The specific embodiment
Below, by reference to the accompanying drawings and the specific embodiment, the utility model is described further:
As shown in Figure 1, 2, be a kind of screen painting paper feeder of the utility model, it comprises frame 1, be arranged on the feeding-in roll 2 on frame 1 and be arranged on frame 1 and top has the bellows 4 of opening, the width of the upper opening of bellows 4 is suitable with the width of printing paper, feeding-in roll 2 is installed on frame 1 and extends along the Width of frame 1, is equipped with one and is used for driving the motor that feeding-in roll 2 rotates on frame 1.One punching component 5 also is installed on frame 1, and punching component 5 and feeding-in roll 2 lay respectively at the both sides, top of bellows 4 openings.
Referring to Fig. 3, feeding-in roll 2 is used for providing the power of printer paper conveying, and during the part of printer paper between feeding-in roll 2 and punching component 5 hung down into bellows 4, bellows 4 can provide a negative pressure, printer paper is applied a downward application force, the paper of printer paper is played tension.referring to Fig. 2, bellows 4 comprise the biside plate 42 that lays respectively at its both sides, lay respectively at its two ends and be fixed on two end plates 41 on frame 1, and the base plate 43 that is positioned at its bottom, biside plate 42, two end plates 41 and base plate 43 surround the chamber resettling of a upper opening, offer a breather port (not shown) on base plate 43, the lower surface of base plate 43 is equipped with an induced draft fan (not shown) that is positioned at disposed at air vent, after induced draft fan starts, make biside plate 42, two end plates 41, the enclosure space pressure that base plate 43 and printer paper surround reduces, in the constant situation of printer paper upper pressure, mineralization pressure is poor in the both sides of printer paper, printer paper is applied downward thrust, thereby printer paper is played tension.
Can also be by changing the width of bellows 4, to be applicable to the printer paper of different in width, concrete is, bellows 4 also comprise at least two pilot bars 44 that extend along its Width (being the Width of frame 1), the two ends of pilot bar 44 are separately fixed on frame 1, biside plate 42 is all to be arranged on pilot bar 44 by linear bearing 46, and biside plate 42 can be extended along the Width of bellows 4, guarantees that the both sides of printer paper are adjacent to respectively the madial wall of biside plate 42.In addition, for the ease of regulating the width of bellows 4, the one adjusting screw mandrel 45 parallel with pilot bar 44 also is installed on bellows 4, be fixed with respectively the feed screw nut's (not shown) of regulating on screw mandrel 45 that is sleeved on of a coupling on biside plate 42, utilize an actuating unit to drive and regulate screw mandrel 45 rotations, can by feed screw nut and the matching relationship of regulating screw mandrel 45, adjust accurately the distance between biside plate 42.
