Description

Technical Field

[0001] This utility model relates to the field of lubrication devices, and more specifically, to a lubricating oil cooling device and a lubrication system. Background Technology

[0002] Composite filter rod forming machines are among the best-selling composite filter rod forming machines globally and represent a mainstream new type of composite filter rod forming machine. The lubrication system of this equipment uses an air cooling device to cool the lubricating oil. However, in actual use, the air cooling device has proven ineffective in cooling the lubricating oil, causing it to operate at a high temperature (around 80 degrees Celsius). This significantly shortens the lubricating oil's lifespan, accelerates wear on machine parts, reduces equipment lifespan, makes machine parts prone to deformation and aging, increases the failure rate, and reduces operating efficiency. To maintain normal equipment operation, frequent lubricating oil changes are necessary, thus increasing operating costs and energy consumption. Utility Model Content

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0031] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0032] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0033] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0034] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0035] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0036] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a lubricating oil cooling device according to this embodiment includes a main lubricating oil cooler, an oil filter, an oil inlet pipe, an oil outlet pipe, a cooling water inlet pipe, a cooling water return pipe, an automatic oil temperature control device, and a mounting base for the main lubricating oil cooler. This lubricating oil cooling device is installed at the rear of the equipment, located between the equipment's oil tank and the lubrication system of the transmission mechanism.

[0037] The lubricating oil from the oil tank of the composite filter rod forming machine is transported to the main lubricating oil cooler through the oil filter and oil inlet pipe. It then enters the first sealed oil chamber through the oil inlet, and subsequently enters the first U-shaped copper tube assembly for initial cooling. After cooling by the first U-shaped copper tube assembly, the lubricating oil passes through the second sealed oil chamber and enters the second U-shaped copper tube assembly for a second cooling process. The lubricating oil after the second cooling passes through the third sealed oil chamber and enters the oil outlet pipe, which then supplies the lubrication system of the composite filter rod forming machine's transmission mechanism. Both the first and second U-shaped copper tube assemblies are placed in the cooling water circulation sealed chamber of the main lubricating oil cooler. A centralized cooling water heat exchanger supplies cooling water through the cooling water inlet pipe into the water-sealed chamber of the main lubricating oil cooler. After completing the cooling function, the water is returned to the centralized cooling water heat exchanger through the cooling water return pipe, thus continuously cooling the lubricating oil. The automatic oil temperature control device is installed on the cooling water inlet pipe. By controlling the cooling water flow, the lubricating oil temperature is regulated and kept at a suitable temperature (around 50 degrees Celsius). This solves the technical problem that the lubricating oil system of the composite filter rod machine operates at a high temperature (around 80 degrees Celsius) due to the unsatisfactory cooling effect of the air cooling device.

[0038] Based on the same inventive concept, this embodiment also provides a lubrication system. Since the working principle of the lubrication system in this embodiment is the same as that of the above-mentioned lubricating oil cooling device, the repetition will not be repeated.

[0039] The lubrication system of this embodiment includes a main lubricating oil cooler 1, an oil tank 11, a centralized cooling water heat exchanger 4, and a transmission mechanism lubrication system 7. The main lubricating oil cooler 1 is connected to the oil tank 11, the centralized cooling water heat exchanger 4, and the transmission mechanism lubrication system 7. The main lubricating oil cooler 1 has an oil chamber 34 and a cooling water chamber 32 for heat exchange. Lubricating oil and cooling water can flow into the oil chamber 34 and the cooling water chamber 32 respectively, thereby achieving heat exchange between the lubricating oil and the cooling water. Compared with air cooling, this significantly improves the cooling effect on the lubricating oil. Furthermore, a lubricating oil recovery and circulation system (which can be a pipeline assembly) is provided between the transmission mechanism lubrication system 7 and the oil tank 11 to achieve the recycling of the lubricating oil.

[0040] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
