Guide roller of vertical aluminum foil slitter and production method thereof

Abstract

The invention provides a guide roller of a vertical aluminum foil slitter. The guide roller comprises a roller body and a spindle head, wherein the roller body is of a hollow cylindrical structure made of a carbon fiber material; and the spindle head is embedded into the two ends of the roller body. The invention also provides a production method of the guide roller. The production method comprises the steps of: uniformly winding PAN-based carbon fiber cloth on a mould, enabling the mould to be in a vacuum furnace in a fixed manner so as to manufacture the PAN-based carbon fiber cloth to be a roller body, wherein the absolute pressure in the vacuum furnace is less than or equal to 50pa, curing the roller body at the temperature of 120 DEG C-140 DEG C, taking out the roller body from the furnace, dismantling the mould, then embedding the manufactured spindle head into the two ends of the roller body for fixing, and grinding the roller body by using a grinding wheel so as to achieve the using accuracy. As the carbon fiber has high strength and light weight, the linear speed (both the raising speed and the reducing speed) of a driven guide roller can be consistent with the linear speed of a belt material, so that the quality requirements of products can be ensured. Simultaneously, as the carbon fiber has excellent modulus of elasticity and creep resistance as well as good toughness, the guide roller has very low vibration under the condition of ensuring the machining accuracy, the production speed is greatly increased and the production efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the field of aluminum foil slitting equipment, and in particular relates to a guide roller of an aluminum foil vertical slitting machine and a production method thereof. Background technique [0002] The transmission mode of the middle guide roller of aluminum foil vertical slitting machine has two kinds: belt drive guide roller and driven guide roller. The following problems exist in the production process of rollers: [0003] When the aluminum foil slitting machine is started and the speed is increased (the linear speed reaches the normal working speed of 200-500m / min within 3-5 seconds), since the driven guide roller completely depends on the angle formed by the strip and the guide roller, Relying on the front and rear tension to tighten the strip, the coiling device drives the strip to drag the driven guide roller to rotate. Due to the heavy weight of the steel core guide roller, the heaviest guide roller reaches 180 kg, a...

Problems solved by technology

[0003] When the aluminum foil slitting machine is started and the speed is increased (the linear speed reaches the normal working speed of 200-500m / min within 3-5 seconds), since the driven guide roller completely depends on the angle formed by the strip and the guide roller, Relying on the front and rear tension to tighten the strip, the coiling device drives the strip to drag the driven guide roller to rotate. Due to the heavy weight of the steel core guide roller, the heaviest guide roller reaches 180 kg, and the speed of the guide roller increases slowly. The linear speed of the strip cannot be reached within a short period of time, especially when producing strips with a thickness below 0.009mm. Due to the small tension used, the speed increase is even slower. Because the line speed cannot be synchronized, serious scratches appear on the surface of the strip. Injuries seriously affect product quality; when the equipment stops and slows down, due to the large inertia of the guide rollers, the linear speed of the guide rollers exceeds the linear speed of the strip, scratches will also occur, and the quality requirements cannot be met.

[0004] The production speed of the aluminum foil slitting machine, the steel guide roller is heavy due to its own weight, the faster the speed, the vibration of the guide roller will increase accordingly, and the product quality cannot be guaranteed. Generally, the production line speed of products with a thickness of 0.009mm and above is maintained at 200-500m / Min, the production line speed of products with a thickness below 0.009mm is kept between 100-300m / min, the production speed cannot be increased, which seriously restricts the production efficiency
