[0019] See also Figure 1-4 , the utility model provides an embodiment: an automated sampling device for food sampling, comprising a frame 1;

[0020] The upper end of the frame 1 is symmetrically provided with movable grooves 2, a mounting plate 3 is fixedly installed at the rear side of the frame 1, and a conveying assembly is arranged in the two sets of movable grooves 2. A slide groove 11 is arranged in the mounting plate 3, a screw rod 12 is rotatably installed in the slide groove 11, a second motor 13 is fixedly installed at the rear end of the screw rod 12, a bracket 14 is slidably installed in the slide groove 11, the lower end of the bracket 14 is connected to the screw rod 12 through a threaded sleeve, and a sampling assembly is arranged at the upper end of the bracket 14. The device moves the bottled food through the conveying assembly, and drives the screw rod 12 to rotate by the second motor 13 to move the bracket 14 forward, and moves the sampling assembly on the bracket 14 to the upper end of the bottled food, so as to facilitate the sampling inspection of the bottled food;

[0021] Further, the conveying assembly includes a first motor 4 and four sets of rotating shafts 5. The first motor 4 is fixedly installed in the left end of the frame 1. The four sets of rotating shafts 5 are rotatably installed in the left and right ends of the two sets of movable grooves 2. Two sets of chain plates 6 are installed on the four sets of rotating shafts 5. Multiple sets of limiting plates 7 are installed on the outer walls of the two sets of chain plates 6. Synchronous wheels 8 are fixedly installed at the lower ends of the two sets of rotating shafts 5 in the left ends of the two sets of movable grooves 2. Synchronous belts 9 are sleeved on the two sets of synchronous wheels 8. The output shaft of the first motor 4 is fixedly connected to the synchronous wheel 8 on the front side of the left end of the frame 1. This structure drives the two sets of synchronous wheels 8 and the synchronous belts 9 through the output shaft of the first motor 4. The four sets of rotating shafts 5 and the two sets of chain plates 6 rotate, and when the two sets of chain plates 6 rotate, the bottled food is limitedly conveyed through the multiple sets of limiting plates 7, so that the bottled food is orderly arranged and conveyed to the next stage and it is convenient for the sampling assembly to sample the bottled food.

[0022] Furthermore, the multiple groups of limiting plates 7 on the outer walls of the two groups of rotating shafts 5 are arranged in pairs, and the opposite sides of the two groups of limiting plates 7 are arc-shaped. This structure is convenient for the multiple groups of limiting plates 7 to limit the bottled food in pairs according to the positions and shapes of the multiple groups of limiting plates 7, thereby avoiding shaking of the bottled food during transportation.

[0023] Furthermore, the sampling inspection component includes an electric telescopic rod 15 and an air pump 16, the electric telescopic rod 15 is fixedly installed on the upper end of the bracket 14, the air pump 16 is fixedly installed on the lower end of the electric telescopic rod 15, and a dropper 17 is fixedly installed on the lower end of the air pump 16, two groups of fixed plates 18 are fixedly installed on the lower side of the front end of the bracket 14, and the lower ends of the two groups of fixed plates 18 are hingedly installed with sealing plates 19, and tooth plates 20 are symmetrically installed on the left and right sides of the air pump 16, and gears 21 are fixedly installed at the hinges between the upper ends of the two groups of sealing plates 19 and the two groups of fixed plates 18, and the two groups of tooth plates 20 are meshed with the two groups of gears 21. When the bracket 14 moves forward, the electric telescopic rod 15 extends the air pump 16 and the dropper 17 downward and inserts them into the bottled food, and after extracting a certain amount of liquid, the electric telescopic rod 15 drives the air pump 16 and the dropper 17 to reset upward, and the two groups of gears 21 drive the two groups of tooth plates 20 to move and close the two groups of sealing plates 19, thereby sealing the lower end of the dropper 17.

[0024] Furthermore, two sets of sealing plates 19 hingedly connected at the lower ends of the two sets of fixing plates 18 are respectively provided with a block 22 and a slot 23 on opposite sides, and the block 22 is movably inserted in the slot 23. This structure improves the sealing performance of the two sets of sealing plates 19 after closing by inserting the block 22 in the slot 23.

[0025] Furthermore, anti-skid pads 10 are glued to the opposite sides of the multiple sets of limiting plates 7, and the multiple sets of anti-skid pads 10 are all made of rubber material. This structure increases the anti-skid and tightness of the multiple sets of limiting plates 7 and the bottled food when the multiple sets of limiting plates 7 are in contact with the outer wall of the bottled food through the anti-skid pads 10 glued to the multiple sets of limiting plates 7.

[0026] Working principle: When sampling bottled food, Figure 2 , Figure 3 and Figure 4 As shown, the first motor 4 is started, and the output shaft of the first motor 4 rotates to drive the two sets of synchronous wheels 8 and the synchronous belt 9 to rotate, and the rotation of the two sets of synchronous wheels 8 drives the four sets of rotating shafts 5 and the two sets of chain plates 6 to rotate, and the rotation of the two sets of chain plates 6 drives the multiple sets of limiting plates 7 to move, and the bottled food enters through the left ends of the two sets of chain plates 6, and the two sets of chain plates 6 drive the multiple sets of limiting plates 7 to convey the bottled food, and the second motor 13 is started, and the output shaft of the second motor 13 drives the screw 12 to rotate and drive the bracket 14 to slide in the slide groove 11, and when the front end of the bracket 14 moves to the upper side of the bottled food, the electric telescopic rod 15 is started, and the electric telescopic rod 15 moves the air pump 16 and the dropper 17 downward, and the air pump 16 and the dropper 17 are moved downward. When 7 moves downward, it drives two sets of toothed plates 20 to rotate two sets of gears 21. The rotation of the two sets of gears 21 drives several sets of sealing plates 19 to rotate and open at the lower ends of the two sets of fixed plates 18. When the dropper 17 is inserted into the bottled food, the liquid is extracted under the action of the air pump 16. Then the electric telescopic rod 15 reaches the air pump 16 and the dropper 17 to reset upward. When the air pump 16 and the dropper 17 are reset upward, the two sets of sealing plates 19 are closed through the two sets of gears 21 and the two sets of toothed plates 20, so as to seal and protect the liquid in the dropper 17. Then the output shaft of the second motor 13 drives the screw 12 to rotate to move the bracket 14 backward to dock with the inspection device. The above is the entire working principle of the utility model.
