Problems solved by technology

[0003] However, in the existing mechanical extrusion mechanism, most of the extrusion pushers in the extrusion process do not have the function of cushioning, and it is easy to cause excessive extrusion of the product due to excessive extrusion force, which greatly reduces the product quality. It is also prone to excessive and unstable extrusion force, and it is difficult to ensure the normal and stable operation of the entire mechanical extrusion mechanism

Abstract

The invention discloses a mechanical extrusion mechanism which comprises an operation table. Two extrusion heads used for extruding materials are movably installed above the operation table, fixing bases fixedly installed on the operation table are arranged at the sides, away from each other, of the two extrusion heads, and grooves are formed in the sides, close to each other, of the two fixing bases; and symmetrically-arranged fixing blocks are fixedly installed at groove openings of the grooves, and fixing rods are fixedly connected between the fixing blocks and the inner walls of the sides,away from the groove openings, of the grooves. The mechanical extrusion mechanism has a good buffering function, the phenomenon that a material product is excessively extruded and formed due to the fact that the extrusion force of the extrusion heads is too large is avoided, the product quality is greatly guaranteed, instability in the extrusion process can be greatly reduced, it is guaranteed that the whole mechanical extrusion mechanism can work normally and stably, it is guaranteed that the safety of the materials in the extrusion process is higher, and the use requirements of people are met.

Description

technical field [0001] The invention relates to the field of mechanical technology, in particular to a mechanical extrusion mechanism. Background technique [0002] At present, in the biomass extrusion production process of biomass extruders, in order to ensure the stability of extrusion molding, it is necessary to ensure the stability of the internal pressure of the die cavity of the extruder, and the stability of the internal pressure of the die cavity is implemented in the specific structure. The size of the extrusion channel of the finger cavity is fixed, and the size of the extrusion channel corresponds to different raw materials one by one. For example, the existing patent No. CN108705803A discloses a mechanical extruder, which includes a silo, a mold cavity, a push head and an adjustment mechanism. The adjustment mechanism includes a bead, a pressure rod, and an adjustment cylinder. At the mouth, there is an extrusion channel in the mold cavity, and the bead is arran...
