Energy.
Embodiment 2: a kind of softness cloth unreels the control method of structure, as shown in Figures 1 to 4, is applied to control above-mentioned
One of embodiment softness cloth unreels structure, comprising:
S1: start passively to unreel, soft cloth is placed in conveyer belt 51, drives soft cloth to unreel forward by conveyer belt 51；
S2: detection unreels pressure value: unreeling main body 43 to the pressure of support frame 2 using the acquisition of pressure sensor 21；
(i) A≤B-C is worked as, and power source 6 is controlled by controller starting, screw lift structure 3 is driven to decline, and reduction unreels master
The height of body 43；
(ii) work as A > B-C and A < B+C, unreel main body 43 and be maintained at locating height；
(iii) A >=B+C is worked as, and power source 6 is controlled by controller starting, screw lift structure 3 is driven to rise, and raising unreels
The height of main body 43；
Wherein, A is the detected value of pressure sensor 21；B is setup pressure value；C is setting pressure limit deviation；
S3: control unreels speed: detecting real-time D value, and is matched with D value matching list is preset, is converted into corresponding
The output valve E of magnetic powder brake 421；
Wherein, D is the locating height of 311 real time position of screw rod；E is the output valve of magnetic powder brake 421；
S4: end unreels, and stops S2 and S3.
Wherein, pressure sensor 21, power source 6, magnetic powder brake 421 are electrically connected with the controller.
During soft cloth unreels, S2 and S3 are carried out simultaneously, and it is basis when in use which, which unreels structure,
Guillotine draw material situation carry out using whether, it is synchronous to carry out tension detection and the lifting of screw rod 311 simultaneously when guillotine draws material work
And the output of magnetic powder brake 421 is carried out simultaneously.Coil diameter is larger when starting, and when cloth is heavier, screw rod 311 is to be lifted up, magnetic
Powder braking output is smaller；At the end of more arriving, coil diameter is smaller, and when cloth is lighter, screw rod 311 has downward active force, while magnetic
Powder suitably increase a little export, guarantee unreel main body 43 no matter coil diameter size, all there is no folds for softness cloth when unreeling
With larger stretching.
Magnetic powder brake 421 provides brake force when starting to unreel and end unreels, and reduces soft cloth and goes out in start-stop
A possibility that existing fold or excessively stretching.
In this way, during soft cloth unreels silk can be adjusted in real time according to the coil diameter for unreeling main body 43
The height of bar 311 and the brake force of magnetic powder brake 421, during entirely unreeling, flexible cloth will not be deposited biggish
Fold and stretching, have the advantages that flexible cloth be unlikely to deform and unreel to cut station be not susceptible to offset.
The acquisition of pressure sensor 21 unreels main body 43 to the pressure of support frame 2, passes to controller, controller controls power
Source 6 acts, and adjusts the height of screw rod 311 in real time, makes to unreel main body 43 and is in preset range always to the pressure of support frame 2, guarantees
Soft cloth is not easy excessively to be stretched during unreeling, and reduces a possibility that soft cloth deforms；Meanwhile power source 6
Controller will be highly passed in real time locating for screw rod 311, controller is matched with the matching list preset, is converted into magnetic powder
The output of brake 421 provides real-time resistance for air-expanding shaft 42, guarantees that soft cloth is not susceptible to fold during unreeling,
It is not easy to shift during unreeling, improves the path accuracy of soft cloth.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
As long as all by the protection of Patent Law in the scope of the claims of the utility model.
