Description

Technical Field

[0001] The present invention relates to the technical field of thickness detection devices, and particularly relates to a thickness detection device for manufacturing waterproof coiled materials. Background Art

[0002] A waterproof coiled material is a material used for building waterproofing. The main function of the waterproof coiled material is to prevent water penetration and protect the building structure from water erosion. It is widely used in roofs, basements, bathrooms, pools, bridges, tunnels and other places.

[0003] During the production of existing waterproof coiled materials, spot checks need to be carried out on the coiled materials. When detecting the waterproof coiled materials, a part of the coiled material needs to be cut off and then the thickness is measured. The measurement of the thickness of the coiled material is generally divided into two types: mechanical measurement and laser measurement. In order to improve the detection efficiency, most use a laser detector to perform multi-point measurement on the thickness of the coiled material to evaluate whether the coiled material is qualified. When the existing laser thickness gauge measures the coiled material, although it can perform multi-point detection on the coiled material, during the measurement process, the coiled material warps due to its own stress and other problems and generates a gap with the placement table, resulting in inaccurate measurement parameters and affecting the evaluation of the coiled material in the later stage.

DETAILED DESCRIPTION

[0038] The following description is merely a preferred embodiment of the present invention and does not limit the scope of protection of the present invention.

[0039] Example 1: A thickness detection device for waterproofing membrane manufacturing, such as Figure 1-Figure 3As shown in the figure, it includes: a housing 1, which is set in a U-shape; a control panel 2, installed on the upper side of the housing 1. The housing 1 is fixedly connected with a detection table 3, and the detection table 3 is used to support the waterproof coiled material. The detection table 3 and the base of the housing 1 cooperate to form an isosceles trapezoid, and the angles are all greater than 120°; a moving module 4, arranged on the front side of the housing 1. The moving module 4 is an existing power component, composed of multiple electric slide rails. The specific structure of the moving module 4 is not shown in the attached drawings. The moving module 4 is provided with a laser detection head 5, and the laser detection head 5 is perpendicular to the detection table 3, and is used to detect the thickness of the waterproof coiled material. The moving module 4 is used to drive the laser detection head 5 to move, so as to perform multi-point detection on the waterproof coiled material; a lifting member 6, installed on the lower side of the top of the housing 1. The lifting member 6 is fixedly connected with a connecting frame 7. The left side of the connecting frame 7 is slidably connected with a first connecting member 8. The bottom of the first connecting member 8 is fixedly connected with an extrusion strip 9. The cross-section of the extrusion strip 9 is wedge-shaped. The inclined surface of the extrusion strip 9 faces downward and is parallel to the left inclined surface of the detection table 3. When the extrusion strip 9 moves downward, the left part of the waterproof coiled material test sample is extruded onto the left inclined surface of the detection table 3. A fixing plate is installed in the middle of the first connecting member 8. A first elastic member 10 is fixedly connected between the fixing plate of the first connecting member 8 and the connecting frame 7. The first elastic member 10 is set as a spring and is used to drive the first connecting member 8 to reset. The first elastic member 10 is sleeved on the outside of the first connecting member 8; a side pulling component, arranged on the right side of the connecting frame 7, and the side pulling component is used to perform unidirectional traction and fixation on the waterproof coiled material on the detection table 3.

[0040] As Figure 4 shown, the side pulling component includes: a slider 11. A through groove is provided on the right side of the connecting frame 7, and the slider 11 is slidably connected in the through groove of the connecting frame 7. The slider 11 can only slide horizontally along the through groove of the connecting frame 7. The lower side of the slider 11 is fixedly connected with a second connecting member 12; a roller 13, rotatably connected to the second connecting member 12. A torsion spring is fixedly connected between the roller 13 and the second connecting member 12. The torsion spring is not shown in the attached drawings and can be replaced according to the specific parameters of the waterproof coiled material, and is used to store rotational energy for the roller 13. The torsional force of the torsion spring between the roller 13 and the second connecting member 12 is greater than the frictional force between the roller 13 and the waterproof coiled material. Anti-slip rubbers are installed on both the lower inclined surface of the extrusion strip 9 and the outer ring of the roller 13, and are used to increase the frictional force between the extrusion strip 9 and the roller 13 and the waterproof coiled material. First, the roller 13 pulls the waterproof coiled material to the right through frictional force, and then the roller 13 rotates along the waterproof coiled material; a fixing rod 14, fixedly connected to the right side of the slider 11. The fixing rod 14 horizontally penetrates the through groove of the connecting frame 7, and the fixing rod 14 is slidably connected with the connecting frame 7. A second elastic member 15 is fixedly connected between the fixing rod 14 and the connecting frame 7. The second elastic member 15 is set as a tension spring and is sleeved on the outside of the fixing rod 14.

[0041] In the above scheme, the main purpose is to improve the accuracy of thickness measurement of waterproof membrane. In order to increase the structural strength of the shell 1, the shell 1 is set to be a metal material, and the front side of the upper part of the shell 1 is set to an inclined surface. The control panel 2 is installed on the inclined surface of the shell 1 to facilitate the operation of the inspector. The detection table 3 is made of metal and will not be deformed when squeezed. In order to align the waterproof membrane, a centering mechanism can be installed on the detection table 3 to correct the position of the waterproof membrane sample. The moving module 4 and the laser detection head 5 are existing structures. The structural features of the moving module 4, the laser detection head 5 and the lifting member 6 are not shown in too much detail in the attached drawings. The moving module 4 is used to drive the laser detection head 5 to achieve precise displacement. The lifting member 6 is composed of two electric push rods, and the connecting frame 7 is fixed to the telescopic ends of the two electric push rods. The control panel 2 controls the operation of the lifting member 6 to achieve the purpose of adjusting the height of the connecting frame 7. The extrusion strip 9 is made of a hard material to prevent the extrusion strip 9 from deforming when squeezing the waterproof membrane, resulting in failure to fix the waterproof membrane. The side pulling component squeezes the waterproof membrane in an inclined direction, and uses the inclined extrusion method to level the waterproof membrane to avoid detection failure caused by warping of the waterproof membrane. The height of the roller 13 is higher than the height of the extrusion strip 9. The slider 11 can only slide horizontally along the through groove on the right part of the connecting frame 7, thereby completing the fixation and tensioning of the waterproof membrane, so that the middle part of the waterproof membrane is in contact with the upper plane of the testing platform 3.

[0042] Workflow: The inspector cuts off a long strip of waterproof membrane sample and places it on the upper side of the inspection table 3 (such as Figure 1), and straighten the waterproof membrane, then press the start button of the control panel 2, the control panel 2 starts the lifting member 6, the driving end of the lifting member 6 moves downward, and the driving end of the lifting member 6 drives the connecting frame 7 and the parts thereon to move downward synchronously, as the connecting frame 7 continues to move downward, the extrusion bar 9 first squeezes the left part of the waterproof membrane, the waterproof membrane bends and fits the inclined surface of the left part of the testing platform 3, as the connecting frame 7 continues to move downward, the connecting frame 7 and the first connecting member 8 slide relative to each other, the connecting frame 7 squeezes the first elastic member 10, the first elastic member 10 is deformed, and the roller 13 is then squeezed to the right part of the waterproof membrane, and the right part of the waterproof membrane is immediately fitted on the inclined surface of the right part of the testing platform 3, as the connecting frame 7 moves downward, under the extrusion action of the inclined surface of the testing platform 3, the roller 13 moves downward along the inclined surface of the right part of the testing platform 3, and the slider 11 moves along the through groove of the connecting frame 7 to The second elastic member 15 is tightened and the fixing rod 14 slides to the right. At the beginning, the friction between the roller 13 and the waterproof membrane is used to pull the waterproof membrane in the direction of the right inclined surface of the testing platform 3. The left part of the waterproof membrane is fixed. When the right part of the waterproof membrane is tightened, the waterproof membrane is tightened and adheres to the upper side of the testing platform 3. As the connecting frame 7 continues to move downward, the roller 13 begins to rotate along the second connecting member 12. The torsion spring between the second connecting member 12 and the roller 13 begins to store force until the connecting frame 7 stops moving downward. The control panel 2 closes the lifting member 6 and starts the moving module 4. The torsion spring between the second connecting member 12 and the roller 13 stores force to ensure that the right part of the waterproof membrane is always subjected to tension along the inclined surface of the testing platform 3 during the thickness detection of the waterproof membrane, thereby preventing the waterproof membrane from warping again due to its own stress, resulting in inaccurate test values.

[0043] When testing the waterproof coiled material, the mobile module 4 drives the laser detection head 5 to move and detect multiple positions of the waterproof coiled material (the waterproof coiled material on the horizontal surface of the detection platform 3). The laser detection head 5 detects the thickness of the waterproof coiled material and feeds back the detection value to the control panel 2. After the detection of the waterproof coiled material is completed, the control panel 2 controls the mobile module 4 to reset. Then the control panel 2 turns off the mobile module 4 and starts the lifting member 6 again to move the connecting frame 7 and the parts thereon upward and reset. First, the roller 13 rotates in the opposite direction, and the torsion spring between the second connecting member 12 and the roller 13 is reset. At the same time, Under the pulling force of the elastic member 15, the slider 11 drives the roller 13 to move to the left and reset through the second connecting member 12. At the same time, the first elastic member 10 is gradually reset (the extrusion strip 9 and the waterproof membrane are still in an extruded state). After the roller 13 is separated from the waterproof membrane, the fixation on the right part of the waterproof membrane is released. As the connecting frame 7 continues to move upward, the first elastic member 10 is reset, and then the connecting frame 7 drives the extrusion strip 9 to move upward through the first connecting member 8 until the connecting frame 7 and the parts thereon are completely reset. The control panel 2 closes the lifting member 6, and the inspector removes the inspected waterproof membrane from the inspection table 3.

[0044] Example 2: Based on Example 1, Figure 2 、 Figure 3 and Figure 5 As shown, the upper side of the testing platform 3 is provided with grooves distributed at intervals, and the grooves are in the shape of long strips. The bottom of the testing platform 3 is fixedly connected to a shell, and the grooves of the testing platform 3 are connected to the bottom shell. A support net 16 is fixedly connected to the groove of the testing platform 3, and the support net 16 is flush with the plane of the testing platform 3. The support net 16 will not be deformed after being squeezed. A fan is provided in the outer shell 1, and the air inlet of the outer shell 1 is connected to the bottom shell of the testing platform 3 through an air duct.

[0045] like Figure 2 、 Figure 6 and Figure 7 As shown, a cleaning mechanism is also included. The cleaning mechanism is arranged on one side of the first connecting member 8. The cleaning mechanism is used to process the attachments on the waterproof membrane. The cleaning mechanism includes: a jet shell 17, which is fixed to the first connecting member 8. The air outlet of the jet shell 17 faces right. The jet shell 17 is equipped with a metal air inlet nozzle. The base of the outer shell 1 is fixed with a piston rod 18. The piston rod 18 is an existing structure, and its internal structure is not shown in the accompanying drawings. The piston rod 18 is provided with a one-way air inlet and an air outlet nozzle. When the telescopic end of the piston rod 18 moves downward, the air outlet nozzle of the piston rod 18 discharges gas. When the telescopic end of the piston rod 18 moves upward, the one-way air inlet of the piston rod 18 inhales air. The air inlet nozzle of the jet shell 17 and the air outlet nozzle of the piston rod 18 are connected. Air duct, the jet port of the jet shell 17 is tilted downward to form an angle with the test bench 3, which is used to process the attachments of the waterproof membrane in an inclined direction; the sleeve 19 is slidably connected to the telescopic rod of the piston rod 18, and a third elastic member 20 is fixed between the sleeve 19 and the telescopic rod of the piston rod 18. The third elastic member 20 is set as a spring. The third elastic member 20 is located in the sleeve 19, and the sleeve 19 is fixed to the connecting frame 7; the air valve 21 is installed at the air inlet nozzle of the jet shell 17, and a gear is fixed to the adjusting shaft of the air valve 21. The air valve 21 is an existing structure, and the connecting frame 7 is fixed with a toothed plate 22. The gear on the adjusting shaft of the air valve 21 is matched with the toothed plate 22 for transmission. Initially, the toothed plate 22 is not engaged with the gear on the adjusting shaft of the air valve 21.

[0046] In the above scheme, the main purpose is to improve the adhesion effect between the waterproof membrane and the upper side of the test platform 3, to avoid inaccurate test values due to edge warping of the waterproof membrane test sample, the support net 16 is made of non-deformable metal material, to provide support for the waterproof membrane, to avoid deformation of the waterproof membrane and cause errors in thickness measurement, the air inlet nozzle of the jet shell 17 is set to be made of metal material, for providing support for the air valve 21, the air outlet of the jet shell 17 is set to be flat, for forming a wind curtain to blow away impurities attached to the waterproof membrane, the sleeve 19 is set to be hollow, and the central axis of the sleeve 19 coincides with the central axis of the piston rod 18.

[0047] Working process: After the control panel 2 starts the lifting member 6, the lifting member 6 drives the connecting frame 7 to move downward, and the connecting frame 7 drives the sleeve 19 and the tooth plate 22 to move downward synchronously. Initially, the air valve 21 is in a closed state. During the downward movement of the sleeve 19, the telescopic end of the piston rod 18 remains stationary and slides relative to the sleeve 19. The third elastic member 20 is compressed. At this time, the air pressure in the piston rod 18 increases, and the tooth plate 22 gradually approaches downward. When the tooth plate 22 engages with the gear on the adjusting shaft of the air valve 21, the modulation shaft of the air valve 21 rotates, and the air valve 21 opens. Under the elastic force of the third elastic member 20, the telescopic end of the piston rod 18 moves downward, and the air in the piston rod 18 flows along the air guide pipe and is ejected from the jet shell 17. The ejected air cleans the impurities on the upper side of the waterproof membrane, thereby improving the detection accuracy of the waterproof membrane.

[0048] When the gas in the piston rod 18 is exhausted, the control panel 2 then starts the fan in the outer shell 1, and the air flows through the groove of the test platform 3 to the shell below it, and then forms multiple streams of air from the upper side of the test platform 3 (according to Bernoulli's principle: the pressure is small where the air flow speed is large). At this time, under the action of pressure, the edge of the waterproof membrane is attached to the side of the test platform 3 to avoid the increase of the test thickness value due to the warping of the edge of the waterproof membrane. After the test is completed, the control panel 2 turns off the fan in the outer shell 1, and then controls the lifting member 6 to move upward, so that the connecting frame 7 drives the sleeve 19 and the tooth plate 22 to move upward and reset. The tooth plate 22 moves upward to close the air valve 21. At the same time, when the piston rod 18 moves upward, air enters the piston rod 18 from the air inlet nozzle until the sleeve 19 is reset.

[0049] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or substitute equivalents for some of the technical features.
