Description

Technical Field

[0001] This utility model relates to the field of bonding drum technology, and in particular to a bonding drum used in the production of engineering tires. Background Technology

[0002] Tire manufacturing bonding drums are devices used in tire manufacturing to bond tire carcass materials onto drum-shaped molds. Their main function is to tightly bond the inner liner, carcass layers, and other materials onto the drum-shaped molds, ensuring uniform bonding of each layer of the tire structure, thereby improving tire quality and performance. Bonding drums typically consist of a main shaft, cylinder assembly, guide plate, and support plate. During operation, the cylinder assembly controls the expansion and contraction of the drum, causing the inner liner to be radially stretched and evenly and tightly attached to the drum, thus ensuring bonding quality.

[0003] The bonding drum has many internal parts, a complex structure, and high cost. When it is necessary to process tires of different specifications and disassemble and replace them, the operation is cumbersome and time-consuming. Therefore, we propose a bonding drum for the production of engineering tires. Utility Model Content

Grooves 102 are provided on both sides of the surface of the connecting shaft 103, and there are multiple sets of grooves 102. The second rod 106 is fixedly installed in the middle of the surface of the connecting shaft 103, and there are multiple sets of second rods 106. The second rod 106 is tubular, and the first rod 104 is embedded in the upper surface of each second rod 106. A spring 107 is sleeved and connected between the first rod 104 and the second rod 106. One end of the spring 107 is fixed to the surface of the first rod 104, and the other end is fixed to the surface of the second rod 106.

[0023] In a preferred embodiment, the main shaft 2 includes a drive motor 201, a motor shaft 202, a first threaded rod 203, a second threaded rod 204, a movable shaft 205, and a limiting plate 206. The motor shaft 202 is fixedly mounted on one side surface of the drive motor 201. The drive motor 201 is a forward and reverse motor, model ZGB37RG. The first threaded rod 203 is fixedly mounted on one side surface of the motor shaft 202. The limiting plate 206 is fixedly mounted on one side surface of the first threaded rod 203. The second threaded rod 204 is fixedly mounted on one side surface of the limiting plate 206. The threads on the surfaces of the first threaded rod 203 and the second threaded rod 204 are set in opposite directions, that is, when the drive motor 201 rotates, it can drive the movable shaft 205 to run in opposite or opposite directions at the same time. The movable shaft 205 is sleeved on the surfaces of both the first threaded rod 203 and the second threaded rod 204. The movable shaft 205 has internal threads.

[0024] In a preferred embodiment, the motor shaft 202 is embedded in one side surface of the first guide disk 101, the drive motor 201 is located on one side of the first guide disk 101, and the first threaded rod 203 and the second threaded rod 204 are both located inside the connecting shaft 103.

[0025] In a preferred embodiment, the support structure 3 includes a connecting plate 301, a sliding rod 302, a pushing plate 303, and a support plate 304. The pushing plates 303 are movably connected to both sides of the support plate 304, and the connecting plates 301 are movably connected to the opposite sides of the pushing plates 303.

[0027] When the drive motor 201 is started, it drives the first threaded rod 203 and the second threaded rod 204 to rotate via the motor shaft 202, causing the movable shaft 205 to move in opposite directions. This causes the slide rod 302 to slide inside the slide groove 102, which in turn pushes the support plate 304 through the push plate 303. Under the action of the first rod 104, the second rod 106, and the spring 107, the support plate 304 is pushed out, thus fitting against the inner wall of the tire. When retracting, the drive motor 201 rotates in the opposite direction, causing the movable shaft 205 to move in the opposite direction, thereby allowing the support plate 304 to be retracted.
