Detailed implementation manners

[0031] The following uses specific specific examples to illustrate the implementation manners of the present utility model. Those skilled in the art can easily understand other advantages and effects of the present utility model from the content disclosed in this specification. The present utility model can also be implemented or applied through other different specific implementation manners. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present utility model. It should be noted that, without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0032] It should be noted that the drawings provided in the following embodiments only illustrate the basic concept of the present utility model in a schematic manner. Therefore, only the components related to the present utility model are shown in the drawings, rather than being drawn according to the number, shape, and size of the components in actual implementation. The type, quantity, and ratio of each component in actual implementation can be arbitrarily changed, and the component layout type may also be more complex.

[0033] As Figure 3 , 4 shown in Figure 5, the present utility model provides a semi-rolling device for an air spring airbag, which is applied to an air spring airbag. The air spring airbag includes an airbag body 1, and both ends of the airbag body 1 are through holes and are cylindrical. It is usually used in the suspension systems in the industrial and automotive fields. They can adjust the suspension height and hardness by inflating and deflating. The device includes a frame 10, a base 20, a first sealing plate 30, a second sealing plate 40, and a pressing device 50. The frame 10 is the framework of the whole device, and the frame 10 is of a C-shaped structure as a whole. This structure is to provide sufficient support and stability to maintain the structural integrity of the device when handling and compressing the airbag.

[0034] The base 20 is arranged on the frame 10. The base 20 provides additional support and stability to ensure that the whole device remains firm and balanced during operation. The base 20 is installed on the frame 10 through bolts or other fixing devices to ensure that it is firmly connected together.

[0035] The first sealing plate 30 is used to seal the first end of the airbag body 1. The first end of the airbag body 1 is the upper end, and the first sealing plate 30 is sealed in cooperation with the upper bead profile of the airbag.

[0036] The second sealing plate 40 is used to seal the second end of the airbag body 1. The second end of the airbag body 1 is the lower end. The second sealing plate 40 is arranged on the base 20, and the second sealing plate 40 is sealed in cooperation with the lower bead profile of the airbag. Among them, the first sealing plate 30 and the second sealing plate 40 are arranged at intervals to form a space for accommodating the airbag body 1.

[0037] The pressing device 50 is arranged on the frame 10. The pressing device 50 is used to drive the first sealing plate 30 to approach the second sealing plate 40 to compress the airbag body 1.

[0038] During use, first place the airbag body 1 between the first sealing plate 30 and the second sealing plate 40. These two sealing plates are used to seal the two ends of the airbag to ensure that gas does not leak.

[0039] Then, the pressing device 50 starts to work, driving the first sealing plate 30 to move towards the second sealing plate 40. During this process, the force applied by the pressing device 50 will gradually compress the airbag body 1.

[0040] When there is a certain pressure inside the airbag, the airbag will automatically start to roll up, changing from the natural state in Figure 1 to the semi-rolled state shown in Figure 2 . This rolling-up state is achieved by compressing the airbag, thereby reducing the volume of the airbag.

[0041] Compressing the airbag into a semi-rolled state can significantly reduce its volume, which is very important during storage and transportation, saving space and costs.

[0042] At the same time, the compressed airbag still maintains a certain internal pressure and structural strength, which ensures that it can quickly return to its original shape and function when needed.

[0043] Such as Figure 3 、 4 As shown in 5, an exhaust valve 31 communicating both sides of the plate surface is provided on the first sealing plate 30. The exhaust valve 31 can control whether to exhaust air during the semi-rolling process of the air spring inflation, ensuring the smooth semi-rolling of the workpiece. When the internal air pressure of the air spring is too high or too low, the exhaust valve 31 can be used to control the exhaust volume. It is only used as a backup when air exhaust is required in the air spring inflation state, and it does not need to be connected to other air pipe components, etc. During the semi-rolling process of the air spring inflation, the main function of the exhaust valve 31 is to control the discharge of gas to ensure that the workpiece (i.e., the airbag) can be smoothly semi-rolled. If the internal air pressure of the air spring is too high or the air pressure needs to be adjusted, the exhaust valve 31 can be used to control the exhaust volume. In this way, the internal pressure of the airbag can be adjusted to ensure the required state during the semi-rolling process.

[0044] Such as Figure 3 、 4 As shown in 5, a flow rate regulating valve 32 communicating both sides of the plate surface is provided on the first sealing plate 30. It plays a role in regulating the flow rate of compressed air. When the device tooling is inflated, the gas flow rate can be adjusted, and it needs to be used in cooperation with the air pipe, manual valve, and pressure gauge two-piece. A first manual valve 60 connected to the flow rate regulating valve 32 is provided on the frame 10. The first manual valve 60 is connected to the flow rate regulating valve 32 using an air pipe, which can control the inflation and stop of the air, and is used in cooperation with the pressure gauge two-piece. During use, the operator can control the gas flow through the first manual valve 60 to adjust the inflation speed and pressure. The main task of the flow rate regulating valve 32 is to ensure a stable inflation process at the set gas flow rate. The pressure gauge two-piece provides necessary air pressure monitoring to ensure that the internal pressure of the airbag is within a safe range during the inflation process. This design not only improves the accuracy and control ability of the device but also simplifies the operation process and maintenance requirements. By precisely controlling the inflation speed and pressure, the stability and reliability of the airbag during the semi-rolling process can be ensured, improving work efficiency and quality assurance.

[0045] Such as Figure 3 、 4, as shown in FIGS. 5, the pressing device 50 is a cylinder or a hydraulic cylinder. Preferably, it is a cylinder. The cylinder is associated with the second manual valve 70 and is connected to each other by an air pipe and used in conjunction with a two-piece air pressure gauge. The switching process can ensure the rising and falling of the cylinder. The switching process of the cylinder refers to the rising and falling actions of the cylinder during the pressing operation. By reasonably controlling the operation of the second manual valve 70, the movement of the cylinder can be precisely controlled to ensure that the cylinder can rise and fall according to the set requirements during the pressing process.

[0046] As Figure 3 , 4 , as shown in FIGS. 5, the first sealing plate 30 is indirectly threaded to the push rod of the cylinder. There is a threaded portion on the push rod, and there are matching threaded holes on the first sealing plate 30. Through this threaded connection, the first sealing plate 30 can be fixed to the push rod so that it can move along with the movement of the push rod.

[0047] As Figure 3 , 4 , as shown in FIGS. 5, the base 20 includes a guide sleeve 21, a support plate 22, and a screw 23.

[0048] The guide sleeve 21 is provided on the frame 10. Its main function is to reduce the wear of the device and ensure the coaxiality of each component, which is crucial for the stable operation of the mechanical system. In addition, the guide sleeve 21 can also facilitate the replacement of accessories in the later stage because they are in contact with relatively large wear and are easy to replace.

[0049] The support plate 22 is provided at one end of the guide sleeve 21 close to the airbag body 1 for supporting the second sealing plate 40. The outer diameter of the support plate 22 is larger than the outer diameter of the airbag body 1 when it is inflated by itself. Its main function is to support the second sealing plate 40, which can ensure that the sealing plate is stably positioned and operates during the operation. The outer diameter of the support plate 22 is larger than the outer diameter of the airbag body 1 when it is inflated, which is to ensure that the support plate 22 can still firmly support the sealing plate when the airbag is inflated.

[0050] The screw 23 is used to insert into the guide sleeve 21 and pass through the support plate 22 and be threadedly connected to the second sealing plate 40. The screw 23 is a component that is inserted through the support plate 22 after being inserted into the guide sleeve 21 and then threadedly connected to the second sealing plate 40. This connection method is usually used to ensure the safe and reliable connection between the second sealing plate 40 and other components of the base 20. The function of the screw 23 is to provide sufficient fixing force to ensure that the sealing plate will not loosen or shift during the operation.

[0051] As Figure 3 , 4, as shown in Figures 5, the screw rod 23 and the airbag body 1 are arranged coaxially with the cylinder. The coaxial arrangement can ensure that the piston of the cylinder or hydraulic cylinder applies pressure evenly along the entire axis when compressing the airbag. This helps to avoid uneven pressure caused by skewing or misalignment, thereby reducing the stress concentration problem of the airbag body 1 during inflation and deflation. The coaxial arrangement helps to maintain the stability and accuracy of the system. When compressing the airbag, this arrangement can reduce the offset or distortion of mechanical components, ensuring that the airbag can be compressed or released as designed.

[0052] As Figure 3 , 4 , as shown in Figures 5, the screw rod 23 includes a threaded section near the second sealing plate 40 and a smooth rod section away from the second sealing plate 40. The diameter of the threaded section is greater than the inner diameter of the guide sleeve 21, and the diameter of the smooth rod section is less than the inner diameter of the guide sleeve 21. This can ensure that the screw rod 23 will not fall down when placed into the guide sleeve 21.

[0053] As Figure 3 , 4 , as shown in Figures 5, a plurality of positioning holes 24 are evenly spaced along the length direction of the smooth rod section. The positioning holes 24 are detachably connected to the frame 10 through positioning pins 25. After adjusting the natural height of the air spring appropriately, the positioning pins 25 can be inserted into the positioning holes 24 to achieve height adjustment and positioning. The function of the positioning holes 24 is to provide multiple fixing points so that the smooth rod section can be connected to the frame 10 through the positioning pins 25. The positioning pins 25 can be inserted into the corresponding holes on the frame 10 through these holes, thereby ensuring the precise positioning and fixation of the smooth rod section at a specific position. The positioning holes 24 on the smooth rod section allow height adjustment to be achieved by inserting the positioning pins 25. For example, when adjusting the natural height of the air spring, the appropriate position of the positioning holes 24 can be selected, and then the smooth rod section can be fixed by inserting the positioning pins 25 to achieve the required height adjustment. This design makes height adjustment simple and precise.

[0054] As Figure 3 , 4As shown in FIGS. 5, a support plate 51 is provided on the pressing device 50. A plurality of limiting holes 52 are formed in the support plate 51 and are arranged at uniform intervals along the pressing direction, where the pressing direction refers to the up-and-down direction. The limiting holes 52 are detachably connected to the machine frame 10 through limiting pins 53. In this way, the stroke height can be adjusted. By selecting different limiting holes 52 and inserting the corresponding limiting pins 53, the stroke height of the pressing device 50 can be adjusted. This provides a detachable connection method for the design of the limiting pins 53 and limiting holes 52 for different workpieces or products, making it very convenient to adjust the stroke height. The operator can easily insert or remove the limiting pins 53 for necessary stroke adjustment or maintenance work, and then reinstall and fix them. The pressing requirements provide flexibility and adjustability, enabling the operator to quickly adjust and set according to actual needs.

[0055] In summary, the present utility model provides an air spring airbag semi-rolling device. The device in the above solution can compress the airbag into a semi-rolled structure. After the airbag is compressed into a semi-rolled structure, its volume is significantly reduced. In this way, the space required for storage and transportation is greatly reduced, and the costs and resources of warehousing and transportation can be saved. Since the semi-rolled airbag occupies less packaging materials and transportation containers, the overall packaging and logistics costs will be reduced. This is particularly important for large-scale production and cross-regional or international transportation. During the production, packaging, and distribution processes, handling the semi-rolled airbag may be more efficient and convenient. This helps to reduce the use of human resources, while reducing the risk of operation complexity and errors. Reducing the use of packaging materials and the risk of damage to the airbag during transportation helps to reduce the impact on the environment. The semi-rolled structure design improves the safety of the airbag, reducing the possibility of leakage or damage, thus ensuring the quality and reliability of the product.
