Description

Technical Field

[0001] The utility model relates to the textile field, in particular to a yarn guiding bracket. Background Art

[0002] Generally, yarns need to be guided and supported by guide holes during long-distance transportation, which is commonly used in the transportation of multi-layer yarns. During the transportation process, the yarns are not always in a moving state. When the yarns start to be transported, the yarns will generate instantaneous tension, which will be transmitted to the yarn support structure. However, these support structures often have no buffering performance, and it is easy for the yarns to act in the opposite direction during the instantaneous start of transmission, causing the yarns to break.

[0003] In response to the above phenomenon, patent CN218809607U mentions a yarn buffering guide bracket, including a mounting plate, an adjusting arm, a limiting pull rod, a yarn guide arm and a buffer module; a flippable adjusting arm is provided to adjust the height of the overall yarn guide arm, and the limiting pull rod is used to limit the adjusted adjusting arm. In addition, a buffer module is provided between the yarn guide arm and the oblique arm of the adjusting arm. The point contact between the yarn guide arm and the oblique arm is utilized. When the yarn guide arm is subjected to instantaneous pressure of the yarn, the pressure is transmitted to the connecting screw and then to the spring. The elastic potential energy of the spring is used to buffer the yarn, thereby reducing the reaction force when the yarn is instantly started and transported, and reducing the possibility of yarn breakage.

[0004] The guide bracket in the above patent uses connecting bolts, springs and other components to connect the yarn guide arm and the oblique arm. In this connection method, when the yarn guide arm is damaged, bent or needs to be replaced due to length problems, it is necessary to loosen the connecting bolts first and then replace the new yarn guide arm. When fixing, the position, angle and spring tension of the yarn guide arm need to be adjusted multiple times before the replacement can be completed. The whole process is very troublesome.

[0016] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0017] like Figure 1 , Figure 2 A yarn guide bracket shown includes a mounting plate 1, an adjusting arm, a limiting pull rod 3, a yarn guide arm and a buffer module.

[0018] The mounting plate 1 is vertically arranged, and the adjusting arm includes an oblique arm 21 and a driving arm 22 respectively arranged on both sides of the mounting plate 1, and the oblique arm 21 is connected to the driving arm 22 at an obtuse angle. There are several yarn guide arms, which are installed in parallel on the oblique arm 21, and the yarn guide arm and the oblique arm 21 are fixed by the cooperation of the buffer module. A guide groove wheel 411 for supporting the yarn is also installed on the side of the yarn guide arm away from the oblique arm 21.

[0019] The yarn guide arm includes a support arm 41 and a connecting arm 42. The guide groove wheel 411 is installed on the support arm 41. The connecting arm 42 is bent on one side away from the support arm to form a bending edge. An arc-shaped protrusion 421 is provided on the bending edge. The arc-shaped protrusion 421 is fixed on the inclined arm 21 through the cooperation of the buffer module.

[0020] In the present application, the specific structure and working principle of the mounting plate 1, the adjusting arm, the limiting pull rod 3, the yarn guide arm and the buffer module are the same as the structure and working principle of a yarn buffer guide bracket mentioned in CN218809607U, and will not be described in detail in this embodiment.

[0021] The connecting arm 42 includes a connecting arm body 422 and a fixing ring 423. A notch for accommodating the fixing ring 423 is opened on the outer wall of one side of the connecting arm body 422. The connecting arm body 422 and the fixing ring 423 are connected and fixed by a detachable component. One side of the connecting arm body 422 is fixed to the support arm 41, and the fixing ring 423 is fixed to the bent edge.

[0022] like Figure 2 As can be seen from the schematic diagram shown, the detachable component is: a fixing hole 424 extending toward the center of the connecting arm body 422 is opened in the middle position of the connecting arm body 422 close to the fixing ring 423, and the fixing hole 424 is in the shape of a regular quadrangular pyramid. A fixing piece 425 that fits the shape thereof is inserted into the fixing hole 424, and the fixing piece 425 is also in the shape of a regular quadrangular pyramid.

[0023] Several locking holes connected with the fixing hole 424 are also provided at the notch of the connecting arm body 422, and a locking piece 426 is installed in the locking hole. The locking piece 426 is cylindrical, and a reset spring 427 is also provided between the locking piece 426 and the locking hole. The connection is specifically as follows: a mounting cavity 428 for mounting and moving the reset spring 427 is also provided on the connecting arm body 422 at the reset spring 427, and the mounting cavity 428 is annular and connected with the locking hole, the reset spring 427 is sleeved on the outer wall of the locking piece 426 and is located in the mounting cavity 428, and a ring-shaped limiting ring 429 is also connected to the circumferential outer wall of the locking piece 426, one side of the reset spring 427 abuts against the inner wall of the mounting cavity 428, and the other side of the reset spring 427 abuts against the side wall of the limiting ring 429.

[0024] One side of the locking piece 426 extends into the fixing hole 424, and the other side of the locking piece 426 is flush with the circumferential outer wall of the notch of the connecting arm body 422, and the locking piece 426 extends out of the connecting arm body 422 under the push of the fixing piece 425. The cooperation between the fixing piece 425 and the locking piece 426 is as follows: the four side surfaces of the fixing piece 425 are all inclined surfaces, and the inclination direction of the inclined surface is from the end of the connecting arm body 422 to the center direction of the connecting arm body 422 and gradually inclines toward the direction approaching the locking piece 426. There are four locking pieces 426 in total, which correspond to the four inclined surfaces of the fixing piece 425 one by one, and the side wall of the locking piece 426 close to the fixing piece is an inclined surface that fits the side surface of the fixing piece 425. The fixing member 425 is designed in the shape of a regular quadrangular pyramid, and is combined with the inclined surface of the side wall of the locking member 426, and is combined with the return spring 427, so that the locking member 426 can be retracted into the connecting arm body 422 when the connecting arm body 422 is installed or disassembled, thereby preventing the locking member 426 from extending out of the connecting arm body 422 and affecting the installation or disassembly of the connecting arm body 422.

[0025] A blind hole is provided on the inner wall of the fixing ring 423 for inserting a section of the locking piece 426 extending out of the locking hole. Two fixing bolts pass through the fixing ring 423 and the connecting arm body 422 in turn and are threadedly fixed to the fixing piece 425, thereby achieving fixation between the fixing ring 423 and the connecting arm body 422. Through holes for the fixing bolts to pass through are provided on the fixing ring 423 and the connecting arm body 422 respectively, and a threaded blind hole threadedly matched with the fixing bolt is provided on the fixing piece 425. The design of the detachable component adopts the cooperation of the fixing member 425, the locking member 426, the fixing hole 424, the locking hole and the fixing bolt to realize the fixation between the fixing ring 423 and the connecting arm body 422. All accessories have no direct fixing relationship with the connecting arm body 422 and the fixing ring 423, which provides a basis for the convenience of subsequent replacement of the fixing ring 423; when in use, the relative fixation between the fixing ring 423 and the connecting arm body 422 is realized by extending the locking member 426 into the blind hole, so that most of the relative rotation force between the fixing ring 423 and the connecting arm body 422 is borne by the locking member 426, which greatly reduces the force borne by the fixing bolt, avoids the fixing bolt from bending, breaking and other undesirable phenomena due to excessive force, and affects the subsequent disassembly and replacement of the connecting arm body 422.

[0026] With the above structure, when the yarn guide arm needs to be replaced, the two fixing bolts are directly loosened, and the fixing member 425 is then pulled out. As the fixing member 425 is pulled out, one side of the locking member 426 moves into the fixing hole 424 driven by the return spring 427, and the other side of the locking member 426 is disengaged from the blind hole, thereby ending the locking between the fixing ring 423 and the connecting arm body 422. At this time, the old connecting arm body 422 is directly removed and replaced with a new connecting arm body 422.

[0027] When installing a new connecting arm body 422, the side end of the connecting arm body 422 is extended into the fixing ring 423. At this time, the locking piece 426 will not extend out of the connecting arm body 422 under the influence of the return spring 427, and the other side of the corresponding locking piece 426 will extend into the fixing hole 424. After the fixing ring 423 is installed, the fixing piece 425 is inserted into the fixing hole 424 from the side end of the connecting arm body 422. During the insertion process, as the fixing piece 425 moves, the fixing piece 425 will touch the side of the locking piece 426 extending into the fixing hole 424, and as the fixing piece 425 continues to move, the fixing piece 425 will gradually push the locking piece 426 up The fixing member 425 is completely embedded in the fixing hole 424, and one side of the locking member 426 is completely withdrawn from the fixing hole 424, while the other side of the locking member 426 is extended into the blind hole, thereby realizing relative limit locking between the fixing ring 423 and the connecting arm body 422. Finally, two fixing bolts are passed through the fixing ring 423 and the connecting arm body 422 in turn and are threadedly locked with the fixing member 425 to complete the fixation between the fixing ring 423 and the connecting arm body 422, thereby forming a complete connecting arm.

[0028] The yarn guide bracket in the utility model retains the fixing ring 423 to ensure the position and angle of the replaced yarn guide arm, thereby ensuring the position, tilt angle and other factors of the replaced yarn guide arm. Moreover, there is no need to operate the buffer module, and there is no need to adjust the tension of the spring in the buffer module, so replacement is very convenient.

[0029] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
