The adjustment structure for adjusting 35 distance of adjacent cutting assembly is both provided on bar 26 and second crossbar 27；26 side of first crossbar
It is additionally provided with for film refrigeration and smooth refrigeration flat configuration；It is set gradually between cutting mechanism 6 and rolling-up mechanism 7 useful
In the anti-roll heating roller 8 in film tape edge and can by cutting after the adjacent films item slitting block 9 that interlocks separated, slitting block 9 and plus
Hot-rolling 8 is installed in rack 1.In the implementation case, heating roller 8 is driven by stand-by motor three and is rotated.
The operation principle of the present invention is such:Film to be cut is arranged to feeding roller 2, then film is in rolling-up mechanism
Under 7 drive, rolling-up mechanism 7 pulls film, is pulled through from cutting assembly 35, makes film slitting.Adjustment structure can make cutting group
Distance is more accurate between part 35.Refrigeration flat configuration can improve the brittleness of film, make to generate generation largely in cutting
Heat makes film edge plucking or curling；, and pass through 7 splitting winding of rolling-up mechanism.
Film tape adjacent after cutting is staggered by slitting block 9, facilitates winding；Heating roller 8 can plate film, make thin
Film item will not crimp.The invention has the characteristics that good cutting effect.
Specifically, 3 surface of extension roller offers the extension line to be extended by middle part phase both ends.Extension line can allow film extending
Roller 3 is pullled out, make film will not fold together.
Specifically, ceramic heating pipe 10 is installed in heating roller 8,8 top of heating roller is provided with compression roller 11, compression roller 11
It can lean with heating roller 8, compression roller 11 is arranged by an interim adjustment structure in rack 1, and interim adjustment structure includes sliding

Equipped with bayonet one that is several equidistant alternate and being connected with hole 1, it can block on bayonet one and set shim 1, shim one
Hole 1 can be separated into several thin film channels one by 24；In the implementation case, it is that a hole 1 is total that bayonet one, which opens up length,
Long 3/4ths.Offer bayonet two that is several equidistant alternate and being connected with hole 2 23 on slitting block 9, energy on bayonet two
Card sets shim 2 25, and hole 2 23 can be separated into several thin film channels two by shim 2 25；In the implementation case, bayonet
Two open up 3/4ths that length is 2 23 overall length of a hole.Thin film channel one is staggered with about two thin film channels.According to thin
Shim 1 is sequentially clamped in bayonet one, forms corresponding thin film channel one, shim 2 25 is blocked successively by the width of film item
Card inlet two forms corresponding thin film channel two.The width of reel is more than the width of film, if all reels are arranged in
On one winding bar, then the width that all reels are added is much larger than the overall width of film, so needing in advance to hand over film
Mistake separates, and the winding of film is needed after guarantee.
Prolonged cutting, causes 35 temperature rise of cutting assembly, cutting edge rust, cutting effect to become, and passes through push rod electricity
Machine 28 drives first crossbar 26 to move up and down, and first crossbar 26 drives 35 component of cutting assembly to move up and down, and makes cutting part one
Straight variation, the temperature that cutting assembly 35 is effectively ensured will not be especially high, improves the service life of cutting assembly 35.In cutting assembly
35 settings are when in first crossbar 26 and second crossbar 27, by rotating handwheel 34, first crossbar 26 and second crossbar 27 manually
