Description

Technical Field

[0001] This utility model specifically relates to the field of yarn guide technology, and more specifically to a compact spinning yarn guide. Background Technology

[0002] Rubber rollers are mainly used in compact spinning machines to hold and draft fiber slivers. They work in conjunction with rollers to apply appropriate pressure to keep the fiber slivers in a stable holding state during the drafting process, ensuring that the fibers can be stretched and refined evenly, thereby improving the quality and uniformity of the yarn.

[0003] During the spinning process, the front roller, middle roller, and rear roller operate at different linear speeds. The rubber roller rotates along with the rollers, stretching the fiber sliver held between the rubber roller and the rollers. The elasticity of the rubber roller not only helps to maintain a stable grip on the fiber but also ensures a more uniform tension on the fiber sliver during drafting, preventing fiber breakage or uneven drafting due to excessive local tension.

[0004] However, in practice, it has been noted that the shaft of the yarn guide is generally engaged with the end of the leaf spring. The downward pressure of the leaf spring causes the guide wheel to adhere to the top of the yarn. When the yarn moves quickly, the shaft of the yarn guide may collide with the connection point of the leaf spring, which will aggravate the wear at the connection point and affect the service life. Furthermore, when the yarn moves quickly, it is also easy for it to slip under the guide wheel, causing the yarn to move out from under the guide wheel, which will lead to yarn tangling and affect normal use. Utility Model Content

[0005] The purpose of this invention is to provide a compact yarn guide that utilizes a spring plate and a snap-fit ​​mechanism to precisely position the shaft, reducing wear at the connection points and extending service life. Furthermore, the guide wheel is equipped with a positioning groove to prevent lateral yarn movement. This addresses the technical problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A compact spinning guide includes a hollow shell, one end of which is fixedly connected to pressure regulating components in a rectangular array, and each pressure regulating component is equipped with an end holder, and a detachable yarn guide is engaged in the end holder.

[0008] The detachable yarn guide includes a fixed shaft installed in the end bracket, with rubber guide wheels movably connected to both ends of the fixed shaft, and each of the rubber guide wheels has a limiting groove.

[0009] As a further technical solution of this utility model, the end bracket includes a U-shaped groove, and the fixed shaft is placed inside the U-shaped groove. A C-shaped spring sheet is fixedly connected inside the U-shaped groove, and the C-shaped spring sheet is engaged with the side of the fixed shaft.

[0010] As a further technical solution of this utility model, the end of the U-shaped groove seat away from the C-shaped spring sheet is provided with an anti-sway positioning seat, wherein the anti-sway positioning seat includes a movable insert plate movably connected to the end of the U-shaped groove seat, and a pull-out groove is provided at the end of the movable insert plate away from the C-shaped spring sheet.

[0011] As a further technical solution of this utility model, both ends of the movable insert are fixedly connected with end baffles and limiting baffles, wherein the end baffles are located inside the U-shaped groove seat, and the limiting baffles are located outside the U-shaped groove seat.

[0012] As a further technical solution of this utility model, compression springs are arranged in a rectangular array below the movable insert plate, and one end of the compression spring is fixedly connected to the end baffle, and the other end is fixedly connected to the U-shaped groove seat.

[0013] The end of the movable insert plate is engaged with the side of the fixed shaft away from the C-shaped spring plate.

[0014] As a further technical solution of this utility model, the hollow shell is provided with symmetrical mounting grooves corresponding to the pressure regulating component, and a locking bolt is inserted into the mounting groove, and the locking bolt passes through the mounting groove and is threadedly engaged with the pressure regulating component.

[0015] As a further technical solution of this utility model, a locking bushing is installed at the end of the hollow shell away from the pressure regulating component, and an L-shaped locking handle is movably connected above the pressure regulating component.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] In this invention, when the detachable yarn guide is inserted into the inner side of the end seat, the compression spring will push the moving insert plate to move below the detachable yarn guide through the end baffle, thereby fixing the position of the detachable yarn guide inside the end seat, preventing the detachable yarn guide from moving up and down significantly during use, and without affecting the quick disassembly of the detachable yarn guide, thus reducing wear at the connection and extending its service life.

[0018] In this utility model, the fixed shaft is placed inside the U-shaped groove seat. At this time, the C-shaped spring sheet on the side of the U-shaped groove seat can engage with the bottom of the fixed shaft, so that the pressure adjustment component applies downward pressure to the detachable yarn guide. In addition, each rubber guide wheel has a limiting groove on its outer side to position the yarn and prevent it from wobbling back and forth when the limiting groove moves.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-6The present invention provides a compact spinning yarn guide, including a hollow shell 1. One end of the hollow shell 1 is fixedly connected to a pressure regulating component 4 in a rectangular array, and each pressure regulating component 4 is equipped with an end seat 6, and a detachable yarn guide 7 is engaged in the end seat 6.

[0029] The detachable yarn guide 7 includes a fixed shaft 71 installed in the end bracket 6. Both ends of the fixed shaft 71 are movably connected to rubber guide wheels 72, and each of the rubber guide wheels 72 has a limiting groove 73.

[0030] Furthermore, the end bracket 6 includes a U-shaped groove 61, and a fixed shaft 71 is placed inside the U-shaped groove 61. A C-shaped spring sheet 62 is fixedly connected inside the U-shaped groove 61, and the C-shaped spring sheet 62 is engaged with the side of the fixed shaft 71.

[0031] By adopting the above technical solution, the fixed shaft 71 is placed inside the U-shaped groove seat 61. At this time, the C-shaped spring sheet 62 on the side of the U-shaped groove seat 61 can engage with the bottom of the fixed shaft 71, thereby allowing the pressure adjustment component 4 to apply downward pressure to the detachable yarn guide 7. In addition, each rubber guide wheel 72 is provided with a limiting groove 73 on its outer side, thereby positioning the yarn and preventing it from wobbling back and forth when the limiting groove moves.

[0032] More specifically, the end of the U-shaped groove seat 61 away from the C-shaped spring sheet 62 is provided with an anti-sway positioning seat 8, wherein the anti-sway positioning seat 8 includes a movable insert plate 81 movably connected to the end of the U-shaped groove seat 61, and a pull-out groove 85 is provided at the end of the movable insert plate 81 away from the C-shaped spring sheet 62.

[0033] Furthermore, both ends of the movable insert plate 81 are fixedly connected with end baffles 82 and limiting baffles 84, wherein the end baffles 82 are located inside the U-shaped groove seat 61, and the limiting baffles 84 are located outside the U-shaped groove seat 61.

[0034] Furthermore, compression springs 83 are arranged in a rectangular array below the movable insert plate 81, and one end of the compression springs 83 is fixedly connected to the end baffle 82, and the other end is fixedly connected to the U-shaped groove seat 61.

[0035] The end of the movable insert plate 81 is engaged with the side of the fixed shaft 71 away from the C-shaped spring plate 62.

[0036] By adopting the above technical solution, when the detachable yarn guide 7 is inserted into the inner side of the end seat 6, the compression spring 83 will push the moving insert plate 81 to move below the detachable yarn guide 7 through the end baffle 82, thereby fixing the position of the detachable yarn guide 7 inside the end seat 6, preventing the detachable yarn guide 7 from moving up and down significantly during use, and not affecting the quick disassembly of the detachable yarn guide 7, thereby reducing wear at the connection and extending its service life.

[0037] Furthermore, the hollow outer shell 1 is symmetrically provided with mounting grooves 5 corresponding to the pressure regulating component 4, and a locking bolt is inserted into the mounting groove 5, and the locking bolt passes through the mounting groove 5 and is threadedly engaged with the pressure regulating component 4.

[0038] Furthermore, a locking bushing 2 is installed at the end of the hollow outer shell 1 away from the pressure regulating component 4, and an L-shaped locking handle 3 is movably connected above the pressure regulating component 4.

[0039] Furthermore, one end of the L-shaped locking handle 3 is positioned parallel to the top of the hollow outer shell 1, while the other end of the L-shaped locking handle 3 extends to the inner end of the L-shaped locking handle 3.

[0040] Furthermore, the rubber guide wheel 72 is composed of three rubber wheels of different hardness in one piece, with the harder rubber wheel in the middle and the softer rubber wheels on both sides. When the pressure regulating component 4 applies downward pressure to the rubber guide wheel 72, the two sides of the rubber guide wheel 72 will deform until the middle position of the rubber guide wheel 72 contacts the spinning machine; while applying pressure to the yarn, it also plays a limiting role.

[0041] The working principle of this utility model is as follows: First, the fixed shaft 71 is inserted into the inner side of the U-shaped groove 61, and cooperates with the C-shaped spring plate 62 inside the U-shaped groove 61 to secure the fixed shaft 71 within the U-shaped groove 61. Simultaneously, the compression spring 83 applies pressure to the movable insert plate 81 via the end baffle 82, causing the end of the movable insert plate 81 to engage below the fixed shaft 71. Then, the pressure adjusting component 4 applies downward pressure to the detachable yarn guide 7, allowing the yarn to pass under the rubber guide wheel 72. After the rubber guide wheel 72 is released from the bottom spinning machine, its sides are compressed and deformed, cooperating with the limiting groove 73 in the middle of the rubber guide wheel 72 to position the yarn and prevent it from wobbling. The structure is simple, the operation is very convenient, and it effectively reduces manual labor intensity.
