With reference to fig. 2, a rotatable output shaft is arranged on the sliding base 21, three cutting knives 5 are installed on the output shaft, two adjacent cutting knives 5 are coaxial and can rotate relatively, a second motor 24 for driving the output shaft is arranged on the sliding base 21, a shade 22 is further arranged on the sliding base 21, namely, the second motor 24 drives the output shaft to rotate (for example, the output shaft is driven by the existing gear transmission mode), and then the cutting knives 5 are driven to cut, as shown in fig. 3, the three cutting knives 5 are installed on the output shaft through locking nuts 6 (the locking nuts 6 are consistent with those on the existing cutting machine, and the setting of reverse threads is adopted), and the outer diameter of the cutting knife 5 in the middle is not larger than the outer diameter of the cutting knives 5 on two sides.
As shown in fig. 2 and 5, a connecting body 23 nested on the output shaft is arranged between two adjacent cutting knives 5, the connecting body 23 includes a disc seat 231 and a rotating sleeve 232 rotatably arranged on the disc seat 231, the rotating sleeve 232 is coaxial with the disc seat 231, wherein the connecting body 23 is rotatably connected with the output shaft (i.e. the connecting body 23 is ensured to be capable of rotating on the output shaft);
a first elastic body 233 and a second elastic body 234 are arranged between the disc seat 231 and the rotating sleeve 232, the outer contours of the first elastic body 233 and the second elastic body 234 are involute curves, the base circle of the involute curves is the outer contour of the rotating sleeve 232, namely, the diameter of the base circle of the involute curve is the same as the outer diameter of the rotating sleeve 232, the cross sections of the first elastic body 233 and the second elastic body 234 are the same and are rectangular, the materials of the first elastic body 233 and the second elastic body 234 are the same, the first elastic body 233 is fixedly arranged on the disc seat 231, and one end, close to the rotating sleeve 232, of the second elastic body 232 is fixedly arranged on the rotating sleeve 232; referring to fig. 5, one end of the rotating sleeve 232 protrudes out of the disc seat 231, so that the middle cutting blade 5 is tightly abutted against the rotating sleeve 232 but not against the disc seat 231.
A plurality of cylindrical springs 235 are arranged between the first elastic body 233 and the second elastic body 234, two ends of each cylindrical spring 235 are respectively fixed on the first elastic body 233 and the second elastic body 234, the axes of the cylindrical springs 235 are tangent to the outer wall of the rotating sleeve 232, and the cylindrical springs 235 are different in length.
With further reference to fig. 4, the number of turns of the first elastic body 233 is greater than that of the second elastic body 234, the number of turns of the first elastic body 233 is equal to that of the second elastic body 234, the number of turns of the second elastic body 234 is 1/4, and a connection line between the starting points of the involutes of the first elastic body 233 and the second elastic body 234 passes through the center of the base circle thereof; the second elastic body 234 is surrounded by the first elastic body 233 by the involute structure of the elastic bodies and the arrangement of the turns, so that the positions of the first elastic body 233 and the second elastic body 234 on the disk seat 231 are deviated from the axis of the disk seat 231, an eccentric structure is formed (as shown in fig. 4, the first elastic body 233 and the second elastic body 234 are approximately positioned at the upper right corner in the figure), the potential energy is stored unevenly, and when the rotating sleeve 232 rotates relative to the disk seat 231, the stored potential energy is also concentrated at the upper right corner in fig. 3, so that the eccentric arrangement can form an impact type speed difference, for example, the eccentric wheel can generate impact when rotating.
When cutting timber, the cutting knife 5 that is located both sides is with timber cutting back, and then make the ligneous width greatly reduced of the cutting knife 5 of centre, and then the indirect ligneous intensity that has reduced this department, the cutting knife 5 of centre is also at the cutting that does not stop simultaneously, and the intensity that has in the ligneous different positions of cutting process is also different, therefore the cutting resistance that the cutting knife 5 of both sides and the cutting knife 5 of centre received is different, and then under the existence of connector 23, make cutting knife 5 can produce relative rotation and produce the speed difference, and utilize the inhomogeneous potential energy of storing in the connector 23 to impel the shredded wood bits between the adjacent cutting knife 5 to discharge.
In addition, the arrangement mode of the cylindrical spring 235 further promotes the uneven potential energy storage, according to the structural characteristics of the involute, the stress direction of any point (i.e. the normal of the point) on the involute is tangential to the base circle of the involute (as shown in fig. 4, for convenience of explanation, the normal of 10 elastic bodies is provided on the involute), so that the axis of the cylindrical spring 235 (i.e. the deformation direction of the cylindrical spring 235) is consistent with the stress direction, and further, when the elastic body just begins to deform, the cylindrical spring 235 can obtain a good stress direction; meanwhile, due to the characteristics of involute curves, the distance between the first elastic body 233 and the second elastic body 234 is different, so that the lengths of the corresponding cylindrical springs 235 are different, and when the springs rotate relatively, the compression or extension distances of the springs are different, so that multiple uneven stress can be formed on the elastic bodies, the unevenness of potential energy in the connecting body 23 is further increased, and when external cutting is performed, the uneven potential energy can form an impact effect, and accordingly, the discharge of sawdust is promoted.
In the actual manufacturing process, the elastic force of the elastic body and the cylindrical spring 235 can be set by itself, and the angle of relative rotation of the middle cutting knife 5 can be set to not more than 10 degrees when cutting wood.
In addition, due to the characteristics of the involute and the outer diameter of the cylindrical spring 235, when the cylindrical spring 235 is actually arranged, attention needs to be paid to the fact that interference cannot be generated among the springs, as shown in fig. 4, the base circle of the involute is divided into 12 equal parts, and 8 normal lines are drawn according to the equal parts on the base circle, due to the size of the cylindrical spring 235, the number of the cylindrical springs 235 cannot be dense at a position close to the base circle so as to avoid collision, so that the distribution of the cylindrical springs 235 is also uneven, and due to the fact that the cylindrical spring 235 is uneven in order to generate uneven potential energy, the uneven distribution of the cylindrical springs 235 does not affect the position, and when the cylindrical spring 235 is actually used, the number and the position of the cylindrical springs 235 can be arranged according to actual conditions.
During the use, as shown in fig. 4, for the initial position of connector 23 (when not producing relative rotation), cylindrical spring 235 is in the natural state this moment, when cutting, because the resistance that cutting knife 5 received is different, therefore under the existence of connector 23, middle cutting knife 5 can produce relative rotation for the cutting knife 5 of both sides, and then form the difference in speed, and then make first elastomer 233, second elastomer 234 and cylindrical spring 235 produce the potential energy, and utilize its structural feature to form unevenly distributed potential energy, and then when cutting, middle cutting knife 5 can produce the effect of "pause" when rotating, and then form the impact effect, discharge of the shredded wood bits that is located between cutting knife 5 with higher speed.
It will be apparent to those skilled in the art that various changes and modifications may be made in the present invention without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
