Refer to Fig. 1 and Fig. 2, the paper cutter longitudinally cutting delivering gear 100 in the utility model one embodiment, comprising: crossbeam 110, support (not shown) and cutting knife unit 130.
Crossbeam 110 is strip structure.Crossbeam 110 is for being set up in above paper (not shown), and paper is generally coil paper, and it can be arranged on outside paper delivery mechanism usually, and transmits with certain speed.Concrete, support is two.Two supports are arranged at the both sides of paper transverse direction respectively, and the two ends of crossbeam 110 are connected with two supports respectively, are set up in above paper to make crossbeam 110.Cutting knife unit 130 is arranged on crossbeam 110.
Cutting knife unit 130 can be multiple.Multiple cutting knife is arranged at intervals on crossbeam 110, can carry out cutting of multiple tracks longitudinal direction to make above-mentioned paper cutter longitudinally cutting delivering gear 100 to paper simultaneously.See also Fig. 3, cutting knife unit 130 comprises supporting seat 132 and cutting knife 134, and supporting seat 132 is arranged on crossbeam 110, and cutting knife 134 is arranged on supporting seat 132.
Please again consult Fig. 1 and Fig. 2, crossbeam 110 is provided with slide rail 112, slide rail 112 extends along the axis of crossbeam 110, and supporting seat 132 is slidably disposed on slide rail 112.Supporting seat 132 is arranged on slide rail 112, and to enable the position of cutting knife 134 transversely adjust at paper, and then the width of rear paper is longitudinally cut in adjustment.
At least one end and the support threaded engagement of crossbeam 110 form screw pair.Because at least one end of crossbeam 110 and support threaded engagement form screw pair, when crossbeam 110 rotates, under screw pair effect, crossbeam 110 also can move along its axis simultaneously, cutting knife unit 130 can be taken exercises in a vertical and horizontal direction simultaneously, so cutting knife unit 130 is rotated and near or away from paper.
Concrete, at least one end of crossbeam 110 is provided with threaded post 114, and threaded post 114 offers external screw thread.Support offers corresponding screwed hole (not shown), threaded post 114 and screwed hole threaded engagement.Concrete in the present embodiment, one end of crossbeam 110 and a wherein support threaded engagement, the other end is connected with another bracket slide, and the other end opposite brackets of crossbeam 110 is rotatable.
It is pointed out that threaded post 114 also can be arranged on support, and screwed hole correspondence is arranged on crossbeam 110, to meet the threaded engagement of crossbeam 110 and support.
The other end of crossbeam 110 can be provided with connecting axle 116, and support offers corresponding connecting hole (not shown), connecting axle 116 is slidably disposed in connecting hole, and the relative connecting hole of connecting axle 116 is rotatable.
Be appreciated that in other embodiments, the two ends of crossbeam 110 all can be threaded with support formation two screw pairs.Two screw pairs to screw togather direction and lead all consistent, can rotate and move axially synchronously carry out to meet crossbeam 110.
See also Fig. 4, in traditional paper cutter, its cutting knife is in feed process, need through the lower cutter of vertical direction movement and horizontal direction movement by cutter two processes, when paper transfer rate is higher, cutting knife, in lower cutter and feed process, there will be vibration when contacting with paper, make to cut quality greatly to reduce, also can damage cutting knife simultaneously.
See also Fig. 5, above-mentioned paper cutter longitudinally cutting delivering gear 100 is in feed process, rotating beam 110, move to make cutting knife 134 in the vertical direction in cutting knife unit 130, simultaneously under screw pair effect, crossbeam 110 also can move along its axis simultaneously, the lower cutter of cutting knife 134 is combined with by cutter two processes, and then in whole feed process, cutting knife 134 moves along a reversible curve, cutting knife 134 is gradually in a vertical and horizontal direction near the position that paper need cut, whole feed process is comparatively steady, decrease the vibration of cutting knife 134, substantially increase the quality cut, avoid the damage of cutting knife 134 simultaneously.
Conveniently to the rotation of crossbeam 110, above-mentioned paper cutter longitudinally cutting delivering gear 100 also comprises push rod 150, and push rod 150 is arranged on crossbeam 110.During work, operating personnel can grip push rod 150, carry out rotating beam 110, to complete the operation of feed or withdrawing.
Be appreciated that crossbeam 110 also drives by motor etc., to realize automated job, now push rod 150 can omit.
Above-mentioned crossbeam 110 also can be hollow structure, and its inside offers the cavity (not shown) for filling liquid.When specific works, the higher liquid of water isodensity can be injected in the cavity of crossbeam 110, to improve the quality of whole crossbeam 110 further, suppress the generation that cutting knife 134 vibrates.
Meanwhile, this case additionally provides a kind of paper cutter, and this paper cutter adopts above-mentioned paper cutter longitudinally cutting delivering gear 100.
Above-mentioned paper cutter longitudinally cutting delivering gear 100, in its feed process, cutting knife 134 moves along a reversible curve, cutting knife 134 is gradually in a vertical and horizontal direction near the position that paper need cut, whole feed process is comparatively steady, the less vibration of cutting knife 134, substantially increase the quality cut, avoid the damage of cutting knife 134 simultaneously.
In addition, above-mentioned cutting knife unit 130 realizes the motion on vertical direction by the rotation of crossbeam 110, relatively traditional paper cutting mechanism, above-mentioned paper cutter longitudinally cutting delivering gear 100 eliminates elements such as driving the vertical direction motor that moves up and down of cutting knife 134 and vertical direction slide rail, cutting knife unit 130 can directly be arranged on crossbeam 110, make the distance between the center of gravity of the center of gravity of cutting knife unit 130 and whole paper cutter longitudinally cutting delivering gear 100 shorter, further suppress the vibration of cutting knife unit 130 when carrying out high speed and cutting.
The above embodiment only have expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
