Description

A kind of automatic winding device

Technology or application

The utility model belongs to a kind of wrap-up, relate to a kind of automechanism that can carry out rolling to paper or flexible sheet material, more specifically, be that a kind of suction function that utilizes is fitted on the rolling rotating cylinder flexible sheet material automatically, so that the automatic winding device that rotating cylinder is reeled the flexible sheet material rolling is got up.

Existing background technology

Wrap-up of the prior art before beginning to carry out rolling work, need be fixed on the flexible sheet material end on the rotating cylinder, at present, the way that people adopt has following several, and the one, stick on the end of flexible sheet material with non-drying glue, and this end is attached on the rotating cylinder; The 2nd, have notch on the rotating cylinder, this notch can be inserted in the end of flexible sheet material; The 3rd, on rotating cylinder, fix to clamp mechanism, the flexible sheet material end can be sandwiched in this mechanism.These ways all need manual operation, can't finish automatically the flexible sheet material end is fixed on the rotating cylinder.

Content of the present utility model

The purpose of this utility model is to provide a kind of suction function that utilizes to make the flexible sheet material end can be fitted in automatic winding device on the rolling rotating cylinder automatically.

The purpose of this utility model also is to provide a kind of automatic winding device with introducing mechanism, and the introducing mechanism of this automatic winding device can automatically guide flexible sheet material to enter rotating cylinder, and its end can be contacted with rotating cylinder with tangential angle.

Its purpose is realized by following proposal:

A kind of automatic winding device, comprise rotating cylinder and drive the motor that rotating cylinder rotates, its principal feature is that the rotating cylinder two ends have at least an end to be connected with depression generator, the rotating cylinder periphery is formed with some through holes, by described depression generator effect and produce negative pressure in described through hole.

In the such scheme, when rotating cylinder one end is connected with depression generator, the other end can seal, and depression generator just can produce stronger suction function in through hole like this.

Be more preferably, in the such scheme, depression generator all is equipped with at the rotating cylinder two ends, to overcome owing to only at one end be provided with to cause two ends through hole adsorption affinity to differ greatly to cause reeling and go wrong easily.

Be more preferably, in the such scheme, rotating cylinder is connected by a conical head with depression generator, and its center of this conical head also is formed with through hole, and this through hole can be passed to the suction function that connects depression generator in the rotating cylinder.

Like this, when depression generator is worked, produced negative pressure in rotating cylinder inside, this negative pressure forces air to flow into from outside to inside in the through hole of rotating cylinder periphery, when flexible sheet material just contacts with rotating cylinder, just be subjected to air effect from outside to inside, thereby flexible sheet material can automatically be fitted on the rotating cylinder periphery.

Be more preferably, in the such scheme, the rotating cylinder two ends have at least an end that the scalable closing means is housed, and this mechanism can be stretched or compressed, make be closed or open rotating cylinder part on through hole be hedged off from the outer world or be communicated with.

When closing means is stretched rotating cylinder top through hole is closed, bigger suction function is concentrated on other through holes, at this moment applicable to the less flexible sheet material of coiling width; Otherwise, when being compressed, closing means make rotating cylinder top through hole open, and suction function is extended to these through holes, at this moment applicable to the bigger flexible sheet material of coiling width.

Thus obtained automatic winding device can be regulated by the scalable closing means, is applicable to the flexible sheet material of coiling different in width.

Be more preferably, in the such scheme, install the rotating cylinder front lower place can guide the introducing mechanism of flexible sheet material near to or in contact with rotating cylinder.

Because the automatic winding device is equipped with the introducing mechanism of flexible sheet material, thereby, must be by the problem that guarantees that manually flexible sheet material end and rotating cylinder are fixing, this problem can be settled a dispute by the parties concerned themselves by introducing mechanism, thereby can realize the automation of whole process.

In the such scheme, introducing mechanism comprises the supporting plate control mechanism of a supporting plate and this supporting plate of control, and this supporting plate control mechanism can rotate or move mode is controlled supporting plate near rotating cylinder, and position flexible sheet material thereon can be contacted with rotating cylinder with tangential angle.

In order to obtain better guarantee, in the such scheme, the rotating cylinder back is equipped with the guiding mechanism that can guide flexible sheet material applying rotating cylinder.

Like this, when flexible sheet material is sent into by other machines, can be under the guiding of introducing mechanism, make its front end and rotating cylinder near to or in contact with, subsequently, can be adjacent to rotating cylinder down the auxiliary of guiding mechanism, and be subjected to suction function, under the rotating cylinder rotation, finish coiling simultaneously.

In the such scheme, guiding mechanism comprises the baffle plate control mechanism of a baffle plate and this baffle plate of control, and this baffle plate control mechanism may command baffle plate is stopped the part side of rotating cylinder near rotating cylinder, to strengthen the suction function of this part, flexible sheet material can more stably be fitted on the rotating cylinder.

Be more preferably, in the such scheme, the baffle plate side is curved, can bring up comparatively osed top space in rotating cylinder part side better, to improve the effect of strengthening negative pressure.

In the such scheme, guiding mechanism and introducing mechanism can become one, and jointly by unified control mechanism control, when this mechanism makes supporting plate near rotating cylinder, also make baffle plate near rotating cylinder part side.

Be more preferably, in the such scheme, motor-driven rotating cylinder rotation system drives conical head and drives rotating cylinder by conical head through transmission device and rotates.

Automatic winding device of the present utility model except that the above-mentioned advantage of mentioning, also has following characteristics:

1, owing to adopts depression generator in the through hole of drum surface, to produce suction function, flexible sheet material can be fitted on the rotating cylinder automatically, thereby the flexible sheet material can be got up by rolling when guaranteeing the rotating cylinder rotation, characteristics with automation, the end of flexible sheet material can not be damaged yet.

2, the setting of introducing mechanism can guarantee that the flexible sheet material end contacts with rotating cylinder with tangential angle, and flexible sheet material can more easily be attached on rotating cylinder, guarantee simultaneously flexible sheet material subsequently can be automatic accurate, be fitted on the rotating cylinder apace.

3, the introducing of scalable closing means also can overcome the difference because of the flexible sheet material width, and when the flexible sheet material of the less width of reeling, the existence of its two side through hole negative pressure may impact the location of flexible sheet material.

4, because motor-driven rotating cylinder system drives the rotating cylinder rotation through transmission device driving conical head and by conical head, by conical head the negative pressure that depression generator produces is passed in the rotating cylinder simultaneously, integral structure has characteristic of simple, the also easy and safety of the replacing of rotating cylinder operation simultaneously.
