Description

Technical Field

[0001] The invention belongs to the technical field of corrugated paper processing, in particular to a steam device used for processing and bonding corrugated paper. Background Art

[0002] In the corrugated paper production process, the bonding process is extremely critical, as it directly determines the overall strength and durability of the carton; steam, as an efficient heat transfer medium, has gradually entered the field of vision of corrugated paper processing practitioners. Steam can transfer heat to the corrugated paper and glue coating evenly and gently by convection heat transfer. On the one hand, it can accurately control the temperature to avoid local overheating, allowing the glue to fully flow, cross-link and cure within the appropriate temperature range, greatly improving the stability and reliability of the bonding; on the other hand, the latent heat release of steam can provide a stable and continuous energy input for the glue curing reaction, ensuring that the layers of paper are firmly bonded even in the face of complex cardboard structures;

[0003] When bonding corrugated paper, starch adhesive needs to be applied to the flute peaks of the corrugated core paper, and then the bonded corrugated paper will pass between two heating plates. Since the heating plates are filled with steam circulation pipes, high-temperature steam circulates in the pipes. The heat brought by the steam causes the glue to heat up rapidly, and the starch particles quickly absorb water, expand, and gelatinize. The viscosity of the glue is instantly enhanced, allowing the glue to be evenly distributed to achieve a stable bond.

[0004] During the steam bonding process of corrugated paper, steam adopts an S-shaped circulation transmission mode; due to the physical characteristics of the steam circulation system itself, the steam presents an uneven temperature distribution on the flow path. At the beginning of the process, the corrugated paper area through which the steam first flows can first obtain a higher heat input, causing the temperature of this part of the corrugated paper to rise rapidly; and as the steam continues to circulate along the established route, the steam heat received by the subsequent corrugated paper area gradually decays, resulting in uneven temperature. When the temperature is uneven, the viscosity of the adhesive at different temperature positions on the corrugated paper will deviate, which will affect the quality of the corrugated paper.

Since the direction of steam movement is relative to the direction of movement of the corrugated paper, the steam moving from right to left can heat the corrugated paper for a long time. If the heat of the steam decays during the process of moving from right to left, the decayed heat can also preheat the corrugated paper on the left. Since the cyclically rotating driven plate will cyclically drive the steam to move from right to left along the corrugated paper, and the steam movement speed is the same, while ensuring that the corrugated paper moves at a uniform speed, it can ensure that the temperature of the corrugated paper heated by the steam is relatively uniform, thereby avoiding uneven temperature on the corrugated paper.

[0038] 2. The steam device for processing and bonding corrugated paper described in the present invention first introduces steam into the air inlet box and stores it. When the rotating driven plate passes the air inlet position, the piston plate can push the steam into the outer cavity, so that the steam can quickly fill the space between two adjacent driven plates, thereby avoiding the situation where the steam cannot fill the space between two adjacent driven plates, resulting in a difference in the amount of steam between every two adjacent driven plates, which will cause a difference in the heating temperature of the corrugated paperboard passing through, resulting in uneven temperature on the corrugated paper.

[0039] 3. The steam device for processing and bonding corrugated paper described in the present invention can adjust the overall length of the driven plate while keeping the distance between adjacent driven plates unchanged by controlling the distance between the two annular plates, thereby avoiding the situation where the length of the driven plate is much larger than the width of the corrugated paper, thereby causing the steam on both sides of the corrugated paper to be unable to act on the corrugated paper, resulting in a waste of steam.

DETAILED DESCRIPTION

[0053] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0054] Embodiment 1: Figures 1 to 11 As shown, the steam device for corrugated paper processing and bonding described in the present invention is specifically as follows:

[0055] It comprises a frame 1; rollers 11 arranged evenly and rotatably mounted on both sides of the frame 1 and located above the frame 1, and the rollers 11 are used to transport corrugated paper 12;

[0056] Two mirror-image heating plates 2 are installed in the middle of the frame 1. The corrugated paper 12 after gluing will pass between the two heating plates 2, and the heating plates 2 will heat the corrugated paper 12 passing through.

[0057] Both ends of the two heating plates 2 are fixedly connected to the sealing plate 21;

[0058] Support plates 13 are installed on the sealing plates 21 on both sides of the upper heating plate 2; the lower surface of each support plate 13 is fixedly connected to a hydraulic cylinder 14, and the hydraulic cylinder 14 is used to adjust the height of the upper heating plate 2;

[0059] An air outlet pipe 22 is installed on one of the sealing plates 21 of the two heating plates 2;

[0060] The two heating plates 2 are provided with oblong grooves inside; the two oblong grooves are provided with flow guide components, and the flow guide components are used to guide the steam;

[0061] The right sides of the two heating plates 2 are provided with evenly arranged air inlets 23; the right sides of the two heating plates 2 are provided with air intake replenishment mechanisms, and the air intake replenishment mechanisms are used to replenish steam;

[0062] In this embodiment, the flow guide assembly includes an annular bin 3, and the annular bin 3 is an oblong;

[0063] The annular chamber 3 is fixedly connected in the oblong groove, and the oblong groove is divided into an inner cavity 31 and an outer cavity 32, and the air inlet 23 is connected to the outer cavity 32, and the air outlet pipe 22 is connected to the inner cavity 31;

[0064] A rotating belt 33 is rotatably connected to the outer ring surface of the annular bin 3; evenly arranged driven plates 34 are installed on the outer ring surface of the rotating belt 33, and the top of the driven plate 34 is in contact with the surface of the outer cavity 32;

[0065] Both sides of the annular bin 3 are rotatably connected with driving rollers 35, and the driving rollers 35 are in contact with the inner surface of the rotating belt 33; one of the driving rollers 35 is driven by a servo motor 36;

[0066] A cylindrical groove 37 is provided in the inner wall of the heating plate 2 on the left side of the outer cavity 32, and the cylindrical groove 37 is parallel to the driving roller 35; the cylindrical groove 37 is provided with evenly arranged air outlets 38, and the air outlets 38 are connected to the outer cavity 32, and the air outlets 38 are located on the left side of the outer cavity 32, and the air inlet 23 is located on the right side of the outer cavity 32;

[0067] An air pump 39 is installed in the inner cavity 31, and the air pump 39 is installed on the sealing plate 21 without the air outlet pipe 22; a guide tube 391 is installed on the sealing plate 21 without the air outlet pipe 22, and one end of the guide tube 391 is connected to the cylindrical groove 37, and the other end is connected to the air pump 39;

[0068] Specifically, after the corrugated paper 12 is coated with adhesive and bonded, the corrugated paper 12 is transported by the roller 11. The corrugated paper 12 transported by the roller 11 will pass between the two heating plates 2. The distance between the two heating plates 2 is adjusted according to the thickness of the corrugated paper 12 to be heated. During the adjustment, the hydraulic cylinder 14 is controlled to rise or fall, thereby driving the upper heating plate 2 to move, so that the distance between the two heating plates 2 can be adjusted. Before heating the corrugated paper 12, firstly, external steam is introduced into the air intake replenishment mechanism, and the steam entering the air intake replenishment mechanism will The servo motors 36 on the two heating plates 2 are controlled to rotate at the same time. The servo motors 36 drive the rotating belts 33 in the two heating plates 2 to rotate slowly and cyclically. The rotating belt 33 in the lower heating plate 2 rotates counterclockwise along the annular bin 3, and the rotating belt 33 in the upper heating plate 2 rotates clockwise along the annular bin 3. At the same time, the two rotating belts 33 drive the driven plates 34 to rotate cyclically respectively. Since the driven plates 34 are in contact with the surface of the outer cavity 32, the space between the two adjacent driven plates 34 can form a closed space.

[0069] More specifically, when the slowly rotating driven plate 34 passes through the air inlet 23, the air intake replenishing mechanism will pass the internal steam into the space between the two adjacent driven plates 34. When the space between the two adjacent driven plates 34 is filled with steam, the gas in the air intake replenishing mechanism will no longer enter between the two adjacent driven plates 34. Then the driven plate 34 located at the rear will pass through the air inlet 23. Then the air intake replenishing mechanism will pass steam into the space between the two adjacent driven plates 34 at the rear. When the two adjacent driven plates 34 pass through the air outlet 38, they will move with the steam between the adjacent driven plates 34 and move from right to left on the upper and lower sides of the corrugated paper 12. When the corrugated paper 12 passes through the two heating plates 2, the steam moving from right to left will heat the corrugated paper 12. Since the steam fills the space between the two adjacent driven plates 34, Therefore, the entire width direction of the corrugated paper 12 passing through can be heated, thereby avoiding the situation in the prior art that the corrugated paper 12 is heated in an S-shaped circular flow manner, which causes uneven temperature on the corrugated paper 12. Since the direction of steam movement is relative to the direction of movement of the corrugated paper 12, the steam moving from right to left can heat the corrugated paper 12 for a long time. If the heat of the steam decays in the process of moving from right to left, the decayed heat can also preheat the corrugated paper 12 on the left side. Since the cyclically rotating driven plate 34 cyclically drives the steam to move from right to left along the corrugated paper 12, and the steam movement speed is the same, while ensuring that the corrugated paper 12 moves at a uniform speed, it can ensure that the temperature of the corrugated paper 12 heated by the steam is relatively uniform, thereby avoiding uneven temperature on the corrugated paper 12.

[0070] Furthermore, when the driven plate 34 drives the steam to move to the left side of the conveyor belt 33, the driven plate 34 will pass through the air outlet 38. When the driven plate 34 passes through the air outlet 38, the steam between two adjacent driven plates 34 will be drawn into the multiple air outlets 38, and then the steam will be drawn into the conduit 391, and then the steam will enter the vacuum pump 39, and then be discharged from the vacuum pump 39 into the inner cavity 31. After the steam enters the inner cavity 31, the steam will flow in the inner cavity 31. During the flow of the steam, the inner cavity 31 can be heated to prevent the temperature of the inner cavity 31 from being too low, thereby absorbing the heat of the steam passing through the outer cavity 32, and finally the steam in the inner cavity 31 will flow out through the outlet pipe 22.

[0071] Embodiment 2: The air intake supplement mechanism includes an air intake box 4; the air intake box 4 is fixedly mounted on the right side surface of the heating plate 2, and the air intake port 23 is located inside the air intake box 4; a control valve is installed in the air intake port 23;

[0072] The air intake box 4 is provided with evenly arranged air intake pipes 41 at both ends of the two sides; a piston plate 42 is slidably disposed inside the air intake box 4, and a spring is fixedly connected to the right side of the piston plate 42; a sensor 43 is installed on the side wall of the air intake box 4 near the air intake pipe 41;

[0073] In this embodiment, the air intake box 4 is fixedly connected to evenly arranged round tubes 44;

[0074] The round tube 44 passes through the piston plate 42 and is slidably connected to the piston plate 42; a heating wire 45 is installed in each of the round tubes 44, and the heating wire 45 is used to keep the steam in the air intake box 4 warm;

[0075] In this embodiment, a telescopic tube 46 is installed on each of the air inlets 23;

[0076] Each of the telescopic tubes 46 extends to one side of the piston plate 42; each of the telescopic tubes 46 extending to one side of the piston plate 42 is fixedly connected to a ring 47;

[0077] One end surface of each of the circular rings 47 facing the piston plate 42 is fixedly connected to evenly arranged connecting rods 48, and the connecting rods 48 are fixedly connected to the piston plate 42; a distance is left between the telescopic tube 46 and the piston plate 42;

[0078] Specifically, when the steam is introduced, the air inlet pipe 41 is first connected to the external steam pipe, and the control valve in the air inlet 23 is controlled to be closed. When the gas enters the air inlet box 4, the control valve in the air inlet 23 is closed, so the steam entering the air inlet box 4 will gradually increase. Therefore, the gradually increasing steam will push the piston plate 42 to move to the side away from the air inlet 23, and at the same time compress the spring on the right side of the piston plate 42. When the piston plate 42 moves to the extreme position, the control valve in the air inlet 23 is controlled to open. When the control valve is opened, the steam in the air inlet box 4 will enter the outer cavity 32, and then enter the adjacent circulated rotating cavity in turn. Between the two driven plates 34, the spring will push the piston plate 42 to move to the position of the air outlet 38. In this process, since steam is first introduced into the air inlet box 4 and stored, when the rotating driven plate 34 passes the position of the air inlet 23, the piston plate 42 can push the steam into the outer cavity 32, so that the steam can quickly fill the space between the two adjacent driven plates 34, thereby avoiding that the steam cannot fill the space between the two adjacent driven plates 34, resulting in a difference in the amount of steam between every two adjacent driven plates 34, which will cause a difference in the heating temperature of the corrugated paper 12 passing through, resulting in uneven temperature on the corrugated paper 12;

[0079] More specifically, since the sensor 43 is installed on the side wall of the air intake box 4, when the piston plate 42 moves to the left to the position of the sensor 43, when the sensor 43 detects the piston plate 42, the amount of steam in the air intake pipe 41 is increased, so that more steam can be passed into the air intake box 4, so that the steam in the air intake box 4 can be replenished in time, avoiding insufficient steam in the air intake box 4, so that the steam cannot fill the space between the adjacent driven plates 34;

[0080] Furthermore, since the round tube 44 is slidably connected to the piston plate 42, when the piston plate 42 slides, it moves along the round tube 44. At the same time, since a heating wire 45 is installed in the round tube 44, when the steam enters the air intake box 4, the heating wire 45 works, so that the steam in the air intake box 4 can be kept warm, thereby preventing the temperature of the steam from decreasing.

[0081] Furthermore, since the ring 47 fixedly connected to the telescopic tube 46 is fixedly connected to the piston plate 42 through the connecting rod 48, when the piston plate 42 moves, the telescopic tube 46 will be pulled to extend or contract through the connecting rod 48 and the ring 47. At the same time, the steam near the position of the piston plate 42 will first enter the outer cavity 32 through the telescopic tube 46, thereby allowing the steam that first entered the air intake box 4 to flow out.

[0082] Embodiment 3: The driven plate 34 includes a left plate 341 and a right plate 342; the left plate 341 and the right plate 342 are attached to each other and arranged alternately on opposite sides; the left plate 341 and the right plate 342 are extended to the ends of the rotating belt 33 on opposite sides;

[0083] Each of the left plate 341 and the right plate 342 is provided with a slide groove 343 on one side close to the rotating belt 33, and the slide groove 343 is convex; the length of the slide groove 343 is greater than the length of the corresponding left plate 341 or right plate 342;

[0084] The left plate 341 and the right plate 342 are fixedly connected to the convex block 344 on one side close to the rotating belt 33, and the convex block 344 slides in the sliding groove 343;

[0085] A plurality of annular plates 5 are provided on opposite sides of the left plates 341 and the right plates 342, and the annular plates 5 are oblong in shape; the inner ring of the annular plates 5 slides on the rotating belt 33; the outer ring surface of the annular plates 5 fits with the outer cavity 32;

[0086] Two electric push rods 51 are installed on the two sealing plates 21, and the extension rods of the electric push rods 51 extend into the outer cavity 32 and are fixedly connected to the annular plate 5;

[0087] In this embodiment, the side of the plurality of left plates 341 and right plates 342 close to the annular plate 5 is fixedly connected to the ball shaft 52;

[0088] The two annular plates 5 are provided with a slideway 53 on one end surface facing the left plate 341 or the right plate 342, and the slideway 53 is an oblong shape; the cross section of the slideway 53 is C-shaped; the ball shaft 52 slides in the slideway 53;

[0089] In this embodiment, the left plate 341 or the right plate 342 is in contact with the adjacent annular plate 5;

[0090] Specifically, when it is necessary to heat the corrugated paper 12 of different widths, firstly, the distance between the two annular plates 5 is adjusted according to the width of the corrugated paper 12, and the through hole controls the electric push rod 51 to extend or contract, thereby pushing the annular plate 5 to move along the rotating belt 33 to the opposite side or the opposite side, and at the same time, the annular plate 5 will push the left plate 341 and the right plate 342 to move, and the left plate 341 and the right plate 342 will drive the convex block 344 to move in the slide groove 343. When the two annular plates 5 move to the appropriate position according to the width of the corrugated paper 12, the distance between the two annular plates 5 is greater than the width of the corrugated paper 12. In this process, by controlling the distance between the two annular plates 5, the overall length of the driven plate 34 can be adjusted while the distance between the adjacent driven plates 34 remains unchanged, so as to avoid the length of the driven plate 34 being much greater than the width of the corrugated paper 12, thereby causing the steam on both sides of the corrugated paper 12 to fail to act on the corrugated paper 12, resulting in a waste of steam.

[0091] More specifically, since the ball shaft 52 on the left plate 341 and the right plate 342 slides in the slideway 53 opened on the annular plate 5, the left plate 341 and the right plate 342 will rotate along the slideway 53 as they follow the rotation of the conveyor belt 33. When the annular plate 5 moves to the opposite side, the left plate 341 and the right plate 342 will be pulled to move by the ball shaft 52. Since the left plate 341 and the right plate 342 are in contact with the adjacent annular plate 5, the sealing between the left plate 341 or the right plate 342 and the annular plate 5 can be ensured.
