When the cutter 51 is transported by the first cutter transporting wheel 651 and discharged from the third groove 52 to pass through the cutter discharging opening 66, the third cutter transporting wheel 661 is started to enable the third cutter transporting wheel 661 to rotate, the power of the third cutter transporting wheel 661 can be provided by a motor, the cutter 51 is assisted to be discharged from the cutter discharging opening 66 through the rotation of the third cutter transporting wheel 661, the condition that the cutter 51 cannot be discharged is avoided, the discharged cutter 51 falls to the cutter receiving frame 21 later, the cutter 51 is stored, and the cutter is convenient for staff to process.
The specific working procedure is as follows:
placing a plurality of brand-new cutting knives 51 into the knife accommodating groove 61, enabling the cutting edge to be upward, and pressing the plurality of cutting knives 51 by a first spring 611 in the knife accommodating groove 61 in cooperation with the top plate 612; the staff can set a fixed time, so that the fixed time interval console 1 controls the first hydraulic rod 621 to shrink, the first hydraulic rod 621 shrinks to drive the rotating block 64 to move upwards, the cutting knife 51 participating in cutting work is limited under the extrusion of the first knife-carrying wheel 651 and then separated from the second groove 641, and it is worth noting that when the cutting knife 51 participates in cutting work, the rotating block 64 and the first block 5 are static, and the first block 5 and the support 4 are displaced up and down to complete cutting work; when the above-mentioned cutter 51 is separated from the second slot 641, the second motor 65 starts to drive the first cutter wheel 651 to rotate so that the cutter 51 contacted with the second motor is transported, the cutter 51 is then discharged from the cutter-discharging opening 66 through the third slot 52, the cutter-discharging opening 66 is arranged at one side of the support 4 far away from the console 1 (when the cutter needs to be replaced, the third slot 52 at the bottom of the first block 5 is controlled to be aligned with the cutter-discharging opening 66), the rotating block 64 continues to move upwards, when the cutter moves to the lower end of the second cutter 613, the cutter 51 enters the second slot 641 under the attraction of the permanent magnet 642, then the first hydraulic rod 621 controls the rotating block 64 to move downwards, the first stepping motor 63 is controlled to rotate when the first stepping motor 63 rotates only 180 degrees each time, the cutter 51 after the replacement is converted to the cutting edge downwards, then the rotating block 64 continues to move downwards so that the cutter 51 exposes the first block 5, the new cutter 51 continues to perform cutting operation, the second hydraulic rod 652 stretches and drives the second motor 65 to be close to or far away from the first cutter wheel 651, the second cutter wheel 651 can be easily moved between the first cutter wheel 51 and the second cutter wheel 651, and the second cutter wheel 651 can be easily controlled to move between the first cutter wheels 51 and the second cutter wheel 651 when the second cutter wheel is easily pressed; when the used cutting knife 51 is required to be pulled out of the second groove 641 or the first knife transporting wheel 651 is used for transporting the cutting knife 51, the second hydraulic rod 652 can be controlled to stretch to enable the first knife transporting wheel 651 to be close to each other, the cutting knife 51 is clamped, and friction between the first knife transporting wheel 651 and the cutting knife 51 is increased; so that the cutting knife 51 is pulled out from the second groove 641 more smoothly, or the first knife-transporting wheel 651 is more convenient for transporting the cutting knife 51.
