Definitions

  • the present invention relates to an auto strapping packaging tool, and more particularly, to an auto strapping packaging tool used when packaging goods and the like using a plastic band.
  • Auto strapping packaging tools have portable tool types and are used to package goods such as boxes using plastic bands.
  • Packaging is performed by wrapping goods using a plastic band to form a loop and tightening the plastic band using an auto packaging tool until a predetermined magnitude of tension is generated on the loop.
  • a subsequent process is performed by bonding portions of the plastic band which overlaps itself in two layers.
  • the bonding is mainly performed by using friction heat generated by vibrating the plastic band in a state in which the plastic band is pressed. Accordingly, solid bonding between homogeneous materials is performed on the plastic band in a locally molten state. Then, when the bonded portions are cooled, a solid loop is formed.
  • one cylindrical brushless direct current (BLDC) motor is disposed and controlled in the conventional strapping packaging tool. Accordingly, since an internal structure becomes complex and high vibration is transmitted to other apparatuses in a welding process, there is a problem of badly affecting the durability of internal components. In addition, since a layout of the components is limited due to the long cylindrical BLDC motor, an unbalance occurs in the overall weight distribution, and thus inconvenience is raised in terms of usability.
  • BLDC direct current

  • first power generated by the first motor 210 may be transmitted to the feed wheel part 220 through the first driving shaft, the first shaft a1, and the worm gear unit.
  • the tension module 200 may further include an annular ring portion 240 which is coupled to the feed wheel part 220 and is rotated about the first shaft a1, and on which a first tooth 241 is formed on one part thereof, and a protruding piece 242 is formed on another part thereof in a radial direction.
