The upper limit tooth 8 is arranged in front of the lower limit tooth 12, and the distance between the upper limit tooth 8 and the lower limit tooth 12 can be adjusted by the upper connecting rod 6 and the lower connecting rod 13, so as to facilitate orderly, controllable and rapid loading;

[0029] An air pump 15 is fixedly installed at the inner end of the filter box 3, a connecting pipe 18 is fixedly installed at the upper end of the filter box 3, an air suction port 17 is fixedly installed at the upper end of the connecting pipe 18 at an equal distance, and the upper end of the air suction port 17 is fixedly installed at the lower end of the peeling machine body 14. A filter plate 16 is fixedly installed at the inner end of the filter box 3 to accelerate air flow to achieve cooling and facilitate the removal of powder generated during processing.

[0030] Specific working principle:

[0031] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, when the peeling machine for polymer material production is used, the polymer material to be peeled is quantitatively placed on the unloading slope 1 for loading and peeling. When loading, under the inclined slope of the unloading slope 1, the polymer material rolls to the rear side of the upper limit tooth 8, and the upper limit tooth 8 intercepts the material. When loading, the output shaft of the servo motor 2 drives the eccentric wheel 9 to rotate. When the eccentric wheel 9 rotates in the long radius direction to contact the bottom plate 10, it drives the bottom plate 10 and the lower side cross bar 11 to move upward, so that the linkage rod 5 rotates upward with the connection point with the unloading slope 1 as the axis. Then, when the linkage rod 5 rotates upward, the linkage rod 5 drives the upper side limit tooth 8 to be lifted up through the upper connecting rod 6 and the upper side cross bar 7. The polymer material on the rear side of the upper side limit tooth 8 loses the obstruction and rolls downward to realize loading. When the upper side limit tooth 8 is lifted up and released, the lower side limit tooth 12 is also The lower cross bar 11 is driven to lift up. Because the polymer material is cylindrical for peeling, when the upper limit tooth 8 is lifted, the lower limit tooth 12 just moves upward from between the two groups of polymer materials to prevent the polymer material on the rear side from rolling forward. Then the servo motor 2 drives the eccentric wheel 9 to rotate to a short radius and contact the bottom plate 10, and the upper limit tooth 8 falls to intercept the polymer material on the rear side. This reciprocating process is used to achieve orderly and rapid feeding. When the peeling machine body 14 peels the polymer material, the vacuum pump 15 at the inner end of the filter box 3 extracts the air on the inner and upper sides of the peeling machine body 14 through the connecting pipe 18 and the vacuum port 17, and then discharges it after being filtered by the filter plate 16 to achieve cooling and dust removal. The above completes a series of operations of the peeling machine for polymer material production. The content not described in detail in this description belongs to the prior art known to professional and technical personnel in this field.
