Abstract

The invention relates to aluminum processing equipment, in particular to a scroll pressure compensation method for aluminum foil slitting and bundling equipment, which is used in a double-zero aluminum slitting and bundling equipment control system. The method comprises the following steps: controlling the coiling process of the aluminum foil slitting and bundling equipment equipped with a scroll, an ironing roll and a support roll by a computer, wherein the ironing roll downwards presses the scroll and an aluminum foil material coil, and the support roll upwards supports the scroll and the aluminum foil material coil; and when the aluminum foil is coiled by the scroll, applying upward working pressure P on the support roll, wherein the pressure P is the sum of reference pressure P0, coil weight compensation pressure P1 and velocity compensation pressure P2.

Description

Aluminium foil is cut the scroll pressure compensation method of bundling equipment

Technical field

The present invention relates to aluminium Fabricating machinery, specifically a kind of aluminium foil of cutting bundling apparatus control system for double-zero aluminum foil is cut the scroll pressure compensation method of bundling equipment.

Background technology

In aluminium foil processing, aluminium sheet, through the rolling of cold rolling machine, aluminium foil blooming mill, finish foil mill, forms the aluminium foil of double-deck 0.03-0.006mm.By foil separator double-deck aluminium foil separately, require aluminium foil wide 800-1720mm to cut into according to different business some, the aluminium foil of different in width simultaneously, and be rolled into aluminium and roll up.In presentation quality, require to cut aluminium foil surface cleaning, smooth, cut aluminum foil coil face and end face and should tightly wrap together, end face is smooth.Do not allow turriform, staggered floor, pine layer or tube core free dropping phenomenon, be all less than 1 millimeter around cut roll surface evenness male and fomale(M&F).Because aluminium foil bundling is that aluminium foil is produced important subsequent process, the quality on aluminium foil and yield rate have important impact, so foil separator is the gordian technique equipment of modern aluminum processing.

The shafting structure of existing aluminium foil bundling equipment as shown in Figure 1, generally includes a spool 1 that is used for batching aluminium foil, and a rubber roll is set above spool, is called ironing roll 2, plays the effect that flattens band; A rubber roll is set below spool and is called backing roll 3, not only played spreading, and the more important thing is whole spool, the effect of coil weight supported of playing.

In the time cutting the operation of bundling equipment, start production status with certain speed, that people operates owing to cutting when operation equipment running velocity, the speed that raises speed when operation is cut impact the planeness of rear aluminium foil end face, therefore while cutting operation, adopt speed-raising operation fast, within the utmost point short time, approximately within several seconds, reach the F-Zero setting.Like this can be by bottoming THICKNESS CONTROL in 5mm, to improve conforming product rate.Along with the weight on the increasing spool of coil diameter also can be more and more heavier, take-up reel just there will be buckling phenomenon, just can not tightly press against the surface of band, in this simultaneously in high-speed production in the situation that tension force just there will be larger variation, and the large place of tension force there will be alice phenomenon, the place that tension force is little there will be too pine of rewinding body, the irregular race of rolling limit phenomenon.These situations have all directly affected final product design.

For fear of the problems referred to above, conventionally in coiling process, backing roll is applied extra charging pressure and finally acts on spool, the distortion producing to compensate spool.But because the impact that the heavy combined action countershaft of rotating speed and volume produces is very complicated, be difficult to by the model of conventional calculating build-up pressure compensation, and it is applied to control and the adjustment of pressure, therefore current actual production relies on site operation personnel's operating experience to carry out manually operated pressure compensation mostly, be difficult to reach preferably pressure compensation effect, restrict the raising of product design, also affected production efficiency.

Summary of the invention

Technical matters to be solved by this invention is, provides one to be applied to aluminium foil and cuts bundling equipment, and the aluminium foil that can improve aluminum foil coiling quality and production efficiency is cut the scroll pressure compensation method of bundling equipment.

The scroll pressure compensation method that aluminium foil of the present invention is cut bundling equipment is: the coiling process of being cut bundling equipment by computing machine to having the aluminium foil of spool, ironing roll and backing roll is controlled, the downward pressured spool of ironing roll and aluminium foil material volume, backing roll is supporting reel and aluminium foil material volume upwards; The bundling overall width of aluminium foil material volume is 800～1720mm, and the maximum coil diameter of bundling is 75～600mm; Batch in aluminium foil process backing roll is applied to an operation pressure P upwards at spool, the size of described pressure P is base pressure P ₀, the heavy charging pressure P of volume ₁and velocity compensation pressure P ₂this three's sum;

Described base pressure P ₀value be applied to positive pressure, backing roll on spool this few part sums of conducting oneself with dignity by spool deadweight, ironing roll deadweight, ironing roll and determine;

The heavy charging pressure P of described volume ₁value obtain by the following method: when the actual volume on spool be heavily less than maximum volume-weight 15% time P ₁value is 0; When the actual volume on spool heavy from 15% during to 20% variation of maximum volume-weight, P ₁value is from base pressure P ₀7% to 10% linear change; When the actual volume on spool heavy from 20% during to 25% variation of maximum volume-weight, P ₁value is from base pressure P ₀10% to 13% linear change; When the actual volume on spool heavy from 25% during to 30% variation of maximum volume-weight, P ₁value is from base pressure P ₀13% to 20% linear change; When the actual volume on spool heavy from 30% during to 40% variation of maximum volume-weight, P ₁value is from base pressure P ₀20% to 35% linear change; When the actual volume on spool heavy from 40% during to 50% variation of maximum volume-weight, P ₁value is from base pressure P ₀35% to 60% linear change; When the actual volume on spool heavy from 50% during to 70% variation of maximum volume-weight, P ₁value is from base pressure P ₀60% to 90% linear change; When the actual volume on spool heavy from 70% during to 80% variation of maximum volume-weight, P ₁value is from base pressure P ₀90% to 100% linear change; When the actual volume on spool heavy from 80% during to 100% variation of maximum volume-weight, P ₁value is base pressure P ₀100%; Described maximum volume-weight calculates and obtains according to the actual bundling overall width of aluminium foil material volume, the maximum coil diameter of actual bundling and density of material;
