For achieving the above object, the technical scheme that the utility model is taked is: a kind of lower opening device of loom, and it comprises frame and is installed on power input shaft, power transmission shaft, cam mechanism, opening arm, connecting rod, heald frame power transmission shaft, heald frame elevating lever and the heald frame in frame; Wherein, described power input shaft installs a drive sprocket; Be provided with one by movable sprocket in one end of described power transmission shaft, the other end is provided with drive sprocket; Describedly to be connected by one first driving chain with drive sprocket by movable sprocket, and to realize 1:1 transmission; Described cam mechanism is connected with a power input sprocket, this power input sprocket is connected by one second driving chain with drive sprocket, and realizes 1:1 transmission; Described opening arm is provided with two, and it is connected to cam mechanism respectively, and is driven by cam mechanism; The top of described connecting rod is pivoted on opening arm, and bottom is connected on heald frame power transmission shaft; The bottom of described heald frame elevating lever is connected on heald frame power transmission shaft, and top is connected on heald frame; Described heald frame is positioned at the top of cam mechanism.
The lower opening device of loom of the present utility model is set to further: described heald frame power transmission shaft is specifically provided with two, and the two ends of each heald frame power transmission shaft are respectively equipped with a support arm, are provided with an elongated slot in support arm; The bottom of described connecting rod is fixed in the elongated slot of a wherein support arm; The bottom of described heald frame elevating lever is fixed in the elongated slot of another support arm.
The plurality of advantages such as compared with prior art, the utility model has following beneficial effect: it is simple that the lower opening device of loom of the present utility model has structure, good stability, and the little and transmission speed of taking up room is fast.
Accompanying drawing explanation
Fig. 1 is the schematic perspective view of the lower opening device of loom of the present utility model.
Fig. 2 is the schematic perspective view at another visual angle of lower opening device of loom of the present utility model.
Detailed description of the invention
Refer to shown in Figure of description 1 and accompanying drawing 2, the utility model is a kind of lower opening device of loom, and it is by frame 1 and be installed on several parts such as power input shaft 2, power transmission shaft 3, cam mechanism 4, opening arm 5, connecting rod 6, heald frame power transmission shaft 7, heald frame elevating lever 8 and heald frame 9 in frame 1 and form.
Wherein, described power input shaft 1 is connected with dynamical system (not shown), installation one drive sprocket 10 on it.
Be provided with one by movable sprocket 11 in one end of described power transmission shaft 3, the other end is provided with drive sprocket 12.Describedly to be connected by one first driving chain 13 with drive sprocket 10 by movable sprocket 11, and to realize 1:1 transmission, namely realize power input shaft 1, drive sprocket 10, by the transmission successively of movable sprocket 11, power transmission shaft 3, drive sprocket 12.
Described cam mechanism 4 is connected with a power input sprocket 14, this power input sprocket 14 is connected by one second driving chain 15 with drive sprocket 12, and realize 1:1 transmission, namely realize the transmission successively of drive sprocket 12, power input sprocket 14, cam mechanism 4.
Described opening arm 5 is provided with two, and it is connected to cam mechanism 4 respectively, and is driven by cam mechanism 4.
The top of described connecting rod 6 is pivoted on opening arm 5, and is driven and oscilaltion by opening arm 5.The bottom of this connecting rod 6 is connected on heald frame power transmission shaft 7, and thus drives heald frame power transmission shaft 7 reciprocating rotating.
The bottom of described heald frame elevating lever 8 is connected on heald frame power transmission shaft 7, and top is connected on heald frame 9.Due to heald frame power transmission shaft 7 reciprocating rotating, it drives the oscilaltion of heald frame elevating lever 8, linkage heald frame 9 oscilaltion and realize the mouth-opening action of heald frame 9.
Described heald frame 9 is positioned at the top of cam mechanism 4, because cam mechanism 4 is positioned at the below of heald frame 9, which reduces taking up room of loom, makes stable drive simultaneously.
Further, described heald frame power transmission shaft 7 is specifically provided with two, and the two ends of each heald frame power transmission shaft 7 are respectively equipped with a support arm 16, are provided with an elongated slot 17 in support arm 16.The bottom of described connecting rod 6 is fixed in the elongated slot 17 of a wherein support arm 16; The bottom of described heald frame elevating lever 8 is fixed in the elongated slot 17 of another support arm 16.And by changing connecting rod 6 and the position of heald frame elevating lever 8 in elongated slot 17, thus convenience adjustment can be carried out according to need of production.
Above detailed description of the invention is only the preferred embodiment of this creation, and not in order to limit this creation, any amendment made within all spirit in this creation and principle, equivalent replacement, improvement etc., within the protection domain that all should be included in this creation.
