DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Example 1

[0020] Reference Figure 1-4A polyester fiber extrusion molding device includes a bottom plate 5, a support leg 12 is fixedly connected to the bottom plate 5, a shell 1 is fixedly connected to the support leg 12, a feeding mechanism includes a metering pump 3, a connecting pipe 2 is connected to the feed end of the metering pump 3, the discharge end of the metering pump 3 is connected to the shell 1 through a conduit, the connecting pipe 2 is connected to an external molten PET storage device, the molten PET is drawn into the shell 1 through the metering pump 3, and is molded through a spinneret 4.

[0021] The lower end of the shell 1 is opened, and a feeding mechanism is arranged on the shell 1. A movable plate 8 is connected to the bottom plate 5 through a fixing mechanism. A rotating shaft 9 is rotatably connected to the movable plate 8 through a bearing. A plurality of spinnerets 4 are fixedly connected to the rotating shaft 9 at equal distances on the circumference. The inner diameters of the forming holes of the plurality of spinnerets 4 are all different. The rotating shaft 9 is rotated by a rotating mechanism, and the rotating mechanism drives the rotating shaft 9 to rotate, so that the spinnerets 4 with forming holes of different inner diameters are abutted against the lower end of the shell 1, so as to produce polyester fibers of different diameters, thereby improving the applicability of the device. At the same time, since the spinneret 4 can be rotated to be exposed, the spinneret 4 can be cleaned.

[0022] The rotating mechanism includes a telescopic rod 10, which is fixedly connected to the moving plate 8. A rack 11 is fixedly connected to the telescopic rod 10, and a gear 14 is fixedly connected to the rotating shaft 9. The gear 14 is meshed with the rack 11. The telescopic rod 10 is extended to drive the rack 11 to move, thereby driving the gear 14 to rotate, so that the rotating shaft 9 rotates. When the telescopic rod 10 stops, the rack 11 will stop, so that the rack 11 fixes the gear 14, thereby ensuring that the position of the spinneret 4 does not change.

[0023] When in use, the telescopic rod 10 is extended to drive the rack 11 to move, thereby driving the gear 14 to rotate, so that the rotating shaft 9 rotates, the spinneret 4 with different inner diameter molding holes abuts against the lower end of the shell 1, and the metering pump 3 draws the molten PET into the shell 1 and is molded through the spinneret 4.

[0024] Example 2

[0025] In Example 1, when the interior of the housing 1 needs to be cleaned, due to the arrangement of multiple spinnerets 4, the spinnerets 4 are blocked and the lower end of the housing 1 cannot be completely exposed. Figure 1-4 As another preferred embodiment of the utility model, on the basis of embodiment 1, the fixing mechanism includes a connecting frame 7, the connecting frame 7 is fixedly connected to the movable plate 8, a positioning rod 15 is penetrated by the connecting frame 7, and a handle is fixedly connected to the positioning rod 15 so as to play a grasping role and drive the positioning rod 15 to move.

[0026] A positioning sleeve 16 is sleeved on the outer side of the positioning rod 15, and the positioning sleeve 16 is fixedly connected to the bottom plate 5. By pulling the positioning rod 15 out of the positioning sleeve 16, the fixation of the movable plate 8 will be released, so that the movable plate 8 will slide on the slide rod 6, which is conducive to moving the spinneret 4 completely out of the lower end of the shell 1 and cleaning the inside of the shell 1.

[0027] A slide bar 6 is provided through the movable plate 8 , and the slide bar 6 is fixedly connected to the bottom plate 5 . The slide bar 6 is designed so as to push the movable plate 8 to slide on the slide bar 6 .

The support block 13 is designed to support the spinneret 4, so as to prevent the upper end of the spinneret 4 from bearing too heavy a load, affecting the connection effect between the spinneret 4 and the rotating shaft 9, and causing the spinneret 4 to fall off.
