[0022] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0023] See also Figure 1—4. A feeding mechanism for a drawstring bag, comprising a first frame 1 and a feeding frame 2. The first frame 1 is provided with a cloth driving mechanism 3, a folding tube 4 and an automatic sewing machine 5. The feeding frame 2 is provided with a cloth roll. The folding tube 4 is provided with a folding groove 41. The cloth driving mechanism 3 drives the cloth to pass through the folding tube 4, and the two sides of the cloth are bent into shape through the folding groove 41, and the two sides of the cloth are sewed and fixed by the automatic sewing machine 5.

[0024] Specifically, the feeding rack 2 is arranged on one side of the first frame 1, and a guide roller is arranged on the feeding rack 2, and the guide roller is fixedly installed on the feeding rack 2 through a support member, and the cloth inside the cloth roll arranged on the feeding rack 2 is connected to the cloth driving mechanism 3 through the guide roller. Specifically, the number of the cloth driving mechanisms 3 is two, one of which is arranged at one end of the first frame 1 close to the feeding rack 2, and the other cloth driving mechanism 3 is arranged at one end of the first frame 1 away from the feeding rack 2. The cloth can be transported by the two cloth driving mechanisms 3, and the folding drum 4 is fixedly installed on the feeding rack 2. On the first frame 1, a folding groove 41 is opened inside the folding tube 4. Specifically, the folding groove 41 can be a rectangular structure or a "U"-shaped structure with both ends folded inward, and the opening at one end of the folding tube 4 is large, and the opening at the other end is small, so that when the cloth passes through the folding groove 41 inside the folding tube 4, the two ends of the cloth in the width direction will bend inward along the shape of the inside of the folding groove 41, so that the two sides of the cloth are folded inward, and then under the drive of the cloth driving mechanism 3, the folded cloth is moved to the automatic sewing machine 5, and the automatic sewing machine 5 can sew the two sides of the folded cloth.

[0025] The utility model drives the cloth in the cloth roll to unwind and bend it into shape through the folding tube 4 through the cloth driving mechanism 3, and sews and fixes the two sides of the cloth through the automatic sewing machine 5, so that the two sides of the cloth can be automatically folded and sewn, instead of folding the cloth manually, with high efficiency, fast speed and good production benefits. At the same time, since the cloth is directly folded and sewn, the size of the produced cloth can be adjusted after the two sides are fixed, so that the depth size of the produced drawstring bag can be flexibly adjusted.

[0026] Further, such as Figure 1 As shown, the feeding rack 2 includes a fixed frame 21, a rotating frame 22 and a driving unit 23. Specifically, the driving unit 23 is a telescopic cylinder. An adapter seat 25 is fixedly installed on the fixed frame 21. A clamping groove 24 is opened at one end of the rotating frame 22, and the other end of the rotating frame 22 is rotatably connected to the fixed frame 21. One end of the driving unit 23 is rotatably connected to the adapter seat 25, and the other end of the driving unit 23 is rotatably connected to the rotating frame 22. By keeping the output end of the driving unit 23 telescopic, the rotating frame 22 can be driven to rotate around the fixed frame 21, so that it is convenient for the operator to place the cloth roll into the clamping groove 24 or adjust the tension of the cloth roll.

[0027] As an embodiment provided by the utility model, the cloth driving mechanism 3 includes a driving motor 31, a driving roller 32, a driven roller 33, a mounting frame 34 and a supporting frame 35, wherein the driving motor 31 is fixedly mounted on the outer wall at the top of the first frame 1, and the supporting frame 35 and the mounting frame 34 are both fixedly mounted on the top of the first frame 1, the driving roller 32 is rotatably connected to the supporting frame 35, and one end of the driving roller 32 is in transmission connection with the driving motor 31, a lifting unit 36 ​​is fixedly mounted on the outer wall on one side of the mounting frame 34, and a connecting bracket 37 is fixedly mounted on the output end of the lifting unit 36, the driven roller 33 is rotatably connected to the connecting bracket 37, and the connecting bracket 37 can be driven to keep lifting by the lifting unit 36, so that the spacing between the driven roller 33 and the driving roller 32 can be adjusted, which can facilitate the operator to pass the cloth roll through the driven roller 33 and the driving roller 32;

[0028] Preferably, there are two cloth driving mechanisms 3 , and both cloth driving mechanisms 3 are mounted on the first frame 1 .

[0029] As a further embodiment provided by the present utility model, Figure 1 As shown, the folding cylinder 4 is fixedly installed on the top of the first frame 1 through a support, and the folding cylinder 4 is installed between two cloth driving mechanisms 3. The second frame 9 is fixedly installed on the first frame 1, and the automatic sewing machine 5 is fixedly installed on the outer wall of one side of the second frame 9.

[0030] like Figure 1 and Figure 2 As shown, a support plate 6 is arranged between the folding tube 4 and one of the cloth driving mechanisms 3, and a limit plate 61 is fixedly installed on the support plate 6. The limit plate 61 and the support plate 6 are distributed at a predetermined interval. The cloth passes between the limit plate 61 and the support plate 6, and then passes through the folding tube 4. The cloth can be flattened by the limit plate 61 and the support plate 6 to reduce cloth wrinkles and facilitate the cloth to enter the folding tube 4.

[0031] Further, as an embodiment provided by the utility model, Figure 3As shown, a cutting mechanism 8 is provided at the end of the first frame 1, and the cutting mechanism 8 includes a cutting bracket 81, a transverse movement unit 82, a pressing unit 83 and a cutting motor 84. The cutting bracket 81 is fixedly installed on the outer wall of the first frame 1, and the transverse movement unit 82 is fixedly installed on the cutting bracket 81. The cutting motor 84 is fixedly installed on the output end of the transverse movement unit 82, and the pressing unit 83 is fixedly installed on the cutting bracket 81. The pressing unit 83 is specifically a cylinder, and a pressing plate 85 is fixed at its output end. The pressing plate 85 can be used to fix the cloth on the supporting plate of the first frame 1 to prevent the cloth from curling during cutting. There are two pressing units 83, one of which is arranged on the cutting bracket 81, and the other is arranged on another cloth driving mechanism 3. It should be pointed out that the transverse movement unit 82 can be a conventional mechanical component such as a linear drive module or a cylinder.

[0032] Working principle:

[0033] The cloth roll is placed in the rotating frame 22 24 , and the cloth needs to be manually passed through the first cloth driving mechanism 3 , the support plate 6 , the hemming cylinder 4 , the automatic sewing machine 5 , another cloth driving mechanism 3 and the cutting mechanism 8 in sequence for the first time;

[0034] The cloth can be unwound by two cloth driving mechanisms 3. When the cloth passes through the hemming groove 41 of the hemming cylinder 4, the two sides of the cloth are folded inwards and sewn by the automatic sewing machine 5.

[0035] The continuous cloth can be cut into individual pieces by the cutting mechanism 8, so that the size of the produced cloth bags can be quickly changed.

[0036] Those skilled in the art will appreciate that other similar connection methods may also be used to implement the present invention, such as welding, bonding or screwing.

[0037] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
