For movable installation board 600, so as to tighten driving belt 400.
Fig. 4 to Fig. 5 is referred to, driving belt 400 includes upper belt 41 and the lower belt 42 being connected with upper belt 41.Transmission
Belt stretcher also includes tension structure 500, and tension structure 500 includes the first directive wheel 51, the second directive wheel 52, tensioning wheel
53 and stress component 54 is pulled, the first directive wheel 51 and the second directive wheel 52 are positioned at one of fixed plate 100, tensioning wheel 53
Be positioned at fixed plate 100 and rotated relative to fixed plate 100, pull stress component 54 to be connected with tensioning wheel 53, lower belt 42 according to
It is secondary to bypass the first directive wheel 51, the directive wheel 52 of tensioning wheel 53 and second, pull stress component 54 to pull tensioning wheel 53 along fixation
Plate 100 is directed away from the direction movement of upper belt 41, so as to be tensioned driving belt 400.
In the present embodiment, pull stress component 54 to pull tensioning wheel 53, make the lower belt 42 being around on tensioning wheel 53
Move in the direction that upper belt 41 is directed away from along the first directive wheel 51 and the second directive wheel 52.During pulling, transmission
The elasticity of itself of belt 400 tightens upper belt 41, the pressure of upper belt 41 and active live-roller 200 and slave drive roller 300
Power increase, driving belt 400 is pressed on active live-roller 200 and slave drive roller 300, so as to add active live-roller
200th, the frictional force between slave drive roller 300 and driving belt 400, driving belt 400 and slave drive be effectively prevent
The situation that roller 300 skids occurs.
In the present embodiment, tensioning wheel 53 is positioned in fixed plate 100, and is rotated.Stress component 54 is pulled to pull
During tensioning wheel 53 moves, tensioning wheel 53 is also moved and rotated with driving belt 400, and the tensioning wheel 53 of rotation reduces biography
Dynamic frictional force between belt 400 and tensioning wheel 53, excessive wear of the tensioning wheel 53 to driving belt 400 is prevented, so as to cause
Driving belt 400 damages.
Further, 53 arrangement triangular in shape of the first directive wheel 51, the second directive wheel 52 and tensioning wheel.
In the present embodiment, tensioning wheel 53 is between the first directive wheel 51 and the second directive wheel 52, and lower belt 42 is certainly
Tensioning wheel 53 extends to the first directive wheel 51 and the second directive wheel 52 of the both sides of tensioning wheel 53 respectively, in the tension of tensioning wheel 53
When dynamic stress component 54 pulls, lower belt 42 with the first directive wheel 51 and the second directive wheel 52 for two fulcrums, to propping up
The upper belt 41 in point outside acts on, and tightens upper belt 41.The setting of first directive wheel 51 and the second directive wheel 52, also simultaneously
The stabilization of driving belt 400 and active live-roller 200 and the contact surface of slave drive roller 300 is ensure that, prevents transmission
The reduction of belt 400 and active live-roller 200 or the contact surface of slave drive roller 300, lower belt 42 is in active live-roller 200
Or the opening position of slave drive roller 300 and the change of the angle of upper belt 41.When the change in location or lower belt of contact surface
42 with the variable angle of upper belt 41 in the case of, can cause during tensioning wheel 53 is pulled, the inequality of the tension force of upper belt 41
Even change, shakes upper belt 41, further causes slave drive roller 300 to rotate unstable situation and occurs.
Further, the first directive wheel 51 and the second directive wheel 52 rotate relative to fixed plate 100.
In the present embodiment, the first directive wheel 51 and the second directive wheel 52 and rotate, driving belt 400 is the
One directive wheel 51 and the second directive wheel 52 move while rotation, likewise, the first directive wheel 51 and second that rotate are led
Reduce the abrasion to driving belt 400 to wheel 52, reduce the risk of the damage of driving belt 400.
Further, stress component 54 is pulled to include：Be slidably installed block 541, fixed block 542, pulling screw rod 543 and bullet
Spring 544, the block 541 that is slidably installed is positioned at fixed plate 100, and is moved relative to fixed plate 100；Fixed block 542 is fixed on fixation
On plate 100 and positioned at being slidably installed on the moving direction of block 541；The one end of screw rod 543 is pulled to be positioned at fixed block 542, the other end
Towards the block 541 that is slidably installed；One end of spring 544 is positioned at the block 541 that is slidably installed, and the other end, which is fixed on, pulls screw rod 543；Bullet
Spring 544 is in extended configuration, for pulling the block 541 that is slidably installed to be moved towards the side of fixed block 542；Tensioning wheel 53 is positioned at
Be slidably installed block 541, and with the synchronizing moving of block 541 that is slidably installed.
In the present embodiment, the one end of spring 544 is positioned at the block 541 that is slidably installed, and the other end, which is positioned at, is fixed on fixation
On fixed block 542 on plate 100, so that the block 541 that is slidably installed slides relative to fixed plate 100, be slidably installed the band again of block 541
Dynamic tensioning wheel 53 slides, and realizes tightening for driving belt 400, whole fixed form is fairly simple, and cost is relatively low.
Preferred embodiment of the present utility model is these are only, it is all in this practicality not to limit the utility model
