Description

Technical Field

[0001] The utility model relates to the technical field of corrugated cardboard printing, in particular to a corrugated cardboard printing and turning device. Background Art

[0002] Corrugated cardboard is a board material consisting of a corrugated core layer and a covering layer formed between two or more layers of cardboard. It is mostly used in the packaging industry. When actually producing corrugated cardboard, a printing press is required to complete the printing work on the surface of the corrugated cardboard. This process requires a turning device to turn the corrugated cardboard over for printing. In actual use, it has the advantages of simple operation, stable structure and good use effect.

[0003] The prior art discloses a corrugated cardboard printing and turning device with a publication number of CN216037120U, which includes a fixed frame, a fixed shaft, a sleeve, a bearing, a turning frame, a worm gear, a bracket, a motor, a worm, a flow channel, a first conveyor, an electric rubber roller, a guide frame and a second conveyor. All electrical appliances in the device are external power supplies. When the device is used, the corrugated cardboard is placed on the second conveyor at equal intervals. At this time, the printed corrugated cardboard will be continuously and uniformly conveyed to the right. When the corrugated cardboard contacts the electric rubber roller, the corrugated cardboard will quickly pass from the left guide frame to the right. It is transported to the right to the turning rack, because the motor will continuously drive the worm and the worm wheel to engage at a uniform speed, thereby continuously driving the turning rack outside the sleeve to rotate at a uniform speed through the fixed shaft. At this time, the turning rack that turns to the left will just continuously hold up the corrugated cardboard that slides down, and then drive the corrugated cardboard to rotate clockwise. When the next turning rack turns to the left, it just holds up another adjacent corrugated cardboard that slides down. When the corrugated cardboard is turned over and turned to the right, the turned corrugated cardboard will be continuously transported to the right under the transportation of the conveyor, and finally the corrugated cardboard can be collected centrally.

The corrugated cardboard that has not left the turning frame cannot be turned over, which reduces the practicality of the utility model.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

Before this, the operator first moves the multiple groups of push plates on the same vertical plane by hand. When the multiple groups of push plates on the same vertical plane are moved to the appropriate position, the operator rotates the multiple groups of fastening bolts clockwise by hand. When the multiple groups of fastening bolts contact the rotating column, the use position of the multiple groups of push plates on the same vertical plane is fixed, and the adjustment of the remaining groups of push plates is known from the same operation. At this time, the corrugated cardboard moved into the slot can be limited by the two groups of push plates on the same side to avoid the corrugated cardboard from shaking back and forth during the flipping process. The rotating column, slot and push plate can avoid shaking back and forth during the flipping process of the corrugated cardboard, which provides a guarantee for the flipping of corrugated cardboards of various widths in the corrugated cardboard printing flipping device.

The electric telescopic rod 5 is extended, and the use height of the rubber roller 7 can be adjusted through the groove plate 6. The first belt conveyor 2 can move multiple corrugated cardboards. The output end of the servo motor 15 can drive the main gear 16, a group of first pulleys 19 and a group of second pulleys 20 to rotate. Since the main gear 16 and the driven gear 13 are meshed with each other, the rotating main gear 16 can drive the driven gear 13 to rotate, and the rotating driven gear 13 can be installed The shaft 10 drives the rotating column 11 to rotate, and the driving motor can drive the rubber roller 7 to rotate. When the rotating rubber roller 7 contacts a corrugated cardboard, the corrugated cardboard can be quickly moved and moved into a group of slots 12. The rotating column 11 can drive the corrugated cardboard to rotate. Finally, the corrugated cardboard will fall onto the second belt conveyor 3 due to gravity. The second belt conveyor 3 works to transport this group of corrugated cardboard. The corrugated cardboard that falls on the second belt conveyor 3 is turned over. At the same time, the output end of the servo motor 15 rotates the multiple transmission shafts 18 through multiple groups of first pulleys 19, multiple groups of second pulleys 20, multiple groups of first transmission belts 21 and multiple groups of second transmission belts 22. The rotating transmission shafts 18 can The plurality of fan blades 9 are driven to rotate respectively, and air can contact the plurality of corrugated cardboards through the ventilation holes 8, and the flowing air can dry the ink on the surface of the plurality of corrugated cardboards. The plurality of filter screens 17 can prevent impurities from passing through the plurality of ventilation holes 8. The ventilation holes 8 and the fan blades 9 are provided with a drying structure, and the ink on the surface of the corrugated cardboard can be dried before turning over, thereby improving the practicality of the corrugated cardboard printing turning device. At the same time, according to the above operation, the plurality of corrugated cardboards can be moved into the interior of the plurality of slots 12 respectively, and the rotating rotating column 11 can drive the plurality of corrugated cardboards to turn over, so that they finally fall on the second belt conveyor 3 in sequence. Prior to this, the operator first moves the plurality of slots 12 on the same vertical plane by hand. When the multiple push plates 23 on the same vertical plane are moved to the appropriate position, the operator rotates the multiple fastening bolts 25 clockwise by hand. When the multiple fastening bolts 25 contact the rotating column 11, the use position of the multiple push plates 23 on the same vertical plane is fixed, and the adjustment of the remaining push plates 23 is the same.
