The adaptive feeder working principle of the thin steel strip identical tension of the present embodiment and the service condition of each device are as follows:
Steel band is placed on pallet with coiling stacked, is turned to rack and is rotated by 90 ° outward while three-dimensional regulation unit being driven to turn
It is dynamic, pallet is placed on rotation charging tray from tail end entrance containing steel band using fork truck, resets and turns to rack, dismantle steel band the top band
Volume, strip ends sequentially pass through roll surface after slewing rollers, roll surface, dancer lower roll surface, export orientation roller upper roller on entrance guide roller
Face, guiding screed units, into steel band traction unit 9.
Referring to Fig. 3, speed adaptive unit shown in three-dimensional regulation unit and Fig. 5, steel band is oriented to via slewing rollers and entrance
Roller realizes that vertical-flat turn is changed, and 207 lead agency of adjusting handle, which moves up and down, makes band transmission process and coil of strip not interfere and turn
To smooth, 208 lead agency of adjusting handle, which moves horizontally, makes band and band traction mechanism be in same center line, adjusting handle
204, which change slewing rollers inclination angle, obtains and the better compactness of band.Entrance and exit guide roller and dancer rib are adjusted,
Constraint band moves horizontally；It adjusts and is oriented to screed units handwheel 806, gap between locating back and band, reaches pressing in adjustment
With removal band dirt.By adjusting the rib of each roller and being oriented to screed units upper and lower gap and horizontal direction constraint, Ke Yishi
The adaptive feeding of thin strip of existing plurality of specifications.
The adaptive feeding schematic illustration of steel band identical tension referring to fig. 2, incipient stage feeder are in original state, float
Dynamic roller is under clump weight effect on least significant end hydraulic buffering mechanism, and band traction mechanism drives band to lead after operation starting
Draw speedV TractionTravel forward, at the same drive dancer, tension clump weight, magnetic suspension sliding block with sliding block along guide rail to floating
Dynamic, magnetic suspension sensor mechanism returns the movement control of servo control unit by the position signal Real-time Feedback that magnetic suspension sliding block transmits
System processed, the displacement operation passed back inside kinetic control system according to each position of displacement sensor from top to bottom are raw
At revolving speed from small to large, and this revolving speed is sent to servo control unit and drives servo motor rotation, as dancer is transported upwards
Dynamic process, servo motor revolving speed increase therewith, until the feeding speed that revolving speed generatesV FeedingWith the hauling speed of steel band traction unitV TractionThis revolving speed and dancer position are maintained when consistent, as steel band consumption tep reel radius can reduce, in order to maintain feeding speedV FeedingWith hauling speedV TractionIdentical, dancer, which can gradually float, increases the revolving speed of servo motor to reach this equilibrium state, watches
Dress system high-speed response feature just can solve this problem；System can be according to hauling speedV TractionVariation with steel belt disk is done
Speed adaptive changes out, while keeping feeding process strap tension constant.
By taking stainless steel DN10 corrugated pipe forming line feeding as an example, stainless strip feeding, choosing are carried out using present device
It is 38mm with strip width, wall thickness 0.2mm, the 6-7 volumes of SUS304 stainless strip that tep reel initial diameter is 1000mm, feeding
Speed is 2.6m/min.
1, rack being turned to first and being turned out 90 °, 6-7 volumes 1.5 tons or so of SUS304 stainless strip is utilized into fork
Vehicle is placed in feed rotary table together with pallet, is resetted and is turned to rack；
2, band band volume felt paper topmost is cut along band volume inside, extraction strip ends sequentially pass through roll surface after slewing rollers, enter
Roll surface on mouthful guide roller, dancer lower roll surface, roll surface and band guiding flattening mechanism enter band dragger on export orientation roller
Structure；
3, adjustment three-dimensional regulation unit up and down, horizontal and inclination angle, so that band is smoothly carried out the flat torsion of Li-, increase band and turn
It is contacted to roller roll surface, and is in band on feeding center line；
4, the rib spacing for adjusting each roller, is advisable with 38-38.5mm；It adjusts band and is oriented to screed units upper and lower gap, with 0.21-
0.22mm is advisable, at the same adjust guide bearing with contact steel band with band rotation be advisable；
