Detailed Implementation

[0029] The embodiments of this utility model will be described in more detail below with reference to the accompanying drawings and reference numerals, so that those skilled in the art can implement them after reading this specification. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0030] This utility model provides, for example Figure 1 , 2The diagram illustrates an automated metal ingot granulation production system that processes lead ingots or other metal ingots into granules. The automated metal ingot granulation production system includes a feeding module 10, a rolling module 20, a slitting module 30, and a pelletizing module 40 arranged sequentially, as well as a connecting channel 50 between the rolling module 20 and the slitting module 30. The feeding module 10, rolling module 20, slitting module 30, and pelletizing module 40 can all refer to related technologies. The rolling module 20 includes multiple rolls 22 rotatably connected to a frame 21 and a rolling discharge channel 24 disposed between adjacent rolls 22. Adjacent rolls 22 form a rolling operation section that rolls the lead ingots into lead strips. The slitting module 30 includes a slitting feed channel 31, through which the lead strip enters the slitting module 30 and is sheared into multiple lead strips. The connecting channel 50 is located between the rolling discharge channel 24 and the slitting feed channel 31. It is a square tubular structure formed by the bottom plate, side plates and top plate, and the lead strip passes through its inner cavity.

[0031] Please refer to Figure 3 , 4 A pair of clamping rollers are also provided at the end of the connecting channel 50 facing the slitting feed channel 31 to clamp the lead strip, serving as the feeding mechanism of the slitting module 30. The rotation of the clamping rollers provides thrust to the lead strip, stably feeding it through the slitting feed channel 31 into the space between the multiple cutting wheels of the slitting module 30, thereby solving the problem that the cutting wheels cannot smoothly engage the lead strip.

[0032] In this embodiment, the pair of clamping rollers includes a first clamping roller 51 and a second clamping roller 52. The base plate of the connecting channel 50 is rotatably connected to the first clamping roller 51 via a bracket, and the base plate is provided with a first through groove 53. The first clamping roller 51 extends into the connecting channel 50 from the first through groove 53 and contacts the lead strip. The rotating shaft of the first clamping roller 51 is also provided with a transmission gear 512, which is connected to a drive motor via a transmission chain or transmission gear, so that the drive motor drives the first clamping roller 51 to rotate. Further, the outer surface of the first clamping roller 51 is provided with a plurality of clamping teeth 511 extending along its axial direction to enhance the friction between the clamping roller and the lead strip. Both side plates of the connecting channel 50 are rotatably connected to rotating arms 54. The second clamping roller 52 is rotatably connected between the two rotating arms 54, and the distance between the second clamping roller 52 and the first clamping roller 51 can be flexibly adjusted to accommodate lead strips of different thicknesses. The top plate of the connecting channel 50 is provided with a second through groove 55 corresponding to the second clamping roller 52. The second clamping roller 52 extends into the connecting channel 50 from the second through groove 55 and contacts the lead strip, applying its gravity to the lead strip to achieve clamping.

[0033] In this embodiment, please refer to Figure 1The feeding module 10 includes a chain conveyor 11, a lifting device 12 disposed at one end of the chain conveyor 11, and a rolling feed device 13 disposed above the lifting device 12. The chain conveyor 11 transports the lead ingots to above the lifting device 12, the lifting device 12 transports the lead ingots upward to be flush with the rolling feed device 13, and then the rolling feed device 13 transports the lead ingots to the rolling module 20.

[0034] Please refer to Figure 5 The lifting device 12 includes a lifting cylinder 121, the piston rod of which is connected to a roller frame 122. The roller frame 122 includes multiple rotatable rollers to reduce resistance when the lead ingot moves. The roller frame 122 is provided with a U-shaped groove 123 corresponding to the chain of the chain conveyor 11, so that the roller frame 122 avoids interference with the conveyor chain of the chain conveyor 11 when it rises. A limiting member 124 bolted to the chain conveyor 11 is also provided on one side of the roller frame 122 to hold the lead ingot on the roller frame 122. The rolling feed device 13 includes a rolling feed cylinder 131 for pushing metal ingots from the idler roller 122 into the rolling module 20. The lifting cylinder 121 pushes the idler roller 122 up until the lead ingot is flush with the rolling feed cylinder 131. Then the rolling feed cylinder 131 extends to transport the lead ingot along the idler roller 122 into the rolling feed channel 23 of the rolling module 20.

[0035] Please refer to Figure 2 , 7 The rolling module 20 includes the frame 21 and three rolls 22 rotatably connected to the frame 21. The rolls 22 include a first roll 22a, a second roll 22b, and a third roll 22c. The rotating shafts of the three rolls are equipped with transmission gears. The first roll 22a is connected to the second roll 22b via the transmission gears. The second roll 22b is connected to the third roll 22c via the transmission gears. The third roll 22c is connected to a drive motor, which drives the first, second, and third rolls to rotate.

[0036] The first roll 22a and the second roll 22b form a rolling operation section. A rolling feed channel 23 is provided between the first roll 22a and the second roll 22b, which corresponds to the rolling feed cylinder 131. The lead ingot enters the space between the first and second rolls through the rolling feed channel 23 to complete one rolling operation, and the rolling operation section also pushes the lead ingot forward. The second roll 22b and the third roll 22c also form a rolling operation section. A rolling discharge channel 24 is also provided between the second roll 22b and the third roll 22c. After the lead ingot completes a second rolling operation, it is sent out of the rolling module from the rolling discharge channel 24 by the rolling operation section. The minimum distance between the first roll 22a and the second roll 22b is greater than the minimum distance between the second roll 22b and the third roll 22c. The two rolling operations reduce the thickness of the lead ingot sequentially, eventually forming a lead strip.

[0037] Preferably, the diameter of the roll 22 is 450 mm and the width is 170 mm; the minimum distance between the first roll 22a and the second roll 22b is 48 mm, and the minimum distance between the second roll 22b and the third roll 22c is 18-20 mm; the width of the rolling feed channel 23 is 132 mm, and the width of the rolling discharge channel 24 is 135-145 mm. The design of these dimensions is based on a combination of the ductility characteristics of lead, lead granule weight requirements and normal distribution requirements, a production capacity requirement of 8 tons / hour, and roll speed requirements.

[0038] The rolling module 20 also includes a transfer device 25 to transfer the lead ingots between two rolling operations. Please refer to... Figure 6 , 7 The transfer device 25 includes a bracket 251 connected to the frame 21. The bracket 251 is provided with two vertically arranged baffles 252. A material carrier 253 is rotatably connected between the two baffles 252. A lifting cylinder 254 is provided between the material carrier 253 and the bracket 251. The two ends of the lifting cylinder 254 are respectively hinged to the material carrier 253 and the bracket 251. When the lifting cylinder 254 extends or retracts, it can drive the material carrier 253 to rotate relative to the two baffles 252, so that the material carrier 253 faces the rolling feed channel 23 and the rolling discharge channel 24 respectively. A pusher cylinder 255 is also provided on the outer side of the baffle 252. The piston rod of the pusher cylinder 255 is provided with a pusher head 256 extending between the two baffles 252. The baffle 252 is provided with a through groove corresponding to the pusher head 256 to prevent the pusher head 256 from colliding with the baffle when it moves. The pusher head 256 passes through the through groove and is connected to the piston rod of the pusher cylinder 255.

[0039] When the material carrier 253 is oriented toward the rolling feed channel 23, such as Figure 8As shown in the dotted line, under the push of the rolling mill, the lead ingot, after one rolling process, slides down to the carrier frame 253 under its own gravity and is limited by the pusher head 256; then the lifting cylinder 254 retracts, making the carrier frame 253 flush with the rolling discharge channel 24, and the pusher cylinder 255 retracts, pushing the lead ingot into the rolling discharge channel 24 to enter the second rolling mill 22b and the third rolling mill 22c to complete the secondary rolling to form a lead strip. Finally, the lead strip leaves the rolling module 20 along the rolling discharge channel 24 under the push of the second and third rolling mills and enters the connecting channel 50.

[0040] Please refer to Figure 8 The slitting module 30 includes a slitting feed channel 31, a slitting device 32, and a discharge guide device 33. A pair of clamping rollers connected to the channel 50 serve as the feeding mechanism. The lead strip is pushed by the pair of clamping rollers and fed into the slitting device 32 through the slitting feed channel 31. After being cut into multiple lead strips by the slitting device 32, it is sent out from the discharge guide device 33.

[0041] The slitting device 32 includes a pair of rotatable cutting rollers 321. The pair of cutting rollers 321 are respectively provided with two top cutting wheels 322 and three bottom cutting wheels 323 along the axial direction. The top cutting wheels 322 and the bottom cutting wheels 323 are arranged at intervals and staggered in sequence. The lead strip enters between the top and bottom cutting wheels and is cut into 5 lead strips, which are discharged from 3 gaps near the 2 top cutting wheels and 2 gaps between the 3 bottom cutting wheels.

[0042] Both the slitting feed channel 31 and the discharge guide device 33 are located between the top cutting wheel 322 and the bottom cutting wheel 323. The slitting feed channel 31 is a square tubular shape. Please refer to... Figure 9 , 10The discharge guiding device 33 includes a discharge guiding pipe 331, three bottom guide strips 332 disposed on the bottom plate of the discharge guiding pipe 331, and two top guide strips 333 disposed on the top plate of the discharge guiding pipe 331. The discharge guiding pipe 331 is a square tubular structure formed by a bottom plate, a top plate, and two side plates. The three bottom guide strips 332 and the two top guide strips 333 are arranged at intervals along the axial direction of the cutting roller 321. A bottom guide groove 334 is provided between two adjacent bottom guide strips 332, forming a total of two bottom guide grooves. A top guide groove 335 is provided between two adjacent top guide strips 333 and between a top guide strip 333 and an adjacent side plate of the discharge guiding pipe 331, forming a total of three top guide grooves. Furthermore, the gap between any two adjacent bottom cutting wheels 323 corresponds to a bottom guide groove 334, through which the lead strip exiting the gap is supported by the bottom plate of the discharge guide tube 331 and enters the bottom guide groove 334; the gaps on both sides of the top cutting wheel 322 correspond to a top guide groove 335, through which the lead strip exiting the gap is supported by the bottom guide bar 332 and enters the top guide groove 335. Driven by the top and bottom cutting wheels, the five lead strips enter the two bottom guide grooves 334 and the three top guide grooves 335 respectively, guiding each lead strip to the pelletizing module 40.

[0043] Preferably, please refer to Figure 10 The top guide strip 333 has a first curved surface 3331 at one end facing the cutting roller 321. The first curved surface 3331 is in clearance fit with the top cutting wheel 322, allowing the top guide strip 333 to extend to the vicinity of the top cutting wheel 322, filling the gap between them as much as possible and preventing the lead strip from getting stuck in the gap. The bottom guide strip 332 has a second curved surface 3321 at one end facing the cutting roller 321. The second curved surface 3321 is in clearance fit with the bottom cutting wheel 323, allowing the bottom guide strip 332 to extend to the vicinity of the bottom cutting wheel 323, filling the gap between them as much as possible and preventing the lead strip from getting stuck in the gap.

[0044] Please refer to Figure 11 , 12 The pelletizing module 40 includes a pelletizing device 41 and a pelletizing feeder 42. The pelletizing device 41 includes a rotating shaft 411 and five cutter discs 412 sequentially arranged along the axial direction of the rotating shaft 411. The rotating shaft 411 is connected to a drive motor, which drives the cutter discs 412 to rotate. Each cutter disc 412 has nine cutters 413 symmetrically arranged about the central axis of the rotating shaft 411. Specifically, each cutter disc 412 has nine slots into which the cutters 413 are inserted and bolted to the cutter disc 412.

[0045] The cutting blades 413 on any one of the cutting discs 412 are staggered from those on other cutting discs 412. During the shearing process, only one cutting blade 413 on the pelletizing module 40 is shearing one lead strip at a time, which greatly reduces the impact force on the pelletizing device during the shearing operation and extends its service life. In this embodiment, the rotating shaft 411 includes a connecting part with a regular decagonal cross-section. The five cutting discs 412 cooperate with the connecting part. When installing the cutting discs, multiple cutting discs can be rotated relative to each other by 32.727° in sequence and then fitted onto the connecting part, so that all cutting blades are staggered.

[0046] The pelletizing and feeding device 42 includes a pair of relatively rotating feed rollers 421 and a feed guide device disposed between the pair of feed rollers 421. The axial direction of the feed rollers 421 is parallel to the rotation shaft 411. The feed rollers 421 clamp the lead strip and push it towards the pelletizing device 41 by rotation. Please refer to... Figure 13 The feeding guide device includes a feeding guide pipe 423 formed by a bottom plate, side plates, and a top plate. The feeding guide pipe 423 extends from the side of the feeding roller 421 away from the pelletizing device 41 to the side of the feeding roller 421 facing the pelletizing device 41. The feeding guide pipe 423 also has multiple grooves, into which two insertion pipes 424 are inserted and bolted to the feeding guide pipe 423 for reinforcement. The top and bottom of the feeding guide pipe 423 and the insertion pipes 424 are provided with clearance grooves 425 that respectively cooperate with a pair of feeding rollers 421, allowing the pair of feeding rollers 421 to contact the lead strip.

[0047] Two insertion tubes 424 extend axially along the feed guide tube 423. Spacing is provided between adjacent insertion tubes 424 and between each insertion tube 424 and the side plate of the adjacent feed guide tube 423. These three spacings, along with the inner cavities of the two insertion tubes 424, together form five parallel guide channels 422. The guide channels 422 extend from the side of the feed roller 421 away from the pelletizing device 41 to the side of the feed roller 421 facing the pelletizing device 41. One end of each of the five guide channels 422 corresponds to one of the five cutter discs 412, and the other end corresponds to one of the two bottom guide grooves 334 and one of the three top guide grooves 335.

[0048] Five lead strips from two bottom guide grooves 334 and three top guide grooves 335 enter five guide channels 422 respectively. Under the clamping and conveying of a pair of feeding rollers, they emerge from the guide channels 422 toward one end of the pelletizing device 41. The five lead strips correspond to five cutter discs respectively, completing the accurate feeding of each cutter disc 412, avoiding the lead strips from skewing during feeding, and making the cut lead pellets more regular.

[0049] The above describes one or more embodiments of this utility model in a relatively specific and detailed manner, but it should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
