Description

Technical Field

[0001] This utility model relates to an adjustable pressure vertical dry roller device, belonging to the field of mechanical engineering technology. Background Technology

[0002] With the continuous development of industrial automation and precision manufacturing technologies, the requirements for material control in the production process are becoming increasingly stringent. In many production lines, the efficient and precise control of material drying, calendering, and surface treatment makes dry roller devices an important component for improving product quality and production efficiency.

[0003] Traditional dry roller systems typically rely on mechanical methods or simple manual adjustments to control roller pressure. This results in low adjustment precision and difficulty in achieving accurate automated control. Furthermore, the fixed or limited pressure range makes adjustments cumbersome and slow to respond quickly when dealing with different materials or process requirements. Secondly, current dry roller systems often employ a transverse layout, which not only occupies significant space but also limits space and equipment arrangement in certain production environments, impacting the overall layout and efficiency of the production line. In addition, uneven pressure distribution can occur, especially when processing large-format strips, leading to uneven material drying and calendering, ultimately affecting the quality of the final product.

[0004] Therefore, it is necessary to design a new type of adjustable pressure vertical dry roller device that can flexibly adjust the pressure according to different strip requirements, effectively remove liquid from the strip surface, and adopt a vertical design that occupies little space, thereby meeting the requirements for applicability and effectiveness in strip processing.

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] like Figure 1-4As shown, this utility model discloses an adjustable pressure vertical drying roller device, comprising a support housing 1, a squeezing roller assembly 2, and a pressure regulating cylinder 3. The squeezing roller assembly 2 is installed inside the support housing 1 and is connected to the pressure regulating cylinder 3. The pressure regulating cylinder 3 is installed on the outer wall of the support housing 1. The squeezing roller assembly 2 includes a fixed squeezing roller 211 and a movable squeezing roller 212 connected to the pressure regulating cylinder 3. A positioning screw 11 is also provided on the outer wall of the support housing 1, and the positioning screw 11 is connected to the fixed squeezing roller 211. Through the connection between the pressure regulating cylinder 3 and the movable squeezing roller 212, the movable squeezing roller 212 can accurately adjust the roller pressure and movement position with the adjusting cylinder, ensuring pressure stability and consistency during the drying process and improving production quality. At the same time, the cooperative design of the positioning screw 11 and the fixed squeezing roller 211 allows the fixed squeezing roller 211 to be moved to a suitable position by adjusting the screw, and then fixed after the position is determined, preventing displacement and improving the reliability and stability of the equipment.

[0023] The outer wall of the support housing 1 is provided with an inspection window 6, which is positioned corresponding to the squeeze roller assembly 2. This window allows operators to inspect, maintain, and clean the equipment without disassembling the entire machine, significantly reducing downtime and improving production efficiency. Furthermore, the simplified and efficient maintenance process enables operators to quickly troubleshoot and resolve problems, minimizing downtime caused by equipment malfunctions and thus lowering overall maintenance costs.

[0024] The pressure regulating cylinder 3 is equipped with multiple support rods 4 to evenly distribute the force on the cylinder 3, reduce pressure concentration at a single support point, ensure greater stability of the pressure regulating cylinder 3 during operation, and prevent equipment damage or unstable operation due to excessive stress. Furthermore, the multiple support rods 4 can improve the load-bearing capacity of the entire pressure regulating cylinder 3 system, especially when subjected to large pressures or impacts, effectively distributing the load and improving the system's reliability and service life.

[0025] The pressure regulating cylinder 3 includes a first cylinder 311 and a second cylinder 312, which are respectively installed at both ends of the movable squeeze roller 212 to achieve uniform pressure distribution. By independently controlling the cylinders at both ends, it can be ensured that the forces at both ends of the movable squeeze roller 212 are symmetrical, avoiding uneven compression or deformation, and improving the working accuracy and drying effect of the squeeze roller.

[0026] The squeeze roller assembly 2 is also equipped with an adjustable scale measuring ruler 5 to help operators accurately adjust the pressure or gap of the squeeze rollers. Through the visual reference provided by the scale, operators can more accurately set and monitor the working status of the squeeze rollers, ensuring consistency and accuracy in each operation, reducing human error, and improving the repeatability and stability of the production process.

[0027] The squeeze roller group 2 consists of two groups: a first squeeze roller group 21 and a second squeeze roller group 22. The first squeeze roller group 21 is vertically downward-facing, with the second squeeze roller group 22 positioned opposite it. Correspondingly, there are also two pressure regulating cylinders 3: a first pressure regulating cylinder 31 and a second pressure regulating cylinder 32, used to independently adjust the pressure of the two squeeze roller groups. This allows for precise control of the pressure and clamping force of each roller group during operation, based on different production needs and process requirements, providing more flexible and precise adjustment functions. Furthermore, the configuration of two squeeze roller groups 2 and pressure regulating cylinders 3 improves the adaptability of the equipment, enabling it to simultaneously handle materials or processes of different sizes and pressure requirements, meeting diverse production needs. For complex production environments, it can switch between single squeeze roller group operating mode and multi-squeeze roller group operating mode at any time, adjusting the roller pressure according to different process flows, increasing the flexibility of the equipment.

[0028] A remote regulating valve assembly 7 is also provided for adjusting the pressure of the pressure regulating cylinder 3, allowing operators to conveniently adjust the pressure of the pressure regulating cylinder 3 from a distance from the equipment. This not only improves operational safety but also simplifies the pressure regulation process in the production environment, avoids frequent manual adjustments near the equipment, and improves work efficiency.

[0029] The remote regulating valve group 7 includes a first regulating valve 71 and a second regulating valve 72, which respectively control the first pressure regulating cylinder 31 and the second pressure regulating cylinder 32 to achieve independent pressure regulation of the squeeze rollers at both ends. Operators can precisely adjust the pressure of each cylinder according to actual needs, thereby optimizing roller pressure control, ensuring uniform pressure at both ends that meets process requirements, and improving product quality.

[0030] Both the first regulating valve 71 and the second regulating valve 72 are equipped with a pressure reducing valve 711, a throttle valve 712, and a start switch 713. The pressure reducing valve 711 precisely controls the output pressure of the regulating valves, ensuring that both valves operate within the set pressure range, thereby stabilizing the cylinder pressure and preventing overpressure or underpressure, ensuring stable and safe operation of the equipment. The throttle valve 712 regulates the airflow, thus precisely controlling the cylinders and making the production process more flexible and adjustable, especially important for processes with high production speed or drying requirements. The independent start switch 713 allows for precise control of each cylinder, facilitating fine-tuning operations.

[0031] In actual production, the strip passes through the cooling device and enters the dry roller device through the lower inlet. At this time, there are still various liquid residues on the surface of the strip. The operator adjusts the actual position of the fixed squeezing roller 211 by adjusting the adjustable positioning screw 11 to reduce the deviation problem caused by the squeezing roller not being on the center line of the strip. Then, the movable squeezing roller 212 is remotely pressure regulated by the pressure reducing valve 711 and the throttle valve 712 to remotely set the pressure for thin and thick strips. For strips with extremely poor shape or cracks, the pressure can be selected. There are also two working modes, which can be switched between the single squeezing roller group working mode and the multi-squeezing roller group working mode at any time, which can fully meet the liquid squeezing problem of various strip production lines.

[0032] By adopting the above technical solution, the adjustable pressure vertical dry roller device of this utility model, through the structural cooperation of the squeeze roller group 2, the pressure regulating cylinder 3, and the remote regulating valve, achieves precise control of the squeeze roller pressure, provides flexible pressure adjustment and remote control, and ensures stable operation of the equipment under different working conditions. A maintenance window 6 is also provided, simplifying maintenance operations and reducing equipment downtime. Furthermore, by adjusting the scale measuring ruler 5 and applying the pressure reducing valve 711 and throttle valve 712, the accuracy and energy efficiency of the equipment are improved, while the mechanical structure is optimized, enhancing the stability and service life of the equipment. It is suitable for various production environments and has high efficiency and energy-saving effects.

[0033] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
