Description

Technical Field

[0001] The utility model relates to the technical field of tobacco production equipment, in particular to a blowing device for a tube plate tobacco drying machine. Background Art

[0002] In the tobacco processing industry, especially in the tobacco sheet or tobacco shred processing line, the tube-and-plate tobacco dryer is the core equipment of the tobacco drying process. It is used to dry the tobacco. By reducing the moisture content of the tobacco, it can not only accelerate the drying and shaping of the tobacco, but also improve the curl and elasticity of the tobacco, thereby improving the quality and filling value of the tobacco, making it more in line with the requirements of the subsequent cigarette making process.

[0003] However, in actual production, tube-and-sheet tobacco dryers face a common problem: because the hot air circulates in a countercurrent pattern within the drum, some tobacco material, driven by the strong airflow, is easily blown toward and adheres to the upper edge of the drum inlet, causing material accumulation. This accumulation not only leads to excessive tobacco consumption and increased production costs, but also greatly complicates equipment maintenance, requiring operators to spend more time cleaning the equipment, which in turn reduces production efficiency.

[0004] Therefore, how to provide a blowing device for a tube-plate tobacco drying machine to remove tobacco shreds adhering to the drum inlet is a technical problem that those skilled in the art currently need to solve. Utility Model Content

[0005] The utility model aims to provide a blowing device for a tube-plate tobacco drying machine, which solves the technical problem that part of tobacco cut materials are easily adhered to the upper edge area of the drum inlet to form material accumulation.

[0006] To achieve the above-mentioned purpose, the utility model provides a blowing device for a tube sheet wire drying machine, comprising:

[0007] A first air outlet pipe and a second air outlet pipe, wherein the output ends of the first air outlet pipe and the second air outlet pipe are symmetrically arranged on the inner wall of the cavity of the tube plate wire drying machine and are both located above the feed port of the tube plate wire drying machine;

[0008] First blowing holes are evenly spaced apart and arranged at the output end of the first air outlet pipe; second blowing holes are evenly spaced apart and arranged at the output end of the second air outlet pipe;

[0009] A first solenoid valve is provided at the input end of the first air outlet pipe, and a second solenoid valve is provided at the input end of the second air outlet pipe, wherein the air inlets of the first air outlet pipe and the second air outlet pipe are both connected to the air source pipe;

[0010] A control unit establishes a signal connection with both the first solenoid valve and the second solenoid valve. The control unit includes a manual operation module and an automatic operation module. The automatic operation module can automatically control the opening and closing of the first solenoid valve and the second solenoid valve according to preset parameters.

[0011] Preferably, the output ends of the first air outlet pipe and the second air outlet pipe are both curved pipes, so that the output end of the first air outlet pipe and the output end of the second air outlet pipe form a semicircle.

[0012] Preferably, the input ends of the first air outlet pipe and the second air outlet pipe are both arranged outside the tube plate fiber drying machine.

[0013] Preferably, the hole distance between the first blowing hole and the second blowing hole is between 40-60 mm.

[0014] Preferably, the output ends of the first air outlet pipe and the second air outlet pipe are further provided with nozzle heads with adjustable directions.

[0015] Preferably, the output end of the first air outlet pipe is flat.

[0016] Preferably, it further comprises an airflow regulating valve, which is arranged at the connection between the air source pipe and the first air outlet pipe and the second air outlet pipe, and the airflow regulating valve establishes a signal connection with the control unit.

[0017] Preferably, it further includes an industrial camera arranged on the inner wall of the tube plate wire drying machine cavity, the industrial camera establishes a signal connection with the control unit, and the control unit also includes a remote display terminal and a remote control terminal.

[0018] Preferably, the control unit is a PLC.

[0019] Compared to the above-mentioned background technology, the present invention provides a blowing device for a tube sheet wire drying machine. When the tube sheet wire drying machine is operating normally, the automatic operation module of the control unit will start the blowing cycle according to the preset blowing program. For example, the blowing process is started once every 5 minutes, and each blowing lasts for 3 seconds. At this time, the control unit will send an opening signal to the first solenoid valve and the second solenoid valve, so that the airflow in the first and second air outlet pipes is released and evenly ejected through the first and second blowing holes on their respective output ends. The blowing airflow covers the area above the feed port, effectively preventing material accumulation there and promoting the uniform distribution of the material in the wire drying machine. After the blowing is completed, the control unit will send a closing signal to the first and second solenoid valves to stop the air supply.

[0020] At the end of production or when special cleaning is required, the operator can switch to manual operation mode via the control panel on the control unit. In manual mode, the operator can directly control the opening and closing of the first and second solenoid valves, adjusting the frequency and duration of the spraying as needed. Through manual spraying, the operator can more thoroughly clean the accumulated material on the upper edge of the drum's internal feed port, ensuring the cleanliness of the equipment and the smooth progress of the next production.

[0021] In summary, the present application provides a blowing device for a tube sheet wire drying machine, which can automatically clean the accumulated materials on the upper edge of the feed inlet inside the drum, thereby reducing the burden on the operator and improving production efficiency.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] In order to enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0028] See also Figure 1The present application provides a blowing device for a tube plate wire drying machine, which includes a first air outlet pipe 1 and a second air outlet pipe 2. The output ends of the first air outlet pipe 1 and the second air outlet pipe 2 are symmetrically arranged on the inner wall of the cavity of the tube plate wire drying machine 3, and the output ends of the first air outlet pipe 1 and the second air outlet pipe 2 are both located above the feed port of the tube plate wire drying machine 3; a first blowing hole is evenly spaced at the output end of the first air outlet pipe 1; a second blowing hole is evenly spaced at the output end of the second air outlet pipe 2; a first solenoid valve 4 is arranged on the input end of the first air outlet pipe 1, and a second solenoid valve 5 is arranged on the input end of the second air outlet pipe 2, and the air inlets of the first air outlet pipe 1 and the second air outlet pipe 2 are both connected to the air source pipe; a control unit establishes a signal connection with the first solenoid valve 4 and the second solenoid valve 5, and the control unit includes a manual operation module and an automatic operation module. The automatic operation module can automatically control the opening and closing of the first solenoid valve 4 and the second solenoid valve 5 according to preset parameters. When the tube sheet drying machine 3 is operating, the control unit sprays for 3 seconds every 5 minutes, and the spraying is automatic during the production process. At the same time, the manual and automatic control can be switched on the control panel of the on-site control unit. At the end of the production process, manual spraying can be performed to clear the accumulated material on the upper edge of the feed inlet inside the drum.

[0029] Specifically, the output ends of the first air outlet pipe 1 and the second air outlet pipe 2 are symmetrically arranged on the inner wall of the cavity of the tube plate wire drying machine 3, and are both located above the feed port, thereby ensuring that the blowing airflow can evenly cover the feed port area, effectively preventing the material from accumulating on the upper edge of the feed port, and improving the blowing efficiency.

[0030] The first blowing holes and the second blowing holes are evenly spaced at the output ends of the first air outlet pipe 1 and the second air outlet pipe 2, respectively, which ensures the uniformity of the blowing airflow and further improves the blowing effect.

[0031] The first solenoid valve 4 and the second solenoid valve 5 are used to control the air flow of the first air outlet pipe 1 and the second air outlet pipe 2 respectively, thereby achieving precise control of the blowing operation.

[0032] The control unit integrates a manual operation module and an automatic operation module. Users can flexibly select the operation mode according to actual needs. The automatic operation module can automatically adjust the blowing frequency and duration according to preset parameters. For example, in this example, the first solenoid valve 4 and the second solenoid valve 5 are started every 5 minutes, and the first solenoid valve 4 and the second solenoid valve 5 are closed after blowing for 3 seconds, which reduces the burden on the operator and improves production efficiency. At the end of production, it can be switched to manual mode for manual blowing to more thoroughly clean the accumulated materials on the upper edge of the feed port inside the drum.

[0033] The workflow is as follows: When the tube sheet tow dryer 3 is operating normally, the control unit's automatic operation module initiates a blowing cycle according to a preset blowing program. For example, the blowing process is initiated every five minutes, with each blowing cycle lasting three seconds. At this point, the control unit sends an open signal to the first solenoid valve 4 and the second solenoid valve 5, releasing the airflow within the first and second outlet pipes 1 and 2 and evenly ejecting it through the first and second blowing holes at their respective output ends. The blowing airflow covers the area above the feed inlet, effectively preventing material accumulation there and promoting even distribution of the material within the tow dryer. After the blowing process is completed, the control unit sends a close signal to the first and second solenoid valves 4 and 5, stopping the airflow supply.

[0034] At the end of production or when special cleaning is required, the operator can switch to manual operation mode through the control panel on the control unit. In manual mode, the operator can directly control the opening and closing of the first solenoid valve 4 and the second solenoid valve 5, and adjust the frequency and duration of the spraying as needed. Through manual spraying, the operator can more thoroughly clean the accumulated materials on the upper edge of the feed port inside the drum, ensuring the cleanliness of the equipment and the smooth progress of the next production.

[0035] In summary, the present application provides a blowing device for a tube sheet wire drying machine, which can automatically clean the accumulated materials on the upper edge of the feed inlet inside the drum, thereby reducing the burden on the operator and improving production efficiency.

[0036] Based on the above embodiment, the output ends of the first air outlet pipe 1 and the second air outlet pipe 2 are both curved pipes, so that the output ends of the first air outlet pipe 1 and the output ends of the second air outlet pipe 2 form a semicircle, and the input ends of the first air outlet pipe 1 and the second air outlet pipe 2 are both arranged on the outside of the tube plate wire drying machine 3, and the output ends of the first air outlet pipe 1 and the second air outlet pipe 2 are detachably connected to the inner wall of the cavity of the tube plate wire drying machine 3.

[0037] That is to say, the output ends of the first air outlet pipe 1 and the second air outlet pipe 2 are both designed as curved pipes, so that the two output ends can form an approximate semicircular shape in the cavity of the tube plate wire drying machine 3, thereby ensuring that the blowing air flow can fully cover the area above the feed port.

[0038] The input ends of the first and second air outlet pipes 1 and 2 are both located outside the tube sheet tow dryer 3, facilitating connection and maintenance with the gas source pipe. Furthermore, the output ends of the first and second air outlet pipes 1 and 2 are detachably connected to the inner wall of the tube sheet tow dryer 3, allowing for easy removal for cleaning, replacement, or repair when necessary, thereby improving the maintainability and service life of the equipment. The detachable connection method can be a snap-fit connection or a bolt connection.

[0039] Based on the above embodiment, the hole distance between the first blowing hole and the second blowing hole is between 40-60 mm, preferably 50 mm, and the first air outlet pipe 1 and the second air outlet pipe 2 are both stainless steel pipes.

[0040] Specifically, the first blowing hole and the second blowing hole are evenly spaced on the output ends of the first air outlet pipe 1 and the second air outlet pipe 2, respectively, and the hole spacing is precisely controlled between 40-60 mm, preferably 50 mm, to ensure that the blowing airflow can evenly and densely cover the area above the feed port, effectively prevent material accumulation, and promote uniform distribution of material in the silk drying machine.

[0041] Both the first and second outlet pipes 1 and 2 are made of stainless steel. Stainless steel offers excellent corrosion resistance and high-temperature resistance, enabling long-term, stable operation in the high-temperature, high-humidity environment of the tofu drying machine. Furthermore, stainless steel possesses excellent mechanical strength and toughness, capable of withstanding certain airflow pressures and mechanical shocks, ensuring the reliability and durability of the blowing device.

[0042] Based on the above embodiment, the output ends of the first air outlet pipe 1 and the second air outlet pipe 2 are further provided with nozzle heads with adjustable directions, that is, the first blowing hole and the second blowing hole are correspondingly provided with nozzle heads with adjustable directions.

[0043] Specifically, the output ends of the first air outlet pipe 1 and the second air outlet pipe 2 are not only provided with blowing holes, but also have adjustable direction nozzle heads installed on the corresponding blowing holes. The nozzle heads allow the operator to adjust the spray direction according to actual needs to ensure that the spray airflow can cover the target area more accurately and effectively avoid material accumulation or dead corner problems.

[0044] The present application also provides another embodiment, in which the output end of the first air outlet pipe 1 is flat.

[0045] Based on the above embodiment, it further includes an airflow regulating valve, which is arranged at the connection between the air source pipe and the first air outlet pipe and the second air outlet pipe, and the airflow regulating valve establishes a signal connection with the control unit.

[0046] That is to say, the airflow regulating valve is arranged at the connection between the air source pipe and the first air outlet pipe 1 and the second air outlet pipe 2. Its function is to adjust the amount of air entering the first air outlet pipe 1 and the second air outlet pipe 2. By controlling the flow rate of the airflow, the blowing intensity can be adjusted to meet the needs of different blowing effects.

[0047] The airflow regulating valve establishes a signal connection with the control unit. The control unit sends a control instruction to the airflow regulating valve through the signal connection according to the airflow flow required by the user input.

[0048] On the basis of the above embodiment, it also includes an industrial camera arranged on the inner wall of the tube plate wire drying machine 3 cavity, and the industrial camera establishes a signal connection with the control unit. The control unit also includes a remote display end and a remote control end. The remote display end and the remote control end are the same terminal device. The remote control end can control the first solenoid valve 4, the second solenoid valve 5 and the airflow regulating valve, and the remote display end can display the picture of the industrial camera.

[0049] That is, the industrial camera is installed on the inner wall of the tube sheet wire drying machine 3 to capture and transmit the working picture inside the wire drying machine in real time, including the material accumulation in the edge area above the feed port.

[0050] The control unit is also equipped with a remote display and remote control, both integrated into the same terminal device (tablet or smartphone). The remote display displays real-time images of the tofu drying machine captured by the industrial camera, providing operators with a direct understanding of production conditions. The remote control allows operators to remotely control the opening and closing states of the first and second solenoid valves 4 and 5, as well as the airflow control valve, by touch or keystroke, achieving precise control of the blowing mechanism.

[0051] Combined with the real-time monitoring and remote control capabilities of industrial cameras, operators can flexibly adjust the operating parameters of the blowing device based on the actual situation inside the tofu dryer. For example, if excessive material accumulation is detected in a certain area, the blowing intensity can be immediately increased through the remote control terminal. If the airflow needs to be adjusted, the airflow control valve can also be directly operated through the remote control terminal.

[0052] Specifically, the control unit is a PLC (Programmable Logic Controller), that is, the PLC operation panel includes a manual operation module and an automatic operation module, and the user can switch between the manual operation module and the automatic operation module. The PLC is also equipped with a remote display terminal and a remote control terminal (tablet computer) integrated in the same terminal device. The remote control terminal allows the operator to remotely operate the PLC by touching the screen or pressing buttons, etc., to control the switching status of the first solenoid valve 4, the second solenoid valve 5 and the airflow regulating valve and adjust related parameters (such as the blowing time and airflow flow). The remote display terminal can display the internal image of the tofu drying machine captured by the industrial camera and the related data and information processed by the PLC in real time, providing the operator with an intuitive monitoring interface.

[0053] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0054] This document uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from the principles of the present invention, and such improvements and modifications also fall within the scope of protection of the claims of the present invention.
