Description

[0002] In the process of tobacco processing and making tobacco shreds, tobacco stems are used as fillers in cigarettes to reduce the tar content of cigarettes and improve the smoking performance of cigarettes. In order to improve the quality of the stems cut by the stem cutter, the purity and softness of the incoming tobacco stems must be improved. Generally, there are several methods: screening of large and small stems, impurity removal, washing of stems, heating and humidification, or pressing of stems.

[0003] Among them, after the stems are washed, it is required to remove excess surface water. Excessive surface water will cause temperature and humidity to increase and absorb moisture too quickly and excessively after storage, affecting subsequent processing; the stem pressing process uses a hot pressing and cold cutting process. Too high a temperature is not conducive to the stem cutter cutting loose stems. Due to high temperature and high humidity, the stems will stick together in flaky shapes or have more stem heads, affecting the quality of the cut stems, production costs and production efficiency. Therefore, it is particularly important to ensure the qualified rate of the temperature and humidity of the tobacco stems during the processing of the tobacco stems.

[0030] like Figure 1 , Figure 2 As shown, an embodiment of the present application provides a cooling and dehumidifying device for a tobacco stem conveying equipment, including a gas input module, a control module 20 and a gas output module. The gas output module is arranged above the conveying equipment to purge the tobacco stems on the conveying equipment. The control module 20 is connected to the gas input module signal to control the connection or disconnection between the gas input module and the gas output module.

[0031] In the cooling and dehumidifying device of the embodiment of the present application, the control module 20 is connected to the gas input module by signal, and can control the connection or disconnection between the gas input module and the gas output module. When the conveying device starts to convey tobacco stems, the control module 20 transmits a signal to the gas input module, so that it is connected to the gas output module, and compressed air is delivered to the gas output module.

[0032] The cooling and dehumidifying device for tobacco stem conveying equipment in the embodiment of the present application is provided with a gas output module above the tobacco stem conveying equipment, and its input compressed air is controlled by a signal connection between the control module 20 and the gas input module. The compressed air is blown out from the gas output module, thereby accelerating the air flow rate in the space around the tobacco stems, and at the same time, the surrounding dry air can be drawn in, so that the tobacco stems continuously conveyed on the conveying equipment are suspended and tumbled forward, the temperature of the tobacco stems is reduced, and the surface water of the tobacco stems is quickly separated, thereby accelerating the cooling speed and dehumidification speed of the tobacco stems, so that the tobacco stems can be quickly cooled and dehumidified.

[0033] In some embodiments, the gas input module includes a first air inlet pipe and a first solenoid valve, the first solenoid valve is arranged between the first air inlet pipe and the gas output module, and the first solenoid valve is connected to the control module 20 by signal. In the embodiment of the present application, the control module 20 is connected to the first solenoid valve by signal, controls the opening or closing of the first solenoid valve, and connects or disconnects the gas input module and the gas output module. When the tobacco stem conveying device is started, the control module 20 opens the first solenoid valve to realize the automation of the cooling and dehumidification device.

[0034] Furthermore, the gas input module further includes a first filter, which is arranged on the first air inlet pipe. The first filter can filter impurities and oil in the compressed air in the first air inlet pipe, ensure the purity of the compressed air, protect each module, and prevent impurities and oil from contaminating tobacco stems.

[0035] In some other embodiments, the gas input module includes a second air inlet pipe 11, a switch assembly and a pneumatic valve 12, the switch assembly is connected to the second air inlet pipe 11, the pneumatic valve 12 is connected to the switch assembly, one end of the pneumatic valve 12 is connected to the gas input module, and the other end is connected to the gas output module, and the switch assembly is connected to the control module 20 by signal to control the opening or closing of the switch assembly. In the embodiment of the present application, the control module 20 is connected to the switch assembly by signal, the switch assembly is connected to the pneumatic valve 12, and the control module 20 controls the switch assembly to open so that the compressed air is transported to the pneumatic valve 12 along the pipeline and opens it, so that the compressed air is transported from the gas input module to the gas output module.

[0036] Furthermore, the gas input module further includes a second filter 15, and the second filter 15 is arranged on the second air inlet pipe 11. Figure 1 The second filter 15 can filter impurities and oil in the compressed air in the second air inlet pipe 11, ensure the purity of the compressed air, protect each module, and prevent impurities and oil from contaminating the tobacco stems.

[0037] Furthermore, the switch assembly includes a first pressure regulating valve 13 and a second solenoid valve 14, the first pressure regulating valve 13 is arranged between the second air inlet pipe 11 and the second solenoid valve 14, the pneumatic valve 12 is connected to the second solenoid valve 14, and the second solenoid valve 14 is connected to the control module 20 signal. In the embodiment of the present application, the first pressure regulating valve 13 is used to adjust the pressure of the compressed air delivered by the gas input module, which can ensure the stability of the control gas circuit pressure and protect the rear pneumatic valve 12 from damage. The compressed air conducts through the pneumatic valve 12, so that the gas input module is connected to the gas output module. When the conveying equipment is started, the control module 20 controls the second solenoid valve 14 to open, and the compressed air after pressure regulation passes through the second solenoid valve 14 and conducts through the pneumatic valve 12.

[0038] In some embodiments, the gas output module includes an air compression main pipe 31 and a blow pipe 32. The air compression main pipe 31 is connected to the gas input module, and the blow pipe 32 is connected to the air compression main pipe 31. The blow pipe 32 is arranged above the conveying device to blow the tobacco stems. In the embodiment of the present application, the compressed air is transported from the gas input module to the air compression main pipe 31 of the gas output module, and then distributed from the air compression main pipe 31 to the blow pipe 32 as needed. The air compression main pipe 31 has the function of storing and distributing compressed air.

[0039] Furthermore, there are multiple blowpipes 32, and the multiple blowpipes 32 are evenly arranged on the air compressor main pipe 31. Figure 1 The air compressor main pipe 31 distributes the compressed air to the blow pipes 32, which are arranged above the tobacco stems of the conveying device. A certain distance is set between the multiple blow pipes 32, so that the air in the space around the conveying device can form convection, ensuring the cooling and dehumidification effect of the tobacco stems.

[0040] Furthermore, a plurality of blowing holes 33 are provided on the blowing pipe 32, and the blowing holes 33 are evenly distributed on the blowing pipe 32. Figure 2 The multiple blowing holes 33 on the blow pipe 32 can evenly blow out the compressed air. The air flow rate of each blowing hole 33 is constant, which can cool and dehumidify the tobacco stems on the conveying equipment.

[0041] In some embodiments, the gas output module further includes a plurality of second pressure regulating valves 34, and each blowpipe 32 is provided with a second pressure regulating valve 34. Figure 2 The second pressure regulating valve 34 is arranged between the air main pipe and the multiple blow pipes 32. It can evenly distribute the compressed air to the blow pipes 32 and adjust the pressure of the compressed air. While ensuring the best effect of cooling and dehumidifying the tobacco stems, it can also prevent the tobacco stems from being blown out of the conveying equipment due to excessive compressed air.

[0042] The tobacco stem cooling and dehumidification device for tobacco stem conveying equipment in the embodiment of the present application is installed above the tobacco stem conveying equipment and uses compressed air as a medium. The compressed air passes through a stop valve and a filter along an air inlet pipe. The filter can filter out impurities and oil in the compressed air, thereby ensuring the purity of the compressed air, protecting system components, and preventing impurities and oil from contaminating the tobacco stems. The stop valve can conveniently shut off the compressed air in the device.

[0043] The compressed air intake pipe is divided into two paths: one is the execution air path, and the compressed air directly enters the device under the control of the pneumatic valve 12 on the intake pipe, and participates in the cooling and dehumidification of the tobacco stems; the other is the control air path: the control air path composed of the first pressure regulating valve 13 and the second solenoid valve 14. After the compressed air is adjusted to a certain pressure by the first pressure regulating valve 13, the pressure of the control air path can be guaranteed to be stable, and the rear pneumatic valve 12 can be protected from damage; when the control module 20 receives the device start-up working signal, the control module 20 electrical signal conducts the first solenoid valve, controls the air source to conduct the pneumatic valve 12, and executes the compressed air to open.

[0044] The pneumatic valve 12 conducts the compressed air in the first air inlet pipe, and the compressed air enters the air compression main pipe 31 along the first air inlet pipe. The air compression main pipe 31 has the function of storing and distributing the compressed air. The air compression main pipe 31 is installed and connected with multiple groups of blow pipes 32. The interval between the blow pipes 32 is 150mm to 200mm. A certain interval is set between the blow pipes 32, so that the air convection in the space around the conveying equipment can be achieved to ensure the cooling and dehumidification effect of the tobacco stems. A plurality of blow holes 33 with an aperture of 1.3mm are drilled on the blow pipe 32. The blow holes 33 with the above aperture size can ensure that the air flow rate of each blow hole 33 on the blow pipe 32 is constant, and a second pressure regulating valve 34 is installed. By adjusting the appropriate pressure of each second pressure regulating valve 34, the optimal effect of cooling and dehumidifying the tobacco stems can be ensured, and the tobacco stems can be blown out of the conveying equipment due to excessive compressed air flow rate.

[0045] When the conveying equipment needs to start production, the control module 20 starts the transmission motor, and the conveying equipment starts to run. At the same time, the control module 20 sends a conduction electrical signal to the second solenoid valve 14, and controls the air source to conduct the pneumatic valve 12 along the second air inlet pipe 11. The pneumatic valve 12 conducts the compressed air in the second air inlet pipe 11, and the compressed air enters the air compression main pipe 31 along the second air inlet pipe 11. The air compression main pipe 31 distributes the compressed air in the multiple groups of blowpipes 32, and the compressed air with a certain pressure adjusted by the second pressure regulating valve 34 is blown out from the blow hole 33, driving the air flow rate around the conveying equipment to accelerate, and at the same time, the surrounding dry and room temperature air can be drawn over, so that the continuously conveyed tobacco stems are suspended and rolled forward on the conveying equipment, the temperature on the tobacco stems is reduced, the surface water is quickly separated, the cooling speed and dehumidification speed of the tobacco stems are also accelerated, and the water vapor and heat discharged from the tobacco stems are discharged from the intervals between the blowpipes 32, so as to achieve the purpose of cooling and dehumidifying the tobacco stems.
