Specifically, a cam or cam is installed on the main rotating shaft 11 to transmit reciprocating swinging motion.

[0026] In this embodiment, Figure 6 As shown, it also includes a bag opening device 6, which includes an opening swing mechanism 61 and a bag opening mechanism 62. The opening swing mechanism 61 includes a first opening swing arm 611, a first opening pull rod 612 and a second opening swing arm 613.

[0027] The opening principle is as follows: the bag receiving device 3 clamps the packaging bag from the bag taking device 2, places it in the bag opening mechanism 62, and applies suction force to the bag opening through the opening vacuum suction cup, thereby opening the bag opening. Under the action of the opening swing mechanism 61, the bag opening mechanism 62 realizes the outer opening member 621 and the inner opening member 622 to retract and expand.

[0028] In this embodiment, Figure 7-8As shown, the bag taking device 2 also includes a bag taking support plate 23 installed on the frame 100, and a bag taking slide rail 24 is arranged on the bag taking support plate 23, and a limit plate 25 is installed on the bag taking support plate 23, and an arc groove 251 is arranged on the limit plate 25; the bag taking rotating mechanism 22 includes a bag taking slider 221, a pulley 222 and a bag taking frame 223, and the bag taking slider 221 is slidably connected with the bag taking slide rail 24; the bag taking frame 223 is connected with the pulley 222 through a connecting rod 224, and the pulley 222 is located in the arc groove 251. The function of the bag taking rotating mechanism 22 is to take the packaging bag from the storage rack. Figure 5 .

[0029] The bag taking rack 223 is provided with a plurality of bag taking vacuum suction cups, which are used to suck the packaging bags on the storage rack. The bag taking vacuum suction cups are directly obtained from the prior art, and the number of the vacuum suction cups is preferably more than four.

One end of the second bag picking pull rod 214 is connected to the bag picking rotating mechanism 22, and the other end thereof is hinged to the second bag picking swing rod 212.

[0031] The arc groove 251 in the present application is approximately "L" shaped, that is, when the bag taking frame 223 moves up and down, the bag taking pulley 222 also moves horizontally; since the bag taking frame 223 is connected to the bag taking pulley 222 through a connecting rod 224, when the bag taking pulley 222 is in the arc groove 251, the angle of the connecting rod 224 will change, and at the same time drive the bag taking frame 223 to flip, that is, the shape of the arc groove 251 controls the flipping angle of the bag taking frame 223; the bag taking pulley 222, the arc groove 251 and the connecting rod 224 together constitute the angle adjustment unit of the bag taking frame 223. Its purpose is to change the packaging bag taken in the horizontal direction into the vertical direction, so as to facilitate the clamping of the bag receiving mechanism, so as to enter the next process.

[0032] In this embodiment, Figure 9-10 As shown, the first bag receiving swing mechanism 31 includes a first bag receiving lower swing arm 311, a first bag receiving pull rod 312 and a first bag receiving upper swing arm 313, one end of the first bag receiving pull rod 312 is connected to the first bag receiving lower swing arm 311, and the other end thereof is connected to the first bag receiving upper swing arm 313; the upper end and the lower end of the first bag receiving upper swing arm 313 are respectively connected to the first bag receiving upper rod 314 and the first bag receiving lower rod 315, one end of the first bag receiving upper rod 314 is respectively connected to one of the upper splints 331, and one end of the first bag receiving lower rod 315 is respectively connected to the other upper splint 331.

[0035] It should be noted that the function of the lower bag receiving mechanism 34 is to clamp the packaging bag and drive the packaging bag to move from one workstation to the next workstation, while the function of the upper bag clamping mechanism 33 is to clamp the two ends of the top edge of the packaging bag delivered by the lower bag receiving mechanism 34, so that the packaging bag stays on the workstation and can be filled and other operations, and then transported to the next workstation by the lower bag receiving mechanism 34.

[0036] In this embodiment, the transverse reciprocating mechanism 35 includes a third bag-receiving swinging mechanism 351, and the output end of the driving mechanism 1 transmits power to the third bag-receiving swinging mechanism 351 through a bag-receiving transmission mechanism 352; the third bag-receiving swinging mechanism 351 includes two third bag-receiving swing arms 3511 and two third bag-receiving pull rods 3512, and the third bag-receiving swing arms 3511 are connected to the output shaft of the bag-receiving transmission mechanism 352; one end of each of the third bag-receiving pull rods 3512 is connected to the lower connecting plate 341, and the other end thereof is hinged to the third bag-receiving swing arm 3511.

[0037] It should be noted that the function of the bag receiving transmission mechanism 352 is to convert the rotational force of the output shaft of the driving mechanism 1 into the power for the third bag receiving swing arm 3511 to swing. The bag receiving transmission mechanism 352 specifically realizes power transmission and reversing through a gear set, and the gear set can specifically be a combination of spur gears and bevel gears.

[0038] In this embodiment, Figure 13-14As shown, one end of the cylinder 511 of the sealing swing mechanism 51 is hinged to the head of the sealing upper swing arm 512; each sealing mechanism 52 includes an outer sealing block assembly 521 and an inner sealing block assembly 522, and the upper and lower ends of the tail of each sealing upper swing arm 512 are respectively connected to the first sealing upper pull rod 517 and the first sealing lower pull rod 518, one end of the first sealing upper pull rod 517 is respectively connected to the outer sealing block assembly 521, and one end of the first sealing lower pull rod 518 is respectively connected to the inner sealing block assembly 522.

[0040] The present technical solution adopts a heat sealing method, that is, a heating module is provided on both the outer sealing block assembly 521 and the inner sealing block assembly 522. When the outer sealing block assembly 521 and the inner sealing block assembly 522 clamp the packaging bag, heat sealing is achieved. The role of the cylinder 511 here is that the length of the cylinder 511 can be adjusted. When the length changes, the spacing between the outer sealing block assembly 521 and the inner sealing block assembly 522 in the clamping state is different. In this way, whether to seal can be controlled. For example, when the previous bag connecting and filling actions are not completed ideally, the length of the cylinder 511 is changed to achieve the purpose of not sealing.

[0041] In addition, the cylinder 511 can also be used as a driving mechanism, and the actuator of the cylinder 511 can reciprocate up and down, thereby driving the sealing upper swing arm 512 to reciprocate; in this case, the sealing device does not need power from the driving mechanism 1.

The flattening rod 71, the flattening member 72 and the flattening smooth rail 73 are all provided with two pairs of two groups. The flattening mechanism 7 flattens the bag body of the filled packaging bag to facilitate the sealing operation of the next station. The above are only preferred specific implementations of the present invention; however, the protection scope of the present invention is not limited thereto.
