[0023] To describe in detail the technical content, structural features, achieved purposes and functions of the present application, the technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings in the embodiments of the present application.

[0024] In the present application, spatial relative terms such as "under", "below", "beneath", "lower", "above", "upper", "on", "higher", "side" (for example, as in "side wall") are used to describe the relationship between one element and another (other) element as shown in the accompanying drawings. The spatial relative terms are intended to include different orientations of the device in use, operation and / or manufacture in addition to the orientation depicted in the accompanying drawings. For example, if the device in the accompanying drawings is flipped, the element described as "under" or "beneath" other elements or features will subsequently be positioned "above" the other elements or features. Therefore, the exemplary term "under" can include both the upper and lower orientations. In addition, the device can be positioned otherwise (for example, rotated 90 degrees or in other orientations), and accordingly, the spatial relative descriptive terms used herein are interpreted.

[0025] Refer to Figures 1-3 , the present utility model provides an automatic flanging device 100, which can flange the edge of the bag mouth to facilitate the sewing of the bag mouth. As shown in the figure, the automatic flanging device 100 includes a support column 1, a first mounting plate 2 and a second mounting plate 3 fixed on the support column 1, a first pressing belt plate 4 and a second pressing belt plate 5 rotatably mounted on the first mounting plate 2 and the second mounting plate 3 respectively, a flanging plate 6 rotatably mounted on the first pressing belt plate 4, and a plurality of driving components for driving the first and second pressing belt plates to rotate. Among them, the automatic flanging device 100 has an open state in which the first and second pressing belt plates are opened (such as Figure 1), and the closing state of the first and second pressing plates (such as Figure 3 ).

[0026] The support column 1 includes a base portion 11 and a column portion 12 that is vertically connected to the base portion 11. The base portion 11 is composed of two substantially right-angled pipe bodies. When viewed in the vertical direction, the first and second pressing plates and the respective driving components are located between the two pipe bodies, thereby increasing the stability of the automatic hemming device 100 and preventing it from tipping over.

[0027] The first mounting plate 2 and the second mounting plate 3 are mounted on the column portion 12 of the support column 1 in an up-and-down relative manner. The lower first mounting plate 2 includes a first connecting portion 21 that extends horizontally and a first positioning portion 22 that extends vertically. The first connecting portion 21 is fixedly connected to the support column 1, and the first positioning portion 22 is used to support the first pressing plate 4 and the corresponding driving components. Among them, a first reinforcing rib 23 is also arranged on the first connecting portion 21 to enhance the strength of the first mounting plate 2.

[0028] Similarly, the second mounting plate 3 also has a second connecting portion 31, a second positioning portion 32, and a second reinforcing rib 33, which will not be elaborated here.

[0029] The first pressing plate 4 is rotatably connected to the positioning portion 22, and it includes a first plate body 41 and a first side edge 42 that is perpendicular to the first plate body 41. In this embodiment, the component for driving the first pressing plate 4 is a first cylinder 7. The first cylinder 7 has a first cylinder body (not labeled in the figure) that is rotatably mounted on the first positioning portion 22 and a first cylinder shaft (not labeled in the figure) that can be telescoped relative to the first cylinder body. The first cylinder shaft is rotatably connected to the first pressing plate 4. Thus, by the action of the first cylinder 7, the first pressing plate 4 can be driven to rotate. In other embodiments, devices such as motors, oil pumps, and electromagnetic actuators can also be used to drive the first pressing plate to rotate.

[0030] Similarly, the second pressing plate 5 is rotatably connected to the second positioning portion 32, and it includes a second plate body 51 and a second side edge 52 that is perpendicular to the second plate body 51. In this embodiment, the driving component for driving the second pressing plate 5 is a second cylinder 8. The second cylinder 8 has a second cylinder body (not labeled in the figure) that is rotatably mounted on the second positioning portion 32 and a second cylinder shaft (not labeled in the figure) that can be telescoped relative to the second cylinder body. The second cylinder shaft is rotatably connected to the second pressing plate 5. Thus, by the action of the second cylinder 8, the second pressing plate 5 can be driven to rotate. In other embodiments, devices such as motors, oil pumps, and electromagnetic actuators can also be used to drive the second pressing plate to rotate.

[0031] The first and second plate bodies are each configured to be suitable for pressing against the bag mouth. When the automatic hemming device 100 is in the closed state, the first and second plate bodies are in contact, and the end of the second plate body (the end on the side away from the second positioning portion 32) protrudes outward relative to the first plate body 41 to drive the hemming plate 6 to rotate.

[0032] The hemming plate 6 is rotatably connected to the first side edge 42 of the first pressing belt plate 4. The hemming plate 6 includes a third plate body 61 and a driving member 62 fixed to the end of the third plate body 61 (the end away from the first positioning portion 22). The third plate body 61 is configured to be suitable for hemming the bag mouth. The third plate body 61 extends in the same direction as the first plate body 41, and the driving member 62 is located outside the first plate body 41 and can be contacted by the second plate body 51 when the automatic hemming device 100 is in the closed state.

[0033] The working principle of the automatic hemming device 100 is described as follows: When hemming operation is required, the automatic hemming device 100 is first in the open state to facilitate placing the bag mouth between the first and second hemming plates. Then, the first cylinder 7 acts to push the first pressing belt plate 4 to the horizontal position; then, the second cylinder 8 acts, and the second pressing belt plate 5 rotates towards the first pressing belt plate 4 until the first and second plate bodies are in contact to press against the bag mouth from both sides. Thus, the automatic hemming device 100 switches from the open state to the closed state. During this period, the second plate body 51 contacts and presses against the driving member 62 of the hemming plate 6, whereby the hemming plate 6 flips until the third plate body 61 contacts the end surface of the second plate body 51 on the side away from the first plate body 41. Thus, the third plate body 61 flips the bag mouth to complete the hemming operation.

[0034] The above embodiments are only for illustrating the technical concept and features of the present application, and the purpose is to enable those skilled in the art to understand the content of the present application and implement it accordingly, and it should not be used to limit the protection scope of the present application. Any equivalent changes or modifications made according to the spirit of the present application should be covered within the protection scope of the present application.
