Description

Technical Field

[0001] The utility model relates to the technical field of wire merging machines, and particularly to a wire winding mechanism of a wire merging machine. Background Technique

[0002] A wire merging machine is a machine device that winds filaments around a certain workpiece. According to the actual processing and production requirements, the wire winding mechanism is an important part of the wire merging machine. During the production process of antibacterial polyester drawn texturing yarn, a wire merging machine is required to merge polyester drawn texturing yarn and antibacterial yarn and then wind them on a bobbin.

[0003] The prior patent document with the publication number of CN220723122U discloses a wire winding machine with an anti-slip function. When the wire cannot be wound, the torque will increase beyond the set torque value, causing the torque limiter to slip and idle, and the wire winding disc will not be driven to rotate for wire winding operations, thus avoiding the situation of damaging the wire. By moving the mounting block to wind the wire, the wire winding can be carried out more evenly, preventing the occurrence of quality problems. By directly moving the wire winding disc, the removal or replacement operation can be carried out, making it more convenient.

[0004] Although the above-mentioned wire winding machine with an anti-slip function can solve the corresponding technical problems, it realizes the reset and positioning operations of the connecting column and the limit insertion block connected thereto through the elastic force of the spring. However, the spring will show the phenomenon of elastic fatigue after long-term use, making the subsequent connection between the limit insertion block and the wire winding disc unstable, thereby reducing the installation firmness of the wire winding disc, and thus having a certain impact on the subsequent wire winding operations. Therefore, a wire winding mechanism of a wire merging machine is proposed. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example 1

[0026] See also Figures 1-5 A winding mechanism of a doubling machine, comprising a support shell 1, a winding drum 2, a supporting mechanism 3 for supporting the winding drum 2, a wire guiding mechanism 4 for guiding polyester low-elastic yarn, a displacement mechanism 5 for driving the wire guiding mechanism 4 to reciprocate left and right, and a driving mechanism 6 for driving the winding drum 2 and the local structure of the displacement mechanism 5 to rotate, the supporting mechanism 3, the wire guiding mechanism 4 and the displacement mechanism 5 are arranged on one side of the support shell 1 from top to bottom, the winding drum 2 is arranged on the supporting mechanism 3, and the driving mechanism 6 is arranged in the inner cavity of the support shell 1;

[0027] Among them, the supporting mechanism 3 includes a hollow rod 31 which is horizontally movable and arranged on one side of the supporting shell 1. The winding drum 2 is sleeved on the surface of the hollow rod 31. The inner cavity of the hollow rod 31 is equipped with an electric telescopic rod 32. The electric telescopic rod 32 is powered by a battery, which avoids the problem of needing to power the electric telescopic rod through wires as much as possible. The output end of the electric telescopic rod 32 is fixedly connected to a movable rod 33. The surface of the movable rod 33 is threadedly connected with a screw sleeve 34, and one side of the screw sleeve 34 is in contact with one end of the winding drum 2.

[0028] Working principle: By starting the electric telescopic rod 32, the output end of the electric telescopic rod 32 drives the electric telescopic rod 32 to move horizontally, thereby being able to adjust the distance between the hollow rod 31 and the electric telescopic rod 32. At this time, according to the length of the winding cylinder 2 and the required number of winding cylinders 2 to be used, the electric telescopic rod 32 is moved to an appropriate position; when using one winding cylinder 2, the blocking member 35 and the winding cylinder 2 are sequentially sleeved on the surface of the hollow rod 31, so that the protrusion 353 on the blocking member 35 aligns with the groove 36 on the electric telescopic rod 32 and the hollow rod 31 and slides in until the blocking member 35 moves to one end of the hollow rod 31 close to the support shell 1. One end of the winding cylinder 2 is clamped to the snap ring 352, and the other end of the winding cylinder 2 is located on the movable rod 33. Then, the screw sleeve 34 is screwed onto the surface of the movable rod 33 to limit and support the winding cylinder 2; when using two winding cylinders 2, one of the blocking members 35, one of the winding cylinders 2, the other blocking member 35, and the other winding cylinder 2 are sequentially sleeved on the hollow rod 31. Finally, the screw sleeve 34 is screwed onto the surface of the movable rod 33 to synchronously limit and support the two winding cylinders 2; the antibacterial polyester drawn texturized yarn to be wound is passed through the wire guide base 42 and fixed on the surface of the winding cylinder 2. The dual-axis motor 61 is started, and one output shaft of the dual-axis motor 61 drives the hollow rod 31, the electric telescopic rod 32, the movable rod 33, the screw sleeve 34, the blocking member 35, and the winding cylinder 2 to rotate synchronously through the torque limiter 62, thereby being able to wind the antibacterial polyester drawn texturized yarn; at the same time, the other output shaft of the dual-axis motor 61 drives the reciprocating lead screw 52 to rotate, the reciprocating lead screw 52 drives the reciprocating nut 53 to reciprocate along its surface, and the reciprocating nut 53 drives the T-shaped frame 41, the wire guide base 42, and the antibacterial polyester drawn texturized yarn to reciprocate synchronously, thereby enabling the antibacterial polyester drawn texturized yarn to be evenly wound on the surface of the winding cylinder 2.

[0029] Beneficial effects: By holding the hollow rod 31 or the winding cylinder 2 and rotating the screw sleeve 34, the screw sleeve 34 can be removed from the movable rod 33. At this time, the winding cylinder 2 can be loaded and unloaded. There is no need to use a spring, which not only eliminates the phenomenon of spring fatigue under long-term use, improves the stability during the assembly of the support mechanism 3, ensures the subsequent winding effect of the antibacterial polyester drawn texturized yarn, but also simplifies the overall structure of the support mechanism 3, facilitating installation and subsequent maintenance and repair operations; by the electric telescopic rod 32, the distance between the hollow rod 31 and the movable rod 33 can be adjusted, enabling the support mechanism 3 to support winding cylinders 2 of different lengths or determine the number of winding cylinders 2 on the hollow rod 31. This not only helps to increase the applicable range of this winding mechanism but also improves the winding efficiency of the antibacterial polyester drawn texturized yarn, meeting the requirements of large-scale winding production.

[0030] Embodiment 2

[0031] Please refer to Figures 1-5 , the winding mechanism of a doubling machine provided in this embodiment is different from that in Embodiment 1 in that:

[0032] A blocking member 35 for limiting the end of the winding cylinder 2 is provided on the surface of the hollow rod 31. The number of the blocking members 35 is the same as that of the winding cylinders 2. The blocking member 35 includes a retaining ring 351 movably sleeved on the surface of the hollow rod 31. A clamping ring 352 capable of clamping to one end of the winding cylinder 2 is fixedly connected to one side of the retaining ring 351 facing the screw sleeve 34. A limiting member is provided between the clamping ring 352 and the hollow rod 31. The above design can cooperate with the screw sleeve 34 to limit the two ends of the winding cylinder 2 to ensure the stability of the winding cylinder 2 during rotation and improve the wire winding effect. At the same time, when two winding cylinders 2 and blocking members 35 are sleeved on the hollow rod 31, the blocking members 35 can space the two winding cylinders 2.

[0033] Further, the limiting member includes grooves 36 opened on the surfaces of the hollow rod 31 and the movable rod 33. Protrusions 353 slidably connected to the inner cavities of the grooves 36 are integrally formed in the inner cavities of the retaining ring 351 and the clamping ring 352. The central axes of the hollow rod 31, the electric telescopic rod 32, the movable rod 33, the retaining ring 351, the clamping ring 352, and the winding cylinder 2 are all on the same straight line. The above design can enable the blocking member 35 and the winding cylinder 2 to rotate synchronously when the hollow rod 31 rotates, avoiding the phenomenon of idling of the hollow rod 31.

[0034] Specifically, the wire guiding mechanism 4 includes a T-shaped frame 41 located obliquely below the hollow rod 31. Both sides of the top of the T-shaped frame 41 are fixedly connected with wire guiding seats 42.

[0035] It should be noted that the structure of the above wire guiding seat 42 is the composition structure of an installation block, a longitudinal pulley, and a transverse pulley in a wire winding machine with an anti-slip function disclosed in the existing publication number CN220723122U. During the wire winding operation, it reduces the resistance generated by the up and down, left and right amplitudes, effectively increases the convenience of the wire winding operation movement, and is the prior art. Therefore, it will not be described in detail in this technical solution.

[0036] Further, the displacement mechanism 5 includes a protective shell 51 fixedly connected to one side of the support shell 1. One side of the inner cavity of the protective shell 51 is horizontally rotatably connected with a reciprocating lead screw 52 through a bearing. A reciprocating nut 53 is sleeved on the surface of the reciprocating lead screw 52. The bottom end of the T-shaped frame 41 movably penetrates into the inner cavity of the protective shell 51 and is fixedly connected to the top of the reciprocating nut 53. The above design can drive the wire guiding mechanism 4 to horizontally reciprocate along the axial direction of the reciprocating lead screw 52 when the reciprocating lead screw 52 rotates, and then drive the polyester drawn texturized yarn to move synchronously through the wire guiding mechanism 4, making the wire winding more uniform.

[0037] Further, the protective shell 51 is located below the T-shaped frame 41, and a through groove 511 for the T-shaped frame 41 to slide is opened at the top of the protective shell 51. The above design can not only provide a moving space for the T-shaped frame 41 but also play a guiding role for the T-shaped frame 41, enabling the T-shaped frame 41 to stably move horizontally.

[0038] Further, the driving mechanism 6 includes a double-shaft motor 61 installed at the bottom of the inner cavity of the support housing 1. A torque limiter 62 is installed at the top of the inner cavity of the support housing 1. One end of the reciprocating lead screw 52 movably penetrates into the inner cavity of the support housing 1 and is fixedly connected to one of the output shafts of the double-shaft motor 61. One end of the hollow rod 31 movably penetrates into the inner cavity of the support housing 1 and is connected to the output end of the torque limiter 62. The other output shaft of the double-shaft motor 61 and the input end of the torque limiter 62 are connected by belt pulley and belt for cooperative transmission. The above design can drive the support mechanism 3 and the reciprocating lead screw 52 to rotate synchronously without using multiple motors, achieving the effect of energy saving and power saving.

[0039] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
