The track groove 11a is formed by a horizontal portion and an arc portion communicating with each other, wherein the arc portion has a radius equal to the distance from the nose bar 6a to the center of the left gear 6.
In the initial state, the cutting blade 21 and the holder 20 are located at the front position on the table 1, and the protruding rod 6a is located at the upper limit position on the left gear 6.
Before the use, the multilayer medical paper is only required to be aligned and arranged at the corners and then stacked at the upper end of the conveying belt 2, and the left end of the multilayer medical paper and the right end face of the cutting knife 21 are coplanar.
When the transmission gear is used, the motor 4 drives the incomplete gear 5 to rotate, so that the incomplete gear 5 can be respectively in alternate meshing transmission with the left gear 6 and the right gear 7.
When the incomplete gear 5 is in mesh transmission with the right gear 7, the belt wheel 25 rotates in the same direction with the right gear 7, so that the conveying belt 2 transmits the plurality of layers of medical papers to the left side, and a part of the left side of the plurality of layers of medical papers is transmitted to the collecting table 3.
When the incomplete gear 5 is in mesh transmission with the right gear 7, the left gear 6 can rotate one turn, so that cutting can be completed by performing the following four steps in sequence.
In the first step, when the left gear 6 rotates for the first 90 degrees, the middle of the protruding rod 6a can rotate to abut against the cross bar 12, and the rear end of the protruding rod 6a can rotate to the connection point where the horizontal part and the arc-shaped part of the track groove 11a are located on the left side.

In the second step, when the left gear 6 rotates by the second 90 degrees, the rear end of the protruding rod 6a slides in the left part inside the arc-shaped part of the track groove 11 a. In the whole rotation process, the booster plate 11 is static; the middle part of the convex rod 6a can extrude the cross rod 12 downwards, so that the rack 14 slides downwards and is compressed together with the cross rod 12, the transmission gear 15 and the lead screw 16 rotate anticlockwise under the meshing transmission of the gear and the rack, and the cutter handle 20 and the cutter 21 can slide from front to back under the transmission action of the lead screw nut, so that the pressing part of the multilayer medical paper can be cut, and the cutting smoothness is guaranteed while the one-time cutting is realized.
Third, when the left gear 6 is rotated by the third 90 degrees, the rear end of the nose bar 6a slides in the right part inside the arc-shaped part of the track groove 11a until the nose bar 6a slides to the point where the horizontal part and the arc-shaped part of the track groove 11a communicate with each other on the right side. In the whole rotation process, the booster plate 11 is static; the rack 14 and the cross bar 12 can slide upwards under the action of the elastic restoring force of the first spring 13 by the upward rotating movement of the middle part of the convex rod 6a, so that the transmission gear 15 and the lead screw 16 rotate clockwise, and the cutter handle 20 and the cutting knife 21 can slide forwards from the back, so that the reset after each cutting is realized.
Fourthly, when the left gear 6 is rotated by the fourth 90 degrees, the nose bar 6a slides leftward at the rear end at the horizontal portion of the track groove 11a to the middle position of the horizontal portion. During the whole rotation process, the assisting plate 11 and the lifting base 18 can slide upwards, that is, the pressing state of the pressing plate 22 on the multi-layer medical paper can be released, so that the multi-layer medical paper can be continuously transported and supplied leftwards for the part which is not divided.
Therefore, by sequentially executing the above four steps every time the transportation is stopped, the multi-layer medical paper can be divided smoothly.
