Description

Technical Field

[0001] The utility model relates to the technical field of cigarette production, in particular to a mounting bracket for a vacuum rehumidification core temperature and humidity detection device. Background Art

[0002] As a special process for tobacco leaf processing, vacuum conditioning mainly uses vacuum to increase the cell volume of tobacco leaves so that they can absorb water better. At the same time, vacuum conditioning also has the effect of killing insects and removing green impurities. The main parameters of vacuum conditioning tobacco leaf processing include the vacuum degree when vacuum is stopped, the vacuum degree when moisture is converted to water, the vacuum degree when moisture is converted to steam, the holding time of moisture, the vacuum degree when vacuum is stopped after vacuuming, the opening degree of moisture steam, etc. According to the above parameters, the intensity of vacuum conditioning tobacco leaf processing can be divided into light, medium and heavy. After processing, it is mainly reflected by the temperature and humidity of the core.

[0003] At present, the main processing parameters of vacuum rehumidification can be monitored in real time on the winCC interface. The temperature and humidity detection of the core wrapping of the vacuum rehumidification line in the tobacco making workshop of the cigarette factory is mainly measured manually using infrared thermometers and infrared moisture meters. When measuring, it is necessary to use a nail rake to manually pry open the tobacco leaves in the tobacco frame after vacuum rehumidification treatment, and then quickly use the measuring instrument to measure the corresponding indicators. However, when measuring indicators after prying open the tobacco leaves with a nail rake, the temperature and humidity will decrease over time, and the measured values ​​will be less than the true values. In addition, when manually using infrared thermometers and infrared moisture meters to measure indicators, it is difficult to ensure consistency in the detection distance, resulting in errors in the measured values.

[0028] like Figure 1 and Figure 2 As shown, the utility model provides a mounting bracket for a vacuum rehumidification core-wrapped temperature and humidity detection device, including a hanger 100, a cylinder 200 and a mounting assembly 300. The hanger 100 is mounted on the frame of the roller conveyor 10; the side wall of the cylinder 200 is connected with a connecting rod 210, the connecting rod 210 is connected to the top of the hanger 100, and the telescopic end of the cylinder 200 extends in the vertical direction; the mounting assembly 300 includes a back plate 310, a cover plate 320 and a baffle 330, the back plate 310 is connected to the telescopic end of the cylinder 200, the cover plate 320 and the baffle 330 are arranged on the same side of the back plate 310, the cover plate 320 is provided with a first through hole 321 in the vertical direction, the baffle 330 is provided with a second through hole 331, the temperature and humidity detection device is mounted on the back plate 310, the probe of the temperature and humidity detection device passes through the first through hole 321, and the transmission line of the temperature and humidity detection device passes through the second through hole 331.

[0029] The vacuum rehydration core temperature and humidity detection device installation bracket provided by the utility model is installed on the back plate 310 before use, the probe of the temperature and humidity detection device passes through the first through hole 321, and the transmission line of the temperature and humidity detection device passes through the second through hole 331.

The vacuum rehumidification core temperature and humidity detection device installation bracket changes the currently used non-contact measurement method to a contact measurement method, thereby improving the detection precision and accuracy. The cylinder 200 is used to replace the manual insertion and removal process of the temperature and humidity sensor device, thereby effectively avoiding the depth deviation caused by manual insertion and removal, and ensuring the consistency of the measurement.

[0030] In some embodiments, a scraper 110 is provided on the hanger 100, and a channel hole 111 is formed on the scraper 110 to be aligned with the first through hole 321, and the probe of the temperature and humidity detection device can pass through the channel hole 111. In the process of the telescopic end of the cylinder 200 extending downward to drive the mounting assembly 300 to move downward, the mounting assembly 300 drives the temperature and humidity detection device to move downward, and the probe of the temperature and humidity detection device passes through the channel hole 111 and enters the smoke sheet in the smoke frame 20.

[0031] In some embodiments, the top of the hanger 100 is connected to a mounting frame 120, which extends in the vertical direction. The bottom of the mounting frame 120 is provided with a first proximity switch 121, which is located at the downward movement limit position of the mounting assembly 300.

During operation, the roller conveyor 10 conveys the cigarette frame 20 with the built-in vacuum rehumidified cigarette to the bottom of the temperature and humidity detection device. After the diffuse reflection photoelectric switch 11 detects the cigarette frame 20, it transmits the signal to the PLC control module, and then the PLC control module issues a command to control the roller conveyor 10 to stop, and the cigarette frame 20 enters the detection station. Then the PLC control module controls the telescopic end of the cylinder 200 to move downward, driving the installation assembly 300 and the temperature and humidity detection device to move downward together. The probe of the temperature and humidity detection device passes through the channel hole 111 on the scraper 110 and enters the cigarette frame 20. After the telescopic end of the cylinder 200 drives the installation assembly 300 to move downward and is finally detected by the first proximity switch 121, that is, after the probe of the temperature and humidity detection device reaches the detection position, the cylinder 200 stops moving. After the reading of the temperature and humidity detection device stabilizes (this time can be adjusted by the PLC control program delay), the telescopic end of the cylinder 200 moves upward, driving the installation assembly 300 and the temperature and humidity detection device to move upward. The installation assembly 300 is finally detected by the second proximity switch 122 and returns to the initial position. During the return process, the remaining cigarette pieces on the probe of the temperature and humidity detection device can be scraped off by the scraper 110 to complete the simple cleaning of the probe. After the mounting assembly 300 returns to the initial position, the second proximity switch 122 transmits a signal to the PLC control module, and the PLC control module controls the roller conveyor 10 to move and send the cigarette frame 20 out of the inspection station.
