Description

Technical Field

[0001] This utility model relates to the field of covering yarn machine technology, and in particular to a yarn bobbin fixing buckle structure for a covering yarn machine. Background Technology

[0002] A covering yarn machine is a specialized textile equipment used to manufacture spandex covered yarn (an elastic yarn with spandex as the core yarn and outer fibers wound around it). Its core function is to evenly wind the outer fibers onto the core yarn using mechanical or aerodynamic principles, meeting the elasticity and surface properties requirements of different fabrics. The yarn bobbin is one of the main components of the covering yarn machine, and current technology often uses a fixed snap-fit ​​structure for its installation.

[0003] However, the existing yarn bobbin fixing buckle structure cannot be effectively extended during use, which makes it unable to adapt to fixing yarn bobbins with different apertures, reducing its applicability and efficiency. Furthermore, it cannot move the right side of the insertion rod while expanding, thus only allowing for unidirectional locking and reducing its stability. Therefore, we propose a yarn bobbin fixing buckle structure for a covering yarn machine. Utility Model Content

[0004] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to provide a yarn bobbin fixing buckle structure for a covering yarn machine, which can be effectively extended so that it can adapt to the fixing of yarn bobbins with different apertures, thereby improving its applicability and efficiency. Moreover, while expanding, it can drive the right side of the insertion rod to move, thereby enabling multi-directional locking and improving its stability.

[0005] To achieve the above objectives, a yarn bobbin fixing buckle structure for a covering yarn machine is provided, comprising: a tube body, the left and right sides of which are respectively closed, and circular blocks are connected through the left and right sides of the tube body; a rotating rod is sleeved inside the tube body, and the circular blocks have through holes matching the rotating rod; the left and right ends of the rotating rod extend out of the tube body through the through holes; circular tubes are respectively provided on the left and right sides of the tube body, and the rotating rod is sleeved inside the circular tubes through bearings; elliptical rings are respectively sleeved on the rotating rod near the left and right sides; first contact wheels are respectively attached to the top and bottom of the elliptical rings; and a bracket is movably connected to the outside of the first contact wheels; a vertical rod is bolted to the side of the bracket away from the first contact wheels, and an arc-shaped plate is bolted to the side of the vertical rod away from the bracket.

[0006] According to the yarn bobbin fixing buckle structure of the covered yarn machine, the top and bottom of the inner cavity of the tube are respectively provided with movable grooves that match the arc plate, and the side of the arc plate that is far away from the vertical rod is connected to the locking block by bolts.

[0007] According to the yarn bobbin fixing buckle structure of the covered yarn machine, a sliding plate is slidably connected to the two opposing sides of the circular blocks near the top and bottom, and a right-angled trapezoidal block is bolted to the side of the sliding plate away from the circular blocks. A connecting rod is bolted to the side of the right-angled trapezoidal block away from the circular blocks near the top and bottom, and the end of the connecting rod away from the right-angled trapezoidal block is bolted to the side wall of the vertical rod.

[0008] According to the yarn bobbin fixing buckle structure of the covered yarn machine, the two circular blocks are respectively connected to the top and bottom sides by bolts to the limiting tubes, and the limiting tubes are provided with insert rods. The circular blocks are provided with through holes, and the end of the insert rod that is away from the right-angled trapezoidal block extends out of the tube body through the through hole. The side of the insert rod that is opposite to the right-angled trapezoidal block is movably connected to the second contact wheel through a rotating shaft and bearing, and the insert rod is attached to the inclined surface of the right-angled trapezoidal block.

[0009] According to the yarn bobbin fixing buckle structure of the covered yarn machine, a number of evenly distributed crossbars are bolted to the side of the round tube opposite to the round block, and the ends of the crossbars that are far away from the round tube are bolted to the side wall of the round block.

[0011] According to the yarn bobbin fixing buckle structure of the covering yarn machine, the sliding plate is connected to a slider by bolts on the side away from the right-angled trapezoidal block, and a groove matching the slider is opened on the side wall of the circular block.

[0012] The above solution has at least one of the following beneficial effects: This technical solution, through the cooperation between components such as the rotating rod, the elliptical ring, the right-angled trapezoidal block and the second contact wheel, enables it to be effectively extended, thereby adapting to the fixing of yarn bobbins with different apertures, improving its applicability and efficiency.

Detailed Implementation

[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0023] Reference Figures 1 to 5 This utility model discloses a yarn bobbin fixing buckle structure for a covering yarn machine, comprising: a tube body 1, with the left and right sides of the tube body 1 being closed off, and circular blocks 2 being connected through the left and right sides of the tube body 1; a rotating rod 9 being sleeved inside the tube body 1, and through holes matching the rotating rod 9 being opened on the circular blocks 2; the left and right ends of the rotating rod 9 extending out of the tube body 1 through the through holes; circular tubes 3 being provided on the left and right sides of the tube body 1, and the rotating rod 9 being sleeved inside the circular tubes 3 by bearings; elliptical rings 12 being sleeved on the rotating rod 9 near the left and right sides; first contact wheels 13 being attached to the top and bottom of the elliptical rings 12, and a bracket 11 being movably connected to the outside of the first contact wheels 13; a vertical rod 10 being bolted to the side of the bracket 11 away from the first contact wheels 13, and an arc-shaped plate 6 being bolted to the side of the vertical rod 10 away from the bracket 11.

[0024] The inner cavity of tube 1 has movable grooves 20 at the top and bottom near the left and right sides, matching the arc-shaped plate 6. A locking block 7 is bolted to the side of the arc-shaped plate 6 away from the vertical rod 10. Sliding plates 18 are slidably connected to the opposite sides of the two circular blocks 2 near the top and bottom, respectively. A slider is bolted to the side of the sliding plate 18 away from the right-angled trapezoidal block 14. A groove matching the slider is provided on the sidewall of the circular block 2. A right-angled trapezoidal block 14 is bolted to the side of the sliding plate 18 away from the circular block 2. A connecting rod 17 is bolted to the sidewall of the right-angled trapezoidal block 14 near the top and bottom, respectively. The end of the connecting rod 17 away from the right-angled trapezoidal block 14 is bolted to the sidewall of the vertical rod 10. This structure allows for effective extension, enabling the fixing of yarn bobbins with different apertures, thus improving its applicability and efficiency.

[0025] Two circular blocks 2 are bolted to limit tubes 15 near their top and bottom sides, with insert rods 5 passing through them. A through hole is formed on each circular block 2, and the end of the insert rod 5, away from the right-angled trapezoidal block 14, extends through the through hole to the outside of the tube body 1. A second contact wheel 19 is movably connected to the side of the insert rod 5 opposite to the right-angled trapezoidal block 14 via a shaft and bearing, and the insert rod 5 is attached to the inclined surface of the right-angled trapezoidal block 14. A circular tube 3 is bolted to a number of evenly distributed horizontal bars 8 on the side opposite to the circular blocks 2, with the ends of the horizontal bars 8 bolted to the sidewall of the circular block 2. A connecting tube 4 is bolted to the side of the circular tube 3 away from the horizontal bars 8, and cross grooves 16 are formed at both ends of the rotating rod 9. This structure allows the insert rod 5 to move to the right side while expanding, enabling multi-directional engagement and improving its stability.

[0026] Working principle: In use, this technical solution first drives the rotating rod 9 to rotate through the cross groove 16, causing the rotating rod 9 to rotate within the threaded hole on the circular block 2. The rotating rod 9 drives the elliptical ring 12 to rotate, causing the elliptical ring 12 to press against the first contact wheel 13 and the bracket 11, which in turn causes the vertical rod 10, the arc plate 6, and the snap-fit ​​block 7 to move away from or towards each other, allowing for effective extension. This enables the fixing of yarn bobbins with different apertures, improving its applicability and efficiency. At the same time, the vertical rod 10 moves through the right-angled trapezoidal block 14 and presses against the second contact wheel 19. The second contact wheel 19 drives the insertion rod 5 to slide within the limiting tube 15, causing the insertion rod 5 to extend outward or retract inward. This expansion also drives the movement of the right side of the insertion rod 5, enabling multi-directional snap-fit ​​and improving its stability.

[0027] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
