Automatic tin cutting and feeding device

Abstract

The embodiment of the invention provides an automatic tin cutting and feeding device. The automatic tin cutting and feeding device comprises a box body, a guide mechanism, a cutting mechanism and a traction control mechanism, wherein the box body comprises a bottom plate, protective coamings, a cover plate, first through holes and second through holes; the guide mechanism comprises a tin wire inlet guide pipe and a tin wire outlet guide pipe which are fixed on the protective coamings and are symmetrically arranged; the cutting mechanism comprises a driving device, a rotating shaft assembly and a sectioning blade; and the traction control mechanism comprises a fixed shaft, a mounting plate, a dredging pressing wheel assembly, a clutch handle and a spring, the dredging pressing wheel assembly is arranged opposite to the sectioning blade at an interval along the central axis of the tin wire inlet guide pipe, and the clutch handle is used for controlling the dredging pressing wheel assembly to be close to or away from the sectioning blade. The automatic tin cutting and feeding device is easy to operate, and when tin wires are cut, the tin explosion phenomenon cannot happen.

Description

technical field [0001] The invention relates to the technical field of cutting and winding, in particular to an automatic tin cutting and feeding device. Background technique [0002] The tin-splitting and tin-feeding device is a very important tool in the electronics industry, and with the rapid development of the electronics industry, the performance requirements for the tin-splitting and tin-feeding device are gradually increasing. [0003] The current problems are: 1. The cutting blade used by the existing tin-slitting and tin-feeding device is either a disc blade or a zigzag circular blade. When the disc blade cuts the tin wire, the deformation of the tin wire is too large, causing the tin wire to be too Bending, causing the tin wire to have a lot of friction during transportation, which is easy to cause blockage; due to the processing limitation of the serrated circular blade, the span between the teeth is too large, resulting in low cutting volume of the tin wire, whi...

AI Technical Summary

Problems solved by technology

[0003] The current problems are: 1. The cutting blade used by the existing tin-slitting and tin-feeding device is either a disc blade or a zigzag circular blade. When the disc blade cuts the tin wire, the deformation of the tin wire is too large, causing the tin wire to be too Bending, causing the tin wire to have a lot of friction during transportation, which is easy to cause blockage; due to the processing limitation of the serrated circular blade, the span between the teeth is too large, resulting in a low cutting volume of the tin wire, which is easy to fry the tin

2. Most of the guide and pressure rollers of the existing tin-splitting and tin-feeding devices adopt optical axis hard grinding, which has high friction, fast wear, easy eccentricity, and short life

3. It is very difficult to operate the cutting blade of the existing dissecting tin-sending device and the clutch mode of the dredging pressure wheel, which increases the difficulty of using the device to a certain extent; 4. The cutting blade and the existing dissecting tin-sending device The spacing between the guide rollers is adjusted by the adjustment screw, which requires relatively high technical requirements. Improper adjustment may easily cause damage to the cutting blade and guide rollers.
