Description
Technical field
The utility model relates to equipment for making film technical field, in particular to a kind of film winding/unwinding device.
Background technique
The first step for producing protective film is to unreel, and coiled film is placed on feeding roller, then pulls film to allow thin
Film roll rotation.But the drum diameter of film roll is variation during unreeling, the variation of diameter can cause membrane tension
Variation.Tension is too small, leads to film relaxation corrugation, horizontally can also wander off.Overtension leads to film stretching transition,
It will appear tension lines on longitudinal direction, will appear the rib of protuberance on the surface of film roll, or even deformation of thin membrane can be made to be broken.Cause
This, during unreeling, to guarantee the efficiency of production and the surface quality of film, the tension kept constant is very necessary
's.And the sided corona treatment of film is also particularly significant, can carry out again sided corona treatment during cutting in the prior art, time-consuming
Arduously.
Utility model content
In view of the deficienciess of the prior art, the main purpose of the utility model is to provide one kind, and film to be enabled to receive
Constant tension is kept during unreeling and can carry out the winding/unwinding device of film corona processing simultaneously.
To achieve the above object, the utility model provides following technical solution：A kind of film winding/unwinding device, including branch
Frame and the let off roll and wind-up roll being arranged on bracket, the let off roll are connected with magnetic powder tension braker, the wind-up roll
Including roll body and the rubber layer on roll body surface is set, pressure sensor is provided between the rubber layer and roll body, it is described
Magnetic powder tension controller and pressure sensor are connected with the controller being arranged on bracket, and the side of the wind-up roll is provided with
Corona machine.
Preferably, sliding rail is provided on the bracket, the corona machine sliding setting on the slide rail, is set on the corona machine
It is equipped with the fastening screw for being fixedly connected with sliding rail.
Preferably, protective cover is provided on the corona machine.
Preferably, radiator is provided on the magnetic powder tension braker.
The utility model has the following advantages compared with the prior art, a kind of film winding/unwinding device of the utility model,
It is characterized in that incuding the pressure change on wind-up roll by pressure sensor, then adjust by controller during retractable volume
Magnetic powder tension braker comes so that let off roll is able to maintain the constant of tension during unreeling, so that film is in the winding that is completed
After can enough guarantee surfacing and constant tension, and film directly can be subjected to sided corona treatment in winding so that
The surface roughness of film can be handled disposably, and retractable volume and corona are effectively combined, and can be avoided secondary
It unreels, it is time saving and energy saving.Wherein pressure sensor setting enables to pressure sensor electric between roll body and rubber layer
Airsick breakdown, rubber layer play the role of shielding protection.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of film winding/unwinding device of the utility model.
In figure：1, bracket；2, let off roll；3, wind-up roll；4, magnetic powder tension braker；5, rubber layer；6, pressure sensor；
7, controller；8, corona machine；9, sliding rail；10, fastening screw；11, radiator.
Specific embodiment

Rubber layer 5, be provided with pressure sensor 6 between the rubber layer 5 and roll body, the magnetic powder tension controller and pressure pass
Sensor 6 is connected with the controller 7 being arranged on bracket 1, and the side of the wind-up roll 3 is provided with corona machine 8.
A kind of film winding/unwinding device of the utility model, it is characterized in that passing through pressure sensor 6 during retractable volume
Incude the pressure change on wind-up roll 3, then magnetic powder tension braker 4 is adjusted come so that let off roll 2 was being unreeled by controller 7
The constant of tension is able to maintain in journey, so that film can enough guarantee surfacing and constant tension after the winding that is completed,
And film directly can be subjected to sided corona treatment in winding, the surface roughness of film is disposably located
Reason, retractable volume and corona are effectively combined, can be avoided it is secondary unreel, it is time saving and energy saving.Wherein pressure sensor 6 is arranged
Pressure sensor 6 is enabled to not punctured by corona machine 8 between roll body and rubber layer 5, rubber layer 5 plays shielding protection work
With.
Preferably, sliding rail 9 is provided on the bracket 1, the sliding of corona machine 8 is arranged on sliding rail 9, the corona machine
The fastening screw 10 for being fixedly connected with sliding rail 9 is provided on 8.Setting can carry out effective according to the width of film in this way
The range that can act on of corona machine 8 is adjusted, enables film and 8 perfect cooperation of corona machine, adjusts and fixed form is simple
Directly, facilitate operation.
Preferably, protective cover is provided on the corona machine 8.Protective cover can protect corona machine 8.
Preferably, radiator 11 is provided on the magnetic powder tension braker 4.Radiator 11 can be by magnetic powder tensioner brake
The heat that device 4 generates when working timely distributes, and guarantees that magnetic powder tension braker 4 can work normally.
The above is only the preferred embodiment of the utility model, and the protection scope of the utility model is not limited merely to
Above-described embodiment, technical solution belonging to the idea of the present invention belong to the protection scope of the utility model.It should refer to
