Description

A ruler for measuring the thickness of ceramsite boards Technical Field

[0001] This utility model relates to the field of measuring tools, specifically to a ruler for measuring the thickness of ceramsite boards. Background Technology

[0002] Expanded clay slabs are formed using a vibration pressing method. When forming a single slab, a pallet made of wood, fiber, or other materials serves as the bottom support structure. After repeated production cycles, the pallet develops unevenness, leading to dimensional deviations in the thickness of the produced expanded clay slabs. Vernier calipers cannot measure expanded clay slabs with pallets, and multi-point measurements with a ruler are inefficient and prone to error. Furthermore, fully automated expanded clay slab production lines have high production efficiency, and existing measuring tools cannot guarantee that production personnel can measure each formed slab at multiple points individually. To save on curing area, the expanded clay slabs are stacked in multiple layers after pressing, making it even more difficult to measure the thickness of the stacked slabs with a ruler.

[0003] Based on the current production situation, the thickness of the ceramsite boards formed on the production line can only be sampled and tested at a low frequency. Only after the ceramsite boards have completed their curing period (7-14 days) and have been removed from the pallet can the thickness of the cured ceramsite boards be measured at a high frequency using vernier calipers. At that time, the measurement workload is huge, and the feedback of the thickness measurement results is delayed (7-14 days), which may result in the production of a large number of ceramsite boards that do not meet the thickness deviation requirements. Summary of the Invention

[0004] This utility model aims to solve at least one of the above-mentioned technical problems and discloses a ruler for measuring the thickness of ceramsite boards. The calipers on the ruler can measure the deviation thickness of the ceramsite boards, and the scale end on the ruler can accurately measure the thickness of the ceramsite boards. This allows the ruler to measure the shaped ceramsite boards during the production process, after stacking, and in the curing area. It has low requirements for the measurement environment, is easy to implement, and improves measurement efficiency.

[0005] This utility model is achieved through the following technical solution:

[0006] A ruler for measuring the thickness of expanded clay slabs, comprising:

[0007] The base has a section on top for mounting the minimum deviation thickness caliper, the maximum deviation thickness caliper, and the graduation end.

[0008] The scale end, located on the first side of the base and with scale markings on top, is used to measure the thickness of the ceramsite board;

[0009] The minimum deviation thickness caliper is located on the second side of base 1 and is used to measure the lower limit of the thickness of the ceramsite board;

[0010] The maximum deviation thickness caliper is located between the minimum deviation thickness caliper and the scale end, and is used to measure the upper limit of the thickness of the ceramsite board;

[0011] Among them, the heights of the calipers with the smallest deviation thickness, the calipers with the largest deviation thickness, and the scale end increase in a step-like manner.

[0012] As a further improvement, the base and the minimum deviation thickness caliper, maximum deviation thickness caliper and scale end set on it are integrated into one structure.

[0013] As a further improvement, the base is equipped with a removable minimum thickness caliper, a maximum thickness caliper, and a scale end.

[0014] As a further improvement, the base is a groove with an opening in the middle. The bottom of the minimum deviation thickness caliper, the maximum deviation thickness caliper, and the scale end are used to insert into the opening in the middle of the groove. After being inserted into the groove, the bottom of the base, the minimum deviation thickness caliper, the maximum deviation thickness caliper, and the scale end are flush.

[0015] As a further improvement, the base has a limiting part on one side and a snap-fit ​​part on the other side.

[0016] As a further improvement, the limiting part can be a limiting plate set in the middle or limiting posts set on both sides.

[0017] As a further improvement, the scale is made of stainless steel.

[0018] As a further improvement, the maximum scale value of the scale end is H, the maximum scale value of the thickness caliper with the minimum deviation is H2, and the maximum scale value of the thickness caliper with the maximum deviation is H1. Then, H > H1 > H2. The lower limit of the production thickness of the ceramsite board is Tmin, and the upper limit of the production thickness of the ceramsite board is Tmax. Then, H1 = Tmin and H2 = Tmax.

[0019] As a further improvement, the accuracy of the scale end is 1mm, the smallest scale is 0mm, and the largest scale value is Tmax+5mm.

[0020] As a further improvement, the maximum scale value H2 of the thickness caliper with the smallest deviation is 48mm, the maximum scale value H1 of the thickness caliper with the largest deviation is 50mm, and the maximum scale value at the end of the scale is 55mm.

[0021] Compared with existing technologies, the scale for measuring the thickness of ceramsite boards described in this utility model has the following advantages:

[0022] (1) The caliper for measuring the thickness of the ceramsite board described in this utility model can measure the shaped ceramsite board in the production process, after stacking, and in the curing area in two ways. One method is that the minimum deviation thickness caliper and the maximum deviation thickness caliper can measure the ceramsite board by measuring the deviation thickness.

[0037] A ruler for measuring the thickness of expanded clay slabs, as shown in Figures 1 to 6, includes...

[0038] Base 1, with a minimum deviation thickness caliper 2, a maximum deviation thickness caliper 3, and a scale end 4 on top of base 1;

[0039] The scale end 4 is located on the first side of the base 1, and has a scale on top for measuring the thickness of the ceramsite board;

[0040] The minimum deviation thickness caliper 2 is located on the second side of the base 1 and is used to measure the lower limit of the thickness of the ceramsite board;

[0041] The maximum deviation thickness caliper 3 is located between the minimum deviation thickness caliper 2 and the scale end 4, and is used to measure the upper limit of the thickness of the ceramsite board;

[0042] Among them, the heights of the minimum deviation thickness caliper 2, the maximum deviation thickness caliper 3, and the scale end 4 increase in a step-like manner.

[0043] The scale designed in this invention allows for the measurement of shaped ceramsite slabs during production, after stacking, and in the curing area using two methods. One method involves using minimum deviation thickness calipers 2 and maximum deviation thickness calipers 3 to measure the ceramsite slabs based on thickness deviation. The other method involves precisely measuring the thickness of the ceramsite slabs using the graduated end 4. This effectively prevents defective products from flowing into the next process. Because of its simple structure and easy operation, this scale allows production personnel to quickly inspect the thickness of the ceramsite slabs, significantly reducing measurement time and improving efficiency.

[0044] In one embodiment of this utility model, the base 1 and the minimum deviation thickness caliper 2, maximum deviation thickness caliper 3 and scale end 4 above it are an integral structure, which facilitates injection molding and greatly improves production efficiency.

[0045] In another embodiment of this utility model, the base 1 has a detachable minimum thickness caliper 2, a maximum thickness caliper 3, and a scale end 4. When it is necessary to measure ceramsite boards of different thicknesses, it is not necessary to replace the entire scale; only the minimum thickness caliper 2, the maximum thickness caliper 3, and the scale end 4 with different scale values ​​need to be replaced.

[0046] In one embodiment, to ensure the accuracy of the scale, the base 1 is a groove with an opening in the middle. The lowest part of the minimum deviation thickness caliper 2, the maximum deviation thickness caliper 3, and the scale end 4 are used to insert into the opening in the middle of the groove. After being inserted into the groove, the bottoms of the base 1, the minimum deviation thickness caliper 2, the maximum deviation thickness caliper 3, and the scale end 4 are flush, so that the structure does not affect the accuracy of each scale mark.

[0047] In one embodiment, in order to ensure the fit between the base 1 and the minimum deviation thickness caliper 2, the maximum deviation thickness caliper 3 and the scale end 4 after connection, a limiting part is provided on one side of the base 1 and a snap-fit ​​part is provided on the other side.

[0048] Preferably, the limiting part is a limiting plate set in the middle or limiting posts set on both sides.

[0049] The connection process between the minimum deviation thickness caliper 2, the maximum deviation thickness caliper 3, the scale end 4, and the base 1 is as follows:

[0050] First, slide the minimum deviation thickness caliper 2 into the base 1 along the slide groove until it abuts against the limiting part. The limiting part can prevent the minimum deviation thickness caliper 2 from sliding out of the slide groove. Then, slide the maximum deviation thickness caliper 3 and the scale end 4 into the base 1 along the slide groove in sequence. Then, the scale end 4 is locked by the locking part. At this time, the minimum deviation thickness caliper 2, the maximum deviation thickness caliper 3 and the scale end 4 are pressed tightly together, which helps to ensure the accuracy of the scale measurement.

[0051] In one or more embodiments, the ruler used for measuring the thickness of the ceramsite board is made of stainless steel.

[0052] For ease of description, in this utility model, the maximum scale value of the scale end 4 is set to H, the maximum scale value of the minimum deviation thickness caliper 2 is H2, and the maximum scale value of the maximum deviation thickness caliper 3 is H1. Therefore, H > H1 > H2. The lower limit of the production thickness of the ceramsite board is Tmin, and the upper limit of the production thickness of the ceramsite board is Tmax. Therefore, H1 = Tmin, H2 = Tmax.

[0053] The accuracy of scale end 4 is 1mm, the minimum scale division is 0mm, and the maximum scale division value is Tmax+5mm. In addition to re-measuring the thickness of the ceramsite board based on the thickness deviation judgment result using scale end 4, the precise thickness of the ceramsite board on the production line or the top ceramsite board after stacking can be measured in real time as needed during the production process.

[0054] This measuring scale can be used to measure and determine the thickness of ceramsite boards at various stages, including during production, after stacking, and after transportation to the curing area. The measurement principle of the ceramsite board thickness measuring scale is as follows:

[0055] Place the expanded clay slab 6 on the tray 7, stacking them layer by layer. Before the test begins, ensure that the lower surface of the base 1 is in contact with the upper surface of the tray 7 to be tested, and that the minimum deviation thickness caliper 2, the maximum deviation thickness caliper 3, and the scale end 4 are aligned with the thickness direction of the expanded clay slab 6 to be measured. During measurement, if the minimum deviation thickness caliper 2 can be inserted into the space between the upper surface of the tray 7 to be measured and the lower surface of the adjacent upper tray, then the thickness of the expanded clay slab at measurement point 5 meets the minimum deviation requirement. If the maximum deviation thickness caliper 2 cannot be inserted into the space between the upper surface of the bottom tray 7 to be measured and the lower surface of the adjacent upper tray, then the thickness of the expanded clay slab at measurement point 5 meets the maximum deviation requirement. A total of 12 measurement points are set, as shown in measurement point 5 in Figure 6. The 12 measurement points are located at the midpoints of the four sides of the expanded clay slab, 100 mm inward from the endpoints. When measuring the thickness deviation of the expanded clay slab, the minimum and maximum deviations need to be determined for all 12 measurement points 5. If all measurement points meet the thickness deviation requirements, the thickness of the expanded clay slab is qualified. If any of the measurement points 5 do not meet the thickness deviation standard, the thickness of the expanded clay slab is accurately measured using the scale end 4 of a ruler for the measurement points 5 that do not meet the standard. The measurement data is then promptly fed back to the expanded clay slab forming area, and the equipment and forming parameters are adjusted accordingly.

[0056] In one embodiment, the maximum scale value H2 of the minimum deviation thickness caliper 2 is 48mm, the maximum scale value H1 of the maximum deviation thickness caliper 3 is 50mm, and the maximum scale value of the scale end 4 is 50+5=55mm. The steps for using this utility model's measuring scale in this production site are as follows:

[0057] As shown in Figure 4, for the molded ceramsite boards in the production process, after stacking, and in the curing area, the minimum deviation thickness is first determined. At the specific measurement point 5, the lower surface of the base 1 is placed against the upper surface of the bottom tray 7 of the ceramsite board 6 to be measured, ensuring that the minimum deviation thickness caliper 2, the maximum deviation thickness caliper 3, and the scale end 4 are aligned with the thickness direction of the ceramsite board 6 to be measured. An attempt is made to insert the minimum deviation thickness caliper 2 into the space between the upper surface of the bottom tray 7 of the ceramsite board to be measured and the lower surface of the adjacent upper tray. If it can be inserted, the thickness of the ceramsite board at measurement point 5 is greater than 48mm, meeting the minimum deviation requirement. Then, the maximum deviation thickness is determined by attempting to insert the maximum deviation thickness caliper 3 into the space between the upper surface of the bottom tray 7 of the ceramsite board to be measured and the lower surface of the adjacent upper tray 7. If it cannot be inserted, the thickness of the ceramsite board at that point is less than 50mm, meeting the maximum deviation requirement.

[0058] As shown in Figure 6, there are 12 measurement points for thickness deviation judgment, located at the midpoint of the four sides of the ceramsite board and 100mm inward from the end point.

[0059] As shown in Figure 5, for measurement points 5 with a thickness of less than 48mm or greater than 50mm, the upper stacked ceramsite board 6 and its tray 7 are removed, and the thickness of the ceramsite board is accurately measured using the scale end 4 of the ruler, and the measurement data are statistically analyzed.

[0060] The measurement data is promptly fed back to the ceramsite board forming area, and adjustments are made to the equipment and forming parameters accordingly.

[0061] In addition to re-measuring the thickness of the ceramsite board by using the scale end 4 of the ruler to determine the thickness deviation, the precise thickness of the ceramsite board on the production line or the top ceramsite board after stacking can be measured in real time as needed during the production process.

[0062] In summary, the scale designed in this invention can measure the thickness of the formed ceramsite boards during production, after stacking, and in the curing area using two methods. One method involves using the minimum deviation thickness caliper 2 and the maximum deviation thickness caliper 3 to measure the thickness deviation. The other method involves using the scale end 4 to accurately measure the thickness of the ceramsite board. This effectively prevents defective products from flowing into the next process. Because of its simple structure and easy operation, this scale allows production personnel to quickly check the thickness of the ceramsite boards, greatly reducing measurement time and improving efficiency. Furthermore, this scale can be applied in various production stages, making it more versatile. Especially when used at the beginning of the production process, it allows for early detection of problems, effectively reducing raw material waste, improving product consistency, and reducing the workload of subsequent ceramsite board quality inspection.

[0063] It should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
