Therefore, the specific internal structure thereof will not be elaborated in detail, and generally, heating parts are installed inside the heating chamber in the prior art to achieve efficient annealing heating activity for the copper strip.

[0028] Please refer to Figures 2-3, the cleaning device 6 in this embodiment includes a housing 61 fastened to the front side of the roller conveyor 1, clamping plates 62 horizontally installed on the upper and lower sides inside the housing 61 to achieve the stepped clamping and transmission cooperation of the copper strip, a stepped transmission assembly 63 symmetrically arranged at the left ends of the two clamping plates 62 on both sides, and driven by the stepped transmission assemblies 63 arranged on both sides, the two sides can move along opposite square trajectories to achieve the stepped clamping and transmission cooperation of the copper strip. Motors 64 are correspondingly arranged on the left sides of the stepped transmission assemblies 63 on both sides, and a cleaning plate assembly 65 is installed on the upper and lower sides at the front end inside the housing 61 and connected to one of the stepped transmission assemblies 63. In this way, when the stepped clamping and transmission movement of the copper strip is realized, the cleaning plate assembly 65 can be clamped and cleaned.

[0029] Among them, the clamping plates 62 are horizontally arranged symmetrically up and down on the rear side inside the housing 61, and there is a gap between the two clamping plates 62 on both sides to ensure the stability of the intermittent stepped transmission of the copper strip.

[0030] Please refer to Figure 4 , the stepped transmission assembly 63 in this embodiment includes a rotating block 631 rotatably connected to the left side inside the housing 61 and connected to the output end of the motor 64, and the outer side of the rotating block 631 is connected to the clamping plate 62. A rotating rod 632 longitudinally and movably inserted into the rotating block 631 to achieve the circumferential rotation transmission cooperation, a compression spring 633 installed on the outer side of the rotating rod 632 to provide the resilience assistance cooperation, a connecting block 634 connected to the side of the rotating rod 632 away from the rotating block 631, a connecting rod 635 vertically inserted into the connecting block 634 to ensure the stability of the square transmission trajectory, and a guide rod 636 longitudinally inserted into the upper end of the connecting rod 635 and connected to the inner side of the side of the housing 61. In this way, the longitudinal movement guiding cooperation can be realized to make the square trajectory transmission movement of the stepped transmission assembly 63 stable.

[0031] Among them, the connecting rod 635 and the guide rod 636 form a movable L-shaped strip, and the lengths of the connecting rod 635 and the guide rod 636 are the same; the connecting shell 653 is movably sleeved on the outside of the pressing plate 652, and at least seven rows of springs 655 are equally spaced between the pressing plate 652 and the connecting shell 653.

[0032] Please refer to Figures 5-7 , the cleaning plate assembly 65 in this embodiment includes a transmission box 651 built inside the left side of the housing 61 to achieve the clamping and transmission cooperation, pressing plates 652 horizontally installed symmetrically up and down on the outer end of the housing 61, connecting shells 653 correspondingly sleeved on the outside of the two pressing plates 652, cleaning pads 654 bonded to the cleaning surfaces of the two connecting shells 653 for the cleaning cooperation of the upper and lower surfaces of the copper strip, and springs 655 built inside the connecting shells 653 to provide elastic pressing support.

[0033] Among them, the transmission box 651 includes a box body 6511 built inside the left side of the outer shell 61 to achieve the protection and cooperation of internal parts. A transmission bar 6512 is longitudinally inserted into the upper rear end of the box body 6511 and connected to the front end of the connecting block 634 on the upper side. In this way, when the connecting block 634 moves along a square track, the transmission bar 6512 can conveniently push down and drive the first rack 6513 at one lower end. The first rack 6513 is vertically installed on one side inside the box body 6511 and connected to the lower end of one side of the transmission bar 6512. An insertion rod 6514 vertically fixed at the lower end of the first rack 6513 for guiding cooperation, and the lower end of the insertion rod 6514 is vertically and movably inserted into the lower end inside the box body 6511. A return spring 6515 connected to the lower end of the insertion rod 6514 to provide a rebound force. A gear 6516 meshingly connected to the middle of one side of the first rack 6513 and rotatably connected to the middle inside the box body 6511. A second rack 6517 meshingly connected to the other side of the gear 6516, and the second rack 6517 and the first rack 6513 are installed in a vertically opposite front-back state. A limiting rod 6518 vertically inserted into the middle of the second rack 6517 for vertical movement limiting and guiding cooperation.

[0034] Among them, the transmission bar 6512 longitudinally penetrates into the upper rear end inside the box body 6511, and the rear side of the transmission bar 6512 is connected to the upper side step transmission assembly 63, ensuring that the transmission bar 6512 can move with the indirect step transmission to realize the synchronous push-down drive of the first rack 6513 and ensure the stable clamping and docking of the cleaning plate assembly 65 with the upper and lower surfaces of the copper strip.

[0035] Among them, both the first rack 6513 and the second rack 6517 are connected to the left side of the two side pressing plates 652, enabling the two side pressing plates 652 to move synchronously with the first rack 6513 and the second rack 6517.

[0036] The working principle is as follows:

[0037] When annealing the copper strip, the controller 5 provided on the right side of the heating chamber 2 can be used to realize the operation of the roller conveyor 1, the heating parts provided inside the heating chamber 2, and the cooling fan 4. With the operation of the roller conveyor 1, the transmission of the copper strip can be assisted, enabling the copper strip to enter the heating chamber 2 for heating. After heating and maintaining the temperature, the copper strip can be transmitted to the cooling chamber 3. With the cooperation of the cooling fan 4 provided at the upper end of the cooling chamber 3, the heated copper strip can be assisted in cooling. In this way, after the copper strip completes the cooling activity and is exported from the cooling chamber 3, the annealing process of the copper strip can be completed.

[0038] In order to ensure that dust is not easily attached to the outside during the annealing of the copper strip, which may affect the annealing quality of the copper strip, a cleaning device 6 is provided on the front side of the roller conveyor 1. First, the copper strip is placed between the two connecting shells 653 on both sides and the two clamping plates 62 on both sides. At this time, two motors 64 provided on the left side of the outer shell 61 can be driven, so that the output ends of the two motors 64 are connected to drive the transmission of the stepping transmission component 63, that is, the rotating blocks 631 connected to the output ends of the two motors 64 will rotate synchronously in opposite directions. When one rotating block 631 rotates, the rotating rod 632 inserted outside the rotating block 631 will perform a circular rotation activity. Thus, the connecting block 634 connected to one side of the rotating rod 632 will drive the inserted connecting rod 635 inside, so that the connecting rod 635 moves back and forth along the guide rod 636 provided at the upper end. The connecting block 634 can move along a square trajectory under the drive of the circular rotation of the connecting block 634 and the guiding cooperation with the connecting rod 635, while the other connecting block 634 moves along the opposite square trajectory. Thus, the clamping plates 62 provided at the outer ends of the two connecting blocks 634 on the corresponding sides will perform relative clamping, approaching and separating activities along the square trajectory. When the two clamping plates 62 approach each other relatively, the inserted copper strip can be clamped, so that the copper strip realizes intermittent stepping feeding activities, thereby cooperating with the transmission activity of the roller conveyor 1 to extend the time for the copper strip to stay inside the heating chamber 2 and ensure the heating and temperature rising effect of the copper strip;

[0039] Meanwhile, when the upper connecting block 634 drives along a square trajectory, it will synchronously drive the transmission bar 6512 connected to the front side, causing the transmission bar 6512 to move along a square trajectory. In this way, the front end of the transmission bar 6512 will be driven, realizing the downward push of the lower end of the front side against the first rack 6513. As the first rack 6513 moves downward, the insertion rod 6514 inserted at the lower end of the first rack 6513 can achieve vertical movement guiding cooperation, and compress the return spring 6515 provided at the bottom of the insertion rod 6514. By the downward movement of the first rack 6513, it will meshingly drive the gear 6516 connected to one side in the middle, causing the gear 6516 to drive the upward movement of the second rack 6517 meshing on the other side. In this way, the first rack 6513 and the second rack 6517 can achieve opposite vertical movements, and the pressure plates 652 respectively connected to the outer ends of the first rack 6513 and the second rack 6517 will drive the externally connected connection shell 653, causing the connection shell 653 to drive the cleaning pads 654 adhered to the outside to clamp and contact the upper and lower surfaces of the copper strip. Thus, a clamping and cleaning state is formed. At the same time, when the step transmission assembly 63 intermittently steps and transmits the copper strip, the clamping activities of the upper and lower cleaning pads 654 on the upper and lower surfaces of the copper strip are realized in advance. In this way, when the copper strip moves under the intermittent step transmission of the step transmission assembly 63, the upper and lower surfaces of the copper strip can stably contact the clamped cleaning pads 654 on the upper and lower sides, realizing the efficient cleaning cooperation of the dust attached to the outside of the copper strip. Thus, the cleanliness of the outside of the copper strip is ensured, so that when the copper strip undergoes an annealing activity later, it is not easily affected by the attached dust, resulting in the influence of the annealing quality;

[0040] Subsequently, when the step transmission assembly 63 completes the intermittent step transmission activity of the copper strip, the upper connecting block 634 will release the downward pressure effect of the transmission bar 6512 on the first rack 6513. In this way, the return spring 6515 at the lower end of the insertion rod 6514 and in a compressed state will push the first rack 6513 upward to reset, and cooperate with the transmission of the gear 6516 to move the second rack 6517 downward to reset. Thus, the outer pressure plates 652 on both sides will move in the opposite direction to release the clamping effect on the copper strip. Furthermore, through the combined drive of the step transmission assembly 63 and the cleaning plate assembly 65, the intermittent step feeding cooperation of the copper strip can be realized, and the outside of the copper strip can also be assisted in cleaning;

[0041] Secondly, when the pressure plates 652 on both sides drive the externally corresponding connection shells 653 to clamp the upper and lower surfaces of the copper strip with the cleaning pads 654 on both sides, the spring 655 provided between the pressure plates 652 and the connection shells 653 can be compressed to realize the elastic pressing activity, strengthening the clamping and contact cleaning effect of the cleaning pads 654 on both sides.

[0042] The above are only the preferred examples of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
