[0020] The following is combined with Figure 1 -Attached Figure 8 This application is described in further detail.

[0021] The present application embodiment discloses a scanning detection device based on high-speed flat material. Figure 1 The scanning detection device based on high-speed flat material includes a beam 1 and a column 2. The beam 1 and the column 2 are both provided with two beams. The two columns 2 are vertically arranged. The two beams 1 are parallel to each other and are located between the two columns 2. The beam 1 and the column 2 are both made of I-beams. The column 2 is provided with a plug-in hole 3 for the beam 1 to be plugged in and installed. The beam 1 is welded to the column 2 through the plug-in hole 3. The beam 1 and the column 2 are both made of I-beams. The I-beams have the advantages of high strength and high bending resistance, which reduces the possibility that the bending of the column 2 and the beam 1 affects the distance between the detection devices 4 on both sides, thereby improving the detection accuracy. At the same time, the beam 1 is plugged into the column 2, and a tensile force is applied to the beam 1 toward both sides, and then the beam 1 is welded to the column 2. Under the action of the prestressed tensile force, the bending resistance of the beam 1 is further enhanced. At the same time, the beam 1 and the column 2 are fixedly connected through the installation port, which reduces the possibility that the distance between the beams 1 on both sides changes due to the bending of the column 2 under load.

[0022] Reference Figure 1 and Figure 2In the embodiment of the present application, detection devices 4 are slidably arranged on both beams 1, and the web material to be detected is clamped between the two detection devices 4 for parameter detection. The detection device 4 is slidably arranged on the beam 1, and a servo motor 5 and a drive shaft 6 are arranged on the column 2. The drive shaft 6 is parallel to the length direction of the column 2. The servo motor 5 is used to drive the drive shaft 6 to rotate. Two transmission belts 7 are sleeved on the drive shaft 6. The two transmission belts 7 correspond to the two beams 1 one by one. The transmission belt 7 is sleeved on the beam 1, and the detection device 4 is fixedly arranged on the transmission belt 7; when the web material is detected, the servo motor 5 is started, and the servo motor 5 drives the drive shaft 6 to rotate. The rotation of the drive shaft 6 drives the transmission belt 7 to run, and the operation of the transmission belt 7 drives the detection device 4 to run, and a folded path is formed on the web material, and the parameters of the web material are detected.

[0023] Reference Figure 3 , and also includes a support member for supporting the lower cross beam 1 and a prestressing device 8 for applying prestress to the upper cross beam 1, both of which are used to reduce the bending deformation of the cross beam 1. Under the action of the support member, the cross beam 1 located below is supported, thereby reducing the possibility of bending of the lower cross beam 1; under the action of the prestressing device 8, a vertical and upward pulling force is applied to the cross beam 1, thereby reducing the possibility of bending deformation of the upper cross beam 1.

[0024] In the embodiment of the present application, the support member includes a plurality of support rods fixedly set on the ground, and the lower base plate of the lower beam 1 is fixedly set at the end of the support rods to support the beam 1, which is simple and convenient to operate.

[0025] Reference Figure 3 In the embodiment of the present application, the prestressed device 8 includes a prestressed plate 81 arranged on the upper cross beam 1. The initial state of the prestressed plate 81 is a straight plate. After the prestressed plate 81 is bent, it is fixedly arranged on the cross beam 1 and close to the column 2. The prestressed device 8 also includes a steel wire rope 82. A plurality of steel wire ropes 82 are provided and are all arranged between the prestressed plate 81 and the cross beam 1. The steel wire rope 82 is in a tensile state and applies prestress to the cross beam 1 to resist deformation of the cross beam 1. After the cross beam 1 and the column 2 are installed, a prestressed plate 81 with a length greater than the distance between the two columns 2 is selected, and the prestressed plate 81 is bent and clamped between the two columns 2, and then the prestressed plate 81 is fixed on the cross beam 1, and then the steel wire rope 82 is installed. The prestressed plate 81 has a tendency to recover the deformation, and a tensile force is applied to the steel wire rope 82. The tensile force applies a vertical and upward pulling force to the cross beam 1, thereby reducing the possibility of the cross beam 1 bending downward.

[0026] Reference Figure 3 and Figure 4Furthermore, when the steel wire rope 82 is used for a long time, the steel wire rope 82 has a tendency to stretch, which makes it difficult to apply prestress to the cross beam 1. Therefore, in the embodiment of the present application, one end of the steel wire rope 82 close to the prestressed plate 81 passes through the prestressed plate 81 and is slidably arranged on the prestressed plate 81. A tightening member is arranged on the prestressed plate 81.

The tightening member includes a rotatable member arranged on the prestressed plate 81. The steel wire rope 82 is wound on the mounting shaft 83. Furthermore, a ratchet 84 is coaxially arranged on the mounting shaft 83. A pawl 85 meshing with the ratchet 84 is rotatably arranged on the prestressed plate 81. When the steel wire rope 82 is stretched, the mounting shaft 83 is rotated, and the mounting shaft 83 is rotated to reel in the steel wire rope 82 to tighten the steel wire rope 82. Subsequently, the pawl 85 meshes in the ratchet teeth of the ratchet 84, and the mounting shaft 83 is fixed, so that the steel wire rope 82 returns to the stretched state. The operation is simple and convenient.

[0027] Reference Figure 5 , Figure 6 and Figure 7 Due to the spacing between the steel wire ropes 82, when the detection device 4 runs between the adjacent steel wire ropes 82, the gravity of the detection device 4 acts on the beam 1, which easily causes the corresponding part of the beam 1 to be deformed. Therefore, in the embodiment of the present application, the detection device 4 includes a mounting seat 41, a detection platform 42 and a connecting plate 43. The mounting seat 41 is slidably connected to the beam 1, the detection platform 42 is fixedly arranged on the mounting seat 41 and is used to install the detection component, and the connecting plate 43 is fixedly arranged on the detection platform 42 and is used to be fixedly connected to the transmission belt 7.

[0028] Reference Figure 5 , Figure 6 and Figure 7In the embodiment of the present application, the movable stress member 86 includes a sliding seat 861 arranged on the prestressed plate 81, and the sliding seat 861 slides along the curvature direction of the prestressed plate 81.

A T-shaped block 862 is provided on the cross beam 1 and is located in the T-shaped slot 11 and slides. The T-shaped block 862 slides along the length direction of the T-shaped slot 11. The movable stress member 86 also includes a stress motor 863 arranged on the sliding seat 861 and a coiled stress motor 863 on the output shaft. Suspension rope 864, further, the upper bottom plate of the beam 1 is provided with a long strip notch 12 for the suspension rope 864 to pass through, the suspension rope 864 is fixedly set on the T-shaped block 862, and the connecting plate 43 is fixedly provided with a side plate 865, the side plate 865 is perpendicular to the middle plate of the beam 1, and the side plate 865 is provided with a through hole 13 for the suspension rope 864 to pass through, the stress motor 863 reels the suspension rope 864 and applies tension to the beam 1, the connecting plate 43 moves to drive the suspension rope 864 to translate along the beam 1 and drives the sliding seat 861 to slide along the prestressed plate 81.

[0029] When the width material is detected, the stress motor 863 is started, the stress motor 863 reels the suspension rope 864, the suspension rope 864 applies an upward pulling force to the T-block 862, and the T-block 862 applies an upward pulling force to the beam 1, thereby reducing the possibility of bending of the beam 1; and, under the action of the connecting plate 43 and the side plate 865, when the detection device 4 is in operation, it drives the suspension rope 864 to translate, and the translation of the suspension rope 864 drives the T-block and the sliding seat 861 to translate, so that the suspension rope 864 applies a pulling force to the beam 1 in real time, thereby reducing the possibility of bending of the beam 1.

[0030] Reference Figure 7 and Figure 8In the embodiment of the present application, the stress motor 863 includes a first motor 8631, an inner rotor 8632 and an outer rotor 8633. The outer rotor 8633 is arranged on the output shaft of the first motor 8631 and is cylindrical. The inner rotor 8632 is rotatably arranged on the sliding seat 861 and is sleeved in the outer rotor 8633. The outer wall of the inner rotor 8632 and the inner wall of the outer rotor 8633 are in a separated state. A winding shaft is coaxially arranged on the inner rotor 8632. The inner rotor 863 Multiple permanent magnets 8634 are arranged on the outer wall and the inner wall of the outer rotor 8633. The permanent magnets 8634 located on the outer wall of the inner rotor 8632 are evenly arranged along the axis of the inner rotor 8632, and the permanent magnets 8634 located in the outer rotor 8633 are evenly arranged along the axis of the outer rotor 8633. The permanent magnets 8634 on the outer rotor 8633 attract the permanent magnets 8634 on the inner rotor 8632, thereby driving the inner rotor 8632 to rotate and driving the reel shaft to reel the suspension rope 864. When the sliding seat 861 follows the inspection device to run, the first motor 8631 is started, and the first motor 8631 drives the outer rotor 8633 to rotate, and the outer rotor 8633 rotates to drive the inner rotor 8632 to rotate, and the inner rotor 8632 rotates to reel the suspension rope 864; when the detection device 4 is running, the length of the suspension rope 864 gradually increases and then decreases. When the length of the suspension rope 864 increases, the inner rotor 8632 is driven to passively reverse and release the suspension rope 864. At this time, the outer rotor 8633 applies a positive rotation driving force to the inner rotor 8632. Under the action of the driving force, the suspension rope 864 is in a taut state. When the detection device 4 passes the highest point of the prestressed plate 81, the inner rotor 8632 rotates forward to reel the suspension rope 864, and applies tension to the crossbeam 1. The operation is simple and convenient. At the same time, under the action of the inner rotor 8632, the outer rotor 8633 and the permanent magnet 8634, it is convenient to tighten the suspension rope 864 in real time.

[0031] Reference Figure 5 , Figure 6 and Figure 7 In order to facilitate the synchronous operation of the sliding seat 861 and the detection device 4, a multi-stage telescopic tube 14 is arranged between the sliding seat 861 and the T-shaped block 862, and the two ends of the telescopic tube 14 are respectively fixed on the sliding seat 861 and the T-shaped block 862, and the suspension rope 864 is located in the telescopic tube 14, and the telescopic tube 14 is fixed on the side plate 865 through the through hole 13; under the action of the multi-stage telescopic tube 14, it is convenient for the side plate 865 to drive the telescopic tube 14, the sliding seat 861 and the T-shaped block 862 to operate synchronously.

[0032] Reference Figure 6 and Figure 7In the embodiment of the present application, an arc groove 15 is provided on the side wall of the prestressed plate 81, and the curvature of the arc groove 15 is consistent with the curvature of the prestressed plate 81. A disc 16 is rotatably provided on the sliding seat 861, and the disc 16 is slidably engaged in the arc groove 15; under the action of the arc groove 15, the sliding seat 861 is easy to slide along the prestressed plate 81.

[0033] Reference Figure 5 , Figure 6 and Figure 7 When the detection device 4 moves back and forth on the beam 1, the friction between the mounting seat 41 and the beam 1 causes the temperature of the beam 1 to rise. When the temperature of the beam 1 rises, it is easy to cause the beam 1 to bend and deform. Therefore, in the implementation of this application, a first electromagnet 17 is provided at the bottom of the slide rail 9, and a second electromagnet 18 is provided at the lower part of the mounting seat 41 that slides and is engaged in the slide groove 10. The connecting plate 43 is located between the transmission belt 7 and the detection platform 42 and is a telescopic structure. After the first electromagnet 17 and the second electromagnet 18 are energized, the mounting seat 41 is in a suspended state and the mounting seat 41 is in a separated state from the beam 1 and the slide rail 9; under the action of the first electromagnet 17 and the second electromagnet 18, the mounting seat 41 is suspended and separated from the beam 1. When the detection device 4 is running, the mounting seat 41 is non-contact with the beam 1, which reduces the possibility of the temperature of the beam 1 rising, thereby keeping the beam 1 at room temperature and reducing the possibility of the beam 1 bending.

[0034] Reference Figure 5 , Figure 6 and Figure 7 In order to reduce the possibility of the mounting seat 41 shaking in the slide groove 10, a guide wheel 19 is rotatably arranged on the mounting seat 41, and the rotation axis of the guide wheel 19 is perpendicular to the middle plate of the beam 1. The guide wheel 19 is used for the mounting seat 41 to be suspended, and the peripheral wall of the guide wheel 19 abuts against the lower bottom plate of the beam 1; after the mounting seat 41 is suspended, the guide wheel 19 rises and abuts against the lower bottom plate of the beam 1, thereby positioning the mounting seat 41. Furthermore, the guide wheel 19 is hollow and has a coolant inside; under the action of the coolant, the possibility of the temperature of the beam 1 rising due to the friction between the guide wheel 19 and the beam 1 is reduced.

[0035] The implementation principle of a scanning detection device based on high-speed flat material in the embodiment of the present application is as follows: When the web material is detected, the servo motor 5 is started, the servo motor 5 drives the driving shaft 6 to rotate, the driving shaft 6 rotates to drive the transmission belt 7 to run, the transmission belt 7 runs to drive the detection device 4 to run, and a folded path is formed on the web material, and the parameters of the web material are detected; When the detection device 4 is running, the first motor 8631 is started, and the first motor 8631 drives the outer rotor 8633 to rotate. The rotation of the outer rotor 8633 drives the inner rotor 8632 to rotate, and the rotation of the inner rotor 8632 reels the suspension rope 864. When the detection device 4 is running, the length of the suspension rope 864 gradually increases and then decreases. When the length of the suspension rope 864 increases, the inner rotor 8632 is driven to passively reverse and release the suspension rope 864. At this time, the outer rotor 8633 applies a positive rotation driving force to the inner rotor 8632. Under the action of the driving force, the suspension rope 864 is in a taut state. When the detection device 4 passes over the highest point of the prestressed plate 81, the inner rotor 8632 rotates forward to reel in the suspension rope 864, and applies tension to the beam 1, thereby reducing the possibility of bending of the beam 1.

[0036] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
