But roll adjustment hand papercutter
Technical field
But the utility model relates to a kind of roll adjustment hand papercutter, mainly is applicable to the quick precise sampling of sample in the paper physical property detection.
Background technology
The scale error of sample is bigger to the testing result influence in paper physical property detects, so the sampling size to sample all has strict requirement in each detection method standard.Common solution is to use some special-purpose spacing hand papercutters in paper industry, guarantees the dimensional requirement of being materialsed.But there is a kind of general roll adjustment hand papercutter the domestic market at present, can cut the sample of different size.Adopt two kinds of methods to carry out the sample spacing but this roll adjustment hand papercutter is general: a kind of is that a scale is installed on the hand papercutter table top; Confirm sampling size through retaining chi on the scale; This method relatively is fit to cut the sample of large-size, and to the less demanding sample of the sample depth of parallelism; A kind of is the spacing of confirming hand papercutter baffle plate and bed plate with the several criteria piece; Cut the sample that different length and width require; The specimen size precision that this method cut is higher, but because the quantity of calibrated bolck is limited, so also can only cut some Commonly Used Sizes.
Summary of the invention
The technical problem that the utility model will solve is: to the problem of above-mentioned existence provide a kind of simple in structure, easy to use, sampling fast accurately, unrestricted to sampling size, but and the high roll adjustment hand papercutter of the sampling depth of parallelism.
The technical scheme that the utility model adopted is: but the roll adjustment hand papercutter; Comprise platen, side plate and bed plate; It is characterized in that: said platen bottom surface fixed installation guide rail; Be embedded with in this guide rail and be parallel to the slide block that platen is arranged, also can in guide rail, be free to slide along vertical bed plate direction; Said slide block is near the bed plate one end fixed installation baffle plate parallel with bed plate, the installation ruler parallel on this baffle plate with slide block, and being equipped with on the said side plate matches with ruler illustrates the pointer of distance between baffle plate and bed plate.
The lockable mechanism that is used for the slide block locking is prevented its slip also is installed on the said hand papercutter.
Said lockable mechanism comprises the nut that is fixedly installed on the side plate, and the threaded rod that is connected with this nut thread, this threaded rod drive end fixed installation handle, and Partner is installed the shell fragment of deformation with the slide block locking can be taken place under the threaded rod effect.
Said shell fragment comprises the deformation section that is fixedly connected with the threaded rod Partner; Its two ends form canned paragraph and the lock segments that is parallel to each other respectively to two opposite direction bendings, 90 degree respectively; Wherein canned paragraph is fixedly installed on the platen, and the free end of lock segments is aimed at slide block.
The beneficial effect of the utility model is: the utility model is installed baffle plate through line slideway on the hand papercutter platen; Simultaneously the ruler that is used to illustrate accurate distance between baffle plate and bed plate is being installed on the baffle plate, the accurate location through between baffle plate and the bed plate can make things convenient for the pattern that accurately cuts virtually any size; Compare with existing adjustable hand papercutter on the market; Not only more convenient to operate, and improved operating efficiency greatly, the pattern that can adapt to more dimensional requirements simultaneously cuts; And to different sampling sizes, the equal accord with Q B/T 1671-1998 of its error " the special-purpose die-cut appearance of paper and Board utensil general technical specifications " standard-required.In addition,, make baffle plate in adjustment process, keep the good depth of parallelism with bed plate all the time, thereby improved the depth of parallelism of sampling, guaranteed the precision of sampling owing to the gap very little (both precision-fit) between line slideway middle guide and the slide block.

The specific embodiment
Like Fig. 1-shown in Figure 4, present embodiment comprise platen 6, with the vertically arranged side plate 13 of this platen, and be arranged in the wherein bed plate 7 on limit of platen 6; Wherein 10 fixed installations of platen 6 underrun rebounds have the guide rail 1 of chute; Be embedded with the slide block 2 of precision-fit with it in the chute of this guide rail; Installation rear slider 2 and platen 6 place plane parallel, and can in the chute of guide rail 1, be free to slide along vertical bed plate 7 directions; Said slide block 2 is near the parallel baffle plate 3 of bed plate 7 one ends fixed installations and bed plate 7; Because the gap between guide rail 1 and the slide block 2 is very little; The slip of slide block 2 is rectilinear motion basically; Can not squint, make baffle plate 3 in adjustment process, keep the good depth of parallelism with bed plate 7 all the time, thereby improved the depth of parallelism of sampling; The ruler 8 parallel with slide block 2 is installed on the said baffle plate 3, pointer 9 is installed on said side plate 13 simultaneously, when baffle plate 3 carries out telescopic adjustment, can match through ruler 8 and pointer 9 and indicate the accurate distance of 7 of baffle plate 3 and bed plaves, reach the sample sampling size.
For guaranteeing sampling precision, lockable mechanism also is installed on the present embodiment hand papercutter, when baffle plate 3 is adjusted to desired location, utilize this lockable mechanism that slide block 2 lockings are prevented that it from continuing to slide.Said lockable mechanism comprises the nut 12 that is fixedly installed on the side plate 13; And the threaded rod 5 that is connected with this nut thread; The whole outside handle 4 of hand papercutter that is positioned at of this threaded rod 5 drive ends fixed installation, Partner are installed and can under threaded rod 5 effects, the shell fragment 11 of deformation with slide block 2 lockings be taken place.As shown in Figure 5; Shell fragment described in this example 11 comprises the deformation section 11-1 that is fixedly connected with threaded rod 5 Partner; Its two ends form canned paragraph 11-2 and the lock segments 11-3 that is parallel to each other respectively to two opposite direction bendings, 90 degree respectively; Wherein canned paragraph 11-2 is fixedly installed on the hand papercutter platen 6 through rebound 10, and the free end of lock segments 11-3 is aimed at slide block 2.
The operation principle of present embodiment is following: adjust the distance between baffle plate 3 and the bed plate 7 as required; When baffle plate 3 is adjusted to desired location; Turning handle 4 makes threaded rod 5 moving linearly under the effect of nut 12; The deformation section 11-1 that promotes shell fragment 11 deforms, and makes the free end of shell fragment lock segments 11-3 press slide block 2, thereby the locking of realizing slide block 2 prevents that it from continuing to slide; After sampling is accomplished; Counter-rotation handle 4, the deformation section 11-1 that utilizes threaded rod 5 to drive shell fragment 11 returns to the original form, and makes the free end of shell fragment lock segments 11-3 and slide block open in 2 minutes; This moment, slide block 2 can be free to slide, with the distance between adjustment baffle plate 3 and the bed plate 7.
But adopt the roll adjustment hand papercutter of present embodiment design good through practical effect, uses quick and convenient, for different sampling sizes, the equal accord with Q B/T 1671-1998 of its error " special-purpose die-cut kind of utensil general technical specifications of paper and Board " standard-required.
