DETAILED DESCRIPTION

[0021] The present disclosure will be further described below in conjunction with the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the related content, and not to limit the present disclosure. In addition, it should be noted that, for the convenience of description, only the parts related to the present disclosure are shown in the drawings.

[0022] Fig. 1 It is a structural schematic diagram of a paperboard conveying deviation rectification mechanism;

[0023] Fig. 2 It is a side view of a paperboard conveying deviation rectification mechanism;

[0024] Fig. 3 It is a sectional view of a paperboard conveying deviation rectification mechanism;

[0025] As Figs. 1-3 shown, a paperboard conveying deviation rectification mechanism of the present disclosure can include detection mechanism, support mechanism, deviation rectification mechanism and other components;

[0026] As Figs. 1-3 shown, the detection mechanism includes mounting plate 1, telescopic rod 2, U-shaped frame 3, spring 4, detection roller 5, damping telescopic rod 6, pressure sensor 7;

[0027] Two mounting plates 1 are arranged in parallel, each group of two telescopic rods 2 is installed on the lower surface of the corresponding mounting plate 1, each U-shaped frame 3 is installed at the lower end of the corresponding group of telescopic rods 2, each spring 4 is sleeved on the corresponding telescopic rod 2, each detection roller 5 is rotatably installed between the inner side surfaces of the corresponding U-shaped frame 3, each damping telescopic rod 6 is installed on the center of the upper surface of the corresponding U-shaped frame 3, and each pressure sensor 7 is installed on the center of the lower surface of the corresponding mounting plate 1 and directly above the damping telescopic rod 6;

[0028] The distance between the two detection rollers 5 is adjusted by the support mechanism to be the same as the width of the paperboard. When the paperboard moves on the conveyor belt, if there is no deviation, the paperboard passes between the two detection rollers 5. If the paperboard deviates, the advancing paperboard will contact the detection roller 5 on the same side and then press it upwards. The rising detection roller 5 compresses the spring 4 and drives the damping telescopic rod 6 to rise and press the pressure sensor 7. When the pressure sensor 7 is pressed, the paperboard with an edge deviates. At the same time, the pressure sensor 7 can limit the rising damping telescopic rod 6. The continuously rising damping telescopic rod 6 will shrink itself, thereby adapting to paperboards of various thicknesses. When detecting other thicknesses, there is no need to adjust in advance, reducing the labor of workers. After the paperboard passes through the detection roller 5, the compressed spring 4 rebounds to restore its position;

[0029] As shown in Figs. 1-3 , the support mechanism includes a U-shaped plate 8, a hollow groove 9, a moving seat 10, a moving groove 11, a bidirectional screw 12, a motor 13, a threaded seat 14, and a first electric push rod 15.

[0030] The U-shaped plate 8 is arranged directly above the two mounting plates 1. The two hollow grooves 9 are formed on the two sides of the mounting plates 1. The moving seat 10 is installed on the inner top surface of the U-shaped plate 8 and is directly above the two mounting plates 1. The moving groove 11 is formed on the lower surface of the moving seat 10. The motor 13 is installed at one end of the moving seat 10. The bidirectional screw 12 is rotatably installed in the moving groove 11 and has an end fixedly connected with the driving end of the motor 13. The two threaded seats 14 are arranged on the two threads of the bidirectional screw 12 and are fixedly connected with the two mounting plates 1. The first electric push rod 15 is installed on the upper surface of the U-shaped plate 8 and has an extension arm end penetrating the U-shaped plate 8 and fixedly connected with the moving seat 10.

[0031] Before use, the first electric push rod 15 is elongated to drive the moving groove 11 to descend, thereby driving the detection mechanism to descend until the two detection rollers 5 contact the upper surface of the conveyor belt. At the same time, the motor 13 is operated to drive the bidirectional screw 12 to rotate and drive the two detection rollers 5 to approach each other, thereby adjusting the distance between the two detection rollers 5, so that the device can adapt to paperboards of various widths.

[0032] As shown in Figs. 1-3 , the deviation correction mechanism includes an L-shaped plate 16, a second electric push rod 17, and a deviation correction plate 18.

Each deviation correction plate 18 is installed on the extension arm end of the corresponding second electric push rod 17 penetrating the L-shaped plate 16.

[0034] When the detection mechanism detects that the paperboard deviates, the two second electric push rods 17 are extended to drive the two deviation correction plates 18 to approach each other until the advancing paperboard is pushed to the central position of the conveying belt, deviation correction is realized, and then the two second electric push rods 17 are shortened to drive the two deviation correction plates 18 to restore the position, and the deviation correction is realized.
