Description

Technical Field

[0001] This utility model relates to the field of tobacco packaging technology, and in particular to a hydraulic oil cooling system and a tobacco packaging box machine. Background Technology

[0002] The re-drying production line for threshed tobacco leaves is a crucial step in tobacco processing. It primarily performs secondary processing on initially dried tobacco leaves to improve their quality, uniformity, and industrial usability. It is mainly used for the initial raw material processing in cigarette factories or for the production of export-grade tobacco sheets. The re-drying production line utilizes multiple tobacco packaging machines. Their main function is to pack the tobacco sheets into specific iron tobacco frames and then send them to the next stage of equipment for further processing.

[0003] During this process, the cigarette packaging machine needs to perform multiple flipping actions via the hydraulic system to complete the packaging. Because the original cigarette packaging machine in the current technology uses a fan to cool the hydraulic oil, and this machine operates frequently, the fan's cooling effect on the hydraulic oil is ineffective. After a period of use, the hydraulic oil temperature exceeds the normal operating range, and the cigarette packaging machine can no longer perform the normal flipping action, severely affecting normal production efficiency.

[0004] Therefore, a hydraulic oil cooling system and a cigarette packaging machine are needed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a hydraulic oil cooling system and a cigarette packaging machine that can effectively cool the hydraulic oil, thereby ensuring the production efficiency of the cigarette packaging machine.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] The hydraulic oil cooling system includes:

[0008] A water storage tank, which is connected to an external water source, is used to store cooling water;

[0009] A hydraulic oil heat exchanger is used to cool hydraulic oil. The hydraulic oil heat exchanger is connected to the water tank and is positioned at a lower position relative to the water tank.

[0010] A buffer water tank is connected to the outlet end of the hydraulic oil heat exchanger, and the buffer water tank is positioned at a lower position relative to the hydraulic oil heat exchanger.

[0011] The cooling tower has its upper end connected to the buffer water tank via a water pipe, and its lower end connected to the water storage tank. The cooling tower is positioned higher than the water storage tank, and a water pump is installed on the water pipe.

[0012] In some embodiments, the water storage tank is provided with a first switch control valve that is connected to an external water source.

[0013] In some embodiments, a water level monitor is provided in the water storage tank, and the water level monitor is electrically connected to the first switch control valve.

[0014] In some embodiments, the hydraulic oil heat exchanger is provided with a hydraulic oil inlet pipe and a hydraulic oil outlet pipe.

[0015] In some embodiments, the buffer tank is equipped with a low water level switch and a high water level switch, both of which are electrically connected to the water pump.

[0016] In some embodiments, a second switch control valve is provided on the connecting pipeline between the water storage tank and the hydraulic oil heat exchanger.

[0017] In some embodiments, a plurality of heat dissipation fins are provided at intervals along the height direction of the cooling tower.

[0018] In some embodiments, a cooling fan is provided at the upper end of the cooling tower, and the cooling fan is used to blow air into the cooling tower.

[0019] In some embodiments, the water pump is electrically connected to the cooling fan, and the water pump and the cooling tower can be turned on or off synchronously.

[0020] The cigarette packaging machine includes a hydraulic system and a hydraulic oil cooling system as described above, wherein the hydraulic system is connected to the hydraulic oil heat exchanger of the hydraulic oil cooling system.

[0021] The beneficial effects of this utility model are:

[0022] This utility model provides a hydraulic oil cooling system. A water storage tank is connected to an external water source to store cooling water. A hydraulic oil heat exchanger cools the hydraulic oil and is connected to the water storage tank, positioned lower than the tank. A buffer tank is connected to the outlet of the hydraulic oil heat exchanger and is also positioned lower. The upper end of a cooling tower is connected to the buffer tank via a water pipe, and the lower end is connected to the water storage tank. The cooling tower is positioned higher than the tank, and a water pump is installed on the water pipe. Because the height of the cooling tower, water storage tank, hydraulic oil heat exchanger, and buffer tank decreases sequentially, cooling water can automatically flow through these components in sequence under gravity. This process utilizes gravity directly to achieve cooling water circulation, thereby reducing energy consumption. By exchanging heat in a hydraulic oil heat exchanger, the temperature of the hydraulic oil can be significantly reduced, effectively cooling it and ensuring the production efficiency of the cigarette packaging machine. The cooled water, having completed heat exchange, enters a buffer tank and is then pumped to the top of a cooling tower. As the cooling water flows downwards within the tower, it simultaneously dissipates heat, lowering its temperature. Under gravity, it then recirculates into a storage tank. This closed-loop cooling water circulation system reduces cooling water consumption.

[0023] The present invention provides a cigarette packaging machine, which includes a hydraulic system and a hydraulic oil cooling system as described above, which can effectively cool the hydraulic oil, thereby ensuring the production and operation efficiency of the cigarette packaging machine.

[0028] Before explaining any implementation of this application in detail, it should be understood that this application is not limited to its application to the structural details and component arrangements set forth in the following description or shown in the above drawings.

[0029] In this application, the terms "comprising," "including," "having," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0030] In this application, the terms "connection," "combination," "coupling," and "installation" can refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without the need for an intermediary, while an indirect connection refers to two parts or components each being connected to at least one intermediary, with the connection achieved through the intermediary. Furthermore, "connection" and "coupling" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.

[0031] In this application, those skilled in the art will understand that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0032] In this application, the directional terms "upper," "lower," "left," "right," "front," and "rear" are used to describe the orientation and positional relationships shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when an element is mentioned as being connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected through an intermediate element. It should also be understood that directional terms such as upper side, lower side, left side, right side, front side, and rear side not only represent positive orientation but can also be understood as lateral orientation. For example, "below" can include directly below, lower left, lower right, lower front, and lower rear.

[0033] During the operation of a cigarette packaging machine, if the hydraulic oil temperature exceeds the normal operating range, the machine cannot perform its normal tilting action, severely impacting production efficiency. To solve this problem, effective cooling of the hydraulic oil is necessary to ensure the machine's production efficiency. For example... Figure 1 As shown, this utility model provides a hydraulic oil cooling system. The hydraulic oil cooling system includes a water storage tank 1, a hydraulic oil heat exchanger 2, a buffer water tank 3, and a cooling tower 5.

[0034] The cooling tower 5 is connected to an external water source and is used to store cooling water. The hydraulic oil heat exchanger 2 is used to cool the hydraulic oil and is connected to the water storage tank 1, with the heat exchanger positioned lower than the tank. The buffer tank 3 is connected to the outlet of the hydraulic oil heat exchanger 2 and is also positioned lower than the heat exchanger. The upper end of the cooling tower 5 is connected to the buffer tank 3 via a water pipe 4, and the lower end is connected to the water storage tank 1. The cooling tower 5 is positioned higher than the tank, and a water pump 41 is installed on the water pipe 4.

[0035] Because the cooling tower 5, water storage tank 1, hydraulic oil heat exchanger 2, and buffer water tank 3 are positioned at progressively lower heights, the cooling water can automatically flow through these components sequentially under gravity. This process utilizes gravity directly to achieve cooling water circulation, thereby reducing energy consumption. Heat exchange in the hydraulic oil heat exchanger 2 effectively lowers the temperature of the hydraulic oil, ensuring efficient operation of the cigarette packaging machine. The cooled water, having undergone heat exchange, enters the buffer water tank 3 and is then pumped to the top of the cooling tower 5 by pump 41. As the cooling water flows downwards within the cooling tower 5, it simultaneously dissipates heat, lowering its temperature. Under gravity, it then recirculates back into the water storage tank 1. This closed-loop cooling water circulation system reduces cooling water consumption.

[0036] In some embodiments, the water storage tank 1 is equipped with a first switch control valve that connects to an external water source. By providing this first switch control valve, when water replenishment is needed, opening the valve allows external water to be used to replenish the water storage tank 1, ensuring sufficient water flow into the hydraulic oil heat exchanger 2 and effectively cooling the hydraulic oil. When the water storage tank 1 is full, simply closing the first switch control valve prevents cooling water from overflowing and reduces water waste.

[0037] In some embodiments, a water level monitor is installed in the water storage tank 1, and the water level monitor is electrically connected to the first switch control valve. By installing the water level monitor, the water level in the water storage tank 1 can be detected in real time, thereby enabling timely determination of whether the water level in the water storage tank 1 is sufficient. When the water level is insufficient, the water level monitor controls the first switch control valve to open, thereby allowing water from an external water source to quickly replenish the water storage tank 1, ensuring sufficient cooling water circulation in the hydraulic oil cooling system. Specifically, the water level monitor can be controlled by a controller or by directly sending an electrical signal to the first switch control valve. The controller can be a microcontroller or a PLC, and no further restrictions are imposed here. The control principles of the water level monitor and the first switch control valve are existing technologies and will not be elaborated upon here.

[0038] In some embodiments, the hydraulic oil heat exchanger 2 is provided with a hydraulic oil inlet pipe 21 and a hydraulic oil outlet pipe 22. This arrangement facilitates the connection of the hydraulic oil heat exchanger 2 with the hydraulic system, thereby enabling effective cooling of the hydraulic oil in the hydraulic system.

[0039] In some embodiments, the buffer tank 3 is equipped with a low-level switch 32 and a high-level switch 31, both of which are electrically connected to the water pump 41. The low-level switch 32 detects the lowest liquid level in the buffer tank 3, and the high-level switch 31 detects the highest liquid level in the buffer tank 3. When the low-level switch 32 detects that the liquid level in the buffer tank 3 is low, the amount of cooling water in the buffer tank 3 is insufficient, and the low-level switch 32 controls the water pump 41 to stop working, preventing the water pump 41 from running dry and thus reducing energy consumption. When the high-level switch 31 detects that the liquid level in the buffer tank 3 is high, the amount of cooling water in the buffer tank 3 is sufficient, and the high-level switch 31 controls the water pump 41 to start working, preventing the cooling water in the buffer tank 3 from overflowing and thus reducing cooling water consumption. The principle of using high-level switch 31 and low-level switch 32 to control water pump 41 is existing technology, and its control principle will not be elaborated on here.

[0040] In some embodiments, a second on / off control valve 61 is provided on the connecting pipeline 6 between the water tank 1 and the hydraulic oil heat exchanger 2. By providing the second on / off control valve 61, when the hydraulic system is working, the second on / off control valve 61 is opened synchronously, allowing cooling water to flow smoothly into the hydraulic oil heat exchanger 2, thereby exchanging heat with the higher-temperature hydraulic oil. In this embodiment, a serpentine water channel can be arranged in the hydraulic oil heat exchanger 2 to slow down the flow rate of the cooling water, increase the heat exchange area, and ensure effective cooling of the hydraulic oil.

[0041] In some embodiments, multiple heat dissipation fins are arranged at intervals along the height of the cooling tower 5. By providing multiple heat dissipation fins, the contact area with the cooling water can be increased, thereby efficiently cooling the high-temperature cooling water after heat exchange, facilitating subsequent recycling.

[0042] In some embodiments, a cooling fan is provided at the top of the cooling tower 5 to blow air into the cooling tower 5. By providing a cooling fan, air circulation can be accelerated, thereby quickly dissipating the heat from the high-temperature cooling water and ensuring the cooling effect.

[0043] In some embodiments, the water pump 41 is electrically connected to the cooling fan, and the water pump 41 and the cooling tower 5 can be turned on or off synchronously. When the water pump 41 starts, high-temperature cooling water enters the cooling tower 5, and the cooling fan works synchronously during this process, effectively reducing the temperature of the cooling water. When the water pump 41 stops working, the cooling fan stops working synchronously, reducing energy consumption.

[0044] This embodiment also provides a cigarette packaging machine, including a hydraulic system and the hydraulic oil cooling system as described above. The hydraulic system is connected to the hydraulic oil heat exchanger 2 of the hydraulic oil cooling system, which can effectively cool the hydraulic oil, thereby ensuring the production and operation efficiency of the cigarette packaging machine.

[0045] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
