(54) DEVICE FOR LONG-TERM ROLLING

MATERIALSV

The invention relates to cutting, and in particular, to devices for longitudinally cutting rolled materials and can be used in various industries for cutting foils, paper, films, fabrics, etc. A device for slitting roll materials is known, comprising two cutting units, one of which is in the form of circular knives, a. another in the form of razor blades fixed on a bar, a guide roller placed on the shaft and a turn actuator. The drawbacks of the device are laboriousness and a long time for changing the device 1 when switching from cutting with circular knives to cutting with blades and back. To cut razors with blades, you must perform the following operations: move one of the shafts with circular knives away from the second shaft with circular knives, loosen all the circular knives alternately on the second shaft and slide them to the edges of the devices That they do not touch the passing material and does not spoil its surface, to rotate and lock in operating position the hinged timber with blades. The same operations, only in reverse order, must be performed when switching from cutting razors to cutting with circular knives and, moreover, adjustment must be made. The goal is to reduce the labor capacity and changeover of the device. The goal is achieved by the transition from cutting with discs, knives to cut-and-cut, razor blades back, the shaft is eccentric and connected with a rotation drive, and the beam with razor blades is fixed above the guide roller with an eccentric shaft. FIG. 1 shows the device,. The overall view in FIG. 2 is a section A-A w in FIG. 1, FIG. 3 is a section BB of FIG. one.

The device contains a guide roller 1 and two slitting units, one of which is made in the form of circular knives 2, 3, and the other in the form of razor blades 4, housed in holders 5, which are fixed on the bar 6. The bar 6 is rigid associated with an eccentric shaft. 7, on which a guide roller 9 is located on bearings 8. A bar 6 with razor blades 4 is positioned above the guide roller 9. An eccentric shaft 7 with a 10-turn actuator. The drive U can be manual in the form of a handwheel or mechanical, and can be driven with an eccentric shaft 7 by means of a worm gear, the wheel of which is placed on shaft 7, and the worm to 12 on the drive shaft. Circular knives 2, 3 can be located on drive or idle shafts, at least one of which is connected to the knot adjustment unit.

FIG. Figure 1 shows a cutting unit, the circular knives 2 of which are located on the drive shaft 13, and the circular knives 3 on the idler shaft 17 connected with the adjustment knock-off knives. The knot adjustment unit for the knives is made in the input bar 15, connecting the shaft 14 of the knives 3 with the shaft 16 of the guide roller 1 and the drive 17 of the rotation of the shaft 1 which is made similar to the actuator 1O. Directing the first roller 1 fixed on the bearings 8 placed on the shaft 16U

The device works as follows.

With disc knives (the position of roll material 18, disk knives 3, blades 4, nshravl in the reel roller 9.1 is shown in Fig. 1 by solid lines) the roll material 18 bends around the directions; the roller 1, prohoyit between the disk blades 2 and 3, is cut and falls onto the roll 9.

 cutting blades with razors (on Auger roll 1 of material 18, circular knives 3, blades 4, guide roller 9 is shown in Fig. 1 by dashed lines) roll: material 18 bends around the curved roller 1, not touching each other. knives, blade / razor blades 4 and fall vaEsch} ava roller 9. To change the device during the transition from cutting

DISK knives turn the shaft 16 to cut with blades and retract the shaft 14 together with the disk knives 3 from the disk knives 2. Turn the eccentric shaft 7 through a worm gear. 11, 12 rotate the bar 6. In this case, the holders of the 5 blades of the razors 4 occupy the working position, and the guide roller 9 moves in space and ensures the passage of the coiled material 18 when cutting the blades of the razors 4 c. From the knives 2. disk knives plant disk knives 3 in disk knives 2 and q turn the eccentric shaft 7, with the razor blades 4 occupying a non-operating deposit and the squeezing roller 9 will return to its original position and ensure the position of the roll material 18 in the device needed when cutting the disc knives

The design of the device reduces the laboriousness and time of its changeover when switching from cutting with circular knives to cutting with razor blades and back. The reduction of labor-intensiveness and time of readjustment of the device is achieved by installing circular knives and razor blades with the possibility of rotation. Reducing the changeover time of the 1fi transition from cutting with circular knives to cutting with blades or back will be at least 12-18 min with a width of cut roll material iOOO-lSOO mm and the number of circular knives on the shaft in the order of 8-15 cm.

Ф о рм у л and from a gain

A device for longitudinal cutting of rolled materials containing two cutting units, one of which is made in the form of a knife blade, and the other in the form of razor blades fixed on a bar, a guide roller placed on the shaft, and a turn actuator, about tons and hours This is due to the fact that, in order to reduce the labor intensity and changeover time of the device when switching from cutting with circular knives to cutting razors and back, the shaft is BEA ExaltedSHD and is connected to the headset, and the beam with razors is located along the guide , roller and rigidly connected with eccentric shaft.
