Abstract

The utility model relates to a paper transporting device for web horizontal cutting machine, which is characterized in that: multiple rows of pores are opened on a working table; an air chamber is arranged under the working table; the air can be exhausted by an air exhauster; the paper is attached to the working table; and a blast apparatus is arranged at the pressure roller at front of the cutting knife, and an air curtain spray device is arranged between a feeding roller and a guide roller. Thus, the utility model solves the problem of the surface scratching of the painted film materials such as winding papers in the course of the transmission on the horizontal cutting machine.

Description

The paper transport device of paper in reel transverse cutting unit

Technical field

The utility model relates to a kind of paper transport device of paper in reel transverse cutting unit.

Background technology

Existing paper in reel (comprise paper in reel, reel metallic paper, reel plastic film, reel is compound or shifts multiple laser film material etc.) transverse cutting unit, no matter be hob type or cut-off knife formula, when cross cutting, paper must be pushed down paper in course of conveying, in order to cutting.Devices such as most at present employing pressure roller are pushed down paper.But these devices can produce tangible cut to the surface of paper in reel in the paper sheet delivery process, thereby have a strong impact on the surface quality of paper and so on membraneous material.Fig. 1 represents the structural principle scheme drawing of the transverse cutting unit of existing band cut-off knife.

As shown in Figure 1, the surface is clamped toward direction of arrow feeding by feeding roller 2 through the paper in reel 1 of coated, and pressure roller 3 floats, paper is depressed, with the deposit cutoff length, again by deflector roll 4, work top 6, is pushed down paper, in order to cutting the pressure roller of work top (or hairbrush) 5,7, pressure roller 9.Fixed length feeding roller 8 is delivered to paper and is cut the position, and upper cutter 11 down moves.During through lower cutter 10 paper is cut off, 12 is paper collecting table.

Cut in the process whole, be coated with 5 places that have that complex surface contacts with paper as can be seen from Figure 1, first place is feeding roller 2 places, and this feeding roller is a rubber rollers, because of fricton-tight phenomenon, thereby the surface is not had scuffing in the conveyance of sheets process.Second place is that pressure roller 3, the three places are that pressure roller (or hairbrush) 5,7, the 5th place are pressure roller 9, and this three is in paper when cutting knife 10 directions are moved, and all has the slide relative phenomenon, thereby the coverlay (as radium-shine face) that is coated with of paper is scratched.Is fixed length feeding roller 8 places everywhere, and its effect is identical with feeding roller 2, because of no slide relative, and can be with surface tear.

Summary of the invention

The defective that the paper that exists for the paper transport device that overcomes existing paper in reel transverse cutting unit is scratched in transport process, the utility model provides a kind of paper transport device of later-model paper in reel transverse cutting unit.The defective that this feedway can avoid paper to be scratched in course of conveying.

The technical scheme that the utility model adopted is: open many row's apertures on the work top between deflector roll and the fixed length feeding roller, divide into air chamber, use pumping with exhaust blower, when the film of paper and so on through out-of-date, it is adsorbed on the work top, catch in order to fixed length feeding and photocell eye and cut sign, pressure roller place in cutting knife the place ahead, blowing device is set, when the upper cutter up-and-down movement, prevents from paper is taken up in order to cutting.

Owing to adopted technique scheme, thereby avoided pressure roller and paper to be coated with the direct contact of coverlay, solve the problem of membraneous material surface tear in the crosscut course of conveying of paper in reel through coated and so on, had design science, advantage such as rational in infrastructure, practical.

Description of drawings

Fig. 1 is the structural principle scheme drawing of background technology paper in reel transverse cutting unit paper transport device.

Fig. 2 is the structural principle scheme drawing of a kind of embodiment of the utility model.

The specific embodiment

In the embodiment shown in Figure 2, this paper transport device comprises paper in reel 1, feeding roller 2, deflector roll 4, fixed length feeding roller 8, pressure roller 9, lower cutter 10, upper cutter 11 and work top 6, have many row's apertures on the work top 6, divide into air chamber, use pumping with exhaust blower, with paper and so on thin film adsorbs on work top, at pressure roller 9 places, blowing device is set, prevents that paper is taken up when cutting.Present embodiment also between feeding roller 2 and deflector roll 4, is provided with gas curtain jetting system 13, by air-flow paper is depressed, and cuts with deposit, and has overcome the defective that prior art adopts the pressure roller that floats to exist.

Claims (2)

1, a kind of paper transport device of paper in reel transverse cutting unit, comprise paper in reel (1), feeding roller (2), deflector roll (4), fixed length material roller (8), pressure roller (9), lower cutter (10), upper cutter (11) and work top (6), it is characterized in that having on the work top (6) many row's apertures, divide into air chamber, locate to be provided with blowing device at pressure roller (9).

2, the paper transport device of paper in reel transverse cutting unit according to claim 1 is characterized in that between feeding roller (2) and the deflector roll (4) gas curtain jetting system (13) being set also.
