Description

Technical Field

[0001] The utility model relates to a warp knitting machine, in particular to a main shaft transmission structure of a double needle bed warp knitting machine. Background Art

[0002] Usually double needle bed warp knitting machines such as Figure 1 As shown, it includes a front bed 101' and a rear bed 102', the front bed 101' is installed with a single-axis connecting rod frame 10', the rear bed is installed with a double-axis connecting rod frame 20', the double-axis connecting rod frame is installed with a first part 30', a second part 40' and a third part 50', due to the need for the warp knitting machine to form a loop, the speed of the third part 50' on the rear bed must be three times that of the first part 30' and the second part 40', so the third part 50' must be driven by a double axis; the single-axis connecting rod frame is installed with a fourth part 60', a fifth part 70' and a sixth part 80'. The main shaft transmission structure of the warp knitting machine is as shown in FIG. Figure 1 As shown, it includes a main motor 1', a main motor pulley 2', a main motor belt 3', a first pulley 4', a first main shaft 5', a second pulley 6', a double-sided toothed belt 7', a second main shaft 8', a third pulley 9', a tensioner 10', a third main shaft 11', a triple-speed large pulley 12', a triple-speed small pulley 13', a tensioner 14', a belt 15' and other auxiliary devices. The first main shaft 5' is installed on the single-axis connecting rod frame 10' on the front bed, the second main shaft 8' and the third main shaft 11' are installed on the double-axis connecting rod frame 20' on the rear bed, the main motor pulley 2' is connected to the first pulley 4' through the main motor belt 3', the second pulley 6' is connected to the third pulley 9' through the double-sided toothed belt 7', the triple-speed large pulley 12' is connected to the triple-speed small pulley 13' through the belt 15', and each pulley is rigidly connected to the main shaft connected to it and rotates therewith.

[0003] During transmission, the main motor 1' drives the first main shaft 5' to rotate, and the rotation of the first main shaft 5' drives the second main shaft 8' of one line to rotate through the second pulley 6', thereby driving the parts 30' and 40' on the second main shaft 8' to move; the rotation of the first main shaft 5' drives the parts 60', 70' and 80' on the front bed to move, and drives the part 50' on the third main shaft 11' of another line to move through the triple-speed large pulley 12' and the triple-speed small pulley 13'. The defect of the transmission device of the main shaft of the double needle bed warp knitting machine is that the transmission path is long and the transmission efficiency needs to be improved.
