Trimming is carried out, the film roll compacted is wound and turned into after trimming.
Why film roll can reach after winding compacts, and is substantially derived from mutually tightening between each position of plastic foil
Caused tension force, mentioned strain certainly based on the circumferential tension force of film roll, but the tension force on film roll axial direction also function to it is certain
Booster action.
However, the most edge at left and right sides of film roll, due to its outside, there is no plastic foil（Such as in film roll
It is left along position, there is no film roll in its left side）, thus compared with other positions, the tension force that film roll edge is subject to is relatively small,
In particular by axial tensile force very little, make at left and right sides of film that edge position tensioning degree is more relatively low, cause winding
Film roll easily shows slightly fluffy at edge position.After existing film trimming, because edge is neat, therefore with the Winding Layer of film roll 9
Increase, it is fluffy the problem of build up, until there is the problem of similar quick-fried muscle at the edge position of film roll 9（As in Fig. 1 AB
Position shown in CD）.
Certainly, with the difference of the factors such as film roll material, plastics film thickness, winding tension, film roll Winding Layer, this side
It is also different along the order of severity of quick-fried muscle problem.
Utility model content
The purpose of this utility model is to overcome disadvantages mentioned above and provide a kind of mounting structure of plastic sheeting trimming blade,
It can make lateral attitude of the film side along partially thick point spread out, and reduce the degree of the quick-fried muscle in edge, and can according to film roll material,
The degree of scatter of the partially thick point of the factors such as plastics film thickness, winding tension, film roll Winding Layer regulation.
Its purpose can be realized by following scheme：The mounting structure of the plastic sheeting trimming blade include frame, Cutter apron,
Cutting edge, cutting edge are fixedly mounted on Cutter apron, it is characterised in that horizontal line slide rail is also fixed with frame, it is described
Cutter apron laterally slidably can be arranged on horizontal line slide rail；The Cutter apron is connected with transverse link, the end of transverse link
End is hinged with drive link；Motor is also equipped with frame, machine shaft is fixedly connected with slider bearing, and slider bearing turns with motor
Axle synchronous axial system, sliding block is installed with can radially sliding in slider bearing, sliding block is fixedly connected with eccentric shaft；In slider bearing
Also twist-on limited location bolt, the end of caging bolt press sliding block respectively；Excentric sleeve, excentric sleeve are provided with around eccentric shaft
Bearing is provided between eccentric shaft；Excentric sleeve is fixedly connected with the drive link.
Also twist-on has two caging bolts in slider bearing, and two caging bolts are located at the opposite sides of sliding block respectively,
The end of two caging bolts presses sliding block respectively.
In present specification, ＂ that so-called sliding block can radially slide is radially ", refer to the radial direction of machine shaft.
The utility model has advantages below and effect：
First, during utility model works, eccentric shaft moves in a circle around machine shaft, moving radius and eccentric shaft phase
It is identical for the offset of machine shaft；In the process, the central axis of excentric sleeve keeps the central axis with eccentric shaft
It is overlapping, and excentric sleeve drives Cutter apron and cutting edge periodic reverse transverse movement by drive link, transverse link, so as to not
Change the lateral attitude of cutting knife disconnectedly, thus the lateral attitude on periodically-varied film side edge, make film side edge（Partially thick point）Edge
Spread out, accumulation will not be concentrated in same lateral attitude, therefore it is thick significantly to weaken accumulation of the film side along partially thick point
Degree, film side edge quick-fried muscle phenomenon caused by thickness point is concentrated is substantially eliminated, improves winding quality,
2nd, the offset of two caging bolt adjusting sliders and eccentric shaft can be utilized, and then adjusts cutting edge periodically
The amplitude of reciprocating transverse movement, i.e. regulation make degree of scatter of the film side along partially thick point, to adapt to film roll material, plastics thickness
The requirement of the factors such as degree, winding tension, film roll Winding Layer change.Under special circumstances, eccentric shaft can be adjusted to electricity
Machine rotating shaft is in same central line, and the offset for making eccentric shaft is zero, then the width of cutting edge periodic reverse transverse movement
Degree is that zero, now drive link and transverse link are motionless, the working condition of cutting edge and the cutting knife working condition of traditional trimming mechanism
It is identical.
