[0024] The working principle of the pulper for papermaking machinery with convenient feeding and discharging:
[0025] When pulping figure 1 As shown, the pulping cylinder 38 is at the uppermost end, the lower right vertical rod 371 is at the uppermost end, and the limiting insert 341 is at the lower end. At this time, the upper opening of the pulping cylinder 38 is closed by the upper closing seat. 38 is filled with waste paper, the pulping center column 22 rotates, and the pulping blade 23 shreds the paper;
[0026] After the paper shredding is completed, through the rotation of the lifting threaded rod 32, and the guiding action of the upper right vertical rod 35 and the lower right vertical rod 371, the pulping drum 38 is lowered to the lowest end as figure 2 As shown, at this time, the pulping drum 38 is located under the lower support plate 12, and the lifting support block 381 on the right is vertically sleeved on the lower right vertical rod 371, and then the lower right vertical rod 371 is lowered so that the connecting rod 372 Disengage from the connection slot 350, and at the same time, the limit pin 341 rises and inserts into the upper limit hole 3810, so that when the lifting threaded rod 32 rotates again, the pulping cylinder 38 will not fall and will only rotate with the lifting threaded rod 32. The opening of the upper end of the pulping drum 38 is exposed on the front side or the rear side of the frame 10, which facilitates the removal of pulp and the reinsertion of waste paper.
[0027] The above content is only the preferred embodiments of the present invention. For those of ordinary skill in the art, according to the ideas of the present invention, there will be changes in the specific embodiments and the scope of application. limits.
