Working process or working principle:
During operation, the yarn passes through the balloon to enable the yarn to unwind and break the twist, then the yarn is wound in the thread groove of the yarn guide column, the wound yarn does not rub each other, no feather is generated, the yarn passing through the yarn guide column enters the yarn clamping assembly after passing through the yarn guide hole, and the yarn leaves the yarn guide hole to be kept in a straightened state in the weft accumulator.
The yarn clamping assembly comprises a threaded base fixed on the frame, an adjusting nut is connected to the threaded base in a threaded manner, a lower clamping plate is arranged on the adjusting nut, a supporting rod is arranged on the lower clamping plate, an upper clamping plate and an adjusting plate are connected to the supporting rod, a spring is arranged between the upper clamping plate and the adjusting plate, the height of the lower clamping plate is controlled by the adjusting nut to adapt to different production requirements, the height of the lower clamping plate on the supporting rod is adjusted by rotating the adjusting plate so as to adjust the initial elasticity of the spring, and therefore the clamping force between the upper clamping plate and the lower clamping plate is controlled, and yarns leave a yarn guide hole to be kept in a straightened state by a weft accumulator.
The thread crests and roots of the thread of the yarn guide column are rounded, so that friction of right angles to yarns is reduced, and damage to the yarns is avoided.
The thread inclination angle in the yarn guide column is 10-30 degrees, theoretically, the smaller the degree is, the better the degree is, the more favorable for yarn winding and difficult derailment, but the thread is required to be smooth and has radian, the thread pitch of the yarn guide column is small if the degree is too small, the use is unfavorable, the larger yarn is easy to derail, and the most suitable range is 10-30 degrees.
The yarn guide column is internally provided with a connecting hole which is vertically communicated, and the yarn guide column is conveniently disassembled, assembled and replaced through the connecting hole.
The yarn guide column is made of ceramic materials.
Compared with the prior art, the utility model has the beneficial effects that:
The utility model uses the spiral yarn guide column to reduce the mutual friction between yarns when the yarns pass through the yarn guide column, thereby avoiding the generation of feathers, reducing the damage to the quality of the yarns and further solving the problem that three or more weft yarns in one weaving port are woven into cloth to cause weft shedding.
