[0023] The present invention will be further described below in conjunction with specific embodiments. The purpose is only to provide a better understanding of the content of the present invention. Therefore, the examples given do not limit the scope of protection of the present invention.

[0024] like Figures 1 to 5 As shown, this embodiment provides a bag shooting mechanism, including a mounting frame 1, which is rectangular when viewed from above. A bag shooting device and a bag clamping device are provided at the bottom of the mounting frame 1. A power unit 1 is provided corresponding to the bag clamping device, and the power unit 1 controls the bag clamping device to achieve a clamping action; a power unit 2 is provided corresponding to the bag shooting device, and the power unit 2 drives the bag shooting device to shoot the packaging bag onto the feeding tube.

[0025] A plurality of connecting pipes 3 are provided at intervals on the right side of the bottom of the mounting frame 1, and the lower end of the connecting pipe 3 is connected to a second mounting plate 4 of full length; the bag shooting device includes a long fixed wheel group and an adjusting wheel group; the long fixed wheel group is installed on the second mounting plate 4, including a driving pulley 5 and a passive pulley 6, and a plurality of supporting pulleys 13 are provided at intervals between the driving pulley 5 and the passive pulley 6; a multi-V belt 7 is installed on the driving pulley 5 and the passive pulley 6; the power unit 2 is arranged at the front end of the second mounting plate 4 and is connected to the driving pulley 5 for transmission; an adjusting connecting frame is provided at the front left side of the bottom of the mounting frame 1, and the lower end of the adjusting connecting frame is connected to a third mounting plate 29, and the adjusting wheel group includes a plurality of bag clamping wheels 14 installed at intervals on the third mounting plate 29. The inner side of the multi-V belt 7 is attached with a plurality of transverse triangular wedges 701, and the outer side of the multi-V belt 7 is provided with a rubber layer, on which a plurality of longitudinal grooves 702 are spaced apart. This increases the friction between the multi-V belt 7 and the packaging bag. Under the action of the bag clamping device, the increased friction between the multi-V belt 7 and the packaging bag can further prevent the packaging bag from falling. The driving pulley 5, the driven pulley 6, and the supporting pulley 13 are all multi-V belt pulleys adapted for the multi-V belt 7. The longitudinal grooves 702 increase the friction between the multi-V belt 7, the packaging bag, and the bag clamping wheel 14 and the bag clamping wheel 2, preventing the packaging bag from falling during the bag ejection process. The transverse triangular wedges 701 ensure the friction between the multi-V belt 7 and the driving pulley 5, the driven pulley 6, and the supporting pulley 13. When the driving pulley 5 rotates, it can drive the multi-V belt 7 to move, and then drive the driven pulley 6 and the supporting pulley 13 to rotate synchronously, thereby ensuring that the packaging bag is quickly and stably ejected to the filling port.

[0026] Power unit 2 includes a second power unit bracket 24 connected to the second mounting plate, and a second drive motor 8 is provided on the second power unit bracket 24. The output shaft of the second drive motor 8 is vertically arranged, and a toothed pulley 1 9 is provided on the output shaft of the second drive motor 8. A toothed pulley 2 10 is provided on the rotating shaft of the driving pulley 5. The toothed pulley 1 9 and the toothed pulley 2 10 are connected by a synchronous toothed belt 11.

[0027] The bag clamping device includes a swing arm 2 and a clamping wheel group; the swing arm 2 is rotatably connected to the rear left side of the bottom of the mounting frame 1 through the swing arm rotating shaft 28, the power unit 1 is directly connected to the upper swing arm rotating shaft 28 of the swing arm 2, and a first mounting plate 12 is provided at the lower end of the swing arm 2. The clamping wheel group includes several bag clamping wheels 22 installed on the first mounting plate 12. The clamping wheel group cooperates with the long fixed wheel group and the multi-V belt 7 to achieve clamping of the packaging bag.

[0028] The power unit 1 includes a first power unit bracket 18 arranged at the bottom of the mounting frame 1, and the first drive motor 15 is arranged on the first power unit bracket 18, and the output shaft of the first drive motor 15 is arranged horizontally; the first power unit bracket 18 is also provided with a swing arm connecting bearing seat 19, and the swing arm rotating shaft 28 is installed on the swing arm connecting bearing seat 19, and the swing arm rotating shaft 28 is coaxially arranged with the output shaft of the first drive motor 15 and connected through a coupling.

[0029] A plug-in plate 30 is provided at the lower end of the swing arm 2, and a group of L-shaped guide rails 31 are provided on the first mounting plate 12 corresponding to the plug-in plate 30. The plug-in plate 30 is slidably inserted into the corresponding L-shaped guide rail group 31; a connecting bolt 32 is also provided between the plug-in plate 30 at the lower end of the swing arm 2 and the first mounting plate 12.

[0030] Before the bag shooting mechanism is operated, professionals are required to adjust the position of the first mounting plate 12. By adjusting the connecting bolts 32, the distance between the first mounting plate 12 and the second mounting plate 4 is adjusted, and then the gap between the bag clamping wheel 22 and the multi-V belt 7 is adjusted until the bag clamping device can clamp the packaging bag and ensure that the packaging bag is smoothly shot out.

[0031] The adjustment connecting frame consists of a fixed bracket 20 and a swivel bracket 26; the fixed bracket 20 is located on the front side of the mounting frame 1, and the swivel bracket 26 is located on the lower side of the mounting frame 1. A hinge shaft 27 is provided at the upper and middle parts of the swivel bracket 26. The swivel bracket 26 is hinged to the mounting frame 1 through the upper hinge shaft 27. The fixed bracket 20 is connected to the middle hinge shaft 27 of the swivel bracket 26 through an adjusting bolt 21 and is fixed by a nut.

[0032] Before the bag shooting mechanism is operated, a professional is required to adjust the position of the swivel bracket 26. By adjusting and screwing the adjusting bolt 21, the angle between the swivel bracket 26 and the horizontal plane can be adjusted, thereby adjusting the gap between the bag clamping wheel 14 and the multi-V belt 7 and the supporting pulley 13 inside the multi-V belt 7 to avoid the gap being too large, causing the packaging bag to fall when it is transferred to the space between the front bag clamping wheel 14 and the multi-V belt 7, or the gap being too small, causing the packaging bag to get stuck and unable to be shot out.

[0033] It also includes a bag opening retaining frame, which includes a first bent plate 16, a second bent plate 17 and a third bent plate 23 with a V-shaped side cross-section. The first bent plate 16, the second bent plate 17 and the third bent plate 23 form a conveying trough with a diamond-shaped side cross-section, which is used to accommodate the bag opening of the packaging bag; the first bent plate 16 is connected to the first mounting plate 12 through the combined connecting frame 25, the second bent plate 17 is connected to the second mounting plate 4 through the combined connecting frame 25, and the third bent plate 23 is connected to the third mounting plate 29 through the combined connecting frame 25.

[0034] The operation process of this mechanism is as follows: when the output end of the first drive motor 15 rotates clockwise, it drives the swing arm rotating shaft 28 to rotate, and then drives the swing arm 2 to rotate outward and open. Then, the suction belt mechanism in the prior art is used to lift the packaging bag to between the second bag clamping wheel 22 and the multi-V belt 7. When the bag opening of the packaging bag rises to the position of the bag opening retaining frame, the output end of the second drive motor 8 rotates counterclockwise, driving the swing arm 2 to rotate inward until the second bag clamping wheel 22 and the multi-V belt 7 and the supporting pulley 13 inside the multi-V belt 7 work together to clamp the packaging bag. At the same time, the bag opening of the packaging bag is accommodated in the conveying groove of the bag opening retaining frame; then The first drive motor 15 stops, the suction belt mechanism lowers the bag, and the output shaft of the second drive motor 8 drives toothed pulley 1 9. Toothed pulley 1 9 drives toothed pulley 2 10 via a synchronous toothed belt 11. Toothed pulley 2 10 drives the coaxial driving pulley 5, which in turn drives the driven pulley 6 via a poly-V belt 7. As the poly-V belt 7 rotates, the bag is clamped between the poly-V belt 7 and the bag clamping wheel 2 22, and between the poly-V belt 7 and the bag clamping wheel 1 14. Friction drives the bag forward rapidly, allowing the bag opening to be inserted into the filling port of the rotary packaging machine. Compared to the manual bagging method in the prior art, the bag ejection mechanism meets the needs of modern production and is more efficient. It not only reduces worker labor intensity but also prevents dust from harming worker health.

[0035] like Figure 5 , this application is used in conjunction with the bag suction mechanism in the prior art, including a front bag suction part and a rear bag suction part. The suction belt mechanism in the prior art can refer to the swing-arm type bottom-paste bag inserting machine with application number CN202121363311.6. The bag suction mechanism includes: a front bag suction part and a rear bag suction part; the front bag suction part includes: a bracket base, a left and right adjustment seat, a front and rear adjustment seat, a rotating shaft support, a front bag suction drive motor, a front bag suction adjustment rod, a bracket arm, a bag suction rod and a front suction cup; the rear bag suction part includes: a rear bag suction support, a rear bag suction cylinder, a suction cup bracket and a rear suction cup; when the swing arm is swung to a certain angle, the front bag suction drive motor drives the bracket arm to swing downward through the rotating shaft support, and the bag suction rod and the bag suction rod on it The front suction cup swings downward together with the bracket arm, and the length of the front bag suction adjustment rod is adjusted to ensure that the front suction cup on the bag suction rod always remains in the downward direction during the movement until the front suction cup presses the front part of the packaging bag to be sucked and sucks the packaging bag, and then the front bag suction part moves back to the initial position with the grabbed packaging bag, waiting for the bag clamping device to clamp it; when the front bag suction part starts to suck the bag, the rear bag suction cylinder drives the suction cup bracket to descend, so that the rear suction cup presses the rear part of the packaging bag to be grabbed, and the suction cup sucks the packaging bag at the same time; after the front bag suction mechanism sucks up the packaging bag and the bag clamping device clamps the packaging bag, the rear bag suction cylinder drives the suction cup bracket to rise, and drives the rear suction cup back to the waiting position together.
