The speed of the screw operation measured by the weighing and discharging machine is converted into the corresponding pulse signal. After photoelectric isolation, it is sent to the computer. The computer communicates with the PLC to detect the flow rate and the operating status of the feeding motor. After the computer calculates the instantaneous flow rate and compares it with the required flow rate, it outputs the corresponding speed regulation signal. After photoelectric isolation, the DA is converted into a 4-20mA speed regulation signal to adjust the operating frequency of the frequency converter, thereby controlling the operating speed of the feeding motor and achieving the purpose of controlling the feeding amount for batching.
020-34563445The weighing and discharging machine mainly consists of a frame with a discharging hopper, an electric hoist, a diaphragm valve, a pneumatic massage device, a dust removal device, etc. The ton bags are transported from the ground to the feeding port of the equipment by cranes or forklifts. Then, the diaphragm valve is opened manually, and the ton bag opening is dropped into the inlet of the silo. After that, the diaphragm valve is closed, and the discharge port of the ton bag is opened at the quick-opening bag opening on the side, thus achieving the effect of discharging.
The batching equipment mainly uses pneumatic massage plates and vibration devices to promote the materials in the ton bags, thus enabling good discharge. The frame support structure of the unloading station, the mud bag elevator, the mud bag hanger, the mud bag support massage plate, the bag opening control valve, and the sealing device. It can be designed in combination with the glove box to achieve 100% isolation of dust and gas from the operator. A fluidizer can be selected, and a blockage breaker can be installed under the hopper. The weighing funnel can also serve as a thief. Rotary valves and gravity Feeders, screw conveyors, vibrating conveyors, tubular chain conveyors, rotary valves and air flow, vacuum conveying, etc. A cargo crane: A self-propelled cargo crane that lifts bags (ton gunny bags) onto the frame of the unloading platform without external assistance.
Product features
The overall functions of the ton bag feeding station for powder pneumatic conveying equipment are relatively complete, and it can well handle the feeding of raw materials for small bag packaging and the powder feeding for ton bag packaging.
2. Whether it is the small bag powder without complaint or the ton bag powder, it is relatively easy to unpack and convenient to maintain in the later stage.
3. To ensure smooth and comfortable discharging and minimize residue, pneumatic massage devices are equipped for opening bulk bags, and vibrators are provided for opening small bags.
4. The ton bag feeding station of the powder pneumatic conveying equipment is equipped with corresponding dust removal equipment. During the feeding process, there is no dust flying, which will not affect the production environment.
5. Flexible selection and configuration: Dust removal equipment, vibrating hoppers, air hammers, rotary valves, screening machines and other related equipment can be selected according to different needs.
6. The interior of the equipment is designed with no dead corners, making it easy to clean and disassemble.
7. The overall design of the machine fully complies with GMP standards.
