Description

Technical Field

[0001] This invention relates to the field of workpiece cutting technology, and more specifically to a cutting device for the production and processing of waterless clay. Background Technology

[0002] Anhydrous taphole clay is an energy-saving refractory material with energy-saving advantages covering production, blast furnace service, and the entire life cycle. Relying on formula optimization, performance upgrades, and process adaptation, it effectively reduces energy consumption and improves energy utilization. Specialized equipment for energy-saving materials is a customized equipment for energy-saving categories such as anhydrous taphole clay, insulation materials, and new refractory materials. Through optimized structure and advanced design, it reduces equipment energy consumption and enhances the energy-saving effect of materials during service while meeting special processing requirements. Anhydrous taphole clay is a key sealing refractory material for blast furnace tapholes. During production, raw materials such as corundum, silicon carbide, and clay are mixed in a mixer, then pressed into clay strips by an extruder, and finally cut to a fixed length by a cutting device to obtain finished taphole clay blocks for use in blast furnaces. In existing anhydrous clay production lines, the cutting device mostly adopts a pneumatic or hydraulically driven guillotine-type cutting mechanism. Its basic structure includes: a cutter that reciprocates perpendicular to the clay strip extrusion direction, a clay strip support platform located below or to the side of the cutter, and a fixed-length sensor to trigger the cutter's action. During operation, the clay strip is continuously output from the extruder die. When the front end of the clay strip reaches the sensor detection position, the controller drives the cutter to quickly fall or move horizontally, cutting the clay strip into clay blocks. However, during the cutting process, at the moment the cutter cuts into the anhydrous clay material, the sides of the blade edge will come into contact with the plastic... When clay is in close contact over a large area, it easily adheres to the cutting edge and accumulates, forming a stubborn clay adhesive layer. This layer solidifies repeatedly with continuous cutting operations, gradually becoming a stubborn adhesive layer that is difficult to detach on its own. Once clay adheres and accumulates on the cutting surface, the adhesive layer will continue to drag and pull the clay strip across the cutting edge during subsequent cutting operations. This results in defects such as roughening, trailing, cracking, and localized damage on the cut surface of the clay, severely damaging the appearance integrity of the anhydrous clay product. It also compromises the overall density and uniformity of the clay, significantly reducing the performance and quality of the finished product. Summary of the Invention

The centering plate is fixedly connected to two symmetrical auxiliary rods on the outside, and the auxiliary rods are slidably connected inside the auxiliary shift grooves. The return spring is adjusted by the elastic tension of the centering plate along the guide groove.

[0008] Preferably, a centering shaft is slidably connected inside the guide groove, and one end of the centering shaft is fixedly connected to one end of the return spring. A threaded hole communicating with the inside of the guide groove is opened on one side of the limiting plate, and a bolt post is screwed onto the outside of the limiting plate. The bolt post is screwed into the inside of the guide groove through the threaded hole and is movably connected to one end of the centering shaft.

[0009] Preferably, the motion component includes a stabilizing block fixedly connected to the top of the side guard and a support block fixedly connected to the top of the cutting blade. The support block is located inside the mounting frame. The bottom of the mounting frame has a migration groove that communicates with its interior to guide the movement of the stabilizing block. The portion of the stabilizing block inside the migration groove maintains a slope fit with the support block. The top of the mounting frame is fixedly connected to a second electric push rod, and the telescopic end of the second electric push rod extends into the interior of the mounting frame and is fixedly connected to the top of the support block.

[0010] Preferably, a traction block is fixedly connected to one side of the support block, and a side sliding groove is provided on the side of the stabilizing block near the support block for guiding the traction block to move, and the stabilizing block is connected to the support block through the traction block.

[0011] Preferably, each quick-change assembly includes a protrusion on one side of the side baffle for guiding the movement of the side pulley, a side support rod is fixedly connected to the top of the cutting table, and the top of the side support rod is slidably connected to one side of the side baffle, and a frame shaft is installed on the outside of the side pulley. A second rack is fixedly connected to one side of the frame shaft bracket, and a drive gear that meshes with the second rack is movably connected to the side of the side support rod near the second rack. A first rack that meshes with the drive gear is fixedly connected to the top of the side baffle, and a tooth guide groove is provided on one side of the side support rod for the stable movement of the second rack.

[0012] The technical effects and advantages provided by the present invention in the above technical solution are as follows: This invention utilizes the coordinated drive and lever linkage of the first electric push rod, the stabilizing plate, and the limiting plate to flexibly adjust the installation tilt angle of the anti-stick scraper. A wedge-shaped gap that gradually converges inward along the cutting process direction is formed between the working surface of the anti-stick scraper and the side blade surface of the cutting blade. This wedge-shaped gap can quickly capture the clay residue adhering to the blade surface and apply progressively increasing squeezing and shearing forces during the relative displacement between the two, thereby peeling off the residue and effectively eliminating the problem of local protrusions on the blade surface caused by residue adhesion and accumulation, thus improving the quality of clay cutting. This invention uses an anti-stick scraper to continuously clean the side surface of the cutting blade, ensuring that the cutting blade always maintains a clean and smooth blade surface. During the cutting operation, a uniformly distributed and stable cutting gap can be formed between the cutting blade and the side wall of the clay that is limited and shaped by the side guard, ensuring that the cutting blade falls in a regular and unbiased trajectory throughout its entire stroke, significantly improving cutting accuracy and consistency. This invention flexibly changes the elastic tension of the return spring by precisely controlling the compression amount, which can apply a uniform and stable preload to the anti-stick scraper. This allows the anti-stick scraper to autonomously adjust the local compression deformation according to the actual contact and adhesion state of both sides of the cutting blade, achieving adaptive balance of scraping pressure on both sides and optimizing the connection structure to prevent the force distribution from solidifying and the pressure difference between the two sides from being too large. This invention allows the residue after peeling and cleaning to fall in an orderly manner along a preset falling direction under its own gravity and the guiding effect of the anti-stick scraper back guide surface, and be collected in all directions by the material receiving frame arranged below. This can effectively prevent the residue from scattering and accumulating in the material falling operation area below the cutting knife, keep the working environment clean, and prevent the scattered residue from having a secondary impact on the quality of subsequent anhydrous clay cutting. When the cutting blade is driven downward by the second electric push rod, the support block moves synchronously and slides directionally along the side groove by the traction block. The outer wall of the support block and the two side connecting blocks form a gradual slope fit, which forces the two connecting blocks to move away from each other along the migration groove. This causes the side guards on both sides to automatically retract outward along the direction perpendicular to the feed direction of the taphole clay. This action makes the clamping distance between the side guards and the outer wall of the waterless taphole clay automatically widen during the cutting process. This allows the trace amount of extruded flash and fine impurity particles left on the side wall of the taphole clay from the previous round of cutting to be in a free and relaxed state without compression. This avoids the continuous compression of the inner wall of the side guards, which will press the flash and particles onto the surface of the taphole clay. This fully ensures the surface integrity and appearance quality of the outer wall of the waterless taphole clay after cutting. This invention enables the side pulley to promptly replace the planar contact structure of the side baffle during the outward retraction process, achieving a smooth transition from the sliding surface contact guidance mode to the rolling point contact guidance mode. While the side baffle retracts, it continuously provides stable lateral limiting constraints and vertical support for the waterless gunning clay, effectively preventing lateral drift, positional deviation, or overall instability of the gunning clay, and ensuring the positioning accuracy and processing continuity of the entire cutting process. This invention utilizes a side pulley that can rotate freely around its central axis via the frame shaft assembly structure, passively following the external shape changes of the anhydrous taphole clay to achieve adaptive fitting. This rolling contact method significantly reduces the sliding resistance between the anhydrous taphole clay and the guide structure, effectively reducing the phenomenon of extrusion deformation and plastic flow of the clay at the guide contact interface, further improving the cutting quality and the surface quality of the taphole clay's outer wall.

The stabilizing block 53 is connected to the support block 52 through the traction block 56. It should be emphasized that there are two stabilizing blocks 53, side sliding grooves 55, traction blocks 56 and side baffles 25. The two stabilizing blocks 53 and the support block 52 are sloped together, so that the support block 52 moves along the distance between the two stabilizing blocks 53 during downward movement. Then, the two sides of the support block 52 are squeezed or pulled relative to the two stabilizing blocks 53. Each side baffle 25 is equipped with a quick-change assembly 6 inside, and the quick-change assembly 6 is used to push the side pulley 26 to slide out along one side of the side baffle 25; Each quick-change assembly 6 includes a protrusion 62 on one side of the side baffle 25 for guiding the movement of the side pulley 26.

A tooth guide groove 67 is provided on one side of the side support rod 61 to allow the second rack 66 to move stably. The number of quick-change components 6 is the same as that of the side stop bracket 25, and they are matched with each other.

[0018] refer to Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the mounting bracket 21 is equipped with two swing components 3 inside, and the swing components 3 are used to drive the hinge seat 23 and the anti-stick scraper 24 to adjust their angles; each swing component 3 includes a limiting plate 35 installed on one side of the anti-stick scraper 24 and a first electric push rod 31 fixedly connected inside the mounting bracket 21. The top of the limiting plate 35 is fixedly connected to the bottom of the hinge seat 23, and the anti-stick scraper 24 is adjusted along the arc of one side of the cutting blade 13 through the limiting plate 35. The bottom end of the first electric push rod 31 is fixedly connected to a stabilizing plate 32. A connecting rod 33 is hinged to the side of the stabilizing plate 32 away from the cutting blade 13. A concentric shaft column 34 is installed on one side of the hinge seat 23, and one end of the connecting rod 33 extends into the interior of the centering groove 22 and is sleeved on the outside of the concentric shaft column 34. Two symmetrical tension components 4 are provided between the limiting plate 35 and the anti-stick scraper 24, and the tension components 4 are used to maintain the self-adaptability between the anti-stick scraper 24 and the cutting blade 13; the bottom of the limiting plate 35 is also provided with a fitting groove 37, and a receiving frame 36 is plugged into the fitting groove 37, and the receiving frame 36 is designed with an L-shaped structure. Each tension assembly 4 includes a guide groove 42 opened on one side of the limiting plate 35 and a centering plate 43 fixedly connected to one side of the anti-stick scraper 24. The centering plate 43 is movably connected inside the guide groove 42, and a return spring 44 is provided between the centering plate 43 and the guide groove 42. The guide groove 42 has two symmetrical auxiliary shift grooves 48 inside. The centering plate 43 is fixedly connected to two symmetrical auxiliary rods 47 outside. The auxiliary rods 47 are slidably connected inside the auxiliary shift grooves 48. The return spring 44 is adjusted by the elastic tension of the centering plate 43 along the guide groove 42. Furthermore, there are two swing components 3, which allows each anti-stick scraper 24 to be independently adjusted relative to the surface of the cutting blade 13, increasing the flexibility of the anti-stick scraper 24 adjustment. Similarly, there are two sets of tension components 4.

[0019] Working principle: When using: refer to Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, when it is necessary to carry out standardized block cutting processing of the molded anhydrous gun clay, firstly, during the overall continuous production process, the various raw materials required for the preparation of anhydrous gun clay are fully stirred and evenly mixed by the mixer 1. Then, the molded anhydrous gun clay after the mixing process is completed can be stably and continuously extruded and conveyed to the top working surface of the cutting table 12 from the discharge box 11. First, after the cutting blade 13 completes the previous round of cutting, it can move precisely along the preset motion trajectory along the internal cavity structure of the mounting frame 21 and the migration groove 51 and complete the reset operation. Then, the first electric push rod 31 smoothly pushes the stabilizing plate 32 to move vertically downward along one side of the outer wall of the support block 52 through the adjustment of its own extension stroke. At this time, during the downward displacement of the stabilizing plate 32, the connecting rod 33 is pushed to follow and complete the downward movement in the same direction. During the movement of the concentric shaft column 34, its sliding movement direction along the centering groove 22 can be limited and constrained in real time by the hinge seat 23. When the connecting rod 33 moves downward and pushes the concentric shaft column 34 to move simultaneously, the concentric shaft column 34, after being subjected to force, can drive the hinge seat 23 to make a limited range of circumferential rotation along the internal annular groove structure of the centering groove 22. Then, the concentric shaft column 34 simultaneously drives the connecting rod 33 to make a regular arc along the internal space of the centering groove 22. The linear motion simultaneously causes the connecting rod 33 to complete the synchronous adaptive adjustment of the connection angle between the stable plate 32 and the concentric column 34. As the hinge seat 23 continues to rotate, it can synchronously drive the limiting plate 35 to rotate along the internal space of the centering groove 22 and the mounting frame 21. During this linkage operation, the concentric column 34 and the limiting plate 35 can form a stable lever motion structure with the hinge seat 23 as the force fulcrum. As a result, the position movement of the limiting plate 35 can drive the installation tilt angle between the anti-stick scraper 24 and the side of the cutting blade 13 to complete the flexible adjustment. Subsequently, the second electric push rod 54 outputs driving force to drive the support block 52 to move downward as a whole and synchronously drive the cutting blade 13 to complete the downward cutting action. Because the working contact surface of the anti-stick scraper 24 and the side blade surface of the cutting blade 13 always maintain a stable tilted fit, a wedge-shaped gap structure that gradually converges inward along the downward cutting process direction of the cutting blade 13 is formed between the two. refer to Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the blasting clay residue adhering to the side of the cutting blade 13 can be quickly captured and collected by the inlet end of the wedge-shaped gap. During the relative displacement movement between the anti-stick scraper 24 and the cutting blade 13, the residue will be subjected to gradually increasing squeezing and shearing forces, thereby achieving complete separation of the residue from the cutting blade 13. After being separated and cleaned, the residue will fall orderly to the outer areas of both sides of the cutting blade 13 under its own gravity and the guiding action of the anti-stick scraper 24's back guide surface. The naturally falling residue can then be effectively collected from all directions by the receiving frame 36 arranged below, effectively preventing the residue from scattering and piling up. In the material drop area below the cutting blade 13, the anti-stick scraper 24 continuously cleans the side blade surface of the cutting blade 13 throughout the entire cleaning process, maintaining the cleanliness of the side blade surface of the cutting blade 13 for a long time. This effectively eliminates the problem of local protrusion on the blade surface caused by residue adhesion and accumulation. The cleaning structure of the anti-stick scraper 24 and the cutting structure of the cutting blade 13 work together to ensure that when the cutting blade 13 cuts downwards, a uniformly distributed and stable cutting gap can be formed between the clean and smooth blade surface and the clay side wall limited and shaped by the side baffle 25. This completely avoids the problem of residue interference and ensures that the cutting blade 13 has a regular and unbiased cutting trajectory throughout the entire falling process. refer to Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, when precise adjustment of the scraping and pressing force between the anti-stick scraper 24 and the cutting blade 13 is required, the bolt post 41 is manually rotated to engage and match the external thread structure on the outside of the bolt post 41 with the internal thread structure inside the threaded hole 46. This causes the bolt post 41 to slowly advance along the internal channel of the threaded hole 46 into the depth of the guide groove 42. At this time, the movement of the end of the bolt post 41 can simultaneously push the centering shaft post 45 to complete the same-direction precise displacement along the internal cavity of the guide groove 42. During the displacement process, the centering shaft post 45 can simultaneously push the return spring 44 and the centering plate 43 to slide smoothly along the internal space of the guide groove 42. At the same time, when the centering plate 43 moves, it will simultaneously drive the auxiliary rod 47 to move in a direction along the internal track of the auxiliary transfer groove 48. When the auxiliary rod 47 is displaced to the limit position and forms a groove with the inner wall of the auxiliary transfer groove 48, the auxiliary rod 47 moves in a direction. After the rigid contact limit is reached, the centering disk 43 will no longer be able to move along the inside of the guide groove 42. Thus, under the continuous pushing and moving action of the centering shaft 45, the elastic extension and compression of the return spring 44 between the centering disk 43 and the centering shaft 45 can be precisely adjusted. This allows for flexible control of the elastic tension of the return spring 44 itself. At the same time, relying on the elastic support of the centering disk 43 and the return spring 44, a uniform and stable pre-tightening force can be continuously applied to the overall anti-stick scraper 24. This ensures that the anti-stick scraper 24 can autonomously adjust the degree of local compression deformation according to the actual contact and adhesion state of the left and right sides of the cutting blade 13. This keeps the scraping contact pressure on both sides of the cutting blade 13 balanced and consistent, eliminating the defects of the traditional rigid connection structure where the force distribution is solidified and the pressure difference on both sides is too large. This achieves adaptive and balanced adjustment of the scraping pressure on both sides of the anti-stick scraper 24. Figure 1 , Figure 2 , Figure 6 and Figure 7As shown, secondly, during the process of the cutting blade 13 being driven downward and gradually approaching the anhydrous taphole clay to be cut and carrying out the cutting operation, the anhydrous taphole clay to be cut can be precisely constrained and limited to the central working area directly below the cutting blade 13 by the limiting and guiding effect of the inner guide surface of the two side baffles 25 symmetrically arranged on both sides. This effectively ensures that the taphole clay will not shift or swing to the left or right during the entire cutting process. Then, the second electric push rod 54 continuously outputs driving force, driving the support block 52 to move smoothly downward along the internal frame structure of the mounting frame 21. During the downward movement of the support block 52, the cutting blade 13 is simultaneously driven to complete the synchronous downward cutting action along the internal channel of the mounting frame 21 and the migration groove 51. At the same time, during the downward movement of the support block 52, the two traction blocks 56 assembled on both sides will also be driven to slide in a direction along the internal track of the two side sliding grooves 55, thereby forming a connection between the outer walls of the left and right sides of the support block 52 and the two connecting blocks 53. The gradual slope fit structure, and as the support block 52 continues to move down, the distance between the two connecting blocks 53 and the fit gap of the support block 52 will continue to increase, thereby causing the two connecting blocks 53 to move away from each other along the internal space of the migration groove 51. As the two connecting blocks 53 move in opposite directions synchronously, they can directly drive the two side baffles 25 connected to the outside to move synchronously, forcibly pushing the side baffles 25 to slowly move outward along the horizontal direction perpendicular to the feed and conveying axis of the waterless tapping clay. This allows the clamping distance between the side baffles 25 and the outer wall of the waterless tapping clay to automatically widen and increase during the cutting operation. This allows the trace amount of extruded flash and fine particle impurities remaining on the surface of the tapping clay side wall from the previous cutting process to be in a free and relaxed state without compression within the widened gap. This completely avoids the situation where the inner wall of the side baffles 25 continuously compresses and presses the flash and particles onto the surface of the tapping clay, thus fully ensuring the surface integrity and appearance quality of the outer wall of the waterless tapping clay after cutting. refer to Figure 1 , Figure 2 , Figure 6 , Figure 7 and Figure 8As shown, during the outward widening and retraction of the side support 25, the first rack 63 mounted on the inner side can simultaneously drive the first rack 63 to complete a directional translational movement along the direction of force. Then, the first rack 63 drives the drive gear 65 to rotate along the outer wall of the side support rod 61 via tooth meshing. While the drive gear 65 continues to rotate, it maintains a stable meshing transmission relationship with the second rack 66 below, thus simultaneously driving the second rack 66 to move directionally along the internal guide track of the toothed guide groove 67. As the second rack 66 continues to move forward, it can push the frame shaft bracket 64 along the convex... The internal groove structure of groove 62 completes the guiding sliding displacement, causing the outer circular rolling surface of the side pulley 26 to slightly protrude from the inner wall of the side baffle 25 along the normal direction of the inner wall of the groove 62. As the inner wall of the side baffle 25 gradually moves away from the outer wall of the waterless tapping clay, the slightly protruding side pulley 26 can always maintain a close contact with the outer surface of the waterless tapping clay. The side pulley 26 completely replaces the original planar contact structure of the side baffle 25, stably undertaking the lateral limiting constraint and vertical support limiting function in the waterless tapping clay cutting process, and smoothly realizing the smooth switching of the equipment from the traditional sliding surface contact guiding mode to the rolling point contact guiding mode. refer to Figure 2 , Figure 6 , Figure 7 and Figure 8 As shown, this effectively prevents the anhydrous clay from losing its lateral limiting constraint and causing lateral drift, positional deviation, or overall instability when the side baffle 25 retracts and adjusts outward. This ensures that the anhydrous clay maintains the continuity and positioning accuracy of the cutting position throughout the entire process, before, during, and after the cutting blade 13 enters. At the same time, as the side baffle 25 continues to retract, the side pulley 26 slides out along the inside of the groove 62 and comes into contact with the outer wall of the anhydrous clay. The side pulley 26 can rotate freely around its own central axis through the assembly structure of the frame shaft bracket 64. The rolling structure of the side pulley 26 optimizes the frictional contact state of the material guiding contact surface in advance, so that the side pulley 26 can passively follow the external shape change of the anhydrous clay and adapt to fit, greatly reducing the sliding resistance between the anhydrous clay and the guiding structure throughout the cutting process, and effectively reducing the phenomenon of extrusion deformation and plastic flow of clay at the guiding contact interface.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
