DETAILED DESCRIPTION

[0022] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0025] The present invention discloses a preheating device for preheating a wire core to improve adhesion, referring to Figure 1-Figure 12 ,include: A preheating chamber 1 is used to preheat the wire core placed in the preheating chamber 1 to increase the temperature of the wire core; a workbench 2 is located in the heating area of ​​the preheating chamber 1; two rotating units 4 are arranged on the workbench 2 and are used to adjust the position of the wire core, a winding unit 5, and a winding portion 6 connected to the winding unit 5, the winding unit 5 is used to drive the winding portion 6 to rotate, and the winding unit 5 is used to wind the wire core; the winding unit 5 includes a winding assembly arranged on the rotating unit 4, a driving portion 54 connected to the winding assembly, A driving seat 55 connected to the driving portion 54, and a driving shaft 56 arranged on the driving seat 55 and connected to the rotating unit 4; the winding portion 6 is connected to the driving shaft 56; through the coordinated use of the rotating unit 4 and the winding unit 5, not only can the wire core be preheated during the winding process, but the winding assembly can also stop winding after completing part of the winding work for different wire core materials, and then allow the barrel-type preheater or hot air blower or heater in the preheating chamber 1 to continuously heat up a part of the wire core area to complete the preheating of the wire core.

[0026] In a further embodiment, in the prior art, when a cannon-type preheater or a hot air blower or a heater is used, when the winding assembly stops winding, the cannon-type preheater or the hot air blower or the heater can preheat the wire core located on the support unit 3, thereby increasing the temperature of the wire core. However, since the prior art uses hot air to increase the temperature during preheating, the hot air will directly contact the wire core, which will cause the wire core to deform, thereby causing the wire core on the winding portion 6 to rotate in the opposite direction of the winding direction, thereby causing the wire core to unfold, resulting in a disorderly wire core.

[0027] In order to solve the above problems, a driving part 54 is provided in the present device. The driving part 54 is an annular structure and is provided with a plurality of through holes in the circumferential direction. The driving part 54 includes a pawl 543 that penetrates the through hole and is rotatably connected to the inner wall of the through hole, an abutting tooth 544 arranged on the pawl 543, and a spring piece 545 arranged on the outer wall of the driving part 54; wherein the free end of the abutting tooth 544 points to the driving seat 55, and the driving seat 55 is a columnar structure, and a plurality of placement grooves are provided on its curved surface, and the free ends of the abutting teeth 544 are all located in the placement grooves; there is a predetermined angle between the free end of the abutting tooth 544 and the free end of the pawl 543, and one end of the spring piece 545 abuts against the abutting tooth 544 and the distance therefrom is 1 / 40mm. There is a predetermined distance between the tooth 544 and the pawl 543; the winding assembly includes a winding motor 51 fixedly mounted on the rotating unit 4, a driving gear 52 connected to the output end of the winding motor 51, and a coaxial gear 53 meshing with the driving gear 52; the driving part 54 includes a movable seat 541 arranged on the rotating unit 4, and a driven gear 542 sleeved on the movable seat 541; wherein the coaxial gear 53 includes a small gear meshing with the driving gear 52, a large gear meshing with the driven gear 542, and a coaxial shaft for connecting the small gear and the large gear; the through hole is opened on the movable seat 541, and when the wire core is normally wound, the winding assembly works When the drive unit 54 is in motion, the moving winding assembly drives the driving part 54 to rotate. At this time, the winding motor 51 starts to work. The moving winding motor 51 can drive the driving gear 52 to rotate. Then the moving driving gear 52 can drive the coaxial gear 53 to rotate. Then the moving coaxial gear 53 drives the driving part 54 to rotate through the driven gear 542 in the driving part 54. Then the working driving part 54 can drive the ratchet 543 to move, so that the abutting tooth 544 moves in the placement groove. At this time, the driving part 54 rotates clockwise. When the driving part 54 rotates counterclockwise, the free end of the abutting tooth 544 abuts against one side of the placement groove, thereby causing the ratchet 543 to move toward the driving seat 55, causing the spring piece 545 to deform. The amount increases, and the pawl 543 is in a clamped state. At this time, the drive seat 55 can rotate counterclockwise under the drive of the winding component; when the cable is subjected to external force to cause the drive seat 55 to rotate in the opposite direction, that is, after completing part of the winding work, the winding component stops working at this time, and the hot air generated will blow the wire core, thereby causing the drive seat 55 to rotate in the opposite direction. The reverse moving drive seat 55 will still make the pawl 543 move toward the drive seat 55, so that the pawl 543 is in a clamped state. At this time, the pawl 543 can hinder the rotation of the drive seat 55, and the drive seat 55 stops reversing, avoiding the re-unfolding of the wound cable and avoiding the clutter of the cable. At the same time, it can also ensure the smooth preheating of the wire core. In this process, the counterclockwise direction is the winding direction of the wire core.

[0028] In a further embodiment, in the prior art, since the wire core itself has a certain weight, in order to ensure the preheating efficiency of the wire core in the preheating chamber 1, the wire core is placed in a serpentine manner in the preheating chamber 1, thereby increasing the placement length of the wire core in a unit space. However, this method will cause the wire core to deform under the influence of its own weight, thereby causing the winding part 6 to rotate.

When preheating, one end of the wire core passes through the gap between the limiting protrusion 363 in one of the supporting parts and the limiting wheel 362, and then bypasses the next supporting part in turn, so that the wire core presents an S shape between the supporting parts, thereby completing the support work of the wire core while increasing the length of the wire core, thereby ensuring the efficiency of preheating.

[0031] The rotating unit 4 includes a rotating motor 41 and a transmission shaft 42 arranged on the workbench 2, a driving wheel 43 respectively arranged at the output end of the rotating motor 41 and one end of the transmission shaft 42, a transmission belt 44 for connecting the two driving wheels 43, a rotating seat 48 arranged at the other end of the transmission shaft 42, and a transmission frame 45 arranged on the rotating seat 48; when the rotating motor 41 starts to rotate, the moving rotating motor 41 can drive the rotating seat 48 to rotate through the arranged driving wheel 43 and the transmission belt 44, and the moving rotating seat 48 can drive the transmission frame 45 to start working, and then the position of the clamping seat 47 can be adjusted, thereby adjusting the angle between the axis of the winding part 6 located on the clamping seat 47 and the ground, adjusting the tightness of the wire core, and preventing the wire core from being too loose.
