Description
Technical Field
The utility model belongs to the technical field of knitting machinery, in particular to flat knitting machine's yarn pressing device.
Background
In the flat knitting machine, in the initial stage, yarns on a bobbin pass through a yarn nozzle and are clamped to a scissors clamp, and the scissors clamp is located close to the initial position of the yarn nozzle. When the needle is lifted, the yarn nozzle is positioned at the initial position and is close to the scissors clamp, so that the inclination angle of the yarn from the scissors clamp to the yarn nozzle is too large, and the yarn feeding angle of the yarn nozzle is a little steep. At this time, the yarn is not yet wound into the roller device, and during the needle raising knitting or the knitting with a certain range of needle adding and yarn adding, a part of knitting needles on the side of the needle bed close to the scissors clamp are easy to have the phenomenon that the yarn is not stably hooked or even the yarn cannot be hooked. Therefore, when no waste yarn is used for lifting, the first knitting needle cannot be guaranteed to be stably hooked to the yarn for lifting, the needle lifting position needs to be backed, or the needle cannot be added to the full needle range when the yarn adding knitting is needed in the needle adding process, the fabric quality is influenced, and the production efficiency is also reduced.
Disclosure of Invention
The utility model aims at providing a flat-bed machine's yarn pressing device can push down the yarn, makes the yarn be drawn into the roller as early as possible, perhaps the knitting needle can collude the line smoothly and steadily, normally weaves.
Therefore, the technical scheme of the utility model is that: the utility model provides a flat-bed machine's yarn pressing device which characterized in that: the yarn pressing motor is arranged on the base, the tail of the yarn pressing rod is arranged on a shaft of the yarn pressing motor, and the shaft drives the yarn pressing rod to rotate; the base is provided with an upper limit pin and an inductor which correspond to the two end points of the rotating path of the yarn pressing rod.
Furthermore, a lower limiting pin is further arranged on the base and corresponds to the position of the inductor.
Furthermore, the head of the yarn pressing rod is in a hook shape, and the yarn pressing rod is also provided with an inward-concave yarn pressing groove.
Furthermore, the base comprises a bottom plate and an installation plate, and the yarn pressing motor and the yarn pressing rod are positioned on two sides of the installation plate; the middle of the mounting plate is provided with a long groove, a horn-shaped opening is arranged above the long groove, and the bottom of the arc groove is arranged below the long groove.
The base of the utility model is arranged on the bracket at one side of the needle bed and is positioned between the clip of the scissors and the initial position of the yarn nozzle; when the knitting is carried out by the set-up knitting or the knitting is carried out by adding needles within a certain range and adding yarns, the yarn pressing motor drives the yarn pressing rod to rotate, the yarn can be pressed down in the rotating process of the yarn pressing rod, the yarn is pressed into the long groove in the middle of the mounting plate by the yarn pressing rod in the yarn pressing process, and finally the yarn slides down to the space formed by the yarn pressing groove and the arc groove bottom on the mounting plate, so that the yarn cannot deviate from the position of a knitting needle; the yarn pressing rod presses the yarn to the hooking range of the knitting needle, so that the knitting needle can stably hook the yarn. The initial position of the yarn pressing rod is limited by the upper limiting pin, and the working position can be determined by the inductor; and in order to prevent the sensor from malfunctioning, a lower limiting pin is further arranged on the base to limit the working position of the yarn pressing rod.
The utility model adds a yarn pressing device between the scissor clamp and the initial position of the yarn nozzle, which is convenient for yarn to be rolled into the roller as early as possible; when the knitting is carried out by lifting or adding and plating, the knitting needles at any positions on the needle plate can smoothly hook and pull yarns, so that full knitting is realized, the requirements of customers on fabrics are met, and the knitting cost and the labor cost are greatly reduced.
Drawings
The following detailed description is made with reference to the accompanying drawings and embodiments of the present invention
Fig. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic view of the rotation of the yarn pressing rod of the present invention;
fig. 3 is a schematic view of the operation of the present invention.
Labeled as: the yarn pressing device comprises a yarn pressing motor 1, a yarn pressing rod 2, a yarn pressing groove 21, a bottom plate 3, a mounting plate 4, a long groove 41, a sensor 5, an upper limiting pin 6, a lower limiting pin 7, yarns 8, a yarn nozzle 9, a yarn pressing device 10, a scissors clamp 11, a roller 12 and a knitting needle 13.
Detailed Description
See the drawings. The yarn pressing device 10 comprises a base, a yarn pressing motor 1 and a yarn pressing rod 2, wherein the base comprises a bottom plate 3 and a mounting plate 4, the bottom plate 3 is perpendicular to the mounting plate 4, and the bottom plate is fixed on a bracket on one side of a needle bed through a screw; the yarn pressing motor 1 is arranged on the back of the mounting plate 4, the mounting plate is provided with a through hole for a motor shaft to pass through, the yarn pressing rod 2 is positioned on the front of the mounting plate 4, and the tail part of the yarn pressing rod 2 is arranged on the motor shaft and is driven by the motor shaft to rotate; the head of the yarn pressing rod 2 is arranged into a hook shape, so that the yarn can be pressed down conveniently, and the yarn pressing rod is also provided with an inward concave yarn pressing groove 21. The middle of the mounting plate 4 is provided with a long groove 41, a horn-shaped opening is arranged above the long groove, and the bottom of the arc groove is arranged below the long groove. After the head of the yarn pressing rod hooks the yarn, the yarn pressing rod rotates downwards to press the yarn downwards, meanwhile, the yarn enters the long groove 41 through the horn-shaped opening, so that the yarn cannot deviate from the position of the knitting needle, and finally, the yarn slides downwards from the head of the yarn pressing rod to a space formed by the yarn pressing groove 21 and the arc groove bottom of the long groove 41, and the knitting needle hooks the yarn conveniently.
