Description

Technical Field

[0001] This invention relates to the field of electrolysis technology, and more specifically to an electrolytic lead plate crushing device with automatic feeding function. Background Technology

[0002] In the production process of electrolytic lead, after the electrolysis process is completed, the electrolytic lead plate usually needs to be broken into pieces of a certain size so that it can be used as raw material for subsequent smelting, refining or other processes.

[0003] Currently, most traditional lead-aluminum sheet crushing devices employ simple roller extrusion or hammer crushing structures. Their feeding methods often rely on manual assistance, resulting in high labor intensity, low production efficiency, and safety hazards during manual operation. Furthermore, due to the inherent toughness, smooth surface, and uneven thickness of lead-aluminum sheets, existing automatic feeding mechanisms are prone to sheet misalignment, stacking, or jamming during transport, leading to discontinuous feeding and impacting the stability and capacity of the crushing operation. In addition, the existing crushing devices often feature a single, uniformly angled cutter head structure. When shearing lead-aluminum sheets, all blades participate in cutting simultaneously, resulting in a large instantaneous impact load. This not only easily causes drive motor overload and cutter head jamming but also leads to adhesion and blade sticking due to severe compression between the lead material and the blades. This results in unevenly sized fragments, difficulty in discharge, and in severe cases, frequent shutdowns for cleaning, hindering the continuous and automated operation of the production line. Summary of the Invention

[0007] Preferably, the guide bar is provided with parallel sections and inclined sections, the spacing of the inclined sections decreases along the movement direction of the lead plate, and the feed plate is also provided with a through-hole.

[0008] Preferably, the rotating rod is rotatably mounted on the upper housing, and a fixed roller is fixedly mounted on the surface of the rotating rod. The fixed roller is located inside the through-hole. There are two rotating rods, and a floating roller is fixedly mounted on the surface of the rotating rod.

[0009] Preferably, a movable component is provided on each of the left and right sides of the upper housing. The movable component includes a positioning shaft, a first gear, a second gear, a support frame, a steel chain, and a floating component. The positioning shaft is rotatably mounted on the upper housing, the support frame is fixedly mounted on the upper housing, and a tensioning wheel is rotatably mounted on the support frame.

[0010] Preferably, the first gear is fixedly mounted on the surface of the rotating rod, the second gear is fixedly mounted on the surface of the positioning shaft, the first gear and the second gear are meshed and connected, and a drive wheel is also fixedly mounted on the surface of the positioning shaft.

[0011] Preferably, the floating components are disposed at both ends of the rotating rod, and four floating components are disposed accordingly. Each floating component includes a fixed frame, a moving plate, and a driven wheel. The fixed frame is fixedly installed on the upper housing and has a strip-shaped hole. A guide rod is fixedly installed in the strip-shaped hole. The moving plate is sleeved on the surface of the guide rod, and a compression spring is sleeved on the surface of the guide rod. The rotating rod is rotatably mounted on the moving plate, and the driven wheel is fixedly installed at the end of the rotating rod. The steel chain is located between the driving wheel and the two driven wheels.

[0012] Preferably, the crushing mechanism includes a mounting shaft, which is rotatably mounted on the lower housing. Large cutter discs and small cutter discs are fixedly mounted on the surface of the mounting shaft. Multiple large cutter discs are evenly arranged, and small cutter discs are evenly distributed in the interval areas between the large cutter discs. The large cutter discs are arranged by rotating them sequentially from both ends of the mounting shaft toward the middle at a fixed angle, and the small cutter discs are arranged by rotating them sequentially from both ends of the mounting shaft toward the middle at a fixed angle.

[0013] Preferably, the large cutter disc includes a main disc and main cutting teeth, the main cutting teeth are fixedly installed on the outer surface of the main disc, and three main cutting teeth are evenly arranged. The small cutter disc includes a secondary disc and secondary cutting teeth, the secondary cutting teeth are fixedly installed on the outer surface of the secondary disc, and three secondary cutting teeth are evenly arranged.

[0014] Preferably, the main cutting tooth is provided with a main transition fillet and a main end face, and the secondary cutting tooth is provided with a secondary transition fillet and a secondary end face. The radial lengths of the main cutting tooth and the secondary cutting tooth are consistent. The secondary end face is aligned with the main transition fillet, and there is a gap between the two sides of the secondary cutting tooth and the main disk.

[0015] The beneficial effects of this invention are: In this invention, by setting an inclined feeding plate with guide strips and fixed blades in the upper housing, and combining it with the coordinated clamping and conveying of fixed rollers and floating rollers, automatic centering, adaptive clamping, and continuous and stable feeding of lead plates are achieved, improving the automation level and feeding reliability of the device, and avoiding the inefficiency and safety hazards caused by manual operation. Simultaneously, by utilizing the meshing transmission of the first and second gears in the moving components, and the linkage structure of the steel chain with the driving and driven wheels, the fixed rollers and floating rollers can be driven synchronously by the same power source. This not only ensures the synchronicity and stability of the feeding process, but also, through the setting of the floating components, allows the floating rollers to automatically adjust the clamping gap and maintain a constant clamping force according to the changes in lead plate thickness, thereby adapting to the feeding requirements of lead plates of different thicknesses and expanding the applicability of the device. Based on this, the crushing mechanism uses a large cutter head and a small cutter head arranged at a fixed angle, rotating sequentially from both ends of the mounting shaft towards the middle, so that each cutter head... The main and secondary cutting teeth are staggered along the axial direction, cutting into the material sequentially from both ends to the middle during rotary shearing. Compared with the traditional method of simultaneous cutting, this reduces instantaneous shearing resistance and peak torque, avoids overload of the drive motor and jamming of the cutter head, and provides more ample discharge clearance for each cutting tooth during time-sharing cutting, effectively reducing the adhesion and accumulation of soft lead material on the cutting tooth surface. Combined with the structural design of precise alignment between the secondary end face and the main transition fillet, it achieves graded shearing of lead plates, ensuring that the material is thoroughly cut in both width and length directions to form uniform fragments, improving crushing quality and particle size consistency. Furthermore, the fragments can be smoothly discharged from the bottom of the lower box under gravity without the need for additional auxiliary discharge devices, simplifying the equipment structure and reducing manufacturing costs and maintenance difficulty. The invention has a reasonable structural design, stable and reliable operation, and is suitable for large-scale automated crushing of electrolytic lead plates, showing good prospects for industrial application.

Detailed Implementation

[0028] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] Reference Figures 1 to 2 The present invention provides an electrolytic lead plate crushing device with automatic feeding function, including a lower box 1, an upper box 2 fixedly installed on the top of the lower box 1, a feeding mechanism 3 provided in the upper box 2, and a crushing mechanism 4 provided in the lower box 1. The feeding mechanism 3 is used to automatically center and press the electrolytic lead plate to the crushing mechanism 4, and the crushing mechanism 4 is used to cut and crush the electrolytic lead plate into uniform fragments in stages.

[0030] Reference Figures 1 to 6 The feeding mechanism 3 includes a feeding plate 31, a rotating rod 32, a rotating rod 33, and a movable component 37. The feeding plate 31 is arranged at an angle and is fixedly installed inside the upper housing 2. Guide bars 312 are fixedly installed on the feeding plate 31, and two guide bars 312 are symmetrically arranged. A fixed blade 36 is fixedly installed at the bottom of the feeding plate 31, and the fixed blade 36 is provided with clearance openings 361, and multiple clearance openings 361 are evenly arranged. This angled arrangement and the cooperation of the guide bars 312 can realize the self-weight guidance of the lead plate, while the clearance openings 361 on the fixed blade 36 provide precise shearing space for subsequent crushing, which is conducive to continuous and stable feeding.

[0031] The guide bar 312 is provided with a parallel section 3121 and an inclined section 3122. The spacing of the inclined sections 3122 decreases along the movement direction of the lead plate. The feed plate 31 is also provided with a through-hole 311. The inclined sections 3122 enable the lead plate to automatically center itself during the downward movement, effectively preventing deviation. The through-hole 311 provides a clearance position for the installation of the fixed roller 34.

[0032] The rotating rod 32 is rotatably mounted on the upper housing 2. A fixed roller 34 is fixedly mounted on the surface of the rotating rod 32, and the fixed roller 34 is located inside the through-hole 311. There are two rotating rods 33, and a floating roller 35 is fixedly mounted on the surface of the rotating rod 33. The rotating rod 32 is coaxially and fixedly connected to the power equipment used to pull the rotating rod 32 to rotate around its own axis. The fixed roller 34 and the floating roller 35 form a clamping and conveying pair, and are driven by the same power source to ensure synchronous rotation, which is conducive to achieving uniform and stable automatic feeding.

[0033] Preferably, the surface of the fixed roller 34 is covered with rubber to increase friction during feeding; the surface of the floating roller 35 is grooved to adapt to the rough surface of the lead.

[0034] Each of the left and right sides of the upper housing 2 has a movable component 37. Each movable component 37 includes a positioning shaft 371, a first gear 372, a second gear 373, a support frame 375, a steel chain 377, and a floating component 378. The positioning shaft 371 is rotatably mounted on the upper housing 2, and the support frame 375 is fixedly mounted on the upper housing 2. A tensioning wheel 376 is rotatably mounted on the support frame 375. The first gear 372 is fixedly mounted on the surface of the rotating rod 32, and the second gear 373 is fixedly mounted on the surface of the positioning shaft 371. The first gear 372 and the second gear 373 are meshed together. A drive wheel 374 is also fixedly mounted on the surface of the positioning shaft 371. Through the meshing transmission of the first gear 372 and the second gear 373, power is reliably transmitted to the drive wheel 374. This, combined with the tensioning wheel 376, ensures the tension of the steel chain 377, achieving efficient and stable power distribution and ensuring synchronous operation of multiple rollers.

[0035] Floating components 378 are disposed at both ends of the rotating rod 33. There are four floating components 378. Each floating component 378 includes a fixed frame 3781, a moving plate 3784, and a driven wheel 3785. The fixed frame 3781 is fixedly installed on the upper housing 2. A strip hole 3782 is opened on the fixed frame 3781. A guide rod 3783 is fixedly installed in the strip hole 3782. The moving plate 3784 is sleeved on the surface of the guide rod 3783. A compression spring 3786 is sleeved on the surface of the guide rod 3783. The rotating rod 33 is rotatably mounted on the moving plate 3784, and the driven wheel 3785 is fixedly installed at the end of the rotating rod 33. The steel chain 377 is located between the driving wheel 374 and the two driven wheels 3785. The floating component 378 allows the moving plate 3784 to slide along the strip hole 3782 via the compression spring 3786 and the guide rod 3783, thereby driving the floating roller 35 to adapt to lead plates of different thicknesses and maintain a constant clamping force, effectively preventing slippage or jamming, and improving feeding reliability and applicability.

[0036] In use, the lead plate enters the upper housing 2 through the inclined feed plate 31. Two guide strips 312 on the feed plate 31 guide the lead plate. The spacing of the inclined sections 3122 decreases along the direction of movement of the lead plate, so that the lead plate automatically centers itself as it slides down the feed plate 31 under its own weight. Subsequently, the lead plate reaches the insertion opening 311, where the fixed roller 34, which is fixedly mounted on the surface of the rotating rod 32, is located inside the insertion opening 311. The rotating rod 32 is driven to rotate by a power device. The rotation of the rotating rod 32 drives the fixed roller 34 to rotate synchronously around the axis of the rotating rod 32. At the same time, the rotating rod 32 drives the positioning shaft 371 and the driving wheel 374 fixed on its surface to rotate synchronously through the first gear 372 and the second gear 373. The driving wheel 374 transmits power to two driven wheels 3785 through the steel chain 377. The driven wheels 3785 rotate and drive the two rotating rods 33 and the floating roller. 35 rotates synchronously, and tensioning wheel 376 tensions steel chain 377 to ensure the stability of power transmission. Floating roller 35 achieves thickness self-adaptation through floating components 378 set at both ends. Specifically, when the lead plate passes through floating roller 35, the floating roller 35 is squeezed and can automatically adjust the clamping gap according to the lead plate of different thicknesses. At the same time, moving plate 3784 slides along guide rod 3783. Compression spring 3786 is squeezed and contracts, applying elastic force to moving plate 3784. This elastic force acts on floating roller 35, so that floating roller 35 can maintain sufficient clamping force on lead plate to ensure continuous feeding. Under the clamping and conveying of fixed roller 34 and floating roller 35, lead plate continues to descend and reaches fixed blade 36 fixedly installed at the bottom of feed plate 31. Multiple clearance openings 361 evenly set on fixed blade 36 provide shearing space for subsequent crushing mechanism 4.

[0037] In summary, by setting an inclined feed plate 31 inside the upper housing 2, and combining it with the structural design where the spacing of the inclined sections 3122 on the guide strip 312 decreases along the direction of the lead plate's movement, the lead plate can automatically center itself as it slides down the feed plate 31 under its own weight, ensuring the continuity and positional accuracy of subsequent feeding. Simultaneously, the fixed roller 34 on the rotating rod 32 and the floating rollers 35 on the two rotating rods 33 work together to clamp the lead plate. Furthermore, through the meshing transmission of the first gear 372 and the second gear 373 in the movable assembly 37, and the linkage structure where the driving wheel 374 on the positioning shaft 371 synchronously drives the two driven wheels 3785 via the steel chain 377, the fixed roller 34 and the two floating rollers 35 are driven synchronously by the same power source, ensuring both the synchronization and stability of the feeding process, simplifying the transmission structure, and reducing equipment costs. Furthermore, in the floating component 378, the moving plate 3784 is sleeved on the surface of the guide rod 3783, and under the elastic action of the compression spring 3786, the floating roller 35 can automatically adjust the clamping gap according to the different thicknesses of the lead plate and maintain sufficient constant clamping force. This adaptive floating clamping structure not only avoids jamming or slippage caused by uneven lead plate thickness, but also ensures stable clamping and conveying of lead plates of different thicknesses, expanding the applicability of the device. In addition, the tensioning wheel 376 is rotatably mounted on the support frame 375 and tensions the steel chain 377, ensuring continuous and reliable power transmission. Finally, the lead plate is continuously and smoothly fed to the fixed blade 36 under the clamping and conveying of the fixed roller 34 and the floating roller 35. The multiple clearance openings 361 evenly arranged on the fixed blade 36 provide precise shearing space for the subsequent crushing mechanism 4.

[0038] Reference Figures 1 to 10 The crushing mechanism 4 includes a mounting shaft 41, which is rotatably mounted on the lower housing 1. The mounting shaft 41 is coaxially and fixedly connected to a power device for traction, which rotates the mounting shaft 41 around its own axis. Large cutter discs 42 and small cutter discs 43 are fixedly mounted on the surface of the mounting shaft 41. Multiple large cutter discs 42 are evenly distributed, and the small cutter discs 43 are evenly distributed within the intervals between the large cutter discs 42. The large cutter discs 42 are arranged by rotating sequentially from both ends of the mounting shaft 41 towards the center at fixed angles, and the small cutter discs 43 are also arranged by rotating sequentially from both ends of the mounting shaft 41 towards the center at fixed angles. This staggered arrangement structure allows each cutter disc to cut into the material sequentially and at different times along the axial direction, effectively reducing instantaneous shearing resistance and peak torque, and preventing overload of the drive motor and cutter disc jamming.

[0039] The large cutter head 42 includes a main disc 421 and main cutter teeth 422. The main cutter teeth 422 are fixedly installed on the outer surface of the main disc 421, and three main cutter teeth 422 are evenly arranged. The small cutter head 43 includes a secondary disc 431 and secondary cutter teeth 432. The secondary cutter teeth 432 are fixedly installed on the outer surface of the secondary disc 431, and three secondary cutter teeth 432 are evenly arranged. The main cutter teeth 422 are provided with a main transition fillet 4221 and a main end face 4222. The secondary cutter teeth 432 are provided with a secondary transition fillet 4321 and a secondary end face 4322. The radial lengths of the main cutter teeth 422 and the secondary cutter teeth 432 are consistent. The secondary end face 4322 is aligned with the main transition fillet 4221. There is a gap between the two sides of the secondary cutter teeth 432 and the main disc 421. The radial lengths of the main cutter tooth 422 and the secondary cutter tooth 432 are consistent to ensure uniform shearing depth. The secondary end face 4322 is aligned with the main transition fillet 4221 to achieve graded shearing and ensure uniform fragments. The gaps between the two sides of the secondary cutter tooth 432 and the main disc 421 facilitate material insertion and fragment discharge, effectively preventing sticking and clogging.

[0040] In use, the mounting shaft 41 of the crushing mechanism 4 is driven to rotate by a power device. The radial lengths of the main cutter teeth 422 and the secondary cutter teeth 432 are kept consistent to ensure the same shearing depth. When the mounting shaft 41 rotates, the main cutter teeth 422 of the large cutter disc 42 first rotate to the clearance opening 361 of the fixed cutter 36, and cooperate with the fixed cutter 36 to perform the initial shearing of the lead plate, cutting the continuous lead plate into several convex materials with a width corresponding to the spacing of the main cutter teeth 422. Subsequently, the secondary cutter teeth 432 of the small cutter disc 43 rotate. Since the secondary end face 4322 is aligned with the main transition fillet 4221, the convex materials are precisely cut off, so that each piece of material is completely separated in both width and length directions, forming uniform fragments. There are gaps between the two sides of the secondary cutter teeth 432 and the main disc 421, which facilitates the insertion of convex materials and the sliding out of the fragments after being cut by the small cutter disc 43. During this process, the large cutter disc 4... The two ends of the mounting shaft 41 are rotated sequentially towards the middle at a fixed angle. Similarly, the small cutter discs 43 are also rotated sequentially towards the middle from both ends of the mounting shaft 41 at a fixed angle. This arrangement ensures that when the cutter discs distributed along the axial direction of the mounting shaft 41 rotate, their teeth do not cut into the material simultaneously, but rather in sequence from both ends towards the middle. This staggered arrangement effectively reduces the number of main cutter teeth 422 and auxiliary cutter teeth 432 participating in shearing at the same time, reduces instantaneous shearing resistance, and avoids jamming or overload of the drive motor due to excessive instantaneous load. At the same time, time-sharing shearing also allows each cutter tooth more sufficient discharge time, preventing soft lead material from sticking and clogging between the cutter teeth. After shearing, the lead plate is broken into small, uniformly sized pieces. Under the action of gravity, the pieces are discharged from the bottom of the lower box 1 to the subsequent belt conveyor, completing the entire automatic feeding and crushing process.

[0041] In summary, both the large cutter head 42 and the small cutter head 43 are arranged by rotating sequentially from both ends of the mounting shaft 41 towards the middle at a fixed angle. This ensures that when the cutter heads distributed along the axial direction of the mounting shaft 41 rotate, their main cutter teeth 422 and auxiliary cutter teeth 432 do not cut into the material simultaneously, but rather sequentially from both ends towards the middle. This staggered arrangement effectively reduces the number of main cutter teeth 422 and auxiliary cutter teeth 432 participating in shearing at the same time, reducing instantaneous shearing resistance and peak torque. This avoids problems such as drive motor overload or cutter head jamming caused by excessive instantaneous load, improving the stability and reliability of equipment operation. At the same time, because each cutter tooth cuts into the material at different times, each cutter tooth obtains more sufficient discharge gap and time after completing shearing, effectively preventing soft lead material from sticking to the cutter tooth surface and causing blade clogging. This design ensures a smooth and continuous shearing process and reduces downtime for cleaning. Furthermore, the consistent radial length of the main cutter teeth 422 and the secondary cutter teeth 432 ensures uniform shearing depth. The precise alignment of the secondary end face 4322 with the main transition fillet 4221 allows the main cutter teeth 422 of the large cutter disc 42 to first cooperate with the fixed cutter 36 to cut the continuous lead plate into several convex materials. Then, the secondary cutter teeth 432 of the small cutter disc 43 perform a second, precise cut on the convex materials, achieving a step-by-step, graded shearing of the lead plate. This ensures that each piece of material is thoroughly separated in both width and length, ultimately forming uniformly sized fragments. Additionally, the gap between the secondary cutter teeth 432 and the main disc 421 facilitates the smooth insertion of convex materials into the shearing area and allows the fragments to slide out smoothly after cutting, preventing material accumulation and poor discharge.

[0042] The working principle of this invention: The lead plate enters the upper housing 2 through the inclined feed plate 31. Two guide strips 312 on the feed plate 31 guide the lead plate. The spacing of the inclined sections 3122 decreases along the direction of movement of the lead plate, allowing the lead plate to automatically center itself as it slides down the feed plate 31 under its own weight. Subsequently, the lead plate reaches the insertion opening 311. A fixed roller 34, fixedly mounted on the surface of the rotating rod 32, is located within the insertion opening 311. The rotating rod 32 is driven to rotate by a power device. The rotation of the rotating rod 32 drives the fixed roller 34 to rotate synchronously around the axis of the rotating rod 32. Simultaneously, the rotating rod 32 drives the positioning shaft 371 and the driving wheel 374 fixed on its surface to rotate synchronously through the first gear 372 and the second gear 373. The driving wheel 374 transmits power to two driven wheels 3785 through a steel chain 377. The driven wheels 3785 rotate and drive the two rotating rods 33 and... The floating roller 35 rotates synchronously, and the tensioning wheel 376 tensions the steel chain 377 to ensure the stability of power transmission. The floating roller 35 achieves thickness self-adaptation through the floating components 378 set at both ends. Specifically, when the lead plate passes through the floating roller 35, the floating roller 35 can automatically adjust the clamping gap according to the lead plate of different thicknesses after being squeezed. At the same time, the moving plate 3784 slides along the guide rod 3783. The compression spring 3786 contracts after being squeezed and applies an elastic force to the moving plate 3784. This elastic force acts on the floating roller 35, so that the floating roller 35 can maintain sufficient clamping force on the lead plate to ensure the continuity of feeding. The lead plate continues to descend under the clamping and conveying of the fixed roller 34 and the floating roller 35, and reaches the fixed blade 36 fixedly installed at the bottom of the feed plate 31. Multiple clearance openings 361 evenly set on the fixed blade 36 provide shearing space for the subsequent large blade disc 42.

[0043] Meanwhile, the mounting shaft 41 of the crushing mechanism 4 is driven to rotate by a power device. The radial lengths of the main cutter teeth 422 and the secondary cutter teeth 432 are kept consistent to ensure the same shearing depth. When the mounting shaft 41 rotates, the main cutter teeth 422 of the large cutter disc 42 first rotate to the clearance opening 361 of the fixed cutter 36, and cooperate with the fixed cutter 36 to perform the initial shearing of the lead plate, cutting the continuous lead plate into several convex materials with a width corresponding to the spacing of the main cutter teeth 422. Subsequently, the secondary cutter teeth 432 of the small cutter disc 43 rotate. Since the secondary end face 4322 is aligned with the main transition fillet 4221, the convex materials are precisely cut off, so that each piece of material is completely separated in both width and length directions, forming uniform fragments. There are gaps between the two sides of the secondary cutter teeth 432 and the main disc 421, which facilitates the insertion of convex materials and the sliding out of the fragments after being cut by the small cutter disc 43. During this process, the large cutter disc... The main cutter teeth 422 and the auxiliary cutter teeth 432 are arranged by rotating sequentially from both ends of the mounting shaft 41 toward the middle at a fixed angle. This arrangement ensures that the cutter teeth of each cutter head distributed along the axial direction of the mounting shaft 41 do not cut into the material simultaneously, but rather in sequence from both ends toward the middle. This staggered arrangement effectively reduces the number of main cutter teeth 422 and auxiliary cutter teeth 432 participating in shearing at the same time, reduces instantaneous shearing resistance, and avoids jamming or overload of the drive motor due to excessive instantaneous load. At the same time, the time-sharing shearing also allows each cutter tooth more time to discharge material, preventing soft lead material from sticking and clogging between the cutter teeth. After shearing, the lead plate is broken into small pieces of uniform size. The pieces are discharged from the bottom of the lower box 1 to the subsequent belt conveyor under the action of gravity, completing the entire automatic feeding and crushing process.
