Description

Technical Field

[0001] The present invention relates to the field of cigarette filter rod and cigarette circumference measurement, and specifically relates to a circumference automatic calibration device and calibration method for a comprehensive test bench of filter rods and cigarettes. Background Art

[0002] In the tobacco industry, important indicators required to be inspected in the physical properties of cigarettes and filter rods are important technical indicators for standardizing cigarette production. During the production process, relevant technical indicators need to be strictly detected. The on-line comprehensive test bench used for detection needs to test cigarettes and filter rods one by one, and the circumference is an important item among the important indicators. In order to ensure the continuity of the test and the accuracy of the test data, there is a need for a device that can automatically calibrate the circumference.

[0003] The existing calibration method uses manual timing calibration. During calibration, the machine needs to be stopped for calibration, and a standard rod is placed in the measuring cylinder for measurement and calibration. Its main defects are: 1. It is necessary to stop the machine for measurement and calibration; 2. Manual measurement is required, and there are many uncontrollable factors.

[0004] In the prior art, there are also many filter rod circumference measurements with low accuracy and low precision. For example, a general calibration part for a tobacco-specific circumference measuring instrument disclosed in CN202022257032.3 has low accuracy and stability in measuring the circumference. Summary of the Invention

[0005] The purpose of the present invention is to provide a circumference automatic calibration device for a comprehensive test bench of filter rods and cigarettes that can replace manual calibration, which can be calibrated without stopping the machine according to the set time, improve the detection efficiency, and ensure the accuracy and stability of the data.

[0016] The following are specific embodiments of the present invention, and the technical solutions of the present invention will be further described in conjunction with the drawings, but the present invention is not limited to these embodiments.

[0017] As Figure 1 shown, a circumferential automatic calibration device for a comprehensive test bench of filter rods and cigarettes includes a guide rail 4, a slide block 5 is connected to the guide rail 4, a servo motor 1 is arranged below the guide rail 4, the output end of the servo motor 1 is connected to a toothed belt 2, a pulley 3 is wound on the toothed belt 2, the upper end of the toothed belt 2 is fixedly connected to the slide block 5, and the right end of the slide block 5 is sequentially provided with a calibration station A 6, a calibration station B 7, a measurement station 8 and a manual calibration station from left to right. A negative pressure adsorption device 10 is arranged at the lower right end of the slide block 5, a photoelectric measurement sensor 9 is arranged at the upper end of the negative pressure adsorption device 10, and a reference adjustment seat 11 is arranged below the negative pressure adsorption device 10.

[0018] The calibration station A 6 and the calibration station B 7 can place standard rods.

[0019] The reference adjustment seat 11 and the negative pressure adsorption device 10 are in a straight line in the vertical direction.

[0020] The guide rail 4 is a high-precision guide rail.

[0021] Working principle and calibration method of the present invention:

[0022] When the device is working, the servo motor 1 drives the toothed belt 2 to rotate. Under the action of the pulley 3, the slider 5 on the toothed belt 2 moves along the guide rail 4 to the corresponding station for measurement work. When measuring the filter rod, the workpiece to be measured is placed in the measurement station 8. At the same time, the slider 5 moves along the guide rail 4. When the measurement station 8 just stops above the negative pressure adsorption device 10, the negative pressure adsorption device 10 starts and adsorbs the workpiece to be measured. At the same time, the photoelectric measurement sensor 9 can measure the circumference data of the workpiece to be measured and feedback it to the control system. When timed data measurement is required or abnormal data needs to be calibrated, the calibration station A6 and calibration station B 7 equipped with standard parts are measured and calibrated according to the above method in sequence. Finally, in the non-automatic case, the slider 5 can also be moved to the leftmost end, and the workpiece to be measured or the standard rod can be manually placed into the negative pressure adsorption device 10 to conduct manual verification measurement for automatic calibration, further ensuring the accuracy of the measurement. If the workpiece to be measured is relatively long, the reference adjustment seat 11 can calibrate the position of the workpiece to be measured, further ensuring the accuracy and stability of the data measurement.

[0023] The present invention adopts a high-precision guide rail 4, which further ensures the accuracy of the moving distance of the slider 5 and lays a foundation for the next precise measurement.

[0024] In short, the present invention can replace manual circumferential calibration, can be calibrated without stopping the machine according to the set time, and ensures the accuracy and stability of the data.

[0025] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
