Description

The active type draw hook rapid resetting mechanism of negative dobby shedding device
Technical field
The utility model belongs to technical field of textile machine, especially relevant with a kind of active type draw hook rapid resetting mechanism of negative dobby shedding device.
Background technology
Negative dobby shedding device is that a kind of heald frame that drives in loom manufacture process completes the actuating unit of harness motion.Negative dobby shedding device comprises the wallboard corresponding to each other for a pair and arrange, each one group of equal and upper drag hook between wallboard of quantity each other, lower drag hook, a upper broaching tool for pull upper drag hook corresponding with drag hook on a group, a lower broaching tool for pull lower drag hook corresponding with drag hook under a group, one group equal with the quantity of upper drag hook and erect pin with the length that cantilever position is connected on upper drag hook, one group equal with lower drag hook quantity and be connected to the short perpendicular pin of lower drag hook with cantilever position and one group of respective upper end is connected with upper drag hook equally, lower end is connected with lower drag hook, and the opening connecting bar that middle part is connected with heald lifting arm, the long perpendicular pin of selecting mechanism control and short perpendicular pin are by griffing plate driving rising or decline, drag hook is meshed with lower broaching tool according to certain rules with upper broaching tool and lower drag hook, moved by the dynamic upper drag hook of pull-up knife-band, the dynamic lower drag hook motion of drop-down knife-band, thus opening connecting bar is moved, and then make the integrated box movement that is connected with opening connecting bar and realize the mouth-opening action of loom.To ensure that upper and lower broaching tool pulls upper and lower drag hook in time, then require that upper and lower drag hook can fall after rise in time, hysteresis is fallen after rise if there is upper and lower drag hook, will cause originally should being drawn by upper and lower broaching tool and the situation that is not pulled of upper and lower drag hook occur, the motion of heald frame is affected, and finally causes the quality of fabric to ensure.
The speed of loom is higher, and just corresponding requirements is faster, to ensure the opening speed of heald frame for the upper and lower drag hook falling speed of negative dobby shedding device.The raising vector of upper drag hook can be griffed the action guarantee of plate completely by long perpendicular pin, and the raising vector of lower drag hook can be griffed the action guarantee of plate equally by short perpendicular pin.But the whereabouts of upper and lower drag hook only can be fallen after rise in deadweight mode.Along with the raising of loom speed, the problem that the falling speed more and more manifesting drag hook and lower drag hook cannot match with the speed of upper and lower broaching tool, that is, the falling speed of upper and lower drag hook constitutes restriction to loom speed, and the production capacity of loom is affected.
The patent No. be 200910212931.7 patent of invention disclose a kind of draw hook rapid resetting mechanism solving negative dobby shedding device the problems referred to above, its structural principle as shown in Figure 1, draw hook rapid resetting mechanism comprises fixing with wallboard 1 and is positioned at first depression bar arm fixed axis 2 and the second depression bar arm fixed axis 6 at the one end open position of wallboard 1, first depression bar arm fixed axis 2 and the second depression bar arm fixed axis 6 are all provided with the quick fall-back device of drag hook for forcing drag hook to fall after rise fast, the quick fall-back device of drag hook comprises one and touches the depression bar 4 being against drag hook top and two the depression bar arms 3 supporting depression bar 4, one end of depression bar arm 3 is set in depression bar arm fixed axis, by being set in depression bar arm fixed axis and the fixing torsion spring of one end and depression bar arm fixed axis provides depression bar arm 3 rotary torsion, depression bar 4 is driven to touch top drag hook 5, the upper side of lower drag hook 7, for upper drag hook 5, the decline of lower drag hook 7 provides downforce, make drag hook 5, lower drag hook 7 can decline fast.But such mechanism is a kind of passive type rapid resetting mechanism of passive generation pressure, depression bar touches all the time drag hook and leans on and there is pressure, more inflexible fixing, the braiding speed of loom is still restricted, depression bar and drag hook are worn all the time, and along with drag hook unlifting pressure larger, perpendicular pin is with to griffe the pressure of plate also larger, the power consumption driving drag hook to rise is also larger, while depression bar and drag hook, erect pin and griffe plate and also more easily wear and tear.
