Description

Technical Field

[0001] This utility model relates to the field of paperboard dehumidification technology, and more specifically, it relates to a dehumidification device for paperboard processing. Background Technology

[0002] In the existing paperboard processing technology field, the dehumidification process is a crucial quality control link in the paperboard forming process. Its equipment performance and process stability directly affect key quality indicators of paperboard products, such as moisture content uniformity, flatness, and strength. However, existing paperboard dehumidification devices on the market generally suffer from insufficient positioning accuracy during actual production applications. Specifically, during the continuous conveying process of paperboard through the dehumidification device for moisture removal, the paperboard is easily affected by various factors as it moves along a preset path driven by the conveyor belt or rollers, resulting in lateral or longitudinal positional deviations. When the paperboard deviates during conveying, its position relative to the dehumidification vents inside the dehumidification device... The spatial relationship between the hot air nozzles or the negative pressure adsorption area will deviate from the optimal process parameters, resulting in differences in the intensity of dehumidification in different areas of the cardboard. The edges of the cardboard in the offset direction may be overexposed to the dehumidifying airflow, causing over-drying and even quality defects such as edge curling, warping, and embrittlement. On the other hand, the edges of the cardboard in the opposite offset direction may have excessively high local moisture content due to insufficient dehumidification, leading to a series of quality problems such as poor die-cutting, printing smudging, and decreased bonding strength in subsequent processing. This causes the moisture content of cardboard in different locations of the same batch to fluctuate beyond the industry quality standard requirements. This quality instability increases the difficulty of process adjustment in subsequent production stages and the scrap rate. Utility Model Content

[0003] (a) Technical problems to be solved In view of the problems existing in the prior art, this utility model provides a dehumidification device for cardboard processing to solve the technical problems mentioned in the background art.

[0004] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: A dehumidification device for cardboard processing includes a mounting plate, wherein two sets of mounting plates are provided, and a first conveyor belt, a second conveyor belt, and a third conveyor belt are rotatably connected between the two sets of mounting plates. The second conveyor belt is located between the first and third conveyor belts and is longer than the first and third conveyor belts. The device also includes an adjustable clamping mechanism, wherein the adjustable clamping mechanism includes a fixed cylinder, the surface of which has two sets of slots, and the outer wall of which has two sets of guide plates, the guide plates having sliding grooves.

[0005] Preferably, four sets of follower rollers are rotatably connected to the upper surface of the two sets of mounting plates. The four sets of follower rollers are located above the second conveyor belt. Two sets of auxiliary belts are sleeved at both ends of each pair of follower rollers. The auxiliary belts cooperate with the second conveyor belt and effectively prevent the cardboard from warping, wrinkling or lateral movement during the dehumidification process by clamping it from above and below, thereby improving the positional stability and dehumidification uniformity of the cardboard conveying.

[0006] Preferably, the upper surface of the mounting plate is provided with two sets of dehumidifying fans, each set of dehumidifying fans being located above the corresponding auxiliary belt, and the dehumidifying fans blowing air to dry the cardboard.

[0007] Preferably, a lower discharge roller is rotatably connected between the mounting plates, and an upper discharge roller is rotatably connected to the upper end face of the mounting plates. The upper discharge roller cooperates with the lower discharge roller and is located between the second conveyor belt and the third conveyor belt, thereby realizing a smooth transition of the paperboard from the dehumidification zone to the discharge zone.

[0008] Preferably, the fixing cylinder has two sets, which are respectively installed on the upper surface of the mounting plate. An adjusting rod is slidably connected inside the fixing cylinder. Multiple adjusting grooves are opened on the surface of the adjusting rod. The other end of the adjusting rod is connected to a clamping plate, which realizes the range adjustment of the clamping plate position and multi-position locking, enabling the device to quickly adapt to cardboard of different width specifications, improving the versatility and changeover efficiency of the equipment.

[0009] Preferably, two sets of conical blocks are slidably connected in the groove, and two sets of locking rods are slidably connected in each groove. One end of each set of locking rods is connected to a push plate, and both ends of the push plate are connected to locking plates that are adapted to the conical blocks. A connecting spring is provided on the side wall of the push plate, and the other end of the connecting spring is fixedly connected to the outer wall of the fixed cylinder. The wedge self-locking principle realizes quick unlocking by pressing and elastic reset locking. The operation is simple and requires no tools, which simplifies the adjustment process and ensures the reliability of locking.

[0010] Preferably, a first pressure ring is connected to one side wall of the conical block, and a second pressure ring is connected to the other side wall of the conical block, providing the operator with an easy-to-grip and force-applying operating interface, making the opposite movement of the conical blocks more intuitive and convenient, and further improving the ease of operation of the adjustable clamping mechanism.

[0011] (III) Beneficial Effects Compared with the prior art, this utility model provides a dehumidification device for cardboard processing, which has the following advantages: This dehumidification device for cardboard processing solves the problems of positional deviation, uneven dehumidification, and poor adaptability that are common in traditional dehumidification devices during continuous cardboard conveying by using a three-section gradient conveying system combined with an adjustable clamping mechanism for positioning and correction. The three-section conveyor belt layout adopts a series relay transmission method of the first, second, and third conveyor belts, which rationally separates the three process stages of cardboard feeding, dehumidification, and discharging in space. The second conveyor belt is designed to be longer than the first and third conveyor belts. This provides the cardboard with ample dehumidification time and a stable support platform, ensuring that the cardboard can maintain a stable conveying speed and position during the critical moisture removal stage. The four sets of follower rollers rotatably connected to the upper surface of the two sets of mounting plates, together with the two sets of auxiliary belts fitted at both ends, form a double-layer pressing conveying system. The auxiliary belts apply uniform pressure from the upper surface of the cardboard to make the cardboard tightly adhere to the surface of the second conveyor belt. Compared with the traditional single-sided support conveying method, this upper and lower clamping conveying method can improve the stability of cardboard conveying and effectively prevent the cardboard from warping, wrinkling, lateral movement and other positional deviations caused by insufficient flatness, uneven moisture distribution or external interference. The adjustable clamping mechanism achieves flexible adjustment of the cardboard conveying path positioning and width range through a modular combination design of a fixed cylinder, adjusting rod, and clamping plate. Two sets of slots on the surface of the fixed cylinder, combined with the sliding grooves within two sets of guide plates on the outer wall, form a bidirectional guiding position adjustment system. The sliding connection of the adjusting rod within the fixed cylinder allows the clamping plate to be adjusted within a wide range. Multiple adjusting grooves on the surface of the adjusting rod provide multiple position locking options, enabling the device to quickly adapt to cardboard of different widths without replacing parts. Two sets of conical blocks slidingly connected within the grooves, along with a locking rod and push plate slidingly connected within the slots, constitute a quick locking and unlocking mechanism based on the wedge self-locking principle. The conical surface structure of the conical blocks and the fitting design of the locking plate achieve radial pressure... To convert the axial thrust, the operator only needs to manually press the first and second pressure rings connected to the side wall of the conical block to make them move towards each other. Under the guidance of the sliding groove, the two conical blocks retract synchronously towards the center position. Their conical surfaces generate an outward thrust on the clamping plate, driving the push plate and clamping rod to move to the outside of the fixed cylinder. The clamping rod slides along the slot and disengages from the clamping state with the adjustment groove, releasing the position lock of the adjustment rod. This press-type quick unlocking mechanism has the advantages of simple operation, rapid response, and no tools required compared with the traditional bolt fastening or pin insertion and removal method. After the position of the adjustment rod is adjusted, the operator releases the pressure rings, and the rebound force of the connecting spring drives the push plate, clamping plate and clamping rod to reset. The clamping rod is reinserted into the corresponding adjustment groove to lock the adjustment rod, which simplifies the operation process and ensures the reliability of the lock. As the cardboard is conveyed from the first conveyor belt to the second conveyor belt and passes between the two sets of clamps, the clamps apply a slight guiding constraint force to the edges of the cardboard on both sides, correcting any lateral deviation that may occur during the initial conveying process. This ensures that the cardboard is accurately aligned with the center line of the second conveyor belt and enters the dehumidification working area. This active correction mechanism at the inlet eliminates the potential for cardboard misalignment at the source. The adjustable design of the clamps also allows the device to be compatible with various specifications of products, from thin corrugated cardboard to thick industrial cardboard. A single unit can meet the needs of flexible production of multiple varieties and small batches, improving the versatility and utilization of the equipment. Attached Figure Description

[0017] Please see Figures 1-5 A dehumidification device for cardboard processing includes mounting plates 11, with two sets of mounting plates 11. A first conveyor belt 12, a second conveyor belt 13, and a third conveyor belt 14 are rotatably connected between the two sets of mounting plates 11. The second conveyor belt 13 is located between the first conveyor belt 12 and the third conveyor belt 14, and is longer than the first conveyor belt 12 and the third conveyor belt 14. Four sets of follower rollers 15 are rotatably connected to the upper surfaces of the two sets of mounting plates 11, and are located above the second conveyor belt 13. Two sets of auxiliary belts 16 are sleeved at both ends of every two sets of follower rollers 15. Two sets of dehumidifying fans 17 are provided on the upper surface of the mounting plates 11, and each set of dehumidifying fans 17 is located above the corresponding auxiliary belt 16. A lower discharge roller 18 is rotatably connected between the mounting plates 11, and an upper discharge roller 19 is rotatably connected to the upper surface of the mounting plates 11. The upper discharge roller 19 cooperates with the lower discharge roller 18 and is located between the second conveyor belt 13 and the third conveyor belt 14. The device also includes an adjustable... The clamping mechanism, an adjustable clamping mechanism, includes a fixed cylinder 21. Two sets of slots 22 are formed on the surface of the fixed cylinder 21. Two sets of guide plates 23 are provided on the outer wall of the fixed cylinder 21. Sliding grooves 24 are formed within the guide plates 23. Two sets of fixed cylinders 21 are respectively installed on the upper surface of the mounting plate 11. An adjusting rod 25 is slidably connected inside the fixed cylinder 21. Multiple adjusting grooves 26 are formed on the surface of the adjusting rod 25. The other end of the adjusting rod 25 is connected to a clamping plate 213, which slides within the sliding grooves 24. Two sets of conical blocks 27 are connected, and two sets of locking rods 28 are slidably connected in each set of slots 22. One end of each set of locking rods 28 is connected to a push plate 29, and both ends of the push plate 29 are connected to locking plates 210 that are adapted to the conical blocks 27. A connecting spring 214 is provided on the side wall of the push plate 29, and the other end of the connecting spring 214 is fixedly connected to the outer side wall of the fixed cylinder 21. A first pressure ring 211 is connected to the side wall of one conical block 27, and a second pressure ring 212 is connected to the side wall of the other conical block 27.

[0018] In this invention, the first conveyor belt 12, the second conveyor belt 13, and the third conveyor belt 14 are all driven by motors. Before the dehumidification operation begins, the adjusting rod 25 needs to be adjusted to adjust the distance between the two sets of clamping plates, thereby adapting to different cardboard sizes. Specifically, the operator manually presses the first pressure ring 211 and the second pressure ring 212 so that they move towards each other. The first pressure ring 211 and the second pressure ring 212 respectively drive the corresponding conical blocks 27 to move towards each other along the slide groove 24, thereby squeezing the corresponding clamping plate 210. The clamping plate 210, under pressure, drives the push plate 29 and the clamping rod 28 to move synchronously outward from the fixed cylinder 21. The lever 28 slides along the slot 22 and disengages from the adjustment slot 26, thereby releasing the fixed state of the adjustment lever 25. At this time, the connecting spring 214 is stretched. Then, the adjustment lever 25 can be adjusted according to the size of this batch of cardboard to be dehumidified, so that the distance between the two sets of clamps matches the size of the cardboard. After that, the worker releases the pressure on the first pressure ring 211 and the second pressure ring 212. The connecting spring 214 rebounds and drives the push plate 29, together with the clamping plate 210 and the lever 28, to reset. The first pressure ring 211 and the second pressure ring 212 are also reset under pressure. The lever 28 is inserted into the corresponding adjustment slot 26 again to fix the adjustment lever 25. Afterwards, the cardboard to be dehumidified is conveyed to the first conveyor belt 12, and then from the first conveyor belt 12 to the second conveyor belt 13. The cardboard passes through two sets of clamps, and under the action of the clamps, the cardboard is adjusted to the correct position. Then the cardboard enters between the auxiliary belt 16 and the second conveyor belt 13, where it is dried by the first set of dehumidifying fans 17. After that, it enters between the second set of auxiliary belt 16 and the second conveyor belt 13, where it is dried by the second set of dehumidifying fans 17. After two rounds of dehumidification, the cardboard enters the third conveyor belt 14 through the upper discharge roller 19 and the lower discharge roller 18, and then enters the next process, thus completing the dehumidification work of a set of cardboard.
