Automatic stretch hooder

Variety of pallet sizes that can be packaged.

The film stretching mechanism has a built-in position sensor that provides smooth adjustment of the stretching degree.

The automatic contour detection system allows you to determine the dimensions of the items stacked on the pallet and adjust the size of the packing bags accordingly.

The equipment has a high adaptability and performance.

A user-friendly user interface has been developed for easy setup and use of the system, as well as an intelligent diagnostics and support system to speed up operation and simplify maintenance.

    Product Description

    Traditional way

    The traditional way of packaging goods on pallets is to wrap the packaging film, that is, to wrap the polyethylene film layer by layer through a semi-automatic or automatic wrapping machine. This is not only time consuming, but often creates a lot of waste. There are many layers of film and the quality of the packaging is not good enough to protect the goods during transportation, resulting in unnecessary expenditure on packaging materials. If it needs to be dust-proof and moisture-proof, it must be covered with a film. When the buyer inspects the goods, he needs to tear off the stretch film and re-wrap the film, which is a laborious and time-consuming process.


    Advanced way

    The new high-speed pallet packing method is cold stretch hood, which not only meets the requirements of environmental protection and energy saving, but also provides a convenient way to protect goods. Cold stretch film completely covers the products and the pallet from top to bottom, tightly wrapping, acts as a water and dust protection. Film shrinkage ratio (LLDPE): 17-20%, the thickness is only 0.1mm, and the amount of material per pallet is only about 500-560g, which can greatly reduce the cost of packaging materials.

    Productivity is high when wrapping with stretch film, and different sized films can be used to wrap different sized pallets. The high elasticity of the film prevents damage to the goods during transport and storage. Hermetically sealed packaging protects against external influences.

    Working Principle

    The open top bag filling machine consists of a control system, a feeder, a weighing sensor, a clamping device for bags, a selaing mechanism, a belt conveyor, a frame, and a pneumatic control system. The feeding system uses two-speed feeding, fast feeding ensures output, and slow feeding frequency conversion control ensures accuracy; bag clamp weighing system consists of weighing brackets, sensors and bag clamp arms; the frame supports the entire system, providing stability; The control system controls the feed valve and the bag clamp. The packing shape of the product adopts the clamping of the bag in place, and at the same time, there is enough material in the storage bin, the valve automatically opens, the material is discharged into the bag, and weighing is carried out at the same time. When the first target weight is reached, slow feed continues until the second target weight is reached, stop filling, display the final weighing and automatically lose the bag.
