4 circular groove 41 is slidably connected, while passing through the tightening of conveyer belt 3, and the second rotating roller 21 and third rotating roller 22 is fixed
On rest pad 4.
One end far from the second rotating roller 21 or third rotating roller 22 on rest pad 4 offers fixing piece, fixing piece setting
For screw rod 6, the position that screw rod 6 is corresponded on rest pad 4 offers the threaded hole 42 being connected to circular groove 41,6 precession spiral shell of screw rod
One end in pit 42 and one end that guide rod 5 is slidingly attached to circular groove 41 are inconsistent, and the other end of screw rod 6 stretches out screw thread
Hole 42 to outside.
When conveyer belt 3 loosens, staff can rotate screw rod 6, make screw rod 6 threadingly hole 41 towards the second rotating roller
21 or third rotating roller 22 direction it is mobile, while guide rod 5 being pushed to move, guide rod 5 is made to drive the second rotating roller 21 or the
Three rotating rollers 22 are moved to the direction far from rest pad 4, so that conveyer belt 3 be adjusted, it are made to be in tensioning state always,
To improve the service life of transmission device.
As shown in Fig. 2, screw rod 6, which stretches out on threaded hole 42 to external cylinder, is threaded with nut 7, when staff is logical
Cross rotation screw rod 6 and Fig. 1 be shown in conveyer belt 3() rate of tension adjust after, nut 7 is threaded to contradict with supporting block 4, for pair
Screw rod 6 is fixed, the vibration for preventing transmission device from generating during long-time service, and screw rod 6 is made to loosen and cause to transmit
Rate of tension with 3 is inadequate.
As shown in Fig. 2, in order to prevent rotating nut 7 when, nut 7 from the end of screw rod 6 be detached from, screw rod 6 far from bearing
The circular anti-off board 61 in one end affixed one outside block 4,61 diameter of anti-off board is greater than 6 diameter of screw rod, for limiting nut 7
Position.
As depicted in figs. 1 and 2, when conveyer belt 3 loosens, then loose nut 7 first rotates screw rod 6, make screw rod 6 to
To push guide rod 5 to move, guide rod 5 drives rotating roller to transport to the direction far from rest pad 4 for the direction movement of guide rod 5
It is dynamic, so that conveyer belt 3 is in tensioning state.To improve the rate of tension of conveyer belt 3, finally tightening nut 7 again, make screw rod 6
It is fixed.
The course of work:, may between rotating roller and conveyer belt 3 when conveyer belt 3 fluffs by prolonged use is elongated
Phenomena such as will appear skidding.At this point, loose nut 7 first, then rotates screw rod 6, screw rod 6 is made to push guide rod 5 to second turn
The direction movement of dynamic roller 21 and third rotating roller 22 is tensioned conveyer belt 3, most to make guide rod 5 that conveyer belt 3 be pushed to move
It is in tightening nut 7 that screw rod 6 is fixed afterwards.
Embodiment 2: a kind of transmission device of adjusting tensioning degree, as shown in Figure 3 and Figure 4, difference from Example 1 exists
In the fixed form for fixing the second rotating roller 21 and third rotating roller 22, the lower surface of supporting block 4 is connected with fixed plate 8, fixed
It is opened up vertically on plate 8 there are two the sliding slot 81 being parallel to each other, the position of the corresponding sliding slot 81 of rack 1 offers connecting hole, rest pad 4
By the way that the positioning bolt 82 at sliding slot 81 is arranged in, screwed also cross sliding slot 81 and connecting hole and by location nut 83, from
And supporting block 4 is fixed in rack 1, fixed block 4 is abutted against with rack 1 at this time.In order to increase the stability of positioning, spiral shell is positioned
Gasket 84 is socketed on bolt 82, when positioning bolt 82 is tightened, gasket 84 be pressed in positioning bolt 82 and fixed plate 8 it
Between.
As shown in Figure 3 and Figure 4, when conveyer belt 3 fluffs by prolonged use is elongated, rotational positioning nut 83 makes fixed
Position bolt 82 loosen, then along the chute 81 upward or downward adjust fixed plate 8 position, to make the second rotating roller 21 and third
Rotating roller 22 is moved upwardly or downwardly, and again screws location nut 83 after adjustment, and transmission belt 3 is by second turn at this time
Dynamic roller 21 and third rotating roller 22 strut outward, improve the rate of tension of conveyer belt 3.In combination with embodiment 1, in embodiment 2
Scheme can play the role of auxiliary adjustment with 3 rate of tension of conveyer belt.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
