DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] The woven bag production bottom sewing device provides two technical solutions:

[0028] like Figure 1-4 The first embodiment is shown: it includes a first conveying mechanism 1, a second conveying mechanism 2, a bag pressing assembly 3 and a sewing mechanism 4. A feeding mechanism is arranged above the second conveying mechanism 2. The second conveying mechanism 2 is composed of a workbench and two front and rear belt conveying assemblies, and the conveying belt in the belt conveying assembly passes over the top of the workbench. The feeding mechanism includes:

[0029] The one-by-one feeding component 5 is arranged above the second conveying mechanism 2, and is used to realize the one-by-one feeding of the woven bags. The one-by-one feeding component 5 includes two left and right baffles 51. A spline shaft 52 is rotatably connected between the left and right sides of the inner walls of the two baffles 51. A bottom plate 53 is slidably installed on the surfaces of the two spline shafts 52. The two spline shafts 52 penetrate the baffles 51 and extend to one end of the right side of the baffle 51. A rocker rod 54 is fixedly connected, and a guide groove 55 is provided inside the rocker rod 54. The right sides of the two baffles 51 are fixedly connected to a support plate 56, and the top of the support plate 56 is fixedly connected to a drive motor 57. The output end of the drive motor 57 is fixedly connected to a disc 58, and the left sides of the two discs 58 are fixedly connected to guide rods 59. The front and rear guide rods 59 are respectively located in the two guide grooves 55.

[0030] The stabilizing component 6 is arranged above the two bottom plates 53 on the same side, and is used to adjust the distance between the two bottom plates 53. The stabilizing component 6 includes a hydraulic cylinder 61, which is fixedly connected to the bottom of the inner wall of the second conveying mechanism 2, and the output end of the hydraulic cylinder 61 extends to the top of the second conveying mechanism 2. The telescopic end of the hydraulic cylinder 61 located above the second conveying mechanism 2 is fixedly connected to a top plate 62.

[0031] When the woven bags are loaded with sewing materials, the woven bags are loaded one by one through the cooperation of the loading assembly 5 and the stabilizing assembly 6, so that the woven bags can be loaded quickly, thereby improving the working efficiency of the device.

[0032] like Figure 4 and 5 The second embodiment is shown, and the main difference from the first embodiment is that an adjustment component 7 is arranged above the left and right base plates 53, and the adjustment component 7 is used to adjust the distance between the left and right base plates 53. The adjustment component 7 includes left and right connecting blocks 71, and the two connecting blocks 71 are respectively fixedly connected to the tops of the left and right base plates 53. A bidirectional threaded rod 72 is rotatably connected between the two connecting blocks 71, and a handle 73 is fixedly connected to one end of the bidirectional threaded rod 72 located on the right side of the right connecting block 71.

[0033] The left and right bottom plates 54 in the one-by-one feeding assembly 5 can be adapted to woven bags of different widths by adjusting the distance between the two bottom plates 53 through the adjustment assembly 7, thereby improving the applicability of the device when in use.

[0034] When in use, according to the width of the weaving, the bidirectional threaded rod 72 is rotated by turning the handle 73, and the bidirectional threaded rod 72 rotates and drives the two bottom plates 53 to move closer or farther from each other through the connecting block 71, so as to adapt to the width of the woven bag. Then, the stacked woven bags are placed on top of the four bottom plates 53, and the hydraulic cylinder 61 is started to make the top plate 62 contact with the bottom of the woven bag. When loading is required, the front drive motor 57 is started first to make the disc 58 rotate, and the disc 58 rotates and drives the guide rod 59 to rotate. Under the cooperation of the guide rod 59 and the guide groove 55, the swing rod 54 is rotated, and then the bottom plates 53 are driven through the spline shaft 52. The plate 53 rotates, and after the bottom plate 53 rotates to a certain angle, one side of the woven bag loses support and falls under the action of gravity. The left disc 58 continues to rotate and causes the bottom plate 53 to start to rotate back. At this time, the rear drive motor 57 starts to break the grid, and the other side of the woven bag falls in the same way. At this time, both sides of the bottom woven bag are detached from the bottom plate 53 and are below the bottom plate 53. After the front and rear bottom plates 53 return to their original positions, the hydraulic cylinder 61 is started to move the top plate 62 downward, so that the woven bag contacts the output belt in the second conveying mechanism 2, and is sent into the first conveying mechanism 1 for bottom sewing.
