[0034] The present invention will be further described in detail below with reference to the accompanying drawings.

[0035] As Figure 1As shown in the figure, a double-out large-packaging full-servo belt packaging system includes a body frame 1, a bag-taking mechanism 2, a traction mechanism 7, a bag-opening mechanism 8, a bag-squeezing mechanism 9, a feeding mechanism 10, an upper-sealing and pressing mechanism 11, and a shaping mechanism 12. The bag-taking mechanism 1 and the shaping mechanism 12 are respectively fixedly arranged at both ends of the body frame 1. The traction mechanism 7, the bag-opening mechanism 8, the bag-squeezing mechanism 9, the feeding mechanism 10, and the upper-sealing and pressing mechanism 11 are sequentially arranged between the bag-taking mechanism 1 and the shaping mechanism 12 from left to right. Among them, the bag-taking mechanism 1, the traction mechanism 7, the bag-opening mechanism 8, the bag-squeezing mechanism 9, the feeding mechanism 10, the upper-sealing and pressing mechanism 11, and the shaping mechanism 12 are all at the same horizontal height and are all installed on the body frame 1. The body frame 1 provides an installation cavity for the above-mentioned mechanisms.

[0036] As Figure 2 shown in the figure, the bag-taking mechanism 2 includes a base frame, a motor 21, a connecting rod assembly 22, a bag-taking rocker arm support 23, a bag-taking rocker arm 24, and a suction cup assembly 25. The motor 21 is fixedly arranged on one side of the base frame, and the bag-taking rocker arm support 23 is fixedly arranged on the other side of the base frame. One end of the bag-taking rocker arm 24 is rotatably connected to the end of the bag-taking rocker arm support 23 away from the base frame. The connecting rod assembly 22 includes a driving swing block 221 and a driving connecting rod 222. One end of the driving swing block 221 is fixedly connected to the rotating shaft of the motor 21, and the other end is rotatably connected to the driving connecting rod 222. The end of the driving connecting rod 222 away from the driving swing block 221 is rotatably connected to the bag-taking rocker arm 24. The suction cup assembly 25 is fixedly arranged at the end of the bag-taking rocker arm 24 away from the bag-taking rocker arm support 23. The suction cup assembly 25 includes a suction cup 251 and a suction cup support 252. The top of the suction cup support 252 is movably connected to the bag-taking rocker arm 24, and the suction cup 251 is arranged at the bottom of the suction cup support 252. The motor 21 drives the driving swing block 221 to swing, the driving swing block 221 drives the driving connecting rod 222 to move, the driving connecting rod 222 drives the bag-taking rocker arm 24 to rotate along the bag-taking rocker arm support 23, and the suction cup assembly 25 arranged at one end of the bag-taking rocker arm 24 moves in height to realize the adsorption of the packaging bag at the bottom. The connecting rod mechanism has a simple structure, is convenient for replacement and maintenance, and realizes long-distance transmission.

[0037] In order to make the suction cup support 252 keep the direction of the suction cup 251 vertically downward without external force drive. Therefore, in this embodiment, the suction cup support 252 and the bag-taking rocker arm 24 are eccentrically connected. The suction cup support 252 drives the suction cup 251 to be arranged along the direction of gravity by gravity. Along with the rotation of the bag-taking rocker arm support 23, the direction of the suction cup 251 does not change, which is convenient for the suction cup 251 to adsorb the packaging bag at the bottom.

[0038] In the prior art, packaging bags are generally placed horizontally. When filling is required, the packaging bag needs to be flipped so that the canning opening of the packaging bag is at the top. Therefore, in this embodiment, a flipping assembly 27 is provided between the bag-holding rocker arm bracket 23 and the suction cup assembly 25. The flipping assembly 27 includes a moving synchronous pulley 271 and a static synchronous pulley 272. The moving synchronous pulley 271 is coaxially rotatably arranged at one end of the bag-holding rocker arm bracket 23 with the bag-holding rocker arm 24, and the static synchronous pulley 272 is coaxially rotatably arranged at one end of the bag-holding rocker arm 24 with the suction cup bracket 252, and the static synchronous pulley 272 and the suction cup bracket 252 rotate synchronously. The moving synchronous pulley 271 and the static synchronous pulley 272 are driven by a synchronous belt 28. The moving synchronous pulley 271 is externally connected to a driving member, and the driving member drives the moving synchronous pulley 271 to rotate. In this embodiment, the externally connected driving member is a servo motor 21. The movement of the servo motor 21 is relatively stable, making the flipping action of the packaging bag more stable. The externally connected driving member drives the moving synchronous pulley 271 to rotate. The moving synchronous pulley 271 drives the static synchronous pulley 272 to rotate through the synchronous belt 28, and the static synchronous pulley 272 drives the suction cup bracket 252 to rotate, realizing the flipping of the packaging bag.

[0039] During the use of the synchronous belt 28, heat is generated by friction between the synchronous belt and the synchronous pulley, causing the synchronous belt 28 to be deformed by heat, resulting in stretching of the synchronous belt 28, reducing the friction force between the synchronous belt 28 and the synchronous pulley, causing relative slippage between the synchronous belt 28 and the synchronous pulley, and resulting in the failure of the suction cup assembly 25 to flip. Therefore, in this embodiment, an adjusting device 29 is provided at the position of the synchronous belt 28 on the bag-holding rocker arm 24. The adjusting device 29 includes an adjusting plate 291 and an adjusting nut 292. One end of the adjusting plate 291 is rotatably connected to the bag-holding rocker arm 24. An adjusting groove 2911 is formed on the surface of the adjusting plate 291. The screw rod of the adjusting nut 292 passes through the adjusting groove 2911 and is threadedly connected to the bag-holding rocker arm 24. One end of the adjusting plate 291 away from the rotating part is provided with a belt pressing rod 2912, and the side wall of the belt pressing rod 2912 abuts against the synchronous belt 28 to adjust the tightness of the synchronous belt 28.

[0040] In order to reduce the friction between the belt pressing rod 2912 and the synchronous belt 28, a roller 293 is provided between the belt pressing rod 2912 and the synchronous belt 28. The roller 293 is coaxially arranged with the belt pressing rod 2912, and the roller 293 and the synchronous belt 28 perform rolling friction.

[0041] In order to increase the longitudinal stroke of the suction cup 251 and make the suction cup 251 actively move to the surface of the packaging bag for adsorption, in the present embodiment, a bag picking cylinder 210 is fixedly provided on the suction cup bracket 252, and the suction cup 251 is fixedly provided at one end of the piston rod of the bag picking cylinder 210. The extension and retraction of the piston rod of the cylinder drives the suction cup 251 to move downward in the vertical direction, so that the suction cup 251 is in close contact with the packaging bag, thereby better adsorbing the packaging bag and avoiding accidental dropping of the packaging bag due to insufficient suction force of the suction cup 251.

[0042] like Figures 3 - 4 As shown, the traction mechanism 7 includes a driving component 71 and a clamping component. The driving component 71 cooperates with the clamping component to drive the packaging bag to move. The clamping component includes two parallel slide rails 721, a fixed frame 722, a connecting rod component 723, and a first screw module 724. The first screw module 724 is fixedly arranged on one side of the body base 1. The first screw module 724 is transmission-connected to the slide rail 721 through the connecting rod component 723. The fixed frame 722 is fixedly arranged on the other side of the body base 1. Rotating plates are respectively fixedly arranged at the bottom of the two slide rails 721, and the rotating plates and the fixed frame 722 are fixed by bolts for rotation.

[0043] The connecting rod assembly 723 includes a connecting rod 7231, a swing block 7232, a driving shaft 7233, a driving block 7234, a first transmission rod 7235, and a second transmission rod 7236.

The end of the swing block 7232 away from the connecting rod 7231 is fixedly connected to the driving shaft 7233. The swing block 7232 is fixedly arranged on the driving shaft 7233. The first transmission rod 7235 and the second transmission rod 7236 are rotatably connected to the two ends of the swing block 7232 respectively. The ends of the first transmission rod 7235 and the second transmission rod 7236 away from the swing block 7232 are rotatably connected to the rotating plate 725 respectively. When the motor in the first screw module 724 drives the screw to rotate, the slider in the first screw moves along the axial direction of the screw, and the slider drives the connecting rod 7231 to move along the axial direction of the screw, and the connecting rod 7231 drives the swing block 7232 to swing along the axial direction of the driving shaft 7233. The driving shaft 7233 swings and drives the driving block 7234 to swing. The driving block 7234 swings and drives the first transmission rod 7235 and the second transmission rod 7236 to move relative to each other, thereby changing the relative elongation of the first transmission rod 7235 and the second transmission rod 7236 with respect to the body base frame 1, thereby realizing the rotation of the rotating plate 725. The rotating plate 725 rotates to realize the opening and closing of the two slide rails 721, thereby finally realizing the clamping and fixation of the packaging bag.

[0044] The driving assembly 71 includes a second screw module 711, a module connecting rod 712, a first swing arm connecting rod 713, a swing arm 714, and a second swing arm connecting rod 715.

The swing arm 714 includes two parallel swing arms 7141, and a connecting plate 7142 is fixedly provided between the two swing arms 7141. In order to reduce the overall mass of the mechanism and reduce functional loss, process holes are opened on the surface of the swing arm 7141, and the number, size and shape of the process holes can be adjusted according to the length, width and thickness of the swing arm 7141.

[0045] One end of the second swing arm connecting rod 715 away from the swing arm 714 is rotatably connected to the slide rail 721, wherein the second screw module 711 drives the module connecting rod 712 to translate along the axial direction of the screw, the module connecting rod 712 drives the first swing arm connecting rod 713 to translate, the first swing arm connecting rod 713 drives the swing arm 714 to swing along the axial direction of the rotating shaft, the rotation of the swing arm 714 drives the slide rail 721 to move in the horizontal direction, and the driving component 71 cooperates with the clamping component to realize the long-distance movement of the packaging bag.

There are two second connecting rods 822, and the second connecting rods 822 are set along the height direction of the body frame 1. The two second connecting rods 822 are respectively rotatably connected to the other two ends of the triangular pendulum block 823. A driving pendulum block 84 is arranged between the first connecting rod 821 and the motor 81. One end of the driving pendulum block 84 is fixedly connected to the rotating shaft of the motor 81, and the other end is rotatably connected to the first connecting rod 821. The driving pendulum block 84 is driven by the motor 81 to swing back and forth. When the rotating shaft of the motor 81 rotates back and forth by a certain angle, the driving pendulum block 84 drives the triangular pendulum block 823 to swing through the first connecting rod 821.

In this embodiment, in order to increase the stability of the driving force, the motor 91 adopts a servo motor 91. The servo motor 91 realizes the closed-loop control of position, speed, and torque, and the servo motor 91 runs smoothly at low speed, and the dynamic response time of the motor 91 during acceleration and deceleration is short. The use method is more flexible and the operation is more stable, making the linkage mechanism 92 run more smoothly during transmission and facilitating the extrusion and opening of the packaging bag.

[0049] The linkage mechanism 92 includes a driving rod 921, a first connecting rod 922, a second connecting rod 923, a swing rod 924, a first swing block 925, and a second swing block 926.
