Description

Technical Field

[0001] This invention relates to the field of honeycomb ceramic carrier processing technology, specifically to a honeycomb ceramic carrier blank splicing and filling equipment. Background Technology

[0002] Honeycomb ceramic carriers are core components in exhaust gas aftertreatment systems, enabling catalytic purification and particulate capture. Silicon carbide honeycomb ceramic carriers are widely used due to their high temperature resistance, thermal shock resistance, and high mechanical strength. Due to limitations in ceramic sintering processes and unit size, large-section honeycomb ceramic carriers are typically difficult to form in a single process. Instead, they are obtained by splicing and bonding several smaller honeycomb ceramic carrier blanks (hereinafter referred to as blanks) together, followed by further processing. A certain width of splicing seam is left between adjacent blanks, which is filled with adhesive and cured before multiple blanks are bonded together into a single unit.

[0003] In existing splicing processes, one method relies entirely on manual labor: operators manually apply adhesive to the splicing surfaces of individual blanks, then manually position and press to fix adjacent blanks together. The width of the filler seam in this method depends on the operator's feel, and it is difficult to judge whether the seam is filled properly. This results in low production efficiency, large splicing errors, and the production capacity and finished product quality are significantly affected by the worker's skill level. Under the high consistency requirements of the automotive industry, this method can no longer meet market demands.

[0004] Another approach uses a scraping method, such as the single-row silicon carbide DPF splicing device disclosed in Chinese Utility Model Patent No. CN220118460U. This method involves first lowering a slurry tank with a scraping nozzle to abut the splicing surface of the fixed blanks. Then, a scraper moves along the splicing surface of the blanks, scraping the adhesive onto the upper end face of the blanks to form the splicing surface. Subsequently, a robotic arm stacks the scraped blanks one by one and applies pressure to make adjacent blanks adhere to each other. Although this achieves automatic adhesive application and automatic blank stacking, its essence is still to first apply adhesive to the exposed surface and then adhere and stack them. The adhesive is only applied to the exposed end face of the blanks. After adjacent blanks are adhered, it is not guaranteed that the deep gaps are continuously and densely filled. During the pressing process, the adhesive on the surface is also easily squeezed out unevenly, leaving cavities in the gaps. Furthermore, once the blanks are stacked, it is impossible to visually inspect whether the filling in the gaps is adequate. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a honeycomb ceramic carrier blank splicing and filling equipment, which can ensure the filling material in the filling gaps is dense and allows for intuitive verification of the filling state. At the same time, it protects the brittle blank from damage and improves the consistency of splicing and production efficiency.

[0006] The technical solution is as follows: a splicing and filling device for honeycomb ceramic carrier blanks, characterized in that it includes: A single-row blank clamping fixture, wherein a plurality of honeycomb ceramic carrier blanks are pre-positioned by the single-row blank clamping fixture, and there are filler gaps between the honeycomb ceramic carrier blanks. The filling mechanism is set on the worktable and is equipped with a positioning device. The single-row blank clamping fixture is positioned on the filling mechanism after being positioned by the positioning device. The filling mechanism is provided with a discharge chute corresponding to the filling gap between the honeycomb ceramic carrier blanks. A material cylinder is provided below the workbench, and a pusher plate is provided at the bottom of the material cylinder. A linear pusher device is connected to the lower end of the pusher plate. The linear pusher device can push the pusher plate to move along the material cylinder, push the adhesive in the material cylinder upward, and squeeze it into the filler gap between the honeycomb ceramic carrier blanks through the discharge groove.

[0007] A pressing mechanism is used to press a single row of blank clamping fixtures located on the filling mechanism.

[0008] Furthermore, the filling mechanism includes several stacked sealing plates, with sealing rings provided between the sealing plates and on the outside of the discharge trough. The discharge trough includes a guide groove on the bottom sealing plate, a transition groove on the middle sealing plate, and an extrusion groove on the top sealing plate. The width of the guide groove is greater than or equal to the width of the transition groove, and the width of the transition groove is greater than or equal to the width of the extrusion groove. A clearance groove is provided on the worktable for the sealing plates, and an outer sealing ring is provided between the worktable and the bottom sealing plate and on the outside of the clearance groove.

[0009] Furthermore, the positioning device employs several positioning blocks disposed on the sealing plate.

[0010] Furthermore, the upper end of the sealing plate located at the uppermost end is provided with an installation groove that communicates with the extrusion groove, and a lower forming block is fixed in the installation groove, and the lower forming block is provided with an extrusion groove accordingly.

[0011] Furthermore, a retaining ring is fixed to the outside of the material cylinder, and the retaining ring is provided with several slots. Several movable buckles are provided at the lower end of the worktable, and the material cylinder is fixed below the worktable by the movable buckles cooperating with the slots.

[0012] Furthermore, the linear feeding device includes a servo motor, the output shaft of which is connected to a drive gear that meshes with a driven gear. The driven gear is connected to a lead screw via a coupling. A lead screw nut is provided on the lead screw, and an adapter plate is fixed on the lead screw nut. The adapter plate is connected to the feeding pressure plate via a guide rod. A vertically arranged linear guide rail is also provided under the worktable. A slider that slides on the linear guide rail is slidably engaged with the linear guide rail. The slider is fixedly connected to the adapter plate. A guide platform is also provided on the worktable, and several guide sleeves are provided on the guide platform to engage with the guide rod.

[0013] Furthermore, the pressing mechanism includes a pressing plate assembly, which is connected to the piston rod of the pressing cylinder via a connecting plate. The pressing cylinder is fixed on the worktable and can drive the pressing plate assembly to press against the upper end of the honeycomb ceramic carrier blank.

[0014] Furthermore, the pressure plate assembly includes a discharge base plate, an upper forming block at the lower end of the discharge base plate, an upper discharge trough corresponding to the filler gap between the honeycomb ceramic carrier blanks on the upper forming block, a discharge panel at the upper end of the discharge base plate, the discharge panel being connected to the connecting plate, and a discharge hole communicating with the discharge trough at the upper part of the discharge base plate and the discharge panel for detecting whether the filler has filled the filler gap between the honeycomb ceramic carrier blanks and overflowing from the discharge hole; a guide rail is connected to the worktable via a bracket, and a sliding guide slider is provided on the guide rail, the guide slider being fixedly connected to the discharge panel.

[0015] Furthermore, the single-row blank clamping fixture includes a blank fixing frame and a blank fixing top plate. Bolt seats are respectively provided on both sides of the blank fixing frame, and bolts are hinged in the bolt seats. A wing nut is provided on the bolt. Bolt positioning grooves are provided on both sides of the blank fixing top plate corresponding to the wing nut. The blank fixing top plate and the blank fixing frame are locked together by the wing nut and the bolt, so that the honeycomb ceramic carrier blank is fixed in the single-row blank clamping fixture.

[0016] Furthermore, the single-row blank clamping fixture is provided with buffer pressing blocks at the upper and lower ends of the honeycomb ceramic carrier blank, and a buffer spring is provided between the blank fixing top plate and the buffer pressing block. One end of the buffer spring abuts against the blank fixing top plate, and the other end of the buffer spring abuts against the spring sleeve. The spring sleeve abuts against the buffer pressing block, and a spring sleeve mold is provided on the blank fixing top plate corresponding to the spring sleeve.

[0017] The honeycomb ceramic carrier blank splicing and filling equipment of this invention uses a single-row blank clamping fixture that pre-positions and clamps the honeycomb ceramic carrier blanks before splicing, leaving a filling gap between adjacent blanks. The filling mechanism is equipped with a discharge chute corresponding to the filling gap. The filler in the cylinder is continuously squeezed upwards from the bottom of the filling gap through the discharge chute under the push of the pusher plate. Because the filler is forcibly pressed in under the condition that the blanks on both sides of the gap are in place and the gap is sealed, the filler continuously fills the entire depth of the gap, avoiding the problem of residual cavities in the gap that is easily left by surface coating bonding methods, and significantly improving the bonding strength and consistency of the spliced ​​body. In this invention, the filling mechanism is composed of several stacked sealing plates. The discharge trough gradually converges from bottom to top, starting with a wider guide trough and transition trough, to a narrower extrusion trough. This allows the filler to be gradually gathered and stabilized during upward conveying, and precisely extruded with a cross-section that matches the filler gap, preventing the filler from dispersing and overflowing at the gap opening. Sealing rings and outer sealing rings are respectively set between the sealing plates and between the sealing plates and the worktable. An avoidance groove is set on the worktable to form a sealed channel from the material cylinder to the extrusion trough. This ensures that the pressure applied by the pusher plate is effectively applied to the filler without leakage, further guaranteeing the compactness of the filling.

[0018] In this invention, while the pressing mechanism presses the upper end of the blank, the discharge bottom plate and discharge panel are provided with an upper discharge trough and discharge hole connected to the discharge trough. The filler continues to rise from bottom to top through the filler gap and finally overflows from the top discharge hole. When filler overflows from all discharge holes, it indicates that the corresponding filler gap has been completely filled from bottom to top. This invention integrates the filling action and the detection of whether it is filled into the same material path, which can realize real-time and intuitive judgment of filling in place, and solves the problem that it is impossible to detect whether the filling in the gap is in place after the blanks are stacked in the existing process.

[0019] The cellar ceramic carrier blanks are mostly unsintered blanks, which are quite sensitive to clamping and pressing forces. This invention sets buffer pressing blocks at both ends of the blank, and sets a buffer spring between the blank fixing top plate and the buffer pressing blocks. Through the spring sleeve and the spring sleeve mold guide, the clamping force is applied evenly to the blank after elastic buffering. The pressing mechanism also flexibly presses the upper end of the blank through the pressing plate assembly, which not only ensures the stable positioning of the blank during the filling process, but also avoids the cracking and damage of the brittle blank caused by rigid clamping or pressing.

[0020] In this invention, the filler gap between adjacent blanks is pre-formed by a removable partition plate. The gap width is determined by the thickness of the partition plate and is maintained after clamping, resulting in a filler gap with a consistent width, eliminating the need for bonding pressure and manual alignment. The discharge troughs and upper discharge troughs corresponding to the filler gaps on the filler mechanism and pressure plate assembly are respectively supported by replaceable shaping blocks. By replacing the shaping blocks, honeycomb ceramic carrier blanks of different specifications and gap positions can be adapted, enabling the same equipment to have flexible production capabilities.

[0021] In this invention, the material cylinder is fixed by a groove on the retaining ring and a movable buckle at the lower end of the worktable, allowing for quick disassembly and assembly to replenish or replace the adhesive, reducing downtime. The linear feeding device uses a servo motor to drive a lead screw via a drive gear, a driven gear, and a coupling. The lead screw nut drives the adapter plate and the feeding pressure plate to move precisely upward along the vertical linear guide rail and the guide sleeve of the guide table. The feeding displacement and pressure are controllable. The lead screw has self-locking properties, which can ensure a stable and consistent filling amount in each filling gap and maintain pressure during the pressure holding stage, ensuring consistent filling.

Detailed Implementation

[0023] This embodiment provides a honeycomb ceramic carrier blank splicing and filling equipment, which includes a worktable 100, a single-row blank clamping fixture 1, a filling mechanism 2, a material cylinder 3, a linear pushing device 4, and a pressing mechanism 5. The worktable 100 is constructed with an aluminum profile frame, and its bottom is equipped with height-adjustable feet 101 for leveling and vibration reduction. The honeycomb ceramic carrier blanks 200 to be spliced ​​are pre-clamped in the single-row blank clamping fixture 1, and a filling gap 201 is left between adjacent honeycomb ceramic carrier blanks 200. This embodiment uses the splicing of four silicon carbide honeycomb ceramic carrier blanks 200 as an example, but the material and number of blanks are not limited to this.

[0024] like Figure 6 , 7As shown, the single-row blank clamping fixture 1 includes a blank fixing frame 11 and a blank fixing top plate 12. The blank fixing frame 11 is formed by an aluminum base plate 111 and an aluminum left side plate 112 and an aluminum right side plate 113 respectively erected on both sides of the base plate. It is used to support and laterally constrain the honeycomb ceramic carrier blank 200. Bolt seats 13 are respectively provided on both sides of the blank fixing frame 11. Bolts 14 are hinged in the bolt seats 13 and can swing around the bolt seats 13. Bolt positioning grooves 16 are provided on both sides of the blank fixing top plate 12 corresponding to the bolts 14. After clamping, place the bolt 14 upwards into the corresponding bolt positioning groove 16, and then tighten the wing nut 15 on the bolt 14 to lock the blank fixing top plate 12 and the blank fixing frame 11, so that the honeycomb ceramic carrier blank 200 is firmly fixed in the single-row blank clamping fixture 1. The locking method of using hinge bolts in combination with wing nuts and positioning grooves can be quickly opened and closed by hand without tools, which facilitates the quick loading and unloading of blanks.

[0025] To protect the brittle honeycomb ceramic carrier blank 200, buffer clamping blocks 17 are respectively provided at the upper and lower ends of the single-row blank clamping fixture 1 corresponding to the honeycomb ceramic carrier blank 200. The buffer clamping blocks 17 are preferably made of elastic materials such as polyurethane. The blank fixing top plate 12 and the upper buffer clamping block 17 are fixed together by a pin and a pin sleeve. A buffer spring 18 is provided between the blank fixing top plate 12 and the upper buffer clamping block 17. One end of the buffer spring 18 abuts against the blank fixing top plate 12, and the other end abuts against the spring sleeve 19. The spring sleeve 19 abuts against the buffer clamping block 17. A spring sleeve mold 191 is provided on the blank fixing top plate 12 corresponding to the spring sleeve 19 to constrain the position of the spring sleeve 19 and the buffer spring 18. The clamping force applied by tightening the wing nut 15 is first elastically buffered by the buffer spring 18, and then evenly distributed by the buffer clamping block 17 to the honeycomb ceramic carrier blank 200. This can ensure that the blank is stably positioned during the subsequent filling and clamping process, and avoid cracking of the blank caused by rigid clamping, and avoid damage to the blank during the clamping process.

[0026] The filler gaps 201 between the honeycomb ceramic carrier blanks 200 are pre-formed by removable partition plates. During clamping, four honeycomb ceramic carrier blanks 200 and the partition plates located between adjacent blanks are placed together into the blank fixing frame 11. The thickness of the partition plate is the required gap width of the filler gap 201. After the blank fixing top plate 12 is locked and the honeycomb ceramic carrier blanks 200 are clamped and positioned, the partition plates are separated. After the partition plates are removed, filler gaps 201 with the same width as the thickness of the partition plates are retained between adjacent honeycomb ceramic carrier blanks 200. Since the gap width is determined by the thickness of the partition plates, rather than by the pressure of stacking and bonding and manual alignment, filler gaps 201 with consistent width and height can be obtained, which can solve the problem of difficulty in maintaining consistent gap width. In other embodiments of the present invention, other partitioning devices can also be used to form the filler gaps 201.

[0027] like Figures 1 to 5 As shown, the filling mechanism 2 is set on the workbench 100 and is used to squeeze the adhesive from bottom to top through the filling gap 201. The filling mechanism 2 includes a number of sealing plates stacked from bottom to top. In this embodiment, the sealing plates are, in order, the sealing plate 21 at the bottom, the transition sealing plate 22 in the middle, and the transition sealing plate 23 at the top. One or more transition sealing plates 22 can be provided. In this embodiment, one transition sealing plate 22 is shown. Each sealing plate has a discharge groove in the filling gap 201 between the honeycomb ceramic carrier blank 200. This includes a guide groove 251 on the bottom sealing plate 21, a transition groove 252 on the middle transition sealing plate 22, and an extrusion groove 253 on the top transition sealing plate 23. The width of the guide groove 251 is greater than or equal to the width of the transition groove 252, and the width of the transition groove 252 is greater than or equal to the width of the extrusion groove 253, so that the discharge groove 25 gradually converges from bottom to top. When the adhesive is conveyed upward from the material cylinder 3 through the discharge groove, it is gradually gathered and stabilized, and finally precisely extruded with a narrow cross section that matches the filling gap 201, avoiding dispersion and overflow at the gap opening, and ensuring the accuracy and density of the filling.

[0028] To prevent the adhesive from leaking between layers or at the edges of the sealing plates during upward conveying, a sealing ring 24 is provided between adjacent sealing plates and on the outside of the discharge trough 25. At the same time, a clearance groove 26 is provided on the worktable 100 corresponding to the sealing plate. An outer sealing ring 27 is provided between the worktable 100 and the lowermost sealing plate 21 and on the outside of the clearance groove 26. The sealing ring 24, the outer sealing ring 27 and the clearance groove 26 together form a sealed channel from the barrel 3 to the extrusion trough 253 to prevent adhesive leakage.

[0029] The filling mechanism 2 is equipped with a positioning device. In this embodiment, the positioning device consists of several positioning blocks 28 mounted on the sealing plate. After being positioned by the positioning blocks 28, the single-row blank clamping fixture 1 is placed on the filling mechanism 2, so that the filling gap 201 between the honeycomb ceramic carrier blanks 200 is accurately aligned with the discharge trough of the filling mechanism 2.

[0030] The upper end of the transition sealing panel 23 at the top is provided with an installation groove 29 that communicates with the extrusion groove 253. The lower changing block 230 is fixed in the installation groove 29, and the extrusion groove 253 is provided on the lower changing block 230 corresponding to the filling seam 201. When it is necessary to splice honeycomb ceramic carrier blanks 200 of different specifications, different seam positions or different seam numbers, only the lower changing block 230 needs to be replaced, without replacing the entire sealing plate. This allows the same equipment to have flexible production capabilities to adapt to multiple products. The lower changing block 230 can be made of polyurethane material, so that its elasticity can form a flexible seal at the contact point with the end face of the blank, which can prevent material leakage and avoid scratching the blank.

[0031] like Figure 1 , 4 As shown in Figure 5, the material cylinder 3 is located below the worktable 100 and is used to hold the adhesive. A pusher plate 31 is provided at the bottom of the material cylinder 3, which can move up and down along the material cylinder 3 in a piston-like manner. A retaining ring 32 is fixed to the outside of the material cylinder 3, and several slots 33 are provided on the retaining ring 32. Several movable latches 34 are correspondingly provided at the lower end of the worktable 100. The material cylinder 3 is fixed below the worktable 100 by the cooperation of the movable latches 34 and the slots 33. When it is necessary to replenish or replace the adhesive, the material cylinder 3 can be removed as a whole by opening the movable latches 34, which is convenient and can effectively reduce downtime.

[0032] The lower end of the pusher plate 31 is connected to a linear pusher device 4, such as... Figure 4 , 5 As shown, the linear feeding device 4 includes a servo motor 41 mounted on it. The output shaft of the servo motor 41 is connected to a drive gear 42, which meshes with a driven gear 43. The driven gear 43 is connected to a vertically arranged lead screw 45 through a coupling 44. A lead screw nut 46 is provided on the lead screw 45, and an adapter plate 47 is fixed on the lead screw nut 46. The adapter plate 47 is connected upward to the feeding plate 31 through a guide rod 48. To ensure that the feeding plate 31 moves smoothly and vertically up and down, a linear guide rail 49 is also vertically arranged below the worktable 100. A slider 410 is provided on the linear guide rail 49 and slides with it. The slider 410 is fixedly connected to the adapter plate 47 to ensure that the feeding plate moves smoothly. At the same time, a guide table 411 is provided, and several guide sleeves 412 that cooperate with the guide rod 48 are provided on the guide table 411.

[0033] During operation, the servo motor 41 drives the lead screw 45 to rotate via the drive gear 42, driven gear 43, and coupling 44. The lead screw nut 46 then moves upward along the lead screw 45, driving the adapter plate 47 and the pusher plate 31 upward along the material cylinder 3, squeezing the adhesive in the material cylinder 3 upward and into the filling slot 201 through the discharge groove 25 of the filling mechanism 2. When rotating in the reverse direction, the pusher plate 31 moves downward to reset. Because a servo motor is used in conjunction with gear transmission and lead screw transmission, the displacement and pushing force of the pusher can be precisely controlled, ensuring a stable and consistent filling amount in each filling slot 201. The lead screw transmission has self-locking properties, which can maintain the established filling pressure during the pressure holding phase when the pusher stops, further ensuring the compactness of the adhesive in the slot and solving the problem of difficult control of the filling amount when manually extruding.

[0034] like Figures 1 to 5As shown, the pressing mechanism 5 is used to press the single row of blank clamping fixture 1 located on the filling mechanism 2 before filling. The pressing mechanism 5 includes a pressing plate assembly. The pressing plate assembly is connected to the piston rod of the pressing cylinder 51 through the connecting plate 52. The pressing cylinder 51 is vertically fixed on the worktable 100. The pressing cylinder 51 drives the pressing plate assembly to rise and fall through the extension and retraction of the piston rod, pressing or releasing the honeycomb ceramic carrier blank 200. The pressing cylinder 51 adopts a reciprocating cylinder, which facilitates the rapid lifting and lowering of the pressing plate assembly.

[0035] In this embodiment, the pressure plate assembly includes, from bottom to top, an upper forming block 533, a discharge bottom plate 531, and a discharge panel 532. An upper discharge groove 534 is provided on the upper forming block 533 corresponding to the filler seam 201 between the honeycomb ceramic carrier blanks. The discharge panel 532 is connected to the connecting plate 52. Discharge holes 535 communicating with the discharge groove 25 are provided on the upper part of the discharge bottom plate 531 and the discharge panel 532. In this embodiment, there are nine discharge holes 535 arranged in an array. The pressure plate assembly 53 is also provided with reinforcing ribs to improve the overall rigidity of the pressure plate assembly 53, ensuring uniform force and minimal deformation during pressing. To ensure the pressure plate assembly 53 can rise and fall vertically and smoothly, a guide rail 54 is connected to the worktable 100 via a bracket 56. A guide slider 55 is provided on the guide rail 54 and slides with it. The guide slider 55 is fixedly connected to the discharge panel 532 to ensure smooth movement of the pressure plate assembly.

[0036] While the pressure plate assembly is pressing the upper end of the blank, the upper discharge groove 534 on the upper forming block 533 is connected to the discharge bottom plate 531 and the discharge hole 535 on the discharge panel 532, and is connected to the discharge groove 25 of the filling mechanism 2 from bottom to top as the same material passage. In this embodiment, the setting of the pressure plate assembly combines filling and detection. After the gap is filled, the filler overflows from each discharge hole, turning the invisible filling state in the gap into a visible overflow signal, which makes it easy to judge the filling result in time, avoid missing the internal cavity, and reduce the scrap rate and rework cost.

[0037] Based on the above structure, the working process of the honeycomb ceramic carrier preform splicing and filling equipment in this embodiment is as follows: Step 1: Place four honeycomb ceramic carrier blanks into the blank fixing frame of the single-row blank clamping fixture 1, place buffer clamping blocks at the upper and lower ends respectively, cover with the blank fixing top plate, place the bolts into the bolt positioning groove and tighten the wing nuts, so that the honeycomb ceramic carrier blanks are elastically buffered and clamped and fixed; a filling gap of the same width is formed between adjacent honeycomb ceramic carrier blanks. Step 2: Move the single-row blank clamping fixture together with the honeycomb ceramic carrier blank inside it to the filling mechanism. Position it by positioning block 28 to make the filling gap and the discharge groove of the filling mechanism accurately aligned. Step 3: The pressing cylinder drives the pressing plate assembly to move downwards. The pressing plate assembly flexibly presses the upper end of the honeycomb ceramic carrier blank through the changing block, so that the blank remains stably positioned during the filling process, and the upper discharge groove of the pressing plate assembly is aligned and connected with the discharge groove of the filling seam. Step 4: The servo motor drives the lead screw to rotate, pushing the pusher plate upward along the barrel. The binder in the barrel is collected and stabilized from bottom to top through the guide groove, transition groove and extrusion groove, and then squeezed into the bottom of the filler gap and continuously fills upward along the gap. Step 5: After the adhesive fills the filler gap 201, it continues to move upwards and overflows from the top discharge hole 535 through the upper discharge chute 534 of the pressure plate assembly 53. When adhesive overflows from all discharge holes 535, it indicates that each filler gap has been completely filled from bottom to top. At this time, the material pushing is stopped. Since filling and detection share the same material passage, whether the filling is in place can be determined in real time and intuitively, which solves the problem that the filling in the gap cannot be detected after the blank is closed in the existing scraping and stacking process. Step 6: The pressure cylinder drives the pressure plate assembly to move upward and reset, the servo motor reverses to make the pusher pressure plate move downward and reset, loosen the wing nut and take out the single row of blank clamping fixture, and you can get the spliced ​​body with adjacent blanks tightly bonded and fixed by adhesive.

[0038] When changing product specifications, it is only necessary to replace the lower changing block 230 on the side of the filling mechanism 2 and the upper changing block 533 on the side of the pressure plate assembly 53, and adjust the thickness of the partition plate and the position of the positioning block accordingly to adapt to different honeycomb ceramic carrier blanks.

[0039] This invention ensures consistent filler gap width through a single-row blank clamping fixture. A material cylinder located below the worktable and a linear feeding device achieve precise bottom-up filling. A tapered discharge trough formed by stacked sealing plates further ensures dense filling. The filling status is converted into a visible overflow signal through a discharge hole connected to the filler gap at the top of the pressure plate assembly, allowing for online determination of whether the gap is full. Simultaneously, buffer clamping blocks and buffer springs protect the blanks. This invention effectively solves problems such as incomplete filling, inability to verify fullness, easy blank damage, and inconvenience in changing shapes during the splicing of fillers. It can be widely used in the splicing production of honeycomb ceramic carriers, especially silicon carbide honeycomb ceramic carriers.

[0040] It should be noted that, in the above embodiments, the material of the honeycomb ceramic carrier blank is not limited to silicon carbide, but can also be other ceramic materials such as cordierite; the number of blanks is not limited to four, and can be increased or decreased according to the finished product specifications; the number of discharge holes is not limited to nine, and can be adapted to the number and length of the filling gaps; the number of transition sealing plates in the filling mechanism can be increased or decreased; the driving method of the linear pusher is not limited to a servo motor and lead screw, but can also use electric cylinders, hydraulic cylinders, or other devices that can provide controllable linear thrust; the polyurethane used in the buffer clamping block and the discharge trough can also be replaced by other materials that combine elasticity and wear resistance. All of these are equivalent modifications of the present invention.

[0041] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.
