As shown in fig. 4-8, the paper pressing device 80 includes a vertical driving assembly, a swinging driving assembly 82, a sleeve 84, a swing link guide 85, a linear slider 86, a rolled sheet-shaped steel bar 87 and a rotating shaft 88, wherein a power end of the vertical driving assembly is connected with the swinging driving assembly 82, the sleeve 84 is vertically disposed, an upper end of the sleeve 84 is fixed at the swinging driving assembly 82, the rotating shaft 88 is rotatably installed in the sleeve 84, the sleeve 84 and the rotating shaft 88 are rotatably connected through a sleeve bearing 841, a power end of the swinging driving assembly 82 is connected with an upper end of the rotating shaft 88, a lower end of the rotating shaft 88 is connected with a first end of the swing link guide 85, the swing link guide 85 is horizontally disposed, the swinging driving assembly 82 can drive the rotating shaft 88 to rotate in the sleeve 84 and drive the swing link guide 85 to rotate along an axis of the rotating shaft 88, the linear slider 86 is installed in the swing link guide 85 and can linearly slide along the swing link guide 85, a top of the linear slider 86 is located outside a top surface of the swing link guide 85, the rolled sheet-shaped steel bar 87 is sleeved outside the sleeve 84 and adjacent to the swing link guide 85, an inner ring end of the rolled sheet-shaped steel bar 87 is fixedly connected to the sleeve 84, and an outer ring end of the linear slider 86 hinged with the linear slider 86; the swing drive assembly 82 can drive the swing rod guide rail 85 to rotate and drive the rolled sheet steel bar 87 to roll or expand through the slide block, so that the outer diameter of the rolled sheet steel bar 87 is expanded or reduced.

When the paper pressing device 80 needs to work, the linear driving device 81 drives the rotary pendulum driving assembly 82, the sleeve 84, the pendulum rod guide rail 85, the rolled sheet steel bar 87 and the rotating shaft 88 to descend simultaneously, the guide upright post 83 plays a role of guiding the rotary pendulum driving assembly 82, the rolled sheet steel bar 87 is in a rolling state, as shown in fig. 8, the rolled sheet steel bar 87 is in a first state 87A, and when in the first state 87A, the diameter of the rolled sheet steel bar 87 is smaller. After the rolled sheet steel bar 87 enters the material containing barrel 71, the lower end of the rolled sheet steel bar 87 and the bottom surface of the swing rod guide rail 85 press the packing paper at the bottom wall of the inner side of the material containing barrel 71.

The swing driving assembly 82 rotates, and at this time, the rotating shaft 88 rotates in the sleeve 84, the sleeve 84 is not rotatable, as shown in fig. 8, the rotating shaft 88 drives the swing link guide 85 to rotate clockwise, and the rolled sheet steel bar 87 is gradually unwound and forms the second state 87B. In this process, the outer end of the wind-up sheet steel bar 87 has a tendency to gradually move outward, so that the linear slider 86 hinged to the outer end of the wind-up sheet steel bar 87 also moves outward in the swing link guide 85.

After the linear slider 86 moves to the end of the swing link guide rail 85, the distance between the linear slider 86 and the lower end of the rotating shaft 88 is unchanged, but the outer diameter of the rolled sheet steel bar 87 continuously expands to form a third state 87C as shown in fig. 8 after the rotating shaft 88 is continuously rotated by a small amplitude, and at the moment, the outer diameter of the rolled sheet steel bar 87 becomes cylindrical, so that the packing paper can be extruded and attached to the inner annular wall of the material containing barrel 71.

Then, the rotating shaft 88 is rotated counterclockwise, and after the rolled sheet steel strip 87 retracts to the first state 87A, the linear driving device 81 drives the rolled sheet steel strip 87 to withdraw from the packing paper and the material containing barrel 71, so that the laying of the packing paper is completed, and the subsequent discharging and compacting processes are facilitated. In the process, even if the packaging paper has partial folds, the subsequent discharging and compacting processes are not influenced.

This reducing mechanism still attaches packing briquetting part, and wherein press paper device 80 can impress packing paper in the feed cylinder, through the tight slice billet 87 outside end pivoted mode adjustment of tight slice billet 87 external diameter, can press packing paper into the feed cylinder, can be with packing paper again in the complete general book of feed cylinder inner wall and attached at the feed cylinder inner wall, the structure is ingenious, low cost has the advantage that maintenance-free efficiency is high concurrently.

The foregoing is only a preferred embodiment of the present invention, and many variations can be made in the specific embodiments and applications of the present invention by those skilled in the art without departing from the spirit of the present invention.
