Description

Technical Field

[0001] This utility model relates to a charcoal block fixing device, specifically a bidirectional precision charcoal block fixing device. Background Technology

[0002] To facilitate the assembly of carbon blocks and prevent the adhering filler material from falling into the electrolytic cell and affecting the quality of the primary aluminum, the calcined layer adhering to the surface of the carbon blocks must be cleaned before they are transferred to the next process. This cleaned-off calcined layer is then recycled. Since the recycling price differs between the carbon blocks and the calcined layer, with the carbon blocks fetching several times the price of the calcined layer, and because each carbon block can weigh several tons, manual cleaning would be extremely labor-intensive, inefficient, and cause severe environmental pollution. Therefore, mechanical cleaning is typically used.

[0003] In existing technology, before using machinery to clean the charcoal blocks, a crane is used to lift the uncleaned charcoal blocks onto the feeding mechanism. Cleaning is only performed after the charcoal blocks are aligned with the cleaning mechanism on the cleaning line. Therefore, each charcoal block lifted onto the feeding mechanism needs to be positioned and secured.

[0004] When cleaning is required on two side faces along the length of the charcoal block, the other four faces are usually fixed in place. During the process of fixing and tightening the charcoal block, it is easy to damage the charcoal block, resulting in economic losses. Utility Model Content

[0005] In order to solve the problems in related technologies, this utility model provides a bidirectional precision fixing device for charcoal blocks, which solves the problem of economic loss caused by damage during the fixing process of charcoal blocks.

[0006] To solve the above problems, the following technical solutions are provided:

[0007] A bidirectional precision charcoal block fixing device includes two clamping mounting seats mounted on a clamping worktable. The two clamping mounting seats move towards each other or away from each other along the length of the clamping worktable. Each of the two clamping mounting seats has a charcoal block support platform on its adjacent side surface. Each clamping mounting seat above each charcoal block support platform has a charcoal block top limiting mechanism, which is slidably connected to its corresponding clamping mounting seat. Each charcoal block support platform has charcoal block bottom limiting mechanisms on both sides along its width direction, which are slidably connected to their corresponding charcoal block support platforms. The sliding connection is characterized in that each of the carbon block top limiting mechanisms includes a limiting member and a linear drive assembly. Each linear drive assembly is disposed on the corresponding clamping mounting base. Each linear drive assembly is linked to a connecting member. The other end of each connecting member is fixed with a vertical first connecting shaft. The other end of each first connecting shaft is fixedly connected to the corresponding limiting member. An annular notch is provided on the connecting member corresponding to the bottom outer periphery of each first connecting shaft. A pressure-holding disc spring is sleeved on the first connecting shaft corresponding to each annular notch. The bottom of each pressure-holding disc spring abuts against the connecting member.

[0008] Through the above technical solution, by setting the pressure-holding disc spring, when the linear drive assembly drives the limiting component to move downward, the pressure-holding disc spring can absorb and disperse the impact force, thereby reducing the direct impact of the limiting component on the carbon block, avoiding damage to the carbon block due to sudden pressure or impact, thus ensuring the integrity of the carbon block and reducing economic losses.

[0009] Furthermore, each of the limiting members includes an integrally formed limiting part and a connecting part, each connecting part is located at the top center position of the corresponding limiting part, and each pressure-holding disc spring abuts against the corresponding connecting part;

[0010] Each of the limiting parts has multiple columnar protrusions at its bottom, each protrusion being detachably connected to the corresponding limiting part, and the bottom end of each protrusion being frustoconical.

[0011] By using the above technical solution, multiple protrusions with cone-shaped bases are designed so that when the limiting component applies pressure to the carbon block and fixes the carbon block on the carbon block support platform, the contact area between the protrusions and the carbon block is small. As a result, the lower part of the protrusions can more easily enter the carbon block, ensuring that the carbon block is firmly fixed, thereby ensuring the smooth cleaning of the roasting layer on the carbon block in the subsequent process.

[0012] Furthermore, two first guide rails are arranged in parallel along the length of the clamping worktable, and both clamping mounting seats are slidably mounted on the first guide rails via a sliding mechanism.

[0013] Furthermore, each of the charcoal block support platforms is provided with a centering mechanism, and each of the charcoal block bottom limiting mechanisms includes a first limiting component and a second limiting component. The first limiting component and the second limiting component are respectively disposed on the corresponding centering mechanisms on both sides of the charcoal block support platform, and are both linked to the centering mechanism. The centering mechanism is used to drive the first limiting component and the second limiting component to move towards each other or backwards.

[0014] Through the above technical solution, by setting the centering mechanism, the positions of the first limiting component and the second limiting component can be adjusted according to the different length values ​​of the charcoal block, so as to avoid the concentrated distribution of the upward pressure applied by the first limiting component and the second limiting component to the charcoal block, thereby ensuring the stability of the charcoal block and ensuring the smooth cleaning of the roasting layer on the charcoal block, thus accelerating the production efficiency.

[0015] Furthermore, the centering mechanism includes a fixed frame and a motor mounted on the fixed frame. The top and bottom of the fixed frame are provided with second guide rails, and the second guide rails are arranged along the length direction of the fixed frame.

[0016] Each of the carbon block support platforms is provided with a sliding plate on the fixed frame on both sides of the width direction. Each sliding plate is linked to the motor. Multiple rollers are provided on the upper and lower parts of the side facade near the fixed frame of each sliding plate. Each roller has a limit groove on its outer curved surface, and the limit groove is adapted to the top of the second guide rail. The first limit component and the second limit component are respectively fixedly installed on the other side facade of the corresponding sliding plate.

[0017] Through the above technical solution, by setting the rollers, when adjusting the positions of the first and second limiting components, the rollers can reduce the friction between the first and second limiting components and the sliding plate, and improve the transmission efficiency, thereby accelerating the adjustment rate of the first and second limiting components on the sliding plate.

[0018] Furthermore, each of the sliding mechanisms includes a sliding fixed seat fixedly installed at the bottom of the corresponding clamping mounting seat. The bottom of the sliding fixed seat corresponding to both sides of the width of the first guide rail is respectively provided with a first bearing. The inner ring of each first bearing is fixedly connected to the corresponding sliding fixed seat through a second connecting shaft. The outer ring curved surface of each first bearing abuts against the side surface of the corresponding first guide rail.

[0019] Each of the sliding fixed seats is fixedly provided with a reverse hook plate on its side surface. Each reverse hook plate is vertically arranged. Each reverse hook plate has a third connecting shaft arranged horizontally at its bottom. Each second connecting shaft is provided with a second bearing. Each second bearing and each first bearing are ball bearings.

[0020] Through the above technical solution, ball bearings can effectively prevent dust, sand and other contaminants from entering the bearing, thereby extending the service life of the device, reducing the replacement frequency, and thus reducing investment costs.

[0021] The above solution has the following advantages:

[0022] 1. By setting the pressure-holding disc spring, when the linear drive assembly drives the limiting component to move downward, the pressure-holding disc spring can absorb and disperse the impact force, thereby reducing the direct impact of the limiting component on the carbon block, avoiding damage to the carbon block due to sudden pressure or impact, thus ensuring the integrity of the carbon block and reducing economic losses.

[0023] 2. By setting multiple protrusions with cone-shaped bottoms, when the limiting component applies pressure to the carbon block and fixes the carbon block on the carbon block support platform, the contact area between the protrusion and the carbon block is small, and the lower part of the protrusion can more easily enter the carbon block, ensuring that the carbon block is firmly fixed, thereby ensuring the smooth cleaning of the roasting layer on the carbon block in the later stage.

[0024] 3. By setting up the centering mechanism, the positions of the first and second limiting components can be adjusted according to the different length values ​​of the charcoal blocks, so as to avoid the concentrated distribution of the upward pressure applied by the first and second limiting components to the charcoal blocks, thereby ensuring the stability of the charcoal blocks and ensuring the smooth cleaning of the roasting layer on the charcoal blocks, thus accelerating production efficiency.

[0025] 4. By setting up the rollers, when adjusting the positions of the first and second limiting components, the rollers can reduce the friction between the first and second limiting components and the sliding plate, and improve the transmission efficiency, thereby accelerating the adjustment rate of the first and second limiting components on the sliding plate.

[0026] 5. Because ball bearings can effectively prevent dust, sand and other contaminants from entering the bearing, the service life of this device is extended, the replacement frequency is reduced, and thus the investment cost is reduced. Attached Figure Description

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] In a specific embodiment, such as Figures 1-6As shown, the bidirectional precision fixing device for charcoal blocks includes two clamping mounting seats 2 mounted on a clamping worktable 1. The two clamping mounting seats 2 move towards each other or away from each other along the length of the clamping worktable 1. The structure of the clamping mounting seats 2 is existing technology and will not be described in detail here. Two models capable of moving towards or away from each other, allowing the charcoal block between the two clamping mounting seats 2 to be in a clamped and free state, can be selected. Charcoal block support platforms 3 are provided on the adjacent side surfaces of the two clamping mounting seats 2. Each charcoal block support platform 3 has a corresponding clamping mounting seat 2 with a top limiting mechanism for the charcoal block. Each top limiting mechanism is slidably connected to the corresponding clamping mounting seat 2. Each charcoal block support platform 3 has bottom limiting mechanisms on both sides in the width direction of each charcoal block support platform 3. Each bottom limiting mechanism is slidably connected to the corresponding charcoal block support platform 3. The structures of the limiting mechanism and the bottom limiting mechanism of the charcoal block are existing technologies and will not be described in detail here. The top limiting mechanism of the charcoal block can be a model that can drive the connecting part 5 to move up and down, and will not be described in detail here. Each top limiting mechanism of the charcoal block includes a limiting part 4 and a linear drive assembly. Each linear drive assembly is set on the corresponding clamping mounting base 2. Each linear drive assembly is linked to the connecting part 5. The other end of each connecting part 5 is fixed with a vertical first connecting shaft 6. The bottom of each first connecting shaft 6 is provided with a pressure-holding disc spring 7. The other end of each pressure-holding disc spring 7 is fixedly connected to the corresponding limiting part 4. When the linear drive assembly drives the limiting part 4 to move downward, the pressure-holding disc spring 7 can absorb and disperse the impact force, thereby reducing the direct impact of the limiting part 4 on the charcoal block, avoiding damage to the charcoal block due to sudden pressure or impact, thus ensuring the integrity of the charcoal block and reducing economic losses.

[0037] Each limiting member 4 includes an integrally formed limiting part 401 and a connecting part 402. Each connecting part 402 is located at the top center of the corresponding limiting part 401, and each pressure-holding disc spring 7 is provided on the corresponding connecting part 402. Each limiting part 401 has multiple columnar protrusions 8 at its bottom. Each protrusion 8 is detachably connected to the corresponding limiting part 401, and the bottom end of each protrusion 8 is frustoconical. When the limiting member 4 applies pressure to the carbon block to fix the carbon block on the carbon block support platform 3, the contact area between the protrusion 8 and the carbon block is small, and the lower part of the protrusion 8 can more easily enter the carbon block, ensuring that the carbon block is firmly fixed, thereby ensuring the smooth cleaning of the roasting layer on the carbon block in the future.

[0038] Two first guide rails 9 are arranged in parallel along the length of the clamping worktable 1, and two clamping mounting seats 2 are slidably mounted on the first guide rails 9 through a sliding mechanism.

[0039] Each charcoal block support platform 3 is equipped with a centering mechanism, and each charcoal block bottom limiting mechanism includes a first limiting component 10 and a second limiting component 11. The first limiting component 10 and the second limiting component 11 are respectively set on the corresponding centering mechanisms on both sides of the charcoal block support platform 3, and are both linked to the centering mechanisms. The centering mechanisms are used to drive the first limiting component 10 and the second limiting component 11 to move towards each other or away from each other. The centering mechanisms can adjust the positions of the first limiting component 10 and the second limiting component 11 according to different length values ​​of the charcoal block, so as to avoid the concentrated distribution of the upward pressure applied by the first limiting component 10 and the second limiting component 11 to the charcoal block, thereby ensuring the stability of the charcoal block and ensuring the smooth cleaning of the roasted layer on the charcoal block, thereby accelerating the production efficiency.

[0040] The centering mechanism includes a fixed frame 12 and a motor 13 mounted on the fixed frame 12. Second guide rails 14 are provided at both the top and bottom of the fixed frame 12, and the second guide rails 14 are arranged along the length of the fixed frame 12. Sliding plates 15 are provided on the fixed frames 12 on both sides of each carbon block support platform 3 in the width direction. Each sliding plate 15 is linked to the motor 13. Multiple rollers 16 are provided on the upper and lower parts of the side facade of each sliding plate 15 near the fixed frame 12. Each roller 16 has a limit groove on its outer curved surface, and the limit groove is adapted to the top of the second guide rail 14. A first limit group... The first limiting component 10 and the second limiting component 11 are respectively fixedly installed on the other side of the corresponding sliding plate 15; the specific structure of the centering mechanism is existing technology. The centering mechanism can be a model that can drive the two sliding plates 15 to move along the second guide rail 14 after the motor 13 is started, and will not be described in detail here; when adjusting the position of the first limiting component 10 and the second limiting component 11, the roller 16 can reduce the friction between the first limiting component 10 and the second limiting component 11 and the sliding plate 15 and improve the transmission efficiency, thereby speeding up the adjustment rate of the first limiting component 10 and the second limiting component 11 on the sliding plate 15.

[0041] Each sliding mechanism includes a sliding fixed seat 17 fixedly installed at the bottom of the corresponding clamping mounting base 2. First bearings 18 are respectively provided at the bottom of the sliding fixed seats 17 on both sides of the width of the first guide rail 9. The inner ring of each first bearing 18 is fixedly connected to the corresponding sliding fixed seat 17 via a second connecting shaft. The outer curved surface of each first bearing 18 abuts against the side surface of the corresponding first guide rail 9. A hook plate 19 is fixedly installed on the side surface of each sliding fixed seat 17. Each hook plate 19 is vertically arranged, and a third connecting shaft 20 is horizontally arranged at the bottom of each hook plate 19. A second bearing 21 is provided on each second connecting shaft. Both the second bearing 21 and the first bearing 18 are ball bearings. Because ball bearings effectively prevent dust, sand, and other contaminants from entering the bearing interior, the service life of the device is extended, reducing replacement frequency and thus lowering investment costs.

[0042] Operating procedure: Adjust the distance between the two clamping mounting seats according to the width of the charcoal block. After adjustment, suspend the charcoal block in the middle of the two charcoal block support platforms. Continue to adjust the distance between the two clamping mounting seats until the charcoal block is clamped by the two clamping mounting seats.

[0043] The top limiting mechanism of each charcoal block is activated, so that each limiting component abuts against the top of the charcoal block. The position of the two sliding plates on each centering mechanism is adjusted according to the length of the charcoal block. After the adjustment is completed, the first limiting component and the second limiting component are activated, so that the output shaft of the first limiting component and the second limiting component abuts against the bottom of the charcoal block.

[0044] At this point, activate the two clamping mounting seats, causing them to move slightly away from each other, thus freeing the carbon block in the width direction.
