3 to Figure 11 it is described in detail the specific structure of cutting machine below with reference to accompanying drawings.
Fig. 3 is the exploded perspective schematic diagram of the roller of the cutting machine in Fig. 1；Fig. 4 is cutting for the roller of the cutting machine in Fig. 1
Face schematic diagram.
As shown, cutting machine 1 includes two rollers 34 arranged side by side, each roller 34 includes roller 35 and drum shaft
33, wherein drum shaft 33 runs through the central through hole O of roller 35.Preferably, roller 35 is made of nonmetallic materials --- particularly
It is made of the composite material with certain degree of hardness, ceramic material etc. that hardness is less than metal commonly used in the art, such as nylon, glass
The materials such as fiber reinforced nylon, engineering plastics, ABS plastic.Also, each roller 35 further includes roller connector, the roller
Connector is for being connected to drum shaft 33 for roller 35 and being preferably so that between roller 35 and drum shaft 33 without relative motion.?
In this preferred embodiment, it is preferable that the roller connector is the end cap 36 that the end of roller 35 is arranged in, such as institute in figure
Show, end cap 36 preferably have it is discoid and including evenly-spaced four through-holes 361, correspondingly in the end of roller 35
There are four threaded holes 351 for place's setting, and end cap 36 can be firmly-fixed to by four screws 37 end of roller 35 as a result,
Portion, also, as shown, end cap 36 includes that centre bore 362 passes through for drum shaft 33, it is set on the inner sidewall of centre bore 362
It is equipped with end cap keyway K, includes shaft key groove P at the position corresponding with end cap keyway K of the lateral wall of drum shaft 33, and
One driving key (not shown) of setting in the space is limited by end cap keyway K and shaft key groove P, thus drum shaft 33 can be through
End cap 36 is driven to rotate together by the driving key, so that end cap 36 drives roller 35 to rotate.Preferably, which sets
Be set to be mutually matched in shape with end cap keyway K and shaft key groove P respectively and almost without gap so that in rotary course
In, particularly in starting rotation and when speed change, relative motion is not present between drum shaft 33 and roller 35.Preferably, in this hair
In bright, end cap 36 is set as not contacting with tube-like piece 19, such as shown in Fig. 3, can be provided in the end of roller 35 recessed
Enter portion 353 and end cap 36 is accommodated in concave portion 353, can similarly there are other a variety of set-up modes, such as can will hold
Lid 36 is sized to smaller size, without concave portion 353 is arranged.In addition, two ends in roller 35 are equal
It is provided with end cap 36, thus more stably driving roller 35.
In the above-described embodiment, using made of nonmetallic materials, roller 34 is come supporting tubular part 19, due to non-
Metal material hardness is relatively low and has relatively high flexibility, therefore tube-like piece surface can be effectively prevent to damage
Hurt, and is improved by the configuration to roller, indirectly transmitted the movement of drum shaft using the roller connector
To roller, the mill of pair roller barrel when effectively can avoid directly driving the roller of non-metallic material using the drum shaft of metal material
Damage, can effectively extend the service life of device, and this roller connector is easily changed and safeguards, therefore with higher
Cost-effectiveness.Improved roller can not only effectively avoid the abrasion to tube-like piece surface, and can provide tube-like piece
Stable support and rotation.Also, it is highly preferred that as shown in Figure 4, existing between the central through hole O and drum shaft 33 of roller 35
Gap so that there is no directly contacting between roller 35 and drum shaft 33, thus preferably avoid roller 35 and drum shaft 33 it
Between abrasion, and be conducive to save material.
In alternative embodiments, end cap for example can also be connected directly to drum shaft and welding, being connected together
To be rotated together or end cap can also be integrally formed with drum shaft with drum shaft；Also, end cap can be for example including one
Body formed insertion section, the insertion section can be one or more and be inserted into roller and end cap is fixed to roller.
In addition, end cap 36 is in centrosymmetric discoid about drum shaft 33 and wraps in above-mentioned preferred embodiment
Evenly-spaced four through-holes 361 are included, four screws 37 for thus implementing connection make 35 stress of roller more evenly.But this
Invention be not limited to above-mentioned configuration, in alternative embodiments, end cap can in for example rectangular, rectangle, ellipse, diamond shape or other
About the centrosymmetric shape of drum shaft 33 or end cap can also in about the non-centrosymmetrical shape of drum shaft, such as from
The form for the sheet material part that drum shaft 33 only extends to side or any profiled shape, as long as roller 35 can be connected to and will be rolled
The movement of cylinder axis 33 is transferred to roller 35, and for the end cap of these shapes, as previously described about end cap and roller
Power transmitting or connection type between axis are also applicable.
On the other hand, end cap may not be single integral piece, but including at least two end caps structure independent of each other
Part, at least two cover members similarly may be set to be about drum shaft central symmetry or non-central right about drum shaft
Claim.For example, the cover member of multiple sheet material part forms only extended from drum shaft to side can be set, the cover member is for example
It is connected by screw to roller, and the cover member can for example be soldered to drum shaft or may include as described above
End cap keyway is to be transferred to roller for the movement of drum shaft as described above, also, multiple cover members can arrange
For about drum shaft central symmetry or about drum shaft non-centrosymmetry.Based on the present invention, other similar configurations will be it is aobvious and
It is clear to.
In addition, the roller connects in addition to the roller connector that roller end is arranged in end cap version as described above
Fitting can also include at least one plug division being arranged between roller and drum shaft, which can be soldered to drum shaft
Or it is integrally formed with drum shaft, and the plug division is inserted into roller and roller is fixed to drum shaft.
It is the schematic cross-section of the auxiliary wheel of the cutting machine in Fig. 1 referring to Fig. 5, Fig. 5.
As previously mentioned, knife unit 70 can also include auxiliary wheel 75, auxiliary wheel 75 is located at the two sides of cutter 72 and warp
It is mounted on auxiliary wheel support 76 by respective pin 77, specifically, auxiliary wheel 75 includes: idler wheel 751, the outer peripheral surface and pipe of idler wheel
Shape part 19 contacts, and similarly, and in order to avoid the abrasion to tube-like piece surface, idler wheel 751 is also by as described above nonmetallic
Material is made；And roller bearing 752, roller bearing 752 is through simultaneously supporting rollern 751, so that idler wheel 751 can be with roller bearing 752 together
