[0002] Color steel plate, also known as color coated steel plate, is a kind of steel plate with an organic coating. Color steel plates are widely used as lightweight building materials in the fields of construction, industry, etc. It uses cold-rolled substrate, hot-dip galvanized substrate or electro-galvanized substrate as raw materials, and through surface pretreatment and roll coating process, one or more layers of liquid coatings are coated and baked and cooled. Color steel plates have the advantages of strong corrosion resistance, light weight, good aesthetics, convenient installation, heat preservation and heat insulation, etc. Its coatings are rich and diverse, with bright colors, which can meet the appearance requirements of different building designs.

[0003] During the processing of color steel plates, a conveyor belt is needed to convey the color steel plates into the spraying room for spraying. During the conveying process, the color steel plates on the conveyor belt may deviate. After the color steel plates on the conveyor belt deviate, they will deviate from the spraying heads in the spraying room, resulting in deviation of the spraying position and affecting the product quality. Therefore, an automatic deviation rectification device for color steel plate conveying is proposed. Content of the Utility Model

Specific embodiments

[0021] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] As Figure 1 Figure 2 shown, the automatic deviation rectification device for color steel plate transportation includes a device frame 1. A cylinder 4 is provided at the upper end of the device frame 1. The output end of the cylinder 4 is connected with a sliding seat 3. An adjusting roller 5 is movably installed on the sliding seat 3. A connecting shaft 2 is fixedly installed on the device frame 1. An adjustment mechanism 6 is provided between the device frames 1. The adjustment mechanism 6 includes a positioning bracket 601 fixed on the device frame 1. A positioning guide rod 603 is fixedly installed on the positioning bracket 601. A motor base 605 is fixedly installed at the middle position of the positioning guide rod 603. A servo motor 606 is fixedly installed on the motor base 605. Trapezoidal lead screws 604 are movably installed on both sides of the motor base 605. A lead screw slider 602 is provided on the trapezoidal lead screw 604. A deviation rectification mechanism 7 is connected to the lead screw slider 602. By using the adjustment mechanism 6 and the deviation rectification mechanism 7 in cooperation, color steel plates of different widths can be corrected to the middle position of the conveyor belt.

[0023] As Figure 4 shown, the deviation rectification mechanism 7 includes a roller frame 701 fixed on the lead screw slider 602. A deviation rectification roller 702 is movably installed in the roller frame 701. A laser rangefinder 704 and a reflector 705 are provided on the roller frame 701. A positioning shaft 707 is provided at the end of the roller frame 701. A threaded telescopic rod 706 is movably installed on the positioning shaft 707. The deviation rectification mechanism 7 further includes a movable shaft 703 movably installed on the roller frame 701, and a bearing is provided on the movable shaft 703.

[0024] Specifically, when the color steel plate with a wider front and narrower rear on the roller frame body 701 of the deviation rectifying mechanism 7 passes through the roller frame body 701, the deviation rectifying rollers 702 will guide the color steel plate on the conveyor belt to move to the middle position, so that the color steel plate can correctly enter the spray painting chamber. Moreover, the threaded telescopic rod 706 will provide support for the end of the roller frame body 701, reduce the pressure on the positioning guide rod 603, and extend the service life of the positioning guide rod 603.

[0025] As Figure 3 shown, an adjusting mechanism 6 is provided between the device frame bodies 1. The adjusting mechanism 6 includes a positioning bracket 601 fixed on the device frame body 1. A positioning guide rod 603 is fixedly installed on the positioning bracket 601. A motor seat 605 is fixedly installed at the middle position of the positioning guide rod 603. A servo motor 606 is fixedly installed on the motor seat 605. Trapezoidal lead screws 604 are movably installed on both sides of the motor seat 605. A lead screw slider 602 is provided on the trapezoidal lead screw 604. Helical gears 607 are provided at the ends of the trapezoidal lead screw 604 and the servo motor 606, and the helical gears 607 are meshed with each other in pairs.

[0026] Specifically, the servo motor 606 can be driven to drive the trapezoidal lead screw 604 to rotate. After the trapezoidal lead screw 604 rotates, the lead screw slider 602 moves left and right. After the lead screw slider 602 moves left and right, it will drive the roller frame body 701 to move left and right, adjust the distance between the deviation rectifying rollers 702. Moreover, during the left and right movement of the roller frame body 701, the laser rangefinder 704 and the reflector 705 can cooperate with each other to monitor the distance between the deviation rectifying rollers 702 in real time, which is convenient for users to accurately adjust the distance between the deviation rectifying rollers 702 and correct color steel plates with different widths to the middle position of the conveyor belt.

[0027] It should be noted that the present utility model is an automatic deviation rectification device for color steel plate conveying. In actual use, first, the entire device is set at the end of the conveyor belt. When the conveyor belt conveys the color steel plate into the painting room, it will pass through the deviation rectification mechanism 7. The roller frame body 701 on the deviation rectification mechanism 7 is wider at the front and narrower at the rear. When the color steel plate passes through the roller frame body 701, the deviation rectification roller 702 will guide the color steel plate on the conveyor belt to move to the middle position, so that the color steel plate can enter the painting room correctly. And during the process of guiding the color steel plate, the color steel plate will apply pressure to the deviation rectification roller 702 on the roller frame body 701, and the pressure applied to the deviation rectification roller 702 will be transmitted to the positioning guide rod 603, causing the positioning guide rod 603 to deform. Before use, one end of the threaded telescopic rod 706 can be connected to the fixed roller frame body 701 and the other end to the connecting shaft 2, using the threaded telescopic rod 706 to provide support for the end of the roller frame body 701, reducing the pressure on the positioning guide rod 603 and extending the service life of the positioning guide rod 603. At the same time, the servo motor 606 can be started. Since bevel gears 607 are provided at the ends of both the trapezoidal lead screw 604 and the servo motor 606, and the bevel gears 607 are meshed with each other in pairs, after starting the servo motor 606, it will drive the trapezoidal lead screws 604 on both sides of the motor base 605 to rotate. After the trapezoidal lead screws 604 on both sides of the motor base 605 rotate, the lead screw sliders 602 move left and right. After the lead screw sliders 602 move left and right, they will drive the roller frame body 701 to move left and right. During the process of the roller frame body 701 moving left and right, the laser rangefinder 704 and the reflector 705 can cooperate with each other to monitor the distance between the deviation rectification rollers 702 in real time, so as to accurately adjust the distance between the deviation rectification rollers 702, facilitating the rectification of color steel plates with different widths to the middle position of the conveyor belt.

[0028] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
