AI Technical Summary
When the crown strip is wound at high speed during tire production, it may suddenly stop and detach from the roller, causing the bonding position to shift, which affects tire quality and production costs.
Two axially parallel guide rollers are arranged in the horizontal direction, and a first positioning roller, a second positioning roller, and a third positioning roller are vertically installed between them. A U-shaped anti-detachment roller device is installed on the periphery to prevent the crown strip from detaching from the positioning rollers.
It effectively prevents the crown strip from detaching from the positioning roller, ensures accurate winding position, improves tire production quality, and avoids potential quality problems.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to the field of tire production, and concretely relates to a device for preventing crown strip from separating from the roller in the tire production process, and is especially suitable for the anti-separation roller device of crown strip in the high-speed winding process. BACKGROUND
[0002] It is known that crown strip, as the framework material of tire, plays a crucial role in the tire structure, especially in the high-speed durability of tire. The bonding quality of crown strip directly affects the inherent quality of tire. However, in the prior art, crown strip is easy to separate from the roller when the storage ring is guided to the tail during the high-speed winding process, which leads to the deviation of the bonding position and further affects the quality and performance of tire.
[0003] In the prior art, crown strip is wound at a speed of 5 meters per second, and when the storage ring is guided to the tail, crown strip will suddenly stop, which leads to its separation from the roller. When bonding again, the position of crown strip will deviate, which increases the quality risk and production cost. Therefore, there is an urgent need for a device that can effectively prevent crown strip from separating from the roller to ensure the bonding quality of crown strip. SUMMARY
[0004] In order to overcome the shortcomings of the prior art, the utility model provides a crown strip anti-separation roller device to solve the problem that crown strip separates from the roller due to sudden stop during the high-speed winding process in the prior art, avoid the deviation of the bonding position of crown strip, and thus improve the production quality and performance of tire.
[0005] The utility model solves the technical scheme that a crown strip anti-separation roller device is provided with two axially parallel guide rollers in the horizontal direction, characterized in that a first positioning roller, a second positioning roller and a third positioning roller are vertically installed between the two guide rollers, the end of the first positioning roller, the second positioning roller and the third positioning roller is fixed on the roller fixing frame, the first positioning roller is located on one side of the intermediate part of the second positioning roller and the third positioning roller, a U-shaped anti-separation roller device is installed around the first positioning roller, the second positioning roller and the third positioning roller, and the opening part of the U-shaped anti-separation roller device is located on one side of the second positioning roller and the third positioning roller.
[0006] The utility model has the beneficial effects that crown strip is prevented from completely separating from the positioning roller, the deviation of the bonding position of crown strip is effectively avoided, the position of crown strip will not deviate during the next winding, the winding quality of crown strip is ensured, and the quality risk and cost waste in tire production are avoided. BRIEF DESCRIPTION OF DRAWINGS
[0007] The utility model will be further described below in combination with the drawings and examples.
[0008] Figure 1 The structure schematic view of the utility model.
[0009] Figure 2 The utility model is the top view.
[0010] In the drawing, 1. anti-falling roller device, 2. roller fixed frame, 3. guide roller, 4. first positioning roller, 5. second positioning roller, 6. third positioning roller, 7. crown tape, 8. crown tape self-weight falling direction. DETAILED DESCRIPTION
[0011] In the drawing, the utility model is provided with two axial parallel guide rollers 3 in horizontal direction, and the first positioning roller 4, the second positioning roller 5 and the third positioning roller 6 are vertically installed between the two guide rollers 3, the end of the first positioning roller 4, the second positioning roller 5 and the third positioning roller 6 is fixed on the roller fixed frame 2, the first positioning roller 4 is located at one side of the intermediate position between the second positioning roller 5 and the third positioning roller 6, the U-shaped anti-falling roller device 1 is installed on the periphery of the first positioning roller 4, the second positioning roller 5 and the third positioning roller 6, and the opening part of the U-shaped anti-falling roller device 1 is located at one side of the second positioning roller 5 and the third positioning roller 6.
[0012] When the utility model is produced, the crown tape 7 enters the first positioning roller 4, the second positioning roller 5 and the third positioning roller 6 from the guide roller 3, and the crown tape 7 passes from the rear of the first positioning roller 4 and the front of the second positioning roller 5 and the third positioning roller; the crown tape 7 will not fall due to being straightened by tension in normal production, but when winding is finished, the crown tape 7 will fall due to self-weight in the crown tape self-weight falling direction 8, and the crown tape 7 will fall out of the first positioning roller 4, the second positioning roller 5 and the third positioning roller 6, and the position of the crown tape 7 changes due to the falling of the crown tape 7 in the next round of winding, resulting in the problem of incorrect position of the crown tape 7 winding. After the anti-falling device 1 is added, the crown tape 7 will be blocked by the anti-falling device 1 after falling, and the crown tape 7 will not fall out of the first positioning roller 4, the second positioning roller 5 and the third positioning roller 6 as a whole, so the problem of incorrect position of the crown tape winding will not occur.
