Description
Technical field
The present invention relates to the control device of pressing knot roller in a kind of netting machine.
Background technology
As everyone knows, when the moment that the warp of netting machine breaks off relations from lower hook, pumpback arm on main shaft impacts the pumpback bar of pressing on knot axle, press knot roller to fall to the bottom rapidly under the effect of back-suction and self gravitation, now, warp be close to shuttle abdomen and with shuttle box in the damping lawn of pasting there is friction fast to anterior slippage pumpback, complete the action of cover shuttle, graticule interweaves and forms anastomose.For making to press violent the returning of unlikely generation in the time that pendulum falls fast of knot roller to lift vibration, allowing be wound in presses the warp of tying on roller to remain certain tension force, for subsequent action provides a favourable prerequisite, so, must make to press knot roller in the time that pendulum drops down onto extreme lower position, to take to brake fast and effectively vibration protection.Brake apparatus when former pressure knot roller pendulum drops down onto extreme lower position is: brake cam is installed on countershaft; Master cylinder, brake fork and brake are installed on rear internal frame; Roller is installed in one end of brake fork, and the other end is flexibly connected with fuel pump push rod, and the other end of fuel pump push rod inserts master cylinder; Press on knot axle brake disc is installed.In the time pressing knot roller pendulum to drop down onto extreme lower position, be installed on brake cam on countershaft start be installed on rear interior framework on the roller that brakes on fork contact, the fork that makes to brake swings around fork center, thereby promote fuel pump push rod and press to master cylinder, the high pressure liquid force feed of master cylinder is delivered to wheel cylinder through oil pipe, brake actuator work, presses knot roller in on-position by being installed on the brake disc braking of pressing on knot axle, forcing.But facts have proved, there is obvious technical problem in former pressure knot roller brake: press the skidding time of knot roller and position is to be determined by the installation site that is installed on countershaft overhead cam in design, countershaft is done 360 ° of revolutions, is changeless so press braking time and the position of knot roller.In the time pressing the knot fall time of roller and speed to change with external environment condition, just cannot guarantee each skidding time, press the position of knot roller all in extreme lower position, so also just cannot effectively control and press knot roller returning in the time of extreme lower position to lift oscillation phenomenon, have a strong impact on the uniformity through line tension, brought adverse effect to the accuracy of netting machine subsequent action.One of external condition of knot roller fall time and speed is pressed in impact: the thickness impact of warp.In the time that warp is thicker, the frictional resistance on warp and shuttle box internal damping lawn increases, and warp slows down to the speed of anterior slippage pumpback, presses knot roller pendulum to drop down onto just evening time of extreme lower position.Otherwise in the time that warp is thinner, warp is accelerated to the speed of anterior slippage pumpback, the time that pressure knot roller pendulum drops down onto extreme lower position is with regard to early.Two: humidity effect.In the time that humidity is larger, the frictional resistance on warp and shuttle box internal damping lawn increases, and warp slows down to the speed of anterior slippage pumpback, presses knot roller pendulum to drop down onto just evening time of extreme lower position.Otherwise, when humidity hour, warp is accelerated to the speed of anterior slippage pumpback, presses time that knot roller pendulum drops down onto extreme lower position just early.Moreover because the former design of working curve of brake cam is shorter, so the roller of cam and fork is also shorter contact time, almost can regard as is only a braking point, the braking time of cam and the adjustment of position just seem more difficult like this.Therefore, adopt this brake apparatus, operating personnel cannot be adjusted to desirable application position fast, correctly, effectively, have a strong impact on the correctness of tension force and the subsequent action of warp, finally affect the Quality and yield of net sheet.
