[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0027] Example

[0028] See also Figure 1 , Figure 2 , Figure 3 The utility model provides a technical solution of a scraper device for a mixing mill roller: the structure includes a scraper device body 1, the scraper device body 1 is arranged below the roller 2A on the mixing mill 2, such as Figure 1 As shown;

[0029] The scraper device body 1 comprises a scraper holder 11, and the scraper holder 11 has a protruding first connection portion 111 for providing a connection space and a rotation position;

[0030] The fixing plate 12 is provided with at least one second connecting portion 121 corresponding to the first connecting portion 111. The fixing plate 12 is rotatably arranged outside the scraper holder 11 through a rotating shaft passing through the first connecting portion 111 and the second connecting portion 121. The bottom end of the fixing plate 12 is provided with a second connecting portion 121 hingedly connected to the rotating shaft of the first connecting portion 111.

[0031] The scraper 13 is horizontally arranged at the front end of the scraper holder 11 relative to the ground. The scraper 13 is made of a material selected from high-carbon tool steel, plastic, alloy steel, and high-speed steel, and is manufactured by forging, casting, or machining.

[0032] The adjustment mechanism 14 is connected to the inner side of the fixing plate 12 and is used to adjust the movement angle of the scraper holder 11, and the angle is 15°-80°.

[0033] like Figure 2 , 3 As shown, in order to facilitate manual adjustment, the adjustment mechanism 14 includes an adjustment disk 141 rotatably arranged on the inner side of the fixed plate 12, and an operating rod 142, wherein the operating rod 142 is connected to the outer ring of the adjustment disk 141, and the adjustment disk 141 is provided with an eccentric shaft 143 rotatably connected to the inner side of the fixed plate 12 and a bolt hole 144, and a limiting bolt is screwed on the bolt hole 144 to be in close contact with the inner side of the fixed plate 12.

[0034] In order to act on the scraper holder 11 , the outer peripheral bottom surface of the regulating disk 141 contacts the top surface of the scraper holder 11 , so as to make the scraper holder 11 rotate accordingly when the regulating disk 141 rotates.

[0035] For easy assembly, the scraper holder 11 and the scraper 13 cooperate to form a U-shaped structure, and the top surface of the scraper holder 11 and the top surface of the fixing plate 12 have a curved surface for avoiding the roller of the mixing mill 2.

[0036] In order to adapt to different scraping angles, the blade of the scraper 13 is vertically upward or inclined upward.

[0037] In order to improve the firmness of the connection, the scraper 13 and the scraper holder 11 are connected by bolt fixing or welding.

[0038] In order to install the fixing plate 12 on the mixing mill 2 , at least one mounting hole is provided on the outer wall of the fixing plate 12 .

[0039] The use of an adjustment mechanism 14 that can manually adjust the scraping angle of the scraper holder 11 effectively improves the convenience of the scraping work of the mixing mill. When adjustment is needed, the limiting bolt is loosened so that the limiting bolt releases the restriction on the inner side of the fixed plate 12, and then the adjusting disk 141 is rotated by the operating rod 142. Under the positioning of the eccentric shaft 143 on the adjusting disk 141, the adjusting disk 141 rotates eccentrically to press the scraper holder 11 downward, so that the scraper holder 11 is swung up with the hinge point where the first connecting part 111 and the second connecting part 121 are connected as the center, driving the scraper 13 to adjust the angle.

[0040] Modifications of the embodiments of the present application

[0041] This variant is an automatically operated adjustment mechanism 14;

[0042] like Figure 4 , 5 As shown, in order to facilitate automatic adjustment, the adjustment mechanism 14 includes a drive cylinder fixing plate 145, a drive cylinder 146 with the output end facing downward, a first fixing block 147, and a second fixing block 148. The first fixing block 147 is arranged on the inner side of the drive cylinder fixing plate 145, and the lower end of the first fixing block 147 is provided with a third hinge seat 1471 hinged to the bottom outer wall of the drive cylinder 146. The second fixing block 148 is arranged at the rear end of the scraper holder 11, and the rear side of the second fixing block 148 is provided with a fourth hinge seat 1481 hinged to the output end of the drive cylinder 146.

[0043] In order to improve the driving efficiency, the driving cylinder is one of an electric cylinder, a hydraulic cylinder and a pneumatic cylinder;

[0044] Pneumatic cylinders, electric cylinders, and hydraulic cylinders are all actuators used to achieve linear motion;

[0045] Cylinder: uses the pressure of compressed air as the power source, and controls the linear reciprocating motion of the piston in the cylinder through the pneumatic system;

[0046] Electric cylinder: Also known as electric cylinder, it is a device that converts the rotary motion of a motor (such as a servo motor or a stepper motor) into linear motion through a lead screw. It has high motion accuracy and can flexibly adjust parameters such as position, speed and torque through programming;

[0047] Hydraulic cylinder: uses liquid (usually oil) as the working medium, and drives the piston to move linearly through the pressure provided by the hydraulic pump. The hydraulic system can generate large thrust or pull force and can maintain stable output;

[0048] Preferably an electric cylinder is used.

[0049] In order to bolt the first fixing block 147 and the second fixing block 148 to the inner side of the driving cylinder fixing plate 145 and the rear end of the scraper holder 11 respectively, a strip fixing hole 149 is provided on the first fixing block 147 and the second fixing block 148, and the strip fixing hole 149 is used to adjust the fixing position of the bolt.

[0050] The driving cylinder fixing plate 145 is fixed on the mixing mill 2 and is spaced above the scraper holder 11 .

[0051] An adjustment mechanism 14 that can automatically adjust the scraping angle of the scraper holder 11 is adopted to effectively improve the convenience of the scraping work of the open mill. When adjustment is needed, the control terminal on the open mill 2 controls the operation of the drive cylinder 146, and the output end of the drive cylinder 146 extends out, and the scraper holder 11 is pressed down through the second fixed block 148 and the fourth hinge seat 1481, so that the scraper holder 11 is swung up with the hinge point connected by the first connecting part 111 and the second connecting part 121 as the center, driving the scraper 13 to adjust the angle.
