DETAILED DESCRIPTION

[0028] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0029] like Figure 1-5As shown, a liquid filling machine of the present invention comprises a machine body 1, a transmission slot 11 is transversely arranged on the upper side of the machine body 1, a transmission belt 12 is rotatably mounted in the transmission slot 11, a processing slot 13 connected to the transmission slot 11 is arranged on the upper side of the machine body 1, a rotating plate 14 is rotatably mounted in the processing slot 13, a plurality of notches 15 are arranged on the outer surface of the rotating plate 14, a filling mechanism, a cover mechanism and a cover screwing mechanism are arranged on the upper side of the machine body 1, the filling mechanism comprises a top rod 2 slidably mounted on the upper side of the machine body 1, a support frame 21 is arranged on the upper side of the top rod 2, and filling tubes 2 are arranged on both sides of the support frame 21. 2. The two filling tubes 22 are equipped with a liquid supply component. The inner walls of the lower sides of the two filling tubes 22 are each provided with a groove 23. The opening of the groove 23 is provided with a sealing bag 24. The outer surfaces of the two filling tubes 22 are both connected with an air supply pipe 25 connected with the groove 23. An inner cavity 3 is provided on the upper side of the body 1. A rebound mechanism is provided in the inner cavity 3. A slider 31 is provided on the upper side of the rebound mechanism. The slider 31 is slidably and sealably assembled in the inner cavity 3. An air delivery pipe 32 connected with the two air supply pipes 25 is provided on the inner wall of the upper side of the inner cavity 3. A linkage mechanism matching the support frame 21 is provided on the upper side of the slider 31.

[0030] When it is necessary to fill the mouthwash, the empty bottle can be placed on the conveyor belt 12 on the left. Under the action of the conveyor belt 12, the empty bottle is driven to move to the side of the rotating plate 14 until the empty bottle is in close contact with the rotating plate 14, and the empty bottle enters the plurality of notches 15 in sequence. At this time, the rotating plate 14 rotates, driving the empty bottle to rotate and move into the processing groove 13. When the empty bottle is located at the lower side of the filling mechanism, the push rod 2 moves downward, and the push rod 2 drives the two filling tubes 22 to move downward through the support frame 21 until the two filling tubes 22 extend into the two empty bottles respectively, and then the liquid supply component starts to work, and the mouthwash is injected into the empty bottle through the two filling tubes 22. After the filling of the mouthwash is completed, the push rod 2 moves upward, drives two filling tubes 22 to move upward through the support frame 21, until the filling tubes 22 move out of the empty bottles, then the rotating plate 14 continues to rotate, the rotating plate 14 drives the bottles after filling to move to the lower side of the upper cover mechanism, the upper cover mechanism seals the cap on the bottle, the rotating plate 14 continues to move, drives the upper cover to move to the lower side of the cap screwing mechanism, then the cap screwing mechanism tightens the cap on the bottle, the rotating plate 14 rotates again, and then moves the bottles after filling and capping out of the processing tank 13, until the bottles move to the conveyor belt 12 of the right conveyor tank 11, the conveyor belt 12 on the right moves the bottles after filling out and moves them to the next processing equipment;

[0031] During the continuous downward movement of the support frame 21, the support frame 21 drives the slider 31 in the inner cavity 3 to move downward through the linkage mechanism. During the downward movement of the slider 31, the rebound mechanism begins to compress. During the movement of the slider 31, a negative pressure state exists in the upper space of the inner cavity 3. The gas in the grooves 23 in the two filling tubes 22 is extracted through the air pipe 32 and the two air supply pipes 25, which drives the sealing bag 24 to shrink. After the filling tube 22 moves downward to the limit position, the sealing bag 24 shrinks completely, thereby canceling the sealing of the filling tube 22. This makes it easier for mouthwash to pass through the filling tube 22 and enter the bottle. When the filling is completed, the filling tube 22 and the support frame 21 gradually cancel the pressure of the linkage mechanism on the slider 31 during the upward movement, so that the rebound mechanism begins to stretch, driving the slider 31 to move upward in the inner cavity 3, thereby injecting the gas on the upper side of the inner cavity 3 into the two grooves 23 through the two air supply pipes 25 and the air delivery pipe 32, driving the two sealing bags 24 to expand, and then sealing the filling tube 22, thereby preventing the residual mouthwash in the filling tube 22 from dripping downward.

[0032] The rebound mechanism includes a spring 33 disposed in the inner cavity 3 , and the upper and lower ends of the spring 33 are connected to the slider 31 and the lower inner wall of the inner cavity 3 respectively.

[0033] When the slider 31 moves downward in the inner cavity 3, the spring 33 is compressed. When the pressure on the slider 31 is removed, the slider 31 is pushed back upward under the action of the spring 33 being stretched.

[0034] The linkage mechanism includes a contact rod 34 , which is connected to the upper surface of the slider 31 . An extension opening 35 is provided on the upper inner wall of the inner cavity 3 . The upper end of the contact rod 34 passes through the extension opening 35 and matches the position of the support frame 21 .

[0035] When the support frame 21 moves downward, it presses the contact rod 34 , driving the contact rod 34 to move downward, thereby driving the slider 31 to move downward in the inner cavity 3 .

[0036] A buffer block 36 matching the contact rod 34 is provided on the lower side of the support frame 21. When the support frame 21 moves downward, the buffer block 36 contacts the contact rod 34, driving the contact rod 34 to move downward.

[0037] The upper cover mechanism includes a transmission member 4, a fixing plate 41 connected to the transmission member 4 is provided on the upper side of the body 1, a fixing frame 42 is provided on the upper side of the fixing plate 41, the fixing plate 41 is provided with a pressure hole 43 connected to the inside of the transmission member 4, an electric telescopic rod 44 is installed on the upper side of the fixing frame 42, and a pressure block 45 is installed at the output end of the electric telescopic rod 44 through the fixing plate 41, and the pressure block 45 matches the position of the pressure hole 43.

[0038] The bottle cap can move toward the rotating plate 14 under the action of the transmission member 4, and move to the lower side of the pressing hole 43. At this time, the electric telescopic rod 44 begins to extend, driving the pressing block 45 to move downward, pass through the pressing hole 43, and squeeze the bottle cap on the bottle.

[0039] The cap screwing mechanism includes a hydraulic rod 5 arranged on the upper side of the machine body 1, the output end of the upper side of the hydraulic rod 5 is equipped with a mounting plate 51, the mounting plate 51 is rotatably equipped with a rotating shaft 52, a motor 53 is provided on the upper side of the mounting plate 51 and is transmission-connected to the rotating shaft 52, a rotating member 54 is installed at the lower end of the rotating shaft 52, and a fixing clamp 55 is installed on the lower side of the rotating member 54.

[0040] When the bottle moves to the lower side of the rotating member 54 after filling, the hydraulic rod 5 starts to contract, driving the rotating member 54 to move downward, and the rotating member 54 contacts the upper side of the bottle, and then clamps the bottle cap through the fixing clamp 55. Then the motor 53 starts to work, driving the rotating shaft 52 to start rotating, thereby driving the fixing clamp 55 to rotate, and the bottle cap can be tightened on the bottle.

[0041] The liquid supply assembly includes a liquid storage tank 6 disposed on the outer surface of the body 1, and two filling tubes 22 are both inserted into the liquid storage tank 6 and equipped with a pump body. When the mouthwash is injected into the liquid storage tank 6, the pump body starts to work and the mouthwash in the liquid storage tank 6 is drawn out through the filling tubes 22.

[0042] The outer surface of the groove 23 is provided with an arc strip 61 that matches the position of the rotating plate 14. The design of the arc strip 61 can limit the bottle moving in the processing groove 13 and improve stability.

[0043] The inner wall at the lower side of the inner cavity 3 is provided with a pressure relief hole 62. The design of the pressure relief hole 62 can keep the lower side of the inner cavity 3 connected with the outside world, and keep the air pressure at the lower side of the inner cavity 3 balanced.
