By utilizing the cooperation of a limiting ring, connecting cylinder, limiting post, sliding plate, fixing frame, connecting rod and shielding ring on the surface of a fixed shaft, the shielding ring, limiting ring and connecting cylinder limit the position of the guide wheel or adjusting wheel, the limiting post limits the position of the connecting cylinder, and the connecting rod pulls the limiting post to disengage from the connecting cylinder, which facilitates the installation and disassembly of the guide wheel and adjusting wheel, and makes it easy to independently disassemble the guide wheel and adjusting wheel for maintenance or replacement.
[0004] However, the following problems exist when implementing the above technical solutions: In the above device, the guide wheel's position is limited by a related structure set on the surface of the fixed shaft. The blocking ring and the limiting post in the above position limiting device are in a relatively fixed position on the surface of the fixed shaft, and thus the distance between the blocking ring and the limiting post is relatively fixed. Due to different design requirements for the fabric, there will be yarns of different sizes during the production of covered yarn, and corresponding guide wheels need to be used. When using this device, if a guide wheel of a different size is replaced, the fixed shaft or a connecting cylinder of a different width needs to be replaced accordingly.

[0033] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.
[0034] like Figures 1 to 6 As shown in the figure, the covering yarn guiding device for producing double crepe fabric provided in this embodiment of the utility model includes several fixed shafts 1 disposed on the surface of a support plate.
[0035] It should be noted that the fixed shaft 1 can be slidably or fixedly mounted on the surface of the support plate;
[0036] Each fixed shaft 1 is internally equipped with an adjustment mechanism, the adjustment mechanism comprising:
[0037] The spacer block 21 and the positioning block 22 are slidably disposed inside the fixed shaft 1. A plurality of protruding rods 23 are fixedly connected to the surface of the spacer block 21. A plurality of blocking rods 24 are slidably connected inside the positioning block 22. The blocking rods 24 and the protruding rods 23 all penetrate the fixed shaft 1. The opposing surfaces of the blocking rods 24 and the protruding rods 23 are in contact with the guide wheel.
[0038] Two sliding racks 25, one of which is fixedly connected to the spacer block 21, and the other sliding rack 25 is slidably disposed on the surface of the positioning block 22. A drive gear 26 is rotatably connected inside the fixed shaft 1. The drive gear 26 meshes with the two sliding racks 25, and the two sliding racks 25 are symmetrically arranged relative to the drive gear 26.
[0039] A movable component is disposed between the positioning block 22 and the fixed shaft 1. The movable component is rotatably disposed inside the positioning block 22 and slidably disposed inside the fixed shaft 1.
[0040] In summary, the present invention provides a yarn guiding device for producing double crepe fabric, comprising a spacer block 21, a positioning block 22, a sliding rack 25, and a drive gear 26. The spacer block 21 and the positioning block 22 are provided with a protruding rod 23 and a blocking rod 24 penetrating a fixed shaft 1. Through the contact between the protruding rod 23 and the blocking rod 24 and the guide wheel, the guide wheel is confined between the protruding rod 23 and the blocking rod 24, thus fixing the relative position of the guide wheel and the fixed shaft 1. The sliding rack 25 and the drive gear 26 can simultaneously push the spacer block 21 and the positioning block 22 to slide, facilitating quick fixing of the guide wheel position. Simultaneously, the guide wheel can be fixed at the midpoint between the spacer block 21 and the positioning block 22, preventing the sliding yarn from contacting the support block and being affected by resistance. Furthermore, a moving component is provided between the positioning block 22 and the fixed shaft 1. This moving component allows adjustment of the position of the sliding rack 25 on the surface of the positioning block 22, enabling independent movement of the positioning block 22 and flexible adjustment of the distance between the guide wheel and the support block.
[0041] In some specific implementations, a support frame 31 is slidably connected inside the fixed shaft 1, and the drive gear 26 is rotatably disposed inside the support frame 31. A guide gear 32 is rotatably connected inside the support frame 31. The distance between the guide gear 32 and the drive gear 26 is less than the width of the sliding rack 25. A limit component is provided between the support frame 31 and the fixed shaft 1. The limit component is slidably disposed on the surface of the fixed shaft 1 and fixedly disposed on the side of the support frame 31 near the fixed shaft 1. The support frame 31 can provide a support position for the guide gear 32 and the drive gear 26 during rotation. At the same time, since the support frame 31 can move, the position of the overall guide gear 32 and the drive gear 26 can be changed, and the control position of the drive gear 26 rotation can be selected, which is convenient for maintenance and other operations. Furthermore, the guide gear 32 can ensure that the sliding rack 25 on the surface of the positioning block 22 remains in contact with the rack after sliding, and can re-engage with the drive gear 26 when reset.
[0042] In a further embodiment, a sliding groove is provided on the surface of the support frame 31. The sliding groove is adapted to the sliding rack 25, and the height of the sliding groove is equal to the maximum end face distance between the drive gear 26 and the guide gear 32. The sliding groove can limit the sliding trajectory of the sliding rack 25 on the surface of the support frame 31, and its height can ensure that the sliding rack 25 does not detach from the support frame 31 during movement.
[0043] In a further embodiment, the limiting component includes limiting teeth 33 fixedly disposed on the surface of the support frame 31, a limiting groove is formed on the surface of the fixed shaft 1, and a plurality of locking teeth 34 are fixedly connected inside the limiting groove, the locking teeth 34 being adapted to the limiting teeth 33; a connecting rod 35 is slidably connected to the surface of the support frame 31, a return spring 36 is fixedly connected between the connecting rod 35 and the support frame 31, a sliding groove is formed on the surface of the fixed shaft 1, the limiting groove and the sliding groove are symmetrically arranged relative to the support frame 31, and the sliding groove is adapted to the connecting rod 35; by using the structure of the support frame 31 on different sides in conjunction with the limiting groove and the sliding groove, the position of the support frame 31 can be fixed and the sliding trajectory restricted, while the presence of the return spring 36 can ensure that the locking teeth 34 and the limiting teeth 33 will not disengage due to external force during the contact process;
[0044] In some specific embodiments, the moving component includes a threaded rod 37 rotatably disposed inside the positioning block 22, the threaded rod 37 being threadedly connected to the sliding rack 25; by rotating the threaded rod 37, the sliding rack 25 can be made to slide vertically, changing the distance between the sliding rack 25 and the positioning block 22, thereby realizing the switching of the sliding rack 25 meshing with the drive gear 26 or the guide gear 32;
[0045] In a further embodiment, a movable shaft is fixedly connected to the end of the sliding rack 25, and a movable groove is provided on the surface of the positioning block 22. The movable shaft is adapted to the movable groove. By setting the movable groove, the sliding distance of the movable shaft can be limited, thereby limiting the sliding distance of the sliding rack 25, and further ensuring that the sliding rack 25 can make gear contact after sliding, without causing the support frame 31 to slide.
[0046] In some specific implementations, a drive ring 41 is rotatably connected inside the positioning block 22. The surface of the drive ring 41 is provided with an oblique groove 42. The direction of the oblique groove 42 is angularly deviated from the radial direction of the drive ring 41. All the blocking rods 24 are adapted to the oblique groove 42. Through the oblique groove 42, the rotation of the drive ring 41 can cause the blocking rods 24 to slide relative to the positioning block 22, thereby quickly controlling the position of all the blocking rods 24.
[0047] In a further embodiment, the end of the blocking rod 24 away from the positioning block 22 can be detachably connected to an extension rod; the external extension rod restricts the position of one side of the guide wheel, so as to avoid the blocking rod 24 applying force too low and affecting the stability of the guide wheel;
[0048] In a further embodiment, a worm gear 43 is fixedly connected to the surface of the drive ring 41, and a worm 44 is rotatably connected inside the positioning block 22. The worm gear 43 and the worm 44 are adapted to each other. By setting the worm gear 43 and the worm 44, the position of the force controlling the rotation of the drive ring 41 can be offset from the blocking rod 24, which facilitates operation.
[0049] In some specific implementations, an adjusting rod 51 is rotatably connected inside the fixed shaft 1. The adjusting rod 51 is slidably connected to the support frame 31. An adjusting conical wheel 52 is slidably connected to the surface of the adjusting rod 51. A reversing conical wheel 53 is fixedly connected to the side of the drive gear 26 away from the guide gear 32. The adjusting conical wheel 52 meshes with the reversing conical wheel 53. The direction of force can be changed by the reversing conical wheel 53 and the adjusting conical wheel 52, which facilitates operation.
[0050] In a further embodiment, the adjusting rod 51 has a toothed groove on its surface, and the fixed shaft 1 has a sliding tooth 54 slidably connected to its surface. The sliding tooth 54 is adapted to the toothed groove, and a compression spring 55 is fixedly connected between the sliding tooth 54 and the fixed shaft 1. The rotation of the adjusting rod 51 can be restricted by the toothed groove and the sliding tooth 54, and the rotation of the drive gear 26 can be restricted by the reversing cone wheel 53 and the adjusting cone wheel 52, so as to prevent the positioning block 22 and the spacer block 21 from changing their positions.
[0051] The working principle of this utility model:
[0052] When changing the position of the support frame 31, first press the support frame 31 to cause the limiting tooth 33 and the locking tooth 34 to disengage, slide the support frame 31, and change the position of the drive gear 26.
[0053] When adjusting the position of the positioning block 22 individually, rotate the threaded rod 37 to change the position of the sliding rack 25 on the surface of the positioning block 22. The sliding rack 25 contacts the guide gear 32, and the threaded rod 37 can be slid.
[0054] When the positions of the spacer block 21 and the positioning block 22 are changed simultaneously, the sliding moving tooth 54 is disengaged from the tooth groove. The adjusting rod 51 is rotated, and the rotation of the adjusting rod 51 causes the adjusting cone wheel 52 to rotate, which drives the reversing cone wheel 53 to rotate, thereby driving the gear 26 to rotate. The two sliding racks 25 slide simultaneously, changing the positions of the spacer block 21 and the positioning block 22. After the positions are determined, the moving tooth 54 can be reset.
[0055] When fixing the guide wheel, first slide the guide wheel into contact with the spacer block 21. Change the position of the positioning block 22 through the above operation, or change the positions of the positioning block 22 and the spacer block 21 at the same time. After the positioning block 22 slides to the appropriate position, rotate the worm gear 44. The worm gear 44 drives the worm wheel 43 to rotate, causing the drive ring 41 to rotate, which drives the blocking rod 24 to move. The blocking rod 24 is ready after it is in contact with the guide wheel.
[0056] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
