DETAILED DESCRIPTION

[0027] 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.

[0028] 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.

[0029] A bag opening forming device of a bag opening machine, such as Figure 1 As shown, it includes a folding mechanism 2 and a material fixing mechanism 3; the folding mechanism 2 and the material fixing mechanism 3 are arranged on a base 1, and the folding mechanism 2 is arranged above the material fixing mechanism 3 in a liftable manner;

[0030] The base 1 is provided with a Y-axis slide rail 11 and a first driving mechanism 12, and the folding mechanism 2 is provided with a mounting seat 21, which is connected to the Y-axis slide rail 11 and slides along the Y-axis direction under the drive of the first driving mechanism 12; preferably, the first driving mechanism 12 can be a cylinder or a servo motor.

[0031] like Figure 2 , Figure 3 As shown, the folding mechanism 2 includes a knife inserting seat 22, a knife inserting group, a knife inserting slide group and a knife inserting driving mechanism. The knife inserting group is composed of two X-axis knife inserting knives 23 and two Y-axis knife inserting knives 24 arranged in a rectangular shape. The knife inserting slide group is composed of an X-axis knife inserting slide 231 and a Y-axis knife inserting slide 241. The knife inserting driving mechanism includes an X-axis driving component 232 for driving the two X-axis knife inserting knives 23 to open or reset along the X-axis knife inserting slide 231, and a Y-axis driving component 242 for driving the two Y-axis knife inserting knives 24 to open or reset along the Y-axis knife inserting slide 241.

[0032] Furthermore, an X-axis inserting knife lifting component 233 is also provided, and the X-axis inserting knife 23 is connected to the X-axis inserting knife slide rail 231 via the X-axis inserting knife lifting component 233 .

[0033] Preferably, the X-axis driving component 232, the Y-axis driving component 242 and the X-axis inserting knife lifting component 233 can be configured as cylinders or servo motors.

[0034] like Figure 3 As shown, the mounting seat 21 is also provided with a lifting rail 25 and a second driving mechanism in the Z-axis direction. The inserting seat 22 is connected to the lifting rail 25 and is lifted and lowered in the Z-axis direction on the mounting seat 21 under the drive of the second driving mechanism.

[0035] like Figure 1 , Figure 4 As shown, the base 1 is also provided with a Z-axis direction connecting plate 31, and the material setting mechanism 3 is connected to the base 1 via the connecting plate 31;

[0036] like Figure 4As shown, the material fixing mechanism 3 is provided with a small pressure frame 32 and an outer pressure frame 33. The small pressure frame 32 is arranged above the outer pressure frame 33. The outer pressure frame 33 and the small pressure frame 32 are provided with bag opening processing windows 34 correspondingly. The outer pressure frame 33 and the small pressure frame 32 are arranged on the connecting plate 31 so as to be liftable.

[0037] like Figure 4-6 As shown, a folding pressing plate 36 is also provided at the bottom of the outer pressure frame 33. The folding pressing plate 36 is provided with a sewing window 363 cooperating with the bag opening processing window 34. The sewing window 363 is located below the processing window 34 and is connected to the processing window 34. The connected portion is the sewing portion of the bag opening cloth piece.

[0038] The folding edge pressing piece 36 can have various designs, such as Figure 5 , Figure 6 Two design solutions are provided, but this does not mean that the structure of the folding pressing piece 36 of the present invention is limited to these two methods.

[0039] A design such as Figure 5 As shown, the hem pressing piece 36 is provided with a fixing portion 361 outside the sewing window 363, an opening portion 362 is provided inside the sewing window 363, and an opening drive portion 37 is provided inside the external pressure frame 33; the fixing portion 361 is fixedly connected to the outside of the bottom of the external pressure frame 33, and the two inner corners of the opening portion 362 are connected to the two opening drive portions 37 provided inside the external pressure frame 33. Preferably, the opening drive portion 37 is a cylinder. The opening portion 362 can be separated (opened) from the bottom of the external pressure frame 33 under the drive of the opening drive portion 37.

[0040] Another design solution is Figure 6 As shown, the opening portion 362 can also be configured as two clamping arms extending from both sides of the sewing window 363 to the inner side of the outer pressure frame 33, and the top ends of the two clamping arms are respectively connected to an opening driving portion 37. Under the drive of the opening driving portion 37, the clamping arms are separated (opened) from the bottom of the outer pressure frame 33.

[0041] When the utility model is installed on a bag opening machine for use, the bag opening cloth piece is pressed between the outer pressing frame 33 and the small pressing frame 32 by the material fixing mechanism 3, and is transported to the laser cutting machine for bag opening cutting. After the cutting is completed, the folding mechanism 2 is driven by the first driving mechanism 12 to slide to the top of the material fixing mechanism 3 along the Y-axis direction, and the second driving mechanism drives the inserting knife group to insert into the processing window 34 of the material fixing mechanism 3. First, two Y-axis inserting knives 24 are inserted into the processing window 34, and opened along the Y-axis direction under the drive of the Y-axis driving component 242, so that the long side of the cut of the bag opening cloth piece is opened and folded along the Y-axis direction; then, the X-axis inserting knife lifting component 233 descends, and the two X-axis inserting knives 23 are inserted into the processing window 34, and opened along the X-axis direction under the drive of the X-axis driving component 232, so that the short side of the cut of the bag opening cloth piece is opened and folded along the X-axis direction, and the folding process of the cut bag opening is completed.

[0042] During the descending process of the folding mechanism 2, the opening drive unit 37 of the external pressure frame 33 drives the opening portion 362 of the folding pressure plate 36 to move downward and separate from the bottom of the external pressure frame 33, leaving space for the bag folding processing of the folding mechanism 2. After the folding mechanism 2 completes the folding process, the opening drive unit 37 drives the opening portion 362 to reset, and presses the folded edge of the bag mouth to the bottom of the external pressure frame 33. The folded edge of the bag mouth is pressed, stabilized, and does not shift, so as to ensure that the shape of the bag mouth is not deformed when the bag opening cloth piece is transported to the bag eyebrow, bag cloth or zipper and other accessory loading stations.

[0043] After the bag opening folding process is completed, the folding mechanism 2 is driven by the first driving mechanism 12 to return to the initial position along the Y axis, that is, withdrawn from above the material fixing mechanism 3.

[0044] In this way, after the bag opening cloth piece is cut, the folding process of the bag mouth is completed in the process of going to the accessory loading station. Compared with the prior art, it not only shortens the processing time, but also shortens the moving distance of the device, so that the length of the working table of the bag opening machine can be shortened.

[0045] The folding pressing piece 36 has a fixing and maintaining function for the shape of the bag mouth after the folding bag is processed. Compared with the shaping pressing block in the prior art, it has a simple structure and a good fixing and maintaining effect, which greatly reduces the unqualified rate of finished products.

[0046] 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.
