Stretch head for facilitating wrapping palletized loads

A stretch head for facilitating the wrapping of palletized loads within packaging or wrapping film comprises a vertical downright, and a carriage assembly vertically movable along the vertical downright. A base plate is mounted upon the carriage assembly and is inclined with respect to a horizontal plane so as to have a first end thereof disposed at a higher elevation than a second opposite end thereof. A supply roll of wrapping or packaging film is rotatably mounted upon the first higher end of the base plate, and a pair of tension rollers are mounted upon a substantially central portion of the base plate. A strain gauge roller is also mounted upon the base plate for receiving the wrapping film exiting from the tension rollers, a first idler roller is mounted upon the base plate for receiving the wrapping film from the strain gauge roller, and a second idler roller is mounted upon the second opposite end of the base plate for receiving the wrapping film from the first idler roller. Since the second idler roller is mounted upon the lowest end portion of the base plate, in view of the inclined disposition thereof, the second idler roller is capable of positioning the wrapping film at the lowest elevation whereby the wrapping film can be wrapped around the lowermost regions of the palletized load. The second idler roller also comprises a rubberized sleeve member for preventing movement of the wrapping film in an axial direction along the external periphery of the second idler roller so as to ensure proper positioning and orientation of the wrapping film with respect to the palletized load.

Universal tensile covering film packaging machine

The invention discloses a universal tensile covering film packaging machine which is used for wrapping a pre-tensioned cylindrical thin film on goods. The packaging machine comprises a film coil bracket (1), a lifting mechanism (2), a tensioning mechanism (3), a film feeding mechanism (4), a thin film heat-sealing and cutting mechanism (5), a main frame (6), a transmission mechanism (7) and the like, wherein the main frame (6) has a frame-shaped structure with four pieces of upright posts; the film coil bracket (1) is positioned on the outer side of the main frame (6); the film feeding mechanism (4) is positioned on the top of the main frame (6); the thin film heat-sealing and cutting mechanism (5) is positioned below the film feeding mechanism (4); the transmission mechanism (7) is positioned on the ground on the inner side of the main frame (6); the tensioning mechanism (3) is driven by the lifting mechanism (2) to perform rising and falling motions; left and right movable beams of the tensioning mechanism (3) are provided with upper and lower sliding racks; and the sliding racks are provided with film collecting and releasing mechanism and a film sucking mechanism. Because the film collecting and releasing mechanism and the film sucking mechanism are positioned on the same sliding rack, the tensioning mechanism (3) can automatically adapt to the cylindrical thin films of different widths by only adjusting the relative distance between the upper and lower sliding racks.
