[0004] The intelligent cartoon-shaped packaging machine has the problems of large floor space and the finished special-shaped bags being scattered in disorder and needing to be arranged manually or by equipment when being sent out. UTILITY MODEL CONTENTS

[0005] The utility model aims at providing a special-shaped bag filling and packaging machine which can reduce the floor space and quickly complete the taking out and flat laying of the finished special-shaped bags. The technical scheme adopted is as follows:

[0006] The application discloses a special-shaped bag filling and packaging machine, which comprises a rack and a film feeding and cutting and folding mechanism, a material filling mechanism, a sealing and bag making mechanism, a film pulling mechanism and a shape trimming mechanism which are sequentially arranged along the film movement sequence and are respectively installed on the rack. The rack is provided with a filling station, a sealing station, a film pulling station and a trimming station, and the filling station, the sealing station, the film pulling station and the trimming station are sequentially arranged from top to bottom along the rack. The filling port of the material filling mechanism is arranged on the filling station, the sealing and bag making mechanism is arranged on the sealing station, the film pulling mechanism is arranged on the film pulling station, and the shape trimming mechanism is arranged on the trimming station.

The material filling mechanism fills the material into the top unsealed special-shaped bag semi-product processed by the bag making and heat sealing mechanism.

[0007] In a preferred embodiment, the special-shaped bag filling and packaging machine further comprises a finished product feeding mechanism, and the finished product feeding mechanism is a conveying belt which is arranged below the swing device and passes through the bag placing station.

[0008] In a preferred embodiment, the special-shaped bag filling and packaging machine further comprises a waste film collecting mechanism which is installed at the rear part of the rack and is arranged at the rear side of the shape trimming mechanism according to the film movement sequence.

[0009] In a more preferred embodiment, the film feeding and cutting and folding mechanism extends from right to left along the longitudinal direction of the rack, the filling station, the sealing station, the film pulling station and the trimming station are sequentially arranged from top to bottom along the rack, the outlet of the material filling mechanism is arranged on the filling station, the sealing and bag making mechanism is arranged on the sealing station, the film pulling mechanism is arranged on the film pulling station, and the shape trimming mechanism is arranged on the trimming station. The waste film collecting mechanism and the finished product feeding mechanism are sequentially arranged from rear to front along the transverse direction of the rack, and the material filling mechanism is arranged at the top rear side of the rack and above the waste film collecting mechanism.

[0010] In a more preferred embodiment, the special-shaped bag filling and packaging machine further comprises a control device which is electrically connected with the film feeding and cutting and folding mechanism, the material filling mechanism, the sealing and bag making mechanism, the film pulling mechanism, the shape trimming mechanism, the finished product feeding mechanism and the waste film collecting mechanism.

[0019] like Figures 1-6As shown, the shaped bag filling and packaging machine in one embodiment of the present application comprises a rack 1 and a film feeding and cutting and folding mechanism 2, a material filling mechanism 3, a sealing and bag making mechanism 4, a film pulling mechanism 5, and a shape trimming mechanism 6, which are respectively installed on the rack 1 and sequentially distributed along the film movement sequence. The rack 1 is provided with a filling station A, a sealing station B, a film pulling station C, and a trimming station D, and the filling station A, the sealing station B, the film pulling station C, and the trimming station D are sequentially arranged from top to bottom along the rack 1. The filling port of the material filling mechanism 3 is arranged on the filling station A, the sealing and bag making mechanism 4 is arranged on the sealing station B, the film pulling mechanism 5 is arranged on the film pulling station C, and the shape trimming mechanism 6 is arranged on the trimming station D. The cutter 601 of the shape trimming mechanism 6 has at least one point-shaped connecting groove 6011 on the cutting edge. A bag taking station E is arranged below the shape trimming mechanism 6, and a bag placing station F is arranged below the front side of the shape trimming mechanism 6. A finished product taking and placing mechanism 7 is further installed on the rack 1. The finished product taking and placing mechanism 7 comprises a swing device 701 and at least one vacuum suction cup 702. The swing device 701 is installed at the bottom of the rack 1, and all the vacuum suction cups 702 are installed on the swing device 701. The swing device 701 drives all the vacuum suction cups 702 to swing between the bag taking station E and the bag placing station F. The film feeding and cutting and folding mechanism 2 outputs the film 10, cuts the film 10 into two halves, folds the two halves, and then sequentially passes the folded film 10 through the sealing and bag making mechanism 4 for sealing and the shape trimming mechanism 6 for trimming to obtain the shaped bag finished product 11 (which is connected to the film by at least one connecting point). The material filling mechanism 3 fills the material into the top unsealed shaped bag semi-finished product processed by the sealing and bag making mechanism. Since the cutting edge of the cutter 601 has at least one point-shaped connecting groove 6011 (the number of the point-shaped connecting grooves 6011 in this embodiment is three), the shaped bag finished product is connected to the film by at least one connecting point after the shape trimming mechanism 6 finishes processing, and will not fall off the film. All the vacuum suction cups 702 of the finished product taking and placing mechanism 7 suck the shaped bag finished product at the bag taking station E and make it swing, thereby sequentially breaking the connecting points between the shaped bag finished product and the film. Only when the connecting points are broken, the shaped bag finished product will be separated from the film. When the swing device 701 drives all the vacuum suction cups 702 to swing to the bag placing station F, all the vacuum suction cups 702 stop working, and the shaped bag finished product in the flat state is placed down. In this way, the shaped bag finished product can be accurately placed on the bag placing station F (i.e., the shaped bag finished product is in a preset position and angle).

[0020] As Figure 4 , 5As shown, in an optional embodiment of this application, the frame 1 has a mounting side plate 101, and the swing device 701 includes a rotating shaft 70101, a swing rod 70102, a swing frame 70103, and a swing element 70104. The rotating shaft 70101 is mounted on the mounting side plate 101 and extends in a direction parallel to the film. The swing frame 70103 is mounted on the rotating shaft 70101, and all vacuum suction cups 702 are mounted on the swing frame 70103. The swing rod 70102 is mounted on one end of the rotating shaft 70101, and the swing element 70104 is mounted on the mounting side plate 101. The swing element 70104 is connected to the swing rod 70102 and drives the swing rod 70102 to rotate around the rotating shaft 70101, thereby driving all vacuum suction cups 702 to swing between the bag-taking station E and the bag-placing station F.

[0021] like Figure 4 As shown, in an optional embodiment of this application, the swing device 701 further includes an angle limiting unit 70105. The swing frame 70103 includes a swing side plate 701031, a bushing 701032, and a rotating shaft 701033. The swing side plate 701031 is fixed on the rotating shaft 70101. The bushing 701032 is installed at the end of the swing side plate 701031. The rotating shaft 701033 is rotatably disposed in the bushing 701032. The angle limiting unit 70105 includes a limiting rod 701051 and a limiting swing plate 701052. One end of the limiting swing plate 701052 is connected to one end of the rotating shaft 701033. The two ends of the limiting rod 701051 are respectively hinged to the other end of the limiting swing plate 701052 and the mounting side plate 101. The function of the angle limiting unit 70105 is to ensure that all vacuum suction cups 702 extend towards the film direction when the rotation shaft 701033 of the swing frame 70103 rotates to the front of the bag picking station E, so as to pick up the irregularly shaped bag product. When the rotation shaft 701033 of the swing frame 70103 rotates to the top of the bag placing station F, it ensures that all vacuum suction cups 702 extend vertically downward so as to place the irregularly shaped bag product.

[0022] like Figure 4 As shown in an optional embodiment of this application, the frame 1 further includes a pad 102, which is disposed at the bag-picking station E. This ensures that when the vacuum suction cup 702 picks up the bag, the irregularly shaped bag will not move outwards, facilitating bag picking by the vacuum suction cup 702.

[0023] like Figure 5 As shown, in one alternative embodiment of this application, the swing member 70104 is a cylinder, and the piston shaft of the cylinder is connected to the rocker arm 70102.

[0025] As Figure 1 , 2 As shown in the application one optional embodiment, the special-shaped bag filling packaging machine further comprises a waste film collecting mechanism 9, the waste film collecting mechanism 9 is installed at the rear of the rack 1 and the waste film collecting mechanism 9 is arranged at the rear side of the shape trimming mechanism 6 according to the sequence of film movement.

[0026] As Figure 1 , 2 As shown in the application one optional embodiment, the film feeding and cutting folding mechanism 2 extends from right to left along the longitudinal direction of the rack 1, the filling station A, the sealing station B, the film pulling station C and the trimming station D are arranged in sequence from top to bottom along the rack 1, the outlet of the material filling mechanism 3 is arranged on the filling station A, the sealing and bag making mechanism 4 is arranged on the sealing station B, the film pulling mechanism 5 is arranged on the film pulling station C, the shape trimming mechanism 6 is arranged on the trimming station D, the waste film collecting mechanism 9 and the finished product sending mechanism 8 are distributed in sequence from back to front along the transverse direction of the rack 1, the material filling mechanism 3 is arranged on the top rear side of the rack 1 above the waste film collecting mechanism 9. The longitudinal direction of the rack 1 is G direction, and the transverse direction is H direction.

[0027] As Figure 6 As shown in the application one embodiment, the special-shaped bag filling packaging machine further comprises a control device 12, the control device 12 is electrically connected with the film feeding and cutting folding mechanism 2, the material filling mechanism 3, the sealing and bag making mechanism 4, the film pulling mechanism 5, the shape trimming mechanism 6, the finished product sending mechanism 8 and the waste film collecting mechanism 9.

[0028] The working process will be introduced as follows: Figures 1-6

[0029] The control device 12 controls the work of each mechanism.

[0030] ​The film feeding and slitting folding mechanism 2 outputs the film on the right side, the film pulling mechanism 5 pulls the folded film 10 on the left lower side, the film feeding and slitting folding mechanism 2 feeds the film, cuts the film into two halves, folds the two halves, and then the folded film 10 is sequentially sealed by the sealing and bag making mechanism 4, trimmed by the shape trimming mechanism 6, and shaped into a bag product 11 (connected with the film by at least one connecting point). The material filling mechanism 3 fills the material into the top unsealed bag semi-product processed by the sealing and bag making mechanism 4. The product taking and placing mechanism 7 sucks the bag product 11 at the bag taking station E and makes the bag product 11 separate from the folded film 10, and then drives all the bag products 11 to swing to the bag placing station F, places the bag product 11 in a flat state, and accurately places the bag product 11 on the bag placing station F of the product feeding mechanism 8. The folded film 10 from which the bag product 11 is taken away is called waste film, which is collected by the waste film collecting mechanism 9.
