SU1286351A1 - Apparatus for transverse cutting of strip stock - Google Patents

Abstract

The invention relates to the processing of materials by pressure and can be used to cut a strip of polymeric material. The purpose of the invention is to improve the quality of the products obtained. The strip material 26 is fed through the receiving tray 11 to the rotating drum 2. As the drum 2 rotates, the thrust ball of the knife head 3 slides along the guide 9. When the stop ball moves away from the guide 9, the knife 4 presses the material to the drum surface under the action of a spring. Further, the sub-support lever enters the guide 10 and the cutting process begins. The ball then again interacts with the guide 9 and raises the knife. The lever touches the anvil 6 and rotates by 90 °, making it possible for the workpiece to be removed by the puller 12. 1C. f-ly, 3 ill.

The invention relates to pressure material processing and can be used to cut a strip of polymeric material.

The purpose of the invention is to improve the quality of the resulting blanks.

FIG. 1 shows a device for transverse cutting of a strip material, an oblique view; in fig. 2 - knife head of the device; in fig. 3 is a view A of FIG. 1. A device for transverse cutting of a strip material consists of a frame 1 on which a drum 2 is mounted in bearings with the possibility to rotate the prices with the knife heads 3 supports fixed on it, the knives 4 of which have the ability to rotate around the axis from stops 5 and 6, to be strictly oriented fixed concentric guides 7 and 8 and shifting along the axis as a result of contact with fixed eccentric guides 9 and 10. For receiving the strip material, a receiving tray 11 is provided, and for removing the cut GOVERNMENTAL preforms --- puller 12.

The knife head consists of a lever 14 fixed on the axis 13 with screws 15 for adjusting the position of the knife 4, guide sleeves 16 installed in the covers 17 of the housing 18, springs 19 and 20, the finger 21 with the bearing 22 at its end, the thrust plate 23 supported by nut 24. In order to protect the knives from the polka, the inserts 25 are inserted into the grooves made on the drum;

The operation of the device for transverse cutting of the strip material is carried out as follows.

The strip material 26 is guided through the receiving tray I 1 to the outer surface of the floating drum 2, while the thrust niapHK 23 of the knife head 3 slides along the eccentric guide 9. With a further movement of the lever 14 of the knife head 3 touches the sliding support 5 and the swinging arm. at an angle of 90 °. In this case, the knife 4 is positioned strictly perpendicular to the STRIPE) material 26 due to the fixed concentric guide 7 and the primer; 1 max over the pit as a result of contact and 1 pair 23 of the eccentric rail 9 when the obstinate wax 23 descends from the eccentric

|; a | equal to 9, the knife 4 under the action of the rod 19 presses the strip material to the surface of the drum. Next, the bearing 22 enters the eccentric guide 10 and the fire 4, rotating with the drum 2, begins a gradual plunging into the strip material 26. After the descent of the guide 22 from the supporting surface of the eccentric guide 10 p. 23, the piston enters into 1 stroke on the eccentric guide 9 and lifts the knife 4, at which point the cut of the cut falls. The next moment the lever 14 touches the stop 6 and turns again at an angle of 90 °. The knife 4 leaves the sphere of rotation of the drum 2, making it possible in the case of sticking to the drum of the workpiece to remove its detachment. 12. Further movement takes place in a fixedly fixed concentric direction Jup1, her 8 with the raised knife head 3 as a result of contact of the ball 23 with the eccentric guide 9. This occurs before the initial position. In the following, the cycle repeats.
