Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Referring to Figure 1 and Fig. 2, Fig. 1 are that the structure of uncoiler of rolling mill loose winding control system provided by the utility model is shown
It is intended to；Fig. 2 is the structural block diagram of uncoiler of rolling mill loose winding control system provided by the utility model.The uncoiler of rolling mill loose winding control
System processed includes: feeding roller 10, top pinch roll 11, rectification roll 12, band 13, uncoiler 20, spool 21, pressure arm oil cylinder 30, pressure
Arm shaft 31, uncoiling pressure arm 32, driving chain 33, pressure head roller 34 and nonwoven layer 35.
Feeding roller 10 includes the top pinch roll 11 and rectification roll 12 that are correspondingly arranged up and down, top pinch roll 11 and rectification roll 12 it
Between there are gap, be used to clamp band 13 and feeding forward when threading.Top pinch roll 11 and rectification roll 12 with the first hydraulic horse
