Description

one

The invention relates to the machining of polymeric materials and can be used when cutting sheet elastic materials, naturamer, elastic polyurethane foam.

A device for cutting a sheet of polymeric material includes a drive shaft with circular blades {.i}.

However, the known machine does not provide good quality cutting, because The ribbons produced by cutting can be tightened by rotating knives, causing them to jam.

It is also known a device for cutting Lithuanian polymeric materials, comprising a drive shaft mounted on a base with disk blades and pressure plates arranged between them mounted on a crush line installed parallel to the axis of rotation of the drive shaft 2,

The presence of clamping plates in the device prevents the ribbing of knives of various types by knives.

The disadvantage is that when cutting materials of different thickness clamping plates

Tiny should change. The need for plate re-adjustment arises when the width of the cutting tape is changed.

The purpose of the invention is to control the operational capabilities of the device.

This is achieved by the fact that it is provided with clamping plate holders mounted on the brace to be rotated and moved relative to it, and the clamping plates are installed in the holders with the possibility of vertical displacement.

FIG. 1 shows the view of the spur & device. di; in fig. 2 is a section A-A in FIG. 1; in fig. 3 shows a section BB in FIG. 2; in fig. 4 shows the attachment of the clamping plates.

The device consists of an axle 1 with a cobalt on which the register 2 is mounted with a register, with circular knives 3 of multifaceted shape mounted on the shaft 2 with replaceable bushings 4 and nuts S. The upper roll is made movable in a groove in the guide 7, On the drive shaft 2, between the knife blades 3, it is necessary to bend (i8), set to 1) 9, with the possibility of vertical transfer to 1, fixing them with a screw 10, the turn holders 9 are mounted on a bracket 11, the halogen HeiiHDM in B1, of the shaft parallel to the axis when Bo / iiforo the shaft 2. The holders are mounted on the bracket that can be rotated and moved relative to it. Their position on the shaft is fixed by a screw 12.

The device works as follows. The sheet elastic material 13 is fed to the disk knives 3. Making the knives in the form of a polyhedron provides, simultaneously with the sharp material, a chopping effect. The effect that BajKHO is when processing an elastic material that when crushed is crushed. During the cutting process, the material is held in place by clamping gshastins 8, then goes to the heavy rails 6, which are drawn through the finished ribbons.

Thus, in the proposed device, when measuring the thickness of the material being processed, the position of the pressure plates in the vertical and horizontal planes is controlled, and the pressing force

they are calibrated by rotation of the microchip holders.
