Description

Technical Field

[0001] The invention relates to material granulation, in particular to a full-automatic granulation machine. Background Art

[0002] Granulation equipment is a kind of equipment that prepares cotton, polyester and other materials into particles, generally including one-step granulation equipment and two-step granulation equipment.

[0003] The related one-step pelletizing equipment generally uses high-speed rotating blades to break up the materials and manually add water to form particles. Materials such as cotton and polyester are generally in a loose state and in the form of long strips, so they can only be fed manually. When rotating at high speed, the strip materials can easily be cut quickly and injure the workers, which places high demands on the workers' operation. In addition, it is necessary to rely on manual judgment on the time and amount of water addition, which further places high demands on the workers' operation.

[0004] The related two-step pelletizing equipment generally first uses a crushing device to crush the particles, and then uses a pelletizing device to pelletize the particles. In addition, the crushing device and the molding device need to be transported through multiple conveying devices, which easily leads to a large footprint of the equipment. At the same time, the installation and debugging performance of functional components such as the crushing device and the pelletizing device of the related two-step pelletizing equipment is poor.

[0053] The shell 1 is used to contain materials. In order to facilitate the installation and debugging of the crushing and conveying components 3, the granulation components 4, etc. in the shell 1, the shell 1 includes an upper shell 11 and a lower shell 12 that are detachably connected to each other; the feed port 13 is used for feeding, and the discharge port 14 is used for discharging. In order to reduce the height of the fully automatic granulator of the present application, the feed port 13 can be arranged at the upper end of the shell 1, and the discharge port 14 can be arranged at the front end of the shell 1, that is, the feed port 13 and the discharge port 14 are respectively located at the non-corresponding two ends of the shell 1; the driving shaft of the driving component 2 is used to drive at least part of the crushing and conveying component 3 and at least part of the granulation component 4 to rotate, and the driving component 2 can specifically include a motor 21, a reducer 22, etc.; the crushing and conveying component 3 is used to enable the material to be crushed and moved forward; the granulation component 4 is used to granulate the crushed material.

[0056] Specifically, the dynamic friction disk 411 is used to carry a plurality of first movable knives 412, a plurality of first grooves 413, etc. In order to increase the corresponding area of ​​the dynamic friction disk 411 and the fixed knife assembly 42, the shape of the dynamic friction disk 411 is preferably a truncated cone; the plurality of first movable knives 412 cooperate with the fixed knife assembly 42 to continue to shear and extrude the crushed material, so as to facilitate the plasticization of the crushed material. The number of the plurality of first movable knives 412 is not limited. The plurality of first movable knives 412 are preferably evenly distributed along the circumference of the dynamic friction disk 411, and the plurality of first movable knives 412 are preferably detachably connected to the dynamic friction disk 411 through fasteners; the plurality of first grooves 413 are convenient for increasing the friction force between the crushed material and the dynamic friction disk 411, so as to facilitate the crushed material to rotate with the dynamic friction disk 411.

The number of the plurality of first grooves 413 is not limited.

[0057] Further, such as Figure 4The fixed knife assembly 42 includes: a static friction disk 421 connected to the shell 1; a plurality of first fixed knives 422 that are detachably connected to one end of the static friction disk 421; a plurality of second grooves 423 that are all arranged at one end of the static friction disk 421; wherein the movable knife assembly 41 is rotatably sleeved in one end of the static friction disk 421.

The number of the plurality of first fixed knives 422 is not limited. The plurality of first fixed knives 422 are preferably evenly distributed along the circumference of the static friction disk 421. The plurality of first fixed knives 422 are preferably detachably connected to the static friction disk 421 by fasteners; the plurality of second grooves 423 facilitate increasing the friction between the crushed material and the static friction disk 421.
