[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0018] Please refer to Figures 1-3 , the semi-automatic bag packaging machine in this embodiment includes a frame 1 and a ladder 2. Two hemming sewing machines 3 are fixedly installed inside the frame 1. Two long belt conveyors 4 and two short belt conveyors 5 are fixedly installed inside the frame 1. Two pneumatic packaging mechanism racks 7 are fixedly installed inside the frame 1. Pneumatic bag clamping mechanisms 6 are fixedly installed at the bottoms of the two pneumatic packaging mechanism racks 7. A dust collector 8 is fixedly installed inside the frame 1. Two metering screw conveyors 9 are fixedly installed inside the frame 1. Four weighing sensors 10 are fixedly installed at the top of the frame 1. A buffer bin 11 is fixedly installed between the tops of the four weighing sensors 10. Four first cylinders 12 are fixedly installed at the top of the pneumatic packaging mechanism rack 7.

[0019] It should be noted that for the packaging of solid materials, especially the packaging of granular and powder materials, there are mainly problems such as cumbersome weighing, inaccurate metering, low filling efficiency, large loss, and large dust and dust emission. Through the cooperation among the frame 1, hemming sewing machine 3, long belt conveyor 4, short belt conveyor 5, pneumatic packaging mechanism rack 7, pneumatic bag clamping mechanism 6, etc. set above, a semi-automatic packaging machine can be formed. This semi-automatic packaging machine only requires manual bag sleeving and clamping, and the rest are automatically completed by the equipment, including processes such as conveying, dust removal, metering, packaging, hemming, and sealing. It adopts a double-line design and can work alternately, greatly improving the efficiency. The dust and dust generated during the packaging process can be recovered through the dust collector.

[0020] Specifically, before the packaging operation, the materials are loaded into the buffer bin 11. The weighing sensor 10 displays the weight of the materials in the bin in real time. Manually put the packaging bag on the frame 7 of the pneumatic packaging mechanism, and press the packaging start button. The pneumatic bag clamping mechanism 6 is driven by two double-acting cylinders 604 and a solenoid valve, and can be opened and clamped simultaneously. The pneumatic bag clamping mechanism 6 clamps the outer edge of the packaging bag, and the metering screw conveyor 9 starts to discharge materials. When it reaches 90% of the designed weight, the metering screw conveyor 9 reduces the frequency and speed until it stops discharging materials when the set weight is reached. The reduced weight of the bin is the bagging weight. The frame 7 of the pneumatic packaging mechanism moves downward under the drive of a cylinder 12, automatically opens the pneumatic bag clamping mechanism 6, and places the packaging bag filled with materials on the short belt conveyor 5. The short belt conveyor 5 starts and stops after sending the package to the long belt conveyor 4. The long belt conveyor 4 sends the upper opening of the packaging bag into the edge folding and sewing machine 3. The edge folding and sewing machine 3 moves synchronously and at the same speed as the long belt conveyor 4, and completes the edge folding and sealing of the packaging bag during the movement. When one line starts to convey and sew the bag, the other line can perform bagging and loading. The two lines operate alternately. At the same time, the dust generated during the packaging process is collected by the dust collector 8.

[0021] The pneumatic bag clamping mechanism 6 includes a blanking pipe 601, a fixed frame 602, a clamping rod 603 and a double-acting cylinder 604. The pneumatic bag clamping mechanism 6 includes a fixed frame 602 fixedly installed inside the pneumatic bag clamping mechanism 6. The blanking pipe 601 is fixedly installed inside the fixed frame 602. Two groups of clamping rods 603 are hingedly installed at the bottom of the fixed frame 602, and a double-acting cylinder 604 is fixedly installed between each group of clamping rods 603.

[0022] Specifically, the double-acting cylinder 604 drives the clamping rod 603 to open, and at this time, manual bagging operation can be carried out. The double-acting cylinder 604 drives the clamping rod 603 to close to clamp the packaging bag, and at this time, the discharging and bagging operation can be carried out.

[0023] To sum up, this small-bag semi-automatic packaging machine, through the cooperation between the edge folding and sewing machine 3, the long belt conveyor 4 and the pneumatic bag clamping mechanism 6, etc., puts the materials to be packaged into the buffer bin 11 during work. The buffer bin 11 is equipped with a weighing sensor 10, and the weighing sensor 10 can feedback the weight of the materials in the buffer bin 11 to the control system in real time. Only manual bag clamping is required, and the rest are completed automatically by the equipment, including processes such as conveying, dust removal, metering, packaging, edge folding and sealing. It adopts a double-line design and can work alternately, greatly improving the efficiency. And the dust and dust generated during the packaging process can be recycled through the dust collector, which can achieve high metering accuracy, small dust pollution, reduce the energy consumption of the original method, and effectively reduce the labor intensity of workers.
