In the process of reusing old tinned copper wires, precise cutting and straightening are crucial pretreatment steps. Traditionally, these steps are often carried out separately, which is not only inefficient, but also difficult to ensure the consistency and quality of the treatment. Summary of the invention

When driven by the motor, the rotating rod rotates and the convex rod slides in the elongated ring to realize the horizontal movement of the elongated ring; a rack plate is provided on the elongated ring, the rack plate is meshed with the gear, a rotating rod is provided on the gear, and a rotating plate is provided on the upper end of the rotating rod.

[0006] Preferably, the pressing and cutting assembly includes a second support plate, a connecting plate, a first push plate, a second push plate, a first pressure plate and a cutter; two second support plates are provided between the opposite ends of the upper support plate, the lower end of the second support plate is provided with a connecting plate that forms a sliding connection with the second support plate, the upper end of the second support plate is slidably provided with a first push plate, and the first push plate is driven to reciprocate under the push of the rotating plate; second push plates are respectively provided at both ends of the first push plate, and the second push plate is provided with a first pressure plate, and cutters are provided on the two first pressure plates.

[0007] Preferably, a push groove is provided on the first push plate; a push block is provided on the rotating plate, and the push block cooperates with the push groove.

[0008] Preferably, two sliding rods are provided on the long ring, and the lower ends of the sliding rods are slidably connected with the bottom plate to support the sliding rods; a support rod is sleeved on the outer side of the rotating rod, and a first support plate is provided on the support rod, and the upper end of the first support plate is connected with one of the upper support plates to support the rotating rod.

[0009] Preferably, a third pressing plate is provided on the upper supporting plate, and a cutting groove is formed on the third pressing plate, and the cutting groove cooperates with the cutting knife.

[0010] Preferably, three second pressure plates are slidably provided on the upper support plate, the cutter is located between two short second pressure plates, a spring is provided on the second pressure plate, a spring support plate is provided on the spring, and the spring support plate is mounted on the upper support plate.

[0011] Preferably, a short rod is provided between the two short second pressing plates to form the two short second pressing plates into a whole so as to facilitate resetting by pulling of a spring.

[0012] Preferably, a through groove is provided on the upper supporting plate, and at least two rollers are rotatably provided in the through groove.

[0013] A method for recovering copper and tin from waste tinned copper wire comprises the following steps:

[0014] S1. First, put the recycled old tinned copper wire onto the roller. As the roller slowly rolls, its friction will effectively drive the old tinned copper wire forward along the predetermined path, preparing for the subsequent processing steps.

[0015] S2. When the old tinned copper wire moves steadily to a certain position, the motor is started, the motor responds quickly, and transmits power to the rotating rod, causing the rotating rod to start rotating. A convex rod is installed on the rotating rod, and the convex rod is embedded in the track of the long ring. Therefore, during the rotation of the rotating rod, the convex rod pushes the long ring like a piston, so that it can achieve stable and continuous reciprocating movement in the horizontal direction.

[0016] S3. One end of the long ring is connected to the rack plate. When the long ring moves, the rack plate also reciprocates. At the same time, the gear meshing with the rack plate starts to work. With each reciprocation of the rack plate, the gear will rotate forward and reverse accordingly. This flexible rotation mode makes subsequent power transmission possible.

[0017] S4. The rotating plate is closely connected to the gear through the gear rod, ensuring that each positive and negative rotation of the gear can be accurately converted into the reciprocating motion of the rotating plate. As the rotating plate swings back and forth, the two first push plates are effectively driven, and they also start regular reciprocating motion. The two first push plates not only play the role of transmitting power, but are also cleverly connected to the cutter and the first pressure plate. Therefore, under their push, the cutter and the first pressure plate can reciprocate, and finally achieve accurate cutting of the old tinned copper wire. This process is not only efficient, but also ensures the flatness and accuracy of the cut surface, providing a strong guarantee for subsequent reuse.

[0018] S5. Select a detinning agent according to the specific conditions of the copper wire, and immerse the cut and corrected tinned copper wire in the detinning liquid to remove the tin from the copper wire.

[0019] S6. After the detinning is completed, the detinning agent and other impurities on the surface of the copper wire need to be cleaned. The cleaned and neutralized copper wire needs to be dried to remove moisture from the surface.

[0020] The positive effects of this application are:

[0021] The device and method for recovering copper and tin from waste tinned copper wire provided by the embodiment of the present invention have the following advantages:

[0022] 1. By cutting and correcting the old tinned copper wire at the same time, the length of the old tinned copper wire cut at the same time is consistent, so that it can be more fully exposed to the detinning liquid, ensuring that the tin layer is removed evenly and quickly. The corrected tinned copper wire is arranged neatly, reducing the difficulty of handling caused by bending and winding, and improving the fluency and efficiency of the detinning operation.

[0035] Preferably, the pressing and cutting assembly includes a second support plate 3, a connecting plate 31, a first push plate 32, a second push plate 4, a first pressure plate 41 and a cutter 42; two second support plates 3 are provided between the opposite ends of the upper support plate 13, the lower end of the second support plate 3 is provided with a connecting plate 31 which is slidably connected to the second support plate 3, the upper end of the second support plate 3 is slidably provided with a first push plate 32, and the first push plate 32 is driven to reciprocate under the push of the rotating plate 27; second push plates 4 are respectively provided at both ends of the first push plate 32, and a first pressure plate 41 is provided on the second push plate 4, wherein two first pressure plates 41 are provided with cutters 42.

[0036] Preferably, a push groove 321 is provided on the first push plate 32 ; a push block 271 is provided on the rotating plate 27 , and the push block 271 cooperates with the push groove 321 .

[0037] Preferably, two sliding rods 22 are provided on the long ring 23, and the lower ends of the sliding rods 22 are slidably connected with the bottom plate 1 to support the sliding rods 22; a support rod 28 is sleeved on the outer side of the rotating rod 26, and a first support plate 11 is provided on the support rod 28, and the upper end of the first support plate 11 is connected to one of the upper support plates 13 to support the rotating rod 26.

[0038] Preferably, a third pressing plate 46 is provided on the upper support plate 13, and a cutting groove 461 is formed on the third pressing plate 46, and the cutting groove 461 cooperates with the cutter 42; three second pressing plates 43 are slidably provided on the upper support plate 13, two of which are short second pressing plates 43 and one is a long second pressing plate 43, and the cutter 42 is located between the two short second pressing plates 43, and a spring 44 is installed on each of the two short second pressing plates 43, and two springs 44 are provided on the long second pressing plate 43, and a spring supporting plate 45 is provided at one end of the spring 44 away from the second pressing plate 43, and the spring supporting plate 45 is installed on the upper support plate 13; a short rod 47 is provided between the two short second pressing plates 43, so as to form the two short second pressing plates 43 into a whole, so as to facilitate the spring 44 to pull and reset;

[0039] like Figure 2 , 3 As shown, when the rack plate 24 moves forward driven by the motor 2, the rotating plate 27 closely connected thereto will rotate clockwise therewith, and the push block 271 on the rotating plate 27 will precisely mesh with the push groove 321 at the rear, thereby converting the linear motion of the rack plate 24 into the rotational motion of the rotating plate 27, and further driving the first push plate 32 at the rear to move rightward. As the first push plate 32 moves rightward, the first pressure plate 41 at the rear right side connected thereto also moves rightward synchronously. This series of motions constitutes a complete transmission chain.

[0040] The rightward movement of the first pressing plate 41 not only changes its own position, but more importantly, produces an extrusion effect on the second pressing plate 43. This extrusion makes the second pressing plate 43 and the third pressing plate 46 form a close fit, just like a pair of powerful hands, firmly clamping and correcting the bent old tinned copper wire, which not only restores the original shape of the old tinned copper wire, but also lays a solid foundation for its subsequent processing.

[0041] As the rotating plate 27 continues to rotate clockwise, the push block 271 will engage with the front push groove 321. This change once again demonstrates the flexibility and accuracy of mechanical transmission, which pushes the first push plate 32 in the front to move leftward, thereby driving the cutter 42 on the left side in the front to move leftward. The precise movement of the cutter 42 is like a pair of sharp scissors, accurately cutting off the old tinned copper wire on the roller 14. The completion of this step indicates that the old tinned copper wire has been successfully cut into the required length.

[0042] When the rack plate 24 moves backward, the entire system will operate in the opposite way. At this time, the rotating plate 27 will rotate counterclockwise, driving the second pressure plate 43 on the front right side to move to the right. This action not only helps to cut off another section of old tinned copper wire on the roller 14, but also ensures that the copper wire after cutting will not interfere with the subsequent processing due to residue. At the same time, the second pressure plate 43 on the rear left side will cooperate with the third pressure plate 46 again to correct the other bent section of old tinned copper wire.

[0043] Through this ingeniously designed and precisely moving mechanical transmission system, not only can the old tinned copper wire be cut off and corrected simultaneously, but the work efficiency is also greatly improved. More importantly, this processing method ensures the stability and reliability of the entire process, providing a strong guarantee for the reuse of old tinned copper wire.

[0044] By cutting and correcting the old tinned copper wire at the same time, the length of the old tinned copper wire cut at the same time is consistent, so that it can be more fully exposed to the detinning liquid, ensuring that the tin layer is removed evenly and quickly. The corrected tinned copper wire is arranged neatly, reducing the difficulty of handling due to bending, entanglement, etc., and improving the smoothness and efficiency of the detinning operation.

[0045] At the same time, during the cutting and correction process, the damage, oxide layer and irregular parts on the surface of the tinned copper wire can be removed. These parts are easy to fall off or cause copper loss during the detinning process. The neatly arranged tinned copper wires can reduce friction and collision between each other during detinning, thereby reducing the loss rate of copper materials.

[0046] The tinned copper wire after cutting is easier to control the detinning time, ensuring that the tin layer is completely removed without excessive corrosion of the copper matrix. The corrected tinned copper wire can maintain a stable shape during the detinning process, avoiding uneven detinning or damage to the copper matrix due to irregular shape.

[0047] Furthermore, the cut and corrected tinned copper wire is easier to carry out subsequent processing steps such as cleaning, drying, and recycling. The neatly arranged tinned copper wire can reduce the difficulty of operation and time cost in the subsequent processing and improve the overall production efficiency.

[0048] Preferably, a through groove 12 is provided on the upper support plate 13, and at least two rollers 14 are rotatably provided in the through groove 12. The arrangement of the rollers 14 not only supports the old tinned copper wire, but more importantly, the rolling of the rollers 14 greatly reduces the friction resistance of the old tinned copper wire during movement, making the transmission process smoother and more unobstructed, thereby improving the transmission efficiency.

[0049] First, the recycled old tinned copper wire is placed on the roller 14. As the roller 14 slowly rolls, its friction will effectively drive the old tinned copper wire to move forward along a predetermined path, preparing for subsequent processing steps.

[0050] When the old tinned copper wire moves steadily to a certain position, the motor 2 is started, the motor 2 responds quickly, and transmits power to the rotating rod 21, so that the rotating rod 21 starts to rotate. A convex rod is installed on the rotating rod 21, and the convex rod is embedded in the track of the long ring 23. Therefore, during the rotation of the rotating rod 21, the convex rod pushes the long ring 23 like a piston, so that it can achieve stable and continuous reciprocating movement in the horizontal direction.

[0051] One end of the long ring 23 is connected to the rack plate 24. When the long ring 23 moves, the rack plate 24 also reciprocates. At the same time, the gear 25 meshing with the rack plate 24 starts to work. With each reciprocation of the rack plate 24, the gear 25 will rotate forward and reverse accordingly. This flexible rotation mode makes subsequent power transmission possible.

[0052] The rotating plate 27 is closely connected to the gear 25 through the gear rotating rod 26, ensuring that each forward and reverse rotation of the gear 25 can be accurately converted into the reciprocating motion of the rotating plate 27. As the rotating plate 27 swings back and forth, the two first push plates 32 are effectively driven, and they also start regular reciprocating motion. The two first push plates 32 not only play the role of transmitting power, but are also cleverly connected to the cutter 42 and the first pressing plate 41. Therefore, under their push, the cutter 42 and the first pressing plate 41 can reciprocate, and finally achieve accurate cutting of the old tinned copper wire. This process is not only efficient, but also ensures the flatness and accuracy of the cut surface, providing a strong guarantee for subsequent reuse.

[0053] Select the detinning agent according to the specific situation of the copper wire, and immerse the cut and corrected tinned copper wire in the detinning liquid to make the tin fall off the copper wire.

[0054] After detinning is completed, the detinning agent and other impurities on the surface of the copper wire need to be cleaned. The cleaned and neutralized copper wire needs to be dried to remove moisture from the surface.

[0055] It is to be understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of the present invention, but the present invention is not limited thereto. For those of ordinary skill in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
