[0166] Winding film mechanism

[0167] According to an embodiment of the present invention, the main components of the film wrapping mechanism 35 are as follows: Figure 11 , Figure 12As shown. In this embodiment, the working principle of the wrapping film mechanism 35 is as follows: when the finished thread pulling mechanism 32 passes through the central hole of the wrapping film mechanism 35 and hooks the thread bundle on the left and right disc wrapping mechanism 11, it is pulled backward to a set distance. Then, the thread shaping gripper 3506 is driven by the upper and lower gripper displacement cylinders (3507 and 3511 in the figure are the installation positions of the upper and lower gripper displacement cylinders) to clamp the thread bundle. The left and right limit gripper cylinders 3510 also clamp the thread bundle. Then, the film cutting mechanism 34, which can be used to cut the film, is clamped and moved backward to the rear positioning. The film winding motor reducer 3501 drives the film winding transmission gear 3502 to drive the packaging film 3504 to wind 2 turns. Then, the upper and lower clamping plates 3402 and 3403 of the film cutting mechanism 34 are opened to release the film head. At the same time, the finished thread pulling mechanism 32 pulls the thread bundle and moves backward at the set speed. Under the drive of the film winding motor reducer 3501, the packaging film 3504 also winds the thread bundle at a constant speed at the set speed.

[0168] Film cutting mechanism

[0169] According to an embodiment of the present invention, the main components of the film-cutting mechanism 34 are as follows: Figure 13 As shown. Its general structure and working principle are described below.

[0171] Finished wire pulling-out mechanism

[0172] According to an embodiment of the present invention, the main components of the finished yarn pulling mechanism 32 are as follows: Figure 15 , Figure 16 As shown. Its general structure and working principle are described below.

[0173] A high-precision slide consisting of a servo motor reducer 321, a toothed belt linear module 322, and a linear guide rail 323 drives the wire drawing head assembly 324 to move, achieving excellent results in precise positioning and uniform wire drawing. The main structure of the wire drawing head assembly 324 is shown below. Figure 16Its main function is to hook the thread and shape the thread head. When one of the discs of the left and right disc winding mechanism 11 is fully wound with thread and moves to the center position, and the servo motor reducer 321 drives the thread drawing head assembly 324 to move forward and pass through the center hole of the winding film mechanism 35, the thread core shaft insertion cylinder 3246 is activated to open the thread insertion shaft 3243. At this time, the thread drawing head assembly 324 moves forward again until the edge of the disc exceeds the thread, and the thread core shaft insertion cylinder 3246 reverses to close the thread insertion shaft 3243 and hook the thread. Then, the servo motor reducer 321 drives the thread drawing head assembly 324 to move backward and pull out the thread. At the same time, the thread shaping cylinder 3244 is activated to push the thread shaping block 3241 to press the thread head, thereby achieving the purpose of shaping.

[0174] Head waste removal mechanism

[0175] like Figure 14 As shown in the figure, according to an embodiment of the present invention, the main components of the head waste removal mechanism 33 are as shown in the figure. Its general structure and working principle are described below.

[0176] When the finished thread pulling mechanism 32 feeds the film-wrapped thread bundle forward and cuts it into sections until only the thread ends remain (e.g., about 8cm), the waste material clamp 3301 actuates, driving the left and right waste material needle plates 3303 to pierce the thread end packaging film (without clamping the thread end). Then, the thread insertion shaft 3243 of the thread pulling assembly 324 releases, and the thread end falls off. At this point, the film covering the thread end has been pierced and clamped by the waste material needle plates 3303, thus achieving the separation effect between the thread and the film. Preferably, a thread end storage container can be provided at the position where the thread end falls. Subsequently, the waste material clamp displacement rodless cylinder 3304 actuates, moving the film covering the thread end above the film waste guide nozzle 3709. Then, the two film ejection cylinders 3302 and 3306, respectively located behind the corresponding waste material needle plates, actuate simultaneously to eject the packaging film. The waste material clamp 3301 opens, and the packaging film falls into the film waste container.

[0177] Guiding mechanism

[0178] According to an embodiment of the present invention, the main components of the guide mechanism 31 are as follows: Figure 17 As shown. Its general structure and working principle are described below.

[0179] When a finished yarn product passes overhead, the guide wheel vertical displacement cylinder 312 will activate, raising the yarn V-shaped guide wheel 311. The main function of this structure is to support the yarn bundle, ensuring the smoothness, consistency, and stability of the yarn bundle's operation.

[0180] Finished wire cutting mechanism

[0181] According to an embodiment of the present invention, the main components of the wire cutting mechanism 37 are shown in Figure 18. Figure 19 As shown. In this embodiment, the configuration of the wire cutting positioning mechanism can be seen, for example, in [reference needed]. Figure 19 As shown. Its general structure and working principle are described below.

[0182] Once the finished thread pulling mechanism 32 pulls out all the thread at a uniform speed and wraps it with film to its subsequent positioning, the system automatically enters the finished thread cutting program. First, the first cut cuts the tail of the finished thread. The limit block displacement cylinders 3705 and 3713 actuate, respectively pushing the thread-cutting rear limit block 3704 and the thread-cutting front limit block 3710 to merge into a circular cutter holder at the center position. Then, the limit positioning cylinder 3712 actuates, extending a pin to completely lock the thread-cutting front limit block 3710. Next, the system triggers the start-up cutting motor 3701, which, through the reducer 3702, drives the rocker arm 3714 to move vertically up and down. The cutting circular blade 3703 mounted on the rocker arm 3714 cuts the finished thread. After each movement, the cutting circular blade 3703 returns to its high position and stops.

[0183] After the first cut cuts the tail of the thread, the system enters the fixed-length cutting mode set by the system.

[0184] First, the finished thread pulling mechanism 32 moves the finished thread bundle forward to the set length and stops. Then, the cutting motor 3701 restarts, driving the cutting circular blade 3703 to cut the finished thread. This process is repeated until the system calculates and determines that the last section of the thread bundle is not long enough. The remaining thread is then treated as a thread end. Finally, the limit positioning cylinder 3712 retracts its pin, releasing the lock on the thread cutting pre-cut limit block 3710. The limit block displacement cylinders 3705 and 3713 then retract, respectively, to the thread cutting post-cut limit block 3704 and the thread cutting pre-cut limit block 3710. The entire cutting process is complete.

[0185] Tail waste removal mechanism

[0186] According to an embodiment of the present invention, the main components of the tail material removal mechanism 38 are as follows: Figure 20 As shown. Its general structure and working principle are described below.

[0187] When the finished yarn cutting mechanism 37 cuts the tail of the finished yarn, the tail material removal mechanism 38 works in conjunction to remove and separate the tail yarn and the wrapping waste. Before the finished yarn cutting mechanism 37 makes the first cut to the tail of the finished yarn, the tail material clamping displacement cylinder 3804 is activated, causing the entire tail material pneumatic clamp 3801 to move directly above the tail of the finished yarn. Then, the tail material pneumatic clamp 3801 is activated to drive the left and right waste needle plates 3802 and 3806 to pierce the yarn tail wrapping and clamp the tail of the finished yarn (not tightly). After the finished wire cutting mechanism 37 cuts the finished wire tail, the waste wire tail falls into the wire waste container directly below. At this time, the film-coated waste wire tail is still pierced and stuck by the left and right waste needle plates 3802 and 3806. Then, the tail material clamp displacement cylinder 3804 reverses its action, causing the entire tail material pneumatic clamp 3801 to move back to directly above the inlet of the film-coated waste container. Then, the tail material film ejection cylinders 3805 on both sides simultaneously push out the packaging film, the tail material pneumatic clamp 3801 opens, and the packaging film falls into the film-coated waste container. At this point, the entire process is complete.

[0188] Wire cutting and packaging station pneumatic system

[0189] According to an embodiment of the present invention, the main components of the pneumatic system 40 at the thread cutting and packaging station are as follows: Figure 21 As shown. In this embodiment, the pneumatic system is mainly used to control the movement of each cylinder during the subsequent winding, wrapping, and cutting processes.

[0195] When the equipment is started, it automatically detects the output speed of the wire drawing extruder and automatically lays out and winds up the filaments according to the speed parameter.

[0196] After a dual-station servo turntable winding system completes one roll, the servo cable routing device quickly switches to another station;

[0197] The pneumatic fingers on the dual-station servo turntable winding system grip the entire roll of yarn and rotate it to directly above the wheel cutting system, which then moves laterally to complete the cutting.

[0198] The finished product combing system clamps the cut product threads and presses them with combing wheels, rotating them and moving them along the turntable's arc groove to the front of the robot arm in the turntable packaging system;

[0199] The rotary packaging system automatically rotates in conjunction with a robotic arm to complete the wrapping process.

[0200] When the winding and packaging reaches the set length, the fixed-length cutting system cuts the wound thread product, completing the full automated cutting process.

[0201] According to one embodiment of the automatic thread cutting and packaging equipment of the present invention, advanced intelligent automated equipment and technology for high-speed packaging, cutting, and waste sorting of flexible thread materials are provided. The developed thread cutting technology and high-speed rotating blades are used to cut loose threads. Developed technologies such as cam mechanisms and punching shears are used to quickly cut bundled threads, achieving neat cuts without damaging the threads.

[0202] According to one embodiment and a preferred process flow, the filament sequentially passes through a filament storage mechanism and a filament feeding and winding mechanism to reach a left and right disc rotating mechanism, where the filament produced by the injection molding machine is wound onto the left and right discs. Then, an automated filament feeding and cutting mechanism cuts the edge of the filament between the left and right discs; and then a filament cutting mechanism cuts the filament on the discs.

[0203] According to a preferred embodiment, the filament on the winding station can be pulled out by the finished filament pulling mechanism, and the pulled-out filament can be packaged by the wrapping film mechanism. Furthermore, the packaged filament can be cut into finished filament products of a fixed length by the finished filament cutting mechanism. According to another embodiment, the waste material can be moved to a waste bin using a tail material removal mechanism and a head waste material removal mechanism, respectively.

[0204] Through the above-described scheme and concept of the present invention, the present invention enables highly automated winding, cutting, and packaging of yarn.

[0205] The foregoing description of several embodiments of the invention has been presented for illustrative purposes.
