Abstract

The invention relates to the field of the pulp and paper industry and serves to connect the paper webs of two rolls while continuously feeding it into a corrugated cardboard line. The invention improves the reliability of the design of the device. The device includes mechanisms for cutting 21 and clamping the blade 22 mounted on the lever 20, and the clamping bar 25 having a common drive 24. The lever with the drive stem is connected and made with the slot 32 pivotally to change the length of the shoulder when it is rotated. 4 il.

Description

LL3.Z

The invention relates to devices for joining paper webs in installations for continuously unwinding rolls and is used in the pulp and paper industry.

The purpose of the invention is to increase the reliability of the device.

FIG. 1 shows an installation for unwinding rolls, general view; in fig. 2 - carriage before splicing the sheets; in fig. 3 -

In the production line of the corrugated cardboard, the web 6 of the roll 4 is rolled up from the roll holder 2. For splicing with it, the new roll 5 is mounted on the roll holder 5, the carriage 11 is retracted to the extreme position, the web 7 of the roll 5 is loaded and on its edge t double-sided adhesive tape. Then the carriage 11 is returned to the working position. After the roll 4 has been used up, its web 6 is stopped, and the splicing

the same at the time of the splicing of the paintings; 10 is produced by the operation of the carriage 10. The drive 24 of FIG. 4 is a section A-A in FIG. 2. pulls the rod 23, which moves

the presser bar 25 and the lever 20. The presser bar 25 presses the old web 6 onto the new 7 and they are joined by the sticky

The installation for unwinding rolls includes roll 1 with roll holder 2 and 3 and rolls 4 and 5, from which unwind

canvases 6 and 7 of paper. The compound canvases 6 15 tapes. At the same time, the elastic element 22 and 7 is produced by the device for crushing the old web 6 onto the bond 17, and

the knife 21, the entrance to the slot made in connection 17 cuts off the remainder. Then the actuator 24 moves the rod 23 back, clamping

strap 25 loose stapled old

Vani cloths of two rolls, which consists of guides 8 and 9 and carriages 10 and 11 gluing. The spliced web 12 passes through the acceleration mechanism 13, enters the canvas stock accumulator 14, and 20 and the new web, the elastic element 22, after it goes into the production line, awaits the old web.

The spliced web 12 is accelerated by the acceleration mechanism 13 and the roll 5 is unwound. The carriage 10 is then moved to the outermost corrugated board. Each carriage 10 or 11 gluing includes a frame consisting of cheeks 15 and links 16 and 17, in which paper-carrying rollers 18 and 19 are installed, lever 20, position and operations are repeated on which the cutter knife 21 and elastic element are fixed 22 (rubber) blade clamping mechanism. The lever 20 is pivotally connected to the rod 23 of the actuator 24.

The clamp bar 25 is connected to the stem.

Invention Formula A device for splicing two rolls of cloths comprising guides from carriages 23 by means of a bolt 26 and a hinge axis 27. Zoka equipped with paper-rolling valleys. Rollers 28 and gears 29 are mounted on cheeks 15 of carriages 10 and 11, resting on guides 8 and 9. Rotate the carriage 10 or 11 around the axis of the hinge 27 is prevented with the aid of the crackers 30 and the stops 31. Kami, the clamping bar mounted on the carriage with the possibility of reciprocating movement, a lever with the mechanism of cutting and clamping the blade and a power drive, characterized in that, in order to increase the length of the arm of the lever 20 and position 35 of the reliability of operation, the lever with the axle mechanism hinge when turning the front cut and clamping the blade is installed This is a slot 32, a carriage made on the torcene, and has in common with the clamping lever 20 along its axis. plate drive, while the lever is connected to The device operates as follows by machining the drive rod pivotally and is made with with the possibility of changing its length. In the production line of the corrugated cardboard, the web 6 of the roll 4 is unwound from the roll holder 2. For splicing with it, a new roll 5 is installed on the roll holder 3, the carriage 11 is retracted to its extreme position, the web 7 of the roll 5 is tucked in and a double-sided adhesive tape is applied on its edge. Then the carriage 11 is returned to the working position. After the roll 4 has been used up, its web 6 is stopped, and the splicing produced by the operation of the carriage 10. The actuator 24 extends the rod 23, which moves the presser bar 25 and the lever 20. The presser bar 25 presses the old web 6 onto the new 7 and they are joined by the sticky taped. At the same time, the elastic element 22 fixes the old canvas 6 on the link 17, and the knife 21, the entrance to the slot made in connection 17 cuts off the remainder. Then the actuator 24 moves the rod 23 back, clamping strap 25 loose stapled old and the new web, the resilient element 22, releases the old web. Position and operation are repeated. Invention Formula A device for splicing two rolls of cloths, comprising guides with carriages equipped with paper-driven rollers, a pressure bar mounted on the carriage with the possibility of reciprocating movement, a lever with a cutting mechanism and a web clamping, and a power actuator, characterized in that, with the aim of increasing the cross-section 4 oo S 27 25 11
