[0082] like Figures 1 to 23 As shown, an embodiment of the present invention provides a fully automatic bagging packaging machine, including a frame A, a cabinet and a cabinet door are provided on the frame A, and a controller for controlling the operation of the entire fully automatic packaging machine is also provided on the cabinet. On one side of the frame A, a tube film conveying mechanism 2, a film moving mechanism 3, a film pulling mechanism 4, a sealing and cutting mechanism 5, a bag feeding mechanism 6, a supporting mechanism 8, a bag receiving mechanism 7, and a bag opening and sealing mechanism 9 are provided. On the other side of the frame A, a feeding mechanism 10 is provided. The frame A preferably includes two parts, and the two parts adopt a detachable design to facilitate the installation of the above-mentioned mechanisms.

[0083] The tubular film is wound on the tubular film conveying mechanism 2, and the tubular film conveying mechanism 2 conveys the tubular film to the film walking mechanism 3, the film pulling mechanism 4 and the sealing and cutting mechanism 5 in sequence. The sealing and cutting mechanism 5 completes the sealing and cutting of one end of the tubular film to form packaging bags with only a single opening. The bag feeding mechanism 6 conveys the packaging bag to the bag receiving mechanism 7, and the bag receiving mechanism 6 conveys the packaging bag to the bag opening and sealing mechanism 9. The bag opening and sealing mechanism 9 can complete the opening and sealing of the packaging bag. When the bag opening and sealing mechanism 9 opens the bag, the supporting mechanism 8 supports the main part of the packaging bag. The feeding mechanism 10 conveys the material to be packaged into the packaging bag. After the feeding mechanism 10 completes feeding, the bag opening and sealing mechanism 9 seals the bag opening of the packaging bag.

[0084] A fully automatic bagging packaging machine provided in an embodiment of the present invention is aimed at items that have already been packaged in a layer of packaging bags, and performs secondary packaging of bags within bags, realizing automatic film feeding, bag making, bag opening, material feeding, and sealing packaging, completing the entire bagging packaging, realizing fully automatic bagging packaging, requiring no manpower, and improving packaging efficiency.

[0085] like Figure 3 and 20 As shown, in the embodiment of the present invention, the feeding mechanism 10 includes a feeding base plate 101, a feeding slide plate 102 is slidingly provided on the feeding base plate 101, a feeding rack 103 is provided on the feeding slide plate 102, and a feeding belt 104 is provided on the feeding rack 103; when feeding, the feeding slide plate 102 moves along the negative direction of the first direction X, so that one end of the feeding rack 103 extends into the packaging bag, and at the same time, the material to be packaged is transported on the feeding belt 104, and the feeding belt 104 moves along the negative direction of the first direction X; when the material to be packaged is about to fall into the packaging bag from the end of the feeding rack 103, the feeding rack 103 moves along the positive direction of the first direction X, and at the same time, the feeding belt 104 continues to move along the negative direction of the first direction X, and the speed of the feeding rack 103 is equal to the speed of the feeding belt 104. In the embodiment of the present invention, after the bag opening and sealing mechanism 9 opens the packaging bag (hereinafter referred to as the outer bag), one end of the feeding rack 103 moves and extends into the packaging bag, and the extending position is close to the bottom of the packaging bag. Then the feeding belt 104 also transports the packaging bag that has been packaged with one layer (hereinafter referred to as the inner bag) into the outer bag along the negative direction of the first direction X. When the inner bag is about to fall from the feeding rack 103 into the outer bag, the feeding rack 103 moves along the positive direction of the first direction X. The speed of the feeding rack 103 is equal to the speed of the feeding belt 104. At this time, the inner bag containing the items falls into the outer bag in a horizontally stationary state, completing the insertion of the inner bag into the outer bag. This can prevent the inner bag and the outer bag from rubbing in the horizontal direction, thereby damaging the inner bag and the outer bag.

[0086] like Figure 20 As shown, a feeding slide rail 1011 is also provided on the feeding base plate 101, and the feeding slide rail 1011 extends along the first direction X. A feeding slider 1012 is slidingly provided on the feeding slide rail 1011, and the feeding slider 102 is provided on the feeding slider 1012. A feeding driving wheel 105 is provided on the side close to the feeding slide rail 1011, and a feeding driven wheel 106 is provided on the other side close to the feeding slide rail 1011. A feeding conveyor belt 107 is sleeved between the feeding driving wheel 105 and the feeding driven wheel 106, and the feeding conveyor belt 107 is connected to the bottom of the feeding slider 102. A first feeding drive unit 108 is also provided on the bottom plate, and the output end of the first feeding drive unit 108 is connected to the feeding driving wheel 105. Specifically, the first feeding drive unit 108 is a driving motor, which drives the feeding active wheel 105 to rotate, so that the feeding conveyor belt 107 can move between the feeding active wheel 105 and the feeding driven wheel 106, and the feeding conveyor belt 107 drives the feeding slide 102 to move back and forth along the first direction X, so that the feeding rack 103 can move back and forth along the first direction X.

[0087] like Figure 20 As shown, a feeding support plate 1031 is provided on the feeding slide 102, and the feeding rack 103 is connected to the feeding support plate 1031. The two ends of the feeding rack 103 are respectively rotatably provided with a feeding active shaft 1010 and a feeding driven shaft 1011. The feeding belt 104 is sleeved between the feeding active shaft 1010 and the feeding driven shaft 1011. A second feeding drive unit 1012 is provided on one side of the feeding rack 103, and the output end of the second feeding drive unit 1012 is connected to the feeding active shaft 1010. Specifically, the second feeding drive unit 1012 is a driving motor, which drives the feeding active shaft 1010 to rotate through the second feeding drive unit 1012, so that the feeding belt 104 can rotate between the feeding active shaft 1010 and the feeding driven shaft 1011, and the items with inner bags can move on the feeding belt 104. It should be noted that a feeding load-bearing plate (not shown) is provided in the middle of the feeding belt 104 to support the load.

[0088] like Figure 3 and 4 As shown, the cylindrical film conveying mechanism 2 includes a film winding device 21, which includes two sets of film winding supports 211. A film winding rod 212 is rotatably disposed between the two sets of film winding supports 211. A film winding roller 213 is sleeved on the film winding rod 212, and the cylindrical film is wound around the film winding roller 213. Specifically, the cylindrical film is wound around the film winding supports 211 and is pulled by the film pulling mechanism 4 so that the cylindrical film is fed to the film feeding mechanism 3.

[0089] like Figure 4 As shown, in order to facilitate the winding of the rolled tube film on the film rolling roller 213 and maintain the stable rotation of the film rolling roller 213, the film rolling support part 211 includes a film rolling lower seat 2111 and a film rolling upper seat 2112, one end of the film rolling lower seat 2111 is rotatably connected to one end of the film rolling upper seat 2112, and two groups of lower film rolling support wheels 21111 are rotatably provided on the film rolling lower seat 2111, and two groups of upper film rolling support wheels 21121 are rotatably provided on the film rolling upper seat 2112. Both ends of the film rolling rod 212 are provided with film rod support wheels 2121, and the film rod support wheels 2121 are clamped between the upper film rolling support wheel 21121 and the lower film rolling support wheel 21111, and the other end of the film rolling lower seat 2111 is provided with a lock buckle 2113, and the film rolling upper seat 2112 is provided with a lock groove 21122 corresponding to the lock buckle 2113. Specifically, when the rolled tube film needs to be wound on the film rolling roller 213, the lock buckle 2113 and the lock groove 21122 remain separated. At this time, the film rolling lower seat 2111 and one end of the film rolling upper seat 2112 are rotated, so that the film rolling upper seat 2112 is opened, and the film rolling roller 213 is taken out to roll the tube film on the film rolling roller 213. After completion, the film rolling rod 212 is placed on the film rolling lower seat 2111 again, and the film rolling upper seat 2112 is rotated and locked in the lock groove 21122 by the lock buckle 2113, so that the film rolling upper seat 2112 and the film rolling lower seat 2111 are locked, and the film rod support wheel 2121 rotates and is clamped between the two groups of lower film rolling support wheels 21111 and the two groups of upper film rolling support wheels 21121. When the film is fed, the film rolling roller 213 can maintain stable rotation.

[0090] During packaging, the tube film stops conveying and continues conveying after packaging is completed. In order to keep the film roll 213 synchronously conveyed intermittently during conveying, Figure 4As shown, the tubular film conveying mechanism 2 also includes a tubular film driving device 22, and the tubular film driving device 22 includes a first tubular film driving mounting plate 221 and a second tubular film driving mounting plate 222, and the first tubular film driving mounting plate 221 and the second tubular film driving mounting plate 222 are both provided with a tubular film bearing seat 223, and a tubular film linkage rod 224 is rotatably provided on the two tubular film bearing seats 223, and a tubular film driving cylinder 225 is provided on the first tubular film driving mounting plate 221, and the output end of the first tubular film driving cylinder 225 is rotatably provided with a first tubular film linkage plate 226, and the first tubular film linkage plate 226 is connected to the tubular film linkage rod 224, and a second tubular film linkage plate 227 is also provided on the tubular film linkage rod 224, and a tubular film driving motor 228 is provided on the second tubular film linkage plate 227, and the output end of the tubular film driving motor 228 is connected to a tubular film pressing wheel 229, and the tubular film pressing wheel 229 can press on the tubular film wound on the film winding roller 213. Specifically, when the film rolling roller 213 needs to rotate for transportation, the film driving cylinder 25 drives the first film linkage plate 226 to swing, and the first film linkage plate 226 drives the film linkage rod 224 to rotate, and the film linkage rod 224 drives the second film linkage plate 227 to swing, which will make the film pressure wheel 229 close to the film wound on the film rolling roller 213, and then the film driving motor drives the film pressure wheel 229 to rotate, and the film pressure wheel 229 drives the entire film rolling roller 213 to rotate to transport the film; when it is necessary to stop transporting, the film driving cylinder 225 retracts, so that the film pressure wheel 229 does not contact the film, that is, stops the transport of the film, and cooperates with the packaging process. Furthermore, the tubular film is wound on the film winding roller 213, and as it is continuously conveyed, the thickness of the tubular film becomes thinner. The rotation angle of the tubular film linkage rod 224 driven by the tubular film driving cylinder 225 is variable. Therefore, no matter how thick or thin the tubular film is wound on the film winding roller 213, the tubular film pressure wheel 229 can be tightly attached to the outer side of the tubular film wound on the film winding roller 213 when conveying the tubular film, thereby ensuring normal and stable transportation of the tubular film.

[0091] In order to keep the tubular film taut during transportation and ensure that the sealing and cutting mechanism 5 does not wrinkle the tubular film during sealing and cutting, Figure 3 and 5As shown, the film feeding mechanism 3 includes two groups of film feeding mounting plates 31, a plurality of film feeding fixing rods 32 are arranged between the two groups of film feeding mounting plates 31, and a first film feeding roller 33, a second film feeding roller 34, a third film feeding roller 34, a fourth film feeding roller 36, a fifth film feeding roller 37, and a sixth film feeding roller 38 are rotatably arranged between the two groups of film feeding mounting plates 31. The first film feeding roller 33 is located at the top of the film feeding mounting plate 31, close to the side of the tube film conveying mechanism 2, and the second film feeding roller 34 is located at the bottom of the film feeding mounting plate and is located at the The first film feed roller 33 is located below the first film feed roller 33, the third film feed roller 34 is located next to the first film feed roller 33, the fourth film feed roller 36 is located below the third film feed roller 34, the fifth film feed roller 37 is located on the top of the film feed mounting plate 31 on the side away from the tubular film conveying mechanism 2, and the sixth film feed roller 38 is located below the fifth film feed roller 37. The tubular film passes through the first film feed roller 33, the second film feed roller 34, the third film feed roller 34, the fourth film feed roller 36, the sixth film feed roller 38, and the fifth film feed roller 37 in sequence. Specifically, when the tubular film is conveyed from the film winding roller 213 to the film stretching mechanism 4, the tubular film passes through the first film feed roller 33, the second film feed roller 34, the third film feed roller 34, the fourth film feed roller 36, the sixth film feed roller 38, and the fifth film feed roller 37 in sequence, so that the tubular film remains taut before entering the film stretching rollers, ensuring that the tubular film will not wrinkle when being sealed and cut by the sealing and cutting mechanism 5.

[0092] like Figure 3 、 6 As shown in Figure 7, the film-stretching mechanism 4 includes two groups of film-stretching mounting plates 41, and an upper film-stretching roller 42 and a lower film-stretching roller 43 are rotatably arranged between the two groups of film-stretching mounting plates 41. The upper film-stretching roller 42 is detachably connected to the film-stretching mounting plates 41, and the upper film-stretching roller 42 can press the tubular film tightly against the lower film-stretching roller 43. A film-stretching driven wheel 431 is arranged on one side of the lower film-stretching roller 43, and a film-stretching driving motor 44 is arranged on the film-stretching mounting plate 41 near the film-stretching driven wheel 431. A film-stretching driving motor 44 is arranged on the output end of the film-stretching driving motor 44, and a film-stretching driving wheel 441 is arranged, and a film-stretching belt 442 is arranged between the film-stretching driving wheel 441 and the film-stretching driven wheel 431. Specifically, in this embodiment, when the tubular film is being transported, it passes between the upper film-stretching roller 42 and the lower film-stretching roller 43, and the film-stretching driving motor 44 drives the film-stretching active wheel 441 to rotate. The film-stretching active wheel 441 drives the film-stretching driven wheel 431 to rotate through the film-stretching belt 442, and the film-stretching driven wheel 431 drives the lower film-stretching roller 43 to rotate, so that the tubular film is transported to the sealing and cutting mechanism 5 for sealing and cutting.

[0093] like Figure 6 and 7As shown, a film-drawing guide roller 45 is rotatably provided on one side near the film-drawing mechanism 3 between the two groups of the film-drawing mounting plates 41, and the film-drawing guide roller 45 is used to guide the tubular film from the film-drawing mechanism 3 to be transported between the upper film-drawing roller 42 and the lower film-drawing roller 43, so that the tubular film enters between the upper film-drawing roller 42 and the lower film-drawing roller 43 in a horizontal manner. A film-drawing fixing frame 46 is also provided between the two groups of the film-drawing mounting plates 41, and a first film-drawing guide frame 461 and a second film-drawing guide frame 462 are provided on the film-drawing fixing frame 46. The first film-drawing guide frame 461 is provided with several groups, and the first film-drawing guide frame 461 is provided on one side of the entrance of the lower film-drawing roller 43. The first film-drawing guide frame 461 includes a first film-drawing connecting plate 4611, a first film-drawing guide plate 4612 and a second film-drawing guide plate 4613. The lower film-drawing roller 43 is provided with several film-drawing guide grooves 47. 4611 is connected to the film-stretching fixing frame 46, the first film-stretching guide plate 4612 is arc-shaped, the first film-stretching guide plate 4612 can be embedded in the film-stretching guide groove 47, the second film-stretching guide plate 4613 is connected to the top of the first film-stretching guide plate 4612, the second film-stretching guide plate 4613 is horizontal, the second film-stretching guide frame 462 is arranged on the side close to the outlet of the lower film-stretching roller 43, the second film-stretching guide frame 462 includes a second film-stretching connecting plate 4621 and a third film-stretching guide plate 4622, the bottom of the second film-stretching connecting plate 4621 is connected to the film-stretching fixing frame 46, the third film-stretching guide plate 4622 is connected to the top of the second film-stretching connecting plate 4621, the third film-stretching guide plate 4622 extends toward the lower film-stretching roller 43, and the third film-stretching guide plate 4622 is located below the second film-stretching guide plate 4613. Specifically, through the cooperation of the film-drawing guide groove 47, the first film-drawing guide plate 4612, and the second film-drawing guide plate 4613, the second film-drawing guide plate 4613 is tangent to the circular surface of the lower film-drawing roller 43. This allows the tubular film to be output in a horizontal manner at the exit of the upper film-drawing roller 42 and the lower film-drawing roller 43, ensuring that the tubular film will not wrinkle and will remain horizontal and flat during sealing and cutting. Furthermore, one end of the third film-drawing guide plate 4622 serves as a support and connection, allowing the tubular film to smoothly enter the sealing and cutting mechanism 5. The other end of the third film-drawing guide plate 4622 extends downwardly and tilted to the bottom of the second film-drawing guide plate 4613. The tubular film can remain horizontally supported at the top of the third film-drawing guide plate 4622 and will not roll up at the exit of the upper film-drawing roller 42 and the lower film-drawing roller 43.

Specifically, in this embodiment, the first upper heat sealing plate 512 corresponds to the first lower heat sealing plate 522, and the second upper heat sealing plate 513 corresponds to the second lower heat sealing plate 523. When the tubular film is conveyed between the upper sealing and cutting device 51 and the lower sealing and cutting device 52, the first upper heat sealing plate 512, the second upper heat sealing plate 513 and the first lower heat sealing plate 522 and the second lower heat sealing plate 523 are closed together to complete the heat sealing of the bottom of the packaging bag. After the heat sealing is completed, the sealing and cutting knife 525 moves along the second direction Y to cut the packaging bag to form a packaging bag that is sealed on three sides and has only one opening.

[0095] like Figure 8As shown, the upper sealing and cutting device 51 also includes an upper sealing and cutting gantry 511, the top of which is provided with an upper sealing and cutting driving cylinder 5111, the output end of which is connected to an upper sealing and cutting mounting plate 5112, upper sealing and cutting slide rails 5113 are provided on both sides of the upper sealing and cutting gantry 511, upper sealing and cutting sliders 5114 are slidably provided on the upper sealing and cutting slide rails 5113, the upper sealing and cutting sliders 5114 are connected to the upper sealing and cutting mounting plate 5112, a plurality of upper sealing and cutting rods 5115 are slidably provided on the upper sealing and cutting mounting plate 5112, the bottom of the upper sealing and cutting rods 5115 are connected to the first upper heat-sealing plate 512 or the second upper heat-sealing plate 513, and an upper sealing and cutting spring 5116 is sleeved on the upper sealing and cutting rods 5115. Specifically, in this embodiment, the upper sealing and cutting driving cylinder 5111 drives the upper sealing and cutting mounting plate 5112 to slide on the upper sealing and cutting slide rail 5113, and the upper sealing and cutting mounting plate 5112 drives the first upper heat-sealing plate 512 and the second upper heat-sealing plate 513 to move up and down along the third direction Z. An upper sealing and cutting sleeve rod and an upper sealing and cutting spring 5116 are provided between the upper sealing and cutting mounting plate 5112 and the first upper heat-sealing plate or the second upper heat-sealing plate. The upper sealing and cutting spring 5116 can ensure that the first upper heat-sealing plate 512 and the second upper heat-sealing plate 513 are in contact with the first lower heat-sealing plate 522 and the second lower heat-sealing plate 523 when an elastic force is applied, thereby preventing the service life of the upper sealing and cutting device 51 and the lower sealing and cutting device 52 from being shortened due to hard contact.

[0096] like Figure 9 and 10 As shown, the lower sealing and cutting device 52 includes a lower sealing and cutting gantry 521, a lower sealing and cutting driving cylinder 5211 is provided at the bottom of the lower sealing and cutting gantry 521, the output end of the lower sealing and cutting driving cylinder 5211 is connected to a first lower sealing and cutting connecting plate 5212, the first lower sealing and cutting connecting plate 5212 is connected to the second lower heat-sealing plate 523, and both sides of the first lower heat-sealing plate 522 are connected to the second lower heat-sealing plate 523.

Since the sealing and cutting knife 525 passes through the lower sealing and cutting groove 524 and the upper sealing and cutting groove 514, when the sealing and cutting knife 525 moves along the second direction Y, it can cut the tubular film that has been heat-sealed.

[0098] like Figure 3 、 11As shown in FIG12 , after the sealing and cutting mechanism 5 completes the sealing and cutting, the sealed and cut packaging bags need to be towed away for bag delivery for subsequent bag opening and sealing. The bag delivery mechanism 6 is used to deliver the tubular film from the sealing and cutting mechanism 5 to the bag opening and sealing mechanism 9. It should be noted that the sealing and cutting mechanism 5 performs the heat sealing and cutting steps only after the bag delivery mechanism 6 delivers the tubular film from one side of the sealing and cutting mechanism 5 to the side near the bag opening and sealing mechanism 9, thereby ensuring the continuity of bag delivery and sealing and cutting. The bag feeding mechanism 6 includes a bag feeding mounting frame 61, and two sets of first bag feeding slide rails 62 arranged side by side are provided on the bag feeding mounting frame 61.
