Embodiment 4
Shown in Fig. 8, Fig. 9, between printing component and rolling assembly, it is additionally provided with transmission tension stabilizing device 51；Tension stability fills
Put 51 and include cross bar 511；Cross bar 511 is fixed a roller shutter 512；Thin film passes through below roller shutter 512；Roller shutter 512
The supplied materials end of the thin film below low side and film contacts, and roller shutter 512 and the low side going material end to be above roller shutter 512；Roller shutter 512
One layer of anti-static device 31 (not shown) of covering, anti-static device 31 can be wet cloth, i.e. on the surface of roller shutter 512
Fixing one layer of cloth, and ensure its humidity, certainly, the tightness of this layer of cloth can not affect the rolling performance of roller shutter 512.
The roller shutter 512 that the present invention provides can be bed-mat for summer, or other have rolling performance and have the parts of certain deadweight.
As shown in Figure 10, Figure 11, Figure 12, rolling assembly includes at least one hold down gag 61 and rolling rotating shaft 62, and rolling turns
Receipts are had to have film rolling 63 on axle,.Hold down gag 61 includes the first cross bar 611, depression bar 612；First cross bar 611 turns higher than rolling
Axle 62 and be parallel to rolling rotating shaft 62, the first cross bar 611 is in the supplied materials side of rolling rotating shaft 62.Depression bar 612 rotates fixing
On the first cross bar 611；Depression bar 612 is fixed with pinch roller 613 away from one end of the first cross bar 611；The rotating shaft of pinch roller 613 and
The rotating shaft of depression bar 612 is all parallel with rolling rotating shaft 62.Pinch roller 613 and film rolling 63 upper surface.
Depression bar 612 and first fixing one end of cross bar 611 have horizontal through hole；Depression bar 612 is socketed in first by horizontal through hole
On cross bar 611, and by limiting section 614, depression bar 612 is carried out the spacing of horizontal direction；Limiting section 614 is locknut；
The position being in depression bar 612 both sides on the first cross bar 611 uses locknut by spacing for depression bar 612 respectively；Hold down gag 61
It is in the lower section of the first cross bar 611, is additionally provided with the second cross bar 615；Second cross bar 615 is parallel with the first cross bar 611；In pressure
The upper surface of one end that bar 612 contacts with the first cross bar 611 fixes a lever 6121；Lever is vertical and depression bar 612.When described
Holding down assembly when turning over, pin 6121 is spacing by described second cross bar 615.
By arranging steady bubble frame moving up and down, and the baffle plate of adjustable horizontal direction distance is set on steady bubble frame, it is achieved
The film bubble of differing heights and diameter is carried out stable and spacing；By guide pillar and horizontal screw bolt, light realization steady bubble frame and baffle plate
Mobile, easy to operate simply；
In order to coordinate the various sizes of steady bubble frame of adaptation, two flanks of man-like shelf that the present invention provides also may move, thus realize right
The film bubble of different-diameter extrudes；
Fixing one on jockey pulley and moisten cloth, when thin film passes through between cloth and jockey pulley, moistening cloth can be the most anti-
Only thin film because of with jockey pulley friction and play electrostatic, it is to avoid film surface absorption dust and batting, raising film quality；
Fix a suction pipe on scraper plate by inclination, be aided with sucking pump, make the ink scraped off enter smoothly in suction pipe, it is to avoid work
The pollution of environment；
The decorative pattern that thin film has just stamped, is susceptible to drench ink or by next tension force roller mill flower, so the present invention have also been devised one-level and dries
Equipment for drying, i.e. ajutage are fixed on scraper plate, air port face toward stamp part, conveying lower temperature, relatively low custom warm braw to print
Flower carries out one-level drying, and wind direction is tilted slightly upward, it is to avoid drench ink and mill flower；
In order to make in wrapup procedure, thin film is constantly in tensioning state, so, between printing component very rolling assembly, also set
Having put one roller shutter, when membrane tension is excessive, thin film is by exceptionally straight thus rolled by roller shutter, when roller shutter is rolled onto to a certain degree,
Or membrane tension inadequate time, due to the deadweight of roller shutter, can free-falling, thin film is pressed by dropping process, so that it is guaranteed that rolling
Required tension force, it is ensured that the compactness of film rolling；Certainly, in order to avoid electrostatic, the present invention is also in the surface configuration one layer of roller shutter
Wet cloth；
In order to make film rolling more tight, the present invention is also provided with hold down gag, by rotating hold down gag, along with thin film
Volume radius is increasing, and film rolling is suppressed during lifting, made the thin film in wrapup procedure by depression bar slowly lifting all the time
Volume will not become loose because tension force is not enough；
And on depression bar, it is provided with pin, and when resting, depression bar is turned over, under the cooperation of pin and the second cross bar,
Make to hold down assembly and be in level, do not affect miscellaneous part operating；
Thin film, after one-level is dried, is not completely dried, does not the most drench ink, do not grinds flower, so also needing to through two grades of drying；
Two grades of drying that the present invention provides are warm braw dehydrator, arrange many jockey pulleys, make thin film motion road in casing in casing
Footpath becomes, and dries more thorough.
The ultimate principle of the present invention, principal character and advantages of the present invention have more than been shown and described.The technical staff of the industry
It should be appreciated that the present invention is not restricted to the described embodiments, the simply present invention's described in above-described embodiment and description is former
