[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 2 to 4This utility model provides an embodiment of a knitting machine head structure for increasing fabric density, comprising a needle body 1 and a positioning box 4. A locking assembly for locking with an external structure is fixedly connected to the top of the needle body 1. The locking assembly includes a connecting post 2, the bottom of which is fixedly connected to the top of the needle body 1. Changes in the position of the connecting post 2 cause changes in the position of the needle body 1. An external rod 8 is fixedly connected to the top of the connecting post 2, and changes in the position of the connecting post 2 cause changes in the position of the external rod 8. The top of the external rod 8 is fixedly connected to the bottom of a pointed needle 12, and changes in the position of the external rod 8 cause changes in the position of the pointed needle 12.

[0034] A pin 12 is fixedly connected to the top of the locking assembly, and a sliding box 6 is slidably connected inside the positioning box 4, allowing the position of the sliding box 6 to be flexibly adjusted. The pin 12 is externally slidably connected to the inner wall of the positioning box 4, providing an opportunity for the pin 12 to engage. Two latches 11 are formed inside the sliding box 6, and movable balls 10 (as shown in the attached diagram) are movably connected to the inner walls of the latches 11. Figure 4 The top of the movable ball 10 is compressed, causing it to engage with the inner wall of the slot 11. A magnetic disk 9 is fixedly connected to the inner wall of the sliding box 6. The outside of the needle 12 is in contact with the inner wall of the magnetic disk 9, and the needle 12 can push the magnetic disk 9 to change position.

[0035] A fixed box 5 is fixedly connected to the inner wall of the positioning box 4, which serves to limit the movement of its internal structure. The sliding box 6 is externally slidably connected to the inside of the fixed box 5, allowing it to move along the inner wall of the fixed box 5. A spring 7 is fixedly connected to the top of the magnetic disk 9, and the positional change of the magnetic disk 9 causes the spring 7 to deform. The other end of the spring 7 is fixedly connected to the inner wall of the positioning box 4, thus fixing the position of the positioning box 4 relative to the other end of the spring 7. A knitting head 18 is installed at the bottom of the moving column 3, and the knitting head 18 performs knitting operations.

[0036] Reference Figure 1 , Figure 2 and Figure 5 The needle body 1 is externally fixedly connected to a component for flattening and stretching the knitted fabric during knitting. The stretching component includes a movable column 3, the top of which is fixedly connected to the bottom of the needle body 1. The positional change of the movable column 3 can cause the needle body 1 to move in position. The movable column 3 is externally fixedly connected to a fixing ring 13, and the positional change of the movable column 3 can cause the fixing ring 13 to move in position.

[0037] The fixed ring 13 has a positioning groove 16 inside, and multiple springs 14 are fixedly connected to the inner wall of the positioning groove 16 (as shown in the attached figure). Figure 5The fixing ring 13 has a function of fixing the other end of multiple springs 14. Multiple flattening rods 15 are slidably connected to the inner wall of the fixing ring 13. The inner wall of the flattening rod 15 is provided with a slot 17. The other end of the spring 14 is fixedly connected to the inner wall of the slot 17, so that when the position of the flattening rod 15 changes, the spring 14 can deform. The reset of the spring 14 can drive the flattening rod 15 to flatten the knitted fabric.

[0038] Working principle: Connecting column 2 can fix the position of the knitting machine head. Connecting column 2 drives the external rod 8 to move, so that the external rod 8 can slide inside the positioning box 4. The external rod 8 drives the needle 12 to move, so that the two movable balls 10 are locked into the inner wall of the two slots 11. The position change of the movable balls 10 drives the magnetic disk 9 to move, so that the spring 7 deforms. When disassembling, the external magnetic structure is needed to move the magnetic disk 9, so that the magnetic disk 9 drives the sliding box 6 to move, so that the movable balls 10 are disengaged, and the needle 12 can be taken out. When the needle is knitting, its top is magnetically locked with a detachable connection structure, which facilitates the quick installation and replacement of the needle, improves production efficiency, and the connection is stable, which can ensure the stability of the needle during knitting, reduce loosening and deviation, and ensure the quality of the fabric. At the same time, this structure is easy to disassemble, clean and maintain, which is conducive to keeping the equipment clean and operating normally.

[0039] When the needle head structure is in operation, it enables the movable column 3 to move. The positional change of the movable column 3 drives the fixed ring 13 to move, which in turn drives multiple springs 14 to move. When the fixed ring 13 moves to different positions, it enables the flattening rod 15 to flatten the knitted fabric. This causes the flattening rod 15 to move in the opposite direction, causing the springs 14 to deform. When the springs 14 return to their original position, they drive the flattening rod 15 to continue flattening the knitted fabric. When the needle head is knitting, it flattens the surrounding area, ensuring that the yarn is evenly distributed, making the fabric structure tight and flat, reducing holes and defects, improving the strength and abrasion resistance of the fabric, making the fabric surface smoother, improving the appearance quality of the fabric, and effectively controlling the density and thickness of the fabric to meet different design requirements.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
