An extrusion machine with an adaptive locking mechanism

Abstract

The invention relates to an extruder with an adaptive locking mechanism, comprising a first hydraulic cylinder, a second hydraulic cylinder, a lower pressing block and a die cavity, the side of the die cavity is connected to the output of the first hydraulic cylinder The upper side of the mold cavity is provided with a lower pressing block, the upper end surface of the lower pressing block is connected with the connecting rod of the second hydraulic cylinder, and it is characterized in that it also includes a locking cylinder, a first locking shaft and the second locking shaft, the lower end surface of the first locking shaft is connected with the lower pressure block, the upper end surface of the first locking shaft is in contact with the inclined surface of the second locking shaft, and the second locking shaft The side of the shaft is connected with the locking cylinder. The beneficial effect of the present invention is that: when the first hydraulic cylinder compresses the sawdust in the extrusion die cavity, the wooden block gives an upward force to the lower pressing block, and this force will cause the left end of the lower pressing block to tilt upward, because it is different from the The first locking shaft connected to the lower pressing block is pushed down by the second locking shaft moved by the locking cylinder, so the lower pressing block can not tilt.

Description

technical field [0001] The invention relates to an extrusion machine, in particular to an extrusion machine with a locking mechanism, and belongs to the technical field of extrusion equipment. Background technique [0002] It is impossible to avoid the inclination of the lower briquetting block during the extruding process of existing extruders both at home and abroad at present, and the current general practice is to increase the length of the lower briquetting block to reduce the inclination angle of the lower briquetting block. This approach has the following disadvantages: first, it increases the manufacturing cost of the equipment, and second, it cannot essentially solve the problems caused by the inclination of the lower pressing block, which will cause damage to the equipment to a certain extent, and will also cause damage to the equipment. Deform and crack the extruded wood block, reducing the surface quality of the wood block. Contents of the invention [0003] T...
