The horizontal traversing mechanism 2 is a main structure of the measuring device, as shown in fig. 2 and 4, and is used for realizing horizontal movement of the non-contact displacement signal acquisition mechanism 3 in the width direction (i.e. the transverse direction) of the steel coil and measuring height fluctuation of the surface of the steel coil in the transverse direction; can be installed on the device shell 1 by means of screw connection, welding and the like; the profile quality defects of the steel coil, such as bulges, bulges and the like, can be reflected by analyzing the height-displacement curve. In the present embodiment, the guide rail 12 spans the width direction of the whole steel coil to ensure that the moving stroke of the sliding block 13 on the guide rail 12 completely covers the width range of the steel coil; the non-contact displacement signal acquisition mechanism 3 is mounted on the slide block 13. The motor 11 is used as a driving device, and the steel coil profile data in the whole steel coil width direction can be obtained in one measurement process. An alternative transmission configuration is as follows: an output shaft of the motor 11 is in belt transmission to the guide rail 12 through a conveying belt, a sliding block 13 is arranged on the belt, and the sliding block 13 can horizontally move back and forth on the guide rail 12 under the driving of the motor 11; during the horizontal traverse of the slider 13, the data of the lateral displacement of the slider 13 is output by an encoder in the motor 11.

Optionally, the input voltage of the power supply mechanism 4 is 220V, the output voltage is 24V, and the output current is 5A. On the premise of meeting the power supply indexes, the power supply mechanism 4 should select a power supply module with the smallest size, light weight and large capacity.
It is worth mentioning that, before the solution of the present embodiment, the applicant has used another measuring device, which includes a running mechanism including a roller and a cantilever, which performs a plurality of movements (such as a hand-pushing type) on the surface of the steel coil; then a rotary encoder controlled by a spring and contacted with the surface of the steel coil is adopted to acquire transverse displacement signals, and a contact type displacement sensor controlled by the spring and contacted with the surface of the strip steel is adopted to acquire height signals. During measurement, a sliding mechanism drives a rotary encoder and a contact type displacement sensor which are connected with a spring to walk on the surface of the steel coil so as to obtain a displacement signal and a height signal, and the spring is used for ensuring that the rotary encoder and the displacement sensor are always in contact with the surface of the steel coil; after a measuring area is completed, the walking mechanism moves to another detection position to repeat the process.
However, when using the above-described device, it was found that there were several problems: firstly, the measuring device needs to be moved for many times when the width direction of the whole steel coil is completely measured, the measuring process is inconvenient, certain position deviation is inevitably generated, and the precision of the measuring result is influenced; secondly, the moving measuring device is realized through a cantilever-roller structure of the traveling mechanism in the measuring process, and the actual measurement data of the contact type displacement sensor can be directly influenced due to the different heights possibly existing at different positions on the surface of the steel coil; for example, the height of the roller at the position 1 is Δ h1, the height at the position 2 is Δ h2, and the actual data of the bulge at a certain position of the steel coil is Δ h3, different positions of the roller will have different influences on the actual measurement data of the contact type displacement sensor, that is, the actual measurement data of the sensor are respectively Δ h3- Δ h1 and Δ h3- Δ h2, so the change of the relative height of the roller will cause the accuracy of the actual measurement data to be obviously reduced, and the actual situation of the profile of the steel coil cannot be accurately reflected; thirdly, the height of the contact type rotary encoder and the displacement sensor is inconvenient to adjust at the initial measuring point of the edge of the steel coil, if the position is adjusted to be low, the sensor and the encoder are blocked by the edge of the strip steel, and if the position is adjusted to be high, the data cannot be measured; on the other hand, in the sliding process, the rotary encoder and the displacement sensor are always in contact with the surface of the strip steel, so that scratches are easily generated on the surface of the steel coil, and particularly for high surface quality level requirements, such as O5 level steel coils, new defects are introduced to cause unnecessary coil cutting.
Based on this, the measuring device in this embodiment is improved, so that the horizontal traversing mechanism 2 which spans the whole steel coil width and comprises the motor 11, the guide rail 12 and the sliding block 13 is adopted, and the horizontal traversing stroke of the sliding block 13 on the guide rail 12 is required to be larger than the actual width of the steel coil, so as to ensure that the measuring device can conveniently obtain the height fluctuation of the whole steel coil width through one-time measurement, eliminate the measurement error of the displacement signal acquisition mechanism caused by moving the measuring device for many times, and improve the accuracy of the steel coil profile measurement; the non-contact displacement signal acquisition mechanism 3 is limited to be used, so that on one hand, the height position of the displacement signal acquisition mechanism can be conveniently and quickly set, the convenience of measuring the outline of the steel coil is improved, and the problem that the sensor collides with the edge of the steel coil due to improper position setting is avoided; on the other hand, the displacement signal acquisition mechanism is prevented from contacting the surface of the strip steel, and the hidden trouble of introducing additional surface damage is eliminated.
The following description will be made by referring to the specific implementation data, the measuring device in this embodiment is applied to a cold rolling galvanizing production line in a certain steel mill in China, measuring the outline of the galvanized steel coil after the coil is off-line, wherein the outline measuring result curve is shown in figure 7, wherein the abscissa is the width data of the steel coil determined by the horizontal traverse coordinate of the sliding block, the ordinate is the relative height data (taking the initial measurement point at one end of the steel coil as a point 0) of the surface of the steel coil acquired by the non-contact laser displacement sensor, the profile measurement curve actually represents the height fluctuation of the surface of the steel coil, can better reflect the actual contour quality of the steel coil, and determine the quantitative height difference and the local defect characteristics of the steel coil at each position in the width direction by analyzing the curve, so as to see that, in fig. 7, there are defects of "bulge" at A, B, and the defect at A, B may have quality problems such as wave shape in the subsequent uncoiling use.
This embodiment provides a measuring device of coil of strip profile, drive non-contact displacement signal acquisition mechanism horizontal sideslip on the width direction of coil of strip through the motor drive slider in the horizontal sideslip mechanism, height data and the lateral displacement data of accurate, efficient collection sign coil of strip surface profile to according to height data and displacement data ration evaluate coil of strip profile quality, in order to avoid the profile quality to be improper, if there is the swell, the coil of strip entering low reaches user of uplift defect, cause unnecessary economic loss. Meanwhile, the conversion relation between the outline defect and the uncoiled wave-shaped defect can be analyzed according to the quantitative evaluation result, and technical guidance is provided for subsequent process optimization.

the operation parameters of the motor 11 and the displacement coordinates of the slider 13 are set through the touch display 52, and the motor 11 controls the slider 13 to horizontally move according to the operation parameters and the displacement coordinates. That is, the entire function of the electric mechanism 5 can be realized by the man-machine interaction of the touch display 52.
