[0003] 1. Ensure product quality: By testing the thickness of the high-elastic waterproof polyurethane film, it can be ensured that the product meets the design requirements and standard regulations, thereby ensuring the quality and performance of the product.

[0004] 2. Control construction quality: During the construction process in the fields of construction, water conservancy, transportation, etc., testing the thickness of the polyurethane film can effectively control the construction quality and ensure the waterproof effect.

[0005] 3. Improve the durability of the project: Polyurethane film has the advantages of high elasticity, aging resistance, and tensile resistance. Testing its thickness can ensure that the film has a long life during the use of the project and improve the durability of the project.

[0006] 4. Save materials and energy: By testing the thickness of the polyurethane film, it can ensure that the material is used in a reasonable amount, avoid excessive use and waste, and thus save resources and costs.

[0007] 5. Ensure project safety: In important engineering fields, such as tunnels, subways, bridges, etc., testing the thickness of polyurethane waterproof film can ensure the waterproof effect of the project, prevent leakage and accidents, and ensure project safety.

[0009] Existing film thickness detection methods mainly include micrometer measurement method and slicing method. The micrometer measurement method uses a micrometer to directly measure the thickness of the polyurethane film. This is a simple and direct method, but it may be affected by the operating level of the measurement personnel and the surface roughness of the polyurethane film. The slicing method cuts the polyurethane film into thin slices and then observes the thickness of the slices under a microscope to calculate the actual thickness of the film. This method has high accuracy, but the operation process is more complicated and will cause a certain degree of damage to the polyurethane film. Utility Model Content

[0023] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0024] See also Figures 1 to 3 , the utility model embodiment includes:

[0025] A thickness detection device for a high-elastic waterproof polyurethane film comprises a detection table 1, on which a plurality of rollers 2 are mounted, the tops of the plurality of rollers 2 forming a table surface for supporting a film 3, and an automatic detection structure mounted on the detection table 1, which can measure the thickness of the film 3 during transmission, and warn of defective products, thereby reducing the influence of human factors.

[0026] The automatic detection structure includes a pressing structure for pressing the surface of the film 3 and a measuring structure for measuring the thickness.

[0027] The clamping structure includes two brackets 5 and a pressing roller 4 . The two brackets 5 are symmetrically installed on both sides of the detection platform 1 . The brackets 5 are used for installing the pressing roller 4 .

[0028] The pressing roller 4 is horizontally installed between the two brackets 5 through lifting structures respectively arranged on the two brackets 5. The pressing roller 4 is used to press the film 3 conveyed on the detection platform 1. When the thickness of the film 3 changes, the pressing roller 4 will also move up and down accordingly.

[0029] The lifting structure includes a slider 7 and a slide groove 8. The slider 7 is slidably connected to the slide groove 8, and the slide groove 8 is used for the slider 7 to move up and down.

[0030] The pressure roller 4 is rotatably connected to the cross bar 6 fixed between the two sliders 7. The up and down movement of the pressure roller 4 drives the up and down movement of the slider 7. The slider 7 cooperates with the slide groove 8, so that the pressure roller 4 can maintain horizontal up and down movement. Therefore, if the film 3 has a slight uneven thickness in the longitudinal position, it will cause the movement of the pressure roller 4, making the detection more accurate.

[0031] A pressure spring 9 is installed between the top of the slider 7 and the top of the slide groove 8. The pressure spring 9 applies pressure to the slider 7, so that the pressure roller 4 is always in contact with the upper surface of the film 3, avoiding the pressure roller 4 from jumping due to too fast transmission of the film 3 and too large difference in thickness of the film 3, thereby affecting the measurement result.

[0032] When the slide block 7 reaches the bottom of the slide groove 8 , the pressure spring 9 is in a stationary state.

[0033] The measuring structure includes a laser ranging sensor 10 and a laser reflecting plate 11. The laser emitter is installed at the bottom of the slide groove 8, and the laser reflecting plate 11 is installed at the bottom of the slider 7. The laser ranging sensor 10 emits a laser beam to the laser reflecting plate 11, and measures the time it takes for the laser reflecting plate 11 to reflect the laser back to calculate the distance.

[0034] The laser reflection plate 11 can improve measurement accuracy and reliability.

[0035] Laser ranging has the advantages of high precision, high efficiency and strong anti-interference ability.

[0036] The laser distance sensor 10 is connected to an external processing device through an electric wire, and the thickness change measured by the laser distance sensor 10 is counted by the external processing device. When the thickness exceeds a preset range, an alarm is issued to remind the operator that the product is unqualified.

[0037] Different from the prior art, the utility model is a thickness detection device for high-elasticity waterproof polyurethane film. The device adopts an automatic detection structure, can measure the thickness during the film transmission process, and warn of defective products, reducing the influence of human factors.
