DETAILED DESCRIPTION

[0016] The utility model is further explained in connection with the drawings below.

[0017] Embodiment: as Figure 1 , Figure 2 , Figure 3 , Figure 4 Indicated, a kind of paperboard flattening device for packaging carton processing, including bottom plate 1, placing plate 2, top plate 3 and pressing plate 4, the bottom plate 1 is transversely arranged, and the lower surface of both sides is longitudinally fixedly provided with support plate 11, and the upper surface of rear end is vertically fixedly provided with connecting plate 12, the front end face lower end of connecting plate 12 is longitudinally provided with guide plate 13 in both sides, and the lower end of guide plate 13 is fixedly connected with the upper surface of bottom plate 1, and the inner side is vertically provided with sliding groove 14, the placing plate 2 is flat with bottom plate 1, and both ends are fixedly provided with sliding block, and are slidably arranged between two guide plates 13 by the cooperation of sliding block and sliding groove 14, and buffer air bag 5 is fixedly arranged between the lower surface of placing plate 2 and the upper surface of bottom plate 1, left side of buffer air bag 5 is connected with air inlet pipe, and one-way inlet valve is connected to air inlet pipe, left side is connected with exhaust pipe, and pressure valve is connected to exhaust pipe;The top plate 3 is located in the upper of placing plate 2, and is vertically fixedly connected with the upper end of connecting plate 12, and recess 31 is arranged in the middle position of top plate 3 lower surface, and elastic member 32 is vertically fixedly arranged at four corners of top plate 3 lower surface, electromagnet 33 is fixedly arranged in recess 31, the pressing plate 4 is located in the lower of top plate 3, and is fixedly connected with the lower end of elastic member 32, and counterweight 41 is fixedly arranged in the middle position of pressing plate 4 upper surface, and iron plate 42 is fixedly arranged above counterweight 41.

[0018] The elastic member 32 is composed of a guide telescopic rod and a spring sleeved outside the guide telescopic rod; the two sides of the connecting plate 12 at the connecting position with the top plate 3 are fixedly provided with reinforced blocks 15 in right triangle structure, and the reinforced blocks 15 can increase the stability of the vertical fixed connection between the connecting plate 12 and the top plate 3; the upper end of the electromagnet 33 is fixedly connected with the groove bottom surface of the groove 31, the lower end protrudes from the groove 31 and is located below the top plate 3 and in contact with the upper surface of the iron plate 42; the front end and the rear end of the two side surfaces of the pressing plate 4 are fixedly provided with infrared detection assemblies 43, and the infrared detection assemblies 43 can detect whether the paperboard is placed in a neat manner.

[0019] In use, first, the power supply circuit of the electromagnet 33 is turned on, and the magnetic attraction of the electromagnet 33 to the iron plate 42 is utilized to limit the positions of the top plate 3, the counterweight block 41 and the pressing plate 4, thereby avoiding the problem that the placement operation of the pressing plate 4 on the paperboard is affected when the paperboard is subsequently stacked and placed; then, the paperboard to be flattened is sequentially stacked and placed on the upper end of the placement plate 2, and in this process, the infrared rays emitted by the infrared detection assembly 43 are utilized to detect whether the paperboard is placed in a neat manner; after the paperboard is stacked and placed, the power supply circuit of the electromagnet 33 is cut off, so that the electromagnet 33 loses the magnetic attraction to the iron plate 42; at this time, the gravity of the counterweight block 41 can drive the pressing plate 4 to move downward, thereby pressing the paperboard stacked and placed between the placement plate 2 and the pressing plate 4, realizing the pressure flattening of the paperboard; and in this process, when the weight of the counterweight block 41 is too large, causing the pressing plate 4 to exert too much pressure on the paperboard, and further causing the buffer air bag 5 to bear too much pressure, the air in the buffer air bag 5 will rush to open the pressure valve externally connected to the exhaust pipe, and perform the exhaust operation; as the buffer air bag 5 exhausts outward, it will shrink; at this time, the sliding connection between the placement plate 2 and the guide plate 13 through the sliding block and the sliding groove 14 can drive the placement plate 2, the stacked and placed paperboard, the pressing plate 4 and the counterweight block 41 to move vertically downward while the buffer air bag 5 shrinks; thus, the downward movement of the pressing plate 4 can drive the elastic member 32 to expand, and the continuous expansion of the elastic member 32 can gradually increase the tension on the pressing plate 4, thereby gradually reducing the pressure exerted by the counterweight block 41 and the pressing plate 4 on the paperboard; as the buffer air bag 5 shrinks to adjust the pressure exerted by the pressing plate 4, when the buffer air bag 5 no longer shrinks and the placement plate 2, the stacked and placed paperboard, the pressing plate 4 and the counterweight block 41 no longer move downward, the utility model is in a balanced state as a whole; at this time, the cooperation between the pressing plate 4 and the placement plate 2 can press and flatten the paperboard stacked and placed therebetween; the utility model adopts this structure, which can avoid the situation that the paperboard is damaged due to too much pressure exerted by the pressing plate 4; in general, the utility model has the advantages of reasonable structure design and good use effect.
