Abstract
The utility model provides a light roller knife of a web splitting machine, which comprises a rotary shaft, wherein a column of annular steel plates is fixedly welded on the rotary shaft, the annular steel plates and the rotary shaft are coaxial, every two adjacent annular steel plates in the column of annular steel plates are arranged at a certain axial interval, the annular steel plate in the middle of the column of annular steel plates is provided with a V-shaped notch, equilateral angle steel is welded and fixed in the V-shaped notch, the two ends of the equilateral angle steel are welded and fixed on the annular steel plates at the two ends of the column of annular steel plates, two columns of bolt via holes are formed in one side of the equilateral angle steel, and a cutting knife and the side of the equilateral angle steel are fixed by the bolts.
Description
Technical field
The utility model relates to roll paper dividing and cutting machine, is specifically related to the cylinder knife of roll paper dividing and cutting machine cut paper section.
Background technology
In papermaking, the trade of paper industry, the function of the roll paper dividing and cutting machine of printing industry widespread use is a paper that the paper cutting of paper roll is become suitable dimension, and it requires speed of cut fast, and cut paper is concordant, realizes that the key component of above-mentioned functions is cut paper section.Cut paper section comprises up and down two cylinder knifes, and as shown in Figure 1, cylinder knife comprises solid cylinder 2, has the V-arrangement groove on the cylinder, and cutting knife 3 fixedly fixes on the inwall of V-arrangement groove by two row's screws, and cylinder is supported on the bearing seat by rotating shaft 1.
The quality of the cylinder knife of this structure is larger, and rotator inertia is larger, causes the on off control complex structure, kinetic balance adjusting operation difficulty, and the vibrations during High Rotation Speed are larger.In addition, for mounting screw, need to be on V-arrangement groove wall drilling blind hole, the processing time consuming effort.
Summary of the invention
The technical problems to be solved in the utility model provides the light roll paper dividing and cutting machine cylinder knife of a kind of quality.
In order to solve the problems of the technologies described above, the technical solution of the utility model is:
A kind of cylinder knife of roll paper dividing and cutting machine, comprise rotating shaft, be welded with a row annular arrangement steel plate in this rotating shaft, this row annular arrangement steel plate and rotating shaft coaxial line, the certain axial spacing of being separated by of any two adjacent annular arrangement steel plates in these row, annular arrangement steel plate in the middle of being positioned in this row annular arrangement steel plate has V-notch, one equal angle is weldingly fixed in the V-notch and two ends are weldingly fixed on respectively on the annular arrangement steel plate that is in two ends, one side of equal angle is provided with two row bolt through-holes, and bolt is fixed this limit of cutting knife and equal angle.
The cylinder knife of above-mentioned roll paper dividing and cutting machine also arranges the shaft orientation reinforcing rib plate that connects them between described annular arrangement steel plate, bottom and the rotating shaft of shaft orientation reinforcing rib plate are welded and fixed.
The cylinder knife of above-mentioned roll paper dividing and cutting machine, totally 5 of described annular arrangement steel plates.
The utility model has consisted of cutter fixing support by rotating shaft, annular arrangement steel plate and equal angle, and quality has obtained very large reduction, and correspondingly, the kinetic balance adjustment of cylinder knife is easy, and on off control is also simpler, the vibrations when also having reduced High Rotation Speed simultaneously.In addition, only need to offer bolt through-hole at equal angle, by bolt cutting knife is fixed, be convenient to processing, also be convenient to change simultaneously cutting knife.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail:
Fig. 1 is the structural representation of existing cylinder knife.
Fig. 2 is structural representation of the present utility model.
Fig. 3 is the structural representation of another angle of Fig. 2.
Among the figure: 1 rotating shaft, 2 cylinders, 3 cutting knifes, 4 strengthen gusset, 5 equal angles, 6 annular arrangement steel plates.
The specific embodiment
Shown in Fig. 2 and 3, a kind of cylinder knife of roll paper dividing and cutting machine, comprise rotating shaft 1, be welded with a row annular arrangement steel plate in this rotating shaft, this row annular arrangement steel plate and rotating shaft coaxial line, the certain axial spacing of being separated by of any two adjacent annular arrangement steel plates in these row, annular arrangement steel plate in the middle of being positioned in this row annular arrangement steel plate has V-notch, one equal angle 5 is weldingly fixed in the V-notch and two ends are weldingly fixed on respectively on the annular arrangement steel plate that is in two ends, one side of equal angle is provided with two row bolt through-holes, and bolt is fixed this limit of cutting knife 3 and equal angle.
In order to increase the integral rigidity of cylinder knife, the shaft orientation reinforcing rib plate 4 that connects them also is set between described annular arrangement steel plate, bottom and the rotating shaft of shaft orientation reinforcing rib plate are welded and fixed.
Particularly, described annular arrangement steel plate is totally 5.
