Description

Paper local laminating type film cutting mechanism

Technical Field

The invention relates to printing machinery, in particular to a film cutting mechanism for a film laminating machine.

Background

At present, a full-automatic glazing machine and a film laminating machine are special printing equipment for glazing paper and plates and laminating films, and are important products for respectively glazing paper and integrating paper with plastic, so that the quality and the grade of the paper are improved. The film cutting mechanism is used for cutting films according to the requirements of paper specifications and sizes, but some paper requires that film coating is not needed at certain parts (local parts), so that the film cutting is firstly carried out, and then film coating treatment is carried out on a film coating machine. Thereby affecting the film coating efficiency of the paper and increasing the production cost.

Disclosure of Invention

The present invention is directed to overcome the above-mentioned disadvantages, and to provide a paper sheet partial film coating type film cutting mechanism capable of coating and cutting paper sheets on the same machine table as required.

The purpose of the invention is realized by the following technical scheme: the paper local film laminating type film cutting mechanism comprises a wallboard, a film placing roller and a film cutting roller, wherein a knife rest group cross rod is arranged on the wallboard and at the side edge of the film cutting roller, a plurality of knife rest groups are arranged on the knife rest group cross rod, and blades of the knife rest groups are butted with the film cutting roller; and a vent pipe is arranged on the wallboard and between the film placing roller and the cross rod of the knife rest group, and a waste film inlet corresponding to the position of the knife rest component is arranged on the vent pipe.

And a wind shielding patch is arranged on the vent pipe and at the side edge of the waste film inlet, and the bottom of the wind shielding patch is inserted into the interior of the vent pipe. The knife rest assembly comprises a left knife rest and a right knife rest which are arranged on a cross bar of the knife rest group, the blade is arranged on the inner sides of the outer end parts of the left knife rest and the right knife rest, and the left knife rest and the right knife rest are connected through an adjusting shaft and a pin. The two ends of the cross rod of the knife rest group are arranged on the knife rest group fixing seat through a rotating seat, and the rotating seat is connected with a rotating hand wheel arranged on the knife rest group fixing seat.

After the structure of the invention is adopted, the film on the film cutting roller is subjected to film cutting treatment by two blades (multiple groups can be used according to requirements) on the left tool rest and the right tool rest, the initially cut waste film is placed in the waste film inlet of the vent pipe, and the vent pipe is blown to continuously blow the cut waste film out of the other port of the vent pipe. The film after film cutting can be directly subjected to subsequent film covering treatment, so that the double effects of film cutting and film covering treatment can be realized on the same machine. The paper laminating work efficiency is high, the production cost is reduced, and the user requirements are completely met.

Detailed Description

Referring to fig. 1, 2 and 3, the paper local film-coating type film cutting mechanism applied to an automatic film coating machine of the invention comprises a wall plate 1, a film placing roller 3 and a film cutting roller 9 (and a film guiding roller 8), wherein a knife rest group cross rod 15 is arranged on the wall plate 1 and at the side edge of the film cutting roller 9, a plurality of knife rest groups 11 are arranged on the knife rest group cross rod 15, and blades 17 of the knife rest groups 11 are butted with the film cutting roller 9 (the surface thereof); a vent pipe 5 (which is arranged on the wall plate 1 through a vent pipe seat 4 and a wall plate fixing seat 2) is arranged on the wall plate 1 and between the film placing roller 3 and the knife rest group cross rod 15 (closer to the knife rest group cross rod 15), and a waste film inlet 23 corresponding to the knife rest component is arranged on the vent pipe 5. The right end part of the vent pipe is connected with a fan, and the fan blows air into the vent pipe. A wind shielding patch 6 is mounted on the vent pipe 5 at the side of the waste film inlet 23, and the bottom of the wind shielding patch is inserted into the interior of the vent pipe (about half of the diameter width of the vent pipe, as shown in fig. 3, for blocking the upper part of the gas in the vent pipe to prevent the waste film 21 from sticking to the inner wall of the waste film inlet and the vent pipe). The film cutting roller 9 is provided with a plurality of grooves, which is beneficial to the film cutting work of the blade.

The blade carrier assembly 11 comprises a left blade carrier 22 and a right blade carrier 16 which are arranged on a cross bar 15 of the blade carrier group (with a certain distance between the two), the blade 17 is arranged on the inner sides of the outer end parts of the left blade carrier 22 and the right blade carrier 16 (through a gasket 18) (the blade edge part of the blade is exposed and is butted with the surface of the film cutting roller), and the left blade carrier 22 and the right blade carrier 16 are butted through an adjusting shaft 20 and a pin 19. Two ends of the tool rest group cross rod 15 are arranged on a tool rest group fixing seat 12 (arranged on the wall plate 1) through a rotating seat 14, and the rotating seat 14 is connected with a rotating hand wheel 13 arranged on the tool rest group fixing seat 12. The left knife rest 22, the right knife rest 16, the gasket 18, the blade 17, the adjusting shaft 20 and the pins 19 form knife rest assemblies 11 (a plurality of groups), and the knife rest assemblies correspond to the positions and the number of waste film inlets on the air pipe 5. The distance between the left knife rest and the right knife rest (namely the distance between two blades on the left knife rest and the right knife rest, namely the width of the cut waste film) is adjusted by rotating the adjusting shaft, and then the pins are used for positioning; the transverse position of the tool rest component is adjusted through rotation of the rotating hand wheel, and the angle position of the tool rest component is adjusted through rotation of the rotating seat. The number of blade carrier assemblies and their position on the blade carrier set cross bar 15 can be adjusted as desired.

In operation, a film roll is placed on the unwinding roller, the unwound film is drawn through the film guiding roller(s) onto the film cutting roller, and the blade of the blade carrier assembly is placed on the film. When the film cutting roller rotates and rolls, the film cutting treatment is carried out on the film by two blades (multiple groups can be carried out according to requirements) on the left tool rest and the right tool rest, and the waste film 21 which is initially cut is manually placed in the waste film inlet of the vent pipe. The blower blows air to the vent pipe to continuously blow the cut waste film out of the other end of the vent pipe. The film after film cutting can be directly subjected to subsequent film covering treatment, so that the double effects of film cutting and film covering treatment can be realized on the same machine.
