It also includes: a support plate installed at one end of the outer wall of the top of the workbench, a fixed pipe installed on the outer wall of the top of the support plate, and a sleeve installed inside the fixed pipe. The inner wall of the sleeve is equipped with equally spaced pressure film components, and the outer wall of the sleeve is provided with equally spaced air inlet holes. A hot air component is installed on one outer wall of the fixed pipe.

[0005] The hot air component includes an air hood, an air inlet hopper connected to one end of the air hood, an electric fan installed on the inner wall of the air inlet hopper, and an electric heating wire installed on the inner wall of the air inlet hopper.

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1-6, A stranding device for producing copper-based silver-plated wire provided by the present utility model includes: a stranding machine body 1, a workbench 2 installed on the stranding machine body 1, and a film winding machine 3 installed on the workbench 2. It further includes: a support plate 4 installed at one end of the outer wall of the top of the workbench 2, a fixed pipe 5 installed on the outer wall of the top of the support plate 4, a sleeve 7 installed inside the fixed pipe 5, pressure film assemblies 8 installed at equidistant intervals inside the sleeve 7, and air inlet holes 9 distributed at equidistant intervals on the outer wall of the sleeve 7. A hot air assembly 6 is installed on one side outer wall of the fixed pipe 5.

[0021] It should be noted here that: the wire reel of the copper-based silver-plated wire is installed on the stranding machine body 1. After the stranding machine body 1 twists multiple strands of copper-based silver-plated wire into one strand, the film winding machine 3 winds and coats the surface of the wire. The wire after winding and coating passes through the sleeve 7. Hot air is introduced into the fixed pipe 5 through the hot air assembly 6. The hot air passes through the air inlet holes 9 on the sleeve 7 and blows on the film, playing a role in softening the film. At the same time, as the wire passes through the sleeve 7, its surface is squeezed by multiple pressure film assemblies 8 with small volumes. The softened film is squeezed into the grooves on the wire surface by the pressure die assemblies 8, so that the film can fit well on the surface of the wire and the film adheres tightly and is not easy to fall off.

[0022] In a preferred embodiment, the hot air assembly 6 includes an air hood 601, an air inlet hopper 602 connected to one end of the air hood 601, an electric fan 603 installed on the inner wall of the air inlet hopper 602, and an electric heating wire 604 installed on the inner wall of the air inlet hopper 602.

[0023] It should be noted here that: after the electric fan 603 operates to blow air and is heated by the electric heating wire 604, hot air is formed and blown into the fixed pipe 5.

[0024] In a preferred embodiment, the pressure film assembly 8 includes an elastic rod 801, a mounting frame 802 fixed to the bottom of the elastic rod 801, rotating rods 803 inserted on both outer walls of the mounting frame 802 through bearings, a pressure wheel 804 fixed to the opposite outer walls of the two rotating rods 803, and pressure blocks 805 fixed on the outer wall of the pressure wheel 804 and distributed at equidistant intervals.

[0025] It should be noted here that: the elastic rod 801 can press the pressure wheel 804 against the wire surface. As the wire moves, it drives the pressure wheel 804 to roll, and the pressure blocks 805 on the surface of the pressure wheel 804 press the film on the wire surface into the grooves on the wire surface.

[0026] In a preferred embodiment, the elastic rod 801 includes a mounting pipe 801-1, a movable rod 801-2 slidably connected to the inner wall of the mounting pipe 801-1, and a spring 801-3 provided inside the mounting pipe 801-1.

[0027] It should be noted here that: The wire passes through the inside of the sleeve 7, pushing the pressing wheel 804. The pressing wheel 804 drives the mounting bracket 802 to push the movable rod 801-2 into the mounting tube 801-1, squeezing the spring 801-3. Through the reaction force of the spring 801-3, the pressing wheel 804 is pressed against the surface of the wire.

[0028] In a preferred embodiment, a connection port 10 is formed on the outer wall of one side of the fixed tube 5, and the air hood 601 is connected to the inner wall of the connection port 10.

[0029] It should be noted here that: The hot air can enter the fixed tube 5 through the air hood 601 and the connection port 10.

[0030] In a preferred embodiment, the mounting bracket 802 is of an inverted "U" shape structure.

[0031] It should be noted here that: It is convenient to install the pressing wheel 804.

[0032] Working principle: Install the wire reel of the copper-based silver-plated wire on the stranding machine body 1. After the stranding machine body 1 twists multiple strands of copper-based silver-plated wire into one strand, use the film winding machine 3 to wind and coat the surface of the wire. The wire after winding and coating passes through the sleeve 7. After the electric fan 603 runs and blows air, which is heated by the electric heating wire 604, hot air is formed and blown into the fixed tube 5. The hot air passes through the air inlet holes 9 on the sleeve 7 and blows on the film, playing a role in softening the film. At the same time, when the wire passes through the inside of the sleeve 7, it will push the pressing wheel 804. The pressing wheel 804 drives the mounting bracket 802 to push the movable rod 801-2 into the mounting tube 801-1, squeezing the spring 801-3. Through the reaction force of the spring 801-3, the pressing wheel 804 is pressed against the surface of the wire. During the movement of the wire, it drives the pressing wheel 804 to roll. Use the pressing block 805 on the surface of the pressing wheel 804 to press the film on the surface of the wire into the grooves on the surface of the wire, so that the film can fit well on the surface of the wire, and the film is tightly attached and not easy to fall off.
