Detailed Description

The present invention will be described in further detail with reference to the following embodiments, which are illustrated in the accompanying drawings.

In a first embodiment, referring to fig. 1, 2 and 3, a bale breaker includes an upper conveyor 1, a lower conveyor 2, a frame 3 and a cutter assembly 4, where the upper conveyor 1 includes a first driving roller 11 and a first driven roller 12 rotatably connected to the frame 3, the lower conveyor 2 includes a second driving roller 21 and a second driven roller 22 rotatably connected to the frame 3, the first driving roller 11 and the first driven roller 12 are provided with a plurality of annular steel wire ropes 5, the first driving roller 11 drives the first driven roller 12 to rotate through the annular steel wire ropes 5, the second driving roller 21 and the second driven roller 22 are also provided with a plurality of annular steel wire ropes 5, the second driving roller 21 drives the second driven roller 22 to rotate through the annular steel wire ropes 5, the cutter assembly 4 includes a plurality of cutters 41 installed below the lower conveyor 2, and a plurality of cutters 41 extend out between the annular steel wire ropes 5 of the two lower conveying devices 2 at intervals.

Referring to fig. 2 and 3, the first driven roller 12 is spaced apart from the second driven roller 22 by a distance greater than the opening distance of the first driving roller 11 and the second driving roller 21. Therefore, the distance between the upper conveying device 1 and the lower conveying device 2 is gradually reduced, and the material bag conveying process has a squeezing effect. In the present embodiment, the interval between the first driven roller 12 and the second driven roller 22 is 30 cm; the first drive roll 11 and the second drive roll 21 are spaced apart by a distance of 10 cm.

Referring to fig. 1, a placing platform 6 is arranged in front of the second driven roller 22 of the frame 3. The placement platform 6 can be welded to the frame 3, the placement platform 6 being mainly used for depositing bags of material.

Referring to fig. 1, the frame 3 has two power transmission rollers 7 at the rear of the second drive roller 21. The power transmission roller 7 is driven by a motor and is used for conveying the opened material bags out of the unpacking machine. The distance between the two power transmission rollers 7 was 3 cm.

Referring to fig. 1 and 2, the cutter assembly 4 further includes a mounting bracket 8 mounted on the frame 3, and the cutter 41 is fixed to the mounting bracket 8. The cutting knife assembly 4 is fixed on the mounting frame 8 in a bolt mounting mode, is vertically mounted upwards and extends out of the space between two adjacent annular steel wire ropes 5 of the lower conveying device 2.

The utility model discloses a first drive roll 11 and second drive roll 21 all drive through respective motor, because the utility model discloses need extrude the material bag, consequently can only transmit through wire rope 5, wire rope has certain elasticity, can extrude the material bag better. In use, for example, a 20kg additive material bag is placed on the wire rope 5 of the lower conveyor 2 from the gap between the first driven roller 12 and the second driven roller 22, the material bag moves along with the wire rope 5 by its own weight and friction, and when the material bag moves to the position of the cutter 41, the distance between the upper conveyor 1 and the lower conveyor 2 becomes smaller, so that the upper portion of the material bag also starts to contact the wire rope 5 of the upper conveyor. At this time, the material bag is cut by the cutting knife 41, the material starts to be discharged, the material falls from the space between the two rollers of the lower conveying device 2, the upper steel wire rope 5 and the lower steel wire rope 5 can gradually extrude the material bag along with the reduction of the distance between the upper conveying device 1 and the lower conveying device 2, the material in the material bag is fully extruded, and the empty bag is conveyed out of the bale breaker through the two power transmission rollers 7 without material residue.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, many modifications and improvements can be made without departing from the inventive concept, and all of them belong to the protection scope of the present invention.
