Abstract
The utility model relates to a printing machine, particularly a paper width adjusting device. A rotary shaft is provided with a roller according to the design proposal provided by the utility model. The roller forms an olive shape of which the middle diameter is greater than that of both ends. A movable plate is arranged on the rotary shaft. The lower end of the movable plate is connected with a U-shaped support frame of which both ends are provided with pin shafts; the pin shaft is provided with a roller. One end of the rotary wheel is connected with a rocking arm which is provided with a handle. The end of the rotary shaft is arranged on a wall plate. A section of the rotary shaft passing through the wall plate is provided with a rolling arm which is provided with an arc-shaped groove. Screws are screwed in a screw hole on the wall plate after the screws pass through the arc-shaped groove. The olive-shaped roller is used for carrying out accurate adjustment for different loosening points of paper. Therefore, the utility model has the advantages of obvious adjustment effect, convenient operation and good reliability.
Description
Technical field
The utility model relates to printing machinery, specifically a kind of device that is used to adjust paper width.
Background technology
Paper roll distortion can occur after long-time the placement, in the printing operation process, almost tight, both sides loose " fan-shaped phenomenon " in the middle of paper all can appear in each tower printing element occur overprint error thereby make up and down between each colour cell.Therefore between tower and tower the paper width adjusting device should be set.Structure commonly used is as shown in Figure 1: pressure roller 18 is cylindrical, about respectively be provided with one, paper 17 passes through in the middle of two pressure rollers 18, rotates when adjusting handwheel 19, can regulate the position of pressure roller 18.But,,, therefore can not have influence on the effect of adjustment to the degree of tightness difference corrective action power of different parts on the paper 17 to the active force equalization of paper 17 because pressure roller 18 is columniform.
Summary of the invention
The purpose of this utility model is to design a kind of paper width adjusting device, utilizes the different degrees of tightness of olivary pair of rollers paper place accurately to adjust, and it is obvious and easy to operate to adjust effect, good reliability.
According to design provided by the utility model, roller is installed in rotating shaft, this roller be shaped as the olive shape of mid diameter greater than the two ends diameter.
Movable plate is installed in rotating shaft, is connected U type support, bearing pin is installed, roller is installed on bearing pin at the two ends of U type support in the lower end of movable plate.One end of rotating shaft connects rocking arm, and handle is installed on rocking arm.The end of rotating shaft is installed on the wallboard, passes in rotating shaft on a section of wallboard rocking arm is installed, and deep-slotted chip breaker is set on rocking arm, and screw passes in the screwed hole that is screwed into behind the deep-slotted chip breaker on the wallboard.
At an end of rotating shaft connecting axle is installed, is stretched out at connecting axle on a section of wallboard rocking arm is installed.Connecting portion at rotating shaft and connecting axle is provided with notch, and the end face of rotating shaft rests on the plane of notch, and bolt passes the hole that is arranged on roller end and the notch, and rotating shaft and connecting axle are linked together.
The utility model has the advantages that: utilize one can move and be olivary roller and just can accurately adjust, and it is obvious, easy to operate to adjust effect, good reliability the different degrees of tightness of paper place.
Description of drawings
Fig. 1 is original width adjusting mechanism.
Fig. 2 is an adjustment structure chart of the present utility model.
Fig. 3 is the N-N view of Fig. 2.
Fig. 4 is that the K of Fig. 2 is to view.
The specific embodiment
As shown in the figure: roller 5 is installed in rotating shaft 1, this roller 5 be shaped as the olive shape of mid diameter greater than the two ends diameter.Utilize 5 pairs of paper 15 of this olivary roller to apply different pressure, change the situation of paper 15 middle tight both sides pines, make the width unanimity of paper 15, accurate to guarantee chromatography, improve printing quality.Among Fig. 3 16 is paper roll.
One end of rotating shaft 1 connects rocking arm 9, and handle 10 is installed on rocking arm 9.Turning handle 10 drives rotating shaft 1 by rocking arm 9 and rotates, and the olive shape roller 5 that drives again on movable plate 2 and the support 3 rotates together, with the angle of exerting pressure of 5 pairs of paper 15 of adjustment roller, thus the pressure size of 5 pairs of paper 15 of adjustment roller.
The end of rotating shaft 1 is installed on the wallboard 12, passes in rotating shaft 1 rocking arm 9 is installed on a section of wallboard 12, and deep-slotted chip breaker 20 is set on rocking arm 9, and screw 11 passes in the screwed hole that is screwed into behind the deep-slotted chip breaker 20 on the wallboard 12.Adjust exerting pressure during angle of roller 5 when needs, unclamp screw 11 earlier, rotate rocking arms 9, after adjusting to the right place, tighten screw 11 again, rocking arm 9 is fixed on the wallboard 12 by handle 10.
At an end of rotating shaft 1 connecting axle 8 is installed, is stretched out at connecting axle 8 on a section of wallboard 12 rocking arm 9 is installed.Connecting portion at rotating shaft 1 and connecting axle 8 is provided with groove 13, and the end face of rotating shaft 1 rests on the plane of groove 13, and bolt 14 passes the hole that is arranged on rotating shaft 1 end and the groove 13, and rotating shaft 1 and connecting axle 8 are linked together.Utilize this structure can make things convenient for installation and debugging.Among Fig. 26 is bearing, and 7 is back-up ring.
