Copper strip is characterized by uniform thickness and smooth surface. It can be cold-rolled or hot-rolled according to different needs.

[0003] In order to improve the hardness of the copper strip, a heat treatment device is needed to heat the copper. For example, Chinese patent CN216073959U discloses a copper strip heat treatment device, which relates to metal heat treatment equipment technology and aims to solve the problem that the copper strip is generally in a rolled state, so that the inner circle of the copper strip may not be able to receive the temperature of the oven for proper heat treatment. The key points of its technical solution are: an oven with an opening on the front, a track located below the oven, a support platform slidably connected to the track, and a baffle fixedly connected to the support platform and closed with the opening, the baffle is rotatably connected with a fitting and a receiving roller horizontally arranged above the support platform, a copper strip fixing part is arranged on the outer peripheral wall of the receiving roller, the fitting and the receiving roller rotate in the same direction, and the two rotate forward and reverse alternately. The utility model can make the inner and outer copper strips both be fully heated, so that people can obtain copper strips of higher quality.

[0004] However, there are still problems. When heating the copper strip, the device utilizes the waste heat of high-temperature flue gas. When in use, the hot air flow inside the oven is not fluid enough and the temperature rises slowly, resulting in poor temperature uniformity when the object is heated inside, thereby causing the heat treatment effect to deteriorate. Therefore, a copper strip heat treatment device is proposed to solve the above problems. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a copper strip heat treatment device having the advantages of good heating effect, etc., and solves the problem that the temperature of the prior device rises slowly and affects the heat treatment effect.

[0007] The driving mechanism includes a servo motor fixed to the bottom wall of the box body, the output shaft of the servo motor is fixed with a driving gear, two guide rods are fixed between the left and right side walls of the inner cavity of the box body and are distributed front and back, the outer surfaces of the two guide rods are slidably connected with a tooth plate meshing with the driving gear, and two fans are fixed on the top of the tooth plate.

[0008] Furthermore, a mounting bracket is fixed on the outer surface of the servo motor, and the servo motor is fixed to the inner bottom wall of the box body through the mounting bracket.

[0009] Furthermore, sensing probes are fixed on both the left and right sides of the tooth plate, and movable holes adapted to the two guide rods are opened in the tooth plate.

[0020] 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.

[0021] See also Figure 1-2 The front side of the air duct 3 is provided with a plurality of exhaust ports, and the exhaust ports 3 can be used to evenly distribute the hot air in the inner cavity of the box body 1, thereby ensuring that the internal temperature of the box body 1 is consistent with that of the air duct 3, and the exhaust port 3 can be used to evenly distribute the hot air in the inner cavity of the box body 1, thereby ensuring that the internal temperature of the box body 1 is consistent with that of the air duct 3, thereby preventing the heat treatment effect of the copper strip from being affected by excessive temperature difference.

[0022] It should be noted that a driving mechanism 4 is fixed to the inner bottom wall of the box 1, and the driving mechanism 4 can improve the air flow inside the box 1. Two placement plates 5 for placing copper strips are movably connected between the left and right side walls of the inner cavity of the box 1. A number of air holes are provided on the two placement plates 5. The air holes can make the copper strip heated more evenly, avoiding slow heating of the bottom of the copper strip during heat treatment, resulting in uneven heating of the copper strip as a whole, thereby affecting the effect of heat treatment and avoiding manual turning over of the copper strip. Movable grooves compatible with the left and right sides of the placement plates 5 are provided on the left and right sides of the box 1. The movable grooves can more conveniently pull out and insert the placement plates 5 into the box 1, avoiding difficulty in pulling due to excessive weight of the copper strip. Handles are fixed on the front of the two placement plates 5.

[0023] In this embodiment, after the hot air is transferred to the box 1 by the hot air blower 2, the driving mechanism 4 is used to accelerate the circulation of the hot air inside the box 1, so that the temperature inside the box 1 rises rapidly, achieving the purpose of good heating effect, and the copper strip is heated more evenly.

[0024] See also Figure 3 In order to achieve a good heating effect, the driving mechanism 4 in this embodiment includes a servo motor 401 fixed to the inner bottom wall of the box body 1, a mounting frame is fixed to the outer surface of the servo motor 401, the servo motor 401 is fixed to the inner bottom wall of the box body 1 through the mounting frame, and the output shaft of the servo motor 401 is fixed with a driving gear 402. Two guide rods 403 are fixed between the left and right side walls of the inner cavity of the box body 1 and are distributed front and back. The guide rods 403 can limit the displacement direction of the tooth plate 404, so that the tooth plate 404 can only be translated left and right, thereby making the tooth plate 40 4 is more stable when moving, and the moving path will not deviate when meshing with the driving gear 402. The outer surfaces of the two guide rods 403 are slidably connected with the toothed plates 404 meshing with the driving gear 402. Induction probes are fixed on the left and right sides of the toothed plates 404. The induction probes can prevent the toothed plates 404 from colliding with the inner cavity of the box body 1 during movement, thereby avoiding affecting the service life of the entire device and causing serious wear and tear that makes it unusable. The toothed plates 404 are provided with movable holes that are compatible with the two guide rods 403, and two fans 405 are fixed on the top of the toothed plates 404.

[0025] In this embodiment, the driving gear 402 is engaged with the tooth plate 404, driving the tooth plate 404 to translate left and right while driving the fan 405 to move back and forth, so that the hot air inside the box 1 can circulate quickly, thereby causing the temperature inside the box 1 to rise quickly, achieving the purpose of good heating effect.

[0026] The electrical components appearing in the text are all electrically connected to the controller and the power supply. The control method of the utility model is controlled by the controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power supply is also common knowledge in this field. The utility model is mainly used to protect mechanical devices, so the utility model will no longer explain the control method and circuit connection in detail.

[0027] The working principle of the above embodiment is:

[0028] After the copper strip is placed on the placement plate 5, the sealing door 6 is closed, and then the hot air blower 2 is started. After the hot air blower 2 is started, the hot air is transported to the air duct 3. When the hot air is discharged from the exhaust port to the inside of the box 1 through the air duct 3, the servo motor 401 and the two fans 405 are started. The output shaft of the servo motor 401 rotates while driving the driving gear 402 to engage with the tooth plate 404. Since the tooth plate 404 is restricted by the two guide rods 403, the tooth plate 404 can only be driven to move left and right. When the tooth plate 404 drives the fan When the fan 405 moves to the far left, the left sensing probe contacts the left wall of the inner cavity of the box body 1. At this time, the servo motor 401 will rotate in the right direction and drive the gear plate 404 to move to the right. When the right sensing probe contacts the right wall of the inner cavity of the box body 1, the servo motor 401 will reverse again, and operate reciprocatingly to make the fan 405 move left and right to blow the hot air output by the air duct 3, accelerate the flow of the internal hot air flow, quickly heat up the box body 1, and evenly heat the copper strip, thereby achieving the purpose of good heating effect.
