• 4. Main structure and function.

  The whole machine is composed by the conveyor, packing machine, shrink machine, no-power rear conveyor motor and electrical control, pneumatic control, etc.

  4.1 Packing machine. The packing machine is composed by rack, bottle-dividing body, bottle-pushing body, film-putting body, wrapping body, etc.

  4.1.1 The bottle-sending body in charge of sending the PET bottles to the bottle-dividing body, and divide into two parts: fore-conveyor and back-conveyor.

  4.1.2 The bottle-dividing body in charge of the PET bottles parsing according to the packing requirement to carry out the promote wrapping film.

  4.1.3 The bottle-pushing body in charge of pushing forward the PET bottles and making the film wrapping.

  4.1.4 The film-putting body in charge of supplying the PET bottles film wrapping.

  4.1.5 Wrapping: According to the packing size, set the packing film size according to detection system, automatic finish wrapped film synchronism during the product moving forward.

  4.2 Shrink machine The shrink machine is composed by the three parts: heat shrink, cooling and forming, product conveyor.

  4.2.1 Heat shrink machine It is in charge of heating and shrinking the wrappage, to make the film shrink even under the setting temperature, and cling to the wrappage surface, which to carry out the packing purpose.

  4.2.2 Cooling and forming It is in charge of cooling the film on the wrappage surface swiftly, which make the film to high strength, and let it easy to handle.

  4.2.3 Product conveyor Transport the wrappage to the no-power conveyor; the no-power conveyor belt has the temporary storage function, and it is convenient for staff to palletize or handle.
