[0002] The tire building machine is a special equipment for tire production that combines semi-finished parts (such as tread, sidewall, crown, rubber, carcass, etc.) into tire embryos according to process requirements during the tire manufacturing process. The mechanical building drum installed on the carcass side of the tire building machine is mainly used to implement the bonding and reverse packaging of carcass components such as the inner liner and sidewall rubber. The mechanical drum on the carcass side of the tire building machine uses a locking ring capsule, which is a consumable part. After damage, the existing replacement method is usually to disassemble the drum and then gradually disassemble and replace it;

[0003] It has been found in actual use that the existing mechanical drum lock ring capsule is inconvenient to replace:

[0004] When replacing the inner bladder, the two halves of the carcass drum need to be removed from the main shaft at the same time, and the center cover needs to be removed. This is not only complicated but also takes a long time to replace, which seriously affects the normal operation of the production line and reduces production efficiency.

[0005] Therefore, the present application provides a tire building machine mechanical drum replacement auxiliary device to meet the needs. Utility Model Content

DETAILED DESCRIPTION

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4 A tire forming machine mechanical drum replacement auxiliary device is shown, and an embodiment of the utility model provides: a fixed seat 1, a connecting seat 2, a handle 3, a fixed block 4, a connecting frame 5, a torsion spring 6, a movable block 7 and a limiting sleeve 8. The front end of the fixed seat 1 is provided with a connecting seat 2, and the handles 3 are installed at the upper and lower ends of the side of the fixed seat 1 away from the connecting seat 2. The fixed block 4 is installed on the surface of the fixed seat 1, and the connecting frame 5 is installed at one end of the fixed block 4. The torsion spring 6 is installed on the inner side of the connecting frame 5, and the movable block 7 is installed on the other end of the connecting frame 5. The outer end of the fixed seat 1 is installed with a limiting sleeve 8.

[0029] In the present embodiment, the fixing seat 1 and the connecting seat 2 are both made of stainless steel, and the fixing seat 1 is cylindrical, and the connecting seat 2 is conical. The cylindrical fixing seat 1 can be sleeved on the outer end of the mechanical drum when installing and disassembling the locking ring capsule of the mechanical drum. Pulling the handle 3 drives the fixing seat 1 to move, and the diameter of the conical connecting seat 2 gradually decreases, so that when the locking ring capsule is flipped and sleeved on the connecting seat 2, the contact area with the locking ring capsule can be reduced, thereby reducing the friction with the locking ring capsule. Therefore, when installing the locking ring capsule, the capsule can be directly taken off and sleeved on the drum, making it easier to install the locking ring capsule and increasing the installation speed of the locking ring capsule.

[0030] In this embodiment, the limiting sleeve 8 is in a circular ring shape, and the inner diameter of the limiting sleeve 8 is larger than the diameter of the fixing seat 1. The limiting sleeve 8 can move laterally on the fixing seat 1, and can be sleeved on the outer end of the locking ring capsule through the limiting sleeve 8.

[0031] In this embodiment, the limiting sleeve 8 is made of rubber material, and the limiting sleeve 8 made of rubber material can be flexibly fitted on the outer end of the locking ring capsule.

[0032] In this embodiment, two groups of fixed blocks 4, connecting frames 5, torsion springs 6 and movable blocks 7 are provided, and the two groups of fixed blocks 4, connecting frames 5, torsion springs 6 and movable blocks 7 are respectively located on the left and right sides of the outer end of the fixed base 1.

[0033] In this embodiment, the fixed block 4 is arranged in two sections, and the front end of the fixed block 4 is attached to the surface of the fixed seat 1, and the rear end of the fixed block 4 is tilted and tilted outward, so that there is a gap between the rear end of the fixed block 4 and the fixed seat 1, so that the movable block 7 can be turned outward.

[0034] In this embodiment, the movable block 7 is in the shape of an elongated strip, and is movably connected to the fixed block 4 via the connecting frame 5 and the torsion spring 6. The movable block 7 is naturally attached to the surface of the fixed seat 1 by the tensile force of the connecting frame 5 and the torsion spring 6.

[0035] In this embodiment, the movable block 7 extends outward from one side of the fixed block 4 to the edge of the connecting seam between the fixed seat 1 and the connecting seat 2. During installation, the movable block 7 is pulled open, and then the limiting sleeve 8 is put on the outer end of the locking ring capsule. The pulling force of the torsion spring 6 clamps the movable block 7 on the outer end of the limiting sleeve 8, thereby fixing the locking ring capsule in the limiting sleeve 8 to prevent the locking ring capsule from slipping out, making the locking ring capsule more stable when replaced.
