Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0028] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Example 1

[0030] The following reference Figure 1-Figure 7 As shown, combined with a specific embodiment to further illustrate, the utility model is an automatic bag placing machine, referring to Figure 1 , Figure 2As shown, it includes a frame 1, multiple groups of conveying components 4, multiple groups of swinging members 6, a driving component 5 and a transition conveyor 7. The frame 1 is arranged outside the cooling tunnel 2 and above the conveying chain plate 3; the multiple groups of conveying components 4 are evenly distributed along the length direction of the frame 1; the driving component 5 is arranged on the frame 1 and can drive the multiple groups of conveying components 4 to transmit simultaneously to convey the materials; the multiple groups of swinging members 6 correspond to the multiple groups of conveying components 4 one by one and can drive the conveying components 4 to swing so that the materials fall onto the conveying chain plate 3; the transition conveyor 7 is arranged outside the frame 1 and can convey the materials to the conveying component 4 located at the end of the frame 1. The transition conveyor 7 conveys the packaged bag containing the hot pot base to the conveying component 4 located at the end, and then the multiple groups of conveying components 4 convey the package bag in turn. When the package bag is transported to the designated position and needs to fall to the conveying chain plate 3, the conveying component 4 is driven to flip by the swinging member 6, that is, the package bag can fall to the corresponding position of the conveying chain plate 3. Since the packaging bags directly rely on the conveying assembly 4 rather than the thrust of the next packaging bag during the conveying process, there will be no stacking between adjacent packaging bags, so the packaging bags are not likely to overlap when falling onto the conveying chain plate 3.

[0031] Reference Figure 3 , Figure 4 As shown, the conveying assembly 4 includes a first support plate 41 and a second support plate 42, a driving roller 43 and a driven roller 44 are arranged between the first support plate 41 and the second support plate 42, and a plurality of transmission ropes 45 are arranged between the driving roller 43 and the driven roller 44. Each driving roller 43 extends outside the frame 1, and a linkage wheel 431 is arranged at one end of the driving roller 43 outside the frame 1, and a synchronous belt 432 is wound between the plurality of linkage wheels 431. The driving assembly 5 includes a driving motor 51, a main pulley 52, a slave pulley 53 and a transmission belt 54. The driving motor 51 is fixedly arranged on the frame 1, the main pulley 52 is coaxially connected to the output shaft of the driving motor 51, the slave pulley 53 is coaxially connected to one of the driving rollers 43, and the transmission belt 54 is wound between the main pulley 52 and the slave pulley 53. Start the drive motor 51, and the output shaft of the drive motor 51 drives the main pulley 52 to rotate. The main pulley 52 drives the slave pulley 53 to rotate synchronously through the transmission belt 54, so that one of the active rollers 43 drives the interlocking wheel 431 connected to the active roller 43 to rotate, and the rotating interlocking wheel 431 drives all the interlocking wheels 431 to rotate through the synchronous belt 432, thereby causing all the active rollers 43 to rotate. When the active roller 43 rotates, multiple transmission ropes 45 drive the driven rollers 44 to rotate synchronously, so that the transmission ropes 45 can transport the packaging bags.

[0032] Reference Figure 4As shown, the swing member 6 includes an upper support block 61, a downward pressure cylinder 62, a downward pressure shaft 63 and a lower support block 64. The upper support block 61 is fixedly mounted on the frame 1. The cylinder barrel of the downward pressure cylinder 62 is rotatably connected to the upper support block 61. The downward pressure shaft 63 is fixedly connected to the piston rod of the downward pressure cylinder 62. The bottom end of the downward pressure shaft 63 is provided with a collar 631. The lower support block 64 is fixedly arranged on the first support plate 41 and rotatably cooperates with the collar 631. One end of the first support plate 41 is rotatably connected to the frame 1, so that when the lower support block 64 is subjected to a downward thrust, the first support plate 41 can be turned downward as a whole. Starting the downward pressure cylinder 62 and moving the piston rod of the downward pressure cylinder 62 out of the cylinder barrel can drive the downward pressure shaft 63 to apply a thrust to the lower support block 64, so that the lower support block 64 drives the conveying assembly 4 to turn over as a whole through the first support plate 41, so that the packaging bag can fall obliquely downward onto the conveying chain plate 3.

[0033] Reference Figure 1 , Figure 2 As shown, a lifting mechanism 13 is also provided at the bottom of the frame 1, and the lifting mechanism 13 includes a plurality of lifting cylinders 131, and the plurality of lifting cylinders 131 are respectively located at the four corners of the bottom of the frame 1, and the cylinder barrels of the lifting cylinders 131 are fixedly mounted on the brackets of the conveying chain plate 3, and the piston rods of the lifting cylinders 131 are fixedly connected to the bottom of the frame 1. When there is no need to swing the bag, for example, when cooling the boxed hot pot soup base, there is no need to use a bag swinging machine, but directly transport it from the other end of the conveying chain plate 3 to the cooling tunnel 2. At this time, the lifting cylinders 131 are started and the piston rods of the lifting cylinders 131 are extended outward, that is, the frame 1 can be driven to move upward as a whole, so that there is a large height difference between the frame 1 and the conveying chain plate 3, so as to avoid obstruction to the boxed hot pot soup base transported on the conveying chain plate 3.

[0034] Reference Figure 2 , Figure 5 As shown, an auxiliary shaft 71 is installed at one end of the infeed conveyor 7 close to the frame 1, and a plurality of auxiliary ropes 72 are arranged between the auxiliary shaft 71 and the active roller 43 close to the infeed conveyor 7. When the active roller 43 close to the infeed conveyor 7 rotates, the auxiliary shaft 71 can be driven to rotate through the auxiliary rope 72. When the infeed conveyor 7 conveys the packaging bag to the end, the auxiliary rope 72 can continue to drive the packaging bag to move forward to the conveying assembly 4 adjacent to the infeed conveyor 7, thereby ensuring the continuity of the conveying process.

[0035] Reference Figure 2 , Figure 6As shown, a guide assembly 8 is provided on the frame 1 and below the conveying assembly 4. The guide assembly 8 includes mounting beams 81 provided on both sides of the frame 1. A plurality of guide plates 82 are distributed between the two mounting beams 81 along the length direction of the frame 1. The plurality of guide plates 82 correspond to the plurality of conveying assemblies 4 one by one. Each guide plate 82 is tilted and located at one side of the bottom of the conveying assembly 4. When the packaging bag falls from the conveying assembly 4, the guide plate 82 can guide the packaging bag, thereby ensuring the accuracy of the position of the packaging bag when it falls to the conveying chain plate 3, and is not prone to large deviation.

[0036] Reference Figure 6 , Figure 7 As shown, the frame 1 is provided with a plurality of support plates 9 for supporting the mounting beam 81, the support plate 9 is provided with a first adjusting screw 91, the first adjusting screw 91 is threadedly connected with a first adjusting nut 92, and the mounting beam 81 is provided with a first strip groove 811 along its length direction for the first adjusting screw 91 to move. The frame 1 is provided with a second adjusting screw 11, the second adjusting screw 11 is threadedly connected with a second adjusting nut 12, and the support plate 9 is provided with a second strip groove 93 along the vertical direction for the second adjusting screw 11 to move. By adjusting the position of the mounting beam 81 along the length direction of the frame 1, and after the adjustment is completed, by tightening the first adjusting nut 92 and making the first adjusting nut 92 abut against the mounting beam 81, the position of the guide assembly 8 in the length direction of the frame 1 can be adjusted; by adjusting the position of the support plate 9 along the vertical direction, and after the adjustment is completed, by tightening the second adjusting nut 12 and making the second adjusting nut 12 abut against the support plate 9, the position of the guide assembly 8 in the vertical direction can be adjusted. The positions of the guide assembly 8 in both the vertical and horizontal directions can be adjusted, so it can be suitable for packaging bags of different specifications.
