[0025] See also Figures 1 to 6 , a woven bag loom, comprising a frame 1, a column 12, a crossbeam 13, a bobbin rack 2, a textile part, a reed power device, a rotating plate 9 and a shuttle thread drum 10, wherein a linear array of bobbins 21 is arranged on the bobbin rack 2, and the textile part comprises a first weaving shaft 3, a second weaving shaft 4, a first reed 5, a second reed 6 and a rotating plate 9, wherein the first weaving shaft 3 is rotatably connected to the bottom of the frame 1 near the bobbin rack 2, and the second weaving shaft 4 is rotatably connected to the top of the frame 1 near the bobbin rack 2, the first reed 5 and the second reed 6 are slidably connected to the column 12 of the frame 1 and driven by the reed power device, the rotating plate 9 is rotatably connected to the frame 1, and a side plate 93 is installed on the side of the rotating plate 9 on the frame 1, and a shuttle thread drum 10 is rotatably connected to the side plate 93, and a shuttle thread drum 101 is arranged in a circular array on the shuttle thread drum 10.
[0026] like Figure 3 and Figure 4 As shown, the reed power device includes a first cross bar 7, a traction rod 71, a second cross bar 8 and an eccentric wheel group 81. The height of the second cross bar 8 is slightly higher than that of the first cross bar 7. The first cross bar 7 and the second cross bar 8 are rotatably mounted on the frame 1. The first cross bar 7 is rotatably connected to two traction rods 71, and the two traction rods 71 are respectively connected to the first reed 5 and the second reed 6. The second cross bar 8 is equipped with an eccentric wheel group 81.
[0027] like Figure 3 and Figure 4 As shown, the eccentric wheel group 81 is composed of two eccentric wheels, the protrusions of the two eccentric wheels are in opposite directions, and the end of the first cross bar 7 is connected to the first reducer 82.
[0028] The column 12 is provided with a spring inside to ensure that the first leaf spring 5 and the second leaf spring 6 are always subjected to an upward elastic force when they are not subjected to the pulling force of the traction rod 71 .
[0029] The beam 13 is provided with a light sensor receiver 11 .
[0030] like Figure 2 and Figure 4 As shown, the rotating plate 9 is driven by a power device, which includes two connecting rods 91 and a second reducer 92. One end of the two connecting rods 91 is connected to the rotating plate 9, and the other end is connected to the output end of the second reducer 92. The second reducer 92 is installed on the side plate 93.
[0031] Principle and operation process
[0032] The utility model adopts a controller with a single chip microcomputer as the core to control each component. Before the equipment is started, the threading operation is first completed, and the braiding line is installed on the bobbin 21 and the shuttle bobbin 101, and the equipment is started. The first reducer 82 starts to work, driving the second cross bar 8 to rotate, and the eccentric wheel group 81 on the second cross bar 8 rotates accordingly. The two eccentric wheels of the eccentric wheel group 81 alternately press down the two traction rods 71, thereby realizing the up and down alternating movement of the first reed 5 and the second reed 6. After the shuttle is threaded, the second reducer 92 starts to work, driving the end of the second connecting rod 91 connected to the output shaft of the second reducer 92 to start rotating, and the end of the second connecting rod 91 connected to the rotating plate 9 can realize reciprocating motion, driving the rotating plate 9 to move back and forth, and the controller controls the rotation speed of the first reducer 82 and the second reducer 92, so that the two reducers can cooperate to realize the first reed 5 and the second reed 6 alternating once, the shuttle is threaded once, and the rotating plate 9 completes pushing and pulling once, thereby completing the weaving action.
[0033] The light receiving sensor 11 arranged on the crossbeam 13 can detect whether the thread passing through the second weaving shaft 4 is broken. If the thread is broken, the controller will control the equipment to suspend operation and complete the thread change. When changing the thread, since more bobbins 21 than the number of lead wires are arranged on the bobbin rack 2, the threads can be connected in series in groups of 2 or 3. When it is inconvenient to connect in series, the thread of the second bobbin 21 can be connected immediately after the first bobbin 21 is used up, which saves the operation of replacing the thread reel and speeds up production efficiency. After the shuttle thread reel is used up, the shuttle thread disk 10 is rotated to quickly connect the thread, which saves the operation time of changing the shuttle thread.
[0034] Although the specific implementation methods of the utility model are described above in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the utility model. On the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
