Description

Technical Field

[0001] This utility model relates to the field of knitting technology, and in particular to a yarn holder for preventing yarn breakage on a computerized flat knitting machine. Background Technology

[0002] A yarn bobbin is a device used for winding and storing spinning yarn. It is also needed to assist in the unwinding of yarn during the operation of a textile machine, and is therefore widely used in textile production and processing facilities.

[0003] When a computerized flat knitting machine is in operation, yarn bobbins need to be placed on top of the machine for yarn feeding. The yarn wound on the bobbins is drawn into the machine through the yarn nozzle for weaving. The yarn used is usually a lightweight filament such as polyester. Filaments are not only lightweight but also elastic. Therefore, when multiple yarns are being unloaded, they are individually separated to reduce tangling. However, some flat knitting machine yarn holders only have a single slot for separating the yarns, which results in a high coefficient of friction between the yarn and the slot during unloading. This friction can lead to yarn breakage, thus reducing weaving efficiency. 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 solve the problems raised in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a yarn holder for preventing yarn breakage on a computer flat knitting machine, comprising a yarn holder plate, a limiting groove formed on the surface of the yarn holder plate, a guide rod slidably mounted on the inner side of the yarn holder plate, an auxiliary support block fixedly mounted on the surface of the guide rod, a second elastic component slidably sleeved on the surface of the guide rod, the two ends of the second elastic component being fixedly mounted on the inner side of the yarn holder plate and the surface of the auxiliary support block respectively, and a power ring rotatably mounted on the inner side of the auxiliary support block.

[0006] Preferably, the power ring is H-shaped.

[0007] Preferably, there are two sets of power rings, which are symmetrically distributed at the upper limit groove of the yarn seat plate.

[0008] Preferably, a guide ring is rotatably mounted on the inner side of the yarn seat plate, a positioning post is fixedly mounted on the surface of the guide ring, and a transparent outer cover is provided on the surface of the yarn seat plate.

[0009] Preferably, a flat knitting machine yarn holder is fixedly installed on the surface of the yarn holder plate, and a limit ring is fixedly installed on the surface of the flat knitting machine yarn holder.

[0010] Preferably, a limiting rod is slidably installed on the inner side of the transparent outer cover, and the end of the limiting rod away from the transparent outer cover is fixedly installed on the surface of the yarn seat plate.

[0011] Preferably, a first elastic component is slidably sleeved on the surface of the limiting support rod, and the two ends of the first elastic component are respectively fixedly installed on the surface of the transparent outer cover and the surface of the yarn seat plate. An auxiliary ball is fixedly installed on the surface of the transparent outer cover.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) When the yarn is unloaded through the yarn spool, the yarn will be limited at the power ring when it passes through the inner wall of the upper limit groove of the yarn holder plate. The I-shaped structure of the power ring can effectively limit the yarn, thus enabling the yarn to move stably inside the holder during unloading. The rotation adjustment between the power ring and the auxiliary support block ensures that when the yarn moves and generates high-speed friction with the power ring, the power ring can reduce the friction with the yarn through the rotation between the power ring and the auxiliary support block. This reduces the frictional resistance during the movement of the yarn, thus ensuring the smoothness of the yarn unloading. Therefore, the anti-breakage effect of the yarn is greatly improved to a certain extent, thus ensuring the reliability of the yarn holder plate.

[0014] (2) After the yarn is replaced by the yarn roll, the operator releases the auxiliary ball. The transparent outer cover is reset by the tension of the first elastic component. The transparent outer cover then covers and protects the yarn roll of the computer flat knitting machine. This method not only ensures the stable rotation effect of the yarn roll when it is placed at the guide ring, but also reduces the drawback of dust or yarn splashing caused by the rotation of the yarn roll and the resulting space pollution.

Detailed Implementation

[0021] 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.

[0022] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] In the description of this utility model, terms such as greater than, less than, and exceeding are understood to exclude the stated number, while terms such as above, below, and within are understood to include the stated number. The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0024] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0025] Please see Figure 1-4 This utility model provides a technical solution: a computer flat knitting machine anti-broken yarn holder, including a yarn holder plate 1, a flat knitting machine yarn holder body 2 fixedly installed on the surface of the yarn holder plate 1, and a limiting ring 3 fixedly installed on the surface of the flat knitting machine yarn holder body 2. The function of the limiting ring 3 is to limit the range of individual operation of the yarn body when the computer flat knitting machine uses the yarn holder plate 1, thereby reducing the disadvantage of multiple yarn bodies tilting and entangled and causing yarn breakage.

[0026] Furthermore, a guide ring 4 is rotatably installed on the inner side of the yarn holder plate 1, a positioning post 5 is fixedly installed on the surface of the guide ring 4, and a transparent outer cover 6 is provided on the surface of the yarn holder plate 1. The transparent outer cover 6 forms a shield and protection for the yarn roll of the computer flat knitting machine at the guide ring 4.

[0027] Furthermore, a limiting support rod 7 is slidably installed on the inner side of the transparent outer cover 6. The end of the limiting support rod 7 away from the transparent outer cover 6 is fixedly installed on the surface of the yarn seat plate 1. A first elastic component 8 is slidably sleeved on the surface of the limiting support rod 7. The two ends of the first elastic component 8 are respectively fixedly installed on the surface of the transparent outer cover 6 and the surface of the yarn seat plate 1. An auxiliary ball 9 is fixedly installed on the surface of the transparent outer cover 6. The operator controls the auxiliary ball 9 to drive the transparent outer cover 6 to rise on the surface of the yarn seat plate 1, so the operator can replace the yarn spool. When the yarn spool is replaced, the operator releases the auxiliary ball 9, so the transparent outer cover 6 is reset by the tension of the first elastic component 8. Thus, the transparent outer cover 6 forms a protective cover for the yarn spool of the computer flat knitting machine. This method not only ensures the stable rotation effect of the yarn spool when placed at the guide ring 4, but also reduces the drawback of dust or yarn splashing caused by the rotation and unwinding of the yarn spool, which leads to space pollution.

[0028] Furthermore, a limiting groove 10 is formed on the surface of the yarn holder plate 1. A guide rod 11 is slidably installed on the inner side of the yarn holder plate 1. An auxiliary support block 12 is fixedly installed on the surface of the guide rod 11. A second elastic component 13 is slidably sleeved on the surface of the guide rod 11. The two ends of the second elastic component 13 are respectively fixedly installed on the inner side of the yarn holder plate 1 and the surface of the auxiliary support block 12. A power ring 14 is rotatably installed on the inner side of the auxiliary support block 12. The power ring 14 is I-shaped. When the yarn is unwound by the yarn spool, when the yarn passes through the inner wall of the limiting groove 10 of the yarn holder plate 1, the yarn will be in the power ring 14. Four limiting points are formed, and the I-shaped structure of the power ring 14 can effectively limit the yarn, thus ensuring stable movement of the yarn within it during unwinding. The rotation adjustment between the power ring 14 and the auxiliary support block 12 ensures that when the yarn moves and generates high-speed friction with the power ring 14, the rotation between the power ring 14 and the auxiliary support block 12 can reduce the friction between the yarn and the power ring 14, thereby reducing the frictional resistance during the movement of the yarn and ensuring the smoothness of the yarn unwinding. This greatly improves the anti-breakage effect of the yarn to a certain extent, thus ensuring the reliability of the yarn seat plate 1.

[0029] Working principle: A computer flat knitting machine anti-broken yarn holder, controlled by the operator, uses an auxiliary ball 9 to raise a transparent outer cover 6 on the surface of the yarn holder plate 1, allowing the operator to replace the yarn spool. After the yarn spool is replaced, the operator releases the auxiliary ball 9, and the transparent outer cover 6 is reset by the tension of the first elastic component 8. The transparent outer cover 6 then covers the yarn spool of the computer flat knitting machine. When the yarn is unloaded, it is limited by the inner wall of the upper limit groove 10 of the yarn holder plate 1.

[0030] 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.
