technical field

The invention belongs to the technical field of packaging machines, in particular to a bag-feeding type online real-time metering automatic packaging machine.

the

Background technique

Inaccurate measurement has always been a problem in the packaging machine industry. The main reason is that the materials to be packaged have different characteristics. For example, materials with high viscosity are easy to stick to the blanking position, and materials with strong fluidity are too fast to control. It is easy to cause inaccurate measurement. Existing packaging machines usually use the form of one-time measurement and then packaging. The measurement is not accurate enough, and even has a large error. The products produced in this way are very unfair to consumers and will also damage the reputation of the manufacturer.

The bag feeding type online real-time metering automatic packaging machine provided by the present invention includes a bag loading device, a bag clamping device, a bag opening fork device, a bag opening blowing device, a blanking device, a sealing device, a rotating large plate, and a working table. A real-time metering device, a primary blanking screw and a secondary blanking screw, the real-time metering device is arranged between the blanking device and the sealing device, and the primary blanking screw and the secondary blanking screw are arranged above the real-time metering device; The real-time metering device includes an adjustment mechanism, a weighing sensor and a bag clamping mechanism, the bottom end of the adjustment mechanism is fixed between the blanking device and the sealing device, and the bottom end of the weighing sensor is connected to the The top end of the adjustment mechanism is fixedly connected, and the bottom end of the bag clamping mechanism is fixedly connected with the top end of the load cell; the adjustment mechanism includes a left and right adjustment bracket and a front and rear adjustment bracket, and the left and right adjustment brackets and the front and rear adjustment brackets are adjusted by screws Cooperate with each other; the bag clamping mechanism includes a fixed seat, a fixed plate, an adjustment screw, a claw opening motor, and a claw support arm. There are two fixed seats, which are respectively fixed at the two ends of the fixed plate, and the adjustment screw It is fixed between the two fixed seats through threaded connection, and the claw opening motor and the fixed plate are fixed through threaded connection; the bag clamping mechanism also includes a bag clamping claw, and the bag clamping claw is fixed on the front end of the claw support arm. Cooperate with claw opening motor.

The bag-feeding type online real-time metering automatic packaging machine provided by the present invention has the beneficial effect that: after a feeding screw is finished, the rotating large plate drives the bag to the next station, and the real-time metering device controls the bag clamping through the claw opening motor. The mechanism grasps the bag, and at the same time, the bag clamping device releases the bag, and the weighing sensor measures; after the weighing sensor completes the measurement, the bag clamping device clamps the bag, and the real-time measuring device controls the bag clamping mechanism to release the bag through the claw opening motor, and rotates The large plate continues to rotate, and the bag is taken to the next station. If the weight of the material does not meet the required weight requirement, the secondary blanking screw will perform secondary blanking to supplement the missing weight; if the material reaches the required weight requirement, the large plate will continue to rotate, and the measurement will be more accurate while ensuring the production efficiency. accurate.
