Description

Technical Field

[0001] This utility model relates to the field of rubber tire molding technology, and in particular to a rubber tire molding and rolling device. Background Technology

[0002] Tires are circular, elastic rubber products that are mounted on various vehicles or machinery and roll on the ground. They are usually mounted on metal rims, support the vehicle body, buffer external impacts, make contact with the road surface, and ensure the vehicle's driving performance. Tires are often used under complex and harsh conditions. They are subjected to various deformations, loads, forces, and high and low temperatures during driving. Therefore, they must have high load-bearing capacity, traction capacity, and cushioning capacity. At the same time, they are also required to have high wear resistance and flexural strength, as well as low rolling resistance and heat generation.

[0003] In the tire production process, the tire blank needs to be placed on the forming drum, and the tire is formed by rolling a rubber pad on the forming drum. The tire rolling forming process requires processes such as shaping, tread pressing, wrapping, and sidewall pressing. However, the existing tire rolling forming equipment only completes the above processes on one forming drum. Because the forming time of a single tire is long, the tire forming processing efficiency is low. Utility Model Content

[0004] In order to overcome the above-mentioned defects in the prior art, the present invention provides a rubber tire forming and rolling device.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a rubber tire forming and rolling device, including a fixed frame, a turntable installed at the bottom of the fixed frame, two sets of forming drum assemblies symmetrically distributed around the center of the turntable axis on the side wall of the fixed frame, a drive shaft fixedly installed at the top of the fixed frame, a support frame provided above the fixed frame, and a drive motor for driving the fixed frame to rotate fixedly installed at the top of the support frame.

[0006] Furthermore, the forming drum assembly includes a spindle box and a forming drum. The spindle box is fixedly mounted on the end of the fixing frame, and the forming drum is rotatably mounted on the spindle box, extending toward the other end of the fixing frame.

[0007] Furthermore, the support frame includes a top beam that extends along the length of the fixed frame. Main support legs are fixedly installed on the front and rear sides of the end of the top beam. The main support legs have an "L" shaped structure and are reinforced at the bends.

[0008] Furthermore, a secondary support leg is fixedly installed on the side of the main support leg away from the top beam, and the bottom end of the secondary support leg is inclined away from the main support leg.

[0009] Furthermore, the drive shaft is rotatably mounted at the bottom center of the top beam, a top plate is fixedly mounted on the top of the top beam, a motor mounting bracket is fixedly mounted on the top plate, the drive motor is fixedly mounted on the motor mounting bracket, and the power output shaft of the drive motor extends downward and connects to the drive shaft.

[0010] Furthermore, support rods are fixedly installed at both the front and rear ends of the top plate, and the support rods are fixedly installed on the top of the main support leg.

[0011] Furthermore, the turntable includes a fixed base, a movable base is rotatably mounted on the top of the fixed base, the fixed frame is fixedly mounted on the top of the movable base, and the movable base is coaxially arranged with the drive shaft.

[0012] The beneficial effects of this utility model are that, through the design of two sets of forming drum assemblies symmetrically distributed around the center of the turntable axis on the side wall of the fixed frame, during production, the shaped tire blank moves to the front forming drum assembly for the tread pressing process. After the tread pressing process is completed, the drive motor drives the transmission shaft to rotate 180° in the forward direction, causing the front forming drum assembly to move to the rear for the reverse wrapping and sidewall pressing process. At this time, the front forming drum assembly performs the tread pressing process for a new set of tire blanks. This allows the tread pressing process, which has a longer production cycle, and the reverse wrapping and sidewall pressing process, which has a shorter production cycle, to be carried out simultaneously, thereby shortening the tire forming time and improving processing efficiency.

[0020] In this embodiment, the forming drum assembly includes a spindle box 4 and a forming drum 5. The spindle box 4 is fixedly installed at the end of the fixing frame 1, and the forming drum 5 is rotatably installed on the spindle box 4. The forming drum 5 extends toward the other end of the fixing frame 1. A geared motor and a transmission component are installed inside the spindle box 4. The transmission component, in conjunction with the geared motor, drives the forming drum 5 to rotate, so as to cooperate with the pressure roller to roll and form the tire blank on the forming drum 5.

[0021] In this embodiment, the support frame 6 includes a top beam 61, which extends along the length of the fixed frame 1. Main support legs 62 are fixedly installed on the front and rear sides of the end of the top beam 61. The main support legs 62 have an "L" shape structure. Reinforcing ribs 63 are provided at the bends of the main support legs 62 to improve the strength of the main support legs 62. A secondary support leg 64 is fixedly installed on the side of the main support leg 62 away from the top beam 61. The bottom end of the secondary support leg 64 is inclined away from the main support leg 62. The secondary support leg 64 cooperates with the main support leg 62 to support the top beam 61, thereby improving the stability of the main support frame 6 installation.

[0022] In this embodiment, the drive shaft 3 is rotatably mounted at the bottom center of the top beam 61. A top plate 7 is fixedly mounted on the top of the top beam 61. A motor mounting bracket 8 is fixedly mounted on the top plate 7. The drive motor 9 is fixedly mounted on the motor mounting bracket 8. The power output shaft of the drive motor 9 extends downward and connects to the drive shaft 3. Support rods 10 are fixedly mounted at both ends of the top plate 7.

The fixed seat 21 is fixedly mounted on the ground so that the fixed frame 1 is suspended in the air. The drive motor 9 drives the drive shaft 3 to rotate, causing the fixed frame 1 to rotate on the fixed seat 21.

[0023] In use, the shaped tire blank is moved to the front forming drum 5 via a tire blank conveying device for tread pressing. A pressure roller is located above the front forming drum, and the tire blank is rolled and shaped by the pressure roller in conjunction with the forming drum. The specific structure of the pressure roller is existing technology and will not be described in detail here. After the tread pressing process is completed, the drive motor rotates the transmission shaft 180° clockwise, moving the front forming drum 5 to the rear. A corresponding reverse wrapping and sidewall pressing device is installed on the rear of the device, which presses against the forming drum. 5. The reverse wrapping and sidewall pressing process is performed. The reverse wrapping and sidewall pressing device is existing technology and will not be described in detail here. At this time, the front forming drum 5 performs the tread pressing process of a new set of tire blanks. After the tread pressing process of the new set of tire blanks is completed, the drive motor drives the transmission shaft to rotate 180° in the opposite direction. The above steps are repeated to realize the continuous processing of the tire. This allows the tread pressing process, which has a longer production cycle, and the reverse wrapping and sidewall pressing process, which has a shorter production cycle, to be carried out simultaneously, thereby shortening the tire forming time and improving processing efficiency.
