[0001] The utility model relates to the technical field of clothing bag opening equipment, in particular to a bag opening folding and shaping device and a clothing bag opening and folding machine. Background Art

[0002] Folding is one of the necessary steps in forming clothing pockets. At present, the general process of opening clothing pockets is: first open the seam by laser, then use the bag folding mechanism to move the folded edge of the bag mouth around, and finally shape the folded edge. Existing bag folding mechanisms, such as the Chinese utility model patent application with authorization announcement number CN212955653U, record an improved structure of an automatic bag folding device for opening cloth bags. Although this bag folding device can adjust the size of the slot and use different lengths of bag mouths, the width direction of the downward pressing and opening mold cannot be adjusted, especially it is difficult to meet the processing requirements of narrow bag mouths. Summary of the invention

[0003] In view of the above-mentioned shortcomings of the prior art, the purpose of the utility model is to provide a bag mouth folding and shaping device and a clothing bag opening and folding machine, which are used to solve the problem that the width of the bag folding device in the prior art cannot be adjusted and cannot meet the processing requirements of narrow bag mouths.

[0004] In order to achieve the above purpose and other related purposes, the utility model provides the following technical solutions:

[0005] The first aspect of the disclosed embodiment of the utility model provides a bag mouth folding and shaping device, comprising:

[0006] A support and shaping mechanism for placing and pressing the pieces to be processed, the support and shaping mechanism comprising: a support plate for supporting the pieces to be processed, and elastic pressing components arranged on both sides of the support plate for pressing the pieces to be processed, and a notch for bag folding operation is formed in the middle of the support plate;

[0007] A downward pressure bag-holding mechanism is arranged above the supporting and shaping mechanism and is used to hold the bag opening open. The downward pressure bag-holding mechanism comprises: a bag-holding mold that can be lifted and lowered, a core mold adjustment block that is detachably connected to both sides of the bag-holding mold along the length direction and is used to hold the bag opening open, and an external pressure baffle that is slidably and adjustably connected to both sides of the bag-holding mold along the width direction and is used to press the edge of the bag opening tightly;

After the folding plate rises into place, the two folding plates are driven away from each other by the material-pickup driving mechanism. During the movement of the folding plate, the material-pickup teeth can further fold and press the bag opening outward to achieve the purpose of folding the bag. Since the core mold adjustment block is detachable and replaceable and the external pressure baffle is adjustable, it can adapt to the bag-supporting needs of pockets of different sizes. Since the material-pickup teeth can be engaged with each other, they can be closed into a narrower width at the beginning of folding, thereby being able to adapt to the folding processing of bag openings with a larger width specification range, especially the folding needs of pockets with narrower widths, without the need to replace folding plates of different sizes, saving replacement time and cost.

[0025] To implement the above technical solution, before opening the bag, the size of the notch can be controlled by driving the adjusting driving member to drive the shaping sheet to move to a suitable position, thereby adapting to the processing of bag openings of different specifications and sizes.

[0026] As a preferred solution of the utility model, the movable seat comprises:

[0027] Folding edge fixing seat;

[0028] a hem-folding sliding seat slidably mounted on the hem-folding fixing seat in a vertical direction, the hem-folding plate slidably mounted on the hem-folding sliding seat; and,

The transmission assembly 332 is used to drive the double helical screw to rotate. A screw seat 334 is fixed to the bottom of the sliding base 322. The screw seat 334 is threadedly connected to the double helical screw 333. The thread directions of the two screw seats 334 corresponding to the two hemming plates 32 are opposite, so that when the double helical screw 333 rotates, the hemming plates 32 can be driven to move closer or farther away from each other. The transmission component 332 can adopt a belt component or a gear component. In the present embodiment, a belt component is adopted, specifically: a driving pulley is fixed on the power output shaft of the material-discharging motor 331, and a driven pulley is fixed on one end of the double helical screw rod 333 passing 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 double helical screw rod 333 through the transmission component 332 to drive the double helical screw rod 333 to rotate. The forward and reverse rotation of the material-discharging motor 331 can drive the two folding plates 32 to be relatively close to or away from each other.

[0068] 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. The supporting sheet 142 is provided with supporting teeth 143 on the side close to the folding plate 32. The supporting teeth 143 and the corresponding 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.

[0069] 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.

[0070] When processing the bag opening, first install the core mold adjustment block 22 of the corresponding size according to the size of the bag opening to be processed, and adjust the external pressure baffle 23 to a suitable position, and drive the shaping piece 132 to a suitable position by adjusting the driving member 131, then place the cut pieces to be processed on the supporting plate 11, and press the cut pieces to be processed relatively tightly by the elastic pressing component 12 to prevent displacement during the processing, and then open the pocket at the notch 111 by laser cutting;

[0071] After the opening is completed, 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 against the edge of the bag opening, and then the bag-opening 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, so as to open the bag opening around and complete the bag-opening process. At this time, the edge of the bag opening is pressed down into the notch 111;

[0072] The folding drive mechanism 313 then drives the folding sliding seat 312 to drive the folding plate 32 to rise until the support piece 314 contacts the movable mold core 214, and lifts 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. In the initial state, the material-pickup teeth 321 of the two folding plates 32 are in a relatively engaged state, so as to meet the processing requirements of a narrower width pocket. After the support piece 314 and the folding plate 32 rise to the right position, the material-pickup drive mechanism 33 drives the two folding plates 32 to move away from each other. During the movement of the folding plate 32, the material-pickup teeth 321 can further fold the bag mouth part outward, thereby achieving the purpose of folding the bag.

[0073] Then, the material supporting driving member 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 member 215 drives the movable mold core 214 to rise and reset. The movable mold driving member 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 plates 32 to move closer to each other and reset. After the folding action is completed, subsequent sewing can be carried out.

[0074] Since the core mold adjustment block 22 is detachable and replaceable and the external pressure baffle plate 23 is adjustable, it can adapt to the bag-supporting requirements of bags of different sizes. Since the material-selecting teeth 321 can be inserted into each other, they can be closed to a narrower width at the beginning of folding, thereby being able to adapt to the folding processing of bag mouths with a larger width specification range, especially the folding requirements of pockets of narrower width, without the need to replace folding plates 32 of different sizes, saving replacement time and cost.

[0075] 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 pressing bag supporting mechanism 20 and a material shifting and folding mechanism 30 are fixed to the work surface or the frame.

Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
