Description
Technical field
The utility model belongs to film production manufacturing technology field, and in particular to a kind of contact of plastic film winding device
Roller.
Background technique
In the modern life, plastic film because function admirable, the transparency it is good, cheap, easy to use the advantages that, extensively
Applied to all trades and professions, such as product packaging, green house of vegetables.Before present plastic film production lines winding parent roll core, generally
It can change the tracking roller of position equipped with one, also referred to as contact roller, when main function is implementation contact winding or gap winding,
Film is pressed against in winding core, smooth film is gone to rapidly in core, realizes the purpose of smooth winding；Meanwhile
The air for applying film roll interlayer when certain pressure is wound with timely exclusion to parent roll by contact roller, makes film roll not fluff, prevents
Only the film crumple on parent roll or generation striped.However in wrapup procedure, film slipping phenomenon is easy to appear because deflector roll is smooth,
To causing the membrane tension in wrapup procedure uneven, and when parent roll completely roll up need to rewind when, often in new core
There is film wrinkle phenomenon, causes several hundred meters of bottom to wrinkle, this undoubtedly improves the rejection rate of plastic film, and increase is produced into
This.
Traditional method is encapsulated to deflector roll or uses other methods to increase the coefficient of friction of deflector roll, and such method needs special
Industry producer, which carries out processing to deflector roll, to complete, and when burr occurs in roller, whole roller will be replaced, not only time-consuming to take
Power, and cost is too high.
Utility model content
The utility model provides a kind of contact roller of film take-up regarding to the issue above, can effectively eliminate deflector roll skidding
Phenomenon improves film take-up quality, and the contact roller is easy to maintain, to reduce production cost, improve winding quality, improves
Economic benefit.
To achieve the above object, the utility model provides the following technical solutions:
A kind of contact roller of film take-up, including hydraulic device, guide rail, roller bearing, contact roller, the guide rail peace
On membrane production equipment, roller bearing is mounted on guide rail, and roller bearing is fixedly connected with the piston rod of hydraulic device；It is described
The cross section of guide rail is in " I " fonts, is provided with T-shape slideway on the cross section of roller bearing, the T-shape slipway clamp on guide rail,
Slide roller bearing can along guide rail under the driving of hydraulic device；
The roll body surface wrap of the contact roller has one layer of cork band, the cork band seamless company on contact roller
It connects, cork band is coated with pressure sensitive adhesive with contact roller contact on one side, winds cork band and is adhered on contact roller；
The both ends of contact roller are connect with roller bearing by bearing, and contact roller is a hollow cylinder, and contact roller is driven voller, by
The movement of parent roll contacts roller rotation to drive.
The contact roller of a kind of film take-up above-mentioned, in which: the cork band, which is from left to right spirally wound on, to be connect
It touches on roller, and is seamlessly connected between cork band.
The contact roller of a kind of film take-up above-mentioned, in which: contact roller is made of steel.Surface coats cork
Band contacts the skin-friction coefficient of roller to increase, and prevents from skidding between film and contact roller, wrinkle at the bottom of when rewinding to reduce
The generation of phenomenon improves film take-up quality；Hydraulic device makes to contact roller to film roll production by Hydraulic Cylinder roller bearing
Raw certain contact pressure, and the pressure set becoming larger and change with parent roll diameter make to contact roller and make relative to parent roll
Retrogressing moves in parallel.
Compared with prior art, the utility model has the beneficial effects that
1. the skin-friction coefficient of contact roller is improved since roller surface spiral is seamless is wound with cork band for contact, it can
It prevents from skidding between film and contact roller, so that the membrane tension produced is uniform, reduces the generation for phenomenon of wrinkling at the bottom of when rewinding, and
And cork band will not scratch film；
2. since cork is coated with special pressure sensitive adhesive with reverse side, it can directly wind and be sticked on deflector roll and deflector roll
The conventional methods such as encapsulated are compared, and the operation is more convenient, convenient for safeguarding, are greatly reduced entreprise cost, are improved the performance of enterprises.
3. so that contact roller is applied certain pressure to film parent roll using the movement of hydraulic device control contact roller, and
The pressure of setting becomes larger and changes with parent roll diameter, ensure that the uniformity of parent roll stress, to improve winding quality.
