Embodiment
The utility model preferred embodiment is described in detail below in conjunction with the accompanying drawings.
Please refer to Fig.1-2, a kind of warp let-off tension-adjusting gear of the utility model, including be oppositely arranged two wallboards 1,
The vertical rod 8 being rotatably installed on wallboard 1, is fixed with roller bearing 2 on the side of each wallboard 1, on roller bearing 2
Tension force pitman shaft 3 is rotatably mounted with, swing arm 4 is fixed with tension force pitman shaft 3, swing arm 4 can be along 3 footpath of tension force pitman shaft to the left
Right swing, the lower end of swing arm 4 are fixed with tension rail 5 and elastic component 6, and the one end of tension rail 5 away from swing arm 4 is connected to vertical rod 8
On.Tension rail 5 is through being arranged in elastic component 6, and the elastic component 6 in the present embodiment is spring 6, and spring material benefit is durable, installation
It is convenient.
Roller 10 is fixed with tension force pitman shaft 3, swing arm 4 is between roller bearing 2 and roller 10 so that tension adjustment
Shi Shouli is more balanced.The lower end of swing arm 4 offers the through hole passed through for tension rail 5.One end of tension rail 5 is fixed through through hole
In the bottom of swing arm 4, the other end is connected on vertical rod 8 by oscillating bearing 7.
Vertical rod 8 is rotatably installed on wallboard 1 on the side of roller 10 by vertical rod fixing axle 9, and vertically
Bar 8 extends perpendicularly to wallboard 1.
Warp let-off tension-adjusting gear further includes tension roller 11 and tension roller seat 12, and tension roller seat 12 is installed on tension force
On pitman shaft 3, between rolling stand 2 and roller 10 and close to the side of roller 10, the both ends of tension roller 11 are by opening
Power roller seat 12 is installed on tension force pitman shaft 3.
The both ends of tension force pitman shaft 3 are rotatably fixed on roller bearing 2.The extending direction of tension rail 5 connects with tension force
The extending direction of bar axis 3 is mutually perpendicular to.The extending direction of vertical rod 8 is identical with the extending direction of roller 10, i.e. tension rail 5 prolongs
Direction is stretched perpendicular to vertical rod 8 and the extending direction of roller 10.
When specifically used, when needing to increase tension force, vertical rod 8 is rotated, since one end of tension rail 5 is fixed through through hole
