[0026] It should be noted that the balance wheel sorting machine 2 is an existing automatic sorting device, which is widely used in warehouses of logistics, express delivery, e-commerce and other industries, and is used for quickly and accurately sorting different articles to specified positions. The core component of the sorting machine is a swing type conveying wheel, and through the swing conveying wheel, the articles can be flexibly guided into different sorting channels.

[0027] In the embodiment, the warning device 3 comprises a horizontal rod 31, a spring 32 and a movable plate 33; the horizontal rod 31 is arranged above the conveying belt 1, a height sensor 34 is installed on the horizontal rod 31, and the height sensor 34 is connected with a control system of the balance wheel sorting machine 2; one end of the spring 32 is connected with the horizontal rod 31, and the other end of the spring 32 is connected with the movable plate 33 located below the horizontal rod 31; when the spring 32 is in a natural state, the lower end of the movable plate 33 is flush with the upper surface of a normal height gypsus board 5, so that when the conveying belt 1 conveys the gypsus boards 5 to pass through the position directly below the movable plate 33, if the gypsus board 5 is damp, curved or deformed and bulges to cause the height of the gypsus board 5 to be higher than the height of the normal gypsus board 5, the movable plate 33 is lifted to cause the height sensor 34 to sense the height change of the movable plate 33, and the height change is converted into an electric signal; when the height of the movable plate 33 is higher than the height threshold set by the height sensor 34 (when the height of the gypsus board 5 is too high), the height sensor 34 outputs an electric signal to the control system of the balance wheel sorting machine 2, the control system controls the balance wheel sorting machine 2 to turn to the belt supporting part 11 and keep the conveying state for a period of time, and the gypsus board 5 that is too high is conveyed to the belt supporting part 11 by the balance wheel sorting machine 2.

[0028] Specifically, the horizontal rod 31 is square, a square sleeve plate 35 is integrally connected with the lower surface of the horizontal rod 31, the upper end of the movable plate 33 is inserted into the sleeve plate 35, and the height sensor 34 and the spring 32 are arranged in the sleeve plate 35; the sleeve plate 35 is arranged on one hand to protect the height sensor 34 and the spring 32 from being disturbed by the external environment, and on the other hand to horizontally limit the movable plate 33 to prevent the movable plate 33 from horizontally moving to cause the spring 32 to bend under the horizontal force of the gypsus board 5.

[0029] More specifically, the number of springs 32 is two, two springs 32 are arranged in the two sides of the sleeve plate 35 respectively, and are axisymmetric with the center line of the movable plate 33 as the axis of symmetry, so that the elastic force of the spring 32 received by the movable plate 33 is evenly distributed; the height sensor 34 is arranged between the two springs 32 and located on the center line of the movable plate 33, so as to improve the accuracy of height detection.

[0030] Specifically, the lower end of the movable plate 33 is arc-shaped, and preferably the entire lower end surface of the movable plate 33 is rounded, so that the contact point between the gypsum board 5 and the movable plate 33 can move downward along the arc surface when the gypsum board 5 advances, so that the movable plate 33 is more easily lifted by the gypsum board 5.

[0031] Further, the early warning device 3 further comprises two support rods 36, and the two support rods 36 are respectively fixedly connected on the two sides of the conveying belt 1 through screws, and the two ends of the cross bar 31 are respectively arranged on the two support rods 36 through up-down movement adjustment, so that the height of the cross bar 31 is adjusted, and the lower end of the movable plate 33 can be flush with the upper surface of the gypsum board 5 of different heights, thereby improving the adaptability.

[0032] Specifically, the support rod 36 is provided with a first strip-shaped hole 361 and a second strip-shaped hole 362 which are longitudinally and transversely intersected and communicated, the two ends of the cross bar 31 are respectively arranged in the two first strip-shaped holes 361, the second strip-shaped hole 362 is provided with a bolt 37 which penetrates the cross bar 31, and one end of the bolt 37 is threadedly connected with a nut 38; in use, the cross bar 31 can be moved up and down along the support rod 36 by loosening the nut 38, so as to adjust the height of the cross bar 31; by tightening the nut 38, the screw cap of the bolt 37 cooperates with the nut 38 to be clamped and fixed on the support rod 36, so as to limit the up-down movement of the cross bar 31, thereby realizing the up-down movement adjustment of the cross bar 31.

[0033] The use method or working principle of the utility model is as follows:

[0034] Before the gypsum board 5 is conveyed to the ink-jet printer, the nut 38 is loosened, the crossbar 31 is moved up and down along the support rod 36 to adjust the height of the crossbar 31, so that when the spring 32 is in a natural state, the lower end of the movable plate 33 is flush with the upper surface of the normal height gypsum board 5, after adjustment, the nut 38 is tightened to make the screw cap of the bolt 37 clamped and fixed on the support rod 36 to limit the up and down movement of the crossbar 31; when the conveying belt 1 conveys the gypsum board 5 to the position directly below the movable plate 33, if the gypsum board 5 is damp and curved or deformed and bulging, so that its height is higher than the normal height of the gypsum board 5, then the gypsum board 5 will lift the movable plate 33 and compress the spring 32, so that the height sensor 34 senses the height change of the movable plate 33 and converts it into an electric signal; when the height of the movable plate 33 is higher than the height threshold set by the height sensor 34 (when the height of the gypsum board 5 is too high), the height sensor 34 will output an electric signal to the control system of the swing wheel sorting machine 2, and the control system will control the swing wheel sorting machine 2 to turn to the conveying belt 11 and keep conveying for a period of time, until the gypsum board 5 with too high height is conveyed to the conveying belt 11 by the swing wheel sorting machine 2; after the gypsum board 5 with too high height passes through the early warning device 3, the movable plate 33 returns to the original state under the action of the spring 32, if the height of the next gypsum board 5 is lower than the height threshold set by the height sensor 34, then the gypsum board 5 will be normally conveyed along the conveying belt 1 to the position below the nozzle 4 of the ink-jet printer for ink-jet printing, so as to effectively prevent the nozzle 4 from being impacted.
