[0050] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0051] When the existing packing device takes out the target bag, it is easy to bring out other adjacent bags, and the reliability of the bag-taking operation is relatively low, which is likely to affect the subsequent packing operation.

[0052] To solve the above technical problems, this embodiment provides a bag-taking mechanism. Please refer to Figures 1 to 4 as shown in Figure 1 Figure 1 is the first three-dimensional view of the bag-taking mechanism and the discharging and packing device in the embodiment; Figure 2 Figure 2 is the second three-dimensional view of the bag-taking mechanism and the discharging and packing device in the embodiment; Figure 3 Figure 3 is the top view of the bag-taking mechanism and the discharging and packing device in the embodiment; Figure 4 Figure 4 is the side view of the bag-taking mechanism and the discharging and packing device in the embodiment.

[0053] A bag-taking mechanism 1 in this embodiment includes: a frame 10, a bag bin 11, a roller bracket 12, a vibrating roller 13, and a vibrating mechanism 14.

[0054] The bag bin 11 is arranged on the frame 10. The bag bin 11 is provided with a cavity 111 for accommodating bags and is inclined. There is a clearance opening 112 and a bag outlet 113 at the bottom of the cavity 111. The inclined setting of the cavity 111 means that the bottom of the cavity 111 is inclined so that the bags inside can be in an inclined state. The clearance opening 112 is used to make way for the vibrating roller 13, and the bag outlet 113 is used to output the bag at the bottommost of the cavity 111.

[0055] The roller bracket 12 is connected to the frame 10 through a sliding structure and can be lifted relative to the frame 10 for vibration.

[0056] The vibration roller 13 is arranged on the roller bracket 12. The vibration roller 13 has a self-rotation function and is partially located in the make way port 112 to drive the bag in the cavity 111 to move toward the bag outlet 113. The self-rotation function of the vibration roller 13 can be achieved by driving an existing motor or other driving mechanism, which will not be repeated here.

[0057] The vibration mechanism 14 is disposed on the frame 10 and connected to the roller bracket 12 to drive the vibration roller 13 to vibrate.

[0058] When the bag taking mechanism 1 of the above technical solution is working, the target bag at the bottom of the cavity 111 is driven to move toward the bag outlet 113 by the self-rotation of the vibration roller 13. At the same time, the vibration mechanism 14 drives the vibration roller 13 to vibrate, so that the friction between the target bag and the adjacent bag is reduced due to the vibration. Combined with the inclined design of the cavity 111, the adjacent bag is not easily taken out when the target bag moves. It can be seen that the bag taking mechanism 1 of the above technical solution can effectively reduce the risk of taking out other bags when the target bag is taken out, and has the advantages of high reliability of bag taking operation and convenient use.

[0059] In one embodiment in which the bag bin 11 is disposed on the frame 10 , the bag bin 11 is fixed to the frame 10 by bolt connection, welding or the like.

[0060] In order to facilitate the replacement of bag bins 11 of different types, the bag bins 11 are arranged on the frame 10 in another embodiment, see Figure 1 As shown, the frame 10 is provided with a pair of support frames 101, each of which is provided with a slot 102; a bracket 114 is provided on each of the opposite sides of the bag bin 11, and the two brackets 114 are respectively detachably clamped on the inner sides of the two slots 102 so that the brackets 114 are supported on the support frames 101, so that the bag bin 11 can be quickly installed on the frame 10 through the brackets 114, which is convenient for disassembly and assembly of the bag bin 11.

[0061] In one embodiment of the above roller bracket 12 and the frame 10 being connected via a sliding structure, see Figure 1 and Figure 4 As shown, the roller bracket 12 includes a horizontally extending connecting rod 121 and a vertical rod 122 vertically connected to the middle of the connecting rod 121.

When the vibration mechanism 14 works, the vibration control motor 141 drives the eccentric shaft 142 to rotate, and then drives the connecting rod 121 to move up and down to achieve the vibration function.

[0064] Exemplarily, referring to Figure 1 and Figure 4 As shown in Figure 4 , there are two sets of vibration mechanisms 14, which are respectively disposed at both ends of the connecting rod 121 for synchronously driving the vibrations at both ends of the connecting rod 121.

Both ends of the horizontal moving frame 43 are respectively connected to the two sets of horizontal lead screws 41. At the same time, a guiding structure is formed to limit the rotation of the horizontal moving frame 43 relative to the rotating bracket 31.

[0081] In order to realize automatic feeding before automatic packing and automatic discharging after packing, refer to Figure 1 and Figure 3 As shown, the blanking and packing device further includes a feeding conveyor belt 71 located on one side of the circumferential bracket 2 and a discharging conveyor belt 72 located below the circumferential bracket 2. The feeding conveyor belt 71 is used to convey the materials to be packed, and the discharging conveyor belt 72 is used to output the packed material bags.

[0082] Furthermore, refer to Figure 1 andFigure 3 As shown, the blanking and packing device further includes a pushing mechanism 9 disposed on one side of the feeding conveyor belt 71. The pushing mechanism 9 includes a pushing plate 91 and a pushing driving mechanism 92 that drives the pushing plate 91 to push the materials on the feeding conveyor belt 71 into the bag. The pushing driving mechanism 92 can be an electric push rod or a cylinder fixed on the frame 10, and its driving rod is connected to the pushing plate 91.

[0083] In order to compact the materials after being bagged, refer to Figure 1 、 Figure 3 and Figure 7 As shown, the jaw support 51 is movably disposed on the transverse moving frame 43. The blanking and packing device further includes a bag vibrating mechanism 8. The bag vibrating mechanism 8 includes a rack 81, a bag vibrating gear 82, and a bag vibrating control motor 83. The rack 81 is connected to the transverse moving frame 43 through a sliding structure.

The rack 81 is fixedly connected to the jaw support 51 by bolts or welding and is perpendicular to the transverse lead screw 41 and the bidirectional lead screw 52. The bag vibrating control motor 83 is used to drive the bag vibrating gear 82 to rotate, so as to drive the rack 81 and the jaw support 51 to move relative to the transverse moving seat.

[0084] The working process of the blanking and packing device with the above technical solutions is as follows. When the bag mouth of the bag is output from the bag outlet 113 or the double-layer conveyor belt 15, as Figure 5 shown, the air blowing mechanism 6 blows air into the bag output from the bag outlet 113 to open the bag; subsequently, the bag grasping mechanism 5 uses the bag opening control motor 53 to drive the bidirectional lead screw 52 to rotate, so as to drive the two electric jaws 55 to move in opposite directions, making the electric jaws 55 face the preset bag grasping position, moving towards the bag mouth direction through the circumferential bracket 2, so that the upper and lower electric jaws 55 can respectively grasp the upper and lower surfaces of the bag mouth, and then the electric jaws 55 move away from each other, thus opening the bag mouth; then, as Figure 6 shown, the rotating mechanism 3 drives the rotating gear 33 to rotate through the rotation control motor 32, and then drives the rotating bracket 31 to rotate around the circumferential bracket 2 to make the bag mouth face upward for convenient loading; subsequently, the transverse moving mechanism 4 drives the transverse lead screw 41 to rotate through the transverse control motor 42, driving the transverse moving frame 43 to move along the extending direction of the transverse lead screw 41 to make the bag mouth close to the feeding conveyor belt 71; then, the pushing mechanism 9 pushes the materials into the bag through the pushing plate 91; subsequently, as Figure 7 shown, the transverse moving mechanism 4 drives the bag to move above the blanking conveyor belt 72. The bag vibrating mechanism 8 drives the bag vibrating gear 82 to rotate through the bag vibrating control motor 83, so as to drive the rack 81 and the jaw support 51 to move up and down relative to the transverse moving seat, making the bag repeatedly fall on the blanking conveyor belt 72 and then lift, making the materials more compact; finally, the electric jaws 55 release the bag, and the bag falls onto the blanking conveyor belt 72 and is output through the blanking conveyor belt 72.

[0085] It can be seen that the blanking and packing device of the above technical solution realizes the four-step integrated operation of bag taking, bag opening, loading, and feeding in a limited space, greatly saving the labor cost of the assembly line operation, improving the production efficiency, and reducing the equipment occupation space. Among them, the blanking and packing device can freely adjust the distance between the electric grippers 55 to automatically adapt to the bag mouth position and accurately grab the bag; the blanking and packing device can also move the bag close to the blanking conveyor belt 72 to reduce material scattering; the blanking and packing device can also compact the materials in the bag through the bag vibrating mechanism 8 to eliminate the uneven loading that may occur during loading.
