Abstract
The utility model discloses a film tube diameter adjusting mechanism of a film blowing machine. The adjusting mechanism comprises a plurality of lines of rolling rods which are arranged around the circumference of a film tube channel, each line of rolling rods corresponds to a vertical support plate, and the upper and lower ends of the vertical support plate are fixed on a polygonal frame. The film tube diameter adjusting mechanism is characterized in that each rolling rod is arranged on a rolling rod support, the rolling rod supports are connected onto vertical support plates through expansion links and are further connected with adjusting screw rods; the adjusting screw rods are screwed in the inner holes of worm gears in a threaded way, the worm gears are rotationally arranged on the vertical support plates, worms matched up with the worm gears are arranged on vertical revolving shafts, and the vertical revolving shafts are rotationally arranged adjacent to the vertical support plates; one vertical support plate corresponds to one vertical revolving shaft, the shaft end of each vertical revolving shaft is provided with a chain wheel, all chains wheels arranged on the shaft ends of the vertical revolving shafts are connected by the same chain in a driving way, and the chain is driven to drive by a motor. According to the film tube diameter adjusting mechanism, the radial distances of the rolling rods can be automatically adjusted, so as to quickly meet the production requirements of the diameters of different film tubes.
Description
Technical field
The utility model relates to a kind of inflation film manufacturing machine, is specifically related to a kind of film pipe diameter adjusting mechanism of inflation film manufacturing machine.
background technology
First inflation film manufacturing machine will extrude blown film shape film forming pipe by die head in the time producing plastic sheeting, the size of film pipe diameter directly affects the specification of produced film, the film pipe diameter adjustment of prior art is all to realize by the radial distance of manual adjustment roller, regulate trouble, workload is large, more can not in blown film process, finely tune, can not meet fast the need of production of different film pipe diameters.
Summary of the invention
In view of the problem that current known technology exists, the technical problems to be solved in the utility model is to be to provide a kind of radial distance that can automatically regulate roller, to meet fast the inflation film manufacturing machine film pipe diameter adjusting mechanism of different film pipe diameter need of productions.
For solving the problems of the technologies described above, the utility model takes following technical scheme to complete:
Inflation film manufacturing machine film pipe diameter adjusting mechanism, comprise the multiple row roller of laying around film tube passage circumference, the corresponding vertical support plate of every row roller, the upper and lower side of vertical support plate is fixed on polygonal frame, it is characterized in that: every roller is arranged on a roller bearing, roller bearing is connected on vertical support plate by expansion link, roller bearing is also connected with adjusting screw(rod), adjusting screw(rod) screw thread is screwed in the endoporus of worm gear, worm gear rotates and is located on vertical support plate, the worm screw mating with worm gear is installed in vertical rotating shaft, vertical rotating shaft is rotated and is arranged on the side of vertical support plate, , a corresponding vertical rotating shaft of vertical support plate, the axle head of every vertical rotating shaft is all provided with sprocket wheel, all sprocket wheels of installing at vertical rotating shaft axle head connect by same chain drive, the transmission of chain is by driven by motor.
Adopt after technique scheme, inflation film manufacturing machine film pipe diameter adjusting mechanism can regulate the radial distance of roller automatically, to meet fast the need of production of different film pipe diameters, its operation principle is: when driven by motor chain drive, will drive all sprocket wheels simultaneously, vertical rotating shaft and worm screw are rotated, the rotation of worm screw drives the rotation of worm gear, because being limited to roller bearing, adjusting screw(rod) can not rotate, so worm gear will drive adjusting screw(rod) moving linearly after rotating, under the flexible and rest effect of expansion link, adjusting screw(rod) drives roller bearing and roller to carry out radial action, thereby reach the radial distance of automatic adjusting roller, to meet fast the need of production of different film pipe diameters.
As preferably, described expansion link is made up of symmetrical each three lever arms, has two long lever arm and a quarter butt arm in three lever arms, and one end of two long lever arm is articulated and connected by quarter butt arm, and the other end is articulated and connected with vertical support plate and roller bearing respectively.Above-mentioned Telescopic rod structure has advantages of that distance of stretch out and draw back is long, can meet the adjusting on a large scale of film pipe diameter.
Accompanying drawing explanation
The utility model has following accompanying drawing:
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Accompanying drawing has represented the technical solution of the utility model and embodiment, further describes by reference to the accompanying drawings more each details and the operation principle thereof of embodiment below.
As shown in the figure, inflation film manufacturing machine film pipe diameter adjusting mechanism of the present utility model, comprise that the eight row roller 10(mono-that lay around film pipe 12 passage circumference are listed as the roller substantially comprising more than three), the corresponding vertical support plate 6 of every row roller 10, the upper and lower side of vertical support plate 6 is fixed on octagon framework 9, every roller 10 is arranged on a roller bearing 11, roller bearing 11 is connected on vertical support plate 6 by expansion link, roller bearing 11 is also connected with adjusting screw(rod) 4, adjusting screw(rod) 4 screw threads are screwed in the endoporus of worm gear 5, worm gear 5 rotates and is located on vertical support plate 6, the worm screw 2 mating with worm gear 5 is installed in vertical rotating shaft 3, vertical rotating shaft 3 is rotated and is arranged on the side of vertical support plate 6, , a corresponding vertical rotating shaft 3 of vertical support plate 6, the axle head of every vertical rotating shaft 3 is all provided with sprocket wheel 1, article eight, eight sprocket wheels 1 that vertical rotating shaft 3 axle heads are installed connect by same chain drive, the transmission of chain is by driven by motor, described expansion link is made up of symmetrical each three lever arms, has one end of two long lever arm 7 and 8, two long lever arm 7 of a quarter butt arm to be articulated and connected by quarter butt arm 8 in three lever arms, and the other end is articulated and connected with vertical support plate 6 and roller bearing 11 respectively.
The course of work of the present utility model is: when driven by motor chain drive, will drive all sprocket wheels, vertical rotating shaft and worm screw to rotate simultaneously, the rotation of worm screw drives the rotation of worm gear, because being limited to roller bearing, adjusting screw(rod) can not rotate, so worm gear will drive adjusting screw(rod) moving linearly after rotating, under the flexible and rest effect of expansion link, adjusting screw(rod) drives roller bearing and roller to carry out radial action, thereby reach the radial distance of automatic adjusting roller, to meet fast the need of production of different film pipe diameters.
