[0002] In the prior art, bag opening machines have been widely used. A Chinese utility model with a publication number of CN220619362U discloses a pressing frame component on a garment processing device, comprising a pressing frame body with a pressing window opened transversely at the front end, the pressing window being rectangular, and the four lower edges of the pressing window being provided with flanges extending vertically downward, at least one flange on the front and rear long sides of the pressing window being adjustable along the front-to-back direction and fixed at different positions, and the flanges on the front and rear short sides of the pressing window being adjustable along the left-to-right direction and fixed at different positions, so that the size of the processing window enclosed by the flanges is adjustable.

[0003] This technical solution uses flanges to press the fabric, and uses flanges installed at different positions of the press frame to adjust the processing window; compared with the prior art, one bag opening machine can meet the processing of various bag openings within a certain size range. However, its adjustment range is too narrow, and in this technical solution, the flanges on the four sides are pressed down at the same time as the press frame. After the fabric is pressed by the flanges, the fabric is not flat and a bulge appears in the middle. This defect is difficult to solve by this technical solution. Utility Model Content

[0005] To achieve the above purpose, the technical solution of the utility model is:

[0006] A pressing frame for a material fixing device of a bag opening machine comprises a pressing frame body, on which an outer pressing frame, an inner pressing plate and an inner pressing plate lifting mechanism for driving the inner pressing plate to lift relative to the outer pressing frame are arranged; the outer edge of the inner pressing plate and the bottom edge of the outer pressing frame and two side edges of the outer pressing frame form a processing window; a first pressing plate bent downward is arranged at the bottom edge of the outer pressing frame, and a second pressing plate bent downward is arranged at the outer edge of the inner pressing plate.

[0007] The inner pressure plate lifting mechanism is arranged on the pressure frame body, the inner pressure plate lifting mechanism is provided with a mounting plate, and the inner pressure plate is connected with the mounting plate.

[0008] The mounting plate is symmetrically provided with longitudinally long first mounting holes or slots, and the inner pressure plate is adjustably arranged on the mounting plate through the first mounting holes or slots.

[0009] Longitudinally long second mounting holes or slots are longitudinally symmetrically arranged on both sides of the inner pressure plate, and the second pressing plate is adjustably mounted on the bottom of the inner pressure plate through the second mounting holes or slots.

[0010] The bottom of the first pressing plate and the bottom of the second pressing plate are both configured to be sawtooth-shaped.

[0011] Two or more adjustment holes are respectively arranged on both sides of the first pressing plate, and an adjustment block is respectively arranged on both sides of the first pressing plate. The adjustment block is adjustably mounted on the first pressing plate through the adjustment holes.

[0012] The inner pressure plate lifting mechanism is a cylinder.

[0013] The advantages of the utility model are as follows: 1. The utility model can adjust the width of the processing window in two levels. In the first level of adjustment, the first mounting hole or slot of the mounting plate allows the inner pressure plate to move inwards and outwards to adjust the width of the second processing window to meet the product processing requirements; in the second level of adjustment, the second mounting hole or slot of the inner pressure plate allows the second pressure plate to be adjusted and installed inwards and outwards on the inner pressure plate, which can further adjust the width of the second processing window to meet the processing requirements of more products. 2. The adjustment block set on the first pressure plate can adjust the length of the processing window; 3. The bottom of the first pressure plate and the second pressure plate is serrated, which increases the friction between the pressure part and the cloth, and further ensures the stable clamping of the cloth; 4. The pressing frame presses the cloth, and the outer pressure frame descends to drive the first pressure plate to press the cloth first, and then the inner pressure plate descends, driving the second pressure plate to press the cloth downward, eliminating the phenomenon of uneven pressing of the cloth and bulging in the middle.

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 pressing frame for a material setting device of a bag opening machine, such as Figure 1 , Figure 2 As shown, it has a pressing frame body 1, on which an outer pressing frame 2, an inner pressing plate 3 and an inner pressing plate lifting mechanism 4 for driving the inner pressing plate 3 to rise and fall relative to the outer pressing frame 2 are arranged, the outer edge of the inner pressing plate 3 and the bottom edge of the outer pressing frame 2 and the two side edges of the outer pressing frame 2 form a processing window 6, a first pressing plate 21 bent downward is arranged at the bottom edge of the outer pressing frame 2, and a second pressing plate 31 bent downward is arranged at the outer edge of the inner pressing plate 3.

[0021] Preferably, if Figure 2 As shown, in order to increase the friction between the first pressing plate 21 and the second pressing plate 31, the bottom of the first pressing plate 21 and the bottom of the second pressing plate 31 are both configured to be serrated.

[0022] The utility model can adjust the processing window 6 in two levels, such as Figure 1 As shown, in the first stage of adjustment, longitudinal long strip first mounting holes 51 or grooves are symmetrically arranged on the mounting plate 5, and the inner pressure plate 3 is fixed to different positions inside and outside the first mounting hole 51 or groove by bolts and other fixing parts, so that the mounting plate 5 can be adjusted inside and outside, and the width of the processing window 6 can be adjusted. In the second stage of adjustment, longitudinal long strip second mounting holes 32 or grooves are symmetrically arranged on both sides of the inner pressure plate 3, and the second pressure plate 31 is fixed to different positions inside and outside the second mounting hole 32 or groove by bolts and other fixing parts, so that the mounting plate 3 can be adjusted inside and outside, and the width of the processing window 6 can be further adjusted.

[0023] like Figure 2 , Figure 3 As shown, a device for adjusting the length of the processing window 6 is also provided. Two or more adjustment holes 22 are provided on both sides of the first pressing plate 21. An adjustment block 23 is provided on both sides of the first pressing plate 21. According to the needs of different product parameters, the adjustment block 23 can be selectively provided in different adjustment holes 22, thereby realizing the adjustable length of the processing window 6.
