Abstract

DEVICE FOR WRINKING OF ROLL MATERIALS, containing a drive shaft with a clamping device and centered! 1 roll on the inside diameter, characterized in that, in order to simplify the design of the device, the roll clamping and centering device is designed as slidable on the hubs mounted on the drive a shaft of cheek disks with rollers having the ability to move along the rotation of the drive shaft in the figure shaped slots of the disks.

Description

1

The invention relates to devices for winding coiled materials during the processing of thermoplastics in the chemical industry and can also be used in the textile, paper and food industries.

Devices for winding web materials are known that contain a drive shaft with a device for clamping and centering the coil to the inner diameter. However, the device is complicated in construction and does not provide for centering the spool relative to the axis of the drive shaft.

The purpose of the invention is to simplify the design of the devices.

The goal is achieved by the fact that the device for clamping and centering the roll is made in the form of slip-mounted slippings on hubs mounted on the drive shaft of cheek disks with rollers. Have the ability to move along the rotation of the drive shaft in the figured grooves of the disks made along the chords.

 FIG. 1 shows the proposed device for winding a rolled material, a longitudinal section; in fig. 2 shows section A-A in FIG. one.

The device comprises a drive shaft 1, in which a device is mounted for clamping and centering the roll 2 according to its inner diameter. For the winding of the roll, a replaceable elastic pshul 3 is used. On the end of the shaft 1 there are installation cone slots, where the cone of the driven 4 and the driving 5 supports enter. On the side of the drive pole, at the end of the shaft, it is fastened according to 835552

vodka 6, through which the shaft is driven into rotation.

The device for clamping and centering the coil consists of 5 mounted disks 7 on the drive shaft 1, on the hubs of which, by way of landing, are fitted cheeks 8 with rollers 9. The disks 7 have chords shaped 10 along the chords. 10

The cheeks 8 are interconnected by the sleeves 11 passing through the grooves 12 of the discs 7. The axes of the rollers 9 are installed in the slots of the cheeks 8, which provide simultaneous rolling of the rollers and prevent the axes from tilting. The hubs of the disks 7 are attached to the hubs of the discs 7 by screws, which are inserted into the longitudinal keyway of the shaft 1. The discs 7 can be moved along the shaft 1 to adjust the width of the roll, and they are fixed by the set screws.

When the coil is being wound, rotation of the drive shaft 1 is transmitted from the driving support 5 by means of the lead 6. When the shaft 1 rotates, the cheeks 8 slip relative to the disc hubs 7, while the rollers 9 move in the shaped grooves 10 of the discs 7 towards the narrowing of the groove, jamming the slot 3. The uniform simultaneous movement of the rollers ensures that the roll is correctly centered. After the winding is finished, the roll of the drive shaft is checked in the direction opposite to its direction of rotation, the rollers roll in the direction of a larger section of the grooves, and the spool with the roll is easily removed.
