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.

[0037] 1. For a steam device for corrugated paper processing and bonding according to the present invention, since steam fills the space between two adjacent driven plates, heating can be performed on the entire width direction of the passing corrugated paper. Thus, it can avoid the situation in the prior art where when heating the corrugated paper in an S-shaped circulating flow manner, the temperature on the corrugated paper is uneven. Also, since the moving direction of the steam is opposite to the moving direction of the corrugated paper, the steam moving from right to left can heat the corrugated paper for a long time. When the heat decays during the movement of the steam from right to left, the decayed heat can also preheat the corrugated paper on the left side. Moreover, since the circulating rotating driven plates will drive the steam to move along the corrugated paper from right to left in a cycle, and the moving speed of the steam is the same, while ensuring the corrugated paper moves at a constant speed, it can ensure that the temperature of the passing corrugated paper heated by the steam is relatively uniform, thus avoiding uneven temperature on the corrugated paper.

[0038] 2. For a steam device for corrugated paper processing and bonding according to the present invention, since steam is first introduced into the air inlet box and stored, when the rotating driven plate passes through 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, thus 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, and thus causing a difference in the heating temperature of the passing corrugated cardboard, leading to uneven temperature on the corrugated paper.

[0039] 3. For a steam device for corrugated paper processing and bonding according to the present invention, by controlling the distance between two annular plates, the overall length of the driven plate can be adjusted without changing the distance between adjacent driven plates, avoiding the situation where the length of the driven plate is much larger than the width of the corrugated paper, resulting in the steam on both sides of the corrugated paper being unable to act on the corrugated paper and causing waste of steam.

[0053] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

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

[0055] It includes a frame 1; rotating rollers 11 are rotatably installed above both sides of the frame 1 and are evenly arranged, and the rotating rollers 11 are used for transporting corrugated paper 12;

[0056] In the middle of the frame 1, two heating plates 2 arranged in a mirror image of each other are installed. The corrugated paper 12 after applying glue will pass between the two heating plates 2, and the heating plates 2 will heat the passing corrugated paper 12.

[0057] Both ends of the two sides of the two heating plates 2 are fixedly connected with sealing plates 21.

[0058] Support plates 13 are installed on the sealing plates 21 on both sides of the upper heating plate 2; a hydraulic cylinder 14 is fixedly connected to the lower surface of each support plate 13, 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] Oval-shaped grooves are formed inside the two heating plates 2; a flow guiding assembly is arranged in each of the two oval-shaped grooves, and the flow guiding assembly is used to guide the steam.

[0061] Uniformly arranged air inlet openings 23 are formed on the right sides of the two heating plates 2; an air inlet supplement mechanism is arranged on the right sides of the two heating plates 2, and the air inlet supplement mechanism is used to supplement the steam.

[0062] In this embodiment, the flow guiding assembly includes an annular chamber 3, and the annular chamber 3 is oval-shaped.

[0063] The annular chamber 3 is fixedly connected in the oval-shaped groove, and divides the oval-shaped groove into an inner cavity 31 and an outer cavity 32. The air inlet opening 23 is communicated with the outer cavity 32, and the air outlet pipe 22 is communicated with the inner cavity 31.

[0064] A rotating belt 33 is rotatably connected to the outer circumferential surface of the annular chamber 3; uniformly arranged driven plates 34 are installed on the outer circumferential surface of the rotating belt 33, and the tops of the driven plates 34 are in contact with the surface of the outer cavity 32.

[0065] Driving rollers 35 are rotatably connected to both sides of the annular chamber 3, and the driving rollers 35 are in contact with the inner circumferential 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 formed 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; uniformly arranged air outlet openings 38 are formed in the cylindrical groove 37, and the air outlet openings 38 are communicated with the outer cavity 32. The air outlet openings 38 are located on the left side of the outer cavity 32, and the air inlet opening 23 is located on the right side of the outer cavity 32.

[0067] An air extraction pump 39 is installed in the inner cavity 31, and the air extraction pump 39 is installed on the sealing plate 21 without the air outlet pipe 22; a conduit 391 is installed on the sealing plate 21 without the air outlet pipe 22, and one end of the conduit 391 is communicated with the cylindrical groove 37, and the other end is communicated with the air extraction pump 39.

[0068] Specifically, after the corrugated paper 12 is coated with an adhesive and bonded, the corrugated paper 12 is transported through the rotating roller 11. The corrugated paper 12 transported by the rotating roller 11 passes 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, which will drive the upper heating plate 2 to move, so as to adjust the distance between the two heating plates 2. Before heating the corrugated paper 12, external steam is first introduced into the air intake supplement mechanism. The steam entering the air intake supplement mechanism will be introduced into the outer cavity 32 of the heating plate 2. At the same time, the servo motors 36 on the two heating plates 2 are controlled to rotate. The servo motors 36 will drive the conveyor belts 33 in the two heating plates 2 to rotate in a circulating and slow manner. The conveyor belt 33 in the lower heating plate 2 will rotate counterclockwise along the annular bin 3, and the conveyor belt 33 in the upper heating plate 2 will rotate clockwise along the annular bin 3. At the same time, the two conveyor belts 33 respectively drive the driven plates 34 to rotate in a circulating manner. Since the driven plates 34 are in contact with the surface of the outer cavity 32, a closed space can be formed between two adjacent driven plates 34;

[0069] More specifically, when the slowly rotating driven plate 34 passes through the air intake port 23, at this time, the air intake supplement mechanism will introduce the internal steam into the space between two adjacent driven plates 34. When the space between two adjacent driven plates 34 is filled with steam, the gas in the air intake supplement mechanism will no longer enter the space between two adjacent driven plates 34. Subsequently, the driven plate 34 located behind will pass through the air intake port 23 position, and then the air intake supplement mechanism will introduce steam into the space between two adjacent driven plates 34 behind. When two adjacent driven plates 34 pass through the air outlet 38, they will drive the steam between the adjacent driven plates 34 to move, and will move from right to left on the upper and lower sides of the corrugated paper 12. When the corrugated paper 12 passes between the two heating plates 2, the steam moving from right to left will heat the corrugated paper 12 at this time. Since the steam fills the space between two adjacent driven plates 34, the entire width direction of the passing corrugated paper 12 can be heated, thus avoiding the situation of uneven temperature on the corrugated paper 12 when the corrugated paper 12 is heated by the S-shaped circulating flow method in the prior art. Also, since the moving direction of the steam is opposite to the moving direction 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 decays during the process of the steam moving from right to left, the decayed heat can also preheat the corrugated paper 12 on the left side. Also, since the circulating rotating driven plates 34 will drive the steam to move from right to left along the corrugated paper 12 in a circulating manner, and the moving speed of the steam is the same, and at the same time ensuring that the corrugated paper 12 moves at a constant speed, the temperature of the passing corrugated paper 12 heated by the steam can be relatively uniform, thus 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 rotating belt 33, at this time, the driven plate 34 will pass by the air outlet 38. When the driven plate 34 passes by 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 air extraction pump 39, and then be discharged into the inner cavity 31 from the air extraction pump 39. When 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, so as to prevent the temperature of the inner cavity 31 from being too low, and thus absorb the heat of the steam passing through the outer cavity 32. Finally, the steam located in the inner cavity 31 will flow out through the air outlet pipe 22.

[0071] Embodiment 2: The air intake supplement mechanism includes an air intake box 4; the air intake box 4 is fixedly installed on the right 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] Both ends of the air intake box 4 are installed with evenly arranged intake pipes 41; a piston plate 42 slides in the air intake box 4, and the right side of the piston plate 42 is fixedly connected with a spring; a sensor 43 is installed on one side of the side wall of the air intake box 4 close to the intake pipe 41;

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

[0074] The round tubes 44 pass through the piston plate 42 and are slidably connected with the piston plate 42; heating wires 45 are installed in the round tubes 44, and the heating wires 45 are used to keep the steam in the air intake box 4 warm;

[0075] In this embodiment, a telescopic tube 46 is installed on each air intake port 23;

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

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

[0078] Specifically, when introducing steam, first connect the intake pipe 41 to the external steam pipe, and at the same time control the control valve in the air inlet 23 to close. When the gas enters the intake box 4, since the control valve in the air inlet 23 is closed, the steam entering the intake 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 limit position, at this time control the control valve in the air inlet 23 to open. After the control valve is opened, the steam in the intake box 4 will enter the outer cavity 32, and then enter between two adjacent driven plates 34 that rotate in sequence. At the same time, the spring will push the piston plate 42 to move towards the air outlet 38. During this process, since steam is first introduced into the intake box 4 and stored, when the rotating driven plate 34 passes through 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 two adjacent driven plates 34, thus avoiding the situation that the steam cannot fill the space between two adjacent driven plates 34, resulting in a difference in the amount of steam between every two adjacent driven plates 34, and thus causing a difference in the heating temperature of the corrugated paper 12 board passing through, resulting in uneven temperature on the corrugated paper 12;

[0079] More specifically, since a sensor 43 is installed on the side wall of the intake box 4, when the piston plate 42 moves left to the position of the sensor 43, when the sensor 43 detects the piston plate 42, at this time increase the amount of steam in the intake pipe 41, so that more steam can be introduced into the intake box 4, thus timely supplementing the steam in the intake box 4 and avoiding insufficient steam in the intake box 4, so that the steam cannot fill the space between adjacent driven plates 34;

[0080] Furthermore, since the circular tube 44 is slidably connected to the piston plate 42, when the piston plate 42 slides, it will move along the circular tube 44. At the same time, since a heating wire 45 is installed in the circular tube 44, when the steam enters the intake box 4, at this time the heating wire 45 works, so that the steam in the intake box 4 can be kept warm, thus avoiding the decrease in the temperature of the steam;

[0081] Even further, 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, it will pull the telescopic tube 46 to extend or contract through the connecting rod 48 and the ring 47. At the same time, the steam near the piston plate 42 will first enter the outer cavity 32 through the telescopic tube 46, so that the steam that first enters the intake box 4 flows out.

[0082] Embodiment 3: The driven plate 34 includes a left plate 341 and a right plate 342; the opposite sides of the left plate 341 and the right plate 342 are mutually attached and staggered; the opposite sides of the left plate 341 and the right plate 342 respectively extend to the ends of the conveyor belt 33;

[0083] On one side of each of the left plate 341 and the right plate 342 close to the conveyor belt 33, a chute 343 is provided, and the chute 343 is convex; the length of the chute 343 is greater than the length of the corresponding left plate 341 or right plate 342;

[0084] On one side of the left plate 341 and the right plate 342 close to the conveyor belt 33, a convex block 344 is fixedly connected, and the convex blocks 344 are all slidably arranged in the chutes 343;

[0085] On the opposite sides of a plurality of the left plates 341 and the right plates 342, an annular plate 5 is provided, and the annular plate 5 is oblong; the inner ring of the annular plate 5 is slidably arranged on the conveyor belt 33; the outer circumferential surface of the annular plate 5 is attached to the outer cavity 32;

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

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

[0088] On one end face of each of the two annular plates 5 facing the left plate 341 or the right plate 342, a slideway 53 is provided, and the slideway 53 is oblong; the cross section of the slideway 53 is C-shaped; the ball shaft 52 is slidably arranged in the slideway 53;

[0089] In this embodiment, the left plate 341 or the right plate 342 is attached to the adjacent annular plate 5;

[0090] Specifically, when it is necessary to heat corrugated paper 12 with different widths, first, adjust the distance between the two annular plates 5 according to the width of the corrugated paper 12, control the electric push rods 51 to extend or contract, so as to push the annular plates 5 to move towards the opposite side or the back side along the conveyor belt 33. At the same time, the annular plates 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 blocks 344 to move in the chutes 343. When the two annular plates 5 move to appropriate positions according to the width of the corrugated paper 12, the distance between the two annular plates 5 at this time should be greater than the width of the corrugated paper 12. During this process, by controlling the distance between the two annular plates 5, the overall length of the driven plates 34 can be adjusted without changing the distance between adjacent driven plates 34, avoiding the situation that the length of the driven plates 34 is much greater than the width of the corrugated paper 12, resulting in the steam on both sides of the corrugated paper 12 being unable to act on the corrugated paper 12 and causing waste of steam;

[0091] More specifically, since the ball shafts 52 on the left plate 341 and the right plate 342 slide in the slideways 53 formed on the annular plate 5, during the rotation of the left plate 341 and the right plate 342 following the conveyor belt 33, they will rotate along the slideways 53. When the annular plate 5 moves towards the opposite sides, the left plate 341 and the right plate 342 will be pulled to move through the ball shafts 52. Since the left plate 341 and the right plate 342 are in contact with the adjacent annular plate 5, the sealing performance between the left plate 341 or the right plate 342 and the annular plate 5 can be ensured.

[0092] The foregoing has shown and described the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments, and what is described in the above embodiments and the specification is only to illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and all these changes and improvements fall within the scope of the present invention claimed.
