Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figure 1-5 The utility model provides a technical solution: a bobbin assembly with an adjustment function, comprising: a connecting tube 1 and a bobbin rod 2, wherein a connecting shaft is fixed to the left side of the connecting tube 1; the connecting tube 1 can be connected and fixed with other connecting components through connecting components, and the bobbin rod 2 is arranged at the right side of the connecting tube 1, and is used to carry the bobbin, wherein the connecting tube 1 and the bobbin rod 2 are both hollow;

[0020] A bobbin assembly with an adjustable function also includes a limiting structure 3 disposed within a bobbin rod 2 and configured to limit the bobbin. The limiting structure 3 includes a notch 38 formed on one side of the bobbin rod 2, two upper and lower fixed shafts 32 fixed to one side of the bobbin rod 2, and a baffle 31 pivoted within the bobbin rod 2 via the fixed shafts 32, with the baffle 31 rotating about the fixed shafts 32. The limiting structure 3 also includes a mounting plate 36 fixed to the top of the bobbin rod 2, away from the fixed shafts 32. A gap exists between the bottom of the mounting plate 36 and the inner wall of the bobbin rod 2 to allow a power cord to pass through. A micro-cylinder 35 is mounted on one side of the mounting plate 36, a connecting block 37 fixed to the output end of the micro-cylinder 35, a hinge block 34 between the baffles 31, and a connecting rod 33 between the baffle 31 and the hinge block 34. Start the micro cylinder 35. When the micro cylinder 35 is expanded, it pushes the connecting block 37, and pushes the connecting rod 33 with the cooperation of the hinge block 34. However, during the pushing process of the connecting rod 33, the baffle 31 is rotated and adjusted within 90 degrees with the fixed axis 32 through the cooperation. Conversely, when the micro cylinder 35 is retracted, the hinge block 34 rotates to a vertical state. When the baffle 31 is in a vertical state, the baffle 31 and the yarn bobbin rod 2 are in a vertical state, so that the yarn bobbin is limited and fixed. When the baffle 31 is in a horizontal state, the yarn bobbin can be put on the yarn bobbin rod 2 or removed from the yarn bobbin rod 2.

[0021] A bobbin assembly with an adjustment function also includes: an adjustment structure 4, the adjustment structure 4 is arranged between the bobbin rod 2 and the connecting tube 1, and the adjustment structure 4 is used to adjust the sum of the lengths of the connecting tube 1 and the bobbin rod 2 according to the bobbin. The adjustment structure 4 includes a first chute 44 opened on one side of the bottom of the connecting tube 1 and a first guide slider 43 fixed to the bottom of the bobbin rod 2, and the first guide slider 43 extends to the bottom of the connecting tube 1 through the first chute 44. The adjustment structure 4 also includes a fixed plate 41 fixed to one side of the bottom of the connecting tube 1, and an electric push rod 42 installed between the first guide slider 43 and the fixed plate 41. The adjustment structure 4 also includes a second chute 45 opened in the connecting tube 1 at one end away from the first chute 44, and a second guide slider 46 fixed to the top of the bobbin rod 2, and the top of the second guide slider 46 extends to the inside of the second chute 45. The first guide slider 43 is formed by the electric push rod 42 at the bottom of the connecting tube 1 and cooperates with the first slide groove 44 to form a sliding structure with the connecting tube 1, so that the position of the first guide slider 43 can be reasonably adjusted; when the electric push rod 42 is started, the first guide slider 43 can be pushed to the right side of the connecting tube 1 during the process of the electric push rod 42 starting and expanding, thereby increasing the length between the connecting tube 1 and the yarn bobbin rod 2. Conversely, when the electric push rod 42 is retracted, the first guide slider 43 is away from one side of the yarn bobbin rod 2, thereby reducing the distance between the connecting tube 1 and the yarn bobbin rod 2, so through the above description, the bobbin assembly can be reasonably adjusted according to the bobbin to be assembled, thereby increasing the applicability of the bobbin assembly to the bobbin, and also improving the stability of the assembled bobbin; the second guide slider 46 slides along the second slide groove 45, and with the cooperation of the first guide slider 43 and the first slide groove 44, the stability of the left and right movement of the bobbin rod 2 is improved, and at the same time, the limiting and guiding functions between the bobbin rod 2 and the connecting tube 1 are also realized; the above-mentioned electric push rod 42 and micro cylinder 35 are both existing technologies and will not be described in detail here.

[0022] Working principle: For this type of yarn tube assembly with adjustment function, the baffle 31 is first pushed to a horizontal state with the yarn bobbin rod 2 through the contraction of the micro-cylinder 35, the electric push rod 42 is started, and the electric push rod 42 is expanded to push the first guide slider 43 to one side of the connecting tube 1, and the length of the connecting tube 1 and the yarn bobbin rod 2 is adjusted to a length suitable for the yarn bobbin, and then the yarn bobbin is put on the yarn bobbin rod 2, and the micro-cylinder 35 is started. When the micro-cylinder 35 is expanded, the baffle 31 and the yarn bobbin rod 2 are in a vertical state. At this time, the connecting tube 1 and the baffle 31 clamp and fix the yarn bobbin. When disassembling, first start the micro-cylinder 35 to make the baffle 31 and the yarn bobbin rod 2 in a horizontal state, so as to facilitate the removal of the yarn bobbin set on the yarn bobbin rod 2, thereby reducing the time for fixing the yarn bobbin.
