In the present embodiment, cutting part 34 is saw blade, certainly in the application of reality, is not limited to saw blade.And additive to be cut is wooden branch, be preferably white mulberry strips, certainly, those skilled in the art can select suitable additive to be cut according to the actual requirements.
Present invention also offers a kind of cutting method of cutting machine, it specifically comprises the following steps:
Step 100, is positioned over described additive to be cut on described pay-off 1.
In the use procedure of reality, wooden branch 300mm ~ 400mm(is tied or pricks) be placed on the conveyer belt 142 of feed hopper 11, do not need to limit wooden branch and to join end to end or tail tail is connected.And the diameter of additive to be cut is less than 25mm, the appearance and size of satisfactory additive can be obtained like this.
Step 101, described control device controls described pay-off 1 and carries described additive to be cut, and regulates the step pitch of described additive to be cut.
Step 102, described control device controls described material pressing device 2 pressure according to the step pitch of described additive to be cut carries out first time pre-pressing to described additive to be cut.
In the application process of reality, the output shaft beam warp of motor 331 is crossed secondary transmission to the power transmission shaft 3334 of cutting part 34 and is driven cutting part 34 to complete reciprocating cutting stroke on guide rail 311 by cutting cylinder 321.Wherein, the pressure of material pressing device 2 is 0.5MPa ~ 0.8MPa.Can ensure that material pressing device 2 gives additive to be cut certain pre-pressing like this, reduce the gap each other of additive to be cut, avoid additive to be cut to produce splashing under malcompression state, damaged.
Step 103, described control device controls the cutting stroke that described cutter sweep 3 completes described additive to be cut.
In this step, cut in described additive process to be cut at described cutter sweep 3, described control device controls described material pressing device 2 and uninterruptedly applies secondary compression to described additive to be cut.The initial disconnected high-speed cutting due to cutter started when high-speed cutting has produced to be cut off and " disturbance " phenomenon that cutter at high speeds rotates generation can make " space " between additive to be cut to change.Thus continuously under a constant to be compressed again, whole " space " change is with the process compressed again until entirety is cut complete only, and therefore obtain very complete cutting section, branch epidermis cuts off completely, profile is intact, and additive to be cut can not splash in cutting process.
Step 104, described cutter sweep 3 resets.
Step 105, repeats step 100 ~ 104.
In the present embodiment, adopt above-mentioned cutting method, can obtain the shearing length of required additive, meanwhile, and the cutting section of the additive obtained after cutting is neat, and exocuticle adhesion, profile is intact.
In sum, the present invention can obtain the shearing length of required additive, and the cutting section of the additive obtained after cutting is neat, exocuticle adhesion, profile is intact, do not need pretreatment additive to be cut being done to early stage simultaneously, saved a large amount of human and material resources, reduced processing cost.
Although the foregoing describe the specific embodiment of the present invention, it will be understood by those of skill in the art that this only illustrates, protection scope of the present invention is defined by the appended claims.Those skilled in the art, under the prerequisite not deviating from principle of the present invention and essence, can make various changes or modifications to these embodiments, but these change and amendment all falls into protection scope of the present invention.
