A bag supply component 100 is arranged near one side of the top of the machine body 1000, and the bag supply component 100 is located on one side of the bag-taking component 200.

[0027] Specifically, the whole fully servo packaging machine is mainly divided into eight processes: bag supply, bag taking, bag opening, bag opening detection, blanking into the bag, closing the packaging bag, rejecting empty bags, and sealing. After the bag-taking component 200 takes away the new packaging bag provided by the bag supply component 100, it will first blow air to open the bag to ensure that the packaging bag is in an open state, and then use a blowing block to detect and blow air again to ensure that the degree of bag opening is the same; after the bag opening is completed, the blanking into the bag step is completed in two times. First, a part is blanked, and then the second blanking is completed; then the bag filled with materials will be flattened and closed in the next step, and then empty bags will be detected and rejected, and finally sealed to complete the packaging. The transportation of the packaging bag is ensured by the transportation component 900 to move one by one workstations.

[0028] The bag supply component 100 includes a flap component 101 located on the front side of the machine body 1000, and a bag supply conveyor belt 102 is arranged on the front side of the flap component 101. The bag-taking component 200 includes a bag-taking suction cup 201 located on the front side of the machine body 1000, and a servo bag clamp 202 is arranged on the top of the bag-taking suction cup 201.

[0029] Specifically, the bag supply conveyor belt 102 transports the packaging bags, and the flap component 101 rotates continuously to stop the packaging bags at a fixed position. The bag-taking suction cup 201 rotates above the packaging bag to suck and take it away, and the servo bag clamp 202 clamps the new packaging bag. Thus, the bag-taking process is completed.

[0030] The bag-opening and air-blowing assembly 300 includes a lower bag-opening suction cup 301 located near one side of the front side of the machine body 1000. A left swing rod 302 is installed near the middle position of the front side of the machine body 1000. A right swing rod 306 is provided on the other side of the left swing rod 302. An air-blowing nozzle 303 for bag opening is provided between the left swing rod 302 and the right swing rod 306, and the air-blowing nozzle 303 for bag opening is installed on the machine body 1000. A short bag-unfolding block 304 and a long bag-unfolding block 305 are provided between the left swing rod 302 and the right swing rod 306, and the short bag-unfolding block 304 is located on one side of the long bag-unfolding block 305.

[0031] Specifically, the bag-feeding conveyor belt 102 transports the packaging bags. The paddle assembly 101 rotates continuously to stop the packaging bags at a fixed position. The bag-taking suction cup 201 rotates above the packaging bags to suck and take them away. The servo bag-clamping device 202 clamps a new packaging bag, thus completing the bag-taking process.

[0032] The transportation assembly 900 includes a conveyor plate 902 located near the other side of the front side of the machine body 1000. A bag-receiving spring-loaded claw 901 is provided on the conveyor plate 902. A conveyor guiding rod 903 is provided on the machine body 1000. A conveyor swing rod 904 is provided at the bottom of the conveyor guiding rod 903 near the other side. A servo motor A908 is provided near the other side of the front side of the machine body 1000. A lead screw 911 is fixedly installed at the shaft end of the power output shaft of the servo motor A908. A lead screw nut fixing seat 910 is movably connected to the outer periphery of the lead screw 911. A trolley pull rod 909 is movably installed on one side of the lead screw nut fixing seat 910. One end of the trolley pull rod 909 is movably connected to a trolley driving swing rod 912. The shaft end of the power output shaft of the servo motor A908 is rotatably connected to a short connecting rod 906 and a long connecting rod 907, and conveying swing rods 905 are movably installed at the ends of the short connecting rod 906 and the long connecting rod 907.

[0033] Specifically, during the process of transporting the packaging bags, the clamping method is to use two pairs of bag-receiving spring-loaded claws 901 to clamp both sides of the packaging bags. In this way, not only can the open-bag or closed-bag state of the packaging bags be maintained by a fixed distance, but also the width can be changed to realize the packaging of packaging bags with different bag widths. The conveyor swing rod 904 drives the conveyor plate 902 to move the position of the bag-receiving spring-loaded claw 901, and the moving distance can be accurately guaranteed to move between two adjacent workstations. After the bag-receiving spring-loaded claw 901 is moved to the previous workstation, the short connecting rod 906 and the long connecting rod 907 move in opposite directions, so that the opposite bag-receiving spring-loaded claws 901 clamp the packaging bags and are then carried into the next workstation, and so on.

[0034] Embodiment 2: This embodiment is an improvement made on the basis of Embodiment 1. Specifically, please refer to Figure 1, on one side of the L-shaped support 2000, a fixed groove 2001 is fixedly installed. On one side of the inner cavity of the fixed groove 2001, a servo motor B2002 is fixedly installed. And the shaft end of the power output shaft of the servo motor B2002 is fixedly installed with a threaded rod 2003. And the other end of the threaded rod 2003 movably penetrates through the adjacent L-shaped support 2000 and is rotatably connected to the L-shaped support 2000 that is far away. Threaded sleeves 2004 are threadedly connected to both ends of the outer periphery of the threaded rod 2003. And hinge rods 2005 are hinged to the bottoms of the threaded sleeves 2004. And the bottoms of the hinge rods 2005 are jointly hinged to a movable plate 2006. And universal wheels 2007 are fixedly installed near the four peripheries of the bottom of the movable plate 2006.

[0035] Specifically, by starting the servo motor B2002, the rotation of the power output shaft of the servo motor B2002 can cause the threaded rod 2003 to rotate. Opposite external threads are provided at both ends of the outer periphery of the threaded rod 2003. Thus, the threaded sleeves 2004 can move toward the opposite sides. Thus, the movable plate 2006 can move downward along a plurality of T-shaped limiting rods 2008. Thus, the universal wheels 2007 can contact the ground, facilitating the movement of the machine body 1000. On the contrary, the universal wheels can be lifted to improve the stability of the use of the machine body 1000.

[0036] Through holes are provided near the four peripheries of the top of the movable plate 2006. And T-shaped limiting rods 2008 movably penetrate through the inner cavities of the through holes. The bottom ends of the T-shaped limiting rods 2008 are fixedly connected to the adjacent L-shaped supports 2000 respectively.

[0037] Specifically, by providing the T-shaped limiting rods 2008 and the through holes, the movement of the movable plate 2006 can be limited.

[0038] Working principle: When this utility model is in use, the whole fully servo packaging machine is mainly divided into eight processes: bag feeding, bag taking, bag opening, bag opening detection, material falling into the bag, closing the packaging bag, empty bag rejection, and sealing. After the bag taking component 200 takes away the new packaging bag provided by the bag feeding component 100, it will first blow air into the bag to ensure that the packaging bag is in an open state. Then, it will use the air blowing block to detect and blow air again to ensure that the degree of bag opening is the same; after the bag opening is completed, the material falling into the bag step is completed in two times. First, a part of the material is dropped, and then the rest is dropped in the second time; then, the bag filled with materials will be flattened and closed in the next step. Then, the empty bags will be detected and removed, and finally, the sealing is completed to finish the packaging. The transportation of the packaging bags is ensured by the transportation component 900 for the movement of each work station;

[0039] The bag feeding conveyor belt 102 transports the packaging bags. The paddle component 101 will keep rotating to make the packaging bags stop at fixed positions. The bag taking suction cup 201 will rotate above the packaging bag, suck it and take it away. The servo bag clamping 202 will clamp the new packaging bag. Thus, the bag taking process is completed;

[0040] When the packaging bag is in place, the left swing rod 302 and the right swing rod 306 move in opposite directions, which will drive the short bag-expanding blocks 304 and the long bag-expanding blocks 305 on both sides to quickly contract inward. Coupled with the suction of the lower bag-opening suction cup 301 and the downward blowing of the bag-opening air nozzle 303, the bag-opening is thus realized. The bag-closing principle is similar to the bag-opening principle, except that the short bag-expanding blocks 304 and the long bag-expanding blocks 305 open outward to flatten the bag mouth of the packaging bag and realize bag-closing;

[0041] When clamping the packaging bag during the transportation process, two butt-joint bag-pressing spring claws 901 are used to clamp both sides of the packaging bag. In this way, not only can the bag-opening or bag-closing state of the packaging bag be maintained by a fixed distance, but also the width can be changed to realize the packaging of packaging bags with different bag widths. The conveying swing rod 904 will drive the conveying plate 902 to move the position of the butt-joint bag-pressing spring claw 901, and the moving distance can be accurately guaranteed to move between two adjacent workstations. After the butt-joint bag-pressing spring claw 901 is moved to the previous workstation, the short connecting rod 906 and the long connecting rod 907 move in opposite directions, so that the opposite butt-joint bag-pressing spring claws 901 clamp the packaging bag and are then carried into the next workstation, and so on;

[0042] The servo motor A908 drives the lead screw 911 to rotate, so that the lead screw nut fixing seat 910 will move, and then drives the trolley driving swing rod 912 to swing. Because the conveying swing rod 904 and the trolley driving swing rod 912 are coaxial, the conveying swing rod 904 will swing accordingly. By controlling the servo motor A908, the swing amplitude of the conveying swing rod 904 can be realized, so that the moving distance of the butt-joint bag-pressing spring claw 901 can be accurately guaranteed.

[0043] By starting the servo motor B2002, the rotation of the power output shaft of the servo motor B2002 can make the threaded rod 2003 rotate. Opposite external threads are provided near both ends of the outer periphery of the threaded rod 2003, so that the threaded sleeve 2004 can move to the opposite side, and then the movable plate 2006 can move downward on several T-shaped limiting rods 2008, and then the universal wheel 2007 can contact the ground to facilitate the movement of the machine body 1000. On the contrary, the universal wheel can be lifted to improve the stability of the use of the machine body 1000.
