[0002] Corrugated paper is a plate-shaped object formed by bonding a facing paper and a corrugated paper in a waveform processed by a corrugating roll. In the production and processing of corrugated cardboard, when the corrugated cardboard enters the subsequent stacking from the paper outlet of the counting machine, due to the very high requirements for the surface paper of the corrugated cardboard in corrugated cardboard printing, no defects or indentations are allowed. Therefore, in order to protect the surface paper of the corrugated cardboard from being scratched when entering the stacking, it is necessary to manually turn the corrugated cardboard coming out of the counting machine. At present, the existing corrugated cardboard turning mainly includes manual turning and turning machine turning. The efficiency of manual turning is low and the working intensity is high. When the existing corrugated paper turning machine turns the stacked corrugated cardboard, during the clamping and turning process, the middle corrugated cardboard is easily thrown out due to insufficient friction between the cardboard and the cardboard or too fast turning speed. Therefore, in view of the above problems, a cardboard turning device capable of preventing cardboard from being thrown out is proposed. Content of the Utility Model

One end of the sliding frame 4 is fixedly connected to a positioning frame 5. The outside of the positioning frame 5 is fixedly connected to an electric push rod 6. The inside of the positioning frame 5 is slidably connected to a fixed frame 7. The inside of the fixed frame 7 is fixedly connected to a conveyor 8. The bottom end on the left side of the support 1 is fixedly connected to a controller 16.

[0023] Example 2

[0024] As Figures 4-5As shown in the figure, to solve the problem of inconvenience in preventing the cardboard from being pinched, one end of the electric push rod 6 is fixedly connected with a pressing block 9 which is slidably connected to the fixing frame 7. One end of the pressing block 9 is fixedly connected with a control switch 10. One outer end of the pressing block 9 is provided with a first spring 11, and the first spring 11 is fixedly connected to the pressing block 9 and the fixing frame 7. By controlling the electric push rod 6 to extend, the pressing block 9 compresses the first spring 11, further triggering the control switch 10, thereby automatically controlling the electric push rod 6 to stop, and preventing the cardboard from being pinched.

[0025] Embodiment 3

[0026] As Figure 3 shown in the figure, to solve the problem of inconvenience in adjusting the other sliding frame 4 according to the adjustment degree of one side sliding frame 4, a scale 12 is provided on one side of the top end of the sliding frame 4, and the scale 12 is fixedly connected to the sliding frame 4. By observing the scale 12 at the top end of the sliding frame 4 during the process of adjusting the sliding frame 4, it is convenient to adjust the other sliding frame 4 according to the adjustment degree of one side sliding frame 4.

[0027] Embodiment 4

[0028] As Figure 3 shown in the figure, to solve the problem of inconvenience in quickly flipping the cardboard, tooth rings 13 are fixedly connected to both the left and right ends of the outer side of the rotating sleeve 2. A motor 14 is fixedly connected to the bottom end on the right side of the bracket 1. A gear 15 is fixedly connected to the outer side of the main shaft of the motor 14, and the gear 15 is meshed with the tooth ring 13. By controlling the motor 14 to drive the gear 15 to mesh with the tooth ring 13, the rotating sleeve 2 is further driven to rotate, facilitating the quick flipping of the cardboard in the rotating sleeve 2.

[0029] Embodiment 5

[0030] As Figures 1-3 shown in the figure, to solve the problem of inconvenience in ensuring the stability of the cardboard before and after flipping, a connecting rod 17 is slidably connected to the top end of the bracket 1. One end of the connecting rod 17 is fixedly connected with a sliding plate 18 which is slidably connected to the bracket 1. A second spring 19 is provided on the outer side of one end of the connecting rod 17, and the second spring 19 is fixedly connected to the sliding plate 18 and the bracket 1. The other end of the connecting rod 17 is fixedly connected with a pressing rod 20. A gasket 21 made of rubber is fixedly connected to the bottom end of the pressing rod 20, and the gasket 21 is in contact with the rotating sleeve 2. By making the gasket 21 made of rubber at the bottom end of the pressing rod 20 be in close contact with the rotating sleeve 2 under the elastic force of the second spring 19 on the sliding plate 18, and in combination with the characteristic that the friction between the gasket 21 made of rubber and the rotating sleeve 2 is relatively large, the stability of the cardboard before and after flipping is ensured.

[0031] In this embodiment, when the cardboard is flipped by the device, first rotate the threaded shaft 3 which is helically connected to the sliding frame 4 according to the width of the cardboard, so as to adjust the distance between the conveyors 8 in the front and rear positioning frames 5 according to the width of the cardboard. After adjustment, the device can be used. When the cardboard is conveyed by an external conveying mechanism to the outside of the conveyor 8 in the positioning frame 5 during the use of the device, control the electric push rod 6 to extend through the controller 16. When the conveyors 8 on the upper and lower sides are both in contact with the cardboard, the control switch 10 is triggered after the pressing block 9 compresses the first spring 11. After the cardboard is clamped, the electric push rod 6 will automatically stop extending. Then drive the gear 15 to engage with the toothed ring 13 by controlling the motor 14, and further control the rotating sleeve 2 to drive the cardboard to rotate 180 degrees, which can quickly flip cardboard of different sizes while preventing the cardboard from being thrown out. Because at this time, the gasket 21 made of rubber at the bottom end of the pressure rod 20 contacts the rotating sleeve 2 under the elastic force of the second spring 19 on the sliding plate 18, so when the rotating sleeve 2 rotates 180 degrees and the motor 14 stops, in cooperation with the characteristic that the friction between the rubber gasket 21 and the rotating sleeve 2 is relatively large, the cardboard inside the rotating sleeve 2 will be stable at the corresponding position after rotation. Finally, after controlling the electric push rod 6 to contract and reset, the flipped cardboard can be conveyed out.
