Description

Technical Field

[0001] The utility model relates to the technical field of tire manufacturing, in particular to a transfer ring device. Background Art

[0002] In the prior art, during the tire production process, after a first-stage molding machine has completed molding the tire barrel, a transfer ring moves to the first-stage molding machine to unload the tire barrel from the first-stage molding machine. The transfer ring then clamps the tire barrel and transfers it to the winding and shaping drum on the second-stage molding machine for belt layer bonding to finally form a tire blank.

[0003] Among them, in the process of unloading the tire barrel from a molding machine, the tiles of the transfer ring will first hug the tire barrel, and the tire barrel at this time is also tightly fitted on the molding folding drum of a molding machine. After the transfer ring hugs the tire barrel, in order to separate the tire barrel from the molding machine, the molding folding drum will be folded to make it shrink directly. However, when the diameter of the folding drum begins to shrink, the folding drum of the molding machine needs to rotate 3°-5°, which will drive the tire barrel tightly fitted with it to rotate 3°-5°, and because the tiles on the transfer ring are fixed arc tiles, when the transfer ring hugs the tire barrel, the fixed arc tiles will fit tightly with the tire barrel, and when the tire barrel rotates 3°-5° with the folding drum of the molding machine, the tire barrel will generate friction with the tiles, and then the high-pressure points between the tire barrel and the tiles will continue to contact, thereby causing wear and damage to the tire barrel, reducing the qualified rate of the tire.

[0025] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0026] Please refer to Figures 1 to 6According to an embodiment of the utility model, a transfer ring device is provided for transferring a tire barrel, the transfer ring device comprising: a transfer ring body 1 and a plurality of pad assemblies 2, the transfer ring body 1 being movably arranged; a working space 10 is provided inside the transfer ring body 1; a plurality of pad assemblies 2 are arranged around the circumferential direction of the transfer ring body; a plurality of pad assemblies 2 are located in the working space, a clamping surface 200 of each pad assembly 2 is arranged toward the axial direction of the transfer ring body 1, and a clamping surface 200 of each pad assembly 2 is used to enclose a clamping space for clamping the tire barrel; wherein the pad assembly 2 has a movable portion 22 that is movably connected; at least a portion of the clamping surface 200 of the pad assembly 2 is located on the movable portion 22, and when at least a portion of the clamping surface 200 of the pad assembly 2 located on the movable portion 22 abuts against the tire barrel, at least a portion of the movable portion 22 rotates relative to the tire barrel; or, at least a portion of the movable portion 22 moves along the radial direction of the clamping space.

[0027] It can be seen that the transfer ring device provided by the utility model is provided by simply setting a transfer ring body 1 and a plurality of tile assemblies 2. The transfer ring body 1 can be movably provided, and the plurality of tile assemblies 2 are provided in the working space 10 of the transfer ring body 1. Then, the transfer ring device can be movable through the movable setting of the transfer ring body 1. At the same time, the plurality of tile assemblies 2 can be used to clamp the tire barrel, so that the transfer ring device can unload and transfer the tire barrel. At the same time, there is a movable part 22 on the tile assembly, and at least part of the clamping surface 200 of the tile assembly 2 is located on the movable part 22. When at least part of the clamping surface of the tile assembly 2 located on the movable part 22 abuts against the tire barrel, at least part of the movable part 22 rotates relative to the tire barrel; or, at least part of the movable part 22 moves along the radial direction of the clamping space. Thus, when multiple tile assemblies hold the tire barrel, at least part of the clamping surface of the tile assembly 2 on the movable part can fit with the tire barrel, and each movable part 22 plays the role of clamping the tire barrel and fixing the tire barrel, which is convenient for the folding drum of the molding machine to separate from the tire barrel. At the same time, when multiple tile assemblies 2 hold the tire barrel, and the tire barrel rotates a certain angle with the folding drum of the molding machine, the tire barrel will drive at least part of the movable part 22 to rotate relative to the tire barrel, thereby avoiding the problem of tire barrel wear and damage caused by friction between the tire barrel and the clamping surface of the tile due to rotation, improving the production efficiency of the tire barrel and improving the qualified rate of the tire. In addition, when the tire barrel stops rotating, at least part of each movable part 22 will move along the radial direction of the clamping space, thereby achieving that the clamping surface of the tile assembly 2 can fit closely with the tire barrel, so that multiple tile assemblies 2 can clamp (i.e., hold) the tire barrel, unload the tire barrel from the first-stage molding machine and transfer it to the winding and shaping drum of the second-stage molding machine. The transfer ring device has a simple structure and is easy to operate. It can effectively solve the technical problem in the prior art that when the transfer ring clamps the tire barrel, friction will occur between the tire barrel and the fixed arc tile when the tire barrel rotates with the forming folding drum, thereby causing wear and damage to the tire barrel.

[0028] Specifically, the cross section of the transfer ring body 1 is circular, the cross section of the working space 10 of the transfer ring body 1 is circular, and the axis extension direction of the transfer ring body 1 coincides with the axis extension direction of the working space 10 of the transfer ring body 1. The area of ​​the working space 10 of the transfer ring body 1 is larger than the area of ​​the maximum clamping space, thereby enabling each shoe assembly 2 to adjust the size of the clamping space, thereby adapting to changes in the diameter of the tire barrel and facilitating unloading of the tire barrel.

[0029] Specifically, the cross-sectional area of ​​the tire barrel is circular, so the shape of the clamping space surrounded by the clamping surfaces 200 of each shoe assembly 2 is also circular.

[0030] Specifically, the transfer ring device also includes: a connecting frame 6, the connecting frame 6 is arranged on the outer wall of the transfer ring body 1, one end of the connecting frame 6 is fixedly connected to the transfer ring body 1, and the other end of the connecting frame 6 is movably arranged on the guide rail of the tire forming equipment. The transfer ring body 1 moves along the extension direction of the guide rail of the tire forming equipment through the connecting frame 6, so that the transfer ring device can unload the tire barrel from the first-stage forming machine and transfer it to the winding and shaping drum of the second-stage forming machine.

[0031] Specifically, the connecting frame 6 and the transfer ring body 1 are integrally formed.

[0032] Specifically, the transfer ring device is arranged between the first-stage forming machine and the second-stage forming machine, and the transfer ring body 1 is respectively arranged concentrically with the forming machine folding drum on the first-stage forming machine and the winding and shaping drum of the second-stage forming machine.

[0033] Specifically, the transfer ring body 1 moves downward or upward by a maximum of 20 MM in the vertical direction, so that the transfer ring body 1 is respectively arranged concentrically with the forming machine folding drum on the first-stage forming machine and the winding and shaping drum of the second-stage forming machine.

[0034] In this embodiment, if Figure 1 , Figure 2 and Figure 6 As shown, the tile assembly 2 includes: a tile body 21, the tile body 21 extends along a preset arc trajectory, a mounting through hole 210 is provided on the tile body 21, and the mounting through hole 210 extends along the extension direction of the tile body 21; at least a part of the movable part 22 is movably arranged in the mounting through hole 210.

[0035] The preset arc trajectory extension of the tile body 21 refers to that the extension direction of the tile body 21 is extended according to the arc trajectory pre-designed for the tile body 21 .

[0036] Specifically, Figure 6As shown, the pad body 21 has a first clamping surface 211 for clamping the tire barrel and a first mounting surface 212 for connecting to the structure to be connected, and the first clamping surface 211 and the first mounting surface 212 are arranged opposite to each other; the movable part 22 includes a rotating bearing 221, and the rotating bearing 221 can be movably arranged in the mounting through hole 210, and the axial direction of the rotating bearing 221 is consistent with the axial direction of the transfer ring body; at least part of the rotating bearing 221 protrudes from the first clamping surface 211 of the pad body 21, and the side of the rotating bearing 221 located in the clamping space is the second clamping surface 2210; the first clamping surface 211 and the second clamping surface 2210 form the clamping surface 200 of the pad assembly 2; wherein, when the rotating bearing 221 abuts against the tire barrel, the rotating bearing 221 rotates relative to the tire barrel; or, the rotating bearing 221 moves along the radial direction of the clamping space. With such a structural arrangement, when the transfer ring device is to unload the tire barrel, the rotating bearing 221 in each tile assembly 2 plays a clamping role. When the tire barrel rotates, the rotating bearing 221 can rotate relative to the tire barrel, thereby effectively reducing the friction between the tire barrel and the tile, reducing the risk of damage and wear of the tire barrel, extending the service life of the equipment, improving the production efficiency of the tire barrel and improving the qualified rate of the tire. At the same time, by providing the rotating bearing 221, the problem of tire barrel deformation caused by the rotation of the tire barrel can be avoided.

[0037] Specifically, at least part of the rotating bearing 221 protrudes from the first clamping surface 211 of the shoe body 21 and the first mounting surface 212 of the shoe body 21 , respectively, and there is a gap between the inner wall of the mounting through hole 210 and the rotating bearing 221 .

[0038] Specifically, when the transfer ring device unloads the tire barrel from the folding drum of the molding machine on the first stage molding machine, the plurality of tile assemblies 2 will first hold the tire barrel. After holding the tire barrel, the tire barrel will rotate a certain angle with the folding drum of the molding machine. When the tire barrel rotates, the tire barrel will drive the rotating bearing 221 to rotate relative to the tire barrel by a certain angle, thereby avoiding the tire barrel from being damaged by friction between the tire barrel and the clamping surface of the tile due to rotation, thereby improving the production efficiency of the tire barrel and the qualified rate of the tire. When the tire barrel stops rotating, the diameter of the folding drum of the molding machine on the first stage molding machine is reduced, and the transfer ring device will apply a certain pressure to make the rotating bearing 221 in each tile assembly 2 move along the radial direction of the clamping space, thereby making the clamping surface 200 of the tile assembly 2 fit closely with the tire barrel, thereby enabling the plurality of tile assemblies 2 to clamp (i.e. hold) the tire barrel, unload the tire barrel from the first stage molding machine and transfer it to the winding and shaping drum of the second stage molding machine.

[0039] In this embodiment, if Figure 6As shown, the movable part 22 also includes: a support shaft 222, which is movably arranged on the first mounting surface 212 along the radial direction of the clamping space, and the support shaft 222 extends along the axial direction of the rotating bearing 221. The rotating bearing 221 is sleeved on the support shaft 222, and the rotating bearing 221 rotates around the axis of the support shaft 222; when the rotating bearing 221 abuts against the tire barrel, the support shaft 222 drives the rotating bearing 221 to move along the radial direction of the clamping space.

[0040] Specifically, the rotating bearing 221 is rotatably sleeved on the support shaft 222, so as to be rotatably arranged in the mounting through hole 210 through the support shaft 222. When the first clamping surface 211 of the pad body 21 needs to contact the tire barrel, the support shaft 222 drives the rotating bearing 221 to move along the radial direction of the clamping space.

[0041] In this embodiment, if Figure 6 As shown, the tile assembly 2 further includes: a fixing frame 23, the fixing frame 23 is placed on the first mounting surface 212, the two ends of the fixing frame 23 are respectively fixed on the first mounting surface 212, and a placement cavity 230 is formed between the fixing frame 23 and the first mounting surface 212; the placement cavity 230 extends along the radial direction of the clamping space, and at least part of the support shaft 222 is arranged in the placement cavity 230; wherein, a fixing frame 23 is respectively provided near the two ends of the support shaft 222, and the two ends of the support shaft 222 are respectively arranged in the placement cavity 230 to limit the movement direction of the support shaft 222. Such a structural setting is adopted to limit the movement trajectory of the support shaft 222 through the fixing frame 23.

[0042] Specifically, there are at least two fixing frames 23, and the two fixing frames 23 are installed on the first mounting surface 212 at intervals along the extension track of the support shaft 222, and then the two ends of the support shaft 222 are respectively inserted into the placement cavity 230 corresponding to each fixing frame 23. When the support shaft 222 drives the rotating bearing 221 to move along the radial direction of the clamping space, the placement cavity 230 is used to limit the movement of the support shaft 222 along the extension direction of the tile body 21, and also limit the distance that the support shaft 222 moves along the radial direction of the clamping space.

[0043] Specifically, the pad assembly 2 further includes an elastic member 24, which is disposed in the placement cavity 230, extends in the radial direction of the clamping space, one end of the elastic member 24 abuts against the support shaft 222, and the other end of the elastic member 24 abuts against the inner wall of the placement cavity 230. With such a structural arrangement, by disposing the elastic member 24 in the placement cavity 230, a certain force is applied to the support shaft 222 by the self-compression force of the elastic member 24, so as to ensure that the rotating bearing 221 and the tire barrel can always fit together during the process of unloading and transferring the tire barrel by the transfer ring device. In addition, after the transfer ring device completes the transfer (i.e., when the transfer ring device does not clamp the tire barrel), the rotating bearing 221 and the support shaft 222 are restored to the state when they are installed on the pad body 21 (i.e., the initial state of the rotating bearing 221 and the support shaft 222) by the restoring elastic force of the elastic force.

[0044] Specifically, the elastic member 24 is a pressure spring. When the rotating bearing 221 abuts against the tire tube, the rotating bearing 221 will be subjected to a certain force, which will be transmitted to the pressure spring through the support shaft 222. The pressure spring will be compressed and deformed, and a certain pressure will be applied to the rotating bearing 221 through its own compression force, so that the rotating bearing 221 and the tire tube are always in abutment. When the first clamping surface of the pad body 21 abuts against the tire tube, the rotating bearing 221 will move along the radial direction of the clamping space, and the pressure spring will be compressed and deformed. At the same time, the pressure spring will also apply a certain pressure to the rotating bearing 221, so that when the first clamping surface of the pad body 21 is tightly fitted with the tire tube, the rotating bearing 221 and the tire tube are also tightly fitted. After the transfer ring device completes the transfer (that is, the transfer ring device does not clamp the tire tube), the restoring elastic force of the pressure spring is used to restore the rotating bearing 221 and the support shaft 222 to the state when they are installed on the pad body 21 (that is, the initial state of the rotating bearing 221 and the support shaft 222).

[0045] In this embodiment, if Figure 6 As shown, the pad assembly 2 further includes: a pressure regulating member 25, which is movably arranged on the fixing frame 23 along the radial direction of the clamping space, one end of the pressure regulating member 25 passes through the side of the fixing frame 23 away from the first mounting surface 212 and is placed in the placement cavity 230, and one end of the pressure regulating member 25 abuts against one end of the elastic member 24 away from the support shaft 222, so that the compression force of the elastic member 24 can be adjusted by reciprocating the pressure regulating member 25 along the radial direction of the clamping space. With such a structural arrangement, the compression force of the elastic member can be adjusted according to actual conditions by arranging the pressure regulating member 25.

[0046] Specifically, one end of the elastic member 24 abuts against the support shaft 222 , the other end of the elastic member 24 is connected to one end of the pressure regulating member 25 located in the placement cavity 230 , and the other end of the elastic member 24 abuts against the inner wall of the placement cavity 230 through the pressure regulating member 25 .

[0047] Specifically, at least a portion of the outer wall of the pressure adjusting member 25 is provided with an external thread, and a threaded hole matching the external thread is provided on the side of the fixing frame 23 away from the first mounting surface 212, so that the pressure adjusting member 25 can be connected to the fixing frame 23 through threaded cooperation, and the pressure adjusting member 25 can be moved along the radial direction of the clamping space by rotating the pressure adjusting member 25 to adjust the compression force of the elastic member.

[0048] Specifically, Figure 6 As shown, there are multiple support shafts 222, and the multiple support shafts 222 are arranged at intervals along the extension direction of the tile body 21; multiple rotating bearings 221 are sleeved on each support shaft 222, and the multiple rotating bearings 221 of each support shaft 222 are arranged at intervals along the extension direction of the support shaft 222; fixed frames 23 are respectively provided at both ends of each support shaft 222; multiple mounting through holes 210 are provided on the tile body 21, and each mounting through hole 210 is arranged one-to-one with each rotating bearing 221. With such a structural setting, by setting multiple rotating bearings 221, the dispersed pressure can be increased, and the problem of wear and damage caused by continuous contact of the high-pressure point between the tire barrel and the tile is further avoided. At the same time, by setting multiple rotating bearings 221, the clamping capacity can be improved.

[0049] Specifically, Figure 6 As shown, a fixing frame 23 is provided between each adjacent two rotating bearings of the plurality of rotating bearings 221 of each supporting shaft 222; there are a plurality of elastic members 24 and a plurality of pressure adjusting members 25, and each elastic member 24 and each pressure adjusting member 25 are respectively provided in one-to-one correspondence with each fixing frame 23. With such a structural setting, by providing a plurality of fixing frames 23 and providing a plurality of elastic members 24 and a plurality of pressure adjusting members 25 corresponding to the plurality of fixing frames 23, the ability to limit the movement track of the supporting shaft 222 can be further improved, and the supporting shaft 222 can be subjected to uniform force, and it can also be ensured that each rotating bearing 221 can always fit with the tire barrel.

[0050] Specifically, there are two support shafts 222, which are arranged at intervals along the extension direction of the pad body 21, and three rotating bearings 221 are arranged at intervals on each support shaft 222 along the axial direction of the support shaft 222. A fixing frame 23 is respectively arranged at both ends of each support shaft 222, and a fixing frame 23 is arranged between two adjacent rotating bearings 221, and each fixing frame 23 is installed on the first mounting surface 212. Six mounting through holes 210 are arranged at intervals on the pad body 21, and the six mounting through holes 210 are arranged one by one corresponding to the six rotating bearings 221. The fixing frame 23 arranged between two adjacent rotating bearings 221 is located between two adjacent mounting through holes 210.

[0051] Specifically, when the transfer ring device unloads the tire barrel from the folding drum of the molding machine on a section of the molding machine, first, multiple pad assemblies 2 will hold the tire barrel. When each pad assembly 2 clamps the tire barrel, the compression force of the elastic member 24 is used to make multiple rotating bearings 221 on each pad assembly 2 abut against the tire barrel.

[0069] The utility model provides a transfer ring device for transferring a tire barrel, the transfer ring device comprising: a transfer ring body 1 and a plurality of tile assemblies 2, the transfer ring body 1 being movably arranged; a working space 10 being provided inside the transfer ring body 1; a plurality of tile assemblies 2 being arranged around the circumferential direction of the transfer ring body; a plurality of tile assemblies 2 being located in the working space, a clamping surface 200 of each tile assembly 2 being arranged toward the axial direction of the transfer ring body 1, and a clamping surface 200 of each tile assembly 2 being arranged to enclose a clamping space for clamping the tire barrel; wherein the tile assembly 2 has a movable portion 22 that is movably connected; at least a portion of the clamping surface 200 of the tile assembly 2 is located on the movable portion 22, and when at least a portion of the clamping surface 200 of the tile assembly 2 located on the movable portion 22 abuts against the tire barrel, at least a portion of the movable portion 22 rotates relative to the tire barrel; or, at least a portion of the movable portion 22 moves along the radial direction of the clamping space.

[0070] It can be seen that the transfer ring device provided by the utility model is provided by simply setting a transfer ring body 1 and a plurality of tile assemblies 2. The transfer ring body 1 can be movably provided, and the plurality of tile assemblies 2 are provided in the working space 10 of the transfer ring body 1. Then, the transfer ring device can be movable through the movable setting of the transfer ring body.

Furthermore, when a plurality of tile assemblies clamp the tire barrel (i.e., each tile assembly does not hold the tire barrel tightly), at least a portion of the clamping surface of the tile assembly 2 on the movable portion can fit the tire barrel, and each movable portion 22 plays a role in clamping the tire barrel. At the same time, when a plurality of tile assemblies 2 clamp the tire barrel (i.e., each tile assembly does not hold the tire barrel tightly), and the tire barrel rotates a certain angle with the folding drum of the forming machine, the tire barrel will drive at least a portion of the movable portion 22 to rotate relative to the tire barrel, thereby avoiding the problem of tire barrel wear and damage caused by friction between the tire barrel and the clamping surface of the tile due to rotation, thereby improving the production efficiency of the tire barrel and the qualified rate of tires. In addition, when the tire drum stops rotating, at least part of each movable part 22 will move along the radial direction of the clamping space, thereby achieving a close fit between the clamping surface of the tile assembly 2 and the tire drum, so that multiple tile assemblies 2 can clamp (i.e., hold) the tire drum, unload the tire drum from the first-stage molding machine and transfer it to the winding and shaping drum of the second-stage molding machine. The transfer ring device has a simple structure and is easy to operate, and can effectively solve the technical problem that when the transfer ring in the prior art is clamping the tire drum, when the tire drum rotates with the forming folding drum, friction will occur between the tire drum and the fixed arc tile, thereby causing wear and damage to the tire drum.
