Description

Technical Field

[0001] This invention relates to the field of color steel plate testing technology, specifically to a color steel plate testing device and its testing method. Background Technology

[0002] Color-coated steel sheet refers to pre-painted steel sheet, which is a type of steel sheet with an organic coating. It mainly consists of a steel sheet body, a coating layer, and a paint layer. Color-coated steel sheets can be made into composite panels and floor decking, and are widely used for walls and roofs of large public buildings, public factories, prefabricated houses, and prefabricated housing. The coating layer and paint layer improve the durability of the color-coated steel sheet, and the thickness of the sheet also affects its performance to some extent. Therefore, during the production of color-coated steel sheets, it is necessary not only to measure the coil length but also to inspect the thickness of the coating layer and paint layer.

[0003] In existing technologies, the thickness of the coating and plating of color steel sheets is often measured manually using a handheld non-magnetic thickness gauge for surface contact testing. However, this testing method involves sampling at various locations on the color steel sheet, which is relatively cumbersome. Furthermore, in mass production of color steel sheets, sampling can easily result in some products failing to meet standards, thereby affecting the company's reputation and customer loyalty, causing unnecessary trouble and financial losses.

The support shaft of the lightweight support roller is horizontally inserted into the second transmission groove and fitted with a second transmission wheel. A transmission belt is connected between the first transmission wheel and the second transmission wheel. The clamping friction between the color steel plate and the lightweight support roller and the extrusion roller is greater than the sliding friction of the sliding block driven by the traveling belt in the traveling groove.

[0019] A method for inspecting color-coated steel sheets, wherein the method is applied to the aforementioned color-coated steel sheet inspection device, includes the following steps:

[0020] Step 1: Adjust the position of the side baffle according to the width of the color steel plate so that the color steel plate is laid stably above the lifting roller frame, and connect one side to the winding machine for winding. The winding machine pulls and drags the color steel plate.

[0021] Step 2: When the color steel plate moves normally on the surface of the lifting roller frame, under the high-intensity downward pressure of several first and second downward springs, in conjunction with the anti-slip textured rubber layer on the surface of the extrusion roller and the lightweight support roller, the lightweight support roller and the extrusion roller rotate.

[0022] Step 3: When the lightweight support roller rotates, the rotation count recognition module automatically identifies and senses several sensing modules that the lightweight support roller passes through, and records the winding length of the color steel plate in real time. When the winding length of the color steel plate meets the standard, the worm gear is driven to control the installation platform to rotate. At this time, the second actuating gear of the installation platform disengages from the first actuating gear below it, and the slitting blade of the installation platform points vertically to the strip groove of the detection platform. The lifting cylinder pulls the lifting platform and the lightweight support roller to descend synchronously, and the slitting blade cuts the color steel plate that meets the length.

[0023] Step 4: During the forward winding of the color steel plate, as the lightweight support roller rotates, the second and first transmission wheels continue to rotate. At this time, the first transmission wheel drives the first actuating gear to control the rotation of the second actuating gear. Then, the second actuating gear controls the rotation of the traction wheel through the second bevel gear and the first bevel gear. As a result, the traveling belt pulls the pulling drum and the mounting slider connected to the traction rod to slide horizontally in the traveling groove. During this period, as the pulling drum and the rotating sleeve rotate, the mounting slider moves back and forth in the traveling groove when the traveling belt rotates in a cycle. The coating detection head maintains a vertical posture and does not over-wrap the connected wires. At the same time, the sliding is smooth and reliable under the action of the sliding balls.

[0024] Step 5: When it is necessary to inspect the coating and thickness of the color steel plate, keep the coating inspection head vertically pointing at the color steel plate, control the lifting cylinder to lower the lifting platform, and push the pressing bracket along the first anti-detachment rod and the second anti-detachment rod to press the first pressing spring and the second pressing spring. The lower end of the coating inspection head contacts the color steel plate and performs random left and right position inspections on the surface of the color steel plate to improve the production inspection quality of the color steel plate.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] The length measuring device and coating inspection head are integrated into a single unit by using a testing workbench, lifting platform, and mounting platform. During normal coiling operations in the production of color steel sheets, the device moves in conjunction with the movement of the sheet to drive the driven components for length measurement. Simultaneously, the position of the coating inspection head can be randomly adjusted. When it is necessary to measure the coating thickness on the surface of the color steel sheet, the lifting components can be used for rapid measurement, increasing the frequency of inspections, enhancing product quality control, and reducing labor costs. Furthermore, with the cooperation of the flipping components and slitting blade, the device can complete the coiling and slitting of the color steel sheet. It is a fully functional and convenient device. Attached Figure Description

[0045] Please see the appendix Figure 1-16 This application provides the following five preferred embodiments.

[0046] Example 1

The two guide columns 6 are vertically and movably inserted into the lower end of the inspection workbench 1. The lifting cylinder 7 is vertically located in the center of the lifting groove, and the upper end of the lifting cylinder 7 is connected to the lower end of the lifting platform 5. The inspection workbench 1 supports the lifting roller frame 2. The lifting platform 5 does not affect the normal movement of the color steel plate 3 during the lifting and lowering activities.

[0048] The color steel plate inspection device disclosed in Embodiment 2 of the present invention has a structure that is basically the same as that in Embodiment 1. The difference is that the coating inspection head 34 is installed by a mounting assembly that is horizontally mounted on the upper end of the lifting platform 5 via a flipping assembly. The mounting assembly includes a mounting platform 8, which is located above the lifting roller frame 2. The flipping assembly includes two drive worm gears 10. Circular grooves are symmetrically opened on both sides of the lifting platform 5. The mounting platform 8 is horizontally inserted into the center of the two circular grooves on both sides. Two flipping shafts are symmetrically arranged on both sides of the mounting platform 8. The two flipping shafts are respectively inserted into the two sides of the lifting platform 5 through bearings. A control groove is opened on one side of the flipping shaft in the lifting platform 5. A drive turbine 9 is sleeved in the control groove of each flipping shaft. A drive worm gear 10 is vertically arranged on one side of the control groove through a bearing, and one side of the drive worm gear 10 is meshed with the drive turbine 9. The coating inspection head 34 passes through the mounting scene, and the rotation of the mounting platform 8 can assist the subsequent cutting operation of the slitting blade 43.

[0049] The color steel plate testing device disclosed in Embodiment 3 of this invention has a structure that is basically the same as that in Embodiment 2. The difference is that the position of the coating detection head 34 is randomly moved to improve the uniformity and accuracy of the detection. The random detection component is movably disposed at the lower end of one side of the mounting platform 8. The random detection component includes a traveling belt 22, a mounting slider 29, and a coating detection head 34. A traction groove 20 is horizontally opened on one side of the mounting platform 8. Two traction wheels 21 are horizontally symmetrically arranged on both sides of the traction groove 20. The traveling belt 22 is horizontally movably sleeved on the two traction wheels 21. A traveling groove 27 is opened through the mounting platform 8 at the lower end of the traction groove 20. Two sliding grooves 28 are horizontally symmetrically opened on both sides of the traveling groove 27. The mounting slider 29 is horizontally movably disposed in the traveling groove 27. Two constraint sliders 30 are horizontally symmetrically arranged on both sides of the mounting slider 29. The two constraint sliders 30 are respectively movably inserted into the two sliding grooves 28. Several ball grooves are horizontally symmetrically opened on one side of the sliding grooves 28 into which the constraint sliders 30 are inserted. The sliding ball bearing 31 is movably inserted into the inner part of the sliding groove 28, and one side of the sliding ball bearing 31 passes through the ball groove and fits against one side of the inner side of the sliding groove 28. The center of the mounting slider 29 is rotatably inserted into the pull cylinder 32 via a bearing. The upper end of the pull cylinder 32 is inserted into the traction groove 20, and a disc is horizontally arranged inside. A pull rod 35 is vertically arranged on one side of the upper end of the disc. A lubrication sleeve is vertically inserted into one side of the traveling belt 22. The upper end of the pull rod 35 is movably inserted into the lubrication sleeve. The center of the pull cylinder 32 is rotatably inserted into the self-rotating part via a bearing. The upper end of the coating detection head 34 is vertically inserted into the rotating sleeve 33 by bolts. The lower end of the coating detection head 34 is vertically pointed towards the color steel plate 3. A connecting wire is provided on the side of the coating detection head 34 that protrudes from the lower end of the rotating sleeve 33. When the rotating wheel 21 is driven to rotate, the traveling belt 22 moves. However, the position of the traveling belt 22 is uncontrollable. Combined with the continuous winding of the color steel plate 3, it is not easy to manually determine the detection position during the inspection. Under high-frequency inspection, the inspection quality of the color steel plate 3 is improved.

[0050] The color steel plate testing device disclosed in Embodiment 4 of this invention has a structure that is basically the same as that in Embodiment 3, except that: the driven component for transmitting the movement of the coating detection head 34 is horizontally arranged on one side of the lifting platform 5. The driven component includes a lightweight support roller 12 and a pressing roller 38, and the pressing roller 38 and the lightweight support roller 12 are respectively in contact with the upper and lower sides of the color steel plate 3. The lifting roller frame 2 is horizontally arranged with a testing platform 11 directly below the mounting platform 8. A roller groove is opened in the testing platform 11, and a strip groove is opened through the center of the testing platform 11 at the upper end of the roller groove. The upper end of the mounting platform 8 is located at the center of the strip groove. A slitting blade 43 is horizontally positioned above the light support roller 12. The length of the strip groove is greater than the length of the slitting blade 43. The light support roller 12 is horizontally positioned within the strip groove, with its upper end penetrating the groove and fitting snugly against the lower end of the color steel plate 3. A lifting platform 5 is horizontally positioned on both sides of the light support roller 12, each equipped with a sensor mounting seat 13. Two support shafts are symmetrically positioned horizontally on both sides of the light support roller 12, and each support shaft is movably connected to one of the sensor mounting seats 13 via bearings. A rotation count recognition module 14 is horizontally positioned on the side of the sensor mounting seat 13 closest to the light support roller 12, and the side of the light support roller 12 closest to the rotation count recognition module 14 is annular. The array is equipped with several sensing modules 15. A vertically extending downward constraint groove 36 is provided on the lower end of the mounting platform 8, away from the coating detection head 34. A downward support 37, L-shaped in structure, is provided on one side of the extrusion roller 38 via a bearing. The vertical end of the downward support 37 is movably inserted into the downward constraint groove 36. Several first anti-detachment rods 39 are symmetrically arranged vertically at the upper end of the downward support 37 inserted into the downward constraint groove 36. The upper ends of the first anti-detachment rods 39 are movably inserted into the mounting platform 8. A first downward spring 40 is sleeved on one side of each first anti-detachment rod 39 located within the downward constraint groove 36. A second anti-detachment rod 41 is vertically installed on the upper ends of both sides of the extrusion roller 38. The upper ends of the two second anti-detachment rods 41 are vertically and movably inserted into the lower end of the mounting platform 8. A second pressure spring 42 is sleeved between the lower pressure bracket 37 and the mounting platform 8. The extrusion roller 38 is located directly above the lightweight support roller 12. The outer periphery of both the extrusion roller 38 and the lightweight support roller 12 is provided with an anti-slip textured adhesive layer. The two sides of the color steel plate 3 are pressed and contacted with the anti-slip textured adhesive layers of the lightweight support roller 12 and the extrusion roller 38, respectively. The movement of the color steel plate 3 drives the movement of the lightweight support roller 12 and the traveling belt 22.

[0051] The color steel plate testing device disclosed in Embodiment 5 of this invention has a structure that is basically the same as that in Embodiment 4, except that: a first transmission groove is provided on the upper end of the traction wheel 21 located on one side of the mounting platform 8. The mounting shaft of the traction wheel 21 is movably inserted into the first transmission groove and fitted with a first bevel gear 23. A gear shaft 24 is horizontally provided on one side of the mounting platform 8 through the first transmission groove via a bearing. A second bevel gear 25 and a second actuating gear 26 are respectively provided on the gear shaft 24 located inside the first transmission groove and outside the mounting platform 8. The second bevel gear 25 meshes with the first bevel gear 23. The diameter of the first bevel gear 23 is larger than the diameter of the second bevel gear 25. A second transmission groove is inclinedly provided on one side of the lifting platform 5. The upper end of the transmission groove is pierced by a bearing. A synchronous shaft is provided in the insert circular groove. The synchronous shaft is located in the second transmission groove and the circular groove respectively, and a first transmission wheel 17 and a first actuating gear 16 are respectively provided. The first actuating gear 16 and the second actuating gear 26 are meshed and connected. The support shaft of the lightweight support roller 12 is horizontally inserted into the second transmission groove and sleeved with a second transmission wheel 18. A transmission belt 19 is connected between the first transmission wheel 17 and the second transmission wheel 18. The clamping friction between the color steel plate 3 and the lightweight support roller 12 and the extrusion roller 38 is greater than the sliding friction of the sliding belt 22 driving the mounting slider 29 in the walking groove 27. When the lightweight support roller 12 rotates one revolution, the walking distance of the walking belt 22 is limited, thereby avoiding the high-speed left and right movement of the coating detection head 34 when the color steel plate 3 is quickly rolled up.

[0052] The first drive wheel 17 and the second drive wheel 18 can be sprockets, and the drive belt 19 can be a suitable lightweight chain.

[0053] A method for testing color steel sheets includes the following steps:

[0054] Step 1: Adjust the position of the side baffle 4 according to the width of the color steel plate 3 so that the color steel plate 3 is laid stably above the lifting roller frame 2, and connect one side to the winding machine for winding. The winding machine pulls and drags the color steel plate 3.

[0055] Step 2: When the color steel plate 3 moves normally on the surface of the lifting roller frame 2, under the high-intensity downward pressure of several first pressing springs 40 and second pressing springs 42, in conjunction with the anti-slip textured adhesive layer on the surface of the extrusion roller 38 and the lightweight support roller 12, the lightweight support roller 12 and the extrusion roller 38 are driven to rotate.

[0056] Step 3: When the lightweight support roller 12 rotates, the rotation number recognition module 14 automatically recognizes and senses several sensing modules 15 that the lightweight support roller 12 passes through, and records the winding length of the color steel plate 3 in real time. When the winding length of the color steel plate 3 meets the standard, the drive worm gear 10 controls the mounting platform 8 to rotate. At this time, the second actuating gear 26 of the mounting platform 8 disengages from the first actuating gear 16 from below. The slitting blade 43 of the mounting platform 8 points vertically to the strip groove of the detection platform 11. The lifting cylinder 7 pulls the lifting platform 5 and the lightweight support roller 12 to descend synchronously. The slitting blade 43 cuts the color steel plate 3 that meets the length.

[0057] Step 4: During the rewinding process of the color steel plate 3, as the lightweight support roller 12 rotates, the second transmission wheel 18 and the first transmission wheel 17 continue to rotate. At this time, the first transmission wheel 17 drives the first actuating gear 16 to control the rotation of the second actuating gear 26. Then, the second actuating gear 26 controls the rotation of the traction wheel 21 through the second bevel gear 25 and the first bevel gear 23. As a result, the walking belt 22 pulls the pulling drum 32 and the mounting slider 29 connected to the traction rod 35 to slide horizontally in the walking groove 27. During this period, as the pulling drum 32 and the rotating sleeve 33 rotate, when the walking belt 22 rotates in a cycle, the mounting slider 29 moves back and forth in the walking groove 27. The coating detection head 34 maintains a vertical posture and does not over-wrap the connected wires. At the same time, the sliding is smooth and reliable under the action of the sliding ball 31.

[0058] Step 5: When it is necessary to inspect the coating and thickness of the color steel plate 3, keep the coating inspection head 34 vertically pointing towards the color steel plate 3, the lifting cylinder 7 controls the lifting platform 5 to descend, the extrusion roller 38 pushes the lowering bracket 37 to squeeze the first lowering spring 40 and the second lowering spring 42 along the first anti-detachment rod 39 and the second anti-detachment rod 41, and the lower end of the coating inspection head 34 contacts the color steel plate 3 to perform random left and right position inspections on the surface of the color steel plate 3, thereby improving the production inspection quality of the color steel plate 3.

[0059] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

6. A method for testing color-coated steel sheets, characterized in that: The color steel plate testing method is applied to the color steel plate testing device according to claim 5, and includes the following steps: Step 1: Adjust the position of the side baffle (4) according to the width of the color steel plate (3) so that the color steel plate (3) is laid stably on the top of the lifting roller frame (2) and one side is connected to the winding machine for winding. The color steel plate (3) is pulled and dragged by the winding machine. Step 2: When the color steel plate (3) moves normally on the surface of the lifting roller frame (2), under the high-intensity downward pressure of several first pressing springs (40) and second pressing springs (42), in conjunction with the anti-slip textured adhesive layer on the surface of the extrusion roller (38) and the lightweight support roller (12), the lightweight support roller (12) and the extrusion roller (38) rotate. Step 3: When the lightweight support roller (12) rotates, the number of rotations identification module (14) automatically identifies and senses several sensing modules (15) that the lightweight support roller (12) passes through, and records the winding length of the color steel plate (3) in real time. When the winding length of the color steel plate (3) meets the standard, the drive worm gear (10) controls the installation platform (8) to rotate. At this time, the second actuating gear (26) of the installation platform (8) disengages from the first actuating gear (16) from below. The slitting blade (43) of the installation platform (8) points vertically to the strip groove of the detection platform (11). The lifting cylinder (7) pulls the lifting platform (5) and the lightweight support roller (12) to descend synchronously. The slitting blade (43) cuts the color steel plate (3) that meets the length. Step 4: During the rewinding process of the color steel plate (3), as the rotation of the lightweight support roller (12) controls the second transmission wheel (18) and the first transmission wheel (17) to rotate continuously, the first transmission wheel (17) drives the first actuating gear (16) to control the rotation of the second actuating gear (26). Then, the second actuating gear (26) controls the rotation of the traction wheel (21) through the second bevel gear (25) and the first bevel gear (23). As a result, the walking belt (22) pulls the pulling drum (32) and the mounting slider (29) connected to the traction rod (35) to slide horizontally in the walking groove (27). During this period, as the pulling drum (32) and the rotating sleeve (33) rotate, when the walking belt (22) rotates in a cycle, the mounting slider (29) moves back and forth in the walking groove (27). The coating detection head (34) maintains a vertical posture and does not over-wrap the connected wires. At the same time, the sliding is smooth and reliable under the action of the sliding ball (31). Step 5: When it is necessary to test the coating and thickness of the color steel plate (3), keep the coating test head (34) vertically pointing towards the color steel plate (3), the lifting cylinder (7) controls the lifting platform (5) to descend, the extrusion roller (38) pushes the pressure bracket (37) to press the first pressure spring (40) and the second pressure spring (42) along the first anti-detachment rod (39) and the second anti-detachment rod (41), and the lower end of the coating test head (34) contacts the color steel plate (3) to perform random left and right position tests on the surface of the color steel plate (3) to improve the production test quality of the color steel plate (3).
