Description

Technical Field

[0028] The technical solution of this utility model will be described below with reference to the accompanying drawings and embodiments.

[0029] like Figures 1 to 7As shown, the winding machine of this utility model includes a frame 1, on which are provided an asbestos thread roll mounting position 2, a lead wire roll mounting position 4, a winding device, a finished product receiving device 8, and a control device 14. An asbestos thread roll is placed on the asbestos thread roll mounting position 2, and the free end of the asbestos thread roll passes through the lead wire roll mounting position 4 and is fixed to the receiving device 8, which is driven to rotate by a stepper motor 12. A lead wire roll is placed on the lead wire roll mounting position 4, and the free end of the lead wire roll passes through the winding device and is fixed to the asbestos thread located in front of the receiving device 8, which is driven to rotate by a servo motor 13. When the servo motor 13 drives the winding device to rotate, it releases the free end of the lead wire roll and winds the lead wire onto the asbestos thread. When the stepper motor 12 drives the receiving device 8 to rotate, it pulls the free end of the asbestos thread roll or the finished product after winding for winding. With this setup, before operation, the asbestos thread roll and lead wire roll are respectively mounted on the asbestos thread roll mounting position 2 and the lead wire roll mounting position 4. Then, the free end of the asbestos thread roll is passed through the lead wire roll mounting position 4 and fixed to the take-up device 8. At the same time, the free end of the lead wire roll is passed through the winding device and fixed to the asbestos thread located in front of the take-up device 8. During operation, the stepper motor 12 and the servo motor 13 work simultaneously. When the servo motor 13 drives the winding device to rotate, it releases the free end of the lead wire roll and winds the lead wire onto the asbestos thread. When the stepper motor 12 drives the take-up device 8 to rotate, it pulls the free end of the asbestos thread roll or the finished product after winding for winding. This setup has high efficiency, saves labor, and can evenly wind the lead wire onto the asbestos thread, improving the yield rate.

[0030] Specifically, the stepper motor 12 drives the take-up device 8 to rotate, thereby pulling the free end of the asbestos thread roll for winding. During the winding process, the servo motor 13 drives the winding device to rotate, thereby releasing the free end of the asbestos thread roll and evenly winding the lead wire around the asbestos thread. Finally, the finished roll after winding is placed on the take-up device 8.

[0031] In practical applications, in the initial state, the take-up device 8 winds up the unwound asbestos thread. After pulling it to a certain position, it winds up the finished product.

[0032] Furthermore, the asbestos thread roll mounting position 2 is provided with an asbestos thread roll mounting shaft 21 for placing the asbestos thread roll; the lead wire roll mounting position 4 includes a first mounting base 41, a second mounting base 42, and a lead wire roll mounting shaft 43. The first mounting base 41 and the second mounting base 42 are installed on the frame 1 at intervals. The lead wire roll mounting shaft 43 is installed on the first mounting base 41 and the second mounting base 42, and a lead wire roll is placed on the lead wire roll mounting shaft 43; the lead wire roll mounting shaft 43 is provided with an asbestos thread through hole 431 to facilitate the passage of asbestos thread, and a conical guide wheel 432 is fixed at one end of the lead wire roll mounting shaft 43 near the take-up device 8; the free end of the asbestos thread roll passes through the asbestos thread through hole 431 and is fixed on the take-up device 8; the free end of the lead wire roll passes through the winding device and is wound around the asbestos thread located at the outlet of the asbestos thread through hole 431; a protective cover 46 is movably provided on the outside of the lead wire roll mounting position 4, and the protective cover 46 is hinged to the frame 1.

[0033] In practical applications, the first mounting base 41 can be detachably mounted on the frame 1, which facilitates the loading, unloading and replacement of the lead wire roll. The lead wire roll mounting shaft 43 is fixed after assembly and will not rotate. When the winding device rotates, it rotates relative to the lead wire roll mounting shaft 43, so as to release the free end of the asbestos wire roll and evenly wind the lead wire onto the asbestos wire.

[0034] Furthermore, the lead wire roll mounting shaft 43 is equipped with two spaced-apart limiting wheels 44, and the lead wire roll is placed between the two limiting wheels 44. Two adjusting wheels 45 are respectively provided on the outer sides of the two limiting wheels 44, and the two adjusting wheels 45 are used to adjust the distance between the two limiting wheels 44. This arrangement uses the two limiting wheels 44 to limit and fix the asbestos wire roll, preventing it from rotating, and the two adjusting wheels 45 to adjust the distance between the two limiting wheels 44, allowing for the assembly of asbestos wire rolls of different lengths, making it more convenient to use.

[0035] Furthermore, the winding device is rotatably mounted on the lead wire roll mounting shaft 43, and the winding device is located between the conical guide wheel 432 and the lead wire roll; the winding device includes a fly fork 91, a rotating fly wheel 92, a lead wire guide tube 93, and a second transmission gear 94; the second transmission gear 94 is rotatably mounted on the second mounting base 42, and the second transmission gear 94 is driven to rotate by the servo motor 13; the first end of the rotating fly wheel 92 is fixedly connected to the fly fork 91, and the second end of the rotating fly wheel 92 is fixed inside the second transmission gear 94; the lead wire guide tube 93 is fixed on the rotating fly wheel 92, the fly fork 91 is provided with a first lead wire through hole 911 to facilitate the passage of lead wire, and the lead wire guide tube 93 is provided with a second lead wire through hole 931 to facilitate the passage of lead wire; the free end of the lead wire roll passes through the lead wire through hole 95 of the fly fork 91 and the lead wire guide tube 93 and is then wound onto the asbestos thread. With this configuration, when the servo motor 13 drives the second transmission gear 94 to rotate, the second transmission gear 94 drives the rotating flywheel 92 to rotate. When the rotating flywheel 92 rotates, it drives the flying fork 91 and the lead wire guide tube 93 to rotate simultaneously. When the flying fork 91 rotates, it makes a circular motion relative to the lead wire roll, thereby releasing the free end of the lead wire roll. When the lead wire guide tube 93 rotates, it winds the lead wire onto the asbestos line that is being pulled.

[0036] In practical applications, the lead wire guide tube 93 is arranged parallel to the lead wire roll mounting shaft 43, and the lead wire through hole 95 outlet of the lead wire guide tube 93 is located beside the conical guide wheel 432; the conical guide wheel 432 is provided with an inclined surface to prevent the lead wire from interfering with the conical guide wheel 432 when rotating, causing the lead wire to break.

[0037] Furthermore, the output end of the servo motor 13 is fixed with a second drive gear 131, and a second transmission toothed belt is wound around the second drive gear 131 and the second transmission gear 94. The servo motor 13 is controlled to start and stop and its speed is set by the control device 14. With this configuration, when the servo motor 13 is working, it drives the second drive gear 131 to drive the second transmission gear 94 and the second transmission toothed belt to move, thereby driving the winding device to rotate and realize the feeding of the lead wire roll and winding it onto the asbestos thread.

[0038] Furthermore, an asbestos wire guide plate 3 and a pressing wheel device are provided between the lead wire roll mounting position 4 and the asbestos wire roll mounting position 2, and a pressing wheel device and a guide roller 6 are provided between the lead wire roll mounting position 4 and the receiving device 8; the asbestos wire guide plate 3 is provided with an asbestos wire guide hole 31 to facilitate the passage of asbestos wire; the guide roller 6 is provided with a guide groove 61 to facilitate the guiding of finished product.

[0039] Furthermore, the pressing wheel device 5 includes a fixed frame 51, a movable frame 52, a fixed rotating wheel 53, an adjusting rotating wheel 54, and an adjusting device; the fixed frame 51 is fixed to the machine frame 1, the movable frame 52 is adjustable and located above the fixed frame 51, the fixed rotating wheel 53 is positioned and installed on the fixed frame 51, the adjusting rotating wheel 54 is positioned and installed on the movable frame 52, the adjusting rotating wheel 54 is correspondingly arranged with the fixed rotating wheel 53, and is formed with a gap to facilitate the passage of lead wire; the adjusting device is used to adjust the displacement of the movable frame 52 relative to the fixed frame 51, so as to adjust the size of the gap between the adjusting rotating wheel 54 and the fixed rotating wheel 53.

[0040] In practical applications, there are multiple sets of clamping roller devices 5. These multiple sets of clamping roller devices 5 facilitate the pulling of the wire and guide it during the pulling process, preventing the wire from dislodging. Specifically, the clamping roller device between the lead wire roll mounting position 4 and the asbestos wire roll mounting position 2 is used to guide and assist in pulling the asbestos wire; and the clamping roller device between the lead wire roll mounting position 4 and the take-up device 8 is used to guide and assist in pulling the finished product.

[0041] Furthermore, the adjustment device includes an adjusting screw 55, a limiting block 56, and a guide rod 57. Both ends of the guide rod 57 are fixed to the fixed frame 51 and the limiting block 56, respectively. The movable frame 52 is movably positioned on the guide rod 57. The adjusting screw 55 passes through the limiting block 56 and abuts against the movable frame 52. The adjusting screw 55 and the limiting block 56 are threaded together. A spring is fitted onto the guide rod 57 between the movable frame 52 and the fixed frame 51. With this configuration, the position of the movable frame 52 on the guide rod 57 can be adjusted by rotating the adjusting screw 55. Specifically, when the adjusting screw 55 is rotated, the movable frame 52 is pushed downwards; when the adjusting screw 55 is rotated in the opposite direction, the movable frame 52 moves upwards under the spring force.

[0042] Furthermore, a tensioning wheel device 7 is provided between the guide roller 6 and the take-up device 8; the tensioning wheel device 7 includes a first tensioning wheel 71, a second tensioning wheel 72, a mounting plate 73, and a fixed base 74; the fixed base 74 is fixed to the frame 1, and the first tensioning wheel 71 and the second tensioning wheel 72 are mounted on the mounting plate 73 in adjustable positions, and the mounting plate 73 is mounted on the fixed base 74; the guide roller 6, the first tensioning wheel 71, the second tensioning wheel 72, and the take-up device 8 are arranged in a corresponding sequence. With this arrangement, the tension of the wire during the pulling process can be adjusted by adjusting the positions of the first tensioning wheel 71 and the second tensioning wheel 72.

[0043] Furthermore, the receiving device 8 includes a mounting block 81, a first transmission gear 82, and a receiving wheel 83. The mounting block 81 is fixed to the frame 1.
