Description

Technical Field

[0001] This utility model belongs to the field of stainless steel quality monitoring technology, and specifically relates to an auxiliary detection device for the surface quality of cold-rolled stainless steel strip. Background Technology

[0002] Stainless steel strip rolling belongs to the metallurgical industry, and stainless steel products are widely used. Therefore, the surface quality of stainless steel strip is particularly important, as it directly affects the appearance of stainless steel products. Especially now that there are many types of stainless steel products and the specifications are constantly being improved, the surface quality requirements of stainless steel strips used as raw materials for cold-rolled stainless steel products are constantly increasing. The main factors affecting the surface quality of stainless steel strips are dust, residues, and rolling oil residues.

[0003] According to the standard GB / T 3280-2015-Stainless Steel Cold Rolled Sheet and Strip, the surface quality of stainless steel strip is inspected visually. Of course, depending on the convenience provided by different production methods, there are also monitoring methods such as wiping. For example, the existing technical announcement number CN 214066971 U provides a method of monitoring using test paper.

[0004] Based on national standards and existing technologies, the applicant has provided a technical solution for monitoring using a reflector. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an auxiliary detection device for the surface quality of cold-rolled stainless steel strip. The application of a reflector can help observe the surface quality of the bottom surface of the stainless steel plate.

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

[0007] An auxiliary inspection device for the surface quality of cold-rolled stainless steel strip includes a support frame, a fixed frame, a first electric actuator, a mounting frame, a reflector, and a support mechanism. The fixed frame is located above the support frame, and the first electric actuator is located on the support frame with its top shaft fixedly connected to the fixed frame. The mounting frame and support mechanism are located on the fixed frame, with the mounting frame angled on the fixed frame. One end of the mounting frame is located on the support mechanism, and the other end is rotatably connected to the fixed frame. The reflector is fixed on the mounting frame and located below the stainless steel strip. The height of the fixed frame is adjusted by controlling the first electric actuator, and the reflection angle of the reflector is adjusted by controlling the tilt angle of the mounting frame through the support mechanism, facilitating observation by the operator.

[0008] The fixed frame is equipped with a support arm and a guide shaft, and the guide shaft is slidably connected to the support frame.

[0009] The mounting bracket includes a fixed arm, a first connecting shaft, and a second connecting shaft that are fixedly connected to each other. The first connecting shaft is rotatably connected to the support arm. The fixed arm is provided with a through groove and a rack, with the rack located on one side of the through groove.

[0010] The support mechanism includes a second electric actuator, an adjusting arm, a fixed shaft, and a horizontal shaft. The two ends of the fixed shaft are fixed to the fixed frame via bearing seats. The two ends of the fixed shaft are fixedly connected to the adjusting arm, and the other end of the adjusting arm is fixedly connected to the horizontal shaft, which is located below the mounting frame. The base of the second electric actuator is hinged to the fixed frame, and the top end of the second electric actuator is rotatably connected to one end of the horizontal shaft. The second electric actuator pushes the adjusting arm to rotate, thereby changing the height of one end of the mounting frame by pushing it with the horizontal shaft, thus achieving the adjustment of the tilt angle.

[0011] The mounting frame is equipped with a blowing mechanism and a power mechanism. The blowing mechanism is located above the reflector and is driven by the power mechanism to clean the surface of the reflector. The blowing mechanism includes a U-shaped frame and an air pipe. The U-shaped frame has support wheels at both ends and an air nozzle at the bottom. The air nozzle is connected to the air pipe, which is fixed to the U-shaped frame by a fixed seat. One end of the air pipe is equipped with a rotary joint to connect to an external air source. The U-shaped frame also has a rotatably connected brush roller. One end of the brush roller has a through shaft with a gear meshing with a rack. The through shaft on the brush roller is located in a through groove, and the support wheels are supported by a fixed arm. The outer ring of the brush roller is wrapped with non-woven fabric.

[0012] The power mechanism includes a motor, a drive shaft, a chain, a ring clamp, and a rotating shaft. The drive shaft is rotatably connected to fixed arms at both ends, and a sprocket is located at one end of the drive shaft. The rotating shaft is mounted on the fixed arm at one end of the through groove, rotatably connected to the fixed arm, and also has a sprocket on it. The chain connects the sprocket at the end of the drive shaft and the sprocket at the end of the rotating shaft. The motor is fixed to the fixed arm via a motor mount, and the motor shaft is connected to the rotating shaft. The ring clamp is fixed to the chain and rotatably connected to the through shaft. The motor drives the chain for transmission, and the ring clamp and chain pull the through shaft to slide within the through groove, thereby driving the blowing mechanism to slide up and down along the through groove. The rotation and brushing effect of the brush roller is achieved through the cooperation of the gear and rack.

[0013] The advantages of this utility model compared with the prior art are as follows:

[0014] In this solution, a reflector is set at an angle, which uses the principle of light reflection to allow staff to observe the surface condition of the bottom side of the stainless steel strip from the observation area on one side. Therefore, the surface quality of the stainless steel strip can be observed at the same time on both the front and bottom sides. Secondly, the tilt angle of the mounting frame and the reflector can be adjusted by the second electric push rod in the support mechanism to make the reflection effect adapt to the observation requirements of staff at different heights.

[0015] Furthermore, the surface of the reflector can be cleaned by the motor-driven blowing mechanism moving up and down along the through groove; the blowing effect of the brush roller in combination with the air nozzle can greatly improve the overall cleaning effect. Attached Figure Description

[0035] The mounting frame 4 is equipped with a blowing mechanism 6 and a power mechanism 7. The blowing mechanism 6 is located above the reflector 5, and the power mechanism 7 drives the blowing mechanism 6 to clean the surface of the reflector 5.

[0037] An auxiliary inspection device for the surface quality of cold-rolled stainless steel strip, the working process of which is as follows:

[0038] The stainless steel strip 9 passes over the reflector 5. First, a work observation area 10 is set up on one side of the auxiliary monitoring device. The staff stands here to observe the front of the stainless steel strip 9 and the bottom surface of the stainless steel strip 9 as reflected by the reflector, and visually inspects the stainless steel strip 9 accordingly.

[0039] The staff members have different heights, so the viewing angles for observing the front and bottom of the stainless steel strip 9 are different. The reflection angle of the uniform and fixed reflector 5 may not be suitable for all staff members; therefore, the problem of adaptability is solved by adjustment.

[0040] The height of the mounting bracket 2 can be controlled by the first electric push rod 3, and the height of one end of the mounting bracket 4 can be pushed and controlled by the second electric push rod 81, thereby realizing the angle of the reflector 5 to be installed at an angle, and finally realizing the adjustment of the reflection angle. Furthermore, the motor 71 can be used to provide power, the chain 73 can be used for transmission and cooperate with the ring hoop 74 to drive the blowing mechanism 6 to slide up and down along the through groove 412. The air nozzle 63 blows the surface of the reflector 5, and then the brush roller 64 is rotated by the cooperation of the gear 642 and the rack 411 to improve the brushing effect. The combination of blowing and brushing can keep the surface of the reflector 5 clean for a long time, which is conducive to ensuring the surface quality inspection effect of the stainless steel strip 9. It is worth noting that the motor 71 here drives the blowing mechanism 6 to move up and down in both forward and reverse directions.
