Problems solved by technology
However, the 90° fiber cord cutting machine currently used in China has the following problems: the speed of the lapping device is relatively slow, it can only lap about 8 times per minute, and the positioning accuracy is poor, so not only the production efficiency is low, but also the quality of the product is difficult. Guarantee, so this kind of equipment will undoubtedly not be able to meet the production quality and increasing output requirements of passenger tires

The invention relates to a lapping device of a 90-degree fibre cord fabric cutter, comprising a base, a stand, a plurality of lapping cylinders, a pressure plate and a plurality of bearing plates. Twosides of the base are fixed on the stand of an output device; the stand is mounted above the base; the bearing plates are arranged in parallel below the middle part of the stand at spaced intervals,and each bearing plate is located between the gaps of two straps on the output device; the lapping cylinders are mounted at the upper part of the stand at spaced intervals, and the tail end of a piston rod of each lapping cylinder is connected at the backside of the pressure plate; and the rear parts of two ends of the pressure plate are hinged at two sides in the middle of the stand. The lappingdevice can be acted simultaneously together with a cloth puller and a fabrie joining device and matched organically, thereby improving the production efficiency by 2.5 times than the prior art, i.e. 20 times of cutting and lapping can be performed per minute. The positioning precision is high so that the quality and the production efficiency of the product are improved. In addition, the lapping device is arranged on the output device, thereby having reasonable structural design and reducing the occupying area.
Description
technical field [0001] The invention belongs to the technical field of rubber tire machinery, in particular to a lapping device of a 90° fiber cord cutting machine. Background technique [0002] In recent years, with the rapid development of small cars, the amount of passenger tires (radial semi-steel tires) used by small cars has also increased dramatically. Carcass cords are required for passenger tire molding. The process of making carcass cords is to cut the rolls of calendered fiber cords along the transverse direction according to the process specifications by the 90° fiber cord cutting machine, one of the main equipment for making passenger tires. Form rectangular fiber ply pieces, then overlap the non-cut edge parts of adjacent fiber ply pieces in turn, and finally wind them into rolls for use in the next process. However, the 90° fiber cord cutting machine currently used in China has the following problems: the speed of the lapping device is relatively slow, it can...
