Description
Technical field
The utility model relates to a kind of film winding machine, particularly relates to a kind of blown film retracting device.
Background technology
Inflation film manufacturing machine aborning, by the film two-fold of cylindrical shape, then deliver on tendon duct winding machine through connecting gear by herringbone clamping plate, due to, herringbone clamping plate are generally made up of many deflector rolls, before rolling, also need to flatten by with the deflector roll flattening function, present deflector roll is all generally smooth, leveling roller many employings arch rollers in the past, this arch rollers arches upward to centre gradually from the left and right sides, when plastic film is through arch rollers, can naturally stretch to both sides and reach flattening object, but the roll bending degree required when different types of plastic film flattens is different, even same volume film, because each position crease intensity is different, the best roll bending degree that each position requires is also different, if roll bending degree is too large, then may cause plastic film excessive tensile, also plastic film can be caused to pull, otherwise, if roll bending degree is too little, then flatten not in place, flatten weak effect.Meanwhile, be easy to produce electrostatic in film manufacturing processes, electrostatic also can cause film to furl unfairness.
Summary of the invention
The purpose of this utility model is just to provide one to solve the problem, and can flatten, avoid fold to film, and can avoid because electrostatic causes film roll to receive the blown film retracting device of irregular situation generation.
To achieve these goals, the technical solution adopted in the utility model is such: a kind of blown film retracting device, comprise the main shaft for stretch wrap film, be positioned at the auxiliary rotating shaft of main shaft both sides, described auxiliary rotating shaft diameter is less than main shaft diameter, main shaft, auxiliary rotating shaft is all horizontally disposed with, main shaft side is provided with the live-rollers of a pair level, described live-rollers comprises main live-rollers and from live-rollers, wherein, main live-rollers upper surface is coated with cashmere-planted layer, described cashmere-planted layer is provided with the semi-round projection of number row, described projection with the midperpendicalar of main live-rollers for axis of symmetry is symmetrical arranged, wherein, be positioned at the projection on the left of symmetric line, each arranges right low left high, it is 75 ° to 60 ° with the angle of midperpendicalar, away from the auxiliary rotating shaft of main live-rollers, be socketed with a becket, described becket upper surface is concordant with auxiliary rotating shaft, becket connects an electrostatic line.
As preferably: described projection is also provided with cashmere-planted layer.
As preferably: described electrostatic line connects a metal clamp away from one end of becket.
Compared with prior art, the utility model has the advantage of: film is before being reeled by main shaft, first through main live-rollers with from live-rollers, because main live-rollers Surface coating has cashmere-planted layer, the contact surface of it and film can be increased, add the arrangement mode of semi-round projection, during with film contacts, can to extend film as both sides, flatten film, cashmere-planted layer is soft simultaneously, film can not be damaged, becket and auxiliary rotating shaft are socketed, when auxiliary axis of rotation, becket does not rotate, becket connects an electrostatic line, can ground connection, remove the electrostatic of the film of its contact, be beneficial to better rolling.Projection is also provided with cashmere-planted layer, can better be damaged by protective film, electrostatic line is gone back connection metal clamp, can be clamped on grounded metal, very convenient.The utility model can make the film of storage avoid fold, and can avoid because electrostatic causes film roll to receive unfairness.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of main live-rollers in Fig. 1.
In figure: 1, main shaft; 2, auxiliary rotating shaft; 3, becket; 4, electrostatic line; 5, metal clamp; 6, main live-rollers; 7, from live-rollers; 8, protruding.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Embodiment 1: see Fig. 1 and Fig. 2, a kind of blown film retracting device, comprise the main shaft 1 for stretch wrap film, be positioned at the auxiliary rotating shaft 2 of main shaft 1 both sides, described auxiliary rotating shaft 2 diameter is less than main shaft 1 diameter, main shaft 1, auxiliary rotating shaft 2 is all horizontally disposed with, main shaft 1 side is provided with the live-rollers of a pair level, described live-rollers comprises main live-rollers 6 and from live-rollers 7, wherein, main live-rollers 6 upper surface is coated with cashmere-planted layer, described cashmere-planted layer is provided with number row semi-round protruding 8, described protruding 8 with the midperpendicalar of main live-rollers 6 for axis of symmetry is symmetrical arranged, wherein, be positioned at the projection 8 on the left of symmetric line, each arranges right low left high, it is 75 ° to 60 ° with the angle of midperpendicalar, in auxiliary rotating shaft 2 away from main live-rollers 6, be socketed with a becket 3, described becket 3 upper surface is concordant with auxiliary rotating shaft 2, becket 3 connects an electrostatic line 4.In the present embodiment, be also provided with cashmere-planted layer on described protruding 8, described electrostatic line 4 connects a metal clamp 5 away from one end of becket 3.
During operation, from Fig. 1, main live-rollers 6 clickwise, from live-rollers 7 left-hand revolution, transmitted to main shaft 1 by film, the hand of rotation of main shaft 1 is identical with main live-rollers 6, is clickwise, and auxiliary rotating shaft 2 is auxiliary is well wound up on main shaft 1 by film, hand of rotation is conter clockwise.
During utility model works, film is first through main live-rollers 6 with from live-rollers 7, after being flattened by main live-rollers 6, through auxiliary rotating shaft 2, be wound onto on main shaft 1 again, due in the auxiliary rotating shaft 2 away from main live-rollers 6, be socketed with a becket 3, described becket 3 upper surface is concordant with auxiliary rotating shaft 2, because becket 3 and auxiliary rotating shaft 2 are socketed, when auxiliary rotating shaft 2 is rotated, becket 3 does not rotate, becket 3 connects an electrostatic line 4, when after electrostatic line 4 ground connection, the electrostatic on the film that is in contact with it can be removed.Electrostatic line 4 is gone back connection metal clamp 5, can be clamped on grounded metal, very convenient.
Certainly, becket 3 can arrange two, lays respectively at the two ends of the auxiliary rotating shaft 2 at its place, and each connection one electrostatic line 4.Because main live-rollers 6 Surface coating has cashmere-planted layer, can increase the contact surface of it and film, add the semi-round arrangement mode of protruding 8, during with film contacts, can to extend film as both sides, flatten film, cashmere-planted layer is soft simultaneously, can not damage film.
