AI Technical Summary

Technical Problem

During tire manufacturing, the I-beams are prone to reverse rotation and wobbling during the unwinding process, causing the material roll to stick and fold inside, increasing production costs.

Method used

A device for preventing the reverse rotation of the I-beam wheel in a tire forming machine was designed. The device uses a guide car and a machine body guide frame, and installs an anti-reverse roller. The surface of the anti-reverse roller is covered with rubber and has a built-in one-way bearing, so that it can only rotate in one direction. The anti-reverse roller is driven by a guide rod cylinder to contact the I-beam wheel and prevent it from reversing.

Benefits of technology

It effectively prevents the H-beam rollers from reversing, prevents material rolls from sticking and folding inside, and reduces production costs.

Description

Technical Field

[0001] This utility model relates to the field of tire production equipment, and more specifically to an anti-reverse device for tire forming machines. Background Technology

[0002] As is well known, in the tire manufacturing process, I-beams are used to wind and transport semi-finished materials such as belt layers and padding. Due to inconsistent tension during the winding process, the material rolls are unevenly distributed on the I-beams. Furthermore, as the material rolls decrease during the unwinding process, the center of gravity of the I-beams and the material rolls changes continuously. Since the rotational inertia of the I-beams fully wound with material is large, the vehicle's brakes are insufficient to stop the rotation of the I-beams immediately. This causes the I-beams to reverse and wobble during the unwinding process, which in turn causes the material rolls to stick and fold inside, resulting in material rework or scrap, and increasing production costs. Summary of the Invention

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides an anti-reverse device for tire forming machines, which is used to eliminate the problem of material folding caused by the reverse rotation and shaking of the I-beam wheel during the opening process of the forming machine.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a device for preventing the reverse rotation of I-beam wheels for a tire forming machine, which is equipped with a guide car, a machine body guide frame is installed on the guide car, and I-beam wheels are set on the machine body guide frame. The feature is that the base is welded to the machine body guide frame, the guide rod cylinder is fixed to the upper surface of the base with bolts, the anti-reverse roller mounting seat is fixed to the cylinder rod end of the guide rod cylinder with bolts, a one-way bearing is installed inside the anti-reverse roller, the shaft passes through the one-way bearing and is fixed at both ends on the anti-reverse roller mounting seat, and a layer of rubber is attached to the surface of the anti-reverse roller.

[0005] The beneficial effect of this utility model is that the anti-reverse roller contacts the surface of the I-beam wheel. Since the anti-reverse roller can only rotate in one direction, it can prevent the I-beam wheel from reversing. Attached Figure Description

[0006] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0007] Figure 1 This is a schematic diagram of the structure of the present invention.

[0008] Figure 2 This is a schematic diagram of the anti-reverse device of this utility model.

[0009] In the diagram: 1. Guide car starter, 2. Machine body guide frame, 3. Anti-reverse device, 4. I-beam wheel, 5. Pad, 3-1. Base, 3-2. Guide rod cylinder, 3-3. Anti-reverse roller mounting seat, 3-4. Anti-reverse roller, 3-5. One-way bearing, 3-6. Shaft. Detailed Implementation

[0010] In the figure, this utility model includes a guide car 1, on which a body guide frame 2 is installed. I-beam wheels 4 are mounted on the body guide frame 2. A base 3-1 is welded to the body guide frame 2. A guide rod cylinder 3-2 is bolted to the upper surface of the base 3-1. An anti-reverse roller mounting seat 3-3 is bolted to the cylinder rod end of the guide rod cylinder 3-2. Two one-way bearings 3-5 are installed inside the anti-reverse roller 3-4. A shaft 3-6 passes through both ends of the two one-way bearings 3-5. Both ends of the shaft 3-6 pass through the ears on both sides of the anti-reverse roller mounting seat 3-3 and are fixed to the anti-reverse roller mounting seat 3-3. A layer of rubber is attached to the surface of the anti-reverse roller 3-4. The base 3-1, guide rod cylinder 3-2, anti-reverse roller mounting seat 3-3, anti-reverse roller 3-4, one-way bearings 3-5, and shaft 3-6 together constitute the anti-reverse device 3.

[0011] A layer of rubber is attached to the surface of the anti-reverse roller 3-4 to increase the coefficient of friction. A one-way bearing 3-5 is installed inside the anti-reverse roller 3-4, so that the anti-reverse roller 3-4 can only rotate in one direction. The guide rod cylinder 3-2 makes the anti-reverse roller 3-4 only move in a straight line and cannot rotate around the guide rod cylinder 3-2. The guide rod cylinder 2-2 extends and drives the anti-reverse roller 3-4 to contact the surface of the I-beam 4. Since the anti-reverse roller can only rotate in one direction, it can prevent the I-beam 4 from reversing.

[0012] When the equipment drives the pad 5, which in turn drives the I-beam wheel 4 to rotate, the guide rod cylinder 3-2 extends, causing the anti-reverse roller 3-4 to contact the I-beam wheel 4. The I-beam wheel 4 then drives the anti-reverse roller 3-4 to rotate in the guiding direction. When the power source for the equipment driving the pad 5 disappears, the I-beam wheel 4 and the internal material roll may reverse due to the shift in center of gravity. At this time, because the I-beam wheel 4 is in contact with the anti-reverse roller 3-4, the anti-reverse roller 3-4 cannot reverse, thus preventing the I-beam wheel 4 from reversing. When it is necessary to change the material, the guide rod cylinder 3-2 retracts, and the anti-reverse roller 3-4 disengages from the I-beam wheel 4, without affecting normal material changing.
