Description

Technical Field

[0001] The utility model belongs to the technical field of steel tape production, and relates to a device for detecting steel strips, which is used for detecting the steel strips for producing the tape and the tape spring of the steel tape. Background Art

[0002] In the production process of steel tapes, steel strips are required for manufacturing the tape and the tape spring. In the production and processing of steel strips, the following situations exist:

[0003] First, continuous operation must be carried out during the heat treatment process, and the steel strips need to be welded together:

[0004] Second, when cutting the steel strip, there is an error in the width of the steel strip being too wide;

[0005] Third, during the handling of the steel strip, problems such as being crushed or bent are likely to occur.

[0006] However, the tape and the tape spring have strict requirements on the thickness and width of the steel strip and must be produced according to the standards. Therefore, it is necessary to accurately screen out the abnormal steel strips to prevent the abnormal steel strips from flowing into the subsequent processes. Summary of the Invention

[0007] The technical problem to be solved by the utility model is to provide a device for detecting steel strips with a simple and reasonable structure, convenient and accurate detection in view of the above technical status.

[0008] The technical solution adopted by the utility model to solve the above technical problem is as follows: A device for detecting steel strips, characterized in that: it includes a limiting block and an induction probe. The limiting block is arranged on the conveying line of the steel strip in a position-limited and movable manner. A limiting groove for the steel strip to pass through is opened in the limiting block. The width and thickness of the limiting groove are the same as those of the qualified steel strip. The steel strip of the steel strip roll to be detected passes through the limiting groove of the limiting block and is wound on the qualified steel strip roll. The induction probe is installed behind the limiting block. When the width or thickness of the steel strip exceeds the limiting groove, the steel strip cannot pass through the limiting groove. When the limiting block runs to the position of the induction probe along the conveying direction under the drive of the steel strip, the induction probe detects the limiting block and outputs an abnormal signal.

[0009] As an improvement, starting points and end points for limiting the movement of the limiting block are provided on the conveying line of the steel strip, and the induction probe is installed at the position of the end point.

[0010] Furthermore, a first guide wheel, a second guide wheel, a tensioning wheel, a third guide wheel and a fourth guide wheel are sequentially arranged on the conveying line of the steel strip. The steel strip of the steel strip roll to be detected passes upward through the first guide wheel and the second guide wheel, then passes downward through the tensioning wheel, and then passes upward through the third guide wheel and the fourth guide wheel and is wound on the qualified steel strip roll. The limiting block and the induction probe are sequentially arranged on the conveying line between the tensioning wheel and the third guide wheel.

[0011] Further, the induction probes are divided into two types, one is a proximity sensor probe and the other is a photoelectric sensor probe.

[0012] Finally, it further includes a control system. The output of the induction probe is connected to the control system, and the output of the control system is connected to the actuator and the alarm device. When the induction probe detects the limiting block, it outputs an abnormal signal to the control system. The control system immediately stops the vehicle through the actuator and issues an alarm through the alarm device for the staff to operate: cut off the abnormal steel strip and reset the limiting block to the starting point.

[0013] Compared with the prior art, the advantages of the present utility model are as follows: a limiting block and an induction probe are provided. The limiting block is provided with a limiting groove for the steel strip to pass through. When the width or thickness of the steel strip exceeds the limiting groove, the steel strip cannot pass through the limiting groove.

The structure of the present utility model is simple and reasonable, the detection is convenient and accurate, effectively avoiding the abnormal steel strip from flowing into the subsequent process and ensuring the stability of the product quality.

[0020] The following further describes the present utility model in detail with reference to the embodiments of the drawings.

[0021] As Figures 1 to 6As shown in the figure, a device for detecting steel strips includes a limiting block 1 and an induction probe 2. The limiting block 1 is arranged on the conveying line of the steel strip 10 in a position-limited and movable manner. A limiting groove 11 for the steel strip 10 to pass through is formed in the limiting block 1. The width a and thickness b of the limiting groove 11 are the same as the width and thickness of the qualified steel strip 10. The steel strip 10 of the steel strip coil 3 to be detected passes through the limiting groove 11 of the limiting block 1 and is wound on the qualified steel strip coil 4. The induction probe 2 is installed behind the limiting block 1. When the width or thickness of the steel strip 10 exceeds that of the limiting groove 11, the steel strip 10 cannot pass through the limiting groove 11. When the limiting block 1 is driven by the steel strip 10 to move along the conveying direction to the position of the induction probe 2, the induction probe 2 detects the limiting block 1 and outputs an abnormal signal.

[0022] The specific structure is as follows: On the conveying line of the steel strip 10, there are a starting point A and an ending point B for moving and limiting the limiting block 1, and the induction probe 2 is installed at the position of the ending point B. The conveying line of the steel strip 10 is as Figure 1 shown by the arrow. On the conveying line, a first guide wheel 5, a second guide wheel 6, a tensioning wheel 9, a third guide wheel 7 and a fourth guide wheel 8 are arranged in sequence. The steel strip 10 of the steel strip coil 3 to be detected passes upward through the first guide wheel 5 and the second guide wheel 6, then passes downward through the tensioning wheel 9, and then passes upward through the third guide wheel 7 and the fourth guide wheel 8 and is wound on the qualified steel strip coil 4. The limiting block 1 and the induction probe 2 are arranged in sequence on the conveying line between the tensioning wheel 9 and the third guide wheel 7. The induction probe 2 is divided into two types, one is a proximity sensor probe and the other is a photoelectric sensor probe. The device also includes a control system. The output of the induction probe 2 is connected to the control system, and the output of the control system is connected to the actuator and the alarm device. When the induction probe 2 detects the limiting block 1, it outputs an abnormal signal to the control system. The control system immediately stops the machine through the actuator and issues an alarm through the alarm device for the staff to operate: cut off the abnormal steel strip 10 and reset the limiting block 1 to the starting point A.

[0023] The working principle is as follows:

[0024] When the induction probe 2 does not detect any abnormality in the steel strip, the equipment operates normally, as Figure 1 shown; when the thickness of the steel strip is too thick c (as Figure 5 ) or the width is too wide d (as Figure 6 ), the steel strip 10 cannot pass through the limiting groove 11. The limiting block 1 is driven by the steel strip 10 to move from A to B along the conveying direction, as Figure 2 shown. The induction probe 2 detects the limiting block 1 and outputs an abnormal signal to the control system. The control system immediately stops the machine and issues an alarm for the staff to operate: cut off the abnormal steel strip 10, reset the limiting block 1 to the starting point A, and restart the machine to run.

[0025] The advantages of the present utility model are as follows:

[0026] 1. It doesn't need to be in direct contact with the steel strip, effectively avoiding equipment wear and interference;

[0027] 2. The proximity sensor probe can quickly detect the approach of an object, and the photoelectric sensor probe can quickly capture the change of the optical signal. Therefore, the response speed of the equipment is extremely fast;

[0028] 3. It has strong anti-interference ability and can work normally in harsh environments, greatly enhancing the applicability of the equipment,

[0029] significantly increasing the application scenarios.

[0030] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
