Embodiment

[0047] Such as Figure 3-7As shown, the concave-convex pattern roller-to-extrusion compression molding particle mechanism includes a headstock 11 and a transmission extrusion mechanism arranged on the headstock. Transmission shaft 14, the driving gear 18 that is located on the main transmission shaft, the driven gear 16 that meshes with the driving gear, the driven gear is provided with the driven shaft 15. The machine head base includes a base and a stand, the base is provided with screw holes, and the two sides of the stand are provided with partitions.

[0048] The transmission extrusion mechanism also includes a pair of extrusion rollers 10 that are fixedly connected to one end of the main transmission shaft 14 and the driven shaft 15 respectively and are used to extrude the compressed material. The rollers of the extrusion rollers are hollow rollers, and the rollers A plurality of die holes 12 are arranged on the cylinder, and the die holes run through the inner and oute...

Abstract

The invention discloses a particle extruding and forming mechanism provided with concave-convex pattern roller pairs. The particle extruding and forming mechanism comprises a handpiece base, a transmission mechanism and an extruding mechanism, wherein the transmission mechanism and the extruding mechanism are arranged on the handpiece base. The extruding mechanism comprises a pair of extruding rollers used for extruding raw materials. The transmission mechanism is connected with the extruding rollers and drives the extruding rollers to move in the opposite directions. Drums of the extruding rollers are hollow drums. A plurality of rows of protruding structures extending in the longitudinal directions of the drums are uniformly arranged outside the ends, connected with the transmission mechanism, of the two drums. The protruding structures in every two adjacent rows make mutual contact. Each protruding structure in each row comprises a plurality of protruding tops equally spaced. The protruding tops form the outer surfaces of the extruding rollers together. A die hole is formed in a depression between every two protruding tops. According to the particle extruding and forming mechanism, power consumption is small, the defect that the size of particles is limited is overcome, the strength of space gaps formed by the protruding tops is sufficient, the technological problem of hole wall cracking caused by stress concentration in the heat treatment process is solved, the service life of the extruding rollers is prolonged, and cost is saved.

Description

technical field [0001] The invention relates to a concave-convex pattern roller-to-extrusion compression molding particle mechanism, which belongs to the field of mechanical equipment. Background technique [0002] Pellet molding mainly refers to the molding of various biomass pellets, such as pellet feed, biomass pellet fuel, etc. [0003] At present, my country's biomass pellets are mainly formed by flat die and ring die. In the past two years, there have been mechanical stamping and curved tooth-roll extrusion. Several extrusion molding methods are now described as follows: [0004] A. The flat die and the ring die are actually the same, but the form of the template is different, and the direction of the material is different. Such as figure 1 with figure 2 Shown: [0005] Flat die extrusion is driven by the rotating horizontal template to drive the pressure roller to realize the opposite direction rotation of the template and the pressure roller. Through the fricti...
