[0024] As shown in the figure, a fabric clamping and folding device of an automatic sewing bag cover machine includes a needle plate assembly, a folding material assembly and a bag type plate assembly. The needle plate assembly and the bag type plate assembly are on the same horizontal plane, and the folding material assembly is vertically arranged on one side of the needle plate assembly.

[0025] The needle plate assembly includes a needle plate main body 1, a fabric template 2 arranged on the upper surface of the needle plate main body 1, and a first lifting cylinder 3 arranged on the lower surface of the needle plate main body 1. A first connecting plate 4 and a second connecting plate 5 are fixedly arranged on the upper surface of the needle plate main body 1. The fabric template 2 is arranged between the first connecting plate 4 and the second connecting plate 5. The edge of the fabric template 2 is fixedly connected to the first connecting plate 4 through a template frame 6. A lifting support plate 7 is arranged on the lower surface of the fabric template 2, and the lifting support plate 7 is slidably connected to the first lifting cylinder 3 up and down.

[0026] The folding material component includes an upper folding shovel module 8 and a lower folding shovel module 9 arranged in parallel. The upper folding shovel module 8 is fixedly connected with a mounting seat 10. The lower folding shovel module 9 is slidably connected with the mounting seat 10 through a second lifting cylinder 11. The mounting seat 10 is connected with a Y-axis linear module 12, and the Y-axis linear module 12 is connected with a Z-axis lifting module 13. The upper folding shovel module 8 and the lower folding shovel module 9 have the same structure. The upper folding shovel module 8 includes a U-shaped bottom plate 14 and folding knives 15 arranged around the U-shaped bottom plate 14. A third driving cylinder 16 corresponding to the folding knives 15 is arranged on the outer edge of the U-shaped bottom plate 14.

[0027] The bag-shaped plate component includes a fixed seat 17, an upper bag-shaped plate 18 and a lower bag-shaped plate 19 arranged in parallel on the upper surface of the fixed seat 17. A first slide rail 20 and a second slide rail 21 are arranged on the upper surface of the fixed seat 17. The first slide rail 20 is slidably connected with the upper bag-shaped plate 18, and the second slide rail 21 is slidably connected with the lower bag-shaped plate 19. The upper bag-shaped plate 18 is slidably connected with the first slide rail 20 up and down through a fourth lifting cylinder 22, and the lower bag-shaped plate 19 is slidably connected with the second slide rail 21 up and down through a fifth lifting cylinder 23.

[0028] The bottom surface of the lower bag-shaped plate 19 is in contact with the upper surface of the needle plate component. Specifically, the lower bag-shaped plate 19 extends along the direction of the first slide rail 20. The bottom surface of the lower bag-shaped plate 19 moves along the needle plate main body 1 to the directly above the fabric template 2. The fifth lifting cylinder 23 can drive the lower bag-shaped plate 19 to press down to fit with the fabric template 2. The upper surface of the fabric template 2 is used to place the first piece of fabric. When the lower bag-shaped plate 19 presses down, it clamps the first piece of fabric and makes the edge of the first piece of fabric upturn, which is convenient for the inward hemming of the first piece of fabric.

[0029] The bottom surface of the upper bag-shaped plate 18 is in contact with the upper surface of the upper folding shovel module 8. Specifically, the upper bag-shaped plate 18 extends along the direction of the second slide rail 21. The top surface of the upper bag-shaped plate 18 is used to place the second piece of fabric. A clamp 24 is arranged at the edge of the top surface of the upper bag-shaped plate 18 to prevent the second piece of fabric from shifting. The bottom surface of the upper bag-shaped plate 18 moves along the inner circle of the U-shaped bottom plate 14 to the directly below the folding knives 15. The fourth lifting cylinder 22 can drive the upper bag-shaped plate 18 to lift, that is, the edge of the first piece of fabric downturns and contacts the folding knives 15, which is convenient for the inward hemming of the second piece of fabric.

[0030] During the actual use process, an operator places the first piece of fabric on the fabric template 2. The first lifting cylinder 3 drives the fabric template 2 to descend, so that the top surface of the fabric template 2 is slightly lower than the upper surface of the needle plate main body 1. The bottom surface of the lower bag-shaped plate 19 moves along the needle plate main body 1 to the directly above the fabric template 2. The fifth lifting cylinder 23 drives the lower bag-shaped plate 19 to press down, making the edge of the first piece of fabric upturn.

[0031] The upper pocket template 18 extends above the lower pocket template 19 along the direction of the second slide rail 21. An operator places the second piece of fabric on the upper pocket template 18 and fixes it using the fixture 24. The Z-axis lifting module 13 drives the Y-axis linear module 12 to descend. At the same time, the Y-axis linear module 12 drives the mounting seat 10 to move forward until the upper folding shovel module 8 and the lower folding shovel module 9 are located directly above the fabric template 2. The second lifting cylinder 11 drives the lower folding shovel module 9 to press down, so that the folding knife 15 is located at the edge of the first piece of fabric. The fourth lifting cylinder 22 drives the upper pocket template 18 to lift, so that the folding knife 15 contacts the upper surface edge of the first piece of fabric. The third driving cylinder 16 drives the folding knife 15 to extend, so that the edges of both the first piece of fabric and the second piece of fabric are folded inwards.

[0032] After the hemming is completed, the third driving cylinder 16 drives the folding knife 15 to retract. At the same time, the fourth lifting cylinder 22 drives the upper pocket template 18 to press down, so that the first piece of fabric and the second piece of fabric are closely attached. The Z-axis lifting module 13 and the Y-axis linear module 12 drive the mounting seat 10 to reset. The hemmed fabric is clamped through the pressing plate assembly or other devices. At the same time, the lower pocket template 19 and the upper pocket template 18 are sequentially withdrawn and reset. The pressing plate assembly drives the fabric to shift for the sewing process.

[0033] Therefore, the fabric clamping and folding device of the automatic sewing bag cover machine of the present utility model has a reasonable structural design of the folding component and the clamping component, and they cooperate with each other to ensure that the hemmed shapes of the two pieces of fabric are exactly the same, with high practicability.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and are not intended to limit them. Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that they can still modify or equivalently replace the technical solutions of the present utility model, and these modifications or equivalent replacements cannot make the modified technical solutions deviate from the spirit and scope of the technical solutions of the present utility model.
