The working principle of the utility model are as follows: please refer to Fig. 1, Fig. 3, when diaphragm tensioning apparatus works, diaphragm 16 is counterclockwise
Direction bypasses the outer surface of roller 1, obtains larger cornerite as far as possible, improves frictional force, diaphragm 16 is from 1 lower section of roller with certain
Linear velocity leaves tensioning apparatus, passes to next station, i.e., on the deflector roll rotated coaxially with deflector roll motor 17, it is noted that in Fig. 3
The position of deflector roll motor 17 is only schematic diagram, does not represent deflector roll motor and is directly connected to diaphragm, the low rubbing cylinder 7 of upper end
Output end has certain intervening force, that is, the power for inhibiting swinging frame 3 to rotate around second bearing seat 15, when roller 1 to swinging frame 3 always
When diaphragm 16 between deflector roll motor 17 relaxes, swinging frame 3 is rotated clockwise around second bearing seat 15, generates angle displacement,
Referring to Fig. 1, the angle displacement is transmitted on gear wheel 11, gear wheel 11 is rotated, and the pinion gear 12 engaged is driven to rotate,
The pinion gear 12 that gear wheel 11 drives plays the role of amplifying rotational angle, and angle information is acquired by digital regulation resistance 13, uploads
To PLC controller, deflector roll motor 17 in PLC controller control figure 1 is accelerated the revolving speed of deflector roll motor 17, is made by deflector roll motor
The guide roller rotating speed of drive is accelerated, and restores tensioning state with metacneme 16, similarly, when diaphragm 16 is excessively tight, 3 inverse time of swinging frame
The angle information of needle rotation, rotation is handled by PLC controller, in feedback to deflector roll motor 17, reduces it by rotation speed, every
Film tensioning state restores normal, and the dynamic regulation of strainer may be implemented in this device, so that the stress of diaphragm 16 is in dynamic flat
Weighing apparatus state prevents the swing angle of swinging frame 3 in addition, preceding bumper post 9 and rear bumper post 10 play the role of limit to swinging frame
It is excessive.
The part being not directed in the utility model uses or uses for reference prior art and can be realized.
