Embodiment Construction
[0012] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0013] Such as figure 1 As shown, the present invention includes a corner 1, a corner knife holder 3 for installing the corner 1, a corner needle holder 2 for pushing the corner 1 up and down, a linear drive mechanism 5, a wedge-shaped transmission device, and a drive rod 4 for driving the corner needle holder 2 up and down , Drive rod reset device and drive rod limit device. The linear drive mechanism is a linear motor. The linear motor control has fast response speed, high sensitivity and good follow-up, so the sensitivity, rapidity and follow-up of the density adjustment system can be improved. The driving direction of the linear motor is the horizontal direction, and the wedge-shaped transmission device includes a wedge-shaped rod 9 with a wedge-shaped end. The motor shaft of the linear motor is connected to the wedge-shaped rod 9. The in...

The invention discloses a linear driving density device of a knitting cotton sock machine and belongs to the field of cotton sock machine parts.An existing cotton sock machine corner lifting device has the defects of poor operation stability and low locating precision.The linear driving density device comprises a corner, a corner knife holder for installing the corner, a corner holding needle knife, a linear driving mechanism, a wedge transmission device, a driving rod for driving the corner holding needle knife to be lifted, a driving rod resetting device and a driving rod limiting device.The driving direction of the linear driving mechanism is the horizontal direction.The linear driving mechanism drives the driving rod to be lifted through the wedge transmission device.The driving rod limiting device is arranged on the corner knife holder to limit the ascending height of the driving rod.The driving rod resetting device is connected with the driving rod to achieve descending and resetting of the driving rod.By controlling linear driving of the linear driving mechanism, high-precision control over any position of the triangle driving rod can be achieved through the wedge transmission device, the locating precision of a density adjusting system is improved, and the service life is prolonged.
Description
technical field [0001] The invention belongs to the field of cotton hosiery machine components, and in particular relates to a linear drive density device for a knitted cotton hosiery machine. Background technique [0002] The existing cotton hosiery machine density adjustment device mainly drives the eccentric cam through the stepper motor, and then drives the angular slider device through the connecting rod device to realize the density adjustment control. The patent publication number is that CN202881616U discloses a kind of cotton hosiery machine water chestnut lifting device, and it comprises lever, and the cam and the water chestnut that are positioned at both sides of the lever, the cam is located at the bottom of the lever, and the water chestnut is located at the top of the lever. However, the traditional mechanical linkage density adjustment device has a complex structure, poor running stability, low positioning accuracy, cannot achieve high-precision arbitrary pos...
