[0002] Polyester yarn refers to the cotton yarn used to produce polyester. The polyester yarn is reeled after transmission and further processed uniformly after reeling. The existing polyester yarn conveying device generally winds the yarn on a reel through a machine. During the winding process, the yarn is not neat enough due to being too loose, which will cause the yarn to come off, affecting the conveying efficiency.

[0003] The existing authorized publication number CN217263911U discloses an anti-de-line polyester yarn conveying device, which is intended to solve the problem of de-line during polyester yarn conveying. The key points of its technical solution are: an anti-de-line polyester yarn conveying device, including a group of support frames arranged relatively, a winding device is arranged between the support frames, a crossbeam is arranged between a group of support frames, the crossbeam is fixedly connected to the support frames, a sliding plate is slidably connected to the crossbeam, a conveying roller is rotatably connected to the sliding plate, a pressing piece is arranged on the sliding plate, the pressing piece is located above the conveying roller and the pressing piece reciprocates along the length direction of the sliding plate. The utility model drives the pressing piece to contact the conveying roller through the cylinder fixedly connected to the sliding plate, thereby constraining the polyester yarn passing through the conveying roller to achieve the purpose of preventing de-line.

[0004] The above-mentioned existing solutions have the following problems: the anti-unthreading polyester yarn conveying device presses the yarn into the conveying roller by pressing, but the pressing piece lacks a guiding structure, and the yarn is not tensioned during the transmission process, resulting in unthreading. At the same time, the conveying roller is not easy to replace. Long-term use will affect the yarn conveying process and reduce the yarn transmission efficiency. Utility Model Content

[0027] Specifically, the connecting component 4 includes a connecting frame 41, a lifting rod 42 and an insertion rod 43. The upper end of the connecting frame 41 is fixedly connected to the moving mechanism 2, the lower end of the lifting rod 42 is fixedly connected to the tensioning mechanism 5, the upper part of the lifting rod 42 is slidably connected in the connecting frame 41, the insertion rod 43 is slidably connected in the connecting frame 41, one end of the insertion rod 43 is plugged into the lifting rod 42, and a pull plate 46 is provided at the other end of the insertion rod 43, and a handle 45 is provided on the pull plate 46. Pulling the handle 45 drives the pull plate 46 and the insertion rod 43 to move outward, and brings the insertion rod 43 out of the range of the slot 47, and releases the fixed limit of the lifting rod 42, so that the lifting rod 42 can be moved up and down, thereby adjusting the tensioning mechanism to a suitable use position.

[0028] Specifically, a plurality of slots 47 are provided at longitudinal intervals on the lifting rod 42, and the slots 47 are matched with the insertion rod 43, so that the lifting rod 42 can be adjusted to different heights. At the same time, the connection is firm, the lifting rod 42 will not slip, and the stability is improved.

[0029] Specifically, a first spring 44 is sleeved on the outer side of the insertion rod 43, and the first spring 44 is arranged between the lifting rod 42 and the pull plate 46. When the insertion rod 43 moves to a position corresponding to the slot 47, the elastic force of the first spring 44 is converted into a thrust force, inserting the slot 43 into the slot 47.

[0030] Specifically, a motor 6 is provided on one side of the support frame 1, and two groups of fixing rings 8 are symmetrically provided on both sides of the winding roller 3, wherein one group of fixing rings 8 is fixedly connected to the output end of the motor 6, and the motor 6 is started to drive the winding roller 3 to rotate, so that the winding roller 3 can be wound normally.

[0031] Specifically, a fixing rod 10 is threadedly connected to the support frame 1, one end of the fixing rod 10 is fixedly connected to another set of fixing rings 8 by a fastening bolt 7, and a rotating plate 9 is provided at the other end of the fixing rod 10.

[0033] When the device is in use, the yarn Figure 5 As shown, the yarn goes from the top of the first set of tensioning wheels 58 to the bottom of the second set of tensioning wheels 58, and is finally wound on the winding roller 3. The yarn passes through the tensioning wheels 58, driving the slider 56 to slide along the slide rod 54 in the fixed frame 57. At this time, the slider 56 squeezes the second spring 55, and the second spring 55 provides elastic force to achieve tensioning of the yarn.

[0034] The connecting assembly 4 and the tensioning mechanism 5 are driven by the moving mechanism 2 to perform linear reciprocating motion, so that the yarn transmitted through the tensioning wheel 58 is evenly wound onto the winding roller 3.

[0035] When it is necessary to adjust the upper and lower heights of the tensioning mechanism 5, the handle 45 is pulled to drive the pull plate 46 and the insertion rod 43 to move outward, and the insertion rod 43 is moved out of the range of the slot 47, and the fixed limit of the lifting rod 42 is released, so that the lifting rod 42 can be moved up and down, and the insertion rod 43 presses the first spring 44 when it moves outward. When the insertion rod 43 moves to the position corresponding to the slot 47, the elastic force of the first spring 44 is converted into thrust, and the slot 43 is inserted into the slot 47, so that the tensioning mechanism is adjusted to a suitable use position. At the same time, it is also convenient to disassemble and replace the tensioning mechanism 5 as a whole to prevent damage to the tensioning mechanism 5 from affecting the yarn conveying process, thereby causing derailment.

[0036] When the winding roller 3 needs to be disassembled and replaced, the fastening bolt 7 is turned out to release the fixed connection to the fixing rod 10, and the fixing rod 10 is moved away from the fixing ring 8 through the movable plate 9, so that the winding roller 3 is disassembled and replaced.
