DETAILED DESCRIPTION
[0020] The utility model embodiment provides a new type of pressing frame assembly of a fully automatic bag opening machine, such as Figure 1-3 As shown, it is a component on the workbench of the bag opening machine that moves horizontally between the workstations. The conventional bag opening machine workbench is horizontally provided with three workstations, namely, a laser cutting mechanism, a sewing mechanism and a knife inserting mechanism. The specific structure of the above bag opening machine is not repeated here, and all are prior art. The substrate 1 drives the cloth to move on the workbench through the horizontal movement mechanism.
[0021] like Figure 1 As shown, the innovation of the device is to improve the structure on the existing substrate 1, including the substrate 1 and the material fixing mechanism and the material pulling mechanism arranged on the substrate 1. The material fixing mechanism and the material pulling mechanism are arranged up and down in the front view, and the two mechanisms do not interfere with each other when running in a plane. The material fixing mechanism is located above the material pulling mechanism. A shaping groove 24 is arranged at the center of the substrate 1, and the blades on the material fixing mechanism and the material pulling mechanism correspond to the four sides of the shaping groove 24.
[0022] The material-fixing mechanism comprises two groups of front and rear material-fixing knives 2, left and right material-fixing knives 3 and a driving component. The two groups of front and rear material-fixing knives 2, left and right material-fixing knives 3 are arranged on the four sides of the shaping groove 24 in a front-back and left-right manner.
[0023] like Figure 2 As shown, the driving components include a cylinder 4, a front and rear connecting plate 5, a left and right connecting plate 7, and a linkage plate 8. The cylinder 4 is fixed on the base plate 1 and its output end is connected to the front and rear connecting plates 5 through a driving rod 6. The cylinder 4 is arranged longitudinally. Four cylinders 4 can be provided, and two of the front and rear connecting plates 5 are driven to move longitudinally. The front and rear sizing knives 2 and the front and rear connecting plates 5 are provided with matching connecting screw holes 11. The front and rear sizing knives 2 are detachably connected to the front and rear connecting plates 5 through the connecting screw holes 11, and the connecting screw holes 11 between the two are connected by bolts. The left and right sizing knives 3 and the left and right connecting plates 7 are provided with matching connecting screw holes 11. The left and right sizing knives 3 are detachably connected to the left and right connecting plates 7 through the connecting screw holes 11, and the connecting screw holes 11 between the two are connected by bolts. The base plate 1 is provided with a slide groove for the left and right connecting plates 7 to slide horizontally. The linkage plate 8 is fixed on the front and rear connecting plates 5. The linkage plate 8 is provided with a 45° inclined guide groove 9. The left and right connecting plates 7 are provided with a guide shaft 10 that is slidably adapted in the guide groove 9.
[0024] The principle of the material fixing mechanism is that when the cylinder 4 drives the front and rear connecting plates 5 to move longitudinally, the front and rear connecting plates 5 are guided by the linkage plate 8 to cause the left and right connecting plates 7 to move laterally, thereby realizing the linkage of the front and rear material fixing knives 2 and the left and right material fixing knives 3.
[0025] like Figure 3 As shown, the material pulling mechanism includes two groups of left and right material pulling knives 15, a lead screw slide rail module 1 16, a straight connecting rod 17, a bent connecting rod 18, a guide rail 19, a slider 20, front and rear material pulling knives 21, a lead screw slide rail module 2 22, and a mounting plate 23. The lead screw slide rail module 1 16 and the lead screw slide rail module 2 22 are both existing commercially available lead screw slide rail modules, which are composed of lead screws, slide rods, nuts, motors and other components, and are used to replace traditional cylinders. Its movement is more precise than that of cylinders. The lead screw slide rail module 2 22 is longitudinally arranged on the base plate 1 and connected to the mounting plate 23. The front and rear material pulling knives 21 and the mounting plate 23 are both provided with matching connecting screw holes 11. The connecting screw holes 11 of the two are fixedly connected by bolts. The front and rear material pulling knives 21 are detachably connected to the mounting plate 23 through the connecting screw holes 11. The base plate 1 is provided with a slide groove for the longitudinal sliding of the straight-connecting rod 17, and the width of the slide groove is greater than the width of the straight-connecting rod 17, so that the straight-connecting rod 17 has a certain lateral swing when moving longitudinally. The screw slide rail module 16 is longitudinally arranged on the base plate 1 and its movable nut is connected to the straight-connecting rod 17, the guide rail 19 is transversely arranged on the base plate 1, and the slider 20 is slidably adapted on the guide rail 19. The two ends of the bent connecting rod 18 are respectively hinged to the straight-connecting rod 17 and the slider 20, and the left and right pulling knives 15 and the slider 20 are provided with matching connecting screw holes 11, and the connecting screw holes 11 of the two are fixedly connected by bolts, and the left and right pulling knives 15 are detachably connected to the slider 20 through the connecting screw holes 11.
[0026] The principle of the pulling mechanism: the two front and rear pulling knives 21 are relatively controlled in their longitudinal movement by two sets of screw slide rail modules 22, and the two left and right pulling knives 15 are respectively driven by two screw slide rail modules 16. The screw slide rail module 16 drives the straight connecting rod 17 to move longitudinally, and the straight connecting rod 17 drives the slider 20 to move horizontally through the bending connecting rod 18, thereby driving the two left and right pulling knives 15 to move horizontally.
[0027] In order to limit the upward movement of the sizing knife and the pulling knife, the front and rear sizing knives 2 and the left and right sizing knives 3 are at the top of all components, and a fixing plate 12 covering the front and rear sizing knives 2 and the left and right sizing knives 3 is provided on the base plate 1. There is a slight gap between the fixing plate 12 and the front and rear sizing knives 2 and the left and right sizing knives 3, and the fixing plate 12 does not affect the displacement of the front and rear sizing knives 2 and the left and right sizing knives 3.
[0028] In order to limit the telescopic distance of the front and rear sizing knives 2 and the left and right sizing knives 3 each time, a limiting slide groove 13 for limiting the movable distance of the driving rod 6 is provided on the fixed plate 12. The length of the limiting slide groove 13 is determined according to the required moving distance and the limit point.
[0029] The fixing plate 12 is also provided with a limiting slide groove 14 for limiting the movable distance of the bolts on the connecting screw hole 11. The length of the limiting slide groove 14 is determined according to the required moving distance and the limiting point.
[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
