DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

The bottom end of the push rod of the electric telescopic rod 6 is fixedly connected to a fixed plate, and the front end of the fixed plate is fixedly connected to a plurality of fixed rods 7. A movable rod 8 is movably connected through the upper and lower ends of the fixed rod 7, and a rotating rod 9 is installed at the bottom of the movable rod 8. An erasable marker 10 is installed at the top of the movable rod 8 through a mounting seat, and a bracket is fixedly connected to one side of the movable rod 8. A mounting box is installed at the top of the bracket through bolts, and a drawing paper 11 matching the erasable marker 10 is provided on the side of the bracket close to the erasable marker 10. A plurality of conveying rollers 3 are rotatably installed inside the detection frame 1 and below the movable rod 8, and a steel plate body 14 is provided on the top surface of the conveying roller 3, and the top surface of the steel plate body 14 is in contact with the outer circle of the rotating rod 9.

[0025] In this embodiment, a plurality of conveying rollers 3 are arranged at equal intervals in the detection frame 1, and the outer ring of the conveying roller 3 is flush with the top surface of the feed conveyor belt 2. A feeding motor 1 and a feeding motor 2 are installed on one side of the detection frame 1. The feed motor shaft is connected to the rotating shaft of the feed conveyor belt 2. The shaft of the feed motor 2 is connected to a plurality of conveying rollers 3 through a transmission belt. The feed conveyor belt 2 is driven to rotate by the rotation of the feed motor 1 shaft, and then the feed motor 2 shaft is driven to rotate to drive the plurality of conveying rollers 3, so as to facilitate the conveying of the steel plate body 14.

[0026] In this embodiment, the rear end of the detection frame 1 is fixedly connected to a discharge frame 15, and a reversing conveyor belt 16 is installed inside the discharge frame 15 through a roller. Electric telescopic rods 17 are movably installed on both sides of the discharge frame 15, and the electric telescopic rods 17 are connected to both sides of the roller located at the rear of the reversing conveyor belt 16. A reversing motor is installed on one side of the discharge frame 15, and the reversing motor is connected to the reversing conveyor belt 16 roller. The reversing motor is set to drive the reversing conveyor belt 16 to rotate, so as to facilitate the transportation of the steel plate body 14 after detection.

[0027] In this embodiment, the push rod of the electric telescopic rod 17 is movably connected to the two sides of the roller, and movable grooves matching the rollers are provided on both sides of the discharging rack 15. A discharging conveyor belt 18 is installed at the upper position inside the discharging rack 15, and a discharging conveyor belt 2 19 is installed at the lower position inside the discharging rack 15. By extending and retracting the push rod of the electric telescopic rod 17, the angle of the reversing conveyor belt 16 can be adjusted conveniently, so that material can be discharged as needed.

[0028] In this embodiment, the top surfaces of the discharging conveyor belt 18, the reversing conveyor belt 16 and the conveying roller 3 are flush, and two discharging motors are installed on one side of the discharging frame 15. The shafts of the two discharging motors are respectively connected to the discharging conveyor belt 18 and the discharging conveyor belt 2 19. The qualified steel plate body 14 is conveyed out through the set discharging conveyor belt 18, and the unqualified steel plate body 14 is conveyed out through the set discharging conveyor belt 2 19, so that the qualified steel plate body 14 and the unqualified steel plate body 14 can be classified and discharged for easy classification.

[0029] In this embodiment, a contact switch matching the erasable marker pen 10 is provided at the bottom end of the installation box 12, a mounting groove is opened inside the fixed rod 7, the outer ring of the movable rod 8 is fixedly connected with a ring plate in the mounting groove, a spring is installed in the mounting groove, and the upper and lower ends of the spring are respectively fixedly connected to the ring plate and the fixed rod 7. The erasable marker pen 10 is driven to rise by the movable rod 8, thereby squeezing the control switch on the installation box 12, which is convenient for detecting the flatness. At the same time, the erasable marker pen 10 is used to draw lines on the drawing paper 11, which is convenient for observing the height of the highest protrusion of the steel plate body 14.

[0030] In this embodiment, a paint storage tank 13 is installed at the rear position of the outer ring of the movable rod 8, and a nozzle is provided at the bottom of the paint storage tank 13, and an electromagnetic valve is provided at the connection between the paint storage tank 13 and the nozzle. The scrubbable paint sprayed from the paint storage tank 13 is convenient for marking unqualified parts on the steel plate body 14.

[0031] It should be noted that the utility model is a steel surface flatness detection device. When in use, first, the external conveying device can be connected to the front of the detection frame 1 as needed, so that the steel plate body 14 can be conveyed to the feed conveyor belt 2. When detecting, the feeding motor 1 and the feeding motor 2 can be started as needed, and the discharging motor and the reversing motor can be started at the same time, so that the feed motor 1 shaft can rotate to drive the feed conveyor belt 2 to rotate, and the steel plate body 14 can be transported. Then, the feed motor 2 shaft rotates to drive a number of conveying rollers 3 to rotate, and the steel plate body 14 is conveyed. When the steel plate body 14 moves to the bottom of a number of rotating rods 9, the rotating rods 9 contact the upper surface of the steel plate body 14.

[0032] When the surface of the steel plate body 14 is raised, the movable rod 8 is lifted up. Since the erasable marker 10 is fixedly installed above the movable rod 8 and the erasable marker 10 is located below the mounting box 12, the erasable marker 10 can be driven to rise through the movable rod 8, thereby squeezing the control switch on the mounting box 12, thereby opening the paint storage tank 13 and the electric telescopic rod 2 17, and turning off the feeding motor 1, spraying the scrubbable paint through the paint storage tank 13, marking the unqualified parts, and retracting the push rod of the electric telescopic rod 2 17 to drive the reversing conveyor belt. 16 is tilted until the reversing conveyor belt 16 cooperates with the discharging conveyor belt 19, so that when the steel plate body 14 is on the reversing conveyor belt 16, the reversing conveyor belt 16 transfers the steel plate body 14 to the discharging conveyor belt 19, and the electric telescopic rod 17 is set to delay for ten seconds. After ten seconds, the electric telescopic rod 17 is reset again, driving the reversing conveyor belt 16 to be flush with the discharging conveyor belt 1 18 again, which is convenient for subsequent use. At the same time, the erasable marker 10 is used to draw lines on the drawing paper 11, which is convenient for observing the height of the highest protrusion of the steel plate body 14;

[0033] When the flatness of the steel plate body 14 is qualified, the movable rod 8 will not drive the erasable marker 10 to rise to the height that touches the installation box 12, and the feeding motor 1 and the feeding motor 2 will not be turned off, so that the steel plate body 14 is transported through the conveying roller 3, the feed conveyor belt 2, the reversing conveyor belt 16, and the discharge conveyor belt 18 for discharge, thereby conveying the qualified plate out. Through the above steps, the qualified steel plate body 14 and the unqualified steel plate body 14 can be classified and discharged.

[0034] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
