Description

A kind of device of cutting dashed line

[technical field]

The utility model relates to a kind of device of cutting the dashed line between each continuous bag on the plastic bag.

[background technology]

People generally adopt packaging bag in the daily life.Can make the form of a plurality of bags of connections in the packaging bag bag process, and between adjacent sack, cut necessary easily openable line, so that the user is torn by hand.

Yet the existing device of cutting dashed line generally is plastics of pad or a bakelite plate below bag, selects the milling cutter of different in width then again by junction width requirement between the polybag.Add man-hour, direct collision was to following plate after milling cutter was cut the broken bag body, and like this, the dashed line that difference is required will be with different cutting knifes, and often will change following backing plate; Behind the tangent line, bag also can hang on the cutting knife sometimes, breaks easily when bag send before continuation during bag, brings a lot of inconvenience to processing.

[utility model content]

The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of and has satisfied different disconnections and be connected needs, and can prevent that the tangent line back pkt. from hanging over the device of cutting dashed line on the cutter.

In order to solve the technical problem of above-mentioned existence, the utility model adopts following technical proposals:

A kind of device of cutting dashed line includes workbench, it is characterized in that fixedly being equipped with on the described workbench backing plate, backing plate has the slit, slit top is provided with the blade that can insert in it, and being equipped with above workbench can upper and lower mobile knife rest, and described blade is fixedly mounted on the knife rest;

Aforesaid a kind of device of cutting dashed line is characterized in that described blade is one group and distributes and point of a knife small blade down by line, and small blade is fastened on the knife rest with screw;

Aforesaid a kind of device of cutting dashed line is characterized in that being equipped with on the described knife rest movable guide rod, and movable guide rod shaft is set with the compression spring outward; Below described blade, but the bag pressing plate of a concora crush on described backing plate is housed on the movable guide rod, has the saturating groove that passes for above-mentioned blade on the bag pressing plate;

Aforesaid a kind of device of cutting dashed line is characterized in that also being provided with a blade pressuring plate on the described knife rest, and described blade tightly is locked in the knife rest lower end by screw;

Aforesaid a kind of device of cutting dashed line it is characterized in that also being screwed with on the knife rest adjusting bolt of its dropping distance of control, but this is regulated bolt lower end roof pressure on described workbench;

Aforesaid a kind of device of cutting dashed line is characterized in that described workbench top is provided with cylinder, and described knife rest is fixedly mounted on the piston rod of cylinder.

The beneficial effects of the utility model are:

1, adopt the market blade of cutting a sheet of paper commonly used, it is divided into small blade by line, the small blade point of a knife is contained on the knife rest down, with pressing plate with blade pressing.Driving blade with cylinder moves downward, a backing plate that has seam is arranged below bag, when blade moves downward, bag pressing plate contacts with bag earlier, and bag pressing plate is pushed down bag under spring action, and blade just inserted the slit of backing plate when blade continued to move downward, the blade place of switching to disconnects, do not switch to the place and connect, can repeatedly process and need not to change backing plate, convenient and practical;

2, the setting height(from bottom) that can regulate pressing plate by the adjusting bolt, thus the degree of depth of control blade incision satisfies different disconnections and is connected needs;

When 3, blade moved upward under cylinder drives, bag pressing plate made bag take off from the blade cutter head under spring action, can not hang on the blade.

[specific embodiment]

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:

As shown in the figure, a kind of device of cutting dashed line, include workbench 1, backing plate 11 fixedly is housed on the workbench 1, have slit 110 on the backing plate 11,110 tops, slit are provided with the blade 13 that can insert in it, above workbench 1, be equipped with can upper and lower translation knife rest 12, blade 13 is fixedly mounted on the knife rest 12.In the utility model, blade 13 adopts the markets blade of cutting a sheet of paper commonly used, and blade 13 is divided into small blade by line, and small blade is distributed in order, and the point of a knife of each small blade is installed on the knife rest 12 down; Movable guide rod 14 is installed on the knife rest 12, and movable guide rod 14 shafts are set with compression spring 15 outward; Below blade 13, a bag pressing plate 16 is equipped with in movable guide rod 14 lower ends, but bag pressing plate 16 concora crush have the saturating groove 161 that passes for blade 13 on the bag pressing plate 16 on backing plate 11, and the cutter head of blade 13 is no more than the bottom surface of bag pressing plate 16 during off position.

In the utility model, workbench 1 top is provided with cylinder 10, and knife rest 12 is fixedly mounted on the piston rod of cylinder 10, and by extraneous controller control cylinder 10, cylinder 10 drives knife rest 12 and does upper and lower translation.

During work, cylinder 10 drives knife rest 12 and blade 13 moves down, bag lies between backing plate 11 and the bag pressing plate 16, and when blade 13 moved down, bag pressing plate 16 contacted with bag earlier, bag pressing plate 16 is pressed in bag on the backing plate under spring 15 effects, knife rest 12 continues to move downward with blade 13, and blade 13 just inserts the slit 110 of backing plate 11, and blade 13 places of switching to disconnect, do not switch to the place and connect, the relative together knife rest 12 with movable guide rod 14 of bag pressing plate 16 this moment upwards slides and compression spring 15.When knife rest 12 moves up under cylinder 10 drives with blade 13, compressed spring 15 make under the tension force effect bag pressing plate 16 continue to push down the bag in bag, shift out fully up to blade 13, be compressed spring 15 this moment and recover reset condition, the relative together knife rest 12 with movable guide rod 14 of bag pressing plate 16 is being got back to the home position and is being risen with knife rest 12 to lower slider, for tangent line is next time prepared.Like this, guarantee that bag can take off from blade 13 cutter heads, and can not hang on the blade 13.

For satisfying different disconnections and being connected needs, also be provided with blade penetraction depth adjusting device on the utility model knife rest 12 and cut out different striping effects to reach.Regulate bolt 19 and be screwed on the knife rest 12, adjust the position of regulating bolt 19, when the long striping of needs, to regulate bolt 19 and raise, and make knife rest 12 Bottom Runbies big, the tangent line degree of depth of blade 13 is big like this, striping is just long, and the linkage section between adjacent two stripings is just short; Otherwise, will regulate bolt 19 declines, knife rest 12 Bottom Runbies are diminished, the tangent line degree of depth of blade 13 is little like this, and striping is just short, and the linkage section between adjacent two stripings is just long, thus satisfied difference disconnects and is connected needs.
