Description

Technical Field

[0001] This utility model belongs to the field of polyester POY production technology, and in particular relates to a guide structure for polyester POY production. Background Technology

[0002] POY production is a crucial step in polyester filament spinning. The guiding structure's role is to smoothly and with minimal damage guide the filaments from the spinneret, through cooling and oiling, and finally to a uniform winding head. The guiding structure is used primarily in polyester POY production to reduce fuzz and breakage in the polyester POY yarn, ensuring the quality of the yarn package and its physical properties.

[0003] A search revealed a polyester thread guiding structure in patent document CN220578610U. The structure includes a bracket with a lifting groove at the top center. A first lifting frame is positioned to the left of the lifting groove, and a lifting block is positioned to the right of the first lifting frame. The lifting block is located within the lifting groove. A locking structure consisting of a locking pin and several locking slots, combined with the elastic force of a spring, ensures a more stable connection between the lifting mechanism and the bracket after height adjustment. This avoids the loosening that can occur with traditional screw-locking methods, preventing changes in device height and affecting normal use. A pull rope structure allows the locking pin to retract into a positioning assembly, facilitating height adjustment of the first and second lifting frames on the bracket. Furthermore, once the locking pin is fully retracted into the positioning assembly, the first and second lifting frames can be easily disassembled for maintenance or replacement of the left-side guiding mechanism.

[0004] However, the existing polyester thread guiding structure still has the following shortcomings in practical use: 1. First, a connecting rod is connected to the guide ring, and a connecting ring is fixed to the lower end of the connecting rod. The connecting ring is fixed to the rotating rod. When the number of polyester threads is less than the number of guide rings, some guide rings will be idle and underutilized. When the number of polyester threads is more than the number of guide rings, it is not possible to guide all polyester threads sufficiently. However, the connecting ring is fixed to the rotating rod, which is inconvenient to disassemble and assemble, and it is difficult to increase or decrease the number of guide rings according to the number of polyester threads. 2. Secondly, a movable plate is installed on the side wall of the support, and a rotating rod is set above the movable plate. The rotating rod is rotatably connected to the movable plate. A guide ring is set on the outer wall of the rotating rod. The polyester thread is passed through the guide ring, so that the guide ring guides the polyester thread. However, the guide ring is stationary relative to the polyester thread, which will increase the friction between the polyester thread and the guide ring, aggravate the wear of the polyester thread, and reduce the production quality of the polyester thread.

[0005] To address these issues, we provide a guiding structure for polyester POY production. Utility Model Content

[0006] The purpose of this utility model is to provide a guide structure for polyester POY production. By setting up a disassembly and assembly component, it is convenient to disassemble and assemble the movable frame. The movable frame can be increased according to the needs of polyester POY production to avoid insufficient or surplus guide components. Furthermore, by setting up the guide component, the polyester POY and the rotating roller rotate simultaneously, which transforms the yellow friction between the yarn and the guide roller into rolling friction, effectively reducing wear and solving the technical problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a guide structure for polyester POY production, comprising a crossbeam with a rectangular array of positioning holes on the crossbeam.

[0009] The present invention is further configured such that symmetrical grooves are provided on both sides of the crossbeam, and sliders are symmetrically fixed on the two inner walls of the movable frame, the sliders being slidably connected in the grooves.

[0010] The present invention is further configured such that a sleeve fixed to the outer circumference of the ring is sleeved on the outside of the return spring, and the sleeve abuts against the movable frame.

[0013] The present invention is further configured such that a positioning rod is fixedly connected to the upper end of the side rod, the positioning rod passes through the upper rod, and screws are symmetrically threaded on the side wall of the upper rod, the screws being threaded onto the positioning rod.

[0014] This utility model has the following beneficial effects: 1.

[0022] Example 2 Please see Figure 1 and Figure 4Based on the first specific embodiment, a disassembly and assembly component 2 is provided. The disassembly and assembly component 2 includes a handle 201, a ring 202, a return spring 203, and a movable frame 206.

[0023] Example 3 Please see Figure 1 , Figure 2 and Figure 5 Based on specific embodiments one and two, a guide assembly 3 is provided. The guide assembly 3 includes a mounting frame 301, a connecting frame 302, a pin 303, a lower rod 306, a side rod 307, an upper rod 308, and a rotating roller 309. The rotating roller 309 is rotatably connected to the periphery of the lower rod 306, the side rod 307, and the upper rod 308, so that the rotating roller 309 rotates during the movement of the polyester POY. The rotating roller 309 and the polyester POY rotate relative to each other, which transforms the yellow friction between the yarn and the guide roller into rolling friction, effectively reducing wear and improving the production quality of polyester POY. Specifically, the mounting frame 301 is mounted on the movable frame 206. A connecting frame 302 is mounted on the pivot pin 303 inside the mounting frame 301. A lower rod 306 is installed inside the connecting frame 302. Side rods 307 are symmetrically connected to the lower rod 306. An upper rod 308 is connected to both side rods 307. Rollers 309 are rotatably connected to the periphery of the lower rod 306, side rods 307 and upper rod 308. Furthermore, a mounting plate 305 is installed on the crossbeam 1. A rotating rod 304 is connected through the side wall of the mounting plate 305. A sliding rod 304a is symmetrically fixed to the side wall of the rotating rod 304. The pin 303 has symmetrically opened grooves at the top and bottom. The sliding rod 304a is slidably connected in the groove. The screw 304b threaded to the end of the rotating rod 304 abuts against the side wall of the mounting plate 305. A connecting rod 307a is fixed to the lower end of the side rod 307. The connecting rod 307a is threaded to the lower rod 306. A positioning rod 307b is fixed to the upper end of the side rod 307. The positioning rod 307b passes through the upper rod 308. Screws 307c are symmetrically threaded to the side wall of the upper rod 308. The screws 307c are threaded to the positioning rod 307b. The operation process of this embodiment is as follows: During the production of polyester POY, the take-up roller rotates to take in the polyester POY. During the movement of the polyester POY, an external force is applied to the rotating roller 309, causing the rotating roller 309 to rotate simultaneously, thereby guiding the polyester POY. When it is necessary to adjust the angle of the rotating roller 309, the screw 304b is rotated counterclockwise to release the fixed position of the rotating rod 304. Rotating the rotating rod 304 causes the slide rod 304a to rotate accordingly, driving the pin 303 to rotate, causing the connecting frame 302 to rotate around the pin 303, adjusting the tilt angle of the rotating roller 309. Then, the screw 304b is rotated clockwise to fix the position of the rotating rod 304.
