Abstract
Description
Technical Field
[0001] This application relates to a recycling spindle of a printing apparatus and a printing apparatus, particularly a printing device that uses a ribbon for printing and a recycling spindle of the printing device. Background Technology
[0002] In most common printing devices, especially medium to large commercial printers, the ribbon recycling process is as follows: the user must first prepare an empty hollow paper tube, place the hollow paper tube onto a recycling spindle of the printing device, and attach one end of the ribbon to the hollow paper tube. When the printing device starts printing, the recycling spindle is controlled to rotate, and the ribbon will be wound around the hollow paper tube.
[0003] After a hollow paper tube is wrapped with a lot of carbon ribbon, the user will remove the paper tube with the ribbon wrapped around it and remove the ribbon from the paper tube so that the paper tube can be reused. However, in practice, after removing the paper tube with the ribbon wrapped around it, the user usually discards the ribbon and the paper tube together. Therefore, the user must prepare another hollow paper tube next time in order to continue recycling the ribbon. Utility Model Content
[0004] The technical problem to be solved by this application is to provide a recycling spindle and printing device, mainly to improve the existing printing device's recycling spindle, which requires the additional installation of a hollow paper tube so that the ribbon to be recycled can be smoothly wound onto the hollow paper tube, thus causing many inconveniences in use.

[0011] Optionally, the recycling shaft further includes a shaft structure, one end of which is used to connect to the drive module. The shaft structure passes through the body and is fixed to the body.
[0012] Optionally, the pressing member includes a pressing part and an annular wall, one side of the pressing part extends outward to form the annular wall, one end of the body has a limiting groove, and a portion of the annular wall is disposed in the limiting groove.

[0026] In the following description, if a specific drawing is indicated or shown in a particular drawing, it is only to emphasize that most of the relevant content mentioned in the following description appears in that particular drawing, but does not limit the following description to refer only to that particular drawing.
[0027] Please see Figure 1 This is a partial cross-sectional schematic diagram of the printing device of this application. The printing device 100 of this application includes a device body 1, a printhead device 2, a recycle spindle 3, a processing device 4, and a drive module (not shown in the figure). The device body 1 generally refers to the main support structure and outer casing of the printing device 100. The printhead device 2, the recycle spindle 3, and the processing device 4 are disposed in the device body 1. The device body 1 can accommodate a paper roll 200 to be printed and a ribbon (not shown in the figure). The paper roll 200 to be printed may include, for example, a substrate 201 and multiple labels 202, but is not limited thereto. The processing device 4 is electrically connected to the printhead device 2. The printhead device 2 includes a printhead module. The processing device 4 can control the printhead module to make the printhead module cooperate with the ribbon to print the labels 202. The processing device 4 is electrically connected to the drive module, which is connected to the recycle spindle 3. The processing device 4 can control the drive module to make the recycle spindle 3 rotate. The drive module may include, for example, an electric motor and related transmission components (such as gears, belts, etc.).
[0028] The other components included in the printing device 100 and the interrelationships between these components can be achieved directly using various existing common methods, and will not be elaborated here. The following description only addresses the differences between the printing device 100 of this application and the prior art.
[0029] The recycling spindle 3 is primarily used to provide a reusable ribbon for the printing device 100. One end of the recycling spindle 3 is connected to the drive module of the printing device 100. The drive module includes, for example, a motor and transmission components (such as gears, belts, etc.). The motor drives the recycling spindle 3 to rotate via the transmission components. In practice, when installing the ribbon, the user can first wind one end of the ribbon onto the recycling spindle 3. Then, once the printing device 100 starts printing, the reusable ribbon will automatically wind onto the recycling spindle 3.
[0030] Please refer to the following: Figures 2 to 7 , Figure 2 and Figure 3 These are schematic diagrams of the recycling shaft from different perspectives in this application. Figure 4 This is a partially exploded view of the recycling shaft of this application. Figure 5 This is a partially exploded view of the recycling shaft of this application. Figure 6 For the recycling of the shaft edge of this application Figure 3 A cross-sectional diagram of section line VI-VI. Figure 7 For the recycling of the shaft edge of this application Figure 2 A schematic diagram of the cross section VII-VII.
[0031] The retrieval shaft 3 includes: a connecting shaft 31, a body 32, a pressing member 33, an elastic member 34, and two movable components 35. Each movable component 35 includes a linkage member 351, a moving member 352, and a movable housing 353. The number of movable components 35 included in the retrieval shaft 3 is not limited to two. In different embodiments, the retrieval shaft 3 may include only a single movable component 35, or it may include three or more movable components 35.
[0032] One end of the connecting shaft 31 is used to connect to the drive module of the printing device. The connecting shaft 31 passes through the body 32, and the connecting shaft 31 and the body 32 are fixed to each other. Specifically, the body 32 and the connecting shaft 31 may each have a corresponding number of locking holes, and the body 32 and the connecting shaft 31 may be secured by multiple connecting shaft locking fasteners S1 (such as...). Figure 6 As shown, for example, screws) are locked together. The connecting shaft 31 and the body 32 are fixed to each other, so when the drive module of the printing device drives the connecting shaft 31 to rotate, the body 32 will rotate together with the connecting shaft 31.
[0033] The pressing member 33 is movably disposed at one end of the body 32. The pressing member 33 includes, for example, a pressing portion 331 and an annular wall 332, with the annular wall 332 extending outward from one side of the pressing portion 331. One end of the body 32 may have a limiting groove 321, and a portion of the annular wall 332 is disposed within the limiting groove 321. Through the design of the annular wall 332 and the limiting groove 321, the range of motion of the pressing member 33 can be limited, allowing it to move only approximately along an axial direction L1 when pressed by the user. In practical applications, the retrieval shaft 3 rotates around a central axis, with the axial direction L1 parallel to the central axis.
[0034] The two ends of the elastic member 34 are fixed to the body 32 and the pressing member 33, respectively. When the pressing member 33 is pressed, the elastic member 34 will be compressed and elastically deformed; when the pressing member 33 is no longer pressed, the elastic restoring force of the elastic member 34 will cause the elastic member 34 to return to the unpressed position. One end of the body 32 is recessed to form a receiving groove, which is used to receive at least a portion of the elastic member 34.
[0035] The main body 32 may have two slides 322. The two slides 322 may be formed on two generally opposite sides of the main body 32. One end of each slide 322 is a closed end, and the other end is an open end. The linkage 351 and the moving part 352 of each movable component 35 can be inserted into the slide 322 through the open end of the slide 322. Since the other end of the slide 322 is a closed end, during the assembly process, after the linkage 351 and the moving part 352 are inserted into the slide 322 through the open end of the slide 322, the linkage 351 and the moving part 352 will not leave the main body 32 through the other end of the slide 322.
[0036] The two movable components 35 may be located on two generally opposite sides of the main body 32. The placement of the movable components 35 included in the retrieval shaft 3 may vary depending on the number of movable components 35 included in the retrieval shaft 3, and is not limited to what is shown in the figure.
[0037] One end of each linkage 351 can be fixed to the pressing member 33 by means of a fastener (e.g., a screw). It should be noted that the pressing member 33 is fixed to the linkages 351 of multiple movable components 35 at the same time, and when the pressing member 33 moves relative to the body 32, the pressing member 33 can simultaneously drive the linkages 351 of each movable component 35 to move relative to the body 32.
[0038] like Figures 5 to 7As shown, the linkage 351 includes, for example, an axial structure 3511, a plurality of limiting structures 3512, and a stop structure 3513. The axial structure 3511 is, for example, a rectangular plate-like structure. The plurality of limiting structures 3512 may be formed by extending from one side of the axial structure 3511 to both outer sides of the axial structure 3511.
[0039] Each slide groove 322 may have an auxiliary limiting groove 323, which is used to accommodate the limiting structure 3512. The limiting structure 3512 and the auxiliary limiting groove 323 together restrict the range of motion of the linkage 351 in the slide groove 322. Specifically, the auxiliary limiting groove 323 may be formed in the body 32 generally along an axial direction L1, and the width of the auxiliary limiting groove 323 in the radial direction L2 is greater than the width of the slide groove 322 in the radial direction L2. The linkage 351 can move in the slide groove 322 along the axial direction L1, while the limiting structure 3512 and the auxiliary limiting groove 323 together restrict the range of motion of the linkage 351 relative to the slide groove 322 in the radial direction L2; the radial direction is perpendicular (or generally perpendicular) to the axial direction.
[0040] The stop structure 3513 is formed by extending the axial structure 3511 in the lateral direction. The linkage 351 is disposed in the slide groove 322, and the stop structure 3513 is used to divide the slide groove 322 into a partition groove 3221 (e.g., Figure 4 (As shown). The movable member 352 is disposed in the partition groove 3221, and the range of motion of the movable member 352 along the axial direction L1 is limited by the slide groove 322 and the stop structure 3513.
[0041] like Figure 5 As shown, the axial structure 3511 of each linkage 351 may include multiple first conversion structures 3514. Each first conversion structure 3514 is, for example, an oblique through hole, which is disposed through the axial structure 3511. The end of each oblique through hole near the pressing member 33 is defined as the front end, and the other end is defined as the rear end. The distance between the front end and the body 32 is less than the distance between the rear end and the body 32. That is, as shown... Figure 6 As shown in the cross-sectional view of the recycling shaft 3, the pressing element 33 is located at... Figure 6 On the left side of the middle, and the tilting direction of each oblique perforation is due to... Figure 6 It tilts from the upper right to the lower left.
[0042] like Figure 5 As shown, each movable component 352 can be generally a rectangular plate structure, and the overall length of the movable component 352 along the axial direction L1 is less than the length of the axial structure 3511 of the linkage 351. The movable component 352 can be disposed in the partition groove 3221 (e.g., Figure 4As shown in the diagram, the movable member 352 includes a plurality of second conversion structures 3521. The plurality of second conversion structures 3521 are interconnected with a plurality of first conversion structures 3514. Each second conversion structure 3521 is, for example, a cylindrical structure, and each cylindrical structure is disposed through an oblique through-hole in the linkage member 351.
[0043] As described above, in the actual assembly process, the user can first insert the multiple second conversion structures 3521 (cylindrical structures) of the movable member 352 into the multiple first conversion structures (oblique through holes) of the linkage member 351. Then, the linkage member 351 and the movable member 352 are placed together into the slide groove 322. Then, the elastic member 34 is installed in the body 32. Then, multiple screws are used to fix one end of the pressing member 33 and the movable member 352 to each other, and multiple screws are used to fix the movable outer shell 353 and the movable member 352 to each other.
[0044] like Figure 5 As shown, the linkage 351 may further include a lateral limiting through hole 3515, which passes through the axial structure 3511. An auxiliary locking fastener S2 passes through the lateral limiting through hole 3515, and a portion of the auxiliary locking fastener S2 is locked to the body 32. When the linkage 351 moves relative to the body 32, the lateral limiting through hole 3515 moves correspondingly to the auxiliary locking fastener S2. The auxiliary locking fastener S2 and the lateral limiting through hole 3515 together limit the range of motion of the linkage 351 relative to the body 32. Since the pressing member 33 is fixed to the linkage 351 by screws, the auxiliary locking fastener S2, while limiting the range of motion of the linkage 351 relative to the body 32, also limits the range of motion of the pressing member 33 relative to the body 32.
[0045] like Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, under normal circumstances where the carbon ribbon (not shown in the figure) has been wound around the recycling shaft 3, if the pressing member 33 is not pressed, the elastic member 34 will push against the pressing member 33, causing the pressing member 33 to be in a protruding position. At the same time, the auxiliary locking member S2 is generally located at one end of the lateral limiting through hole 3515 (the end of the lateral limiting through hole 3515 away from the pressing member 33), and each of the second conversion structures 3521 (cylindrical structure) is generally located at one end (i.e., the front end) of each of the first conversion structures 3514 (oblique through hole), while the movable outer shell 353 is correspondingly located in an open position away from the main body 32. At this time, the overall outer diameter of the recycling shaft 3 is relatively large.
[0046] like Figure 2 , Figure 3 , Figure 6 , Figure 7As shown, it is worth mentioning that since the pressing member 33 is fixed to the linkage member 351 of the two movable components 35 at the same time, when the pressing member 33 is not pressed, the movable housing 353 of the two movable components 35 are in the open position.
[0047] like Figures 8 to 10 As shown, when the pressing member 33 is pressed, Figure 2 , Figure 3 , Figure 6 The recycling shaft 3 shown will be transformed into Figure 8 , Figure 9 and Figure 10 The state shown. During the transition, the linkage 351 will be pushed by the pressing member 33, and... Figure 6 The rightward movement is achieved, while each oblique perforation (first conversion structure 3514) will correspond to the direction. Figure 6 The movable outer shell 353, connected to each cylindrical structure (second conversion structure 3521) and the moving member 352, will move towards the main body 32 under its own weight. Thus, the movable outer shell 353 will be moved from the rightward direction. Figure 6 Move to the indicated opening position. Figure 10 The retracted position is shown, and at the same time, the auxiliary locking device S2 will be located at the other end of the lateral limiting through hole 3515.
[0048] In other words, as stated above, Figure 6 This image shows the recycling shaft 3 in its normal state of collecting recycled carbon ribbon, with each movable housing 353 in the open position protruding from the main body 32. When the user wishes to remove the recycled carbon ribbon from the recycling shaft 3, the user simply needs to press the pressing member 33 to move each movable housing 353 toward the main body 32, thereby reducing the overall outer diameter of the recycling shaft 3. This prevents the movable housings 353 from contacting the recycled carbon ribbon, allowing the user to easily pull the recycled carbon ribbon away from the recycling shaft 3.
[0049] As described above, the recycling spindle and printing equipment including the recycling spindle of this application, through the design of the body, pressing element, elastic element and moving component, allow users to easily remove the recycled ribbon from the recycling spindle by pressing the pressing element.

Any person skilled in the art may make some modifications or alterations to other equivalent embodiments without departing from the scope of the technical means disclosed in this application, but these should still be regarded as the technology or embodiments that are substantially the same as those of this application.
