Description

Technical Field

[0001] This utility model relates to the field of corrugated paper production technology, and in particular to a corrugated cardboard spray humidification device. Background Technology

[0002] In the production of corrugated cardboard, the moisture content not only significantly affects the cardboard's hardness and flatness but also impacts subsequent printing, laminating, and die-cutting processes. Therefore, controlling the moisture content of corrugated cardboard is extremely important and technically demanding. Existing spray humidification devices are rudimentary; some water mist drifts into the workshop during spraying, causing unstable water coverage on the corrugated cardboard surface. Furthermore, the water mist creates a high-humidity environment for both production equipment and workers, severely impacting worker comfort and the stability and lifespan of equipment.

[0003] Publication number CN215856950U discloses a spray humidification device for corrugated cardboard production, including a humidification box with symmetrically opened channels on its side wall. A conveyor belt passes through the channels. The humidification box also has air vents communicating with the channels, facing the upper surface of the conveyor belt. The air vents are connected to a first fan located on the side wall of the humidification box. A compressor pump is located above the humidification box and connected to a spray terminal in the humidification box facing the upper surface of the conveyor belt. A liquid storage tank is located below the humidification box and connected to its bottom. A labyrinthine air guide plate is also provided between the bottom of the humidification box and the conveyor belt, forming a dehumidification channel. A second fan is also located on the side wall of the humidification box and connected to the end of the dehumidification channel. This structure ensures precise humidification of the corrugated cardboard while effectively improving the workshop environment.

[0004] While the above solutions ensure precise humidification of corrugated cardboard and effectively improve the workshop environment, the fact that only one side of the corrugated cardboard is humidified by spray affects the overall processing effect. Moreover, the limited spray area requires water mist dehumidification. Therefore, we propose a corrugated cardboard spray humidification device. Utility Model Content

[0005] The main purpose of this utility model is to provide a corrugated cardboard spray humidification device. By setting up a conveying unit and a spraying unit, it solves the problem that only one side of the corrugated cardboard is sprayed with humidification, which affects the overall processing effect. Moreover, the limited spray area also requires water mist dehumidification.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: a corrugated cardboard spray humidification device, including a processing box and a water tank fixedly installed at the bottom of the processing box via a collection hopper, and further including: a conveying unit and a spraying unit installed on the processing box, wherein a vertical strip groove is respectively opened on the opposite two sides of the processing box;

[0007] The conveying unit includes a rectangular frame plate, a transverse screw, a support plate, a rotating shaft, a vertical roller, a rotating motor, and a transverse roller. The rectangular frame plate is fixedly installed on one side surface of the processing box and located outside the vertical strip groove. Two strip mounting slots are symmetrically opened on the side of the rectangular frame plate. The transverse screw is movably installed on one of the strip mounting slots. There are four support plates in total, divided into two groups. The two groups of support plates are located on the two strip mounting slots respectively. One group of support plates is respectively matched with the two symmetrically arranged positive and negative threads on the transverse screw. A rotating shaft is embedded in each pair of support plates located on the same vertical center horizontal plane. The two vertical rollers are respectively fixedly sleeved on the outer circumference of the middle end of the two rotating shafts. The rotating motor is installed on the top surface of one of the support plates and its output end is connected to the top end of one of the rotating shafts. Several transverse rollers are equidistantly installed on the inner wall of the side side of the bottom of the processing box.

[0008] The spraying unit includes a delivery pump, a water pipe, a vertical spray plate, a support frame, and a filter plate. Two delivery pumps are symmetrically placed inside the water tank. Two water pipes are installed at the output ends of the two delivery pumps, and the water pipes pass through the inner side wall of the water tank and the inner side wall of the treatment tank in sequence. Two vertical spray plates are fixedly installed on the end faces of the two water pipes extending into the treatment tank and are arranged opposite each other. The support frame is fixedly installed on the inner wall of the middle section of the water tank. A positioning groove is opened on one side surface of the water tank. The filter plate extends movably into the water tank through the positioning groove and is located above the support frame.

[0009] Preferably, the conveying unit further includes a guide rod, which is fixedly mounted on another strip mounting groove and movably passes through another set of support plates.

[0010] Preferably, a turntable is fixedly installed on the end face of the transverse lead screw located outside the rectangular frame plate.

[0011] Preferably, the vertical spray plate and the vertical roller are arranged parallel to each other.

[0012] Preferably, a set of mounting blocks is fixedly installed on the opposite outer walls of the processing box.

[0013] Preferably, each mounting block has a support foot installed on its bottom surface.

[0014] Compared with the prior art, the corrugated cardboard spray humidification device of this utility model has the following beneficial effects:

[0015] 1. In this utility model, by setting up a conveying unit, a vertical strip groove is opened on each of the opposite sides of the processing box to accommodate the vertical placement and entry / exit of corrugated cardboard. Before entering the processing box, the vertically placed corrugated cardboard can be placed between two vertical rollers. By holding and rotating the horizontal screw outside the rectangular frame plate, two support plates threaded to the horizontal screw are subjected to force and move relative to each other, which can drive two rotating shafts to adjust the distance. The other two support plates can slide and translate on the guide rod to cooperate with the adjustment of the two rotating shafts and provide auxiliary support. The two vertical rollers are driven by the two rotating shafts to adjust the distance and can clamp the vertically placed corrugated cardboard. The operation of the rotating motor drives one of the rotating shafts to rotate, one of the vertical rollers rotates actively, and the other vertical roller follows the rotation, which can push the corrugated cardboard into the processing box. Several horizontal rollers installed at equal intervals on the inner wall of the bottom side of the processing box can roll to cooperate with the movement of the corrugated cardboard and provide auxiliary support. The equipment can accommodate the vertical placement and conveying of corrugated cardboard, receive spray humidification, and is suitable for a wide range of corrugated cardboard thicknesses.

[0016] 2. In this utility model, by setting up a spray unit, when the vertically placed corrugated cardboard enters and exits the processing box, two symmetrically placed conveying pumps in the water tank can work with two water pipes to input the water in the water tank into two vertically arranged spray plates in opposite directions in the processing box. When the vertically placed corrugated cardboard is conveyed, it can be sprayed and humidified simultaneously on both sides. Excess water will slide directly off the vertically placed corrugated cardboard and be guided into the water tank through the collection hopper. The filter plate, which is placed in the water tank through the positioning channel and located above the support frame plate, can be used to remove debris and allow excess water to fall into the bottom of the water tank for reuse. The equipment fully sprays the corrugated cardboard area and completes the recycling of excess water. Attached Figure Description

The corrugated cardboard is pushed through the interior of the processing box 1. Several horizontal rollers 307, which are equidistantly installed on the inner wall of the bottom side of the processing box 1, roll in coordination with the movement of the corrugated cardboard and provide auxiliary support. When the vertically placed corrugated cardboard enters and exits the processing box 1, two conveying pumps 401, which are symmetrically placed in the water tank 2, work with two water pipes 402 to input water from the water tank 2 into two vertical spray plates 403, which are arranged opposite each other in the processing box 1. The vertically placed corrugated cardboard is simultaneously sprayed and humidified on both sides during the conveying process. Excess water will slide directly off the vertically placed corrugated cardboard and be guided into the water tank 2 through the collection hopper. The filter plate 405, which is placed in the water tank 2 through the positioning groove and located above the support frame plate 404, separates the debris and, together with the excess water, falls into the bottom of the water tank 2 for reuse.
