[0037] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings to further illustrate the present invention.

[0038] First, combine Figures 1 to 4 The sealing mechanism of the double-head filling production line according to the embodiment of the present invention is described, which is used for sealing filling bottles and has a wide range of application scenarios.

[0039] like Figures 1 to 4 As shown, the sealing mechanism of the double-head filling production line of the embodiment of the utility model includes: a conveyor line 1, a cap feeding module 2, a first capping module 3 and a second capping module 4.

[0040] Specifically, if Figures 1 to 4As shown, in this embodiment, the conveyor line 1 vertically conveys filled bottles 5; the capping module 2 is connected to the first capping module 3, and the first capping module 3 and the second capping module 4 are arranged above the conveyor line 1; the capping module 2 outputs the bottle cap 66 and conveys it to the first capping module 3. The first capping module 3 initially fastens the bottle cap 6 to the bottle mouth of the filled bottle 5, ensuring the initial positioning of the bottle cap 6. The second capping module 4 then compacts the bottle cap 6 at the bottle mouth for a second time, further ensuring the sealing and stability of the bottle cap 6. The dual capping modules effectively ensure the tight fit of the bottle cap 6, improving the packaging quality. A highly automated production process is formed between the modules. The continuous and orderly operation method reduces manual intervention and significantly improves production efficiency.

[0041] Further, if Figures 1 to 4 As shown, in this embodiment, the cap feeding module 2 includes: a support base 21 and a vibration plate 22; the support base 21 supports and fixes the vibration plate 22; the vibration plate 22 is connected to the first capping module 3, and the vibration plate 22 vibrates and outputs the bottle caps 6 to the capping module, thereby realizing the automatic and orderly output and delivery of the bottle caps 6, and has strong adaptability.

[0042] Further, if Figures 1 to 4 As shown, in this embodiment, the first capping module 3 includes: a first mounting frame 31, a capping cylinder 32, a material receiving plate 33, a pair of supporting plates 34 and a pair of torsion springs 35;

[0043] The first mounting frame 31 is fixed on the conveyor line 1 to achieve overall support and stability of the first capping module 3;

[0044] The capping cylinder 32 and the receiving plate 33 are fixed on the first mounting frame 31;

[0045] The receiving plate 33 is connected to the output end of the cap feeding module 2 to receive the bottle caps 6 output by the cap feeding module 2. The receiving plate 33 is provided with a cap outlet hole, which is adapted to fit the bottle caps 6. The bottle caps 6 fall from the cap outlet hole and are output to the bottle mouths of the filling bottles 5.

[0046] A pair of supporting plates 34 are respectively arranged on the receiving plate 33 through a pair of torsion springs 35 and are respectively arranged on opposite sides of the cap outlet hole. The supporting plates 34 support the bottle caps 6 located in the cap outlet hole and can effectively prevent the bottle caps 6 from falling immediately after reaching the cap outlet hole. The torsion springs 35 can realize the support, flipping and reset of the supporting plates 34.

[0047] The capping cylinder 32 is opposite to the capping hole to ensure that the capping cylinder 32 accurately acts on the corresponding bottle cap 6. The output end of the capping cylinder 32 can fix the pressure plate, thereby increasing the action area on the bottle cap 6 and reducing stress concentration.

[0048] When the bottle cap 6 is fastened to the bottle mouth of the filling bottle 5, the capping cylinder 32 extends and presses the bottle cap 6 located at the cap outlet hole downward. The bottle cap 6 is subjected to the downward squeezing force, which drives a pair of supporting plates 34 to flip open, thereby opening the cap outlet hole, and the bottle cap 6 is pressed and fastened to the bottle mouth. After the fastening is completed, the capping cylinder 32 retracts, and the supporting plates 34 are reset under the action of the torsion spring 35, waiting for the next pressing of the bottle cap 6.

[0049] Further, if Figures 1 to 4 As shown, in this embodiment, the first capping module 3 further includes: a clamping cylinder 36, which is fixed on the first mounting frame 31. The clamping cylinder 36 clamps and fixes the filling bottle 5 to ensure that it does not move or shake during the capping process, which helps to improve the accuracy and stability of the capping and ensure that the bottle cap 6 can be accurately fastened to the bottle mouth.

[0050] Further, if Figures 1 to 4 As shown, in this embodiment, the first capping module 3 further includes: a pair of positioning cylinders, which are arranged on the side walls of the conveyor line 1. The conveyor line 1 conveys the filled bottles 5 between the pair of positioning cylinders, and the pair of positioning cylinders extend to position the filled bottles 5. For the convenience of description, the pair of positioning cylinders are divided into a first positioning cylinder 37 and a second positioning cylinder 38. The first positioning cylinder 37 is closer to the second capping module 4 than the second positioning cylinder 38. During use, the first positioning cylinder 37 extends first. When the filled bottle 5 is conveyed to contact the first positioning cylinder 37, the second positioning cylinder 38 extends to block the subsequent bottle cap 6 and prevent it from moving forward. At the same time, it cooperates with the first positioning cylinder 37 to achieve positioning of the filled bottle 5 for the capping operation.

[0051] Further, if Figures 1 to 4 As shown, in this embodiment, the second capping module 4 includes: a second mounting frame 41, a pair of height adjustment components, a conveyor belt 42 and a pair of side plates 43;

[0052] The second mounting bracket 41 is fixed on the conveyor line 1;

[0053] The height adjustment assembly is arranged on the second mounting frame 41;

[0054] A pair of side plates 43 are respectively fixed on both sides of the conveyor belt 42 to achieve installation and fixation of the conveyor belt 42;

[0055] The conveyor belt 42 is connected to a pair of height-adjusting components via a pair of side plates 43. The conveyor belt 42 is tilted and suspended above the conveyor line 1 via the pair of height-adjusting components. The distance between the conveyor belt 42 and the conveyor line 1 gradually decreases along the conveying direction of the conveyor line 1. The conveyor belt 42 performs secondary compaction on the bottle caps 6 at the bottle mouths. The conveyor belt 42 adopts the existing, tilted arrangement of the conveyor belt 42, so that when the filled bottles 5 are conveyed, the bottle caps 6 receive gradually increasing downward pressure, thereby ensuring that the bottle caps 6 are tightly fastened to the bottle mouths. This secondary compaction mechanism helps to improve the packaging quality.

[0056] A pair of height adjustment components are used to adjust the height of the conveyor belt 42 to adapt to filling bottles 5 and bottle caps 6 of different specifications, and ensure that the conveyor belt 42 can generate appropriate pressure when compacting the bottle caps 6.

[0057] Further, if Figures 1 to 4 As shown, in this embodiment, the height adjustment assembly includes: a screw 45, a fixing plate 46, a nut 47 and a hand wheel 48;

[0058] Both ends of the fixing plate 46 are fixedly connected to a pair of side plates 43;

[0059] The nut 47 is provided on the second mounting bracket 41 to provide a stable support point for the screw 45;

[0060] The two ends of the screw rod 45 are connected to the fixing plate 46 and the hand wheel 48 respectively. The screw rod 45 passes through the nut 47 and the second mounting bracket 41 and is screwed to the nut 47.

[0061] When the inclination needs to be adjusted, the hand wheel 48 is manually rotated to drive the screw rod 45 to move up and down, thereby driving the fixing plate 46 and the conveyor belt 42 to move up and down.

[0062] Working principle: The vibration plate 22 vibrates and outputs the bottle cap 6 to the receiving plate 33. When the conveyor line 1 conveys the filled bottle 5 to the bottom of the receiving plate 33, a pair of positioning cylinders are positioned, and at the same time, the clamping cylinder 36 clamps the filled bottle 5, and the capping cylinder 32 squeezes the bottle cap 6 downward to buckle it to the bottle mouth. After the buckling is completed, the positioning cylinder and the clamping cylinder 36 are released, and the conveyor line 1 continues to convey the filled bottle 5 to the bottom of the conveyor belt 42 to buckle and compact the bottle cap 6.

[0063] Above, refer to Figures 1 to 4 This article describes the sealing mechanism of a dual-head filling production line according to an embodiment of the present invention. It employs dual capping to achieve efficient and precise capping, improving packaging quality. Furthermore, each module is highly automated, reducing manual intervention and significantly improving production efficiency. Furthermore, the system is highly adaptable and can flexibly handle different sizes of bottles and caps.
