A molding mechanism that uses plant fibers to press large particles

Abstract

The invention discloses a forming mechanism for pressing plant fibers into large particles. The forming mechanism comprises a ring die 1 and planetary pressing wheels 2 arranged in the ring die 1. Quincunx inner teeth 3 are evenly distributed on the inner-diameter portion of the ring die 1. Quincunx outer teeth 4 are evenly distributed on the outer-diameter portions of the pressing wheels 2. The quincunx inner teeth 3 are not engaged with the quincunx outer teeth 4. The ring die 1 is fixed. The planetary pressing wheels 2 are driven through a planetary transmission mechanism to turn on the axes of the planetary pressing wheels 2 and to revolve around the ring die 1 at the same time. The ratio of the number of the teeth of the ring die 1 to the number of the teeth of each planetary pressing wheel 2 is equal to the transmission ratio of the planetary transmission mechanism. A group of radial extrusion holes 5 are evenly distributed between every two adjacent quincunx inner teeth 3. According to the forming mechanism for pressing the plant fibers into the large particles, the ring die are not engaged with the planetary pressing wheels under the condition that no material exists; after materials enter the forming mechanism, the ring die and the planetary pressing wheels are engaged under the action of the materials, flowing of the materials in the circumferential direction is reduced, flowing of the materials in the radial direction is strengthened, and the materials can be extruded easily for particle forming.

Description

technical field [0001] The invention relates to the technical field of plant fiber briquette forming, in particular to a forming mechanism for pressing large particles with plant fiber. Background technique [0002] The existing straw processing and forming mechanism is composed of a pressure wheel and a ring die. When the wheel revolves around the ring die driven by the transmission mechanism, because the outer teeth on the pressure wheel mesh with the inner teeth on the ring die, the pressure wheel is driven to rotate passively to extrude the material from the forming hole to complete the forming of the material. Regardless of whether the above-mentioned mechanism is idling or working with materials, the pressure wheel and the ring die are always in contact. On the one hand, the outer teeth of the pressure wheel and the inner teeth of the ring die wear quickly and the service life is short. On the other hand, it is easy to drive the material to flow in a circumferential di...

Problems solved by technology

Regardless of whether the above-mentioned mechanism is idling or working with materials, the pressure wheel and the ring die are always in contact. On the one hand, the outer teeth of the pressure wheel and the inner teeth of the ring die wear quickly and the service life is short. On the other hand, it is easy to drive the material to flow in a circumferential direction, which is not conducive The material is extruded smoothly
