[0040] For better explaining the present utility model for easy understanding, the present utility model will be described in detail below with reference to the accompanying drawings through specific implementation manners.

[0041] Please refer to Figures 1 to 3 , the present utility model provides a bag taking mechanism for packaging bags, including a conveyor belt 1, a material transfer mechanism 2, a bag sucking mechanism 3 and a bag supply mechanism 4;

[0042] The bag sucking mechanism 3 is arranged on one side of the starting end of the conveyor belt 1;

[0043] The bag supply mechanism 4 is arranged directly below the bag sucking mechanism 3. The bag supply mechanism 4 includes a frame 48, a feeding rack 41, a clamping plate 42, a guide rod 43, a guide cylinder 44, a connecting plate 45, a pulley 46, a traction rope and a counterweight 47;

[0044] The feeding rack 41 is arranged on the frame 48. The cross-section of the feeding rack 41 is in a U-shaped structure, and a limiting plate is arranged at the top of the feeding rack 41;

[0045] The clamping plate 42 is arranged in the feeding rack 41, and the packaging bag is clamped between the limiting plate and the clamping plate 42;

[0046] The guide rod 43 is vertically arranged at the bottom of the clamping plate 42;

[0047] The guide cylinder 44 is mounted on the frame 48 and sleeved on the guide rod 43;

[0048] The connecting plate 45 fixing plate is installed at the bottom of the guide rod 43;

[0049] The pulley 46 is mounted in the frame 48;

[0050] One end of the traction rope is fixedly connected to the connecting plate 45, and the other end of the traction rope is connected to the counterweight 47 after being pulled by the pulley 46;

[0051] The material transfer mechanism 2 is arranged at the starting end of the conveyor belt 1, and is used to move the packaging bags sucked up by the bag suction mechanism 3 to the conveyor belt 1;

[0052] When in use, the stacked packaging bags are placed between the limit plate and the clamping plate 42. Under the action of the counterweight block 47, the traction rope pulls the connecting plate 45 upward through the pulley 46, and then the packaging bags are firmly clamped between the limit plate and the clamping plate 42. The lifting cylinder 31 drives the bag suction seat 32 to move downward, so that the gap between the limit plate and the clamping plate 42 is increased. During the resetting process of the lifting cylinder 31, the bag suction seat 32 sucks up the packaging bags at the top, and cooperates with the material transfer mechanism 2 to move the sucked packaging bags to the conveyor belt 1, so as to realize the automatic loading of packaging bags one by one.

[0053] refer to Figure 5 In this embodiment, the bag suction mechanism 3 includes a lifting cylinder 31 and a bag suction seat 32. The lifting end of the lifting cylinder 31 is connected to the bag suction seat 32, and a plurality of negative pressure air holes are arranged at the bottom of the bag suction seat 32. The lifting cylinder 31 controls the lifting and lowering movement of the bag suction seat 32. When the bag suction seat 32 moves downward, the gap between the limit plate and the clamping plate 42 increases. During the resetting process of the lifting cylinder 31, the bag suction seat 32 sucks up the packaging bag at the top.

[0054] In this embodiment, the material moving mechanism 2 includes a transverse moving component 21 and a material moving seat 22. The material moving seat 22 is connected to the moving end of the transverse moving component 21, and a plurality of negative pressure air holes are provided at the bottom of the material moving seat 22. A material moving groove corresponding to the material moving seat 22 is provided on the bag suction seat 32. After the transverse moving component 21 moves the material moving seat 22 to the material moving groove on the bag suction seat 32, the packaging bag is sucked up through the negative pressure air holes at the bottom of the material moving seat 22, and then cooperates with the transverse moving component 21 to return to the conveyor belt 1, thereby realizing the movement of the packaging bag.

[0055] In this embodiment, the lateral moving component 21 includes a rotating wheel, a moving belt and a motor. There are two rotating wheels, which are symmetrically arranged on the left and right. The moving belt is installed between the two rotating wheels. The material transfer seat 22 is fixed on the moving belt, and the motor is connected to one of the rotating wheels.

[0056] refer to Figure 4In this embodiment, two groups of bag supply mechanisms 4 are provided, and the two groups of bag supply mechanisms 4 are arranged side by side and connected to a switching mechanism 5. The switching mechanism 5 realizes the movement and switching of the two groups of bag supply mechanisms 4 under the bag suction mechanism 3. The switching mechanism 5 includes a slide rail 51, a slider 52 and a pneumatic cylinder 53. The slide rail 51 is arranged on the frame 48, and the slider 52 is slidably installed on the slide rail 51. The top of the slider 52 is connected to the bag supply mechanism 4, and the piston rod of the pneumatic cylinder 53 is connected to the slider 52;

[0057] When in use, the slider 52 is driven to move by the pneumatic cylinder 53, so that the two groups of bag supply mechanisms 4 can be moved and switched below the bag suction mechanism 3, thereby improving the bag taking efficiency.

[0058] The working principle of the utility model is as follows:

[0059] The stacked packaging bags are placed between the limit plate and the clamping plate 42. Under the action of the counterweight 47, the traction rope pulls the connecting plate 45 upward through the pulley 46, and then the packaging bags are firmly clamped between the limit plate and the clamping plate 42. The lifting cylinder 31 drives the bag suction seat 32 to move downward, so that the gap between the limit plate and the clamping plate 42 is increased. During the resetting process of the lifting cylinder 31, the bag suction seat 32 sucks up the packaging bags at the top, and cooperates with the material transfer mechanism 2 to move the sucked packaging bags to the conveyor belt 1, so as to realize the automatic loading of packaging bags one by one.
