Description

Technical Field

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

[0002] Twisting polyester yarn can enhance its strength and abrasion resistance, improve its elasticity and elongation, and reduce pilling. When twisting polyester yarn, a twisting device is required. Existing twisting devices mainly include a rotatable hollow spindle, a guide hook, and other components. In use, the yarn bobbin needs to be fixed to the hollow spindle, and then the yarn is passed through the hollow spindle. The guide component then guides the yarn through the hollow spindle. Because the existing structure for fixing the yarn bobbin and the guide component for guiding the yarn are separate, the overall structure of the equipment is not compact enough, and mutual obstruction can easily occur during use, affecting the convenience of use.

[0018] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0019] like Figure 1-6As shown, a polyester twisting device includes a mounting frame 3, a rotating shaft 4 mounted on the mounting frame 3, a through groove 5 with openings at both ends inside the rotating shaft 4, the two ends of the through groove 5 being located at the upper end and the side of the rotating shaft 4 respectively, a driving part for driving the rotating shaft 4 to rotate on the mounting frame 3, a tray 6 mounted on the rotating shaft 4, a fixing block 7 mounted on the tray 6, a stud 8 threadedly connected to the fixing block 7, two guide rings 9 at one end of the stud 8, a clamping block 10 mounted on the tray 6, two guide rods 11 slidably connected to the fixing block 7 on one side of the clamping block 10, a stop block 12 at one end of the guide rod 11, and a limiting part mounted on the mounting frame 3.

[0020] When performing a 2x twist on polyester yarn, the yarn bobbin 1, with polyester yarn 2 wound on it, needs to be installed onto the rotating shaft 4 first. The yarn bobbin 1 includes a core cylinder and polyester yarn 2 wound around the core cylinder. The inner diameter of the core cylinder is slightly larger than the outer diameter of the rotating shaft 4. Here, the inner diameter of the core cylinder is 25mm, and the outer diameter of the rotating shaft 4 is 24mm. After the yarn bobbin 1 is fitted onto the rotating shaft 4, the two guide rings 9 drive the stud 8 to rotate. The stud 8 screws into the threaded part of the fixing block 7, pushing the clamping block 10 and squeezing the core cylinder. The guide rod 11 enables the clamping block 10 to maintain linear movement. After the clamping block 10 has finished squeezing the core cylinder, the yarn bobbin 1 is fixed onto the rotating shaft 4. Then, the polyester yarn 2 on the yarn bobbin 1 is released, so that the polyester yarn 2 first enters the through groove 5 from the upper end of the rotating shaft 4, and then exits from the rotating shaft 4. The side wall draws the polyester filament 2 out from the through groove 5. The lower end of the through groove 5 is set in a slope shape so that the polyester filament 2 can be drawn out from the lower end of the through groove 5. Then the polyester filament 2 passes through the nearest guide ring 9 and then through the limiting part. Then the drive part drives the rotating shaft 4 to rotate. The yarn bobbin 1, the guide ring 9 and the drawn polyester filament 2 on the rotating shaft 4 all rotate with the rotating shaft 4, thereby realizing the twisting of the polyester filament 2. During the twisting process of the polyester filament 2, there is also an external winding device. The winding device continuously winds up the twisted polyester filament 2, so that the polyester filament 2 on the yarn bobbin 1 can be continuously released. When the polyester filament 2 on the yarn bobbin 1 is used up, a new yarn bobbin 1 can be replaced.

[0021] The twist of polyester yarn 2 is controlled by controlling the winding speed of the external winding equipment.

[0022] The guide ring 9 is made of metal and is welded to the stud 8.

[0023] Furthermore, the drive unit includes a motor 13 mounted on the mounting bracket 3, and meshing gears 14 are respectively provided on the output end of the motor 13 and on the rotating shaft 4.

[0024] After the motor 13 starts, it can drive the rotating shaft 4 to rotate through the meshing transmission of the gear 14 on its output end and the gear 14 on the rotating shaft 4, thereby driving the yarn drum 1 to rotate and realize the twisting of the polyester yarn 2. The motor 13 is controlled by the PLC system.

[0025] Furthermore, a counterweight 15 is provided at the lower end of the rotating shaft 4 to improve the stability of the rotating shaft 4 during rotation.

[0026] Furthermore, the limiting part includes two support plates 16 disposed on the upper surface of the mounting bracket 3, and also includes a horizontal plate 17. A through hole is opened in the middle of the horizontal plate 17. One end of the horizontal plate 17 is rotatably connected to one of the support plates 16. A semi-circular groove is opened at the other end of the horizontal plate 17. An upright plate 18 is disposed on the other support plate 16. A through mounting groove is opened inside the upright plate 18. An elastic band 19 is installed on one side of the upright plate 18. A locking rod 20 is disposed on one side of the elastic band 19. One end of the locking rod 20 is set in a semi-circular shape.

[0027] The elastic band 19 can be a flexible rubber sheet, silicone sheet, or nylon band. The clamping rod 20 is fixed to the side of the elastic band 19 with glue. When it is necessary to install the wire spool 1 onto the rotating shaft 4, the distance between the horizontal plate 17 and the rotating shaft 4 is relatively short. If the height of the wire spool 1 is too high, it cannot be effectively placed. Therefore, it is necessary to first move the horizontal plate 17 away from the top of the rotating shaft 4 and push the horizontal plate 17 to rotate. One end of the horizontal plate 17 will squeeze the clamping rod 20 and deform the elastic band 19. At this time, the clamping rod 20 disengages from the groove on the horizontal plate 17, and the horizontal rod can be removed from the rotating shaft 4, which allows for convenient... Install the yarn spool 1 onto the rotating shaft 4. After the yarn spool 1 is installed, rotate the horizontal plate 17 in the opposite direction. The horizontal plate 17 will first contact and squeeze the clamping rod 20, causing the elastic band 19 to deform. When the groove moves to one side of the end of the clamping rod 20, the end of the clamping rod 20 is pushed into the groove under the action of the elastic band 19. After the horizontal plate 17 is adjusted, the polyester yarn 2 passing through the guide ring 9 needs to pass through the through hole on the horizontal plate 17. The through hole on the horizontal plate 17 can limit the range of motion of the polyester yarn 2 at the horizontal plate 17, so that the subsequent winding equipment can easily and stably wind the twisted polyester yarn 2.

[0028] Furthermore, a spring 21 is fitted onto the guide rod 11, and the spring 21 is located between the fixed block 7 and the stop block 12.

[0029] After all the polyester yarn 2 on the yarn spool 1 has been released, only the core tube remains on the rotating shaft 4. At this time, by rotating the stud 8 in the opposite direction, the stud 8 is moved away from the rotating shaft 4. The spring 21 pushes the stop block 12 to move away from the rotating shaft 4, and at the same time drives the clamping block 10 to move away from the rotating shaft 4, so that the clamping block 10 is separated from the core tube. Then the core tube is removed from the rotating shaft 4, and then a new yarn spool 1 is installed on the core tube.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
