Description

Technical Field

[0001] This utility model relates to the field of printing press technology, specifically to a feeding roller mounting structure for a digital label printing machine. Background Technology

[0002] Label printing machines, also known as self-adhesive printing machines, are equipment for printing labels and trademarks. For digital label printing machines, the feeding pressure roller is also an important component, which can play a role in pressing the labels during the feeding process to prevent them from easily shifting.

[0003] Chinese Utility Model Patent Publication No. CN220220157U discloses a multi-functional label printing machine for digital devices. The specification of this multi-functional label printing machine for digital devices describes how the machine utilizes the cooperation of various components, including a sliding plate, a fixed base, screw sleeves, a drive motor, threaded rods, a movable plate, a connecting base, a driven bevel gear, a drive bevel gear, and a connecting rod. This allows the machine to easily drive two threaded rods to rotate forward, facilitating the closing of two screw sleeves. This, in turn, causes the movable plate to gradually rotate towards a vertical position, allowing the two movable plates to push the sliding plate, which in turn moves the printing roller downwards to contact the label fabric for printing. This improves the practicality of the printing machine. However, while the machine can perform printing, it lacks a design for installing a feeding pressure roller, making it difficult to install and replace quickly after prolonged use, resulting in poor practicality.

[0012] Preferably, a limit bolt is threaded to one end of the fixing frame near the pressure roller body, and the limit bolt passes through the fixing frame and extends to the inner edge of the top seat.

[0013] Through the above technical solution and the design of the limit bolt, after the two are aligned, the limit bolt is used to lock them together, which can avoid misalignment during installation, thus avoiding affecting the normal installation and facilitating subsequent maintenance and replacement.

[0014] Preferably, the diameter of the connecting block is the same as the diameter of the through groove, and a spring is fixedly installed at one end of the connecting block near the fixed sleeve, while the other end of the spring is fixedly installed with the fixed sleeve.

The top seat 601 has a groove 602 at one end near the mounting frame assembly 5, and a through groove 603 communicating with the groove 602 is provided through the inner edge of the top seat 601. The limiting component 7 includes a fixed sleeve 701 fixedly installed inside the through groove 603. A limiting post 702 is slidably connected at the inner edge of the fixed sleeve 701. A connecting block 703 and a limiting block 704 are fixedly installed from top to bottom at one end of the limiting post 702 near the limiting groove 503. The diameter of the limiting block 704 is the same as the diameter of the limiting groove 503.

[0023] Specifically, at least two identical longitudinal profile frames 501 are provided, and a transverse profile frame 502 is fixedly installed between the two longitudinal profile frames 501. Multiple limiting grooves 503 are equidistantly distributed along the horizontal line of the transverse profile frame 502. The advantage is that, through the cooperation between the transverse profile frame 502 and the longitudinal profile frame 501, after the longitudinal profile frame 501 is fixedly installed with the printer base 4, the longitudinal profile frame 501 can be installed between the two longitudinal profile frames 501, which can facilitate its quick installation. At the same time, the design of multiple limiting grooves 503 can facilitate the subsequent fixing of the feeding pressure roller assembly 6.

[0024] Specifically, a positioning groove 604 is provided at one end of the top seat 601 near the fixed frame 605, and a positioning post 607 is fixedly installed at one end of the fixed frame 605 near the top seat 601.

[0026] Example 2: Figure 2-9 As shown, this is an improvement on the previous embodiment.

[0027] Specifically, a limit bolt 606 is threadedly connected to one end of the fixed frame 605 near the pressure roller body 610. The limit bolt 606 passes through the fixed frame 605 and extends to the inner edge of the top seat 601. The advantage is that, through the design of the limit bolt 606, after the two are aligned, the limit bolt 606 is used to lock the two together, which can avoid misalignment during installation, thus affecting normal installation and facilitating subsequent maintenance and replacement.

[0028] Specifically, the diameter of the connecting block 703 is the same as the diameter of the through groove 603. A spring 705 is fixedly installed at one end of the connecting block 703 near the fixed sleeve 701, and the other end of the spring 705 is fixedly installed with the fixed sleeve 701.

[0029] Specifically, multiple feeding roller assemblies 6 and limiting grooves 503 are provided, and the multiple feeding roller assemblies 6 and limiting grooves 503 are distributed at equal intervals. The advantage is that through the cooperation between multiple feeding roller assemblies 6 and limiting grooves 503, the feeding roller assembly 6 can slide on the mounting frame assembly 5, and then be adjusted according to the paper width, thereby improving its practicality.

[0030] Working Principle: During use, the cooperation between the horizontal profile frame 502 and the vertical profile frame 501 allows the vertical profile frame 501 to be installed between two vertical profile frames 501 after it has been fixedly installed to the printer base 4, facilitating quick installation. The design of multiple limiting grooves 503 facilitates subsequent fixing of the feeding pressure roller assembly 6. The design of the positioning groove 604 and positioning post 607 allows the positioning post 607 to be inserted into the positioning groove 604 when installing the top seat 601 and the fixing frame 605, achieving quick positioning. The design of the rotating rod 608 and the pressure roller body 610 allows the pressure roller body 610 to be mounted on the fixing frame 605 after the top seat 601 and the fixing frame 605 are installed, facilitating the pressing of printed items on the digital label printing machine base 1. The design of the limiting bolt 606 further enhances this effect. After the two are aligned, they are locked together by the limit bolt 606, which can prevent misalignment during installation and thus affect normal installation. It also facilitates subsequent maintenance and replacement. With the design of spring 705, when installing top seat 601, top seat 601 can be inserted into the inner edge of horizontal profile frame 502 through slide groove 602, and then slide through slide groove 602. When adjusted to the appropriate position, the connecting block 703 can be driven by the limit post 702 to deform the spring 705. Then, when it moves above the limit groove 503, the limit post 702 is released, which can achieve quick positioning and realize the quick installation of feeding pressure roller assembly 6 and mounting frame assembly 5. Through the cooperation between multiple feeding pressure roller assemblies 6 and limit grooves 503, feeding pressure roller assembly 6 can slide on mounting frame assembly 5, and then be adjusted according to paper width to improve its practicality.
