An easy-to-replace straw briquette forming mechanism

Abstract

The invention discloses a straw briquette forming mechanism convenient to replace. The straw briquette forming mechanism convenient to replace comprises a ring die 1 and planetary pressing wheels 2 arranged in the ring die 1. Inner teeth 3 are evenly distributed on the inner-diameter portion of the ring die 1. Outer teeth 4 are evenly distributed on the outer-diameter portions of the planetary pressing wheels 2. The inner teeth 3 are not engaged with the 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. Radial extrusion holes 5 are formed between every two adjacent inner teeth 3. 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. An annular installing and positioning boss 6 is arranged below the ring die 1, and the outer diameter of the annular installing and positioning boss 6 is the same as that of the ring die 1. According to the straw briquette forming mechanism convenient to replace, the ring die are not engaged with the planetary pressing wheels under the condition that no material exists; when materials enter the space between the ring die and the planetary pressing wheels, 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 smoothly extruded to be formed easily.

Description

technical field [0001] The invention relates to the technical field of straw briquette processing, in particular to an easy-to-replace straw briquette forming mechanism. 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 direction, which i...

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
