Referring to fig. 2, an annular groove 211 is formed in a peripheral side wall of one end, away from the gear set, of the driving disc 21, the tin cutting knife group 2 further includes a first knife ring 22 and a second knife ring 23 which are sleeved on a groove wall of the annular groove 211, the first knife ring 22 and the second knife ring 23 are both in a circular ring shape, and are parallel to each other, and central axes of the first knife ring 22 and the second knife ring 23 and a rotation axis of the driving disc 21 are located on the same straight line. The first cutter ring 22 and the second cutter ring 23 are respectively in key connection with the groove wall of the annular groove 211 and can be separated, so that the first cutter ring 22 and the second cutter ring 23 can be conveniently replaced when either or both of the first cutter ring 22 and the second cutter ring 23 are broken, and the service life of the tin splitting device is prolonged. In another embodiment, the first knife ring 22 and the second knife ring 23 are welded and fixed, and at this time, the first knife ring 22 and the second knife ring 23 are mutually supported, so that the structural strength is improved, and the phenomenon of knife breakage caused by the reaction force of a tin wire when the first knife ring 22 and the second knife ring 23 are cut is avoided.
When the first knife ring 22 and the second knife ring 23 are in key connection with the groove wall of the annular groove 211, the first knife ring 22 and the second knife ring 23 are coaxially fixed with the driving disc 21, so that the first knife ring 22 and the second knife ring 23 are driven to rotate by the driving disc 21 to cut a passing tin wire. And a plurality of gear teeth 24 are arranged on the outer peripheral edges of the first cutter ring 22 and the second cutter ring 23 at intervals, cutting edges are formed at the edges of the gear teeth 24, the common thickness of the first cutter ring 22 and the second cutter ring 23 decreases progressively along the direction deviating from the rotation axis, and the cutting edges of the first cutter ring 22 and the second cutter ring 23 are mutually attached.
When the first knife ring 22 and the second knife ring 23 cut the tin wire, the gear teeth 24 distributed at intervals cut the tin wire through sharp cutting edges and reach the position of the soldering flux inside the tin wire, so that the soldering flux is exposed, the pressure on the soldering flux is reduced, and the later-stage tin bead sputtering phenomenon is reduced. During the period, the gear teeth 24 are embedded into the solder wire and meshed with the solder wire, so as to drive the solder wire to stably transmit, thereby preventing the solder supply from being delayed to influence the solder quality.
Referring to fig. 2 and 3, the teeth 24 of the first cutter ring 22 and the second cutter ring 23 are circumferentially staggered along the driving disc 21, that is, the tooth spaces 241 formed between the adjacent teeth 24 of the first cutter ring 22 are opposite to the teeth 24 of the second cutter ring 23, and the tooth spaces 241 formed between the adjacent teeth 24 of the second cutter ring 23 are opposite to the teeth 24 of the first cutter ring 22. When the cutting edge of the gear teeth 24 of the first blade ring 22 cuts the solder wire, the gear teeth 24 of the second blade ring 23 enter the cut-open gap of the solder wire and engage with the solder wire, thereby pushing the solder wire to be conveyed forward. Similarly, the edge of the gear 24 of the second knife ring 23 pushes the edge of the gear 24 of the first knife ring 22 to forward the solder wire when the solder wire is cut, so that the continuous cutting and propelling of the solder wire are realized, and the conveying efficiency of the solder wire is improved. And the gear teeth 24 of the first knife ring 22 are opposite to the gear grooves 241 of the second knife ring 23, so that the thickness of the cutting edge is reduced, the tin wire is conveniently cut open, and the phenomenon that the normal use of the tin wire is influenced due to the fact that the tin wire is torn due to the fact that the cutting edge is too wide is avoided.
And the width of the tooth space 241 formed by the adjacent gear teeth 24 is less than or equal to the width of the gear teeth 24, so that the corners of the gear teeth 24 of the first knife ring 22 are abutted with the corners of the adjacent gear teeth 24 of the second knife ring 23, and the cutting edges of the adjacent gear teeth 24 of the first knife ring 22 and the second knife ring 23 are connected in a front-back manner, so that the gear teeth 24 can always cut a tin wire, burrs on the tin wire are prevented from being cut, the phenomenon that the burrs are blocked at the gaps of the cutting edges of the gear teeth 24 and influence the normal transmission of the tin wire is avoided, meanwhile, the cut gaps of the tin wire are kept coherent, the phenomenon that part of soldering flux is blocked and burst is avoided, and the phenomenon that tin balls are sputtered is reduced. The width of the tooth groove 241 is decreased progressively along the depth direction of the tooth groove 241, that is, the tooth groove 241 is in a V shape, so that the clamping force of the soldering flux embedded in the tooth groove 241 is reduced, the soldering flux is convenient to separate from the tooth groove 241, and the phenomenon that the first cutter ring 22 and the second cutter ring 23 are blocked is avoided. Meanwhile, the gear teeth 24 are trapezoidal, so that the structural strength of the root parts of the gear teeth 24 is enhanced, and the phenomenon of cutter breakage is reduced.

One end of the hand lever 31 is provided with a circular groove for inserting the rotating shaft 3, when the rotating shaft 3 is inserted into the circular groove, the opening edge of the circular groove abuts against the second knife ring 23, at this time, the second knife ring 23 abuts against the first knife ring 22, and the first knife ring 22 abuts against the inner wall of the annular groove 211, so that the first knife ring 22 and the second knife ring 23 are pressed tightly through the hand lever 31.
A bolt 32 passes through the hand lever 31 along the radial direction of the rotating shaft 3, one end of the bolt is abutted against the guide surface of the rotating shaft 3, and the bolt 32 is in threaded connection with the hand lever 31, so that the hand lever 31 and the rotating shaft 3 are coaxially fixed, and an operator can conveniently and manually adjust the driving disc 21 when the tin wire is jammed, so that the tin wire is recovered to a normal transmission state. When the bolt 32 rotates, one end of the bolt presses the guide surface, so that the hand lever 31 is pushed by the component force of the pressure to move towards the second cutter ring 23 and tightly abuts against the second cutter ring 23, thereby locking the first cutter ring 22 and the second cutter ring 23. The bolt 32 can prevent the gap between the second blade ring 23 and the first blade ring 22 from being too large to affect the cutting of the solder wire, and prevent the second blade ring 23 and the first blade ring 22 from losing the mutual supporting effect to cause the blade breaking phenomenon.
The limiting conveying wheel 4 is in the shape of a circular wheel, a ring groove is formed in the peripheral side wall of the limiting conveying wheel in a surrounding mode, the radial section of the ring groove is in a U shape and is equal to the width of a tin wire used by the automatic tin soldering machine, and a tin conveying channel 43 for conveying the tin wire is formed between the inner wall of the ring groove and the driving disc 21. The gear teeth 24 of the first knife ring 22 and the second knife ring 23 extend into the tin feeding channel 43 to cut the tin wire in the tin feeding channel 43, and the minimum distance between the cutting edge of the gear teeth 24 and the bottom wall of the ring groove is between the radius and the diameter of the tin wire, so that the thickness of a part of the tin wire is reserved while the soldering flux is exposed, the phenomenon that the tin wire is forked when the tin wire is close to a soldering iron head due to penetration is avoided, and the influence of the bifurcation of the tin wire on the tin feeding quality is avoided.
The gear train is connected with spacing conveying wheel 4 and rotates in order to drive spacing conveying wheel 4 through the motor, and spacing conveying wheel 4 drives the tin line through the inner wall of annular and the frictional force of tin line and transmits forward, and then realizes the pay-off of tin line. And the circumferential side wall of the limiting conveying wheel 4 is positioned at the tin feeding channel 43, namely, a plurality of strip-shaped convex patterns 431 are arranged on the inner wall of the ring groove at intervals.
