Description

Technical Field

[0001] This application relates to the field of packaging equipment, and in particular to a filling heat-sealing rotary machine. Background Technology

[0002] In related technologies, due to the special packaging needs of some pharmaceutical or reagent products, the bottom and mouth of the bottle body of such products need to be sealed with aluminum foil. At the same time, to facilitate the grip of the bottle body, raised strips are provided on the outer periphery of the bottle body.

[0003] like Figure 1 Currently, when manufacturing this type of product, it is necessary to first seal the bottom of the bottle with aluminum film using a sealing device to form an aluminum film-sealed bottle 1. Then, the operator moves the aluminum film-sealed bottle 1 to the filling equipment, and the filling equipment fills the product into the aluminum film-sealed bottle 1. The operator then transfers it to the sealing equipment, and the sealing equipment seals the bottle mouth of the filled aluminum film-sealed bottle 1 with aluminum film to complete the sealing process of the aluminum film-sealed bottle 1.

[0004] Regarding the aforementioned technologies, the filling and sealing of aluminum foil-sealed bottles currently require manual assistance, resulting in low overall operational efficiency and a high risk of product leakage during the transfer process. Therefore, there is room for improvement. Summary of the Invention

[0005] To improve the filling and sealing efficiency of aluminum foil-sealed bottles, this application provides a filling and heat-sealing rotary table machine.

[0006] This application provides a filling and heat-sealing rotary table machine, which adopts the following technical solution:

[0007] A filling and heat-sealing rotary table machine includes a conveying mechanism, a filling mechanism, a heat-sealing mechanism, and a transfer mechanism;

[0008] The conveying mechanism includes a frame, on which a turntable is supported. Several placement seats are evenly distributed around the turntable, and the top of each placement seat has a placement slot for placing aluminum foil-sealed bottles. The frame is also provided with a first rotary drive for driving the turntable to rotate.

[0009] The filling mechanism, the hot-press sealing mechanism, and the transfer mechanism are arranged sequentially along the moving path of the placement seat;

[0010] The filling mechanism is used to fill the material into the empty aluminum foil-sealed bottle in the placement slot;

[0011] The hot-press sealing mechanism is used to seal the aluminum film into the mouth end of the filled aluminum film-sealed bottle in the placement groove;

[0012] The transfer mechanism is used to clamp out and transfer the sealed aluminum foil-sealed bottles in the placement slot.

[0013] By adopting the above technical solution, when filling and sealing aluminum foil-sealed bottles, the bottles are placed in the placement slot of a turntable, and the turntable is rotated by the first rotary drive component. The aluminum foil-sealed bottles are then moved sequentially to the filling station, sealing station, and transfer station according to a predetermined path. The filling mechanism, hot-press sealing mechanism, and transfer mechanism then sequentially perform filling, aluminum foil sealing, and transfer operations on the aluminum foil-sealed bottles. During operation, no manual intervention is required to move the aluminum foil-sealed bottles, effectively improving the filling and sealing efficiency of the bottles. At the same time, it helps to reduce the risk of material spillage caused by manual movement.

[0014] Preferably, the hot-press sealing mechanism includes a support base, on which a film cutting assembly, a film winding and unwinding assembly, and an aluminum film roll are disposed;

[0015] The film cutting assembly includes a film cutting mold; the film cutting mold is located above the moving path of the placement seat; the film cutting mold has a limiting groove with openings at both ends; a heating jacket is also supported above the film cutting mold, a film cutting punch is inserted inside the heating jacket, the film cutting mold has a film cutting through hole corresponding to the film cutting punch, the film cutting through hole communicates with the limiting groove, and a lifting drive is also supported above the film cutting mold, the lifting drive is used to drive the film cutting punch through the film cutting through hole into the film cutting mold;

[0016] The film taking and releasing assembly includes a film taking frame and a film releasing frame, which are respectively supported at both ends of the film cutting mold; the film taking frame and the film releasing frame are respectively supported by a film taking shaft and a film releasing shaft; the film taking frame is also provided with a second rotary drive component for driving the film taking shaft to rotate;

[0017] The aluminum film roll is rotatably sleeved on the film-laying shaft, and the aluminum film of the aluminum film roll passes through the limiting groove and is connected to the film-receiving shaft.

[0018] By adopting the above technical solution, when the turntable rotates and drives the placement seat to move the filled aluminum film bottom bottle to the sealing station, the lifting drive pushes the film cutting punch, which has been heated by the heating jacket, downward and makes it pass through the film cutting hole, thereby cutting the aluminum film in the limiting groove and sending the cut aluminum film to the bottle mouth of the aluminum film bottom bottle. The heat carried by the film cutting punch is used to bond the bottom plastic film of the aluminum film to the bottle mouth of the aluminum film bottom bottle, thus completing the sealing process of the aluminum film bottom bottle. After sealing, the lifting drive drives the film cutting punch to move up and reset, and then the second rotary drive drives the film winding to rotate to wind up the waste film.

[0019] Preferably, the hot-press sealing mechanism further includes a limiting component, which includes a limiting plate supported on one side of the film cutting mold, and a limiting cylinder is installed on the limiting plate. The limiting cylinder is oriented towards the sealing station.

[0020] When the cutting punch of the hot-press sealing mechanism moves up and resets from the bottle mouth end of the sealed aluminum film bottom bottle, the limiting cylinder drives the piston rod to press against the outer periphery of the sealed aluminum film bottom bottle.

[0021] By adopting the above technical solution, during the hot-press sealing process, because the cutting punch is heated when cutting the aluminum film, the burrs on the edge of the plastic film at the bottom of the aluminum film may lift up and stick to the cutting punch after the aluminum film is cut. When the cutting punch moves upward, the aluminum film may move along with the aluminum film-sealed bottle due to the adhesion. By setting the limiting cylinder, when the cutting punch is moved up and reset, the limiting cylinder first limits the sealed aluminum film-sealed bottle, which helps to prevent the aluminum film-sealed bottle from being taken out of the placement seat when the cutting punch moves up.

[0022] Preferably, the frame is provided with a lifting adjustment component corresponding to the hot-press sealing mechanism. The lifting adjustment component includes an adjustment support, and the support seat of the hot-press sealing mechanism is vertically slidably connected to the adjustment support. The adjustment support is vertically rotatably connected to an adjustment screw, and the support seat is equipped with a screw nut corresponding to the adjustment screw. The adjustment screw and the screw nut are threadedly connected.

[0023] By adopting the above technical solution, the height of the heat-sealing mechanism can be adjusted. When it is necessary to adapt to aluminum foil-sealed bottles of different specifications, the height of the support can be adjusted by rotating the adjusting screw, thereby precisely adjusting the position of the film-cutting punch relative to the bottle mouth. This ensures that the aluminum foil can accurately cover the bottle mouth during the subsequent sealing process, which helps to improve the applicability of the heat-sealing mechanism.

[0024] Preferably, the adjusting support is vertically connected to the support base with a fixing plate, the fixing plate is disposed opposite to the support base, and a limiting bolt is threaded through the fixing plate, the limiting bolt being abutted against the support base.

[0025] By adopting the above technical solution, there is a certain assembly gap between the lead screw nut and the lead screw. When vibration occurs during equipment operation, it is very easy for the position of the film cutting punch to shift. By tightening the limit bolt against the support seat, the hot-press sealing mechanism is limited and fixed, ensuring that the film cutting punch maintains a precise position during operation. This limits the displacement of the film cutting punch of the hot-press sealing mechanism caused by the assembly gap between the lead screw nut and the adjusting lead screw.

[0026] Preferably, a silicone gasket is placed at the bottom of the placement groove.

[0027] By adopting the above technical solution, the height of aluminum film-sealed bottles in adjacent placement slots may be inconsistent due to manufacturing errors, affecting the sealing effect of subsequent operations. By using silicone gaskets within the placement slots, the elastic properties of silicone effectively compensate for the height differences between the slots, allowing the heat-sealing mechanism to properly seal the aluminum film during the sealing operation.

[0028] Preferably, a support pad is also provided at the bottom of the placement groove, and the support pad abuts against the upper surface of the silicone gasket.

[0029] By adopting the above technical solution, when the aluminum foil-sealed bottle is in direct contact with the silicone gasket, and the bottle moves downward under the pressure of the cutting punch, the portion of the silicone gasket that is not released from the aluminum foil-sealed bottle will cause the aluminum foil at the bottom of the bottle to dent upward, resulting in product defects. By setting up a support base, when the aluminum foil-sealed bottle moves downward under the pressure of the cutting punch, the support base can ensure that the silicone gasket is evenly stressed, thus avoiding the situation where the aluminum foil at the bottom of the bottle dents.

[0030] Preferably, the outer periphery of the aluminum foil-sealed bottle is provided with a raised strip; the inner periphery of the placement groove is provided with a snap-fit ​​groove corresponding to the raised strip on the outer periphery of the aluminum foil-sealed bottle, and the top of the snap-fit ​​groove is open; the snap-fit ​​groove is used for inserting the raised strip.

[0031] By adopting the above technical solution, while placing the aluminum foil-sealed bottle into the placement groove, the protrusions on the outer periphery of the aluminum foil-sealed bottle are embedded in the snap-fit ​​groove on the inner periphery of the placement groove. The engagement between the snap-fit ​​groove and the protrusions limits the aluminum foil-sealed bottle, effectively restricting the bottle from shifting or shaking during the rotation of the turntable, which is beneficial to the subsequent filling and sealing processes.

[0032] Preferably, the bottom of the turntable is provided with an auxiliary support part, which is located below the cutting punch. The auxiliary support part includes a universal ball, and the universal ball abuts against the bottom of the turntable.

[0033] By adopting the above technical solution, the auxiliary support part is used to provide auxiliary support for the area of ​​the turntable located at the sealing station, reducing the deformation and damage that may occur in this area due to long-term impact from the cutting punch; by setting the universal ball, the auxiliary support part is provided for the turntable while effectively reducing the friction between the auxiliary support part and the turntable.

[0034] Preferably, the filling mechanism includes a filling head, a filling pump, and a material tank. The filling head is supported above the moving path of the placement trough, and the inlet and outlet ends of the filling pump are respectively connected to the material tank and the filling pump.

[0035] By adopting the above technical solution, the turntable drives the placement seat to move the aluminum foil-sealed bottle to the filling station. Then, the filling pump extracts the material from the material bucket and injects it into the aluminum foil-sealed bottle through the filling head to realize the filling operation of the aluminum foil-sealed bottle.

[0036] In summary, this application includes at least one of the following beneficial technical effects:

[0037] 1. Through the coordinated action of the conveying mechanism, filling mechanism, hot-press sealing mechanism and transfer mechanism, the aluminum foil bottom-sealed bottle is automatically processed from filling to sealing. The process does not require manual intervention to move the aluminum foil bottom-sealed bottle, which effectively improves the filling and sealing efficiency and reduces the risk of operation error and material leakage caused by manual intervention.

[0038] 2. By setting the limiting component, before the cutting punch of the hot-press sealing mechanism moves up and resets, the limiting cylinder limits the aluminum film bottom bottle located in the placement seat to prevent the aluminum film from sticking to the cutting punch and causing the aluminum film bottom bottle to be lifted up together when the cutting punch moves up.

[0039] 3. By using silicone gaskets and support plates in the placement slots, the silicone gaskets and support plates work together to effectively compensate for the height differences of each placement slot while limiting the force on the silicone gaskets to prevent the aluminum film at the bottom of the aluminum film-sealed bottle from denting.

[0051] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0052] Reference Figure 1 The bottom of the aluminum foil sealed bottle 1 is sealed with aluminum foil, and the outer periphery of the aluminum foil sealed bottle 1 has raised strips 11 on both sides.

[0053] This application discloses a filling and heat-sealing rotary machine, referring to... Figure 2 and Figure 3 It includes a conveying mechanism 2, a filling mechanism 3, a hot-press sealing mechanism 4, and a transfer mechanism 5.

[0054] The conveying mechanism 2 includes a frame 21, a turntable 22, and a first rotary drive component. The bottom of the turntable 22 is rotatably mounted on the frame 21 via bearings. The first rotary drive component is driven by the turntable 22 and is used to drive the turntable 22 to rotate around its own rotation axis. In this embodiment, the first rotary drive component is a geared motor.

[0055] Reference Figure 1 , Figure 3 and Figure 4The turntable 22 has several placement seats 23 evenly distributed around it. Each placement seat 23 has a placement groove 231 formed on it. The placement groove 231 is used for inserting the aluminum film-sealed bottle 1. When the aluminum film-sealed bottle 1 is inserted into the placement groove 231, the top of the aluminum film-sealed bottle 1 extends out of the placement groove 231.

[0056] Reference Figure 1 and Figure 5 The placement groove 231 has several locking grooves 232 corresponding to the outer peripheral protrusions 11 of the aluminum foil-sealed bottle 1. The top of the locking grooves 232 is open to facilitate the insertion of the protrusions 11. When the aluminum foil-sealed bottle 1 is inserted into the placement groove 231, the outer peripheral protrusions 11 of the aluminum foil-sealed bottle 1 are inserted into the corresponding locking grooves 232. The locking grooves 232 limit the aluminum foil-sealed bottle 1 to prevent it from shaking or shifting during movement.

[0057] Reference Figure 2 and Figure 3 The filling mechanism 3 is used to fill the material into the aluminum foil-sealed bottle 1. Specifically, the filling mechanism 3 includes a filling pump 31, a filling head 32, and a material tank 33. The filling pump 31 and the filling head 32 are both fixed to the frame 21 of the conveying mechanism 2 by brackets and are both set close to the turntable 22. The filling head 32 is located above the moving path of the placement seat 23 on the turntable 22. The inlet and outlet ends of the filling pump 31 are connected to the material tank 33 and the filling head 32 respectively through pipelines. Subsequently, when the turntable 22 rotates to move the aluminum foil-sealed bottle 1 in the placement seat 23 to below the filling head 32, the filling pump 31 pumps the material out of the material tank 33 and fills it into the aluminum foil-sealed bottle 1 through the filling head 32 to complete the filling. In this embodiment, the filling pump 31 is a valveless ceramic plunger pump; the material tank 33 is a material tank 33 with a stirrer.

[0058] Reference Figure 2 and Figure 6 The hot-press sealing mechanism 4 is used to bond the aluminum film to the mouth of the aluminum film-sealed bottle 1. Specifically, the hot-press sealing mechanism 4 includes a support base 40, on which a film cutting assembly 41, a film winding and unwinding assembly 42, and an aluminum film roll 43 are provided.

[0059] Reference Figure 6 and Figure 7The film cutting assembly 41 includes a film cutting mold 412; the film cutting mold 412 is connected to one side of the support base 40 through a connecting plate 411, and the film cutting mold 412 is located above the moving path of the placement base 23; the film cutting mold 412 has a limiting groove 4121 with openings at both ends for aluminum film to pass through; a heating jacket 413 is also supported and fixed above the film cutting mold 412, the heating jacket 413 includes a heating ring 4131, a heat-conducting sleeve 4132 is fixedly inserted through the inner circumference of the heating ring 4131, and a film cutting punch 414 is inserted through the inner circumference of the heat-conducting sleeve 4132; the heating ring 4131 is used to cooperate with the heat-conducting sleeve 4132 to heat the film cutting punch 414.

[0060] The film cutting mold 412 has a film cutting through hole 4122 corresponding to the film cutting punch 414. The film cutting through hole 4122 communicates with the limiting groove 4121, and the top of the film cutting through hole 4122 is opposite to and communicates with the heat conducting ring. The film cutting punch 414 can pass through the film cutting through hole 4122 and be inserted into the film cutting mold 412. A lifting drive component 415 is also supported above the film cutting mold 412. The lifting drive component 415 is used to drive the film cutting punch 414 to pass through the film cutting through hole 4122 and be inserted into the film cutting mold 412. In this embodiment, the lifting drive component 415 is a cylinder.

[0061] Reference Figure 6 and Figure 8 The film receiving and dispensing assembly 42 includes a film receiving frame 421 and a film dispensing frame 423, which are respectively connected to both ends of the support base 40 and are respectively located at both ends of the film cutting mold 412. The film receiving frame 421 and the film dispensing frame 423 are respectively horizontally supported by a film receiving shaft 422 and a film dispensing shaft 424. The film receiving frame 421 is also provided with a second rotary drive member 4211 for driving the film receiving shaft 422 to rotate. In this embodiment, the second rotary drive member 4211 is a geared motor.

[0062] Reference Figure 6 and Figure 7 The aluminum film roll 43 is rotatably sleeved on the outer circumference of the film-laying shaft 424, and the aluminum film of the aluminum film roll 43 passes through the limiting groove 4121 and is connected to the film-receiving shaft 422.

[0063] During the sealing process, the turntable 22 rotates to move the placement seat 23 to move the filled aluminum film bottom bottle 1 to below the film cutting hole 4122 at the bottom of the film cutting mold 412. The lifting drive 415 drives the film cutting punch 414, which is heated by the heating jacket 413, to move down and pass through the film cutting hole 4122 to cut the aluminum film in the limiting groove 4121 and move the cut aluminum film to abut against the bottle mouth end of the aluminum film bottom bottle 1. The high temperature of the film cutting punch 414 adheres the bottom plastic film of the aluminum film to the bottle mouth end of the aluminum film bottom bottle 1, thus achieving the sealing process of the aluminum film bottom bottle 1.

[0064] Reference Figure 7 and Figure 8 After sealing, the lifting drive 415 drives the film cutting punch 414 to move up and reset, and then the second rotary drive 4211 drives the film take-up roll to rotate to take up the waste film and pull the complete aluminum film into the limiting groove 4121 of the film cutting mold.

[0065] Reference Figure 6 and Figure 7 A limiting component 44 is provided on the support base 40. The limiting component 44 includes a limiting plate 441 and a limiting cylinder 442. The limiting plate 441 is supported on the side of the film cutting mold 412 facing the turntable 22. The limiting cylinder 442 is vertically installed at the bottom of the limiting plate 441, and the limiting plate 441 is set towards the aluminum film sealed bottle 1 at the sealing station. When the film cutting punch 414 moves upward and resets after the subsequent sealing process, the limiting cylinder 442 first drives its piston rod to abut against the outer periphery of the sealed aluminum film sealed bottle 1, and then the lifting drive component 415 drives the film cutting punch 414 to move upward. This helps to prevent the aluminum film and the aluminum film sealed bottle 1 from being lifted from the placement base 23 together when the film cutting punch 414 moves upward and resets because the burrs on the outer periphery of the aluminum film stick to the film cutting punch 414 when it cuts the aluminum film.

[0066] The frame 21 is provided with an auxiliary support part corresponding to the turntable 22. The auxiliary support part includes a universal ball. The universal ball is located below the film cutting punch 414 of the hot-press sealing mechanism 4, and the ball body is set to abut against the bottom of the turntable 22. The universal ball is used to support and limit the area of ​​the turntable 22 located at the sealing station, reducing the impact of the subsequent downward movement of the film cutting punch 414 on the turntable 22, which could cause the turntable 22 to deform and be damaged.

[0067] Reference Figure 6 and Figure 8 The frame 21 is also equipped with a lifting and adjusting assembly corresponding to the heat-sealing mechanism 4. The lifting and adjusting assembly includes an adjusting support 45 fixed on the frame 21. The adjusting support 45 is vertically connected to the support seat 40 of the heat-sealing mechanism 4 via a guide column. The support seat 40 is slidably connected to the guide column via a guide sleeve, so that the support seat 40 is vertically slidably connected to the adjusting support 45. The adjusting support 45 is also vertically rotatably connected to the support seat 40 via an adjusting screw 451. A screw nut 452 is fixedly inserted through the support seat 40 and the adjusting screw 451. The screw nut 452 and the adjusting screw 451 are threadedly engaged, so that the overall height of the heat-sealing mechanism 4 is adjustable. When the specifications of the aluminum film sealed bottle 1 change, the overall height position of the heat-sealing mechanism 4 can be adjusted by rotating the adjusting screw 451, so that the film cutting punch 414 of the heat-sealing mechanism 4 can better seal the aluminum film at the mouth of the aluminum film sealed bottle 1, which is beneficial to improving the overall applicability of the heat-sealing mechanism 4.

[0068] A fixed plate 453 is vertically connected to the adjusting support 45. The fixed plate 453 is positioned opposite to the support 40 on the side away from the turntable 22. Several limiting bolts 454 are threaded through the fixed plate 453. The limiting bolts 454 abut against the support 40 to limit the position of the support 40. This helps to reduce the deviation in the height position of the film cutting punch 414 of the hot-press sealing mechanism 4 caused by the assembly gap between the lead screw nut 452 and the adjusting lead screw 451 and the vibration during equipment operation.

[0069] Reference Figure 1 and Figure 5 Each placement slot 231 is equipped with a silicone gasket 24. When the aluminum film is sealed to the bottle mouth of the aluminum film bottom bottle 1 by the film cutting punch 414, the silicone gasket 24 can be used to compensate for the depth error inside the placement slot 231 of each placement seat 23. This allows the heat sealing mechanism 4 to tightly fit the aluminum film to the bottle mouth of the aluminum film bottom bottle 1, reducing the possibility of inconsistent heights of the aluminum film bottom bottles 1 in adjacent placement slots 231 due to depth errors in the placement slot 231, which would affect the subsequent heat sealing mechanism 4's ability to tightly seal the aluminum film to the bottle mouth of the aluminum film bottom bottle 1.

[0070] Reference Figure 1 , Figure 4 and Figure 5 A support pad 25 is also placed in the placement groove 231. The support pad 25 is attached to the upper surface of the silicone gasket 24. With the setting of the support pad 25, when the aluminum film is attached to the mouth of the aluminum film sealed bottle 1 by the film cutting punch 414, the support pad 25 can be used to make the silicone gasket 24 evenly stressed. This avoids the situation where the aluminum film at the bottom of the aluminum film sealed bottle 1 is concave upwards due to the area of ​​the silicone gasket 24 not being stressed when the aluminum film sealed bottle 1 directly contacts the silicone gasket 24, which would cause the aluminum film at the bottom of the aluminum film sealed bottle 1 to be unqualified.

[0071] The support pad 25 has a through hole 250. The through hole 250 is provided so that when the support pad 25 is moved into the placement groove 231, the air in the placement groove 231 can be discharged through the through hole 250, so that the support pad 25 can be moved into the placement groove 231 smoothly.

[0072] The support pad 25 has protrusions 251 on its outer periphery, and an annular groove 233 is formed on the inner periphery of the placement groove 231 corresponding to the protrusions 251. The annular groove 233 communicates with the snap-fit ​​groove 232 on the inner periphery of the placement groove 231. The protrusions 251 are embedded in the annular groove 233 to support and limit the position of the support pad 25. When installing the support pad 25, first insert the protrusions 251 on the outer periphery of the support pad 25 into the snap-fit ​​groove 232. After the support pad 25 moves downward until the protrusions 251 are located in the snap-fit ​​groove 232, rotate the support pad 25 to displace the protrusions 251 from the snap-fit ​​groove 232, so that the support pad 25 can be securely installed in the placement groove 231.

[0073] Reference Figure 2 and Figure 9 The frame 21 is supported by a transfer groove 6 corresponding to the turntable 22. The transfer groove 6 is located close to the turntable 22 and extends downward at an angle away from the turntable 22. The transfer mechanism 5 is used to clamp the sealed aluminum film-sealed bottle 1 from the placement seat 23 and transfer it into the transfer groove 6. The transfer mechanism 5 includes a transfer drive 52 and a pneumatic gripper cylinder 53. The pneumatic gripper cylinder 53 is located above the moving path of the placement seat 23 on the turntable 22. The transfer drive 52 is used to drive the pneumatic gripper cylinder 53 to move back and forth between the transfer station and the transfer groove 6. The transfer drive 52 includes a horizontal drive cylinder 521 and a vertical drive cylinder 522. The horizontal drive cylinder 521 is horizontally supported above the turntable 22 by the transfer bracket 51. The vertical drive cylinder 522 is vertically connected downward to the piston rod of the horizontal drive cylinder 521. The pneumatic gripper cylinder 53 is vertically connected downward to the end of the piston rod of the vertical drive cylinder 522.

[0074] When the turntable 22 rotates to drive the placement seat 23 to move the sealed aluminum foil-bottomed bottle 1 to the transfer station, the horizontal drive cylinder 521, the vertical drive cylinder 522, and the pneumatic gripper cylinder 53 work together to clamp the aluminum foil-bottomed bottle 1 out of the placement seat 23 and place it into the transfer groove 6 to complete the transfer operation of the aluminum foil-bottomed bottle 1.

[0075] The implementation principle of this application embodiment is as follows: when filling and sealing the aluminum foil-sealed bottom bottle 1, the following steps are included:

[0076] Filling process: When the turntable 22 rotates to drive the placement seat 23 to move the empty aluminum foil sealed bottle 1 to the filling station, the filling pump 31 pumps the material in the material tank 33 out and fills it into the aluminum foil sealed bottle 1 through the filling head 32 to complete the filling operation.

[0077] Sealing process: When the turntable 22 rotates to drive the placement seat 23 to move the filled aluminum film sealed bottle 1 to the sealing station, the lifting drive 415 drives the film cutting punch 414 to move down to cooperate with the film cutting mold 412 to punch the aluminum film into shape, and move the punched aluminum film to the bottle mouth end of the aluminum film sealed bottle 1. The aluminum film is then bonded to the bottle mouth end of the aluminum film sealed bottle 1 by the high temperature of the film cutting punch 414 to complete the sealing operation.

[0078] Transfer process: When the turntable 22 rotates to drive the placement seat 23 to move the sealed aluminum film bottom bottle 1 to the transfer station, the horizontal drive cylinder 521, the vertical drive cylinder 522 and the pneumatic gripper cylinder 53 work together to clamp the aluminum film bottom bottle 1 out of the placement seat 23 and put it into the transfer groove 6, thus completing the transfer operation of the aluminum film bottom bottle 1.

[0079] The entire filling and sealing process requires no manual intervention to move the aluminum foil-sealed bottle 1, effectively improving overall processing efficiency.

[0080] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
