Technical Field

[0001] This utility model relates to the field of textile equipment technology, specifically a knitting machine head. Background Technology

[0002] The knitting head is the core component of a knitting machine. The knitting machine uses multiple heads on the needle bed in conjunction with a yarn feeder, circulator, and tensioner to complete the weaving process through reciprocating motion. During this process, the needles need to move up and down within the needle grooves to complete the knitting action.

[0003] The existing knitting machine head includes a machine housing, inside which a needle cylinder is installed. Several needle grooves are opened on the side wall of the needle cylinder, and knitting needles are slidably connected in the needle grooves. A cam system is installed inside the machine housing. The cam device is similar to a set of planar cams. The needle feet can enter the grooves of the cams. Moving the cam forces the knitting needles to make regular up-and-down movements in the needle grooves, and the knitting is completed by the action of the needle hook and the needle tongue.

[0004] The existing knitting needles are fixedly installed inside the machine housing. Due to the limitation of the cam system, the cam system needs to be removed first during disassembly, which is inconvenient and makes the operation of replacing knitting needles more troublesome, time-consuming and laborious.

[0011] As a further feature of this invention, the knitting needle is made of stainless steel.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] When it is necessary to replace the knitting needle, this utility model simply pushes the movable cam upward along the length of the needle cylinder, moving it away from the fixed cam, thereby expanding the groove until the restriction on the needle foot is released. This allows the needle cylinder to be rotated until the knitting needle to be replaced moves to the release groove position. At this time, the release groove is aligned and connected with the needle groove where the knitting needle is located. Simply pinch the part of the knitting needle protruding from the needle cylinder and pull it outward to allow the needle foot to come out through the release groove, thus removing the old knitting needle from the needle cylinder. Then, insert the new knitting needle into the needle groove, so that the needle foot is locked into the groove from the release groove. Then, push the movable cam downward along the length of the needle cylinder, moving it closer to the fixed cam, so that the groove returns to its original shape, thereby restricting the needle foot inside the groove and realizing the replacement of the knitting needle. The operation is relatively convenient and simple, saving time and effort. Attached Figure Description

[0019] 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.

[0020] Please see Figure 1-4 As shown, a knitting machine head includes a housing 1, inside which a needle cylinder 2 is disposed. A connecting tube 15 is disposed on the needle cylinder 2, penetrating the housing 1. Rotating the connecting tube 15 drives the needle cylinder 2 to rotate, making operation convenient and labor-saving. Several needle grooves 3 are formed on the side wall of the needle cylinder 2, and knitting needles 4 are slidably connected in the needle grooves 3. The knitting needles 4 are made of stainless steel, which has high strength and hardness, is not easy to rust, and has good durability. The knitting needles 4 include needle feet 5. A triangular mechanism is provided on the needle cylinder 2, which includes a fixed cam 6 and a movable cam 7 arranged opposite to each other. The fixed cam 6 is rotatably connected to the needle cylinder 2, and the movable cam 7 is slidably connected to the needle cylinder 2. A groove 8 is formed between the fixed cam 6 and the movable cam 7. The needle feet 5 are used to engage with the groove 8 and move within the groove 8. A release groove 9 is provided on the fixed cam 6 for the needle feet 5 to disengage. When it is necessary to replace the knitting needle 4, simply push the movable cam 7 upward along the length of the needle cylinder 2, moving it away from the fixed cam 6, thereby expanding the channel 8 until the restriction on the needle foot 5 is released. This allows the needle cylinder 2 to rotate until the knitting needle 4 to be replaced moves to the release groove 9 position. At this time, the release groove 9 is aligned and connected with the needle groove 3 where the knitting needle 4 is located. Simply pinch the part of the knitting needle 4 that is exposed in the needle cylinder 2 and pull it outward to allow the needle foot 5 to come out through the release groove 9, thus removing the old knitting needle 4 from the needle cylinder 2. Then, insert the new knitting needle 4 into the needle groove 3, so that the needle foot 5 is inserted from the release groove 9 into the channel 8. Then push the movable cam 7 downward along the length of the needle cylinder 2, moving it closer to the fixed cam 6, so that the channel 8 returns to its original shape, thereby restricting the needle foot 5 inside the channel 8, realizing the replacement of the knitting needle 4.

A connecting ring 11 is provided inside the housing 1, and several elastic elements 12 are connected between the connecting ring 11 and the cylinder 10. The elastic elements 12 are springs. When it is necessary to remove the knitting needle 4, the cylinder 10 can be pushed upward to slide, so that the movable cam 7 slides upward along the length direction of the needle cylinder 2, thereby squeezing the elastic elements 12, causing the elastic elements 12 to undergo compression deformation. When the knitting needle 4 is being replaced... After completion, simply release the cylinder 10, and the elastic element 12 will automatically extend and return to its original shape, thereby pushing the cylinder 10 to automatically reset. The operation is relatively convenient. Several sliding grooves 13 are provided on the side wall of the housing 1, and several push blocks 14 that pass through the sliding grooves 13 are provided on the outer side wall of the cylinder 10. By pushing the push blocks 14 to slide along the sliding grooves 13, the cylinder 10 can be pushed to slide inside the housing 1. The limiting of the push blocks 14 by the sliding grooves 13 makes the operation of pushing the cylinder 10 smoother and less prone to jamming, thus making the operation of changing the knitting needles 4 easier.
