Abstract
Description
Technical Field
[0001] This invention relates to the field of printer technology, and more specifically to a paper roll limiting structure for a printer. Background Technology
[0002] Printer rolls come in various lengths, and the required roll width varies depending on the application scenario. When handling rolls of different lengths, printers need to use a limiting structure to restrict the width of the rolls on both sides. In some scenarios, screws are used to adjust the limiting width, but the adjustment process remains unchanged. In other scenarios, springs are used to adjust the limiting width, but these are prone to fatigue and deformation over long-term use, and maintenance costs are high.
[0003] Therefore, this application studies a paper roll limiting structure for a printer, which makes the structure simple and convenient for limiting. Utility Model Content
[0004] To simplify the structure and facilitate positioning, this application provides a paper roll positioning structure for a printer.
[0005] This application provides a paper roll limiting structure for a printer, which adopts the following technical solution:
[0006] A paper roll limiting structure for a printer includes a mounting shell and two limiting plates. The mounting shell has multiple insertion interfaces spaced apart along its length. One of the limiting plates is inserted into one of the insertion interfaces for positioning. After the paper roll is placed into the mounting shell, one side abuts against the limiting plate, and the other limiting plate is inserted into the corresponding insertion interface at the other end of the paper roll.
[0007] By adopting the above technical solution, multiple insertion interfaces are set on the mounting shell, and two limiting pieces are inserted into the corresponding insertion interfaces to position the two sides of the paper roll. This allows for flexible adaptation to paper rolls of different lengths. Furthermore, the limiting pieces have a simple structure, low cost, and are easy to adjust for positioning.
[0008] Optionally, the insertion interface is divided into two groups with a gap between them, and one group of the insertion interfaces is used to position one end of the roll of paper.
[0009] By adopting the above technical solution, one end of the paper roll can be more accurately positioned in a set of insertion interfaces, while the other end is limited by another set of insertion interfaces, which also ensures that it corresponds to the paper output position and avoids deviation.
[0010] Optionally, the insertion interface is located on the bottom wall of the mounting housing, and the limiting piece has a protruding insertion portion that is inserted into the insertion interface.
[0011] By adopting the above technical solution, the force distribution is made uniform, which enhances the connection stability between the limiting plate and the mounting shell.
[0012] Optionally, inclined guide portions are provided on both sides of the plug portion.
[0013] By adopting the above technical solution, the limiting piece can be smoothly inserted into the interface, reducing the assembly difficulty.
[0014] Optionally, the side wall of the mounting shell is provided with a plurality of limiting holes along the length direction. The limiting holes are set in a one-to-one correspondence with the position of the insertion interface, and one side of the limiting piece is inserted into the limiting hole for limiting.
[0015] By adopting the above technical solution, and with the double limiting mechanism in conjunction with the interface, the stability of the limiting piece is further enhanced, preventing the limiting piece from shifting due to vibration or external force during the printing process.
[0016] Optionally, at least two sets of limiting holes are provided along the two side walls of the mounting shell, and are symmetrically arranged on the two side walls.
[0017] By adopting the above technical solution, the limiting piece can be limited from both sides, which further enhances the symmetry and stability of the limiting structure, and can also better balance the lateral force generated by the paper roll during the printing process, ensuring that the paper roll is uniformly limited on both sides.
[0018] Optionally, the limiting piece has a limiting part with elastic deformation capability; pressing the limiting part into the mounting shell, when the limiting part corresponds to the position of the limiting hole, releasing the limiting part, and the limiting part resets and is inserted into the limiting hole.
[0019] By adopting the above technical solution, the limiting piece can be installed more conveniently, improving convenience and assembly efficiency.
[0020] Optionally, the limiting part is symmetrically arranged along the axis of symmetry of the limiting piece, and the limiting part is symmetrically inserted into the limiting holes on both sides.
[0021] By adopting the above technical solution, the limiting component does not need to be aligned on both sides during installation, which facilitates the installation of the limiting piece.
[0022] Optionally, the limiting part includes a pressing part and an insertion part connected to each other, the limiting piece has a pressing groove to form the pressing part, and the insertion part is located on the side opposite to the pressing groove.
[0023] In summary, this application includes the following beneficial technical effects:
[0024] 1. By setting multiple insertion interfaces on the mounting shell and using two limiting pieces to insert into the corresponding insertion interfaces to position the two sides of the paper roll, it can flexibly adapt to paper rolls of different lengths. The limiting pieces have a simple structure, low cost, and are easy to adjust for positioning.
[0025] 2. The limiting hole and the insertion interface work together to provide double limiting, which further enhances the stability of the limiting piece and prevents the limiting piece from shifting due to vibration or external force during the printing process;
[0026] 3. At least two sets of limiting holes allow the limiting piece to be limited from both sides, further enhancing the symmetry and stability of the limiting structure. It can also better balance the lateral force generated by the paper roll during printing, ensuring that the paper roll is uniformly limited on both sides. Attached Figure Description

[0034] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0035] This application discloses a paper roll limiting structure for a printer. (Refer to...) Figure 1 and Figure 2The printer's roll paper limiting structure includes a mounting shell 1 and two limiting plates 2. The mounting shell 1 has multiple insertion interfaces 3 spaced apart along its length. The spacing between the insertion interfaces 3 can accommodate various common roll paper lengths. One limiting plate 2 is inserted into one of the insertion interfaces 3 for positioning. After the roll paper is placed into the mounting shell 1, one side abuts against the limiting plate 2, and the other limiting plate 2 is inserted into the corresponding insertion interface 3 at the other end of the roll paper. This allows the roll paper to be limited by the two limiting plates 2. Different insertion interfaces 3 can flexibly adapt to roll paper of different lengths. Furthermore, the limiting plate 2 has a simple structure, low cost, and is easy to adjust for positioning.
[0036] Reference Figure 3 In some embodiments, the insertion interface 3 is divided into two groups with a gap between them. One group of insertion interfaces 3 is used to position one end of the paper roll. In this embodiment, one group of insertion interfaces 3 is provided with two positions. The positioning position of the paper roll is adjusted by the two positions, and the paper roll is limited by the position of the other group of insertion interfaces 3, so that the exit position of the paper roll can be limited, thereby improving paper output.
[0037] Reference Figure 3 and Figure 4 In some embodiments, the insertion interface 3 is located on the bottom wall of the mounting shell 1, and the limiting piece 2 has a protruding insertion portion 4, which is inserted into the insertion interface 3. The insertion interface 3 at the bottom ensures uniform force distribution and enhances the connection stability between the limiting piece 2 and the mounting shell 1.
[0038] In some embodiments, inclined guide portions 5 are provided on both sides of the plug portion 4. This makes the plug portion 4 have a trapezoidal structure, so that it can be easily inserted into the plug interface 3 through the guides on both sides.
[0039] Refer again Figure 3 In some embodiments, the side wall of the mounting housing 1 is provided with multiple limiting holes 6 along its length. The limiting holes 6 are set one-to-one with the positions of the insertion interface 3, and one side of the limiting piece 2 is inserted into the limiting hole 6 for limitation. By fixing the limiting piece 2 simultaneously from the side and bottom, the limiting piece 2 can more stably limit the roll of paper.
[0040] In some embodiments, at least two sets of limiting holes 6 are provided along the two side walls of the mounting housing 1, and are symmetrically arranged on the two side walls. In this embodiment, two sets of limiting holes 6 are provided, respectively on the two side walls of the mounting housing 1, and are symmetrically arranged along the central axis of the insertion interface 3. This better balances the lateral force generated by the paper roll during printing, ensuring that the paper roll is uniformly limited on both sides.
[0041] Reference Figure 4In some embodiments, the limiting piece 2 has a limiting part 7, which has elastic deformation capability; pressing the limiting part 7 into the mounting shell 1, and when the limiting part 7 corresponds to the position of the limiting hole 6, releasing the limiting part 7, the limiting part 7 returns to its original position and is inserted into the limiting hole 6. This makes it easier to install the limiting piece 2, improving convenience and assembly efficiency.
[0042] In some embodiments, the limiting part 7 is symmetrically arranged along the axis of symmetry of the limiting piece 2, and the limiting part 7 is symmetrically inserted into the limiting holes 6 on both sides. This allows both sides of the limiting piece 2 to be arbitrarily inserted into the limiting holes 6 on both sides without the need for alignment, making installation convenient.
[0043] Reference Figure 1 and Figure 4 In some embodiments, the limiting part 7 includes a pressing part 71 and an insertion part 72 connected to each other. The limiting piece 2 has a pressing groove 8 to form the pressing part 71, and the insertion part 72 is located on the side opposite to the pressing groove 8. The insertion part 72 is trapezoidal in shape and is integrally formed with the pressing part 71. The pressing part 71 achieves elastic deformation through the pressing groove 8, and after the limiting piece 2 is installed, the pressing part 71 abuts against the side wall of the mounting shell 1, so that the limiting member more stably limits the paper roll.
[0044] The implementation principle of the paper roll limiting structure of a printer in this application embodiment is as follows: by setting multiple insertion interfaces 3 on the mounting shell 1, and by inserting two limiting pieces 2 into the corresponding insertion interfaces 3 respectively, the two sides of the paper roll are positioned, so that it can flexibly adapt to paper rolls of different lengths. Moreover, the limiting piece 2 has a simple structure, low cost, and is easy to adjust its position for limiting.
