Detailed Description
The technical scheme of the utility model is clearly and completely explained by combining the attached drawings.
As shown in fig. 1-2, a shape-preserving discharging device comprises a shape-preserving cavity 301, wherein the shape-preserving cavity 301 is a rectangular tubular structure with two open ends, and comprises an upper plate, a lower plate, a left plate and a right plate, and the front and the back of the shape-preserving cavity are open. A connecting flange 302 is arranged at the rear opening, namely the feeding end, of the die cavity and is used for being connected with a compression cavity of the previous compression process, and crushed straw blocks compressed in the compression cavity enter the shape-keeping cavity to keep the shape of a cuboid.
The middle parts of the upper plate and the lower plate of the protective cavity are both provided with an opening seam 3011 along the length direction, the opening seam completely divides the upper plate into two parts at the discharge end, the opening seam is blind at the feed end and is not communicated, a seam adjusting device 3012 is arranged at the opening seam close to the discharge end, a seam adjusting device is arranged at the seam of the upper plate and the lower plate, the seam adjusting device comprises a screw rod, the two ends of the screw rod are respectively and fixedly connected with the upper plate divided into two parts by the opening seam, the screw rod is provided with a plurality of nuts, the width of the opening seam can be adjusted by rotating the nuts, so that the inner diameter of the protective cavity is finely adjusted, the stress in a compression material block can be buffered, the friction resistance of the advancing material block is increased or reduced, and the material block can be smoothly output from the protective cavity.
The length measuring device is arranged at the opening seam 3011 of the upper plate of the shape keeping cavity and is a circumferential tooth-shaped length measuring wheel 303 which penetrates through the opening seam and extends into the shape keeping cavity, when a material block advances in the shape keeping cavity, the material block and teeth on the periphery of the length measuring wheel are in friction driving to rotate the length measuring wheel, and therefore the advancing length distance of the material block is calculated and sensed for control.
The corner sleeves 3053 with L-shaped sections are arranged on the four edges of the discharge end of the cavity, the corner sleeves are connected with the telescopic driving device and can reciprocate, and the corner sleeves extend out of the discharge end or retract into the four edges; the L-shaped lining 307 is fixedly connected to the inner side of the corner sleeve 3053, the lining 307 wraps the edge of the discharging end of the protective cavity and can slide along the edge, the friction coefficient of the lining with the edge is small, the corner sleeve 3053 is arranged on the outer side of the lining 307, the front end of the corner sleeve 3053 and the front end of the lining 307 are not aligned, the front end of the lining leads the front end of the corner sleeve, a front inclined oblique angle 3071 is arranged at the front end of the lining and is used for ensuring that films pre-wound on the four corner sleeves are inclined inwards, the films can be wound inside the front inclined angle, and when the material block is pushed out, the pre-wound films can be taken out.
