  • Patent number: 6070399
    Abstract: The present practical new design is to provide a guide feeding device for thermal-shrinking film mechanism that mainly is related to the feed wheels which are mounted on the upper, middle and lower peripherals of the central guide rod and all connected by the connecting rod. The transmission gears are driven by a motor to let another meshed transmission gear adverse transmitted correspondingly and to stably transport the shrinking film downwards. By the opposed reverse threads at both ends of an axial rod, each feed wheel is mounted on the corresponding reverse thread and an adjusting wheel is mounted on the other end of the axial rod. And it only needs to rotate the adjusting wheel and move the two mutual opposed feed wheels along the axial rod in or out correspondingly to adapt the central guide rods with different sizes. The adjustment is very convenient and fast, and is able to upgrade the producing efficiency and the product quality.

  • Patent number: 5992492
    Abstract: A horizontal type thermo-shrinking film labeling machine includes a tubular thermo-shrinking film dispensing wheel controlled to let off a thermo-shrinking film, a film delivery uni controlled to deliver the thermo-shrinking film forwards, a central guide shaft which guides the thermo-shrinking film in an opened status, a cutter unit controlled to cut the thermo-shrinking film being delivered from the central guide shaft, a packing wheel rotated to pick up the cut pieces of the thermo-shrinking film, permitting the cut pieces of the thermo-shrinking film to be sleeved onto products carried thereon individually, a feed unit controlled to feed products to respective receiving troughs on the packing wheel, a conveyer controlled to carry thermo-shrinking film packed products to a heating unit for heating, enabling each cut piece of the thermo-shrinking film to shrink and to be firmly secured to the periphery of the corresponding piece of product.

  • Patent number: 5916343
    Abstract: A thermo-shrinking film cutting mechanism used in a labeling machine, including a plurality of cutter units mounted on locating frames and equiangularly spaced around a center guide shaft, each cutter unit including a crank shaft, axle bearings, a coupling plate, an index plate, a locating plate, a cutter holder, a cutter blade and a clamping plate, a transmission mechanism driven to rotate said cutter units, causing said cutter units to cut a thermo-shrinking film, the transmission mechanism including a transmission disk having a plurality of receiving holes, which hold a respective axle bearing, which supports the eccentric upper section of one crank shaft, enabling the crank shafts of the cutter units to be rotated synchronously when the crank shaft of one cutter unit is rotated by a transmission belt through a transmission wheel, the cutter holder being slidably mounted in a transverse bottom groove on the locating plate and fixed in place by an adjustment screw to hold the respective cutter blade at the
