[0029] Embodiment two: as Figure 1 Figure 7 As shown, the crushed material conveying mechanism includes two support plates 401 fixed on the inner side walls of the frame box two, a guide sliding groove 402 is formed on one side of the two support plates 401, a transmission rod 403 is movably connected between the two support plates 401 through bearings, a plurality of guide cylinders are fixedly connected to the outer side of the transmission rod 403, a guide sliding rod 404 is slidably connected in the guide cylinder, and one end of the guide sliding rod 404 outside the guide cylinder is fixedly connected to the bottom of the support frame.
[0030] The top end of the support frame is fixedly connected with an abutting bar one 405, the two ends of the abutting bar one 405 are rotatably connected with an abutting bar two 406, and a torsion spring is arranged at the rotatable connection of the abutting bar one 405 and the abutting bar two 406, and the abutting bar two 406 and the abutting bar one 405 are rotatably connected, so that the abutting bar two 406 can rotate smoothly without being disturbed by the top of the center processing table 3 during the rotation of the abutting bar one 405.
[0031] The two ends of the support frame are movably connected with pulleys 407 through bearings, and the pulleys 407 move in the guide sliding groove 402, a motor for driving the transmission rod 403 to rotate is fixedly installed outside the frame box two, a lifting push cylinder 7 is fixedly installed in the center processing table 3, a machine housing is fixedly installed at the top of the lifting push cylinder 7, and an electric cutting knife 8 is installed in the machine housing. Figure 5 As shown, the electric cutting knife 8 is composed of a plurality of blades and is arranged in a spaced manner with the abutting bar one 405, so as to realize the slitting cutting of the paperboard, and a plurality of cutting grooves 6 matched with the electric cutting knife 8 are formed through the top of the center processing table 3.
[0032] The inside of the conveyor cylinder 1 is equipped with a spiral blade 9, such as Figure 1 As shown, a drive motor for driving the spiral blade 9 to rotate is installed at the end of the conveying cylinder 1 away from the partition 10, and the partition 10 is fixedly installed at the discharge end of the conveying cylinder 1. Multiple sets of discharge slots 11 are arranged in a ring array on the outer side of the partition 10 with the center of the spiral blade 9 as the center. A rotary cutter 12 is movably connected to one side of the partition 10 through a bearing, and a motor for rotating the rotary cutter 12 is installed on the other side of the partition 10.
[0033] In the specific setup, the waste cardboard box, after being squeezed and formed into cardboard, is pushed to the top of the cutting groove 6. At this time, the motor drives the transmission rod 403 to rotate, and drives the pulley 407 to slide in the guide groove 402 through the guide cylinder, guide rod 404 and support frame. The guide groove 402 is shaped as follows: Figure 3 As shown, during the process of the pulley 407 moving from the top of the guide groove 402 to the bottom horizontal position, the first abutment bar 405 and the second abutment bar 406 first press against the top of the cardboard and slide horizontally along the top of the central processing table 3. During the passive horizontal sliding of the cardboard, the lifting cylinder 7 drives the electric cutting blade 8 to rise and extend it from the top of the cutting groove 6. The cardboard is slit and cut under the action of the first abutment bar 405, the second abutment bar 406 and the electric cutting blade 8 until the cutting is completed. At this time, the first abutment bar 405 and the second abutment bar 406 are disengaged from the cardboard, and the electric cutting blade 8 retracts back to below the horizontal level of the cutting groove 6.
[0034] After the cardboard is cut, the subsequent waste cardboard boxes are compressed and pushed to the top of the central processing table 3 with the cutting groove 6 under the action of the push plate 503 to wait for cutting. The cut cardboard is pushed into the conveying cylinder 1 through the feeding frame 2 by the subsequent cardboard. The spiral blade 9 conveys and squeezes the paper strips in the conveying cylinder 1, so that the cardboard at the rear end of the conveying cylinder 1 is conveyed to the front end. During the conveying process, the spiral blade 9 will further shred the paper strips into pieces. It should be explained here that the waste cardboard boxes are moistened before being squeezed to facilitate the shaping and crushing of the cardboard, and at the same time, it can further reduce the generation of debris particles.
[0035] As paper blocks accumulate at the front end of the conveyor cylinder 1, they are squeezed out from the discharge trough 11 outside the partition 10. The rotary cutter 12 continuously shreds the extruded paper material under the action of the motor. A collection box for collecting the shredded material is provided below the partition 10.
