Description

The paper cutter of knife moving vertically

Technical field

The utility model belongs to the printing equipment technical field, particularly to the structural improvement of paper cutter.

Background technology

The primary structure of traditional paper cutter as shown in Figure 1 (Chemical Industry Press publish be entitled as " post-press finishing ", gold and silver river work, September calendar year 2001), comprise frame 11, rack-mounted workbench 12 is arranged on the feeder 13 on the workbench, paper-weight 14, the cutter bed of drive unit and drive thereof is installed in the paper knife 15 on the cutter bed; Wherein drive unit is driven the cutter bed by connecting rod and is made banking motion by the worm and gear transmission of hydraulic clutch control, makes blade tilt to cut.Feeder both can push paper forward, and the rule that can be used as the location is again used; Paper-weight compresses the paper 10 of location, occur to move in the time of can avoiding the blade incision and causes error.So the paper cutter of this structure must have just right platen power, the little sideslip of power, power is damaged paper greatly by pressure, mode of operation is: staff is delivered to pile the back of blade, though installed the relay of with the hands controlling simultaneously now additional, the measure of prevention such as infrared ray electric control structure injury accident, but still the danger of cutting away finger is arranged.Main is necessary platen, so size must have certain limitation behind the cutter, so the accuracy of last cutter of finished product still relies on technical level of operators, inaccessible final unified specification requirement fully.In addition, the razor steel blade of this paper knife 15 divides generally about 70mm, and utilizes the adjusting of link-type may not make the best use of everything.

The utility model content

The purpose of this utility model is for overcoming the weak point of prior art, design a kind of paper cutter of knife moving vertically, can guarantee that paper cutter cuts precision, prevent the generation of injury accident fully, and the length that can effectively utilize the steel blade of blade to divide.

The paper cutter of a kind of knife moving vertically of the utility model design, comprise support, workbench and be installed in feeder on the workbench, motor and lead-screw drive mechanism, cut paper knife rest and blade mounted thereto, it is characterized in that, said support is by front column, back timber and rear column constitute, said workbench is the air cushion workbench, these air cushion workbench both sides are provided with side-stop, said feeder comprises the push-and-pull cardboard, in this push-and-pull cardboard inboard a plurality of vacuum slots spaced apart and a plurality of vacuum cup are housed, and with each vacuum slot, the vacuum negative pressure device that vacuum cup links to each other; Said motor and lead-screw drive mechanism are made up of motor, leading screw, nut, guide plate and two slide blocks, and this leading screw one end is installed on the rear column at air cushion workbench bottom centre place, and the other end of this leading screw links to each other with motor; Nut on the leading screw links to each other with guide plate; Two slide block sets and link to each other with the two ends of guide plate and push-and-pull cardboard simultaneously on two side-stops; This back timber is equipped with the electric hydaulic cylinder that drives the knife rest vertical up-or-down movement, and said cut paper knife rest links to each other with the electric hydaulic cylinder below back timber.

The utility model also comprises a hyperbar device and valve island, and this hyperbar device is connected with said vacuum cup by the valve island, valve island realization vacuum cup from low pressure to anticyclonic conversion.

The utility model paper cutter main feature:

Paper cutter is vertically cut by electric hydaulic cylinder control blade.Can deduct paper-weight, feeder is servo or stepper motor by programmable controller controls, makes feeder reach the repetitive positioning accuracy of 0.01mm by lead-screw drive mechanism.And have a vacuum slot, vacuum cup.Staff can leave paper away from blade about 200-300mm before cutter, allow feeder be close to pile, inhales and goes the paper intermediate air, holds pile with vacuum cup again, and paper is dragged to correct position.(reduced friction owing to install air cushion additional, made it to become possibility.) change high pressure again into and blow out the paper hair up to having cut out last cutter, because the paper cause of fluctuation that does not have traditional paper-weight fast lifting to cause helps guaranteeing the unification of specification.Have the precision of cutting height, effectively utilize the length of blade, can prevent the advantage of injury accident fully.

The specific embodiment

The paper cutter embodiment of a kind of knife moving vertically of the utility model design is described with reference to the accompanying drawings as follows;

The general structure of present embodiment as shown in Figure 2, shown in the figure is to cut open the left side structure of showing along the vertical axis of symmetry of paper cutter, the right half part structure is symmetrical fully.Present embodiment comprises frame 20, air cushion workbench 21 and is installed in feeder 22, motor and lead-screw drive mechanism 23, cutter bed system 24 and blade mounted thereto on the workbench.Above-mentioned each parts are described in detail as follows respectively:

The rack construction of present embodiment as shown in Figure 3, comprise the framework that constitutes by back timber 201 and two root posts 202 that link to each other with its two ends, be installed in the fronk rack plate 203 on two root posts 202 and be installed in motor bearing 204 on fronk rack plate 203 bottom surfaces, after-poppet is made of the rear carrier plate 206 of rear column 205 and end fixed thereon.
