Detailed ways

The present invention will be described in further detail below in conjunction with the embodiments.

The present embodiment proposes a left and right moving box for an open heald frame, as shown in Figures 1 to 4, comprising a box body 1 and a left and right moving rod 2. The box body 1 is rotatably connected with an input shaft 3, a transmission shaft 1 4, The second transmission shaft 5 and the output shaft 6, the end of the input shaft 3 located in the box body 1 is provided with a bevel gear 1 7, the transmission shaft 1 4 is fixed with a transmission gear 1 9 and a bevel gear meshing with the bevel gear 1 7. The second gear 8, the second transmission shaft 5 is fixed with the second transmission gear 10 and the third transmission gear 11 meshing with the transmission gear 1 9, the output shaft 6 is fixed with a cam 12 and an output gear 17 meshed with the second transmission gear 10, so The inner wall of the box body 1 is provided with two fixed blocks 13, the fixed blocks 13 are provided with linear bearings, the left and right moving rods 2 and the fixed blocks 13 are connected by linear bearings, and the left and right moving rods 2 are fixed with stoppers 14. The linear bearing provides guidance for the movement of the left and right moving rods 2, ensuring that the moving route is on the same straight line. There are two blocks 14 located on both sides of the cam 12 . The transmission ratio between the input shaft 3 and the output shaft 6 is 1:6. Preferably, the first bevel gear 7 and the second bevel gear 8 have the same size, the first transmission gear 9 and the third transmission gear 11 , The diameter ratio of the second transmission gear 10 and the output gear 17 is 1:2:1:3.

Wherein, the top of the block 14 is provided with a mounting hole and a screw hole passing through the mounting hole, the screw hole is threadedly connected with a fastening screw 15, and the left and right moving rods 2 pass through the mounting hole and are fastened by the fastening screw 15; The lower part of the block 14 is provided with an installation groove, and the installation groove is provided with a roller 16 opposite to the cam 12 . By tightening the screws 15 to fix the block 14 and the left and right moving rods 2, it is convenient to adjust the position of the block 14 on the left and right moving rods 2 according to the needs, so as to adjust the left and right moving range of the left and right moving rods 2; The contact between the cam 12 and the block 14 is rolling friction, which reduces the friction between the cam 12 and the block 14 and improves the smoothness of the movement of the left and right moving rods 2 .

The transmission route of this embodiment is as follows: the external drive device drives the bevel gear 1 to rotate through the input shaft 3 , the bevel gear 1 7 transmits the power to the bevel gear 2 8 , and the bevel gear 2 8 passes the transmission shaft 1 4 .
