Fig. 3 is a partially enlarged view of the improved structure of the scraper blade according to the present invention.
Detailed Description
Referring to fig. 1-3, the present invention provides an improved doctor blade structure, comprising: axle sleeve 1, with 1 fixed connection's of axle sleeve mounting panel 2 and be located the scraper 3 on mounting panel 2, wherein:
the cutting edge of the scraper 3 is serrated, the serrated structure makes the material fragile, and is suitable for the material to be sticky and hard, and the cutting edge surface of the scraper 3 facing the scraping position is an inclined surface which is inclined from one side of the scraper 3 to the other side (namely, inclined in the thickness direction, as shown in fig. 3), so that the cutting edge enters in obliquely, the resistance is reduced, and the purpose of smooth cutting is achieved.
In addition, in the embodiment, the mounting plate 2 is opposite to the shaft sleeve 1, a material guide plate 5 which is arranged on one side of the mounting plate 2 along the height direction of the mounting plate 2 and forms an included angle with the mounting plate 2 for fixing is arranged between the mounting plate 2 and the shaft sleeve 1, and the included angle between the material guide plate 5 and the mounting plate 2 is an acute angle, a right angle or an obtuse angle; the scraper 3 is positioned at one side of the material guide plate 5 and arranged along the side edge of the mounting plate 2 in the height direction, so that the scraped materials flow down from the discharge port of the rotary drum under the blocking and flow guiding effects of the flow guide plate 5. In addition, this embodiment has still set up striker plate 6 at the top that mounting panel 2 is close to axle sleeve 1 one side to prevent the scraping process, the material phenomenon of turning over on.
In this embodiment, the mounting plate 2 is connected with the shaft sleeve 1 through a connecting rod, and a sweeping plate 7 which is opposite to the mounting plate 2 and fixed with the connecting rod is arranged between the mounting plate 2 and the shaft sleeve 1. In the scraping process, the material at the bottom of the rotary drum is cleaned up by the material sweeping plate 7 and is swept to the discharge hole to flow out. And in order to enhance the cleaning effect, specifically: the sweeping plate 7 and the mounting plate 2 are arranged at an acute angle.
In this embodiment, the specific mounting structure of the rest mounting plates 2 of the scraper 3 includes the following two types:
example 1
The doctor blade 3 is formed by a plurality of blade combinations arranged in sequence along the height direction of the mounting plate 2, so that each blade in the doctor blade 3 can be replaced individually.
In addition, the mounting plate 2 is made of 2205 stainless steel materials through laser cutting processing, the verticality of the product can be effectively guaranteed, the scraper 2 is made of tungsten steel alloy, the wear resistance and the toughness are good, and the service life of the product is effectively prolonged.
Example 2
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
