Detailed description of the invention
Below in conjunction with accompanying drawing and the course of work, the utility model is described in further detail, but is not the restriction to the utility model protection domain.
As shown in Figure 1, a kind of roller sewing machine roller press clutch, comprise electromagnet 2, magnet steel axle 14 and unidirectional Bearing rotating mechanism, be connected by an eccentric shaft structure between electromagnet 2 with unidirectional Bearing rotating mechanism, unidirectional Bearing rotating mechanism comprises unidirectional Bearing axle 3, unidirectional bearing seat 4, and unidirectional Bearing axle 3 upper end is provided with Bearing axle bearing 5; Eccentric shaft structure comprises eccentric shaft 13, eccentric shaft locating piece 8 and eccentric shaft contiguous block 7, and eccentric shaft 13 one end is connected with Bearing axle bearing 5, and eccentric shaft 13 other end is connected with magnet steel axle 14 by eccentric shaft contiguous block 7.Bearing axle bearing 5 upper end is provided with slide plate 12, and handpiece case 1 is provided with limited block 9, is provided with the chute 10 coordinating slide plate 12 in limited block 9.Eccentric shaft contiguous block 7 comprises an axle sleeve 71 and is fixed on the connecting rod 72 of axle sleeve 71 one end, and axle sleeve 71 other end connects eccentric shaft 13, and connecting rod 72 is connected with magnet steel axle 14 by a pull bar 6.
As shown in Figure 2, this roller press clutch is arranged in handpiece case 1, and described limited block 9 upper end is fixed on handpiece case 1 by a connecting piece 11 and trip bolt.
The course of work of the present utility model: when the presser feet gear of roller sewing machine needs to throw off, electromagnet is energized, pull bar is pulled by magnet steel axle, pull bar drives eccentric shaft turns by eccentric shaft contiguous block, and eccentric shaft drives Bearing axle up to lift by Bearing axle bearing, and presser feet gear (presser feet gear is connected to the bottom of unidirectional Bearing axle) is thrown off, just play clutch action, upper cloth pressing wheel loses rotating forward power, and the Reverse Power of cloth pressing wheel drives on the lower, and it is steadily backstitched.
The utility model adopts eccentric lever principle, namely eccentric shaft coordinates unidirectional Bearing rotating mechanism to control the clutch of presser feet gear, what make that it can be reliable and stable is out of gear presser feet or engages, and presser feet gear can be coordinated with cloth pressing wheel smoothly, thus ensure that it steadily backstitches.
