Description

Technical Field

[0001] This utility model relates to the technical field of honeycomb ceramic skin grafting machines, and in particular to a honeycomb ceramic skin grafting machine with a post-grafting vibration ejection function. Background Technology

[0002] As the core framework of the catalyst, the honeycomb ceramic carrier requires a "skinning" process to uniformly coat its surface with a layer of catalyst slurry during manufacturing. After coating, the wet honeycomb ceramic needs to be unloaded from the fixture and transferred to the subsequent drying process. During this unloading stage, due to the viscosity of the slurry and the extreme fragility of the honeycomb pore structure of the carrier itself, achieving a stable and damage-free ejection of the finished product becomes a key issue affecting production efficiency and product yield. Improper ejection can easily lead to damage to the bottom pores of the carrier or the wet coating adhering to the pressure plate and being scratched.

[0003] In existing technologies, rigid ejector rods or blocks are commonly used to push the bottom of the honeycomb ceramic directly upwards after the skinning process, separating it from the tooling. This mechanical ejection method has a simple structure and solves the problem of automatic unloading of finished products to some extent. However, this method involves concentrated force and cannot effectively overcome the adhesion between the wet coating and the upper pressure plate.

[0004] The existing rigid ejection technology still has significant drawbacks. First, the rigid ejector block is in direct contact with the fragile bottom of the honeycomb ceramic, which can easily crush local channels and damage the product. Second, during the ejection process, due to the presence of adhesion forces, the ceramic body may suddenly loosen or shift, which may not only cause it to crack due to uneven stress, but also scratch the uncured wet coating surface, seriously affecting the product's appearance and performance. In addition, slurry debris generated during production can easily fall into the movement gaps of the ejection mechanism, accelerating its wear and affecting the long-term reliability of the equipment. Therefore, there is an urgent need for a solution that can achieve flexible, efficient, and non-destructive ejection. Utility Model Content

[0005] Purpose of the invention: The purpose of this invention is to provide a honeycomb ceramic skin grafting machine with a post-grafting vibration ejection function. By incorporating a built-in vibrator, high-frequency micro-amplitude vibrations are generated before the honeycomb ceramic is lifted, which can instantly break the adhesion between the wet coating of the honeycomb ceramic and the upper pressure plate, making the ejection process smooth and seamless. This effectively avoids damage to the bottom channels and scratches to the coating, significantly improving the product qualification rate.

[0006] Technical solution:

[0007] A honeycomb ceramic skin grafting machine with a vibration ejection function after skin grafting includes a frame, wherein the frame is equipped with a feeding mechanism, an upper pressing mechanism, a lower pressing mechanism, a scraping mechanism and an ejection mechanism;

[0008] The upper pressing mechanism includes a first lifting drive component, a first movable seat that is pulsatorically connected to the first lifting drive component, a first pressure plate that is rotatably installed at the lower end of the first movable seat, and a first rotation drive component that controls the rotation of the first pressure plate.

[0009] The pressing mechanism includes a second rotary drive component and a second rotary seat that is pulsatorically connected to the second rotary drive component.

[0010] The ejection mechanism includes an ejection drive, an ejection block, and a vibrator built into the ejection block. The ejection mechanism is installed in a through hole at the center of the second rotating seat. A bearing is provided between the through hole and the ejection block. A first mounting groove for mounting the bearing is provided on the inner sidewall of the through hole.

[0011] Furthermore, the vibrator is a piezoelectric ceramic vibrator, which is encapsulated in the mounting cavity inside the ejector block.

[0012] Furthermore, the bearing is a preloaded linear bearing.

[0013] Furthermore, the bearing is a self-lubricating plastic bearing made of POM or PTFE composite material.

[0014] Furthermore, a sealing ring is provided between the through hole and the ejector block, and a second mounting groove for installing the sealing ring is provided on the inner side wall of the through hole, and the sealing ring is located at the upper end of the bearing.

[0015] Furthermore, the portion of the sealing ring located at the outer end of the second mounting groove extends upward to be flush with the top surface of the second rotating seat.

[0016] Furthermore, the ejection drive is a pneumatic cylinder or an electric cylinder.

[0017] Furthermore, the feeding mechanism includes a feeding fixture with a first positioning groove, a first conveying component for controlling the movement of the feeding fixture, a gripping component, and a second conveying component for controlling the movement of the gripping component.

[0018] Furthermore, the scraping mechanism includes a scraper, a feeding assembly, and a horizontal drive assembly for controlling the scraper to move away from and near the lower pressing mechanism.

The front end of the scraper has a vertical discharge port. The vertical mud discharge pipe has a hollow structure and is connected to the mud inlet pipe.

[0019] Beneficial effects:

[0020] 1. By incorporating a built-in vibrator, high-frequency micro-amplitude vibrations are generated before the honeycomb ceramic is lifted. This instantly breaks the adhesion between the wet coating of the honeycomb ceramic and the upper pressure plate, making the ejection process smooth and seamless. This effectively avoids damage to the bottom channels and scratches to the coating, significantly improving the product qualification rate.

[0021] 2. By using bearings to provide precise guidance for the ejector block, the stability of the ejection movement is ensured. Simultaneously, the innovative design employing a sealing ring, extending it even to be flush with the seat surface, effectively prevents slurry debris from intruding into the moving parts, reducing wear and jamming in the mechanism and ensuring long-term stable operation of the equipment under harsh working conditions.

[0022] 3. This ejection mechanism works in conjunction with the feeding, pressing, and scraping mechanisms to form a complete automated production line. The vibratory ejection action is rapid and effective, shortening the cycle time and reducing secondary manual processing of the finished product, thereby improving overall production efficiency while ensuring quality.

[0027] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Example 1

[0029] like Figure 1-4 As shown, a honeycomb ceramic skin grafting machine with a vibration ejection function after skin grafting includes a frame 1, wherein the frame 1 is equipped with a feeding mechanism 2, an upper pressing mechanism 3, a lower pressing mechanism 4, a scraping mechanism 5, and an ejection mechanism 6.

[0030] The upper pressing mechanism 3 includes a first lifting drive 31, a first movable seat 32 that is connected to the first lifting drive 31, a first pressure plate 33 that is rotatably installed at the lower end of the first movable seat 32, and a first rotation drive 34 that controls the rotation of the first pressure plate 33.

[0031] The pressing mechanism 4 includes a second rotary drive and a second rotary seat 41 that is drively connected to the second rotary drive.

[0032] The ejection mechanism 6 includes an ejection drive 61, an ejection block 62, and a vibrator 63 built into the ejection block 62. The ejection mechanism 6 is installed in a through hole at the center of the second rotating seat 41. A bearing 64 is provided between the through hole and the ejection block 62. The inner sidewall of the through hole is provided with a first mounting groove for mounting the bearing 64. The bearing 64 provides precise linear guidance for the ejection block 62, ensuring a smooth and stable ejection process.

[0033] Furthermore, the vibrator 63 is a piezoelectric ceramic vibrator, encapsulated in the mounting cavity inside the ejector block 62. The piezoelectric ceramic vibrator can generate high-frequency micro-amplitude vibrations, effectively breaking the adhesion between the honeycomb ceramic and the upper pressure plate 33, achieving non-destructive separation.

[0034] Furthermore, the bearing 64 is a preloaded linear bearing. Preloaded linear bearings can eliminate movement backlash, improve ejection accuracy, and prevent loosening of the mechanism due to vibration.

[0035] Furthermore, the bearing 64 is a self-lubricating plastic bearing made of POM or PTFE composite material. Self-lubricating plastic bearings have good wear resistance and vibration damping properties, making them particularly suitable for use in harsh working conditions containing slurry debris.

[0036] Furthermore, a sealing ring 65 is provided between the through hole and the ejector block 62. A second mounting groove for installing the sealing ring 65 is provided on the inner wall of the through hole, and the sealing ring 65 is located at the upper end of the bearing. The sealing ring 65 effectively prevents slurry debris from entering the bearing 64, protecting the precision moving parts.

[0037] Furthermore, the portion of the sealing ring 65 located at the outer end of the second mounting groove extends upward to be flush with the top surface of the second rotating seat 42. This extended design forms an effective protective barrier, further preventing debris from falling into the movement gap.

[0038] Furthermore, the ejection drive 61 is a pneumatic cylinder or an electric cylinder. A pneumatic cylinder or an electric cylinder can provide a stable ejection force, ensuring the reliability of the ejection process.

[0039] Furthermore, the feeding mechanism 2 includes a feeding fixture 21 with a first positioning groove, a first conveying component 22 for controlling the movement of the feeding fixture, a gripping component 23, and a second conveying component 24 for controlling the movement of the gripping component 23. The feeding fixture 21 performs initial positioning of the honeycomb ceramics through the first positioning groove, and the gripping component 23 completes automatic material handling under the drive of the conveying component.

[0040] Furthermore, the scraping mechanism 5 includes a scraper 51, a feeding assembly 52, and a horizontal drive assembly 53 for controlling the scraper to move away from and closer to the lower pressing mechanism 4. The feeding assembly 52 includes a vertical mud discharge pipe 521 and a mud inlet pipe 522. The rear end of the scraper is fixedly connected to and communicates with the vertical mud discharge pipe, and the front end of the scraper has a vertical discharge port. The vertical mud discharge pipe 521 has a hollow structure and is connected to the mud inlet pipe 522. The slurry enters the vertical mud discharge pipe 521 through the mud inlet pipe 522, and then flows out evenly from the discharge port at the front end of the scraper through the cavity inside the scraper, realizing slurry replenishment while scraping the slurry.

[0041] Furthermore, the first conveying assembly 22, the second conveying assembly 24, and the lateral drive assembly 53 all employ motor lead screw assemblies. This transmission method features high precision and good stability, ensuring accurate positioning of each moving component.

[0042] Furthermore, both the first lifting drive component 31 and the longitudinal movement drive assembly 54 are cylinders. Cylinders are characterized by their simple structure and fast response speed, making them suitable for working conditions requiring rapid reciprocating motion.

[0043] Furthermore, the gripping assembly 23 includes a bidirectional lead screw assembly 231 and two gripping elements 232 adapted to the honeycomb ceramics, which are threadedly connected to the bidirectional lead screw in the bidirectional lead screw assembly. The bidirectional lead screw assembly 231 can synchronously drive the two gripping elements 232 to move towards or away from each other, thereby achieving stable clamping and release of the honeycomb ceramics.

[0044] First, the feeding mechanism 2 automatically transports the honeycomb ceramics to the processing station; then, the first pressure plate 33 of the upper pressing mechanism 3 presses the upper surface of the honeycomb ceramics, and the second rotating seat 41 of the lower pressing mechanism 4 drives the honeycomb ceramics to rotate; at the same time, the scraping mechanism 5 moves according to the preset trajectory, so that the scraper 51 maintains a constant gap with the surface of the rotating honeycomb ceramics, and completes uniform scraping; after the scraping is completed, the vibrator 63 of the ejection mechanism 6 starts to generate high-frequency vibration, and the ejection drive 61 drives the ejection block 62 to rise, ejecting the finished product without damage; throughout the process, the various mechanisms coordinate and cooperate to achieve automated operation, ensuring product quality and production efficiency.

[0045] The aforementioned lead screw assembly and cylinder are common technical means in existing mechanical transmissions, and will not be elaborated on further here.

[0046] The embodiments described above are merely illustrative of certain implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
