Description
Technical field
The utility model relates to the follow-up paper folder of a kind of print product, and more particularly, it relates to a kind of detachable camshaft.
Background technique
Paper folder is used to the machine of folded sheet, has eighty percent discount dish paper folder and four fold dish paper folder.Can be used for the folding of various different size and thickness paper in scope of design, can be folded into the style shown in legend.Adjust easy, paper feeding is smooth, automatic paging, stepless speed regulation, lightly efficiently.Commonly use and print field, paper, after press printing, obtains the printed leaves of large scale entirety, then carrying toward in paper folder, being folded into the paper of specific dimensions size, being convenient to the cutting of paper, effectively improves the efficiency of printing sheets.
At present, Chinese patent 201310489799.0 discloses one " paper folder ", comprise frame, paper foldling mechanism and drive unit, paper foldling mechanism comprises paper folding apparatus, lower paper folding apparatus and synchronous belt wheel device, upper paper folding apparatus comprise paper folding substrate, upper pressure paper cam and on push away paper cam; Lower paper folding apparatus comprise lower paper folding substrate, lower platen cam and under push away paper cam; Synchronous belt wheel device comprises synchronous pulley, lower synchronous pulley and Timing Belt, two cam coaxials in upper synchronous pulley and upper paper folding apparatus are affixed, two cam coaxials in lower synchronous pulley and lower paper folding apparatus are affixed, and upper synchronous pulley or lower synchronous pulley are connected with drive unit.Rotated along cam profile by roller, drive paper folding apparatus to fold paper.But the cam of this structure, extremely bothers when mounted, and cam in use, and after there are wearing and tearing, maintenance extremely bothers, and specific cam can only fold the paper of specific dimensions, troublesome poeration during replacing cam.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of detachable camshaft being convenient to repair and replacement.
For achieving the above object, the utility model provides following technological scheme: a kind of detachable camshaft, the roller comprising cam and use with cam engagement, described cam is circular and comprises at least two pieces of arc blocks, the section of the arc block end described at least two pieces is bonded to each other, the radial direction of blocking direction and described cam of described section is that angle is arranged, and described cam also comprises the installing ring for fixing arc block.
Preferably, described installing ring and described arc block are provided with mounting hole, and described arc block is fixedly connected with installing ring by bolt.
Preferably, the mounting hole on arc block described in every block is at least provided with two.
Preferably, described arc block is made up of 40Cr material.
Preferably, described arc block surface hardening process.
Compared with prior art, by the setting of piecemeal, what can realize cam more easily is installed on dismounting, and when wearing and tearing in use occur cam, the arc block of the lower wearing part of dismounting is replaced separately, can also greatly reduce costs, simultaneously the stage direction of section be that angle is arranged with cam radial direction, in the process that roller can be made to move on cam, and stablizing of maintenance cam structure, ensure that roller can rotate by the stable profile line along cam, guarantee that paper can accurately fold.
Accompanying drawing explanation
Fig. 1 is the structural representation of the detachable camshaft embodiment of the utility model;
Fig. 2 is cam explosive view.
Reference character: 1, cam; 2, roller; 3, installing ring; 4, mounting hole; 5, rotating shaft.
Embodiment
Referring to figs. 1 through Fig. 2, the detachable camshaft embodiment of the utility model is described further.
A kind of detachable camshaft, comprise cam 1 and with cam 1 with the use of roller 2, cam 1 is fixedly connected on the sidewall of paper folder, and roller 2 remains the contact between cam 1, by the motion of roller 2 on cam 1 outer surface, realize the paper folding function of paper folder.Meanwhile, cam 1 is circular, after on the sidewall being mounted to paper folder, the effect of location can also be played by countershaft 5, the rotating shaft 5 of paper folder can be rotated in cam 1, when ensure that roller 2 rotates on the profile line of cam 1, the action of paper folding can better be passed on paper folder.Further, cam 1 comprises at least two pieces of arc blocks, and preferably, arc block is provided with three pieces, and every central angle corresponding to block arc block is 120 °, meanwhile, the section of three pieces of arc block ends is bonded to each other, is being joined end to end by three pieces of arc blocks, when being spliced into cam 1, arc block end face can fit together completely, makes the surface of cam 1 circumference does not exist slight crack, ensures that roller 2 can smoothly along cam 1 apparent motion.The radial direction of blocking direction and cam 1 of section is that angle is arranged, as described in Figure 1, section block the inner ring of direction from cam 1 to outer shroud, the moving direction along roller 2 tilts.Roller 2 from end face through out-of-date, section can be made to drop to minimum on the impact that roller 2 moves, will cam 1 be made because of the gap between end face to vibrate, cause the size of paper folding to occur deviation.
Meanwhile, when carrying out folding to the paper of different size, can also change different cams 1, according to the difference of cam 1, paper folder can be made to fold the size of paper different, make the application orientation of paper folder larger, adjustment folded size is more convenient.
Further, cam 1 also comprises the installing ring 3 for fixing arc block, and installing ring 3 and arc block are provided with mounting hole 4, and arc block is fixedly connected with installing ring 3 by bolt.When being fixed arc block, first arc block is connected successively, after forming complete cam 1 shape, arrange corresponding with spliced arc block for installing ring 3 again, alignd with the mounting hole 4 on arc block in mounting hole 4 position on cam 1, again by after screw bolt passes installing ring 3 and arc block, be fixedly attached on the sidewall of paper folder, ensure that arc block connects stable.By the setting of installing ring 3, the inner ring of installing ring 3 can be coordinated with rotating shaft 5, arc block and installing ring 3 are being fixedly attached to after on paper folder sidewall, are also positioning by the inner ring countershaft 5 of installing ring 3 with arc block, the more stable control reaching folio size.And the mounting hole 4 on every block arc block is at least provided with two, preferably, the mounting hole 4 on arc block is provided with two, and lay respectively at the two ends of arc block, by the mounting hole 4 on arc block two ends, arc block is fixed, ensures that arc block can stable being fixed on paper folder sidewall.
Further, arc block is made up of 40Cr material, and the Tensile strength of 40Cr is high, yield strength strong, and has higher fatigue strength and good toughness, can meet the performance requirement of cam 1.The surface structure intensity of arc block, through Quenching Treatment, effectively can be improved in the surface of arc block.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
