Description

Technical Field

[0001] This application relates to the field of cardboard box production technology, and more specifically, to an explosion-proof humidification device for a corrugated cardboard box production line. Background Technology

[0002] In the production process of multi-layer corrugated paper, existing technologies often have some shortcomings. These are mainly reflected in the fact that, due to the high cost of paper materials, the rigidity of the cardboard, and the difficulty of water-based die-cutting and slotting, the linerboard at the slotted edge is prone to bursting during box gluing.

[0003] Based on the aforementioned angles where cracking is likely to occur, it is generally necessary to use a humidifier to moisten the pressure points to reduce the risk of cracking.

[0004] Existing humidification devices spray water onto the middle layer of corrugated paper through steam nozzles, and then the water evaporates and diffuses onto the inner and outer linerboards. This humidification method is not ideal and ignores the need for humidification of the easily cracked outer linerboard. In addition, existing devices are complex in structure, inconvenient to operate, and have high maintenance costs, making it difficult to meet the needs of actual production. Utility Model Content

[0005] The purpose of this application is to provide an explosion-proof humidification device for a corrugated cardboard box production line. This device can ensure uniform humidification of the cardboard box surface, maintain stable and continuous humidification operation, effectively prevent the face paper from bursting and breaking during the watermarking process, and can adjust the working position of the humidification components to meet the humidification needs of different models and sizes of cardboard boxes.

[0006] To achieve the above objectives, this utility model provides an explosion-proof humidification device for a corrugated cardboard box production line, installed on the conveyor belt of a cardboard box watermarking machine. The device includes: a frame; a water tank at the top of the frame; a flexible hose connected to the water tank; a slide rail on the frame; a water storage box on the slide rail that can be slidably adjusted in position; the flexible hose connected to the water storage box; a water supply pipe connected to the water storage box; and a rotatable printing water roller at the bottom of the water supply pipe.

[0007] In an optional embodiment, the water storage box is provided with a transverse through groove, the through groove is clearance-fitted with the slide rail, and the slide rail passes through the through groove.

[0008] In an optional embodiment, the water storage box includes a water storage cavity with a U-shaped vertical cross section, and a sealing plate is connected to the recessed part. The sealing plate and the recessed part constitute the through groove of the water storage box.

[0009] In an optional embodiment, the sealing plate has a through hole in the thickness direction, and a nut is welded to the through hole. The nut is located on the side wall of the sealing plate away from the through groove, and a fixing screw is connected to the nut. The fixing screw can pass through the through hole and abut against the slide rail.

[0010] In an optional embodiment, the water supply pipeline includes a water supply steel pipe, the lumen of which communicates with the water storage chamber, and the water supply steel pipe is provided with a water supply valve for controlling the on / off state.

[0011] In an optional embodiment, a bracket is connected to the bottom of the water storage box, and a through shaft is installed at the bottom of the bracket. The printing water roller is rotatably installed at the bottom of the bracket through the through shaft, and the roller surface of the printing water roller is in clearance fit with the conveyor belt.

[0012] In an optional embodiment, the bracket includes two connecting plates arranged opposite each other, the connecting plates being disposed on both sides of the water supply pipe, the two ends of the through shaft being respectively clamped onto the grooves at the bottom of the connecting plates, and the connecting plates being provided with pipe clamps for fixing the water supply pipe.

[0013] In an optional embodiment, the printing water roller includes a roller core and a high-density sponge lining the outside of the roller core, and a bearing is provided between the roller core and the through shaft.

[0014] In an optional embodiment, the bottom opening of the water supply pipe is located at the center of the top of the printing water roller, and the inner diameter of the bottom opening is not greater than 1 / 4 of the outer diameter of the printing water roller. At least one gap is provided between the top of the printing water roller and the bottom opening.

[0015] In an optional embodiment, the bottom opening of the water supply pipe is detachably bound with a cotton cloth tube, and in the soaked state, the bottom of the cotton cloth tube can overlap and contact the high-density sponge.

[0016] By installing an explosion-proof humidification device on the conveyor belt of a carton watermarking machine, the specific pressure lines of the carton can be humidified during the carton conveying process, realizing the integration of conveying and humidification functions and simplifying the manufacturing process.

[0017] The water tank installed on the frame can be used to store water and conveniently output the water required for humidification. By connecting the hose to the water tank and installing a slide rail on the frame, combined with the water storage box that can be slidably adjusted on the slide rail and the connection between the hose and the water storage box, the position of the humidification device on the frame can be adjusted so that the humidification device is aligned with the carton pressing line on the conveyor belt.

[0018] With an adjustable humidifier, the humidification needs of different cartons at specific crease locations can be met.

[0019] The water tank serves as the overall water storage unit, while the water storage box primarily functions to humidify and supply water to specific areas along the printing lines. By connecting a water supply pipe to the water storage box and installing a rotatable printing water roller at the bottom of the pipe, humidifying water can be guided to the printing water roller. Through the frictional rolling of the printing water roller relative to the conveyor belt and the cardboard boxes, the water can be evenly applied to the printing lines of the cardboard boxes, resulting in uniform and stable humidification of the cardboard surface. This achieves continuous humidification during transport, further improving the humidification effect and effectively preventing the surface paper from tearing and breaking during the watermarking process.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0038] The explosion-proof humidification device for corrugated cardboard box production line in this application is mainly used to humidify cardboard boxes during the conveyor belt process. By setting up the necessary water supply structure and the water outlet structure that can be adjusted on the frame, the application range is broadened to meet the humidification needs of cardboard boxes of different models and sizes while meeting the basic humidification function and ensuring the humidification effect.

[0039] Combination Figure 1 and combined Figure 2The explosion-proof humidification device for corrugated cardboard box production line of this utility model is installed on the conveyor belt 7 of the cardboard box watermarking machine. It includes: a frame 1, a water tank 11 is provided on the top of the frame 1, a hose 12 is connected to the water tank 11, a slide rail 13 is provided on the frame 1, a water storage box 2 that can slide and adjust its position is provided on the slide rail 13, the hose 12 is connected to the water storage box 2, the water storage box 2 is connected to the water supply pipe 3, and a rotatable printing water roller 4 is provided at the bottom of the water supply pipe 3.

[0040] By cooperating with the printing water roller 4 and the conveyor belt 7, the carton 8 on the conveyor belt 7 can be squeezed and fitted. When the carton 8 on the conveyor belt 7 reaches the printing water roller 4, the printing water roller 4 at a fixed height squeezes and rubs the carton 8 relative to it. Then, under the action of friction, the printing water roller 4 rotates. While rotating, the humidifying water on it is squeezed and coated onto the pressure line of the carton 8.

[0041] The water tank 11 installed on the frame 1 can be used to store water and conveniently output the water required for humidification. The frame 1 can be the frame 1 of the conveying device. The water tank 11 is fixedly installed on the upper part of the frame 1. The humidifying water is discharged by connecting the hose 12 to the water tank 11.

[0042] Based on the ability of this application to humidify specific crease areas of the carton 8 on the conveyor belt 7, it is necessary to set up a water storage box 2 on the basis of setting up a basic water storage tank 11. By adjusting the position of the water storage box 2 on the frame 1, the position of the humidification device, especially the printing water roller 4, can be changed.

[0043] The slide rail 13 installed on the frame 1 allows the water storage box 2, which is used to transfer humidifying water, to slide and adjust its position. By connecting the two ends of the hose 12 to the water tank 11 and the water storage box 2 respectively, it is convenient to adjust the position of the water storage box 2 on the frame 1 in the form of the hose 12.

[0044] Water storage box 2 is connected to water supply pipe 3. Printing water roller 4 can rotate freely under the action of relative squeezing friction. When adjusting the position, water storage box 2, water supply pipe 3 and printing water roller 4 are connected as a whole and slide on slide rail 13 to adjust the position so that printing water roller 4 is opposite to the pressure line position of carton 8 on conveyor belt 7.

[0045] By adjusting the position of the connection, the humidification requirements of different cartons 8 at specific crease locations can be met. By adjusting the relative relationship of the water storage box 2, water supply pipe 3 and printing water roller 4, the final printing water roller 4 can be aligned with the crease position of the carton 8, thus meeting the humidification requirements of cartons 8 of different sizes and models.

[0046] The water supply pipe 3 can spray humidifying water onto the printing water roller 4 and guide the humidifying water onto the printing water roller 4. Through the squeezing and friction rolling of the printing water roller 4 relative to the carton 8 on the conveyor belt 7, the water is evenly applied to the pressure lines of the carton 8, so that the humidification effect on the surface of the carton 8 is uniform and stable, realizing a continuous humidification state during conveying, further improving the humidification effect, and effectively preventing the outer cracking and damage of the face paper during the water printing process.

[0047] In one specific embodiment, to facilitate adjustment of the positions of the water storage tank 11, the water supply pipe 3, and the printing water roller 4, the water storage box 2 is constructed with a transversely penetrating groove 21. The groove 21 is clearance-fitted with the slide rail 13, and the slide rail 13 passes through the groove 21. The sliding fit between the groove 21 and the slide rail 13 allows for the repositioning of the humidification component on the frame 1.

[0048] In this embodiment, the water storage box 2 includes a water storage cavity 22 with a U-shaped vertical cross section. Humidifying water is drawn from the water tank 11 through the hose 12 and enters the water storage cavity 22. A sealing plate 23 is connected to the recessed part. The sealing plate 23 and the recessed part form the through groove 21 of the water storage box 2, thereby providing spatial and functional isolation between the water storage cavity 22 inside the water storage box 2 and the through groove 21 outside.

[0049] To fix the water storage box 2 on the slide rail 13 after its position is adjusted, a through hole 24 is provided in the thickness direction of the sealing plate 23. A nut 25 is welded to the through hole 24. The nut 25 is located on the side wall of the sealing plate 23 away from the through groove 21. A fixing screw 26 is connected to the nut 25. The fixing screw 26 can pass through the through hole 24 and abut against the slide rail 13. After the position of the water storage box 2 is adjusted, the end of the fixing screw 26, which is in the form of a bolt, is pre-tightened against the slide rail 13 by rotating the fixing screw 26, thereby fixing the position of the water storage box 2 on the slide rail 13.

[0050] In order to ensure the effectiveness and reliability of the humidification water output, the water supply pipe 3 connected to the water storage box 2 includes a water supply steel pipe. The lumen of the water supply steel pipe is connected to the water storage chamber 22, so that the water supply pipe 3 can move synchronously with the water storage box 2. In order to control the on / off of the humidification water output and the supply amount, a water supply valve 31 for controlling the on / off is provided on the water supply steel pipe.

[0051] In another specific embodiment, from the installation angle of the printing water roller 4, the bottom of the water storage box 2 is connected to a bracket 5, and a through shaft 41 is installed at the bottom of the bracket 5. The printing water roller 4 is rotatably installed at the bottom of the bracket 5 through the through shaft 41.

[0052] Specifically, through the above connection method, the printing water roller 4 can be fixedly installed on the bracket 5. At the same time, in order to form a squeezing and frictional rolling between the printing water roller 4 and the carton 8 on the conveyor belt 7, the roller surface of the printing water roller 4 and the conveyor belt 7 are fitted with a gap. Preferably, the gap of the gap needs to meet the requirement of being less than the thickness of the carton 8, so that when the carton 8 reaches the part of the printing water roller 4, the roller surface of the printing water roller 4 forms a squeezing relationship with the carton 8.

[0053] The bracket 5 includes two connecting plates 51 arranged opposite to each other. The connecting plates 51 are arranged on both sides of the water supply pipe 3. The two ends of the through shaft 41 are respectively clamped on the grooves at the bottom of the connecting plates 51, so that the bottom of the water supply pipe 3 is aligned with the vertical position of the printing water roller 4 on the through shaft 41, and the humidifying water in the water supply pipe 3 can be guided to the printing water roller 4.

[0054] The connecting plate 51 is provided with a pipe clamp 52 for fixing the water supply pipe 3, which can ensure the fixation of the water supply pipe 3 and ensure stability.

[0055] It should be noted that, in addition to the form of a steel water pipe, the water pipe 3 can also be set as a rigid rubber pipe, which can meet the requirement that the humidified water is discharged and moved synchronously with the water storage box 2 without being arbitrarily shaken.

[0056] In this embodiment, the printing water roller 4 includes a roller core 42 and a high-density sponge 43 attached to the outside of the roller core 42. A bearing is provided between the roller core 42 and the through shaft 41. The through shaft 41 is fixed on the bracket 5. The bearing enables the printing water roller 4 to rotate by squeezing and friction.

[0057] Combined with the high-density sponge 43 attached to the outside of the roller core 42, the water adsorbed in the high-density sponge 43 can be released when the roller is squeezed and rotated. At the same time, the released humidifying water is evenly coated on the pressure line of the carton 8 during rotation, thereby achieving uniform humidification in a dynamic and continuous state.

[0058] The bottom port 32 of the water supply pipe 3 is located at the center of the top of the printing water roller 4, which can deliver the humidifying water in the water supply pipe 3 to the high-density sponge 43 of the printing water roller 4 in the form of spraying.

[0059] See Figures 3-4 To prevent the humidifying water from splashing randomly, the inner diameter of the bottom opening 32 is no greater than 1 / 4 of the outer diameter of the printing water roller 4. Furthermore, at least a gap is provided between the top of the printing water roller 4 and the bottom opening 32, which can ensure the effective output of the humidifying water without affecting the rotation of the printing water roller 4.

[0060] Meanwhile, in order to further prevent the humidifying water from splashing, a cotton cloth tube 6 is detachably tied to the bottom opening 32 of the water supply pipe 3. When the water is soaked, the bottom of the cotton cloth tube 6 can overlap and contact the high-density sponge 43, and the humidifying water can be discharged in the form of siphon, minimizing the risk of humidifying water splashing.

[0061] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
