative to the printing surface, if the difference between the protrusion height of the second protrusion 325 and the protrusion height of the printhead 323 is too large, the second protrusion 325 may have difficulty supporting the ribbon. Therefore, in this application, the difference between the protrusion height of the second protrusion 325 and the protrusion height of the printhead 323 is d2. The value of d2 is in the range of 0.5mm-2mm, specifically 0.5mm, 1mm, 2mm, or any two of the above values. By ensuring that d2 is within the above range, the difference between the protrusion height of the second protrusion 325 and the protrusion height of the printhead 323 is appropriate, which can both prevent the ribbon from being cut by the printhead 323 and ensure that the tilted ribbon contacts the second protrusion 325, thus guaranteeing the printing effect of the ribbon.

[0090] In one embodiment of this application, please refer back to the previous section. Figure 1-2 The printer also includes a ribbon cartridge 400, which is located on the main unit 100. The main function of the ribbon cartridge 400 is to hold and protect the ribbon, ensuring that the ribbon can be supplied smoothly and continuously to the print head 323 during the printing process.

[0091] The ribbon cartridge 400 forms a placement slot 400a with an opening facing the printing channel 300a, which allows the ribbon to enter the printing area directly and quickly.

[0092] The printed part 320 is at least partially located in the placement slot 400a, that is, the printed part 320 can be partially located in the placement slot 400a or it can be completely located in the placement slot 400a. In this way, the printed part 320 does not occupy additional space in the host 100, making the entire host 100 structure compact and miniaturized.
