Finally, the double-roller seat 23 slides reciprocally on the frame seat 1 under the power of the double-roller transverse moving driving motor 28, and friction generated during moving can be effectively reduced through the cooperation of the double-roller transverse moving sliding groove and the double-roller transverse moving sliding rail 25, so that the aim of transversely moving the two double-roller single bodies 26 is finally fulfilled.
In this embodiment, the two-roller rotation driving assembly includes two-roller rotation driving motors 24, and the two-roller rotation driving motors 24 are respectively located at two ends of the two-roller single body 26, and it should be noted that fig. 3-4 are schematic diagrams for illustrating specific working principles, and some parts will be briefly drawn, and fig. 4 only shows one two-roller rotation driving motor 24, but actually shows two parts, and the reference to fig. 2 is right.

In actual use, the dual-roller rotary driving motor 24 is started, and is in transmission connection with the dual-roller first driving sprocket through the dual-roller first driving sprocket, so that one (located above) dual-roller single body 26 is driven by the dual-roller rotary driving motor 24 to rotate. Then, under the transmission action of the double-roller second driving sprocket and the double-roller second driven sprocket, one (upper) double-roller single body 26 drives the other (lower) double-roller single body 26 to rotate.
In this embodiment, the specific structure of the table traversing driving assembly is the same as the structure and working principle of the dual roller traversing driving assembly. Specifically, the stage traversing drive assembly includes a stage traversing drive gear box 31, a stage traversing drive screw 32, a stage mount 33, a stage drive shaft 37, and a stage traversing drive motor 38. The frame seat 1 is provided with a tool table transverse sliding rail, the tool table seat 33 is provided with a tool table transverse sliding groove, and the tool table transverse sliding rail is in sliding connection with the tool table transverse sliding groove.

The two table traversing driving screw rods 32 are arranged perpendicular to the table driving shaft 37, which changes the driving direction of the table traversing driving motor 38 through the table traversing driving gear box 31. When the cutter table transverse moving driving motor 38 is started in use, the cutter table transverse moving driving motor 38 drives the cutter table transmission shaft 37 to rotate, the cutter table transmission shaft 37 drives the two cutter table transverse moving driving screw rods 32 to rotate through the two cutter table transverse moving driving gear boxes 31, and the cutter table transverse moving nut seat is fixed on the cutter table seat 33 and cannot rotate, so that the cutter table transverse moving nut seat drives the cutter table seat 33 to do reciprocating transverse moving motion along the direction of the cutter table transverse moving driving screw rods 32 under the driving of the rotation of the cutter table transverse moving driving screw rods 32. Therefore, the cutter seat 33 slides reciprocally on the frame seat 1 under the power of the cutter seat transverse moving driving motor 38, and friction generated during movement can be effectively reduced through the cooperation of the cutter seat transverse moving sliding groove and the cutter seat transverse moving sliding rail, and finally the purpose of transverse movement of the rotary cutter 34 is realized.

It should be noted that, the plate pressure gauge supporting seat 35 can adjust its relative position with the knife stand 33 according to the need, and then fix it by the screw. As can be seen from fig. 1, an output channel for the plate is formed between the plate pressing rule body 36 and the rotary cutter 34, and the distance between the plate pressing rule body 36 and the rotary cutter 34 can be adjusted by adjusting the position of the plate pressing rule supporting seat 35, so that the plates with different sizes are cut.
In this embodiment, for the specific structure of the single-roller traverse driving assembly, which is the same as the structure and operation principle of the double-roller traverse driving assembly and the knife table traverse driving assembly, specifically, the single-roller traverse driving assembly includes a single-roller traverse driving motor 41, a single-roller traverse driving gear box 42, a single-roller traverse driving screw 43 and a single-roller seat 45. The knife stand 33 is provided with a single-roller transverse sliding rail, the single-roller stand 45 is provided with a single-roller transverse sliding rail, and the single-roller transverse sliding rail is in sliding connection with the single-roller transverse sliding rail. The output shaft of the single-roller transverse movement driving motor 41 is in transmission connection with a single-roller transmission shaft, the single-roller transmission shaft is connected with the input ends of two single-roller transverse movement driving gear boxes 42, the output shafts of the two single-roller transverse movement driving gear boxes 42 are respectively in transmission connection with a single-roller transverse movement driving screw rod 43, two sides of a single-roller seat 45 are respectively fixed with a single-roller transverse movement nut seat, and the single-roller transverse movement driving screw rod 43 is in threaded connection with the single-roller transverse movement nut seat, so that a screw-nut pair structure is formed.

Therefore, the purpose of the single roller seat 45 sliding back and forth on the cutter base 33 under the power of the single roller traversing driving motor 41 is to make the single roller seat 45 move back and forth relative to the cutter base 33, as can be seen from fig. 1, the end of the rotary cutter 34 is located on the same horizontal line with the center of the wood core, the center line of the single roller body 46 and the center line of the wood core are not located on the same horizontal line, the two lines are in a straight line, the diameter of the wood core is continuously reduced, if the single roller body 46 moves transversely by the same distance with the rotary cutter 34, the wood core is not contacted, so that in order to make the single roller body 46 always clamp the wood core, the single roller body 46 needs to move synchronously with the rotary cutter 34, and then the single roller body is driven by the single roller traversing driving assembly to move transversely, so that the distance can be more than the distance of the rotary cutter 34, and the single roller seat can always abut against the outer side of the wood core. And through the cooperation of single roller sideslip spout and single roller sideslip rail, the friction that produces when can effectually reducing and remove.

For the working principle inside it, reference may be made to fig. 4, where only the single-roller traversing driving gear box 42 is taken as an example, two bevel gears (only a part of structures related to the working principle are shown in fig. 4, but not all structures inside the gear steering box) are included in the single-roller traversing driving gear box 42, the bevel gears penetrated by the single-roller transmission shaft are transmission shaft bevel gears, the bevel gears penetrated by the single-roller traversing driving screw 43 are screw bevel gears, and the transmission shaft bevel gears are meshed with the screw bevel gears, so as to realize the vertical transmission connection between the single-roller transmission shaft and the single-roller traversing driving screw 43. Of course, the inside of the existing gear steering box may be provided with two transmission shaft bevel gears, the single-roller transmission shaft sequentially penetrates through the two transmission shaft bevel gears, the two transmission shaft bevel gears are located on two sides of one screw rod bevel gear and are meshed with the screw rod bevel gears, or other types of gear steering boxes are adopted, and a person skilled in the art can completely select a proper model according to actual needs. The specific structure of the two-roller traverse drive gear box 21 and the table traverse drive gear box 31 is the same as that of the single-roller traverse drive gear box 42, and therefore, description thereof will be omitted.
