Abstract
The utility model relates to the technical field of the thin-film unreeling, absorbing and towing device, especially relates to a thin-film unreeling, absorbing and towing device, comprising an absorbing roller mounted on a supporting body, hollow roller axles communicated with an inner cavity of the absorbing roller and respectively arranged on the two ends of the absorbing roller, wherein the hollow roller axles are communicated with an air inlet of a ventilation device, a plurality of screen pores are uniformly distributed on the surface of the absorbing roller and communicated with the inner cavity of the absorbing roller. During the use process, the thin film on the unreeling device is output in turn by a plurality of absorbing rollers, the front, back surfaces of the thin film respectively pass through the surfaces of the absorbing rollers, the two ends of the inner cavity of each absorbing roller is subject to ventilation at same air rate by the ventilation device, thus the front, back surfaces of the thin film passing through each absorbing roller are absorbed on the surface of each absorbing roller by the air pressure difference, the rotation speed of the ventilation device is adjusted and the size of the absorbing force is adjusted, therefore the stable intension required by the coating technology is obtained. The front, back surfaces of the thin film passing through the surface of the absorbing roller are cleaned.
Description
Technical field:
The utility model relates to a kind of packaging film feeding device, refers in particular to a kind of film and unreels the absorption draw gear.
Background technology:
General in the market coated substrate all is film coil (like films such as PET, PI, PP, paper); And manufacturer's major part all is the different suppliers' of outsourcing a film coil; Because supplier's production technology is not quite similar; The Tension Control condition is also different when the cutting and rewinding film, thereby causes the residual internal stress of film tight ness rating and the film of rolling inconsistent, adds in addition in the process of transportation more or less can some external factor cause film rolling ectonexine tight ness rating inconsistent.Be directed to this; So the producer that current thin film uses adopts sensitive tension control system to stablize the tension force that unreels when unreeling; But still exist the unwinding tension fluctuation bigger; Cause having influence on homogeneity and internal stress inconsistent of coating, thereby quality and technology stability are affected, and then can't satisfy the demand in market.
Be directed to this, so the applicant develops the utility model.
The utility model content:
The utility model technical matters to be solved is to provide a kind of film to unreel the absorption draw gear exactly.
For solving the problems of the technologies described above; The utility model has adopted following technical scheme: this film unreels the absorption draw gear and comprises the adsorption roller that is installed on the supporting body; The two ends of said adsorption roller are respectively equipped with the hollow roll shaft that is communicated with the adsorption roller inner chamber; Said hollow roll shaft is communicated with the ventilation inlet of extractor fan, and the surface of said adsorption roller is evenly distributed with several sieve apertures, and sieve aperture is communicated with the adsorption roller inner chamber.
In the technique scheme, described adsorption roller is stainless steel rider.
Or in the technique scheme, described adsorption roller is an alloy roller.
In the use; Film on the unwinding device is exported through several adsorption rollers successively, when the pros and cons of film passes through each adsorption roller surperficial respectively, air suctiton ventilator with each adsorption roller inner chamber two ends according to same air quantity exhausting; The pros and cons of the film of feasible each adsorption roller of process is adsorbed on the surface of each adsorption roller through draught head; Regulate the rotating speed of air suctiton ventilator, can regulate the size of adsorption affinity, thereby reach the stable tension force of coating process requirement; Meanwhile, can the pros and cons through the adsorption roller surface film be cleaned.
Description of drawings:
Fig. 1 is the utility model lateral plan.
Nomenclature:
1 adsorption roller
11 sieve apertures
2 hollow roll shafts
The specific embodiment:
Below in conjunction with specific embodiment the utility model is further described.
With reference to shown in Figure 1, present embodiment the utility model comprises: be installed on the adsorption roller 1 on the supporting body.This adsorption roller 1 is the stainless steel rider of a hollow.The two ends of this adsorption roller 1 are respectively equipped with the hollow roll shaft 2 that is communicated with adsorption roller 1 inner chamber, and this hollow roll shaft 2 is communicated with the ventilation inlet of extractor fan, and the extractor fan in the present embodiment is an air suctiton ventilator.The surface of this adsorption roller 1 is evenly distributed with several sieve apertures 11, and wherein, these sieve apertures 11 are communicated with adsorption roller 1 inner chamber respectively.
In the use; Film on the unwinding device is exported through several adsorption rollers 1 successively, and when the pros and cons of film passed through each adsorption roller 1 surperficial respectively, air suctiton ventilator was taken each same air quantity in adsorption roller 1 inner chamber two ends away; The pros and cons of the film of feasible each adsorption roller 1 of process is adsorbed on the surface of each adsorption roller 1 through draught head; Regulate the rotating speed of air suctiton ventilator, can regulate the size of adsorption affinity, thereby reach the stable tension force of coating process requirement; Meanwhile, can the pros and cons through adsorption roller 1 surface film be cleaned.
Certainly, above-mentioned adsorption roller 1 also can be alloy roller.
Certainly; The above is the utility model instance only, is not to limit the utility model practical range, so; All equivalences of doing according to the described structure of the utility model claim, characteristic and principle change or modify, and all should be included in the utility model claim.
