Synchronous gap adjusting and locking mechanism of particle molding machine

Abstract

The invention provides a synchronous gap adjusting and locking mechanism of a particle molding machine. The synchronous gap adjusting and locking mechanism comprises a molding cavity upper cover plate with a feeding hole, a molding cavity lower cover plate, a ring mold, a pressing roller assembly and a discharging hole, and is characterized in that the pressing roller assembly is vertically mounted in a molding cavity; a wedge-shaped compression region is formed between the inner surface of the ring mold and the surface of the pressing roller; two shaft ends of the pressing roller are matched with eccentric shaft seats through sliding bearings; the eccentric shaft seats are matched with mounting holes of the upper and lower cover plates through external cylindrical surfaces of the eccentric shaft seats; the upper and lower eccentric shaft seats are connected through a connecting plate; an eccentric structure is formed by the eccentric shaft seats, and the mounting holes of the molding cavity upper cover plate and the molding cavity lower cover plate; and the eccentric shaft seats are connected through a gap adjusting positioning assembly. With the adoption of the synchronous gap adjusting and locking mechanism of the particle molding machine, the gap between the mold and the roller is convenient to adjust, the adjustment precision is high, the service life of the equipment is prolonged and the production cost is reduced.

[0002] The gap between the ring die and the pressure roller of the mold roller extrusion biomass pellet fuel molding machine has an important influence on the working performance of the pellet molding machine. Generally, the pressure roller shaft is processed into an eccentric type, and the ring die and the pressure roller are changed by rotating the eccentric shaft. This method is convenient to adjust the gap, but it is difficult to ensure the positional relationship between the eccentric shaft and the ring die. When the biomass is compressed, the end side of the eccentric shaft jumps a lot, which makes the axial gap consistency of the ring molding roller poor.

When the straight-shaft pressure roller shaft is used to cooperate with the ring die, if the two shaft ends are matched with the corresponding fixed mounting holes, the gap between the mold rolls cannot be changed; The position is locked after adjusting the gap at each end separately, the adjustment operation is complicated and the position accuracy retention ability is poor

After the gap is adjusted, the pressure roller assembly needs to be positioned to ensure a given gap size. The eccentric pressure roller shaft generally passes through one end of the claw, and the screw is used to withstand the end face of the claw. This positioning method applies the eccentric force of the pressure roller to the molding cavity. One side of the closed plate is easy to deform the plate, affecting the positioning accuracy of the pressure roller shaft, reducing the life of the forming mold and pressure roller, and increasing the production cost
