The suction assembly 100 includes a pipeline 110 for drawing out gastric fluid, a controller 120 for controlling flow rate arranged on the pipeline 110, and a liquid outlet 130 arranged at the outlet of the pipeline 110; the controller 120 can be an adjustable pump, a flow meter, a valve, etc., mainly used for quantitatively controlling the delivery amount of gastric fluid, and for filling a certain volume of gastric fluid into a bottle 300 from the liquid outlet 130 in portions. The first conveying assembly 200 is used to convey the bottle 300 for containing gastric fluid at intervals. The second conveying assembly 400 is used to convey the bottle cap 500 that can be threadedly connected to the bottle mouth of the bottle 300 at intervals.

[0031] The capping assembly 600 includes a support platform 610, a bottle rotating rack 620 and a sealer 630; the bottle rotating rack 620 is rotatably mounted on the top of the support platform 610 and is close to the outlet of the first conveying assembly 200. The liquid outlet nozzle 130 and the outlet of the second conveying assembly 400 are staggered and located above the bottle rotating rack 620. The bottle rotating rack 620 is used to receive the bottles 300 sent by the first conveying assembly 200, and can rotate with the bottles 300 and then pause below the liquid outlet nozzle 130 or the outlet of the second conveying assembly 400; the sealer 630 is located above the outlet of the second conveying assembly 400 and is used to screw the bottle caps 500 onto the bottle mouths of the bottles 300.

[0032] The collecting platform 700 is arranged beside the supporting platform 610 and is used to place the bottles 300 covered with the bottle caps 500. The collecting platform 700 should have a height similar to that of the supporting platform 610 to facilitate the collection and placement of the bottles 300 filled with gastric juice and capped on the table.

[0033] More specifically, the first conveying assembly 200 includes a bottle bin 210, a bottle clamp 220 and a first conveyor belt 230; the interior of the bottle bin 210 has a space for placing bottles 300 one by one, and is provided with an opening 211 for allowing the bottles 300 to roll out; the bottle clamp 220 includes two guide plates 221 erected below the opening 211 of the bottle bin 210, and a rotating chuck 222 arranged therebetween, the guide plates 221 being arranged to have smooth arc-shaped edges from the top downward, and the two guide plates 221 being smaller than the radial width of the bottle 300, the rotating chuck 222 being vertically fixed with a rotating shaft 223, the rotating shaft 223 being driven by a first cylinder 224 to perform reciprocating rotation, the rotating chuck 222 rotating with the rotating shaft 223, and being able to partially block the opening 211 of the bottle bin 210 or open the opening 211; the entrance of the first conveyor belt 230 is arranged at the lower end of the arc-shaped edge of the guide plate 221. The rotating chuck 222 is a circular disk with a notch on its edge. When the rotating chuck 222 rotates to the position of the opening 211 of the bottle bin 210 , the notch opens the opening 211 .

[0034] When in use, the opening 211 can be opened only after the rotating chuck 222 is rotated, and the bottle 300 rolls out and then slides along the guide plate 221 to the entrance end of the first conveyor belt 230.

[0035] The first conveyor belt 230 includes a rectangular base 231, and motor-driven belts 232 arranged along two long edges of the base 231. There is a spacing between the two belts 232 for vertically placed bottles 300, and the outer side surfaces thereof are provided with a clamping protrusion 233. The conveyor belt of this structure is more conducive to transporting vertically placed bottles 300, so that subsequent filling and capping can be performed.

[0036] More specifically, the bottle rotating rack 620 includes a bottom plate 621, a top plate 622 and a central shaft 623 supported therebetween; the bottom plate 621 is located on the top of the support platform 610, and is provided with a plurality of receiving grooves 624 around the central shaft 623, and the side walls of the receiving grooves 624 located at the edge of the bottom plate 621 are through-set; a snap 625 is provided on the top plate 622 at positions corresponding to the receiving grooves 624, and the bottom plate 621 and the top plate 622 can rotate synchronously around the central shaft 623; after the bottle 300 is sent out from the outlet of the first conveying assembly 200, it enters the receiving groove 624 and is snapped in the snap 625. The central shaft 623 is fixedly connected to the bottom plate 621 and the top plate 622 at the same time, and its lower end passes through the bottom of the table surface of the support platform 610 and is driven to rotate by a motor. The receiving grooves 624 are evenly distributed around the central axis 623 , and the bottles 300 can rotate through the same angle after rotating with the bottle rotating rack 620 , so that different bottles 300 can be filled and capped in sequence.

[0037] More specifically, the sealer 630 includes a frame 631 mounted above the outlet of the second conveying assembly 400, a tightening motor 632 disposed at the top of the frame 631, a second cylinder 636 disposed in the frame 631, a lifting rod 633 disposed on the output shaft of the tightening motor 632, and a tightening sleeve 634 coaxially fixed to the lower end of the lifting rod 633; ​​the upper part of the lifting rod 633 is hollow and a waist hole 639 parallel to the axial direction is opened on the side wall, the output shaft of the tightening motor 632 is plugged into the upper end of the lifting rod 633 and A side-convex pin 635 is fixed to the side wall, and the pin 635 passes through the waist hole 639 and can slide along the waist hole 639; a connecting plate 637 is fixed to the end of the telescopic rod of the second cylinder 636, and a through hole is opened on the connecting plate 637 for passing the lifting rod 633, and the side wall of the lifting rod 633 is provided with two limiting convex rings 638 (one of the limiting convex rings in the figure is in the shape of a hexagonal nut and the other is in the shape of a cylinder), and the connecting plate 637 is located between the two limiting convex rings 638; tightening the sleeve 634 can match and cover the bottle cap 500.

[0038] Since the pin 635 is restricted in the waist hole 639, the lifting rod 633 can be used for upward and downward extension and can also rotate with the output shaft of the tightening motor 632. When in use, under the action of the second cylinder 636, the connecting plate 637 lifts the upper limiting convex ring 638 upward, and then lifts the lifting rod 633 and the tightening sleeve 634, so that the bottle cap 500 can slide onto the bottle mouth of the bottle 300; then, the connecting plate 637 presses the lower limiting convex ring 638 downward, and then the tightening sleeve 634 buckles the bottle cap 500, and then the tightening motor 632 is started to rotate several circles to tighten the bottle cap 500 to the bottle mouth.

[0039] The bottle cap 500 is made of plastic material, and its outer side is provided with strip-shaped vertical protruding teeth 510; the inner side wall of the tightening sleeve 634 is also provided with teeth matching the vertical protruding teeth 510. In this way, it can be ensured that the bottle cap 500 rotates effectively with the tightening sleeve 634.

[0040] More specifically, the second conveying assembly 400 includes a bottle cap bin 410, a second conveyor belt 420, a slideway 430 and a support plate 440; the bottle cap bin 410 is used to place the bottle caps 500; the second conveyor belt 420 is tilted, and its lower end is located at a low position in the bottle cap bin 410, and baffles 421 are provided on both sides thereof, and a through hole is opened on the upper part of one of the baffles 421; the slideway 430 is tilted, and its upper end is connected to the through hole position of the baffle 421; the support plate 440 is fixed to the lower end of the slideway 430, and has a hole that can pass through the bottle cap 500. The hole of the support plate 440 is opposite to the tightening sleeve 634 and the receiving groove 624, so as to ensure that the bottle cap 500 that slides down can cover the bottle mouth of the bottle 300, and ensure that the tightening sleeve 634 buckles the bottle cap 500.

[0041] The belt surface of the second conveyor belt 420 is provided with guide strips 422 at intervals, and the guide strips 422 are inclined across the second conveyor belt 420, and the lower end of the guide strips 422 is located on the side of the baffle plate 421 with a through hole. In this way, the bottle caps 500 can smoothly slide out of the second conveyor belt 420 and enter the slideway 430 during the conveying process.

[0042] It should be understood that all the above embodiments are illustrative rather than restrictive, and various modifications or variations made by those skilled in the art to the specific embodiments described above based on the concept of the present application should all be within the protection scope of the present application.
