Detailed Description

Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that: the relative arrangement of the components and steps, numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present application unless it is specifically stated otherwise.

The following description of at least one exemplary embodiment is merely exemplary in nature and is in no way intended to limit the application, its application, or uses.

Techniques, methods, and apparatus known to one of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques, methods, and apparatus should be considered part of the specification.

In all examples shown and discussed herein, any specific values should be construed as merely illustrative, and not a limitation. Thus, other examples of exemplary embodiments may have different values.

The tipping paper scraper device comprises a base body and at least two scrapers. The base is provided with knife grooves with the same quantity as the scrapers, the knife grooves are parallel to each other, and a first plane is arranged between the adjacent knife grooves. At least two scrapers are respectively fixed in the corresponding cutter grooves.

In the embodiment shown in fig. 1-4, the doctor device comprises two doctor blades 2 and 3, and the base body 1 is provided with two doctor grooves 11 and 12.

As an example, the doctor blade is a ceramic doctor blade.

The scraper is fixed on the seat body through the briquetting, is equipped with the indent the same with the quantity of sword groove on the body of briquetting, the shape in indent and the appearance adaptation of scraper protrusion in the sword groove.

As an example, the sipes 11 and 12 have a V-shaped cross section, as shown in fig. 1-4.

As an example, as shown in fig. 1 and 2, the doctor blades 2 and 3 are in the shape of a quadrangular prism, and a first edge of the quadrangular prism is fitted in the V-shaped sipe so that a second edge opposite to the first edge protrudes from the sipe.

In this embodiment, as shown in fig. 4, two V-shaped press grooves 41 and 42 are provided on the body 43 of the press block 4.

As an example, as shown in fig. 1 and 2, the pressing blocks 4 are fixed to both ends of the seat body 1. Specifically, as shown in fig. 3, connecting grooves 13 perpendicular to the axes of the cutter grooves 11 and 12 are formed at both ends of the base 1, the groove bottom of the connecting groove 13 is a second plane, and threaded holes 14 are formed at both ends of the second plane. As shown in fig. 4, both ends of the pressing block are respectively provided with a connection hole 44. As shown in fig. 1 and 2, in the mounted state, the pressing grooves 41 and 42 of the pressing block 4 are fitted with the second edges of the scrapers 2 and 3, the surface of the pressing block is fitted with the second plane, and the pressing block 4 and the base 1 are connected together by the screw 5.

The threaded connection of the pressing block and the seat body ensures firm and reliable connection and simultaneously facilitates the replacement of the scraper.

It will be appreciated that the cross-section of the sipe may be other shapes, such as rectangular, circular, etc., depending on the profile of the doctor blade.

When the tipping paper is produced, the scraper is rotated into the working position, the tipping paper enters the first scraper (for example, the scraper 2) through a certain angle to scrape paper, at the moment, the glue surface of the tipping paper is changed from smooth to rough with burrs, then the tipping paper passes through the first plane between the two scrapers, the tipping paper is straightened, the constancy of the tension value of the tipping paper is ensured, the paper breakage is prevented, then the tipping paper passes through the second scraper (for example, the scraper 3), the roughness of the glue surface of the tipping paper is further improved, and at the moment, the whole paper scraping process is ended.

This application scrapes the hair through a plurality of scrapers to tipping paper, makes the paper scraping quality higher, makes things convenient for the rubberizing process of next step, simultaneously, after parallel transport, has reduced tipping paper scraper's paper angle of drawing, has guaranteed tipping paper conveying's stability. The two-lattice scraper is placed in parallel, so that the pressure of tipping paper acting on the scraper is effectively reduced, the abrasion of the scraper is reduced, the running efficiency of equipment is effectively improved, the product quality is improved, and meanwhile, the rolling phenomenon of tipping paper after scraping is effectively avoided.

After transformation, product quality defects such as cigarette bubble wrinkling, air leakage, mouth drop and the like caused by poor paper scraping are greatly reduced, the product quality is improved, and the hidden trouble of equipment is eliminated.

Although specific embodiments of the present application have been described in detail by way of example, it will be appreciated by those skilled in the art that the above examples are for illustration only and are not intended to limit the scope of the present application. It will be appreciated by those skilled in the art that modifications may be made to the above embodiments without departing from the scope and spirit of the present application. The scope of the application is defined by the appended claims.
