Description

Technical Field

[0001] The utility model relates to the field of spinning frames, in particular to a yarn guiding component of a spinning frame. Background Art

[0002] With the rapid development of the textile industry, as a key device on the textile production line, the performance and efficiency of the spinning frame directly affect the quality and output of textile products.

[0003] During the yarn transmission process of traditional spinning frames, due to the lack of an effective guiding structure or an unreasonable guiding structure design, the yarn is prone to friction, extrusion or vibration, thus causing problems such as yarn skipping and yarn breaking, seriously affecting the transmission stability and continuity of the yarn.

[0004] Secondly, for the yarn guiding component of the existing spinning frame, similar to the drafting structure and working method of the flax wet spinning ring spinning frame provided by CN111172634A, its yarn guide uses a groove or channel with a fixed size to guide the yarn and cannot be flexibly adjusted according to the different diameters of the yarn. This results in the need to replace the yarn guiding component or perform cumbersome adjustment work when changing the yarn variety or specification, reducing production efficiency and flexibility. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a yarn guiding component of a spinning frame, and solve the following technical problems: how to ensure the transmission stability and continuity of the yarn, and how to flexibly adapt to yarns with different diameters and facilitate adjustment.

[0006] To solve the problems existing in the prior art, the technical solution adopted by the utility model is as follows:

[0007] A yarn guiding component of a spinning frame includes a C-shaped piece and a yarn guiding piece. The C-shaped piece is slidably connected to the outside of the yarn guiding support piece of the spinning frame. A yarn guiding piece is provided at the top of the C-shaped piece. A connecting plate horizontally extends from one side of the yarn guiding piece and is arranged on the top of the C-shaped piece for connecting with the C-shaped piece. A plurality of sheet-shaped grooves are equidistantly formed on the other side of the yarn guiding piece, and the inner side of the groove is arc-shaped. The groove is used to guide the passing yarn.

[0008] Preferably, an adjusting bolt is threadedly connected to the side of the C-shaped piece away from the yarn guiding piece. By tightening or loosening the adjusting bolt, the tightness relationship between the C-shaped piece and the yarn guiding support piece can be adjusted, so as to realize the precise adjustment and fixation of the position of the C-shaped piece.

[0009] Preferably, a waist-shaped hole is formed at the top of the connecting plate, and a screw rod is slidably connected inside the waist-shaped hole. The bottom end of the screw rod is threadedly connected to the C-shaped piece. By adjusting the position of the screw rod in the waist-shaped hole, the distance between the yarn guiding piece and the C-shaped piece can be conveniently adjusted.

[0010] Preferably, the yarn guiding member includes a main body portion and a movable portion. The main body portion is disposed on one side of the C-shaped piece, and the movable portion is slidably connected at equal intervals on the side of the main body portion away from the C-shaped piece. Grooves are formed on the yarn guiding member between adjacent movable portions.

[0011] Preferably, an adjusting piece is slidably connected to the side of the main body portion close to the C-shaped piece. Guide grooves are equidistantly formed on the surface of the adjusting piece, and the distance between the guide grooves gradually increases from bottom to top. The distance between adjacent guide grooves on the same horizontal line is equal. A slideway is formed on one side of the main body portion, and sliding rods are equidistantly slidably connected inside the slideway. One end of the sliding rod is fixedly connected to the corresponding movable portion, and the other end of the sliding rod is slidably connected inside the corresponding guide groove.

[0012] Preferably, a retaining piece is fixedly connected to the end of the sliding rod, and the retaining piece is in pressing contact with the adjusting piece. The pressing force between the retaining piece and the adjusting piece can maintain the stability of the groove width and prevent the width change caused by vibration or external interference.

[0013] Preferably, positioning pieces are symmetrically provided on one side of the main body portion, and both sides of the adjusting piece are respectively slidably connected to the corresponding positioning pieces. The positioning pieces are used to ensure that the adjusting piece remains stable during the sliding process and prevent it from deviating from the predetermined trajectory or shaking.

[0014] Preferably, pressing pieces are provided on both sides of the bottom of the adjusting piece, and the adjusting piece is dragged by pressing to adjust the groove width.

[0015] Compared with the related art, the utility model has the following beneficial effects:

[0016] 1. Through the sheet-shaped grooves equidistantly formed on the yarn guiding member, and the inner side of the grooves is designed in an arc shape, the utility model can smoothly guide the yarn to pass through, effectively reducing the friction and resistance of the yarn during the transmission process, ensuring the stability and continuity of the yarn, and reducing the occurrence of yarn skipping phenomenon.

[0017] 2. The yarn guiding member adopts a combined design of a main body portion and a movable portion, so that the width of the groove can be dynamically adjusted according to the thickness of the yarn. By pulling the adjusting piece, the sliding rod is guided to slide in the slideway, driving the movable portions to disperse or gather with each other, so as to adapt to yarns of different diameters, and improving the adaptability and flexibility of the component.

[0018] 3. The C-shaped piece is connected to the yarn guiding support member through an adjusting bolt, realizing precise adjustment and fixation of the position. Tightening the adjusting bolt can stably position the C-shaped piece, and loosening it is convenient for adjusting the position. This design not only ensures the stability of the installation but also provides the convenience of adjustment. In addition, the combination of the waist-shaped holes on the connecting plate and the screw allows adjusting the distance between the yarn guiding member and the C-shaped piece, further optimizing the yarn transmission path.

Detailed implementation manners

[0025] In order to make the purpose, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0026] The yarn guiding assembly of the spinning frame has a C-shaped piece 1 and a yarn guide member 2;

[0027] As Figures 1 to 5 shown, the C-shaped piece 1 is slidably connected to the outside of the yarn guiding support member of the spinning frame. A yarn guide member 2 is provided at the top of the C-shaped piece 1. A connecting plate 3 horizontally extends from one side of the yarn guide member 2. The connecting plate 3 is arranged at the top of the C-shaped piece 1 and is used to connect with the C-shaped piece 1. A plurality of sheet-shaped grooves 4 are equidistantly opened on the other side of the yarn guide member 2. The inner side of the groove 4 is arc-shaped. The groove 4 is used to guide the passing yarn;

[0028] As a key guiding component of the yarn, the yarn guide member 2 is installed on the yarn guiding support member of the spinning frame. According to production requirements, multiple yarn guide members 2 can be flexibly set to disperse the tension of multiple yarns and reduce the resistance of yarn jumping. The sheet-shaped groove 4 has an arc-shaped inner side, which can smoothly guide the yarn to pass through, ensuring the stability and continuity of the yarn during transmission.

[0029] As Figures 1 to 5 shown, an adjusting bolt 5 is threadedly connected to the side of the C-shaped piece 1 away from the yarn guide member 2. The C-shaped piece 1 is slidably connected to the outside of the yarn guiding support member of the spinning frame, and its position can be precisely adjusted by the tightness relationship between the adjusting bolt 5 and the yarn guiding support member. When it is necessary to fix the C-shaped piece 1, tightening the adjusting bolt 5 can achieve stable positioning; on the contrary, loosening the adjusting bolt 5 can easily adjust the position of the C-shaped piece 1.

[0030] As Figures 1 to 5 shown, a waist-shaped hole 6 is formed at the top of the connecting plate 3, and a screw rod 7 is slidably connected inside the waist-shaped hole 6. The bottom end of the screw rod 7 is threadedly connected to the C-shaped piece 1. This design allows for conveniently adjusting the distance between the yarn guiding member 2 and the C-shaped piece 1 by adjusting the position of the screw rod 7 inside the waist-shaped hole 6. This distance adjustment function helps to optimize the yarn transmission path and reduce friction and resistance.

[0031] As Figures 1 to 5 shown, the yarn guiding member 2 includes a main body portion 21 and a movable portion 22. The main body portion 21 is disposed on one side of the C-shaped piece 1, and the movable portion 22 is slidably connected to the side of the main body portion 21 away from the C-shaped piece 1 at equal intervals. Grooves 4 are formed on the yarn guiding member 2 between adjacent movable portions 22;

[0032] The movable portions 22 that can slide relative to each other enable the width of the groove 4 to be adjusted to accommodate yarns of different diameters. Adjusting the width of the groove 4 can ensure that the yarns maintain an appropriate position during transmission, reducing the risk of deviation and entanglement.

[0033] As Figures 1 to 5 shown, an adjusting piece 8 is slidably connected to the side of the main body portion 21 close to the C-shaped piece 1. Guide grooves 9 are formed on the surface of the adjusting piece 8 at equal intervals, and the distance between adjacent guide grooves 9 increases gradually from bottom to top, and the distance between adjacent guide grooves 9 on the same horizontal line is equal. A slideway 10 is formed on one side of the main body portion 21, and slide rods 11 are slidably connected inside the slideway 10 at equal intervals. One end of each slide rod 11 is fixedly connected to the corresponding movable portion 22, and the other end of each slide rod 11 is slidably connected inside the corresponding guide groove 9;

[0034] The width of the groove 4 of the yarn guiding member 2 can be dynamically adjusted by the adjusting piece 8. When the adjusting piece 8 is pulled, the guide grooves 9 on its surface will guide the slide rods 11 to slide inside the slideway 10 of the main body portion 21. Since one end of each slide rod 11 is fixedly connected to the movable portion 22 and the other end is slidably connected inside the guide groove 9, the movement of the adjusting piece 8 will drive the slide rods 11 and the movable portions 22 to disperse or gather relative to each other, thereby changing the width of the groove 4. This adjustment mechanism enables the yarn guiding member 2 to adapt to yarns of different thicknesses and ensures the smoothness of yarn transmission.

[0035] As Figures 1 to 5 shown, a stop piece 12 is fixedly connected to the end of the slide rod 11, and the stop piece 12 is in pressing contact with the adjusting piece 8;

[0036] The extrusion contact design between the retaining piece 12 and the adjusting piece 8 enables the adjusting piece 8 to maintain its current position unchanged without external force. This locking mechanism ensures the stability of the width of the groove 4 and avoids width changes caused by vibration or external interference. When the width of the groove 4 needs to be adjusted, simply apply an external force to the adjusting piece 8 to overcome the extrusion force of the retaining piece 12 and slide the adjusting piece 8 to the desired position.

[0037] As Figures 1 to 5 shown, positioning pieces 13 are symmetrically provided on one side of the main body portion 21. Both sides of the adjusting piece 8 are slidably connected to the corresponding positioning pieces 13. The cooperation between the positioning pieces 13 and the adjusting piece 8 makes the adjusting piece 8 move more smoothly when sliding.

[0038] As Figures 1 to 5 shown, pressing pieces 14 are provided on both sides of the bottom of the adjusting piece 8. By means of the pressing pieces 14, it is more labor-saving to drag the adjusting piece 8 during adjustment 3.

[0039] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
