Description

Technical Field

[0001] The utility model relates to the technical field of transparent pulp processing, in particular to a transparent pulp raw material grinding device. Background Art

[0002] As the name implies, transparent glue refers to an adhesive with a transparent texture and bright color. Transparent glue is generally widely used and can be used to stick various types of materials, such as paper, wood, film, etc. In addition, transparent glue can also be used to make various types of crafts, handicrafts and small daily necessities. The main raw material of transparent glue is polyurethane. Polyurethane, also known as PU, is a high-performance, high-toughness elastomer obtained by reacting raw materials such as polyester and polyether. After grinding polyurethane, translucent or transparent colors can be obtained. According to the processing needs, polyurethane can be made into different forms such as granules and powders.

[0003] In the prior art, after grinding the transparent pulp raw material, it is necessary to perform a certain screening process on it to ensure that the grinding material particles are uniform, so as to improve the yield of transparent pulp production and processing. However, since the sieve holes for screening the transparent pulp raw material are generally small in diameter, it is easy to cause the grinding material to be blocked during screening. Therefore, in order to solve this problem, we propose a transparent pulp raw material grinding device. Utility Model Content

Through the arrangement of the frustum body 3, the transparent pulp raw material entering the grinding box 1 can all roll down to between the outer wall of the grinding ring 4 and the inner wall of the grinding box 1, so as to avoid the transparent pulp raw material falling on the surface of the rotating plate 16 and being unable to be ground;

[0023] Reference Figure 3 and Figure 4 The top and bottom ends of the screen plate 14 are both installed with dredging components, and the dredging components include a rotating ring 18 rotatably installed on the top and bottom ends of the screen plate 14, and the end of the rotating ring 18 away from the screen plate 14 is fixedly connected with a driven gear ring 19, and the rotating rod 17 passes through the rotating ring 18 and the driven gear ring 19, and the circumferential outer wall of the rotating ring 18 is fixedly installed with dredging plates 13 distributed in a ring array, and the dredging plate 13 is installed with dredging brushes distributed in a linear array along its length direction on one side of the dredging plate 13 close to the screen plate 14, and the dredging brushes can effectively improve the efficiency of the dredging plate 13 in dredging the sieve holes on the screen plate 14.

[0024] Reference Figure 3 and Figure 4 A driving assembly for driving a driven gear ring 19 to rotate is installed on the grinding box 1, and the driving assembly includes a bracket 6 fixedly installed on the outer wall of the grinding box 1, and a reciprocating rod 7 is slidably installed on the bracket 6, and a movable plate 8 is fixedly connected to the end of the reciprocating rod 7 away from the grinding box 1, and a driving plate 19 and a driving plate 2 10 are fixedly installed on the side of the movable plate 8 close to the grinding box 1, and the driving plates 19 and 10 slide through the circumferential side wall of the grinding box 1, and the driving plates 19 and 10 are both installed with driving tooth blocks meshing with the driven gear ring 19, and the driving plates 19 and 10 drive the driven gear rings 19 at the top and bottom ends of the screening plate 2 14 to rotate in opposite directions.

[0026] Working principle: When grinding the transparent slurry raw material, the transparent slurry raw material is first poured into the grinding box 1, and the transparent slurry raw material is made to fall between the grinding ring 4 and the inner wall of the grinding box 1 through the truncated cone 3, and the rotating rod 17 is driven by the driving motor 12 to rotate, and the rotating rod 17 drives the rotating plate 16 to rotate eccentrically, so that the grinding ring 4 is driven by the rotating plate 16 to be in inscribed contact with different positions of the inner wall of the grinding box 1, thereby grinding the transparent slurry raw material between the grinding ring 4 and the inner wall of the grinding box 1, and the ground raw material falls through the large-aperture sieve holes of the screening plate 1 2 to the plate surface of the screening plate 2 14 for further screening.

[0027] Since the aperture of the screening plate 2 14 is relatively small and has not been blocked, the grinding ring 4 can drive the swing rod 5 to swing while the grinding ring 4 moves, so that the swing rod 5 slides inside the swing column 15, and the swing rod 5 drives the reciprocating rod 7 to reciprocate in the horizontal direction. At the same time, the reciprocating rod 7 drives the movable plate 8, the driving plate 1 9 and the driving plate 2 10 to reciprocate as a whole, and then the driving tooth blocks on the driving plate 1 9 and the driving plate 2 10 engage with the driven gear ring 19, so that the two driven gear rings 19 can drive the rotating ring 18 and the two groups of dredging plates 13 to rotate in opposite directions, so as to effectively dredge the sieve holes on the screening plate 2 14 and avoid blockage.
