Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0027] Refer to Figures 1-4 , a yarn replacement device for a double-sided rib knitting machine, including a frame body 1. The frame body 1 includes several groups of yarn storage bins 101. An elastic adjustment mechanism 2 is provided inside each of the several groups of yarn storage bins 101. A yarn release hole 3 is opened on the front surface of the yarn storage bin 101. Several groups of yarn rolls 4 are placed above the elastic adjustment mechanism 2. Elastic clamping mechanisms 5 are provided on both sides of the several groups of yarn rolls 4 on the inner wall of the yarn storage bin 101. The elastic clamping mechanism 5 includes several groups of second springs 501. The several groups of second springs 501 are all installed on the inner wall of the yarn storage bin 101. A C-shaped frame 502 is fixedly installed on the side of the several groups of second springs 501 away from the yarn storage bin 101. Several groups of rotating seats 503 are fixedly installed on one side of the C-shaped frame 502, and the several groups of rotating seats 503 are arranged in two columns opposite to each other. A rotating shaft 504 is rotatably connected between two groups of opposite rotating seats 503. A rotating roller 505 is fixedly connected to the outer surface of the rotating shaft 504. The outer surface of the yarn roll 4 is in rolling contact with the several groups of rotating rollers 505 on both sides; The elastic adjustment mechanism 2 includes a spring 201. The spring 201 is installed inside the yarn storage bin 101. A base plate 202 is installed at the top of the spring 201. The width of the base plate 202 is smaller than the diameter of the yarn roll 4.

[0028] The yarn roll 4 is placed into the yarn storage bin 101 through the yarn feeding hole 3. Under the elastic action of the second spring 501, the rotating rollers 505 contact both sides of the yarn roll 4 and clamp the yarn roll 4. At the same time, as multiple groups of yarn rolls 4 are placed, the elastic adjustment mechanism 2 is automatically compressed. During the downward movement of the yarn roll 4, the rotating rollers 505 are driven to rotate. Since the rotating rollers 505 are in rolling contact with the outer surface of the yarn roll 4, friction can be reduced, which is beneficial for clamping yarn rolls 4 of different sizes, can well meet the placement of yarns of different sizes, and can also well protect the outer surface of the yarn roll 4 from damage. As the yarn roll 4 is taken out and used, the weight above the backing plate 202 gradually decreases, and the spring 201 pushes the backing plate 202 to rise, so that the yarn roll 4 inside the yarn storage bin 101 is maintained at a height suitable for the yarn feeding hole 3, facilitating the staff to take out the yarn roll 4 from the yarn feeding hole 3 and being beneficial for the continuity of the supply of the yarn roll 4.

[0029] Refer to Figures 2-4 As shown in the figure, a height adjustment mechanism 6 is provided at the bottom of the frame body 1. The height adjustment mechanism 6 includes a support plate 601. The support plate 601 is located below the frame body 1. Two hydraulic rods 602 are fixedly installed at the top end of the support plate 601, and the telescopic ends of the two hydraulic rods 602 are installed at the bottom end of the frame body 1; four universal wheels 8 are rotatably connected to the bottom end of the support plate 601; two rectangular blocks 9 are fixedly installed on both sides of the support plate 601, and a screw rod 10 is threadedly connected inside the rectangular block 9, and an anti-slip block 11 is fixedly installed at the bottom end of the screw rod 10;

[0030] By automatically telescoping the two hydraulic rods 602 to adjust the height of the frame body 1, it is beneficial to adjust the yarn feeding hole 3 to a position suitable for the staff to take the yarn roll 4 according to the height of the staff, improving the practicality during use; through the universal wheels 8, the overall movement of the device is facilitated, which is beneficial for moving this device labor-saving; by rotating the screw rod 10, the anti-slip block 11 is made to contact the ground, increasing the stability of the device in the working state.

[0031] Refer to Figure 2 As shown in the figure, a pressure sensor is fixedly installed inside the backing plate 202, and a warning light 7 is fixedly installed on the front surface of the yarn storage bin 101. The warning light 7 is electrically connected to the pressure sensor; by monitoring the weight change of the yarn roll through the pressure sensor installed inside the backing plate 202, when the yarn roll 4 is about to be used up, the sensor sends a signal to light up the warning light 7 installed on the front surface of the yarn storage bin, which is beneficial for timely reminding the operator to replenish the yarn roll 4 in time, avoiding production interruption and improving production efficiency.

[0032] Working principle: The yarn roll 4 is placed into the yarn storage bin 101 through the yarn releasing hole 3. The rotating roller 505 contacts both sides of the yarn roll 4 under the elastic action of the second spring 501 to clamp the yarn roll 4. At the same time, as multiple groups of yarn rolls 4 are placed, the elastic adjustment mechanism 2 is automatically compressed. During the downward movement of the yarn roll 4, the rotating roller 505 is driven to rotate. Since the rotating roller 505 rolls on the outer surface of the yarn roll 4, friction can be reduced, which is beneficial to clamping yarn rolls 4 of different sizes, can well meet the placement of yarns of different sizes, and can well protect the outer surface of the yarn roll 4 from damage. The height of the frame 1 is adjusted by the automatic expansion and contraction of two hydraulic rods 602, which is beneficial to adjusting the yarn releasing hole 3 to a position suitable for the operator to take the yarn roll 4 according to the height of the operator, improving the practicability during use;

[0033] Among them, as the yarn roll 4 is taken out and used, the weight above the cushion plate 202 gradually decreases, and the spring 201 pushes the cushion plate 202 to rise, so that the yarn roll 4 inside the yarn storage bin 101 is kept at a height suitable for the yarn releasing hole 3, facilitating the operator to take out the yarn roll 4 from the yarn releasing hole 3, which is beneficial to the continuity of the supply of the yarn roll 4. The overall movement of the device is facilitated by the universal wheels 8, which is beneficial to moving this device labor-saving;

[0034] At the same time, the weight change of the yarn roll is monitored by the pressure sensor installed inside the cushion plate 202. When the yarn roll 4 is about to be used up, the sensor sends a signal to light up the warning lamp 7 installed on the front surface of the yarn storage bin, which is beneficial to timely reminding the operator to replenish the yarn roll 4 in time, avoiding production interruption and improving production efficiency;

[0035] In addition, by rotating the screw rod 10, the anti-slip block 11 is made to contact the ground, increasing the stability of the device in the working state.

[0036] The above are only the preferred embodiments of the present application and are not used to limit the present application.
