Description

Technical Field

[0001] The utility model relates to the technical field of knitting machines, in particular to a yarn feeding mechanism of a knitting machine. Background Art

[0002] Knitting machines use knitting needles to form coils of yarns of various materials and types, and then connect them into knitted fabrics through stringing. Knitted fabrics are soft, have good wrinkle resistance and breathability, and have greater extensibility and elasticity, making them comfortable to wear. Knitting can be divided into two categories: hand knitting and machine knitting.

[0003] Through patent search, it was found that a yarn feeding mechanism for a single-sided circular knitting machine with publication number CN218756347U is provided with a support spring, a support plate and a wax block in sequence through the top of the bottom plate, and the bottom plate is located at the lower end of the wire hole, so that the yarn passing through the wire hole is fully in contact with the wax block, which moisturizes and lubricates the yarn and the circumferential inner wall of the ceramic sleeve, thereby reducing the friction between the yarn and the circumferential inner wall of the ceramic sleeve, and the support spring extends as the wax block decreases, so that the wax block is always close to the yarn to ensure the lubrication effect. The relative positions of the two sets of wire holes in the above-mentioned comparative document cannot be adjusted, and the angle cannot be fine-tuned either, so there are certain limitations in its use.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-3 , comprising: a yarn feeding seat 1 and a yarn guide plate 2 fixedly connected to the bottom of the yarn feeding seat 1, a group of adjusting slots 3 are provided inside the yarn guide plate 2, and two groups of spaced yarn reversing nozzles 5 are provided in the cavity of the adjusting slots 3, the yarn reversing nozzles 5 are spherical, and a group of circular channels are passed through the yarn reversing nozzles 5, and the circular channels are used for threading, and a group of rectangular slots are provided on the side wall of the yarn guide plate 2, the rectangular slots are connected to the cavity of the adjusting slots 3, an adjusting kit 6 is provided on one side wall of the yarn reversing nozzle 5, and the adjusting kit 6 extends outward through the rectangular slot, and A group of positive and negative screw rods 7 are arranged on the side wall of the yarn guide plate 2, wherein the uppermost end of the positive and negative screw rods 7 is located above the rectangular groove, and the lowermost end of the positive and negative screw rods 7 is also located below the rectangular groove, and a grip portion is arranged at the lowermost end. The adjustment kit 6 passes through the rectangular groove and is sleeved on the outside of the positive and negative screw rods 7 and engages with the positive and negative screw rods 7. Therefore, by operating the rotation of the positive and negative screw rods 7, the adjustment kit 6 can be moved, and the synchronous movement of the two groups of adjustment kits 6 can drive the yarn reversing nozzle 5 to synchronously change the spacing in the cavity of the adjustment slot 3.

[0025] The cam 8 is a substantially parallel plate 9 which is arranged on the inner wall of the guide plate 2 and away from the rectangular groove. A stabilizing cross plate 9 is arranged on the end of the guide plate 2 and away from the adjusting kit 6. One end of the stabilizing cross plate 9 can be inserted into the groove of the stabilizing cross plate 4 and can slide in the groove of the stabilizing cross plate 4. In this way, the movement stability of the two groups of guide plates 5 can be improved. An angle adjustment groove 8 is arranged on the surface of the guide plate 5. An adjusting plug 11 is fixedly arranged on the other end of the stabilizing cross plate 9. The front end of the adjusting plug 11 is arc-shaped and matched with the arc-shaped groove of the angle adjustment groove 8. Therefore, the adjusting plug 11 can slide in the groove of the angle adjustment groove 8. The end of the adjusting kit 6 away from the positive and negative screw rods 7 can also interact in the groove of the angle adjustment groove 8. Therefore, the opening direction angle of the guide plate 8 can be changed independently.

[0026] In order to complete the locking of the inverted yarn mouth 5 after the angle adjustment, cavities are set in the adjustment plug block 11 and the stabilizing cross plate 9, and the two cavities are connected, and four groups of sockets are set on the surface of the adjustment plug block 11, the sockets are connected with the cavities, and the positioning rods 13 are inserted in the sockets. A part of the positioning rod 13 extends into the cavity, and a main pressure rod 12 is fixed at one end. An opening allowing the main pressure rod 12 to slide is opened on the surface of the stabilizing cross plate 9, and the main pressure rod 12 and the positioning rod 13 are U-shaped in cross section, and the main pressure rod 12 and the positioning rod 13 are set in two groups, so that the two groups of U-shaped are distributed back to back. A plurality of springs 14 are installed between the two groups of positioning rods 13. Under the elastic drive of the springs 14, the main pressure rod 12 and the positioning rod 13 protrude upward. Therefore, since the positioning rod 13 protrudes outward from the adjusting plug block 11, the top of the positioning rod 13 is in close contact with the upper and lower inner walls of the angle adjustment slot 8, and the angle of the yarn reversing nozzle 5 is fixed by friction. When the angle of the yarn reversing nozzle 5 needs to be adjusted, the main pressure rod 12 only needs to be pressed downward to retract the positioning rod 13 into the insertion hole of the adjusting plug block 11, and the angle of the yarn reversing nozzle 5 can be changed by sliding the adjusting plug block 11 and the angle adjustment slot 8.
