[0002] A copper strip is a metal component, mainly used for producing electrical components, lamp caps, battery caps, buttons, seals, connectors, mainly used as conductive, heat-conductive and corrosion-resistant materials, such as electrical components, switches, washers, gaskets, electro-vacuum devices, radiators, conductive base materials and various parts such as automobile water tanks, radiator fins, cylinder sheets, etc. The main purpose of annealing pure copper is to soften it. When it needs to be bent, annealing is required to prevent fracture and shrinkage holes. When annealing the copper strip, the copper strip needs to be loaded on a rack structure, and the rack structure is used to support and transfer the copper strip.

The rack is arranged on the base and located inside the heating cover. The rack includes a base and support rods detachably arranged on the base and used for supporting the copper strip. Among them, the base includes: a bottom support plate and a vertical plate. The bottom support plate is a circular plate extending along the circumferential direction and closed; the vertical plate, there are two vertical plates arranged on the bottom support plate at intervals. Both vertical plates extend in the up and down direction and the lower ends are fixedly connected to the vertical plate. The upper part of the vertical plate is provided with a mating groove opening upward; the support rod is in the shape of a square tube, and the support rod is inserted between two groups of mating grooves in a mating manner. A limiting structure for restricting the lateral displacement between the support rod and the mating groove is also arranged at the bottom of the support rod.

[0004] The existing rack structure has the following problems:

[0005] When the existing rack structure continuously transports and rotates the copper strip, there will be an unstable trembling phenomenon. Frequent trembling easily causes the copper strip to skip during transportation and rotation, resulting in the problem of copper strip derailment. Content of the Utility Model

Specific embodiments

[0020] In order to further explain the technical solution of the present utility model, the following will be elaborated in detail through specific embodiments.

[0021] Please refer to Figure 1 and Figure 2 The present utility model provides a material rack structure for copper strip annealing, including a bracket 1. A material - turning roller 2 is arranged inside the bracket 1, a platform 3 is arranged on the bracket 1, and a material - pressing structure 4 is arranged at the top of the bracket 1.

[0022] During the annealing process of the copper strip, the copper strip is loaded on the material - turning roller 2, and then the copper strip is driven to rotate by a driving device, so that the copper strip continuously rotates on the material - turning roller 2 and enters the annealing furnace for annealing treatment.

[0023] Please refer to Figure 2 , Figure 3 and Figure 4 The present utility model provides a material rack structure for copper strip annealing. The material - pressing structure 4 includes a fixed shell 41. The fixed shell 41 is fixed to the top of the bracket 1 by bolts, and the fixed shell 41 is located above the platform 3, so that when the copper strip passes through the platform 3, it will enter the inside of the fixed shell 41. A reinforcing rib 401 is welded to the outside of the fixed shell 41 to improve the stability of the fixed shell 41 and prevent the fixed shell 41 from shaking.

[0024] A threaded sleeve 42 is fixed to the middle end inside the fixed shell 41 by bolts. A screw rod 43 is assembled inside the threaded sleeve 42 and is thread - connected thereto. The upper end of the screw rod 43 protrudes from the top of the fixed shell 41, and a buffer structure 44 is arranged at the bottom of the screw rod 43.

[0025] The buffer structure 44 includes a spring sleeve 441. The lower end of the screw rod 43 is fixed to the spring sleeve 441 by bolts. A spring 442 is assembled inside the spring sleeve 441. A connecting rod 443 is arranged inside the spring sleeve 441. One end of the connecting rod 443 is connected to the spring 442, and the other end of the spring 442 is fixed to the inner wall of the spring sleeve 441. The connecting rod 443 is rotatably connected to a roller - pressing frame 45 arranged inside the fixed shell 41.

[0026] Both the left and right ends of the pressure roller frame 45 are provided with pressure rollers 46 connected by rotation, and the bottom end surfaces of the pressure rollers 46 at the left and right ends are in the same plane, which can press the copper strip in parallel, thereby improving stability.

[0027] At the inner top end of the fixed shell 41, a positioning sleeve 47 is fixed by bolts. Inside the positioning sleeve 47, a vertical rod 48 is arranged, and the vertical rod 48 is connected to the pressure roller frame 45. Vertical rods 48 are fixed at both the left and right ends of the pressure roller frame 45. The structures of the two vertical rods 48 are the same, which is used to limit the pressure roller frame 45 and reduce the unstable shaking of the pressure roller frame 45.

[0028] When the copper strip enters the inside of the fixed shell 41, the staff can rotate the screw rod 43. Since the screw rod 43 is threadedly connected to the threaded sleeve 42, when the screw rod 43 rotates, it will move downward and push the pressure roller frame 45, causing the pressure roller frame 45 to move downward. Continuously rotating the screw rod 43 makes the pressure roller 46 press against the surface of the copper strip. When the copper strip moves, the pressure roller 46 will rotate accordingly. Under the pushing of the pressure roller 46, the vibration of the copper strip can be effectively suppressed, and the stability during the transfer of the copper strip is improved. When the pressure roller 46 presses on the surface of the copper strip, the pressure roller frame 45 will move upward and push the connecting rod 443, and push the compression spring 442, causing the spring 442 to be compressed and generate elastic force. Under the action of the elastic force, the pressure roller can better fit on the surface of the copper strip, with a more effective pushing effect, thereby improving stability. And the activity of the connecting rod 443 allows the pressure roller frame 45 to move slightly upward, preventing the pressure roller 46 from pressing too tightly on the surface of the copper strip and causing serious deformation of the copper strip.

Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
