AI Technical Summary
The existing three-layer plush knitting machine has a problem where the third triangular track between the second and fourth triangular tracks is not continuous, causing the hook needle heel to collide when it descends to the starting point, resulting in equipment damage and shutdown.
It adopts a double-needle hook structure, including two hooks set on the hook head, combined with the first and second channel design of the triangular device. Through the needle lifting technology, the third triangular track is removed. By using the design of the first and second channels and the combination of different channels and hooks, long, medium and short plush can be knitted, avoiding the collision of the hook heel.
This ensures continuous operation of the equipment, avoids impact from the hook heel, and guarantees stable operation of the equipment.

Abstract
Claims
1. A double needle hook structure, characterized by: The device includes a cam device (3), a needle assembly, and a needle selector (5); the cam device (3) has a first channel and a second channel located above the first channel; the needle assembly includes a hook (1) and a needle plate (2), the hook (1) having a needle heel (11) that can move in the second channel, and the needle plate (2) having a plate heel (21) that can move in the first channel, the lower end of the hook (1) being hooked to the upper end of the needle plate (2) and being able to rotate relative to each other; the needle selector (5) is used to push the plate heel (21) of the needle plate (2) into or out of the first channel; The crochet hook (1) has two hooks arranged from top to bottom: a first hook (121) and a second hook (122). In the first channel, a first triangular track (31) and a fourth triangular track (34) are arranged in sequence along the forward direction. The first triangular track (31) gradually tilts upward along the forward direction, and the fourth triangular track (34) gradually tilts downward along the forward direction. The upper end of the first triangular track (31) is connected to the upper end of the fourth triangular track (34). In the second channel, a second triangular track (32) is arranged at a position corresponding to the fourth triangular track (34). The second triangular track (32) also tilts downward along the forward direction. The distance L1 between the highest and lowest positions of the fourth triangular track (34) is greater than the distance L2 between the highest and lowest positions of the second triangular track (32). The first triangular track (31) has two steps arranged from top to bottom: a first step (311) and a second step (312). The heel (21) of the needle-lifting plate (2) moves to the first step (311), and then the heel (21) moves down to the bottom along the fourth triangular track (34). The second needle hook (122) hooks the yarn for long-pile knitting. When the heel (21) of the needle-lifting plate (2) moves to the first step (311), and the needle selector (5) pushes the plate... When the heel (21) leaves the first channel, the needle heel (11) continues to move forward and descends along the second triangular track (32), and the second needle hook (122) hooks the yarn to perform medium-pile knitting; when the heel (21) of the needle plate (2) moves to the second step (312), and the needle selector (5) pushes the heel (21) to leave the first channel, the needle heel (11) continues to move forward and descends along the second triangular track (32), and the first needle hook (121) hooks the yarn to perform short-pile knitting.
2. A loop cutting machine having a double needle hook structure as claimed in claim 1, characterized in that: It also includes a frame and a cylinder (4), the cylinder (4) being mounted on the frame and rotatable around the central axis of the frame. The cylinder (4) has a vertically extending slot (41) on its wall. The knitting needle assembly is installed in the slot (41) and rotates with the cylinder (4). The triangular device is fixedly mounted on the frame and maintains a gap with the outer circumference of the cylinder (4). The knitting needle assembly also includes a jacquard piece (6), the lower end of which is rotatably connected to a lower fulcrum on the cylinder (4). 61) The upper end of the jacquard piece (6) is provided with two clamping arms (62). The lower end of the needle-lifting piece (2) is movably inserted between the two clamping arms (62). Thus, when the jacquard piece (6) rotates around the lower fulcrum (61), the two clamping arms (62) can drive the needle-lifting piece (2) to rotate around the hooking point with the hook (1), thereby driving the heel (21) to enter or leave the first channel. The needle selector (5) is fixedly installed on the frame to drive the jacquard piece (6) to rotate around the lower fulcrum (61).
3. A loop cutting machine according to claim 2, characterized in that: The second channel is provided with a fifth triangular track (35) at a position corresponding to the first triangular track (31). The fifth triangular track (35) and the second triangular track (32) are both the upper walls of the second channel, and there is a hollow part (36) between the fifth triangular track (35) and the second triangular track (32).
