[0079] This embodiment also provides a double-station automatic sealing method for a humidification bottle, using the aforementioned double-station automatic sealing device for a humidification bottle, the sealing method comprises the following steps:

[0080] S1, material distribution and positioning, the humidification bottle moves continuously or discontinuously along the conveyor line 101 to the bottle body distribution and positioning device 1, and after the bottle body incoming material detection device 107 detects the arrival of the bottle body (and the second bottle detection device 105 does not detect the bottle body at this time), the motor drive mechanism 108 drives the turntable distribution mechanism 109 to rotate a certain angle to allow the first bottle body to pass, and the first bottle body moves along the conveyor line 101 to the spacing positioning plate 103. At this time, the second bottle positioning telescopic rod 102 extends until the turntable distribution mechanism 109 allows the second bottle body to pass and moves to the second bottle positioning telescopic rod 102, so that the first bottle body and the second bottle body are placed at a fixed distance. At this time, even if the bottle body incoming material detection device 107 detects the arrival of the bottle body, the turntable distribution mechanism 109 will no longer allow the bottle body to pass, so as to avoid collision and extrusion of the bottle body at this station. If the third bottle detection device 106 detects the bottle body, it means that the equipment is faulty and one more bottle body has entered. At this time, an alarm is given for abnormal distribution of materials;

[0081] S2, bottle loading, after two bottles are placed along a fixed interval, the X-axis motor driving structure 205 drives the X-axis module 206 to move above the bottles, and the Z-axis motor driving structure 204 drives the Z-axis module 203 to move downward until the first bottle grabbing part 208 and the second bottle grabbing part 209 are in contact with the two bottles respectively, and the grabbing fixed structure 207 controls the first bottle grabbing part 208 and the second bottle grabbing part 209 to clamp the two bottles, and then the Z-axis module 203 moves upward, the X-axis module 206 moves to above the bottle one-way conveying device 7, and the Z-axis module 203 moves downward to place the two bottles on the bottle one-way conveying device 7, and the grabbing fixed structure 207 controls the first bottle grabbing part 208 and the second bottle grabbing part 209 to release, and the Z-axis module 203 moves upward to prepare for the next loading operation;

[0082] S3, the bottle body is conveyed once, the left front and back moving telescopic rod 705 and the right front and back moving telescopic rod 708 drive the left positioning plate 714 and the right positioning plate 711 to move forward synchronously, the blocking strip 712 extends and clamps the side walls of the two bottle bodies, and then the left and right moving motors 710 control the module conveying plate 707 to move one station to the left, the blocking strip 712 and the positioning rod 713 drive the two bottle bodies to move accordingly, and then the left and right moving telescopic rods 705 and the right front and back moving telescopic rods 708 drive the left positioning plate 714 and the right positioning plate 711 to move backward synchronously, the blocking strip 712 retracts, and the left and right moving motors 710 control the module conveying plate 707 to move one station to the right, ready for the next conveying;

[0083] S4, side branch alignment, after the two bottles are transported to the right place, the two positioning cards 304 extend to position the two bottles, the alignment telescopic rod 310 moves down to make the two elastic alignment structures 305 contact the bottles respectively, and the two alignment motors 309 control the two elastic alignment structures 305 to rotate respectively to achieve alignment, and then the alignment telescopic rod 310 moves up to make the two elastic alignment structures 305 separate from the bottles, ready for the next alignment;

[0084] S5, the bottle is transported for the second time, the telescopic rod moves forward and backward to control the positioning plate to move forward, the baffle strip 712 extends and clamps the side walls of the two bottles, and the positioning rod 713 moves down to clamp the side branches of the two bottles to prevent the side branches from shaking during the movement of the bottles, which will affect the side mouth sealing in the next step. Then the left and right moving motor 710 controls the module conveying plate 707 to move one station to the left, and the baffle strip 712 and the positioning rod 713 drive the two bottles to move accordingly. Then the telescopic rod moves forward and backward to control the positioning plate to move backward, the baffle strip 712 retracts, and the positioning rod 713 moves up. The left and right moving motor 710 controls the module conveying plate 707 to move one station to the right to prepare for the next transport;

[0085] The difference between this step and S3 is that in this step, the side branch of the bottle body needs to be pressed by the positioning rod 713 to prevent it from shaking, while in the bottle conveying of S3 and S8, the side branch of the bottle body does not need to be pressed, which can reduce unnecessary actions of the equipment, save resources and improve the reliability of the equipment. Therefore, in the bottle one-way conveying device 7 of this device, the positioning rod 713 and the up and down moving telescopic rod 704 that controls its up and down movement can be set at two places, and they can be set at the station of the secondary conveying of the bottle body. The positioning rod 713 can be set or not set at the station of the primary conveying of the bottle body and the tertiary conveying of the bottle body.

[0086] S6, sealing the first bottle. In S5, the first bottle is conveyed to the top of the bottle support block 413, and the lifting telescopic rod 412 moves upward to move the first bottle to the sealing station. The left clamping telescopic rod 414 drives the left clamping mechanism 415, and the right clamping telescopic rod 421 drives the right clamping mechanism 418 to move toward each other to clamp the first bottle. The top sealing telescopic rod 420 drives the top opening heating mechanism 416 and the top opening stripping mechanism 417 to move downward to press the top opening material belt onto the top opening. Under the action of the top opening heating mechanism 416, the sealing film is hot-melted onto the top opening of the bottle. Then, the top stripping telescopic rod 419 drives the top opening stripping mechanism 417 to move upward to separate the sealing film from the top opening material belt. The top sealing telescopic rod 420 drives the top opening heating mechanism 416 and the top opening stripping mechanism 417 to move upward away from the top opening of the bottle, and the top opening sealing is completed.

[0087] The side sealing telescopic rod 437 drives the side opening heating mechanism 438 and the side opening stripping mechanism 436 to move rightward, pressing the side opening material belt onto the side opening, and the sealing film is hot-melted onto the side opening of the bottle body under the action of the side opening heating mechanism 438, and then the side stripping telescopic rod 435 drives the side opening stripping mechanism 436 to move leftward so that the sealing film is separated from the side opening material belt, and the side sealing telescopic rod 437 drives the side opening heating mechanism 438 and the side opening stripping mechanism 436 to move leftward away from the side opening of the bottle body, and the side opening sealing is completed;

[0088] The lifting telescopic rod 412 moves downward to move the first bottle to the conveying position, ready for the next conveying;

[0089] S7, sealing the second bottle body. The second bottle body sealing device 5 has the same structure as the first bottle body sealing device 4, and the sealing process of the second bottle body is also the same as the sealing process of the first bottle body in S6;

[0090] S8, the bottle body is transported three times, and the two bottles are moved forward one station again. The transport process is consistent with S3;

[0091] S9, bottle unloading, the bottle unloading device 6 has the same structure as the bottle loading device 2, and the bottle unloading process is the same as the bottle loading process in S2, and the bottle is moved from the bottle one-way conveying device 7 to the conveyor belt of the next process;
