Description

Technical Field

[0001] This utility model belongs to the field of weft knitting machine accessories, and relates to an improved jacquard machine yarn feeder, including a hanger, a hanger rod, a yarn guide plate, fastening bolts, and screws. Background Technology

[0002] Currently, the yarn feeding holes and yarn guide holes in the yarn feeding nozzles of jacquard machines are mainly produced by drilling. Operators need to accurately pass the yarn through the yarn guide hole first, then through the yarn feeding hole, and finally guide it to the knitting needle. This operation method is time-consuming and labor-intensive, thus reducing the efficiency of yarn splicing and hanging. Summary of the Invention

[0003] In order to solve the problems existing in the background technology, this utility model provides an improved jacquard machine yarn feeder that can help operators quickly and effortlessly complete the yarn splicing and hanging actions.

[0004] To achieve the above objectives, the technical measures of this utility model are as follows: An improved jacquard machine yarn feeder includes a hanging base, a positioning block, a hanging rod, a yarn guide plate, fastening bolts, and screws. The hanging base is machined with a hollowed-out cavity. The positioning block is installed in the hollowed-out cavity by screws. The upper end of the hanging rod and the tail end of the yarn guide plate are both fastened to the positioning block by fastening bolts. The upper end of the hanging rod is clamped by the tail end of the yarn guide plate and the positioning block. The yarn guide plate is machined with two yarn guide holes. The yarn guide plate is characterized by having two first notches, each first notch corresponding to a yarn guide hole. A winding arm is fastened to the area where the first notch and the yarn guide hole are connected. The free end of the winding arm is suspended above the first notch. The free end of the winding arm is spaced from the top surface of the yarn guide plate by a yarn passage gap. After the yarn enters from the first notch, it is caught in the yarn passage gap and quickly enters the yarn guide hole.

[0005] Furthermore, the lower end of the boom is machined with two support arms, each with a yarn feeding hole at its extended end. Each support arm has a yarn inlet groove cut at its extended end. The depth direction of the yarn inlet groove is perpendicular to the axis of the yarn feeding hole. The yarn inlet groove cuts two coaxial holes, Hole 1 and Hole 2, into the yarn feeding hole. A second notch is machined on each side of the groove. The two second notches are offset at right angles. One second notch is connected to Hole 1, and the other second notch is connected to Hole 2. The second notch, together with Hole 1 and Hole 2, forms an offset yarn feeding hole. After entering through the second notch, the yarn quickly enters Hole 1 and Hole 2 through the yarn inlet groove.

[0006] The beneficial effect of this utility model is that it can help operators complete the yarn splicing and hanging actions quickly and effortlessly, thereby improving the efficiency of yarn splicing and hanging work. 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 1 This is a three-dimensional structural diagram of the present invention.

[0009] In the diagram: 1-Hanging base, 11-Cavity, 2-Positioning block, 3-Hanging rod, 31-Support arm, 311-Yarn inlet groove, 312-Second notch, 32-Yarn feeding hole, 4-Yarn guide plate, 41-Yarn guide hole, 42-First notch, 43-Winding arm, 5-Fasting bolt. Detailed Implementation

[0010] Figure 1 An improved jacquard machine yarn feeder is shown, comprising a hanger 1, a positioning block 2, a hanger rod 3, a yarn guide plate 4, fastening bolts 5, and screws. The top of the hanger 1 is fastened to the frame of the jacquard machine by screws. The hanger 1 has a hollowed-out cavity 11 machined by a CNC milling machine. The positioning block 2 is installed in the hollowed-out cavity 11 by screws. The upper end of the hanger rod 3 and the tail end of the yarn guide plate 4 are both fastened to the positioning block 2 by fastening bolts 5. The upper end of the hanger rod 3 is clamped by the tail end of the yarn guide plate 4 and the positioning block 2. The yarn guide plate 4 has two yarn guide holes 41 machined by a CNC milling machine. The yarn guide plate 4 has two first notches 42 machined by a CNC milling machine. Each first notch corresponds to a yarn guide hole. A winding arm 43 is fastened to the area where the first notch and the yarn guide hole are connected. The free end of the winding arm 43 is suspended above the first notch 42. The free end of the winding arm 43 is spaced from the top surface of the yarn guide plate 4 by a yarn passage gap.

[0011] The edge of the yarn guide hole 41 and the edge of the first notch 42 are both covered with a layer of synthetic resin (not shown in the figure).

[0012] like Figure 1 As shown, the lower end of the boom 3 is machined with two support arms 31 by a CNC milling machine. Each support arm 31 has a yarn feeding hole 32 machined at its extended end by a CNC milling machine. Each support arm 31 has a yarn feeding groove 311 cut at its extended end by a CNC milling machine. The depth direction of the yarn feeding groove 311 is perpendicular to the axis of the yarn feeding hole 32. The yarn feeding groove 311 cuts two coaxial holes, Hole 1 and Hole 2, into the yarn feeding hole 32. A second notch 312 is machined on both sides of the groove edge of the yarn feeding groove 311 by a CNC milling machine. The directions of the two second notches are offset at right angles. One second notch is connected to Hole 1, and the other second notch is connected to Hole 2. The second notch, together with Hole 1 and Hole 2, forms an offset yarn feeding hole.

[0013] The edges of Hole 1, Hole 2, and the second notch 312 are all covered with a layer of synthetic resin (not shown in the figure).

[0014] During operation, the worker first inserts the yarn through the first notch 42, then inserts it into the yarn passage gap and quickly enters the yarn guide hole 41. The yarn is then pulled downwards and enters through the second notch 312, then quickly enters the first and second holes through the yarn inlet groove 311. Finally, the yarn is guided to the knitting needle.
