Description

Technical Field

[0001] This utility model relates to the field of reagent kit production technology, specifically to an automatic sample addition and packaging device for African swine fever detection reagent kits. Background Technology

[0002] African swine fever (ASF) is an acute and highly contagious disease of domestic and wild pigs caused by the African swine fever virus. It spreads rapidly and has a high mortality rate, posing a huge threat to the pig farming industry. Therefore, pig farmers often keep ASF test kits at home for easy detection of the presence of the virus.

[0003] In the production process of African swine fever test kits, sample loading and packaging equipment is often used to add the reagents for testing to the kits. When adding reagents, some existing sample loading and packaging equipment often uses a filling machine to fill the kits because the amount of reagent added to each kit is fixed. However, when the filling machine is filling the kits, the O-rings in the filling machine's structure, which are used as sealing elements, are prone to chemical degradation and failure due to long-term contact with chemical substances such as reagents. This not only makes them difficult to replace but also easily results in excessive reagents being injected into the kits, causing production waste. Utility Model Content

[0004] The purpose of this invention is to provide an automated sample loading and packaging device for African swine fever test kits to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic sample loading and packaging device for African swine fever test kits, including an operating table, a mounting frame installed on the operating table, and a quantitative component for quantitative filling of reagents provided on the mounting frame;

[0006] The quantitative component includes a translational plate that moves in translational motion. Several baffles that limit the filling volume are provided on the translational plate. Each baffle is provided with a quantitative tube for quantitative filling of reagent. A sealing plate that temporarily seals the bottom end of the quantitative tube is attached to the bottom end of the tube.

[0007] The top of the mounting frame is equipped with a filling assembly for filling reagents;

[0008] The packaging component for the packaging reagent kit is mounted on the left side of the mounting bracket.

[0009] Preferably, the filling assembly includes several storage tanks, each storage tank having a liquid guide pipe at its bottom end, each liquid guide pipe having a liquid outlet block at its bottom end, and each liquid outlet block having a collection frame for temporary storage of reagents on its outer wall.

[0010] Preferably, the top of the baffle plate is provided with two sliding grooves, each of which is provided with a slider, and the bottom of the collection frame is connected to the two sliders.

[0011] Preferably, the top of the operating table is provided with a delivery component for moving the reagent kit.

[0012] Preferably, two limiting frames are installed on the outer wall of the translation plate to restrict the movement space of the translation plate.

[0013] Preferably, the side wall of the mounting frame is provided with an opening with the same width and height dimensions as the translation plate, through which the translation plate extends out of the mounting frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] The reagent can only be stored in a quantitative manner through the metering tube. After the metering tube is filled with reagent, the translation plate is controlled to move towards the front end, which drives the liquid baffle and metering tube to move until the bottom of the metering tube is separated from the sealing plate. At this time, the bottom of the liquid outlet block is blocked by the liquid baffle, and the opening at the bottom of the metering tube is opened, and the reagent will fall into the reagent kit, avoiding the situation of different reagent filling volume and reducing reagent waste.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 4This utility model provides a technical solution: an automatic sample loading and packaging device for African swine fever test kits, including an operating table 1. A T-shaped groove is provided at the top of the operating table 1. A material delivery component 2 for pushing the test kit is slidably installed in the T-shaped groove. A baffle is fixedly installed on the right side wall of the operating table 1 by welding. The material delivery component 2 includes a T-shaped slider adapted to the T-shaped groove. A mounting platform is installed at the top of the T-shaped slider by welding. A groove with the same length and width as the test kit is provided on the mounting platform. The test kit is placed in the groove on the mounting platform, and the T-shaped slider is pushed to slide in the T-shaped groove until the mounting platform is in contact with the baffle, so as to facilitate the horizontal movement of the test kit to the bottom of the quantitative component 7 for filling.

[0023] A mounting frame 3 is fixedly installed on the top of the operating table 1 by welding. A filling assembly is provided on the mounting frame 3. The filling assembly includes several storage tanks 4. Several through holes are provided on the top plate of the mounting frame 3. The storage tanks 4 are all installed in the through holes by insertion. The bottom outlet of the storage tank 4 is connected to a liquid guide tube 5 by threading. The bottom of the liquid guide tube 5 is welded with a liquid outlet block 14. The liquid outlet block 14 is provided with a through hole with the same inner diameter as the bottom opening of the liquid guide tube 5. The reagent in the storage tank 4 is discharged after passing through the liquid guide tube 5 and the storage tank 4.

[0024] The left side of the mounting frame 3 is equipped with a packaging component 6 for packaging the reagent kit. The packaging component 6 includes a fixing plate welded to the mounting frame 3. An electric push rod is installed at the bottom of the fixing plate, and a pressure plate is installed at the bottom of the electric push rod. Several grooves are evenly spaced at the bottom of the pressure plate. Rubber rings are glued to the inner walls of the grooves. The inner diameter of the rubber rings is two millimeters smaller than the diameter of the piston used at the opening of the reagent kit tube. The friction between the two is only enough to prevent the piston from falling downwards on its own, that is, to temporarily fix the piston in the groove at the bottom of the pressure plate. The electric push rod pushes the pressure plate and the piston downwards until the piston is inserted into the opening of the reagent kit tube. At this time, the friction between the opening of the reagent kit tube and the piston is... When the frictional force is greater than the frictional force between the piston and the rubber ring, controlling the retraction of the electric push rod can seal the piston and the reagent kit. The electric push rod is driven by an electric motor, and the rotating wheel is converted into a lead screw rotation through a worm gear transmission. The lead screw and nut mesh to drive the push rod to extend and retract linearly. That is, during use, the extension and retraction of the electric push rod is controlled by controlling the forward or reverse rotation of the electric motor. A switch is set on the side wall of the front end of the mounting bracket 3. The switch is connected to the motor through a circuit. The switch is a double-pole double-throw switch. The motor is a DC motor. When the switch is turned to the forward position, the A terminal is connected to the positive power supply and the B terminal is grounded, and the motor rotates forward. Conversely, the motor rotates in reverse (this is existing technology and will not be described in detail here).

[0025] The mounting frame 3 is equipped with a quantitative filling component 7 for reagents. The quantitative filling component 7 includes a sealing plate 8 welded and fixed to the mounting frame 3 and a translational plate 9 that can move horizontally. The mounting frame 3 has an opening with the same width and height as the translational plate 9. The translational plate 9 passes through this opening, penetrates one side wall of the mounting frame 3, and extends to one side. The sealing plate 8 consists of two horizontal plates and several baffles, which are welded and fixed to the two horizontal plates. Two limiting devices are welded and installed on the outer wall of the translational plate 9. A limiting frame 10 is provided for the movable space of the translation plate 9. Several liquid baffles 11 are also welded and installed on the translation plate 9. Both the upper and lower ends of the liquid baffles 11 are provided with through holes. A quantitative tube 12 is inserted into each through hole. A rubber ring is provided at the bottom end of the quantitative tube 12. The amount of medicine temporarily stored in the quantitative tube 12 is the amount of reagent required to be added to the reagent kit. The diameter of the quantitative tube 12 is the same as the diameter of the through hole on the liquid outlet block 14. A rubber ring is provided at the bottom end of the liquid outlet block 14 to fit the liquid baffles 11.

[0026] Two cross grooves are provided at the top of each baffle plate 11, and cross sliders 13 are slidably installed in each cross groove. The tops of the two cross sliders 13 located on the same baffle plate 11 are welded together to a collection frame 15. When a small amount of reagent seeps out from the gap between the liquid outlet block 14 and the baffle plate 11, it will be collected in the collection frame 15. A shielding plate is placed on the top plate of the collection frame 15 to facilitate the opening of the top opening of the collection frame 15 later to clean the reagent in the collection frame 15.

[0027] Working principle: When in use, place the reagent kit in the groove on the mounting platform, and push the T-shaped slider to slide in the T-shaped groove until the mounting platform is in contact with the baffle. Move the reagent kit directly under the quantitative component 7, and control the translation plate 9 to move towards the front end, which will drive the liquid baffle 11 and the quantitative tube 12 to move until the bottom of the quantitative tube 12 is out of contact with the sealing plate 8. At this time, the bottom of the liquid outlet block 14 is blocked by the liquid baffle 11, and the opening at the bottom of the quantitative tube 12 is opened, and the reagent will fall into the reagent kit. Then control the translation plate 9 to move in the opposite direction, and the quantitative tube 12 is covered again. At this time, the reagent in the storage tank 4 enters the quantitative tube 12 through the liquid guide tube 5 and the liquid outlet block 14. Then pull the reagent kit to move directly under the sealing component 6 for sealing.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
