[0002] The application prospect of high-performance and high-reliability packaging machinery in food and other packaging industries is very broad. Product packaging plays a very important role as a bridge between production and consumers, and the installation of food packaging is becoming more and more important.

[0003] The fully automatic bag-feeding packaging machine replaces manual packaging and realizes packaging automation for large and small enterprises. The operator only needs to put the prepared bags, hundreds of bags at a time, on the bag-taking part of the equipment. The equipment will automatically take the bags, print the date, open the bags, give the metering device a signal to measure, drop the materials, seal and output, which greatly improves the packaging efficiency of the products. However, the bag-feeding packaging machine for packaging chicken essence is relatively long in structure, and the whole process takes a long time to complete, and the production efficiency is low, which brings great economic losses to enterprises. Summary of the invention

[0006] frame,

[0007] An annular guide rail fixed on the frame;

[0008] A reduction motor is fixed on the bottom plate of the frame;

[0009] A main shaft arranged along the length direction of the frame is driven to rotate by the reduction motor;

[0010] Two main shaft support plates are fixed on the frame bottom plate, and the top of each main shaft support plate is provided with a circular hole to facilitate the main shaft to pass through and fix the main shaft to the frame bottom plate;

[0011] A bag clamping mechanism slidably mounted on the annular guide rail, comprising a plurality of clamping claws;

[0012] A bag loading mechanism disposed in the middle of the frame, located on one side of the annular guide rail, takes out the bag and delivers it to the clamping claw;

[0013] A bag-carrying mechanism for blanking is connected to the bag-carrying mechanism and is located on the same straight line;

[0016] A sealing mechanism is fixed on the frame and is arranged close to the blanking and bag-supporting mechanism;

[0017] A conveyor chain disposed on the frame, located below the sealing mechanism, for outputting the packaged finished products;

[0018] The bag loading mechanism, bag opening mechanism, bag holding mechanism and sealing mechanism are all connected to the main shaft.

[0019] Beneficial effects of the present invention:

[0020] The present invention uses a reduction motor to drive the bag loading mechanism, bag opening mechanism, bag blanking and bag supporting mechanism, and sealing mechanism to operate. The design is ingenious and energy-saving. The various working mechanisms of the present invention are designed tightly around the annular guide rail, and the bag loading mechanism and bag blanking and bag supporting mechanism are designed at both ends of the annular guide rail, and the same transmission shaft is used to drive the two mechanisms to move.

[0080] Working principle: The operator stacks the packaging bags horizontally on the pre-mounted rack 614, and the reduction motor 3 drives the main shaft 4 to rotate, and the first cam 601 installed on the main shaft 4 rotates, and the first transmission shaft 603 rotates in the vertical direction through the first connecting chain plate, and then transmits to the rack 606, so that the rack 606 makes a horizontal reciprocating motion, driving the lower suction cup 615 to suck the bags on the pre-mounted rack 614, and the upper bag gear 607 meshing with the rack 606 rotates, thereby driving the crankshaft 603 to rotate in the vertical direction. The handle 608 rotates, causing the two rods of the crank 608 to tilt toward the annular guide rail 2. The bag-loading cylinder 609 controls the bag clamping plate 611 to clamp the packaging bag and transport it to the clamping claw 5. The clamping claw 5 clamps the packaging bag. After the bag is clamped, the annular guide rail 2 is transported to the inkjet printer 11 station. After the date is printed, the clamping claw 5 shrinks and moves to the next station, i.e., the bag opening mechanism 8. The second cam fixed on the main shaft 4 moves, thereby driving the second transmission shaft 802 to rotate in the vertical direction. By pulling the connecting rod and the pull rod, the second cam 802 is pulled to rotate in the vertical direction. The plate 807 transmits power to the first suction cup tube and the second suction cup tube, and the bag mouth of the packaging bag is sucked open. After the bag is opened, it is transferred to the next station, that is, the material-dropping bag-supporting mechanism 7, which is arranged on the back of the bag-loading mechanism 6. The movement of the first transmission shaft 603 also drives the linkage rod 702 to move. The bag-supporting guide rod 705 pulls the opening and closing plate 706 to open the packaging bag, and the weighed material falls into the packaging bag. Then it is transferred to the next station, and the clamping claw 5 is stretched. The movement of the third cam drives the third transmission shaft The movement of 902 pulls the left support plate 904 and the right support plate 905 to move. The left support plate 905 drives the first and third electric heating plate seats to close, and the sealing rulers 908 on the two electric heating plate seats are also closed, completing the first sealing action. The clamping claw 5 continues to move forward, and the right support plate 905 drives the second and fourth electric heating plate seats to close, completing the secondary sealing. Then the clamping claw 5 is released, and the packaging bag filled with materials falls onto the conveyor chain 10 and is then conveyed out, completing a packaging cycle.

[0081] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
