Description

Technical Field

[0001] The invention belongs to the technical field of anode carbon block slotting equipment, and in particular relates to a continuous electrolytic aluminum anode carbon block slotting machine. Background Art

[0002] The uneven density of electrolytic aluminum anode carbon blocks is caused by the multi-link coupling effect of the manufacturing process, for example, raw material mixing defects: petroleum coke particles and liquid asphalt are prone to form "coke balls" and "asphalt-rich areas" during the kneading process, resulting in excessive local binder and the formation of densified nodes; molding pressure fluctuations: the pressure field is unevenly distributed during the vibration molding stage, resulting in the core density of the carbon block being significantly higher than the surface layer; roasting shrinkage differences: when the carbon block is roasted, the difference in the escape rate of volatiles causes anisotropic shrinkage, forming an internal residual stress concentration zone; graphitization gradient: in the high temperature zone (>1100℃), the carbon structure is not completely transformed into a graphite state, resulting in a hard microcrystalline area, etc.

[0003] In the electrolytic aluminum production process, the slotting of anode carbon blocks is one of the key steps. The traditional anode carbon block slotting machine performs continuous slotting operations by pushing multiple carbon blocks through the cutting main machine in sequence. However, in actual operation, due to the uneven density of the anode carbon block material, the density in some areas is high, resulting in a significant increase in cutting resistance.

[0004] When the cutting saw blade encounters a high-density area, the cutting resistance will increase significantly. If the moving speed of the carbon block remains unchanged at this time, the saw blade will be subjected to excessive extrusion pressure. Working in this state for a long time will cause the saw blade to wear more. As the saw blade wears, its edge gradually becomes blunt, and the cutting efficiency is significantly reduced. In severe cases, there is a risk of the saw blade breaking due to excessive load, resulting in serious consequences such as damage to the slotting host and interruption of production. Based on this, we propose a continuous electrolytic aluminum anode carbon block slotting machine. Summary of the invention

[0005] The purpose of the present invention is to provide a continuous electrolytic aluminum anode carbon block slotting machine, aiming to solve the technical problem of a sudden increase in cutting resistance when a saw blade passes through a high-density area during the slotting process of the electrolytic aluminum anode carbon block.

[0006] A continuous electrolytic aluminum anode carbon block slotting machine comprises a workbench, the workbench is provided with a conveying unit, a slotting main machine and a charging frame, the slotting main machine has a saw blade, the saw blade is used to slot the electrolytic aluminum anode carbon block, the charging frame has a clamping mechanism, the clamping mechanism is used to clamp and fix the electrolytic aluminum anode carbon block, the workbench is provided with a movable frame slidably connected with the movable frame, the movable frame is slidably connected with the charging frame, the movable frame is used to drive the electrolytic aluminum anode carbon block to move and slot through the charging frame, the top of the movable frame is located on both sides of the charging frame and fixed plates are respectively provided, the fixed plates on both sides are symmetrically arranged with limit members, and multiple groups of limit members are arranged at intervals on one side of the fixed plate, the limit member is vertically slidably penetrated through the fixed plate, one end of the limit member is provided with a V-shaped surface, and the other end is provided with a baffle, a first spring is provided between the baffle and the fixed plate, the V-shaped surfaces of the limit members on both sides are arranged oppositely, and the V-shaped surfaces are in contact with the charging frame to limit the charging frame.

[0007] When the saw blade is rotated to cut grooves to the high-density area of ​​the electrolytic aluminum anode carbon block, the limit parts abutting against the loading frame provide it with a certain limit force. When the cutting resistance is greater than the limit force, the loading frame squeezes this group of limit parts to its two sides and moves to the next group of limit parts. The cutting resistance is reduced, avoiding a sudden and substantial increase in the cutting resistance, thereby reducing the risk of the saw blade being damaged due to excessive cutting resistance.

[0008] Furthermore, in the direction away from the movable frame, the elastic coefficient of the first spring gradually increases, slide rails are provided on both sides of the grooving main unit, the movable frame is slidably connected to the slide rails, an n-shaped baffle is provided at one end of the slide rail, and the n-shaped baffle is used to limit the loading frame.

[0009] The limiter provides a step-by-step limit force for the loading frame, which reduces the risk of damage to the saw blade. At the same time, the gradually increasing limit force helps to rotate the saw blade to cut the high-density area of ​​the electrolytic aluminum anode carbon block.

[0010] Furthermore, a buffer tank is provided on the top of the movable frame, and liquid medium is filled in the buffer tank. A fixed rod is passed through the buffer tank and is sealingly and slidably connected to the buffer tank. One end of the fixed rod is connected to the loading frame. The sliding direction of the fixed rod is consistent with the loading frame. The fixed rod located in the buffer tank is sleeved with a first buffer plate. The edge of the first buffer plate is sealingly and slidably connected to the inner wall of the buffer tank, and the first buffer plate is provided with a first through hole.

[0011] When the loading frame moves, the fixed rod drives the first buffer plate to move in the buffer tank, and the liquid medium flows from one side of the first buffer plate to the other side through the first through hole. The resistance generated by the flow is transmitted to the electrolytic aluminum anode carbon block, buffering the movement of the loading frame and contributing to the smooth transition of the cutting resistance.

[0012] The cam is an adjustable speed gear, and the adjustable speed gear is connected to the upper and lower frames by the spring, and the adjustable speed gear is connected to the upper and lower frames by the spring.

[0013] The one-way limit rack and the limit block cooperate with the limit fixing rod to help reduce the violent fluctuations generated during the cutting of the electrolytic aluminum anode carbon block by the rotating saw blade, so that the rotating saw blade maintains a relatively stable cutting force on the electrolytic aluminum anode carbon block.

[0014] Furthermore, the fixed rod in the buffer tank is provided with a limiting flange and a second buffer plate, the second buffer plate is located between the first buffer plate and the limiting flange, the second buffer plate is sealingly and slidingly connected to the fixed rod, and the edge of the second buffer plate is sealingly and slidingly matched with the inner wall of the buffer tank, the second buffer plate is provided with a second through hole, the number of the second through holes is the same as that of the first through holes and they are aligned, and the aperture of the second through hole is smaller than the aperture of the first through hole.

[0015] When the first buffer plate drives the second buffer plate to move, the liquid medium flows through the second through hole and the first through hole. Compared with the liquid medium only flowing through the first through hole, the flow area is reduced and the flow resistance is increased, that is, the cutting resistance of the rotating saw blade is slowly increased.

[0016] Furthermore, a limiting slip ring is slidably sleeved on the fixed rod located in the buffer tank, a second spring is provided between the limiting slip ring and the second buffer plate, the limiting slip ring is spaced from the inner wall of the buffer tank, a slide groove is relatively provided on the inner wall of the buffer tank, the slide groove is located in the buffer tank close to the loading frame, the limiting plate is slidably connected in the slide groove, the limiting plate slides radially along the buffer tank, a third spring is provided between the limiting plate and the bottom surface of the slide groove, adjacent edges of the limiting plates on both sides are symmetrically provided with inclined limiting surfaces, the inclined limiting surfaces on the limiting plates form a wave-like structure, and the limiting plates on both sides cooperate with the limiting slip rings.

[0017] The limit plate forms multiple "peaks" and "troughs". In the process of the limit slip ring squeezing and passing through the "peak" of the limit plate into the "trough", the cutting resistance borne by the saw blade gradually increases and then decreases. The second spring restores the elastic potential energy, and the limit slip ring squeezes the next peak again. The cutting resistance borne by the saw blade gradually increases again. This is repeated, which helps to cut the electrolytic aluminum anode carbon block while protecting the saw blade.

[0018] Furthermore, the limiting force generated by all the third springs in the slide grooves on both sides acting on the limiting plate is equal to the elastic force generated by half the deformation of the second spring.

[0019] The present invention has the following beneficial effects.

[0020] 1. In the present invention, a sliding cooperation between the movable frame and the loading frame is arranged, and a plurality of groups of limit members are evenly spaced on the fixed plates on both sides of the loading frame. The first spring on the limit member cooperates with the V-shaped surface to limit the loading frame, so as to provide a certain limit force for the loading frame. When the cutting resistance of the saw blade is greater than the limit force of a group of limit members, the loading frame squeezes the group of limit members to its two sides and moves to the next group of limit members. The elastic coefficient of the first spring gradually increases in the direction away from the loading frame, so that the cutting resistance increases in a step-by-step manner, which can effectively reduce the risk of damage to the saw blade due to a sudden and substantial increase in the cutting resistance.

[0021] 2. In the present invention, a buffer tank is arranged on the movable frame, and the first buffer plate is driven to move by the fixed rod, and the liquid medium flows through the first through hole to generate resistance to buffer the drastic change of the cutting force; the first buffer plate drives the second buffer plate to move, and the liquid medium flows through the second through hole and the first through hole. As the flow area of ​​the liquid medium decreases, the resistance gradually increases, and the corresponding cutting resistance borne by the saw blade gradually increases; the fixed rod continuously squeezes the second spring through the first buffer plate and the second buffer plate, and the corresponding limit slip ring continuously squeezes the limit plate, and the limit slip ring passes through the first group of "peaks" on the limit plate and enters the first group of troughs, the elastic potential energy of the second spring is restored, and the cutting force gradually increases and then decreases, and this is repeated. While protecting the saw blade, it helps the saw blade to cut the high-density area of ​​the electrolytic aluminum anode carbon block. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0030] Example 1 Reference Figure 1 The present embodiment discloses a continuous electrolytic aluminum anode carbon block slotting machine, which is used for continuously slotting the electrolytic aluminum anode carbon block 400.

[0031] According to an embodiment of the present application, a continuous electrolytic aluminum anode carbon block slotting machine includes a workbench, and a movable frame 200 and a charging frame 300 arranged on the workbench.

[0032] The specific structure and connection relationship of each component are as follows: 1. Workbench Reference Figure 1 The workbench is provided with a slotting main machine 100 and a conveying unit. The slotting main machine 100 has two saw blades 101. Conveying units are respectively provided on both sides of the slotting main machine 100 along the conveying direction of the electrolytic aluminum anode carbon block; slide rails 201 are arranged in parallel on the other two sides of the slotting main machine 100, and an n-shaped baffle plate 202 is arranged on one end of the slide rail 201 at which the electrolytic aluminum anode carbon block to be slotted is Figure 2 ).

[0033] The above arrangement can realize that the anode carbon block to be grooved is transported to one side of the groove cutting main machine 100 via the conveying unit, and the groove cutting main machine 100 uses the saw blade 101 to groove the electrolytic aluminum anode carbon block 400, and the grooved electrolytic aluminum anode carbon block is transported to the subsequent process via the conveying unit.

[0034] 2. Mobile rack 200 and loading frame 300 Reference Figure 1 The movable frame 200 is slidably connected to the slide rails 201 on both sides (refer to Figure 2 ) The loading frame 300 is slidably disposed on the moving frame 200, and a clamping mechanism is provided inside the loading frame 300. The upper portion of the loading frame 300 extends outward to the top outer side of the moving frame 200. (Refer to Figure 3 ) A fixing plate 210 is provided on the top of the moving frame 200, and the fixing plate 210 is arranged on both sides of the loading frame 300, and the fixing plate 210 extends to the outside of the moving frame 200 along the moving direction of the moving frame 200, and the fixing plates 210 on both sides are symmetrically provided with limit members 211.

[0035] Reference Figure 3 Taking the fixed plate 210 on one side as an example, a plurality of limit members 211 are evenly spaced along the length direction of the fixed plate 210, the limit members 211 are arranged in the horizontal direction, the limit members 211 are vertically and slidably penetrated through the fixed plate 210, a V-shaped surface 212 is provided at one end of the limit member 211, and a baffle is provided at the other end, a first spring 213 is provided between the baffle and the fixed plate 210, and the V-shaped surfaces 212 of the limit members 211 on the fixed plates 210 on both sides are arranged relatively.

[0036] Preferably, three groups of limiters 211 are arranged at intervals on the fixed plate 210. The first group of limiters 211, the second group of limiters 211 and the third group of limiters 211 are arranged at intervals in sequence in the direction away from the movable frame 200. The elastic coefficient of the first spring 213 on the limiter 211 gradually increases.

[0037] The moving frame 200 has a driving system, which is used to drive the moving frame 200 to reciprocate along the slide rail 201. Detection units 301 are respectively provided on both sides of the moving direction of the loading frame 300, and the detection units 301 control the moving speed of the moving frame 200 by detecting the distance between the anode carbon block 400 to be electrolyzed aluminum and the slot cutting main machine 100. The detection unit 301 is an image recognition sensor.

[0038] The electrolytic aluminum anode carbon block slotting machine of the present invention has a control panel, which is electrically connected to all electrical components in the slotting machine. The control panel, the conveying unit, the slotting main machine 100, the clamping mechanism and the driving system are all existing mechanisms.

[0039] The above arrangement can be realized, the movable frame 200 can drive the loading frame 300 to move back and forth along the slide rail 201, the loading frame 300 stably clamps the electrolytic aluminum anode carbon block 400 through the clamping mechanism, the loading frame 300 slides with the movable frame 200, the loading frame 300 contacts the V-shaped surface 212 of the limiting member 211, and a group of limiting members 211 are used to limit the loading frame 300, and the limiting members 211 located on one side of the loading frame 300 from near to far can provide it with a gradually increasing limiting force.

[0040] The working process of the continuous electrolytic aluminum anode carbon block slotting machine in this embodiment is as follows: First, the control panel controls the conveying unit to convey the electrolytic aluminum anode carbon block 400 to be slotted into the loading frame 300, and the conveying unit stops working. The clamping mechanism of the loading frame 300 stably clamps the electrolytic aluminum anode carbon block 400. At the same time, the grooving host 100 drives the saw blade 101 to rotate, and the movable frame 200 and the loading frame 300 are both in the initial position. The loading frame 300 contacts the n-shaped baffle 202, and the loading frame 300 contacts the adjacent first group of limit members 211.

[0041] Then, the moving frame 200 drives the loading frame 300 to move along one end of the slide rail 201 to the other end. At this time, the first group of limit members 211 limits the loading frame 300. During the movement, the loading frame 300 and the moving frame 200 remain relatively still. When the detection unit 301 on one side detects that the electrolytic aluminum anode carbon block 400 moves close to the saw blade 101, the driving system of the moving frame 200 controls the moving frame 200 to drive the loading frame 300 to move slowly. The two rotating saw blades 101 groove the electrolytic aluminum anode carbon block 400, which helps to ensure the regularity of the grooves on the electrolytic aluminum anode carbon block 400. When the detection unit 301 on the other side detects that the rotating saw blade 101 is close to the end of the electrolytic aluminum anode carbon block 400, the driving system of the moving frame 200 controls the moving frame 200 to drive the loading frame 300 to keep cutting grooves slowly, thereby ensuring the quality of the cutting grooves.

[0042] Subsequently, the movable rack 200 drives the electrolytic aluminum anode carbon block 400 after the groove cutting to the end of the slide rail 201 through the loading frame 300, and the electrolytic aluminum anode carbon block 400 moves to the conveying unit, the clamping mechanism separates from the electrolytic aluminum anode carbon block 400, and the conveying unit conveys the electrolytic aluminum anode carbon block 400 after the groove cutting to the next process.

[0043] Finally, the driving system of the moving frame 200 controls the moving frame 200 to move in the reverse direction, and the loading frame 300 moves to abut against the n-shaped baffle 202, forcing the loading frame 300 and the moving frame 200 to return to the initial position.

[0044] During the grooving process of the electrolytic aluminum anode carbon block 400 by the grooving main machine 100, under normal conditions, the sum of the cutting resistances between the two rotating saw blades 101 and the electrolytic aluminum anode carbon block 400 is less than the sum of the limiting forces generated by the first springs 213 on a set of limiting members 211 abutting against the loading frame 300. The cutting resistance of the saw blade 101 to the electrolytic aluminum anode carbon block 400 remains relatively stable, and the movable frame 200 and the loading frame 300 remain relatively still, so that the electrolytic aluminum anode carbon block 400 can be grooved.

[0045] When the grooving main machine 100 is grooving the electrolytic aluminum anode carbon block 400, when the rotating saw blade 101 passes through the high-density area in the electrolytic aluminum anode carbon block 400, the cutting resistance between the electrolytic aluminum anode carbon block 400 and the rotating saw blade 101 increases significantly. When the sum of the cutting resistances is greater than the sum of the limiting forces of the two limiting members 211 on the loading frame 300, the movable frame 200 continues to move forward (i.e., moves toward the conveying end of the electrolytic aluminum anode carbon block 400), and the electrolytic aluminum anode carbon block 400 first remains relatively still (at this time, the rotating saw blade 101 slowly cuts the electrolytic aluminum anode carbon block 400), and the electrolytic aluminum anode carbon block 400 forces the loading frame 300 to move backward relative to the movable frame 200 (i.e., moves toward the conveying front end of the electrolytic aluminum anode carbon block 400) through the clamping mechanism. At this time, the loading frame 300 continues to squeeze the V-shaped surface 212 of the first group of limiting members 211 abutting against it, so that the first group of limiting members 211 moves away from the loading frame 300 and compresses the first spring 213 on the first group of limiting members 211.

[0046] The loading frame 300 moves to the adjacent second group of stoppers 211 and contacts the V-shaped surface 212 of the second group of stoppers 211. Since the elastic coefficient of the first spring 213 on the stoppers 211 farther from the moving frame 200 is greater, the stop force provided by the second group of stoppers 211 contacting the loading frame 300 is greater than the stop force provided by the first group of stoppers 211, thereby ensuring a greater cutting force between the electrolytic aluminum anode carbon block 400 and the rotating saw blade 101. If the rotating saw blade 101 still does not pass through the high-density area of ​​the electrolytic aluminum anode carbon block 400, the loading frame 300 squeezes the second group of stoppers 211 to compress the first spring 213 thereon, and then the loading frame 300 moves to contact the third group of stoppers 211.

[0047] After the movable rack 200 drives the electrolytic aluminum anode carbon block 400 to complete the slotting through the loading frame 300, the movable rack 200 drives the loading frame 300 to move in the opposite direction to the initial position, and the loading frame 300 contacts the n-shaped baffle plate 202. Under the blocking and limiting action of the n-shaped baffle plate 202, the movable rack 200 continues to reset and move, so that the loading frame 300 returns to the initial position on the movable rack 200, that is, the loading frame 300 moves to the side of the first group of limiting members 211 closest to the movable rack 200.

[0048] By increasing the limiting force on the electrolytic aluminum anode carbon block 400 in multiple stages, the cutting force on the electrolytic aluminum anode carbon block 400 can be increased in multiple stages. The relative movement between the movable frame 200 and the loading frame 300 can prevent the rotating saw blade 101 from being subjected to a sudden and substantial increase in cutting resistance, thereby reducing the occurrence of breakage and damage of the rotating saw blade 101, and helping to ensure the continuous operation of the electrolytic aluminum anode carbon block grooving machine.

[0049] Example 2 The present embodiment discloses a continuous aluminum electrolytic anode carbon block slotting machine. Based on the first embodiment, the loading frame 300 has the function of buffering the cutting resistance between the saw blade 101 and the aluminum electrolytic anode carbon block 400 when moving between adjacent limit members 211.

[0050] According to a continuous electrolytic aluminum anode carbon block slotting machine according to an embodiment of the present application, on the basis of Example 1, a movable frame 200 is provided with a buffer tank 220, and a loading frame 300 is provided with a fixed rod 310 which is sealed and slidably connected to the buffer tank 220.

[0051] The buffer tank 220 is filled with liquid medium, the sliding direction of the fixed rod 310 is the same as the moving direction of the loading frame 300, the fixed rod 310 is located in the buffer tank 220, and the rod body is sleeved with a first buffer plate 311, the first buffer plate 311 is perpendicular to the fixed rod 310, and a plurality of first through holes 3111 are evenly distributed on the first buffer plate 311, and the edge of the first buffer plate 311 is sealed and slidably matched with the inner wall of the buffer tank 220.

[0052] The above arrangement can achieve that the fixing rod 310 moves with the loading frame 300, and the fixing rod 310 drives the first buffer plate 311 to slide in the buffer tank 220, and the liquid medium in the buffer tank 220 flows from one side of the first buffer plate 311 to the other side through the first through hole 3111, generating flow resistance.

[0053] The working process of this embodiment is similar to that of Embodiment 1, and is described in detail as follows: The loading frame 300 squeezes the first set of limit members 211 abutting against it, forcing the first spring 213 on the first set of limit members 211 to be compressed, and the loading frame 300 moves toward the second set of limit members 211, and the loading frame 300 drives the fixed rod 310 to move, and the fixed rod 310 drives the first buffer plate 311 located in the buffer tank 220 to move, and the resistance generated by the flow of the liquid medium in the buffer tank 220 through the first through hole 3111 of the first buffer plate 311 is transmitted to the electrolytic aluminum anode carbon block 400, so that the cutting resistance between the rotating saw blade 101 and the electrolytic aluminum anode carbon block 400 is the movement resistance of the first buffer plate 311, which helps to buffer the drastic changes in the cutting resistance.

[0054] Example 3 The present embodiment discloses a continuous electrolytic aluminum anode carbon block slotting machine, which is further improved on the basis of the second embodiment to reduce the violent fluctuations generated when the rotating saw blade 101 cuts the electrolytic aluminum anode carbon block 400.

[0055] Reference Figure 3 The buffer tank 220 is provided with a fixed frame 230, and the fixed frame 230 is slidably connected to a sliding frame 231, (refer to Figure 5 ) The sliding frame 231 includes a connecting frame 2313 located above the fixed frame 230, a one-way limiting rack 2311 located below the fixed frame 230, and a connecting rod 2312 that slides vertically through the fixed frame 230, the upper and lower ends of the connecting rod 2312 are respectively connected to the connecting frame 2313 and the one-way limiting rack 2311, and the connecting rod 2312 between the fixed frame 230 and the connecting frame 2313 is sleeved with a tension spring 233, and the upper and lower ends of the tension spring 233 are respectively connected to the connecting frame 2313 and the fixed frame 230.

[0056] Accordingly, (refer to Figure 5 ) A limiting block 312 is provided at the upper part of one end of the fixing rod 310 away from the loading frame 300 and cooperates with the one-way limiting rack 2311.

[0057] Reference Figure 2 The connecting frame 2313 is provided with a support rod 232, and the support rod 232 is in a Z-shaped structure. One end of the support rod 232 is located on one side of the charging frame 300 and is connected to the connecting frame 2313, and the other end extends to the other side of the charging frame 300 and has an inclined surface at its end, which is aligned with the upper edge of the n-shaped baffle 202. (Refer to Figure 4 ) A channel 302 is provided at the upper portion of the loading frame 300 for the support rod 232 to pass through, and a distance is left between the upper and lower surfaces of the support rod 232 and the upper and lower inner walls of the channel 302.

[0058] The above setting can be realized that when the limit block 312 contacts the one-way limit rack 2311, the fixed rod 310 can only move in one direction; when the support rod 232 abuts and slides against the n-shaped baffle 202, the support rod 232 drives the connecting frame 2313, the connecting rod 2312 and the one-way limit rack 2311 to rise, the limit block 312 separates from the one-way limit rack 2311, and the tension spring 233 is in a stretched state.

[0059] The working process of this embodiment is similar to that of Embodiment 2, and is described in detail as follows: When the rotating saw blade 101 cuts the high-density area on the electrolytic aluminum anode carbon block 400, the loading frame 300 drives the fixed rod 310 to move, and the limit block 312 on the fixed rod 310 always remains in contact with the one-way limit rack 2311 to prevent the fixed rod 310 from moving in the opposite direction, so as to reduce the violent fluctuations generated during the cutting of the electrolytic aluminum anode carbon block 400 by the rotating saw blade 101, thereby allowing the rotating saw blade 101 to maintain a relatively stable cutting force on the electrolytic aluminum anode carbon block 400.

[0060] After the slotting of the electrolytic aluminum anode carbon block 400 is completed, the moving frame 200 drives the loading frame 300 to move in the opposite direction along the slide rail 201 to the initial position.

[0061] First, the inclined surface at the end of the support rod 232 contacts the upper edge of the n-shaped baffle 202; Then, the upper edge of the n-shaped baffle 202 slides along the inclined surface until it contacts the bottom surface of the support rod 232, that is, the support rod 232 is lifted to the upper surface of the n-shaped baffle 202, and accordingly, the support rod 232 drives the connecting frame 2313, the connecting rod 2312 and the one-way limiting rack 2311 to be lifted synchronously, at which time, the tension spring 233 is in a stretched state, and the one-way limiting rack 2311 is separated from the limiting block 312; Next, the loading frame 300 moves to contact the n-shaped baffle 202 . As the moving frame 200 continues to move, the first buffer plate 311 moves to one end of the buffer tank 220 , and the loading frame 300 and the moving frame 200 return to their initial positions.

[0062] Example 4 The present embodiment discloses a continuous electrolytic aluminum anode carbon block slotting machine, which is further improved on the basis of the third embodiment.

[0063] Reference Figure 6 The fixing rod 310 is provided with a limiting flange 316 , a second buffer plate 313 and a limiting sliding ring 314 .

[0064] The fixing rod 310 is provided with a limiting flange 316 . The limiting flange 316 is spaced a certain distance from the first buffer plate 311 . The limiting flange 316 is located in the buffer tank 220 .

[0065] Reference Figure 5 The fixing rod 310 is sleeved with a second buffer plate 313 which is sealingly and slidably connected thereto. The second buffer plate 313 is located in the buffer tank 220. (Refer to Figure 6 ) and the second buffer plate 313 is located between the limiting flange 316 and the first buffer plate 311, the edge of the second buffer plate 313 is sealingly and slidingly matched with the inner wall of the buffer tank 220, and the second buffer plate 313 is provided with second through holes 3131, the number of the second through holes 3131 and the layout positions of the first through holes 3111 are the same, and the aperture of the second through holes 3131 is smaller than that of the first through holes 3111.

[0066] Reference Figure 6 The fixed rod 310 is sleeved with a limit slip ring 314 slidably connected thereto, the limit slip ring 314 is located in the buffer tank 220, and there is a gap between the limit slip ring 314 and the inner wall of the buffer tank 220. The limit slip ring 314 is located on the side of the second buffer plate 313 away from the first buffer plate 311. A second spring 315 is provided between the limit slip ring 314 and the second buffer plate 313. The second spring 315 is slidably sleeved on the fixed rod 310, and the two ends of the second spring 315 are respectively connected to the second buffer plate 313 and the limit slip ring 314. The gap area between the limit slip ring 314 and the buffer tank 220 is much larger than the sum of the areas of all the second through holes 3131 on the second buffer plate 313.

[0067] Reference Figure 6 Two groups of slide grooves 221 are arranged on the inner wall of the buffer tank 220. The slide grooves 221 are located at one end of the buffer tank 220 close to the loading frame 300. A limiting plate 223 is slidably connected in the slide grooves 221. A third spring 222 is arranged between the limiting plate 223 and the inner bottom surface of the slide grooves 221. Preferably, four groups of third springs 222 are arranged in the slide grooves 221 on each side. Under the action of the third springs 222, the limiting plates 223 on both sides are close to each other.

[0068] The limiting force on the limiting slip ring 314 generated by all the third springs 222 connected to the limiting plates 223 on both sides is equal to the elastic force generated by half the deformation of the second spring 315 on the limiting slip ring 314 .

[0069] Reference Figure 6 The adjacent edges of the limiting plates 223 on both sides are symmetrically provided with inclined limiting surfaces, and one side limiting plate 223 is provided with multiple inclined limiting surfaces, and the multiple inclined limiting surfaces are connected to form a wave-like structure, that is, to form continuously alternating "peaks" and "troughs".

[0070] The above arrangement can be realized, that is, the fixed rod 310 drives the first buffer plate 311 to move to fit with the second buffer plate 313, and drives the second buffer plate 313 to move, and the liquid medium flows through the second through hole 3131 and the first through hole 3111, the flow resistance of the liquid medium increases, and the corresponding movement resistance of the fixed rod 310 becomes larger, and the cutting force of the rotating saw blade 101 on the electrolytic aluminum anode carbon block 400 increases.

[0071] The first buffer plate 311 drives the second buffer plate 313 to continuously squeeze the second spring 315. Accordingly, the second spring 315 squeezes the limit plate 223 through the limit slip ring 314. When the second spring 315 is deformed by more than half, the limit slip ring 314 squeezes the limit plate 223 until the limit slip ring 314 passes through the first group of "peaks" and enters the first group of "troughs", and the second spring 315 recovers its elastic potential energy.

[0072] The working process of this embodiment is similar to that of Embodiment 3, and is described in detail as follows: First, when the rotating saw blade 101 cuts the high-density area on the electrolytic aluminum anode carbon block 400, the loading frame 300 drives the fixed rod 310 to move, and the loading frame 300 squeezes the first group of limit members 211 abutting against it to both sides of the loading frame 300, and the loading frame 300 moves to the second group of limit members 211. Correspondingly, the fixed rod 310 drives the first buffer plate 311 to move toward the second buffer plate 313. During the movement of the first buffer plate 311 toward the second buffer plate 313, the liquid medium mainly flows from one side of the first buffer plate 311 through the first through hole 3111 to the other side of the first buffer plate 311. The cutting resistance between the rotating saw blade 101 and the electrolytic aluminum anode carbon block 400 is regulated by using the resistance generated by the liquid medium passing through the first buffer plate 311. Secondly, if the rotating saw blade 101 has not passed through the high-density area on the electrolytic aluminum anode carbon block 400, the loading frame 300 squeezes the second group of limit members 211 to both sides thereof. At this time, the first buffer plate 311 drives the second buffer plate 313 to continue to move, and the liquid medium mainly flows from one side of the second buffer plate 313 through the first through hole 3131 and the second through hole 3111. Since the aperture of the second through hole 3131 is smaller than that of the first through hole 3111, that is, the flow area of ​​the liquid medium is reduced, the corresponding resistance is increased, the second buffer plate 313 continues to compress the second spring 315, and the resistance of the fixing rod 310 gradually increases. Accordingly, the cutting force of the rotating saw blade 101 on the electrolytic aluminum anode carbon block 400 gradually increases; Then, the loading frame 300 continues to move toward the third group of limit members 211, and the limit slip ring 314 continues to squeeze the limit plate 223. When the second spring 315 is deformed by more than half, the limit slip ring 314 squeezes the limit plate 223 to slide into the slide groove 221. The limit slip ring 314 passes through a group of "peaks" of the limit plates 223 on both sides and enters a group of "troughs". At this time, the elastic potential energy of the second spring 315 is restored, and the cutting force of the rotating saw blade 101 on the electrolytic aluminum anode carbon block 400 is reduced. As the loading frame 300 drives the fixed rod 310 to continue to move, the first buffer plate 311 drives the second buffer plate 313 to squeeze the second spring 315 again, and accordingly, the limit slip ring 314 squeezes the limit plate 223 again.

[0073] Subsequently, this process is repeated and the cutting force between the rotating saw blade 101 and the electrolytic aluminum anode carbon block 400 is regulated by gradually increasing pressure, so that the rotating saw blade 101 passes through the high-density area on the electrolytic aluminum anode carbon block 400, thereby completing continuous and stable grooving of the electrolytic aluminum anode carbon block 400 while protecting the rotating saw blade 101.

[0074] Finally, when the moving frame 200 drives the loading frame 300 to move and reset, the buffer tank 220 gradually approaches the loading frame 300, and the corresponding first buffer plate 311 moves toward one end of the buffer tank 220. The limiting flange 316 drives the second buffer plate 313 to move, and the second buffer plate 313 drives the limiting slip ring 314 to move and reset to the side of the limiting plate 223 through the second spring 315.

[0075] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
