Description

Technical Field

[0001] This invention relates to the field of tire equipment technology, and more specifically, to an air spring drum and an air spring drum production system. Background Technology

[0002] In existing technology, the capsule-type V-type air spring drum is the core component of an air spring drum forming machine. Its working process is as follows: the air spring drum is in a retracted state for rubber application and rolling; after rolling, the steel ring is locked; and finally, the drum is reversed and the tire is removed. Existing air spring drums typically include a main shaft, a motion mechanism, a support plate, and a capsule. The motion mechanism is mounted on the main shaft, and the support plate is connected to the outer periphery of the motion mechanism away from the main shaft. The capsule is mounted on the outer periphery of the motion mechanism. After the rubber application is completed, at least a part of the motion mechanism can move in the direction of increasing main shaft diameter to lift the support plate and lock it with the steel ring. After the steel ring is locked, the capsule is inflated for reverse wrapping. After reverse wrapping is completed, the support plate falls back to remove the tire.

[0003] However, in the existing technology, the capsules need to be expanded before being fitted onto the support plate. Capsule installation is difficult and usually requires multiple people, which wastes labor costs. In addition, the capsules are easily damaged during the installation process, which shortens the capsule's lifespan and reduces production efficiency.

[0004] Therefore, there is a problem with the installation of the capsule in the air spring drum in the existing technology. Summary of the Invention

[0008] Furthermore, the reverse packaging assembly also includes at least one fixing member, which passes through the capsule support cylinder, the second fixing part, the air guide ring, and the first fixing part in sequence and is connected to the pressure plate.

[0009] Furthermore, the reverse packaging assembly also includes an inflation component, at least a portion of which extends into the capsule support cylinder from the end of the capsule support cylinder away from the air guide ring and communicates with the air guide ring.

[0010] Furthermore, the air spring drum also includes a connecting sleeve, which is fitted onto the main shaft, and the reverse wrapping assembly is connected to the main shaft through the connecting sleeve.

[0011] Furthermore, the locking ring assembly includes a linkage mechanism and a flipping support mechanism. One end of the linkage mechanism is connected to the drive assembly and can move with the drive assembly. When the linkage mechanism moves with the drive assembly, the angle between the linkage mechanism and the main shaft changes. The other end of the linkage mechanism is connected to the flipping support mechanism, and the end of the flipping support mechanism away from the linkage mechanism is connected to the drum body and can rotate relative to the drum body.

[0012] Furthermore, the drive assembly includes a sliding sleeve and a connecting block, wherein the sliding sleeve is fitted onto the main shaft and is capable of sliding along the axial direction of the main shaft; the two ends of the connecting block are respectively connected to the linkage mechanism and the sliding sleeve.

[0013] Furthermore, the linkage mechanism includes multiple connecting rods, and the flipping support mechanism includes multiple flipping support blocks. The multiple connecting rods correspond one-to-one with the multiple flipping support blocks, and different connecting rods are connected to their respective flipping support blocks.

[0014] Furthermore, the flipping support mechanism has a locking ring groove at the other end near the reverse packaging assembly. In the axial direction of the main shaft, the position where the linkage mechanism connects to the flipping support mechanism is located on the side of the locking ring groove away from the reverse packaging assembly.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0024] To address the difficulty in installing the capsule in existing air spring drums, this 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, which includes a main shaft 10, a locking ring assembly 20, a drive assembly 30, a reverse wrapping assembly 40, and a reverse wrapping capsule 50. At least a portion of the locking ring assembly 20 is movably mounted 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 with the locking ring groove 222 can move in the direction of increasing diameter of the main shaft 10 to lock with the steel ring. At least a portion of the drive assembly 30 is movably mounted on the main shaft 10 and can move axially along the main shaft 10. The drive assembly 30 is drively connected to the locking ring assembly 20. The reverse wrapping assembly 40 is located on the side of the locking ring assembly 20 near the end of the main shaft 10. The reverse wrapping assembly 40 is detachably sleeved on the main shaft 10, and at least a portion of the reverse wrapping assembly 40 is sleeved on the outer periphery of the drive assembly 30. The reverse wrapping capsule 50 is detachably connected to the reverse wrapping assembly 40, and one end of the reverse wrapping capsule 50 is sleeved on the locking ring assembly 20.

[0026] During installation, the reverse-packing capsule 50 of this invention is first connected to the reverse-packing assembly 40, and then the reverse-packing capsule 50 and the reverse-packing assembly 40 are together sleeved onto the main shaft 10 from one axial end. During disassembly, the reverse-packing capsule 50 and the reverse-packing assembly 40 are first removed from one axial end of the main shaft 10, and then the reverse-packing capsule 50 and the reverse-packing assembly 40 are separated. This makes the installation and disassembly of the reverse-packing capsule 50 easier and does not damage the structure of the reverse-packing capsule 50, thereby improving the service life of the reverse-packing capsule 50. One person can quickly install and disassemble it, saving labor costs and improving work efficiency.

[0027] like Figure 2As shown, the reverse packaging assembly 40 includes an air guide ring 41, a pressure plate 42, and a capsule support cylinder 43. The air guide ring 41 is located on the outer periphery of the main shaft 10, and at least a portion of the reverse packaging capsule 50 is located on the outer periphery of the air guide ring 41, and the air guide ring 41 can inflate the interior of the reverse packaging capsule 50. The pressure plate 42 is located on the side of the air guide ring 41 near the locking groove 222 in the axial direction of the main shaft 10. The first fixing part 51 of the reverse packaging capsule 50 is located between the pressure plate 42 and the air guide ring 41. The capsule support cylinder 43 is disposed on the side of the air guide ring 41 away from the pressure plate 42, and the second fixing part 52 of the reverse packaging capsule 50 is located between the capsule support cylinder 43 and the air guide ring 41. In this way, the air guide ring 41 can directly inflate the inside of the reverse capsule 50, ensuring good sealing inside the reverse capsule 50. This solves the problem in the prior art where the capsule's air nozzle and the support plate's vent need to be aligned, increasing the difficulty of capsule installation, and the capsule's air nozzle is prone to falling off during the capsule's installation onto the support plate, resulting in poor sealing.

[0028] It should be noted that in this application, the gas guide ring 41 has multiple evenly distributed outlet holes along its circumference. These outlet holes are all located inside the reverse capsule 50 and communicate with the interior of the reverse capsule 50. In this way, the multiple outlet holes evenly fill the interior of the reverse capsule 50 with gas.

[0029] like Figure 2 As shown, the reverse-packing assembly 40 also includes at least one fixing member 44. The fixing member 44 passes sequentially through the capsule support cylinder 43, the second fixing part 52, the air guide ring 41, and the first fixing part 51 and is connected to the pressure plate 42. In this way, after the fixing member 44 fixes the air guide ring 41, the pressure plate 42, the capsule support cylinder 43, and the reverse-packing capsule 50 into a whole, the whole is installed at one axial end of the main shaft 10, which ensures that the installation and removal of the reverse-packing capsule 50 is easier and will not damage the reverse-packing capsule 50.

[0030] Preferably, the fastener 44 is a screw.

[0031] like Figure 1 and 2 As shown, the reverse packaging assembly 40 also includes an inflation member 45. At least a portion of the inflation member 45 extends from the end of the capsule support cylinder 43 away from the air guide ring 41 into the capsule support cylinder 43 and communicates with the air guide ring 41. In this way, the inflation member 45 inflates gas through the air guide ring 41 into the interior of the reverse packaging capsule 50, supporting the reverse packaging capsule 50 to achieve reverse packaging of the rubber material.

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

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

[0034] like Figure 2 As shown, the locking ring assembly 20 includes a linkage mechanism 21 and a flipping support mechanism 22. One end of the linkage mechanism 21 is connected to the drive assembly 30 and can move with the drive assembly 30. When the linkage mechanism 21 moves with the drive assembly 30, the angle between the linkage mechanism 21 and the main shaft 10 changes. The other end of the linkage mechanism 21 is connected to the flipping support mechanism 22, and the end of the flipping support mechanism 22 away from the linkage mechanism 21 is connected to the drum body and can rotate relative to the drum body. Thus, when the drive assembly 30 drives the linkage mechanism 21 to rotate, the angle between the linkage mechanism 21 and the main shaft 10 gradually increases or decreases. The linkage mechanism 21 drives the flipping support mechanism 22 to flip around the end connected to the drum body, thereby locking the steel ring.

[0035] like Figure 2 As shown, the drive assembly 30 includes a sliding sleeve 31 and a connecting block 32. 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 connected to the linkage mechanism 21 and the sliding sleeve 31, respectively. Thus, when the steel rim needs to be locked, the sliding sleeve 31 slides along the axial direction of the main shaft 10 toward the drum body, thereby driving the connecting block 32 to slide along the axial direction of the main shaft 10 toward the drum body. The linkage mechanism 21 connected to the connecting block 32 rotates as the connecting block 32 slides, causing the angle between the linkage mechanism 21 and the main shaft 10 to gradually increase. The flipping support mechanism 22 flips away from the main shaft 10 to lock with the steel rim. When the tire needs to be removed after the wrapping is completed, the sliding sleeve 31 slides away from the drum body, thereby driving the connecting block 32 to slide away from the drum body. The linkage mechanism 21 connected to the connecting block 32 rotates as the connecting block 32 slides, causing the angle between the linkage mechanism 21 and the main shaft 10 to gradually decrease. The flipping support mechanism 22 flips towards the main shaft 10 until the flipping 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 linkage mechanism 21 includes multiple connecting rods 211, and the flipping support mechanism 22 includes multiple flipping support blocks 221. Each connecting rod 211 corresponds to one of the multiple flipping support blocks 221, and different connecting rods 211 are connected to their respective flipping support blocks 221. In this way, the multiple connecting rods 211 and the multiple flipping support blocks 221 drive the rubber material on the outer periphery of the inverted capsule 50 to move in the direction of increasing diameter of the main shaft 10, so as to lock with the steel ring.

[0037] Preferably, the multiple connecting rods 211 and the multiple flipping support blocks 221 are evenly spaced along the circumference of the main shaft 10 to ensure that the reverse-encased capsule 50 is subjected to balanced force in the circumferential direction.

[0038] like Figure 2 As shown, the flipping support mechanism 22 has a locking ring groove 222 at the other end near the reverse packaging assembly 40. In the axial direction of the main shaft 10, the connecting rod mechanism 21 is located on the side of the locking ring groove 222 away from the reverse packaging assembly 40. In this way, the flipping support mechanism 22 flips along the end connected to the drum body to ensure that the movement distance of the other end of the flipping support mechanism 22 with the locking ring groove 222 is as large as possible, thereby improving working efficiency.

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

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

[0041] 2) Apply adhesive material to the outer circumferential surface of the air spring drum;

[0042] 3) After the material is applied, the linkage mechanism 21 drives the flipping support mechanism 22 to flip in a direction away from the main shaft 10, so that the angle between the flipping support mechanism 22 and the main shaft 10 gradually increases, so as to support and lock the steel ring.

[0043] 4) The inflation component 45 inflates the reverse-packing capsule 50 through the air guide ring 41 to complete the reverse packaging;

[0044] 5) The linkage mechanism 21 drives the flipping support mechanism 22 to flip in the direction close to the main shaft 10, so that the included angle between the flipping support mechanism 22 and the main shaft 10 gradually decreases until the included angle is zero, and the tire body is removed.

[0045] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects: During the installation process of the reverse-packing capsule 50 in the present invention, the reverse-packing capsule 50 is first connected to the reverse-packing assembly 40, and then the reverse-packing capsule 50 and the reverse-packing assembly 40 are together sleeved on the main shaft 10 from one axial end. During the disassembly process of the reverse-packing capsule 50, the reverse-packing capsule 50 and the reverse-packing assembly 40 are first removed from one axial end of the main shaft 10, and then the reverse-packing capsule 50 and the reverse-packing assembly 40 are separated. This makes the installation and disassembly of the reverse-packing capsule 50 easier and will not damage the structure of the reverse-packing capsule 50, thereby improving the service life of the reverse-packing capsule 50. One person can quickly install and disassemble it, saving labor costs and improving work efficiency.
