Description

Technical Field

[0001] The utility model belongs to the technical field of film sealing, in particular to a reagent card film sealing device. Background Art

[0002] The reagent card uses gel as the filler of the microcolumn gel card. The gaps between the gels only allow free red blood cells to pass through. The biochemical gel filtration technology, centrifugation technology and the antigen-antibody specific reaction of blood type serology are combined together for use in blood type serology tests. After filling, the reagent card can only be marketed after being sealed with aluminum foil to become a product. In the production process of the reagent card, how to seal the reagent card with aluminum-plastic film, that is, to use the aluminum-plastic film and the end plate at the open end of the reagent card for hot pressing to seal the opening of the reagent card is a very important process.

[0003] At present, the reagent card heat sealing device basically includes a mounting seat and a heat pressing plate. The mounting seat is provided with a storage slot for placing the reagent card, and the heat pressing plate is used for heat pressing and sealing the aluminum foil membrane and the end plate of the reagent card opening.

[0004] In order to improve the sealing effect of the aluminum foil diaphragm on the opening end of the reagent card, some reagent card sealing devices adopt the following two methods to heat press the aluminum foil diaphragm:

[0005] The first method is to use a larger area of aluminum foil to seal the reagent card opening, that is, the aluminum foil used is larger than the end plate of the reagent card opening, so that the aluminum foil can completely cover the end plate of the reagent card opening, and then cut off the excess part of the aluminum foil after heat sealing. This hot pressing packaging undoubtedly increases the heat sealing process and wastes the aluminum foil.

[0006] The second method is to set a positioning structure for limiting the position of the reagent card on the mounting seat of the heat sealing device. Figure 1 In the mounting seat structure shown, a receiving groove 81 for placing the reagent card is provided on the top surface of the mounting seat 8. In order to place the aluminum foil diaphragm for packaging directly opposite the end plate of the reagent card opening, a plurality of spring columns 82 are respectively arranged around each receiving groove 81. The enclosed area of the plurality of spring columns 82 corresponds to the end plate of the reagent card opening. After the reagent card is inserted into the receiving groove 81, the spring column 82 positions the end plate of the reagent card opening so that the aluminum foil diaphragm placed therein can directly face the end plate of the reagent card opening. When the hot pressing plate is pressed down, the aluminum foil diaphragm is hot pressed, and the reagent card is sealed, the spring column 82 is pressed down and moved down by the hot pressing plate. After the reagent card sealing operation is completed, the hot pressing plate is moved up, and the spring column 82 is reset under the action of elastic force. This method increases the complexity of the mounting seat structure and is inconvenient to take the reagent card. Utility Model Content

Specific embodiments

[0027] The present utility model will be described in detail below with reference to the attached drawings and in combination with embodiments.

[0028] A reagent card sealing film device includes a bottom plate 1, and a positioning block 2 and a bracket 3 arranged on the bottom plate 1. Among them, the bracket 3 is a portal bracket structure, the positioning block 2 is located at the center line of the portal frame 3, and a downward pushing element 6 is arranged at the top of the portal frame 3, and a pressing block 4 is arranged on its push rod. The downward pushing element 6 is a cylinder, a hydraulic cylinder or an electric push rod, etc. Preferably, the downward pushing element 6 is a double-axis cylinder to ensure the linearity of the push rod telescoping, so as to ensure the linearity of the up and down movement of the pressing block 4. An electric heating wire is arranged in the pressing block 4, and the electric heating wire is used to heat the pressing block 4. Its setting structure and principle are conventional technologies and will not be described in detail here.

[0029] The structure of the positioning block 2 is as Figure 2As shown in the figure, an insertion slot 21 corresponding to the reagent card is vertically opened downward on its top surface. And to facilitate the insertion of the reagent card into the insertion slot 21, the front end of the insertion slot 21 penetrates through the front side surface of the positioning block 2 (the side surface of the positioning block facing the operator), that is, the front end of the insertion slot 21 is open, and the rear end of the insertion slot 21 is closed to position the reagent card and the aluminum film. This structure facilitates the taking and placing of the reagent card in the insertion slot 21. The insertion slot 21 includes a positioning groove portion 212 and a receiving groove portion 211 arranged in sequence from top to bottom. Among them, the receiving groove portion 211 is used to hold the body of the reagent card (the part of the reagent card below the end plate at the opening end of the reagent card), and the positioning groove portion 212 corresponds to the end plate at the opening end of the reagent card, so that the positioning groove portion 212 and the receiving groove portion 211 form a stepped structure. The positioning groove portion 212 is used to support and position the end plate at the opening end of the reagent card, and the groove depth of the positioning groove portion 212 is greater than the sum of the thicknesses of the end plate at the opening end of the reagent card and the aluminum foil film, so as to realize the simultaneous positioning of the end plate at the opening end of the reagent card and the aluminum foil film by the positioning groove portion 212, so that the aluminum foil film placed in the positioning groove portion 212 can be directly opposite to the end plate at the opening end of the reagent card, facilitating the hot pressing and sealing operation of the aluminum foil film and improving the sealing effect of the aluminum foil film on the reagent card.

[0030] The structure of the pressing block 4 is as Figure 3 shown. A boss 41 is integrally formed on its bottom surface facing and matching the positioning groove portion 212. During heat sealing, the push rod of the downward pushing element 6 extends downward, driving the pressing block 4 to move downward, and the boss 41 is inserted into the positioning groove portion 212 to hot press the aluminum foil film, completing the sealing operation of the reagent card.

[0031] In the present utility model, a buffer structure 5 is provided between the push rod of the downward pushing element 6 and the pressing block 4. The buffer structure 5 includes a connecting plate 51 and four guide posts 52. Among them, the connecting plate 51 is installed on the push rod of the downward pushing element 6, and the four guide posts 52 are vertically arranged in a square shape on the top surface of the pressing block 4. The connecting plate 51 is provided with four guide holes corresponding to the four guide posts 52, and the guide posts 52 pass through the corresponding guide holes. A limit block is provided at the top of the guide posts 52 to prevent the guide posts 52 from falling off the connecting plate 51. A spring 53 is sleeved on each guide post 52 at the part between the connecting plate 51 and the pressing block 4, and both ends of the spring 53 abut against the connecting plate 51 and the pressing block 4. The setting of the buffer structure 5 prevents the pressing block 4 from having too large an impact on the aluminum-plastic film and the reagent card during the sealing of the reagent card, and prevents the reagent card from being damaged.

[0032] The operation process of the utility model is as follows: Insert the reagent card filled with gel into the card slot 21 from the front open end of the card slot 21 until the inner end of the end plate at the open end of the reagent card abuts against the rear end of the positioning groove part 212. At this time, the body part of the reagent card is located in the accommodating groove part 211, and the end plate at its open end is supported and positioned by the positioning groove part 212. Put the aluminum foil film piece corresponding to the size of the end plate at the open end of the reagent card into the positioning groove part 212, and the inner end of the aluminum foil film piece also abuts against the rear end of the positioning groove part 212. At this time, the aluminum foil film piece is facing the end plate at the open end of the reagent card. At the same time, the electric heating wire in the pressing block 4 heats up the pressing block to the preset temperature. The push rod of the pushing element 6 extends to drive the pressing block 4 to move downwards. The convex block 41 of the pressing block 4 enters the positioning groove part 212 to thermally press the aluminum foil film piece, thereby completing the sealing operation of the reagent card.

[0033] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
