It should be understood that the specific embodiments described herein are only used to explain the utility model, and are not used to limit the utility model.

[0027] As Figures 1-8 shown is a bag feeding device of a packaging machine, comprising a driving module, a bag taking module 4 and a bag moving module 5, the driving module comprises a power source 6 and a power distribution mechanism, the power source 6 divides a first power output and a second power output through the power distribution mechanism, the first power output drives the bag taking module 4 to act, so as to convey the packaging bag from the storage position to the handover position, the second power output drives the bag moving module 5 to act, so as to receive the packaging bag in the handover position and convey it to the bag feeding position. In the embodiment, the bag taking module 4 and the bag moving module 5 share one power source 6, which not only reduces the cost of the equipment, but also reduces the volume of the equipment, and does not need to design a complex independent transmission system for the bag taking module 4 and the bag moving module 5, so that the whole mechanical transmission system is more simple, easy to maintain and manage.

[0028] In the embodiment, the power distribution mechanism comprises a power shaft I in transmission connection with the power source 6, the power shaft I constitutes the first power output, and the power shaft I is provided with an output member to constitute the second power output. The power shaft I drives the bag taking module 4 to act to transport the packaging bag from the storage position to the handover position. The output member 2 can be a belt wheel, a chain wheel or a gear wheel alone or in combination to constitute, and the second power output drives the bag moving module 5 to act to receive the packaging bag at the handover position and transport it to the upper bag position. Preferably, the output member 2 is a bevel gear I, the bevel gear I is in meshing with a bevel gear II and the rotation axes are perpendicular to each other, so that the power source 6 distributes the first power output and the second power output which are perpendicular to each other through the power distribution mechanism.

[0029] In the embodiment, the bag taking module 4 comprises a cam member 401 and a bag taking assembly, the cam member 401 is driven to rotate by the first power output, and the bag taking assembly is driven to reciprocate between the storage position and the handover position by the cam member 401. The cam member 401 can drive the bag taking assembly to reciprocate in swing motion or reciprocate in straight line motion between the storage position and the handover position. Preferably, the bag bin at the storage position is obliquely arranged to avoid the problem that the lower packaging bag is excessively pressed due to the conventional vertical stacking of the packaging bags, and to reduce the possibility of adhesion of the packaging bags. The cam member 401 drives the bag taking assembly to reciprocate in swing motion between the storage position and the handover position, which facilitates the bag taking assembly to fit and catch the packaging bag at the bottom of the obliquely arranged bag bin 3.

[0030] Preferably, the bag taking assembly is arranged on a swing arm 402 in swing arrangement, and the cam member 401 drives the swing arm 402 to swing to make the bag taking assembly reciprocate between the storage position and the handover position. This mechanical transmission mode is stable and reliable, and the bag taking assembly is connected to the swing arm 402, which can quickly and accurately reach the position corresponding to the bag bin 3 to perform the bag taking operation with the swing of the swing arm 402.

[0031] In the embodiment, the driving track of the cam member 401 comprises a first driving section and a second driving section. The first driving section has a constant radius to the rotation axis of the cam member 401, so as to maintain the bag taking assembly at the handover position when the cam member 401 rotates. The second driving section has a variable radius to the rotation axis of the cam member 401, so as to drive the bag taking assembly to reciprocate between the storage position and the handover position when the cam member 401 rotates. Preferably, the first driving section and the second driving section are a first profile and a second profile of the outer circumferential surface of the cam member 401.

The second profile has a constant radius to the rotation axis of the cam member 401, so as to maintain the bag taking assembly at the handover position when the cam member 401 rotates. After the bag taking assembly receives the packaging bag from the storage position and moves to the handover position, the bag taking assembly is in a stationary state, which provides a stable time window for the bag moving module 5 to receive the packaging bag from the bag taking module 4, and improves the coordination and stability of the whole bag feeding device. In other possible embodiments, the first driving section and the second driving section can also be guide grooves.

[0032] In the embodiment, the bag moving module 5 comprises a linear moving mechanism and a bag moving assembly.

The seat body is connected with the linear moving mechanism to reciprocate between the handover position and the bag feeding position. The first holding part 501 and the second holding part 502 are respectively provided with suction cups. The first holding part 501 and the second holding part 502 are respectively connected with the seat body in a sliding manner. The sliding direction of the first holding part 501 and the second holding part 502 forms an angle with the moving direction of the linear moving mechanism, so that the first holding part 501 and the second holding part 502 can move close to or away from each other during the movement. The linear moving mechanism is provided with guide rails 504 beside the moving path of the linear moving mechanism. The guide rails 504 are configured to drive the first holding part 501 and the second holding part 502 to close to clamp the packaging bag to receive the packaging bag when the bag moving assembly moves to the handover position, and drive the first holding part 501 and the second holding part 502 to separate to open the bag opening of the packaging bag when the bag moving assembly moves to the bag feeding position. As shown in FIG. 6, the bag moving assembly is provided with a first guide rail 504a and a second guide rail 504b. The first guide rail 504a is configured to drive the first holding part 501 to move close to the second holding part 502 to clamp the packaging bag to receive the packaging bag when the bag moving assembly moves to the handover position. The second guide rail 504b is configured to drive the second holding part 502 to move close to the first holding part 501 to clamp the packaging bag to receive the packaging bag when the bag moving assembly moves to the handover position. Figures 7-8As shown, the first holding part 501 and the second holding part 502 are connected to the guide rail 504 which gradually approaches each other near the transfer position. In other possible embodiments, the guide rail 504 can also gradually move away from each other near the transfer position.
