Description

Technical Field

[0001] The utility model relates to the technical field of tire manufacturing and processing, in particular to a tire sidewall and exhaust line pressing device. Background Art

[0002] During the tire production process, the sidewall rubber component is mainly located from the shoulder to the bead of the tire, bearing the flexural deformation and protecting the steel cord of the tire body and the bead from damage. In the tire embryo molding process, the presence of bubbles in the sidewall is also a common problem. During the bonding process, the sidewall rubber will easily produce bubbles in the bead area when it is turned up. Among them, the bubbles remaining in the joint of the apex rubber component are the most difficult to remove. Therefore, effectively improving the problems of bubbles generated by the turn-up has become an important way to improve the performance of the bead area.

[0003] In order to solve the bubble problem, straight ridge exhaust lines are generally pressed on the sidewalls by means of pressure rollers. Although the addition of exhaust lines can significantly improve the situation of residual bubbles in the molding process, the bubbles are not easy to be discharged during the pressing process because some rubber parts are greatly affected by the shape of the parts during the bonding process. Although some bubbles can be removed by manual tire repair, the manpower loss is large, and the inconsistency of the quality of manual tire repair makes it difficult to guarantee the quality of the finished tire. For this reason, the utility model proposes a sidewall rubber exhaust puncture device. Utility Model Content

[0022] Example 1

[0023] Please refer to Figure 1-Figure 3 shown.

[0024] The utility model provides a tire sidewall and exhaust line pressing device, such as Figure 1 , Figure 2As shown, it includes a frame 2 installed on the transmission line 1, a pressure roller 6 is rotatably arranged inside the frame 2, and a plurality of ridges are arranged around the outer circumferential wall of the pressure roller 6; a driving assembly for driving the pressure roller 6 to rotate is arranged on the frame 2, and a reciprocating assembly for controlling the axial movement of the pressure roller 6 is arranged between the driving assembly and the pressure roller 6. The exhaust line pressing device provided in the present technical scheme mainly solves the problem that in the prior art, the straight ridge exhaust line is pressed on the tire sidewall by the pressure roller 6; although the residual bubbles in the molding process can be significantly improved after the exhaust line is added, the bubbles are not easily discharged during the lamination process because the shape of the parts is greatly affected during the lamination of some rubber parts. To improve the exhaust line pressing device, first, a frame 2 adapted to the transmission line 1 needs to be made, and then the frame 2 is installed on the frame of the transmission line 1 to ensure that the pressure roller 6 runs smoothly on the transmission line 1 under the drive of the driving motor 4, and the distance between the pressure roller 6 and the transmission line 1 can accommodate the passage of the rubber belt, and the pressure roller 6 can pass through the transmission line 1. When roller 6 is driven by driving motor 4 to continuously press the fitting surface of the rubber belt to form an exhaust line (groove), a driving force can be applied to the rubber belt through the ridges arranged on the surface of pressure roller 6, forcing the rubber belt to move along the transmission direction of transmission line 1 under the joint action of transmission line 1 and pressure roller 6, so as to continuously press the exhaust line for the rubber belt and improve the exhaust capacity of the subsequent rubber belt in the production process; and a reciprocating component for controlling the axial movement of pressure roller 6 is provided between the driving component and pressure roller 6, which can force pressure roller 6 and the ridges arranged on pressure roller 6 to move along the axial direction of pressure roller 6, thereby increasing the quality of the ridges pressing the rubber belt to produce the exhaust line.

[0025] In some technical solutions of the utility model, the driving assembly includes a mounting frame 3 mounted on the frame 2, a driving motor 4 is arranged on the mounting frame 3, and the output end of the driving motor 4 is drivingly connected to the rotating shaft of the pressing roller 6. The mounting frame 3 is bolted to the frame 2, and the driving motor 4 is fixed to the mounting frame 3 by bolts; the driving motor 4 is a servo motor, and its speed is adjustable, which can control the efficiency of the pressing roller 6 and the convex ridges arranged on the pressing roller 6 in making the exhaust line.

[0026] In some technical solutions of the present utility model, the reciprocating assembly includes a guide frame 9 rotatably arranged in the frame 2. The guide frame 9 is传动连接 with the output end of the driving motor 4. A displacement frame 7 is slidably arranged on the guide frame 9. A first push rod 10 connected to the displacement frame 7 is arranged on the guide frame 9. The displacement frame 7 is传动连接 with the rotating shaft of the pressure roller 6. One end of the pressure roller 6背离 the displacement frame 7 is provided with a shaft rod 14. The shaft rod 14穿设于 the frame 2 and extends outwards. The guide frame 9 is rotatably arranged in the mounting hole opened on the inner wall of the frame 2 through a load-bearing bearing. The guide frame 9 is传动连接 with the output end of the driving motor 4 through a coupling. The arranged first push rod 10 is an electric push rod. The electric push rod is电连接 with an external power supply through a conductive slip ring. When the telescopic end of the first push rod 10 extends out of the body of the first push rod 10, at this time, the displacement frame 7 will move on the guide frame 9 along the axis of the pressure roller 6, so that the convex ridges arranged on the pressure roller 6 move along the axis direction of the pressure roller 6. By reciprocating the above operations, the quality of the exhaust line made by pressing the rubber belt by the convex ridges is increased.

[0027] In some technical solutions of the present utility model, the displacement frame 7 is provided with a limiting groove. The guide frame 9 is provided with a limiting strip adapted to the limiting groove along the axial direction of the pressure roller 6. The arranged displacement frame 7 is in a "匚" shape. The limiting groove is a wedge-shaped limiting groove opened on the opposite side walls of the two horizontal sections of the guide frame 9. The limiting strip is adapted to the limiting groove and is wedge-shaped. In this way, the displacement frame 7 can be prevented from separating during the high-speed rotation process, which affects the normal operation of the equipment.

[0028] In some technical solutions of the present utility model, second push rods 5 are arranged at both ends of the frame 2. The bodies of the second push rods 5 are均与 the frame of the transmission line 1连接. The arranged second push rods 5 are pneumatic push rods. By setting the second push rods 5, the distance between the pressure roller 6 and the transmission line 1 can be controlled. Thus, when the pressure roller 6 presses the exhaust line on the rubber belt, a downward pressure along the vertical direction is施加 to the pressure roller 6, and the quality of the exhaust line made by pressing the rubber belt by the convex ridges is increased.

[0029] In some technical solutions of the present utility model, a sliding sleeve 11 is arranged on the frame 2沿竖直方向. A guide rod is arranged in the sliding sleeve 11. A brush strip 13 is arranged at the end of the guide rod靠近 the pressure roller 6.

[0030] In some technical solutions of the present utility model, the guide rod穿设于 the sliding sleeve 11. A limiting spring 15 connected to the sliding sleeve 11 is套设于 the guide rod.

[0031] In the frame 2, through the sliding sleeve 11, the guide rod and the limiting spring 15, the brush strip 13 arranged on the guide rod is used to清理 the rotating pressure roller 6 to avoid rubber strips or other impurities being夹杂 between any two adjacent convex ridges arranged on the pressure roller 6, and to avoid affecting the quality of the exhaust line made by the convex ridges on the rubber belt.

[0032] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
