Detailed description of the invention
Below in conjunction with the accompanying drawing of this specification sheets, elaboration is further given to preferred embodiment of the present utility model.
See the structural representation that Fig. 4 A, Fig. 4 B and Fig. 5, Fig. 4 A and Fig. 4 B are tension control mechanisms of the present utility model.Fig. 5 is the principle of work signal of tension control mechanism of the present utility model.Tension control mechanism 10 of the present utility model roughly comprises: floating roller 1, for control this floating roller 1 action motor 2, for connecting 6, one, driving section clump weight 7 and two adapter plates 9 of this floating roller 1 and motor 2.Preferably, this motor 2 has torque adjustment function.
Particularly, this driving section 6 comprises two other synchronizing wheel 64 being installed in two synchronizing wheels 62 at the two ends of this transmission shaft 61, two Timing Belts 63 coordinated with these two synchronizing wheels 62 by the transmission shaft 61 of the output shaft driven rotary of this motor 2, compartment of terrain and being coordinated with these two Timing Belts 63.The two ends of floating roller 1 are installed on these two Timing Belts 63.Clump weight 7 is installed on these two Timing Belts 63.It is worth mentioning that, the installation position of clump weight 7 on two Timing Belts 63 and the installation position of two ends on two Timing Belts 63 of floating roller 1 are relative before and after being, the setting of clump weight 7 can overcome the deadweight of floating roller 1 to the impact of the operation of Timing Belt 63.This structure, the two ends synchronous linear that this motor 2 can order about this floating roller 2 moves, to reach the object controlling tension force.
Described floating roller 1, motor 2 and driving section 6 are installed on these two adapter plates 9.Particularly, described floating roller 1 and transmission shaft 61 are installed between these two adapter plates 9, and described motor 2 is installed in the outside of one of them adapter plate 9.Sliding block joint between the two ends of this floating roller 1 and this two adapter plates 9.In the present embodiment, overlap sliding-rail sliding by two between the two ends of this floating roller 1 and this two adapter plates 9 and combine 65 sliding block joints.Specifically, often overlap sliding-rail sliding combination 65 and comprise the line slide rail 651 be installed on adapter plate 9 and the slide block 652 be installed on Timing Belt 63 further.
Tension control mechanism 10 of the present utility model coordinates with two mistake rollers 20, and band 30 can be made to produce necessary tension force.Specifically, motor 2 can drive Timing Belt about 63 to move linearly via synchronizing wheel 62,64, and then moves with the floating roller 1 be fixed on Timing Belt 63, thus can strain band 30 and make band 30 produce necessary tension force.In the present embodiment, floating roller 1 pair of band 30 produces downward application force 2F, crosses roller 20 for two and produces upwards directed force F to band 30 respectively.
Compared with prior art, tension control mechanism of the present utility model, by adopting transmission shaft 61, two synchronizing wheels 62 and two Timing Belts 63 to realize the driving of motor 2 to the two ends of floating roller 1 dexterously, floating roller 1 can be made to move linearly, to reach the object controlling tension force; Further, owing to adopting the synchronization transmission structure of Timing Belt 63-synchronizing wheel 62,64, the synchronism of the two ends movement of floating roller 1 improves greatly, and the tension force on material both sides can be well controlled, and there will not be tightly, situation that another side send; In addition, owing to adopting motor 2 to drive, position and the torsion of floating roller 1 all can obtain accurate control, and tension fluctuation is very little, thus can realize the accurate control of tension force.
