Abstract
The utility model discloses a vacuum-adsorption film drawing device of a vertical filling and packaging machine, which comprises a forming cylinder of a former. Synchronous belt film drawing devices are respectively arranged on two sides of the forming cylinder of the former, each synchronous belt film drawing device comprises a mounting base, a drive wheel and a driven wheel are rotationally mounted on the mounting base, a synchronous belt in circulating transmission is sleeved between the drive wheel and the driven wheel, a plurality of through holes are distributed on the synchronous belt, and one side surface of the synchronous belt is opposite to the outer surface of the forming cylinder of the former. Meanwhile, a negative pressure chamber connected with a vacuum pump is arranged on each mounting base, arranged on the inner side of the corresponding synchronous belt, and provided with adsorption ports corresponding to the through holes on the synchronous belt. Compared with a conventional film drawing mode relying on friction force, the vacuum-adsorption film drawing mode adopted in the vacuum-adsorption film drawing device has better effect, avoids offset and slipping during film drawing process, and accordingly increases film feeding accuracy.
Description
Technical field:
The utility model relates generally to vertical filling wrapping machine field, relates in particular to the vacuum suction film drawing device of vertical filling wrapping machine.
Background technology:
In the prior art, the film drawing device of wrapping machine bag former comprises the former forming tube, be with film drawing device synchronously for two of former forming tube both sides, the band film drawing device comprises two synchronous pulleys and the synchronous band that is stretched on two synchronous pulleys synchronously, the part outside face of band synchronously compresses mutually with the outside face of former forming tube, packaging film passes between synchronous band and the forming tube, produces force of sliding friction formula packaging film that static friction force produces greater than packaging film and forming tube and can follow synchronous band and move together between synchronous band and packaging film.Though this mode can reach the purpose of pulling packaging film, be the effect of friction force still owing to what rely on, be easy to generate between packaging film and the synchronous band and skid, generation is offset when causing film to move, and relies on the mode of friction force membrane also unreliable.
The utility model content:
The utility model purpose is exactly in order to remedy the defective of prior art, a kind of vacuum suction film drawing device of vertical filling wrapping machine to be provided, and it can prevent packaging film and the skidding between the band synchronously.
The utility model is achieved through the following technical solutions:
The vacuum suction film drawing device of vertical filling wrapping machine, it is characterized in that: include the former forming tube, former forming tube both sides are respectively arranged with synchronous band film drawing device, the band film drawing device includes mount pad synchronously, be rotatablely equipped with driving wheel and flower wheel on the mount pad, be set with the synchronous band of circulation transmission between driving wheel and the flower wheel, be with synchronously to be distributed with some through holes, relative with a side surface synchronously with the outside face of former forming tube; Each mount pad is provided with the negative pressure chamber that links to each other with vacuum pump, and each negative pressure chamber is positioned at the corresponding inboard of band synchronously, and negative pressure chamber is provided with and is with the cooresponding suction inlet of lead to the hole site synchronously.
The vacuum suction film drawing device of vertical filling wrapping machine is characterized in that: described being with synchronously is evenly distributed with some through holes.
The axial line of described driving wheel and flower wheel parallels, and vacuum chamber faces the former forming tube, and described being with synchronously has a plurality of holes, and described hole is connected with vacuum chamber.
Described vacuum chamber is provided with vacuum pump, and vacuum pump is connected with vacuum chamber by pipe.
The utility model is by being provided with vacuum chamber, and opening a plurality of holes with vacuum chamber being with synchronously of closely linking to each other, and packaging film being adsorbed on tightly is with synchronously, follows synchronous band and moves together, thereby reach the purpose of membrane.
The utility model has the advantages that:
The applied vacuum suction membrane of the utility model mode ratio is the mode better effects if of frictionally membrane in the past, in the membrane process, can not produce skew and skidding, thereby has improved the accuracy of film feeding.
Description of drawings:
Fig. 1 is a front view of the present utility model.
Fig. 2 is a left view of the present utility model.
The specific embodiment:
Referring to accompanying drawing.
The vacuum suction film drawing device of vertical filling wrapping machine, include former forming tube 1, former forming tube 1 both sides are respectively arranged with a left side band film drawing device 2 and the right film drawing device 3 of band synchronously synchronously, left and right synchronous band film drawing device 2,3 includes mount pad 7 respectively, be rotatablely equipped with driving wheel 4 and flower wheel 5 on the mount pad 7, what be set with the circulation transmission between driving wheel 4 and the flower wheel 5 is with 6 synchronously, be with synchronously and be evenly distributed with some through holes 9 on 6, relative with 6 one side surfaces synchronously with the outside face of former forming tube 1; Each mount pad 7 is provided with the negative pressure chamber 8 that links to each other with vacuum pump, and each negative pressure chamber 8 is positioned at corresponding synchronously with 6 inboard, and negative pressure chamber 8 is provided with and is with the cooresponding suction inlet 10 in through hole 9 positions on 6 synchronously.
