Introduction to BCJ-Z25B series semi-automatic Packaging Scale for granules:

This machine is equipped with a digital display weighing control instrument system and operates on a liquid crystal display screen. It has the advantages of stable performance, fast weighing speed and high precision. It is suitable for weighing, measuring and packaging granular materials such as rice, rice and corn. The operation interface is in Chinese/English, and the system has good stability and corrosion resistance. Programmable timer for process time control, with automatic drop correction, automatic zero tracking, overshoot detection and suppression function, and automatic alarm function. The operation interface is used to set the working parameters, which can be operated manually or automatically, and the two modes can be switched at any time to control the automatic operation among the units of the entire equipment.

1.304 stainless steel storage bin:

It is used to temporarily store the materials lifted by the hoist, with a general volume of 0.3 cubic meters, and the specific size can be customized as needed. The storage bin is directly mounted above the packaging scale and connected to the transitional storage bin of the packaging scale; There is a stop-screw level switch on the storage bin to monitor the level. When the material in the bin exceeds the upper stop-screw level switch, the hoist will automatically stop lifting.

2. Metering mechanism

This series of electronic scale feeding system uses program automation control for coarse and fine feeding; The coarse feeding controls the packaging speed, the small feeding controls the packaging accuracy, and when the coarse feeding reaches 95%, the small feeding fills 5%. Therefore, this feeding method ensures both the packaging speed and the packaging accuracy.

3. Bag-clamping mechanism

With an outwardly open bag clamping mechanism, it is convenient and secure for bag clamping; Easy to operate and maintain; It is equipped with dust removal pipes to prevent dust backflow.

4. Weighing scale feeding mechanism:

The feeding mechanism supplies materials directly to the weighing hopper through coarse and fine feeding, effectively completing the measurement and packaging of materials. Fine design, small drop, high sealing, static weighing bucket, bucket body fixed to UB2/100kg sensor (sensor performance: Model: UB2/100kg type; Output sensitivity: 2mv/v Accuracy class :0.02 Repeatability :0.02%; Temperature compensation range :-10 ° C to 60 ° C; Operating temperature range -30 ° C to +65 ° C; Allow overload :150%), to make it have no direct contact with the outside for higher precision, cone transition hopper, no hygiene dead corners, complete discharge.

Workflow

a. Turn on the power switch and see if the power indicator light is on. If it is not on, check if the power is connected properly.

b. Manually point the parts to see if they work properly;

c. Set the recipe (the recipe can be done according to the user manual)

d Turn on Auto

e. Automatic material lifting - automatic metering, material filling - finished product conveying - vacuuming and sealing

f. The entire packaging process is completed.

What’s the difference between vacuum and non-vacuum packaging speeds?

Vacuum packaging requires additional sealing and air extraction steps, reducing speed to 3-4 packs/min. Non-vacuum mode skips this for general packaging, reaching 6-10 packs/min.

How often does the machine need maintenance?

Routine maintenance (cleaning sensors and hoppers) is recommended every 2 weeks. The weighing sensor and solenoid valve have a service life of 2-3 years under normal use.

Is the machine explosion-proof?

Yes, it’s designed with explosion-proof considerations for dust-prone environments, complying with industrial safety standards for granular material processing.

Can it handle granular materials with irregular shapes?

Yes, as long as the material is free-flowing (particle size 0.5mm-10mm). Irregular shapes won’t affect the weighing accuracy or feeding system.

Material contact parts upgrade: Optional food-grade 316 stainless steel for pharmaceutical or high-purity material packaging.

Hoist coordination: Customized storage bin height to match existing hoist systems in the production line.

Training support: On-site operator training and video tutorials tailored to specific production processes.

Spare parts package: Customized spare parts kits based on expected usage frequency (e.g., high-wear components like sensors).
