Description

Technical Field

[0001] This utility model relates to the field of tobacco processing technology, and in particular to a microwave weight detection and control system for a dual-track cigarette machine. Background Technology

[0002] Cigarette weight is a key indicator of cigarette quality, crucial for ensuring product quality and consumer experience. Accurate weight detection ensures each cigarette meets standards, preventing overweight, underweight, or stubby cigarettes, thus guaranteeing consistency and quality. The stability of cigarette weight directly affects taste and combustibility; accurate weight detection helps provide a consistent smoking experience, meeting consumer needs. Cigarette products must comply with national and international tobacco regulations and standards; weight detection is a vital step in ensuring compliance and helping companies avoid legal risks. However, currently available microwave weight detection machines for cigarette machines have significant drawbacks: First, the original machines use a Sr-90 radioactive source as the weight control detection head. This source is radioactive, posing a safety threat to operators, especially maintenance workers. The inherent characteristics of the radioactive source require periodic benchmark calibration, causing inconvenience in use and maintenance. Furthermore, the control accuracy of the microwave weight detection machine decreases as the radioactive source attenuates. Therefore, designing a dual-track microwave weight detection control system for cigarette machines is essential. Utility Model Content

[0003] The purpose of this invention is to provide a dual-track microwave weight detection and control system for cigarette machines, in order to solve the problems of existing radiation sources which pose a safety threat to operators, especially maintenance workers; the inherent characteristics of radiation sources which require the system to be periodically calibrated, causing inconvenience in use and maintenance; and the fact that the control accuracy of the microwave weight detection machine for cigarette machines decreases as the radiation source attenuates.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a microwave weight detection and control system for a dual-track cigarette machine, comprising a supporting shell, a smoke inlet pipe, a supporting inner shell, a power module, a temperature control board, a microwave source system, an isolator, a detector amplifier, a smoke outlet pipe, a resonant cavity, and a supporting plate. The supporting inner shell is fixedly connected to the inner wall of the supporting shell, and a supporting plate is fixedly connected to the inner wall of the supporting inner shell. A main control board is fixedly connected to the supporting plate.

[0005] As a further technical solution of this utility model, a partition is fixedly connected in the through groove of the supporting shell, and a cover plate is fixedly connected on the supporting shell.

[0006] As a further technical solution of this utility model, a power module and a temperature control board are fixedly connected to the top of the support plate, and an isolator and a detector amplifier are fixedly connected to the bottom of the support plate, with the isolator closely attached to the detector amplifier.

[0007] As a further technical solution of this utility model, the main control board is provided with a control component, which consists of an information acquisition module, a weight control module, a cigarette sampling and rejection module, and a host computer control module. The information acquisition module controls and connects to the weight control module, the weight control module controls and connects to the cigarette sampling and rejection module, and the cigarette sampling and rejection module controls and connects to the host computer control module.

[0008] As a further technical solution of this utility model, a resonant cavity is fixedly connected in the through groove opened on the support plate.

[0009] As a further technical solution of this utility model, a smoke inlet pipe is symmetrically and fixedly connected to one side of the resonant cavity, and a smoke outlet pipe is symmetrically and fixedly connected to the other side of the resonant cavity, with a smoke inlet pipe fixedly connected to the smoke outlet pipe.

[0010] As a further technical solution of this utility model, a microwave source system is fixedly connected to the inner wall of the supporting inner shell, and the supporting inner shell is tightly attached to the cover plate.

[0011] This utility model provides a microwave weight detection and control system for a dual-track cigarette rolling machine. Its advantages are as follows: During the process of a cigarette entering through the inlet pipe and exiting through the outlet pipe, the microwaves emitted by the microwave transmitter in the microwave source system penetrate the cigarette and are partially absorbed or scattered. The detector amplifier amplifies the emitted microwaves, and the resonant cavity selects electromagnetic or acoustic waves of a specific frequency while suppressing microwaves of other frequencies. Since tobacco shreds have different absorption characteristics for microwaves, the density and distribution of the tobacco shreds in the cigarette can be indirectly determined by measuring the change in the intensity of the reflected microwaves. The information acquisition module collects the cigarette density signal through the microwave source system, converts the signal into a digital quantity, and transmits it to the weight control module via bus communication. The weight control module then calculates the weight and segmented density value of a single cigarette based on the cigarette pack synchronization pulse signal. Finally, the weight control module calculates the average weight of a single cigarette from multiple consecutive cigarettes and controls the dead zone accordingly. The weight is adjusted using set values. Simultaneously, the weight control module transmits the weight data of each cigarette to the cigarette sampling and rejection module via bus communication. The cigarette sampling and rejection module compares the cigarette weight and segment density values ​​transmitted from the weight control module with the rejection thresholds set on the host computer control module for overweight, underweight, soft spots, hard spots, and loose ends. If any of these indicators exceeds the set value, the cigarette is considered unqualified. If the corresponding rejection function is activated, the cigarette is rejected as waste. The number of rejected cigarettes and the corresponding method are transmitted to the host computer control module for data statistics, enabling rapid detection and rejection of unqualified cigarettes, significantly improving work efficiency. Based on the current measured cigarette weight, the cigarette weight can be precisely adjusted to the predetermined value in one step via the touchscreen, eliminating the need for repeated measurements and adjustments. Various cigarette brand parameters can be pre-set; when changing brands, simply select the brand name, and all parameters are automatically generated. Attached Figure Description

[0021] Please see the appendix Figure 1 -Appendix Figure 5 This utility model provides an embodiment of a microwave weight detection and control system for a dual-track cigarette machine, comprising a supporting outer shell 1, a smoke inlet pipe 2, a supporting inner shell 3, a power module 5, a temperature control board 6, a microwave source system 7, an isolator 8, a detector amplifier 9, a smoke outlet pipe 10, a resonant cavity 11, and a support plate 14. The supporting inner shell 3 is fixedly connected to the inner wall of the supporting outer shell 1, and the support plate 14 is fixedly connected to the inner wall of the supporting inner shell 3. A main control board 4 is fixedly connected to the support plate 14. A partition 12 is fixedly connected to a through slot in the supporting outer shell 1, and a cover plate 13 is fixedly connected to the supporting outer shell 1. The power module 5 and the temperature control board 6 are fixedly connected to the top of the support plate 14, and the isolator 8 and the detector amplifier 9 are fixedly connected to the bottom of the support plate 14, with the isolator 8 closely attached to the detector amplifier 9. A control component 15 is provided in the main control board 4, which consists of an information acquisition module 1501 and a weight control module 1502. The system consists of a block 1502, a cigarette sampling and rejection module 1503, and a host computer control module 1504. The information acquisition module 1501 controls and connects to the weight control module 1502, the weight control module 1502 controls and connects to the cigarette sampling and rejection module 1503, and the cigarette sampling and rejection module 1503 controls and connects to the host computer control module 1504. A resonant cavity 11 is fixedly connected to a through slot on the support plate 14. A cigarette inlet pipe 2 is symmetrically fixedly connected to one side of the resonant cavity 11, and a cigarette outlet pipe 10 is symmetrically fixedly connected to the other side of the resonant cavity 11. The cigarette inlet pipe 2 is fixedly connected to the cigarette outlet pipe 10. The resonant cavity 11 can select a certain frequency of microwave and suppress microwaves of other frequencies. A microwave source system 7 is fixedly connected to the inner wall of the inner support shell 3. The inner support shell 3 is close to the cover plate 13. The microwave source system 7 can emit and absorb microwaves and collect information about the cigarettes based on the reflected microwaves.

[0022] Specifically, in use, the cigarette first enters through the inlet pipe 2 and travels to the outlet pipe 10. During this process, the microwaves emitted by the microwave transmitter in the microwave source system 7 penetrate the cigarette and are partially absorbed or scattered. The detector amplifier 9 amplifies the emitted microwaves, and the resonant cavity 11 selects electromagnetic waves or sound waves of a specific frequency while suppressing microwaves of other frequencies. Since tobacco shreds have different absorption characteristics for microwaves, the density and distribution of the tobacco shreds in the cigarette can be indirectly determined by measuring the change in the intensity of the reflected microwaves. The information acquisition module 1501 acquires the cigarette density signal through the microwave source system 7, converts the signal into a digital quantity, and transmits it to the weight control module 1502 via bus communication. The weight control module 1502 then calculates the weight and segmented density value of a single cigarette based on the cigarette pack synchronization pulse signal. Finally, the weight control module 1502 calculates the average weight of a single cigarette from multiple consecutive cigarettes and adjusts the weight according to the set value of the control dead zone. The external weight control module 1502 also transmits the weight data of each cigarette to the cigarette sampling and rejection module 1503 via bus communication. The cigarette sampling and rejection module 1503 compares the cigarette weight and cigarette segment density value transmitted from the weight control module 1502 with the rejection thresholds set on the host computer control module 1504 for overweight, underweight, soft spot, hard spot, and loose end. If any of these indicators exceeds the set value, the cigarette is considered unqualified. If the corresponding rejection function is activated, the cigarette is rejected as waste. At the same time, the number of rejected cigarettes and the corresponding method are transmitted to the host computer control module 1504 for data statistics, which quickly detects and rejects unqualified cigarettes, greatly improving work efficiency. Based on the actual measured weight of cigarettes on the machine, the cigarette weight can also be precisely adjusted to the predetermined value in one step via the touch screen, without the need for repeated measurement and adjustment. The parameters of various cigarette brands can be set in advance. When changing brands during production, only the brand name needs to be selected, and all parameters are automatically generated.
