TECHNICAL FIELD

[0002] The polylactic acid plant-dyed yarn is prepared by using polylactic acid fiber as a dyeing material. After the polylactic acid plant-dyed yarn is formed, a yarn winding machine is used to uniformly wind the polylactic acid plant-dyed yarn. Before the yarn winding operation of the polylactic acid plant-dyed yarn is performed, a winding drum is sleeved on a winding roller of the yarn winding machine. The yarn winding machine is started to control the winding roller to rotate together with the winding drum. The polylactic acid plant-dyed yarn on a yarn arranging roller of the yarn winding machine is wound onto the winding drum to collect the yarn. The yarn is dyed with polylactic acid plant dye, which changes the fiber structure and state of the yarn, and changes the temperature and humidity sensitivity of the yarn. The polylactic acid plant-dyed yarn is wound on the winding drum to form a layered cylindrical structure. The dyed yarn wound on the winding drum is pressed and constrained in the inner region of the yarn roll. The continuous winding of the winding drum gradually increases the winding diameter of the polylactic acid plant-dyed yarn roll, which weakens the contact and exchange of the yarn constrained in the inner region of the yarn roll with air. During the winding and collection of the polylactic acid plant-dyed yarn, the yarn in the inner region of the yarn roll cannot be effectively separated and changed in temperature and humidity state, which cannot effectively avoid the polylactic acid plant-dyed yarn in the inner region of the yarn roll from being brittle and relaxed, and affects the winding and collection of the polylactic acid plant-dyed yarn and the subsequent storage effect.

[0028] The winding main machine 1 is connected to the winding roller 11, a thread arranging roller is connected to the upper left position of the winding roller 11, the winding main machine 1 is started to control the operation of the thread arranging roller and the winding roller 11, and the winding collection operation of the polylactic acid plant dyed yarn is performed.
[0029] The layered winding module 2 is arranged outside the winding roller 11, and the layered winding module 2 is composed of an inner mesh cylinder 21, a protrusion 22, two hollow layered hole shells 23, and eight hollow stop rods 24. The two hollow layered hole shells 23 are arranged outside the inner mesh cylinder 21 in sequence, and the diameters of the two hollow layered hole shells 23 are gradually increased. The eight hollow stop rods 24 are arranged on the inner sides of the two hollow layered hole shells 23 in a cross shape, and the hollow stop rods 24 are fixedly connected to the inner side walls of the corresponding hollow layered hole shells 23. The four protrusions 22 are arranged on the outer wall of the inner mesh cylinder 21 in a cross shape, and the protrusions 22 are fixedly connected to the inner mesh cylinder 21. The inner mesh cylinder 21 can be tightly sleeved on the outer wall of the winding roller 11 to position the two hollow layered hole shells 23 outside the winding roller 11, so that the inner mesh cylinder 21 and the two hollow layered hole shells 23 replace the winding roller 11 to perform the winding collection operation of the polylactic acid plant-dyed yarn.
[0030] Two lateral movement driving modules 4 are arranged on the winding main machine 1 and located outside the winding roller 11. The two lateral movement driving modules 4 correspond to the two hollow layered hole shells 23 respectively. The two hollow layered hole shells 23 are connected and positioned on the inner side of the winding main machine 1 through the two lateral movement driving modules 4. The lateral movement driving module 4 is composed of a lateral movement driving piece 41 and a connecting block 42. The lateral movement driving piece 41 is fixedly connected to the inner side wall of the winding main machine 1. The connecting block 42 is screwed and fixed to the output end of the lateral movement driving piece 41, so as to facilitate the fixing and separation operation of the connecting block 42 on the output end of the lateral movement driving piece 41. The lateral movement driving piece 41 is located outside the winding roller 11, so as to position the connecting block 42 outside the winding roller 11. When the lateral movement driving piece 41 is started, the connecting block 42 can move laterally outside the winding roller 11. The front end of each of the two hollow layered hole shells 23 is fixedly connected with a butt joint ring 233. The inner side wall of the connecting block 42 is fixedly connected with the front end of the corresponding butt joint ring 233.

The connecting block 42 moves laterally through the control of the lateral movement driving piece 41, so as to move laterally with the corresponding hollow layered hole shell 23 outside the winding roller 11, thereby facilitating the position adjustment and fixing operation of the hollow layered hole shell 23 outside the winding roller 11. The two hollow layered hole shells 23 are separately adjusted in position through the corresponding lateral movement driving module 4, so as to facilitate the separation and assembly operation of the two hollow layered hole shells 23 and the inner net cylinder 21. The inner net cylinder 21 and the two hollow layered hole shells 23 can sequentially perform the winding collection operation of the polylactic acid plant-dyed yarn outside the winding roller 11 in the order. The connecting block 42 is connected with the output end of the lateral movement driving piece 41 in a screwing manner, so as to facilitate the separation operation of the connecting block 42 and the lateral movement driving piece 41. When the connecting block 42 is separated from the output end of the lateral movement driving piece 41, the two hollow layered hole shells 23 can be separated from the two lateral movement driving pieces 41, so that the layered winding module 2 is separated from the two lateral movement driving modules 4. When the lateral movement driving piece 41 is started, the output end of the lateral movement driving piece 41 can be staggered with the winding roller 11 by a sufficient distance, so as to provide sufficient space for the operator to operate the layered winding module 2, thereby facilitating the taking down and replacing operation of the layered winding module 2 from the winding roller 11. The operator can conveniently and effectively perform the whole yarn winding taking down and replacing operation, thereby improving the operation efficiency.
[0031] The positioning ring 3 is arranged at the free end of the winding roller 11, and the outer wall of the positioning ring 3 is fixedly connected with a fixing block 31, the rear end of the fixing block 31 is screw-connected and fixed with the winding roller 11, and the fixing positioning ring 3 is stably installed outside the winding roller 11. The outermost abutting ring 233 is clamped and connected inside the positioning ring 3, and plays a role of positioning and reinforcing the outermost hollow layered hole shell 23. The connecting block 42 is located outside the positioning ring 3, and the positioning ring 3 limits the movement distance of the connecting block 42, so as to avoid that the connecting block 42 exceeds the movement distance.
[0032] Two guide blocks 5 are arranged outside the winding roller 11 on the yarn winding main machine 1, one fixed column 51 is arranged at the end close to the yarn winding main machine 1 of the guide block 5, the fixed column 51 is fixedly connected with the inner side wall of the yarn winding main machine 1, both the guide blocks 5 are fixedly connected with the front end of the fixed column 51, and the two guide blocks 5 are stably connected between the winding roller 11 and the yarn winding main machine 1.

The hollow layered hole shell 23 has a thread opening 231, the thread opening 231 provides space for the polylactic acid plant dyed yarn to wind on the hollow layered hole shell 23, after a certain length of polylactic acid plant dyed yarn is wound on the inner net cylinder 21 and stops rotating, the polylactic acid plant dyed yarn can pass out from the thread opening 231, so as to ensure that the yarn does not continue to wind on the inner net cylinder 21 when the winding roller 11 rotates again, thereby continuing to wind on the corresponding hollow layered hole shell 23.
[0033] Two horizontal movement driving modules 4 connect the combined layered winding module 2 at the outer side of the winding roller 11, position the layered winding module 2 at the outer side of the winding roller 11, and keep the layered winding module 2 coaxial with the winding roller 11. Two horizontal movement driving modules 4 operate to control the layered winding module 2 as a whole to move from the outer side of the free end of the winding roller 11 to the inner side of the positioning ring 3 and from the inner side of the positioning ring 3 to the winding roller 11, so that the inner net cylinder 21 is tightly sleeved on the outer side of the winding roller 11, facilitating the connection and fixing operation of the layered winding module 2 as a whole to the winding roller 11. After the inner net cylinder 21 is tightly sleeved on the outer side of the winding roller 11, two hollow layered hole shells 23 move outward together with two connecting blocks 42 when the two horizontal movement driving members 41 are started to control the two connecting blocks 42 to move outward, can move horizontally outward from the outer side of the inner net cylinder 21, effectively separate the inner net cylinder 21 from the outer side of the inner net cylinder 21, and completely expose the inner net cylinder 21 on the outer side of the winding roller 11. After the polylactic acid plant-dyed yarn is guided by two guide blocks 5, it is wound on the outer side of the inner net cylinder 21. The winding main machine 1 stops working and restarts in stages to transport the yarn in stages. In this process, when the yarn stops being transported, two hollow layered hole shells 23 are controlled by the corresponding horizontal movement driving module 4, and the connecting block 42 is controlled by the corresponding horizontal movement driving member 41 to move the corresponding hollow layered hole shell 23 to the outer side of the inner net cylinder 21. The yarn passes through the yarn passage opening 231 on the hollow layered hole shell 23 to ensure that the hollow layered hole shell 23 moves horizontally to the outer side of the inner net cylinder 21 stably, and the hollow layered hole shell 23 is positioned to replace the inner net cylinder 21 to wind the yarn. Two hollow layered hole shells 23 operate in turn to effectively layer and wind the polylactic acid plant-dyed yarn to form a layered yarn roll. The outer wall of the hollow layered hole shell 23 is fixedly connected with four support blocks 232 distributed in a cross shape, four hollow abutting rods 24 correspond to the inner side of the four support blocks 232, the lower half of the hollow abutting rod 24 protrudes from the inner side wall of the hollow layered hole shell 23, and the four protruding blocks 22 on the inner net cylinder 21 cooperate with the four hollow abutting rods 24 and the support blocks 232 on the hollow layered hole shell 23 to effectively support the yarn from multiple areas of the inner layer and the outer layer of each layer of yarn, increasing the spacing space in the yarn roll. Two through grooves 241 are formed in the outer wall of the hollow abutting rod 24, which communicate with the hollow layered hole shell 23, so that the hollow abutting rod 24 can also guide and transport external specified gas into the hollow layered hole shell 23, and the protruding block 22 can guide and transport external specified gas into the inner net cylinder 21 from the spacing area and directly release to the corresponding area of the wound yarn to improve the contact and exchange effect of the yarn and air in the inner area of the yarn roll.By controlling the gas entering and releasing at different temperatures, the yarn area separation and temperature and humidity state change of the polylactic acid plant dyed yarn in the yarn winding collection process can be effectively performed, so that the polylactic acid plant dyed yarn in the yarn winding collection process can be effectively avoided from being brittle and relaxed, the polylactic acid plant dyed yarn winding collection effect is improved, and the subsequent effective storage of the polylactic acid plant dyed yarn is facilitated, thereby improving the work efficiency.
