Description

Technical Field

[0001] This utility model relates to the field of production and testing equipment technology, and in particular to a brick-dispensing device for detecting hidden cracks in ceramic tiles. Background Technology

[0002] In the tile manufacturing industry, hidden cracks are one of the key defects affecting the quality and safety of tile products. Hidden cracks in tiles are usually hidden inside the tile body or in the shallow surface layer, without obvious visible damage. However, they can easily lead to problems such as breakage and chipping during subsequent transportation, installation, and use. This not only increases the cost of rework but may also cause safety hazards. Therefore, accurate detection of hidden cracks in the tile production process is crucial.

[0003] Currently, most devices in the industry for detecting hidden cracks in ceramic tiles use automatic hammer impact detection. The core principle is to drive an automatic hammer to strike specific locations on the tile surface, utilizing the differences in sound frequencies or vibration feedback signals generated by the tile vibrations to determine the presence of hidden cracks. However, this detection method has significant limitations in practical applications and cannot meet the high-precision detection requirements of large-scale production.

[0004] Specifically, existing automatic hammer impact testing devices have a significant limitation in their detection location. Because the hammer's impact point is typically fixed, it can only detect specific areas on the tile surface (such as the center or fixed corners), failing to achieve comprehensive coverage of the entire tile surface. Furthermore, during the forming and firing processes of tiles, the location of hidden cracks is random, potentially distributed across any area of ​​the tile, especially at edges and stress concentration points in the center—areas easily missed by existing detection devices. When hidden cracks are located outside the impact range of the automatic hammer, the detection device cannot capture the abnormal signal, leading to a large number of tiles with hidden crack defects entering the market, severely impacting product qualification rates and the company's brand reputation.

[0005] Meanwhile, the effectiveness of automatic hammer impact detection is easily affected by various factors, resulting in poor detection stability. On the one hand, differences in the flatness of the tile surface lead to uneven hammer impact force. In some areas, the impact force is too light to trigger the vibration characteristics of hidden cracks, while in other areas, the impact force is too heavy, generating false damage signals. On the other hand, differences in the density of tile materials (such as porcelain tiles and earthenware tiles) result in different inherent vibration frequencies. The signal analysis parameters of existing detection devices are difficult to adapt to various tile materials, further reducing the accuracy of hidden crack detection. Therefore, existing technology still needs improvement and enhancement. Utility Model Content

[0006] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a tile dispensing device for detecting hidden cracks in ceramic tiles, so as to solve one or more problems existing in the prior art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a tile-discharging device for detecting dark cracks in ceramic tiles, comprising a detection unit arranged along the transmission direction of the ceramic tile production line, the detection unit comprising a transmission roller, a detection roller, and a drive assembly, the drive assembly being connected to the transmission roller and the detection roller respectively, for driving the transmission roller and the detection roller to rotate synchronously to convey ceramic tiles, the transmission roller and the detection roller being arranged side by side at intervals, and the roller surface height of the detection roller being the same as that of the transmission roller, the surface of the detection roller being provided with radially outwardly extending detection protrusions, the detection protrusions being distributed along the length direction of the detection roller.

[0008] In one embodiment of this utility model, the transmission roller and the detection roller are made of rigid material and are used to make rigid contact with the ceramic tile to detect internal dark crack defects.

[0009] In one embodiment of this utility model, the cross-sectional shape of the detection protrusion is crescent-shaped.

[0010] In one embodiment of this utility model, the radial protrusion height of the detection ridge is 2-15mm.

[0011] In one embodiment of the present invention, a fragment collection box is also provided below the detection unit.

[0012] In one embodiment of this utility model, the driving component is a servo motor, which drives the transmission roller and the detection roller to rotate synchronously through chain drive or synchronous belt drive.

[0013] In one embodiment of the present invention, the detection unit further includes a vibration sensing component, which includes a vibration sensor mounted on the end of the detection roller and a signal processor electrically connected to the vibration sensor.

[0014] In one embodiment of the present invention, a sorting mechanism electrically connected to the signal processor is further included. The sorting mechanism includes a pneumatic push rod and a waste guide plate, which is vertically positioned above the detection plane formed by the transmission roller and the detection roller.

[0015] As described above, the tile-discharging device for detecting hidden cracks in ceramic tiles of this invention has the following beneficial effects: By setting radially outward-extending detection protrusions on the surface of the detection roller, the tile can generate a moderate bounce when passing through the detection roller. This bouncing action makes it easier for tiles with hidden cracks to produce minute vibrations or sound changes during the bouncing process, which can then be detected by the detection device, or even directly cause the tile with hidden cracks to break, thereby effectively detecting the hidden cracks in the tile. Compared with traditional detection methods, the design of the detection protrusions does not damage the surface of the tile, ensuring the quality of the tile. Attached Figure Description

In the description of this utility model, it should be understood that the terms "up," "down," "left," and "right," etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description; they should not be construed as limitations on this utility model. Furthermore, the terms "installation," "connection," etc., should be interpreted broadly; those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0020] Please see Figures 1 to 3This invention provides a tile-discharging device for detecting hidden cracks in ceramic tiles, comprising a detection unit 1 arranged along the transmission direction of the tile production line. The detection unit 1 includes a transmission roller 2, a detection roller 3, and a drive assembly 4. The drive assembly 4 is connected to both the transmission roller 2 and the detection roller 3, driving them to rotate synchronously to convey the ceramic tiles. The transmission roller 2 and the detection roller 3 are arranged side-by-side at intervals, with the roller surface height of the detection roller 3 being the same as that of the transmission roller 2. Radially outward-extending detection protrusions 5 are provided on the surface of the detection roller 3, distributed along its length. The consistent roller surface height between the detection roller 3 and the transmission roller 2 ensures a smooth transition during the conveying process before and after detection, reducing the risk of jamming or displacement due to height differences, and further improving the operational stability and detection efficiency of the equipment.

[0021] In detail, the drive roller 2 and the detection roller 3 are made of rigid material to make rigid contact with the tile and detect internal hidden cracks. During actual operation, when the tile is conveyed forward by the drive roller 2 to the area of ​​the detection roller 3, the detection protrusions 5 on the surface of the detection roller 3 extend radially outward and are distributed along its length. As the tile passes over the detection protrusions 5, it undergoes a moderate bouncing motion. The rigid contact during this bouncing process effectively stimulates potential hidden cracks within the tile, making previously undetectable cracks visible under dynamic action, thus achieving effective detection of hidden cracks. This equipment ensures a stable conveying state of the tile during the detection process through the synchronous rotation of the drive roller 2 and the detection roller 3. Simultaneously, the design of the detection protrusions 5 ensures appropriate excitation of the tile while avoiding tile breakage due to excessive impact, improving the accuracy and reliability of the detection.

[0022] The drive component 4 is a servo motor, which simultaneously drives the transmission roller 2 and the detection roller 3 to rotate synchronously via chain drive or synchronous belt drive. The servo motor features high precision, high response speed, and high reliability, ensuring that the rotational speeds of the transmission roller 2 and the detection roller 3 are consistent, guaranteeing the stability of the tiles during transport. The chain drive or synchronous belt drive provides stable power transmission, reducing energy loss and vibration during transmission, further improving detection accuracy and equipment operational stability.

[0023] Specifically, the cross-sectional shape of the detection protrusion 5 is crescent-shaped. The streamlined design of the detection protrusion 5 effectively lifts the tile to produce the required bouncing motion, while avoiding scratches or stress concentration damage to the tile glaze that might be caused by sharp or right-angled protrusions. This achieves non-destructive testing while ensuring testing effectiveness. Specifically, the radial protrusion height of the detection protrusion 5 is 2-15mm. If the protrusion height is too small, the bouncing effect of the tile is not obvious, making it difficult to detect hidden cracks; if the protrusion height is too large, it may damage the tile. The tile ejection device in this embodiment can limit the radial protrusion height of the detection protrusion 5 to a specific range according to the product specifications, precisely controlling the amplitude of the tile bouncing. This ensures that the generated excitation energy is sufficient to trigger hidden cracks, while avoiding the risk of the tile tipping, colliding, or breaking during transportation due to excessive bouncing, thus ensuring the safety and stability of the testing process.

[0024] Preferably, a debris collection box is also included below the detection unit 1. The opening area of ​​the debris collection box matches the coverage area of ​​the detection roller 3, ensuring complete collection of tile debris that falls off during the detection process. The debris collection box features a detachable design, facilitating regular cleaning and maintenance by staff. More specifically, a buffer layer is provided inside the debris collection box to effectively reduce the impact force generated when debris falls, preventing secondary breakage and dust dispersion. Simultaneously, an anti-slip pad is designed at the bottom of the debris collection box to ensure the stability of the equipment during operation and prevent positional shift due to vibration.

[0025] To improve the automation level of the brick-making equipment, the detection unit 1 also includes a vibration sensing component, which includes a vibration sensor mounted on the end of the detection roller 3 and a signal processor electrically connected to the vibration sensor. More specifically, it also includes a sorting mechanism electrically connected to the signal processor, which includes a pneumatic push rod and a waste guide plate. The waste guide plate is vertically positioned above the detection plane formed by the transmission roller 2 and the detection roller 3.

[0026] When a tile vibrates during inspection due to the excitation of the detection protrusion 5, the vibration sensor captures the minute vibration changes at the end of the detection roller 3 in real time and transmits the collected signal to the signal processor. The signal processor analyzes and processes the received vibration data to determine whether the tile has hidden cracks. If the inspection result indicates a quality problem, the signal processor immediately sends a command to the sorting mechanism. Upon receiving the command, the pneumatic pusher moves rapidly, pushing the waste guide plate down to a predetermined position, thereby separating the problematic tile from the normal conveying path. The design of the waste guide plate ensures that unqualified tiles are guided to the debris collection box or other designated areas, avoiding mixing with qualified tiles. The entire process is highly efficient and automated, significantly improving inspection efficiency and sorting accuracy while reducing the need for manual intervention. Furthermore, the speed and force of the sorting mechanism can be adjusted according to actual production needs to accommodate tiles of different specifications and materials, further enhancing the flexibility and applicability of the equipment. This design fully reflects the optimization of the equipment in terms of functionality and practicality, providing a reliable guarantee for quality control in the tile production process.

[0027] In summary, the tile conveying device for detecting hidden cracks in ceramic tiles of this invention, by setting a detection roller 3 with detection protrusions 5 distributed along the length direction on the surface in the detection unit 1, and cooperating with the transmission roller 2 and the drive assembly 4 to achieve synchronous conveying of the ceramic tiles, can generate a moderate bounce when the ceramic tiles move with the transmission roller 2 and the detection roller 3 and pass through the detection protrusions 5. Compared with the existing automatic hammer tapping detection method, this design significantly improves the effectiveness and practicality of hidden crack detection.

[0028] Firstly, the moderate bounce generated when the tile passes through the detection protrusion 5 creates a uniform and comprehensive force on the entire tile, overcoming the limitation of existing automatic hammer tapping detection methods that can only target specific fixed locations. Because all areas of the tile are subjected to corresponding vibration and stress during the bounce, any hidden cracks randomly distributed at the edges, center, or other easily overlooked areas are fully activated by the dynamic action generated by the bounce. This effectively avoids the problem of missing hidden cracks due to a single detection location, significantly improving the detection coverage and comprehensiveness, thereby increasing the pass rate of tile products and protecting the company's brand reputation.

[0029] Secondly, this bounce-based detection method does not rely on a fixed force of impact. Instead, it achieves detection through the natural bounce generated by the contact between the tile and the detection protrusion 5. This effectively avoids the problem of uneven impact force caused by differences in the flatness of the tile surface in existing automatic hammer tapping methods. Regardless of the flatness of the tile surface, the effect of moderate bounce can be applied to the tile body relatively stably. It will not fail to trigger the characteristics of hidden cracks due to insufficient force, nor will it produce false damage signals due to excessive force. At the same time, for tiles of different materials (such as porcelain tiles and earthenware tiles), the vibration feedback generated during bounce can better adapt to their inherent characteristics, reduce the impact of material differences on the detection effect, and significantly improve the accuracy and stability of hidden crack detection.

[0030] Furthermore, the testing process of this equipment is synchronized with the tile conveying process. The tiles can be inspected for hidden cracks during normal production line operation, eliminating the need for a separate tapping inspection station and dwell time. This perfectly adapts to the pace of large-scale production, avoiding the potential impact on production efficiency that existing testing methods may have. While ensuring high-precision testing, it effectively guarantees the continuity and efficiency of tile production, reducing time and labor costs in the production process and providing strong support for enterprises to improve production efficiency. Therefore, this utility model effectively overcomes the various shortcomings of existing technologies and has high industrial application value.

[0031] It is understood that those skilled in the art can make equivalent substitutions or changes based on the technical solution and inventive concept of this utility model, and all such substitutions or changes should fall within the protection scope of this utility model.
