[0029] The following is a further explanation of this case with a specific working process.
[0030] The lower knitting needle 1 passes through this knitting unit and first reaches the flat needle selection point 511. If the flat needle selector 51 selects the jacquard piece 13, the jacquard piece 13 moves the middle needle 12, so that the middle needle butt is separated from the middle needle ascending track 31, the hook 11 does not eat the yarn, and the lower knitting needle 1 moves horizontally through this group of knitting units, forming a corresponding hairless texture on the fabric. Figure 3 shown.
[0031] If the flat needle selector 51 does not select the jacquard piece 13, the lower knitting needle 1 rises to the highest point along the middle needle rising track 31 through the middle needle butt, moves along the hook yarn descending section 41 through the hook needle butt, and / or moves along the middle needle descending track 32 through the middle needle butt, the lower knitting needle 1 descends and makes the hook needle 11 hook the fed yarn to eat the yarn.
[0032] As the movement proceeds, the lower knitting needle 1 continues to descend from the middle needle butt along the middle needle descending track 32, and first reaches the first track entry needle selection point 521. If the first track entry needle selector 52 selects the jacquard piece 13, the jacquard piece 13 moves the middle needle 12, so that the middle needle butt is separated from the middle needle descending track 32, and the lower knitting needle 1 moves horizontally. The butt of the hook 11 is placed from the first track entry port 421 and enters the first hook needle descending track 42. The lower knitting needle 1 descends along the first hook needle descending track 42, and the hook 11 pulls out a short length of yarn downward. The hook needle butt enters the first hook needle height maintaining track 45 and moves horizontally backward. Then the lower knitting needle 1 passes through the position of the cutter lifting track 21. The cutter butt moves along the cutter lifting track 21, so that the cutter 14 moves upward to cut the yarn pulled down by the hook needle 11 to form fluff. The lower knitting needle 1 passes through this group of weaving units, and a corresponding short-hair texture is formed on the fabric. The needle trajectory reference of short-hair texture knitting Figure 4 shown.
[0033] If the first track-entering needle selector 52 does not select the jacquard piece 13, the lower knitting needle 1 continues to descend from the middle needle butt along the middle needle descending track 32 to reach the second track-entering needle selection point 531. If the second track-entering needle selector 53 selects the jacquard piece 13, the jacquard piece 13 moves the middle needle 12 to make the middle needle butt leave the middle needle descending track 32, the lower knitting needle 1 moves horizontally, the butt of the crochet hook 11 is placed from the first track-entering mouth 431 and enters the second crochet hook descending track 43, the lower knitting needle 1 descends along the second crochet hook descending track 43, the crochet hook 11 pulls out a medium-length yarn downward, the crochet hook butt enters the second crochet hook height maintaining track 46 and moves horizontally backward, and then the lower knitting needle 1 passes through the position of the cutter lifting track 21, the cutter butt moves along the cutter lifting track 21 to make the cutter 14 move upward to cut the yarn pulled down by the crochet hook 11 to form fluff, and the lower knitting needle 1 passes through this group of weaving units to form a corresponding medium-wool texture on the fabric. Needle trajectory reference for medium wool texture knitting Figure 5 shown.
[0034] If the second track needle selector 43 does not select the jacquard piece 13, the lower knitting needle 1 continues to descend from the middle needle butt along the middle needle descending track 32 to the end low point, the hook needle 11 pulls the longest set length of yarn downward, and the middle needle butt moves backward along the middle needle height maintenance track 33. Then the lower knitting needle 1 passes through the position of the cutter lifting track 21, and the cutter butt moves along the cutter lifting track 21 to make the cutter move upward to cut the yarn pulled down by the hook needle 11 to form fluff. The lower knitting needle 1 passes through this group of weaving units, and a long-hair texture is formed on the fabric accordingly. The needle trajectory reference of long-hair texture knitting Figure 6 shown.
[0035] When each lower knitting needle 1 reaches the end of the knitting unit, the butt of the middle needle will pass through the reset and give way area 44, and the reset cam 6 will press into each jacquard piece 13 to reset the middle needle.
[0036] The fabric textures that can be achieved by the equipment of this application include hairless texture, short hair texture, medium hair texture, and long hair texture, and they can be mixed and woven on the fabric according to actual needs. During the upward movement of the cutter 14, the heel of the crochet hook is at a certain crochet hook height maintenance track or the heel of the middle needle is within the middle needle height maintenance track. Therefore, the crochet hook 11 will not move due to the upward movement of the cutter 14, ensuring the completion of the loop cutting action.
[0037] The above is only a specific implementation manner of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantive modification made to the present utility model using this concept shall fall within the scope of infringement of the protection scope of the present utility model.
