The third-stage untwining teeth are annular V-shaped teeth.
The pitch of the adjacent three-level defibering teeth (along the length direction of the wheel) is smaller than the pitch of the adjacent two-level defibering teeth (along the length direction of the wheel), so that the purposes of log width extension and flexibility enhancement are achieved.

By adopting gear transmission, the power output can be enhanced, and the disassembly, assembly and maintenance can be facilitated.
Specifically, as shown in fig. 4-5, the breaking device a includes a machine table 1, and a protective cover is disposed outside the machine table 1. Has the function of safety protection.
The log unidirectional conveying channel S0 is arranged on the machine table 1, one end of the log unidirectional conveying channel S0 is a feed inlet, the other end is a discharge outlet, and the log unidirectional conveying channel S0 is used for forcing the small-diameter logs to be conveyed from the feed inlet to the discharge outlet;
the feed inlet of the log unidirectional conveying channel S0 is provided with a V-shaped guide chute to facilitate the input of the small diameter logs into the log unidirectional conveying channel S0.
Specifically, the machine table 1 of this embodiment is provided with a plurality of lower active traction wheels 10, the plurality of lower active traction wheels 10 are located on the same horizontal plane and rotate synchronously, the machine table 1 is further provided with a plurality of upper passive traction wheels 11 located above the lower active traction wheels 10 one by one, and the log unidirectional transportation channel S0 is formed between the lower active traction wheels 10 and the upper passive traction wheels 11.
The number of the lower active traction wheels 10 can be set according to the length of the small diameter log, for example: 2-8.
Secondly, the lower driving traction wheel 10 is a V-shaped wheel, and the upper driven traction wheel 11 is a V-shaped wheel. That is, the small diameter log is in contact with two positions of the lower active traction wheel 10 and the upper passive traction wheel 11 to convey the small diameter log.
In addition, in order to ensure the conveying efficiency, the outer walls of the two ends of the lower driving traction wheel 10 are respectively provided with lower inclined outer convex teeth 101 converged at the middle part of the lower driving traction wheel 10; the outer walls of the two ends of the upper driven traction wheel 11 are respectively provided with an upper inclined convex tooth 110 which is converged towards the middle part of the upper driven traction wheel 11.

Preferably, the breaking knife 2 of the present embodiment is a vertical straight knife.
The principle of the breaking device is as follows:
one end of the small-diameter log is arranged in the V-shaped guide chute and enters the log one-way conveying channel S0 under the action of axial thrust, and because the log one-way conveying channel S0 only has one-way conveying performance, when the small-diameter log is continuously pushed and output from the discharge hole, the breaking knife 2 at the moment can axially break the continuously pushed small-diameter log due to the fixed design, so that the breaking purpose is achieved.
The untwining equipment can directly untwin the small-diameter logs which are not broken, and can also untwin the broken logs.

The fluffing thickness space of the first-stage processing unit a, the second-stage processing unit b and the third-stage processing unit c is gradually reduced.
The untwining process is performed simultaneously in the above steps S1, S2 and S3, and the product in the untwining state of the flat plate shown in fig. 7 is obtained.
In the above steps S1, S2 and S3, the fluffing thickness space is adaptively adjusted by the primary, secondary and tertiary oil pressure lifting protection systems to prevent material jamming.
