Sachet Machine For Sugar

This sachet machine for sugar integrates a multi-lane metering structure with a four-side-seal packaging process, executing material distribution, film transport, bag forming, granule filling, heat sealing, and final cutting-all within a single, continuous production workflow. Each packaging channel operates according to a set rhythm, effectively eliminating the repetitive manual tasks-such as weighing, feeding, and sealing-typically associated with conventional manual packaging processes.

In practical production, the equipment's metering configuration can be tailored to the specific characteristics of the material-including granule size, shape, bulk density, and flow properties-to meet the unique packaging requirements of various products. A film-pulling and positioning mechanism precisely controls the movement of the packaging material, while a heat-sealing assembly seals all four sides to create individual, self-contained sachets. The system is highly flexible, allowing for adjustments to sachet dimensions, metering ranges, the number of packaging lanes, and auxiliary feeding configurations to suit specific client production needs.

Once the equipment is started, the packaging film is fed from the unwinding stand into a slitting unit. Here, circular blades divide the wide film web into multiple individual strips, which are then guided by rollers to ensure smooth, stable transport for each strip.

Next, a servo-driven film-pulling system advances the film according to the pre-set bag length. Each lane is controlled independently, with automatic adjustments to the film position to minimize length deviations. Granular products move from the hopper into a metering unit; once the precise quantity is measured, the material is dispensed into the bag through a filling nozzle, followed by longitudinal and transverse sealing.

The transverse sealing unit seals the bag opening through heating and compression. During this stage, the system also applies date codes and creates easy-tear notches. Finally, a cutting blade separates the individual packaging bags, discharging the finished products.

The feed inlet should be designed with consideration for the actual feeding method, hopper capacity, and material flow characteristics. A well-designed feed structure helps minimize the accumulation of particles at the inlet while facilitating replenishment and routine cleaning.

Adjustments can be made based on the configuration of the metering system to accommodate different package weights. When switching materials, it is necessary to re-verify the actual fill weight; in particular, because bulk densities vary among different granular products, the existing metering parameters cannot simply be reused.

The sachet machine for sugar cutter drive mechanism controls the cutter to perform the cutting operation. It must remain synchronized with the movement of the packaging film and the sealing cycle to prevent deviations in bag length or inaccuracies in the cutting position.

Temperature controllers are used to set and monitor the operating temperatures of the respective heat-sealing zones. Operators can adjust temperature parameters based on the heat-sealing characteristics of the packaging film material.
