Description

Technical Field

[0002] In vitro diagnostic reagents are equipment for immunological testing technology. They are easy to use and can be used to detect infectious diseases, autoimmune diseases, food safety, etc. They have a wide range of applications. Most in vitro diagnostic reagents come with matching membrane strips, and some reagents are also in fixed forms. During production and preparation, they need to be cut to separate the materials.

[0003] Common cutting processes are usually performed by cutting knives. When workers perform manual cutting, they can only rely on visual inspection to determine the cutting position of the material. The workers' judgment ability is limited, errors are prone to occur, and materials of different widths are easily obtained. The cutting quality is poor, resulting in material products that do not meet the use requirements. After cutting, materials of suitable sizes need to be screened, but manual screening is slow, and relatively small errors are not easy to judge, the work quality is limited, and the work efficiency is not high. In addition, during cutting, even if the visual judgment is more accurate, during cutting, because the cutter is mostly used for oblique cutting, when in contact with the material, it is easy to push the material to move, resulting in cutting errors due to the shaking of the material, resulting in reduced cutting quality.

[0033] In this embodiment, with the support of the workbench 1, each device works, and the position of the limit plate 5 is adjusted according to the cutting requirements. The adjusting screw 7 is controlled to rotate through the adjusting handle 6, so that the rotating adjusting screw 7 cooperates with the sliding groove 3 to provide itself with the power to move, so that the adjusting screw 7 drives the sliding frame 4 to move along the sliding groove 3, thereby driving the limit plate 5 to move through the sliding frame 4, and adjusting the distance between the limit plate 5 and the cutter 2 to meet the cutting requirements of the reagent material. When cutting, the material to be cut is placed on the workbench 1, and the cut end of the material is against the limit plate 5, and the material is cut by the cutter 2 so that the size of the material meets the requirements.

[0034] More specifically, after the cutting is completed, the material loses support, the sliding frame 4 is not in contact with the material and has no supporting capacity.

When passing through the second group of screening plates 10, the material with a cutting specification not greater than the requirement will fall from this group of screening ports 11. Finally, the material with a cutting specification greater than the requirement will move along the guide plate 8 to the end and fall, thereby screening the unqualified cutting materials.

[0049] In summary, when the overall device is in use or running:

[0050] When the device is used, according to the cutting requirements, the device is first adjusted, the position of the limit plate 5 is adjusted, and the adjusting screw rod 7 is controlled to rotate through the adjusting handle 6, so that the rotating adjusting screw rod 7 cooperates with the sliding groove 3 to provide itself with the power for moving, wherein the adjusting screw rod 7 cooperates with the threaded groove 22 through the threaded rod 21 part, and when the adjusting screw rod 7 rotates, the threaded rod 21 cooperates with the threaded groove 22, so that the threaded rod 21 moves along the threaded groove 22, thereby providing power, and the rotating rod 20 part of the adjusting screw rod 7 cooperates with the sliding frame 4 through the cooperation of the rotating ring 23 and the rotating groove 24, and the rotating ring 23 rotates freely in the rotating groove 24 and is restricted by the rotating groove 24, so that the rotating rod 20 and the sliding frame 4 are connected as a whole and can rotate freely at the same time, so that the adjusting screw rod 7 drives the sliding frame 4 to move, so that the adjusting screw rod 7 drives the sliding frame 4 to move along the sliding groove 3, and through the linkage cavity 25 to lift the space, when the adjusting screw rod 7 at one end is controlled to rotate, The rotating rod 20 will drive the corresponding transmission wheel 26 to rotate, and the transmission wheel 26 drives the transmission wheel 26 at the other end to rotate through the transmission belt 27, so that the two rotating rods 20 rotate synchronously, so that the two adjusting screw rods 7 are consistent, so as to ensure the stability of the sliding frame 4, and then the limit plate 5 is driven to move through the sliding frame 4 to adjust the distance between the limit plate 5 and the cutter 2. When the sliding frame 4 moves along the sliding groove 3, the scale ruler 18 will move with the sliding frame 4 and move along the space groove 19. The position of the limit plate 5 is judged by the value on the scale ruler 18 to meet the cutting requirements of the reagent material. Then, according to the cutting requirements, the screening plate 10 with the appropriate size of the screening port 11 is installed in the installation port 9, wherein the screening port 11 of the first group of screening plates 10 is slightly smaller than the required size. Finally, the collection box 28 is placed below the second group of screening ports 11, and the two groups of recovery boxes 29 are respectively arranged below the first group of screening ports 11 and at one end of the guide plate 8 to complete the preparation for work.

[0051] When cutting, the material to be cut is placed on the workbench 1, and the cut end of the material is against the limit plate 5. At this time, the distance between the limit plate 5 and the cutter 2 meets the cutting requirements, so the part of the material exceeding the cutter 2 meets the use requirements, and the cutter 2 is used to cut the material on the workbench 1. The cutter 2 cooperates with the workbench 1 to cut off the part of the material exceeding the cutter 2. When cutting, the cutter 2 moves, and the cutter 2 cooperates with the pressure frame 13 through the pressure rod 16. The cutter 2 drives the pressure rod 16 to move, and the pressure rod 16 rotates and moves in the pressure groove 17 to apply force to the pressure frame 13. Under the support of the bracket 12, as the cutter 2 moves downward, the pressure frame 13 moves downward along the bracket 12, and the pressure frame 13 drives the pressure plate 14 to move downward through the pressure spring 15.

After the cutting is completed, the material loses support, the sliding frame 4 is not in contact with the material, and has no supporting capacity. Under the action of gravity, the material falls, passes through the sliding frames 4, falls on the guide plate 8, and then slides along the guide plate 8. When the material passes through the first group of screening plates 10, the material with a cutting specification smaller than the requirement will fall from the screening port 11 of this group and fall into the recycling box 29. The remaining material continues to move. When passing through the second group of screening plates 10, the material with a cutting specification not larger than the requirement will fall from the screening port 11 of this group and fall into the collection box 28.
