Description

Technical Field

[0001] The utility model relates to the technical field of corrugated paperboard processing, in particular to a humidifying device for explosion-proof lines of corrugated paper boxes. Background Art

[0002] Corrugated paper boxes are the most widely used packaging products, and their usage has always been the highest among all packaging products. This includes calcium plastic corrugated paper boxes. For more than half a century, corrugated paper boxes have gradually replaced wooden boxes and other transport packaging containers with their superior performance and good processing performance, becoming the main force of transport packaging. In addition to protecting goods and facilitating storage and transportation, they also play a role in beautifying and promoting goods.

[0003] Cardboard and cartons may have poor forming and bursting lines at the pressing lines and forming parts due to reasons such as the short wood pulp fibers of the base paper, the production process, and the low moisture content of the base paper, which will lead to a lot of waste and increase costs. The effective solution is to increase the moisture content of the cardboard at the pressing lines and forming parts through some method or device.

[0004] Announcement No. CN219690188U proposes a device for preventing corrugated cardboard and carton from bursting. The device detects the water flow rate passing through the water outlet pipe through a water flow sensor, and controls the water flow passing through the water outlet pipe by a controller according to the water flow rate, thereby achieving accurate control of the atomizing nozzle for water spraying and humidification to avoid damaging the cardboard strength of the corrugated cardboard or carton; however, the position of the device when placing the corrugated cardboard on the conveying equipment at the beginning is not unique, and the position of the device when it is conveyed to the humidifying equipment is not unique. Subsequently, the position of the pointer needs to be adjusted according to the different placement positions of the cardboard each time before processing can be carried out. The processing efficiency is general. In addition, the effect of humidifying the indentation after atomization with normal temperature water needs to be further improved. Utility Model Content

[0008] This device can ensure that the placement orientation of the corrugated cardboard on the conveyor belt is unique, and then the position when it arrives at the humidification equipment is unique. Then the humidification equipment and the pressing assembly move along a fixed trajectory to achieve the pressing and humidification process of the corrugated cardboard.

The utility model is further described in combination with the drawings and embodiments:

[0021] like Figure 1 and Figure 2 As shown, a corrugated cardboard explosion-proof line humidifying device includes a conveyor belt 1 and a wire pressing assembly 34. The wire pressing assembly 34 has been disclosed in a corrugated cardboard and carton explosion-proof device proposed in announcement No. CN219690188U, which belongs to the prior art and does not require improvement. A mounting frame 12 and multiple groups of right-angle limit blocks 11 for limiting the position of the corrugated cardboard are provided on the conveyor belt 1, one group includes two and the two right-angle limit blocks 11 are diagonally arranged, a dual-axis drive assembly and a steam generator 2 are provided on the mounting frame 12, and the steam generator 2 belongs to the prior art and does not require improvement. A conveying pipe 32 with an open end is provided on the dual-axis drive assembly, and the conveying pipe 32 is connected to the output end of the steam generator 2 through a hose 33, and the open end of the conveying pipe 32 is connected to a nozzle 35. Specifically, the nozzle 35 adopts a dynamic pressure nozzle, and the dynamic pressure nozzle belongs to the prior art and does not require improvement. A wire pressing assembly 34 is provided on the conveying pipe 32.

[0022] Specifically, the dual-axis driving assembly is a cross slide 31 , and the mounting frame 12 is provided with the cross slide 31 . The cross slide 31 is driven by a screw structure and is connected to a conveying pipe 32 . The screw structure is shown in the figure without a number.

[0023] In a further refinement of the embodiment of the present invention, a through hole is provided on the side wall of the mounting frame 12 to allow the hose 33 to move, and the through hole is not shown in the figure.

[0024] It should be noted that the conveyor belt 1, the wire pressing assembly 34, the cross slide 31 and the steam generator 2 are all electrically connected to the controller, which is not shown in the figure.

[0025] The workflow of this utility model:

[0026] First, place a piece of corrugated cardboard between a group of linear limit blocks. After placement, the two diagonals of the corrugated cardboard are in contact with two right-angle limit blocks 11 respectively. At this time, the placement position of the corrugated cardboard on the conveyor belt 1 can be limited, and then the conveyor belt 1 is transported forward at a uniform speed, and then the placement of the corrugated cardboard in several groups of right-angle limit blocks 11 can be realized in turn. As the conveying proceeds, when the frontmost corrugated cardboard moves to the bottom of the mounting frame 12, the controller immediately controls the conveyor belt 1 to stop working. After the conveyor belt 1 stops, the controller immediately controls the cross slide 31, the wire pressing assembly 34 and the steam generator 2 to work. The cross slide 31 works and then drives the wire pressing assembly 34 and the humidifying assembly to follow the fixed trajectory pre-set in the controller. The pressing component works and then approaches the indentation of the corrugated cardboard to perform the pressing process. The humidifying component works and can humidify the indentation of the corrugated cardboard through the nozzle 35 after the pressing is completed. As the steam generator 2 works, the hot air moves along the hose 33 to the conveying pipe 32 and then sprays out through the nozzle 35 to complete the humidification process. It should be noted that the distance between the nozzle 35 and the corrugated cardboard is very small, and the output steam can be completely sprayed to the indentation of the corrugated cardboard for humidification. After the humidification of a piece of corrugated cardboard is completed, the controller immediately controls the conveyor belt 1 to resume work, and then repeats the above process to sequentially humidify several corrugated cardboards in the assembly line to prevent the subsequent corrugated cardboards from bursting during the process of folding into cartons.

[0027] Compared with the prior art, the device can ensure that the placement orientation of the corrugated cardboard on the conveyor belt 1 is unique, and thus the position when it arrives at the humidification equipment later is unique. Then the humidification equipment and the pressing assembly move along a fixed trajectory to achieve the pressing and humidification process of the corrugated cardboard. At the same time, the steam has a certain amount of heat, so that the explosion-proof line effect of the corrugated cardboard after humidification is better.

[0028] In some embodiments, Figure 1 and Figure 2 As shown, an infrared transmitter 41 is arranged on one of the right-angle limit blocks 11 in each group of right-angle limit blocks 11, a through hole 121 with a main body in a rectangular shape and a mounting rod 13 are arranged on the mounting rod 13, and an infrared receiver 42 is arranged on the mounting rod 13. The infrared receiver 42 is arranged opposite to the through hole 121 and cooperates with the infrared transmitter 41 and is electrically connected; this embodiment can ensure that each corrugated cardboard is accurately stopped at a designated position below the mounting frame 12 through the cooperation of the infrared transmitter 41 and the infrared receiver 42, and then the movement trajectory of the subsequent nozzle 35 and the crimping assembly accurately coincides with the indentation of the corrugated cardboard, thereby reducing the error.

[0029] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions in the specification are only to illustrate the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the protection required by the utility model.
