Description

Technical Field

[0001] The utility model relates to the technical field of printers, in particular to a paper limiting structure and a printer. Background Art

[0002] In the printer industry, the design of paper limiting mechanisms is crucial for ensuring the stability and accuracy of paper or paper rolls during the printing process. To accommodate paper or paper rolls of varying widths, for example, existing patent application number "201620068416.1," which discloses a "Printer Guide Rail Synchronous Damping Mechanism," employs a common adjustment method based on the linkage of two racks and a damping gear. This mechanism effectively controls the relative position of the two racks through the resistance of the damping gear, thereby achieving precise positioning of the paper or paper roll.

[0003] However, although this adjustment mechanism can work normally in most cases, it has a significant flaw: the reliability issue of the damping gear. In actual applications, the damping gear may fail due to long-term use, wear or the influence of external factors. Once the damping gear fails, the resistance originally provided by it will not be able to maintain the relative position stability between the two racks, resulting in the racks possibly moving away from each other. This unexpected movement will directly destroy the function of the paper limiting structure, making it impossible for the paper or paper roll to be effectively limited during the printing process, which may cause printing misalignment, paper jams and other faults, seriously affecting printing quality and efficiency. To this end, we provide a paper limiting structure and printer to solve the above problems. Utility Model Content

[0006] A paper limiting structure is provided, the paper limiting structure being located in a paper bin of a printer and comprising:

[0007] A first support shaft and a second support shaft, wherein the first support shaft and the second support shaft are both fixedly mounted in the paper bin and are arranged parallel to each other;

[0008] A paper limiting plate, wherein the second support shaft is slidably provided on the first support shaft and the second support shaft, and the paper limiting plate can move along the axial direction of the first support shaft and the second support shaft;

[0009] an adjusting plate, the adjusting plate being rotatably mounted on the first support shaft;

[0010] an abutting protrusion, the abutting protrusion being provided on the outer surface of the adjusting plate and being capable of abutting against the inner wall of the paper bin when the adjusting plate rotates about the first support shaft;

[0011] Wherein, a clamping structure is provided between the paper limiting plate and the adjusting plate, and the adjusting plate rotates through the clamping structure so that the paper limiting plate is clamped with the adjusting plate.

[0012] Preferably, the clamping structure includes a first clamping block arranged on the outer wall of the limiting paperboard, and the clamping structure also includes a second clamping block arranged on the adjustment plate and adapted to the first clamping block, and the adjustment plate rotates to drive the second clamping block to clamp with the first clamping block.

[0014] Preferably, the first clamping block and the second clamping block are both tooth-shaped; there are N first clamping blocks, and N≥1 is satisfied.

[0015] Preferably, a limiting groove is provided on the side wall of the elastic arm, the limiting groove and the second clamping block are located on the same side wall, and the frame where the first clamping block is located is clamped in the limiting groove.

[0016] Preferably, a limited rotation structure is further provided between the limiting paperboard and the adjustment plate, the limited rotation structure includes a rotation hole opened through the surface of the limiting paperboard, a rotating shaft is provided on the surface of the limiting paperboard facing the limiting paperboard, and a limited structure is provided between the rotating hole and the rotating shaft.

[0017] Preferably, the limiting structure includes a limiting surface provided on the outer surface of the end portion of the rotating shaft, and the opening outer surface of the rotating hole is provided with a limiting surface, and the limiting surface is located between the limiting block and the adjusting plate.

[0018] Preferably, a locking mark is provided on the surface of the limiting paper board.

[0019] Preferably, an unlocking mark is provided on the surface of the limiting paper board, and an indicating arrow is provided between the locking mark and the unlocking mark.

[0020] The present application also provides a printer, comprising a paper bin, wherein the paper bin is provided with any of the above-described paper limiting structures.

[0021] The utility model has the following advantages:

[0022] 1. The utility model causes the abutting protrusion to abut against the inner wall of the paper bin during the rotation of the adjusting plate. At this time, the limiting paperboard is clamped and connected to the adjusting plate under the action of the clamping structure. Since the abutting protrusion abuts against the inner wall of the paper bin, the force applied to the limiting paperboard to move is transmitted through the clamping structure, so that the force acting on the second support shaft and the outer surface of the first support shaft by the limiting paperboard is increased. Therefore, the friction between the limiting paperboard and the second support shaft as well as the first support shaft is increased. At this time, the limiting paperboard cannot slide about the first support shaft and the second support shaft under the action of the friction force, thereby realizing the paper limiting function.

[0023] 2. In the present invention, during the rotation of the adjustment plate, the second clamping block moves to the position of the first clamping block, so that the first clamping block is engaged with the second clamping block. Since the abutting protrusion abuts against the inner wall of the paper bin, the inner wall of the paper bin will react to the abutting protrusion, and then act on the adjustment plate. The force is then applied to the limiting paperboard through the engagement transmission of the first clamping block and the second clamping block, giving the limiting paperboard a force with a movement tendency. For this reason, the acting force between the limiting paperboard and the first support shaft and the second support shaft is increased, and the friction force is increased.

[0024] 3. The utility model arranges the second clamping block on the elastic arm, so that the elastic arm can undergo a certain deformation when the second clamping block is clamped with the first clamping block, thereby smoothly clamping the second clamping block with the first clamping block.

Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0036] like Figure 1 — Figure 6 The embodiment shown.

[0037] A paper limiting structure is provided. The paper limiting structure is located in a paper bin of a printer. The paper limiting structure comprises a first support shaft 100 and a second support shaft 200 , a paper limiting board 300 , an adjusting plate 400 , and an abutting protrusion 500 .

[0038] The first support shaft 100 and the second support shaft 200 are both fixedly installed in the paper bin, and the first support shaft 100 and the second support shaft 200 are arranged parallel to each other, and the second support shaft 200 is slidably arranged on the first support shaft 100 and the second support shaft 200, and the limiting paper board 300 can move along the axial direction of the first support shaft 100 and the second support shaft 200, and the adjusting plate 400 is rotatably installed on the first support shaft 100, and the abutting protrusion 500 is arranged on the outer surface of the adjusting plate 400, and when the adjusting plate 400 rotates about the first support shaft 100, the abutting protrusion 500 can abut against the inner wall of the paper bin, wherein a clamping structure is provided between the limiting paper board 300 and the adjusting plate 400, and the adjusting plate 400 rotates through the clamping structure to clamp the limiting paper board 300 with the adjusting plate 400.

[0039] See Figure 1 and Figure 2 As shown, the first support shaft 100 and the second support shaft 200 are arranged parallel to each other and are installed on the side of the paper bin, that is, one end of the first support shaft 100 and one end of the second support shaft 200 are fixedly connected to one of the inner side surfaces of the paper bin, and the other end of the first support shaft 100 and the other end of the second support shaft 200 are connected to the other inner side surface of the paper bin, and the limiting paper board 300 is slidably arranged on the first support shaft 100 and the second support shaft 200. Specifically, the limiting paper board 300 is provided with a connecting hole (not marked in the figure) adapted to the first support shaft 100 and the second support shaft 200. In order to ensure that the limiting paper board 300 can move smoothly along the guide of the first support shaft 100 and the second support shaft 200, the limiting paper board 300 is clearance-matched with the first support shaft 100 and the second support shaft 200 to prevent the limiting paper board 300 from moving unsmoothly.

[0040] In the initial state, the limiting paperboard 300 can move under the guidance of the first support shaft 100 and the second support shaft 200, and the position of the limiting paperboard 300 is adjusted according to the width of the paper. When the limiting paperboard 300 moves to the predetermined position, that is, the limiting paperboard 300 can limit the paper. In order to maintain the state of limiting the paper, it is necessary to rotate the adjusting plate 400. The adjusting plate 400 rotates about the first support shaft 100. After rotating to a certain angle, the abutting protrusion 500 will abut against the inner wall of the paper bin, and the second clamping block 700 moves toward the first clamping block 600, and the second clamping block 700 is engaged with the first clamping block 600. At this time, When the abutment protrusion 500 abuts against the inner wall of the paper bin, the inner wall of the paper bin will give the abutment protrusion 500 a reverse rotation force, and this force will be transmitted through the engagement of the second clamping block 700 and the first clamping block 600, and then transmitted to the limiting paperboard 300, so that the limiting paperboard 300 has a tendency to move. At this time, the contact force between the limiting paperboard 300 and the outer surface of the first support shaft 100 and the outer surface of the second support shaft 200 increases, and for this reason, the friction force between the limiting paperboard 300 and the first support shaft 100 and the second support shaft 200 increases. The friction force is used to prevent the limiting paperboard 300 from moving, thereby achieving the positioning of the limiting paperboard 300 and the limitation of the paper.

[0041] It should be noted that, in order to meet the needs in practice, the inner wall of the paper bin and the abutment protrusion 500 can undergo a certain degree of deformation at the abutment point, that is, the inner wall of the paper bin has a certain elasticity, which provides power for the abutment force between the limiting paper board 300 and the first support shaft 100 and the second support shaft 200, or the adjustment plate 400 itself can achieve a certain elastic deformation. Specifically, it can be designed according to needs in practice, that is, as long as the friction between the limiting paper board 300 and the first support shaft 100 and the second support shaft 200 is increased by rotating the adjustment plate 400, it can be sufficient.

[0042] The clamping structure includes a first clamping block 600 provided on the outer wall of the limiting paperboard 300, and the clamping structure also includes a second clamping block 700 provided on the adjustment plate 400 and adapted to the first clamping block 600. The adjustment plate 400 rotates to drive the second clamping block 700 to clamp with the first clamping block 600.

[0043] See Figure 2 and Figure 3 As shown, the second clamping block 700 is driven to rotate together with the adjusting plate 400 by rotating, and the second clamping block 700 is rotated to the position of the first clamping block 600, so that the second clamping block 700 is engaged with the first clamping block 600, and the force acting on the adjusting plate 400 is transmitted to the limiting paper board 300.

[0044] An elastic arm 800 is provided on the outer wall surface of the adjustment plate 400 . A deformation groove is defined between the elastic arm 800 and the adjustment plate 400 . The second clamping block 700 is provided on the elastic arm 800 .

[0045] Continue reading Figure 2 and Figure 3 As shown, in order to enable the second clamping block 700 to be smoothly engaged with the first clamping block 600, when the second clamping block 700 is in contact with the first clamping block 600 and is about to be engaged, the first clamping block 600 will give the second clamping block 700 a force to deviate, and the force will be transmitted to the elastic arm 800 through the second clamping block 700, and the elastic arm 800 will undergo a certain deformation, so that the second clamping block 700 can smoothly enter the position of the first clamping block 600, so that the second clamping block 700 can be engaged with the first clamping block 600. At this time, the first clamping block 600 no longer gives the second clamping block 700 a force to deviate, and the elastic arm 800 returns to its initial state under the action of its own elastic force.

[0046] The first clamping block 600 and the second clamping block 700 are both tooth-shaped; there are N first clamping blocks 600, and N≥1 is satisfied.

[0047] For example, the number of the first card blocks 600 can be 1, 2, 3, 4, etc. The number of the first card blocks 600 can be designed according to needs, and the specific number is not limited here.

[0048] See Figures 4 to 7 As shown, the first clamping block 600 and the second clamping block 700 are both in the shape of gear teeth, and the engagement between the first clamping block 600 and the second clamping block 700 is achieved through the meshing between the teeth. In addition, in this embodiment, there are three first clamping blocks 600, that is, N in the above is 3. Accordingly, the friction force between the limiting paperboard 300 and the first support shaft 100 and the second support shaft 200 also has three levels, that is, when the second clamping block 700 is clamped with different first clamping blocks 600, the friction force between the limiting paperboard 300 and the first support shaft 100 and the second support shaft 200 is also different. In practice, the second clamping block 700 can be clamped with the first clamping block 600 at different positions as needed.

[0049] A limiting groove 810 is defined on the side wall of the elastic arm 800 . The limiting groove 810 and the second clamping block 700 are located on the same side wall. The frame where the first clamping block 600 is located is clamped in the limiting groove 810 .

[0050] See Figure 3 、 Figure 5 and Figure 7As shown, in order to enable the limiting paperboard 300 and the adjustment plate 400 to move synchronously, in this embodiment, a limiting groove 810 is provided on the elastic arm 800, and the limiting groove 810 and the second clamping block 700 are located on the same side wall, and the limiting groove 810 is located on the side of the second clamping block 700 away from the first clamping block 600. The frame of the first clamping block 600 is deeply inserted into the limiting groove 810, so that the frame and the limiting groove 810 are clamped. Since the frame is clamped in the limiting groove 810, the limiting paperboard 300 and the adjustment plate 400 are limited in the axial direction of the first support shaft 100. At this time, the limiting paperboard 300 and the adjustment plate 400 can move synchronously in the axial direction of the first support shaft 100, but do not limit the rotational movement of the adjustment plate 400. Specifically, the frame of the first clamping block 600 is an arc surface, so that when the adjustment plate 400 rotates, the frame does not interfere with the movement of the adjustment plate 400.

[0051] A limited rotation structure 900 is further provided between the limiting paperboard 300 and the adjustment plate 400. The limited rotation structure 900 includes a rotation hole 910 that penetrates the surface of the limiting paperboard 300. A rotating shaft 920 is provided on the surface of the limiting paperboard 300 facing the limiting paperboard 300. A limited structure 930 is provided between the rotation hole 910 and the rotating shaft 920.

[0052] The limiting structure 930 includes a limiting block 931 provided on the outer surface of the end of the rotating shaft 920 . The outer surface of the opening of the rotating hole 910 is provided with a limiting surface 932 . The limiting surface 932 is located between the limiting block 931 and the adjusting plate 400 .

[0053] See Figure 3 As shown, in order to further ensure that the position between the limiting paperboard 300 and the adjustment plate 400 does not change along the axial direction of the first support shaft 100, a limiting rotation structure 900 is required to limit the position between the limiting paperboard 300 and the adjustment plate 400. Specifically, in this embodiment, the limiting block 931 is in contact with the limiting surface 932 to achieve clamping, so that the position between the limiting paperboard 300 and the adjustment plate 400 along the axial direction of the first support shaft 100 does not change. In order to prevent the adjustment plate 400 from interfering with the rotating shaft 920 during rotation, a rotating hole 910 is opened on the adjustment plate 400, and the rotating shaft 920 is located in the rotating hole 910. The rotating hole 910 is used to avoid the rotating shaft 920 during rotation of the adjustment plate 400.

[0054] Continue reading Figure 3As shown, the limiting surface 932 is located at the opening position of the rotating hole 910, and the limiting surface 932 is located between the limiting block 931 and the limiting paperboard 300. If the adjustment plate 400 moves along the direction of the first support axis 100, the limiting surface 932 will contact the limiting block 931, thereby being blocked by the limiting block 931, thereby achieving the position between the limiting paperboard 300 and the adjustment plate 400 along the axial direction of the first support axis 100 does not change.

[0055] Furthermore, when the adjusting plate 400 rotates so that the abutting protrusion 500 abuts against the inner wall of the paper bin, the force from the abutting protrusion 500 reacts on the adjusting plate 400, increasing the force between the adjusting plate 400 and the outer surface of the first support shaft 100. At this time, the friction between the adjusting plate 400 and the first support shaft 100 also increases, making it impossible for the adjusting plate 400 to move about the first support shaft 100. Since the positions of the adjusting plate 400 and the limiting paperboard 300 along the axial direction of the first support shaft 100 remain unchanged, the position of the limiting paperboard 300 is also unchanged. The method of changing the limit paperboard 300 can also be used to fix the position of the limiting paperboard 300. On the contrary, the adjusting plate 400 is rotated in the opposite direction so that the abutting protrusion 500 no longer abuts against the inner wall of the paper bin, and the friction between the adjusting plate 400 and the first support shaft 100 is reduced, and the adjusting plate 400 can move relative to the first support shaft 100. At this time, the friction between the limit paperboard 300 and the first support shaft 100 and the second support shaft 200 is also reduced. At this time, the limit paperboard 300 and the adjusting plate 400 can move synchronously in the axial direction of the first support shaft 100.

[0056] A locking mark 1000 is provided on the surface of the limiting paperboard 300 ; an unlocking mark 1100 is provided on the surface of the limiting paperboard 300 , and an indicating arrow is provided between the locking mark 1000 and the unlocking mark 1100 .

[0057] See Figure 4 As shown, in order to facilitate the indication of the rotation direction of the adjustment plate 400, a locking mark 1000 and an unlocking mark 1100 are respectively provided on the limiting paperboard 300, that is, the rotating adjustment plate 400 drives the second clamping block 700 to move from the unlocking mark 1100 position to the locking mark 1000 position. At this time, the first clamping block 600 and the second clamping block 700 are clamped so that the position of the limiting paperboard 300 is fixed and cannot be moved. At this time, the limiting paperboard 300 is in a locked state; if the second clamping block 700 moves from the locking mark 1000 position to the unlocking mark 1100 position, the clamping state between the first clamping block 600 and the second clamping block 700 can be released. At this time, the limiting paperboard 300 is in an unlocked state, and the limiting paperboard 300 can be moved about the guide of the first support shaft 100 and the second support shaft 200, and can be adjusted according to the width of the paper.

[0058] The locking direction or the unlocking direction is indicated by the arrow between the locking mark 1000 and the unlocking mark 1100. In this embodiment, the direction pointed by the arrow is the locking direction indicated by the unlocking mark 1100 toward the locking mark 1000.

[0059] like Figure 8 As shown, the present application also provides a printer, which includes a paper bin, and the paper limiting structure described in any one of the above items is provided in the paper bin.

[0060] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
