Automatic shrink wrapping machine SH77

for heat-shrink films

The SH77 shrink wrapping machine is a combined machine that uses a single work station to perform the hooding and heat-shrinking operations of the product to be packaged. The SH77 type automatic hooding machine uses a coil of heat-shrinkable tubular film with side bellows. In the different versions, up to three film reels can be reached. The film is heat-shrunk on the product by means of a gas-powered ring oven; all functions are controlled by a PLC that manages the automatic and manual operations. The machine combines and synchronizes three distinct and independent phases in a single cycle - tubular bag preparation, hooding and shrinking - and articulates them in a single synchronized cycle that minimizes the downtime of the various devices and guarantees high levels of productivity. These cycle phases are normally performed during the phase of entering the new product to be packaged in the machine or parallel to the common cycle phases, therefore they do not affect the machine cycle time. An inflation system, installed on the clamps, facilitates the hooding of the film on the pack. The shrinking arch is separated from the hooding unit, this to allow an optimal shrinking of the film on the product thanks to the possibility of keeping the hood in the correct position at the base of the pallet and for the right time necessary to allow a perfect attachment of the film on the pallet thanks also to the overturning of the clamps towards the inside, to allow a shrinking of the film at the base of the product.
