Abstract
Description
Technical Field
[0001] This utility model belongs to the field of weft knitting machine accessories, and relates to an improved yarn feeder used in towel machines, including a hanging base, a lifting adjustment rod, a yarn guide wheel, a wheel axle, and a bearing. Background Technology
[0002] Currently, the yarn feeding nozzles used in towel machines often experience yarn breakage during actual use because the yarn feeding plate is glued to the bottom of the lifting adjustment rod. This can cause the yarn guide wheel and the yarn feeding hole of the yarn feeding plate to have an excessively large or small guiding angle, and the angle cannot be flexibly adjusted. Ultimately, this situation affects the weaving effect of the fabric. Summary of the Invention
[0003] In order to solve the problems existing in the background technology, this utility model provides an improved yarn feeding nozzle that can flexibly adjust the yarn guiding angle when applied to a towel machine.
[0004] To achieve the above objectives, the specific technical measures of this utility model are as follows: An improved yarn feeder for use in a towel machine includes a hanging base, a lifting adjustment rod, a yarn guide wheel, a wheel axle, and a bearing. The hanging base has an L-shaped structure. The middle part of the lifting adjustment rod is machined with a hollowed-out lifting adjustment hole. The lifting adjustment hole of the lifting adjustment rod is fastened to the back of the vertical part of the hanging base by a first bolt. A wheel axle is horizontally connected to the side wall of the vertical part of the hanging base. The wheel axle is fixed by a locking screw. A bearing is sleeved on the protruding end of the wheel axle. A yarn guide wheel is sleeved around the bearing. The invention is characterized by further including a swing-type yarn feeder. The bottom of the lifting adjustment rod is machined with an upwardly recessed groove. The bottom of the lifting adjustment rod is machined with... There is a pin hole and a bolt hole. The bolt hole is located above the pin hole. The upper end of the oscillating yarn feeder has a fan-shaped structure and is integrally formed with a pin hole and an arc-shaped adjustment hole. The arc-shaped adjustment hole is located above the pin hole. The upper end of the oscillating yarn feeder is inserted upward into the groove at the bottom of the lifting adjustment rod. After the pin hole is aligned with the pin hole, a pin is inserted. The pin serves as the oscillation axis of the oscillating yarn feeder. The second bolt is screwed into the bolt hole and passes through the arc-shaped adjustment hole. The oscillating yarn feeder swings within the range of the arc-shaped adjustment hole. When the optimal yarn guiding angle between the guide wheel and the oscillating yarn feeder is adjusted, the second bolt is tightened to narrow the groove at the bottom of the lifting adjustment rod. After the groove is narrowed, the oscillating yarn feeder can be firmly clamped.
[0005] Among them, the oscillating yarn feeding plate is integrally formed and has multiple fine-diameter yarn feeding holes.
[0006] Furthermore, it also includes a positioning block. The upper end of the lifting adjustment rod is machined with a hollow positioning adjustment hole. The positioning adjustment hole of the lifting adjustment rod is fastened with a positioning block by a third bolt. The positioning block is located on the front side of the lifting adjustment rod and above the horizontal part of the hanging seat.
[0007] The beneficial effect of this utility model is that it can flexibly adjust the yarn guiding angle of the yarn guide wheel and the oscillating yarn feeder, thereby effectively reducing the number of yarn breaks during yarn guiding. Attached Figure Description
[0008] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

Detailed Implementation
[0011] Figure 1 An improved yarn feeder for use in a towel machine is shown, comprising a support, a lifting adjustment rod 2, a yarn guide wheel 3, a wheel axle 31, and a bearing. The support has an L-shaped structure. The horizontal part 11 of the support is fastened to the frame of the towel machine by screws. The middle part of the lifting adjustment rod 2 has a hollowed-out lifting adjustment hole machined by a CNC milling machine. The lifting adjustment hole of the lifting adjustment rod is fastened to the back of the vertical part 12 of the support by a first bolt 21. A wheel axle 31 is horizontally connected to the side wall of the vertical part 12 of the support and is fixed by a locking screw. The protruding end of the wheel axle 31 is sleeved with a bearing, and the yarn guide wheel 3 is sleeved around the bearing. The feature is that it also includes a swing-type yarn feeder A, and the bottom of the lifting adjustment rod 2 is open. The bottom of the lifting adjustment rod 2 is machined with an upwardly recessed groove 22 by a CNC milling machine. The bottom of the lifting adjustment rod 2 is machined with a pin hole 221 and a bolt hole 222 by a CNC milling machine. The bolt hole 222 is located above the pin hole 221. The upper end of the oscillating yarn feeder A has a fan-shaped structure and is integrally formed with a pin hole 2 and an arc-shaped adjustment hole A1. The arc-shaped adjustment hole A1 is located above the pin hole 2. The upper end of the oscillating yarn feeder A is inserted upward into the groove 22 at the bottom of the lifting adjustment rod 2. After the pin hole 2 and the pin hole 221 are aligned, a pin B is inserted. The pin B serves as the oscillation axis of the oscillating yarn feeder A. The second bolt C is screwed into the bolt hole 222 and passes through the arc-shaped adjustment hole A1. The oscillating yarn feeder A oscillates within the range of the arc-shaped adjustment hole A1.
[0012] When the optimal yarn guiding angle between the guide wheel 3 and the oscillating yarn feeder A is adjusted, tighten the second bolt C to narrow the groove 22 at the bottom of the lifting adjustment rod 2. After the groove 22 is narrowed, it can firmly clamp the oscillating yarn feeder A, thereby effectively reducing the number of yarn breaks during the yarn guiding process.
[0013] The oscillating yarn feeding plate A is integrally formed and has multiple fine-diameter yarn feeding holes.
[0014] like Figure 1 As shown, the bolt shank of the first bolt 21 and the bolt shank of the second bolt C are both fitted with telescopic springs and washers.
[0015] like Figure 1 As shown, it also includes a positioning block 4. The upper end of the lifting adjustment rod 2 is machined with a hollow positioning adjustment hole by a CNC milling machine. The positioning adjustment hole of the lifting adjustment rod 2 is fastened with the positioning block 4 by the third bolt 41.
