Description

Technical Field

[0001] This utility model relates to the field of industrial cooling equipment technology, specifically to an adjustable cigarette machine cooling system. Background Technology

[0002] Currently, the lubricating oil circulation system of cigarette rolling machines generally adopts a fixed cooling structure, mainly consisting of a single-layer cooling pipeline and static heat dissipation components. This system suffers from slow response, coarse control, and low heat dissipation efficiency when facing cooling demands under different production speeds and load conditions. According to the "Research Report on Thermal Management of Cigarette Rolling Equipment" (China Tobacco Machinery Technology Center, 2019), after six hours of high-speed operation, the lubricating oil temperature of a cigarette rolling machine can rise to 65℃-70℃. This significantly accelerates the aging of rubber seals, leading to decreased lubrication and increased equipment wear. In particular, critical transmission components such as the SE main drive box and the Max gear transmission box are extremely sensitive to temperature changes, urgently requiring flexible and efficient cooling control strategies. Utility Model Content

[0003] To address the aforementioned shortcomings or defects in existing technologies, an adjustable cigarette machine cooling system with modular structure and dynamically adjustable cooling intensity is provided. This system can flexibly adjust the cooling path and cooling intensity according to different production conditions (such as high speed, low speed, or intermittent operation), and implement differentiated cooling strategies for different lubrication points, thereby effectively extending the service life of lubricating oil and equipment components and improving the reliability of system operation.

[0004] To achieve the above objectives, this utility model provides an adjustable cigarette machine cooling system, including a compressor, multiple cooling modules, a throttling device, and a proportional flow divider valve;

[0005] The refrigerant outlet of the cigarette machine is connected to the compressor, the compressor outlet is connected to the cooling module, multiple cooling modules are connected in series, the outlet of the cooling module is connected to the throttling device to control the flow, the outlet of the throttling device is connected to the proportional flow divider valve, and the two outlets of the proportional flow divider valve are respectively connected to the refrigerant inlet of the SE main drive box and the Max gear drive box.

[0006] The cooling module includes a bracket, a heat sink mounted on the bracket, and a fan disposed on one side of the heat sink. The heat sink includes S-shaped, meandering cooling pipes and heat sink fins mounted on the cooling pipes.

[0007] In some embodiments, the cooling system further includes a frame. The cooling modules are arranged in two groups, each fixed to the frame by its respective support; the two cooling modules are divided into a front cooling module and a rear cooling module according to the refrigerant flow direction.

[0008] In some implementations, the compressor outlet connection is connected to the aftercooling module inlet via an inlet bypass pipe, on which a control valve is installed.

[0009] In some implementations, the outlet of the pre-cooling module is connected to a bypass pipe throttling device, and a control valve is installed on the bypass pipe.

[0010] In some embodiments, temperature sensors are respectively installed at the coolant outlets of the SE main drive box and the Max gear drive box.

[0011] The proportional flow divider valve adjusts the refrigerant flow distribution ratio at the two outlets based on feedback signals from temperature sensors in the SE main drive box and the Max gear drive box.

[0012] In some embodiments, the proportional flow divider valve is an electrically controlled valve.

[0013] In some embodiments, the drive motor of the fan is a speed-regulating motor.

[0014] In some embodiments, two parallel root cooling pipes are arranged side by side on the heat sink, with a spacing of 50-80 mm between the cooling pipes.

[0015] An adjustable cigarette machine cooling system applying the above-mentioned technical solution of this utility model has the following effects:

[0016] Flexible adjustment of cooling intensity: By combining the throttling device and the proportional flow divider valve, the coolant distribution ratio between the total system flow and the SE main drive box and the Max gear drive box can be adjusted separately, thereby accurately matching the cooling requirements of each component and improving temperature control efficiency.

[0017] Achieving precise zoned cooling: Combining temperature sensors and a proportional flow control mechanism, the system can automatically adjust the coolant distribution based on real-time temperature feedback from each transmission box, meeting the differentiated cooling needs of different lubrication zones.

[0018] Easy module addition, removal, and replacement: The cooling module adopts an independent structural design and is fixed to the rack by a bracket, supporting modular assembly and disassembly. When repairing or replacing a module, it can be temporarily bypassed through bypass pipelines and control valves, avoiding system downtime and improving operation and maintenance efficiency.

[0019] In summary, this utility model has good cooling regulation capability, structural adaptability and maintenance convenience, and is particularly suitable for the lubrication system of cigarette machines in high-speed and high-load operating environments. Attached Figure Description

[0025] The specific embodiments of this utility model are described in detail below. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0026] In this utility model, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the orientation in the assembled and used state. "Inner" and "outer" refer to the inner and outer sides relative to the outline of each component itself.

[0027] This utility model provides an adjustable cigarette machine cooling system, such as... Figure 1 and Figure 2 The system includes a compressor 1, multiple cooling modules, a throttling device 5, and a proportional flow divider valve.

[0028] The refrigerant outlet of the cigarette machine is connected to compressor 1, the outlet of compressor 1 is connected to a cooling module, multiple cooling modules are connected in series, the outlet of the cooling module is connected to a throttling device 5 to control the flow rate, the outlet of the throttling device 5 is connected to a proportional flow divider valve, and the two outlets of the proportional flow divider valve are respectively connected to the refrigerant inlets of the SE main drive box and the Max gear drive box.

[0029] The cooling module includes a bracket, a heat sink mounted on the bracket, and a fan 3 disposed on one side of the heat sink. The heat sink includes S-shaped, meandering cooling pipes 2 and heat sink fins 4 mounted on the cooling pipes 2.

[0030] This modular cooling system features dynamically adjustable cooling capacity, making it particularly suitable for the lubricating oil cooling needs of cigarette machines under varying production rhythms and ambient temperatures. The system uses compressor 1 to increase refrigerant pressure, which then flows sequentially through multiple cooling modules connected in series. Fans 3 and heat dissipation structures within these modules effectively cool the refrigerant. After the flow rate and pressure are reduced by a throttling device 5, a proportional distribution valve distributes the refrigerant as needed to the lubrication systems of the SE main drive box and the Max gear drive box. The system also incorporates temperature sensors for dynamic monitoring of oil temperature and adjusts cooling capacity distribution based on feedback. Furthermore, by inlet and outlet bypass pipes and control valves, flexible module-level switching and hot-swappable maintenance are possible, ensuring continuous system operation while also balancing energy conservation and equipment management.

[0031] Compressor 1 is used to increase the refrigerant pressure and is the power source in the refrigeration cycle. Compressor 1 draws in low-pressure refrigerant from the cigarette machine, compresses it, and then sends it to the cooling module for cooling. A screw-type refrigeration compressor 1 is commonly used, characterized by high efficiency and stable operation.

[0032] like Figure 3 As shown, this system employs two cooling modules arranged in series. Each cooling module consists of a heat sink, a fan 3, and a mounting bracket. The heat sink contains S-shaped, meandering cooling pipes 2, through which the refrigerant exchanges heat with the outside air. Aluminum or copper heat sink fins 4 are welded to the outside of the cooling pipes 2 to improve heat exchange efficiency. The fan 3 is located on one side of the heat sink, driving airflow to enhance the heat dissipation process. The fan 3 uses a speed-regulating motor, allowing for flexible speed adjustment according to changes in heat load, balancing cooling efficiency and energy consumption. The heat sink includes two parallel and spaced-apart cooling pipes 2, with a spacing of 50-80mm between them.

[0033] The two cooling modules are fixed to the frame by their respective brackets, resulting in a stable structure that facilitates layout and maintenance. The vertical arrangement saves space, while the front-to-back sequence allows for sequential refrigerant flow and control.

[0034] A bypass pipe is installed at the outlet of compressor 1, connecting to the inlet of the rear cooling module. Another bypass pipe connects to the outlet of the front cooling module and then to the throttling device 5. Each bypass pipe is equipped with an electrically controlled valve (such as a ball valve or proportional control valve) to switch the cooling path during system operation. When a cooling module needs to be replaced or repaired, the corresponding bypass pipe can be opened to achieve "hot-swap" of the module without interrupting system operation. Simultaneously, under low-load conditions, only one cooling module is activated to reduce power consumption and improve operating economy.

[0035] The refrigerant after the cooling module enters the throttling device 5, which regulates the flow rate and reduces the pressure to meet cooling requirements. The throttling device 5 can be an electronic expansion valve or a capillary tube structure, and its opening degree can be adjusted in real time according to temperature requirements.

[0036] The proportional distribution valve is used to distribute refrigerant as needed to the SE main drivebox and the Max gearbox. This valve is an electronically controlled proportional valve that intelligently adjusts based on temperature sensor signals from each lubrication tank to ensure that the oil temperature in each part is maintained within the set range, thereby improving the accuracy and response speed of the system cooling.

[0037] Temperature sensors are installed at the lubricating oil outlets of the SE main drivebox and the Max gearbox to monitor real-time oil temperature data. The sensors can be digital thermocouples or PT100 platinum resistance thermometers, featuring high sensitivity, fast response, and strong anti-interference capabilities.

[0038] The technical advantages of this utility model are:

[0039] The cooling power is adjustable and controllable. Through the dual regulation mechanism of the throttling device 5 and the proportional flow divider valve, the system can control the total cooling power and precisely allocate cooling resources to different lubrication points, significantly improving cooling efficiency and system response sensitivity, avoiding overcooling or undercooling, and ensuring stable operation of the equipment for a long time.

[0040] Maintenance and repair are simple, and hot-swappable cooling modules are supported. It employs two sets of series-connected cooling modules, and is equipped with electrically controlled valves for the inlet and outlet bypass pipes. This allows for flexible selection of one or two sets of cooling modules based on load conditions, achieving a balance between high efficiency and energy saving. Furthermore, individual cooling modules can be replaced while the equipment is running, improving maintenance convenience and production continuity.

[0041] The modular design facilitates maintenance. The cooling module adopts a standardized structure, consisting of a bracket, heat sink, and fan. The structure is compact and clearly laid out, making it easy to replace and expand. The vertical arrangement saves space and adapts to various cigarette machine installation environments.

Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0043] It should also be noted that the various specific technical features described in the above embodiments can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0044] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
