[0002] Medical film printers are indispensable imaging instruments in the medical field. They convert medical images into high-quality printed images, facilitating diagnosis and treatment for doctors. The film, as the printer's output medium, is typically stored in different film cassettes in stacks of dozens to hundreds of sheets. During the film printing process, the film is transported from the cassettes to the print head through the printing channel.

[0003] In general products, a film printer often has two or more film cassettes to store different sizes of film and print different sizes of film according to the actual needs of the end user.

[0004] In practical use cases of film printers, film is transported from different film cassettes to the print head through channels of varying lengths. During this process, mechanical or electrical malfunctions often cause the film to fail to be properly delivered, resulting in the film being suspended inside the channel and preventing the equipment from functioning correctly.

[0005] For films stuck inside the equipment, they need to be removed to reset the equipment and allow it to function normally. Currently, most products on the market require disassembly using specific tools to handle abnormal films, which necessitates guidance, is time-consuming, and impacts the efficiency of normal film printing.

However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0024] Example 1, see Figure 1-3 ,

[0025] A channel-maintainable printing mechanism, characterized in that it includes a printing body 1, a printhead assembly 2, a rotating shaft 3, a rear cover plate 4, and a film feed cassette 5; the upper part of the printing body 1 is rotatably connected to the rotating shaft 3, and the printhead assembly 2 is fixedly connected to the rotating shaft 3; the film feed cassette 5 is arranged in layers on the printing body; the two sides of the film feed cassette 5 are horizontally pushed, pulled, and slidably connected to the printing body 1; a functional horizontal plate 11 is provided at the rear end of the travel of the film feed cassette 5, and the two ends of the functional horizontal plate 11 are fixedly connected to the two sides inside the printing body 1; the rear cover plate 4 is movably connected to the rear side of the printing body 1; and an opening and closing connector 6 is provided on the printing body 1.

[0026] Preferably, the opening and closing connector 6 includes a damping rotating shaft device 61; the damping rotating shaft device 61 includes a stop post 611, a hollow damping rotating shaft 612 and a limiting block 613; at least one end of the rotating shaft 3 is sleeved with the hollow damping rotating shaft 612; the hollow damping rotating shaft 612 and the limiting block 613 are detachably and fixedly connected; the limiting block 613 is fixedly connected to the printing body 1.

[0027] Furthermore, a stop post 611 is integrally fixed at one end of the rotating shaft 3 near the limiting block 613; the maximum opening and closing angle range of the stop post 611, which is damped and rotates with the limiting block 613 fixedly connected to the printing body 1, is greater than 90 degrees and less than 120 degrees.

[0028] The damping shaft device 61 can be installed at one end of the shaft 3 or at both ends of the shaft 3.

[0029] When the printing film is suspended and stuck in the printhead, the printhead assembly 2, which is horizontal during printing, can be rotated. The rotating shaft 3 will rotate synchronously. When the stop post 611 fixed on the rotating shaft 3 contacts and cooperates with the limit block 613 to achieve the limit, the printhead assembly 2 can be kept open under the action of gravity, which provides convenience for the next step of printing channel maintenance.

[0030] Example 2, see Figure 4 and 5 The easy-maintainable printing mechanism provided in this embodiment is an improvement on embodiment 1 with the following modifications:

[0031] Preferably, the opening and closing connector 6 further includes a rear cover opening and closing device 62; the rear cover opening and closing device 62 includes a pot magnet 621, a pot magnet contact surface 622, and a first right-angle connecting block 623; the pot magnet contact surface 621, which is fixedly connected to the printing body 1, is fixedly provided on the upper part of the rear cover plate 4; first convex shaft holes 624 are fixedly opened on both sides below the rear cover plate 4; a first convex shaft 625, which is rotatably connected to the first convex shaft hole 624, is fixedly provided on the printing body 1; one right-angle side of the first right-angle connecting block 623 is fixedly connected to the upper part of the rear cover plate 4; the pot magnet 621 is fixedly connected to the other right-angle side of the first right-angle connecting block 623; the pot magnet 621 is magnetically connected to the pot magnet contact surface 622.

[0032] Furthermore, the rear cover opening and closing device 62 also includes a pull rod device 63; the pull rod device 63 includes a diagonal pull rod 631; one end of the diagonal pull rod 631 is fixedly provided with a second convex shaft 632, and the other end is provided with a sliding limiting groove 633; ​​at least one side of the rear cover plate 4 is fixedly connected to a right-angle side of a second right-angle connecting block 634; a rotating boss 635 is fixedly provided above the first convex shaft 625; the rotating boss 635 is rotatably connected to the second convex shaft 632; the diagonal pull rod 631 is fixedly connected to the other right-angle side of the second right-angle connecting block 634 through a limiting bolt 636 provided in the sliding limiting groove 633.

[0033] The pull rod device 63 can be installed on one side of the rear cover plate 4 or on both sides of the rear cover plate 4.

[0034] When the printing film is stuck in the channel near the rear cover, the magnetic connection of the magnet 621 can be used to quickly and easily open the rear cover 4 of the printing mechanism, allowing for maintenance of the film stuck in the channel near the rear cover 4. The rear cover 4 is also connected to the printing body via a pull rod device 63. When the rear cover 4 is opened using the magnetic connection of the magnet 621, the limiting bolt 636 can slide within the sliding limiting groove 633 until it reaches the end of the sliding limiting groove 633. At this point, the rear cover 4 is pulled by the diagonal pull rod 631 and stops opening downwards. This not only provides space for channel maintenance but also facilitates the quick repositioning of the rear cover 4 after maintenance, saving maintenance time.

[0035] Example 3, see Figure 6 The easy-maintainable printing mechanism provided in this embodiment is an improvement on embodiment 2 with the following modifications:

[0036] Preferably, the opening and closing connector 6 includes a ball-operated locking device 64; the ball-operated locking device 64 includes a ball-operated locking tongue 641 and a ball-operated locking body 642; the rear end of the feeding box 5 is fixedly connected to the ball-operated locking tongue 641; the functional horizontal plate 11 is fixedly provided with a ball-operated locking body 642 that can cooperate with the ball-operated locking tongue 641 for locking.

[0037] When the film being printed is stuck in the channel near the film supply cassette 5, it can be quickly pulled out by sliding horizontally between the two sides of the film supply cassette 5 and the printing body 1, combined with the ball-operated locking device 64. This allows for maintenance of the film stuck in the channel near the film supply cassette 5. After maintenance, the film supply cassette 5 can be quickly reset and locked by the ball-operated locking device 64, improving maintenance efficiency and the connection stability between the film supply cassette 5 and the printing body 1, further reducing the probability of film getting stuck in the channel near the film supply cassette 5.

[0038] Compared with existing technologies, this invention allows for the quick opening and resetting of various printing film channels and printhead areas without the need for tools, simply by setting up simple opening and closing connectors on the equipment. This simplifies the handling of abnormal film, greatly shortens maintenance time, reduces maintenance difficulty, and improves printer maintenance efficiency. It also provides significant convenience for the daily maintenance and cleaning of various printing film channels and printhead areas.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it.
