Upper and its push rod is connect with 52 lower end of stirring hook.
For control pusher board member 3 storing rack 2 both ends extreme position accurate stopping, as of the invention one
It improves, is additionally provided with travel switch in 2 both ends extreme position of storing rack.
Embodiment 2:
For the feeding for adapting to strip material, the present embodiment is identical as 1 modular construction of embodiment, the difference is that by embodiment
At least 2 and at least 1 single track storing racks collectively constitute strip material charging equipment, such as Fig. 3 in feeding device described in 1
Shown, including single track storing rack 20 and feeding device above-mentioned 10, aforementioned feeding device 10 at least two and interval setting are preceding
State feeding device 10 it is adjacent between be provided with single track storing rack 20, the pusher board member 3 is synchronous or before asynchronously pushing
Strip material 6 on storing rack 2 and single track storing rack 20 is stated to aforementioned turn-down rig 5, then by it is aforementioned pull out turn-down rig 5 by
Root send strip material 6 into feeding roller-way folding ring 7.
A kind of feeding process that strip material charging equipment completes entire strip material is as follows:
A bundle of strip material 6 is hung to be sent on storing rack 2 and single track storing rack 20 by hoisting apparatus and is spread out, is pressed
It starts switch, motor 41, which starts to rotate forward to export through reduction gearbox 42, drives drive sprocket 43 to rotate, and transmits zone of action by chain 46
Dynamic driven sprocket 441 rotates together, storing rack 2 and single track of the scraping wings 32 of 46 drag start position of chain in rack 1
Storing rack 20 moves to the right, different in the case of the appearance head and the tail movement of strip material 6 is different extremely during push
Straightener charging equipment 10 can asynchronously make push movement to guarantee that head and the tail are mobile consistent, when long web according to current state
For 6 head and the tail mobile one of material in the case of, different straightener charging equipments 10 then synchronously makes push movement according to current state.
When 6 head and the tail of strip material are consistently pushed at stirring hook 52 by root, hydraulic cylinder 54 starts to act, and releases push rod and pushes stirring
Hook 52, initial position are in the stirring hook 52 of 2 lower section of storing stand frame under thrust, turn clockwise around the second rotary shaft 53
It moves to lift stirring hook 52 to hook strip material 6 to send and tumble into the feeding roller-way folding ring 7 opened, then feeding roller-way
It opens and closes the closure of ring 7 and starts straightening operation.Stirring hook 52 by strip material 6 hook send tumble to feeding roller-way open and close ring 7 after i.e.
It rotates counterclockwise during 54 pusher retracted of hydraulic cylinder around the second rotary shaft 53 and retracts below eave tile to storing rack 2 downwards
Prepare next hook of root long strip material 6 and pass through journey, until strip material 6 is all by root on storing rack 2 and single track storing rack 20
Hook is sent into folding feeding roller-way folding ring 7.At this point, hoisting apparatus, which hangs new a bundle of strip material 6, is sent to storing rack 2 and list
It on rail storing rack 20 and spreads out, the initial position on the left side is returned to without waiting for scraping wings 32, is equivalent to and shortens a job
Process.Driven sprocket member drives cylinder 45 retracts push rod and driven sprocket component 44 is driven to slide to the left along guide rail 442, scraping wings
32 lose 46 pulling force of chain and under the reset pulling force effect of spring 33, and scraping wings 32 is rotated clockwise around the first rotary shaft 34
Scraping wings 32 is pulled down and completes movement of bowing below eave tile to storing rack 2；Then, the reversion of motor 41 exports band through reduction gearbox 42
Dynamic drive sprocket 43 inverts, and is acted on by 46 transmitting of chain and driven sprocket 441 is driven to invert together, and chain 46 drags sliding floor
The 31 storing rack 2 in rack 1, which moves downward, returns to initial position, and later, the starting of driven sprocket member drives cylinder 45 is dynamic
Make, push rod is released, and driven sprocket component 44 is pushed to slide through 46 pulling function of chain to the right along guide rail 442, drives scraping wings
32 rotate counterclockwise around the first rotary shaft 34, and 32 eave tile of scraping wings rises from below storing rack 2 completes new line movement.So
Afterwards, start the pusher of a new round and by root feeding process.
Compared with prior art, the present invention passes through " storing rack " directly to serve as the functional area of material stock and feeding, contracts
A short workflow, improves loading efficiency.Mode is pushed using the simple scraping wings of structure simultaneously, eliminates relation line
The configuration of pipe, tracheae, hydraulic tube, overall structure is simpler, succinct and neat, while pusher, feeding performance are more reliable and more stable.
Detailed description is made that embodiments of the present invention in conjunction with attached drawing above, strip material used in the present invention refers to
Elongated strip material made of a variety of materials, as long as the mobile feeding of the strip material can carry out feeding using the present invention.Meanwhile
The present invention is applicable not only to straightener feeding, needs to be delivered to another platform or equipment by root in all similar material loading platforms or equipment
It is applicable, and within the scope of the present invention.But the present invention is not limited to described embodiment, for this field
For technical staff, without departing from the principles and spirit of the present invention, various change is carried out to these embodiments, is repaired
Change, replacement and variant is still fallen in protection scope of the present invention.
