Description

Technical Field

[0001] The utility model relates to the field of tire production equipment, in particular to a cap strip winding and pleating prevention device. Background Art

[0002] As we all know, the cap strip, as the skeleton material of the tire, plays an extremely important role in the tire structure, especially in terms of the high durability of the tire; the quality of the cap strip, the resulting pleating, jumping out and accumulation problems directly affect the intrinsic quality of the tire structure. During the production of the cap strip, the width limiting wheel is used to limit the position of the cap strip so that it can be rolled flat. Since there is a joint overlap in a roll of the cap strip, the joint area of ​​the cap strip will jump when passing through the limiting roller. Since there is no protective measure or device above the original limiting roller device, the cap strip jumps out of the limiting wheel and squeezes in the gap between the limiting wheel and the bracket, causing the cap strip to pleat, and at the same time causing the entire cutting and curling work to stagnate, affecting its curling tension, cutting quality, etc., increasing quality risks and cost waste. Summary of the invention

[0003] In order to overcome the deficiencies of the prior art, the utility model provides a crown band strip winding anti-pleating device to solve the problem of pleating caused by a joint jumping out of a limiting wheel when the crown band strip is wound.

[0004] The technical solution adopted by the utility model to solve its technical problems is: a crown strip winding and anti-pleating device, which is provided with a crown strip guiding device frame, and the crown strip reel is installed on the crown strip guiding device frame. It is characterized in that a bracket is fixed on the crown strip guiding device frame on the upper left side of the crown strip reel, and the left and right ends above the bracket are respectively installed with limiting rollers and pressure wheels via rotating shafts, and a U-shaped shielding card plate is sleeved on the limiting roller and connected to the bracket.

[0005] The beneficial effect of the utility model is that it can effectively prevent the crown band strip from jumping out of the limiting wheel, thereby solving the problem of crown band strip rolling and pleating. BRIEF DESCRIPTION OF THE DRAWINGS
