Description

Technical Field

[0001] This utility model relates to the textile field, specifically to a textile yarn guide seat. Background Technology

[0002] The yarn guide is an important component of textile machinery. It works in conjunction with the yarn guide needle to guide the movement of the yarn, ensuring its correct path during the textile process, preventing yarn misalignment, and improving textile quality and efficiency.

[0003] A Chinese patent (CN105523436A) discloses a novel textile yarn guide seat, comprising a positioning plate 1, yarn guide needles 2, a positioning seat 3, a mounting cavity 4, a pressure block 5, a screw 6, and an elastic component 7. The positioning plate 1 is disposed within the positioning seat 3, and a plurality of yarn guide needles 2 are fixedly disposed on the upper end face of the positioning plate 1, arranged in an orderly manner. The yarn guide needles on the positioning plate 1 pass through the positioning seat 3 and protrude from the outside of the positioning seat 3. The positioning seat 3 has a mounting cavity 4 for accommodating the positioning plate 1, and a locking structure for tightly locking the positioning plate 1 within the positioning seat 3, including a pressure block 5 for pressing the positioning plate 1 into the positioning seat, and a screw 6 for locking the pressure block 5 onto the positioning seat 3. An elastic component 7 is disposed between the pressure block and the positioning seat. The elastic component 7 can be a spring, a sheet, or a rubber pad. The invention uses a locking structure to lock the positioning plate 1 inside the positioning seat 3, and the yarn guide needle 2 extends out of the positioning seat 3 to guide the yarn. The positioning plate is firmly confined in the positioning seat and will not loosen, thus ensuring that the yarn guide needle 2 guides the yarn smoothly.

[0004] The above-mentioned yarn guide seat also has the following problems when in use: the elastic potential energy of the elastic component in the yarn guide seat weakens after a long period of use, and it is inconvenient to disassemble and replace the elastic component, resulting in poor performance of the yarn guide seat and thus affecting subsequent textile operations.

[0005] Therefore, it is necessary to invent a textile yarn guide to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a textile yarn guide seat to solve the problems mentioned in the background art, such as the weakening of elastic potential energy of the elastic component in the yarn guide seat after a long period of use, and the inconvenience of disassembling and replacing the elastic component, resulting in poor performance of the yarn guide seat and affecting subsequent textile operations.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a textile yarn guide seat, including a positioning seat, a base plate is movably mounted on the bottom of the positioning seat by screws, and a pressure block is fixedly mounted on the top of the base plate. An upper end plate is elastically mounted on the top of the pressure block by an elastic element. A yarn guide needle is fixedly mounted on the top of the upper end plate, wherein the yarn guide needle passes through the top of the positioning seat. An upper threaded block and a lower threaded block are respectively fixedly mounted on the upper and lower ends of the elastic element, and the upper threaded block and the lower threaded block are threadedly connected to the upper end plate and the pressure block, respectively. The upper threaded block and the lower threaded block are rotated together by a linkage component.

[0008] Preferably, the elastic element consists of a spring and a damping rod, with the spring movably fitted onto the outer ring of the damping rod. The two ends of the spring and the damping rod are respectively fixedly connected to the ends of the upper threaded block and the lower threaded block, wherein the outer ring threads of the upper threaded block and the lower threaded block have opposite directions to ensure the smooth replacement and installation of the elastic element in the future.

[0009] Preferably, the linkage components are provided in two sets, and the two sets of linkage components are symmetrically arranged with reference to the central axis of the upper threaded block as the axis of symmetry. The upper threaded block and the lower threaded block can be rotated synchronously through the two sets of linkage components.

[0010] Preferably, the linkage assembly includes a threaded rod 2 and a threaded rod 1 that are threadedly connected to the upper threaded block and the lower threaded block respectively. The threaded rod 2 is slidably installed inside a pre-set vertical groove inside the threaded rod 1. The outer ring of the threaded rod 2 and the threaded rod 1 is threaded, while the outer ring of the remaining rod is smooth. The linkage assembly can be disassembled and assembled by twisting the threaded rod 1 and the threaded rod 2.

[0011] Preferably, the linkage component further includes an annular groove preset inside the threaded rod one, and an annular block is rotatably installed inside the annular groove, and a crossbar is fixedly connected to the inner wall of the annular block. The crossbar slides into a limiting groove preset inside the threaded rod two, ensuring the anti-disengagement connection of the threaded rod one and the threaded rod two without affecting the rotation of the threaded rod one and the threaded rod two.

[0012] Preferably, both the upper and lower ends of the limiting groove are closed, and the inner wall of the limiting groove is attached to the outer wall of the crossbar to achieve a sliding connection between the upper and lower parts.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] This invention allows the pressure block, upper end plate, and bottom plate to be removed by unscrewing the screws. Then, a set of two symmetrically arranged linkage components is pinched to cause the upper and lower threaded blocks to rotate synchronously. The outer threads of the upper and lower threaded blocks have different directions, so when the upper and lower threaded blocks rotate in the same direction, they achieve similar movements. When the upper and lower threaded blocks rotate and separate from the internal thread grooves of the pressure block and the upper end plate, the entire elastic element can be easily removed and replaced.

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] This utility model provides, for example Figure 1-5The textile yarn guide seat shown includes a positioning seat 1. A base plate 2 is movably mounted on the bottom of the positioning seat 1 by screws 3, and a pressure block 4 is fixedly mounted on the top of the base plate 2. An upper end plate 5 is elastically mounted on the top of the pressure block 4 by an elastic element 7. A yarn guide needle 6 is fixedly mounted on the top of the upper end plate 5, wherein the yarn guide needle 6 passes through the top of the positioning seat 1. An upper threaded block 8 and a lower threaded block 9 are fixedly mounted on the upper and lower ends of the elastic element 7, respectively. The upper threaded block 8 and the lower threaded block 9 are threadedly connected to the upper end plate 5 and the pressure block 4, respectively. The upper threaded block 8 and the lower threaded block 9 are rotated together by a linkage component 10.

[0025] By removing screw 3, the pressure block 4, upper end plate 5, and bottom plate 2 can be taken out. Then, a set of two symmetrically arranged linkage components 10 is pinched, causing the upper threaded block 8 and lower threaded block 9 to rotate synchronously. The outer threads of the upper threaded block 8 and lower threaded block 9 have different directions. When the upper threaded block 8 and lower threaded block 9 rotate in the same direction, they achieve similar movements. When the upper threaded block 8 and lower threaded block 9 rotate and separate from the internal thread grooves of the pressure block 4 and upper end plate 5, it is convenient to remove and replace the entire elastic element 7.

[0026] To ensure the smooth and stable elastic movement of the elastic element 7, the elastic element 7 is composed of a spring and a damping rod. The spring is movably fitted on the outer ring of the damping rod, and the two ends of the spring and the damping rod are fixedly connected to the ends of the upper threaded block 8 and the lower threaded block 9, respectively. The outer ring threads of the upper threaded block 8 and the lower threaded block 9 have opposite directions to ensure the smooth replacement and installation of the elastic element 7 in the future.

[0027] There are two sets of linkage components 10, and the two sets of linkage components 10 are symmetrically arranged with reference to the central axis of the upper threaded block 8. The upper threaded block 8 and the lower threaded block 9 can be rotated synchronously through the two sets of linkage components 10 (at this time, the two sets of linkage components 10 are revolving around each other, which is different from the rotation of the subsequent thread rod 101 and thread rod 202).

[0028] The linkage assembly 10 includes a second threaded rod 102 and a first threaded rod 101 that are threadedly connected to the upper threaded block 8 and the lower threaded block 9, respectively. The second threaded rod 102 is slidably installed inside the pre-set vertical groove 103 inside the first threaded rod 101. The outer ring of the second threaded rod 102 and the first threaded rod 101 is threaded, while the outer ring of the remaining rod is smooth. The linkage assembly 10 can be disassembled and assembled by twisting the first threaded rod 101 and the second threaded rod 102.

[0029] The linkage component 10 also includes an annular groove 104 pre-set inside the threaded rod 101, and an annular block 105 is rotatably installed inside the annular groove 104. A crossbar 106 is fixedly connected to the inner wall of the annular block 105. The crossbar 106 and the pre-set limiting groove 107 inside the threaded rod 102 achieve a sliding fit, ensuring the anti-disengagement connection of the threaded rod 101 and the threaded rod 102 without affecting the rotation of the threaded rod 101 and the threaded rod 102. The upper and lower ends of the limiting groove 107 are both closed, and the inner wall of the limiting groove 107 is attached to the outer wall of the crossbar 106 to achieve a sliding connection between the upper and lower parts.

[0030] By independently rotating threaded rod 101 and threaded rod 102, they separate from upper threaded block 8 and lower threaded block 9. After replacing elastic element 7 and upper threaded block 8 and lower threaded block 9 which are fixedly connected to elastic element 7, the linkage assembly 10 can be reused. At the same time, the movement of threaded rod 101 and threaded rod 102 is restricted by crossbar 106 and limiting groove 107, ensuring that no individual parts in the linkage assembly 10 will fall off. This also allows elastic element 7 to be quickly removed for inspection and maintenance. Only one rotation is needed to drive upper threaded block 8 and lower threaded block 9 to rotate synchronously for disassembly and assembly, ensuring smoother use of the yarn guide seat.

[0031] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
