Description

in fig. 3 - section bb pa fig. 2; in fig. 4 shows a section B-B in FIG. 2

The device includes: floating decoiler 1; loading trolley 2; a device 3 for removing the underrun, located at the side opposite to the movement of the strip during the operation of the unit; a driver 4 for feeding the front end of the strip from the unwinder 1; cutting device 5 for lateral strip separation.

The unit includes: frame 6, disc shears and edging shears 8. Edge shears 8 are installed along the vertical axis of movement of the strip so that their cutting head is at the floor level and is freely accessible. In front of the scissors 7, on the frame 6, there is a drive deflecting roller 9 and a pressure roller 10 having the ability to rotate around the axis 9 by 90 ° in the direction of feed of the strip, and after the disc shears 7 on the frame 6 there are rollers 11, tension regulator 12 with the possibility slight movement under the tension of the bands during its adjustment. To the left and to the right of the cutting unit, a winder 13 is installed with the possibility of independent unloading of the coils to the service side, and deflecting rollers 14, stabilizing the angle of coverage of the rollers 11.

A unit for dividing and feeding the strips is located between the tension regulator rollers 11 and the deflection rollers 14 at the winders. It includes two drive rollers 15 mounted on the frame 6 of the cutting unit; Two hinged wiring 16 with idle gland rollers 17, pressing the strips to the drive rollers 15. Swing axes 18 of the wiring 16 are mounted on bearings 19 inside the hollow rollers 11 of the tension adjusters with a gap.

Each wiring has, on one side, comb-shaped guides 20, adjustable in the transverse direction. The guides 20 are continuations of the lines 16, intersect the vertical line of movement of the strips with a minimum gap between them and the rollers 11 and are directed alternately between one line 16 to one side and the other to the other. The number of comb guides 2 and their location correspond to the number of lanes transported.

In the lower part of the wiring 16, opposite to the comb-side guides, transversely adjustable guide lines 21, centering the strips before pressing them to the drive rollers 15 located above the level of movement of the strip during unit operation, are fixed.

The raising and lowering of the wiring 16 is done by hydraulic cylinders 22.

The unloading of rolls from the drums of the coilers 13 is carried out by trolleys 23 or colliders of the coilers.

The device works as follows.

Rolls to be processed are served

unwinder pa 1 and secured to its

the drum. Device 3 removes the underride,

and the strip is set in the rollers 9 and 10 by the device 4. The rollers 9 and 10 capture the strip and guide the disc shears 7, which spread the strip to the required number of narrow strips, and the edges of the heads: the vertical edges formed at the same time to the crushing shears 8.

After the disc shears 7, the strips are fed between the rollers 11 of the tension adjuster 12 and move downward, onto the comb-shaped guide 20 located opposite the strips. Guides 20 open the strips from the vertical direction, dividing them into two streams: even in one direction, odd in the other. The strips are fed along ridges 16 to idle rollers 17 and are centered by rulers 21, after which the hydraulic cylinders 22 lift lines 16 to the upper position (shown in Fig. 1 by thin lines), pressing the strip with idle rollers

17 to the drive rollers 15. With the aid of the rollers 15, the strips through the deflecting rollers 14 are fed to the drums of the winders 13.

After that, the feeding of the strip is stopped and the edges are filled into the edging shears 8 and the strips on the drums of the winders 13. Then the wires 16 are lowered down, the required tension controlled by the regulators 12 is set on the winders 13, and the device is accelerated to operating speed.

When the device is operating, the rollers 15 and the wiring 16 do not touch the strip. The strips in the area of the disc shears 7 move vertically and the cut edges are fed without deviation into

edging scissors 8.

After the end of the roll cutting, the end of the strip is cut by the cutting device 5. The remainder of the strip is cut with disc shears 7 and wound by the winders 13, the rolls are wrapped and removed by the body 23. The inner underwind is wound onto the unwinder I reel and set again into the device 3 to remove the undershot. Thereafter, a new coil is installed on the decoiler 1, and the operating cycle is repeated.

Formula invented by

A strip slitting machine containing a cutting unit with disc and

edging scissors, between which are located the hollow rollers of the belt tension regulators, the winders placed to the left and right of the block, the unit for dividing and feeding the strips and deflecting rollers,

located at the winders, characterized in that, in order to improve the conditions of separation and supply the hollow to the winder: y1, reduce the size of the device and improve the conditions for servicing it, the node for separation

and feed rasiolsen strips between rollers

tension regulators and deflecting rollers at the winders and is made in vnde two drive rollers mounted on the frame of the cutting unit, and two articulated wiring with idle base rollers, the swing axis of the wiring located inside the hollow rollers of tension regulators with a gap, In this way, each wiring on one side is provided with transversely mounted, wiring, which is warranted, serving to continue the wiring and directed alternately on one wiring to one and the other in the process of the semopolis side; on the other hand, in the transverse direction, in the transverse direction, the direction of the direction of
