Description

Technical Field

[0001] The utility model relates to the technical field of tobacco detection equipment, in particular to a handheld cigarette circumferential surface laser punching detection device. Background Art

[0002] As consumers pay more and more attention to the health of smoking, slim and medium cigarettes with relatively less harm have developed rapidly. However, due to the reduction in the diameter of the cigarette, the resistance during inhalation increases, which makes it more difficult for consumers to inhale, resulting in a poor sensory experience. To solve this problem, most companies use online laser drilling technology, which uses a high-energy laser beam to penetrate the tipping paper and filter rod paper at the same time, forming tiny holes of a certain diameter and depth on the circumferential surface of the filter end of the cigarette, thereby reducing the resistance during inhalation of the cigarette and increasing the smoothness of inhalation. At the same time, due to the increase in the number of holes in the cigarette, more air enters the consumer's mouth from the circumferential end of the filter when the cigarette is burned, thereby further diluting the smoke volume, reducing the consumer's intake of harmful substances (total particulate matter and tar, etc.), and improving the consumer's sense of smooth inhalation and sensory satisfaction.

[0003] The popularization and application of online laser drilling technology has promoted the rapid development of slim and medium cigarette specifications. However, due to the easy dirtiness of the focusing lens of online laser drilling, blockage by foreign matter, or fluctuations in the material itself and the circumference of the cigarette, the laser beam may not penetrate the cigarette paper or filter rod paper; or due to abnormalities such as failures of the online drilling device itself, the depth or diameter of the hole punched in the cigarette is too large, resulting in abnormal cigarette suction resistance and quality risks. Moreover, due to the small diameter of the laser beam, the aperture of the laser drilling is very small, and the production speed of the cigarette unit is fast. Under normal conditions, the naked eye cannot identify whether the holes on the surface of the cigarette are missing, penetrated, or continuous, and cannot judge the aperture and hole spacing of the cigarette holes, which makes it impossible to effectively correct the equipment parameters and the gap between parts, etc., resulting in a large number of unqualified products and a large amount of economic losses.

[0004] In response to the above problems, different cigarette manufacturers use different methods for detection. For example, Chinese Patent 201910901476.5 provides a cigarette laser punching detection device. However, when taking and placing cigarettes, the device needs to first adjust the positioning module and the positioning block, and then place the cigarette horizontally into the groove of the positioning module, and then push the cigarette horizontally so that the cigarette rests on the positioning block. Therefore, it is inconvenient to take and place cigarettes. In addition, the equipment has a complex structure and a large size, which is not conducive to the operator to use the device conveniently and quickly.

[0005] Another detection method mainly relies on visual imaging technology. For example, Chinese patents 202121933151.4, 202121604302.1 and 202223367858.0 use this technology to add a visual detection device to the cigarette making unit to realize the hole shape detection after laser punching. However, since the cigarette making unit runs at a high speed and the holes are distributed on the entire circumference of the filter end of the cigarette (360 degrees), visual imaging detection can only detect holes on part of the cross section, and it is difficult to accurately determine the hole spacing, hole depth and hole distribution. Since only part of the cross section can be detected, it is difficult for operators to determine whether the cigarette punching is in a reasonable and effective state, so it is impossible to effectively adjust the laser punching parameters and component gaps, resulting in increased product quality risks. Moreover, relying solely on visual imaging for online detection, ordinary front-line employees have deviations in knowledge structure, etc., and it is difficult to independently correct parameters. Professional personnel are required for maintenance, which increases the difficulty of work. Utility Model Content

Provide important information support.

[0033] The positioning hole 11 is located on the upper wall of the box body 1, the positioning sleeve 3 is located in the box body 1, and the positioning sleeve 3 is arranged vertically to the upper wall of the box body 1.
