Embodiment 2

[0055] Based on the above embodiment 1, further description is made.

[0056] Referring to Figure 3 , the side of the main frame 1 is fixedly provided with a welded triangular arm 6;

[0057] The welded triangular arm 6 forms a triangular structure, which can enhance the stability of the main frame 1;

[0058] The middle part of the side edge of the main frame 1 is connected with a sliding frame 101 through bolts.

[0059] When the bolts are not tightened, the sliding frame 101 can slide freely on the side edge of the main frame 1, at this time the height of the sliding frame 101 can be adjusted, and when the bolts are locked, the position of the sliding frame 101 is fixed, at this time the sliding frame 101 can form an integrated stable structure, thereby providing stability for the bag feeding mechanism 2.

[0060] Referring to Figure 1 , the bag feeding clamping cylinder 25 is fixed to the middle position of the sliding frame 101, and the push-out cylinder 26 is fixed to the end position of the sliding frame 101;

[0061] The bag feeding clamping cylinder 25 can be extended and retracted, and during the extension and retraction process, the position of the welded bag feeding clamping workpiece 24 is controlled, when the welded bag feeding clamping workpiece 24 reaches or approaches the maximum extension distance, the packaging bag can be locked to ensure the stability of the packaging bag at the sliding frame 101;

[0062] Similarly, the push-out cylinder 26 can also be extended and retracted, and during the extension and retraction process, the position of the bag feeding motor 22 can be controlled;

[0063] The bag feeding clamping cylinder 25 and the push-out cylinder 26 are arranged in parallel.

[0064] Controlling the parallel arrangement of the bag feeding clamping cylinder 25 and the push-out cylinder 26 can avoid space interaction between the two during work, ensuring the stability of their respective operation.

[0065] Referring to Figure 4And Figure 5 The side of the installation support 2601 and close to the bag feeding motor 22 is fixedly provided with a parallel double rod 2201, and two chain wheels 23 are arranged between the parallel double rod 2201.

[0066] When the bag feeding motor 22 is started, the control chain wheel 23 rotates, at this time, the packaging bag is pushed to move into the main frame 1 or pushed to move out of the main frame 1, and in the process of moving the packaging bag, the parallel double rod 2201 can limit the moving direction of the packaging bag.

[0067] Referring to Figure 6 , Figure 7 , Figure 8 And Figure 9 , the edge folding plate one 10 is fixed to the end of the middle fish eye joint 20, and the edge folding plate two 11 is fixed to the end of the transverse floating joint 18.

[0068] The moving directions of the edge folding plate one 10 and the edge folding plate two 11 are different, when the edge folding operation is performed, the edge folding plate one 10 rotates by 90° along the front end shaft through the edge folding cylinder 21 and the middle fish eye joint 20, and the edge folding plate two 11 connects the sliding block 19 through the edge folding bag supporting cylinder 15 and the connecting plate to realize the bag supporting action, when the bag is supported, the edge folding plate one 10 and the edge folding plate two 11 are on the same small frame and move transversely together, at this time, the unfolding space of the bag opening position of the packaging bag can be ensured to a large extent, and then the subsequent M-shaped edge folding operation is facilitated.

[0069] Referring to Figure 6 , Figure 7 , Figure 8 And Figure 9 , the output end of the edge folding bag supporting cylinder 15 is fixed to one end of the vertical transverse floating joint 18, and one end of the edge folding cylinder 21 is close to the side of the edge folding bag supporting cylinder 15.

[0070] When the edge folding bag supporting cylinder 15 operates, the conveying end cooperates with the transverse floating joint 18 to control the sliding block 19 to move, and then the edge folding plate one 10 and the edge folding plate two 11 are pushed out and further perform the edge folding operation, at the same time, the edge folding cylinder 21 moves synchronously with the output end of the edge folding bag supporting cylinder 15.

[0071] Referring to Figure 6 , Figure 7 , Figure 8 And Figure 9 , the tail of the middle fish eye joint 20 is fixed to the output end of the edge folding cylinder 21, and the end is connected to the edge folding plate one 10 through the connecting shaft.

[0072] When the edge folding cylinder 21 is started, the middle fish eye joint 20 is used to realize the force pushing, and then the edge folding plate one 10 is pressed down, and then the bag opening of the packaging bag is folded into an M-shaped form.

[0073] Referring to Figure 6 , Figure 7 , Figure 8 and Figure 9 , the side of the vertical guide rod 8 is fixedly provided with a copper sleeve 801, and cooperates with the copper sleeve 801 and the limiting fixed plate 5 to form a fixing.

[0074] The vertical guide rod 8 plays a role of guiding and limiting the moving direction when the equipment is working. At this time, when the copper sleeve 801 is clamped into the limiting fixed plate 5, the stability of the connection between the vertical guide rod 8 and the limiting fixed plate 5 can be improved.

[0075] Referring to Figure 6 , Figure 7 , Figure 8 and Figure 9 Figure 6 Figure 7 Figure 8 Figure 9 , one end of the bag holding cylinder 12 is fixedly provided with a mechanical arm mounting seat 1201, and is fixed through the mechanical arm mounting seat 1201 and the top end of the working flat plate 1601.

[0076] By using the mechanical arm mounting seat 1201, the inclination angle of the bag holding cylinder 12 can be adjusted, so as to adapt to the height of the packaging bag of the loaded material during the bag holding operation. Example 3

[0077] Based on the above-mentioned example 1 and example 2, further description is made.

[0078] One end of the bag feeding mechanism 2 is connected with the packaging machine through a conveying belt, and the other end of the bag feeding mechanism 2 is connected with the bag sewing equipment through a conveying belt. Example 4

[0079] Based on the above-mentioned example 1, example 2 and example 3, comprehensive description is made.

[0080] When the whole M-fold automatic edge folding bag feeding equipment is put into use:

[0081] Firstly, the packaging bag is moved into the inside of the main frame 1 by means of an external propelling equipment;

[0082] Then the bag holding and edge folding sinking cylinder 17 is started, cooperates with the vertical floating joint 16, drives the working flat plate 1601 and the whole edge folding mechanism 3 downward, until it is poked into the inside of the packaging bag, then the edge folding cylinder 21 pushes the middle fish eye joint 20, and then controls the activity of the edge folding plate one 10, the transverse floating joint 18 controls the activity of the edge folding plate two 11, realizes the edge folding and supporting of the packaging bag, then when the edge folding cylinder 21 is started, the middle fish eye joint 20 is used to realize the propulsion of force, and then the edge folding plate one 10 is pressed downward, and then the bag opening of the packaging bag is folded into an M-fold form, at this time, the M-fold edge folding operation is completed.

[0083] Then the mechanical hand installation seat 1201 adjusts the inclination angle of the bag holding cylinder 12, the bag holding cylinder 12 works, cooperates with the low fish eye joint 13, controls the bag holding clamp 14, completes the bag holding operation, and then the bag folding sinking cylinder 17 starts and drives the whole folding mechanism 3 to adjust the height lifting;

[0084] Then the push-out cylinder 26 and the bag feeding clamp cylinder 25 in the bag feeding mechanism 2 extend, control the position of the welding type bag feeding clamp workpiece 24, and form clamping of the bag opening.

[0085] Then the folding cylinder 21 releases, and the folding plate one 10 and the folding plate two 11 are pulled out. At this time, the bag feeding motor 22 starts and pushes the packaging bag to move to the inside of the main frame 1. In the packaging bag moving process, the parallel double rod 2201 can limit the moving direction of the packaging bag. After the packaging bag is fed out, each structure returns to the initial position, waiting for the subsequent packaging to arrive in the main frame 1.
