DETAILED DESCRIPTION

[0023] 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.

[0024] 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.

[0025] A material metering device for a bag opening machine, such as Figure 1 As shown, it includes a connecting plate 1, a material placing plate 2 and a pressing frame 3. The material placing plate 2 and the pressing frame 3 are arranged on the connecting plate 1 through a lifting mechanism; the pressing frame 3 is driven by the lifting mechanism to rise and fall above the material placing plate 2. When the material placing plate 2 needs to place cloth, the pressing frame 3 rises upward. When entering the processing program, the pressing frame 3 descends and presses on the material placing plate 2 to press the cloth to be processed.

[0026] like Figure 2 As shown, the material placing plate 2 is provided with a first processing window 41. Figure 1 As shown, the pressing frame 3 is correspondingly provided with a second processing window 42. When the pressing frame 3 is lowered and pressed against the material placing plate 2, the second processing window 42 overlaps with the first processing window 41 and falls within the range of the first processing window 41. The processing of the bag mouth is based on the second processing window 42. The processing window is mostly set to be similar to a long rectangular frame shape.

[0027] like Figure 2 As shown, the bottom of the material placing plate 2 is provided with an embedding groove 21, and the embedding groove 21 is provided with Figure 3 The shape and size of the folding pressing piece 6 and the embedding groove 21 are consistent with the folding pressing piece 6. The folding pressing piece 6 is installed in the embedding groove 21, and the bottom surface of the folding pressing piece 6 is flush with the bottom of the material placing plate 2. In this way, the bag opening folding edge is clamped more firmly after being pressed in.

[0028] The folding pressing piece 6 is provided with a third processing window 43 matching with the first processing window 41 and the second processing window 42 , and an opening drive unit 5 connected to the folding pressing piece 6 is also provided inside the material placing plate 2 ; the opening drive unit 5 is provided with a cylinder or a servo motor.

[0029] Preferably, if Figure 3 As shown, a fixing portion 61 is arranged outside the third processing window 43 of the folding pressing sheet 6, and an opening portion 62 is arranged inside the third processing window 43 of the folding pressing sheet 6; preferably, as Figure 3As shown, the opening portion 62 is two clamping arms extending from both sides of the third processing window 43 to the inner side of the material placing plate 2. The opening portion 62 is arranged on the inner side of the embedding groove 21, and the fixing portion 61 is fixedly arranged on the outer side of the embedding groove 21. Two opening driving portions 5 are arranged on the inner side of the material placing plate 2 and are respectively connected to the two clamping arms of the opening portion 62.

[0030] The function of the folding pressing piece 6 is that when the bag mouth folding device folds the cut bag mouth, the opening driving unit 5 pushes the opening part 62 of the folding pressing piece 6 to open from the embedding groove 21 at the bottom of the feeding plate 2, so that the folded edge of the bag mouth enters the gap between the folding pressing piece 6 and the embedding groove 21. After the folding process is completed, the opening driving unit 5 pulls the opening part 62 to reset, and the opening part 62 is re-embedded in the embedding groove 21. Under the combined effect of the elasticity of the folding pressing piece 6 itself and the mechanical pulling force of the opening driving unit 5, the folded edge of the bag mouth is tightly clamped between the feeding plate 2 and the folding pressing piece 6, thereby achieving the effect of fixing the bag mouth, preventing displacement and deformation, and the bag mouth can be kept fixed, prevented from displacement and deformation during the movement of the fixing mechanism.

[0031] like Figure 4 As shown, the pressing frame 3 includes an outer pressing frame 31, an inner pressing plate 32 and an inner pressing plate lifting mechanism 33, and the inner pressing plate lifting mechanism 33 drives the inner pressing plate 32 to rise and fall relative to the outer pressing frame 31; the outer edge of the inner pressing plate 32 and the bottom edge of the outer pressing frame 31 and the two side edges of the outer pressing frame 31 form a rectangular second processing window 42, the bottom edge of the outer pressing frame 31 is provided with a first pressing plate 311 bent toward the first processing window 41, and the outer edge of the inner pressing plate 32 is provided with a second pressing plate 321 bent toward the first processing window 41; when the material placing plate 2 is placed on the material placing plate 2, the pressing frame 3 descends, and the first pressing plate 311 and the second pressing plate 321 press the material into the first processing window 41, so that the material is not easy to move.

[0032] In actual application, the first pressing plate 311 and the second pressing plate 321 are pressed down at the same time, and the middle of the cloth is easy to bulge. To solve this problem, Figure 4 As shown, the outer pressure frame 31 is provided with an inner pressure plate lifting mechanism 33 , the inner pressure plate lifting mechanism 33 is provided with a mounting plate 34 , and the inner pressure plate 32 is arranged on the mounting plate 34 .

[0033] After the cloth is placed on the placing plate 2, the pressing frame 3 is pressed down, driving the outer pressing frame 31 to descend, thereby driving the first pressing plate 311 to insert into the first processing window 41 and the third processing window 43, pressing the cloth, and then the inner pressing plate lifting mechanism 33 drives the inner pressing plate 32 to descend, driving the second pressing plate 321 to insert into the first processing window 41 and the third processing window 43, and then pressing against the cloth, so as to ensure that there is no bulge in the middle of the cloth.

[0034] To increase the friction between the first pressing plate 311 and the second pressing plate 321 and the cloth, Figure 5As shown, the bottom of the first pressing plate 311 and the bottom of the second pressing plate 321 are both configured to be serrated, and the serrated structure presses on the cloth, making it more difficult for the cloth to move.

[0035] In order to further press the fabric so that it does not shift, Figure 3 As shown, the outer long side 431 of the third processing window of the folding pressing plate 6 is set to be a sawtooth shape that matches the bottom of the first pressing plate 311, and the inner long side 432 of the third processing window is set to be a sawtooth shape that matches the bottom of the second pressing plate 321. In this way, when the cloth is pressed down by the first pressing plate 311 and the second pressing plate 321, the saw teeth of the first pressing plate 311 and the second pressing plate 321 are engaged with the saw teeth of the third processing window 43, and the cloth is firmly fixed without the possibility of deviation.

[0036] The utility model also solves the problem of universality, that is, one bag opening machine needs to meet the needs of processing bags of various sizes. Figure 4 As shown, long first mounting holes 35 or grooves are symmetrically arranged on both sides of the mounting plate 34, and the inner pressure plate 32 is adjustably arranged on the mounting plate 34 by being fixed at different positions of the first mounting holes 35 or grooves to adjust the width of the second processing window 42 to meet different size requirements.

[0037] In order to further meet more size requirements, long strip-shaped second mounting holes 36 or grooves are longitudinally symmetrically arranged on both sides of the inner pressure plate 32, and the second pressing plate 321 is fixed at different positions of the second mounting holes 36 or grooves to be adjustably mounted on the bottom of the inner pressure plate 32. In this way, further adjustment is achieved on the basis of the adjustability of the inner pressure plate 32 to meet more size requirements.

[0038] 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.
