During the secondary poking operation, the seventh cylinder 4-1 pushes the bag tightening poking rod 4-2 to perform secondary poking.

[0041] like Figure 7~Figure 8As shown, the bag feeding device 5 includes a support frame and a bag clamping mechanism 5-1 and a bag pulling mechanism 5-2 fixed on the support frame. The bag pulling mechanism is located below the bag clamping mechanism. The bag pulling mechanism can clamp or release the packaging bag. The bag clamping mechanism can clamp or release the packaging bag relative to the bag pulling mechanism. The bag pulling mechanism can reciprocate back and forth relative to the bag clamping mechanism in a direction perpendicular to the clamping direction to convey the packaging bag. Specifically, the bag clamping mechanism includes a first sliding seat 5-11, a second sliding seat 5-12, a first slide rail 5-13, a third driving device 5-14, a first clamping rod 5-15 arranged on the first sliding seat 5-11, and a second clamping rod 5-16 arranged on the second sliding seat 5-12. The first clamping rod and the second clamping rod are arranged opposite to each other. The third driving device drives the first sliding seat and / or the second sliding seat to reciprocate along the first slide rail so that the first clamping rod and the second clamping rod clamp or release the packaging bag. The bag clamping mechanism is equipped with a reducer by the third driving device 5-14 and connected to the transmission shaft 5-3. The transmission shaft 5-3 is fixed by a bearing seat 5-4, and the two ends are connected to a swing arm 5-5. The swing arm 5-5 is connected by a plurality of long and short connecting rods 5-6. The long and short connecting rods are respectively connected to the first sliding seat 5-11 and the second sliding seat 5-12. The first sliding seat 5-11 and the second sliding seat 5-12 are guided to slide by the first slide rail 5-13. The first clamping rod 5-15 and the second clamping rod 5-16 are fixed on the sliding seat. The movement principle is that the transmission shaft 5-3 is driven by the third driving device 5-14, and the two ends of the transmission shaft 5-3 are connected to connecting rods 5-6, and the connecting rods 5-6 connect the left and right sliding seats to realize the opening and closing movement. The bag pulling mechanism 5-2 includes a third sliding seat 5-21, a fourth sliding seat 5-22, a second slide rail 5-23, a third slide rail 5-24, a fourth driving device 5-25, a fifth driving device 5-26, a third clamping rod 5-27 arranged on the third sliding seat, and a fourth clamping rod 5-28 arranged on the fourth sliding seat. The third clamping rod and the fourth clamping rod are arranged opposite to each other.

The fifth driving device drives the bag pulling mechanism to reciprocate back and forth along the third slide rail relative to the bag clamping mechanism. The bag pulling part is driven by the fourth driving device 5-25 connected to the reducer and connected to the transmission shaft 5-31. The transmission shaft 5-31 is fixed by a bearing seat 5-32, and the two ends are connected to the bag delivery swing arm 5-33. The bag delivery swing arm 5-33 is connected by a plurality of long and short connecting rods 5-34. The long and short connecting rods are connected to the third sliding seat 5-21 and the fourth sliding seat 5-22 respectively. The third clamping rod 5-27 and the fourth clamping rod 5-28 are fixed on the sliding seat. The fifth driving device 5-26 is connected to the third slide rail 5-24. The nut and the linear guide rail 5-35 of the third slide rail 5-24 are fixed on the fixed plate 5-36. The fixed plate 5-36 is connected to the sliding seat through the connecting rod 5-34.The movement principle is that the fourth drive device 5-25 drives the transmission shaft to rotate forward and reverse, driving the swing arm to rotate back and forth. The swing arm drives the connecting rod to transmit the reciprocating motion to the third clamping rod 5-27 and the fourth clamping rod 5-28 through the third sliding seat 5-21 and the fourth sliding seat 5-22, so as to realize the reciprocating opening and closing motion of the clamping rod and realize the clamping and releasing functions. The fifth drive device 5-26 drives the ball screw 5-34 to reciprocate linearly in forward and reverse rotation. The motion is transmitted to the sliding seat through the fixed plate. The sliding seat is realized to reciprocate left and right as a whole. The third, fourth and fifth drive devices can be optionally servo motors.

[0042] The bag feeding device of the present application adopts a method of clamping and fixing the packaging bag to replace the cam feeding method of the horizontal bag feeding packaging machine. When in use, the bag pulling mechanism receives and clamps the packaging bag, and then moves toward the bag clamping mechanism. After the bag pulling mechanism moves a certain distance, the bag clamping mechanism clamps the packaging bag from above the bag pulling mechanism. After the bag clamping mechanism clamps the packaging bag, the bag pulling mechanism retreats to the initial position and re-receives a new bag. At the same time, the bag pulling mechanism clamps the packaging bag clamped by the clamping mechanism again, driving the clamped packaging bag to move forward, and this cycle is repeated, thereby completing the purpose of automatic conveying of the packaging bag. The bag feeding device in the present application has a relatively simple structure, low cost, stable operation, and convenient debugging and maintenance.

[0043] In a specific embodiment, Figure 4 As shown, the bag suction device 2 also includes a liftable insert device including two inserts, which can be inserted into the packaging bag. Specifically, the insert 2-12 can be connected to the fourth cylinder 2-8 and the fifth cylinder 2-9 respectively. In the process of the suction device sucking and initially separating the packaging bag, the insert 2-12 is controlled by the cylinder device to descend and extend from the separation gap to the packaging bag. The insert device is connected to the sliding device as a whole. Therefore, like the suction device, the first driving device can drive the sliding device to make the two inserts move back and forth relative to each other within a certain distance in the horizontal direction, thereby realizing the separation of the bag mouth of the packaging bag. The arrangement of this embodiment is mainly for the case where there is a self-sealing zipper or the bag mouth is not easy to separate, and the purpose of bag mouth separation cannot be achieved by the suction cup alone. The structure of the suction cup and the insert is used to jointly realize the action of sucking the bag, improve the success rate of bag mouth separation, and is also conducive to the completion of subsequent actions. At the same time, this solution overcomes the problem that the suction cup sometimes affects the efficiency of pulling the bag due to air pressure.

[0044] In a specific embodiment, Figure 4As shown, blocks 2-7 are also provided at the suction cups 2-6 on both sides of the packaging bag on the sliding device. The blocks 2-7 are provided on the mounting section of the slider 2-11 and are located between the suction cups 2-6 on the same side. After the suction cups 2-6 absorb the packaging bag, the packaging bag is close to the blocks 2-7. The function of the blocks 2-7 is to limit the packaging bag from both sides. Further, when there is an inserting device, the blocks 2-7 protrude from the suction cups 2-6 and do not exceed the vertical surface of the nearest insert, which facilitates the insertion of the inserting device. Further, the two inserting pieces of the inserting device are provided with a foldable sheet-shaped inserting portion, and the inserting top of the inserting portion is an inverted cone-shaped tip. The insertion sections of the two inserting pieces are completely close to each other, and the top of the insertion section is processed into an inverted cone, which is conducive to insertion and further improves the success rate of bag opening separation.

[0045] Furthermore, each clamping rod comprises a plurality of sub-rod pairs arranged at intervals, wherein the sub-rod pairs comprise a first sub-rod and a second sub-rod, and the first sub-rod and the second sub-rod are arranged at intervals. As shown in the figure, the plurality of sub-rod pairs are arranged at intervals to facilitate the reciprocating motion of the bag pulling mechanism. The first sub-rod and the second sub-rod are arranged at intervals to leave a certain space to facilitate the clamping and fixing of the packaging bag.

[0046] Furthermore, the distance between the adjacent sub-rod pairs is equal to the front-rear moving distance of the bag pulling mechanism. The spacing between the adjacent sub-rod pairs is equal to the moving distance of the bag pulling mechanism, so that when the bag pulling mechanism moves, the bag clamping mechanism can accurately clamp the packaging bag.

[0047] Furthermore, the distance between the first sub-rod and the second sub-rod is slightly smaller than the bag width of the packaging bag. The distance between the first sub-rod and the second sub-rod is slightly smaller than the bag width of the packaging bag, so that when the first sub-rod and the second sub-rod clamp the packaging bag, the clamping fixing point is located inside the edge of the packaging bag, thereby avoiding affecting the subsequent loading of the packaging bag.

[0048] Anything not described in the present invention can be achieved by adopting or drawing on existing technologies.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
