Description
Technical field
This utility model relates to a kind of unreeling structure, belongs to paper and cuts field.
Background technology
In film processing technique field, film surface is processed, need to use unwinding device and wrap-up, the film of rolling is scattered and processes the film scattered by unwinding device, film after process is wound into volume a volume again by wrap-up, unreeling structure of the prior art, owing to the film weight ratio of rolling is bigger, it is relatively difficult for being placed on unreeling structure by the film of rolling, after film is placed on unreeling structure, its stability is also difficult to ensure that, if the shakiness of placement, may rock during unreeling and even fall down from unreeling structure, thus the process that impact is to film, and after having unreeled, empty spool puts down from unreeling structure also whole needs manually carry out, human input is big.
Summary of the invention
The purpose of this utility model is to provide a kind of unreeling structure, solves the film of rolling is placed in prior art on unreeling structure difficulty and places unstable technological deficiency.
For solving the problems referred to above, technical solution adopted in the utility model is:
A kind of unreeling structure, including unreeling support, two material walls and two mousing-hooks, the top unreeling support has the first U-lag for supporting Scroll, two material walls rotate to be arranged on and unreel support bottom and material wall driving means driving rotation by being arranged on and unreeling on support, the free end playing material wall has the second U-lag for holding up unreeling shaft, two mousing-hooks rotate to be arranged on and unreel on support, and mousing-hook is driven by mousing-hook driving means and rotates.
Before the film of rolling is placed on unreeling structure, playing material wall driving means has driven material wall to rotate, before making the second U-lag be positioned at the spool of film, promote the film of rolling, the spool making film is positioned at the top of the second U-lag, playing material wall driving means has driven material wall to rotate up, spool is stuck in the first U-lag, mousing-hook driving means drives mousing-hook to rotate, catch on spool, make it can not drop in the first U-lag, spool is placed stable on unreeling structure, this process manually-operated be only spool is placed on unreeling structure before, remaining is without manual hand manipulation, the spool unreeled is taken off from unreeling structure, only action above need to be driven in the opposite direction.
As further improvement of the utility model, the described material wall driving means that rises is oil cylinder, its cylinder body is rotatably installed in and unreels on support, and the piston rod of oil cylinder is rotationally connected with playing material wall, and this position being rotationally connected is being played material wall and unreeled between position and the second U-lag that holder pivots is connected.
Oil cylinder is conventional executive component, cheap, its precision controlled is higher, the contraction of the piston rod of oil cylinder has driven material wall to be rotated up, the spool being placed on material wall in the second U-lag is held up to the first U-lag, after having unreeled, the elongation of the piston rod of oil cylinder, material wall has been driven to rotate down, will be located in the spool in the first U-lag to lift to relatively low position, the spool after having unreeled is empty reel spool, and its weight is the least, and be in a relatively low position of ratio, can manually by its from expect to take off on wall.
As further improvement of the utility model, described mousing-hook driving means is the first cylinder, the cylinder body of the first cylinder is arranged on and unreels on support, mousing-hook is L-shaped, the middle part on one limit of mousing-hook rotates to be arranged on and unreels on support, and this is outlying is connected with the piston rod rotation of the first cylinder from the one end on another limit.
The piston rod of cylinder is connected with mousing-hook, driving mousing-hook rotates, mousing-hook rotates down, spool is caught on the limit at its free end place, preventing spool from coming off in the first U-lag, two limits of the mousing-hook of L-shaped are straight flange, when spool to be taken off, it is easier to turn on, makes spool be difficult to the phenomenon taken off without occurring to catch on spool due to mousing-hook.
As further improvement of the utility model, also include unreeling correction underframe and Deviation rectifier, unreeling and be provided with line slideway on correction underframe, the bottom unreeling support is provided with the slide block matched with line slideway, and Deviation rectifier is arranged on and unreels on correction underframe and be connected with unreeling support.
Deviation rectifier drives and unreels support and move on correction underframe unreeling, and adjusts the position of spool, conveniently unreel follow-up in process to film surface.
As further improvement of the utility model, also include to be held up, by the second U-lag, the air-expanding shaft delivering in the first U-lag.
Air-expanding shaft prevents in the reel of spool, it is simple to plays material wall and lifts spool, rises in material wall has been lifted air-expanding shaft and air-expanding shaft is placed on the first U-lag and i.e. completes to be placed on unreeling structure the film of rolling.
As further improvement of the utility model, also include air-expanding shaft transmission clutch mechanism, air-expanding shaft transmission clutch mechanism includes being arranged on the clutch support unreeled on support, it is arranged on the brake on clutch support, rotate and be arranged on clutch support the air-expanding shaft gear being connected with brake, it is enclosed within air-expanding shaft gear and meshed internal gear, the second cylinder being arranged on clutch support and push-pull bar, the two ends of push-pull bar piston rod rotation with clutch support and the second cylinder respectively is connected, push-pull bar is connected with internal gear and this junction point is between the two-end-point of push-pull bar, one end of air-expanding shaft is provided with the brake gear can being meshed with internal gear.
This utility model arranges brake, tension force is provided to spool, rotating shaft is needed when stopping operating, to play the effect of braking, second cylinder piston elongation, promotion push-pull bar rotates, push-pull bar promotes internal gear towards the side's motion near brake gear, until being meshed with brake gear, realize the braking (i.e. realizing the braking of spool) to air-expanding shaft, the piston rod of the second cylinder shrinks, push-pull bar moves to the direction away from brake gear, internal gear is pulled to the direction away from brake gear until internal gear is disengaged from brake gear, the brake force of air-expanding shaft disappears, air-expanding shaft can realize rotating.
As further improvement of the utility model, the two ends of air-expanding shaft are separately installed with bearing, match with the first U-lag in the outer ring of bearing.
Bearing is installed at air-expanding shaft two ends, and from sliding friction, the friction mode between air-expanding shaft and the first U-lag is become rolling friction, reduces frictional force between the two, the more conducively rotation of air-expanding shaft.
In sum, the beneficial effects of the utility model are: solve and the film of rolling is placed in prior art on unreeling structure difficulty and places unstable technological deficiency, this utility model is by arranging air-expanding shaft transmission clutch mechanism, realize the braking during spool is unreeled, prevent spool from causing the film of rolling to scatter owing to unreeling too fast.
