The utility model provides a cutting knife set, wherein a preferable position rotating seat 1 can be lifted and rotated during cutting operation. The mechanism for lifting and rotating the device is not the scope of the utility model, but is preferably an (xyz) three-axis gantry, a fixed seat is arranged on the three-axis gantry, a (servo) motor is arranged on the fixed seat, and then an output shaft of the motor is connected with the rotating seat 1, so that the rotating seat 1 can be controlled to lift and rotate, and corresponding cut objects can be cut. It should also be appreciated that the control of the rotary seat 1 is not a claimed structure and will not be described in any detail herein.

In the cutting process, the bottom of the rolling cutter 4 is lower than the rotating seat 1, one side of the rolling cutter 4 is movably attached to the rotating seat 1, and the other side of the rolling cutter 4 is movably attached to the lifting column 5, so that the rolling cutter 4 and the rotating seat 1 can have sufficient relative position stability, and meanwhile, the rolling cutter 4 is movably sleeved on the supporting column 2, so that the rolling cutter 4 can rotationally cut, and the cutting process can be normally carried out. Meanwhile, as the lifting column 5 is continuously subjected to downward elasticity of the elastic piece 7, the cross rod body 6 is abutted against the top of the supporting column 2, and therefore the position stability of the rolling cutter 4 is ensured.

Then when the rolling cutter 4 is replaced or the rolling cutter 4 is taken down for polishing, the lifting column 5 is lifted upwards through the transverse rod body 6, the lifting column 5 is separated from the support column 2, and after the lifting column 5 moves to a position which does not influence the movement of the rolling cutter 4, the rolling cutter 4 is directly taken down from the support column 2. After the rolling cutter 4 is replaced or polished, the rolling cutter 4 is directly sleeved on the support column 2, then the lifting column 5 passes through the limiting hole 3 from top to bottom, and the transverse rod body 6 is abutted to the top of the support column 2, so that the limiting of the rolling cutter 4 can be completed, the device is simple and convenient, and the efficiency is improved.

In which, furthermore, the conventional limiting of the rolling cutter 4 by means of a bolt involves the risk of loosening or even falling off with increasing use time. However, the lifting column 5 in the present application is continuously subjected to downward elastic force, so that the position of the lifting column 5 can be maintained and the rolling blade 4 is prevented from loosening or sliding off regardless of use.

In actual use, the top of the elastic piece 7 is abutted against the inner wall of the top of the lifting groove, the bottom is abutted against the top of the lifting table 9, and meanwhile, the lifting table 9 cannot continuously move downwards because the transverse rod body 6 is abutted against the supporting column 2 in the vertical direction, so that the lifting column 5 can stably limit the outer side of the rolling cutter 4.

When the rolling cutter 4 needs to be replaced or polished, a worker only needs to manually move the transverse rod body 6 upwards, and the lifting column 5, the rotating member 12, the rotating column 11, the cover plate 10 and the lifting table 9 are lifted, and further compresses the elastic member 7 (which may be a spring, but preferably has a wavy elastic structure and can be well accommodated in the lifting groove), wherein both sides of the rotating member 12 are limited by the fixing body 13 during lifting, so that the stable holding angle of the rotating member 12 and the lifting column 5 is lifted.

After the rotating member 12 is lifted to a slightly higher level than the fixed bodies 13, the lever body 690 is swung horizontally, and then the height of the rotating member 12 is lowered, so that finally, the two fixed bodies 13 are abutted against the lower side of the rotating member 12, and the rotating member 12 can be temporarily supported at the moment, wherein, the position and the angle of the rotating member 12 can be stably maintained because the elastic member 7 has larger downward elastic force and the bottommost end of the rotating member 12 is positioned between the two fixed bodies 13 at the moment, thereby being convenient for a worker to take down and install the new rolling cutter 4.

After the new rolling cutter 4 is installed, the rotating piece 12 is slightly lifted (manually by a worker), the transverse rod body 6 is rotated to enable the lifting column 5 to be vertical, then the transverse rod body 6 is lowered, the lifting column 5 passes through the limiting hole 3 until the transverse rod body 6 abuts against the top of the supporting column 2, and the limiting of the rolling cutter 4 is completed, so that the rolling cutter is simple and convenient. The rotating member 12 is elliptical, so that the angle of the rotating member 12 does not need to be completely rotated to be vertical when the lifting column 5 is lowered, but only needs to be close to the vertical state, and the fixed body 13 can guide and turn the rotating member 12 in the lowering process of the rotating member 12, so that the rotating member 12 is rotated to be vertical, and the operation convenience is higher.

It should be further noted that, in the present application (especially, in the value specification), all "setting" and similar descriptions express that there is or exists a connection relationship between two structures, but the specific means by which the two structures are connected is not limited too much, and is usually a conventional connection means, that is, it should be understood that the means is the prior art, and need not be repeated too much. For example, "a is provided with b", only the structure a has b, and both are specifically in the protection scope of the present application through welding, riveting, adhesive connection or integral molding, and "c is provided with d", only the d is connected with the c through rotation, and both are in the protection scope of the present application as long as the d is connected with the c through rotation of the bearing or the d directly passes through the c to be connected with the c through rotation.

The above description is only illustrative of the preferred embodiments of the present utility model and is not intended to limit the scope of the present utility model, and any alterations and modifications made by those skilled in the art based on the above disclosure shall fall within the scope of the appended claims.
