[0068] The material dispensing driving mechanism 33 includes: a material dispensing motor 331 fixed to the hemming sliding seat 312, a transmission assembly 332 connected to the power output shaft of the material dispensing motor 331, and a driving screw 333 rotatably assembled on the hemming sliding seat 312, the transmission assembly 332 is used to drive the driving screw 333 to rotate, a screw seat 334 is fixed at the bottom of the sliding base 322, and the screw seat 334 is threadedly connected to the driving screw 333; the transmission assembly 332 can adopt a belt assembly or a gear assembly, and the present invention A belt assembly is used in the embodiment, specifically: a driving pulley is fixed on the power output shaft of the material discharging motor 331, and a driven pulley is fixed to one end of the driving screw 333 that passes through the folding sliding seat 312, and a transmission belt is sleeved between the driving pulley and the driven pulley. When the material discharging motor 331 is actuated, the power can be transmitted to the driving screw 333 through the transmission assembly 332, driving the driving screw 333 to rotate, and the material discharging motor 331 can drive the two folding plates 32 to be relatively close to or away from each other by forward and reverse rotation.

[0069] Further, such as Figure 2 and Figure 3 As shown, the supporting plate 11 is also provided with a supporting assembly 14 for supporting the edge of the bag mouth after the bag is folded. The supporting assembly 14 is arranged corresponding to the two folding plates 32, including: a supporting driving member 141 fixed to the supporting plate 11, and a supporting sheet 142 connected to the power output shaft of the supporting driving member 141, a supporting tooth 143 is provided on the side of the supporting sheet 142 close to the folding plate 32, and a material shifting tooth 321 is provided on the upper end of the folding plate 32. The supporting teeth 143 and the material shifting teeth 321 are staggered and can be inserted into each other. The supporting driving member 141 adopts a small cylinder. Usually, a connecting plate 144 is also provided between the supporting driving member 141 and the supporting sheet 142 to realize the installation and fixation of the supporting sheet 142. The connection method of the connecting plate 144 and the supporting driving member 141 is the same as the connection method of the adjusting driving member 131 and the shaping sheet 132, which will not be repeated here.

[0070] When the folding plate 32 completes the folding action, the supporting piece 142 is driven by the supporting driving member 141 to move to the supporting tooth 143 and the material-pickup tooth 321 to be inserted, and then the folding sliding seat 312 is driven to descend by the folding driving mechanism 313. At this time, the edge of the bag mouth after folding can be shaped by the supporting piece 142 and the supporting tooth 143, and because the supporting tooth 143 and the material-pickup tooth 321 are staggered, the two will not interfere with each other.

[0071] When processing the bag opening, first adjust the outer pressure baffle 23 to a suitable position according to the size of the bag opening to be processed, place the cut piece 50 to be processed on the support plate 11, and relatively press the cut piece 50 to be processed by the elastic pressing component 12 to prevent displacement during processing, and then press the pressing frame 41 downward to make the pressure strip plate 42 press the position near the folding line 51 to prevent the sewing position from being fixed not firmly enough due to the distance being too far and simply relying on the elastic pressing component 12 to press the cut piece 50;

[0072] Then, the movable mold driving member 213 drives the movable mold fixing seat 212 to drive the movable mold core 214 and the external pressure baffle 23 to descend until the external pressure baffle 23 is pressed tightly at the folding line 51, and then the bag supporting driving member 215 drives the movable mold core 214 and the core mold adjusting block 22 to continue to descend and embed into the notch 111, and the outer side of the cut piece 50 is folded downward along the folding line 51, completing the initial bag folding process. At this time, the edge of the bag mouth is pressed down into the notch 111;

[0073] Then, the folding driving mechanism 313 drives the folding sliding seat 312 to drive the folding plate 32 to rise until the supporting piece 314 contacts the movable mold core 214, and pushes the movable mold core 214 upward for a distance, so that the folding plate 32 is located in the notch 111 and can move the edge of the bag mouth. After the supporting piece 314 and the folding plate 32 rise to the right position, the folding plate 32 is driven to move by the material shifting driving mechanism 33. During the movement of the folding plate 32, the material shifting teeth 321 can further fold the bag mouth part outward, thereby achieving the purpose of folding the bag.

[0074] Then, the material supporting driving component 141 drives the material supporting sheet 142 to move toward the folding plate 32 until the material supporting tooth 143 is engaged with the material shifting tooth 321. At this time, the material shifting tooth 321 is partially located at the bottom of the edge of the bag opening to support and shape the folding part. The bag supporting driving component 215 drives the movable mold core 214 to rise and reset. The movable mold driving component 213 drives the movable mold fixing seat 212 to rise and reset. The folding driving mechanism 313 drives the folding sliding seat 312 to descend and reset. The material shifting driving mechanism 33 drives the folding plate 32 to reset. After the folding action is completed, the subsequent sewing process can be carried out.

[0075] Since the external pressure baffle 23 is adjustable, it can adapt to the bag folding requirements of pockets of different sizes without replacing the folding plates 32 of different sizes, saving replacement time and cost. Through the cooperation of the material supporting and shaping mechanism 10, the downward pressure bag supporting mechanism 20, the auxiliary material pressing mechanism 40 and the material shifting and folding mechanism 30, the automatic bag folding processing of the original bag is realized, thereby improving the processing efficiency.

[0076] The second aspect of the embodiment of the utility model provides a clothing bag opening and folding machine, including: the bag mouth folding and shaping device as described in the first aspect. It can be understood that the clothing bag opening and folding machine has a frame, a work surface is fixed on the frame, a material supporting and shaping mechanism 10 is fixed to the work surface, and a downward pressure bag supporting mechanism 20, an auxiliary material pressing mechanism 40 and a material shifting and folding mechanism 30 are fixed to the work surface or the frame.

[0077] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. All equivalent modifications or changes made by those skilled in the art without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
