Description

Technical Field

[0001] This utility model relates to the field of yarn guide technology, specifically a yarn guide to prevent yarn entanglement. Background Technology

[0002] The yarn guide on the yarn rack of a circular knitting machine has the functions of guiding and pressing the yarn. Short fiber yarn is more suitable for conventional yarn clamps, but filament or short fiber yarn with high twist may get tangled on the yarn clamp during the transmission process due to yarn slack when the machine stops or airflow generated by the fan, resulting in yarn breakage.

[0003] In the prior art, patent application CN202121608539.7 discloses a yarn guide to prevent yarn entanglement, including a support rod, an upper pressure yarn disc, a lower pressure yarn disc, a mounting plate fixed to the upper end of the support rod, an inlet yarn guide plate, and an outlet yarn guide cone. The inlet yarn guide plate and the outlet yarn guide cone are respectively fixed to both ends of the mounting plate, the upper pressure yarn disc and the lower pressure yarn disc are located in the middle of the mounting plate, the inlet yarn guide plate is provided with a first yarn-passing hole, the outlet yarn guide cone is conical, the small-diameter end of the outlet yarn guide cone has an end plate, the end plate has a second yarn-passing hole, and the large-diameter end of the outlet yarn guide cone faces outward. This utility model has the advantages of avoiding yarn entanglement and breakage.

[0004] However, in the existing yarn guide technology, when the yarn passes through the first and second yarn-passing holes on the surfaces of the inlet yarn guide plate and the outlet yarn guide cone, the yarn will rub against the hole walls, causing the yarn to fray or even break. Utility Model Content

[0005] The purpose of this invention is to provide a yarn guide to prevent yarn entanglement, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a yarn guide to prevent yarn entanglement, comprising: a yarn inlet guide plate, a yarn through hole on the surface of the yarn inlet guide plate, a rubber protective sleeve movably inserted into the yarn through hole, a fixed baffle fixed at one end of the yarn inlet guide plate, a guide rail fixed at the other end of the yarn inlet guide plate, a movable baffle slidably connected on the surface of the guide rail, and the fixed baffle and the movable baffle respectively abutting against two symmetrical end faces of the rubber protective sleeve.

[0007] Preferably, the guide rails are provided in two sets, which are symmetrically distributed about the threading hole. The bottom ends of the two sets of guide rails are fixed with the same set of base plates, and the top ends of the base plates are fixed with baffle springs. The top ends of the baffle springs are fixed to the bottom ends of the movable baffle.

[0008] Preferably, a limiting plate mounting hole is formed on the surface of the guide rail, one end of the limiting plate is movably inserted into the limiting plate mounting hole, and the other end of the limiting plate extends out of the limiting plate mounting hole and is positioned below the movable baffle.

[0009] Preferably, the top of the limiting plate is provided with a slope.

[0010] Preferably, a sleeve is fixed on the surface of the yarn feeding guide plate, and a pull rod hole is opened at the end of the sleeve away from the guide rail, and a pull rod is movably inserted into the pull rod hole.

[0011] Preferably, one end of the pull rod is fixed to the surface of the limiting plate, and the other end of the pull rod extends out from the pull rod hole.

[0012] Preferably, a limiting plate spring is sleeved on the rod body of the pull rod, with one end of the limiting plate spring abutting against the surface of the limiting plate and the other end of the limiting plate spring abutting against the inner wall of the sleeve.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The yarn guide proposed in this utility model for preventing yarn entanglement has rubber protective sleeves installed in the yarn-passing holes on the surfaces of the yarn-in guide plate and the yarn-out guide cone. The rubber protective sleeves are held in the middle by a fixed baffle and a movable baffle, thus being more securely installed in the yarn-passing holes. When the yarn passes through the yarn-passing holes, the rubber protective sleeves separate the yarn from the inner wall of the yarn-passing holes, preventing friction between the yarn and the inner wall of the yarn-passing holes. When friction occurs between the yarn-passing holes and the rubber protective sleeves, because the rubber protective sleeves are very soft, more wear occurs on the rubber protective sleeves, thus protecting the yarn and preventing it from fuzzing or breaking. Simultaneously, when the rubber protective sleeves are severely worn, pressing down on the movable baffle allows the old rubber protective sleeve to be removed from the yarn-passing holes, and a new rubber protective sleeve to be installed back into the yarn-passing holes. Then, releasing the movable baffle allows the baffle spring to push the movable baffle back to its original position under its own elasticity, thus achieving the replacement of the rubber protective sleeves.

[0021] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Example 1: Please refer to Figures 1 to 5 This utility model provides a technical solution: a yarn guide to prevent yarn entanglement, comprising: a yarn inlet guide plate 1, a yarn through hole 2 on the surface of the yarn inlet guide plate 1, a rubber protective sleeve 3 movably inserted into the yarn through hole 2, a fixed baffle 4 fixed at one end of the yarn inlet guide plate 1, a guide rail 5 fixed at the other end of the yarn inlet guide plate 1, a movable baffle 6 slidably connected on the surface of the guide rail 5, the fixed baffle 4 and the movable baffle 6 respectively abutting against two symmetrical end faces of the rubber protective sleeve 3, two sets of guide rails 5 are provided, the two sets of guide rails 5 are symmetrically distributed about the yarn through hole 2, the bottom ends of the two sets of guide rails 5 are fixed with the same set of base plates 7, the top end of the base plate 7 is fixed with a baffle spring 8, and the top end of the baffle spring 8 is fixed to the bottom end of the movable baffle 6.

[0023] In actual use, rubber protective sleeves 3 are installed in the threading holes 2 on the surfaces of the yarn inlet guide plate 1 and the yarn outlet guide cone. The rubber protective sleeves 3 are held in place by a fixed baffle 4 and a movable baffle 6, thus ensuring a more secure installation in the threading holes 2. When the yarn passes through the threading holes 2, the rubber protective sleeves 3 separate the yarn from the inner wall of the threading holes 2, preventing friction between the yarn and the inner wall. When friction occurs between the threading holes 2 and the rubber protective sleeves 3, because the rubber protective sleeves 3 are very soft, more wear occurs on the rubber protective sleeves 3, thereby protecting the yarn and preventing wear. If the rubber protective sleeve 3 becomes frayed or broken, and the yarn is pulled out of the threading hole 2, then the movable baffle 6 is pressed down. The movable baffle 6 moves down along the guide rail 5, causing it to move away from one end of the rubber protective sleeve 3. At this time, the baffle spring 8 is compressed by the movable baffle 6 and the base plate 7. Then the old rubber protective sleeve 3 can be taken out of the threading hole 2, and the new rubber protective sleeve 3 can be installed back into the threading hole 2. After that, the movable baffle 6 is released, and the baffle spring 8 pushes the movable baffle 6 back to its original position under its own elasticity, thus realizing the replacement of the rubber protective sleeve 3.

[0024] Example 2: Based on Example 1, in order to maintain the height of the movable baffle 6 after it is pressed down to a height lower than the yarn threading hole 2 when the rubber protective sleeve 3 is replaced, a limit plate mounting hole 9 is opened on the surface of the guide rail 5. One end of the limit plate 10 is movably inserted into the limit plate mounting hole 9, and the other end of the limit plate 10 extends out of the limit plate mounting hole 9 and is set below the movable baffle 6. The top of the limit plate 10 is provided with an inclined surface. A sleeve 11 is fixed on the surface of the yarn feeding guide plate 1. A pull rod hole 14 is opened at the end of the sleeve 11 away from the guide rail 5. A pull rod 12 is movably inserted into the pull rod hole 14. One end of the pull rod 12 is fixed on the surface of the limit plate 10, and the other end of the pull rod 12 extends out of the pull rod hole 14. A limit plate spring 13 is sleeved on the rod body of the pull rod 12. One end of the limit plate spring 13 abuts against the surface of the limit plate 10, and the other end of the limit plate spring 13 abuts against the inner wall of the sleeve 11.

[0025] When the movable baffle 6 is pressed downwards, its bottom end slides across the inclined surface of the limiting plate 10, thereby pushing the limiting plate 10 into the limiting plate mounting hole 9 and the sleeve 11. At this time, the limiting plate spring 13 is compressed. When the top end of the movable baffle 6 is lower than the bottom end of the threading hole 2, the top end of the movable baffle 6 is also lower than the bottom end of the limiting plate mounting hole 9. Then, under its own elasticity, the limiting plate spring 13 pushes the limiting plate 10 back to its original position, thereby causing the bottom of the limiting plate 10 to... The end is placed against the top of the movable baffle 6, and then the movable baffle 6 can be released, so that the movable baffle 6 is maintained at a height lower than the yarn hole 2 without manual support; at the same time, after the rubber protective sleeve 3 is replaced, the pull rod 12 is pulled out of the pull rod hole 14, and the pull rod 12 drives the limit plate 10 to move in the same direction, so that the limit plate 10 retracts back into the limit plate mounting hole 9 and the sleeve 11, and then the movable baffle 6 can return to its original position under the push of the baffle spring 8.

[0026] In actual use, rubber protective sleeves 3 are installed in the threading holes 2 on the surfaces of the yarn inlet guide plate 1 and the yarn outlet guide cone. The rubber protective sleeves 3 are held in the middle by the fixed baffle 4 and the movable baffle 6, thus being more securely installed in the threading holes 2. When the yarn passes through the threading holes 2, the rubber protective sleeves 3 separate the yarn from the inner wall of the threading holes 2 to prevent the yarn from rubbing against the inner wall of the threading holes 2. When the threading holes 2 rub against the rubber protective sleeves 3, because the rubber protective sleeves 3 are very soft, more wear occurs in the threading holes 2. The rubber protective sleeve 3 protects the yarn, preventing it from fraying or breaking. When the rubber protective sleeve 3 becomes severely worn, first pull the yarn out of the threading hole 2, then press the movable baffle 6 downwards. The movable baffle 6 moves downwards along the guide rail 5, causing it to move away from one end of the rubber protective sleeve 3. At this time, the baffle spring 8 is compressed by the movable baffle 6 and the base plate 7. Then, the old rubber protective sleeve 3 can be removed from the threading hole 2, and the new rubber protective sleeve 3 can be installed back into the threading hole 2. Finally, release the movable baffle. 6. The baffle spring 8, under its own elasticity, pushes the movable baffle 6 back to its original position, thus enabling the replacement of the rubber protective sleeve 3. When the movable baffle 6 is pressed downwards, its bottom end slides across the inclined surface of the limiting plate 10, thereby pushing the limiting plate 10 into the limiting plate mounting hole 9 and the sleeve 11. At this time, the limiting plate spring 13 is compressed. When the top end of the movable baffle 6 is lower than the bottom end of the yarn hole 2, the top end of the movable baffle 6 is also lower than the bottom end of the limiting plate mounting hole 9. Then, the limiting plate spring 13, under its own elasticity, will... The limiting plate 10 is pushed back to its original position, so that the bottom end of the limiting plate 10 abuts against the top end of the movable baffle 6. Then the movable baffle 6 can be released, so that the movable baffle 6 is maintained at a height below the yarn hole 2 without manual support. At the same time, after the rubber protective sleeve 3 is replaced, the pull rod 12 is pulled out of the pull rod hole 14. The pull rod 12 drives the limiting plate 10 to move in the same direction, so that the limiting plate 10 retracts back into the limiting plate mounting hole 9 and the sleeve 11. Then the movable baffle 6 can return to its original position under the push of the baffle spring 8.
