Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] In order to solve the problem of difficulty in installing the capsule of the air spring drum in the prior art, the present invention provides an air spring drum and an air spring drum production system.

[0025] like Figure 1 and Figure 2 As shown, the air spring drum production system includes an air spring drum, and the air spring drum includes a main shaft 10, a locking ring assembly 20, a driving assembly 30, a turn-up assembly 40 and a turn-up capsule 50, wherein at least a portion of the locking ring assembly 20 is movably arranged on the main shaft 10, the locking ring assembly 20 has a locking ring groove 222, and the portion of the locking ring assembly 20 having the locking ring groove 222 can move in the direction in which the diameter of the main shaft 10 becomes larger to lock with the steel ring; at least a portion of the driving assembly 30 is movably arranged on the main shaft 10 and can move along the axial direction of the main shaft 10, and the driving assembly 30 is drivingly connected to the locking ring assembly 20; the turn-up assembly 40 is arranged on a side of the locking ring assembly 20 close to the end of the main shaft 10, the turn-up assembly 40 is detachably mounted on the main shaft 10, and at least a portion of the turn-up assembly 40 is mounted on the outer peripheral side of the driving assembly 30; the turn-up capsule 50 is detachably connected to the turn-up assembly 40, and one end of the turn-up capsule 50 is mounted on the locking ring assembly 20.

[0026] During the installation process of the turn-up capsule 50 in the present invention, the turn-up capsule 50 is first connected to the turn-up component 40, and then the turn-up capsule 50 and the turn-up component 40 are sleeved on the main shaft 10 from one axial end of the main shaft 10. During the disassembly process of the turn-up capsule 50, the turn-up capsule 50 and the turn-up component 40 are first removed from one axial end of the main shaft 10, and then the turn-up capsule 50 and the turn-up component 40 are disassembled, which makes the installation and disassembly of the turn-up capsule 50 easier, and will not damage the structure of the turn-up capsule 50, thereby increasing the service life of the turn-up capsule 50. One person can achieve quick installation and disassembly, saving labor costs and improving work efficiency.

[0027] like Figure 2As shown, the turn-up assembly 40 includes an air guide ring 41, a pressure plate 42 and a capsule support tube 43, wherein the air guide ring 41 is located on the outer peripheral side of the main shaft 10, at least a part of the turn-up capsule 50 is located on the outer peripheral side of the air guide ring 41, and the air guide ring 41 can inflate the interior of the turn-up capsule 50; the pressure plate 42 is located on the side of the air guide ring 41 close to the locking ring groove 222 in the axial direction of the main shaft 10, and the first fixing portion 51 of the turn-up capsule 50 is located between the pressure plate 42 and the air guide ring 41; the capsule support tube 43 is arranged on the side of the air guide ring 41 away from the pressure plate 42, and the second fixing portion 52 of the turn-up capsule 50 is located between the capsule support tube 43 and the air guide ring 41. In this way, the air guide ring 41 can directly inflate the interior of the turn-up capsule 50 to ensure good sealing inside the turn-up capsule 50, solving the problem in the prior art that the air nozzle of the capsule needs to be aligned with the air vent of the support plate, which increases the difficulty of installing the capsule. In addition, during the process of installing the capsule to the support plate, the air nozzle of the capsule is easy to fall off, resulting in poor sealing.

[0028] It should be noted that, in the present application, the gas guide ring 41 is provided with a plurality of evenly distributed outlet holes along its circumference, and the plurality of outlet holes are all located in the inverted capsule 50 and communicated with the interior of the inverted capsule 50. In this way, the plurality of outlet holes evenly fill the gas into the inverted capsule 50.

[0029] like Figure 2 As shown, the turn-up assembly 40 further includes at least one fixing member 44, which passes through the capsule support tube 43, the second fixing portion 52, the air guide ring 41, the first fixing portion 51 in sequence and is connected to the pressing plate 42. In this way, after the fixing member 44 fixes the air guide ring 41, the pressing plate 42, the capsule support tube 43, and the turn-up capsule 50 as a whole, the whole is installed at one axial end of the main shaft 10, ensuring that the installation and removal of the turn-up capsule 50 are easier and the turn-up capsule 50 will not be damaged.

[0030] Preferably, the fixing member 44 is a screw.

[0031] like Figure 1 and 2 As shown, the turn-up assembly 40 further includes an inflatable member 45, at least a portion of which extends from one end of the capsule support tube 43 away from the air guide ring 41 into the capsule support tube 43 and communicates with the air guide ring 41. In this way, the inflatable member 45 fills gas into the inside of the turn-up capsule 50 through the air guide ring 41, propping up the turn-up capsule 50 to achieve rubber material turn-up.

[0032] like Figure 2As shown, the air spring drum further includes a connecting sleeve 60, which is sleeved on the main shaft 10, and the turn-up assembly 40 is connected to the main shaft 10 through the connecting sleeve 60. In this way, when the air guide ring 41, the pressure plate 42, the capsule support tube 43, and the turn-up capsule 50 are fixed as a whole through the fixing member 44, the whole is connected to the connecting sleeve 60, which facilitates the installation and disassembly of the whole.

[0033] Preferably, one end of the connecting sleeve 60 is fixedly connected to the main shaft 10 and the drum body respectively by bolts, and the other end of the connecting sleeve 60 is detachably connected to the air guide ring 41 of the turn-up assembly 40 by bolts.

[0034] like Figure 2 As shown, the locking ring assembly 20 includes a connecting rod mechanism 21 and a flip support mechanism 22, wherein one end of the connecting rod mechanism 21 is connected to the driving assembly 30 and can move with the driving assembly 30. When the connecting rod mechanism 21 moves with the driving assembly 30, the angle between the connecting rod mechanism 21 and the main shaft 10 changes; the other end of the connecting rod mechanism 21 is connected to the flip support mechanism 22, and the end of the flip support mechanism 22 away from the connecting rod mechanism 21 is connected to the drum body and can rotate relative to the drum body. In this way, when the driving assembly 30 drives the connecting rod mechanism 21 to rotate, the angle between the connecting rod mechanism 21 and the main shaft 10 gradually increases or decreases, and the connecting rod mechanism 21 drives the flip support mechanism 22 to flip around the end connected to the drum body to achieve locking of the steel ring.

[0035] like Figure 2 As shown, the driving assembly 30 includes a sliding sleeve 31 and a connecting block 32, wherein the sliding sleeve 31 is sleeved on the main shaft 10 and can slide along the axial direction of the main shaft 10; the two ends of the connecting block 32 are respectively connected to the connecting rod mechanism 21 and the sliding sleeve 31. In this way, when it is necessary to lock the steel ring, the sliding sleeve 31 slides toward the drum body along the axial direction of the main shaft 10 to drive the connecting block 32 to slide toward the drum body along the axial direction of the main shaft 10, and the connecting rod mechanism 21 connected to the connecting block 32 rotates as the connecting block 32 slides, so that the angle between the connecting rod mechanism 21 and the main shaft 10 gradually increases, and the flip support mechanism 22 flips in the direction away from the main shaft 10 to lock with the steel ring; when the tire needs to be removed after the turn-up is completed, the sliding sleeve 31 slides in the direction away from the drum body to drive the connecting block 32 to slide away from the drum body, and the connecting rod mechanism 21 connected to the connecting block 32 rotates as the connecting block 32 slides, so that the angle between the connecting rod mechanism 21 and the main shaft 10 gradually decreases, and the flip support mechanism 22 flips in the direction close to the main shaft 10 until the flip support mechanism 22 is parallel to the axial direction of the main shaft 10, and the tire is removed.

[0036] like Figure 2As shown, the connecting rod mechanism 21 includes a plurality of connecting rods 211, and the flip support mechanism 22 includes a plurality of flip support blocks 221. The plurality of connecting rods 211 correspond to the plurality of flip support blocks 221 one by one, and different connecting rods 211 are respectively connected to the corresponding flip support blocks 221. In this way, the plurality of connecting rods 211 and the plurality of flip support blocks 221 drive the rubber material on the outer peripheral side of the reverse capsule 50 to move in the direction in which the diameter of the main shaft 10 becomes larger, so as to be locked with the steel ring.

[0037] Preferably, the plurality of connecting rods 211 and the plurality of flip support blocks 221 are evenly spaced and arranged along the circumference of the main shaft 10 to ensure that the inverted capsule 50 is subjected to balanced force in the circumferential direction.

[0038] like Figure 2 As shown, the other end of the flip support mechanism 22 close to the turn-up assembly 40 has a locking ring groove 222, and in the axial direction of the main shaft 10, the position where the connecting rod mechanism 21 is connected to the flip support mechanism 22 is located on the side of the locking ring groove 22 away from the turn-up assembly 40. In this way, the flip support mechanism 22 flips along the end connected to the drum body to ensure that the movement distance of the other end of the flip support mechanism 22 having the locking ring groove 222 is as large as possible, so as to improve work efficiency.

[0039] It should be noted that, in this application, the steps of using the air spring drum include:

[0040] 1) In the initial state, the extension direction of the flip support mechanism 22 is parallel to the axial direction of the main shaft 10;

[0041] 2) Applying rubber to the outer surface of the air spring drum;

[0042] 3) After the material pasting is completed, the connecting rod mechanism 21 drives the flip support mechanism 22 to flip in a direction away from the main shaft 10, so that the angle between the flip support mechanism 22 and the main shaft 10 gradually increases to support and lock the steel ring;

[0043] 4) The inflatable member 45 inflates the reverse capsule 50 through the air guide ring 41 to complete the reverse packaging;

[0044] 5) The connecting rod mechanism 21 drives the flipping support mechanism 22 to flip in the direction close to the main shaft 10, so that the angle between the flipping support mechanism 22 and the main shaft 10 gradually decreases until the angle is zero, and the carcass is unloaded.

[0045] From the above description, it can be seen that the above-mentioned embodiments of the present invention achieve the following technical effects: during the installation process of the turn-up capsule 50 in the present invention, the turn-up capsule 50 is first connected to the turn-up component 40, and then the turn-up capsule 50 and the turn-up component 40 are sleeved on the main shaft 10 from one axial end of the main shaft 10; during the disassembly process of the turn-up capsule 50, the turn-up capsule 50 and the turn-up component 40 are first removed from one axial end of the main shaft 10 together with the turn-up component 40, and then the turn-up capsule 50 and the turn-up component 40 are disassembled, which makes the installation and disassembly of the turn-up capsule 50 easier, and will not damage the structure of the turn-up capsule 50, thereby increasing the service life of the turn-up capsule 50, and one person can achieve quick installation and disassembly, saving labor costs and improving work efficiency.
