[0001] This utility model relates to the field of specimen tube sealing technology, and in particular to a post-examination specimen tube sealing machine. Background Technology
[0002] After examination, the specimens are neatly arranged on the test tube rack, all of which are already opened. The tubes are of varying heights, and to avoid cross-contamination or spillage during handling, the tubes need to be sealed. Currently, there are two sealing methods: one is to use new test tube caps, which increases the number of steps, costs, and manpower; the other is to use plastic wrap for sealing, but this cannot accommodate tubes of different heights, can only cover the tallest tubes, and does not achieve a complete seal, still posing a risk of spillage. To address the above deficiencies, this application is proposed. Utility Model Content
[0003] The purpose of this invention is to provide a post-examination specimen tube sealing machine, which solves the problem that the current post-examination specimen sealing process is cumbersome and difficult to achieve a good sealing effect.

The adjusting rods are slidably mounted on the support frame, and the sealing execution components are connected to the adjusting rods. The support frame is mounted on the guide rods. During sealing, the support frame is moved towards the placement area, and the sealing film is positioned between the specimen tube and the sealing execution components. The displacement of the adjusting rods achieves the effect of contact between the sealing execution components and specimen tubes of different heights.
[0005] According to one embodiment of the present invention, the sealing film holder includes a fixed clamping piece and a movable clamping piece. The movable clamping piece and the fixed clamping piece are detachably connected. After the movable clamping piece is removed, the sealing film is placed on the fixed clamping piece.

[0006] According to one embodiment of the present invention, the sealing film clamping frame is mounted on the guide rod, and the sealing film clamping frame is connected to the support frame body, and the two move synchronously.
[0007] According to one embodiment of the present invention, a handle is connected to the support frame, and the support frame is moved up and down by operating the handle.
[0008] Optionally, a cylinder, electric cylinder, or electric guide rail can be installed and connected to the support frame to achieve automatic sealing.
[0009] According to one embodiment of the present invention, the guide rod is provided with a bottom limiting structure to limit the lowest position of the support frame or sealing film holder, and the lowest position should be lower than the specimen tube with the lowest height.
[0010] According to one embodiment of the present invention, the sealing execution component is a cylindrical structure, with a cutting blade provided at one open end of the cylindrical structure and a heat sealing structure provided inside the cylindrical structure.
[0011] Optionally, the cutting blade can be a thermal cutting blade, and the heat sealing structure can be a ring-shaped heat sealing blade or a hot air gun. When using a hot air gun, heat shrink film should be used.
[0012] According to one embodiment of the present invention, when using an annular heat-sealing knife, the heat-sealing structure is provided in several groups, and each group of heat-sealing structures corresponds to a specimen tube of different diameters.
[0013] According to one embodiment of the present invention, a core rod is provided on the support frame, and an adjusting rod is fitted on the core rod and can move along the core rod. The adjusting rod is connected to a spring.
[0014] According to one embodiment of the present invention, the post-examination specimen tube sealing machine further includes a sealing film, on which a number of sealing film pieces corresponding to the specimen tubes are provided, and the edges of the sealing film pieces are provided with an easy-tear structure, so that the sealing film pieces can be more easily removed from the sealing film.
[0015] The beneficial effects of this utility model are that by setting up a support frame, several adjusting rods and several sealing execution components, when sealing, the support frame is moved towards the placement area, the sealing execution components first contact the tallest specimen tube, and then the support frame continues to descend, the sealing execution components that have already contacted the specimen tube stop descending, until all sealing execution components are in contact with the specimen tube, and the sealing is completed. The sealing efficiency is high, the effect is good, and the risk of spillage is avoided after sealing. Attached Figure Description

[0023] The following description is only intended to disclose the present invention so that those skilled in the art can implement it. The embodiments in the following description are merely examples, and those skilled in the art will conceive of other obvious modifications. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other solutions that do not depart from the spirit and scope of the present invention.
[0024] Example 1:
[0025] Post-examination specimen tube sealing machine, such as Figure 1 It includes: a base 1, on which a placement area 5 for positioning and placing a test tube rack is provided. The placement area 5 is recessed to facilitate the positioning and placement of the test tube rack.
[0026] Guide rod 2, at least four sets of guide rod 2 are provided, all of which are connected to the base 1.
[0027] Two sets of sealing film clamping frames 6 are provided and are mounted on guide rods 2. The sealing film clamping frames 6 can move along the guide rods 2. The sealing film clamping frames 6 are equipped with clamps for clamping the sealing film 7. In this embodiment, the sealing film clamping frame 6 includes a fixed clamping piece 61 and a movable clamping piece 62. The movable clamping piece 62 and the fixed clamping piece 61 are detachably connected. After the movable clamping piece 62 is removed, the sealing film 7 is placed on the fixed clamping piece 61. The movable clamping piece 62 and the fixed clamping piece 61 can be connected by snap-fit or bolt. The two sets of sealing film clamping frames 6 achieve clamping of both ends of the sealing film 7. The tightness of the sealing film 7 is adjusted according to the elastic properties of the film material.
[0028] The sealing assembly includes a support frame 9, several adjusting rods 10, and several sealing execution components 13. The support frame 9 is mounted on guide rods 2 at all four corners and is located on the upper side of the sealing film clamping frame 6. The adjusting rods 10 can be configured as telescopic rods or slidably mounted on the support frame 9. In this embodiment, the adjusting rods 10 are slidably mounted on the support frame 9. A core rod 12 is provided on the support frame 9. The adjusting rods 10 are fitted onto the core rod 12 and can move along the core rod 12. The adjusting rods 10 are connected to springs 11.
[0029] like Figure 1The sealing film holder 6 is installed on the guide rod 2. The sealing film holder 6 is connected to the support frame 9 and the two move synchronously. The guide rod 2 is provided with a bottom limiting structure 16, such as a limiting block, to limit the lowest position of the support frame 9 or the sealing film holder 6. The lowest position should be lower than the specimen tube with the lowest height.
[0030] The sealing execution component 13 is connected to the adjusting rod 10.
[0031] During sealing, the support frame 9 is moved towards the placement area 5, and the sealing film is positioned between the specimen tube and the sealing execution component 13. The displacement of the adjusting rod 10 is used to achieve contact between the sealing execution component 13 and specimen tubes of different heights. Specifically, the sealing execution component 13 first contacts the taller specimen tube 4, then the support frame 9 continues to descend, and the sealing execution component 13, which has already contacted the specimen tube 4, stops descending and compresses the spring 11. Figure 2 The sealing process continues until all sealing components 13 are in contact with the specimen tube 4, thus completing the sealing.
[0032] After heat sealing, the sealing film on each specimen tube 4 is a separate film, that is, the sealing film has been separated from the whole sealing film 7. Alternatively, the whole sealing film 7 can be kept after sealing.
[0033] The sealing execution component 13 is selected according to the sealing method of the sealing film 7. The sealing film 7 can be sealed on the specimen tube 4 by heat sealing, heat shrinking or adhesive. When heat sealing is used, the sealing execution component 13 is equipped with a heat sealing knife. When heat shrinking is used, the sealing execution component 13 is equipped with a hot air gun or hot air outlet. When a hot air gun is used, a heat shrink film should be used. When adhesive is used, the sealing execution component 13 achieves sealing by pressing.
[0034] The support frame 9 can be moved manually or driven by a drive power module. When moving manually, handles 8 are connected to the left and right sides of the support frame 9. The support frame 9 can be moved up and down by operating the handles 8. When using a drive power module, a cylinder, electric cylinder or electric guide rail can be connected to the support frame 9 to achieve automatic movement.
[0035] Example 2:
[0036] Based on Example 1, in this example, the sealing film 7 is heat-sealed, such as... Figure 3 The sealing execution component 13 is a cylindrical structure, with a cutting blade 15 at one end of the opening and a heat sealing structure 14 inside the cylindrical structure.
[0037] Optionally, the cutting blade 15 can be configured as a thermal cutting blade.
[0038] The heat sealing structure 14 is configured as an annular heat sealing knife.
[0039] The heat-sealed module is powered by either a battery or an external AC power source.
[0040] Example 3:
[0041] Based on Example 2, such as Figure 4 When using an annular heat sealing knife, the heat sealing structure 14 is provided in several groups, and each group of heat sealing structures 14 corresponds to a specimen tube of different diameters.
[0042] The top wall of the cylindrical structure is provided with an annular groove, and the heat sealing knife is set on the inner wall of the groove. When the tube opening enters the annular groove, the heat sealing knife is used to achieve the heat sealing effect, reducing the influence of other heat sealing knives.
[0043] Example 4:
[0044] Based on any of the above embodiments, such as Figure 5 In this embodiment, the sealing film 7 is provided with a number of sealing film sheets 71 corresponding to the specimen tube. The edges of the sealing film sheets 71 are provided with an easy-tear structure, making it easier for the sealing film sheets 71 to detach from the sealing film 7.
[0045] Example 5:
[0046] Unlike in Example 1, as Figure 6 In this embodiment, the sealing film holder 6 is not installed on the guide rod 2, and it can be installed at a fixed height or with an adjustable height.
[0047] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functional and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations and modifications.
