[0001] The invention relates to the technical field of textile equipment, in particular to a double-sided plush knitting machine. Background Art

[0002] Because the yarn fiber of plush fabric is fine and elastic, the surface of the fabric will wrinkle and the edge will curl when the plush fabric is rolled up, which affects the appearance. Therefore, in the process of plush fabric production by plush knitting machine, it is necessary to set a cloth guide rod to flatten the plush fabric.

[0003] refer to Figure 1 When the plush fabric (not shown in the figure) is transported, it is flattened after passing through the bottom of the cloth guide rod 1' and then transmitted to the subsequent winding mechanism for winding. However, in actual use, the cloth guide rod 1' contacts and scratches the plush fabric, which will damage the yarn fibers and even cause hair loss. Summary of the invention

[0004] Therefore, in view of the above-mentioned problems, the present invention proposes a double-sided plush knitting machine, which can flatten the plush fabric without causing damage to the plush fabric.

[0030] The present invention will now be further described with reference to the accompanying drawings and specific implementation methods.

[0031] refer to Figures 2 to 9 The present embodiment provides a double-sided plush knitting machine, comprising a knitting machine support frame 1, an upper needle cylinder 2 arranged on the knitting machine support frame 1, a lower needle cylinder 3 arranged at intervals outside the upper needle cylinder 2, a winding mechanism 4 arranged below the knitting machine support frame 1, a lifting rod 5 arranged in the knitting machine support frame 1, a connecting plate 6 arranged on the bottom surface of the lifting rod 5, a plurality of sliding grooves 7 arranged in the connecting plate 6 at equal angles, a support arm slidingly arranged in the sliding groove 7, a guide structure arranged on a side of the support arm away from the connecting plate 6, a protruding column 8 arranged in the middle of the connecting plate 6, an adjusting plate 9 rotatably arranged outside the protruding column 8, a plurality of guide grooves 10 arranged in the adjusting plate 9 at equal angles, a sliding column 11 arranged at the top of the support arm and slidably connected to the guide groove 10, a driving mechanism arranged on one side of the connecting plate 6 and used for driving the adjusting plate 9 to rotate, and a driving device 12 for driving a built-in roller (not shown in the figure) of the winding mechanism 4 to rotate.

[0032] The support arm includes a first support arm 131, a second support arm 132, a third support arm 133 and a fourth support arm 134, the guide structure includes a first guide rod 141 arranged at one side of the first support arm 131, a second guide rod 142 arranged at one side of the second support arm 132, a third guide rod 143 arranged at one side of the third support arm 133 and a fourth guide rod 144 arranged at one side of the fourth support arm 134, the length of the first support arm 131 is greater than the length of the third support arm 133, the length of the first support arm 131 is the same as that of the second support arm 132, the length of the third support arm 133 is the same as that of the fourth support arm 134, the first guide rod 141 and the second guide rod 142 are in the shape of a V-shaped arc, the V-shaped arc has a circular arc transition, the cross-sectional shape of the third guide rod 143 and the fourth guide rod 144 is a circular surface 145, and the first guide rod 141, the second guide rod 142, the third guide rod 143 and the fourth guide rod 144 surround to form an ellipse.

[0033] Through the setting of the guide structure, when the winding mechanism 4 winds up the plush fabric, the plush fabric will pass through the guide structure on one side of the support arm. Since the first guide rod 141, the second guide rod 142, the third guide rod 143 and the fourth guide rod 144 are elliptical in shape and the winding mechanism 4 is cylindrical, the plush fabric passes through the guide structure to reach the winding mechanism 4 more smoothly. The plush fabric is subjected to more even force when contacting the first guide rod 141, the second guide rod 142, the third guide rod 143 and the fourth guide rod 144, and has less deformation when passing through the guide structure. Moreover, the first guide rod 141 and the second guide rod 142 are in a V-shaped arc shape, so the interwoven yarns in the plush fabric passing through will not be stretched, and the plush fabric after winding is smoother.

[0034] The included angle between the center line 15 between the upper needle cylinder 2 and the lower needle cylinder 3 and the guide structure is 110°-130°. When the included angle between the guide structure and the center line 15 is 125°, the contact area with the plush fabric is small, and the plush fabric is not easily stretched outward, which is the best usage state.

[0035] refer to Figure 6 Since the cross-sectional shape of the first guide rod 141, the second guide rod 142, the third guide rod 143 or the fourth guide rod 144 is a round surface 145, when any cross-sectional surface of the first guide rod 141, the second guide rod 142, the third guide rod 143 or the fourth guide rod 144 contacts the plush fabric, the round surface 145 will always contact the plush fabric, and the contact is smoother than that of a square or sheet-shaped guide rod. Even if the angle between the plush fabric and the lower needle cylinder 3 is 5°-10°, the edges and corners of the guide structure will not contact the plush fabric, thereby providing good protection for the plush fabric.

[0036] The driving mechanism includes a driven gear 161 arranged on the outside of the adjusting disk 9, a driving gear 162 rotatably arranged on the connecting disk 6 and meshing with the driven gear 161, a partition 163 spaced above the connecting disk 6, and a first motor 164 arranged on the partition 163, and the first motor 164 is connected to the driving gear 162.

[0037] The setting of the driving mechanism, when it is needed to be used on plush knitting machines of different sizes, controls the first motor 164 to rotate through the external control panel, the first motor 164 drives the driving gear 162 to rotate, the driving gear 162 drives the driven gear 161 and the adjusting disk 9 to rotate, because the guide groove 10 gradually approaches the protruding column 8 from one side to the other side, during the rotation of the adjusting disk 9, the guide groove 10 will drive the support arm to gradually move outward through the protruding column 8, the first support arm 131, the second support arm 132, the third support arm 133 and the fourth support arm 134 will move outward at the same time, and at the same time drive the first guide rod 141, the second guide rod 142, the third guide rod 143 and the fourth guide rod 144 to move outward, and the distance of each guide structure is adjusted by the first motor 164, so as to facilitate the use with plush knitting machines of different sizes.

[0038] refer to Figure 4 The middle dotted line, the V-shaped arc angle is 73°-83°, and there is an arc transition between the angles. The arc transition has a small curvature, and when it contacts the plush fabric, the contact surface is close to a spherical surface. When it contacts the plush fabric, the force is more evenly applied, and the plush fabric yarn is less likely to be stretched.

[0039] A spring 17 is provided between the first guide rod 141 and the first support arm 131 . A limiting groove 135 is provided at the connection between the first guide rod 141 and the first support arm 131 . The limiting groove 135 in the first guide rod 141 is slidably connected to the first support arm 131 .

[0040] The first support arm 131 is provided with a photoelectric sensor 18 for detecting the moving distance of the first guide rod 141. When the tension of the plush fabric is too large, the spring 17 on one side of the first guide rod 141 is compressed and moves toward the direction of the adjustment disk 9. After the photoelectric sensor 18 detects that the moving distance of the first guide rod 141 is greater than the set distance, it sends an electrical signal to the external control center. The external control center controls the first motor 164 to rotate, so that the first support arm 131, the second support arm 132, the third support arm 133 and the fourth support arm 134 move toward the center of the connecting disk 6. At the same time, the external control center reminds to prevent the plush fabric from being excessively tensile, which affects the service life of the knitting needles.

[0041] An adjusting mechanism 19 connected to the connecting plate 6 is provided at the bottom of the knitting machine support frame 1, and the adjusting mechanism 19 includes a connecting bracket 901 connected to the knitting machine support frame 1, a first connecting arm 902 rotatably arranged in the middle of the connecting bracket 901, a second motor 903 for driving the first connecting arm 902 to rotate, a circular rail 904 arranged in the middle of the connecting bracket 901 and spaced apart from the first connecting arm 902, a rotating rod 905 rotatably arranged on the circular rail 904, a square groove 906 arranged on one side of the rotating rod 905, a second connecting arm 907 rotatably arranged on the connecting bracket 901, a first guide groove 908 arranged in the second connecting arm 907, a straight rail 909 arranged on one side of the connecting bracket 901, a moving groove 910 arranged on the straight rail 909, a moving block 911 slidably arranged in the moving groove 910, a third connecting arm 912 arranged on the other side of the moving block 911, and a second guide groove 913 arranged on the third connecting arm 912.

[0042] The first connecting arm 902 is slidably connected to the square groove 906 on one side of the rotating rod 905, and the other side of the rotating rod 905 is slidably connected to the first guide groove 908. The lifting rod 5 includes an outer tube 501 fixedly connected to the connecting plate 6, and an inner tube 502 fixedly connected to the knitting machine support frame 1. The moving block 911 is connected to the bottom of the outer tube 501.

[0043] The second motor 903 drives the first connecting arm 902 to rotate, and the first connecting arm 902 drives the rotating rod 905 to rotate along the center of the circular track 904 by contacting with the square groove 906 on the rotating rod 905. After the first connecting arm 902 moves back and forth from the square groove 906 on the rotating rod 905, the rotating rod 905 drives one side of the second connecting arm 907 to swing from the top of the straight track 909 to the bottom by contacting with the first guide groove 908. Since the second connecting arm 907 is slidably connected with the second guide groove 913 in the third connecting arm 912, the moving block 911 is driven by the second connecting arm 907 to slowly slide from the top of the straight track 909 to the bottom. At the same time, the first motor 903 drives the first connecting arm 902 to rotate, and the first connecting arm 902 drives the rotating rod 905 to rotate along the center of the circular track 904. The first motor 164 drives the adjusting disk 9 to rotate through the driving gear 162 and the driven gear 161, and the first guide rod 141, the second guide rod 142, the third guide rod 143 and the fourth guide rod 144 are adjusted by the adjusting disk 9 to move to the farthest position from the adjusting disk 9, and then the first motor 164 rotates in the reverse direction, driving the first guide rod 141, the second guide rod 142, the third guide rod 143 and the fourth guide rod 144 to gradually move toward the center of the adjusting disk 9, and the elliptical shape surrounded by the first guide rod 141, the second guide rod 142, the third guide rod 143 and the fourth guide rod 144 will gradually shrink, and the plush fabric passes through the first guide rod 141, the second guide rod 142, the third guide rod 143 and the fourth guide rod 144 are guided to gradually shrink until they are rolled up by the winding mechanism 4. When the rotating rod 905 on the first connecting arm 902 moves from one side of the square groove 906 to the other side and returns to move close to the center of the circular rail 904, and then moves out, since the rotating rod 905 is close to the center of the circular rail 904, the rotating rod 905 will quickly drive the second connecting arm 907 to swing from the bottom to the top of the straight rail 909, and the moving block 911 will quickly move to the top. At the same time, the first motor 164 drives the adjusting disk 9 to rotate through the driving gear 162 and the driven gear 161, and the adjusting disk 9 is adjusted. The first guide rod 141, the second guide rod 142, the third guide rod 143 and the fourth guide rod 144 will move to the position farthest from the adjusting disk 9. After completion, the first guide rod 141, the second guide rod 142, the third guide rod 143 and the fourth guide rod 144 will shrink to the smallest shape, and then the first guide rod 141, the second guide rod 142, the third guide rod 143 and the fourth guide rod 144 will quickly move to the initial position. During the transportation process, the plush fabric will remain in contact with the center line 15, the plush fabric will be more evenly stressed when rolled up, reducing the local tension, and due to the more even stress, the plush fabric yarns will be neater, thereby improving the quality of the plush fabric.
