Description

Technical Field

[0001] This utility model belongs to the field of weft knitting machine accessories and relates to a new type of yarn feeder for use in a towel jacquard machine, including a hanging base, a lifting adjustment rod, a yarn guide wheel, a wheel axle, a bearing, and a yarn feed plate. Background Technology

[0002] Currently, in the actual use of yarn feeding nozzles applied to towel jacquard machines, the yarn guide wheel is fixedly installed on the lifting adjustment rod by a wheel shaft, while the yarn feeding plate is fixedly installed at the bottom of the lifting adjustment rod by glue. This causes the yarn guiding angle of the yarn guide wheel and the yarn feeding plate to be unable to be flexibly adjusted, resulting in problems such as uneven yarn feeding or even yarn breakage. This situation ultimately 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 a new type of yarn feeding nozzle that can flexibly adjust the yarn guide angle for use in a towel jacquard machine.

[0004] To achieve the above objectives, the specific technical measures of this utility model are as follows: A novel yarn feeder for a towel jacquard machine includes a hanging base, a lifting adjustment rod, a yarn guide wheel, a wheel axle, a bearing, and a yarn feed plate. 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. The upper end of the yarn feed plate is fastened to the bottom of the lifting adjustment rod by glue. The yarn feed plate is integrally formed with a yarn feed hole. The feature is that it also includes a rotating block. The rotating block is connected to the lower end of the lifting adjustment rod by a second bolt and is located above the yarn feed plate. A wheel axle is horizontally connected to the rotating block. The wheel axle is fixed by a locking bolt. The protruding end of the wheel axle is sleeved with a bearing. A yarn guide wheel is sleeved around the bearing. The tilt angle of the yarn guide wheel is controlled by adjusting the rotation angle of the rotating block. When the tilt angle of the yarn guide wheel reaches the optimal yarn guide angle with the yarn feed hole of the yarn feed plate, the second bolt is tightened and the rotating block is fixed in place.

[0005] 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.

[0006] The beneficial effect of this utility model is that it can flexibly adjust the yarn guiding angle between the yarn guide wheel and the yarn feeding hole of the yarn feeding plate. Attached Figure Description

[0007] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0008] Figure 1This is a three-dimensional structural diagram of the present invention.

[0009] In the diagram: 11-Horizontal part, 12-Vertical part, 2-Lifting adjustment rod, 21-Lifting adjustment hole, 22-First bolt, 221-Telescopic spring, 222-Shim, 3-Yarn guide wheel, 31-Wheel shaft, 4-Yarn feed plate, 5-Positioning block, 51-Third bolt, A-Rotating seat block, A1-Second bolt. Detailed Implementation

[0010] Figure 1 A novel yarn feeder for a towel jacquard machine is shown, comprising a mounting base, a lifting adjustment rod 2, a yarn guide wheel 3, a wheel axle 31, a bearing, and a yarn feed plate 4. The mounting base has an L-shaped structure, and the horizontal part 11 of the mounting base is fastened to the frame of the towel jacquard machine by screws. The middle part of the lifting adjustment rod 2 has a hollowed-out lifting adjustment hole 21 machined by a CNC milling machine. The lifting adjustment hole 21 of the lifting adjustment rod 2 is fastened to the back of the vertical part 12 of the mounting base by a first bolt 22. The upper end of the yarn feed plate 4 is glued in place. The feeding plate 4 is integrally formed with a feeding hole and is fixedly installed at the bottom of the lifting adjustment rod 2. The feature is that it also includes a rotating seat block A. The rotating seat block A is connected to the lower end of the lifting adjustment rod 2 by a second bolt A1 and is located above the feeding plate 4. A wheel axle 31 is connected horizontally in series with the rotating seat block A. The wheel axle 31 is fixed by a locking bolt. A bearing is sleeved on the protruding end of the wheel axle 31. A guide wheel 3 is sleeved around the bearing. The tilt angle of the guide wheel 3 is controlled by adjusting the rotation angle of the rotating seat block A.

[0011] When the inclination angle of the guide roller 3 reaches the optimal guiding angle with the feeding hole of the feed plate 4, the operator tightens the second bolt A1 and secures the rotating block A. The operator then guides the yarn around the guide roller 3 to the feeding hole of the feed plate 4 and finally feeds it to the knitting needle.

[0012] The first bolt 22 has a telescopic spring 221 and a washer 222 connected to its shank.

[0013] like Figure 1 As shown, it also includes a positioning block 5. 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 5 by the third bolt 51. The positioning block 5 is located on the front side of the lifting adjustment rod 2 and above the horizontal part 11 of the hanging seat.
