As a preferable scheme, the outer end of the adjusting screw is provided with a twisting disc, and the periphery of the twisting disc is provided with friction lines.
As a preferred embodiment, the locking screw is a butterfly bolt.
The beneficial effects of the invention are as follows:
the mechanism can accurately adjust the cutting point of the blade, firstly, the clamp spring groove is processed on the cutter bar shaft, and the installation position of the cutter rest is positioned through the clamp spring, so that convenience and rapidness are realized; because the adjusting screw is provided with the positioning shaft shoulder which is matched with the shaft end surface of the cutter bar and is used for positioning and fixing the cutter clamping block, the cutter blade is prevented from colliding with the gauge blade, and the limiting position is the use starting position of the cutter blade, so that an installer is not required to find the positioning position, and the installation operation is convenient.
Because the fixed clamping cutter block is movably sleeved on the cutter rod shaft, one end of the cutter rod shaft, which is provided with the fixed clamping cutter block, is provided with an axially arranged threaded hole, an adjusting screw rod is penetrated into the threaded hole, a vertical positioning ring groove is arranged on the screw rod of the adjusting screw rod, a matched positioning through hole is arranged on the fixed clamping cutter block, and the end part of the set screw rod penetrates through the positioning through hole on the fixed clamping cutter block and is embedded into the positioning ring groove on the adjusting screw rod; after the cutting point of the blade is worn, the fixed clamping blade block and the blade are driven to move on the blade shaft by rotating the adjusting screw, and the height of the blade is unchanged due to spiral transmission, so that the displacement is accurate and reliable. When the whole knife rest mechanism is used for replacing a knife blade cutting point, the knife rest mechanism can be realized by rotating the adjusting screw in production without stopping and disassembling the knife rest; the utilization rate of the blade is improved; and the production efficiency is improved to a certain extent compared with the process of wearing and replacing the blade, the technical requirements of operators are reduced, and the labor cost is reduced.
Because be equipped with two locating holes with the size of two mounting holes on the blade in order to fix a position the blade height on the fixation clamp sword piece, the blade height satisfies the center of blade cutting point and two roller axle line and the work center coincidence of two gauge piece, and the blade passes through two short pins to be fixed a position on the fixation clamp sword piece, and the blade installation is swift, need not to correct the position and fix a position reliably.
Because the locating hole and dodge the hole setting on the blade on the midline, the lower part of blade also is equipped with cutting edge, and the upper and lower cutting edge of blade all can the clamping be used, simple to operate is swift, has improved blade utilization ratio.
Because the locking screw is a butterfly bolt, the assembly and disassembly are convenient, and the occurrence of accidents of damaging the blade due to excessive installation is prevented.
