[0018] like Figure 1 and Figure 2 As shown, the present invention discloses a secondary material feeding mechanism for a bag opening sewing machine, comprising a material feeding mounting base 1 installed under the worktable of the bag opening sewing machine, a material feeding lifting base 2 capable of vertical movement above the material feeding mounting base 1, and a material feeding lifting cylinder 3 fixed on the material feeding mounting base 1. A material feeding plate 4 capable of horizontal movement is provided above the material feeding lifting base 2, and the material feeding plate 4 is connected to a material feeding front-to-back drive cylinder 5 fixed on the material feeding lifting base 2. A material insertion plate 6 capable of vertical movement is provided on one side of the material feeding lifting base 2, and the material feeding plate 4 has an insertion groove 4a through which the material insertion plate 6 passes.

[0019] Below the material support plate 4 is a material support moving plate 7, and the material support lifting seat 2 is equipped with a horizontally arranged material support moving guide rail 8. The lower surface of the material support moving plate 7 is equipped with a material support moving slider 9 that moves in conjunction with the material support moving guide rail 8, allowing the material support plate 4 to move horizontally along the material support moving guide rail 8. The drive rod of the material support front and rear drive cylinder 5 is connected to the material support moving plate 7, and the material support front and rear drive cylinder 5 drives the material support moving plate 7 to move horizontally, which in turn drives the material support plate 4 to move horizontally.

[0020] The material lifting seat 2 has a material insertion connecting plate 10 on one side, and a vertically arranged material insertion lifting guide rail 11 on the front side of the material insertion connecting plate 10. The material insertion plate 6 is installed on the material insertion moving plate, and the material insertion moving plate is equipped with a material insertion lifting slider that cooperates with the material insertion lifting guide rail 11. The material insertion plate 6 can move up and down along the material insertion lifting guide rail 11.

[0021] An inserting cylinder 12 is installed on the inserting connecting plate 10. The drive rod of the inserting cylinder 12 is connected to the inserting moving plate through the inserting cylinder connector 13. The inserting cylinder 12 drives the inserting plate 6 to move upward. The inserting plate 6 passes through the inserting groove 4a on the support plate 4 and then cooperates with the pressing mechanism.

[0022] like Figures 3 to 4 As shown, the pressing mechanism of the bag opening sewing machine includes a pressing mounting base 14, which has a lifting pressing plate 15. The pressing plate 15 has a bag opening cutting groove 15a, and a first clamping plate 16 and a second clamping plate 17 that can be opened and closed are provided at the bag opening cutting groove 15a. The pressing plate 15 is provided with a first cylinder 18 for driving the first clamping plate 16 to open and close, and a second cylinder 19 for driving the second clamping plate 17 to open and close. The bottom of the pressing plate 15 is provided with a first clamping plate 20 and a second clamping plate 21 that can open relative to the pressing plate 15. The pressing plate 15 is provided with a first clamping cylinder 22 for driving the first clamping plate 20 to open and close, and a second clamping cylinder 23 for driving the second clamping plate 21 to open and close.

[0023] The pressure plate 15 has a first clamping groove 15b, and the first clamping plate 20 has a second clamping groove 20a corresponding to the first clamping groove 15b. The inserting plate 6 in the secondary material support mechanism drives the material upward through the first clamping groove 15b and the second clamping groove 20a. A third clamping plate 24 that can move back and forth is provided at the first clamping groove 15b, and the pressure plate 15 has a third clamping cylinder 25 for driving the third clamping plate 24 to move back and forth.

[0024] After the first stitching is completed, the material support plate 4 rises to support the material and, following the pressing mechanism, delivers the material to the material placement and positioning mechanism to overlap with the pre-placed backing. Because the material edges below the pressing plate 15 naturally droop, folding may occur during movement, affecting the quality of the second stitching. Therefore, the pressing mechanism and the secondary material support mechanism need to work together to secure the material edges below the pressing plate 15.

[0025] The material support plate 4 of the secondary material support mechanism rises upward to support the material, and moves horizontally between the material feeding position and the sewing position. The insert plate 6 rises synchronously with the material support plate 4, and the insert cylinder 12 drives the insert plate 6 to move upward. The insert plate 6 inserts the edge of the material below the pressure plate 15 into the first clamping groove 15b of the pressure mechanism. The third clamping cylinder 25 drives the third clamping plate 24 to move towards the first clamping groove 15b, clamping and fixing the edge of the material in the first clamping groove 15b.

[0026] The pressure plate 15 has a bag opening cutting groove 15a with a third clamping plate 26 and a fourth clamping plate 27 that can be opened and closed. The pressure plate 15 is equipped with a third cylinder 28 for driving the third clamping plate 26 to open and close, and a fourth cylinder 29 for driving the fourth clamping plate 27 to open and close. The first clamping plate 16, the second clamping plate 17, the third clamping plate 26, and the fourth clamping plate 27 cooperate with the bag folding mechanism to complete the bag folding.

[0027] The pressure plate 15 is slidably equipped with a first clamping seat 30 and a second clamping seat 31. The first clamping plate 20 is rotatably mounted at the end of the first clamping seat, and the second clamping plate 21 is rotatably mounted at the end of the second clamping seat. The pressure plate 15 is equipped with a first driving cylinder 32 and a second driving cylinder 33. The driving rod of the first driving cylinder 32 is connected to the first clamping seat 30, and the driving rod of the second driving cylinder 33 is connected to the second clamping seat 31. The first driving cylinder 32 drives the first clamping plate 20, and the second driving cylinder 33 drives the second clamping plate 21 to press and straighten the fabric at the folded bag opening edge, improving the sewing effect.

[0028] The first clamping cylinder 22 is rotatably mounted at the end of the first clamping seat 30, and the drive rod of the first clamping cylinder 22 is connected to the first clamping plate 20. The second clamping cylinder 23 is rotatably mounted at the end of the second clamping seat 31, and the drive rod of the second clamping cylinder 23 is connected to the second clamping plate 21.

[0029] The pressure plate 15 is slidably mounted on the pressure mounting base 14 via the vertical connecting plate 34. The pressure mounting base 14 is provided with a first pressure driving cylinder 35 for driving the vertical connecting plate 34 to rise and fall. The vertical connecting plate 34 is provided with a front pressure frame 36 and a rear pressure frame 37 that can rise and fall above the pressure plate 15.

[0030] The vertical connecting plate 34 is provided with a pressing lifting seat 38 that can move up and down and a second pressing driving cylinder 39 for driving the pressing lifting seat 38 to move up and down. The front end of the pressing lifting seat 38 is fixedly connected to the front pressing frame 36. The front end of the pressing lifting seat 38 is provided with a rear pressing frame 37 that can move up and down and a rear pressing frame lifting cylinder 40 for driving the rear pressing frame 37 to move up and down.

[0031] The vertical connecting plate 34 is equipped with a third drive cylinder 41, and the drive rod of the third drive cylinder 41 is connected to the pressing lifting seat 38. After the bag is folded, the first clamping plate 16 and the second clamping plate 17 open relative to each other, and the third clamping plate 26 and the fourth clamping plate 27 open relative to each other. At this time, there is still a gap between the two layers of bag opening fabric. The third drive cylinder 41 drives the front pressure plate and the rear pressure plate to press the bag opening fabric downward.

[0032] The vertical connecting plate 34 is fixed with a first locking cylinder 43 for connecting the mop plate 42, which is used to support the material at the feeding position. When the pressing mechanism moves to the feeding position, the first locking cylinder 43 is connected and fixed to the mop plate 42, and the pressing mechanism moves the material to the sewing position. After the sewing is completed, the first locking cylinder 43 is disengaged from the mop plate 42, and the mop plate 42 is pulled out by the supporting mechanism and moved to the feeding position to wait for the next feeding.

[0033] The preferred embodiment of this utility model has been described, and various changes or modifications made by those skilled in the art will not depart from the scope of this utility model.
