Description

Technical Field

[0001] This utility model relates to the field of skin grafting technology for ceramic honeycomb carriers, specifically a skin grafting machine for honeycomb ceramic carriers. Background Technology

[0002] In existing technologies, to increase the structural strength of the carrier and give the honeycomb ceramic carrier a larger specific surface area, it is necessary to perform skin grafting on the honeycomb ceramic carrier. Skin grafting can form an additional protective layer on the carrier surface, increasing the overall strength of the carrier, improving its impact and wear resistance, and making it less prone to cracking or damage during use. Furthermore, skin grafting can adjust the surface properties of the honeycomb ceramic carrier, such as surface roughness and porosity, and help optimize the bonding force between the carrier and the catalyst or other functional coatings, so that the catalyst can be more uniformly loaded on the carrier surface, improving the efficiency and stability of the catalytic reaction.

[0003] In existing technologies, slurry coating is commonly used to achieve skin grafting on honeycomb ceramic carriers. The most commonly used equipment is the skin grafting machine, such as the "Adjustable Skin Grafting Machine" disclosed in authorization announcement number CN219597017U; and the "Vertical Automatic Skin Grafting Device for Honeycomb Ceramic Carriers" disclosed in application publication number CN110606770A. The technical features of the above solutions all lie in the specific fixing process of the honeycomb ceramic carrier. The above solutions all use a pressure plate with a spring assembly to press the honeycomb ceramic carrier, so that the honeycomb ceramic carrier can be well pressed and fixed without damage. However, in addition to the pressing and fixing process, there are many other problems in the existing honeycomb ceramic carrier technology.

[0004] For example, in the specific slurry coating process, after the slurry is sprayed onto the surface of the honeycomb ceramic carrier, it is scraped off with a scraper to form a uniform layer of slurry, thus completing the skin grafting. However, it often happens that the slurry overflows from the top and bottom of the scraper, causing it to be applied upwards or downwards onto the pressure plate and work station plate, seriously affecting the overall work efficiency and skin grafting quality. In addition, the control of the amount of slurry is quite important. If the amount of slurry dispensed is too small, it will affect the surface coating effect of the honeycomb ceramic carrier, but this can be solved by simply increasing the amount of slurry. However, if too much slurry is applied, it will lead to more overflow, further affecting the skin grafting quality and efficiency.

[0005] Therefore, in order to solve the above problems, it is necessary to develop a skin grafting machine for cellular ceramic carriers with a reasonable structure that improves work efficiency and quality. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by providing a skin grafting machine for honeycomb ceramic carriers; the technical solution is as follows:

[0007] A skin grafting machine for a honeycomb ceramic carrier includes a vertically placed rotary variable frequency motor, a station rotating seat mounted on the main shaft of the rotary variable frequency motor, on which a honeycomb ceramic carrier for skin grafting is placed; and a servo screw mechanism for pressing the honeycomb ceramic carrier is provided above the station rotating seat, which drives the honeycomb ceramic carrier to rotate accordingly under the action of the rotary variable frequency motor and the servo screw mechanism.

[0008] Furthermore, one side of the honeycomb ceramic carrier is equipped with a scraper seat that can be adjusted up and down as well as left and right. The scraper seat contains a slurry chamber, which is connected to a sprayer. The inner end face of the slurry chamber is provided with a discharge port, the position of which corresponds to the outer wall of the honeycomb ceramic carrier. The slurry sprayed from the discharge port is applied to the outer wall of the honeycomb ceramic carrier and is evenly scraped by the inner end face of the scraper seat.

[0009] Furthermore, the inner end face of the scraper seat is set as an arc-shaped end face corresponding to the outer wall of the honeycomb ceramic carrier, and the slurry chamber is set in the middle position of the scraper seat, with the corresponding discharge port located in the middle position of the arc-shaped end face. The arc-shaped end face is very important for skin grafting in this device, and the slurry chamber is set in the middle position, making the structure more reasonable.

[0010] Furthermore, the upper and lower parts of the arc-shaped end face inside the scraper seat are also provided with anti-overflow plates to prevent slurry from overflowing, and the distance between the upper and lower anti-overflow plates is adapted to the thickness of the honeycomb ceramic carrier to be grafted. When the scraper seat moves toward the honeycomb ceramic carrier, the upper and lower anti-overflow plates are located at the upper and lower end faces of the honeycomb ceramic carrier, so that the honeycomb ceramic carrier is wrapped between the upper and lower anti-overflow plates. The design of the anti-overflow plates is mainly to prevent the slurry from overflowing from the upper and lower sides, so the distance between the upper and lower plates should be set to be consistent with the thickness of the ceramic carrier.

[0011] Furthermore, the outlet of the slurry chamber is located between the upper and lower anti-overflow plates, and the outlet is evenly distributed. Since the honeycomb ceramic carrier itself is set between two anti-overflow plates, the outlet also needs to be set between the two anti-overflow plates, and the outlet needs to be evenly distributed so that the slurry can be sprayed onto the surface of the honeycomb ceramic carrier in a more reasonable manner.

[0012] Furthermore, the main shaft of the servo screw mechanism extends downward and a rotary bearing is installed at the shaft end. A pressure plate is installed at the lower end of the rotary bearing. The position of the pressure plate corresponds to the position of the rotating workstation below. The servo screw mechanism drives the pressure plate to press down and fix the honeycomb ceramic carrier on the rotating workstation. The pressing and fixing of the honeycomb ceramic carrier is also described in the prior art. The technical solution of this application is to use the rotary bearing to specifically install the pressure plate, and then use the pressure plate to specifically press and fix the honeycomb ceramic carrier. However, the degree of pressing of the honeycomb ceramic carrier is set according to the actual situation.

[0013] Furthermore, it also includes a horizontal fixed seat, on which a horizontal lead screw moving mechanism is installed, and on which a vertical electric lifting mechanism is installed, and the scraper seat is correspondingly installed on the main shaft of the electric lifting mechanism; so that the scraper seat can be adjusted in the up and down and left and right directions.

[0014] Furthermore, the lateral lead screw moving mechanism includes a lead screw motor, a lead screw guide rail, a lead screw shaft, and a lead screw seat. The electric lifting mechanism is correspondingly mounted on the lead screw seat, and the electric lifting mechanism moves left and right through the lead screw seat.

[0015] Beneficial effects: This utility model has the following beneficial effects:

[0016] 1) In this device, the position of the honeycomb ceramic carrier can be fixed and the pressing and rotating work can be realized by the cooperation of the rotary frequency conversion motor and the servo screw mechanism. The vertical and horizontal position adjustment of the scraper seat can be realized by the horizontal screw moving mechanism and the vertical electric lifting mechanism, thereby realizing the adjustment in various directions during skin grafting. The structure is reasonable and easy to use.

[0017] 2) This device specifically includes a scraper seat structure, with a slurry chamber inside the scraper seat. The inner end face of the scraper is set as an arc-shaped end face. A spraying machine is connected through the slurry chamber, and a discharge port is set at the front end of the slurry chamber to achieve slurry spraying onto the surface of the honeycomb ceramic carrier, thus realizing skin grafting.

[0018] 3) In the specific skin grafting process, this device relies on the arc-shaped end face of the inner side of the scraper seat to apply the skin graft. The structure is reasonably designed, and the distance between the honeycomb ceramic carrier and the scraper seat can be adjusted by the transverse screw moving mechanism, thereby adjusting the skin graft thickness. The structure is reasonable.

[0019] 4) This device also has anti-overflow plates at the upper and lower positions of the scraper seat to prevent slurry from overflowing from the upper and lower sides. The ingenious design prevents slurry from being smeared on the pressure plate or work station plate, improving work efficiency and reducing work accidents. Attached Figure Description

[0025] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. These embodiments are implemented based on the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0026] like Figure 1 As shown, a skin grafting machine for a honeycomb ceramic carrier includes a vertically placed rotary variable frequency motor 1. A station rotary seat 2 is mounted on the main shaft of the rotary variable frequency motor 1, and a honeycomb ceramic carrier 3 for skin grafting is placed on the station rotary seat 2. A servo screw mechanism 4 for pressing down the honeycomb ceramic carrier 3 is provided above the station rotary seat 2. Under the action of the rotary variable frequency motor 1 and the servo screw mechanism 4, the honeycomb ceramic carrier 3 is driven to rotate accordingly.

[0027] like Figure 2 As shown, a scraper seat 5 that can be adjusted up and down and left and right is also provided on one side of the honeycomb ceramic carrier 3. A slurry chamber 6 is provided inside the scraper seat 5. A sprayer 7 is connected to the outside of the slurry chamber 6. A discharge port 8 is provided on the inner end face of the slurry chamber 6. The position of the discharge port 8 corresponds to the outer wall of the honeycomb ceramic carrier 3. The slurry sprayed from the discharge port 8 is coated on the outer wall of the honeycomb ceramic carrier 3 and is evenly scraped by the inner end face of the scraper seat 5.

[0028] The inner end face of the scraper seat 5 is set as an arc-shaped end face 9 corresponding to the outer wall of the honeycomb ceramic carrier 3, and the slurry chamber 6 is set at the middle position of the scraper seat 5, and the corresponding discharge port 8 is located at the middle position of the arc-shaped end face 9.

[0029] like Figure 3 and Figure 4As shown, the upper and lower parts of the arc-shaped end face 9 on the inner side of the scraper seat 5 are also provided with anti-overflow plates 10 to prevent slurry from overflowing. The distance between the upper and lower anti-overflow plates 10 is adapted to the thickness of the honeycomb ceramic carrier 3 to be grafted. When the scraper seat 5 moves toward the honeycomb ceramic carrier 3, the upper and lower anti-overflow plates 10 are located at the upper and lower end faces of the honeycomb ceramic carrier 3, so that the honeycomb ceramic carrier 3 is wrapped between the upper and lower anti-overflow plates 10. The discharge port 8 of the slurry chamber 6 is located between the upper and lower anti-overflow plates 10, and the discharge port 8 is evenly distributed.

[0030] The main shaft of the servo screw mechanism 4 extends downward and a rotary bearing 11 is installed at the shaft end. A pressure plate 12 is installed at the lower end of the rotary bearing 11. The position of the pressure plate 12 corresponds to the position of the workstation rotary seat 2 below. The servo screw mechanism 4 drives the pressure plate 12 to press down and fix the honeycomb ceramic carrier 3 on the workstation rotary seat 2. It also includes a transverse fixed seat 13. A transverse screw moving mechanism is installed on the transverse fixed seat 13. A vertical electric lifting mechanism 14 is installed on the transverse screw moving mechanism. The scraper seat 5 is correspondingly installed on the main shaft of the electric lifting mechanism 14. This allows the scraper seat 5 to achieve position adjustment in the up and down and left and right directions. The transverse screw moving mechanism includes a screw motor 15, a screw guide rail 16, a screw shaft 17 and a screw seat 18. The electric lifting mechanism 14 is correspondingly set on the screw seat 18. The screw seat 18 drives the electric lifting mechanism 14 to move left and right.

[0031] The rotary variable frequency motor 1 of this device is a commonly used motor in existing applications, therefore its structure is not described in detail. The rotary variable frequency motor 1 drives the rotating workstation 2 on its main shaft to rotate. In this device, the honeycomb ceramic carrier 3 to be grafted needs to be placed on the rotating workstation 2. The position of the honeycomb ceramic carrier 3 on the rotating workstation 2 is predetermined. The specific technical solution of this device is not involved, but the technical solutions disclosed in authorization announcement number: CN219597017U and application publication number: CN110606770A can be referenced. Simultaneously, the servo screw mechanism 4 set on the upper side of this device completes the clamping and fixing of the honeycomb ceramic carrier 3. In this device, the main shaft of the servo screw mechanism 4 extends downward and is correspondingly equipped with a rotary bearing 11. The pressure plate 12 is correspondingly mounted on the rotary bearing 11. The rotary bearing 11 of this device is a very common existing bearing structure. After the pressure plate 12 is installed on the rotary bearing 11, it can press down on the honeycomb ceramic carrier 3 along with the main shaft of the servo screw mechanism 4. However, the specific force needs to be controlled accordingly to avoid damaging the honeycomb ceramic carrier 3 while ensuring that the honeycomb ceramic carrier 3 rotates together with the station rotary seat 2. The above technical solution is also very common in the existing technology. It is mainly to realize the rotation of the honeycomb ceramic carrier 3 to prepare for subsequent skin grafting.

[0032] This device also includes a structure for the scraper seat 5 to move vertically and horizontally. The horizontal movement is primarily achieved through a transverse lead screw mechanism, a common structure in existing technology. This mechanism converts the rotational motion of the lead screw into linear motion. In this device, the lead screw motor 15 is specifically mounted on the transverse fixed base 13, and a lead screw shaft 17 is mounted on the main shaft of the lead screw motor 15. A lead screw seat 18 is mounted at the front end of the lead screw shaft 17, and a lead screw guide rail 16 is mounted on the transverse fixed base 13. The rod holder 18 is embedded in the lead screw guide rail 16. When the lead screw motor 15 is turned on and drives the lead screw shaft 17 to rotate, the lead screw holder 18, being confined to the lead screw guide rail 16, can move accordingly. The electric lifting mechanism 14, used to drive the scraper seat 5 to move up and down, is correspondingly installed on the lead screw holder 18. The electric lifting mechanism 14 in this device is a lifting mechanism in the prior art, and can be specifically configured as an electric push rod structure, lead screw lifting mechanism, belt or sprocket lifting mechanism, etc., all of which can be used for lifting in this device. The lower end of the main shaft of the electric lifting mechanism 14 in this device is correspondingly installed on the scraper seat 5, and the scraper seat 5 is designed to be detachable for easy maintenance and replacement.

[0033] The most important design feature of this device lies in the structure of the scraper seat 5. Unlike existing scrapers which consist of only a single plate, the scraper seat 5 in this application is designed as a scraper seat 5. Firstly, the inner end face is set as an arc-shaped end face 9, which aligns with the outer wall end face of the honeycomb ceramic carrier 3. Secondly, a slurry chamber 6 is provided within the scraper seat 5, specifically for storing slurry, and is externally connected to a spray nozzle 7 to inject slurry into the slurry chamber 6. This technical solution is disclosed in CN219597017U. The document also mentions this, so the technical objective of injecting slurry into the slurry chamber 6 can be achieved. The inner end face of the slurry chamber 6 has a discharge port 8. The slurry chamber 6 is positioned at the middle of the arc-shaped end face 9 and can approach the surface of the honeycomb ceramic carrier 3 under the action of the transverse screw moving mechanism. Therefore, when the slurry in the slurry chamber 6 is sprayed out, it is sprayed onto the surface of the honeycomb ceramic carrier 3, which rotates accordingly. Furthermore, the scraper seat 5 and the honeycomb ceramic carrier 3... The surface distance is consistent, so the slurry can be evenly applied to the surface of the honeycomb ceramic carrier 3 to achieve the skin grafting work. The transverse screw moving mechanism can adjust the distance between the arc end face 9 and the surface of the honeycomb ceramic carrier 3, thereby adjusting the thickness of the skin graft. However, during the above work process, the slurry may overflow from the upper and lower end faces, which will affect the skin grafting. This device is equipped with transversely extending anti-overflow plates 10 at the upper and lower parts of the arc end face 9. The distance between the upper and lower anti-overflow plates 10 is adapted to the thickness of the honeycomb ceramic carrier 3. Therefore, the position of the scraper seat 5 can be adjusted according to the electric lifting mechanism 14 so that the upper and lower anti-overflow plates 10 are located at the upper and lower ends of the honeycomb ceramic carrier 3. Therefore, when the slurry is sprayed from the outlet 8, the slurry will not overflow from the top and bottom due to the obstruction of the upper and lower anti-overflow plates 10. The slurry is always at the position of the arc end face 9, which can complete the skin grafting work relatively smoothly. In addition, the outlet 8 of the slurry chamber 6 is also located at the position of the outlet 8 on the upper and lower sides, ensuring the smooth skin grafting of the slurry.

All equivalent changes and modifications made in accordance with the scope of protection of this utility model patent application should be included within the scope of this utility model patent application.
