Description

Technical Field

[0001] This utility model relates to the field of appearance quality inspection technology for glazed bricks, and in particular to a measuring device for measuring the roller marks and collapse depth of glazed bricks. Background Technology

[0002] Polished glazed tiles account for over 90% of the domestic ceramic market. Currently, the surface of polished glazed tiles commonly exhibits uneven roller marks at the front and rear ends, 5-20cm from the edge, along the kiln exit direction, as well as sunken edges, affecting the surface flatness of the product. When the roller marks and sunken edges are too deep, they directly affect the laying and decorative effect of the polished glazed tiles. To improve the quality of ceramic tile products, enhance consumer satisfaction, and promote high-quality development of the consumer market, the measurement methods for roller mark depth and sunken edge depth have become important means of evaluating the appearance quality of polished glazed tile products.

[0003] Currently, the measurement of roller marks and edge collapse depth in glazed bricks mainly relies on visual inspection and traditional tools. Under certain angles and lighting conditions, inspectors roughly determine the position of the roller marks and use feeler gauges to measure the depth of the roller marks and edge collapse. Multiple measurements are taken and the maximum value is used. However, feeler gauge measurement has the disadvantages of low accuracy, complicated operation, and low efficiency, which affects the accuracy of roller mark and edge collapse depth measurement.

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this utility model.

[0034] like Figure 1 and Figure 2 As shown, this utility model provides a measuring device for measuring the depth of roller marks and edge collapse of glazed bricks, including at least three digital dial indicators 1, a support base 2, and a reference plate 3; the support base 2 is a cuboid structure, and the support base 2 has multiple reserved through holes 21 extending through the upper and lower surfaces of the support base 2 along its length; the digital dial indicators 1 are installed in the reserved through holes 21 by a fixing mechanism, the fixing mechanism including a pin 22 inserted into the reserved through hole 21, the digital dial indicator 1 and the pin 22 are plugged into each other, and the upper end of the pin 22 is fixed by a knob clamping cap 23; the reference plate 3 is used to calibrate the digital dial indicators 1.

[0035] Three digital dial indicators 1 are installed in the reserved through holes 21 by a fixing mechanism, which includes a pin 22 and a knob clamping cap 23. When fixing the digital dial indicator 1, the pin 22 is inserted into the reserved through hole 21 from top to bottom. Then, the knob clamping cap 23 is fastened onto the pin 22 from top to bottom. Next, the measuring end of the digital dial indicator 1 is inserted into the pin 22 from top to bottom. Finally, the digital dial indicator 1 is fixed by tightening the knob clamping cap 23. After installation, the measuring end (i.e., the measuring probe) of the digital dial indicator 1 can make perpendicular contact with the ceramic tile surface. The reference plate 3 is a flat steel plate used to calibrate the digital dial indicator 1. After calibration, it can be used to measure roller marks and edge collapse depth.

[0036] like Figure 2As shown, furthermore, a groove 24 for easy gripping is provided between two adjacent reserved through holes 21. Furthermore, the surface of the knob clamp cap 23 is provided with anti-slip texture. Furthermore, the pin 22 and the knob clamp cap 23 are connected by threads.

[0037] A groove 24 is provided on the support base 2. The depth and width of the groove 24 are ergonomically designed to facilitate the operator's hand movement or adjustment of the device, improving operational convenience and comfort. The anti-slip texture allows the operator to easily tighten or loosen the clamping cap even in wet or slippery environments, further enhancing operational ease. The pin 22 is made of wear-resistant, high-strength stainless steel, possessing excellent rigidity and durability, ensuring the fixed stability of the digital dial indicator 1, thereby reducing measurement errors.

[0038] Furthermore, the multiple reserved through holes 21 are arranged at equal intervals.

[0039] Furthermore, the digital dial indicator 1 is electronic, with a graduation value of 0.01 mm.

[0040] Furthermore, the support base 2 has a length of 200mm, a width of 19.20mm, and a maximum thickness of 12mm.

[0041] Furthermore, the support base 2 is made of stainless steel.

[0042] The support base 2 is made of high-hardness, high-wear-resistant stainless steel, which not only ensures good performance but also has the advantages of being lightweight and easy to carry.

[0043] The method of using the measuring device for measuring the roller marks and collapse depth of glazed bricks provided by this utility model is as follows:

[0044] (1) First, install and fix the measuring device: insert a pin 22 into each reserved through hole 21, and connect the upper end of the pin 22 to the knob clamping cap 23 through the thread. Insert the detection end of the digital dial indicator 1 into the pin 22 from top to bottom, and then lock the digital dial indicator 1 onto the support base 2 by rotating the knob clamping cap 23.

[0045] (2) Calibrate the digital dial indicator 1: Place the reference plate 3 on a horizontal surface, and then place the installed digital dial indicator 1 and the support base 2 on the reference plate 3 so that the detection end of the digital dial indicator 1 contacts the reference plate 3 and is zeroed.

[0046] (3) Measurement: Place the glazed tile 4 to be tested on a horizontal surface, adjust the measuring device so that the detection end of each digital dial indicator 1 is in contact with the area to be tested, and then read the data through the digital dial indicator 1 and record the depth value of each point.

[0047] In step (3), when measuring the roller mark and the depth of the collapsed edge, the roller mark of the glazed brick generally appears at the front and rear ends of the glazed brick in the direction of exiting the kiln, 5-20cm from the edge. However, the temperature of the glazed brick immediately after exiting the kiln is too high to measure, so it is usually necessary to wait until the glazed brick cools down to room temperature before it can be tested. Since there are a large number of glazed bricks in mass production, and it is difficult to distinguish the direction of exiting the kiln after cooling, it is necessary to measure all four sides of the glazed brick when testing the roller mark, and take the maximum value as the measurement result of the roller mark.

[0048] like Figure 3 As shown, before the measurement in step (3), four parallel lines 5 need to be drawn on the brick surface. The distances of the four parallel lines 5 from top to bottom to the edge of the glazed brick are 0.125 times, 0.375 times, 0.625 times, and 0.875 times the side length, respectively. The distances from the beginning and end of each parallel line 5 are taken at 300mm (i.e., Figure 3 The part of the parallel line 5 located in the shaded area is taken as the line segment to be tested 6. A total of eight line segments 6 are recorded, and the flatness of each line segment is measured.

[0049] During measurement, the length direction of the support base 2 should be parallel to the line segment 6 to be measured, and the detection end of the digital dial indicator 1 should be in contact with the line segment 6 to be measured. Then, move it left and right along the line segment 6 to measure. The above is the operation process for measuring one side. The other three sides are measured in the same way. After measurement, the maximum value of the depth of each line segment 6 to be measured is taken as the measurement result of the roller mark and the collapsed edge depth.

[0050] It should be noted that during use, collisions between the measuring end of the digital dial indicator 1 and hard objects should be avoided as much as possible to prevent affecting its accuracy; the device should be cleaned promptly after use, especially the groove 24 of the support base 2, to extend the service life of the device; the digital dial indicator 1 should be calibrated regularly to ensure the accuracy of the measurement results.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
