Description

Technical Field

[0001] This utility model relates to the field of polyester filament production technology, and in particular to a quick roll-changing device for polyester filament production. Background Technology

[0002] Polyester filament is made from polyester fibers. The production process for polyester filament is diverse, and can be categorized by polyester raw material into direct melt spinning and chip spinning. Direct spinning involves feeding the melt from the polymerization reactor directly into a spinning machine for spinning. Chip spinning involves melting the polyester melt obtained from the polycondensation process into chips using a screw extruder after casting, pelletizing, and pre-spinning drying, followed by spinning. During the production process, a winding device is needed to wind the finished polyester filament onto paper rolls for subsequent processing and use. Once a certain thickness of polyester filament roll has been wound onto the paper roll, it needs to be removed from the winding device before a new paper roll is placed on top. The simplicity and convenience of the polyester filament rewinding process are closely related to the efficiency of polyester filament rewinding, and also affect the production and winding efficiency of polyester filament. Therefore, in order to achieve high efficiency in polyester filament production and winding, a quick rewinding device for polyester filament production is needed. Utility Model Content

The return spring is fixedly mounted on the inner end of the mounting rod. The handle is fixedly mounted on the outer end of the mounting rod.

[0006] Preferably, the transmission assembly is mounted on the equipment housing, and a motor is fixedly mounted on the upper end of the equipment housing, with the output shaft of the motor connected to the transmission assembly.

[0007] Preferably, the base shaft on the rotating assembly is fixedly connected to the output shaft of the transmission assembly, the outer end of the base shaft is provided with a storage groove, and two second guide grooves are symmetrically provided on the outer wall of the base shaft, the second guide grooves are connected to the storage groove.

[0008] Preferably, the collar of the rotating assembly has a plurality of first guide grooves symmetrically formed thereon, and the first guide grooves penetrate through the collar inside and out.

[0009] Preferably, the connecting rod on the movable fixing member is movably installed in the first guide groove opened on the collar, the two sets of rollers are respectively located on the inner and outer sides of the collar, and the iron arc-shaped base plate and the iron inclined baffle are both located on the outer side of the collar.

[0010] Preferably, the magnetic cone tube on the limiting component is movably sleeved on the base shaft, and the magnetic cone tube is simultaneously located inside several movable fixing parts.

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, a quick-change device for polyester filament production includes a rotating assembly 4, which is fixedly mounted on the output shaft of a transmission assembly 3. The rotating assembly 4 consists of a base shaft 7 and a collar 8. The collar 8 is fixedly sleeved on the base shaft 7, and several movable fixing parts 5 are movably mounted in a ring on the collar 8. Each movable fixing part 5 consists of an iron arc-shaped base plate 12, a connecting rod 13, rollers 14, and iron inclined baffles 15. The connecting rod 13 is fixedly mounted on the inner end of the iron arc-shaped base plate 12. There are two sets of rollers 14, both of which are rotatably mounted on the connecting rod 13. The iron inclined baffles 15 are fixedly mounted on the inner wall of the iron arc-shaped base plate 12. The base shaft 7... A limiting component 6 is installed, consisting of a magnetic tapered tube 16, connecting plates 17, mounting rods 18, a return spring 19, and a handle 20. Two connecting plates 17 are symmetrically fixed to the inner wall of the magnetic tapered tube 16. The mounting rod 18 is fixedly installed at the inner ends of the two connecting plates 17. The return spring 19 is fixedly installed at the inner end of the mounting rod 18. The handle 20 is fixedly installed at the outer end of the mounting rod 18. A transmission component 3 is installed on the equipment housing 1. A motor 2 is fixedly installed at the upper end of the equipment housing 1. The output shaft of the motor 2 is connected to the transmission component 3. When winding the polyester filament, a paper tube used for winding and carrying the polyester filament can be sleeved. Polyester filaments are wound onto several movable fixing parts 5. When the winding device is started, the motor 2 drives the rotating component 4 to rotate via the transmission component 3. The rotating component 4 then drives the movable fixing parts 5 and the paper tube to rotate. At this time, the rotating paper tube can wind the polyester filaments onto the paper tube. After a certain thickness of polyester filament roll is wound onto the paper tube, the paper tube with the polyester filament roll needs to be removed from the several movable fixing parts 5. Then, a new paper tube is placed on the several movable fixing parts 5. The method is to first pull the magnetic cone tube 16 outward through the handle 20, the mounting rod 18, and the connecting plate 17. At this time, the magnetic cone tube 16... Under the magnetic force, several movable fixing parts 5 will move towards the base shaft 7, at which point the paper tube will be released. Then, the paper tube with the polyester filament can be removed from the several movable fixing parts 5. Then, a new paper tube is placed on the several movable fixing parts 5. Finally, the handle 20, the mounting rod 18, the connecting plate 17, and the magnetic cone tube 16 are released. Under the elastic force of the return spring 19, the handle 20, the mounting rod 18, the connecting plate 17, and the magnetic cone tube 16 will move inward to reset. Then, the magnetic cone tube 16 will push the several movable fixing parts 5 outward, away from the base shaft 7. At this time, the movable fixing parts 5 will fix the paper tube.

[0020] Finally, by setting the rotating component 4, the moving fixing component 5 and the limiting component 6, the paper tube can be placed on several moving fixing components 5 to wind up the polyester filament. The rotating component 4, the moving fixing component 5 and the limiting component 6 work together to make the changing of the polyester filament roll simple and convenient, and to make the changing of the polyester filament roll efficient, thus making the production and winding efficiency of the polyester filament high.

[0021] Furthermore, the base shaft 7 on the rotating assembly 4 is fixedly connected to the output shaft of the transmission assembly 3. A receiving groove 10 is provided at the outer end of the base shaft 7. Two second guide rail grooves 11 are symmetrically provided on the outer wall of the base shaft 7. The second guide rail grooves 11 are connected to the receiving groove 10. Several first guide rail grooves 9 are symmetrically provided on the collar 8 on the rotating assembly 4. The first guide rail grooves 9 pass through the collar 8 inside and out. The connecting rod 13 on the movable fixing member 5 is movably installed in the first guide rail groove 9 on the collar 8. Two sets of rollers 14 are located on the inner and outer sides of the collar 8, respectively. The iron arc-shaped base plate 12 and the iron inclined baffle 15 are both located on the outer side of the collar 8. The magnetic cone tube 16 on the limiting assembly 6 is movably sleeved on the base shaft 7. The magnetic cone tube 16 is also located on the inner side of several movable fixing members 5. At the same time, the magnetic cone tube 16 can be attracted together with the iron arc-shaped base plate 12 and the iron inclined baffle 15. The connecting plate 17 is slidably installed in the second guide rail groove 11. The mounting rod 18 is located inside the storage groove 10, the handle 20 is located on one side of the base shaft 7, and the return spring 19 is fixedly connected to the inner wall of the storage groove 10. The paper tube used for winding polyester filament can be sleeved on the iron arc-shaped base plate 12 on several movable fixing parts 5. When it is necessary to release the fixing of the paper tube, the magnetic cone tube 16 can be pulled outward by the handle 20, the mounting rod 18 and the connecting plate 17. At this time, the return spring 19 will be stretched and deformed by the mounting rod 18. As the magnetic cone tube 16 moves outward, the movable fixing part 5 will slide towards the base shaft 7 under the magnetic force of the magnetic cone tube 16, and the fixing of the paper tube will be released. When it is necessary to fix the paper tube, simply release the handle 20. At this time, under the elastic force of the return spring 19, the handle 20, the mounting rod 18, the connecting plate 17 and the magnetic cone tube 16 will move inward. Thus, under the push of the magnetic cone tube 16, the limiting component 6 will move away from the base shaft 7, and finally the paper tube will be fixed.
