Abstract
Description
Technical Field
[0001] The utility model relates to the field of copper wire processing, in particular to a linear guide rail wire-receiving structure of an annealing tinning machine. Background Art
[0002] During the production and processing of copper wire, it is necessary to electroplate tin on the surface for protection, which requires the use of an annealing tinning machine. The annealing tinning machine can combine the two processes of annealing and tinning. The annealing process can also eliminate the residual stress generated by the copper wire during the production process of the wire drawing machine, stabilize the size of the copper wire, reduce deformation and crack tendency, refine the grain, adjust the structure, eliminate structural defects, reduce hardness, improve cutting processability, and apply the heat energy in the annealing process to the tinning process, which greatly improves the production efficiency. At the same time, it can also effectively reduce the production energy consumption of the two processing processes, which is more energy-saving and environmentally friendly.
[0003] After the annealing and tinning process of the copper wire is completed, it is necessary to reel in the wire. Most of the existing reeling methods are guided by a guide mechanism to make the copper wire reeled on a reel. As the reel winds the copper wire, the outer diameter of the entire reel continues to increase. When the speed of the reel remains unchanged, the copper wire reeling speed becomes faster, causing the tension amplitude of the copper wire to vary greatly. The copper wire is easily stretched again, causing the diameter of the copper wire to become smaller, resulting in an increase in the error size. Therefore, the utility model provides a linear guide rail reeling structure for an annealing and tinning machine. Utility Model Content

[0027] The distance sensor 9 is a laser distance sensor. The distance between the axis of the wire take-up drum 4 and the laser distance sensor (this is a fixed distance) minus the detected distance is the real-time diameter of the wire take-up drum 4. Through the calculation relationship between the diameter and the linear speed, after knowing the real-time diameter of the wire take-up drum 4, the speed of the wire take-up drum 4 can be kept in a stable range or constant by controlling the rotation speed of the motor 11 in the drive mechanism 3.

By adjusting the position of the movable limit block 21, the spacing between the fixed limit block 20 and the movable limit block 21 is controlled.
[0034] Working principle: In the process of the take-up drum 4 rotating to reel in the copper wire, the copper wire is guided by the left and right movement of the guide limit mechanism, so that the copper wire is evenly reeled on the take-up drum 4, and the overall diameter of the copper wire after the take-up drum 4 is detected by the distance sensor 9, so as to control the rotation speed of the take-up drum 4, so that the take-up speed is kept in a stable range or constant, and the increase in diameter after the copper wire is reeled in is avoided, resulting in an increase in the line speed, thereby causing a large change in the tension amplitude of the copper wire (although the movement of the guide limit mechanism will also cause certain interference to the copper wire and affect its tension, it is still within an acceptable range due to its limited range of movement). Since the distance sensor 9 moves with the vertical plate 6, and the distance sensor 9 is located on the rear side directly below the guide limit mechanism, the detected distance is the distance at the real-time reeling point, which is convenient for better control of the take-up speed, and the guide limit mechanism is driven by the vertical linear slider 26 to move up and down to adjust, so that the guide limit mechanism is at the same height as the highest point (the highest point of the copper wire) after the take-up drum 4 reels the copper wire, so that the take-up drum 4 maintains a good uniform reeling effect.
