Embodiment Construction

[0036] In order to meet the growing demand for wide-tread tire production, improve the width accuracy of the cut parts, especially the angle accuracy, and increase productivity (14 times / min to 17 times / min), this invention proposes a new type of steel wire Cord cutting device and cutting process. Attached below Figure 1~9 The specific embodiment of the present invention will be further described in detail.

[0037] Such as Figure 1~9 The shown steel cord cutting device includes a cutting knife mechanism, a material pressing mechanism, a conveyor belt mechanism 9, a clamp fixing length mechanism, and a turning plate lifting mechanism.

[0038] The cutter mechanism includes an upper cutter mechanism and a lower cutter mechanism. Upper cutting mechanism such as figure 2 , 3 As shown, it includes an upper knife rest 12, an upper knife 1 installed on the upper knife rest 12, an upper knife driving mechanism, and an upper cutting knife anti-sticking mechanism 11. The upper kn...

Abstract

The invention discloses a wire cord fabric cutting-off device and a technology thereof. The cutting-off device comprises a cutting mechanism including an upper cutter and a lower cutter, a turning plate material lifting mechanism, a material pressing mechanism, a conveying belt mechanism and a clamp fixed length mechanism. The cutting mechanism including the upper cutter and the lower cutter comprises an upper cutter rack, the upper cutter mounted on the upper cutter rack, an upper cutter driving mechanism used for driving the upper cutter rack to move up and down, a rack body, a movable workbench, the lower cutter mounted on the movable workbench and an overall cutter adjusting mechanism. The turning plate material lifting mechanism comprises a turning plate and a turning plate linear driving mechanism. The clamp fixed length mechanism comprises a clamp support, a clamp mechanism, a longitudinal movement system and a transverse movement system. According to the wire cord fabric cutting-off device and the technology thereof, the turning plate material lifting mechanism and the material pressing mechanism clamp the wire cord fabric end and is lifted up from a lower cutter opening, the clamp fixed length mechanism clamps the wire cord fabric end for fixed-length and fixed-angle operation, the length and the angle of wide materials can be accurately determined, the materials tend not to be bonded on the upper cutter, the cut materials can accurately fall onto the conveying belt mechanism to be fed into a connector device, and thus the connector precision can be improved.

Description

technical field [0001] The invention relates to radial tire production equipment, in particular to a cutting device and a cutting process for cutting a carcass cord or a belt layer cord of a radial tire, and belongs to the field of rubber machinery. Background technique [0002] The carcass cord or belt layer cord of the existing radial tire needs to be rewound into a cord roll for use by a tire building machine after being cut, jointed, and wrapped in a cutting production line. With the development of radial tires and the requirements of wide tread and engineering radial tires, the width of cord strips (belt layer, splint fabric, carcass cord) gradually increases. [0003] The cutting device of the cutting production line is responsible for cutting the cord into fixed-length cord strips, and the conveyor belt receives the cut cord strips and sends them to the subsequent splicing device of the production line. In the prior art, the cord strips are delivered and fixed in le...
