Description

Technical Field

[0001] This application relates to the technical field of gas tanker manufacturing, and in particular to an apparatus and method for winding and forming the insulation layer of an LNG vehicle-mounted cylinder. Background Technology

[0002] Gas tankers on tank trucks typically consist of an inner liner and an outer liner. The inner liner is fixed to the inside of the outer liner by welding. For effective heat insulation, the end faces and circumferential sides of the inner liner need to be wrapped with aluminum foil insulation material. This aluminum foil insulation material comes in two types: the inner layer is a non-flame-retardant material, mainly used to insulate against heat radiation and temperature conduction, while the outer layer is a flame-retardant material, whose main function is to prevent the high temperature from burning the non-flame-retardant material of the inner liner during the welding process between the inner and outer liners.

[0003] Currently, the common method for wrapping aluminum foil insulation material is as follows: First, the inner liner is rotated and mounted on an inner liner rotation support frame, which is equipped with a motor to drive the inner liner to rotate. A roller support frame is set on one side of the inner liner rotation support frame, supporting rollers for winding the aluminum foil insulation material. During operation, the operator fixes the head of the aluminum foil on the roller to the surface of the inner liner using aluminum foil tape, then starts the motor to rotate the inner liner, thereby gradually winding the aluminum foil around the circumference of the inner liner. For the end face of the inner liner, a separate sheet of aluminum foil is required, which is manually applied using aluminum foil tape to cover the entire end face area.

[0004] However, significant operational challenges exist in attaching the aluminum foil to the inner liner's end face. Due to the large area of ​​the inner liner's end face, it is crucial to ensure the aluminum foil is flat and free of air bubbles during attachment. Furthermore, the rotating support structure of the inner liner directly obstructs the operating space, requiring workers to carefully avoid the rotating support structure during attachment. This not only increases the complexity of the process but also easily leads to uneven attachment of the aluminum foil. These factors make the attachment work cumbersome and time-consuming, significantly reducing overall production efficiency. Summary of the Invention

[0005] To address the issues of limited operating space, uneven application, and low production efficiency when manually attaching aluminum foil sheets to the end face of LNG tanker liners, this application provides an apparatus and method for winding and forming the insulation layer of LNG vehicle-mounted cylinders.

[0006] The technical solution provided in this application for an LNG vehicle-mounted bottle insulation layer winding and forming apparatus and method adopts the following: An apparatus and method for winding and forming the insulation layer of an LNG vehicle-mounted bottle includes an inner liner rotating support frame, an aluminum foil feeding mechanism, a carrying component, a support frame moving component, and an aluminum foil support frame. The inner liner rotating support frame, aluminum foil feeding mechanism, carrying component, support frame moving component, and aluminum foil support frame are all disposed on the ground. The carrying component is located below the inner liner and is used to support the inner liner. The end of the inner liner is disposed on the inner liner rotating support frame. The support frame moving component is located on one side of the carrying component and is used to move the inner liner rotating support frame. The aluminum foil support frame is located on one side of the inner liner rotating support frame. The aluminum foil feeding mechanism is used to feed aluminum foil from the aluminum foil support frame onto the inner liner. The aluminum foil feeding mechanism includes a feeding moving component, a feeding component, and a rotating component. The rotating component is disposed on the ground, the feeding moving component is disposed on the rotating component, and the feeding component is disposed on the feeding moving component.

[0007] By adopting the above technical solution, this solution constructs a complete automated bonding system by setting up an inner liner rotating support frame, an aluminum foil feeding mechanism, a carrier component, a support frame moving component, and an aluminum foil support frame. This device achieves fully automated operation of the entire process of aluminum foil bonding, from storage and transportation to precise bonding to the inner liner end face, replacing the previously used method that relied entirely on manual bonding. The inner liner rotating support frame and the carrier component work together to provide stable rotational support and support for the inner liner, ensuring the stability of the inner liner position during aluminum foil winding and end face bonding. The support frame moving component drives the inner liner rotating support frame to move, freeing up operating space for the feeding mechanism and fundamentally avoiding interference of the inner liner rotating support frame structure with the bonding operation. The aluminum foil feeding mechanism, as the core actuator, completes the automatic suction, transfer, and pressing of the aluminum foil.

[0008] Preferably, the feeding assembly includes a feeding support frame, a feeding support rod, a suction block, a feeding drive motor, a feeding drive screw, a feeding screw sleeve, and an angle adjustment connecting rod. The feeding support frame is disposed at the upper end of the feeding moving assembly. The feeding support rod is rotatably disposed on the feeding support frame. The suction block is rotatably disposed at the end of the feeding support rod away from the feeding support frame. The feeding drive motor is disposed on the feeding support frame. The feeding drive screw is coaxially disposed on the output shaft of the feeding drive motor. The feeding screw sleeve is sleeved on the feeding drive screw. The angle adjustment connecting rod is disposed between the feeding support rod and the feeding screw sleeve.

[0009] By adopting the above technical solution, this solution achieves centralized and synchronous control of the swing of the feeding support rods through a linkage mechanism consisting of a feeding drive motor, a feeding screw sleeve, and multiple angle-adjusting connecting rods. This design allows multiple feeding support rods to coordinately converge or open based on a single power source, thereby driving multiple suction blocks installed at their ends to open and close synchronously. This linkage method ensures the positional synchronization and motion consistency of each suction block during operation, providing reliable motion assurance for the stable adsorption of aluminum foil and uniform pressing on the arc-shaped end face of the inner liner.

[0010] Preferably, the feeding support rod is provided with a limiting component, which includes a slider and a spring. The slider is disposed on the feeding support rod, one end of the spring is disposed on the feeding support rod, and the other end of the spring is disposed on the end of the slider away from the suction block. The end of the slider away from the spring abuts against the suction block.

[0011] By adopting the above technical solution, the limiting component, through the cooperation of the slider and the spring, provides elastic constraint and automatic reset function for the relative rotation between the suction block and the feeding support rod. This allows the suction block to adaptively deflect according to the arc contour of the end face when pressing against the inner liner, increasing the contact area and improving the pressing effect; after completing the pressing and disengaging contact, it can automatically return to the preset initial posture under the action of the spring, preparing for the next suction of aluminum foil, thus improving the reliability and consistency of the operation.

[0012] Preferably, the suction block has a suction cavity, and the end of the suction block away from the feeding support rod has a suction hole that communicates with the suction cavity; the suction block is provided with an air pipe that communicates with the suction cavity, and the end of the air pipe is provided on an air pump.

[0013] By adopting the above technical solution, the suction block achieves negative pressure adsorption of aluminum foil by opening suction chambers and suction holes inside and connecting air pipes and air pumps. This design provides a non-contact gripping method, avoiding damage to the soft aluminum foil that may be caused by mechanical clamping, and ensuring the flatness of the aluminum foil during transportation. The rubber cotton at the end further increases cushioning and protection, preventing scratches on the aluminum foil surface.

[0014] Preferably, the bearing assembly includes a bearing cylinder and a bearing roller, the bearing cylinder being vertically disposed on the ground, and the bearing roller being horizontally disposed at the end of the piston rod of the bearing cylinder.

[0015] By adopting the above technical solution, the support component uses multiple support cylinders to drive the support rollers to rise and fall, forming an arc-shaped support line that matches the contour of the inner liner's circumferential sidewall. This design can stably support the inner liner according to process requirements when winding aluminum foil or applying end faces, providing a stable working foundation for the entire application process.

[0016] Preferably, the support frame moving assembly includes a first moving drive motor and a first screw. The inner liner rotating support frame is slidably disposed on the ground. The first moving drive motor is horizontally disposed on the ground. The first screw is coaxially disposed on the output shaft of the first moving drive motor. The first screw is threadedly connected to the inner liner rotating support frame.

[0017] By adopting the above technical solution, the support frame moving assembly drives the first screw to rotate via the first moving drive motor, converting the rotational motion into linear displacement of the inner liner rotating support frame. This design directly addresses the problem in the prior art where the inner liner rotating support frame structure obstructs the end face attachment operation space, providing ample and unobstructed working area for the aluminum foil feeding mechanism through controllable movement.

[0018] Preferably, a rotary drive motor is provided on the inner liner rotating support frame, the output shaft end of the rotary drive motor faces the inner liner, a prism is coaxially provided on the output shaft of the rotary drive motor, and a sliding sleeve is sleeved on the prism; a rotary support rod is provided laterally at the end of the inner liner, and the rotary support rod is inserted into the sliding sleeve; the rotary support rod is positioned on the sliding sleeve by a positioning bolt.

[0019] By adopting the above technical solution, the inner liner rotating support frame, through the inclusion of a rotary drive motor, a prism, and a sliding sleeve fitted onto the prism, which interlocks with the rotating support rod at the end of the inner liner, achieves quick clamping and power connection of the inner liner. The interlocking structure of the rotating support rod and the sliding sleeve, combined with axial fixation using positioning bolts, makes the installation and disassembly of the inner liner simple and quick. The power of the rotary drive motor is transmitted to the sliding sleeve through the prism, thereby driving the rotating support rod, which is interlocked with the sliding sleeve, and the entire inner liner to rotate. This design provides a stable and reliable rotary driving force for the inner liner when wrapping aluminum foil around its circumferential side.

[0020] Preferably, the rotating assembly includes a rotating support base, a deflection drive motor, and a rotating platform. The rotating support base is vertically mounted on the ground, and the rotating platform is rotatably mounted on the upper end of the rotating support base. The lower end of the rotating platform extends into the rotating support base, and an annular rack is provided at the lower end of the rotating platform. The deflection drive motor is vertically mounted inside the rotating support base, with the end of the output shaft of the deflection drive motor facing upward. A drive gear is coaxially mounted on the output shaft of the deflection drive motor, and the drive gear meshes with the annular rack.

[0021] By adopting the above technical solution, the rotating component drives the rotating platform to rotate horizontally through the meshing transmission of the deflection drive motor, drive gear, and ring rack. This design allows the feeding moving component and the feeding component installed on the rotating platform to be adjusted in the horizontal plane, thereby flexibly aligning the suction block with the aluminum foil support frame to pick up aluminum foil, or aligning it with the inner end face for attaching operations, increasing the operational flexibility of the device.

[0022] Preferably, the feeding moving assembly further includes a second moving drive motor and a second screw. The second moving drive motor is laterally arranged on the rotating platform, the lower end of the feeding support frame is slidably connected to the rotating platform, the second screw is coaxially arranged on the output shaft of the second moving drive motor, and the second screw is also threadedly connected to the feeding support frame.

[0023] By adopting the above technical solution, the feeding moving assembly drives the second screw to rotate via the second moving drive motor, thereby causing the feeding support frame to move linearly. This design enables the overall position adjustment of the feeding assembly relative to the rotating platform, thereby controlling the forward and backward position of the suction block when suctioning and pressing aluminum foil sheets.

[0024] Preferably, the rotary drive motor is further provided with an infrared beam sensor, which includes a transmitter and a receiver. The transmitter is disposed on the housing of the rotary drive motor, and a detection disk is coaxially disposed on the output shaft of the rotary drive motor. The receiver is disposed on the end face of the detection disk facing the housing of the rotary drive motor.

[0025] By adopting the above technical solution, the combination of the infrared beam sensor and the detection disk provides a non-contact detection method for the rotation count of the rotary drive motor. Through counting pulse signals, the control system can accurately control the rotation count of the inner liner, thereby accurately controlling the number of wrapping turns of non-flame-retardant and flame-retardant aluminum foil on the circumferential side of the inner liner, realizing the automation of the wrapping process.

[0026] In summary, this application includes the following beneficial technical effects: 1. A complete automated foil application system was constructed by setting up an inner liner rotating support frame, an aluminum foil feeding mechanism, a carrier component, a support frame moving component, and an aluminum foil support frame. This device achieves fully automated operation of the entire process of aluminum foil application, from storage and transportation to precise application to the inner liner end face, replacing the previous method that relied entirely on manual application. The inner liner rotating support frame and the carrier component work together to provide stable rotational support and support for the inner liner, ensuring the stability of the inner liner position during aluminum foil winding and end face application. The support frame moving component can drive the inner liner rotating support frame to move, making room for the feeding mechanism and fundamentally avoiding interference of the inner liner rotating support frame structure with the application operation. The aluminum foil feeding mechanism, as the core actuator, completes the automatic suction, transfer, and pressing of the aluminum foil.

[0027] 2. Driven by a feeding drive motor, and via a linkage mechanism consisting of a feeding drive screw, a feeding screw sleeve, and multiple angle-adjustable connecting rods, centralized synchronous control of the oscillation of the feeding support rods is achieved. This design allows multiple feeding support rods to coordinately converge or open based on a single power source, thereby driving multiple suction blocks installed at their ends to open and close synchronously. This linkage method ensures the positional synchronization and motion consistency of each suction block during operation, providing reliable motion assurance for the stable adsorption of aluminum foil and uniform pressing on the curved end face of the inner liner.

[0028] 3. The limiting component, through the cooperation of the slider and the spring, provides elastic constraint and automatic reset function for the relative rotation between the suction block and the feeding support rod. This allows the suction block to adaptively deflect according to the arc contour of the end face when pressing against the inner liner, increasing the contact area and improving the pressing effect; after completing the pressing and disengaging contact, it can automatically return to the preset initial posture under the action of the spring, preparing for the next suction of aluminum foil, thus improving the reliability and consistency of the operation.

[0029] 4. The suction block, with its internal suction chamber and suction holes connected to an air tube and air pump, achieves negative pressure adsorption of the aluminum foil. This design provides a non-contact gripping method, avoiding potential damage to the soft aluminum foil caused by mechanical clamping and ensuring the flatness of the aluminum foil during transport. Rubber pads at the ends further enhance cushioning and protection, preventing scratches on the aluminum foil surface. Attached Figure Description

[0042] The following is in conjunction with the appendix Figure 1-11 This application will be described in further detail.

[0043] This application discloses an apparatus and method for winding and forming the insulation layer of an LNG vehicle-mounted cylinder, referring to... Figures 1-2 The system includes an inner liner rotating support frame 1, an aluminum foil feeding mechanism 2, a bearing assembly 3, a support frame moving assembly 4, and an aluminum foil support frame 5. All components are mounted on the ground. The bearing assembly 3 supports the inner liner 6, which is horizontally positioned.

The aluminum foil support frame 5 is located on one side of the inner liner rotating support frame 1, and the aluminum foil feeding mechanism 2 is located on one side of the aluminum foil support frame 5. The aluminum foil feeding mechanism 2 is used to attach aluminum foil 7 from the aluminum foil support frame 5 to the inner liner 6.

[0044] Reference Figures 1-3A first roller support frame 9 and a second roller support frame 10 are vertically fixed to the ground. Both the first roller support frame 9 and the second roller support frame 10 are located on one side of the inner liner rotating support frame 1. A first unwinding roller is rotatably connected to the first roller support frame 9, and a non-flame-retardant aluminum foil roll 91 is sleeved on the first unwinding roller. The axis of the first unwinding roller is parallel to the length direction of the inner liner 6. The second roller support frame 10 is also located below the first roller support frame 9. In this embodiment, two second roller support frames 10 are arranged side by side along the length direction of the inner liner 6. A second unwinding roller is rotatably connected to each second roller support frame 10. The length direction of each second unwinding roller is parallel to the length direction of the inner liner 6. A flame-retardant aluminum foil roll 101 is sleeved on each second unwinding roller, and the combined length of the two flame-retardant aluminum foil rolls 101 is greater than the length of the inner liner 6. Specifically, the ends of the two flame-retardant aluminum foil rolls 101 that are far apart from each other extend beyond both ends of the inner liner 6.

[0045] Reference Figure 1 , Figure 4 and Figure 5 In this embodiment, the inner liner 6 is a closed cylinder with a cavity inside. A rotating support rod 61 is fixedly and coaxially connected to each end of the inner liner 6. Each rotating support rod 61 has a first through hole coaxially formed, and both first through holes communicate with the inner cavity of the inner liner 6. In this embodiment, two sets of support frame moving assemblies 4 are provided, both sets of which are installed on the ground and located at both ends of the inner liner 6. Two inner liner rotating support frames 1 are provided, each mounted on one of the two support frame moving assemblies 4, with a one-to-one correspondence between the inner liner rotating support frame 1 and the support frame moving assembly 4. This embodiment uses one of the inner liner rotating support frames 1 as an example. A rotary drive motor 11 is fixedly connected to the upper end of the inner liner rotating support frame 1. The output shaft of the rotary drive motor 11 faces the end of the inner liner 6, and the axis of the output shaft of the rotary drive motor 11 is parallel to the axis of the inner liner 6. A prism 111 is coaxially fixedly connected to the output shaft of the rotary drive motor 11. A sliding sleeve 1111 is fitted onto the prism 111. The sliding sleeve 1111 is a cylindrical tube. The end of the sliding sleeve 1111 near the inner liner 6 is inserted into and engaged with the rotating support rod 61 on the inner liner 6. The sliding sleeve 1111 is positioned on the rotating support rod 61 by a positioning bolt 12. The axis of the positioning bolt 12 is perpendicular to the axis of the rotating support rod 61.

[0046] Reference Figure 1 , Figure 4 and Figure 5The supporting component 3 is located below the inner liner 6. Three sets of supporting components 3 are arranged on the ground along a direction perpendicular to the axis of the inner liner 6. One set of supporting components 3 is located directly below the inner liner 6, and the other two sets are located on either side of the supporting component 3 directly below the inner liner 6. This embodiment uses the supporting component 3 located directly below the inner liner 6 as an example. The supporting component 3 includes two supporting cylinders 31 and a supporting support frame 32. The two supporting cylinders 31 are vertically fixed to the ground side-by-side along the axis of the inner liner 6, with the piston rod ends of the cylinders facing the inner liner 6. The lower end of the supporting support frame 32 is fixedly connected to the piston rod ends of the two cylinders. A supporting roller 321 is rotatably connected to the upper end of the supporting support frame 32, and the axis of the supporting roller 321 is parallel to the axis of the inner liner 6. In this embodiment, the arrangement of the three supporting rollers 321 forms a continuous arc. The contour of the arc matches the contour of the circumferential sidewall of the inner liner 6, allowing the bearing roller 321 to conform to the circumferential sidewall of the inner liner 6 to provide uniform support.

[0047] Reference Figures 1-2 A cutting assembly 13 is also installed on the ground. The cutting assembly 13 is located on one side of the inner liner 6. The cutting assembly 13 includes a cutting cylinder 131, a cutting plate 132, a sliding support rod 133, a cutting support frame 134, and a support roller 135. The cutting support frame 134 is vertically fixed to the ground and located between the inner liner 6 and the first roller support frame 9. The support roller 135 is rotatably connected to the cutting support frame 134. The axis of the support roller 135 is parallel to the axis of the inner liner 6. The support roller 135 is located on one side of the inner liner 6. The cutting cylinder 131 is vertically fixedly connected to the upper end of the cutting support frame 134. The end of the piston rod of the cutting cylinder 131 faces downward. The cutting plate 132 is vertically fixedly connected to the end of the piston rod of the cutting cylinder 131. A row of cutting teeth 1321 is fixedly connected to the lower end of the cutting plate 132. A sliding support rod 133 is vertically fixedly connected to the upper end of the cutting plate 132. The sliding support rod 133 is slidably engaged with the cutting support frame 134. When the cutting assembly 13 is in a non-working state, the cutting plate 132 is located above the inner liner 6.

[0048] Reference Figure 1 , Figure 2 and Figure 6When performing the aluminum foil winding operation, firstly, non-flame-retardant aluminum foil is wound around the surface of the inner liner 6 for 7 turns. Then, the wound non-flame-retardant aluminum foil is cut by the cutting component 13. Next, flame-retardant aluminum foil is wound around the surface of the inner liner 6 for one turn, and then cut by the cutting component 13 again. During this process, both ends of the flame-retardant aluminum foil extend beyond the corresponding ends of the inner liner 6. Before the winding operation begins, both the non-flame-retardant and flame-retardant aluminum foils are guided by the support roller 135 and then fixed to the surface of the inner liner 6. Specifically, the winding operation adopts a step-by-step process, sequentially winding the non-flame-retardant and flame-retardant aluminum foils around the surface of the inner liner 6. Specifically, the inner liner 6 rotates under the drive of the rotary drive motor 11, continuously winding the non-flame-retardant aluminum foil around the circumference of the inner liner 6. When 7 turns are reached, the rotary drive motor 11 stops working. Subsequently, the cutting assembly 13 is activated, and the cutting cylinder 131 drives the cutting plate 132 and cutting teeth 1321 to move downwards, cutting the section of the non-flame-retardant aluminum foil roll that has been wound. Then, the worker uses aluminum foil tape to fix the non-flame-retardant aluminum foil to the inner liner. Next, the flame-retardant aluminum foil is wound: the flame-retardant aluminum foil is wound on top of the non-flame-retardant aluminum foil layer, and the inner liner 6 rotates again, wrapping the flame-retardant aluminum foil around the outer surface of the non-flame-retardant aluminum foil layer. The length of the wound flame-retardant aluminum foil layer extends beyond the two ends of the inner liner 6 body. When the flame-retardant aluminum foil has been wound one turn, the inner liner 6 stops rotating. The cutting assembly 13 is activated again, and the cutting cylinder 131 drives the cutting plate 132 to move downwards to cut the flame-retardant aluminum foil roll. Then, the worker uses aluminum foil tape to adhere and fix the flame-retardant aluminum foil to the surface of the non-flame-retardant aluminum foil, while the portion of the flame-retardant aluminum foil extending beyond the two ends of the inner liner remains unfixed.

[0049] Reference Figure 5 , Figure 7 and Figure 8This device is also equipped with a controller (not shown in the figure), which is existing technology and will not be described in detail here. A detection disk 113 is coaxially fixedly connected to the output shaft of the rotary drive motor 11. The detection disk 113 is located between the prism 111 and the housing of the rotary drive motor 11. An infrared beam sensor 112 is fixedly connected to the rotary drive motor 11 and is communicatively connected to the controller. The infrared beam sensor 112 includes a transmitter 1121 and a receiver 1122. The transmitter 1121 is fixedly connected to the housing of the rotary drive motor 11, and the emission port of the transmitter 1121 faces the detection disk 113. The receiver 1122 is fixedly connected to the end face of the detection disk 113 near the housing of the rotary drive motor 11, and the receiving port of the receiver 1122 faces the housing of the rotary drive motor 11. The detection disk 113 rotates synchronously with the output shaft of the rotary drive motor 11. The transmitter 1121, fixed to the housing, continuously emits infrared signals. The receiver 1122, fixed to the detection disk 113, moves in a circular motion with the disk. When it reaches a position opposite to the transmitter 1121, the receiver 1122 receives an infrared signal and generates a pulse signal. Each rotation of the detection disk 113 completes one revolution, aligning the receiver 1122 with the transmitter 1121 and generating one pulse. The controller counts the pulse signals; one pulse corresponds to one rotation of the inner liner 6. In the non-flame-retardant aluminum foil winding operation, the controller determines that the winding count has reached 7 turns when it has received a total of 7 pulses, and the rotary drive motor 11 stops working. Similarly, in the flame-retardant aluminum foil winding operation, the controller determines that the winding count has reached one turn when it has received a total of one pulse, and the rotary drive motor 11 stops working.

[0050] Reference Figures 1-2 This embodiment uses one set of support frame moving components 4 and the inner liner rotating support frame 1 installed on the support frame moving components 4 as examples for description. The support frame moving components 4 include a first moving drive motor 41, a first screw 42, and a sliding rod 43. The first moving drive motor 41 is horizontally fixedly connected to the ground, and the axis of the output shaft of the first moving drive motor 41 is perpendicular to the axis of the inner liner 6. The first screw 42 is coaxially fixedly connected to the end of the output shaft of the first moving drive motor 41. A first support for supporting the rotation of the first screw 42 is fixedly connected to the ground. The sliding rod 43 is fixedly connected to the ground through a second support, and the axis of the sliding rod 43 is parallel to the axis of the first screw 42. The lower end of the inner liner rotating support frame 1 is slidably engaged with the sliding rod 43, and the lower end of the inner liner rotating support frame 1 is also threadedly engaged with the first screw 42.

[0051] Reference Figure 1 , Figure 2 and Figure 8In this embodiment, two sets of aluminum foil feeding mechanisms 2 are provided, located at both ends of the inner liner 6, and two inner liner rotating support frames 1 are located between one aluminum foil feeding mechanism 2 and the inner liner 6. Two aluminum foil support frames 5 are provided, both vertically fixed to the ground, and located on one side of one aluminum foil feeding mechanism 2. This embodiment uses one set of aluminum foil feeding mechanisms 2 and the aluminum foil support frame 5 that cooperates with this set of aluminum foil feeding mechanisms 2 for feeding as an example. Before the aluminum foil 7 on the aluminum foil support frame 5 is attached to the inner liner 6 by the aluminum foil feeding mechanism 2, the inner liner rotating support frame 1 is moved away from the cutting component 13 by the support frame moving component 4. This movement is to avoid interference between the aluminum foil feeding mechanism 2 and the inner liner rotating support frame 1 during the feeding process. Specifically, the workers first remove the positioning bolt 12, disengaging the sliding sleeve 1111 from the rotating support rod 61 of the inner liner 6. Then, the first moving drive motor 41 starts and drives the first screw 42 to rotate. The rotational motion of the first screw 42 is converted into linear motion of the inner liner rotating support frame 1 along the axis of the sliding rod 43 through threaded engagement, thereby driving the inner liner rotating support frame 1 to move away from the cut-off assembly 13.

[0052] Reference Figure 1 , Figure 9 and Figure 10 The aluminum foil feeding mechanism 2 includes a feeding moving assembly 21, a feeding assembly 22, and a rotating assembly 23. The rotating assembly 23 is mounted on the ground, the feeding moving assembly 21 is mounted on the rotating assembly 23, and the feeding assembly 22 is mounted on the feeding moving assembly 21. The rotating assembly 23 includes a rotating support base 231, a deflection drive motor 232, and a rotating platform 233. The rotating support base 231 is vertically fixed on the ground. The rotating platform 233 is rotatably connected to the upper end of the rotating support base 231, and a ring rack 2331 is fixedly connected to the lower end of the rotating platform 233, extending into the rotating support base 231. The deflection drive motor 232 is vertically fixedly connected to the rotating support base 231, with the end of the output shaft of the deflection drive motor 232 facing upwards. A drive gear 2321 is coaxially fixedly connected to the end of the output shaft of the deflection drive motor 232, and the drive gear 2321 meshes with the ring rack 2331. The feeding moving assembly 21 includes a second moving drive motor 211 and a second screw 212. The second moving drive motor 211 is horizontally fixedly connected to the side wall of the rotating platform 233. A sliding support groove 2332 is provided at the upper end of the rotating platform 233. The output shaft of the second moving drive motor 211 extends into the sliding support groove 2332. The second screw 212 is coaxially fixedly connected to the end of the output shaft of the second moving drive motor 211. The second screw 212 is located in the sliding support groove 2332. A third support for supporting the rotation of the second screw 212 is fixedly connected to the bottom of the sliding support groove 2332.

[0053] Reference Figure 1 , Figure 9 and Figure 10 The rotating component 23 drives the feeding moving component 21 and the feeding component 22 mounted on the feeding moving component 21 to rotate horizontally. Specifically, the deflection drive motor 232 starts, and the output shaft of the deflection drive motor 232 drives the drive gear 2321 to rotate. The drive gear 2321 meshes with the annular rack 2331 fixed at the lower end of the rotating platform 233, thereby converting the rotational motion of the drive gear 2321 into the rotation of the rotating platform 233 around a vertical line. This rotation allows the feeding component 22 to adjust its horizontal angle. The second moving drive motor 211 starts, driving the second screw 212 to rotate. The rotational motion of the second screw 212 is converted into the linear motion of the sliding support block 2211 through the threaded engagement with the sliding support block 2211. The sliding support block 2211 slides in the sliding support groove 2332, driving the feeding support frame 221 and the feeding component 22 mounted on the feeding support frame 221 to move as a whole, thereby adjusting the position of the feeding component 22.

[0054] Reference Figures 9-10 The feeding assembly 22 includes a feeding support frame 221, three feeding support rods 222, a suction block 223, a feeding drive motor 224, a feeding drive screw 225, a feeding screw sleeve 226, and three angle adjustment connecting rods 227. The lower end of the feeding support frame 221 is in close contact with the upper end surface of the rotating platform 233. A sliding support block 2211 is fixedly connected to the lower end of the feeding support frame 221. The sliding support block 2211 extends into the sliding support groove 2332, and the sliding support block 2211 is also threadedly engaged with the second screw 212. The feeding drive motor 224 is horizontally fixedly connected to the feeding support frame 221. The feeding drive screw 225 is coaxially fixedly connected to the output shaft of the feeding drive motor 224. One end of each of the three feeding support rods 222 is rotatably connected to the feeding support frame 221 through a first rotating shaft. The three feeding support rods 222 are evenly arranged in a circle on the feeding support frame 221. Each end of the three feeding support rods 222 away from the feeding support frame 221 is rotatably connected to a suction block. 223. One end of each of the three angle-adjusting connecting rods 227 is rotatably connected to the feeding screw sleeve 226 via a second rotating shaft. The other end of each of the three angle-adjusting connecting rods 227 is rotatably connected to the side wall of each of the three feeding support rods 222 near the feeding drive screw 225 via a third rotating shaft. The three angle-adjusting connecting rods 227 are evenly arranged in a circle on the feeding screw sleeve 226, and each of the three angle-adjusting connecting rods 227 corresponds one-to-one with the three feeding support rods 222. The axes of the first rotating shaft, the second rotating shaft, and the third rotating shaft between each feeding support rod 222 and the feeding screw sleeve 226 are parallel to each other.

[0055] Reference Figures 9-10 When the feeding drive motor 224 operates, the feeding drive screw 225 rotates accordingly. Through the rotational connection between the angle adjustment connecting rod 227 and the feeding support rod 222, the feeding sleeve 226 is restricted to moving only along the axial direction of the feeding drive screw 225. During the axial movement of the feeding sleeve 226, it drives the corresponding feeding support rod 222 to swing around the first rotation axis via the various angle adjustment connecting rods 227 connected to it. Since the three feeding support rods 222 are evenly arranged circumferentially, and each angle adjustment connecting rod 227 is rotatably connected to each feeding support rod 222, the linear motion of the feeding sleeve 226 is synchronously converted into the coordinated swinging of the three feeding support rods 222. This swinging causes the ends of the three feeding support rods 222 that are away from the feeding support frame 221 to simultaneously move closer together or further apart, thereby achieving the gathering or opening movement of the suction block 223.

[0056] Reference Figures 9-11 In this embodiment, each feeding support rod 222 is equipped with a limiting component 8, which is used to limit the deflection angle of the suction block 223. This embodiment takes one feeding support rod 222, the upper limiting component 8 installed on the feeding support rod 222, and the suction block 223 rotatably connected to the feeding support rod 222 as an example for description. The feeding support rod 222 is fixedly composed of a first support rod 2221 and a second support rod 2222, and there is a certain angle between the first support rod 2221 and the second support rod 2222. The end of the first support rod 2221 is rotatably connected to the feeding support frame 221, and the suction block 223 is rotatably connected to the end of the second support rod 2222 through a fourth rotating shaft, and the axis of the fourth rotating shaft is parallel to the axis of the first rotating shaft. The limiting components 8 are mounted on the second support rod 2222. Two sets of limiting components 8 are provided, symmetrically arranged on the second support rod 2222 about the fourth rotation axis between the suction block 223 and the second support rod 2222. This embodiment uses one set of limiting components 8 as an example for explanation. The limiting component 8 includes a slider 81 and a spring 82. The slider 81 is slidably connected to the second support rod 2222, and its length direction is parallel to the length direction of the second support rod 2222. One end of the spring 82 is fixedly connected to the second support rod 2222, and the other end of the spring 82 is fixedly connected to the slider 81, with its length direction parallel to the length direction of the slider 81. The end of the slider 81 away from the spring 82 abuts against the side wall of the suction block 223. The function of the two sets of limiting components 8 is to keep the length direction of the suction block 223 perpendicular to the length direction of the limiting rod when no external force is applied.

[0057] Reference Figures 9-11The suction block 223 has a suction cavity 2232 inside. A suction hole 2231 is formed on the side wall of the suction block 223 away from the feeding support rod 222. The axis of the suction hole 2231 is perpendicular to the length direction of the suction block 223, and the suction hole 2231 communicates with the suction cavity 2232. An air pipe 2233 is fixedly connected to the side wall of the suction block 223, communicating with the suction cavity 2232. The end of the air pipe 2233 is fixedly connected to an air pump (not shown in the figure). A rubber cotton is fixedly connected to the end of the suction block 223 away from the feeding support rod 222. A second through hole is formed on the rubber cotton, and this second through hole is aligned with the suction hole 2231 on the suction block 223.

[0058] Reference Figure 6 An aluminum foil support rod 51 is horizontally fixedly connected to the aluminum foil support frame 5. The length direction of the aluminum foil support rod 51 is perpendicular to the axis of the inner liner 6. Multiple aluminum foil sheets 7 are sleeved on the aluminum foil support rod 51. The aluminum foil sheets 7 are divided into non-flame-retardant aluminum foil sheets and flame-retardant aluminum foil sheets. The non-flame-retardant aluminum foil sheets and flame-retardant aluminum foil sheets are arranged on the aluminum foil support rod 51 in the following order: one non-flame-retardant aluminum foil sheet is alternated with one flame-retardant aluminum foil sheet.

[0059] Reference Figure 5 , Figure 6 and Figure 10The end face of the inner liner 6 is an arc surface that bulges away from the inner cavity of the inner liner 6. After non-flame-retardant aluminum foil and flame-retardant aluminum foil are sequentially wound around the circumferential side wall of the inner liner 6, the aluminum foil feeding mechanism 2 presses the flame-retardant aluminum foil that extends beyond the end of the inner liner 6 onto the arc surface. The specific operation process is as follows: First, the rotating component 23 is activated, driving the feeding moving component 21 and the feeding component 22 mounted on the rotating component 23 to rotate as a whole, so that the end of the suction block 223 of the feeding component 22 away from the feeding support rod 222 faces the inner liner 6. Then, the feeding drive motor 224 starts, driving the feeding drive screw 225 to rotate in the forward direction, and then through the transmission of the feeding screw sleeve 226, the angle adjustment connecting rod 227 and the feeding support rod 222, the multiple suction blocks 223 are spread out apart from each other. Subsequently, the feeding moving component 21 operates, driving the feeding component 22 to gradually move towards the inner liner 6 until the suction block 223 moves to the area above the arc-shaped end face of the inner liner 6, and the overall position of the suction block 223 does not exceed the edge of the end face of the inner liner 6. Then, the feeding drive motor 224 reverses, driving the feeding drive screw 225 to rotate in the opposite direction. Through the linkage of the feeding screw sleeve 226, the angle adjustment connecting rod 227, and the feeding support rod 222, multiple suction blocks 223 are brought closer together. During this process, the suction blocks 223 gradually contact and press the flame-retardant aluminum foil extending beyond the end face of the inner liner 6, causing the aluminum foil to gradually bend inward along the arc-shaped contour of the end face of the inner liner 6. When the suction block 223 moves to one side of the end face of the inner liner 6, the feeding moving component 21 again drives the feeding component 22 to move towards the end face of the inner liner 6, using the suction block 223 to tightly press the flame-retardant aluminum foil onto the arc-shaped end face of the inner liner 6. At this point, the suction block 223 can adaptively adjust its posture according to the curvature of the arc-shaped end face to ensure the pressing effect. After the flame-retardant aluminum foil is pressed tightly onto the end of the inner liner 6, the operator uses aluminum foil tape to fix the aluminum foil to the end face of the inner liner 6.

[0060] Reference Figure 5 , Figure 6 and Figure 10When the aluminum foil feeding mechanism 2 needs to feed the aluminum foil 7 from the aluminum foil support frame 5 to the end of the inner liner 6, the rotating component 23 drives the feeding component 22 mounted on it to rotate as a whole through the feeding moving component 21, until the suction block 223 in the feeding component 22 faces the aluminum foil 7 on the aluminum foil support frame 5. Then, the feeding drive motor 224 in the feeding component 22 works, adjusting the suction block 223 to a vertical position. Then, the feeding moving component 21 moves, driving the feeding component 22 to move closer to the aluminum foil support frame 5, until the suction block 223 adheres to the surface of the aluminum foil 7. At this time, the air pump draws air through the air pipe 2233, causing the suction block 223 to adhere to the aluminum foil 7. Then, the feeding moving component 21 drives the feeding component 22 to move away from the aluminum foil support frame 5. After moving into position, the rotating component 23 again drives the feeding component 22 to deflect through the feeding moving component 21, until the suction block 223 faces the end of the inner liner 6. Subsequently, the feeding moving assembly 21 drives the feeding assembly 22 to move closer to the end of the inner liner 6, transporting and pressing the aluminum foil sheet 7 adsorbed by the suction blocks 223 onto the end of the inner liner 6. Then, the operator uses aluminum foil tape to simply position the aluminum foil sheet 7 onto the pre-fixed flame-retardant aluminum foil at the end of the inner liner 6. After initial positioning, the feeding moving assembly 21 drives the feeding assembly 22 to retract slightly away from the end of the inner liner 6. Simultaneously, the feeding drive motor 224 operates, driving multiple suction blocks 223 to move away from each other until each suction block 223 moves to the outer edge area of ​​the adsorbed aluminum foil sheet 7. Finally, the feeding moving assembly 21 again drives the feeding assembly 22 to move closer to the inner liner 6, using the suction blocks 223 to press the edge portion of the aluminum foil sheet 7 onto the previously fixed flame-retardant aluminum foil.

[0061] Reference Figures 9-11The limiting component 8 is used to maintain the length direction of the suction block 223 perpendicular to the length direction of the second support rod 2222. This perpendicular state facilitates the stable adsorption of the aluminum foil sheet 7 by the suction block 223. When the suction block 223 is in contact with the arc surface of the end of the inner liner 6, the suction block 223 can adaptively deflect around the fourth rotation axis. During this deflection process, the suction block 223 pushes the slider 81 on the side of the second support rod 2222 that is close to the feeding drive screw 225, causing the slider 81 to slide along the second support rod 2222 towards the feeding drive motor 224 and compress the corresponding spring 82; at the same time, the spring 82 on the side of the second support rod 2222 away from the feeding drive screw 225 releases its stored energy, pushing the slider 81 on that side to slide along the second support rod 2222 towards the suction block 223. After the suction block 223 disengages from the end face of the inner liner 6, the force of the springs 82 on both sides pushes the corresponding sliders 81 to move, thereby causing the suction block 223 to rotate in the opposite direction around the fourth rotation axis, so that the length direction of the suction block 223 returns to a state perpendicular to the length direction of the second support rod 2222. The rubber cotton at the end of the suction block 223 not only provides cushioning and protection, avoiding scratches or indentations on the surface of the aluminum foil 7 during suction and pressing, but its soft texture can also better adapt to the curved contour of the end of the inner liner 6, increasing the contact area during bonding and improving the reliability and quality of bonding.

[0062] The implementation principle of the LNG vehicle-mounted bottle insulation layer winding forming device and method in this application is as follows: First, the inner liner 6 is driven to rotate by the rotary drive motor 11 on the inner liner rotating support frame 1, thereby automatically winding non-flame-retardant aluminum foil and flame-retardant aluminum foil around the circumferential side of the inner liner 6. During the winding process, the cutting component 13 cuts the aluminum foil after completing a specified number of turns. This process automates the winding of the aluminum foil around the circumferential side. For the attachment of the aluminum foil sheet 7 on the end face of the inner liner 6, this application achieves automated operation through the aluminum foil sheet feeding mechanism 2. After the aluminum foil is wound, the support frame moving component 4 moves the inner liner rotating support frame 1 away from the cutting component 13 to avoid interference between the aluminum foil sheet feeding mechanism 2 and the inner liner rotating support frame 1 during the feeding process. Subsequently, the aluminum foil sheet feeding mechanism 2 starts to work. The rotating component 23 drives the feeding moving component 21 and the feeding component 22 to rotate, so that the suction block 223 faces the aluminum foil sheet 7 on the aluminum foil sheet support frame 5. The feeding drive motor 224 in the feeding assembly 22 adjusts the suction block 223 to a vertical position. The feeding moving assembly 21 drives the feeding assembly 22 to move, causing the suction block 223 to adhere to the surface of the aluminum foil sheet 7. The air pump draws air through the air pipe 2233, and the suction block 223 adsorbs the aluminum foil sheet 7. Then, the feeding moving assembly 21 drives the feeding assembly 22 to move away from the aluminum foil sheet support frame 5. The rotating assembly 23 again drives the feeding moving assembly 21 and the feeding assembly 22 to deflect, so that the suction block 223 faces the end of the inner liner 6. The feeding moving assembly 21 drives the feeding assembly 22 to move closer to the end of the inner liner 6, transporting and pressing the aluminum foil sheet 7 against the end of the inner liner 6. The operator uses aluminum foil tape to simply position the aluminum foil sheet 7. Subsequently, the feeding drive motor 224 drives multiple suction blocks 223 to move away from each other, so that the suction blocks 223 move to the outside of the edge area of ​​the aluminum foil sheet 7. The feeding moving component 21 then drives the feeding component 22 to move closer to the inner liner 6, and uses the suction blocks 223 to press the edge part of the aluminum foil sheet 7 onto the previously fixed flame-retardant aluminum foil.

[0063] Compared with the prior art, this application achieves automatic feeding and attachment of aluminum foil sheets to the inner liner end face through the coordinated operation of components such as the aluminum foil feeding mechanism 2 and the support frame moving assembly 4, avoiding the problems of limited operating space and uneven attachment during manual attachment. The rotating assembly 23 provides horizontal angle adjustment, the feeding moving assembly 21 realizes positional movement, the feeding assembly 22 adsorbs and presses the aluminum foil sheet 7 through the suction block 223, and the bearing assembly 3 stably supports the inner liner 6. These components together improve the attachment efficiency and quality, and reduce the complexity and time consumption of manual operation.

[0064] 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.
