A conveying path sealing and isolating system

Abstract

The present invention discloses a conveyor path sealing and isolation system that eliminates the need for horizontal space required for the receiving components to operate, i.e., translate. To prevent interference between the receiving components and the sealing and isolation components during isolation between two chambers, the system utilizes at least the structural feature of adjacent receiving turntables being arranged vertically in alternating areas of the conveyor path, guiding the two receiving turntables to expand their vertical spacing and freeing up space for the sealing and isolation components to enter a sealing operation state. The conveyor path sealing and isolation system effectively reduces the horizontal size of the space required for the receiving components to operate, allowing the system to be used with a smaller footprint, avoiding occupying the space required for the layout of other components and facilitating their design.

Description

Technical Field

[0001] The present invention relates to the technical field of container conveying, and in particular to a technology for isolating adjacent working spaces along a conveying path. Background Art

[0002] The integrated blowing, filling and capping technology features two chambers, one housing a rotating bottle blowing unit and the other housing a filling unit. The two chambers are connected or isolated only by a sealing isolation unit mounted on the frame. This isolation unit features a through-hole, allowing direct connection between the two chambers. The sealing door comprises a movable door panel, which is pushed and pulled horizontally by a linear drive unit employing a pneumatic or electric cylinder. The movable door panel's horizontal linear motion allows it to cover the through-hole horizontally. The sealing structure includes inflatable sealing rings around the through-hole. Once the movable door panel is aligned with the through-hole, the spacing between them remains constant. Compressed gas is introduced into the inflatable sealing ring, causing it to expand and establish a sealed connection between the movable door panel and the sealing ring. Consequently, the two cavities on either side of the sealing isolation component cannot be connected through the through-hole, and are isolated at the through-hole.

[0003] In the prior art, the sealing operation requires horizontal translation of a receiving component within the chamber housing the rotating bottle blowing unit to a position away from the through-hole, preventing interference between the receiving component and the sealing isolation component while isolating the two chambers. The receiving component is equipped with a receiving turntable, which uses bottle clamps on the turntable or, in conjunction with a protective plate, a mechanism at its edge to grip and transport bottles. Horizontal translation of the receiving component can occur in either a linear or arcuate manner. The former requires at least linear horizontal movement of the receiving turntable, while the latter requires swinging motion of the receiving turntable around a pivot point. This requires a relatively large horizontal space for the receiving component's translational movement. The horizontal space requirement is essentially the floor space of the entire machine, which has a limited upper limit and limited layout requirements. A larger horizontal space required for the receiving component to operate inevitably reduces the spatial layout of other components, complicating their design. Summary of the Invention

[0004] The technical problem to be solved by the present invention is how to reduce the horizontal size of the space required for the receiving components to participate in the work, thereby obtaining a conveying path sealing isolation system with small horizontal size.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following design concept, namely, the inventive concept: first, horizontal translational movement of the receiving component is avoided, thereby eliminating the space required for the receiving component to participate in the work, namely, translational movement, in the horizontal direction; then, to avoid interference between the receiving component and the sealing isolation component during the period of isolating the two chambers, at least the structural feature of the adjacent receiving turntables being distributed up and down in the alternating areas of the conveying path is utilized to guide the two receiving turntables to expand the vertical spacing, freeing up space for the sealing isolation component to enter the sealing operation state. Because the vertical space of the factory interior is more abundant than the horizontal space, there is sufficient space in the vertical direction to meet the space requirements for expanding the spacing between the two receiving turntables.

[0006] Based on this inventive concept, the present invention provides two technical solutions. One is based on a non-inflatable sealing ring. After the turntable spacing is expanded, the limiting mechanism not only controls the relative position between the movable door panel and the sealing ring, but also controls the degree of compression between the movable door panel and the sealing ring, thereby ensuring the final sealing connection between the movable door panel and the sealing ring. The other is based on an inflatable sealing ring. After the turntable spacing is expanded, the inflatable sealing ring is inflated by gas to establish the final sealing connection.

[0067] The first embodiment of the present invention is as follows Figure 1 、 2 , 3, 4, 5, 6, 7, and 8.

[0068] The conveying path sealing and isolation system includes a receiving component, a guide component, a sealing and isolation component 1, and a lifting component 14. After commissioning, the conveying path sealing and isolation system is integrated into the frame of an integrated machine, such as a blower-filler-capper. The internal compartments of the integrated machine are divided into chambers, and the sealing and isolation component 1 is integrated into the partition structure used to separate the chambers. The conveying path sealing and isolation system includes a chamber on either side of the sealing and isolation component 1, meaning a sealing and isolation component 1 is positioned between the two chambers. The sealing and isolation components 1 connect and isolate the chambers. Receiving components are distributed within the chambers, each with a conveying path. Each receiving component includes a receiving turntable, with the conveying path located at the edge of the receiving turntable. The conveying paths of the receiving turntables are connected and interconnected to form the overall conveying path of the conveying path sealing and isolation system. The overall conveying path passes through the sealing and isolation component 1, with the guide component located at the junction of the conveying paths. The sealing and isolation component 1 includes a fixed door, a movable door, and a drive member 2. The fixed door includes a fixed door panel 3 and a sealing ring 11. The fixed door panel 3 is mounted on the partition of the integrated machine and is sealed to each other. The fixed door panel 3 is provided with a through-hole, and a sealing ring 11 is mounted on the fixed door panel 3 and distributed around the through-hole. The driver 2 drives the movable door to move linearly in a direction parallel to the fixed door panel 3. The driver 2 provides the linear force and can be a linear cylinder, a hydraulic cylinder, an electric cylinder, or a crank-connecting rod-based power assembly. The movable portion of the driver 2, such as the piston rod and rocker arm, is connected to the movable door, while the fixed portion of the driver 2, such as the cylinder body and motor, can be mounted on the frame or the fixed door. Overall, it is sufficient to generate relative motion between the movable door and the fixed door panel 3.

[0069] Among the adjacent receiving turntables located on both sides of the fixed door panel 3, part of the edge of one receiving turntable passes through the through hole and protrudes on one side of the fixed door panel 3, and the other receiving turntable is located entirely on one side of the fixed door panel 3. The receiving turntable whose part of the edge passes through the through hole and protrudes on one side of the fixed door panel 3 is recorded as receiving turntable I 12, and the receiving turntable located entirely on one side of the fixed door panel 3 is recorded as receiving turntable II 13. Part of the edge of receiving turntable I 12 and part of the edge of receiving turntable II 13 are distributed vertically in an upper and lower relationship. Overall, this is due to the structural design that receiving turntable I 12 is higher than receiving turntable II 13. Receiving turntable I 12 is directly installed on the frame through the transmission structure and connected to the transmission structure of the entire machine, while receiving turntable II 13 is installed on the frame through the lifting component 14. The lifting component 14 drives the receiving turntable II 13 to move linearly in the vertical direction, thereby adjusting the vertical distance between the receiving turntables located on both sides of the fixed door panel 3 and adjacent to each other, namely, the receiving turntable I 12 and the receiving turntable II 13. In the initial state, the lifting component 14 places the receiving turntable II 13 at the highest point, and the distance between the receiving turntable I 12 and the receiving turntable II 13 is the smallest.

[0070] The lifting component 14 includes a transmission assembly and a telescopic assembly. The transmission assembly includes a drive shaft 15 and a sleeve. The sleeve is mounted on the frame, with the drive shaft 15 located within the sleeve and connected to the sleeve via a bearing. After installation, the centerline of the drive shaft 15 is vertical. The drive shaft 15 is connected to the transmission structure of the entire machine. The telescopic assembly includes a loading plate 16, a mounting sleeve 17, a support base 18, and an electric push rod 19. The electric push rod 19 is mounted on the frame, and the loading plate 16 is mounted on the electric push rod 19.

[0071] The electric push rod 19 includes a telescopic unit 20 and a motor. The telescopic unit 20 comprises a support sleeve 21, a screw 22, and a screw sleeve 23. A sliding sleeve is mounted on the outside of the screw sleeve 23. The screw sleeve 23 is movably mounted within the sleeve, allowing the sleeve 23 to slide along the centerline of the support sleeve 21. The screw 22 and the sleeve 23 are threaded together. When the screw 22 rotates, the support sleeve 21 moves linearly relative to the support sleeve 21, achieving the telescopic effect of the entire telescopic unit 20 at the screw sleeve 23. A gear is mounted on the outside of the screw 22.

[0072] The telescopic assembly has three telescopic units 20, all of which are not aligned in a straight line, forming a triangular arrangement. During installation, the support sleeve 21 is fixedly connected to the frame, and the three telescopic units 20 are connected by a chain. The motor is mounted on the frame and connected to the screw 22 of only one of the telescopic units 20, thereby enabling synchronous drive of the three telescopic units 20. The screws 22 are all fixedly connected to the carrier plate 16, so that when the electric push rod 19 is activated, it can raise or lower the height of the carrier plate 16, thereby driving the carrier plate 16 in the vertical direction. The mounting sleeve 17 is fixedly mounted on the carrier plate 16, and the receiving turntable II 13 is fixedly mounted on the top of the support base 18. The bottom of the support base 18 is cylindrical and mounted within the mounting sleeve 17 via a bearing, allowing the receiving turntable II 13 to rotate on the carrier plate 16. The interior of the support base 18 is a hollow channel structure for accommodating the drive shaft 15. The centerline of the channel inside the support base 18 coincides with the centerline of the cylindrical bottom portion of the support base 18. The transmission shaft 15 is connected to the support base 18 via a flat key, and the support base 18 and the transmission shaft 15 are in sliding connection. Specifically, the support base 18 is internally provided with a keyway, located at the edge of the channel, and the two are connected. A flat key is provided on the transmission shaft 15, and the end of the transmission shaft 15 with the flat key extends into the channel of the support base 18, and the flat key is embedded in the keyway. When the transmission shaft 15 rotates, the support base 18 rotates accordingly, and the receiving turntable II 13 rotates; when the receiving turntable II 13 is raised or lowered, that is, when the support base 18 is raised or lowered, the flat key can slide in the keyway, and the transmission shaft 15 can slide in the channel of the support base 18, thereby allowing the receiving turntable II 13 to move linearly in the vertical direction relative to the transmission shaft 15.

[0073] The movable door includes a movable door panel 5, a door frame 6, and a closing member 7. The movable door panel 5 is movably mounted on the door frame 6, which is mounted on the fixed door panel 3 via a linear guide rail, and the movable door panel 5 is in an upright state. A support column is provided on the movable door panel 5, and a sliding sleeve is provided on the door frame 6. The support column is inserted into the sliding sleeve, and the support column and the sliding sleeve are slidably connected. A flange structure is provided at one end of the support column, and a return spring I8 is installed on the outside of the sliding sleeve. The return spring I8 is located between the flange and the door frame 6. In the initial state, the return spring I8 is in a compressed state, thereby driving the movable door panel 5 to be tightly pressed against the door frame 6. In the initial state, the driving member 2 is retracted, and the door frame 6 is located at one end of the fixed door panel 3. When the driving member 2 is extended, the door frame 6 moves toward the other end of the fixed door panel 3 until the movable door panel 5 is located at the through hole of the fixed door panel 3.

[0074] The driving member 2 pushes and pulls the door frame 6 and the movable door panel 5 to move together. The linear movement direction of the movable door panel 5 relative to the fixed door panel 3 based on the driving member 2 is perpendicular to the linear movement direction of the movable door panel 5 relative to the door frame 6. In this way, the linear movement direction of the movable door panel 5 relative to the door frame 6 is perpendicular to the fixed door panel 3.

[0075] The movable door panel 5 is provided with a first escape groove 9 to accommodate the portion of the edge of the receiving turntable I 12 that protrudes from the fixed door panel 3. The movable door panel 5 is provided with a second escape groove 10 to accommodate the portion of the edge of the receiving turntable II 13. The first escape groove 9 and the second escape groove 10 are both oriented horizontally and in opposite directions. The first escape groove 9 and the second escape groove 10 are not directly connected. In addition, in order to accommodate the different heights of the receiving turntable I 12 and the receiving turntable II 13, the first escape groove 9 and the second escape groove 10 are also at different vertical heights. In the initial state, the movable door panel 5 is away from the through hole of the fixed door panel 3, and the partial edge portion of the receiving turntable I 12 protruding on the side of the fixed door panel 3 is located in the extension direction of the first avoidance groove 9; when the receiving turntable II 13 descends along with the lifting component 14, the vertical distance between the partial edge portion of the receiving turntable II 13 and the partial edge portion of the receiving turntable I 12 protruding on the side of the fixed door panel 3 reaches the maximum, and the partial edge portion of the receiving turntable II 13 is located in the extension direction of the second avoidance groove 10.

[0076] To allow the edge of the receiving turntable I 12 protruding from the side of the fixed door panel 3 to be embedded in the first avoidance groove 9 after the driving member 2 drives the movable door panel 5 to move, the first avoidance groove 9 has an open structure at one end. In order to ensure a tight connection between the fixed door panel 3 and the movable door panel 5, the fixed door panel 3 is provided with a protrusion 4 for embedding in the first avoidance groove 9, and a sealing ring 11 is distributed on the surface of the protrusion 4. When the receiving turntable II 13 descends and the driving member 2 pushes the movable door panel 5 toward the other end of the fixed door panel 3, the edge of the receiving turntable II 13 can be embedded in the second avoidance groove 10, and the edge of the receiving turntable I 12 protruding from the side of the fixed door panel 3 can be embedded in the first avoidance groove 9. The sealing ring 11 is located between the fixed door panel 3 and the movable door panel 5, and the protrusion 4 on the fixed door panel 3 is embedded in the first avoidance groove 9.

[0077] In this embodiment, the fixed door panel 3 is sealed to the movable door panel 5 via a sealing ring 11, which requires the participation of the closing member 7. The closing member 7 is a cylinder mounted on the fixed plate via a mounting bracket, and the cylinder body is fixedly connected to the fixed door panel 3. The closing member 7 is located on the other side of the fixed door panel 3, that is, the side with the through hole. In the initial state, the closing member 7 is retracted. When the movable door panel 5 is located at the through hole of the fixed door panel 3, the telescopic rod of the closing member 7 extends, pushing the movable door panel 5, causing it to move toward the position of the fixed door panel 3. The movable door panel 5 is tightly pressed against the fixed door panel 3, and the fixed door and movable door panels 5 are sealed by the sealing ring 11. The chambers on both sides of the fixed door panel 3 cannot communicate through the through hole.

[0078] Bottle clamps are installed on the edge of the receiving turntable I 12, and a latch is installed on the edge of the receiving turntable II 13. In this embodiment, the guide components include an outer guard plate I 24 and an inner guard plate I 25. Both outer guard plate I 24 and inner guard plate I 25 are mounted on a swing mechanism equipped with a cylinder. Both outer guard plate I 24 and inner guard plate I 25 are mounted on the frame in a swinging manner, with the swing direction in the horizontal plane. The cylinder bodies are mounted on the frame, and the cylinder piston rods are connected to either outer guard plate I 24 or inner guard plate I 25. The swing mechanism has two cylinders, one for outer guard plate I 24 and the other for inner guard plate I 25. Initially, outer guard plate I24 is positioned outside receiving turntable II13, with one end extending through the through-hole of fixed door panel 3 and into the interior of receiving turntable I12. Inner guard plate I25 is positioned inside receiving turntable II13. After the swing mechanism drives outer guard plate I24 and inner guard plate I25 to move, outer guard plate I24 completely detaches from receiving turntable I12 and positions itself outside receiving turntable I12, extending into the interior of receiving turntable II13. Inner guard plate I25 moves closer to the center of receiving turntable II13. Initially, the overall conveying path lies between the receiving turntable and guard plates, and within the range of motion of the bottle clamps.

[0079] When used for conveying purposes, the chambers on both sides of the fixed door panel 3 are connected through a through-hole. Bottles are fed from the receiving turntable II 13, with the bottle necks embedded in the latches and one side of the bottleneck restricted by the outer guard plate I 24. The receiving turntables I 12 and II 13 both rotate in opposite directions. When the bottle is pushed to the through-hole of the fixed door panel 3, the bottle neck is guided by the inner guard plate I 25 and pushed out of the latches of the receiving turntable II 13. Simultaneously, the bottle neck is smoothly clamped by the bottle clamp of the receiving turntable I 12. Depending on actual needs, the bottle can also be conveyed from the receiving turntable I 12 to the receiving turntable II 13. However, when the bottle is transferred, it is guided by the end of the outer guard plate I 24, pushed out of the bottle clamp of the receiving turntable I 12, and simultaneously embedded in the latches of the receiving turntable II 13.

[0080] When used for the purpose of isolating a chamber, the fixed door panel 3 is sealed to the movable door panel 5 , and the chambers on both sides of the fixed door panel 3 cannot communicate through the through hole. First, drive the receiving turntable Ⅱ13 to descend; then, drive the outer guard plate Ⅰ24 and the inner guard plate Ⅰ25 to move toward the receiving turntable Ⅱ13, ensuring that the end of the outer guard plate Ⅰ24 is out of the through hole of the fixed door panel 3 and the inner guard plate Ⅰ25 is located on the inner side of the receiving turntable Ⅱ13; then, the movable door panel 5 moves to the front of the through hole of the fixed door panel 3, that is, between the receiving turntable Ⅰ12 and the receiving turntable Ⅱ13, and part of the edge of the receiving turntable Ⅰ12 is embedded in the first avoidance groove 9, and part of the edge of the receiving turntable Ⅱ13 is embedded in the second avoidance groove 10. The protrusion 4 on the fixed door panel 3 is embedded in the first avoidance groove 9, and the closing part 7 presses the movable door panel 5 toward the position of the fixed door panel 3, prompting the movable door panel 5 to be tightly pressed on the sealing ring 11. Finally, the fixed door panel 3 is sealed and connected to the movable door panel 5, and the through hole of the fixed door panel 3 is closed by the movable door panel 5.

[0081] The second embodiment is different from the first embodiment in that the outer guard plate I and the inner guard plate I are directly fixed on the frame, and the operation of isolating the two chambers is carried out by disassembling and assembling the outer guard plate I and the inner guard plate I.

[0082] The third embodiment, such as Figure 9 As shown, the difference between this embodiment and the first embodiment is that the edge of the receiving turntable I 12 and the edge of the receiving turntable II 13 are both provided with a snap-in. The guide component includes two guard plates 26, one guard plate corresponding to the receiving turntable I 12 and the other guard plate corresponding to the receiving turntable II 13. Both guard plates 26 are fixedly mounted on the frame. One of the guard plates 26 is located on the outside of the receiving turntable I 12 and one end of the guard plate 26 extends into the inside of the adjacent receiving turntable II 13. The other guard plate 26 is located on the outside of the receiving turntable II 13 and one end of the guard plate 26 extends into the inside of the adjacent receiving turntable I 12. Both guard plates 26 pass through the through-hole of the fixed door panel. The overall conveying path is located between the receiving turntable and the guard plate 26. The operation of isolating the two chambers is carried out by disassembling and assembling the outer guard 26.

[0083] The fourth embodiment, as Figure 10As shown, this embodiment differs from the third embodiment in that one guard plate 26 is an integral structure, while the other guard plate is a split structure. Specifically, the split guard plate includes a limit plate I 27 and a guide plate I 28. The split guard plate corresponds to the receiving turntable I 12. The limit plate I 27 of the split guard plate is located on the outside of the receiving turntable I 12, while one end of the guide plate I 28 is located on the inside of the receiving turntable II 13. The other end of the guide plate I 28 passes through the through-hole of the fixed door panel and is continuously distributed with the limit plate I 27. The guide plate I 28 is mounted on the swing mechanism; the guard plate 26 on the outside of the receiving turntable II 13 is also mounted on the swing mechanism. The limit plate I 27 is located entirely on the other side of the fixed door panel and does not pass through the through-hole of the fixed door panel. The guide plate I 28 participates in the operation of isolating the two chambers by swinging toward the inside of the receiving turntable II 13, disengaging it from the through-hole of the fixed door panel. The guard plate 26 also participates in the operation of isolating the two chambers by swinging toward the inner side of the receiving turntable II 13.

[0084] The fifth embodiment, as Figure 11 As shown, this embodiment differs from the first embodiment in that bottle clamps are installed on the edges of both receiving turntable I 12 and receiving turntable II 13. The guide assembly includes two guard plates 26, both located on the inner sides of the receiving turntables: one guard plate 26 is located on the inner side of receiving turntable I 12, and the other guard plate 26 is located on the inner side of receiving turntable II 13. Both guard plates 26 are fixedly mounted to the frame. The entire conveying path is within the range of motion of the bottle clamps. The removal and installation of the guard plates 26 facilitates the isolation of the two chambers.

[0085] The sixth embodiment is different from the fifth embodiment in that the guard plate is mounted on the swing mechanism. The guard plate is swung and positioned further inward to participate in the operation of isolating the two chambers.

[0086] The seventh embodiment differs from the first embodiment in that a latch is provided at the edge of the receiving turntable I, and a bottle clamp is provided at the edge of the receiving turntable II. Compared with the first embodiment, the distribution positions of the latch and the bottle clamp are swapped. The guide component includes an outer guard plate II and an inner guard plate II, and the outer guard plate II and the inner guard plate II are directly fixed to the frame. The outer guard plate II is located on the outside of the receiving turntable I, and one end of the outer guard plate II extends into the inside of the receiving turntable II. The inner guard plate II is located on the inside of the receiving turntable I. The overall conveying path is distributed between the receiving turntable and the guard plate and within the range of motion of the bottle clamp. The operation of isolating the two chambers is carried out by disassembling and assembling the outer guard plate II and the inner guard plate II.

[0087] An eighth embodiment differs from the seventh embodiment in that outer guard plate II includes a limit plate II and a guide plate II. Limit plate II is located outside the receiving turntable, while one end of guide plate II is located inside the receiving turntable II. The other end of guide plate II passes through the through-hole of the fixed door panel and is continuous with limit plate II. Guide plate II and inner guard plate II are both mounted on a swing mechanism. By rotating guide plate II and inner guard plate II, the inner guard plate II is positioned further inward and guide plate II is disengaged from the through-hole of the fixed door panel, thereby isolating the two chambers.

[0088] The ninth embodiment is different from the first embodiment in the lifting component. In this embodiment, the lifting component includes a transmission component and a telescopic component. The transmission component is installed on the telescopic component, and it is driven by the telescopic component to rise and fall together with the receiving turntable II. The transmission component is provided with a transmission shaft and a sleeve; the telescopic component includes a carrier plate, a mounting sleeve, a support seat, and an electric push rod. The carrier plate is installed on the electric push rod, and the electric push rod drives the carrier plate to move in the vertical direction. The mounting sleeve is fixedly installed on the carrier plate; the receiving turntable II is fixedly installed on the top of the support seat, the bottom of the support seat is cylindrical and the bottom of the support seat is installed in the mounting sleeve through a bearing, the transmission shaft is fixedly connected to the support seat, the sleeve is fixedly connected to the carrier plate, the transmission shaft is located in the sleeve, and the transmission shaft and the sleeve are movably connected through a bearing.

[0089] A tenth embodiment: This embodiment differs from the first embodiment in that there is no return spring I between the movable door panel and the door frame. In the initial state, the relative positions of the movable door panel and the door frame are random.

[0090] An eleventh embodiment, as Figure 12 As shown, the difference between this embodiment and the first embodiment is that the closing member includes a guide plate 29 and a guide post 30. The guide plate 29 is fixedly connected to the fixed door panel 3. The guide plate 29 is provided with a guide groove 31. The guide groove 31 extends in a direction parallel to the fixed door panel 3, and the distance from one end of the guide groove 31 to the fixed door panel 3 is smaller than the distance from the other end of the guide groove 31 to the fixed door panel 3. The guide post 30 is fixedly connected to the movable door panel 5 and is embedded in the guide groove 31. When the movable door panel 5 makes a linear motion, the guide post 30 on the movable door panel 5 moves toward the position of the fixed door panel 3 under the guidance of the guide groove 31. At this time, the movable door panel 5 moves in two perpendicular directions. The movable door panel 5 presses the sealing ring 11, and finally the movable door panel 5 and the fixed door panel 3 are sealed together by the sealing ring 11.

[0091] A twelfth embodiment: This embodiment differs from the eleventh embodiment in that a return spring II is provided between the movable door panel and the door frame to enable the movable door panel to move toward the fixed door panel.

[0092] The thirteenth embodiment of the present invention is different from the first embodiment in that the structure for the movable door panel to move in a direction perpendicular to the fixed door panel is eliminated.

[0093] The conveyor path sealing and isolation system includes a receiving component, a guide component, a sealing and isolation component, and a lifting component. Once operational, the conveyor path sealing and isolation system is integrated into the frame of an integrated machine, such as a blower-filler-capper. The machine internally divides the chambers, and the sealing and isolation component is integrated into the partition structure that separates the chambers. The conveyor path sealing and isolation system features a chamber on either side of the sealing and isolation component, essentially placing a sealing and isolation component between the two chambers. The sealing and isolation components connect and isolate the chambers. Receivers are distributed within the chambers, each with a conveyor path. Each receiving component includes a receiving turntable, with the conveyor path located at the edge of the receiving turntable. The conveyor paths of the receiving turntables connect and connect to form the overall conveyor path of the conveyor path sealing and isolation system. The overall conveyor path passes through the sealing and isolation component, with the guide component located at the junction. The sealing and isolation component includes a fixed door, a movable door, and a drive element. The fixed door includes a fixed door panel and an inflatable sealing ring. The fixed door panel is mounted on the partition of the machine and sealed to the other. The fixed door panel has a through-hole, and an inflatable sealing ring is mounted on the fixed door panel and distributed around the through-hole. A driver drives the movable door in a linear motion parallel to the fixed door panel. The inflatable sealing ring expands when gas is introduced, but is initially uninflated and non-inflated. The driver provides linear force and can be a linear pneumatic cylinder, oil cylinder, electric cylinder, or a crank-connecting rod-based power assembly. The active portion of the driver, such as the piston rod and rocker arm, is connected to the movable door, while the fixed portion of the driver, such as the cylinder body and motor, can be mounted on the frame or the fixed door. Overall, relative motion between the movable door and the fixed door panel is sufficient.

[0094] Of the adjacent receiving turntables located on either side of the fixed door panel, one receiving turntable has a portion of its edge protruding through a through hole on one side of the fixed door panel, while the other receiving turntable is entirely located on one side of the fixed door panel. The receiving turntable whose portion of its edge protrudes through a through hole on one side of the fixed door panel is designated as receiving turntable I, while the receiving turntable entirely located on one side of the fixed door panel is designated as receiving turntable II. Partial edges of receiving turntable I and partial edges of receiving turntable II are vertically distributed above and below each other. Overall, this stems from the structural design of receiving turntable I being higher than receiving turntable II. Receiving turntable I is directly mounted on the frame via the transmission structure and connected to the transmission structure of the entire machine, while receiving turntable II is mounted on the frame via a lifting component. The lifting component drives the receiving turntable II to move linearly in the vertical direction, thereby adjusting the vertical distance between the adjacent receiving turntables located on both sides of the fixed door panel, namely, receiving turntable I and receiving turntable II. In the initial state, the lifting component places the receiving turntable II at the highest point, and the distance between the receiving turntable I and receiving turntable II is the smallest.

[0095] The lifting components include a transmission assembly and a telescopic assembly. The transmission assembly consists of a drive shaft and a bushing. The bushing is mounted on the frame, with the drive shaft located within the bushing and connected to the bushing via a bearing. After installation, the centerline of the drive shaft is vertical. The drive shaft is connected to the transmission structure of the entire machine. The telescopic assembly includes a loading plate, mounting bushing, support base, and electric linear actuator. The electric linear actuator is mounted on the frame, and the loading plate is mounted on the linear actuator.

[0096] An electric linear actuator consists of a telescopic unit and a motor. The telescopic unit comprises a support sleeve, a lead screw, and a lead screw sleeve. A sliding sleeve is mounted on the outside of the lead screw sleeve, which is movably mounted inside the sleeve. The lead screw sleeve can slide along the centerline of the support sleeve within the support sleeve. The lead screw and the sleeve are threaded together. When the lead screw rotates, the support sleeve moves linearly relative to the support sleeve, achieving the telescopic effect of the entire telescopic unit at the lead screw sleeve. A gear is mounted on the outside of the lead screw.

[0097] The telescopic assembly has three telescopic units, all of which are not on the same straight line, i.e., they are arranged in a triangular pattern. During installation, the support sleeve is fixedly connected to the frame, and the three telescopic units are connected by a chain. The motor is mounted on the frame, and the motor is only connected to the lead screw of one of the telescopic units, thereby being able to synchronously drive the three telescopic units. The lead screws are all fixedly connected to the loading plate, so that when the electric push rod is working, it can raise or lower the height of the loading plate, thus driving the loading plate to move in the vertical direction. The mounting sleeve is fixedly mounted on the loading plate, and the receiving turntable II is fixedly mounted on the top of the support base. The bottom of the support base is cylindrical, and the bottom of the support base is mounted in the mounting sleeve via a bearing, so that the receiving turntable II can rotate on the loading plate. The interior of the support base is a hollow channel structure for accommodating the drive shaft. The centerline of the channel inside the support base coincides with the centerline of the cylindrical bottom portion of the support base. The drive shaft and support base are connected via a flat key, and the support base and drive shaft are slidably connected. Specifically, a keyway is provided inside the support base, located at the edge of the channel, connecting the two. A flat key is provided on the drive shaft, and the end of the drive shaft with the flat key extends into the channel of the support base, with the flat key embedded in the keyway. When the drive shaft rotates, the support base rotates accordingly, and the receiving turntable II rotates; when the receiving turntable II rises or falls, and the support base rises or falls, the flat key slides in the keyway, and the drive shaft slides in the channel of the support base, thereby allowing the receiving turntable II to move linearly in the vertical direction relative to the drive shaft.

[0098] The movable door includes a movable door panel. The movable door panel is movably mounted to the fixed door panel via linear guides, and is in an upright position. In its initial position, the driver retracts, positioning the movable door panel at one end of the fixed door panel. When the driver extends, the movable door panel moves toward the other end of the fixed door panel until it rests in the through-hole in the fixed door panel. The driver pushes and pulls the movable door panel together, maintaining a constant distance between the two panels perpendicular to the fixed door panel.

[0099] The movable door panel is provided with a first escape groove for accommodating a portion of the edge of receiving turntable I protruding from the fixed door panel, and a second escape groove for accommodating a portion of the edge of receiving turntable II. The first escape groove and the second escape groove are both oriented horizontally and in opposite directions, and are not directly connected to each other. Furthermore, to accommodate the different heights of receiving turntables I and II, the first and second escape grooves are at different vertical heights. In the initial state, the movable door panel is away from the through-hole of the fixed door panel, and the portion of the edge of receiving turntable I protruding from the fixed door panel is located in the extension direction of the first escape groove. When receiving turntable II is lowered by the lifting component, the vertical distance between the portion of the edge of receiving turntable II and the portion of the edge of receiving turntable I protruding from the fixed door panel reaches its maximum, and the portion of the edge of receiving turntable II is located in the extension direction of the second escape groove.

[0100] The first escape groove is open at one end to allow the edge of the receiving turntable I protruding from the fixed door panel to fit within the first escape groove after the driver drives the movable door panel. To ensure a tight connection between the fixed and movable door panels, the fixed door panel is provided with a protrusion for fitting into the first escape groove, with an inflatable sealing ring located on the surface of the protrusion. When receiving turntable II descends and the driver pushes the movable door panel toward the other end of the fixed door panel, the edge of receiving turntable II fits within the second escape groove, and the edge of receiving turntable I protruding from the fixed door panel fits within the first escape groove. The inflatable sealing ring is located between the fixed and movable door panels, with a gap between the inflatable sealing ring and the movable door panel. The protrusion on the fixed door panel fits within the first escape groove.

[0101] In this embodiment, the fixed door panel can be sealed and connected to the movable door panel through an inflatable sealing ring, which requires inflating the inflatable sealing ring to make it expand. After expansion, the inflatable sealing ring can be sealed and connected to the movable door panel, and the chambers on both sides of the fixed door panel cannot be connected through the through hole.

[0102] Bottle clamps are installed on the edge of receiving turntable I, and latches are installed on the edge of receiving turntable II. In this embodiment, the guide components include outer guard plate I and inner guard plate I. Both outer guard plate I and inner guard plate I are mounted on a swing mechanism equipped with a cylinder. Both outer guard plate I and inner guard plate I are mounted on the frame in a swinging manner, with the swing direction within the horizontal plane. The cylinder body is mounted on the frame, and the cylinder piston rod is connected to either outer guard plate I or inner guard plate I. The swing mechanism has two cylinders, one for outer guard plate I and the other for inner guard plate I. Initially, outer guard plate I is positioned outside receiving turntable II, with one end extending through a through-hole in the fixed door panel and into the interior of receiving turntable I. Inner guard plate I is positioned inside receiving turntable II. After the swing mechanism drives outer guard plate I and inner guard plate I, outer guard plate I completely detaches from receiving turntable I and positions itself outside, extending into the interior of receiving turntable II. Inner guard plate I moves closer to the center of receiving turntable II. Initially, the entire conveying path lies between the receiving turntable and guard plate, and within the range of motion of the bottle clamp.

[0103] When used for conveying purposes, the chambers on both sides of the fixed door panel are connected through a through-hole. Bottles are fed from receiving turntable II, with the bottle neck embedded in the latch and one side of the bottleneck restricted by outer guard plate I. Receiving turntables I and II both rotate, but in opposite directions. When the bottle is pushed to the through-hole in the fixed door panel, the bottle neck is guided by inner guard plate I and pushed out of the latch of receiving turntable II. Simultaneously, the bottle neck is smoothly clamped by the bottle clamp of receiving turntable I. Depending on actual needs, the bottle can also be conveyed from receiving turntable I to receiving turntable II. However, when the bottle is transferred, it is guided by the end of outer guard plate I, pushed out of the bottle clamp of receiving turntable I, and simultaneously embedded in the latch of receiving turntable II.

[0104] When used for the purpose of isolating a chamber, the fixed door panel is sealed and connected to the movable door panel, and the chambers on both sides of the fixed door panel cannot be connected through the through-hole. First, the receiving turntable II is driven to descend; then, the outer guard plate I and the inner guard plate I are driven to move toward the receiving turntable II, ensuring that the end of the outer guard plate I is separated from the through-hole of the fixed door panel and the inner guard plate I is located on the inner side of the receiving turntable II; then, the movable door panel moves to the position in front of the through-hole of the fixed door panel, that is, between the receiving turntables I and II. Part of the edge of the receiving turntable I is embedded in the first avoidance groove, and part of the edge of the receiving turntable II is embedded in the second avoidance groove. The protrusion on the fixed door panel is embedded in the first avoidance groove, and the inflatable sealing ring is inflated, causing the inflatable sealing ring to be pressed tightly against the movable door panel. Finally, the fixed door panel is sealed and connected to the movable door panel, and the through-hole of the fixed door panel is closed by the movable door panel.

[0105] The fourteenth embodiment. The difference between this embodiment and the thirteenth embodiment is that the outer guard plate I and the inner guard plate I are directly fixed on the frame, and the operation of isolating the two chambers is carried out by disassembling and assembling the outer guard plate I and the inner guard plate I.

[0106] The fifteenth embodiment is different from the thirteenth embodiment in that the edge of the receiving turntable I and the edge of the receiving turntable II are both provided with a snap-on. The guide component includes two guard plates, one guard plate corresponds to the receiving turntable I and the other guard plate corresponds to the receiving turntable II. Both guard plates are fixedly mounted on the frame. One of the guard plates is located on the outside of the receiving turntable I and one end of the guard plate extends into the inner side of the adjacent receiving turntable II, and the other guard plate is located on the outside of the receiving turntable II and one end of the guard plate extends into the inner side of the adjacent receiving turntable I. Both guard plates pass through the through hole of the fixed door panel. The overall conveying path is located between the receiving turntable and the guard plate. The operation of isolating the two chambers is participated in by disassembling and assembling the guard plates.

[0107] The sixteenth embodiment is different from the fifteenth embodiment in that one guard plate is an integral structure, and the other guard plate is changed from an integral structure to a split structure. Specifically, the split guard plate includes a limit plate I and a guide plate I. The split guard plate corresponds to the receiving turntable I. The limit plate I of the split guard plate is located on the outside of the receiving turntable I, one end of the guide plate I is located on the inside of the receiving turntable II, and the other end of the guide plate I passes through the through hole of the fixed door panel and is continuously distributed with the limit plate I. The guide plate I is mounted on the swinging mechanism; the guard plate on the outside of the receiving turntable II is also mounted on the swinging mechanism. The limit plate I is located on the other side of the fixed door panel as a whole, and it does not pass through the through hole of the fixed door panel. The limit plate I participates in the operation of isolating the two chambers by swinging toward the inside of the receiving turntable II and disengaging it from the through hole of the fixed door panel.

[0108] The seventeenth embodiment differs from the thirteenth embodiment in that bottle clamps are provided at the edges of both receiving turntables I and II. The guide assembly comprises two guard plates, both located on the inner sides of the receiving turntables, namely, one guard plate located on the inner side of receiving turntable I and the other on the inner side of receiving turntable II. Both guard plates are fixedly mounted to the frame. The entire conveying path is within the range of motion of the bottle clamps. The two chambers are isolated by removing and installing the guard plates.

[0109] The eighteenth embodiment is different from the seventeenth embodiment in that the guard plate is mounted on the swing mechanism. The guard plate is swung to be positioned further inward to participate in the operation of isolating the two chambers.

[0110] The nineteenth embodiment differs from the thirteenth embodiment in that a bayonet is provided on the edge of the receiving turntable I, and a bottle clamp is provided on the edge of the receiving turntable II.
