Description

Technical Field

[0001] The invention relates to the technical field of test strip cutting, in particular to a test strip cutting device for a diagnostic kit. Background Art

[0002] The test strip in the diagnostic kit is a commonly used testing tool used to detect specific chemicals or biological molecules in the sample. It uses specific compounds or molecules such as proteins, enzymes, antibodies, etc. to react specifically with the substance to be tested to achieve the target analysis. Test strips are usually long strips made of paper or other adsorbent materials. The thickness of test strips made of different materials is different, and the width of the test strips is also different. The most commonly used test strips in the world are 76 mm and 90 mm in width, while the width of test strips in my country is 80 mm and 100 mm.

[0003] In the prior art, a Chinese patent with publication number "CN117798997A" discloses a test strip cutting device for a diagnostic kit, which shields the test strip from both sides with a main strip and a secondary strip, and presses the test strip with a pressure strip, so that multiple stacked test strips are pressed, so that the test strips will not fall over or stagger during the cutting process, thereby greatly improving the stability of the test strip cutting process, and solving the existing problem that due to the narrow width of the test strip, multiple test strips will be pressed and fall over or stagger during the cutting process, thereby affecting the uniformity of the cutting position of the test strip.

[0004] The test strip cutting device in the existing diagnostic kit is a tool specially used to cut the test strips into appropriate lengths. When cutting the test strips, there are two ways of cutting. One cutting method is to stack the test strips together and use a cutter to complete the cutting of the test strips. As in the scheme described above, the test strips need to be manually stacked and installed on the cutting device. Due to the uncertainty of manual labor, the stacked test strips may be offset, which will make the cut test strips unusable. Another cutting method is not to stack the test strips, but to cut a single test strip with a cutter. However, most of the existing cutting devices cannot achieve cutting of test strips of different widths, and cannot guarantee the accuracy of the position and direction of the test strips during transportation, thereby causing damage to the test strips. Therefore, the present invention proposes a test strip cutting device for a diagnostic kit to solve the above-mentioned problems. Summary of the invention

[0044] Working principle:

[0045] When in use, the driving motor 9 drives the driving gear 12 on the rotating shaft 10 to rotate, and the driven gear 13 is meshed with the driving gear 12, so that the driven gear 13 rotates on the inner side of the side plate 2 through the rotating shaft 10. At this time, the driving gear 12 and the driven gear 13 rotate in the same direction, and the mounting block 14 and the lifting block 18 on the driving gear 12 and the driven gear 13 will synchronously follow the driving gear 12 and the driven gear 13 to rotate, and the fixed block 23 installed on the lifting block 18 through the rotating shaft 22 and the cutter 3 on the fixed block 23 will be in a lifting state through the limit frame 5. During this process, the rotating shaft 22 rotates with the lifting block 18, and the fixed block 23 is rotationally connected to the rotating shaft 22. The cutter 3 will not rotate synchronously with the lifting block 18 through the limit of the limit frame 5, and the cutter 3 on the driving gear 12 and the driven gear 13 will move synchronously inward, thereby completing the cutting of the test strip;

[0046] When the width of the test strip needs to be adjusted, the threaded rod 20 in the adjustment assembly is rotated to utilize the bearing 19 on the lifting plate 16 and the limit of the lifting slot 15, so that the lifting plate 16 in the lifting slot 15 moves upward, and the position of the lifting block 18 is adjusted by the lifting rod 17 on the lifting plate 16, and the cutter 3 on the lifting block 18 is adjusted, so as to realize the cutting of test strips of different widths;

[0047] When the driving gear 12 rotates, the auxiliary gear 25 is meshed with the driving gear 12, and the auxiliary gear 25 rotates inside the bracket plate 1 through the mounting shaft 24, and the circular plate 26 mounted on the auxiliary gear 25 rotates synchronously, and the fitting plate 35 on the circular plate 26 contacts the uncut test strip, thereby realizing the automatic conveyance of the test strip.

[0048] When test strips of different thicknesses are transported, the annular block 30 is driven to slide on the mounting rod 27 by the bidirectional push rod 29, and the connecting tube on the bonding plate 35 is pushed to move outward or inward by the rotating rod 32 on the annular block 30, so that the distance between the bonding plate 35 and the conveying plate 6 can be adjusted to make the bonding plate 35 contact with the test strips on the conveying plate 6, thereby realizing the transportation of test strips of different thicknesses. At the same time, the position and direction of the test strip can be ensured to be accurate when cutting the test strip, thereby avoiding damage to the test strip and poor cutting effect.

[0049] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
