TECHNICAL FIELD
[0001] The present application relates to the field of yarn bobbins, in particular to a yarn bobbin capable of preventing yarn from loosening. BACKGROUND
[0002] In the textile industry and related yarn use scenarios, yarn bobbins are important tools for storing and winding yarn. Traditional yarn bobbins have a relatively simple structure and usually only have a simple winding function, lacking effective yarn anti-loosening and positioning design.
[0003] Many traditional yarn bobbins have a bobbin structure with fixed side plates at both ends. Although this design can block the yarn to some extent, it has obvious defects. On the one hand, the fixed side plates make the overall volume of the bobbin larger, occupying more space when stored, which is not conducive to storage and transportation, increasing the cost of warehousing and logistics. On the other hand, when it is necessary to adjust the positioning range of the yarn to adapt to the winding needs of yarns of different specifications, the traditional bobbin cannot be flexibly adjusted, making it difficult to meet the diverse use scenarios.
[0004] In addition, some yarn bobbins without side plates or with unreasonable side plate design are prone to yarn loosening during use, resulting in disordered winding of the yarn, affecting production efficiency, and even causing damage to the yarn, increasing production costs. Therefore, it is of great practical significance to develop a yarn bobbin that can effectively prevent yarn loosening, is easy to store, and can flexibly adjust the positioning range. SUMMARY
[0005] The present application aims to provide a yarn bobbin capable of preventing yarn from loosening to solve the problems raised in the background.
[0006] To achieve the above-mentioned purpose, the present application provides the following technical solution: a yarn bobbin capable of preventing yarn from loosening, comprising a yarn bobbin body, a receiving groove is formed at both ends of the yarn bobbin body, a limiting plate is rotatably connected inside the receiving groove, a push tube is inserted and screwed into the end of the yarn bobbin body, and a handle is inserted into the inner wall of the yarn bobbin body. The surface of the push tube is integrally formed with a clamping strip, the surface of the limiting plate is provided with a positioning groove, after the limiting plate is received in the receiving groove, the push tube is screwed into the yarn bobbin body, the clamping strip is inserted into the end of the yarn bobbin body and the limiting plate, and the push tube pushes the handle inserted into the positioning groove. When the limiting plate extends from the receiving groove and is perpendicular to the yarn bobbin body, after the push tube is screwed into the yarn bobbin body, the push tube pushes the handle to block one side of the limiting plate, and the limiting plate is clamped between the limiting plate and the side wall of the receiving groove.
[0007] Preferably, the receiving grooves are provided in plurality, and the plurality of receiving grooves are circumferentially distributed with the yarn bobbin body as the central axis, and a limiting shaft is fixed between the two parallelly distributed side walls of the receiving groove, and the limiting shaft penetrates the through hole formed on the surface of the limiting plate.
[0008] Preferably, the length of the limiting plate is equal to the length of the long side of the receiving groove, and a clamping groove two is formed at one end of the limiting plate, and a clamping groove one is formed at one end of the yarn bobbin body, and the clamping groove two and the clamping groove one are both circular arc grooves, and the clamping groove one is connected with the plurality of receiving grooves, and the clamping strip is in the form of a ring-shaped plate structure, and the clamping strip is inserted into the clamping groove one and the clamping groove two.
[0009] Preferably, the pushing cylinder is in the form of a "T" shaped cylinder, and the outer ring diameter of one end of the pushing cylinder is equal to the outer ring diameter of the yarn bobbin body, and an external thread is formed on the outer wall of the pushing cylinder, and an internal thread is formed on the inner ring opening of the yarn bobbin body, and the internal thread and the external thread are connected in cooperation.
[0010] Preferably, the inner ring surface of the pushing cylinder is fixed with a rotating handle, and the rotating handle is in the form of a "cross" shaped strip.
[0011] Preferably, a plurality of sockets are formed on the inner wall of the yarn bobbin body, and the sockets are in one-to-one correspondence with the receiving grooves, and the sockets are connected with the receiving grooves, and the insertion handle is inserted into the socket, and the height of the insertion handle is greater than the depth of the socket.
[0012] Preferably, the end of the insertion handle extending to the inner side of the yarn bobbin body is provided with an inclined surface, and when the pushing cylinder is pushed into the yarn bobbin body, the pushing cylinder pushes the insertion handle to retract into the socket along the inclined surface.
[0013] Preferably, a notch is formed at the other end of the insertion handle, and a blocking strip is inserted into the notch, and the blocking strip is fixed between the two parallelly distributed side walls of the socket, and a rubber supporting block is fixed on the surface of the blocking strip, and the other end of the rubber supporting block is fixed on the surface of the notch, and when the pushing cylinder does not press the insertion handle, the rubber supporting block is in the initial state, and at this time, the rubber supporting block pulls the other end of the insertion handle to retract into the socket, and when the pushing cylinder pushes the insertion handle, the insertion handle presses the rubber supporting block to produce elastic deformation.
[0014] Compared with the prior art, the yarn bobbin provided by the present application has the following advantages: The yarn bobbin provided by the present application can prevent the yarn from loosening, and when the limiting plate is extended from the receiving groove and is perpendicular to the yarn bobbin body, the pushing cylinder pushes the insertion handle to block on one side of the limiting plate, and the limiting plate is limited between the insertion handle and the receiving groove, so that the two groups of limiting plates form effective blocking to the yarn. In this way, the yarn wound on the surface of the yarn bobbin body is limited between the two groups of limiting plates, greatly reducing the possibility of yarn loosening, ensuring the neatness and stability of the yarn winding, and improving the production efficiency and the quality of the yarn.
[0015] When the yarn bobbin needs to be stored, the limiting plate can be pushed into the corresponding storage slot, and then the pusher can be turned to push it into the yarn bobbin, so that the locking strip is inserted into the locking slot one and the locking slot two, fixing the limiting plate in the storage slot. At this time, the yarn bobbin presents a single tube body. Compared with the traditional bobbin with two fixed side plates, its storage space is greatly reduced, which facilitates the storage and transportation of yarn bobbins and reduces warehousing and logistics costs.
[0016] The yarn bobbin of this invention allows for flexible adjustment of the limiting plate's state according to actual needs. When the limiting plate is required to prevent yarn slippage, the insertion state of the locking strip and the locking slot is controlled by rewinding and rotating the push cylinder, enabling the limiting plate to switch between a stored state and a working state. This flexible adjustment method allows the yarn bobbin to adapt to the winding requirements of different yarn specifications and different usage scenarios, improving the versatility and practicality of the yarn bobbin.

[0022] When the yarn bobbin body 1 needs to be accommodated, the limiting plate 2 is pushed into the corresponding accommodating groove 101, then the handle 302 is pinched and rotated to push the pushing barrel 3 to advance into the inside of the yarn bobbin body 1, the pushing barrel 3 extrudes the insertion handle 4 to insert into the positioning groove 203 along the inclined surface, until the clamping strip 301 is inserted into the clamping groove one 102 and the clamping groove two 201, the limiting plate 2 will not swing in the accommodating groove 101, achieving the limiting of the limiting plate 2 in the accommodating groove 101, at this time, the yarn bobbin body 1 is a single tube, compared with the traditional bobbin with two side plates, the yarn bobbin body 1 occupies a smaller accommodation space.
[0023] When the limiting plate 2 extends from the storage groove 101 and is perpendicular to the yarn bobbin body 1, and the push cylinder 3 is inserted into the yarn bobbin body 1, the push cylinder 3 pushes the insertion handle 4 to block one side of the limiting plate 2, and the limiting plate 2 is clamped between the limiting plate 2 and the side wall of the storage groove 101. When it is necessary to use the limiting plate 2 to prevent the yarn wound on the yarn bobbin body 1 from falling off, the push cylinder 3 is unscrewed and moved away from the yarn bobbin body 1 until the clamping strip 301 is separated from the clamping groove one 102 and the clamping groove two 201, and then the limiting plate 2 is rotated by ninety degrees to the outside of the storage groove 101 around the corresponding limiting shaft 204. When the limiting plate 2 is perpendicular to the yarn bobbin body 1, the push cylinder 3 is screwed towards the inside of the yarn bobbin body 1 until the push cylinder 3 pushes the insertion handle 4 to block one side of the limiting plate 2. At this time, the limiting plate 2 is limited between the insertion handle 4 and the storage groove 101 and cannot swing. After the two sets of limiting plates 2 are adjusted, the yarn wound on the surface of the yarn bobbin body 1 is limited between the two sets of limiting plates 2.
[0024] Method for preventing yarn from falling off using yarn bobbin: I. Storage state setting (storing the limiting plate 2 in the storage groove 101) The limiting plate 2 is pushed into the corresponding storage groove 101 so that the surface of the limiting plate 2 is flush with the opening of the storage groove 101, ensuring that the limiting plate 2 is completely stored. The "cross" shaped rotating handle 302 at the end of the push cylinder 3 is pinched by hand, and the end of the push cylinder 3 with external threads is screwed into the internal threaded ring opening of the yarn bobbin body 1. Continue to screw the push cylinder 3 so that it advances towards the inside of the yarn bobbin body 1 until the outer ring diameter of the end of the push cylinder 3 is aligned with the outer ring diameter of the yarn bobbin body 1. During the advancement of the push cylinder 3, the annular plate-shaped clamping strip 301 integrally formed on the surface of the push cylinder 3 is inserted into the clamping groove one 102 at the end of the yarn bobbin body 1 and the clamping groove two 201 at the end of the limiting plate 2. At the same time, the inner ring surface of the push cylinder 3 extrudes the insertion handle 4 (the insertion handle 4 is initially pulled and shrunk into the insertion opening 103 by the rubber supporting block 403), and the insertion handle 4 is extruded out of the insertion opening 103 along the inclined surface and inserted into the positioning groove 203 on the surface of the limiting plate 2. After confirming that the clamping strip 301 is completely inserted into the clamping groove one 102 and the clamping groove two 201, and the end of the insertion handle 4 is embedded in the positioning groove 203, the limiting plate 2 is fixed in the storage groove 101 and cannot swing. The yarn bobbin body 1 presents a single tubular shape without any external extending parts, which can minimize the occupation of storage space.
[0025] II. Yarn anti-falling limiting state setting (the limiting plate 2 is perpendicular to the yarn bobbin body 1) Reverse screwing the handle 302, the push cylinder 3 moves away from the yarn bobbin body 1, until the card strip 301 is completely separated from the card slot one 102 and the card slot two 201. Turn the limiting plate 2 around the limiting shaft 204 (fixed on the two side walls of the storage groove 101) to the outside of the storage groove 101 by 90°, until the limiting plate 2 is perpendicular to the axis of the yarn bobbin body 1. Screw the push cylinder 3 again, so that it advances to the inside of the yarn bobbin body 1. The inner ring surface of the push cylinder 3 extrudes the insertion handle 4, and the insertion handle 4 overcomes the elastic force of the rubber prop 403 and moves along the inclined surface, and finally the end of the insertion handle 4 is blocked on one side of the limiting plate 2, and the limiting plate 2 is clamped between the insertion handle 4 and the side wall of the storage groove 101, and cannot swing. Repeat the above steps to adjust the limiting plate 2 at the other end of the yarn bobbin body 1 to the vertical state and fix it. After adjusting the two sets of limiting plates 2, the yarn wound on the surface of the yarn bobbin body 1 is limited between the two sets of limiting plates 2, preventing loosening.
[0026] III. Key component cooperation logic The push cylinder 3 is screwed in / out to control the insertion state of the card strip 301 and the card slot one 102 and the card slot two 201, realizing the switching of the storage and fixation or working fixation of the limiting plate 2. The rubber prop 403 initially pulls the insertion handle 4 to shrink in the insertion port 103, and when the push cylinder 3 is extruded, the insertion handle 4 extends and inserts into the positioning groove 203 or blocks the side edge of the limiting plate 2, forming secondary limiting. The limiting shaft 204 penetrates the through hole 202 of the limiting plate 2, allowing the limiting plate 2 to rotate in the storage groove 101, while limiting it from leaving the storage groove 101.
