Description

Technical Field

[0001] This utility model relates to the field of winding technology, specifically a polyester filament winding device. Background Technology

[0002] Polyester filament is made from polyester fibers. Polyester is an important type of synthetic fiber and is the commercial name for polyester fiber in my country. It is a fiber-forming polymer—polyethylene terephthalate—obtained from purified terephthalic acid or dimethyl terephthalate and ethylene glycol through esterification or transesterification and polycondensation reactions. The fiber is then spun and post-processed. Polyester filament is a filament with a length of over one kilometer. Polyester filament needs to be wound up during the production process.

[0003] For example, Chinese utility model patent CN219823230U discloses a winding device for filament-staple fiber composite spinning, including a base, a support frame on the upper left side of the base, a groove at the bottom of the crossbar of the support frame, a slider slidably connected to the groove, a rotating rod on the support frame, the rotating rod being threadedly connected to the slider, a guide roller at the bottom of the slider, the output end of a micro motor being connected to the rear end of the rotating rod, a support plate on the upper right side of the base, a winding roller sleeve on the outer side of the inner roller, and a quick-release assembly including a groove at the front of the inner roller, a limiting member slidably connected to the groove, and multiple springs evenly arranged on the groove, the other ends of the multiple springs being connected to the upper inner side of the limiting member. This allows users to quickly detach the winding roller sleeve from the inner roller, thereby removing the wound filament-staple fiber composite yarn from the winding roller sleeve, facilitating user operation.

[0004] However, existing polyester filament winding devices require adjustments to the drum size based on market demand and transportation convenience, making it inconvenient to install and fix winding drums of different widths.

[0005] Therefore, we propose a polyester filament winding device to solve the above problems. Utility Model Content

[0024] Example 1:

[0025] Please see Figure 1-6 This is the first embodiment of the present invention.

The other end of the rotating rod 3 is fixedly connected to a fixed rotating shaft 4. A limiting ring plate 5 is fixedly connected to the outer surface of the fixed rotating shaft 4. A limiting protrusion 6 is fixedly connected to the top of the fixed rotating shaft 4. A limiting groove 71 is opened on the inner top surface of the winding drum 7. The limiting groove 71 is slidably connected to the limiting protrusion 6, which can perform preliminary limiting when installing the winding drum 7.

[0026] A connecting frame 8 is fixedly connected to one side of the fixed frame 1. A motor 9 is fixedly installed on one side of the connecting frame 8. One end of a lead screw 10 is fixedly connected to the shaft of the motor 9. The other end of the lead screw 10 is rotatably connected to the connecting frame 8. A sliding groove 81 is opened on one side of the connecting frame 8. A slider 11 is slidably connected in the sliding groove 81. A threaded sleeve 111 is embedded in the slider 11. The threaded sleeve 111 is threadedly connected to the lead screw 10. A moving block 12 is fixedly connected to one side of the slider 11. A slot 121 is opened on one side of the moving block 12. An electric push rod 13 is fixedly installed on the top and bottom surfaces of the slot 121. One end of a connecting rod 14 is fixedly connected to the output end of the electric push rod 13. A sliding block 15 is fixedly connected to the other end of the connecting rod 14. A sliding block 15 is slidably connected to the slot 121 on one side of the sliding block 15. A limiting semi-ring plate 16 is fixedly connected to one side of the sliding block 15. The limiting semi-ring plate 16 contacts the outer surface of the fixed rotating shaft 4. Motor 2 is connected to an external power source. By driving motor 2, the rotating rod 3 and the fixed rotating shaft 4 are rotated. The winding drum 7 is limited by the limiting protrusion 6, which can drive the winding drum 7 to rotate for winding. When the winding drum 7 needs to be disassembled after winding, motor 9 is started to drive the lead screw 10 to rotate, which drives the slider 11, the moving block 12 and the two limiting semi-ring plates 16 to move to their original positions. Then, the electric push rod 13 is started to drive the two limiting semi-ring plates 16 to move away from each other, disengage from the fixed rotating shaft 4 and leave enough space to pull out the wound winding drum 7, which is convenient for disassembly and assembly.

[0027] Example 2:

[0028] Please see Figure 1-6 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The outer surface of the fixed rotating shaft 4 is slidably connected to the winding drum 7, and the limiting ring plate 5 is fixedly connected to one side of the limiting protrusion 6.

[0029] The lead screw 10 is rotatably connected to the slide groove 81.

[0030] There are two limiting semi-ring plates 16, and the two limiting semi-ring plates 16 are in contact with each other on their closest sides. There are two sliding blocks 15, and the two sliding blocks 15 are in contact with each other on their closest sides.

[0031] Limiting blocks 151 are fixedly connected to both sides of the sliding block 15. Limiting grooves 1211 are opened at both ends of the groove 121. The limiting blocks 151 are slidably connected to the limiting grooves 1211, which can limit the movement range of the sliding block 15, thereby limiting the movement range of the limiting semi-ring plate 16.

[0032] One side of the take-up drum 7 contacts the limiting ring plate 5, and the other side of the take-up drum 7 contacts the limiting half-ring plate 16.

[0033] Please see Figure 1-6In use, the limiting groove 71 on the winding drum 7 can be slid into the limiting protrusion 6 on the fixed rotating shaft 4, so that one side of the winding drum 7 abuts against the limiting ring plate 5. The two electric push rods 13 adopt a dedicated electric push rod synchronous controller, which is a common technology in this field and will not be described in detail in this application. There are dedicated electric push rod synchronous controllers on the market. Through the built-in control algorithm and sensor feedback, the extension speed and position of the two electric push rods can be precisely controlled to ensure their synchronous operation. This method has high precision and stability. Then, the sliding block 15 and the limiting semi-ring plate can be driven by driving the electric push rods 13. 16 moves, and the two limiting semi-ring plates 16 move closer to each other, so that the two limiting semi-ring plates 16 are in contact with each other on their closest sides and the two limiting semi-ring plates 16 are in contact with the fixed rotating shaft 4. The motor 2 9 is connected to an external power supply. Then, according to the width of the installed take-up drum 7, the drive motor 2 9 drives the lead screw 10 to rotate, which drives the slider 11, the moving block 12, the two limiting semi-ring plates 16, etc. to move horizontally. The two limiting semi-ring plates 16 slide horizontally on the fixed rotating shaft 4, so that the two limiting semi-ring plates 16 abut against one side of the take-up drum 7, and cooperate with the limiting protrusion 6 and the limiting ring plate 5, which can facilitate the installation, limiting and fixing of take-up drums 7 of different widths.
