Description

Technical Field

[0001] The utility model relates to the technical field of carton production, in particular to a device for screening warped paperboards used in carton processing. Background Art

[0002] During the carton processing process, some raw cardboards will bend due to internal stress and uneven moisture distribution. These warped cardboards are prone to positional displacement when processed into cartons, resulting in deviations in the processing of the cardboard and an increase in the scrap rate of the final finished cartons.

[0003] The utility model patent with patent application publication number CN 220444455 U discloses a device for screening warped cardboard for carton processing, including a bottom plate, a conveyor belt provided on the bottom plate, a top plate provided on the upper side of the conveyor belt, four support rods connected between the top plate and the bottom plate, a detection component provided at the bottom of the top plate, a motor provided at the top of the top plate, the output shaft of the motor passes through the top plate and is connected to the detection component, and a screening component is provided on one side of the conveyor belt. The utility model can use the detection component to perform two warping detections on the cardboard in the parallel transportation direction and the perpendicular transportation direction, fully detect the warping condition of the cardboard, and ensure the accuracy of the measurement results; after the measurement is completed, the screening component can automatically screen out the warped cardboard, without the need for manual detection and screening, thereby reducing labor costs and improving screening efficiency.

[0004] However, the above device still has some shortcomings in actual use. The most obvious one is that the sizes of different types of cardboards are often different and the difference is large. When the size of the cardboard is too small, the infrared rangefinder of the device lacks a limit device to match the moving range of the rangefinder with the size of the cardboard. The infrared rangefinder will also measure the distance between the rangefinder and the conveyor belt, which may result in erroneous detection results and cause errors. In addition, the device is transported to the lower side of the detection component through the conveyor belt, and it cannot be guaranteed that the cardboard is moved directly under the detection component. The operator needs to manually straighten and align it, which is difficult to operate and wastes a lot of time, reducing the operator's production efficiency.

[0005] Therefore, it is necessary to invent a warped cardboard screening device for carton processing to solve the above problems. Utility Model Content

[0024] like Figure 2 As shown, in the present disclosure, the operating table assembly 1 includes an operating table body 11, a fixed frame 12, a first sliding limit groove 13, a side panel 14, a motor 15 and a conveyor belt 16, wherein the fixed frame 12 is fixedly connected to the top of the operating table body 11, the first sliding limit groove 13 is opened on the surface of the fixed frame 12 and passes through the fixed frame 12, the side panel 14 is fixedly connected to the top of the operating table body 11, the motor 15 is fixedly connected to the outside of the side panel 14 and the output end of the motor 15 passes through the side panel 14, and the conveyor belt 16 is rotatably connected to the outside of the side panel 14 and one end is fixedly connected to the output end of the motor 15.

[0025] Therefore, the operator places the cardboard on the conveyor belt 16 and then turns on the motor 15 to rotate. The motor 15 drives the conveyor belt 16 to move, thereby driving the cardboard to move. After moving to the appropriate position, the cardboard is aligned and inspected by the limiting mechanism 3 and the detection mechanism 2. Qualified cardboard is transported to one end by the conveyor belt 16 for collection, and unqualified cardboard is reversed by the motor 15 and transported to the other end of the conveyor belt for collection and screening.

[0026] like Figure 3-4 As shown, in a preferred embodiment, the detection mechanism 2 includes an electric push rod 21, a sliding block 22, a mounting frame 23, a second sliding limit groove 24, a sliding plate 25, a third sliding limit groove 26, a sliding rod 27, an infrared rangefinder 28 and a handle 29, wherein the electric push rod 21 is fixedly arranged inside the first sliding limit groove 13, the sliding block 22 is fixedly connected to the top of the electric push rod 21 and is slidingly connected to the fixing frame 12 through the first sliding groove, the mounting frame 23 is fixedly connected to the outside of the sliding block 22, the sliding plate 25 is slidingly connected to the mounting frame 23 through the second sliding limit groove 24 and is located inside the mounting frame 23, the third sliding limit groove 26 is opened on the surface of the sliding plate 25 and passes through the sliding plate 25, the sliding rod 27 is slidingly connected to the outside of the sliding plate 25 through the third sliding limit groove 26, and the infrared rangefinder 28 is fixedly connected below the sliding rod 27.

[0027] like Figure 3-4 As shown, in the present disclosure, the limiting mechanism 3 includes a first adjusting screw 31, a vertical limiting plate 32, a sliding rod 33, a second adjusting screw 34, a movable plate 35 and a transverse limiting plate 36, wherein the first adjusting screw 31 is threadedly connected to the bottom of the fixed frame 12 and passes through the fixed frame 12, the vertical limiting plate 32 is rotatably connected to the outside of the first screw, the sliding rod 27 is slidably connected to the fixed frame 12 and passes through the fixed frame 12, the second adjusting screw 34 is threadedly connected to the mounting frame 23 and passes through the mounting frame 23, the movable plate 35 is rotatably connected to the outside of the second adjusting screw 34 and the two ends of the movable plate 35 are slidably connected to the mounting frame 23 through the second sliding limiting groove 24, and the transverse limiting plate 36 is fixedly connected to the bottom of the movable plate 35.

[0028] Therefore, the operator first transports the cardboard to the bottom of the detection mechanism 2 through the conveyor belt 16, and then the operator rotates the first adjusting screws 31 on both sides of the fixed frame 12. The first adjusting screws 31 drive the vertical limit plates 32 to move on the conveyor belt 16. The vertical limit plates 32 move to drive the cardboard on the conveyor belt 16 to move and align the vertical direction of the cardboard.

Then the operator turns on the infrared rangefinder 28, and drives the sliding rod 27, the sliding plate 25 and the infrared rangefinder 28 to move by pushing the handle 29 and detects various parts of the cardboard.
