3、 Structure and principle
1. Working principle: The mechanical part is controlled by the electrical part to drive the discharge conveyor device, which quantitatively fills the material into the packaging bag. The two nozzles can be used to fill the bag at the same time, and except for manual bags, continuous filling, metering, bag dropping and other operations are automatically completed.
2. Structure: The packaging machine consists of the following main parts:
① Upper storage device ② Material conveying part ③ Weight control mechanism ④ Bag clamping device ⑤ Weighing mechanism
⑥ Automated computer control system ⑦ lower dust collection pipe ⑧ upper dust collection port
3. Main structural functions:
⑴ Upper storage device: welded with iron plates and pipes, it plays a temporary and small storage role for coal balls. It should be noted that the amount of material inside should always be no less than two-thirds, otherwise it will affect the efficiency and accuracy of bagging.
⑵ Material conveying section: The chain plate conveyor is driven by a 0.75 kW RV motor reducer to complete material canning. The direction and speed of rotation are set at the factory.
⑶ Weight control mechanism: Controlled by a cylinder between the conveying section and the bag clamp, when the material enters the bag and the weight is about to reach the bag weight (which can be set), the cylinder automatically blocks the material conveying volume, controls the feeding volume and speed, and achieves accurate and quantitative supply of materials.
⑷ Bag clamping device: composed of a bag clamping cylinder and a bag clamping switch, fixed at the bag clamping discharge port. After the worker puts on the bag, the bag clamping switch is triggered, and the bag clamping cylinder automatically works to clamp the bag.
(5) Weighing mechanism: The weighing mechanism consists of a unit weighing mechanism composed of a microcomputer scale, instruments, sensors, bagging rack, and spring support. The weighing range is 25kg-50kg. When the weight reaches the set value, the microcomputer scale outputs a signal, and the cylinder acts as an actuator to close the gate and achieve automatic measurement.
(6) Automated computer control system: The automation control of the packaging machine is completed by it, located in the distribution box, and attention should be paid to moisture-proof and dust-proof treatment.
(7) Lower dust collection port: used to collect powder materials brought back by the upper canning conveyor. Before using the packaging machine, tie the bag on top and recycle the materials.
⑻ Upper dust collection port: It should be connected to the dust removal fan in the user's factory to collect dust generated during material bagging and purify the working environment of workers.
For the electrical part, please refer to the electrical user manual and electrical schematic diagram.
