Specifically, pretension fixing device 100 generally includes provides the actuating unit 110 of scalable pulling force, wheel to be pivotally connected to this
The action-oriented wheel 120 of actuating unit 110, it is arranged at entering directive wheel 130, being arranged at pretension fixing device of pretension fixing device 100 arrival end
100 ports of export go out directive wheel 140 and for the drive directive wheel 150 driving chain 400 to advance.In the reality shown in Fig. 1
Execute in example, have three enter directive wheel 130 and loading in advance in pretension fixing device 100 arrival end (left side in Fig. 1) interlaced arrangement
Putting 100 ports of export (right side in Fig. 1) interlaced arrangement has two to go out directive wheel 140, and drive directive wheel 150 is then arranged at out and leads
Side to the wheel 140 inclined ports of export.Chain is walked around into directive wheel 130, action-oriented wheel 120 successively, is gone out directive wheel 140 and drive
Power directive wheel 150 is advanced.Action-oriented wheel 120 moves radially under the driving of actuating unit 110, with by increasing or reducing chain
The pulling force of bar 400 is strained or loosens chain 400.In embodiment of the present utility model, it is possible to use oil cylinder is as engine
Structure 120.
The partial view of Fig. 1 and Fig. 2 are the schematic diagram of detection device 200 of the present utility model.As it can be seen, detection dress
Put 200 and totally comprise chain inlet/outlet mechanism 210, fixed plate 220, movable sprocket 230, survey tool 240 and tension spring 250.
Enter detection device 200 from pre-tightening apparatus 100 chain 400 out by chain inlet/outlet mechanism 210, and walk around movable sprocket
Again detection device 200 is left from chain inlet/outlet mechanism 210 after 230.Chain inlet/outlet mechanism 210 is able to ensure that and is positioned at detection device
Chain joint number in 200 is definite value, and the length being beneficial to the chain by constant joint number controls in predetermined scope.In this practicality
In novel embodiment, chain inlet/outlet mechanism 210 comprises one to be determined sprocket wheel 211 and is arranged on and determines sprocket wheel 211 away from movable sprocket 230
The first little guide wheel 212 and the second little guide wheel 213 of side.So from pre-tightening apparatus 100 chain 400 out can successively around
Cross the first little guide wheel 212 and determine side (for left side in Fig. 2) the entrance detection device 200 of sprocket wheel 211, walking around movable sprocket 230
After walk around successively and determine the opposite side (in Fig. 2 for right side) of sprocket wheel 211 and leave detection device 200, owing to chain 400 is into and out of detection
Device 200 all through with certain sprocket wheel 211, just can ensure that and has while having a chain to enter detection device 200
A chain leaves detection device 200, so that it is guaranteed that the chain joint number being positioned at detection device 200 is definite value.Preferably, first
Little guide wheel 212 and the second little guide wheel 213 can be close proximity to determining sprocket wheel 211, so that chain 400 is fully contacted with determining sprocket wheel 211,
Prevent chain from departing from and determine sprocket wheel 211.
Movable sprocket 230 may be movably attached in fixed plate 220.In embodiment of the present utility model, movable pulley 230
It is fixed with slide block on wheel shaft, and a part for this slide block is defined in the slide rail being arranged in fixed plate 220, so that movable sprocket
230 can move radially relative to fixed plate 220.It is further fixed in fixed plate 220 for measuring movable sprocket 230 and determining sprocket wheel
The survey tool 240 of the spacing of 211.Use the grating scale shown in Fig. 3 as measuring work in embodiment of the present utility model
Tool 240, specifically, can be fixed on grating scale main body 241 in fixed plate 220, and by read head 242 and movable pulley 230 wheel shaft
On slide block connect.One end of tension spring 250 is fixed in fixed plate 220, and the relative other end is then fixed to movable sprocket 230
Wheel shaft on, in order to the pulling force being supplied to chain 400 is finely adjusted.
The chain pretension system of the application is mainly operated by following steps:
Preparation process: chain 400 is walked around successively pretension fixing device 100 enter directive wheel 130, action-oriented wheel 120, go out guide
Wheel 140, drive directive wheel 150 and the first little guide wheel 212 of detection device 200, determine sprocket wheel 211, movable sprocket 230, determine chain
Wheel 211 and the second little directive wheel 213, make chain 400 advance under the driving of drive directive wheel 150；
Detecting step: detection device 200 measures movable sprocket 230 and the distance determined between sprocket wheel 211 automatically, and by measured value
Send to controlling device 300；
Set-up procedure: control device 300 by the ultimate range of the measured value that receives and predetermined distance range and narrow spacing
From comparing, and according to this compare instruction pretension fixing device 100 size of pulling force is adjusted.
In set-up procedure, predetermined distance range may be set to the length of the predetermined joint number chain 400 through detection device 200
Movable sprocket 230 corresponding when degree is in preset range and the distance range determined between sprocket wheel 211.Therefore, it is more than when measured value
During ultimate range, illustrating that constant joint number chain 400 total length is long, the pulling force that i.e. chain 400 bears is excessive, controls device 300
The actuating unit 110 of instruction pretension fixing device 100 reduces pulling force, till measured value is decreased in predetermined distance range；On the contrary,
When measured value is less than minimum range, illustrating that constant joint number chain 400 total length is too short, the pulling force that i.e. chain 400 bears is too small,
Controlling device 300 indicates the actuating unit 110 of pretension fixing device 100 to increase pulling force, until measured value increases to predetermined distance range
Till Nei.This ensure that the length of constant joint number chain 400 changes in preset range.Preferably, controlling device can
To preset lowest pull and maximum pull, when value of thrust be reduced to below lowest pull value or increase to maximum pull value with
When after upper, measured value recovers to predetermined distance range not yet, it is possible to occurred that chain departs from the faults such as sprocket wheel, now chain
The pre-pull system of bar can be automatically stopped operation and send alarm.
Above-mentioned detecting step and set-up procedure are all carried out in chain traveling process in real time, make chain tension state and pulling force
Realize balance, it is ensured that the chain dimension produced is unified, good stability, and is effectively increased production efficiency.
Embodiment described above only have expressed embodiment of the present utility model, and it describes more concrete and detailed, but also
Therefore the restriction to this utility model the scope of the claims can not be interpreted as.It should be pointed out that, for the ordinary skill of this area
For personnel, without departing from the concept of the premise utility, it is also possible to make some deformation and improvement, these broadly fall into this
The protection domain of utility model.Therefore, the protection domain of this utility model patent should be as the criterion with claims.
