[0002] The belt drum is the core component of the tire building machine. Its working process is as follows: after the belt drum is propped up, the rubber material is bonded and rolled. After rolling is completed, the belt transfer ring clamps the barrel, the belt drum shrinks, and the belt transfer ring transfers the barrel to the next station. In the traditional tire building machine belt bonding process, there is a cylindrical drum body that can achieve radial expansion and contraction as the bonding support surface of the rubber material, and then the No. 1 belt layer, No. 2 belt layer, No. 3 belt layer, No. 4 belt layer and tread are bonded and rolled in turn. Because the width of each layer of rubber material is different, when all the rubber materials are bonded together, some parts of the rubber materials are suspended. The tread of the area with the same width can be tightly bonded with the belt layer, and the tread of the suspended area cannot be bonded with the belt layer below, causing the treads on both sides to be suspended. When rolling, the tread seams in the suspended area cannot be tightly compacted. Utility Model Content

[0025] In order to solve the problem that the tread joint cannot be tightly compacted in the prior art, the utility model provides a belt layer drum tread joint laminating auxiliary device and a forming machine.

[0026] like Figures 1 to 4 A belt layer drum tread joint bonding auxiliary device shown in the figure includes a support member 10, a transmission mechanism 20, and a driving member 30 arranged on a drum body 50. The support member 10 can be axially moved relative to the drum body 50. There are multiple support members 10, and support members 10 are arranged at both axial ends of the tread 60. The support member 10 has a supporting position located between the drum body 50 and the tread 60 and an avoidance position between the drum body 50 and the tread 60. Each support member 10 is driven and connected to the transmission mechanism 20, and the driving member 30 is driven and connected to the support member 10 and / or the transmission mechanism 20. During bonding, the driving member 30 drives the support member 10 to synchronously move axially to the supporting position to support the tread 60.

[0027] In this embodiment, by arranging the support member 10 on the drum body 50, the support member 10 can provide support for the tread 60 during lamination, thereby solving the problem that the joint of the tread 60 cannot be tightly compacted due to the partial suspension of the tread 60. Specifically, the support member 10 is arranged at both ends of the tread 60 in the axial direction, and can move along the axial direction of the drum body 50 under the drive of the driving member 30, so that the support member 10 can move to the suspended area of ​​the tread 60 when the tread 60 is lamination to play a supporting role, so that the head and tail of the tread 60 form a full circle for subsequent seaming and pressing. When lamination is not required, the driving member 30 drives the support member 10 to move out of the suspended area of ​​the tread 60 to avoid other components. The above arrangement enables the support member 10 to effectively support the suspended part of the tread 60, so that the tread joint can be tightly compacted, and the processing effect is guaranteed.

[0028] It should be noted that the suspended area of ​​the tread 60 refers to Figure 1 The left and right sides of the tread 60 are the areas where the tread 60 is wider than the cord layer.

[0029] In this embodiment, the driving member 30 is connected to the supporting member 10 by driving. When the driving member 30 drives the connected supporting member 10 to move, the connected supporting member 10 drives the other supporting members 10 except the connected supporting member 10 to move synchronously through the transmission mechanism 20. Specifically, the driving member 30 is connected to one or a part of the supporting members 10, and the other end of this part of the supporting members 10 is connected to the transmission mechanism 20, and the other supporting members 10 are driven to move synchronously through the transmission mechanism 20, so that all the supporting members 10 can act synchronously in the supporting position and exit the supporting position. Of course, in addition to the above-mentioned setting method, the driving member 30 can also be connected to the transmission mechanism 20 by driving, and the power can be transmitted to each supporting member 10 respectively through the transmission mechanism 20 to realize the synchronous action of the supporting members 10.

[0030] In this embodiment, the transmission mechanism 20 includes a gear 21 and a plurality of rack structures 22. The rack structures 22 are connected to the support member 10 and move synchronously with the support member 10. Different rack structures 22 are connected to different supports 10. The gear 21 meshes with the rack structure 22. The driving member 30 is drivingly connected to at least one of the support member 10, the gear 21 or the rack structure 22, and drives the support member 10 to move. Based on the above, in this embodiment, the power of the driving member 30 is transmitted to other supports 10 through the support member 10 and the transmission mechanism 20. In this embodiment, the driving member 30 is drivingly connected to the support member 10. This embodiment adopts the method of setting two support members 10 and two rack structures 22. Specifically, one end of the two rack structures 22 is fixed to the two support members 10 respectively, and the other end is meshed with the gear 21 respectively, and the driving member 30 is connected to one of the support members 10 by driving. When the driving member 30 drives one of the support members 10, the support member 10 drives the other support member 10 through the transmission of the rack structure 22, the gear 21 and the other rack structure 22 thereon, thereby driving the other support member 10 to move synchronously. Of course, when the power of the driving member 30 is transmitted to the support member 10 through the transmission mechanism 20, the driving member 30 can be connected to the gear 21 or the rack structure 22 by driving. Alternatively, the driving member 30 can be connected to multiple driving of the support member 10, the gear 21 or the rack structure 22 at the same time, or multiple driving members 30 can be connected to different components respectively. In this case, the consistency between the driving members 30 needs to be ensured. In addition to the method of providing two support members 10, more support members 10 may also be provided. Multiple support members 10 may be provided at both ends of the tread 60, thereby increasing the coverage of the width.

[0031] Preferably, the rack structure 22 connected to the support members 10 at both ends of the tread 60 in this embodiment is meshed with the same gear 21, that is, the two rack structures 22 of this embodiment are meshed with the same gear 21 at the same time, thereby ensuring the synchronous movement of the two rack structures 22, thereby ensuring the consistency of the movement of the support members 10 at both ends. Of course, multiple gears 21 can also be set, and the rack structure 22 can also be meshed with different gears 21, and the gears 21 are meshed with each other, thereby driving the movement of multiple rack structures 22. The gear 21 of this embodiment is fixed to the drum body 50 through components such as a rotating shaft and a bearing, thereby ensuring smooth rotation.

[0032] In this embodiment, the axial movement directions of the support members 10 at both ends of the tread 60 are opposite, so that when the two support members 10 act synchronously, the two support members 10 can move between the support position and the avoidance position at the same time, thereby realizing simultaneous support and simultaneous avoidance at both ends of the tread 60. In addition to the above-mentioned arrangement of the support members 10, the rack structure 22 connected to the support members 10 at both ends of the tread 60 is located on the two opposite sides of the gear 21 in the circumferential direction, that is, the rack structures 22 are symmetrically arranged on the two opposite sides of the gear 21 in the circumferential direction to mesh with it, on the one hand, the two support members 10 connected to the rack structure 22 can move synchronously, so that the movement directions of the two support members 10 are opposite, so that the two support members 10 can approach or move away from the tread 60 at the same time, and on the other hand, the two rack structures 22 do not affect each other, which can ensure the reliability of movement.

[0033] In this embodiment, the belt layer drum tread joint bonding auxiliary device further includes a connecting member 40, and the connecting member 40 can be a connecting block or the like. Figure 1 As shown, the connecting member 40 is connected to the output end of the driving member 30 and is connected to the supporting member 10. In this embodiment, the connecting member 40 is fixed at Figure 3 On the support member 10 on the middle right side, the driving member 30 drives the connecting member 40 to move axially along the drum body 50 so that the support member 10 moves axially along with the connecting member 40 to achieve the switching of the support member 10 between the supporting position and the avoiding position.

[0034] In this embodiment, the driving member 30 is a cylinder, and the driving axis of the cylinder is parallel to the axis of the drum body 50, so that the movement direction of the support member 10 driven by the cylinder is parallel to the axis of the drum body 50, thereby realizing the movement of the support member 10 between the supporting position and the avoidance position. Preferably, the cylinder is arranged inside the drum body 50 to avoid other components outside the drum body 50. At the same time, the transmission mechanism 20 is also arranged inside the drum body 50, and the rotation axis of the gear 21 is perpendicular to the axis of the drum body 50, so that the moving direction of the rack structure 22 and the support member 10 is parallel to the axial direction of the drum body 50, so that the support member 10 can act on the suspended area of ​​the tread 60 to compact the joint of the tread 60.

[0035] In this embodiment, the support member 10 is a support sleeve, which is arranged on the outer peripheral side of the drum body 50 and expands and contracts radially synchronously with the drum body 50. On the one hand, the support sleeve can move axially along the drum body 50 to the support position, and the inner side of the support sleeve can cooperate with the transmission mechanism 20, so that the position of the support sleeve can be adjusted according to the width of the belt layer and the tread 60, so as to support the suspended area of ​​the tread 60 close to the outer peripheral side of the drum body 50. On the other hand, the support sleeve can move radially with the drum body 50 to adapt to treads 60 and cord layers of different diameters.

[0036] The present embodiment also provides a forming machine, including a drum body 50 and the above-mentioned belt layer drum tread joint fitting auxiliary device, the support member 10 of the belt layer drum tread joint fitting auxiliary device is sleeved on the outside of the drum body 50, and can move along the axial direction of the drum body 50, so that the belt layer drum tread joint fitting auxiliary device can provide support for the suspended area of ​​the tread 60, so that the material head and tail of the tread 60 form a full circle to facilitate subsequent seaming and pressing.

[0037] The use process of the belt layer drum tread joint bonding auxiliary device in this embodiment is as follows: Figure 4 As shown, the cylinder is extended, and two support members 10 are respectively located on both sides of the drum body 50. The drum body 50 is expanded to the required diameter, and the No. 1 belt layer is attached to the surface of the drum body 50, the No. 2 belt layer is attached to the surface of the No. 1 belt layer, the No. 3 belt layer is attached to the surface of the No. 2 belt layer, and the No. 4 belt layer is attached to the surface of the No. 3 belt layer. Figure 3 As shown, the cylinder contracts, thereby driving the connecting member 40, the right support member 10, and the right rack structure 22 to move to the left. The right rack structure 22 engages with the gear 21 to enable the left rack structure 22 to move to the right synchronously, thereby causing the left support member 10 to move to the right at the same time. The two support members 10 move synchronously to both sides of the belt layer to support the suspended part of the tread 60, adhere the tread 60 to the surface of the fourth belt layer, and roll the joint area of ​​the tread 60. The belt layer transfer ring moves to the position above the drum body 50, the drum body 50 contracts radially, and the belt layer transfer ring takes away the composite part after the tread 60 and the belt layer rubber are adhered. Then, the cylinder extends out, thereby driving the connecting member 40, the right support member 10, and the right rack structure 22 to move to the right, and the right rack structure 22 drives the left rack structure 22 to move to the left by meshing with the gear 21, thereby causing the left support member 10 to move to the left at the same time, and the two support members 10 move synchronously to the edge of the drum body 50 to wait for the next rubber bonding.
