Description

Technical Field

[0001] This application relates to roll material processing technology, and more particularly to an embossing depth measuring device. Background Technology

[0002] Waterproof membranes are waterproofing materials used in building and engineering projects. They prevent moisture from penetrating into the building structure, helping to protect the integrity of the building and extend its service life. Some waterproof membranes, such as bitumen waterproof membranes and modified bitumen waterproof membranes, are generally made from a base material, such as polyester felt or fiberglass felt, through pre-impregnation with oil and coating.

[0003] In the production process of this type of waterproof membrane, after the base material is pre-impregnated with oil and coated with material, it needs to be cooled with cooling water. However, after the waterproof membrane is cooled with cooling water, the surface moisture is not easy to dry, which will result in poor appearance quality of the final product after subsequent surface treatment.

[0004] There are two common surface treatment methods. One is to cover the waterproof membrane with a layer of polyethylene film to obtain a PE film product. For PE film products, if the waterproof membrane is not dried before applying the PE film, it will result in more air bubbles between the PE film and the coating material. The other is to sprinkle a layer of fine sand or mineral particles on the surface of the waterproof membrane to obtain a sanded surface product. For sanded surface products, if the waterproof membrane is not dried before sprinkling the fine sand or mineral particles, it will result in more loose sand on the sanded surface.

[0005] To improve the appearance of waterproof membranes, a common practice is to emboss them. Embossing removes air bubbles and improves the membrane's appearance. The depth of embossing significantly affects the performance of the waterproof membrane; therefore, it is generally necessary to measure the embossing depth after embossing.

[0006] Currently, when sampling and testing waterproof membranes from finished products, a thickness gauge is usually used manually. The thickness gauge is used to press the surface of the waterproof membrane, and the thickness of different parts of the waterproof membrane is obtained by visual reading, thus obtaining the embossing depth. However, this method requires precise control of the pressure of the thickness gauge on the waterproof membrane, which results in a large error. Utility Model Content

[0007] This application provides an embossing depth measuring device to solve the problem of large errors when measuring the embossing depth of existing waterproof membranes using a thickness gauge.

[0016] In some possible implementations, the bracket is provided with a first limiting groove, the support column is inserted into the first limiting groove, and the first driving assembly includes:

[0017] Multiple transmission teeth are arranged sequentially and at intervals on the support column along the extension direction of the support column;

[0018] A drive gear is rotatably connected to the bracket and meshes with the transmission gear.

[0019] A first locking member is threadedly connected to the bracket, and the first locking member is configured such that when the bracket is driven by the drive gear to move along the support column to a preset position, one end extends into the first limiting groove and abuts against the support column to limit the relative position of the bracket and the support column.

[0020] In some possible implementations, the bracket is provided with a mounting groove communicating with the first limiting groove, the drive gear is located in the mounting groove, and the drive gear extends into the first limiting groove and meshes with the transmission gear.

[0021] In some possible implementations, the first drive assembly further includes a rotating shaft rotatably connected to the bracket, a drive gear connected to the rotating shaft, and at least one end of the rotating shaft extending outside the bracket and connected to an adjustment handle.

[0022] In some possible implementations, the support column is provided with a first limiting part, and a second limiting part is provided in the first limiting groove. One of the first limiting part and the second limiting part is a slot, and the other is a locking block that engages with the slot. The extending direction of the slot is the same as the extending direction of the support column.

[0023] In some possible implementations, the support further includes a base, and the adjustment structure further includes:

[0024] A support base is provided on the base, and the shelf is slidably connected to the support base;

[0025] A second drive assembly is disposed on the support base and is configured to drive the platform to move along the height direction of the support base.

[0026] In some possible implementations, the support base is provided with a guide rail, and the shelf is provided with a guide block that cooperates with the guide rail.

[0027] In some possible implementations, the second driving component includes:

[0028] A differential head is mounted on the support base, and the measuring rod of the differential head is used to push the platform to move along the height direction of the support base;

[0029] The second locking member is threadedly connected to the support base. The second locking member is configured such that after the micrometer head pushes the platform to move a preset distance, one end of the second locking member abuts against the platform to limit the relative position between the platform and the support base.

[0030] In some possible implementations, the second driving component further includes:

[0031] A connector, which is rotatably connected to the support base;

[0032] An elastic element is provided, with one end connected to the support base and the other end connected to the platform. The extension direction of the elastic element is the same as the movement direction of the platform. The elastic element is configured to drive the platform to move away from the laser rangefinder sensor through deformation.

[0033] A first adapter is connected to the connecting member and contacts the measuring rod of the micrometer head.

[0034] A second adapter is connected to the connector, and the angle between the second adapter and the first adapter is greater than 0° and less than or equal to 90°. The second adapter is configured to rotate with the first adapter and push the platform toward the laser rangefinder when the probe of the micrometer head pushes the first adapter to rotate.

[0035] The embossing depth measuring device provided in this application comprises a bracket, a laser rangefinder sensor, a platform, and an adjustment structure. The bracket supports the laser rangefinder sensor and the platform. The adjustment structure can move one of the laser rangefinder sensor and the platform to change the distance between them, preventing the distance from exceeding the measurement distance of the laser rangefinder sensor. When sampling and testing waterproof membrane, the object to be measured is placed on the platform with its sub-image facing the laser rangefinder sensor. The laser sensor then obtains the distance between the concave part and the highest point of the convex part of the embossed surface, thus obtaining the embossing depth. The measurement result can be directly displayed digitally. Compared to manual handheld thickness gauge testing, the laser rangefinder sensor does not compress the waterproof membrane, avoiding measurement errors caused by inconsistent compression force. Furthermore, it eliminates the need for manual reading, avoiding reading errors and effectively improving the accuracy of embossing depth measurement of waterproof membrane.

[0049] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0050] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0051] For some waterproof membranes, such as asphalt waterproof membranes, the base material needs to be cooled with cooling water after pre-impregnation with oil and coating. However, after cooling with water, the surface moisture of the asphalt waterproof membrane is not easy to dry, which will affect the appearance quality of the final product. For PE film products, this will result in more air bubbles between the PE film and the coating. For sand-surface products, this will result in more loose sand on the sand-spreading surface.

[0052] To address this, adding an embossing roller device to the production line to emboss the roll material can help eliminate air bubbles and improve its appearance quality. Embossing also enhances the roll material's aesthetics and anti-counterfeiting capabilities. However, controlling the embossing depth is also crucial to the product quality of the waterproof roll material.

[0053] Currently, the embossing depth control of waterproof membranes is usually achieved by sampling finished products for testing using a manual thickness gauge. This equipment requires a high level of technical skill from the testing personnel. Because waterproof membranes have a certain degree of elasticity, and the thickness gauge has a certain weight, the weight of the gauge can significantly affect the measurement results when it presses against the surface of the waterproof membrane. Therefore, operators need to precisely control the pressure applied to the waterproof membrane and the reading time. Different personnel using the same equipment, or the same personnel using different equipment, may produce significantly different test results with large errors. This further increases the measurement error of the embossing depth of the waterproof membrane, greatly affecting the accuracy of product quality testing.

[0054] In response, this application provides an embossing depth measuring device, which is a measuring device unaffected by gravity. It mainly measures the embossing depth or thickness of roll material directly through a laser rangefinder sensor, which can solve the influence of human factors in the embossing depth measurement process, greatly improve the measurement accuracy, and the thickness measurement efficiency is also significantly improved compared to using a traditional thickness gauge. In addition, the samples are generally small during sampling tests, so the volume of the platform and support is not too large, and the laser rangefinder sensor is also small. Therefore, the entire measuring device is small in size, easy to carry, and convenient to use in different scenarios.

[0055] It is understood that the embossing depth measuring device provided in this application embodiment can be used not only to measure the embossing depth of objects with embossed surfaces, but also to measure the thickness of products without embossed surfaces.

[0056] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0057] In some embodiments, see Figure 1 As shown, the embossing depth measuring device includes a bracket 100, a laser rangefinder 200, a platform 300, and an adjustment structure.

[0058] Both the laser rangefinder 200 and the platform 300 are mounted on the bracket 100 and supported by the bracket 100. The adjustment structure is connected to at least one of the laser rangefinder 200 and the platform 300. The adjustment structure can drive at least one of the laser rangefinder 200 and the platform 300 to move along the height direction of the bracket 100 to adjust the distance between the laser rangefinder 200 and the platform 300.

[0059] The laser rangefinder 200 is a device that uses laser technology to measure distance. It can be classified according to the wavelength or type of laser light source used, such as infrared rangefinder, visible light rangefinder, and ultraviolet rangefinder. The specific type can be selected according to the actual situation.

[0060] Taking the laser rangefinder 200 as an example of an infrared rangefinder, it utilizes the principle that infrared light does not spread during propagation. When infrared light is emitted from the infrared rangefinder and is reflected back by a reflective object, it can calculate the distance between the reflective object and the infrared rangefinder based on the time from emission to reception and the propagation speed of the infrared light.

[0061] Specifically, when measuring the embossing depth of the roll material, the distance between the platform 300 and the laser rangefinder 200 is pre-adjusted. At this point, the distance between the platform 300 and the laser rangefinder 200 is determined. This distance can be determined directly during adjustment by pre-inputting the laser rangefinder 200, or after adjusting the position of the platform 300 and / or the laser rangefinder 200, the distance between the surface of the platform 300 and the laser rangefinder 200 is first measured using the laser rangefinder 200. After determining the initial distance between the laser rangefinder 200 and the platform 300, the object to be measured can be placed on the platform 300. Then, the distance between the object to be measured and the laser rangefinder 200 is measured using the laser rangefinder 200. The difference between this distance and the initial distance between the platform 300 and the laser rangefinder 200 is the thickness of the object to be measured.

[0062] After the waterproof membrane is embossed, it is generally necessary to measure the distance difference between the recessed areas and the highest points of the embossed areas on the embossed surface, i.e., as shown below. Figure 6 The embossing depth is indicated by d. At this point, by moving the roll sample so that different parts of it are below the laser rangefinder 200, the thickness difference of different parts of the roll can be calculated in the same way as described above, thus adapting to the measurement of the overall thickness and embossing depth of the waterproof roll.

[0063] Understandably, the laser rangefinder sensor 200 can be configured to display the thickness of the embossed recesses and the thickness of the highest point of the embossing, as well as the embossing depth, to improve ease of use.

[0064] Meanwhile, during measurement, the laser rangefinder 200 directly measures the thickness of the roll material using infrared light, without needing to compress the roll material. Therefore, it avoids the problem of large measurement errors caused by uneven compression. In addition, after measurement, the laser rangefinder 200 can directly display the measurement data without the need for manual interpretation and reading, which can avoid errors caused by manual reading and thus effectively improve the accuracy of detection.

[0065] Taking infrared ranging sensors as an example, their resolution can reach 0.001mm, which is 10 times higher than the resolution of conventional roll material thickness gauges. Furthermore, without the need for manual readings and adjustments to the pressure applied to the roll material by the thickness gauge, the detection efficiency can be improved by about 70%.

[0066] In some embodiments, see Figure 1 , Figure 2 and Figure 3 As shown, the bracket 100 includes a support column 110 that extends vertically, and the adjustment structure includes a bracket 410 and a first drive assembly 420.

[0067] One end of the bracket 410 is slidably connected to the support column 110, and the other end extends above the shelf 300. The laser range sensor 200 is located at the end of the bracket 410 away from the support column 110 and is supported by the bracket 410.

[0068] It is understandable that the laser rangefinder 200 can be directly fixed to the bracket 410 by common fixing methods such as bolts, as long as the laser rangefinder 200 does not shake during use. This embodiment does not impose any restrictions on this.

[0069] The first drive assembly 420 is connected to the bracket 410. The first drive assembly 420 can drive the bracket 410 to move along the height direction of the support 100, thereby adjusting the height of the platform 300 and changing the distance between the surface of the platform 300 and the laser range sensor 200 to meet the detection requirements.

[0070] For example, the first drive component 420 can be an electric cylinder. The output end of the electric cylinder is connected to the bracket 410 and can drive the bracket 410 to move up and down along the support column 110. The support column 110 mainly serves to limit the movement trajectory of the laser rangefinder 200. At this time, the bracket 410 can be limited by adding a slide rail or slide groove to the support column 110.

[0071] For example, the first drive assembly 420 includes a drive gear 422 and a plurality of transmission teeth 421. The bracket 410 is provided with a first limiting groove 411, and the support column 110 is inserted into the first limiting groove 411, so that the bracket 410 can move along the support column 110.

[0072] Multiple transmission teeth 421 are arranged sequentially at intervals along the vertical direction on the support column 110. The drive gear 422 meshes with the transmission teeth 421 and is rotatably connected to the bracket 410. When it is necessary to adjust the vertical position of the bracket 410, the drive gear 422 can be rotated directly, which will push the drive gear 422 and the bracket 410 to move up and down synchronously along the support column 110. At this time, the rotation of the drive gear 422 can be done manually or by adding a micro motor.

[0073] Furthermore, a mounting groove communicating with the first limiting groove 411 can be opened on the bracket 410, and the drive gear 422 can be placed in the mounting groove. At the same time, part of the drive gear 422 extends into the first limiting groove 411 through the connection between the mounting groove and the first limiting groove 411 to mesh with the transmission gear 421.

[0074] This design ensures that the engagement between the drive gear 422 and the transmission gear 421 is not affected, while also preventing the drive gear 422 from being directly exposed, thus providing better protection for the drive gear 422.

[0075] Furthermore, the first drive assembly 420 also includes a rotating shaft rotatably connected to the bracket 410, a drive gear 422 connected to the rotating shaft, and at least one end of the rotating shaft extends outside the bracket 410 and is connected to an adjustment handle 500.

[0076] For example, the length of the rotating shaft is greater than the width of the bracket 410. The rotating shaft passes directly through the first limiting groove 411 and extends to the outside of the bracket 410 at both ends. Adjusting handles 500 are installed at both ends of the rotating shaft. The rotating shaft can be rotated by holding the adjusting handles 500. The drive gear 422 is connected to the rotating shaft by common methods such as key connection, so that the drive gear 422 can rotate synchronously with the rotating shaft, thereby changing the height of the bracket 410 in the vertical direction.

[0077] Understandably, the adjustment handle 500 can be an adjustment wheel. The adjustment wheel is easy to hold and rotate, and has no sharp points, which can prevent scratching the user or other objects.

[0078] In some embodiments, in order to effectively fix the bracket 410 after it has been positioned, the first drive assembly 420 further includes a first locking member 423, which is threadedly connected to the bracket 410.

[0079] Specifically, a threaded hole is provided on the groove wall of the first limiting groove 411, and the first locking member 423 can be a locking nut. The first locking member 423 is threadedly connected to the threaded hole. When the bracket 410 is driven by the drive gear 422 to move along the support column 110 to the preset position, the locking nut can be turned at one end outside the bracket 410, so that the other end of the locking nut extends into the first limiting groove 411 and abuts against the support column 110, thereby limiting the relative position of the bracket 410 and the support column 110, thus preventing the bracket 410 from shifting during use.

[0080] In some embodiments, a first limiting part 111 is provided on the support column 110, and a second limiting part 413 is provided in the first limiting groove 411. One of the first limiting part 111 and the second limiting part 413 is a slot, and the other is a block that engages with the slot. The extending direction of the slot is the same as the extending direction of the support column 110.

[0081] For example, one or more arc-shaped slots are provided on the support column 110, and an arc-shaped block corresponding to the slot is provided in the first limiting groove 411. During connection, the bracket 410 is raised above the support column 110 so that the first limiting groove 411 is aligned with the support column 110 and the positions of the block and the slot are opposite. Then the bracket 410 is moved downward so that the support column 110 is inserted into the first limiting groove 411 and the block is inserted into the corresponding slot.

[0082] For example, one or more locking blocks can be added to the support column 110, and additional locking slots corresponding to the locking blocks can be opened on the groove wall of the first limiting groove 411.

[0083] Furthermore, an outwardly protruding support portion 112 can be added to the support column 110. The first limiting groove 411 includes a transition area that cooperates with the support portion 112. The shape of the transition area is adapted to the shape of the support portion 112. The mounting groove communicates with the transition area of ​​the first limiting groove 411. The drive gear 422 extends into the transition area and meshes with the transmission gear 421.

[0084] In order to better restrict the relative position of the bracket 410 and the support column 110 and prevent the bracket 410 from rotating, the support part 112 can be trapezoidal, that is, its width gradually decreases along the direction close to the support column 110. This can help restrict the relative position between the bracket 410 and the support column 110 bracket 100, reduce the force on the first locking member 423, and help extend its service life.

[0085] In addition, to reduce the weight of the bracket 410, a weight-reducing hole 412 can be provided between the first limiting groove 411 on the bracket 410 and the part of the bracket 410 used to connect the laser sensor.

[0086] In some embodiments, see Figure 1 , Figure 4 and Figure 5 As shown, the bracket 100 also includes a base 120, and the support column 110 is fixed on the base 120. The adjustment structure also includes a support seat 430 and a second drive assembly.

[0087] The support base 430 is fixed on the base 120 and can be located at both ends of the base 120, respectively, along with the support column 110, to save space. The shelf 300 is slidably connected to the support base 430, which means it can move up and down along the support base 430 to change the position of the shelf 300 in the vertical direction.

[0088] The second drive assembly is mounted on the support base 430 and connected to the platform 300. The platform 300 is driven to move along the height direction of the support base 430 through the second drive assembly, thereby adjusting the height of the platform 300. This allows the height of the platform 300 to be adjusted according to the actual situation, changing the distance between it and the laser rangefinder to match the testing requirements.

[0089] It is understood that the adjustment structure may include only one of the first drive component 420 or the second drive component, or it may include both. The specific configuration can be set according to the actual adjustment needs, and this embodiment does not limit it.

[0090] Furthermore, a guide rail is provided on the support base 430, and a guide block that cooperates with the guide rail is provided on the shelf 300.

[0091] Specifically, the support base 430 can be configured as an inverted T-shaped structure, including a base plate and a boss on the base plate. The base plate and the base 120 can be connected by common methods such as bolts. The shelf 300 includes a support plate and side plates. A side plate is provided on each of the opposite sides of the support plate, so that the side plate covers the outside of the boss. At this time, guide rails can be set on the boss and extended vertically. Depending on the actual situation, one, two or even more guide rails can be set, that is, guide rails can be set on one or two sides of the boss. Guide blocks are set on the corresponding side plates to improve the restriction effect on the movement trajectory of the shelf 300.

[0092] Among them, the guide rail can be a cross roller guide rail, and the rollers are placed in the raceway of the guide rail. The guide block is connected to the side plate and can move smoothly along the guide rail. Thus, the guide rail can not only restrict the movement direction of the side plate, but also withstand a large radial and axial load, effectively supporting the platform 300.

[0093] In some embodiments, the second drive assembly includes a micrometer head 441 and a second locking member 442. The micrometer head 441 is disposed on the support base 430, and the probe 4411 of the micrometer head 441 is used to push the stage 300 to move up and down in the vertical direction. The second locking member 442 is threadedly connected to the support base 430. After the micrometer head 441 initiates the movement of the stage 300 a preset distance, one end of the second locking member 442 abuts against the stage 300 to limit the relative position between the stage 300 and the support base 430.

[0094] Specifically, the second locking member 442 can be a locking nut. A strip hole 310 extending vertically can be opened on the side plate, and a threaded hole can be opened on the boss of the support base 430. The second locking member 442 passes through the strip hole 310 and is threadedly connected to the threaded hole. During adjustment, the second locking member 442 is turned outward so that the end of the second locking member 442 is not pressed against the side plate. The position of the shelf 300 can be adjusted by the micron head 441. After adjustment, the second locking member 442 is turned again so that the end of the second locking member 442 is pressed against the side plate, so that the side plate does not move relative to the boss.

[0095] The micrometer head 441 is an existing structure, which generally includes a fixed mounting sleeve, a bushing 4413, and movable measuring rods 4411, micrometer drums 4412, and fine-tuning knobs 4414. The mounting sleeve is fixedly connected to the support base 430. Both the bushing 4413 and the micrometer drum 4412 are equipped with scale lines. When the fine-tuning knob 4414 is rotated, the measuring rod 4411 will move along the mounting sleeve, and the micrometer drum 4412 will also rotate, thereby changing the scale value exposed on the bushing 4413. By simply reading the readings on the bushing 4413 and the micrometer drum 4412, the distance moved by the measuring rod 4411 can be determined, thereby determining the moving distance of the stage 300. The graduation of the micrometer head 441 is generally 0.01mm. Therefore, during use, the distance of the stage 300 can be finely adjusted through the micrometer head 441 to accurately control the measurement point.

[0096] During use, the measuring rod 4411 of the micrometer head 441 can extend vertically, so that the end of the measuring rod 4411 directly contacts the support plate or side plate of the platform 300, and the measuring rod 4411 directly pushes the platform 300 to move.

[0097] In order to reduce the pressure exerted by the stage 300 on the micrometer head 441, the measuring rod 4411 can also be extended in the horizontal direction. At this time, a special component is used to convert the lateral movement of the measuring rod 4411 into the vertical movement of the stage 300.

[0098] For example, the second drive assembly further includes a first adapter 444, a second adapter 445, and a connector 446. Both the first adapter 444 and the second adapter 445 are connected to the connector 446, which is located on one side of the boss and is rotatably connected to the boss. The angle between the second adapter 445 and the first adapter 444 is greater than 0° and less than or equal to 90°. When any one of the connector 446, the first adapter 444, and the second adapter 445 rotates, the other two will rotate synchronously.

[0099] The first adapter 444 and the second adapter 445 can be rods or plates, as long as they have a certain length and can be rotated to contact the measuring rod 4411 and the platform 300 respectively. The connecting member 446 can be a plate of any other structure of the disc, as long as it can effectively connect the first adapter 444 and the second adapter 445. This embodiment does not limit it.

[0100] Generally, the angle between the first adapter 444 and the second adapter 445 should be 90°. In use, the measuring rod 4411 contacts the first adapter 444. When the measuring rod 4411 moves away from the mounting sleeve, it will push the first adapter 444 and the connecting piece 446 of the second adapter 445 to rotate synchronously. At this time, the second adapter 445 will contact the support plate of the platform 300, pushing the support plate to move upward, thereby reducing the distance between the platform 300 and the laser rangefinder 200. To facilitate the contact between the second adapter 445 and the platform 300, a connector can be added to the bottom of the support plate. The connector extends towards the base 120. When the second adapter 445 pushes the platform 300 to move, the connector first contacts the side of the second adapter 445 away from the first adapter 444. Under the push of the second adapter 445, the platform 300 rises.

[0101] When it is necessary to lower the platform 300, rotate the fine adjustment knob 4414 to move the measuring rod 4411 toward the mounting sleeve. At this time, under the gravity drive of the platform 300, the first adapter 444 and the second adapter 445, the first adapter 444 and the second adapter 445 will rotate in opposite directions, and the platform 300 will gradually move downward to reset.

[0102] To facilitate the resetting of the platform 300, the second drive assembly also includes an elastic element 443. One end of the elastic element 443 is connected to the support base 430, and the other end is connected to the platform 300. The extension direction of the elastic element 443 is the same as the movement direction of the platform 300. The elastic element 443 drives the platform 300 to move away from the laser rangefinder 200 through deformation. That is, when the platform 300 is at its lowest height, the elastic element 443 is in a free state or a stretched state, so that when the platform 300 moves to any position, the elastic element 443 can maintain the tendency to pull the platform 300 down.

[0103] It is understood that the elastic element 443 can be a common structure such as a spring or a sheet, and one or more of them can be provided. Its two ends can be connected to the support plate and the bottom plate respectively, or they can be connected to the side plate and the bottom plate. This embodiment does not limit it.
