Background
Tinned copper wire is copper wire with a thin layer of metallic tin plated on the surface of the copper wire. The tinned copper wire is softer in material and good in conductivity, and compared with a bare copper wire, the tinned copper wire is higher in corrosion resistance and oxidation resistance, and the service life of a weak current cable can be greatly prolonged; furthermore, the exterior of the copper wire needs to be plated with tin because the copper wire is oxidized by air to form a film, i.e., verdigris, when the copper wire is exposed to air for a long time, and the electrical conductivity of the verdigris is poor, which increases the resistance.
When the existing cable is tinned, the process flow is generally as follows: the method comprises the steps of firstly discharging a copper wire from a coil, then putting the copper wire into a hydrochloric acid pool for acid washing to remove stains on the surface of the copper wire, then putting the copper wire into a clean water pool for washing away hydrochloric acid water, and then putting the copper wire into a soldering flux pool. After passing through the soldering flux pool, the copper wire enters a tinning bath, penetrates out of the tinning bath, and is packed by taking up an integrated coil; however, since the copper wire is pulled, the angle of the discharged material is deviated, once the angle is deviated, the thickness of the tin layer on the surface of the copper wire is uneven during discharging, a cable "male-female surface" is formed, the male-female surface causes that the copper wire is likely to be partially exposed to the outside, and the copper wire is oxidized to generate verdigris for a long time.

Because traditional tinning equipment often makes the tin coating of copper line inhomogeneous when the copper line tin-plating ejection of compact, the copper line after the ejection of compact forms "yin yang face"; the most important thing for preventing the generation of the 'negative and positive surfaces' during the discharging of the copper wires is to keep the copper wires and the discharging holes 44 in the vertical (90 DEG) discharging direction; the embodiment adopts the following technical scheme, specifically, two ends of the positioning plate 22 are slidably arranged on a notch of the liquid storage tank 1, sliders are arranged at bottoms of two ends of the positioning plate 22, a chute is formed in the notch of the liquid storage tank 1, the sliders are placed in the chute, so that the wire pressing mechanism 2 can slide transversely, in order to relatively position a position of the wire pressing mechanism 2, regulators are respectively arranged on the notches at two ends of the positioning plate 22, each regulator comprises a fixed seat 11 and a regulating column 12 arranged on the fixed seat 11, the regulating column 12 is connected to the fixed seat 11 through a thread, one end of the regulating column 12 is abutted against an end of the positioning plate 22, and the movement of the wire pressing mechanism 2 is relatively limited by rotating the regulating columns 12 at two sides, so that the position of the wire pressing mechanism 2 is fixed; when the position of line ball mechanism 2 needs to be adjusted, only need finely tune line ball mechanism 2's position through rotating the regulator for whole line ball mechanism 2 can carry out lateral shifting, go up to discharge opening 44 on the copper line of pressing in line ball mouth 211 respectively in order to adjust and be perpendicular.
In this embodiment, both sides of play work or material rest 4 are a fixedly connected with dispatch board 45 respectively, the notch both ends of reservoir 1 are equipped with the stand respectively, dispatch board 45 articulates on the stand, and relative stand can rotate, and indirect messenger goes out work or material rest 4 and takes place to rotate, and then adjusts the angle of the relative reservoir 1 of play work or material rest 4 to be 90 for discharge opening 44 when guaranteeing the copper line ejection of compact.
In addition, this embodiment still provides a scheme, promptly the one end of dead lever 52 is connected with an regulating plate 55, regulating plate 55 articulates on bobbin 51, dead lever 52 takes place to rotate for bobbin 51, and after the rigidity of play work or material rest 4, can adjust the height position of delivery wheel 53 through adjusting regulating plate 55 to the angle of being qualified for the next round of competitions of adjustment copper line makes copper line and discharge opening 44 be the ejection of compact of vertical direction.
The discharging angle of the copper wire and the discharging hole 44 can be adjusted by one of the three modes, so that the generation of a 'sun and shade surface' of the copper wire can be prevented during discharging, then the required effect can be achieved by combining any two modes or implementing the three modes together, the dispatching plate 45 and the conveying wheel 53 are adjusted to be trimmed at a large angle, the position of the wire pressing device is adjusted to be fine adjusted, the combined effect is better than that of the single use, and the primary and secondary adjusting functions are achieved; and thus should not be considered as limiting, but merely as enabling one of them.
It will be appreciated by persons skilled in the art that the embodiments of the invention described above and shown in the drawings are given by way of example only and are not limiting of the invention.
The objects of the invention have been fully and effectively accomplished. The functional and structural principles of the present invention have been shown and described in the examples, and any variations or modifications of the embodiments of the present invention may be made without departing from the principles.
