Abstract
The utility model discloses a thin film tensioning device of a packaging machine. The film tensioning device comprises a support, as well as an oscillating arm, a fixed shaft, a strengthening shaft and two thin film rollers, which are fixed on the support, wherein the upper end of the oscillating arm is rotatably connected through the fixed shaft, a cylinder is mounted on one side of the upper end of the oscillating arm, two ends of the cylinder are hinged on the support and the oscillating arm, an air expansion shaft is arranged below the support, and the air expansion shaft is fixed on the support.
Description
Technical field
The utility model relates to a kind of film tightening device of wrapping machine.
Technical background
By the final former that arrives behind a plurality of cylinders of packaging film process that twine on the inflatable axle, follow-up algorithm is carried out in moulding later in the wrapping machine film placing mechanism.If can not guarantee a slack-free step before packaging film enters the former mouth, packaging film is not just having under the slack-free situation by moulding so, sealing action and will make the packaging bag after sealing that the fold phenomenon is arranged afterwards; In addition, if packaging film was a plurality of cylinders of process before entering former, be to have bigger friction force so between packaging film and cylinder, if simple in this case comes membrane by slack-free driving band in the filming-drawing mechanism to the friction force that packaging film produces, not very reliable, have the phenomenon of skidding and produce.The stretching device of film just can strain at film flatly at the moulding toe-out under these circumstances, has also assisted the process of membrane simultaneously.
The utility model content
The utility model provides a kind of packaging film that can effectively solve just not having under the slack-free situation by moulding, sealing action and will make packaging bag after sealing that the film tightening device of fold phenomenon is arranged afterwards.
The utility model technical solution problem provides following scheme:
A kind of film tightening device of wrapping machine, comprise support, be fixed on swing arm, anchor shaft, reinforcement axle and two film cylinders on the support, it is characterized in that: be rotationally connected by anchor shaft in described swing arm upper end, side in described swing arm upper end is installed cylinder, described cylinder two ends hinge is the inflatable axle below support in support and swing arm, and described inflatable axle is fixed on the support.
The utility model is controlled by cylinder, the flexible stretching device that makes of cylinder is done the swing of certain angle around anchor shaft, the swing process to film be one by being relaxed to slack-free process relatively, when stretching device is put maximum angle in design process, packaging film by stretching device just in time is tightened up, and reaches desirable processing request.
Description of drawings
Fig. 1 is a structural representation of the present utility model
The specific embodiment
Referring to accompanying drawing, a kind of film tightening device of wrapping machine, comprise support 1, be fixed on swing arm 2, anchor shaft 3,4 and two film cylinders 5 of reinforcement axle on the support 1, swing arm 2 upper ends are rotationally connected by anchor shaft 3, in a side of swing arm 2 upper ends cylinder 6 are installed, and cylinder 6 two ends hinges are in support 1 and swing arm 2, be inflatable axle 7 below support 1, inflatable axle 7 is fixed on the support 1.
When work, after cylinder 6 actions, the swing arm 2 of the left and right sides is along the circumferential direction rotated together with anchor shaft 3, drives 4 and two cylinders 5 of reinforcement axle simultaneously and turns over certain angle around axle together.Do at cylinder 5 that packaging film is stretched in the process of swing, make its film surface tension smooth.
