Description

Technical Field

[0001] This application relates to the field of copper wire tin coating equipment, and more particularly, to an automatic tin adding device for copper wire tin coating. Background Art

[0002] Tin coatings are widely used in food processing equipment and containers, as well as shipping equipment, pump components, bearings, valves, automotive pistons, tinned copper wires and CP wires, electronic components, and printed circuit boards.

[0003] To coat copper wire, tin bars need to be melted first. After a single tin bar is melted, a new tin bar needs to be added to the coating machine for replenishment. The common way to replenish tin bars is for workers to manually put the tin bars into the heating box beside it. This way hands over simple repetitive operations to workers, and workers are prone to fatigue after long-term operation, resulting in a decrease in production efficiency. Summary of the Invention

[0029] Refer to Figures 1-5 ,

[0030] An automatic tin - adding device for copper wire with tin coating, comprising: a heating box 1, a rotating cylinder 2, a support plate 3 and a power device 4. A blanking hole is formed at the upper end of the heating box 1. A plurality of accommodating holes 5 are formed in the rotating cylinder 2, and the accommodating holes 5 are used to accommodate tin bars. The plurality of accommodating holes 5 are circumferentially arrayed around the axis of the rotating cylinder 2, and the accommodating holes 5 penetrate through the upper and lower ends of the rotating cylinder 2. The support plate 3 is fixed to the upper end of the heating box 1 by bolts. The upper end of the support plate 3 is in contact with the lower end of the rotating cylinder 2, and the support plate 3 shields the accommodating holes 5 except those located above the blanking hole. The power device 4 causes the rotating cylinder 2 to rotate around its own axis. The tin bars accommodated in the rotating cylinder 2 are supported by the support plate 3. When any one of the accommodating holes 5 rotates above the blanking hole, the tin bar will fall from the accommodating hole 5 into the heating box 1 for heating.

[0031] Specifically, the heating box 1 comprises: a box body 6 and a heater 7. A blanking hole is formed at the upper end of the box body 6. For the heater 7, an existing electric heating machine is selected. The heater 7 is installed on the upper end of the box body 6 by bolts. The heater 7 forms a heating cavity 8. The accommodating hole 5, the heating cavity 8 and the blanking hole are communicated from top to bottom. The tin bar falling from the accommodating hole 5 is first heated and melted in the heating cavity 8, and then falls into the box body 6 from the blanking hole.

[0032] Specifically, the inner wall size of the heating cavity 8 gradually decreases from top to bottom, that is, the upper end of the heating cavity 8 can accommodate the tin bar to enter. Once the tin bar enters the heating cavity 8, it is stuck until the lower part or all of the lower end of the tin bar is melted by the heating cavity 8. The size of the lower end of the tin bar decreases or the tin bar becomes shorter. Under the action of gravity, the tin bar continues to fall and abuts against the inner wall of the heating cavity 8 again for heating.

[0033] Specifically, it further comprises: a diversion pipe 9. The diversion pipe 9 is placed in the box body 6. The upper end of the diversion pipe 9 is fixedly connected to the blanking hole by welding. The lower end of the diversion pipe 9 is 10 - 15 cm away from the bottom surface inside the box body 6, specifically 10 cm. The molten tin entering the box body 6 from the blanking hole flows along the diversion pipe 9 and falls on the lower end inside the box body 6. The diversion pipe 9 plays a role in decelerating and guiding the molten tin, preventing the molten tin from falling too fast and splashing and hurting people when hitting the box body 6.

[0034] Specifically, it further comprises: a pressing block 10. A coating plane 11 is formed on the bottom surface inside the box body 6. The coating plane 11 is used to support the molten tin falling from the blanking hole. The copper wire can be coated with tin when moving on the coating plane 11. The pressing block 10 is placed on the coating plane 11, and the pressing block 10 partially overlaps with the coating plane 11 to press the copper wire on the coating plane 11, preventing the copper wire from jumping and reducing the uniformity of the tin layer wrapping.

[0035] Specifically, it further includes: an exhaust pipe 12. The lower end of the exhaust pipe 12 is connected to and communicated with the upper end of the box body 6 by bolts. The lower end of the exhaust pipe 12 points to the pressing block 10. Harmful gases generated during the reaction of the copper wire, molten tin, and the flux carried by the copper wire are discharged out of the box body 6 by the exhaust pipe 12, preventing the harmful gases from accumulating in the box body 6 and causing poisoning when workers open the box body 6 for maintenance.

[0036] Specifically, the power device 4 includes: a motor 13, a small pulley 14, a belt 15, and a large pulley 16. The motor 13 is installed on the upper end of the box body 6 by bolts. The output end of the motor 13 is connected to the small pulley 14 by a flat key. The large pulley 16 is connected to the rotating cylinder 2 by a flat key. The lower end of the rotating cylinder 2 is rotatably connected to the box body 6 through a bearing. The belt 15 is sleeved on the small pulley 14 and the large pulley 16 to form a speed-reducing transmission connection. When the motor 13 starts, it drives the small pulley 14 to rotate. The small pulley 14 drives the belt 15 to rotate. The belt 15 drives the large pulley 16 to rotate. The large pulley 16 drives the rotation to rotate the receiving hole 5 above the blanking hole.

[0037] The above description is only some preferred embodiments of the present disclosure and an explanation of the applied technical principles. Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by the specific combination of the above technical features, and should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the above inventive concept.
