Abstract
The utility model discloses an adjustable paper-feeding device. The adjustable paper-feeding device includes a cross beam and a plurality of paper-feeding wheels disposed in a shell of a printer. A plurality of paper-pressing mechanisms used for balancing stress in a printing water transferring process are arranged on the cross beam. Each of the paper-pressing mechanisms includes an L-shaped body composed of a vertical face board and a transverse face board integrally. Two press boards are arranged in parallel in an inner groove of each transverse face board. An upper part of a front end of each transverse face board is provided with a blocking board limiting the press boards to lift up. Edge lugs provided with axle holes are formed on external sides of front ends of the two press boards. Two pinch rollers are installed between the edge lugs through the axle hole. The pinch rollers are pressed on the paper-feeding wheels in a connected manner and rear ends of the pinch rollers are connected to a lower end of a spring used for fine adjusting positions of the pinch rollers and the wheel-feeding wheels. The adjustable paper-feeding device provided by the utility model has beneficial effects that the stress in all directions on paper is uniform and the paper feeding process is smooth since the five paper-pressing mechanisms and the paper-feeding wheels are adopted for driving paper to move forward and the fine adjustment of pressure on the paper-feeding wheels is realized through the stretching and the contracting of the spring.
Description
Technical field
The utility model relates to a kind of textile industry printer, particularly a kind of adjustable form feeding device of printer.
Background technology
The printer that uses at present, paper advance mechanism generally be by chart motor through a cover reduction gearing, drag paper and move forward the paper feed task of finishing finally by crossing feed rollers or sprocket wheel.Between traditional lettering roller and the contact roller or space is excessive, or the lettering roller surface is too sliding, when the fabric width of printing paper strengthen by often occur printer paper-feeding inhomogeneous, walk apart from the time little when large, printer paper-feeding deflection and deflection the problem such as increase gradually.
Summary of the invention
The purpose of this utility model provide a kind of can be when printing the various printing paper of larger fabric width, printing paper is not because of the adjustable form feeding device on the textile industry printer of being suitable for of the stressed irregular problem that produces the inhomogeneous or paper feed deflection of paper feed etc.
The technical scheme that the utility model adopts is: a kind of adjustable form feeding device, the crossbeam and a plurality of paper feed wheel that comprise the transmitting device housing that is positioned on the Support for impression mechanism, be provided with a plurality of for the stressed paper-pressing mechanism of balance printing paper transmission course at described crossbeam, described paper-pressing mechanism comprises by vertical panel and the integrally formed L shaped body of transverse panel, in described transverse panel inside groove, be provided with side by side two block pressur plates, be provided with the baffle plate of restriction pressing plate raising height in described transverse panel upper front end; Each forms limit ear with axis hole the described two block pressur plate front ends outside, and the axle between the ear of both sides is equipped with two pinch rollers, described pinch roller be crimped on the paper feed wheel above; Be connected in described two block pressur plate rear ends for the lower end of fine setting pinch roller with the spring of paper feed wheel location, described spring vertically is arranged on the back side of vertical panel, and the upper end of described spring hangs on the link plate of upper end, vertical panel back side setting.
Described paper-pressing mechanism is provided with five.
The beneficial effects of the utility model are: drive paper by five paper-pressing mechanisms and paper feed wheel and advance forward, two pinch rollers are arranged again on each paper-pressing mechanism, pinch roller is through the pressing plate linking springs, finely tune the pressure of pinch roller on the paper feed wheel by the draw and shrink of spring, make the paper all directions stressed evenly, level and smooth paper advance is avoided paper break or deflection.

The specific embodiment
Below, with the specific embodiment the utility model is described in further detail by reference to the accompanying drawings.
Fig. 1 is the form feeding device schematic diagram of the adjustable form feeding device of the utility model, and Fig. 2 is the local enlarged diagram of the adjustable form feeding device of the utility model.As shown in the figure, comprise paper feed wheel 2 and the crossbeam 3 of the transmitting device housing 1 that is positioned on the Support for impression mechanism, be provided with a plurality ofly for the stressed paper-pressing mechanism 4 of balance printing paper transmission course at described crossbeam 3, described paper-pressing mechanism has five.
Referring to Fig. 3 and Fig. 4, paper-pressing mechanism 4 comprises by the integrally formed L shaped body 41 of vertical panel 46 and transverse panel 47, is provided with side by side two block pressur plates in described transverse panel inside groove, is provided with the baffle plate of restriction pressing plate raising height in described transverse panel upper front end; At described transverse panel 47 interior two block pressur plates 42 that are provided with side by side, each forms limit ear 43 with axis hole described two block pressur plates, the 42 front ends outside, and the axle between the ear of both sides is equipped with two pinch rollers 44, described pinch roller 44 be crimped on paper feed wheel 2 above; Be connected to the lower end of taking turns 2 position springs 45 for fine setting pinch roller 44 and paper feed in described two block pressur plates 42 rear ends, described spring 45 vertically is arranged on the back side of vertical panel 46, the upper end of described spring 45 hangs on the link plate 48 of upper end, vertical panel 46 back sides setting, described spring helix tube spring.
Driving paper through five paper-pressing mechanisms 4 with paper feed wheel 2 advances forward, two pinch rollers 44 are arranged again on each paper-pressing mechanism 4, pinch roller 44 is crimped on the paper feed wheel 2, each pinch roller 44 connects pressing plate 42, it is 2 stressed that the deadweight of pinch roller 44 and pressing plate 42 is taken turns paper feed, when paper feed, paper is taken turns 2 one reaction forces to paper feed, the paper feed process is smooth and easy during the whole stress equalization of paper, when the discontinuity equalization of paper a part, is subjected to the large position of resistance to force pinch roller 44 to lift, helix tube spring 45 contractions this moment, reduce the active force of pinch roller 44 on paper feed wheel 2, the height that pinch roller 44 lifts is subjected to the restriction of baffle plate 49, makes lifting that pinch roller 44 can be not unlimited.Helix tube spring 45 is adjusted the positions of pinch rollers 44 on paper feed wheel 2 by pressing plate 42, finely tunes the position of each pinch roller 44 and corresponding paper feed wheel 2 through the draw and shrink of spring, makes the paper all directions stressed even in order to avoid paper break can be drawn various paper.
It is worthy of note; protection domain of the present utility model is not limited to above-mentioned instantiation mode, according to basic fundamental design of the present utility model, as long as those of ordinary skills need not through creative work; the embodiment that can associate all belongs to protection domain of the present utility model.
