A painting gap 604 is formed between the outer side wall of the second annular sponge 603 and the inner side wall of the first annular sponge 602, and the width of the painting gap 604 does not exceed the diameter of the copper wire 11, so that the copper wire 11 can pass through the painting gap easily. 604, the copper wire 11 squeezes the first annular sponge 602 and the second annular sponge 603, and the copper wire 11 passes through the paint gap when it revolves, and rotates around the paint gap 604. While rotating, the copper wire 11 squeezes the first annular sponge 602 and the second annular sponge 603, so that the paint on the inside of the first annular sponge 602 and the second annular sponge 603 can be squeezed to the surface of the copper wire 11, so that the paint is evenly coated on the surface of the copper wire 11, and because the copper wire 11 squeezes the first annular sponge 602 and the second annular sponge 603, the adhesion of the paint can be further improved.

[0044] like Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7As shown, a paint adding mechanism 3 for squeezing paint into the first annular sponge 602 and the second annular sponge 603 is provided on the upper side of the baking box 1. The paint adding mechanism 3 includes a paint box 301 fixedly provided on the upper side of the baking box 1. A first pump body 302 connected to one side of the paint box 301 is fixedly provided on the upper side of the baking box 1. The output end of the first pump body 302 is fixedly connected to a first connecting pipe 303. One end of the first connecting pipe 303 is fixedly connected to an extrusion pipe 304 fixedly provided on one side of the fixing ring 601 and connected to the first annular sponge 602. When in use, the paint inside the paint box 301 is pumped into the first connecting pipe 303 through the operation of the first pump body 302, and then enters the extrusion pipe 304. The paint can be added to the inside of the first annular sponge 602 through the extrusion pipe 304, and the paint inside the first annular sponge 602 can be replenished in time, so that the paint can be evenly coated on the surface of the copper wire 11 later. A flow channel is opened on the inner side of the transmission shaft 8 (not shown in the drawing). The drawing shows a schematic diagram of a baking oven 1, wherein the flow channel is located at the center of the length direction of the transmission shaft 8, and one end of the flow channel is connected to the second annular sponge 603. Specifically, a through hole (not shown in the drawing) is opened in the radial direction of the transmission shaft 8, and the through hole is connected to the flow channel, and the through hole is wrapped by the second annular sponge 603.

The paint flows into the inside of the second annular sponge 603 through the through hole through the flow channel, so that the paint inside the second annular sponge 603 is replenished.

[0045] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Fig. 9 , Fig.13 , Fig.14As shown, a baking mechanism 7 is provided in the middle of the inner side of the baking box 1. The baking mechanism 7 includes an outer baking base 701 fixedly arranged on the inner side of the baking box 1 and sleeved on the outer side of the transmission shaft 8. The outer baking base 701 adopts a hollow circular ring structure. The upper side of the outer baking base 701 is suspended and installed in the baking box 1 by screws. A plurality of external heating tubes 702 are fixedly arranged on the inner side of the external baking base 701. The external heating tubes 702 adopt a circular ring structure. An inner baking base 703 concentric with the external baking base 701 is fixedly sleeved on the outer side of the transmission shaft 8. A plurality of internal heating tubes 704 are fixedly arranged on the outer side of the internal baking base 703. The internal heating tubes 704 adopt a circular ring structure. A baking cavity (not shown in the drawings) is formed between the outer side of the internal baking base 703 and the inner side of the external baking base 701. The width of the baking cavity is slightly larger than the height of the enameled wire barrel 10, so that the copper wire 11 on the enameled wire barrel 10 can be easily wound during the unwinding and winding processes. The copper wire 11 moves freely in the baking cavity. When in use, the copper wire 11 passes through the baking cavity. When the copper wire 11 on the enameled wire barrel 10 on one of the turntables 2 is transferred to the enameled wire barrel 10 on the other turntable 2, since the inner side of the outer baking base 701 is provided with an outer heating tube 702, and the outer side of the inner baking base 703 is provided with an inner heating tube 704, when the copper wire 11 passes through the baking cavity, it will be baked inside and outside at the same time, thereby improving the baking uniformity. Moreover, since the copper wire 11 is spirally wound on the enameled wire barrel 10, the copper wire 11 will revolve in the baking cavity and the distance will change, that is, the distance between the outer heating tube 702 and the inner heating tube 904 of the copper wire 11 will change intermittently, so that the baking of the paint and the copper wire 11 can be carried out continuously and slowly, thereby further improving the baking effect of the copper wire 11 and the paint, making the paint adhere to the copper wire 11 more firmly, and at the same time improving the strength of the copper wire 11.

[0046] It should be noted that, in this enameled wire production process, when in use, the two sliding doors 13 are opened, and then a plurality of enameled wire bobbins 10 with rolled copper wires 11 are installed on the turntable 2 on one side by means of screws. The specific installation steps are as follows: the enameled wire bobbins 10 are placed in the storage slot 5 on one side of the turntable 2, and then one end of the enameled wire bobbins 10 is fixed to one end of the self-rotating rod 401 by means of screws; similarly, the empty enameled wire bobbins 10 are installed on the other turntable 2 in the same way, and then the copper wire 11 wound on the enameled wire bobbins 10 is pulled out, and passes through the paint gap 604 and the baking cavity in turn, so that one end of the copper wire 11 is wound on the empty enameled wire bobbins 10 on the turntable 2 on the other side, and then the door is closed. The two sliding doors 13 are then driven by the servo motor 9 to rotate one of the turntables 2, and the transmission shaft 8 can be used to drive the other turntable 2 to rotate, so that the two turntables 2 rotate synchronously. When the turntable 2 rotates, the gear 402 on the edge of the turntable 2 will mesh with the gear ring 403 on the inner wall of the baking box 1, which can drive the self-rotating rod 401 in the center of the gear 402 to rotate, so that the enameled wire drum 10 at the other end of the self-rotating rod 401 rotates, so that the two turntables 2 can simultaneously drive the enameled wire drum 10 thereon to rotate synchronously, and the rotation directions are consistent, so that the copper wire 10 on the enameled wire drum 10 on one of the turntables 2 can be unwound, and at the same time, the enameled wire drum 10 on the other turntable 2 can be unwound. The drum 10 reels the copper wire 11, so that the copper wire 11 on the enameled wire drum 10 on one of the turntables 2 can be transferred to the enameled wire drum 10 on the other turntable 2, and the copper wire 11 passes through the paint gap when it revolves, and rotates around the paint gap 604, and while rotating, the copper wire 11 squeezes the first annular sponge 602 and the second annular sponge 603, so that the paint inside the first annular sponge 602 and the second annular sponge 603 can be squeezed onto the surface of the copper wire 11, so that the paint is evenly coated on the surface of the copper wire 11, and the copper wire 11 passes through the baking cavity. When the copper wire 11 on the enameled wire drum 10 on one of the turntables 2 is transferred to the other When the enameled wire barrel 10 is on the turntable 2, since an outer heating tube 702 is provided on the inner side of the outer baking base 701 and an inner heating tube 704 is provided on the outer side of the inner baking base 703, when the copper wire 11 passes through the baking cavity, it will be baked simultaneously inside and outside, thereby improving the uniformity of baking. Moreover, since the copper wire 11 will revolve in the baking cavity and the distance will change, the distance between the outer heating tube 702 and the inner heating tube 904 of the copper wire 11 will change intermittently, thereby enabling the baking of the paint and the copper wire 11 to be carried out continuously and slowly, thereby further improving the baking effect of the copper wire 11 and the paint, allowing the paint to adhere to the copper wire 11 more firmly, and at the same time increasing the strength of the copper wire 11.

[0047] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
