Description

Technical Field

[0002] As one of the core equipment in the modern tobacco industry, the efficient and precise operation of high-speed cigarette making machines is crucial to ensure the quality and output of cigarette products. Through a series of precise mechanical structures and control systems, high-speed cigarette making machines realize the automated process from tobacco supply, rolling and forming to cutting and packaging. In high-speed cigarette making machines, the smooth operation of mechanical transmission parts (such as gears, bearings, chains, etc.) depends on effective lubrication. As the cigarette making machine runs at high speed, a large amount of heat will be generated in the mechanical transmission part, which will be transferred to the lubricating oil, causing the oil temperature to gradually increase. As a key component of the cigarette making machine, the precision of the internal mechanical structure of the cigarette gun is extremely high. Excessive oil temperature will not only affect the lubrication effect inside the cigarette gun, but may also cause problems such as seal failure and bearing damage, which will directly affect the molding quality of the cigarette and the service life of the cigarette gun.

[0003] During the operation of the high-speed packaging machine, the lubricating oil in the internal mechanical transmission part will become higher and higher as the operating oil temperature of the equipment increases.

[0031] The present invention proposes an embodiment of a high-speed wrapping unit 12 cooling and waste heat utilization system. Specifically, Figure 1 As shown, it includes: a centralized cold water tank 2, the centralized cold water tank 2 is fixedly connected to a cold water main pipe 7, the cold water main pipe 7 is fixedly connected to a group of water supply branches 27, and each water supply branch 27 is respectively installed with a circulating pump 9; each water supply branch 27 is respectively fixedly connected to the water inlet of the internal cooling pipe of the high-speed wrapping unit 12, and the water outlet of the internal cooling pipe of each high-speed wrapping unit 12 is respectively fixedly connected to the return water branch 13, and each return water branch 13 is respectively fixedly connected to the heat exchanger 15; each heat exchanger 15 is respectively fixedly connected to the branch pipe 16, and each branch pipe 16 is respectively fixedly connected to the return water pipe 17, and the return water pipe 17 is fixedly connected to the centralized cold water tank 2.

[0032] It should be noted that the cooling water starts from the centralized cold water tank 2 and enters each water supply branch 27 through the cold water main pipe 7; driven by the circulating pump 9, the cooling water flows into the internal cooling pipe of the high-speed wrapping unit 12 to absorb the heat generated during the operation of the equipment; the heated cooling water enters the heat exchanger 15 through the return water branch 13 to exchange heat with the cold fluid to reduce the temperature; the cooled water returns to the centralized cold water tank 2 again through the branch pipe 16 and the return water pipe 17 to prepare for the next round of circulation.

[0033] In the embodiment of the present invention, the top of the centralized cold water tank 2 is fixedly connected to the water supply pipe 1. The water supply pipe 1 is a pipe connecting an external water source (such as tap water, well water, cooling tower water, etc.) and the centralized cold water tank 2. The centralized cold water tank 2 and the water supply pipe 1 are connected by flange connection, threaded connection, welding or other connection methods with good sealing properties to ensure that the connection does not leak.

[0034] In the embodiment of the present invention, the high-speed wrapping unit cooling and waste heat utilization system further includes a controller 8, and the heat exchanger 15 and the circulating pump 9 are electrically connected to the controller 8. The controller 8 communicates and controls the heat exchanger 15 and the circulating pump 9 through electrical connection, monitors the working state of the system using data collected by sensors, and issues control instructions according to preset algorithms and logics to adjust the working states of the heat exchanger 15 and the circulating pump 9.

[0035] In the embodiment of the present invention, a filter valve 24 and a manual switch valve 25 are installed on the return pipe 17. By setting the filter valve 24, filtering of the return water is achieved, and by setting the manual switch valve 25, manual closing of the system is achieved.

[0036] In the embodiment of the present invention, a switch valve 4, a flow meter 5 and a pressure gauge 6 are installed on the cold water main pipe 7, and the switch valve 4, the flow meter 5 and the pressure gauge 6 are electrically connected to the controller 8 respectively; the controller 8 is wirelessly connected to the upper unit, and the upper unit includes a computer, a PC, a mobile phone group, an LED and other mobile display terminals, so as to realize digital display of information on the mobile display terminal, and realize cooling control of the high-speed wrapping unit through the mobile display terminal. By setting the switch valve 4, the automatic switch of the cooling system can be controlled, and by setting the flow meter 5, the flow rate and velocity in the cold water main pipe 7 can be displayed in real time, and the pressure gauge 6 displays the water pressure in the cold water main pipe 7.

[0037] In the embodiment of the present invention, each water supply branch 27 is respectively installed with a regulating control valve 10 and a pressure gauge 11, and the regulating control valve 10 and the pressure gauge 11 are respectively electrically connected to the controller 8. The supply amount of cold water is determined by controlling the opening size of the regulating control valve 10. The pressure gauge 11 is provided to realize the pressure detection of the water supply branch.

[0038] In the embodiment of the present invention, each return water branch 13 is respectively installed with a return water temperature sensor 14, and the return water temperature sensor 14 is electrically connected to the controller 8. The return water temperature sensor 14 collects temperature and transmits it to the controller 8, and the controller 8 controls the opening size of the regulating control valve 10 according to the water temperature.

[0039] In the embodiment of the present invention, the centralized cold water tank 2 is connected to a liquid level sensor 3, which is electrically connected to a controller 8. When the liquid level sensor 3 detects that the water level in the centralized cold water tank 2 is low, the centralized cold water tank 2 is supplemented with fresh cold water through the water supply pipe 1.

[0040] In the embodiment of the present invention, the centralized cold water tank 2 is connected to a cold water temperature sensor 26, which is electrically connected to the controller 8. When the cold water temperature sensor 26 detects that the temperature of the centralized cold water tank 2 is high, fresh cold water is added to the centralized cold water tank 2 through the water supply pipe 1 to cool it down.

[0041] The workflow of the embodiment of the present invention is as follows:

[0042] The high-speed wrapping unit cooling and waste heat utilization system of the embodiment of the present invention uses cold water to cool the high-speed wrapping unit 12, and the centralized cold water is used for cooling. When the high-speed wrapping unit 12 is working, the circulation pump 9 is turned on, so that the cold water in the centralized cold water tank 2 enters the cooling pipe in the high-speed wrapping unit 12 through the cold water main pipe 7 and the water supply branch 27, and then enters the centralized cold water tank 2 through the return branch 13, the heat exchanger 15, the branch pipe 16, and the return pipe 17. The water temperature of each branch corresponding to the high-speed wrapping unit 12 is different. The cold water after absorbing heat is respectively collected by the corresponding return water temperature sensor 14 and transmitted to the controller 8. The controller 8 controls the opening size of the regulating control valve 10 according to the water temperature, thereby determining the supply of cold water, and returns to the centralized cold water tank 2 through the return pipe 17 after cooling through the heat exchanger 15. Through precise temperature monitoring and flow regulation, the system can ensure that the high-speed wrapping unit can be fully cooled under different working conditions to avoid performance degradation or damage caused by overheating of the unit. The waste heat recovery mechanism allows cooling water to be reused after releasing heat, reducing the consumption of new water and energy waste. The system can respond to the cooling needs of high-speed packaging units in real time, and maintain the stability of the unit's operating status by dynamically adjusting the flow and temperature of cooling water, thereby improving production efficiency and product quality.

[0043] In one embodiment of the present invention, the return pipe 17 is fixedly connected to the heating water inlet pipe 19, the heating water inlet pipe 19 is fixedly connected to the radiator group 21, the radiator group 21 is fixedly connected to the heating water return pipe 22, the heating water return pipe 22 is fixedly connected to the return pipe 17, at least one of the heating water inlet pipe 19 or the heating water return pipe 22 is installed with a heating valve 23, the heating water inlet pipe 19 is installed with a heating regulating control valve 20, and the return pipe 17 is installed with a switch valve 18 corresponding to the heating water return pipe 22 and the heating water inlet pipe 19. Among them, by adjusting the opening of the heating valve 23, the amount of water entering the radiator group 21 can be adjusted, thereby affecting the heating effect. The heating regulating control valve 20 is used to more accurately adjust the water flow and temperature entering the radiator group to meet different heating needs. It should be noted that hot water enters the radiator group 21 through the heating water inlet pipe 19, and the hot water releases heat to the indoor air in the radiator group 21, and its own temperature decreases. The cooled water flows back to the return pipe 17 through the heating return pipe 22. After the cooled water is collected in the return pipe 17, it is sent to the heating source again for heating. The heated water enters the radiator group 21 again through the heating water inlet pipe 19, and the cycle repeats.

[0044] In winter, the switch valve 18 is closed and the heating valve 23 is opened, so that the water in the return pipe 17 enters the return pipe 17 through the heating water inlet pipe 19, the radiator group 21, and the heating return pipe 22. The radiator group 21 dissipates heat to reduce the return water temperature again, which is convenient for subsequent cooling. The controller 8 controls the opening size of the heating regulating control valve 20 to adjust the heating temperature. By accurately controlling the opening size of the heating regulating control valve 20, the heating intensity can be adjusted according to actual needs, energy waste can be avoided, and the heating efficiency can be improved. Closing the switch valve 18 ensures the closedness of the heating system, reduces the impact of external factors (such as non-heating water) on the system, and improves the stability and reliability of the system. This control process not only realizes the effective operation of the heating system, but also improves the heating efficiency, comfort and energy saving through intelligent control.

[0045] The above describes in detail the structure, features and effects of the present invention based on the embodiments shown in the drawings, but the above is only a preferred embodiment of the present invention. It should be noted that the technical features involved in the above embodiments and their preferred methods can be reasonably combined and matched into a variety of equivalent schemes by those skilled in the art without departing from or changing the design ideas and technical effects of the present invention; therefore, the present invention is not limited to the scope of implementation shown in the drawings, and all changes made in accordance with the concept of the present invention, or modifications to equivalent embodiments with equivalent changes, which still do not exceed the spirit covered by the specification and drawings, should be within the protection scope of the present invention.
