The automatic sauce packaging machine is already a relatively familiar mechanical product in our life. Today, we Tea Horse Machinery will tell you about the working principle of the automatic packaging machine. How does it pack the chili sauce into the packaging bag quantitatively? Follow our after-sales technology to find out.

Structural performance and working principle:

1. The sauce liquid packaging machine is controlled by a single cylinder of the screw feeder, which brakes more quickly and has better sealing performance. When the stroke of the cylinder is small, the double doors open and start feeding into the metering hopper. When the metering value is reached, the compressed air is in the Under the control of the solenoid valve, the air cylinder is reversed and the air intake is turned, so that the cylinder pushes the double doors to engage and stop feeding, so as to achieve the purpose of weighing.

2. The bracket is the basis of the whole set of weighing equipment. It is mainly used to support the feeder and the metering mechanism. It is composed of a base, a pillar, a hat head, and a soft connection. The joint structure between the bottom plate and the column ensures the overall stability. Solid and balanced, the hat head and the column are connected by bolts, which are detachable and easy to install and maintain. The soft connection ensures a tighter connection between the feeder and the metering hopper without leakage or spillage.

3. The metering system is the core of the whole equipment. It is composed of the main part of the metering hopper, the cylinder, the sensor, the bag clamp switch, the solenoid valve and the air filter. When weighing, put the packaging bag under the metering hopper. Touch the bag clamping switch, at this time, under the action of compressed air, the piston of the cylinder moves forward, pushing the bag clamping device to clamp the packaging bag, and at the same time, under the action of compressed air, the feeder air drives the piston rod to shrink, and the double doors of the feeder are opened to start feeding When the measured value is reached, the sensor (strain gauge pressure sensor, using the strain gauge as a conversion element, converts the measured force into a change in resistance value, and then obtains a volt-level power output through a bridge circuit , the instrument equipped with the electronic control system will display the instantaneous weighing teaching value/signal synchronously in time. Through the electrical control system, the electromagnetic commutation will be controlled in time, and the air-operating rod will be pushed under the action of the compressed air to close the double doors of the feeder. , the clamp bag system is released to complete a weighing.

4. Electrical control system The electrical control system is the control center of the whole system. It is mainly composed of instrument display, thermal overload relay, air switch, AC contactor, button switch and power indicator light.
