[0024] In this embodiment, the bottle cap and heat-sealing film are fed separately. The film transferor 520 loads the heat-sealing film into the bottle cap separately, which makes it easier for the heat-sealing film to align with the bottle cap. This ensures that the heat-sealing film and the heat-sealing position inside the bottle cap are aligned, thereby improving the alignment degree between the heat-sealing film and the bottle cap. This improves the consistency of the heat-sealing film application, avoids rework, and effectively reduces the amount of film consumption.

[0025] In one embodiment, please refer to Figure 1 The cell culture bottle cap sealing device 10 further includes a first static eliminator component 800a. The first static eliminator component 800a includes a first static eliminator support 810 and a first static eliminator 820.

The bottle cap transfer longitudinal slide rail 428 is slidably disposed on the first bottle cap transfer transverse slide rail 424, the bottle cap transfer gripper 423 is slidably disposed on the bottle cap transfer longitudinal slide rail 428, and the bottle cap transfer slider 421 is slidably disposed on the second bottle cap transfer transverse slide rail 426. The bottle cap transfer slider 421 is used to carry the bottle caps conveyed by the bottle cap direct vibration feeder 410, and the bottle cap transfer gripper 423 is used to transfer the bottle caps on the bottle cap transfer slider 421 to the bottle cap placement position. In this embodiment, the bottle cap transfer bracket 422 serves as the mounting bracket for the bottle cap transfer gripper 423. The first bottle cap transfer transverse slide rail 424 is mounted on the bottle cap transfer bracket 422. The bottle cap transfer longitudinal slide rail 428 moves along the horizontal direction of the first bottle cap transfer transverse slide rail 424. The bottle cap transfer gripper 423 is slidably connected to the bottle cap transfer longitudinal slide rail 428, allowing the bottle cap transfer gripper 423 to move in two mutually perpendicular directions, facilitating the accurate gripping of the bottle cap onto the bottle cap placement position of the turntable 300.

[0029] The bottle cap transfer slider 421 is slidably connected to the second bottle cap transfer transverse slide rail 426, allowing the bottle cap transfer slider 421 to move along the second bottle cap transfer transverse slide rail 426 in another horizontal direction.

[0030] In one embodiment, please refer to the following: Figure 3 and Figure 4The film cutter 510 includes a film cutting motor 512, a film cutting support 514, a film conveying platform 516, and at least two film cutting columns 518. The film cutting motor 512 is fixedly connected to the film cutting support 514. The film conveying platform 516 is located on the side of the film cutting support 514 away from the film cutting motor 512. The film conveying platform 516 has interconnected film conveying through holes 502 and film cutting through holes 504. The film conveying through holes 502 are used to convey film strips. The film cutting columns 518 are fixedly connected to the lifting end of the film cutting motor 512. The film cutting columns 518 pass through the film cutting through holes 504 to cut the film strips into heat-sealing films. In this embodiment, the film-cutting motor 512 and the film conveying platform 516 are located on both sides of the film-cutting bracket 514, and are arranged opposite to each other. The film conveying platform 516 is hollow inside, and the film conveying through hole 502 serves as the conveying cavity for the film strip. The film-cutting column 518 is fixed on the lifting end of the film-cutting motor 512. Driven by the film-cutting motor 512, the film-cutting column 518 cuts the film strip through the film cutting through hole 504 and pushes out the cut heat-sealing film, making it easy for the film transfer device 520 to remove the heat-sealing film. After the heat-sealing film is removed, the film-cutting motor 512 drives the film-cutting column 518 to descend, so that the film-cutting column 518 comes into contact with the film strip, facilitating the continued conveying of the film strip, thereby cutting the subsequent position of the film strip.

[0031] Further, please refer to Figure 4The film cutter 510 further includes a film cutting buffer column 511 and a film cutting buffer spring 513. The film cutting buffer column 511 is fixedly connected to the lifting end of the film cutting motor 512, and the film cutting buffer spring 513 is sleeved on the film cutting buffer column 511 and abuts against the lifting end of the film cutting motor 512. The film transfer table 516 includes a transfer base 5162 and a film pressing plate 5164. The transfer base 5162 is fixedly connected to the film cutting support 514.

The diaphragm pressing plate 5164 is housed within the diaphragm conveying through hole 502. The diaphragm pressing plate 5164 has a second pressing through hole 508. The film cutting buffer post 511 passes through the first pressing through hole 506 and is movably inserted into the second pressing through hole 508. The film cutting buffer spring 513 passes through the first pressing through hole 506 and abuts against the diaphragm pressing plate 5164. In this embodiment, the transmission base 5162 has the diaphragm conveying through hole 502 and the diaphragm cutting through hole 504, and the first pressing through hole 506 is also located on the transmission base 5162. The film-cutting buffer post 511 is sleeved with the film-cutting buffer spring 513, that is, the film-cutting buffer spring 513 is sleeved on the outside of the film-cutting buffer post 511. Both the film-cutting buffer post 511 and the film-cutting buffer spring 513 pass through the first pressure through hole 506. The end of the film-cutting buffer post 511 is also located in the second pressure through hole 508, which provides space for the film-cutting buffer post 511 to move up and down. The film-cutting buffer spring 513 also contacts the film sheet pressure plate 5164, so that when the film-cutting post 518 cuts the film strip, the film-cutting buffer post 511 and the film-cutting buffer spring 513 push up the film sheet pressure plate 5164, thereby causing the film sheet pressure plate 5164 to hold the film strip against the inner wall of the film conveying through hole 502, so as to avoid the film strip from shifting during cutting and to facilitate the cutting of heat-sealing film that meets the requirements. The membrane cutting buffer spring 513 provides a pressure buffer for the membrane pressing plate 5164, preventing the membrane from being broken by the pressure plates 5164.

[0032] In another embodiment, please refer to Figure 3The film transferor 520 includes a film transfer bracket 522, a film transfer slide rail 524, a film lifting cylinder 526, a film suction adjustment cylinder 528, and at least two film suction tubes 521. The film transfer bracket 522 is disposed adjacent to the film cutting bracket 514. The film transfer slide rail 524 is disposed on the film transfer bracket 522. The film lifting cylinder 526 is slidably disposed on the film transfer slide rail 524. The lifting end of the film lifting cylinder 526 is connected to the film suction adjustment cylinder 528. Each film suction end of the film suction adjustment cylinder 528 is connected to one of the film suction tubes 521 to adjust the spacing between the film suction tubes 521. Each film suction tube 521 is disposed opposite to one of the film cutting columns 518 to pick up the heat-sealing film on the film cutting column 518. In this embodiment, the film transfer bracket 522 serves as a mounting frame for the film transfer slide rail 524, the film lifting cylinder 526, the film suction adjustment cylinder 528, and at least two film suction tubes 521. The film lifting cylinder 526 is slidably connected to the film transfer slide rail 524, allowing the film lifting cylinder 526 to move along the direction of the film transfer slide rail 524. Specifically, the film transfer slide rail 524 is parallel to the radial direction of the turntable 300. The film suction adjustment cylinder 528 is fixedly connected to the lifting end of the film lifting cylinder 526, and the film suction tube 521 is fixed to the film suction end of the film suction adjustment cylinder 528, facilitating the film suction tube 521 to pick up the heat-sealing film cut by the film cutting column 518. The distance between adjacent suction tubes 521 is adjusted by the suction end of the suction cylinder 528. That is, by adjusting the spacing between the suction ends of the suction cylinder 528, the spacing between the suction tubes 521 becomes adjustable. When the spacing between the film cutting columns 518 is adjusted, the spacing of the suction tubes 521 can be adjusted synchronously. Furthermore, by adjusting the spacing between the film cutting columns 518 and the suction tubes 521, the utilization rate of the film strip is improved, and the amount of film strip used is reduced.

The film-pressing swing rod 613 rotates around the rotating shaft of the film-pressing swing motor 615, causing the film-pressing swing rod 613 to swing on the heat-sealing rotating bracket 614. The end of the pressure film swing arm 613 corresponds to the heat sealing transfer claw 616. Specifically, when the heat sealing transfer claw 616 grips the bottle cap, the end of the pressure film swing arm 613 extends into the bottle cap gripped by the heat sealing transfer claw 616, so that the heat sealing film inside the bottle cap is confined therein, avoiding the heat sealing film inside the bottle cap from flying away when the heat sealing rotating bracket 614 rotates, thereby reducing the loss of the heat sealing film.

[0035] In one embodiment, this disclosure also provides a bottle cap sealing machine, including the cell culture bottle cap sealing device described in any of the above embodiments. In this embodiment, the cell culture bottle cap sealing device includes a turntable, a bottle cap feeding assembly, a membrane feeding assembly, a heat sealing assembly, and a feeding assembly; the turntable has multiple bottle cap placement positions, which are sequentially spaced along the edge of the turntable; the bottle cap feeding assembly includes a bottle cap linear vibration feeder and a bottle cap transferor, the bottle cap linear vibration feeder being used for linearly vibrating and conveying bottle caps, and the bottle cap transferor being located between the bottle cap linear vibration feeder and the turntable, the bottle cap transferor being used to linearly vibrate and convey the bottle caps. Bottle caps on the vibratory feeder are transferred to the bottle cap placement position, with the cap opening facing away from the turntable. The film feeding assembly includes a film cutter and a film transferor. The film cutter is used to cut heat-sealing film, and the film transferor is located between the film cutter and the turntable. The film transferor is used to transfer the heat-sealing film from the film cutter to the bottle cap in the bottle cap placement position. The heat-sealing assembly is used to heat-seal the heat-sealing film inside the bottle cap in the bottle cap placement position. The unloading assembly is used to remove the heat-sealed bottle cap. Bottle caps and heat-sealing films are fed separately. The film transferor loads the heat-sealing film separately into the bottle cap, making it easier for the heat-sealing film to align with the bottle cap, thus improving the alignment between the heat-sealing film and the bottle cap, thereby improving the consistency of heat-sealing film application, avoiding rework, and effectively reducing film consumption.
