As preferably, described frame is connected with described bearing arrangement by locking mechanism, and described bearing arrangement comprises two deep groove ball bearings that use in pairs, and its inner ring and air-expanding shaft end fix, and its outer ring fixes with annular lasso respectively; Described locking mechanism comprises the base being mounted with in frame, be hinged on half pressure ring on described base, described base top and half pressure ring bottom are processed with level to manhole, described lasso is assemblied in described annular through-hole, the end of described base is hinged with tie down screw, described half pressure ring outer end is designed with lock opening, and described tie down screw can rotate in the lock opening of described half pressure ring and by nut, lasso is fixed in the manhole between half pressure ring and base.
The beneficial effects of the utility model are: this protective film unwinding device assembles protective film to be produced by air-expanding shaft and rolls up; by described electromagnetic power brake and transmission gear, spragging gear, described air-expanding shaft is braked, thus the maintenance of tension force while realizing the output of protective film volume.This apparatus structure is simple, during use, protective film volume is enclosed within on air-expanding shaft, then by high-pressure gas circuit, air-expanding shaft surface gas bar is released, and protective film volume is fixed.This device is locked convenient and swift, changes film volume speed faster.
Accompanying drawing explanation
Fig. 1 is the plan structure figure of this film volume reforming unit.
Fig. 2 is the side direction structural representation of this film volume reforming unit.
The specific embodiment
Below in conjunction with embodiment, the utility model is further illustrated:
As shown in embodiment in Fig. 1 and Fig. 2, this protective film unwinding device, it comprises frame 1, and is assemblied in air-expanding shaft 2, transmission gear 3, spragging gear 4, electromagnetic power brake 5 in frame 1; Assemble with frame 1 mutually by the bearing arrangement 6 being fixedly connected with respectively at the two ends of described air-expanding shaft 2, the end of one end of described air-expanding shaft 2 is fixedly connected with described transmission gear 3, described spragging gear 4 is in transmission connection with described electromagnetic power brake 5, and described transmission gear 3 adopts gear transmission to be connected with described spragging gear 4.This device needs to have high-pressure gas circuit in factory building while using, and described air-expanding shaft 2 is connected with gas circuit, by high pressure gas, controls stretching out and retraction of the surperficial gas bar of air-expanding shaft 2.Specifically as long as use air gun just can complete facing to the valve inflation on air-expanding shaft 2, withstand outside parts (such as circular web-like base part or material), in the time of need loosening paper discharging, with hand, press the outside parts of cunning on valve, the gas bar on air-expanding shaft 2 surfaces just can be retracted, easy to use.
This protective film unwinding device is by air-expanding shaft 2 assemblings protective film volume 9 to be produced; by described electromagnetic power brake 5 and transmission gear 3,4 pairs of described air-expanding shafts 2 of spragging gear, brake; thereby the maintenance of tension force while realizing 9 output of protective film volume; make protective film volume 9 can emit protective film by pulsation-free, the quality while having improved multiple film.This apparatus structure is simple; during use; protective film volume 9 is enclosed within on air-expanding shaft 2; then by high-pressure gas circuit, the surperficial gas bar of air-expanding shaft 2 is released; the protective film using during production is rolled up the 9 raw materials inner cardboard volume that adopts conventionally; protective film with web-like from level to level be wrapped in outside, the surperficial gas bar of described air-expanding shaft 2 is released, and just protective film volume can be fixed.This device is locked convenient and swift, changes film volume speed faster.Can effectively improve the efficiency that multiple film is produced.
The fixing concrete structure of this above air-expanding shaft 2 of protective film unwinding device as depicted in figs. 1 and 2, described frame 1 is connected with described bearing arrangement 6 by locking mechanism 7, described bearing arrangement 6 comprises two deep groove ball bearings 61 that use in pairs, its inner ring and air-expanding shaft 2 ends fix, and its outer ring fixes with annular lasso 62 respectively; Described locking mechanism 7 comprises the base 71 being mounted with in frame 1, be hinged on half pressure ring 72 on described base 71, described base 71 tops and half pressure ring 72 bottoms are processed with level to manhole, described lasso 62 is assemblied in described annular through-hole, the end of described base 71 is hinged with tie down screw 73, described half pressure ring 72 outer ends are designed with lock opening, and described tie down screw 73 can rotate in the lock opening of described half pressure ring 72 and by nut 8, lasso 62 is fixed in the manhole between half pressure ring 72 and base 71.
This device need to guarantee that the diameter of described lasso 62 outer walls is less than or equal to the diameter of described air-expanding shaft 2 when part is selected in concrete manufacture.Described like this protective film volume 9 is just free to be enclosed within described air-expanding shaft 2 inflatable parts.This device in use; if described protective film volume 9 is finished using; only two nuts 8 at described air-expanding shaft 2 two ends just need be twisted off respectively and described tie down screw 73 outwards can be broken into two with one's hands; then described half pressure ring 72 rotation is opened, at this moment just can by described air-expanding shaft 2, the bearing arrangement 6 together with two ends takes off easily.Then only need to be by the outside parts of cunning of pressing on air-expanding shaft 2 valves, the gas bar on air-expanding shaft 2 surfaces just can be retracted; The inside paper roll of the described protective film volume 9 using can be taken out, and then according to above contrary step, new protective film volume 9 is contained in to air-expanding shaft 2.This change of lap mode is succinctly quick.During concrete use, also can use two air-expanding shafts 2, during one of them work, another just installs new protective film volume 9, in the time of need to changing like this, only new protective film volume 9 directly need to be loaded onto together with air-expanding shaft 2, quicker.
