The wire then passes around the first transmission roller, passes through the second transmission roller and the third transmission roller, and is then fixed on the take-up roller for winding. The motor is started to drive the threaded rod to rotate, so that the movable plate moves left and right on the threaded rod, and the mounting frame drives the third transmission roller to move left and right, so that the wire guide can be evenly wound on the take-up roller.

[0004] The above device has certain drawbacks during use. When the last section of the polyester yarn passes through the guide roller, there is still a long section in the polyester winding machine. The end of this section of the polyester yarn is not fixed and is in a loose state, resulting in the third transmission roller being unable to evenly distribute this section of the polyester yarn on the take-up roller. Therefore, a wire guide device in a polyester winding machine is proposed to solve the above problem. Summary of the invention

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] Reference Figure 1 - Figure 3 The utility model provides an embodiment: a wire guide device in a polyester winding machine, comprising a box body 1, a wire feed hole 2 is opened on the side wall of the box body 1, and two sets of symmetrically arranged guide rollers 3 are rotatably connected inside the wire feed hole 2, and the guide rollers 3 are used to guide the polyester filaments from the wire feed hole 2 into the interior of the winding machine. The inner walls of the top and bottom of the box body 1 are fixedly connected with guide wheels 4, and the guide wheels 4 are used to further guide the moving direction of the polyester filaments. The inner wall of the bottom surface of the box body 1 is provided with a winding mechanism, and the winding mechanism drives the take-up roller to rotate through a motor, thereby winding the polyester filaments.

[0024] Reference Figure 1 - Figure 2 The inner wall at the top of the box 1 is provided with a guide wire assembly 5, which includes a fixed frame 51, which is fixedly connected to the inner wall at the top of the box 1, and a reciprocating screw rod 52 and a rotating shaft 53 are rotatably connected between the inner walls of the fixed frame 51, and a transmission wheel 54 is fixedly connected to the outer walls of the reciprocating screw rod 52 and the rotating shaft 53, and the two sets of transmission wheels 54 are connected by a synchronous belt 55. The reciprocating screw rod 52 and the rotating shaft 53 are synchronously moved and rotated by the transmission wheel 54 and the synchronous belt 55, and the outer wall of the reciprocating screw rod 52 is threadedly connected to a moving seat 56, and the moving seat 56 is in contact with the inner wall of the fixed frame 51, and the reciprocating screw rod 52 is used to drive the moving seat 56 and the C-shaped frame 57 to move back and forth horizontally between the inner walls of the fixed frame 51,

[0025] Reference Figure 1 - Figure 2The bottom surface of the movable seat 56 is fixedly connected with a C-shaped frame 57, and a fixed roller 58 is rotatably connected between the inner walls of the C-shaped frame 57. The fixed roller 58 is used to fit with the polyester filament. Under the action of the pressing assembly 6, the polyester filament can drive the fixed roller 58 to rotate during the winding process. The end of the fixed roller 58 is fixedly connected with a rotating wheel 59, which penetrates and is rotatably connected to the side wall of the movable seat 56, and the rotating shaft 53 penetrates and is slidably connected to the side walls of the fixed roller 58 and the rotating wheel 59. Both sides of the rotating shaft 53 are provided with raised parts, so that the rotating shaft 53 and the fixed roller 58 rotate synchronously, and the fixed roller 58 can slide along the surface of the rotating shaft 53. The reciprocating screw rod 52 and the rotating shaft 53 are synchronously moved and rotated through the transmission wheel 54 and the synchronous belt 55, so that the C-shaped frame 57 drives the fixed roller 58 to reciprocate, so that the polyester filament is evenly distributed on the winding mechanism.

[0026] Reference Figure 2 - Figure 3 The inner wall of the C-shaped frame 57 is provided with a mounting groove 510, and a pressing assembly 6 is arranged inside the mounting groove 510. The pressing assembly 6 includes a slider 61, which is slidably connected inside the mounting groove 510. The side wall of the slider 61 is rotatably connected with a pressure roller 62. The slider 61 is elastically connected to the inner wall of the mounting groove 510 through a return spring 63. The return spring 63 is used to provide a downward force for the slider 61, so that the pressure roller 62 presses the polyester yarn toward the fixed roller 58 to clamp and fix the polyester yarn, thereby preventing the tail end of the polyester yarn from being loosened when entering the box body 1. The inner wall of the mounting groove 510 is fixedly connected with a guide rod 64, which passes through and is slidably connected to the surface of the slider 61. The guide rod 64 is used to guide the slider 61 so that the slider 61 moves stably inside the mounting groove 510.

[0027] Working principle: When the wire guide device in the polyester winding machine is working, the polyester filament enters from the wire inlet 2, and is first guided by the guide roller 3, so that the direction of the polyester filament is corrected and smoothly enters the box 1. Subsequently, the polyester filament is guided by two sets of guide wheels 4 to further adjust its moving direction to ensure that the polyester filament can accurately enter the wire guide assembly 5.

[0028] In the guide wire assembly 5, the polyester filament contacts the fixed roller 58. Due to the action of the pressing assembly 6, the pressing roller 62 presses the polyester filament tightly against the fixed roller 58 to form a stable clamping state. At this time, the motor drives the winding mechanism to start working, and the winding roller rotates to gradually wind up the polyester filament.

[0029] At the same time, during the winding process, the polyester filament can drive the fixed roller 58 to rotate, and the rotating shaft 53 can be synchronously rotated through the transmission action of the transmission wheel 54 and the synchronous belt 55. The thread on the outer wall of the reciprocating screw rod 52 drives the movable seat 56 to move back and forth horizontally between the inner walls of the fixed frame 51. The movable seat 56 drives the C-shaped frame 57 and the fixed roller 58 to move together, so that the polyester filament is evenly distributed on the winding roller during the winding process.

[0030] When the tail end of the polyester filament enters the box 1, the polyester filament is always clamped between the fixed roller 58 and the pressing roller 62 due to the action of the pressing assembly 6, thereby preventing the tail end from being loosened. At the same time, the guide rod 64 ensures that the slider 61 moves stably inside the mounting groove 510, further ensuring the stable operation of the pressing assembly 6.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
