[0018] The straight eye needle 6 and the crochet hook 7 operate on the vertical section of the fabric 15. The specific working principle is the same as that of existing crochet machines. This will not be described in detail here. The innovation of this design lies in the fact that multiple sets of straight eye needles 6 can be adjusted individually.

[0019] Specifically, such as Figure 1 , Figure 3 , Figure 4 As shown, this device also includes two sets of needle beds 3 for mounting straight needles 6 and hook needles 7. The straight needles 6 and hook needles 7 are arranged one in front of the other, and the two sets of needle beds 3 are located on the front and back sides of the fabric 15. Each set of needle beds 3 has several needles. The frame 1 is equipped with an adjustment device that can adjust each needle bed 3 individually. The adjustment device includes several sets of slide rails 2 and adjustment mechanisms 4. The slide rails 2 are fixed on the frame 1 and are arranged horizontally and longitudinally.

Straight needles 6 can be installed on each needle bed 3 at any lateral position. The number of needle beds 3 is not limited and can be set according to the pattern requirements. Theoretically, as long as the frame 1 can accommodate them, the number of needle beds 3 can be unlimited.

[0020] Needle seats 5 are installed regularly on several rows of needle beds 3 according to the knitting pattern. During the knitting process, the straight needles 6 on each group of needle beds 3 can be moved laterally independently under the control of the adjustment mechanism 4. Compared with the existing single needle bed 3 knitting a single strip of fabric, multiple needle beds 3 can be independently adjusted to knit more complex patterns.

[0021] like Figure 4 As shown, this device also includes a needle holder 5. A straight eye needle 6 or a hook needle 7 is mounted on the front end of the needle holder 5. The needle bed 3 has horizontally spaced slots 31, with a raised strip 32 formed between adjacent slots 31.

The tail of the needle holder 5 has a long, narrow groove through which a fixing bolt 34 passes, allowing adjustment of the needle holder 5's front and rear positions. The tail of the needle holder 5 is fixed to the screw hole 33 by the fixing bolt 34. The straight eye needle 6 or hook needle 7 can be installed at any horizontal position on the needle bed 3, with the number of straight eye needles 6 or hook needles 7 installed depending on requirements.

[0022] By setting the slot 31, the retaining strip at the bottom of the needle holder 5 can be locked in the slot 31 to prevent the needle holder 5 from becoming loose.

[0023] like Figure 3 As shown, the adjusting mechanism 4 includes a support base 41, a lead screw 42, a nut 43 threaded onto the lead screw 42, a connecting rod 45, and a motor 46. The support base 41 is fixed to the frame 1. Both ends of the lead screw 42 are pivotally connected to the support base 41 via bearing seats. The lead screw 42 is arranged along the length direction of the slide rail 2. The support base 41 is provided with a guide groove 44 for the nut 43 to slide along the length direction of the lead screw 42. Both ends of the connecting rod 45 are hinged to the nut 43 and the needle bed 3, respectively. The motor 46 is used to drive the lead screw 42 to rotate.

[0024] The adjustment mechanism 4 also includes a pair of pulleys 47, which are connected to the motor output shaft and the lead screw 42 respectively, and are connected by belt 48.

[0025] During adjustment, the nut 43 slides through the connecting rod 45 to pull the needle bed 3 to slide on the slide rail 2, thereby achieving lateral adjustment.

[0026] The device also includes a wire guide for guiding the wire 16 into the eye needle 6. The wire guide includes a hanging plate 9 and several guide tubes 8. The hanging plate 9 can be fixed on the frame 1 or an adjustment mechanism 4 can be provided. A transverse guide rail is provided on the frame 1. The hanging plate 9 is slidably adapted to the guide rail. The adjustment mechanism 4 is used to adjust the transverse movement of the hanging plate 9 so that the guide tubes 8 on the hanging plate 9 can move transversely with the transverse movement of the eye needle 6. Several guide tubes 8 are hung on the hanging plate 9 according to the position of the eye needle 6 by hooks 81.

[0027] like Figure 4As shown, the hanging plate 9 has horizontally spaced positioning grooves 91 for accommodating the hooks 81. The hooks 81 are prevented from swinging left and right when they are hung in the positioning grooves 91.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
