Description

Technical Field

[0001] This invention relates to the field of printer technology, and more specifically to a printer roller holder structure. Background Technology

[0002] As printer technology continues to develop, its internal structure is becoming increasingly complex, placing higher demands on the fixation and protection of the ribbon cable. In some scenarios, pressure blocks are used to shield the ribbon cable, preventing external interference and improving aesthetics. During installation, the pressure block is fixed to the paper tray cover using clips, screws, or other assembly methods. Therefore, the pressure block needs to be installed separately and with precise operation, increasing assembly steps and time, reducing production efficiency. Furthermore, as a separate component, the pressure block is prone to loosening or falling off during use.

[0003] Therefore, this application studies a printer roller holder structure that allows for easy installation of the pressure block and provides high stability. Utility Model Content

[0035] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0036] This application discloses a printer roller holder structure. (Refer to...) Figure 1 and Figure 2 The printer's roller holder 1 structure includes a roller holder 1, a paper tray cover 2, and a pressure block 3. The pressure block 3 is integrally formed on one side of the roller holder 1 along its length. The pressure block 3 has an arc-shaped structure. When the paper tray cover 2 is installed, one side of the pressure block 3 fits against the inner wall of the paper tray cover 2. A cable routing groove 4 is provided on the side of the pressure block 3 facing the paper tray cover 2. When the paper tray cover 2 is placed on the roll of paper, the side of the pressure block 3 away from the paper tray cover 2 has the same curvature as the outer periphery of the roll of paper. By forming the pressure block 3 on one side of the roller holder 1, there is no need to set up a separate installation structure for the roller holder 1, which simplifies the printer structure. Furthermore, due to the arc shape of the paper tray cover 2 and the pressure block 3, it is difficult to align the pressure block 3 when installed separately. However, this application uses an integral forming design to limit the position of the pressure block 3 while installing the roller holder 1 and the paper tray cover 2, improving installation convenience and stability.

[0037] Reference Figure 2 In some embodiments, a through channel 5 is provided at the connection between the rubber roller frame 1 and the pressure block 3, and the through channel 5 connects to the cable tray 4. This allows the wire harness to be arranged more smoothly in the cable tray 4 and to dissipate heat better.

[0038] In some embodiments, ribs 6 are spaced apart along the length of the cable tray 4. The ribs 6 can further fix the cable harness, making the installation of the cable harness more stable, while the pressure block 3 can better cover the cable harness.

[0039] In some embodiments, the paper tray cover 2 is provided with a snap-fit ​​groove 7. During installation, the end of the pressure block 3 away from the glue roller frame 1 is inserted into and confined within the snap-fit ​​groove 7. The width of the snap-fit ​​groove 7 is slightly larger than the width of the pressure block 3, which can limit the pressure block 3 to the left and right while also facilitating the insertion of the pressure block 3 into the snap-fit ​​groove 7.

[0040] In some embodiments, a rotating block 8 is provided on the paper tray cover 2, and a snap-fit ​​groove 7 is formed in the rotating block 8. The position of the pressure block 3 corresponds to the position of the rotating block 8, that is, when the pressure block 3 is attached to the paper tray cover 2, one end is located in the snap-fit ​​groove 7. The rotating block 8 is used to rotate and install with the printer housing, so that the paper tray cover 2 can be rotated to open or close. The snap-fit ​​groove 7 formed in the rotating block 8 simplifies the structure, eliminates the need for a separate structural groove, saves manufacturing costs, saves printer space, and is conducive to the miniaturization of the printer.

[0041] Reference Figure 3 and Figure 4In some embodiments, the paper tray cover 2 is further provided with a limiting groove 9, and the pressure block 3 is provided with a limiting element 15. During installation, the limiting element 15 slides along the inner wall of the paper tray cover 2 and is inserted into the limiting groove 9. In this embodiment, the rotating block 8 is also provided with a clearance groove 10. The width of the clearance groove 10 is greater than the width of the pressure block 3, and the width of the limiting groove 9 is less than the width of the snap-fit ​​groove 7, and they are interconnected. The limiting groove 9 and the clearance groove 10 are interconnected. The pressure block 3 is inserted along the clearance groove 10, and the limiting element 15 is inserted into the limiting groove 9. The installation position of the pressure block 3 is positioned by the clearance groove 10, and the limiting element 15 is inserted into the limiting groove 9 to prevent the pressure block 3 from detaching from the paper tray cover 2.

[0042] In some embodiments, two limiting grooves 9 are provided, that is, the two side walls of the clearance groove 10 are both through the limiting groove 9, and the two sides of the pressure block 3 are provided with limiting members 15, which are provided one-to-one with the limiting grooves 9. This allows the pressure block 3 to be limited more stably.

[0043] Reference Figure 1 and Figure 3 In some embodiments, one end of the roller frame 1 has a first rotating groove 11, and one end of the roller is inserted into the first rotating groove 11. One end of the paper tray cover 2 has a second rotating groove 12, and the other end of the roller is inserted into the second rotating groove 12. During installation, one end of the roller frame 1 is inserted into the first rotating groove 11, the roller frame 1 is tilted so that the other end of the roller is inserted into the second rotating groove 12, and then the roller frame 1 is pushed in so that the pressure block 3 is engaged in the engagement groove 7 through the clearance groove 10. One side is limited by the roller frame 1, and the other side is limited by the paper tray cover 2. There is no need to install a separate fixing structure for the roller on the other side of the roller frame 1, which simplifies the structure, saves costs, and miniaturizes the printer. Moreover, the limitation method of the paper tray cover 2 facilitates operation, as only the second rotating groove 12 needs to be inserted.

[0044] Continue to refer to Figure 1 In some embodiments, the roller frame 1 has a connecting hole 13, and the paper tray cover 2 has a threaded hole 14. Bolts are screwed into the threaded hole 14 through the connecting hole 13. In this embodiment, one connecting hole 13 is provided at each end of the roller frame 1, and the threaded hole 14 is provided accordingly, which facilitates the fixed installation of the roller frame 1.

[0045] The implementation principle of the printer roller frame 1 structure in this application embodiment is as follows: the pressure block 3 is integrally formed on the roller frame 1, and the pressure block 3 is set in an arc-shaped structure, so that the pressure block 3 fits against the inner wall of the paper tray cover 2, which effectively solves the problem of fixing and blocking the ribbon cable, and makes the pressure block 3 highly stable. At the same time, it simplifies the internal structure of the printer and improves the assembly efficiency.
