In addition, the photoelectric switch is arranged on a take-up side, breakage of the foil can be quickly detected, a foil cut-off tool is disposed on a take-off side, aluminum foils can be quickly cut off on the take-off side, accordingly, and the foils on the take-off side stop being accumulated at a roll and are driven to retract along backward tension.

Description

A kind of foil mill broken belt checkout gear
Technical field
The utility model relates to paper tinsel and rolls technical field, relates in particular to a kind of foil mill broken belt checkout gear.
Background technology
At present, the used rolling main body of oil of aluminium foil mill is the low-flash kerosene raffinate of narrow fraction (saturated hydrocarbons), and it is formulated to add a spot of high molecular alcohol, ester or aliphatic acid, and flash-point is about about 75-120 ℃.For enhancing productivity, in the operation of rolling, the aluminium foil linear velocity is up to 600-1300m/min, and the ROLLING OIL of high-speed motion impinges upon on equipment or the foil, then can form a large amount of tiny oil droplets and mist of oil.Mill speed is high more, easy more formation high-temperature oil mist.
The aluminum foil finished product passage adopts no roll gap pressure pattern rolling, and roll one side is for batching drive system, and opposite side is the uncoiling drive system, and aluminium foil is tightened under the front and back tension force that two cover drive systems provide, and to batching the drive system lateral movement.After static that external condition (like broken belt) produces or frictional heat acquire a certain degree, cause the condition of a fire easily.Reason maybe be as follows: 1, foil tension force is big, behind the broken belt foil collide at a high speed and with equipment friction, local temperature rising initiation fire; 2, broken belt moment, the static that accumulates on the foil is at the plane of disruption point discharge mist of oil that ignites.And broken belt possibly be that paper tinsel rolls the common multiple accident in the process because paper tinsel rolls multiple reasons such as coiling tension in the process is unstable, the control of plate shape is improper, the milling train operation is unskilled and causes.
Behind the broken belt, not only be prone to initiation fire, bring potential safety hazard; Also can amass by the plug stockpile, waste raw material, and destroy roller surface quality, influence the output and the quality of aluminium foil, can also cause active to pass a universal coupling screw distortion when serious and twist off, damage the equipment of several hundred million units at the roll gap place.Therefore, when broken belt takes place, in the shortest time, starting disconnected paper tinsel cutter will stop the accumulation of foil and stretching of the intensity of a fire still to the aluminium foil cut-out of roll place high-speed motion, be the effective way that reduces production loss.
Must receive the broken belt detection signal earlier before starting disconnected paper tinsel cutter.Existing broken belt detection signal process of transmitting is following: 1, current of electric speed sampling; 2, calculate the tension force speed of roll front and back foil; 3, send result of calculation to controller; 4, controller compares computing with result of calculation and preset value; Output broken belt protector signal when 5, reaching preset value drives disconnected paper tinsel cutter and cuts off aluminium foil.Broken belt protector signal triggering link is many, also needs through twice computing, and the reaction time reaches the several seconds.
The utility model content
The utility model embodiment provides a kind of fast detecting broken belt, in time feeds back the foil mill broken belt checkout gear of broken belt protector signal.
For realizing above-mentioned purpose, the utility model embodiment provides following technical scheme:
A kind of foil mill broken belt checkout gear, said checkout gear comprise that one is arranged on the optoelectronic switch that batches the drive system side, and the disconnected paper tinsel cutter control device of a reception photoelectric switching signal.
Preferably, said optoelectronic switch is any one in correlation type, diffuse reflection type, minute surface reflection-type, slot type, the optical fiber type.
Preferably, said disconnected paper tinsel cutter control device connects disconnected paper tinsel cutter, and said disconnected paper tinsel cutter is arranged on uncoiling drive system side.
Compared with prior art, the utlity model has following beneficial effect:
1, fast detecting broken belt: a, adopt optoelectronic switch to detect the continuation degree of foil, in case broken belt occurs, optoelectronic switch moment just can be sent the signal of telecommunication according to the variation of luminous intensity, need not the calculating and the contrast of complicacy, improves reaction speed greatly; B, with optoelectronic switch be arranged on pulling force bigger batch the drive system side because behind the broken belt, the aluminium foil line of motion speed of batching side is greater than the uncoiling side, therefore can detect broken belt quickly batching side, further improves detection speed;
2, in time stop and pile up: optoelectronic switch is arranged on and batches side and comparatively fast detect broken belt; The paper tinsel cutter that will break is arranged on the uncoiling side, cuts off uncoiling side aluminium foil rapidly, makes uncoiling side foil stop piling up to the roll place; And make foil along backward tension force retraction; Away from the broken belt place, avoid wastage of material, eliminate condition of a fire hidden danger.
The utility model foil mill broken belt checkout gear foreshortens to the time that broken belt occurs to disconnected paper tinsel cutter cut-out foil in 500 milliseconds, is much better than the several seconds of the prior art.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art; To do to introduce simply to the accompanying drawing of required use among the embodiment below; Obviously, the accompanying drawing in describing below only is some embodiment of the utility model, for those of ordinary skills; Under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the schematic flow sheet of the utility model embodiment one;
1, roll, 2, the uncoiling drive system, 3, batch drive system, 4, foil, 5, optoelectronic switch, 6, disconnected paper tinsel cutter, 7, disconnected paper tinsel cutter control device.
The specific embodiment
To combine the accompanying drawing among the utility model embodiment below, the technical scheme among the utility model embodiment is carried out clear, intactly description, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
Optoelectronic switch (photoelectric sensor) is the abbreviation of photoelectricity near switch, utilizes detected material to the blocking or reflect of light beam, and by the synchronization loop gating circuit, thereby inspected object has or not.Optoelectronic switch converts input current into optical signal and penetrates on transmitter, receiver is again according to the strong and weak of the light that receives or there is unmatchful target object to survey.Its employed cold light source has infrared light, red light, green light and blue light etc., but noncontact, the rapidly state and the action of materials such as the various solids of control, liquid, the transparent body, flexible body and smog with no damage.
The utility model embodiment batches drive system 3 one sides through optoelectronic switch 5 being arranged on foil mill, detects with it whether belt phenomenon takes place, and is accurately efficient, shortens signal reception, processing, the judgement time of existing disconnected paper tinsel protective device greatly.Be not only applicable to aluminium foil production, be applicable to the production of the foil and the wire rod of other materials too, like steel, copper, tin, paper, plastics etc.It below is specific embodiment.
