Abstract
The utility model discloses a plastic film tension unreeling controller, comprising a transition roller group and a tension controlling mechanism; the tension controlling mechanism comprises an upper layer film controlling part and a lower layer film controlling part; a four-connection rod mechanism formed by a swing arm roller, a swing arm, a support arm and a crank throw is arranged in each of the upper layer film controlling part and the lower layer film controlling part; the two four-connection rod mechanisms are synchronously operated and controlled by a linkage rod with a screw structure; and in the upper film controlling part, a damping part formed by an offset adjusting roller and an offset adjusting plate is arranged in the motion direction opposite to the swing arm. The plastic film tension unreeling controller changes the orthogonal tension damping mode in the traditional technology, adopts the non-orthogonal swing arm-type damping method, and effectively overcome the problems of easy deflection of the film, severe film tension change, low integral operation speed and low efficiency.
Description
Technical field
The utility model relates to the plastic sheeting manufacture field, particularly a kind of plastic sheeting tension force unreeling control device.
Technical background
Add man-hour double-plastic is transmitted, usually need to transmit respectively upper and lower layer plastic sheeting.When plastic sheeting transmitted between each delivery roll, the speed of advancing the film roller there are differences with the speed of membrane roller, because the cause of thin flexible film can produce tension force.Usually can take regulate plastic sheeting tension force (referring to Figure of description 1) by the method for three tension roller vertical up and down movements, but film performance there are differences, so there is certain drawback in the method in the situation that do not affect film quality.
The conventional transmission mode adopts three tension roller that upper and lower layer film is transmitted mostly.At first, upper slice plastic sheeting and lower plastic sheeting respectively via the transition roller, again by three tension roller, are dragged forward by the traction rubber rollers at last.Three tension roller realize the adjustment of tension force under the traction of motor, its path of motion is for vertically.But the adjustment of adopting three tension roller to carry out plastic sheeting tension force has following shortcoming: 1) the easy left and right sideslip of film; 2) tension force reacts insensitive under fast state, and the tension force jumping phenomenon is serious; 3) overall operation speed is low; 4) easily heating, fault rate are high, affect service life.
The utility model content
For the drawback that above-mentioned conventional art exists, the utility model is intended to propose a kind of plastic sheeting tension force unreeling control device.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of plastic sheeting tension force unreeling control device, comprise transition cylinder group and tension control mechanism, described tension control mechanism comprises upper and lower layer film function unit, in these two parts, be provided with a four-link mechanism that is formed by swing arm cylinder, swing arm, strut bar and crank throw, between two four-link mechanisms by the gangbar synchronous manipulation of screw configuration;
In the topmost thin film function unit, with swing arm counter motion direction one damping components that is made of tuningout cylinder and tuningout plate is set;
In the lower film function unit, be provided with two patterns and adjust cylinder.
Two sides of described gangbar are provided with upper and lower adjusting nut.
Described transition cylinder group is the concentric cylinder of one group of same configuration, its be distributed in film input, tensioning, export each end position.
Described upper and lower layer film at output roller to drawing between rubber rollers, two laminated and outputs.
The utility model beneficial effect is: changed quadrature tension force damping mode in the conventional art, adopted non-orthogonal swing arm type damping method, actv. has overcome the easy sideslip of film in the orthodox method, and the memberane stress sudden change is serious, the problem of the slow inefficiency of overall operation speed.

Fig. 2 is the utility model structural representation;
Among its figure: the 1-topmost thin film; 2-transition cylinder; 3-top link cylinder; The 4-top link; 5-tuningout cylinder; 6-tuningout plate; 7-adjusted nut; The 8-gangbar; Setting nut under the 9-; The 10-pattern is adjusted cylinder; 11-lower swing arm cylinder; The 12-lower swing arm; The 13-lower film; 14-draws rubber rollers; 15-three tension roller (on); 16-three tension roller (descending); The 17-upper support bar; The 18-lower support bar; The upper crank throw of 19-; Crank throw under the 20-.
The specific embodiment
The below is elaborated with reference to the utility model preferred embodiment accompanying drawing 2.
The utility model is provided with up and down two by swing arm cylinder 3 and 11, swing arm 4 and 12, strut bar 17 and 18 and the four-link mechanism that forms of crank throw 19 and 20, between two four-link mechanisms by the gangbar synchronous manipulation of screw configuration, two layers of plastic thin films is up and down carried out tension adjustment, wherein and swing arm 4 and 12 centered by the junction, carry out within the specific limits circular arc and rotate.
Topmost thin film 1 and lower film 13, respectively via transition roller 2, by front and back reciprocally swinging swing arm cylinder 3 and 11, by upper and lower swing arm 4 and 12, the front and back reciprocally swinging is realized tension adjustment under the traction of motor.Upper and lower swing arm 4 and 12 is by gangbar 8 interlocks.Topmost thin film 1 is by tuningout cylinder 5, and tuningout plate 6 can move and carry out bias correction, drags the levels plastic sheeting by traction rubber rollers 14 at last and travels forward.This utility model device can, prevented because the film deformation situation that the tension force sudden change causes occurs, and realized the effect of complete machine high-speed operation.
The utility model is not limited only to two layers of plastic thin films is up and down carried out tension adjustment, can increase on this basis many plastic sheeting tension force unreeling control devices, simultaneously multilayer plastic film is carried out tension adjustment.
In order to guarantee that nip rolls batch the stability of plastic sheeting tension force, so that plastic sheeting tension force is maintained within a certain range, in the whole process of stretched plastic film, all keep constant tension force or taper tension, when starting the rouleau plastic sheeting, can not break because of overtension plastic sheeting; When starting large volume plastic sheeting, can not relax, and under the state that accelerates, slows down, stops, also not having film or the lax situation of film broken.
The above only is a preferred embodiment of the present utility model; can not limit protection domain of the present utility model with it; the utility model also can have other structural change; so long as the equalization of doing according to protection domain of the present utility model changes and modify, all should belong in the scope that the utility model contains.
