Description

Technical Field

[0001] The utility model relates to the technical field of ceramic tile strength detection, in particular to a brick surface knocking detection device for ceramic tiles. Background Technique

[0002] Ceramic tiles are a kind of high-strength acid and alkali-resistant porcelain or stoneware building decoration materials formed by inorganic non-metallic minerals such as clay, quartz sand, and feldspar through grinding, mixing, pressing, glazing, and sintering. During the production and processing of ceramic tiles, there are defects such as hidden cracks, delamination, and hollowing in the brick blanks. By knocking the fired brick blanks with a certain force, the defects in the internal strength of the brick blanks can be detected to avoid defective products with quality defects from flowing into the market.

[0003] The application number CN201921710707.6 discloses a ceramic tile strength detection device, including an electric box, a detection device, and a detection table; the utility model forms a crank-rocker mechanism through the detection device, the first connecting rod, the second connecting rod, and the swing rod... By setting a hammer sleeve connected by a screw, weights are added to the hammer sleeve. When it is necessary to change the hammering force, the hammer sleeve can be directly removed, weights can be added, and then it can be installed on the hammer handle. The change method is simple and the detection efficiency is improved; its disadvantage is that the device drives the heavy hammer to lift and lower through the mechanical structure of the motor and several groups of connecting rods. During the detection of ceramic tiles, since the heavy hammer does not belong to free-fall motion, the continuous hammering causes the impact force of the heavy hammer on the ceramic tiles to deviate, resulting in low detection stability of the detection device, and the impact height of the heavy hammer on the ceramic tiles cannot be adjusted arbitrarily due to the limitation of the connecting rod mechanical structure, resulting in poor detection effect of the detection device.

[0040] Embodiment Three

[0041] Please refer specifically to Figure 1 and Figure 3 , bearings are provided at the bottoms of both ends of the mounting frame 302. A rotating rod is provided inside the weight 303, and both ends of the rotating rod penetrate into the bearings. The weight 303 is rotationally connected to the mounting frame 302 through the bearings and the rotating rod.

[0042] Please refer specifically to Figure 1 and Figure 3 , a placement groove is provided at the top of the lifting frame 3, and weights can be placed inside the placement groove to adjust the impact force of the weight. Moving holes are provided at both ends on one side of the lifting plate 2, and the moving rod 304 penetrates into the moving holes. The moving rod 304 is movably connected to the lifting plate 2 through the moving holes. Through the moving holes, the moving rod 304 can move with the lifting plate 2, making the up and down adjustment effect of the lifting frame 3 better.

[0043] Working principle: Before the utility model is used, the detection device is spliced with the ceramic tile conveying mechanism, so as to convey the ceramic tile to the conveying rack 1, and the counterweight is placed in the placing groove at the top of the lifting rack 3. When in use, the power is turned on, the driving roller 102 is driven to rotate by the speed regulating motor 104, and the driven roller 101 and the conveying rack 1 can be rotated through the rotating shaft. Through the mutual cooperation of the driving roller 102 and the driven roller 101, the conveying effect of the conveyor belt 103 is better, which is convenient for conveying the ceramic tile. The conveyor belt 103 is supported by the supporting roller 105, and the conveying effect of the ceramic tile is better. The rotating shaft 206 is driven to rotate by the reduction motor 205, the rotating wheel 203 is driven to rotate by the rotating shaft 206, and the cross bar 204 is driven to do a circular motion by the rotating wheel 203. The cross bar 204 doing a circular motion drives the lifting plate 301 to move upward. When it moves to the highest point, the cross bar 204 is separated from the lifting plate 301, so that the weight 303 falls freely and impacts on the ceramic tile. The weight 303 can rotate with the mounting frame 302 through the rotating rod and the bearing, which avoids affecting the conveying of the ceramic tile. The strength of the ceramic tile is detected by the impact of the weight, and the detection accuracy of the ceramic tile strength is higher. The adjusting rod 201 is rotated, and the external thread on the outer side of the adjusting rod 201 and the threaded hole at the top of the support frame 207 cooperate with each other, which can drive the lifting plate 2 to move up and down, so as to adjust the distance between the rotating wheel 203 and the cross bar 304 and the conveyor belt 103, and thus adjust the lifting height of the lifting rack 3, making the detection effect of the detection device better.

[0044] At present, the weight used is generally a rubber hammer, and the mass of the weight used is different according to the specifications of the ceramic tile body. The specifications of ceramic tiles are regulated by national standards. The larger the specification, the larger the size and the thicker the thickness, and the corresponding impact force that can be borne also increases. During the detection, the weight of the weight is adjusted according to the standard bearing force, that is, adjusted according to the production batch.

[0045] In addition, the mass of the weight can also be constant. At this time, high-pressure air is used to push the weight to rise, and the magnitude of the impact force is consistent with the pushing air pressure, that is, the higher it rises, the greater the impact force generated when it falls. Generally, the impact force is controlled at 900 - 1100N, which needs to be adjusted according to the specifications of the brick body; this pneumatic structure is easier to achieve automatic control. From the perspective of data collection, a data collection sensor can be set on the rubber hammer to count on-site data such as the workload and the fluctuation of the impact force; the display can be set on the support frame, which is convenient for on-site personnel to monitor.

[0046] The above are only the embodiments of the present utility model, and common knowledge such as the specific structures and characteristics known in the solutions is not described in detail herein. For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model. Any reference signs in the claims should not be construed as limiting the claimed rights involved.
