Collecting type 90-degree steel wire cord fabric cutting machine and control method thereof

Abstract

The invention discloses a collecting type 90-degree steel wire cord fabric cutting machine. The collecting type 90-degree steel wire cord fabric cutting machine comprises an unwinding device, an input device, a cutting device, a fabric pulling device, a fabric collecting device, a splicing device, an output device and a winding device, wherein the input device comprises a plurality of unpowered rollers; the cutting device and the fabric pulling device are sequentially arranged in front of the input device; the fabric pulling device comprises a row of clamps in parallel to the unpowered rollers, a fabric pulling motor capable of driving the clamps to move forwards and backwards, and a screw nut mechanism for transmission; the fabric collecting device comprises a conveying belt which is inclined downwards along the feeding direction and a supporting beam which is arranged in the middle of the conveying belt; the supporting beam can be driven to be lifted so as to support the conveying belt at the front section for material collection. Meanwhile, the invention discloses a control method of the collecting type 90-degree steel wire cord fabric cutting machine. Due to the integrated design of fabric pulling and unwinding, a set of servo and control systems is simplified, and the cost is reduced; meanwhile, the efficiency is greatly improved from 8 times per minute to 16 times per minute, and the splicing and edge-aligning accuracy is improved by aligning an edge-checking roller on the side of the conveying belt with the output device.

Description

technical field [0001] The invention relates to the technical field of rubber tire machinery, in particular to a high-efficiency access-type 90° steel cord cutting machine with a simple structure and a small footprint and a control method thereof. Background technique [0002] The carcass cord is the main skeleton component of the tire, and the equipment for making the carcass cord is one of the main equipment in the tire manufacturing process. The 90° steel cord cutting machine cuts the rolled rolled steel cord into rectangular steel cord pieces in the transverse direction according to the process specifications, and then splices the non-cut edge parts of adjacent steel cord pieces together, and finally winds them into rolls. For the next tire building process. However, the 90° steel cord cutting machine currently used in China has the following problems: [0003] 1. The cutting machine has two types of fixed-length feeding disc knife type and guillotine knife. The disadv...

AI Technical Summary

Problems solved by technology

[0003] 1. The cutting machine has two types of fixed-length feeding disc knife type and guillotine knife. The disadvantage is that the speed of cutting itself is small, the equipment composition is relatively complicated, and the quality of the joints is not easy to control.

Disadvantage 2. The feeding speed is greater than 50 m / min. The relative movement between the conveyor belt and the cord affects the cutting width, and the greater the speed, the greater the error. Especially for thinner steel cords, the cutting length accuracy is ±2mm, and the production efficiency is at most only 8 knives per minute, unable to meet the quality requirements of the product (cutting width tolerance ≤ ± 0.5mm, stitching misalignment tolerance ≤ ± 0.5mm)

[0004] 2. Vacuum suction cup is used for cloth connection, the speed of this device is relatively slow, and the positioning accuracy is poor

[0005] 3. The speed of the splicing device is relatively slow, it can only overlap 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 to guarantee, so this kind of equipment will undoubtedly not meet the tire production quality and the increasing Increased production requirements

[0006] 4. The compatibility between the loading and unloading trolley and the cutting machine is poor, and it takes a long time to affect the efficiency of the whole machine

[0007] 5. The receiving place also needs to replace the trolley after it is wound into a roll, which also takes up time and affects efficiency

[0008] 6. The whole machine has many cloth covers, occupies a large area, has a complex structure, high production cost and use cost, and difficult operation and maintenance
