1. Introduction of automatic weighing and packing machine
Many companies start to use automatic packaging production lines for production in order to improve the competitiveness of their products in the market. For products, packaging is essential. The packaging machine, as the name suggests, is a machine that packs products. With the development of the fertilizer industry, the requirements for its packaging have become higher and higher, and some traditional packaging equipment can no longer meet its needs. So there are some high-precision packaging equipment, such as automatic weighing and packing machines.
2. How does the automatic weighing and packing machine work?
The automatic weighing and packing machine is mainly composed of a belt feeder, a self-unloading weighing hopper, a bag receiving hopper, and an electric control device, etc., with good performance. The belt feeder is composed of a layer gate, a conveyor belt, and a switch gate. The automatic weighing and packing machine uses a two-speed motor to control the conveying speed of the conveyor belt and the height of the material layer at the discharge port, so as to control the feeding amount to achieve the accurate target. The dump weighing bucket is mainly connected with the weighing sensor through joint bearings or cylindrical pins, so that the mass of the weighing bucket and the load can be accurately displayed on the weighing instrument. The discharge door at the bottom of the automatic weighing and packing machine is generally driven by a single cylinder, which can keep the weighing hopper relatively balanced during the entire working process.
As the main component of the automatic weighing and packing machine, the electronic control device not only has functions such as coarse metering, fine metering, overshoot compensation and discharge control, but also can carry out a higher conversion rate. When the load exceeds the allowable range, it will play the function of self-protection after power failure. When the automatic weighing packaging machine is weighing materials, the electronic control device controls the coarse and fine feeding of the feeder through the load change of the sensor. When the preset quality is reached, the feeder will stop feeding and send a discharge signal. The automatic weighing and packing machine is very simple in actual operation, and the packaging speed and accuracy can easily meet the requirements. It is an automatic packing machine that is very suitable for fertilizer packaging.
