The worktable 1 is provided with a fixing mechanism 2 for pressing and positioning the fabric and a pressing mechanism 3 for pressing down the folded edge of the fabric. The worktable 1 is provided with a folding mechanism 4 for turning over the folded edge of the fabric.

[0031] like Figure 4 As shown, the material positioning mechanism 2 includes an L-shaped tray 21, a material feeding mechanism 22 for placing the fabric, a material pressing mechanism 23 for pressing and positioning the fabric, and a clamping mechanism 24 for clamping the folded edges of the fabric.

[0032] like Figure 2As shown, the pressing mechanism 3 includes a mounting frame 31, a third drive mechanism, a fixed frame 33, and a pressing head 34. The third drive mechanism is mounted on the mounting frame 31, and a gear 35 is provided on the drive end of the third drive mechanism. A rack 36 is provided on the fixed frame 33. The gear 35 and the rack 36 mesh. The fixed frame 33 and the mounting frame 31 slide in the Z-axis direction. The pressing head 34 is mounted on the bottom end of the fixed frame 33.

A plurality of shaping teeth 38 for pressing down the folded edge of the fabric are arranged sequentially between the positioning teeth 37. Positioning grooves 39 are provided between adjacent shaping teeth 38.

[0033] Specifically, the fabric is placed on the cover plate 211 of the feeding mechanism 22, the pressing mechanism 23 positions and presses the fabric, the laser mechanism cuts the fabric open, the two third cylinders 242 of the clamping mechanism 24 drive the clamping plate 241 to move downward, so that the clamping plate 241 is separated from the support plate by a certain distance, and then the third drive mechanism of the pressing mechanism 3 drives the gear 35 to rotate, the gear 35 drives the rack 36 to move downward, the rack 36 drives the fixing frame 33 and the pressing head 34 to move downward to press down the folded edge of the fabric, the two first folding components 43 of the folding mechanism 4 approach each other, and the two second folding components 44 approach each other on the two sides of the two first folding components 43 respectively, the lifting mechanism 42 drives the support base 41 to drive the multiple first folding teeth 433 and the multiple second folding teeth 445 of the two first folding plates 432 to pass through the multiple first teeth of the clamping plate 241. The first folding teeth 433 of the two first folding components 44 drive the two long folded edges of the fabric on the side of the lower pressure head 34 to move in opposite directions, so that the two long folded edges of the fabric are located below the support plate. The second folding teeth 445 of the two second folding components 44 drive the two short folded edges of the fabric on the side of the lower pressure head 34 to move in opposite directions, so that the two short folded edges of the fabric are located below the support plate. The two third cylinders 242 of the clamping mechanism 24 drive the clamping plate 241 to move towards the support plate to clamp the four folded edges of the fabric. The lifting mechanism 42 drives the support base 41 to move the first folding components 43 and the second folding components 44 downward, so that the first folding teeth 433 and the second folding teeth 445 pass through the first teeth 244 and the second teeth 245 of the clamping plate 241 and disengage from the support plate.

[0034] In the above structure, the positioning mechanism 2, pressing mechanism 3, and folding mechanism 4 work together to achieve the positioning, pressing, folding, and clamping operations of the fabric. The pressing mechanism 3 uses multiple shaping teeth 38 to facilitate pressing down on the fabric, multiple positioning grooves 39 to match the multiple first folding teeth 433 of the two first folding components 43, and positioning tooth openings 37 to match the second folding teeth 445, thus achieving the folding of the fabric. This pressing and folding mechanism of the bag opening machine not only improves the accuracy of folding but also enhances its versatility, making it applicable to fabrics of various materials and greatly improving the folding efficiency of the equipment.

In the initial state, the two first folding assemblies 43 are abutting against each other, and the two second folding assemblies 44 are located at the two ends of the two first folding assemblies 43. When the pressing mechanism 3 presses down on the four folds of the fabric, the lifting mechanism 42 drives the support base 41 to move the two first folding components 43 and the two second folding components 44 upward, so that the multiple first folding teeth 433 of the two first folding components 43 extend into the multiple positioning grooves 39 of the pressing head 34, and the multiple second folding teeth of the two second folding components 44 extend into the positioning tooth openings 37 of the pressing head 34. Then, the two first folding components 43 move in opposite directions, and the two second folding components... The components 44 move in opposite directions. The first drive mechanism 431 of the first folding assembly 43 drives the first folding plate 432 to drive multiple first folding teeth 433 to fold the long folded edge fabric on the side of the pressing head 34 downwards onto the support plate. The second drive mechanism 442 of the second folding assembly 44 drives the second folding plate 443 to drive multiple second folding teeth 445 to fold the short folded edge fabric on the side of the pressing head 34 downwards onto the support plate. After the four folded edges of the fabric are folded, the clamping mechanism 24 clamps the four folded edges.

The first cylinder 100 drives the first connecting plate 102 to adjust the position of the long insert knife 101, which is located between the cover plate 211 and the bottom plate 212. The first cylinder 100 drives the first connecting plate 102 to move the long insert knife 101 horizontally to adjust the size of the rectangular slot, thereby adjusting the size of the fabric pocket opening and improving versatility. The use of the first cylinder 100 improves the moving efficiency of the long insert knife 101, thereby improving the adjustment efficiency of the equipment. The long insert 101 can be connected to the top of the first connecting plate 102 by a bolt assembly or by snap-fitting with the first connecting plate 102, allowing for quick replacement of the long insert 101.

The short insert 103 is detachably connected to the middle end of the second connecting plate 105. The two second cylinders 104 drive the second connecting plate 105 to adjust the position of the short insert 103, which is located between the cover plate 211 and the bottom plate 212. The two second cylinders 104 simultaneously drive the second connecting plate 105 to move the short insert 103 horizontally to adjust the size of the rectangular slot, thereby adjusting the size of the fabric pocket opening and improving versatility. The use of two second cylinders 104 improves the moving efficiency of the short insert 103, thereby improving the adjustment efficiency of the equipment. The short inserter 103 can be connected to the top of the second connecting plate 105 by a bolt assembly or by snap-fitting with the second connecting plate 105, allowing for quick replacement of the short inserter 103.

The clamping plate 241 is located below the L-shaped support plate 21. The two third cylinders 242 are used to drive the clamping plate 241 to move up and down below the L-shaped support plate 21. The clamping plate 241 is provided with a rectangular opening 243 for cooperating with the folding mechanism 4. Several first teeth 244 are arranged at intervals on the two long ends of the rectangular opening 243, and several second teeth 245 are arranged at intervals on the two short ends of the rectangular opening 243. The first teeth 244 are adapted to the first folding teeth 433, and the second teeth 245 are adapted to the second folding teeth 445. When the two third cylinders 242 drive the clamping plate 241 to move in the opposite direction to the support plate, the first folding assembly 43 and the second folding assembly 44 fold the fabric edges under the support plate. When the two third cylinders 242 drive the clamping plate 241 to move towards the support plate, the clamping plate 241 clamps the fabric edges. The first folding tooth 433 of the first folding assembly 43 and the second folding tooth 445 of the second folding assembly 44 can pass through the first tooth opening 244 and the second tooth opening 245 respectively to disengage from the support plate.
