Detailed Description

The technical solutions in the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present application without making any creative effort, shall fall within the protection scope of the present application.

In the description of the present invention, it is to be understood that the terms "left", "right", "front", "back", "upper", "lower", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

The embodiment discloses a dust collection device for a roller surface scraper of a calender, which takes cleaning of a top calender roller 3 of the calender as an example, and comprises a scraper plate 4, a collection cavity 1 and an induced duct 2 as shown in figures 1-4. The front end of the collecting cavity 1 is a flat and long collecting opening, the left and right length of the collecting opening is consistent with the length of the upper calender roll 3, and the dust and paper scraps which are cleaned can be fully absorbed. The cross section in the collecting cavity 1 gradually shrinks from front to back, and an arc-shaped cover plate 5 is arranged at the upper edge of the collecting opening. The scraper plate 4 is installed on the lower side edge of the collecting port in a matched mode, a connecting plate I6 is arranged at the bottom of the scraper plate 4, a connecting plate II 7 corresponding to the connecting plate I6 is arranged outside the collecting cavity 1, two threaded rods 8 are fixedly installed on the connecting plate I6 in a bilateral symmetry mode, through holes corresponding to the two threaded rods 8 are formed in the connecting plate II 7, and the head end of each threaded rod 8 penetrates through the through hole and is matched with a positioning nut; all the cover is equipped with compression spring 9 on every threaded rod 8, makes compression spring 9 be located between connecting plate I6 and the connecting plate II 7 to enable scraper blade 4 and collect mouthful relative movement along the fore-and-aft direction within a certain limit relatively. The rear end of the collection cavity 1 is communicated with an induced draft pipe 2, and the upper end of the induced draft pipe 2 is communicated with a conventional dedusting induced draft fan device.

Since the degree of pressing of the front end of the blade plate 4 against the roller surface can be changed by adjusting the positioning nut, in order to prevent the roller surface from being damaged, a wear-resistant rubber layer may be laid on the front end of the blade plate 4.

The concrete working process of the dust suction device for the roller surface scraper of the calender is as follows:

firstly, the collection cavity and the induced draft tube are fixedly arranged on calender equipment through a conventional support plate, and the dedusting induced draft tube equipment is communicated with the upper end of the induced draft tube through a pipeline, so that the whole equipment is ready. The front end of the scraper plate is abutted against the surface of the roller, when the calender roller runs, the scraper plate starts to clear away paper scraps and dust on the surface of the roller, the cover plate can effectively prevent the paper scraps and the dust from diffusing upwards, and meanwhile, the air guide pipe is matched with negative pressure air generated by the collection cavity to suck the fallen paper scraps and dust into the collection box so as to prevent the paper scraps and the dust from diffusing and polluting the periphery;

when the cleaning degree of the scraper plate to the roller surface needs to be adjusted, the compression degree of the scraper plate to the roller surface can be adjusted by adjusting the positioning nut, so that the cleaning degree of the roller surface is controlled.
