Abstract
The utility model relates to a kind of PVA inflation film manufacturing machine deflector roll, the rubber layer comprising cylindrical roll body and be coated on outside roll body, diameter in the middle part of roll body is greater than the diameter at roll body two ends, the two ends of roll body are arranged with inhibiting device respectively, inhibiting device can be fixed on roll body by latching device along roller moving, inhibiting device is made up of limiting stopper and fixed block, the fixed block of inhibiting device is near the end of roll body, inhibiting device and roll body contact site and limiting stopper are equipped with skid resistant course away from the end face of fixed block, the periphery of fixed block is provided with latching device, latching device is by bolt adjusting tightness.Cladding rubber layer on deflector roll, prevents PVA film from pulling, middle in the shape that arches upward, and PVA film can be made to be stretched to both sides by centre by during roll body, avoid appearance to fold, purse up; Inhibiting device offsets about preventing PVA film, ensures that PVA film keeps unified by direction from start to finish, and when avoiding rolling, uneven phenomenon appears in PVA film on material receiving roller.
Description
Technical field
The utility model belongs to plastic inflation film manufacturing machine field, is specifically related to a kind of PVA inflation film manufacturing machine deflector roll.
Background technology
There is following problem in existing PVA guide roller of film blowing machine: the PVA thin film thickness obtained due to just inflation and soft in blown film process, there is problem that is not parallel or distortion a little in some deflector roll, then easy plastic film to be pulled, wrinkling, what also can directly cause PVA film to be wound around on material receiving roller in addition is uneven, impact use and attractive in appearance.
Summary of the invention
The purpose of this utility model is to provide one to avoid pulling PVA film, occurring fold, ensures the PVA inflation film manufacturing machine deflector roll that the rewinding of PVA film is neat.
The utility model solves the technical scheme that its technical matters adopts: a kind of PVA inflation film manufacturing machine deflector roll, the rubber layer comprising cylindrical roll body and be coated on outside roll body, diameter in the middle part of described roll body is greater than the diameter at roll body two ends, the two ends of described roll body are arranged with inhibiting device respectively, inhibiting device can be fixed on roll body by latching device along roller moving, described inhibiting device is made up of limiting stopper and fixed block, the fixed block of inhibiting device is near the end of roll body, inhibiting device and roll body contact site and limiting stopper are equipped with skid resistant course away from the end face of fixed block, skid resistant course is that elastomeric material is made, the periphery of described fixed block is provided with latching device, latching device is by bolt adjusting tightness.
Particularly, described inhibiting device is cylindrical boss, and the diameter of limiting stopper is greater than the diameter of fixed block.
Particularly, described inhibiting device is made up of elastomeric material.
The utility model has following beneficial effect: cladding rubber layer on deflector roll, prevents PVA film from pulling, middle in the shape that arches upward, and PVA film can be made to be stretched to both sides by centre by during roll body, avoid appearance to fold, purse up; Inhibiting device offsets about preventing PVA film, ensures that PVA film keeps unified by direction from start to finish, and when avoiding rolling, uneven phenomenon appears in PVA film on material receiving roller.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the utility model limit device structure schematic diagram.
In figure, 1, roll body, 2, inhibiting device, 3, latching device, 4, rubber layer, 5, limiting stopper, 6, fixed block, 7, skid resistant course, 8, bolt.
Detailed description of the invention
By reference to the accompanying drawings the utility model is described in further detail now.
As Fig. 1, shown in Fig. 2, a kind of PVA inflation film manufacturing machine deflector roll, the rubber layer 4 comprising cylindrical roll body 1 and be coated on outside roll body 1, diameter in the middle part of described roll body 1 is greater than the diameter at roll body 1 two ends, the two ends of described roll body 1 are arranged with inhibiting device 2 respectively, inhibiting device 2 can move along roll body 1 and be fixed on roll body 1 by latching device 3, described inhibiting device 2 is made up of limiting stopper 5 and fixed block 6, the fixed block 6 of inhibiting device 2 is near the end of roll body 1, inhibiting device 2 and roll body 1 contact site and the end face of limiting stopper 5 away from fixed block 6 are equipped with skid resistant course 7, skid resistant course 7 is made for elastomeric material, the periphery of described fixed block 6 is provided with latching device 3, latching device 3 is by bolt 8 adjusting tightness.
Described inhibiting device 2 is cylindrical boss, and the diameter of limiting stopper 5 is greater than the diameter of fixed block 6.
As preferably, inhibiting device 2 is made up of elastomeric material, and namely limiting stopper 5 is one-body molded by elastomeric material with fixed block 6, can omit like this and install skid resistant course 7 in addition additional.
During use, according to the position of the width adjusting inhibiting device of PVA film, make the distance between the limiting stopper of two inhibiting device consistent with the width of PVA film, inhibiting device is fixed on roll body by the bolt then tightening latching device.In blown film process, PVA film passes through in the middle of two inhibiting device, because roll body mid diameter is greatly in the shape that arches upward, PVA film makes to be stretched to both sides by centre through roll body, thus avoid appearance to fold, purse up, in addition, inhibiting device offsets about preventing PVA film, ensure that PVA film keeps unified by direction from start to finish, when avoiding rolling there is uneven phenomenon in PVA film on material receiving roller.
The utility model is not limited to above-mentioned embodiment, and anyone should learn the structural change made under enlightenment of the present utility model, and every have identical or close technical scheme with the utility model, all falls within protection domain of the present utility model.
Technology, shape, structure part that the utility model is not described in detail are known technology.
