Description
Technical field
The utility model belongs to coiled material technical field, is related to a kind of unwinding device.
Background technology
Existing unwinding device includes mainly rack and unreeling shaft, is needed since material consumption is fast, when unreeling constantly more
Change of lap material, existing unwinding device structure is single, when change of lap, needs to shut down the unreeling shaft being arranged in rack and is split with rack
It is unreeled so that coiled material to be inserted in, cannot be satisfied the quick-replaceable to coiled material, efficiency is low.
Utility model content
To overcome deficiency in the prior art, the utility model to provide a kind of unwinding device, solve existing unwinding device
Structure is single, needs when change of lap to shut down and splits unreeling shaft and rack to be inserted in coiled material, cannot be satisfied to the quick of coiled material
It replaces, efficiency is low.
To achieve the above object, the technical solution adopted in the utility model is as follows：
A kind of unwinding device, it is characterised in that：Including rack, the reversing frame being rotatably provided in rack, it is oppositely arranged
First driving mechanism of two clamping devices, driving reversing frame overturning on reversing frame, the clamping device includes that opposite can move
Two slides on reversing frame are set dynamicly, the two gas expansion shaft heads that are oppositely arranged on two slides and driving two slides relative movement
The second driving mechanism.
Further, reversing frame includes interval two turntables being oppositely arranged and the crossbeam being connected between two turntables.
Further, the linear guide is provided on crossbeam, slide is slidably arranged in the linear guide.
Further, the first driving mechanism includes the shaft for connecting reversing frame, the worm gear being arranged in shaft, is arranged in parallel
Worm gear both sides and with two worm screws of worm gear engagement, motor, the retarder for connecting motor, be arranged on reducer output shaft the
It one gear, the third gear that the second gear engaged with first gear on a worm screw is set, is arranged on another worm screw and sets
Set two transition gears between second gear and third gear.
Further, the second driving mechanism includes respectively driving two leading screw and nut mechanisms of two slides movement.
Further, leading screw and nut mechanism includes that two feed screw nut pair disposed in parallel and two groups of feed screw nut pairs of driving are same
The motor of work is walked, motor is sequentially connected with two groups of feed screw nut pairs respectively by synchronizing shaft.
From the above description of the utility model, it can be seen, compared with prior art, a kind of unwinding device of the utility model,
Have the function of that stop reel-changing, gas expansion shaft head can not relatively move setting by clamping device at a high speed, convenient for unreeling, realize fast quick change
Volume does not have to shut down handling, and clamping device is two, can be improved and unreels efficiency.

Second gear 47, the third gear 48 that is arranged on another worm screw 43 and the setting of one gear 46 engagement are in second gear 47 and the
Two transition gears 49 between three gears 48.
A kind of above-mentioned unwinding device, the gas expansion shaft head 32 being arranged on slide 31 can relatively be slided along the linear guide 221,
It stretches into and is sleeved on gas expansion shaft head 32 convenient for the coiled material to be unreeled, it is convenient that coiled material is replaced, strong applicability, when ensureing Material cladding not
Dislocation does not have to handling gas expansion shaft head 32, realizes that not stop reel-changing function, two clamping devices 3 are arranged on reversing frame 2, raising is put
Roll up efficiency.
Several specific implementation modes of the utility model are above are only, but the design concept of the utility model is not limited to
This, all non-essential modifications to the present invention made by this concept should all belong to infringement scope of protection of the utility model
Behavior.
