Description

Technical Field

[0001] This utility model relates to the field of ceramic production technology, and in particular to a trimming device for daily-use ceramic production. Background Technology

[0002] Everyday ceramics, widely used in daily life, involve a production process encompassing multiple stages, including raw material proportioning, forming, drying, trimming, glazing, and firing. Trimming is a crucial step in ensuring the uniformity of the ceramic product's shape and dimensions. It primarily involves using specialized tools to finely process the semi-dry outer surface of the ceramic blank, removing excess material and improving surface smoothness. Trimming equipment, as a key piece of equipment in the production of everyday ceramics, directly impacts trimming quality, production efficiency, and ease of operation through its structural design and functional configuration.

[0003] Especially in the core aspects of controlling the adaptability of the blank shape and the cleanliness of the working environment during the blank trimming process, existing blank trimming equipment has gradually revealed a series of obvious limitations and technical problems in dealing with different specifications of products, complex process requirements, and maintenance of the working environment. For example, utility model patent CN221518238U discloses a blank trimming device for daily-use ceramics production, including a worktable with four fixed legs at the four corners of the bottom end of the worktable and connecting plates on both sides of the top of the worktable. This blank trimming device for daily-use ceramics production uses connecting plates and movable blocks. By unscrewing the locking bolts from the inside of the limiting groove, the movable block is released from its fixed position. Then, the movable block slides inside the connecting plate to adjust the position of the support rod and the blank trimming blade. Adjusting the position of the blank trimming blade allows the device to trim daily-use ceramics of different diameters, thereby improving the flexibility of the device. After adjusting to the appropriate position, the locking bolts are screwed back into the limiting groove to fix the movable block, thus preventing the movable block from accidentally moving the support rod and the blank trimming blade. This solves the problem of inconvenient adjustment of the blank trimming blade position and its significant limitations.

[0004] Although the device achieves flexible adjustment of the trimming blade position through the sliding fit between the movable block and the connecting plate, improving its adaptability to ceramic blanks of different diameters, it still has many shortcomings in practical applications. Specifically, existing daily-use ceramic trimming equipment faces prominent problems such as inconvenient operation, difficulty in debris removal, and severe dust generation during trimming operations. Because the trimming process generates a large amount of ceramic debris and dust, and existing equipment lacks an effective debris collection and dust removal structure, debris accumulates on the worktable or flies into the air, not only affecting the smooth progress of subsequent trimming work but also potentially posing a health hazard to operators and increasing the difficulty of equipment maintenance. Therefore, in response to the many shortcomings of existing technology, we urgently need an innovative trimming device for daily-use ceramic production to solve these problems. Utility Model Content

[0005] The purpose of this utility model is to provide a trimming device for daily-use ceramics production, which solves the problems of inconvenient operation, difficulty in cleaning debris, and serious dust in the trimming operation of existing daily-use ceramics trimming devices.

[0006] To achieve the above objectives, this utility model provides a trimming device for daily-use ceramics production, including a cylindrical body, a rotating rod rotatably connected to the inner side of the cylindrical body, and a drive motor fixedly connected to one side of the bottom of the cylindrical body by bolts;

[0007] A bearing seat is fixedly connected to the top of the rotating rod, and the bottom end of the rotating rod passes through the bottom of the cylinder and is connected to the output shaft of the drive motor. A bearing ring is sleeved on the outside of the bearing seat, and connecting plates are fixedly connected to both sides of the bearing ring. Both connecting plates are slidably connected to the inner wall of the cylinder through vertical grooves. Fixing plates are fixedly connected to both sides of the outer wall of the cylinder, and cylinders are fixedly connected to the bottom of both fixing plates by bolts. The output shaft of the cylinder passes through the bottom of the fixing plate and is fixedly connected to the bottom of the connecting plate. Several scrapers are fixedly connected to the bottom of the rotating rod, and the bottom of all scrapers is in contact with the bottom of the inner side of the cylinder.

[0008] The cylinder has a top plate fixedly connected to both sides of the top, and a gas collection hood is fixedly connected to one side of each of the two top plates. A collection box is fixedly connected to one side of the outer wall of the cylinder, and one side of each of the two gas collection hoods is connected to one side of the collection box. A fan is fixedly connected to one side of the outer wall of the cylinder by bolts, and the inlet of the fan is connected to the bottom of the collection box.

[0009] The collection box has a filter plate fixedly connected to its inner side, and a top cover is rotatably connected to its top via a hinge.

[0010] The top sides of the two gas collection hoods are connected to each other through a top pipe, and one end of the top pipe is connected to one side of the collection box through a connecting pipe.

[0011] The bottom end of the rotating rod passes through the bottom of the cylinder via a bearing sleeve, and a bottom valve is installed on one side of the bottom of the cylinder.

[0012] The top of the bearing ring is grooved, and the inner wall of the bearing ring is fitted with the outer side of the bearing seat with a clearance.

[0013] This utility model discloses a trimming device for daily-use ceramics production. Through a cooperative structure of a bearing ring and a bearing seat, and connecting plates and vertical groove guide structures on both sides, combined with cylinder lifting control, it effectively collects and conveniently cleans debris generated during the trimming process. This solves the problem of severe debris accumulation and difficulty in cleaning in existing technologies, significantly improving the cleanliness of the working environment and reducing manual cleaning workload. Secondly, the linkage design of multiple scrapers and rotating rods at the bottom of the cylinder allows for rapid entry into a self-cleaning mode after the main trimming task is completed. The rotating action of the scrapers thoroughly removes residue from the bottom, preventing damage to the equipment due to debris residue. The design eliminates the problems of clogging and secondary pollution, improving equipment maintenance efficiency and lifespan. Furthermore, the bottom valve not only facilitates debris discharge but also enhances the controllability of the overall dust removal system, helping to maintain clean air in the workshop and reduce the impact of dust on operator health. In addition, the integrated rotating design of the bearing seat and rotating rod, combined with the stable power output provided by the drive motor, ensures uniform rotation of the ceramic blank during the trimming process, improving trimming accuracy and consistency, and meeting the high precision and efficiency requirements of modern ceramic production. Finally, the bolted detachable connection between the fixed plate and the cylinder facilitates future maintenance and replacement of cylinder components, enhancing the maintainability and flexibility of the equipment. In summary, this trimming equipment effectively solves the key technical problems of traditional equipment, such as inconvenient debris cleaning, severe dust generation, and complex operation. It also demonstrates significant advantages in improving trimming quality, enhancing the working environment, increasing automation levels, and reducing maintenance costs, showing promising prospects for promotion and application.

[0021] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0022] Please see Figure 1-5 A trimming device for daily-use ceramics production includes a cylindrical body 1, a rotating rod 18 rotatably connected to the inner side of the cylindrical body 1, and a drive motor 13 fixedly connected to one side of the bottom of the cylindrical body 1 by bolts; a bearing seat 14 is fixedly connected to the top of the rotating rod 18, and the bottom end of the rotating rod 18 passes through the bottom of the cylindrical body 1 and is connected to the output shaft of the drive motor 13 for transmission; a bearing ring 17 is sleeved on the outer side of the bearing seat 14, and connecting plates 10 are fixedly connected to both sides of the bearing ring 17, and both connecting plates 10 are slidably connected to the inner wall of the cylindrical body 1 through vertical grooves 11; a fixing plate 9 is fixedly connected to both sides of the outer wall of the cylindrical body 1, and a cylinder 12 is fixedly connected to the bottom of both fixing plates 9 by bolts, and the output shaft of the cylinder 12 passes through the fixing plate 9 and is fixedly connected to the bottom of the connecting plate 10; a plurality of scrapers 19 are fixedly connected to the bottom of the rotating rod 18, and the bottom of all scrapers 19 is in contact with the bottom of the inner side of the cylindrical body 1.

[0023] First, the ceramic blank to be repaired is placed on the support seat 14, ensuring it is stable and rotatable. Then, the drive motor 13 is started, which drives the support seat 14 and the ceramic blank on it to rotate synchronously via the rotating rod 18, providing a stable rotational connection for the operator to use tools for repair. During the repair process, ceramic debris and fine dust will naturally fall onto the support ring 17, and some fine impurities will fall into the bottom of the cylinder 1 through the gap between the support ring 17 and the support seat 14. For easier subsequent cleaning, after repair is complete, the operator starts two cylinders 12, which output shafts... Push the connecting plate 10 to slide upward along the vertical groove 11, thereby driving the bearing ring 17 to rise as a whole, so that it is separated from the top opening area of ​​the cylinder 1. At this time, the staff can easily remove the bearing ring 17 for centralized dust removal. At the same time, as the bearing ring 17 rises, the residual debris on the bottom inner side of the cylinder 1 is exposed. The operator opens the bottom valve 16 and starts the drive motor 13 again to drive the rotating rod 18 to rotate at low speed. The multiple scrapers 19 installed at the bottom of the rotating rod 18 rotate accordingly and automatically scrape and clean the residual debris on the bottom inner wall of the cylinder 1. The debris is discharged outside the equipment through the bottom valve 16, completing the entire cleaning process.

[0024] Furthermore, top plates 2 are fixedly connected to both sides of the top of the cylinder 1, and dust collection hoods 3 are fixedly connected to opposite sides of the two top plates 2. A collection box 6 is fixedly connected to one side of the outer wall of the cylinder 1, and one side of each of the two dust collection hoods 3 is interconnected with one side of the collection box 6. A fan 8 is fixedly connected to one side of the outer wall of the cylinder 1 by bolts, and the inlet of the fan 8 is interconnected with the bottom of the collection box 6. During the trimming operation, the fan 8 is started, and the fan 8 draws in air through the bottom of the collection box 6, driving the dust collection hoods 3 to extract and collect the dust generated during trimming, so that the debris and dust are concentrated into the inside of the collection box 6. This process is completed while the equipment is running, without the need for additional shutdown for cleaning. This achieves the effects of improving dust removal efficiency, improving the air quality of the working environment, and reducing the health impact of dust on operators.

[0025] Furthermore, a filter plate 15 is fixedly connected to the inner side of the collection box 6, and a top cover 7 is rotatably connected to the top of the collection box 6 via a hinge. After the dust removal operation is completed, the operator can open the top cover 7 to inspect or clean the inside of the collection box 6. The filter plate 15 is used to filter fine particles in the air, preventing them from being directly discharged into the outside environment and causing secondary pollution; at the same time, it facilitates the regular replacement or cleaning of the filter material, ensuring the long-term stable operation of the dust removal system. This achieves the effects of improving dust interception capacity, enhancing equipment maintenance convenience, and extending the service life of the system.

[0026] Furthermore, the top sides of the two dust collection hoods 3 are interconnected via top pipes 4, and one end of the top pipes 4 is connected to one side of the collection box 6 via connecting pipes 5. During the operation of the fan 8, a complete negative pressure air duct system is formed, ensuring a balanced airflow distribution among the multiple dust collection hoods 3 and avoiding incomplete dust removal due to insufficient local suction. At the same time, this structure improves the stability and collaborative operation capability of the overall dust removal system. It achieves the effects of optimizing airflow path, improving dust removal uniformity, and enhancing the overall system efficiency.

[0027] Furthermore, the bottom end of the rotating rod 18 passes through the bottom of the cylinder 1 via a bearing sleeve, and a bottom valve 16 is installed on one side of the bottom of the cylinder 1. During equipment operation, the bearing sleeve provides stable rotational support for the rotating rod 18, reducing frictional resistance and improving operational stability. During cleaning operations, the bottom valve 16 serves as a debris discharge channel. It opens after the scraper 19 completes its scraping action, allowing debris to be smoothly discharged outside the cylinder 1. When closed, it effectively prevents dust leakage. This achieves the effects of enhancing structural stability, improving debris discharge efficiency, and ensuring sealing performance.

[0028] Furthermore, the top of the bearing ring 17 is grooved, and the inner wall of the bearing ring 17 is fitted with a clearance fit to the outer side of the bearing seat 14. This allows the bearing ring 17 to effectively collect debris that falls during the trimming process, preventing it from scattering directly onto the outside of the cylinder 1 or the worktable. Simultaneously, the grooved structure helps to concentrate the debris, facilitating its removal by the cylinder 12 for subsequent unified processing. The clearance fit does not affect the normal placement and rotation of the ceramic blank. This achieves the effects of improving debris collection, reducing environmental pollution, and enhancing operational convenience.

[0029] In summary:

[0030] First, the ceramic blank to be trimmed is placed on the support seat 14, ensuring it is securely positioned in the rotating support structure at the top of the rotating rod 18. Then, the drive motor 13, fixedly connected to one side of the bottom of the cylinder 1, is started. The rotating rod 18 drives the support seat 14 and the ceramic blank on it to rotate synchronously, providing a stable rotational fit for the operator to use trimming tools for fine processing. During the trimming process, ceramic debris and fine dust naturally fall into the grooved structure at the top of the support ring 17, and some fine impurities fall into the bottom of the cylinder 1 through the gap between the support ring 17 and the support seat 14. At this time, the top plates 2 located on both sides of the outer wall of the cylinder 1 and the fixed gas collection hoods 3 begin to function. The fan 8 is started to draw air in through the bottom of the collection box 6, and under negative pressure, the gas collection hoods 3 absorb and collect the dust, allowing the debris and dust to be transported to the inside of the collection box 6 via the top pipe 4 and connecting pipe 5. The filter plate 15 is used to filter fine particles in the air to prevent secondary pollution. It can also be cleaned or the filter material replaced regularly through the top cover 7 connected by the top hinge. After the blank repair operation is completed, the operator starts the two cylinders 12 fixed at the bottom of the fixed plate 9. The output shaft pushes the connecting plate 10 to slide upward along the vertical groove 11, thereby driving the bearing ring 17 to rise as a whole and separate from the top opening area of ​​the cylinder 1, so that the staff can remove the bearing ring 17 for centralized dust removal. At the same time, after the bearing ring 17 rises, the debris remaining at the bottom of the inner side of the cylinder 1 is exposed. The operator opens the bottom valve 16 and starts the drive motor 13 again to drive the rotating rod 18 to rotate at low speed. Multiple scrapers 19 installed at the bottom of the rotating rod 18 and passing through the bottom of the cylinder 1 through the bearing sleeve rotate accordingly and automatically scrape off the residual debris at the bottom of the inner wall of the cylinder 1. The debris is discharged outside the equipment through the bottom valve 16, completing the entire cleaning process.First, through the cooperative structure of the bearing ring 17 and the bearing seat 14, and the connecting plate 10 and the vertical groove 11 guide structure set on both sides, combined with the lifting control of the cylinder 12, the debris generated during the trimming process is effectively collected and conveniently cleaned, solving the problem of serious debris accumulation and difficulty in cleaning in the prior art, significantly improving the cleanliness of the working environment and reducing the amount of manual cleaning work; Second, the linkage design of multiple scrapers 19 and rotating rod 18 set at the bottom of the cylinder 1 allows it to quickly enter the self-cleaning mode after the main trimming task is completed. The rotation of the scrapers 19 thoroughly removes the bottom residue, avoiding equipment blockage or secondary pollution caused by debris residue, and improving the maintenance efficiency and service life of the equipment; Third, the top plate 2 and the gas collection hood 3. The dust removal system, consisting of fan 8 and collection box 6, can extract dust in real time during the trimming process, greatly improving the air quality in the workshop and reducing the impact on the health of operators. Simultaneously, the complete air duct system formed by the top pipe 4 and connecting pipe 5 optimizes the airflow path, improving dust removal uniformity and overall system efficiency. Furthermore, the filter plate 15 and openable top cover 7 inside the collection box 6 enhance dust interception capabilities and system maintainability, extending equipment lifespan. Finally, the bottom valve 16 not only facilitates debris discharge but also enhances the controllability of the overall dust removal system, helping to maintain workshop air cleanliness. The rotating rod 18, with its bearing sleeve penetrating the bottom of the cylinder 1, improves rotational stability, reduces operating friction loss, and enhances the overall machine's smooth operation. In summary, this trimming equipment not only effectively solves the key technical problems of traditional equipment, such as inconvenient debris cleaning, severe dust generation, and complex operation, but also demonstrates significant advantages in improving trimming quality, improving the working environment, increasing automation levels, and reducing maintenance costs, showing promising prospects for promotion and application.
