On slide bar 11, the rack 1 of 2 top of buffer roll is equipped with two deflector rolls 3 parallel with buffer roll 2, and two deflector rolls 3 are located at slow
The both sides of roller 2 are rushed, deflector roll 3 and buffer roll 2 are distributed in up-side down triangle in rack 1;
A gear 4 is respectively provided in rack 1 above and below 2 both ends of buffer roll, a circle is equipped between two gears 4
Chain 41, the sliding block 21 at the both ends of buffer roll 2 are fixed on chain 4, and clump weight 42 is hung on the chain 4;
It is located in the rack 1 in the vertical region at 11 place of slide bar and sets by two 51 groups of inductance approach switches one on the other
Into bistable switch 5,51 be horizontally directed to slide bar 11 close to switch, bistable switch 5 is connected with controller 6, the controller 6 and
Winder 7, which is connected, controls rolling speed, and frequency converter, controller 6 and discharging are equipped between controller 6 and the motor of winder 7
Machine 8, which is connected, controls production discharging speed;
Any gear 4 is equipped with coaxial pinion 43 in the gear 4, and pinion 43 is by chain 41 and is set in rack 1
Driven gear 44 connect, the shaft of driven gear 44 is mounted on by bearing 45 in rack 1, is equipped between shaft and rack 1
Potentiometer 52, rack 1 are equipped with hand from switch 53 is controlled, and potentiometer 52 and hand control switch 53 to be connected with frequency converter certainly;
The side of the sliding block 21 of the buffer roll 2 is equipped with the horizontally disposed two pieces of connecting plates 211 being connect with chain 41, chain
41 both ends respectively connect a leading screw 212 by hinge, and the leading screw 212 of 41 upper end of chain is passed down through top connecting plate 211 and leads to
Screw on nut behind hole, the leading screw 212 of 41 lower end of chain screws on nut after being upward through the through-hole of lower section connecting plate 211, tightens spiral shell
Cap makes chain 41 be tightened on gear 4, and the size of through-hole is more than leading screw 212 and is less than nut;
The upper and lower part of the slide bar 11 is equipped with buffer spring 111, and the upper close switch 51 is located at upper buffer spring 111
Lower section, the lower top for being located at lower buffer spring 51 close to switch 51;
The rack 1 of the lower section of the deflector roll 3 of the tension bracket discharging side is equipped with lower guide reel 31;
A pressure roller 32 is installed in the top of the deflector roll 3 of the tension bracket top discharge side by hinge, and pressure roller 32 is because of its own gravity
Downward around hinge rotation is pressed on deflector roll 3, and pressure roller 32 is identical with the length of deflector roll 3.
IXPE foams lengthy motion picture is above a deflector roll downwards around from buffer roll lower section across again upwards around another deflector roll
Top after be pierced by, then access winder, when the rolling speed of winder and inconsistent discharging speed, in deflector roll and buffer roll
Between foam tension change, buffer roll is moved up and down with the influence of tension and its own gravity, automatically adjust tension, balance
Rolling speed and discharging speed ensure product quality and winding effect;The setting of chain, gear, clump weight, can be according to difference
The position of foam adjustment suspended counterweight block of specification and the quality of clump weight, clump weight are suspended on the chain of buffer roll side,
It is then the weight for increasing buffer roll, is suspended on the chain of opposite side, is the weight for mitigating buffer roll, is adjusted flexibly, uses model
It encloses more extensively, tension adjustment is more accurate;
During normal work, foam lengthy motion picture lifts buffer roll between two inductance approach switches, inductance approach switch
With the setting of controller, by discharging machine, tension bracket, winder linkage get up, be located above close to inductive switching to buffer roll
Continue upward it is mobile higher than the upper height close to switch constantly, illustrate that the tension of winding becomes larger, deliver a signal to controller, control
Device control rolling speed processed slows down and/or accelerates discharging speed, and buffer roll is made to fall after rise to two close between switching, if conversely,
It senses that chain is persistently moved down less than lower close to when switching, illustrates that the tension of winding becomes smaller, deliver a signal to controller, control
Device control rolling speed processed is accelerated and/or slows down discharging speed, buffer roll is made to go back up to two close between switch, the system is certainly
It is dynamic that discharging machine, tension bracket, winder linkage is made to reach balance, ensure production efficiency and winding effect;
Hand Zi control switch rotary arrive when automatically controlling, when the fold on foam by tension bracket when, due to buffer roll weight
It influencing, fold is stretched stretching, extension, can cause buffer roll small size Drop shock downwards at this time, while drive the rotation of driven gear,
Potentiometer shifts, and according to the different ratios that pinion and driven gear are set, potentiometer delivers a signal to frequency converter, becomes
Frequency device quickly controls the motor speed of winder quickly to change, and moment accelerates, and moment slows down, changes the tension of foam, make tension
Buffer roll is shaken up and down on frame, and when hand, Zi switch rotary is controlled, to during manual control, hand is controlled to switch and be delivered a signal to certainly
Frequency converter, frequency converter quickly change according to the rotating speed of pre-set FREQUENCY CONTROL winder, and moment accelerates, moment slows down, and makes
Buffer roll occurs to shake up and down, further evens up fold part and stretches, ensures winding effect and quality;
It is fixed between buffer roll and chain using screw and nut, not only facilitates and chain is installed on gear, but also can root
According to needs, the degree of tautness of chain is adjusted, is preferably used cooperatively with the clump weight being suspended on chain;
The setting of the spring of slide bar upper and lower part acts not only as positioning limit use, determines what buffer roll slided up and down
Range, and when buffer roll quickly moves up and down, to be contacted with buffer roll when, provide buffering, prevent buffer roll from occurring with rack
It hits and generates strong vibration, damage foam lengthy motion picture, influence product quality;
The setting of lower guide reel is to coordinate the wind-up roll that height is different on winder, and the height of wind-up roll is higher, then directly
Wind-up roll is accessed after being pierced by from the deflector roll of top, if the height of wind-up roll is relatively low, foam lengthy motion picture will be pierced by from top deflector roll again
It is pierced by from lower guide reel, finally accesses on wind-up roll;
The setting of pressure roller is that foam lengthy motion picture is pressed on deflector roll, if the fixation without pressure roller, foam lengthy motion picture is in relatively loose state
Lower meeting sideslip, foam lengthy motion picture in this case is when entering winder, it is easy to which generation winding is uneven, causes scroll side not
Smooth, after setting pressure roller, what can be stablized controls the position of foam lengthy motion picture, ensures the stabilization of winding, further improves winding effect.
The present invention not only by theory of mechanics adjust winding tension, but also by control system by winder, tension bracket, go out
Material machine links, autobalance rolling speed, discharging speed, adjusts winding tension, the even more quick change by controlling rolling speed
Change, shake buffer roll, even up the fold of long on piece, ensure that winding effect, scroll side wall flatness is high, prevents
During transport and storage, the side of scroll material protrudes material and is damaged caused by the reasons such as squeezing, and influences product quality, makes
With conveniently, automatic degree is high, greatly improves product quality and image product, and great economic benefit is created for company.
