[0001] The present application relates to the technical field of printers, in particular to a test sheet printer with self-replacement of printing materials. BACKGROUND

[0002] A self-service printing device can obtain paper information through manual input or scanning. When applied in a hospital, the self-service printing device is generally used to print patient cases, test sheets, registration cards and the like, thereby reducing the queuing time for manually obtaining registration cards and improving the work efficiency of the hospital.

[0003] A general test sheet printer includes a paper accommodating cavity, and test sheet paper is placed in the paper accommodating cavity. When printing is needed, the test sheet paper is placed in the paper accommodating cavity to perform printing. Generally, the printer has only one paper accommodating cavity. Although the test sheet printer of the present stage is provided with a spare test sheet paper bin, in actual use, when a roll of test sheet paper is used up, a new roll of test sheet paper needs to be manually taken out from the spare test sheet paper bin for replacement and feeding, which affects the printing efficiency of the printer.

[0044] Referring to Figure 3 and Figure 4The accommodating cavity 11 is provided with a driving mechanism 8 for conveying the end of the test sheet printing paper 6 to the side of the paper inlet 121. The driving mechanism 8 comprises a plurality of telescopic rods 81, and each telescopic rod 81 is arranged on the fixed block 72. The telescopic rod 81 is fixedly connected to the slot opening of the installation slot 721 of the fixed block 72. A reset spring 811 is installed in the telescopic rod 81, and the reset spring 811 is arranged along the length direction of the telescopic rod 81.

[0045] With reference to Figure 3 , Figure 4 and Figure 5 , the driving mechanism 8 further comprises a fixing assembly 82 for fixing the end of the test sheet printing paper 6. The fixing assembly 82 corresponds to the telescopic rod 81 one by one, and the fixing assembly 82 is arranged on the telescopic end of the telescopic rod 81. The fixing assembly 82 comprises two clamping plates 821 rotatably connected to the side wall of the telescopic end of the telescopic rod 81, and a connecting spring 822 is fixedly connected between the two clamping plates 821.

In the present application, the adjusting piece 85 is arranged as an abutting triangular plate, and the bottom surface of the abutting triangular plate is fixedly connected to the printer head 12.

[0048] When the driving motor 41 drives the rotating shaft 3 to rotate, the installation roller 5 rotates together with the rotating shaft 3 under the action of the fixed block 72 and the connecting rod 71. When one of the installation rollers 5 rotates to the paper inlet 121, the first magnet block 83 on the telescopic rod 81 is attracted to the second magnet block 84 under the action of the second magnet block 84, and at the same time, the telescopic rod 81 is stretched against the elastic force of the reset spring 811, and the two clamping plates 821 move together with the telescopic end of the telescopic rod 81. Further, the test sheet printing paper 6 enters the paper inlet 121, and after the first magnet block 83 and the second magnet block 84 are attracted to each other, the abutting triangular plate is placed between the two clamping plates 821, so that the connecting spring 822 is in a stretched state, and the two clamping plates 821 cancel the clamping state of the test sheet printing paper 6.

Thus, when the rotating shaft 3 rotates again, the clamping plate 821 can compress the telescopic rod 81 under the abutting effect of the abutting arc-shaped plate 122, and further separate the first magnet block 83 and the second magnet block 84 from each other.

[0050] The principle of the embodiment of the present application is that the blocking cover 9 is opened, the adjusting nut 32 is adjusted, the installation roller 5 is taken out from the installation groove 721, then a plurality of test sheet printing papers 6 can be sequentially sleeved on the installation roller 5, the end of the test sheet printing paper 6 is fixed by the fixing assembly 82, then the blocking cover 9 is closed. Then the control knob 42 is pressed, the driving motor 41 is controlled to drive the rotating shaft 3 to rotate, so that the installation roller 5 rotates around the rotating shaft 3, and one of the installation rollers 5 rotates to the paper inlet 121 of the printer head 12, then under the adsorption effect of the first magnet block 83 and the second magnet block 84, the telescopic end of the telescopic rod 81 drives the end of the test sheet printing paper 6 to move to the side of the paper inlet 121, when the paper inlet 121 of the printer head 12 detects the test sheet printing paper 6, the printer head 12 can adsorb the test sheet printing paper 6 into the printer head 12, and when the first magnet block 83 and the second magnet block 84 are adsorbed to each other, the abutting triangular plate is arranged between the two clamping plates 821, so that the connecting spring 822 is in a stretched state, and then the two clamping plates 821 cancel the clamping state of the test sheet printing paper 6. Thus, the test sheet printing paper 6 is smoothly sucked into the printer head 12 through the paper inlet 121. When the test sheet printing paper 6 on the installation roller 5 is consumed, the driving motor 41 is controlled to drive the rotating shaft 3 to rotate, so that the test sheet printing paper 6 on the next installation roller 5 enters the printer head 12, thereby continuously adding the test sheet printing paper 6 into the printer.
