Description

A kind of up-coiler and barrier film cutting knife thereof

Technical field

This utility model relates to up-coiler field, particularly relates to a kind of up-coiler and barrier film cutting knife thereof.

Background technology

The barrier film cutting knife of existing up-coiler, is substantially the flat cutter of employing, and in actual use, uses Flat cutter direct shearing barrier film, impulsive force is big, resistance is big, shearing is difficult, cause cutting barrier film easily stretchable, become Shape, and easily band grain raising；Especially ceramic diaphragm, in the case of cutting knife uses the time longer, easily generates heat And reduce the precision that material volume is sheared.

Utility model content

For solving above-mentioned technical problem, the utility model proposes a kind of up-coiler and barrier film cutting knife thereof, it is possible to reduce Burr so that the trimming of barrier film is smooth, and improve the precision that material volume is sheared.

For reaching above-mentioned purpose, this utility model by the following technical solutions:

The utility model discloses the barrier film cutting knife of a kind of up-coiler, including handle of a knife and blade, described blade is arranged In the side of described handle of a knife, wherein said blade includes multiple tooth mouths that the height being connected continuously does not waits, Duo Gesuo State tooth mouth and be v-shaped structure.

Preferably, multiple described tooth mouths include high tooth that multiple height is equal and the equal low tooth of multiple height.

Preferably, multiple described high teeth and multiple described low tooth are spaced with equivalent amount respectively.

Preferably, multiple described high teeth and multiple described low tooth are spaced one by one.

Preferably, described handle of a knife is square structure.

Preferably, described handle of a knife connecting setting and adds heat pipe, described heating pipe is for described handle of a knife and described cutter Sword heats.

The invention also discloses a kind of up-coiler, it is characterised in that include above-described barrier film cutting knife.

Compared with prior art, the beneficial effects of the utility model are: the barrier film of up-coiler of the present utility model The blade of cutting knife uses the multiple V-arrangement tooth mouths not waited so that during shearing barrier film, the most relatively High tooth mouth mainly undertakes shearing work, and the most relatively low tooth mouth mainly undertakes smoothing work, thus reduces shearing During burr on barrier film so that the trimming of barrier film is smooth, improves the precision that material volume is sheared；Meanwhile, Contact point is less relative to flat cutter and common zigzag cutting knife, and resistance reduces further, blade the most easy to wear, makes Stage teeth of the present utility model barrier film cutting knife relative to flat cutter and common zigzag cutting knife service life more Long.

In further scheme, multiple tooth mouths only comprise the tooth mouth of two kinds of height, the most of a relatively high height Tooth and the relatively low low tooth of height, and high tooth and low tooth are spaced with equivalent amount, between being preferably the most one by one Every arrangement, on the one hand make barrier film cutting knife shearing force during shearing barrier film steady, on the other hand also enhance The shearing function of barrier film cutting knife and smoothing function so that the burr of shearing reduces further, the trimming of barrier film is more Smooth, and improve the precision that material volume is sheared further.

In further scheme, handle of a knife is also connected be provided with adding heat pipe, add heat pipe can to handle of a knife and Blade heats, and goes for shearing ceramic diaphragm, improves the precision that ceramic diaphragm is sheared.

Accompanying drawing explanation

Fig. 1 is the structural representation of the barrier film cutting knife of the up-coiler of this utility model preferred embodiment.

Detailed description of the invention

Below against accompanying drawing and combine preferred embodiment the utility model is described in further detail.

As it is shown in figure 1, be the structural representation of the barrier film cutting knife of a kind of up-coiler of this utility model preferred embodiment Figure, barrier film cutting knife includes handle of a knife 1 and blade 2, wherein: blade 2 is arranged on the side of handle of a knife 1, blade 2 Including high tooth 21 and low tooth 22, the highest tooth 21 and low tooth 22 are all v-shaped structures, and high tooth 21 is relatively low The height of tooth 22 is higher, and high tooth 21 and low tooth 22 are spaced one by one, during shearing barrier film, high Tooth 21 mainly undertakes shearing work, and low tooth 22 mainly undertakes smoothing work, to reduce in shear history septation Burr so that the trimming of barrier film is smooth, and improve material volume shear precision；Handle of a knife 1 is square structure, cutter Handle 1 is provided with installation position 11, is used for connecting installation on the winder, additionally can also connect on handle of a knife 1 Setting adds heat pipe (not shown), adds heat pipe (not shown) and can be used to carry out handle of a knife 1 and blade 2 Heating, goes for shearing ceramic diaphragm, improves the precision that ceramic diaphragm is sheared.

In certain embodiments, blade 2 can also be include multiple tooth mouths that the height being connected continuously does not waits； In further embodiments, high tooth 21 and low tooth 22 on blade 2 can be spaced with equivalent amount respectively, As 2 high teeth 21 connect 2 low teeth 22, reconnect 2 high teeth 21, the like formed and be continuously connected High tooth 21 and low tooth 22.

The barrier film cutting knife of above-described embodiment both may be used for cold cut, it is also possible to for fervent, is all to be driven by cylinder Drive mechanism is operated, and wherein heats barrier film cutting knife by adding heat pipe, may be used for ceramic diaphragm Shearing, it is possible to solve barrier film cutting knife burr is many, precision is low problem.

Preferred embodiment of the present utility model also discloses a kind of up-coiler, this up-coiler include foregoing description every Film cutting knife.

Above content is to combine concrete preferred implementation further detailed description of the utility model, It cannot be assumed that of the present utility model being embodied as is confined to these explanations.Technology belonging to this utility model is led For the technical staff in territory, without departing from the concept of the premise utility, it is also possible to make some equivalents and replace Generation or substantially modification, and performance or purposes are identical, all should be considered as belonging to protection domain of the present utility model.
