Description

Technical Field

[0001] The present application relates to the technical field of production and processing of type IV bottles, and in particular to an independent device for rotating and compensating pressure slip rings of type IV bottles during solidification. Background Art

[0002] China's automotive hydrogen storage bottle industry is accelerating its development, especially Type IV hydrogen storage bottles, which have become the "new favorite" of the fuel cell vehicle industry due to their excellent resistance to hydrogen embrittlement and corrosion, lighter weight, lower cost, higher quality hydrogen storage density and cycle life. The main production processes of Type IV bottles include liner molding, winding and curing, etc. The development of these processes has played a key role in improving the overall performance of hydrogen storage bottles and reducing costs. With the increasing popularity of hydrogen energy applications, higher requirements are placed on the performance of hydrogen storage bottles, especially in the winding and curing process in production, to ensure product consistency and reliability.

[0003] Type IV cylinders (Type IV hydrogen storage cylinders) need to be pressurized and inflated during the curing process, mainly because the temperature during curing will affect the change in the lining pressure. The change in pressure will cause damage to the lining or separation of the lining layer, transition layer and fiber winding layer, as well as the layered curing of the cylinder liner and fiber winding layer. These problems will directly affect the performance and quality of Type IV cylinders and ultimately lead to unqualified products. Therefore, while rotating and curing Type IV cylinders in the curing furnace, the internal pressure of the lining needs to be inflated and maintained in real time. Ensure that the lining of the cylinder is always in contact with the fiber winding layer during the curing process.

[0004] The curing furnaces currently available on the market are integrated solutions of high-temperature boxes and air supply devices. These devices usually use high-temperature boxes for thermal curing treatment, and are equipped with air supply devices to adjust the lining pressure, thereby avoiding problems such as lining damage or liner delamination. However, the problem with the above-mentioned curing furnaces is that the equipment procurement cost is high, and the work stations are limited. Only one or two gas cylinders can be processed at a time during curing, resulting in low production efficiency. In addition, the existing air supply device cannot effectively solve the problem of axis eccentricity caused by the manufacturing error of the liner and the tooling processing error during the rotation process, resulting in large transmission resistance and unstable air supply effect. Summary of the invention

[0005] In order to improve the flexibility and production efficiency of the air replenishment device during the curing process of Type IV bottles while reducing costs, and effectively solve the resistance problem caused by the eccentricity of the axis during the rotation of the transmission shaft, the present application provides an independent device for rotating pressure replenishing slip rings during the curing of Type IV bottles.

[0008] Optionally, the driving device includes an active roller, a driven roller and a power assembly, the axes of the active roller and the driven roller are arranged along the first direction and are located at the same height position, the active roller and the driven roller are connected to the air supply frame so as to be rotatable around their own axes, and the power assembly is drivingly connected to the active roller to drive the active roller to rotate around its own axis.

[0009] By adopting the above technical solution, the axes of the active roller and the driven roller are arranged in the same direction, and the winding rod of the four-type bottle is in contact with the active roller and the driven roller at the same time. When the active roller rotates around its own axis under the action of the power component, it can drive the winding rod to rotate together. The axes of the active roller and the driven roller are located at the same height position so that the two can maintain a relatively stable spacing and contact force during the rotation process, thereby avoiding vibration of the four-type bottle caused by position deviation or poor contact.

[0013] By adopting the above technical solution, the rotation of the adjustment knob can move along the extension direction of the clamping chute, and then the contact force between the clamping roller and the four-type bottle winding rod can be adjusted by compressing the elastic member. When the contact pressure needs to be increased, the adjustment knob is rotated forward, and the adjustment knob gradually approaches the clamping shaft in the clamping chute. At the same time, the elastic member is further compressed, generating a greater rebound force, pushing the clamping shaft to drive the clamping roller to fit more closely to the winding rod of the four-type bottle. On the contrary, the adjustment knob is rotated in the reverse direction, and the adjustment knob gradually moves away from the clamping shaft in the clamping chute, the elastic member relaxes, and the rebound force generated is reduced, thereby reducing the contact pressure. This design makes the adjustment of the clamping force simple and quick, and can change the rigid contact between the clamping roller and the winding rod into a flexible contact. On the one hand, it ensures the stability and effectiveness of the pressure replenishment process, and on the other hand, it can adapt to the axis eccentricity problem that occurs during the rotation of the winding rod.

The sliding rod is arranged along the first direction to provide a guide for the sliding of the skateboard.

DETAILED DESCRIPTION

[0027] The following is combined with Figure 1-8 This application is described in further detail.

[0028] The Type 4 bottle includes a bottle body and two winding rods at both ends of the bottle body. The bottle body includes an inner liner, lining material, transition layer, fiber winding layer, outer protective layer, and buffer layer from the inside to the outside. Since the radius of hydrogen atoms is small and hydrogen has strong permeability under high pressure, the lining material of the Type 4 bottle needs to have a good barrier function to prevent gas leakage. The production of Type 4 bottles can be roughly divided into two main links: inner liner molding and winding curing.

[0029] Among them, the winding methods in winding curing mainly include circumferential winding and spiral winding. Circumferential winding is winding along the circumferential direction of the container. The characteristics of circumferential winding are that winding can only be carried out on the barrel section and cannot be wound around the head. Adjacent yarn sheets are connected without overlapping, and the fiber winding angle is usually between 85° and 90°. Spiral winding is also called geodesic winding. The core mold rotates at a constant speed around its own axis, and the guide wire head reciprocates along the axis of the core mold at a specific speed. The winding is carried out on the barrel section and the head, and the winding angle is about 12°~70°. In order to ensure that the four-type bottle meets the pressure requirements of use after winding, the winding method generally selects a combination of circumferential winding and spiral winding. At the same time, a second tooth coupling and a quick-plug female head are left at one of the two winding rods. The quick-plug female head is connected to the inside of the bottle body, thereby laying the foundation for pressurizing and inflating the four-type bottle during the winding curing process.

[0030] The embodiment of the present application discloses an independent device for rotating and compensating the pressure of a type IV bottle during solidification by means of a sliding ring.

[0031] like Figure 1 As shown, the independent device of the rotary pressure-compensating slip ring for type IV bottles during solidification includes a frame, a driving device and an independent rotary pressure-compensating device, wherein the frame includes an air-compensating frame 1 and a support frame 2 relatively arranged along a first direction, and the support frame 2 is provided with a supporting assembly for supporting a winding rod 2202 of the type IV bottle 22; the driving device is arranged on the air-compensating frame 1, and is used to drive the type IV bottle 22 to rotate; the independent rotary pressure-compensating device is arranged on the air-compensating frame 1, and is used to replenish air into the rotating type IV bottle 22 through the winding rod 2202 of the type IV bottle 22, thereby achieving the effect of reducing equipment procurement costs and improving production efficiency.

[0032] like Figure 1 As shown, the frame includes an air-supplementing frame 1 and a support frame 2 which are arranged relatively along a first direction. The air-supplementing frame 1 is used to fix the driving device and the independent rotating pressure-supplementing device. The support frame 2 is provided with a support assembly, which includes two support rollers 3. The axes of the two support rollers 3 are both arranged along the first direction and are located at the same height. The two support rollers 3 are used to support the two winding rods 2202 of the four-type bottle 22 which are not provided with the second tooth-shaped coupling 2203 and one of the quick-connect female connectors, so as to assist the four-type bottle 22 in rotating.

[0033] like Figure 2 and Figure 3As shown, the driving device includes an active roller 4, a driven roller 5 and a power assembly, and the axes of the active roller 4 and the driven roller 5 are arranged along the first direction and are located at the same height. The active roller 4 and the driven roller 5 are both connected to the air supply frame 1 so as to rotate around their own axes, and the active roller 4 is coaxially arranged with one of the two supporting rollers 3, and the driven roller 5 is coaxially arranged with the other of the two supporting rollers 3. The shaft diameters of the active roller 4, the driven roller 5 and the two supporting rollers 3 are all equal. The power assembly is connected to the active roller 4 to drive the active roller 4 to rotate around its own axis, thereby achieving the effect of transmitting power.

[0034] like Figure 1 and Figure 2 As shown, the power assembly includes a motor 6, a first sprocket 7, a second sprocket 8 and a transmission chain (not shown in the figure), the motor 6 is arranged on the gas supply frame 1, the first sprocket 7 is arranged at the output end of the motor 6, the second sprocket 8 is arranged at one end of the active roller 4, and the first sprocket 7 and the second sprocket 8 are connected by the transmission chain. The axes of the active roller 4 and the driven roller 5 are arranged in the same direction, and the winding rod 2202 of the four-type bottle 22 is in contact with the active roller 4 and the driven roller 5 at the same time. When the motor 6 is started, the motor 6 drives the first sprocket 7 to rotate, and under the action of the transmission chain, the second sprocket 8 rotates with the first sprocket 7, so that the active roller 4 rotates around its own axis under the action of the power assembly, and at the same time, because the active roller 4 is in contact with the winding rod 2202, the active roller 4 can drive the winding rod 2202 to rotate together. The axes of the active roller 4 and the driven roller 5 are located at the same height position so that the two can maintain a relatively stable spacing and contact force during the rotation process, thereby avoiding the vibration of the four-type bottle 22 caused by position deviation or poor contact.

[0035] like Figure 2 and Figure 3 As shown, in order to promote close contact between the active roller 4 and the winding rod 2202, the driving device may further include a clamping assembly. The clamping assembly includes a clamping frame 9 and two clamping rollers 10. The axes of the clamping rollers 10 are arranged along the first direction and are connected to the clamping frame 9 so as to be rotatable around their own axes. The clamping frame 9 is hingedly connected to the air supply frame 1 at one end along the second direction perpendicular to the first direction, and a locking buckle 901 is provided at the other end. The air supply frame 1 is provided with a clamping ring 101 that matches the locking buckle 901. The clamping frame 9 has a working position and a standby position. When the clamping frame 9 is in the working position, the locking buckle 901 matches the clamping ring 101. The combination of the hinged connection and the locking buckle 901 enables the clamping frame 9 to switch freely between the working position and the standby position. When the clamping frame 9 is in the working position, the locking buckle 901 matches the clamping ring 101.

[0036] When the clamping frame 9 is in the working position, the two clamping rollers 10 are in synchronous contact with the winding rod 2202 of the four-type bottle 22, and apply a force toward the active roller 4 and the driven roller 5 to the winding rod 2202, which ensures that the winding rod 2202 can be firmly attached to the active roller 4 and the driven roller 5 during the curing process of the four-type bottle 22, thereby improving the stability and safety of the four-type bottle 22 during the rotation and pressure replenishment process. It prevents the four-type bottle 22 from deviating or falling off during the rotation process, thereby improving the accuracy of pressure replenishment and the curing quality of the product.

[0037] like Figure 2 and Figure 3 As shown, in order to change the rigid contact between the two pressing rollers 10 and the winding rod 2202 into a flexible contact, the pressing assembly may further include a pressing shaft 11 , an elastic member 12 and an adjusting knob 13 . The clamping roller 10 is coaxially connected to the clamping shaft 11 for rotation. The clamping frame 9 also includes two frame plates 902 arranged opposite to each other along the first direction. Two clamping grooves 903 are provided on the frame plates 902. The adjusting knob 13 passes through the clamping groove 903 along the extension direction of the clamping groove 903 and is threadedly connected to the frame plates 902. Adjustment holes for slidingly cooperating with the adjusting knob 13 are provided at both ends of the clamping shaft 11. The clamping shaft 11 is slidably connected to the adjusting knob 13 through the adjustment holes. A limit retaining ring 1301 is provided on the adjusting knob 13, and the limit retaining ring 1301 is located in the clamping groove 903. The elastic member 12 is sleeved on the adjusting knob 13. One end of the elastic member 12 abuts against the limit retaining ring 1301, and the other end abuts against the clamping shaft 11. In this embodiment, the elastic member 12 is a spring. In some other embodiments, the elastic member 12 can be a high temperature resistant tubular foam.

[0038] When the adjusting knob 13 is rotated, it can be connected by a thread, and the rotation around its own axis can be converted into movement along the extension direction of the pressing chute 903, and then the contact force between the pressing roller 10 and the winding rod 2202 of the four-type bottle 22 can be adjusted by compressing the elastic member 12. When the contact pressure needs to be increased, the adjusting knob 13 is rotated forward, and the adjusting knob 13 gradually approaches the pressing shaft 11 in the pressing chute 903. At the same time, the elastic member 12 is compressed by the limit ring 1301, generating a greater rebound force, pushing the pressing shaft 11 to drive the pressing roller 10 to fit the winding rod 2202 of the four-type bottle 22 more closely. On the contrary, the adjusting knob 13 is rotated in the reverse direction, and the adjusting knob 13 gradually moves away from the pressing shaft 11 in the pressing chute 903. The limit ring 1301 also moves away from the pressing shaft 11, and the elastic member 12 relaxes, and the rebound force generated is reduced, thereby reducing the contact pressure. This design makes the adjustment of the clamping force simple and quick, and can change the rigid contact between the clamping roller 10 and the winding rod 2202 into flexible contact. On the one hand, it ensures the stability and effectiveness of the pressure compensation process, and on the other hand, it can adapt to the axis eccentricity problem that occurs during the rotation of the winding rod 2202.

[0039] like Figure 4 As shown, the independent rotary pressure-compensating device includes a propulsion mechanism and a pressure-compensating slip ring mechanism 20, the propulsion mechanism is fixedly connected to the clamping frame 9, the propulsion mechanism is used to drive the pressure-compensating slip ring mechanism 20 to reciprocate along the first direction, and the pressure-compensating slip ring mechanism 20 is used to cooperate with the winding rod 2202 to compress and inflate the four-type bottle 22. The propulsion mechanism is fixedly connected to the clamping frame 9, and the pressure-compensating slip ring mechanism 20 is arranged at the output end of the propulsion mechanism.

[0040] The propulsion mechanism can ensure that during the rotation of the type-four bottle 22, the pressure-compensating slip ring mechanism 20 can remain closely connected with the winding rod 2202 of the type-four bottle 22, and the pressure-compensating slip ring mechanism 20 ensures that the gas can be continuously and evenly input into the interior of the type-four bottle 22 during the rotation of the type-four bottle 22, effectively avoiding problems such as lining damage, liner delamination, or separation of the plastic lining and the carbon fiber reinforcement layer, and significantly improving the performance and quality stability of the type-four bottle 22.

[0041] like Figure 4 As shown, specifically, the propulsion mechanism includes a mounting plate 14, a slide rod 15, a slide plate 16 and a propulsion assembly. The slide rod 15 is arranged along a first direction. The mounting plate 14 is fixedly connected to the clamping frame 9 through the slide rod 15. The slide plate 16 is slidably connected to the slide rod 15. The propulsion assembly is fixedly connected to the mounting plate 14. The driving end of the propulsion assembly is drivingly connected to the slide plate 16 to drive the slide plate 16 to reciprocate along the extension direction of the slide rod 15. The pressure compensation slip ring mechanism 20 is fixedly connected to the slide plate 16.

[0042] The mounting plate 14 serves as a basis and is connected to the pressing frame 9 through the slide bar 15, thereby ensuring the stability of the entire propulsion mechanism during operation. The slide bar 15 is arranged along a first direction to provide a guide for the sliding of the slide plate 16. The slide plate 16, as a movable component, is slidably connected to the slide bar 15, so that the slide plate 16 can reciprocate along the extension direction of the slide bar 15 under the drive of the propulsion assembly. The propulsion assembly, as a power source, is fixedly connected to the mounting plate 14, thereby ensuring the stable transmission of the driving force. When the propulsion assembly is started, its driving end will apply a force to the slide plate 16, driving the slide plate 16 to move along the slide bar 15 toward the pressing frame 9; when the slide plate 16 needs to return, the propulsion assembly will change the direction of the driving force to make the slide plate 16 move in the opposite direction along the slide bar 15.

[0043] Among them, Figure 4As shown, in this embodiment, the propulsion assembly may include a hand wheel 17 and a propulsion rod 18, the propulsion rod 18 is parallel to the slide bar 15 and is threadedly connected to the mounting plate 14, one end of the propulsion rod 18 is rotatably connected to the slide plate 16, and the other end is fixedly connected to the hand wheel 17. In order to increase the overall stability, a locking handle 19 for locking the rotation of the propulsion rod 18 may also be provided at the mounting plate 14. By rotating the hand wheel 17, since the hand wheel 17 is fixedly connected to the other end of the propulsion rod 18, the propulsion rod 18 can rotate with the hand wheel 17. The propulsion rod 18 is threadedly connected to the mounting plate 14, so that the propulsion rod 18 can move linearly along its own axis when rotating. With the linear motion of the propulsion rod 18, the part of one end of the propulsion rod 18 that is rotatably connected to the slide plate 16 will drive the slide plate 16 to move accordingly, thereby realizing the conversion from rotational motion to linear motion. After the adjustment is completed, the propulsion rod 18 can be locked in the desired position by the locking handle 19 to prevent it from being offset due to external force or vibration, thereby ensuring the stability and reliability of the device. The structure of the locking handle 19 is a conventional technical means in the art, and this application will not elaborate on it here. Figure 5 As shown, in some other embodiments, the propulsion assembly may further include a cylinder 23, the cylinder 23 body is fixedly connected to the mounting plate 14, and the movable end of the cylinder 23 is fixedly connected to the slide 16, so that the slide 16 is driven to move by the cylinder.

[0044] like Figure 6 and Figure 7As shown, the pressure-compensating slip ring mechanism 20 includes a slip ring housing 2001, a connecting sleeve 2002, a ventilation hose 2003 and a rotating shaft 2004. The connecting sleeve 2002 is connected to the rotating shaft 2004, and the connecting sleeve 2002 can rotate with the rotating shaft 2004. A first tooth-shaped coupling 2005 is provided at one end of the connecting sleeve 2002 away from the rotating shaft 2004. A quick-connect male connector 2006 is provided at the center of the first tooth-shaped coupling 2005. A first air interface 20061 is provided at one end of the quick-connect male connector 2006 close to the rotating shaft 2004. A first air joint 2009 is provided at the first air interface 20061. The slip ring housing 2001 is provided with an air inlet 20012. A ventilation ring 20011 is provided at the inner wall, the air inlet 20012 is connected to the ventilation ring 20011, sealing rings 2007 are provided on both sides of the ventilation ring 20011, a second air interface 20041 is provided at one end of the rotating shaft 2004 close to the connecting sleeve 2002, a second air joint 20010 is provided at the second air interface 20041, a rotating air interface 20042 connected to the second air interface 20041 is provided at one side of the rotating shaft 2004, two ends of the ventilation hose 2003 are respectively connected to the first air joint 2009 and the second air joint 20010, the slip ring housing 2001 is sleeved outside the rotating shaft 2004, and the rotating air interface 20042 is connected to the ventilation ring 20011. In order to ensure that the slip ring housing 2001 and the rotating shaft 2004 can rotate smoothly, a bearing 2008 can be provided between the slip ring housing 2001 and the rotating shaft 2004.

[0045] When the pressure-compensating slip ring mechanism 20 is working, the gas source enters from the air inlet 20012 on the slip ring housing 2001, passes through the vent ring 20011 and reaches the gas path assembly through the rotating gas interface 20042 on the rotating shaft 2004, and finally passes to the inside of the four-type bottle 22 through the quick-plug male connector 2006 and the quick-plug female connector provided on the winding rod 2202 to achieve pressure-compensating inflation. The inner wall of the slip ring housing 2001 is provided with a sealing ring 2007 to ensure sealing and prevent gas leakage. The cooperation of the first tooth-shaped coupling 2205 and the second tooth-shaped coupling 2203 ensures that the rotating shaft 2004 can rotate smoothly with the winding rod 2202. During the rotation of the rotating shaft 2004, the rotating air interface 20042 rotates with the rotating shaft 2004. Since the inner wall of the slip ring housing 2001 is provided with a ventilation ring 20011, the rotating air interface 20042 always maintains communication with the ventilation ring 20011 during the rotation of the rotating shaft 2004, ensuring the smoothness of the air path and realizing continuous pressurization of the four-type bottle 22 during the rotational curing process, avoiding damage to the lining or separation of the lining from the fiber layer during the curing process, thereby improving the curing quality and production efficiency of the four-type bottle 22.

[0046] like Figure 7 and Figure 8As shown, in order to compensate for the eccentric rotation that may be generated during the rotation of the four-type bottle 22, the compensating slip ring mechanism 20 may further include a compensator 21, which is arranged between the connecting sleeve 2002 and the rotating shaft 2004. The compensator 21 includes a cross slider 2101, an output shaft of the compensator 21, and an input shaft of the compensator 21. A transverse slide rail 21011 is provided at one end of the cross slider 2101, and a longitudinal slide rail 21012 perpendicular to the transverse slide rail 21011 is provided at the other end. The output shaft of the compensator 21 is slidably connected to the cross slider 2101 through the transverse slide rail 21011, and the input shaft of the compensator 21 is slidably connected to the cross slider 2101 through the longitudinal slide rail 21012. Limiting grooves 21013 are provided on both sides of the transverse slide rail 21011 and the longitudinal slide rail 21012. Limiting screw holes 2104 for cooperating with limiting screws are provided on the output shaft of the compensator 21 and the input shaft of the compensator 21. The limiting screws pass through the limiting screw holes 2104 and are slidably connected with the limiting grooves 21013.

[0047] The compensator 21 is arranged between the connecting sleeve 2002 and the rotating shaft 2004. Through the sliding connection of the cross slider 2101 and its transverse slide rail 21011 and the longitudinal slide rail 21012, the eccentricity of the axis line is compensated during the rotation process, thereby reducing the resistance caused by the eccentricity of the axis line due to the manufacturing error of the inner liner and the tooling processing error during the transmission process, ensuring the stability and reliability of the pressure compensation slip ring mechanism 20 during the rotation process, and improving the transmission efficiency. The design of the limiting slide groove 21013 and the limiting screw enables the output shaft of the compensator 21 and the input shaft of the compensator 21 to slide stably on the transverse slide rail 21011 and the longitudinal slide rail 21012 to avoid derailment.

[0048] The implementation principle of the independent device for rotating pressure-compensating slip ring of type IV bottle during curing in the embodiment of the present application is as follows: the type IV bottle 22 to be cured is placed on the frame, the winding rod 2202 is fixed on the active roller 4 by the clamping assembly in the driving device, and then the pressure-compensating slip ring mechanism 20 is pushed by the propulsion mechanism to move the first tooth-shaped coupling 2005 and the second tooth-shaped coupling 2203 on the winding rod 2202, and the quick-plug male connector 2006 is also connected to the quick-plug female connector in the winding rod 2202. The air source enters from the air inlet 20012 on the slip ring housing 2001, passes through the vent ring 20011 and reaches the air path assembly through the rotating air interface 20042 on the rotating shaft 2004, and is finally transmitted to the inside of the type IV bottle 22 through the quick-plug male connector 2006 and the quick-plug female connector provided on the winding rod 2202. When the active roller 4 rotates, the winding rod 2202 is driven to rotate, and the winding rod 2202 drives the first tooth-shaped coupling 2005 to rotate through the second tooth-shaped coupling 2203, thereby driving the rotating shaft 2004 to rotate, so that the four-type bottle 22 can be pressed while rotating. In this transmission process, the motion is transmitted as the shaft connection rotation, and there are many connected follower parts, which requires high coaxiality for installation. At the same time, due to the manufacturing error of the inner liner of the bottle body 2201 of the four-type bottle 22 and the tooling processing error, the axis center line of the shaft is relatively eccentric during the transmission process. The compensator 21 solves the eccentricity problem between the shafts, can compensate for the eccentricity of the axis in the rotational motion in real time, and also reduces the transmission resistance.

[0049] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
