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 Fig. 1, in the utility model embodiment, a kind of electrodes of lithium-ion batteries tension-adjusting gear, including rack,
Drive roll 1 is equipped in rack, 1 one end of drive roll is equipped with motor 2, and motor 2 is fixedly installed on a side frame, and then is drive roll
1 provides rotational power, and 1 lower end of drive roll is equipped with rubber roller 3, and 3 both ends of rubber roller are equipped with adjustment portion, and adjustment portion includes 4 He of regulating arm
Regulating mechanism is connect in the middle part of regulating arm 4 with gantry rotation by fulcrum 5, and then formation lever mechanism, 4 one end of regulating arm and glue
Roller 3 connects, and the other end of regulating arm 4 is connect with regulating mechanism, and regulating mechanism includes resetting-mechanism 8 and micro-adjusting mechanism, resets machine
Structure 8 includes the storage force mechanisms connecting with rack, and accumulation mechanism is one of spring, cylinder, hydraulic cylinder, and the present embodiment selects gas
Cylinder, the pistons end of cylinder are connected with connecting rod 6, and connecting rod is articulated and connected by hinged seat 7 and regulating arm 4, and then can be led to
Crossing cylinder is that regulating arm 4 provides reset power, and micro-adjusting mechanism includes the support 12 being fixedly connected with rack, and 12 upper end of support is equipped with
The thickness of voussoir 11, voussoir 11 has one end to gradually increase to the other end, and adjustment bolt is equipped between 11 one end of voussoir and support 12
13, and then horizontal sliding can be carried out on support 12 with dynamic voussoir 11 by adjusting bolt 13,4 end of regulating arm passes through connection
Axis 9 is connected with idler wheel 10, and the rolling of idler wheel 10 is crimped on 11 upper surface of voussoir, and then can be by adjusting voussoir 11 and idler wheel 10
