[0018] The utility model is further described below in conjunction with the accompanying drawings. The accompanying drawings are only used for exemplary description and cannot be understood as limiting the present patent.

[0019] In order to more concisely describe the present embodiment, some parts known to those skilled in the art but not related to the main content of the present invention are omitted in the drawings or descriptions. In addition, for the convenience of description, some parts in the drawings are omitted, enlarged or reduced, but they do not represent the size or entire structure of the actual product.

[0020] A material setting mechanism for a bag opening machine, such as Figure 1 As shown, it includes a connecting plate 1, an external pressure frame 2 and a small pressure frame 3. The small pressure frame 3 is arranged above the external pressure frame 2. The external pressure frame 2 and the small pressure frame 3 are correspondingly provided with a bag opening processing window 4; the external pressure frame 2 and the small pressure frame 3 are arranged on the connecting plate 1 in a liftable manner; the above arrangements all belong to the prior art.

[0021] like Figure 3 , Figure 5 As shown, a folding pressing plate 6 is also arranged at the bottom of the outer pressure frame 2, and an opening driving part 5 is arranged on the outer pressure frame 2 to be connected with the folding pressing plate 6. The folding pressing plate 6 is arranged with a sewing window 63 cooperating with the bag opening processing window 4. The sewing window 63 is located below the processing window 4 and is connected thereto, and the connected portion is the sewing portion of the bag opening cloth piece.

[0022] The folding edge pressing piece 6 can have various designs, such as Figure 2 , Figure 4 Two design schemes are provided, but it does not mean that the structure of the folding pressing piece 6 of the present invention is limited to these two schemes.

[0023] like Figure 2 The folding pressing piece 6 shown in the figure has a fixing portion 61 disposed outside the sewing window 63, an opening portion 62 disposed inside the sewing window 63, and an opening driving portion 5 disposed inside the outer pressing frame 2; the fixing portion 61 is fixedly connected to the outer side of the bottom of the outer pressing frame 2, and the opening portion 62 is connected to the opening driving portion 5 disposed inside the outer pressing frame 2. Two opening driving portions 5 are provided, and are respectively connected to two corners of the opening portion 62.

[0024] like Figure 4 The folding pressing piece 6 shown in the figure has an opening portion 62 which is two clamping arms extending from both sides of the sewing window 63 to the inner side of the outer pressing frame 2. Two opening driving portions 5 are arranged inside the outer pressing frame 2 and are respectively connected to the two clamping arms.

[0025] The opening drive unit 5 may be a cylinder or a servo motor.

[0026] The utility model is applied to a bag opening machine and cooperates with a bag opening folding device. After the outer pressure frame 2 and the small pressure frame 3 of the material fixing mechanism of the utility model clamp the bag opening cloth piece to the cutting station at the processing window 4 to cut the bag opening, when the bag opening folding device folds the cut bag opening, the opening driving unit 5 pushes the opening part 62 of the folding edge pressing piece 6 to open from the bottom of the outer pressure frame 2, so that the folded edge of the bag opening enters the gap between the folding edge pressing piece 6 and the outer pressure frame 2. After the folding process is completed, the opening driving unit 5 pulls the opening part 62 to reset, and the opening part 62 is again close to the bottom of the outer pressure frame 2. Under the joint action of the elasticity of the folding edge pressing piece 6 itself and the mechanical pulling force of the opening driving unit 5, the folded edge of the bag opening is tightly clamped between the outer pressure frame 2 and the folding edge pressing piece 6, thereby achieving the effect of fixing the bag opening, preventing displacement and deformation, and the bag opening can be kept fixed, prevented from displacement and deformation during the movement of the material fixing mechanism. The material setting mechanism stacks the folded bag opening cloth piece with bag eyebrows, bag cloth or zipper and other accessories and transports them to the sewing station for sewing through the through-portion of the processing window 4 and the sewing window 63.

[0027] The folding pressing piece 36 of the utility model has a fixing and maintaining function on the shape of the bag mouth after the bag mouth is folded. Compared with the shaping pressing block in the prior art, it has a simple structure and a good fixing and maintaining effect, and greatly reduces the unqualified rate of finished products.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the scope of implementation of the present invention. That is, any equivalent changes and modifications made according to the content of the patent application scope of the present invention should be within the technical scope of the present invention.
