Description

Technical Field

[0001] The utility model relates to the field of cigarette manufacturing, in particular to a dust removal device for a small box appearance detection component. Background Art

[0002] The small box appearance inspection device is a device used to inspect the appearance quality of small packs in the packaging process of cigarette production workshops. Its inspection principle is to use three industrial cameras and three sets of fiber optic detectors to determine the position of the cigarette packs and image the upper and both sides of the small packs of cigarettes. The industrial computer collects the imaged photos, matches the set parameters in the pre-configured software, and removes unqualified cigarette products.

[0003] In actual applications, small box appearance inspection is easily affected by external interference, especially the dust in the cigarette packaging workshop. When the camera for small box appearance inspection is covered with dust, the imaging detection will fail. When the optical fiber detector for small box appearance inspection is covered with dust, it will cause confusion in the cigarette package position detection, which will also affect the imaging effect and reduce the quality of the small box products.

[0004] To this end, the current cleaning solution adopted by tobacco companies is to install a cooling fan and its dustproof cotton inside the independent overall closed structure of the small box appearance inspection device, and manually clean the inside of the device every week according to the equipment maintenance requirements. However, dust will enter the inspection device through the cigarette package conveying channel. The dustproof cotton of the cooling fan cannot block all the dust, and the manual dust cleaning effect is limited. Especially for dust-sensitive cameras and detection optical fibers, the current cleaning solution cannot avoid surface contamination, and the problem of poor detection quality still occurs from time to time.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be interpreted as limiting the present invention.

[0021] The utility model proposes an embodiment of a dust removal device for a small box appearance detection device, specifically, as follows Figure 1 As shown, it includes: a first sub-cylinder 13, a second sub-cylinder 22, a first solenoid valve 23, a second solenoid valve 2, a first rejection fiber cleaning head 7 arranged at the first rejection fiber 8, a first outlet fiber cleaning head 9 arranged at the first outlet fiber 10, a first inlet fiber cleaning head 15 arranged at the first inlet fiber 14, a second outlet fiber cleaning head 4 arranged at the second outlet fiber 3, a second rejection fiber cleaning head 6 arranged at the second rejection fiber 5, a second inlet fiber cleaning head 17 arranged at the second inlet fiber 18, an upper camera cleaning head 12 arranged at the upper camera 11, and a front and rear camera cleaning head 20 for cleaning the rear camera 19 and the front camera 21.

[0022] It can be pointed out that the group of inlet optical fibers are used to detect whether the cigarette pack 16 reaches the inlet position to start the front camera 21 to take the image of the cigarette pack 16 at this angle, and the dust on the surface of the optical fiber detection probe here is cleaned by using the inlet optical fiber cleaning heads respectively provided;
