Abstract
Description
Technical Field
[0001] This utility model relates to the field of box labeling machine technology, and in particular to a carbon ribbon positioning component and a box labeling machine. Background Technology
[0002] Carton label printers are essential equipment in logistics and warehousing management, widely used for printing and affixing labels to product packaging. Thermal transfer ribbon, a key consumable in thermal transfer printing, works by transferring ink from the ribbon to the label surface via a thermal printhead, creating clear identification information. Currently, the ribbon transport system of carton label printers typically uses a motor to drive a fixed ribbon shaft, with the ribbon wound around the shaft and rotating synchronously with it.
[0003] In current box label printer designs, the fit precision between the ribbon fixing shaft and the ribbon's inner diameter directly affects print quality. In actual production, the outer diameter of the ribbon fixing shaft may have tolerances, and the inner diameter of ribbons from different batches may also vary slightly. When a gap appears between the inner wall of the ribbon and the outer wall of the fixing shaft, the ribbon may not rotate in perfect sync with the shaft during the motor-driven rotation, causing relative slippage on the shaft surface. This slippage results in a misalignment between the ribbon's feed position and the printhead's working rhythm, ultimately manifesting as offset or misalignment of the printed content on the box label. Utility Model Content
[0004] The purpose of this invention is to provide a ribbon positioning component and a box label printer, which effectively reduces the slippage of the ribbon relative to the ribbon fixing shaft and alleviates the offset or misalignment phenomenon that occurs during the box label printing process.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0032] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0033] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.
[0034] The first aspect of this utility model provides a carbon ribbon positioning component, such as... Figures 1 to 5 As shown, it includes a spacer 1, a spring assembly 2, and a base plate 3;
[0035] Spacer 1 is used to be fitted onto the outside of carbon ribbon fixing shaft 5;
[0036] The spring assembly 2 is connected to the spacer 1 and protrudes from the top surface of the spacer 1. The spring assembly 2 is used to abut against the inner wall of the carbon ribbon 4 and engage with the carbon ribbon fixing shaft 5 so that the carbon ribbon 4 rotates with the carbon ribbon fixing shaft 5.
[0037] The base plate 3 is sleeved on the outside of the spring assembly 2 and overlaps the top surface of the spacer 1. The base plate 3 is used to support the bottom surface of the carbon belt 4.
[0038] When using the carbon ribbon positioning component provided by this utility model, such as Figure 4 As shown, the spacer 1 can be fitted onto the outside of the carbon ribbon fixing shaft 5; as Figure 5As shown, the carbon ribbon 4 is sleeved on the outside of the spring assembly 2 and mounted on the base plate 3. When the carbon ribbon fixing shaft 5 rotates, the spring assembly 2 abuts against the inner wall of the carbon ribbon 4 and engages with the carbon ribbon fixing shaft 5, which allows the carbon ribbon 4 to rotate with the carbon ribbon fixing shaft 5. This effectively reduces the slippage of the carbon ribbon 4 relative to the carbon ribbon fixing shaft 5 and alleviates the offset or misalignment that occurs during the printing of the box label.
[0039] In an optional embodiment, the spring assembly 2 includes a plurality of springs 21 connected to the spacer 1, each spring 21 extending into the spacer 1 and spaced circumferentially along the inner wall of the spacer 1.
[0040] In the above embodiments, the spring assembly 2 includes multiple springs 21. The multiple springs 21 can ensure that the spring assembly 2 is more stably engaged with the carbon ribbon fixing shaft 5, and at the same time, can also ensure the firmness of the contact between the springs 21 and the inner wall of the carbon ribbon 4, so that the carbon ribbon 4 can continuously follow the rotation of the carbon ribbon fixing shaft 5.
[0041] In addition, in the above embodiment, each spring piece 21 extends into the spacer 1, which makes it easier to connect the spring piece 21 to the spacer 1. For example, the spring piece 21 can be welded to the spacer 1, and the welding point can be located at the position where the spring piece 21 enters the spacer 1, which facilitates the connection between the spacer 1 and the spring piece 21.
[0042] In alternative implementations, such as Figure 6 As shown, the portion of each spring piece 21 that extends out of the top surface of the spacer 1 is a protrusion 211. The protrusion 211 extends gradually towards the axis of the spacer 1 in a direction that gradually moves away from the spacer 1 and then gradually moves away from the axis of the spacer 1.
[0043] In the above embodiments, on the one hand, since the portion of the protrusion 211 close to the axis of the spacer 1 can be more firmly locked onto the carbon ribbon fixing shaft 5, it ensures that the carbon ribbon fixing shaft 5 can stably drive the spring assembly 2 and the spacer 1 to rotate during rotation; on the other hand, the portion of the protrusion 211 away from the axis of the spacer 1 can more tightly abut against the inner wall of the carbon ribbon 4, increasing the friction between the two, ensuring that the carbon ribbon 4 can follow the rotation of the spring assembly 2 and the spacer 1 during rotation, thereby realizing that the carbon ribbon 4 rotates synchronously with the carbon ribbon fixing shaft 5.
[0044] The protrusion 211 of the aforementioned spring piece 21 is bent, which can increase the friction between the spring piece 21 and the inner wall of the carbon ribbon 4 through its own elasticity, thereby effectively reducing the phenomenon of the carbon ribbon 4 slipping during rotation.
[0045] Of course, in other alternative embodiments, the protrusion 211 may also extend along the axis parallel to the spacer 1. The diameter of the circumscribed circle corresponding to the protrusion 211 in each spring can be larger than the inner diameter of the carbon ribbon 4. After the carbon ribbon 4 is sleeved on the outside of each protrusion 211, the inner surface of the carbon ribbon 4 will press against each protrusion 211, forcing each protrusion 211 to deform in the direction close to the axis of the carbon ribbon 4, increasing the friction between the carbon ribbon 4 and the protrusion 211, so that the carbon ribbon 4 can rotate with the carbon ribbon fixing shaft 5 under the drive of the spring assembly 2.
[0046] Each of the aforementioned spring pieces 21 can be made of thin steel plate, which has good strength and can undergo a certain degree of deformation to support the carbon ribbon 4.
[0047] Specifically, the shrapnel 21 can be configured as one, two, three or even more.
[0048] In alternative implementations, such as Figure 1 As shown, the spring assembly 2 includes a first spring and a second spring, which are arranged radially opposite to each other along the spacer 1.
[0049] In the above embodiment, two spring pieces 21 are configured, and the two spring pieces 21 are arranged opposite each other along the radial direction of the spacer 1. This ensures that the two spring pieces 21 can generate two elastic forces in opposite directions on the carbon ribbon 4 along the radial direction, so that the axis of the carbon ribbon 4 can be aligned with the axis of the carbon ribbon fixing shaft 5 as much as possible, while ensuring the stable rotation of the carbon ribbon 4.
[0050] like Figure 1 As shown, the first and second springs are inserted through the spacer 1, and both the first and second springs are welded to the spacer 1.
[0051] Alternatively, spacer 1 can be made of steel pipe with an inner diameter of 25mm.
[0052] In an optional implementation, the base plate 3 is a transparent plate.
[0053] The base plate 3 can be made of acrylic sheet, glass sheet, etc.
[0054] like Figure 3 As shown, the base plate 3 can adopt a circular structure, with an inner diameter of 26mm and an outer diameter of 56mm.
[0055] It should be noted that the outer diameter of the spacer 1 is larger than the inner diameter of the base plate 3, so that the base plate 3 can be smoothly attached to the spacer 1 without falling off.
[0056] The aforementioned base plate 3 serves to support the carbon ribbon 4 and increase the support area of the carbon ribbon 4.
[0057] In alternative implementations, such as Figure 1 As shown, the carbon ribbon positioning assembly also includes an extension component 6 that protrudes radially from the bottom surface of the spacer 1.
[0058] When the ribbon positioning assembly is sleeved on the ribbon fixing shaft 5, the extended assembly 6 protrudes radially from the bottom surface of the spacer 1, which can support the spacer 1 and prevent the ribbon positioning assembly from falling into the hole between the ribbon fixing shaft 5 and the bottom support plate 7.
[0059] Specifically, such as Figure 1 As shown, the extension assembly includes a first extension portion 61 and a second extension portion 62 arranged radially opposite to each other along the spacer 1. The first extension portion 61 and the second extension portion 62 can fully support the spacer 1 and ensure the stability of the spacer 1.
[0060] The first extension portion 61 and the second extension portion 62 can be plate-shaped, and they are connected to the spacer 1 by welding or other means.
[0061] The second aspect of this utility model provides a box labeling machine, which includes the aforementioned carbon ribbon positioning component.
[0062] The carton label machine provided in the second aspect of this utility model has the carbon ribbon positioning component provided in the first aspect of this utility model, and thus has all the beneficial effects of the carbon ribbon positioning component provided in the first aspect of this utility model.
[0063] In an optional embodiment, the above-mentioned box labeling machine further includes a carbon ribbon fixing shaft 5 and a carbon ribbon 4. The carbon ribbon 4 is sleeved on the outside of the spring assembly 2 and mounted on the base plate 3. The spring assembly 2 abuts against the inner wall of the carbon ribbon 4 and is inserted into the carbon ribbon fixing shaft 5.
[0064] In the above embodiments, the spring assembly 2 and the carbon ribbon fixing shaft 5 are connected by a snap-fit connection, which can effectively ensure the circumferential position of the spring assembly 2 relative to the carbon ribbon fixing shaft 5, and drive the carbon ribbon 4 to rotate more stably.
[0065] like Figure 4 and Figure 5 As shown, the carbon ribbon fixing shaft 5 includes a top seat 51 and a plurality of connecting pieces 52 connected to the top seat 51 circumferentially. A gap is formed between any two adjacent connecting pieces 52. A spacer 1 is sleeved on the outside of each connecting piece 52. The spring assembly 2 abuts against the inner wall of the carbon ribbon 4 and is inserted into at least one gap.
[0066] In the above embodiment, the top seat 51 serves to connect each connecting piece 52. During use, the top seat 51 and each connecting piece 52 rotate together under the drive of the drive mechanism. Since the spring piece assembly 2 is inserted into at least one gap, the spring piece assembly 2 can rotate synchronously. Since the spring piece assembly 2 abuts against the inner wall of the carbon ribbon 4, the rotation of the carbon ribbon 4 can be realized simultaneously.
[0067] In alternative implementations, such as Figure 4 and Figure 5 As shown, the box labeling machine also includes a bottom support plate 7, and the carbon belt fixing shaft 5 passes through the bottom support plate 7 and has a certain gap between it and the bottom support plate 7.
[0068] In an optional implementation, the height of the carbon ribbon along its own axial direction is 40 mm.
[0069] In the existing technology, the height of the carbon ribbon 4 used in the box label machine is 70mm. In fact, printing QR code labels only occupies half of the height of the carbon ribbon 4. The carbon ribbon 4 is discarded after use, resulting in serious waste of the carbon ribbon 4. In the above embodiment, the height of the carbon ribbon is optimized to 40mm, which can effectively save costs. According to statistics, the optimization of carbon ribbon 4 can save about 100,000 yuan per year.
[0070] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
