The feed mechanism of film band material
Technical field
The present invention relates to a kind of feed mechanism of band-like film material.
Background technology
Printing or the conveying of packing with cut in the process, the band-like film material is in feeding and sub-material process, and it is inhomogeneous feeding to occur through regular meeting, and defectives such as skew take place the band material in feeding or the sub-material process, occur waste material easily, not only cause waste also can cause faults such as shutdown; If adopt the mode of manual correction, be easy to occur the industrial accident that hand is squeezed.
For example when PE tube material or the charging of PET film,, cause wastage of material because above-mentioned deficiency takes place the defective of existing feeding Mechanism Design easily.In the prior art, finish above-mentioned feeding operation by the feed mechanism of driving wheel drive flower wheel usually.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of feed mechanism that helps the smooth and easy feeding of retainer belt material, and it can reduce the probability that skew and fold take place for raw material in the feeding process, raising feeding efficient.
Its technical matters to be solved can be implemented by the following technical programs.
A kind of feed mechanism of film band material, comprise motor-driven drive roll and the loose metal roller that drives through drive roll, described drive roll is a friction roller, also be provided with idler roller between described friction roller and loose metal roller, along the sequencing of band material feeding, described friction roller both sides are respectively equipped with a pair of charging guiding roller and a pair of discharging guiding roller.
As the further improvement of the technical program, described idler roller comprises tensile force last idler roller and tensile force following idler roller down up.
Also as the further improvement of the technical program, an axial side of described friction roller, feeding roller, idler roller and charging guiding roller and discharging guiding roller is provided with a postive stop baffle.
As the further improvement of the technical program, each rotating shaft of described friction roller, feeding roller, idler roller and charging guiding roller and discharging guiding roller is installed on the described postive stop baffle.
Also as the further improvement of the technical program, described friction roller both sides recline mutually with described charging guiding roller and discharging guiding roller respectively.
Adopt the film strip feed mechanism of technique scheme, by friction roller and guiding roller that is mated and idler roller, give better controlled to the feedstock direction of film band material and band material tension force size, thereby avoided the skew of band material in the fill process, defective such as wrinkling.

The specific embodiment
The feed mechanism of film band material as depicted in figs. 1 and 2, feeding roller 7 is used for installing the material volume, strip is drawn from feeding roller 7, one group of tightening device tensile force control up and down through last idler roller 61 and 62 formation of following idler roller, make strip in the feeding process, can adjust the tensioning degree of charging strip easily, again through charging guiding roller 2, friction roller 3 and discharging guiding roller 1 are delivered to corresponding working procedures or machine with strip, wherein 2 one groups of charging guiding rollers totally two compress strip up and down, same discharging guiding roller 1 also be one group the both sides up and down of totally two office strips strip is compressed; For the power that the friction roller 3 that better transmits motor 5 drives provides, charging guiding roller 2 and discharging guiding roller 1 can be adjacent to friction roller 3.
Wherein, each rotating shaft of each running roller above-mentioned all has been fixed on above the adapter plate 8, and adapter plate 8 is in a side position of each running roller, has in fact formed a postive stop baffle, and strip 4 can carry out the adjustment or the setting of feeding with this adapter plate as the plane of reference of contraposition.
This mechanism is as the feed mechanism of band-like film material, can be during actual the use by coiled strip being placed on above the feeding roller 7, stub bar is walked around 5 tension wheels successively, again by charging guiding roller 2/ track adjusting wheel, draw through discharging guiding roller 1 again after walking around friction roller 3/ friction wheel then, motor 5 is propulsions source of this mechanism, and it drives friction roller travels forward strip 4.
