Embodiment Construction

[0019] The spindle 2 used in the present invention, the four-roller calender, the coiling system 13, etc. are all commonly used equipment in the field, and the single fiber cord 1 used is a dipped nylon 66 cord with a specification of 1400dtex / 2. It is made of nylon 66 fiber filaments through twisting and dipping, and each cord is individually and continuously rolled onto a cylindrical paper tube to form a spindle 2, and the cords cannot have joints. The mixed rubber used is made of natural rubber, carbon black, accelerator, vulcanizing agent, anti-aging agent and other materials through internal mixer mixing and refining.

[0020] The spindle 2 is located in the spindle room, which has a temperature and humidity control system, the temperature is at least 3°C ​​higher than the ambient temperature outside the spindle room, and the humidity is ≤50%. In the spindle room, 1400 spindles 2 are installed on both sides of the spindle frame 3, 700 spindles on each side, and the spindl...

Abstract

The invention relates to a rubber coating fiber cord fabric manufacturing method for conducting rubber coating through a calender and belongs to the field of tire production. Single guided-open fibercord threads penetrate through small thread arranging windows at the front end of a spindle frame correspondingly, then are gathered, penetrate through a total thread arranging window and penetrate through two guide rollers horizontally. The cord threads are arranged evenly in parallel through a warp arranging roller and enter a gap between a second roller and a third roller of the four-roller calender evenly in parallel through a pressure roller. A mixed rubber sheet obtained through calendering by a first roller and a second roller of the four-roller calender wraps the second roller, a mixedrubber sheet obtained through calendering by the fourth roller and the third roller wraps the third roller, the mixed sheets wrapping the second roller and the third roller conduct calendering rubbercoating on all the single fiber cord threads arranged in parallel in the gap, and rubber coating fiber cord fabric is formed. The rubber coating fiber cord fabric is pulled and cooled by a pulling cooling system and enters a storage system, and the rubber coating fiber cord fabric coming out of the storage system enters a rolling system through a conveying belt to be rolled by a cushion cloth.

Description

technical field [0001] The invention relates to the field of tire production, in particular to a method for manufacturing rubber-coated fiber cords covered with rubber by a calender. Background technique [0002] As we all know, rubber-covered fiber cord refers to the semi-finished products used to manufacture rubber products such as tires and conveyor belts. It is made of fiber cords covered with rubber compound, and has a certain thickness, width and cord density. The compounded rubber refers to the mixing and refining of natural rubber or synthetic rubber and reinforcing materials, such as carbon black, white carbon black, vulcanizing agent, vulcanization accelerator, anti-aging agent and other raw materials with internal mixer and other rubber mixing equipment. into a mixture with good ductility. The existing manufacturing methods of tire rubber-coated fiber cord include: 1. The equipment adopts a four-roller calender; 2. The material adopts fiber cord fabric with weft ...
