[0022] The present application will now be described in detail with reference to the accompanying drawings and optional embodiments.

[0023] Figure 1 This is a schematic diagram of a copper melting device according to an embodiment of this application, as shown below. Figure 1 As shown, this application discloses a copper melting device 10, which includes a tank structure 20 and a coil feeding structure 30. The coil feeding structure 30 is disposed on the tank structure 20 and includes a feeding bracket 100, a first fixing component 130, a second fixing component 140, and a conveying component 200. The feeding bracket 100 is connected to the tank structure 20. The first fixing component 130 and the conveying component 200 are both connected to the feeding bracket 100. The second fixing component 140 is slidably connected to the feeding bracket 100. The first fixing component 130 and the second fixing component 140 are disposed opposite to each other and are used to abut against the two ends of the coil roller, respectively. The tank structure 20 is provided with a feed inlet 21, and the conveying component 200 is used to convey the coiled material on the coil roller into the feed inlet 21.

[0024] For example, when the material on the roll is used up and the roll needs to be replaced, one end of the roll is first connected and fixed to the first fixing component 130. Then, by sliding the second fixing component 140, the distance between the first fixing component 130 and the second fixing component 140 is increased. Then, the other end of the roll is aligned with the second fixing component 140. Then, the second fixing component 140 is slid to decrease the distance between the first fixing component 130 and the second fixing component 140, so that the first fixing component 130 and the second fixing component 140 abut against the two ends of the roll, thereby realizing the material replacement process.

[0025] Compared to the existing method of fixing the coil roll with a flange, this application sets a first fixing component 130 and a second fixing component 140 on the feeding bracket 100, and the second fixing component 140 is slidably connected to the feeding bracket 100. In this way, the distance between the first fixing component 130 and the second fixing component 140 can be adjusted by sliding the second fixing component 140, thereby realizing a simple and fast material changing process. It does not require disassembling bolts or flanges to replace the coil roll, and the time consumption is short, thereby improving the material changing efficiency of the copper melting device 10.

[0026] Figure 2 This is a schematic diagram of a first fixing component and a second fixing component according to an embodiment of this application. Figure 3 This is a schematic diagram of a second fixing component according to an embodiment of this application, as shown below. Figure 2 and Figure 3 As shown, the first fixing component 130 includes a first mounting cylinder 131, which is connected to the feeding bracket 100.

[0027] The second fixing component 140 includes a second mounting cylinder 141, a storage cylinder 142, a spring 143, a slider 144, and a pull rod 145. The storage cylinder 142 is connected to the feeding bracket 100. The slider 144 is disposed inside the storage cylinder 142. The second mounting cylinder 141 passes through the feeding bracket 100 and is connected to the slider 144. The spring 143 is disposed inside the storage cylinder 142, and both ends of the spring 143 abut against the bottom of the slider 144 and the storage cylinder 142, respectively. The pull rod 145 passes through the storage cylinder 142 and is connected to the side of the slider 144 away from the second mounting cylinder 141.

[0028] The first mounting cylinder 131 and the second mounting cylinder 141 are respectively used to abut against the two ends of the roll.

[0029] When increasing the distance between the first mounting cylinder 131 and the second mounting cylinder 141, the pull rod 145 is pulled away from the first mounting cylinder 131. The pull rod 145 drives the slider 144 to move away from the first mounting cylinder 131. While moving, the slider 144 compresses the spring 143 and drives the second mounting cylinder 141 to move away from the first mounting cylinder 131, thereby increasing the distance between the first mounting cylinder 131 and the second mounting cylinder 141.

[0030] Then one end of the roll can be fixed to the first mounting cylinder 131. When the pull rod 145 is released, the elastic contraction of the spring 143 will drive the slider 144 and the second mounting cylinder 141 to move toward the first mounting cylinder 131, so that the other end of the roll is inserted into the second mounting cylinder 141.

[0031] The feeding bracket 100 includes a left fixing plate 110 and a right fixing plate 120. The left fixing plate 110 and the right fixing plate 120 are mounted on the tank structure 20. The first fixing component 130 is connected to the left fixing plate 110, and the second fixing component 140 is connected to the right fixing plate 120.

[0032] For example, the interior of the first mounting cylinder 131 is hexagonal, the interior of the second mounting cylinder 141 is hexagonal, and both ends of the winding roller are also hexagonal, thereby achieving better fixation and preventing the winding roller from rotating relative to the first mounting cylinder 131 and the second mounting cylinder 141.

[0033] Of course, the railing can also be controlled by methods other than manual operation. Specifically, the second fixing component 140 also includes a solenoid valve 300, which is mounted on the feeding bracket 100 and connected to the pull rod 145. The solenoid valve 300 drives the pull rod 145 to move, causing the slider 144 to slide within the receiving cylinder 142. By driving the pull rod 145 to move left and right through the solenoid valve 300, the distance between the first mounting cylinder 131 and the second mounting cylinder 141 can be controlled, thus improving the level of automation compared to manual operation.

[0034] See also Figure 2As shown, the conveying assembly 200 includes a first clamping roller 210, a first clamping roller shaft 220, a second clamping roller 230, a second clamping roller shaft 240, a first clamping roller gear 251, a second clamping roller gear 252, and a conveying drive motor 260. Both ends of the first clamping roller shaft 220 and both ends of the second clamping roller shaft 240 are respectively connected to the feeding bracket 100. The conveying drive motor 260 is connected to either the first clamping roller shaft 220 or the second clamping roller shaft 240. The first clamping roller 210 and the first clamping roller gear 251 are both connected to the first clamping roller shaft 220. The second clamping roller 230 and the second clamping roller gear 252 are both connected to the second clamping roller shaft 240, and the first clamping roller gear 251 and the second clamping roller gear 252 mesh. The first clamping roller 210 and the second clamping roller 230 are used to clamp the rolled material on the winding roller and feed it into the feed inlet 21.

[0035] The conveying drive motor 260 described in this application can be connected to the first clamping roller shaft 220, that is, the conveying drive motor 260 controls the rotation of the first clamping roller shaft 220. Of course, the conveying drive motor 260 can also be connected to the second clamping roller shaft 240, that is, the conveying drive motor 260 controls the rotation of the second clamping roller shaft 240. No limitation is made here. For the sake of explanation, this application takes the connection of the conveying drive motor 260 to the first clamping roller shaft 220 as an example.

[0036] The first clamping roller gear 251 and the second clamping roller gear 252 mesh, so that the conveying drive motor 260 can control the first clamping roller 210 and the second clamping roller 230 to rotate synchronously. Simply put, the first clamping roller 210 and the second clamping roller 230 clamp the rolled material on the winding roller, and when rotating, they feed the rolled material on the winding roller into the feed port 21.

[0037] Figure 4 This is a schematic diagram of a first and a second pinch roller according to an embodiment of this application, as shown below. Figure 4 As shown, since the thickness of the material on the roll is not uniform, the change in the thickness of the material during the conveying process will cause tension fluctuations, which will cause the material to wrinkle or break, thus interrupting the feeding process.

[0038] Therefore, this application designs the first clamping roller 210 to include a first clamping roller body 211 and a first clamping roller elastic part 212, the first clamping roller elastic part 212 being sleeved on the first clamping roller body 211, and the first clamping roller elastic part 212 being capable of elastic deformation; the second clamping roller 230 includes a second clamping roller body 231 and a second clamping roller elastic part 232, the second clamping roller elastic part 232 being sleeved on the second clamping roller body 231, and the second clamping roller elastic part 232 being capable of elastic deformation.

[0039] The first clamping roller elastic part 212 and the second clamping roller elastic part 232 can be made of rubber material, so that the first clamping roller elastic part 212 and the second clamping roller elastic part 232 can undergo elastic deformation. For example, when clamping the rolled material on the winding roller, when the rolled material changes from thin to thick, the first clamping roller elastic part 212 and the second clamping roller elastic part 232 can each contract inward to avoid breaking the rolled material and causing the feeding to be interrupted.

[0040] Furthermore, the first clamping roller elastic part 212 and the first clamping roller main body 211 are detachably connected, and the second clamping roller elastic part 232 and the second clamping roller main body 231 are detachably connected. Thus, if the first clamping roller elastic part 212 and the second clamping roller elastic part 232 are scratched by the rolled material, the first clamping roller elastic part 212 and the second clamping roller elastic part 232 can be replaced instead of replacing the entire first clamping roller 210 and the second clamping roller 230, thereby saving costs.

[0041] Since the thickness of the rolled material is generally between 2mm and 3mm, the thickness of the first clamping roller elastic part 212 and the second clamping roller elastic part 232 is 4mm-6mm, and the minimum distance between the first clamping roller elastic part 212 and the second clamping roller elastic part 232 is 1mm-2mm. Both the first clamping roller elastic part 212 and the second clamping roller elastic part 232 can undergo a thickness deformation of 1mm-2mm. This ensures that the first clamping roller elastic part 212 and the second clamping roller 230 have sufficient deformation, improving the reliability of feeding.

[0042] Figure 5 This is a schematic diagram of a first cutting structure according to an embodiment of this application, as shown below. Figure 5 As shown, the copper melting device 10 also includes a cutting structure 500, which is located on the side of the coil feeding structure 30 near the tank structure 20.

[0043] The cutting structure 500 includes a second cutting blade 510, a second cutting drive motor 520, and a cutting plate 530. The second cutting blade 510, the second cutting drive motor 520, and the cutting plate 530 are all connected to the feeding bracket 100, and the second cutting blade 510 and the cutting plate 530 are arranged opposite to each other. The second cutting drive motor 520 drives the second cutting blade 510 to move closer to and away from the cutting plate 530.

[0044] The second cutting drive motor 520 drives the second cutting blade 510 to move closer to and away from the cutting plate 530, thereby making the roll material easier to dissolve.

[0045] The copper melting device 10 further includes a tensioning structure 600, which is connected to the feeding bracket 100 and is located on the side of the coil feeding structure 30 near the tank structure 20. The tensioning structure 600 includes a third clamping roller 610, a third clamping roller shaft 620, a fourth clamping roller 630, a fourth clamping roller shaft 640, a third clamping roller gear 651, a fourth clamping roller gear 652, and a tensioning drive motor 660.

[0046] Both ends of the third clamping roller shaft 620 and both ends of the fourth clamping roller shaft 640 are respectively connected to the feeding bracket 100. The tensioning drive motor 660 is connected to the third clamping roller shaft 620 or the fourth clamping roller shaft 640. The third clamping roller 610 and the third clamping roller gear 651 are both connected to the third clamping roller shaft 620. The fourth clamping roller 630 and the fourth clamping roller gear 652 are both connected to the fourth clamping roller shaft 640, and the third clamping roller gear 651 and the fourth clamping roller gear 652 mesh. The third clamping roller 610 and the fourth clamping roller 630 are used to clamp the coil material coming out from the first clamping roller 210 and the second clamping roller 230.

[0047] For example, during the feeding process, the first clamping roller and the second clamping roller clamp the rolled material on the winding roller, and then the third clamping roller 610 and the fourth clamping roller 630 clamp the rolled material coming out from the first clamping roller 210 and the second clamping roller 230, thereby ensuring the tension of the rolled material between the first clamping roller and the second clamping roller and the third clamping roller 610 and the fourth clamping roller 630, so that the cutting structure 500 can cut the rolled material more easily.

[0048] Figure 6 This is a schematic diagram of another cutting structure according to an embodiment of this application, as shown below. Figure 6 As shown, the conveying assembly 200 further includes a first cutting blade 410, which is disposed on the first clamping roller 210 and protrudes from the side of the first clamping roller 210; the second clamping roller 230 is provided with a groove 420, and when the first clamping roller 210 rotates to the state where the first cutting blade 410 faces the second clamping roller 230, the first cutting blade 410 is partially located in the groove 420.

[0049] By setting a cutting blade on the first clamping roller 210, and the first cutting blade 410 protruding from the side of the first clamping roller 210, and the second clamping roller 230 being provided with a groove 420, when the first clamping roller 210 rotates to the state where the first cutting blade 410 faces the second clamping roller 230, the first cutting blade 410 is partially located in the groove 420, thereby cutting the clamped roll material. There is no need to set up an additional cutting structure 500, and the roll material can be cut during transportation.

Therefore, without conflict, the embodiments described above or the technical features can be arbitrarily combined to form new embodiments.
