Abstract

The utility model discloses a paper-adsorption-preventing device of a die cutting machine in an intaglio printing press production line. The device comprises an upper die cutting plate and a lower die cutting plate, and the lower end face of the upper die cutting plate is connected with a cutter plate. An elastic piece is fixedly arranged on the paper feeding direction edge and the paper discharging direction edge of the upper die cutting plate, and the other ends of the elastic pieces extend downwards to exceed the lower portion of the upper die cutting plate. The elastic pieces are fixedly arranged at the paper feeding direction edge of the upper die cutting plate, and three elastic pieces are fixedly arranged at the paper discharging direction edge of the upper die cutting plate. The elastic pieces are arranged in the vertical cut section, the upper ends and the lower ends of the elastic pieces are straight lines, the middle portions of the elastic pieces are curve lines, and the elastic pieces are arc-shaped in the vertical cut section. When the upper die cutting plate and the lower die cutting plate finish die cutting separation, the other ends of the elastic pieces extend downwards to exceed the lower portion of the upper die cutting plate, the lower ends of the elastic pieces still press the paper in the primary stage that the upper die cutting plate moves upwards, the elastic pieces loosen the paper after the upper die cutting plate moves upwards again for a distance, and the paper smoothly moves forwards. The paper-adsorption-preventing device is simple in structure, convenient to install and stable and reliable in work.

Description

Intaglio printing press production line die-cutting machine prevents the paper adsorbent equipment

Technical field

The utility model relates to intaglio printing press production line servicing unit, prevents that especially paper is adsorbed on the device on the cross cutting knife plate.

Background technology

The intaglio printing press production line generally comprises and unreels unit, print couple unit, crosscut unit and delivery unit.After printing, paper gets into the cross cutting station of crosscut unit, through the extruding of upper and lower mould cutting plate; Knife plate on the die cutting plate is divided into the size that needs with paper, in the actual production, when die cutting plate is accomplished a cross cutting; When last die cutting plate moves upward,, usually be attracted to by the paper of cross cutting on the knife plate of die cutting plate and cause the paper jam fault because electrostatic interaction and two template cuttings produce the vacuum suction effect from moment; Must shut down cleaning like this, yet when starting shooting again, carry out the picture and text alignment again; Cut operations such as position adjustment, and produce 300 above waste products, have a strong impact on the operating efficiency and the quality of intaglio printing press production line.

By on can know that above-mentioned existing intaglio printing press production line paper die-cutting apparatus on reality is used, obviously has defective and exists, and remain to be improved.

Thus, the improving of the above-mentioned defective of the utility model thoughts is that the spy concentrates on studies and cooperates repetition test, proposes a kind of reasonable in design and effectively improve the utility model of above-mentioned defective finally.

Summary of the invention

To the weak point of prior art, the utility model aims to provide a kind of intaglio printing press production line cross cutting station and prevents the paper adsorbent equipment, and after guaranteeing that paper is by cross cutting, smooth and easy moving forward do not produce and be adsorbed in phenomenon on the knife plate.

The technical scheme that the utility model adopts: a kind of intaglio printing press production line die-cutting machine prevents the paper adsorbent equipment; Comprise die cutting plate and counterdie cutting plate; Lower surface at last die cutting plate is connected with knife plate; The be fixedly connected upper surface of shell fragment, edge, die cutting plate lower surface on paper feed direction and paper delivery direction knife plate both sides respectively, the lower surface of said shell fragment extends beyond the lower surface of knife plate downwards.

Evenly to fixedly install the quantity of shell fragment be three to edge, die cutting plate lower surface on paper feed direction knife plate one side, and evenly to fixedly install the quantity of shell fragment be three to edge, die cutting plate lower surface on paper delivery direction knife plate one side.

Said shell fragment is in the sectional elevation of paper trend, and two ends are straight line up and down, and mid portion is a curve.

Said shell fragment is arc in the sectional elevation of paper trend.

After adopting said apparatus, when the upper and lower mould cutting plate carried out the printing sheets cross cutting, shell fragment received the downforce effect; Distortion is shunk, and does not influence the die cut operation of die-cutting machine, when the upper and lower mould cutting plate is accomplished the cross cutting separation; Because the other end of shell fragment extends beyond the bottom of die cutting plate downwards, so go up the starting stage that die cutting plate moves up, paper is also pushed down in the lower end of shell fragment; After last die cutting plate moved up certain distance again, shell fragment just broke away from paper, at this moment; Paper has overcome the vacuum suction effect of knife plate, and paper can move forward smoothly.

This apparatus structure is simple, and is easy for installation, and working stability is reliable.

In the accompanying drawing: die cutting plate 2 counterdie cutting plates 3 shell fragments 4 paper 5 knife plates on 1.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described further.

Embodiment 1 is like Fig. 1, shown in Figure 2, and shell fragment (3) is in paper moves towards sectional elevation, and two ends are straight line up and down, and mid portion is a curve; Die cutting plate 1 edge evenly is provided with three shell fragments 3 on paper feed direction knife plate 5 one sides, and die cutting plate 1 edge evenly is provided with three shell fragments 3 on paper delivery direction knife plate 5 one sides, and the upper surface of shell fragment 3 is fixed on die cutting plate 1 body; The lower surface of shell fragment 3 is under knife plate 5 working faces of last die cutting plate 1, and the two ends up and down of shell fragment 3 are the plane, is curved surface for conjunction plane between the upper and lower end face; Like this, shell fragment 3 just has better telescopic resilience, and the lower surface of shell fragment is used to push down paper 4; Shell fragment 3 adopts the 65Mn material; Heat treatment hardness is controlled at: HRC33-38, and shell fragment 3 just has fatigue strength preferably like this, and working life is longer relatively.

As shown in Figure 3, in embodiment 2, shell fragment 3 is arc in the sectional elevation of paper trend; Shell fragment 3 is processed more easily, and the upper end of same shell fragment 3 is used for fixing on last die cutting plate 1 body, and the lower end is used to push down paper 4; Shell fragment 3 adopts 65Mn material, HRC33-38.
