In the description of this utility model, it should be understood that the terms "upper," "lower," "front," "upper surface," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this utility model.

[0027] Please see Figure 1-10 The present invention provides an embodiment of a bag packaging machine, comprising a frame 1, a shelf 4 for placing bags on the frame 1, and a gripping component 6 below the shelf 4; the gripping component 6 grips the bag placed horizontally on the shelf 4 and rotates it to make the bag perpendicular to the frame 1; thus, the gripping component 6 can be used to rotate the horizontally placed bag so that the bag loading component 2 can transfer the bag;

[0028] The frame 1 is also provided with a bagging assembly 5, and an upper bag assembly 2 is provided between the bagging assembly 5 and the placement rack 4. The rotated bag is moved to the bagging assembly 5 through the upper bag assembly 2. Thus, the bagging assembly 5, the upper bag assembly 2 and the gripping assembly 6 can all be integrated on the upper surface of the frame 1, which ensures the smooth transfer of the bag while making full use of the space on the upper surface of the frame 1.

[0029] Specifically, the upper bag assembly 2 includes a first bracket 20, on which a first lead screw 22 is provided, and the first lead screw 22 is connected to a first cylinder 23 via a first lead screw seat 21. A first mounting frame 25 is installed on the working part of the first cylinder 23, and the first mounting frame 25 is provided with suction cups 24. Therefore, the upper bag assembly 2 uses the suction cups 24 to adhere to the side of the bag to prevent the bag from falling off during transportation. At least four suction cups 24 are installed on the first mounting frame 25 to increase the stability of the bag during transportation by increasing the number of suction cups 24.

[0030] To facilitate the smooth opening of the bag opening, the other side of the bagging assembly 5 is also provided with a clamping assembly 3 for clamping the side of the bag. When the clamping assembly 3 clamps the side of the bag, specifically, the clamping end of the clamping assembly 3 clamps the two sides of the bag away from the suction cup 24. The first cylinder 23 retracts, causing the suction cup 24 to open the bag opening, so that the material on the bagging assembly 5 can smoothly enter the bag.

[0031] In summary, after the suction cup 24 on the first mounting frame 25 adsorbs the bag, the first lead screw 22 drives the first mounting frame 25 to move, thereby moving the bag to the bagging assembly 5 for bagging. Therefore, the bag-loading assembly 2 of this equipment has the advantages of simple structure and few parts while completing the bag-loading action. In particular, as... Figure 1 As shown, the upper bag assembly 2 is installed on the left side of the bagging assembly 5, and the clamping assembly 3 is installed on the right side of the bagging assembly 5; then the gripping assembly 6 is installed on the side away from the bagging assembly 5. Finally, the gripping assembly 6 is used to grip the bag body, the upper bag assembly 2 is used to transfer the bag body, and the clamping assembly 3 is used to clamp the bag body so that the suction cup 24 on the upper bag assembly 2 can open the bag opening and the bagging assembly 5 can fill the bag. Based on this, the equipment can complete the bagging task while the overall structure of the equipment is compact, so as to reduce the space occupation of the equipment.

[0032] The gripping component 6 includes a support frame 60, on which a drive shaft 63 is rotatably mounted. The end of the drive shaft 63 facing the bag is connected to a second cylinder 66. A second mounting frame 65, with the same structure as the first mounting frame 25, is mounted on the working part of the second cylinder 66, and the second mounting frame 65 also has suction cups 24 mounted on it. Therefore, when the bag is gripped, since the first mounting frame 25 and the second mounting frame 65 have the same structure—specifically, the number and position of the suction cups 24 on the second mounting frame 65 are the same as those on the first mounting frame 25—the upper bag assembly 2 can transfer the bag located on the second mounting frame 65 to the upper bag assembly 2.

[0033] Furthermore, since the end of the drive shaft 63 away from the second cylinder 66 is also provided with a linkage rod 62, the linkage rod 62 is connected to the eighth cylinder 7 provided on the frame 1, and the drive shaft 63 is rotated through the eighth cylinder 7, thus enabling the rotation of the second mounting bracket 65 to be automatically controlled.

[0034] Furthermore, since the upper end of the support frame 60 is also provided with a limiting plate 64, and a limiting rod 61 is also provided between the support frame 60 and the linkage rod 62, the limiting rod 61 abuts against the limiting plate 64 to prevent the transmission shaft 62 from continuing to rotate. Therefore, the position of the second mounting frame 65 in grasping the bag body can be stable and reliable each time. Preferably, a proximity switch can also be installed on the limiting plate 64. After the proximity switch is triggered by the limiting rod 61, the signal is transmitted to the control device so that the control device can stop the eighth cylinder 7 from working.

[0035] Based on the above solution, since the clamping assembly 3 includes a second bracket 30, the second bracket 30 is provided with a second lead screw 32 and a second lead screw seat 37 adapted and connected to the second lead screw 32, and a support plate 33 is installed on the second lead screw seat 37, and a clamping cylinder 31 is provided at the end of the support plate 33 facing the bag body. Therefore, the second lead screw 32 can be used to drive the support plate 33 to move, so that the distance between the two support plates 33 can be adjusted, thereby enabling the clamping assembly 3 to adapt to bags of different widths.

[0036] Furthermore, since the second bracket 30 is also provided with a guide rail 36 and a slider 38 slidably mounted on the guide rail 36, and the end of the second lead screw seat 37 away from the support plate 33 is fixedly connected to the slider 38, the cooperation between the slider 38 and the guide rail 36 can be used to ensure that the two support plates 33 can slide in a directional manner.

[0037] Furthermore, since the second support 30 is connected to the frame 1 through the connecting frame 34, and the connecting frame 34 is also provided with a third cylinder 35 for causing the second support 30 to slide up or down, when the clamping cylinder 31 clamps the bag body, the third cylinder 35 can be used to raise and lower the second support 30, thereby raising and lowering the bag body.

[0038] Based on the above scheme, the bagging assembly 5 includes a mounting plate 50, with a hopper 53 positioned above the mounting plate 50. A fourth cylinder 51 and a fifth cylinder 54 are also mounted on the bottom surface of the mounting plate 50, and heating plates 55 are installed on the working parts of both the fourth cylinder 51 and the fifth cylinder 54. Therefore, the hopper 53 can be used to receive materials and guide them into the bag. After bagging is completed, the working parts of the fourth cylinder 51 and the fifth cylinder 54 can move towards each other, causing the heating plates 55 to clamp the bag and seal it.

[0039] Furthermore, since the bottom surface of the mounting plate 50 is also provided with a fourth bracket 57 that is sleeved outside the fourth cylinder 51, and the side of the fourth bracket 57 away from the fourth cylinder 51 is also provided with a sixth cylinder 56, and the working part of the sixth cylinder 56 is also equipped with a suction cup 24, when bagging, the clamping cylinder 31 fixes the bag body, the suction cup 24 on the first mounting frame 25 opens the bag body under the action of the first cylinder 23, and the suction cup 24 on the sixth cylinder 56 opens the bag body near the bag opening, so that the bag opening can be opened smoothly during the filling process and the size of the bag opening can be maintained for a long time.

[0040] Furthermore, since the hopper 53 is equipped with a seventh cylinder 52 on both sides, and the hopper 53 is moved upward or downward by the seventh cylinder 52, the bottom of the hopper 53 can be made to go deeper into the bag body by the seventh cylinder 52, so as to reduce the phenomenon of material scattering during bagging.

[0041] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
