[0057] At present, the tobacco industry is developing rapidly in the new technology of heating tobacco without burning. The thin sheets of heated cigarettes are mainly produced by rolling. In the rolling process of heated cigarette thin sheets, there are often problems such as uneven force between rollers, resulting in uneven quality of tobacco thin sheets. If the operator cannot quickly detect the thickness data of tobacco thin sheets and promptly identify the defects in the tobacco rolling production process, it will lead to continuous loss of raw materials and cause serious economic losses.
[0058] At least to address the above problems, the following embodiments of the present application provide a tobacco sheet processing device, which effectively detects the thickness of the tobacco sheet and the force applied to the pressure roller, thereby improving the production quality of the tobacco sheet. At the same time, the tobacco sheet processing device provided by the present application also has the advantages of accurate processing and easy production.
[0059] The principle and implementation of a tobacco sheet processing device provided by this embodiment will be described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can understand the tobacco sheet processing device of this embodiment without creative work.
[0060] Figure 1 It shows an overall schematic diagram of a tobacco sheet processing device 1 in one embodiment of the present application. Figure 2 The figure shows a partial schematic diagram of a tobacco sheet processing device 1 in one embodiment of the present application. Figure 1 and Figure 2 As shown, the tobacco sheet processing device 1 includes: a force applying mechanism 2 and a pressure sensor 3, at least two pressing rollers 4, a support frame 5, a probe 6 and a servo motor 7.
[0061] The pressing rollers 4 are arranged on the support frame 5, and there is a gap between the pressing rollers 4. The pressing rollers 4 are used to roll the tobacco sheets passing through the gap. Specifically, the pressing rollers 4 can make the tobacco material produce continuous plastic deformation by rolling, and the tobacco material is compressed by the pressing rollers 4 with a reduced cross-section and increased length, thereby being pressed into tobacco sheets.
[0062] For example, see Figure 3 and Figure 4, the tobacco sheet processing device 1 may include a plurality of roller groups, wherein each roller group includes two rollers. For example, roller group 41 includes roller 411 and roller 412, roller group 42 includes roller 421 and roller 422, ..., roller group 4n includes roller 4n1 and roller 4n2. Taking roller group 41 as an example, there is a gap g between roller 411 and roller 412. During the processing, a forward force is applied to the tobacco sheet so that the tobacco sheet passes through the gap g. Rollers 411 and 412 will roll the tobacco sheet passing through the gap g, and the thickness of the tobacco sheet after rolling depends on the width of the gap g.
[0063] The probe 6 is disposed on the support frame 5 and is used to measure the thickness of the tobacco sheet.
[0064] The force applying mechanism 2 is used to apply a force to the pressure roller 4 under the drive of the servo motor 7 , and the gap g is determined by the magnitude of the force.
[0065] The pressure sensor 3 is used to detect the magnitude of the force.
[0066] For example, the pressure sensor 3 can sense the magnitude of the force through the piezoelectric material on the surface of the pressure roller 4 and convert it into an electrical signal, which is proportional to the magnitude of the force applied to the pressure roller 4. By amplifying, recording, measuring, and other processing of the electrical signal, the pressure sensor 3 can accurately measure the magnitude of the force.
[0067] See also Figure 5 The servo motor 7 drives the force applying mechanism 2 to apply a force to the pressure roller 4 , and the pressure sensor 3 detects the magnitude of the force on the pressure roller 4 and feeds back the magnitude of the force to the servo motor 7 .
[0068] In some implementations, the rolling method includes hot rolling and cold rolling.
[0069] In some implementations, the support frame 5 is an open roller transmission support that can withstand the pressure, load and other forces generated by the roller 4 during operation, ensuring that the roller 4 can operate stably.
[0070] In some implementations, the probe 6 includes a thermal probe, a light-sensitive probe, a force-sensitive probe, a sound-sensitive probe, a radiation-sensitive probe, a magnetic-sensitive probe, and the like.
[0071] The radioactive sensitive probe may be an infrared probe.
[0072] According to the above description, in the tobacco sheet processing device 1 provided in the embodiment of the present application, the probe 6 arranged on the support frame 5 can detect the thickness of the tobacco sheet rolled by the pressing roller 4, the servo motor 7 can provide driving force to the force applying mechanism 2, and the pressure sensor 3 can detect the force applied by the force applying mechanism 2. By detecting the thickness of the tobacco sheet and the force applied to the pressing roller, the production quality of the tobacco sheet can be better guaranteed.
[0073] Please continue reading Figure 1 and Figure 2 In one embodiment of the present application, the tobacco sheet processing device 1 further includes a hopper (not shown in the figure) and a conveyor belt 8, and the conveyor belt 8 is used to transport the tobacco sheet outward.
[0074] See also Figure 6 The hopper is connected to the tobacco sheet processing device 1 and is used to input tobacco materials into the tobacco sheet processing device 1.
[0075] In one embodiment of the present application, the support frame includes a guide rail (not shown in the figure) for guiding the pressure roller 4 to roll.
[0076] In one embodiment of the present application, the force applying mechanism 2 includes a worm gear, a hand wheel adjustment device and an automatic adjustment device.
[0077] Optionally, the worm includes a single-start worm, a double-start worm and a multi-start worm.
[0078] Please continue reading Figure 1 In one embodiment of the present application, the pressure sensor 3 is disposed between the pressure roller 4 and the force applying mechanism 2 .
[0079] In some implementations, the pressure sensor 3 is disposed on the left side of the pressure roller 4 , and the pressure sensor 3 is disposed on the right side of the force applying mechanism 2 .
[0080] Please continue reading Figure 2 In one embodiment of the present application, the probe 6 includes a transmitting probe 61 and a receiving probe 62 that are arranged opposite to each other.
[0081] In some implementations, the transmitting probe 61 and the receiving probe 62 are respectively an infrared transmitting probe and an infrared receiving probe. The infrared transmitting probe and the infrared receiving probe are arranged opposite to each other, and the thickness of the tobacco sheet can be better detected through the short-range communication between the infrared transmitting probe and the infrared receiving probe.
[0082] In some implementations, the tobacco sheet absorbs the infrared rays emitted by the infrared emitting probe when passing through the probe 6. At this time, the infrared rays of the infrared emitting probe will be attenuated. The infrared receiving probe receives the attenuated infrared rays and determines the thickness of the tobacco sheet based on the degree of infrared attenuation.
[0083] See also Figure 7 Driven by the servo motor 7 , the pressing roller crushes the input material and outputs tobacco slices. The probe 6 detects the thickness of the tobacco slices and feeds back the thickness value to the servo motor 7 .
[0084] Please continue reading Figure 2 In one embodiment of the present application, there are multiple probes 6 and multiple pressure rollers 4, and the probes 6 are arranged at intervals between the multiple pressure rollers 4.
[0085] Please continue reading Figure 3 The transmitting probe 61 is arranged between the pressing rollers 411 and 421, and the receiving probe 62 is arranged between the pressing rollers 412 and 422, as a thickness detection point of the tobacco sheet. The pressing roller 412, the pressing roller 422 and the subsequent pressing roller 4n2 form a horizontal detection surface, which can avoid vibration of the tobacco sheet surface to produce detection errors and improve the accuracy of the probe detection.
[0086] See also Figure 8 The tobacco sheet processing device 1 includes a plurality of probes, each of which includes a transmitting probe and a receiving probe that are relatively arranged. For example, the transmitting probes include 611, 612, ..., 61n, and the receiving probes include 621, 622, ...62n.
[0087] In one embodiment of the present application, the tobacco sheet processing device 1 further includes an optical controller and an optical unit, and the optical controller and the optical unit are respectively connected to the probe 6 via optical cables.
[0088] The optical controller regulates the infrared emission and reception signals of the probe 6 through the optical cable. The optical unit has an imaging function and is connected with the probe 6 to provide better thickness detection for the tobacco sheet.
[0089] In an embodiment of the present application, the number of the servo motors 7 is at least two.
[0090] See also Fig. 9 The tobacco sheet processing device 1 is communicatively connected to the industrial computer, and the power supply device provides power to the tobacco sheet processing device 1 and the industrial computer.
[0091] In summary, the embodiment of the present application provides a tobacco sheet processing device. The tobacco sheet processing device includes a probe, and the probe is used to detect the thickness of the processed tobacco sheet. Through the probe, the operator can timely know the thickness of the currently processed tobacco sheet.
[0092] In addition, in the tobacco sheet processing device, the thickness of the processed tobacco sheet depends on the gap width between the pressing rollers, and the gap width between the pressing rollers is determined by the magnitude of the force applied to the pressing rollers by the force applying mechanism, and the magnitude of the force is determined by the servo motor. Therefore, when the driving force output by the servo motor remains unchanged, the tobacco sheet processing device can continuously and stably process the tobacco sheet.
[0093] Furthermore, if the thickness of the tobacco slices currently processed by the tobacco slice processing device does not meet the processing requirements, the force applied to the pressing roller by the force-applying mechanism can be adjusted manually or automatically, thereby adjusting the gap width between the pressing rollers, and further adjusting the thickness of the tobacco slices. For example, if the tobacco slices currently being processed are too thick, the force applied to the pressing roller by the force-applying mechanism can be increased, thereby reducing the gap width between the pressing rollers, so as to reduce the thickness of the tobacco slices and make the tobacco slices meet the processing requirements again. If the tobacco slices currently being processed are too thin, the force applied to the pressing roller by the force-applying mechanism can be reduced, thereby increasing the gap width between the pressing rollers, so as to increase the thickness of the tobacco slices and make the tobacco slices meet the processing requirements again.
[0094] The descriptions of the processes or structures corresponding to the above-mentioned figures have different emphases. For parts that are not described in detail in a certain process or structure, please refer to the relevant descriptions of other processes or structures.
[0095] The above embodiments are merely illustrative of the principles and effects of the present application and are not intended to limit the present application. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present application. Therefore, all equivalent modifications or changes made by a person of ordinary skill in the art without departing from the spirit and technical ideas disclosed in the present application shall still be covered by the claims of the present application.
