Technical Field

[0001] This utility model relates to the field of corrugated cardboard production technology, specifically a heating and speed-up device for corrugated cardboard production. Background Technology

[0002] In corrugated cardboard production, the core function of heating and speed-up equipment is to solve the problems of "slow adhesive curing, high moisture content of raw paper, and limited production line speed". It achieves two major goals through precise heating: first, to accelerate the gelatinization and cross-linking curing of starch glue (the mainstream adhesive for corrugated cardboard) to ensure strong adhesion between cardboard layers; second, to remove excess moisture from the raw paper and adhesive to ensure that the cardboard stiffness and strength meet the standards, ultimately achieving production line speed-up.

[0003] However, most existing heating and speed-up equipment for corrugated cardboard production is fixed, which means that the heating and speed-up equipment cannot be adjusted according to the different thicknesses of corrugated paper. This results in inadequate contact between the heating area of ​​the heating and speed-up equipment and the surface of the corrugated paper, thus failing to affect the heating effect of the corrugated paper. Therefore, in order to solve the above-mentioned problems, an improved heating and speed-up equipment for corrugated cardboard production has been proposed. Utility Model Content

[0004] The purpose of this invention is to provide a heating and speed-up device for corrugated cardboard production. The position of the heating components can be adjusted by the adjustment mechanisms on both sides of the mounting base to accommodate corrugated paper of different thicknesses, ensuring precise contact of the heating area, improving heating efficiency and uniformity, and guaranteeing the curing of starch adhesive and the removal of moisture. Simultaneously, the limiting component at the connection between the conveyor frame and the mounting base can stably guide the corrugated paper, reducing deviation and ensuring heating stability. This improves the reliability of equipment operation and the quality of the cardboard, enhancing the practicality and applicability of the equipment, thereby solving the problems mentioned in the background art.

[0014] This utility model provides a heating and speed-up device for corrugated cardboard production. By setting adjustment mechanisms on both sides of the mounting base and mounting the heating components on the adjustment mechanisms, the position of the heating components can be flexibly adjusted according to the actual thickness of the corrugated paper.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides, for example Figures 1-4 The heating and speed-up equipment for corrugated cardboard production shown includes a mounting base 1 and a heating component 2. Adjustment mechanisms 3 are provided on opposite sides of the mounting base 1, and the two ends of the heating component 2 are respectively mounted on the adjustment mechanisms 3 on both sides of the mounting base 1.

[0023] It also includes a conveyor frame 4, which is installed at the outlet of the mounting base 1, and a limiting component 5 is provided at the connection between the conveyor frame 4 and the mounting base 1 to guide the corrugated paper.

[0024] According to the thickness of the corrugated paper to be processed, the symmetrical adjustment mechanisms 3 on both sides of the operating mounting base 1 are used to drive the two ends of the heating component 2 to move up and down or back and forth until the heating area of ​​the heating component 2 matches the distance between the corrugated paper surface; then the corrugated paper is fed in from the feeding end of the mounting base 1, heated by the heating component 2, and then conveyed from the discharge port of the mounting base 1 to the conveyor frame 4. During this process, the limiting component 5 at the connection between the mounting base 1 and the conveyor frame 4 will fit against the two sides or the top and bottom of the corrugated paper to constrain and guide the conveying path of the corrugated paper.

[0025] The adjustment mechanism 3 solves the problem that the existing equipment is "fixed and cannot adapt to corrugated paper of different thicknesses". It can flexibly adjust the position of the heating component 2 to ensure that the heating area is in precise contact with the surface of the corrugated paper, avoid incomplete heating, improve heating efficiency and uniformity, and ensure the curing of starch glue and the removal of moisture.

[0026] The limiting component 5 can reduce the offset of corrugated paper during conveying and heating, avoid local overheating or underheating due to positional offset, ensure the stability of heating operation, and indirectly improve the quality of paperboard production.

[0027] The overall structure takes into account both "heating regulation" and "conveyor guidance", adapting to the production of corrugated paper of various thicknesses, thus enhancing the practicality and applicability of the equipment.

[0028] The adjustment mechanism 3 includes a fixed frame 31 and a movable frame 32. The heating component 2 is installed on the fixed frame 31 and the movable frame 32 respectively. The fixed frame 31 is fixed to the bottom of the inner side of the mounting base 1. Hydraulic rods 33 are installed at both ends of the fixed frame 31. The piston rod of the hydraulic rod 33 is fixedly connected to the movable frame 32. The movable frame 32 is installed at the upper end of the inner side of the mounting base 1 and is located above the fixed frame 31.

[0029] When it is necessary to adjust the position of the heating component 2, the hydraulic rods 33 installed at both ends of the fixed frame 31 at the bottom inside the mounting base 1 are activated. The piston rod of the hydraulic rod 33 will extend or retract, driving the movable frame 32 (installed at the upper inside of the mounting base 1, located above the fixed frame 31) which is fixedly connected to it to move up and down. Since the heating components 2 are installed on the fixed frame 31 and the movable frame 32 respectively, when the movable frame 32 moves, it will synchronously drive the upper heating component 2 to move closer to or away from the heating component 2 on the fixed frame 31, thereby adjusting the distance between the two sets of heating components 2 to adapt to corrugated paper of different thicknesses.

[0030] The moving frame 32 is driven by a hydraulic rod 33. Compared with manual adjustment or other driving methods, the adjustment accuracy is higher and the driving force is more stable. It can accurately control the spacing of the heating components 2 and adapt to corrugated paper of different specifications from thin to thick, avoiding the impact of spacing deviation on the heating effect.

[0031] The fixed frame 31 and the movable frame 32 are arranged vertically and vertically to make the heating components 2 symmetrically distributed vertically. When the corrugated paper passes through the middle, it can be heated from both the top and bottom sides at the same time, which improves the heating uniformity and further shortens the curing time of the starch adhesive.

[0032] The adjustment mechanism 3 also includes a slide groove 34 and a slider 35. The slider 35 is fixedly connected to both ends of the movable frame 32. The slide groove 34 is opened on the inner side wall of the mounting base 1 and corresponds to the position of the slider 35. The slider 35 is slidably connected within the slide groove 34.

[0033] When the movable frame 32 is driven to move by the hydraulic rod 33, the sliders 35 fixed at both ends of the movable frame 32 will be simultaneously embedded into the corresponding grooves 34 opened on the inner side wall of the mounting base 1, and slide along the extension direction of the grooves 34 (usually the up and down direction); the cooperation between the sliders 35 and the grooves 34 will limit the movement trajectory of the movable frame 32, and prevent the movable frame 32 from shifting left and right or swaying during the up and down movement.

[0034] The sliding engagement between the slider 35 and the slide groove 34 provides a stable guiding constraint for the moving frame 32, preventing the moving frame 32 from shifting due to uneven driving force of the hydraulic rod 33 or impact from corrugated paper conveying, ensuring accurate adjustment of the spacing of the heating components 2, and avoiding misalignment of the heating area.

[0035] Multiple springs 36 are fixedly connected to the opposite sides of the fixed frame 31 and the movable frame 32, and the specific lengths between any two adjacent springs 36 are all equal.

[0036] When the corrugated paper passes through the heating component 2 between the fixed frame 31 and the movable frame 32, multiple equally spaced springs 36 fixed on opposite sides of the fixed frame 31 and the movable frame 32 will slightly adhere to the upper and lower surfaces of the corrugated paper (or the outer shell of the heating component 2); if there is a slight thickness fluctuation in the corrugated paper, the springs 36 will adaptively adjust through their own elastic expansion and contraction, always maintaining contact with the corrugated paper or the heating component 2, while buffering the pressure of the heating component 2 on the corrugated paper;

[0037] The evenly spaced springs 36 provide uniform elastic support, avoiding uneven local contact pressure caused by slight fluctuations in the thickness of the corrugated paper, ensuring that the heating component 2 and the surface of the corrugated paper always remain in stable contact, and improving heating uniformity.

[0038] The elastic cushioning effect of spring 36 can prevent the heating component 2 from applying excessive pressure to the corrugated paper, avoid crushing or deforming the corrugated paper, and protect the structural integrity of the cardboard.

[0039] The heating assembly 2 includes a heating roller 21 and a power supply module 22. The power supply module 22 is installed on the inner wall of the mounting base 1. The heating roller is installed on the movable frame 32 and the fixed frame 31 respectively. The two ends of the heating roller are electrically connected to the power supply module 22. A controller 23 for controlling the power supply module 22 is installed on the outer wall of one side of the mounting base 1.

[0040] After the equipment is started, the heating temperature is set by the controller 23 installed on the outer wall of the mounting base 1 (adjusted according to the thickness of the corrugated paper and the type of starch adhesive). The controller 23 sends a command to the power supply module 22 installed on the inner wall of the mounting base 1. The power supply module 22 then supplies electrical energy of corresponding power to the heating roller 21 installed on the moving frame 32 and the fixed frame 31. After the heating roller 21 is powered on, it heats up to the set temperature. During the corrugated paper conveying process, the heating roller 21 is in contact with or near the surface of the corrugated paper for heating. At the same time, the output power of the power supply module 22 can be finely adjusted in real time by the controller 23 to control the temperature of the heating roller 21.

[0041] The heating roller 21 directly contacts or heats the corrugated paper at close range. Compared with hot air heating and other methods, the heat transfer efficiency is higher, which can quickly accelerate the gelatinization and cross-linking of starch glue, shorten the curing time, and help speed up the production line.

[0042] The controller 23 works in conjunction with the power supply module 22 to achieve precise temperature control. The heating temperature can be adjusted according to different production needs (such as different thicknesses of corrugated paper, different humidity environments) to avoid excessively high temperatures causing paperboard carbonization, excessive dryness and brittleness, or excessively low temperatures causing insufficient curing of starch glue.

[0043] The heating roller 21 is located on the movable frame 32 and the fixed frame 31, and is linked with the adjustment mechanism 3. It can adjust the spacing of the heating components 2 to maintain the heating coverage of the corrugated paper, ensuring that corrugated paper of different thicknesses can be heated stably and ensuring consistent heating effect.

[0044] The limiting component 5 includes a positioning rod 51, with connecting plates 52 fixedly connected to both ends of the positioning rod 51. The two ends of the connecting plates 52 are respectively fixed to the fixed frame 31 and the conveyor frame 4.

[0045] The two ends of the positioning rod 51 are fixed to the fixed frame 31 and the conveyor frame 4 respectively through the connecting plate 52, so that the positioning rod 51 spans across the connection between the discharge port of the mounting base 1 and the conveyor frame 4, and the position of the positioning rod 51 corresponds to the conveying path of the corrugated paper. When the corrugated paper is sent out from the discharge port of the mounting base 1, it will pass through the inside of the positioning rod 51 (or the gap between the positioning rods 51). The positioning rod 51 will prevent the corrugated paper from shifting to both sides and guide it to accurately enter the conveyor frame 4. The positioning rod 51 directly plays a physical constraint and guiding role on the corrugated paper, which solves the problem of "easy deviation of the conveying path" at the connection between the mounting base 1 and the conveyor frame 4, avoids the corrugated paper from getting stuck in the connection gap or deviating from the conveyor frame 4, and reduces production downtime.

[0046] The positioning rods 51 are divided into upper and lower groups, with at least two positioning rods 51 in each group. The upper and lower groups of positioning rods 51 guide the corrugated paper from both directions. Compared with a single-direction positioning structure, it can more comprehensively constrain the conveying posture of the corrugated paper, prevent the corrugated paper from warping up and down or shifting left and right, and improve the conveying stability.

[0047] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
