Description

Technical Field

[0001] This utility model relates to the technical field of surface defect detection devices, specifically a surface defect detection device for cold-rolled stainless steel coils. Background Technology

[0002] In modern industrial production, cold-rolled stainless steel coils are widely used in various fields such as building decoration, medical devices, and food processing. As market demands for the quality of cold-rolled stainless steel coils continue to increase, the detection of surface defects has become a crucial step in the production process.

[0003] Patent document CN219965999U discloses a surface defect detection device for cold-rolled stainless steel coils, comprising two sets of support frames. Each support frame includes a front rod, a rear rod, and a connecting rod. A connecting rod is welded to the bottom between the front rod on the front side and the rear rod on the rear side of the support frame, and the top of the front rod is lower than the top of the rear rod. A crossbeam is welded between the front rods on the front sides of the two sets of support frames. The technical solution of this application can prevent strip steel from deviating and breaking due to drastic stress changes caused by rapid cooling when exiting the annealing furnace; prevent cooling water in the annealing furnace area from following the strip steel into the dryer, resulting in water stains on the surface of the strip steel after exiting the annealing furnace, thus preventing surface quality defects; and solve the surface quality problems of strip steel such as scratches caused by uneven contact between the roller system and the strip steel, greatly improving the first-grade yield of the product.

[0004] However, this device lacks the ability to straighten and level the steel strip by passing it through different thicknesses before testing, thereby increasing the accuracy of the test. Utility Model Content

[0005] The main purpose of this invention is to provide a surface defect detection device for cold-rolled stainless steel coils, which can effectively solve the problem in the background art where the unevenness of the steel strip itself affects the detection process and lowers the detection standards.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A surface defect detection device for cold-rolled stainless steel coils includes an instrument, a conveyor frame fixedly connected to one side of the instrument, an adjustment mechanism fixedly connected to both sides of the conveyor frame, rollers rotatably connected to the top of both sides of the adjustment mechanism, a straightening mechanism mounted above the rollers, the adjustment mechanism including connecting rings fixedly connected to both sides of the conveyor frame, a hydraulic telescopic rod fixedly connected to the bottom surface of the connecting rings, an mounting ring fixedly connected to the bottom surface of the hydraulic telescopic rods, a drive motor mounted on the right side of the mounting ring, and a straightening wheel mounted above the rollers, with multiple straightening frames mounted a short distance away from one side of the straightening wheel.

[0008] Preferably, one side of the mounting ring is rotatably connected to an adapter, and the other side of the adapter is fixedly connected to one side of the drive motor.

[0009] Preferably, the multi-straightening frame includes a straightening roller A installed not far from the straightening wheel, and a rotating connector is rotatably connected to one side of the straightening roller A.

[0010] Preferably, a rotating motor is fixedly connected to one side of the rotating connector, and a hydraulic lifting frame is installed at the bottom of one side of the rotating connector.

[0011] Preferably, a straightening roller B is installed at the bottom of the hydraulic lifting frame, and both sides of the straightening roller B are rotatably connected to the inner sides of the conveyor frame.

[0012] Preferably, an alarm is fixedly connected to the top surface of the middle part of the detector, and a PLC controller is fixedly connected to one side of the middle part of the detector.

[0013] Preferably, the bottom of the conveyor frame is fixedly connected to a support leg, and the bottom of the support leg is equipped with an anti-slip pad.

[0014] Preferably, a rotating shaft is fixedly connected to the middle of the straightening roller A, and the rotating shaft is rotatably connected to one side of the rotating connector.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. This utility model, through the setting of the adjustment mechanism, has a connecting ring installed inside one end of the conveyor frame when the device is to be used. A roller is installed inside the connecting ring, and a hydraulic telescopic rod is installed at the bottom of the connecting ring. The hydraulic telescopic rod can adjust the height up and down with the roller at the bottom, which plays the role of adjusting according to the thickness of the external steel strip. This avoids the problem that the straightening is not sufficient due to the inability to adjust according to the thickness of the external steel strip. The bent steel strip may also cause the distance between the detection probe and the surface of the steel strip to change, affecting the stability and accuracy of the detection signal.

[0017] 2. This utility model, through the setting of a straightening mechanism, installs a straightening wheel above the rollers when the device is to be used. The two wheels cooperate to perform primary straightening of the steel strip. Then, straightening rollers A and B are installed behind the two wheels to perform multi-stage straightening and leveling of the steel strip. This plays a role in adjusting the steel strip to be flat, increasing the accuracy of detection, and avoiding insufficient signal detection due to the bending and depression of the steel strip surface, which would affect the detection and prevent some problems and defects from being detected, leaving hidden dangers.

An mounting ring 303 is fixedly connected to the bottom surface of the hydraulic telescopic rod 302. A drive motor 304 is mounted on the right side of the mounting ring 303.

[0026] A connecting ring 301 is installed inside one end of the conveyor frame 2. A roller 4 is installed inside the connecting ring 301. A hydraulic telescopic rod 302 is installed at the bottom of the connecting ring 301. The hydraulic telescopic rod 302 can adjust the height up and down with the roller 4 at the bottom.

[0027] Please see Figure 3 The straightening mechanism 5 includes a straightening wheel 501 mounted above the roller 4, and multiple straightening frames 502 mounted not far from one side of the straightening wheel 501.

[0028] A straightening roller 501 is installed above roller 4. The two rollers work together to perform primary straightening of the steel strip. Then, straightening rollers A15 and B10 are installed behind the two rollers to perform multi-stage straightening and leveling of the steel strip.

[0029] Please see Figure 1-4 One side of the mounting ring 303 is rotatably connected to a connector 6, and the other side of the connector 6 is fixedly connected to one side of the drive motor 304. The multi-straightening frame 502 includes a straightening roller A15 installed not far from the straightening wheel 501.
