Description

Technical Field

[0001] The utility model relates to the field of tire production, and particularly relates to a positioning edge stop device for a zero-degree material feeding rack. Background Art

[0002] Zero-degree materials are one of the indispensable material components in tire production. Zero-degree materials have different widths and specifications, and at the same time, the fitting and positioning of zero-degree materials will be set according to the shape of the tire design. Therefore, when changing tires with different zero-degree specifications, it is necessary to adjust the positioning edge stop of the zero-degree feeding rack, and the adjustment frequency is relatively high. The existing zero-degree feeding rack edge stop adjustment device is time-consuming and laborious to adjust. At the same time, it is difficult to adjust the zero-degree positioning to the required position at one time. If the positioning is inaccurate, it is easy to squeeze the positioning of the remaining belted treads, resulting in batch unqualified tire products.

[0003] In the prior art, the zero-degree feeding rack is in the form of a flap pushed by a cylinder. There are pressure rollers and edge stops on the upper part of the flap. The edge stops are fixed by a large number of screws, which is time-consuming and laborious to adjust. The present invention removes the complex mechanism and uses a shaft with bearings to replace the original edge stop, and the handle controls the tightness of the shaft and the locking block (threaded connection) clamping the chute plate to achieve quick positioning replacement.

[0004] Please refer to Figure 1 , in the prior art, the zero-degree feeding rack is in the form of a flap pushed by a cylinder. There are 2 groups of pressure rollers and edge stops on the upper part of the flap. When changing the positioning, it is necessary to move the position of the pressure rollers. There are two fastening screws on the pressure rollers that need to be adjusted by professional technicians using special tools; when changing zero-degree materials with different widths, it is necessary to move the position of the edge stops. There are two fastening screws on the edge stops that need to be adjusted by professional technicians using special tools; therefore, when normally changing the zero-degree specifications, 4 components and 8 screws need to be adjusted at one time. It is often difficult to adjust them well at one time and requires repeated adjustment 2-3 times, which is time-consuming and laborious. Over the years, the screw parts of this component have become slippery and difficult to lock for precise positioning. The purpose of the present invention is to reduce the adjustment difficulty so that ordinary personnel can adjust it without professional technicians using special tools, reduce the adjustment time and simplify the mechanism, reduce the inefficiency of the mechanism caused by changing specifications, and enhance the reliability of the mechanism.

[0024] The utility model controls the rotation of the rotating shaft through the handle to realize the locking and loosening of the positioning component. The operation is simple, and there is no need for professional technicians to use special tools. Ordinary personnel can carry out the adjustment. The positioning component can move freely along the chute, quickly adjusting the position. When the predetermined position is reached, it is fixed by the locking component to achieve quick and accurate positioning. The utility model abandons the complex mechanism design, adopts the design of a bearing on the shaft, simplifies the structure of the whole device, reduces the failure points, and improves the reliability of the device. Due to the simple and fast adjustment process, it reduces the mistakes and damages caused by frequent adjustment, improves the production efficiency, and reduces the failure rate caused by specification replacement. By accurately positioning the zero-degree material, it avoids the material extrusion and dislocation caused by inaccurate positioning, ensures the quality consistency of tire products, and reduces the production of unqualified products.

[0025] The working process of the zero-degree material feeding rack positioning retaining edge device of the present utility model is as follows:

[0026] 1. Initial state: In the initial state, all positioning components are in the locked state, that is, the rotating shaft of each positioning component is firmly connected to the chute plate through a nut, so that the positioning component is fixed at a specific position on the chute plate, forming a retaining edge for the zero-degree material.

[0027] 2. Unlock the positioning component: When it is necessary to adjust the position of the positioning component, by manually operating the handle 7 and rotating the handle counterclockwise, the thread between the rotating shaft 9 and the locking component (nut) is loosened, gradually releasing the locked state of the positioning component. At this time, the positioning component is in an active state and can move freely in the strip-shaped groove of the chute plate 14.

[0028] 3. Adjust the device: When the positioning component is in an active state, according to the specifications and position requirements of the zero-degree material, manually move the positioning component so that it moves along the strip-shaped groove of the chute plate 14 to the required position. During the movement process, the sliding part is kept in sliding connection with the strip-shaped groove, and the bearing is sleeved outside the rotating shaft, reducing friction and making the movement process smoother.

[0029] 4. Locking and positioning assembly:

[0030] After the positioning assembly moves to the predetermined position, by rotating the handle 7 clockwise, the thread between the rotating shaft 9 and the locking member (nut) is gradually tightened until the positioning assembly is firmly locked on the chute plate 14. At this time, the positioning assembly is in the locked state, forming a new zero-degree material baffle position.

[0031] 5. Repeated adjustment: According to the actual production needs, if it is necessary to adjust the positions of other positioning assemblies, repeat the above steps to unlock, move, and lock all the positioning assemblies that need to be adjusted in turn until all the positioning assemblies are adjusted to the appropriate positions.

[0032] 6. Normal operation: After all the positioning assemblies are adjusted and locked, the zero-degree material feeding rack can operate normally. The zero-degree material is smoothly transported through the rollers behind the chute plate 14, and the baffle formed by the positioning assembly ensures the accurate positioning of the material, guaranteeing the stability and consistency of the zero-degree material during the production process.

[0033] 7. Maintenance and repair: During long-term use, if maintenance or repair is required, the positioning assembly can be unlocked through the handle 7 for necessary adjustment or replacement. Since the structure of the present utility model is simple, it is easy to disassemble, assemble, and maintain, reducing the maintenance time and cost.

[0034] By controlling the tightness of the thread between the rotating shaft 9 and the locking member (nut) through the handle 7, the locking and moving states of the positioning assembly are switched, enabling the positioning assembly to move freely and be accurately positioned in the strip-shaped groove of the chute plate 14. The present utility model not only has simple operation and rapid adjustment, but also has a simplified structure and reduced failure rate, significantly improving the production efficiency and product quality.
