Utility model content
The purpose of this utility model be in order to solve to use existing for existing duplicating original paper oil absorption detection method easily occurring local leak that pressure, detection efficiency be low, testing staff's working strength height and the skimble-scamble problem of examination criteria, a kind of duplicating original paper oil absorption detection paper pressing device is provided, local leakage pressure can be avoided the occurrence of and significantly improve detection efficiency, the working strength of reduction testing staff, guaranteeing the unification of examination criteria simultaneously.
To achieve these goals, this utility model is by the following technical solutions:
A kind of duplicating original paper oil absorption detection paper pressing device, including one there is rectangle loading end put paper disc and rolling device, the left and right sides putting paper disc is provided with the tooth bar being parallel to each other, described rolling device includes the pressure roller being laterally located between the tooth bar putting the paper disc left and right sides, the left and right of pressure roller is respectively arranged at two ends with support shaft, described support shaft is provided with and the anti-skidding gear of the tooth bar of corresponding side engagement, and anti-skidding gear reference diameter is equal with the external diameter of pressure roller.
When needing the oil absorption detecting duplicating original paper, we by being adsorbed with oleic acid and can be coated with the sample of oil suction body paper and divide on the rectangle loading end putting paper disc in both sides, then testing staff front and back can promote pressure roller, pressure roller relies on the weight of self that sample is formed similar road roller and back and forth rolls equally uniformly, thus can be effectively prevented from sample and local leakage pressure phenomenon occur.It is dependent on what the weight of pressure roller itself realized owing to sample is rolled by this utility model, and pressure roller testing staff when putting paper disc and rolling around only need to overcome its minimum rolling frictional resistance, therefore can significantly decrease the working strength of testing staff, and correspondingly improve detection efficiency.It addition, pressure roller is progressively to roll the opposite side to sample from the side of sample, the unification rolling the concordance that sample rolls everywhere, beneficially examination criteria therefore can be effectively ensured that.Particularly, anti-skidding gear in the support shaft at two ends, pressure roller left and right is meshed with the tooth bar of both sides, and anti-skidding gear reference diameter is equal with the external diameter of pressure roller, therefore, the rolling distance of anti-skidding gear and the rolling distance of pressure roller are completely the same, it can be ensured that testing staff does not haves pressure roller skidding when promoting pressure roller, and guarantee that the rotating speed at two ends, pressure roller left and right is consistent, it is to say, pressure roller does not haves inclination when scroll forward and backward, so that it is guaranteed that the concordance that specimen surface is rolled by pressure roller.

Detailed description of the invention
With detailed description of the invention, this utility model is further described below in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of duplicating original paper oil absorption detection paper pressing device, it is applicable to repeatedly roll the duplicating original paper being adsorbed with oil slick, so that absorption oil slick on duplicating original paper is adsorbed on the oil suction body paper being coated on the upper and lower both sides of duplicating original paper, thus by weighing the weight of the duplicating original paper being adsorbed with oleic acid, and the difference of initial weight with duplicating original paper can be calculated and obtain the oil absorption of duplicating original paper.Specifically, this utility model includes putting paper disc 1 and can be used for rolling the rolling device of sample of a rectangle that can place sample, has smooth rectangle loading end 11 in the centre position putting paper disc, the sample that need to detect for placement.The left and right sides putting paper disc is respectively provided with tooth bar 12, and the tooth bar putting paper disc both sides is parallel to each other.Rolling device includes the pressure roller 2 being laterally located between the tooth bar putting the paper disc left and right sides, the two ends, left and right of pressure roller are respectively provided with support shaft 3, being fixedly installed in support shaft and the anti-skidding gear 4 of the tooth bar of corresponding side engagement, anti-skidding gear reference diameter is equal with the external diameter of pressure roller.
When needing the oil absorption detecting duplicating original paper, we can first weigh the weight of duplicating original paper sample, the most just it is adsorbed with oleic acid and is coated with the sample of oil suction body paper in both sides and divides on the rectangle loading end putting paper disc, now testing staff front and back can promote pressure roller, pressure roller relies on the weight of self that sample is formed similar road roller and back and forth rolls equally uniformly, thus can be effectively prevented from sample and local leakage pressure phenomenon occur.When covering no longer oil trace occurs on the oil suction body paper of the upper and lower both sides of duplicating original paper, the weight of duplicating original paper can be weighed, in order to calculate its oil absorption.It is dependent on what the weight of pressure roller itself realized owing to sample is rolled by this utility model, that is, testing staff is without to sample manual pressure, pressure roller testing staff when putting paper disc and rolling around only need to overcome its minimum rolling frictional resistance, therefore can significantly decrease the working strength of testing staff, and correspondingly improve detection efficiency.Particularly, anti-skidding gear in the support shaft at two ends, pressure roller left and right is meshed with the tooth bar of both sides, and anti-skidding gear reference diameter is equal with the external diameter of pressure roller, therefore, the rolling distance of anti-skidding gear is completely the same with the rolling distance of pressure roller, anti-skid rack can ensure that the rolling speed of the left and right sides of pressure roller and rolling distance are completely the same, and can ensure that and between pressure roller and sample, do not have skidding, that is, pressure roller does not haves inclination when scroll forward and backward, so that it is guaranteed that the concordance that specimen surface is rolled by pressure roller.It should be noted that we can make to be formed between anti-slop serrations wheel and rack matched in clearance, to guarantee to have in the vertical direction between anti-slop serrations wheel and rack gap when pressure roller rolls sample, it is to avoid the problem that tooth bar carrying pressure roller weight occurs.
Certainly, we can drive the rolling of pressure roller with U-shaped handle 5, and two openings of U-shaped handle support shaft with two ends, pressure roller left and right respectively is rotationally connected.So, when our hands drags the cross bar in the middle of U-shaped handle, can band dynamic pressure roller scroll forward and backward easily.Or, as shown in Figure 2, we also can arrange a pedestal 6 putting below paper disc, there are on pedestal two and be positioned at the bracing frame 61 putting the left and right sides in the middle part of paper disc, the left and right sides putting paper disc arranges corresponding rotating shaft, being connected on two bracing frames in left and right by axis of rotation so that putting paper disc, forming the structure of similar seesaw.Then it is positioned to put below on rear side of paper disc on pedestal and a bearing block 62 is set, bearing block is flatly arranged and is longitudinally arranged and rotating drive shaft 63, rotation bar 64 radially is set on the inner of drive shaft, one end of the end and a connecting rod 65 that rotate bar is hinged, the other end of connecting rod is then hinged with the lower surface putting paper disc, and the outer end of drive shaft then arranges a crank handle 66.When testing staff rotates drive shaft by crank handle, can swing up and down on rear side of paper disc by easily being promoted to put by the bar linkage structure rotating bar, connecting rod is constituted, now, whole paper disc of putting can swing around bracing frame.When the rear side putting paper disc declines, pressure roller can total side roll backward under the effect of own wt；When the rear side putting paper disc rises, pressure roller gets final product always forward side rolling under the effect of own wt, thus realizes pressure roller repeatedly rolling sample.
Uniformity sample rolled in order to ensure pressure roller, as shown in Figure 3, Figure 4, pressure roller of the present utility model includes rotary shaft 21 and the gland 22 being rotatably sleeved on outside rotary shaft, rotatably arranged with the support link 23 with the eccentric axis of rotary shaft in rotary shaft, the support shaft at pressure roller two ends is integrally attached to the two ends of support link, put paper disc both sides before and after rectangle loading end and be respectively provided with the depression 13 of rectangle, and the width caved in is more than the length of pressure roller.When testing staff promotes pressure roller to roll, support link can rotate together in company with support shaft, and rotary shaft is owing to designing with support link bias, therefore rotary shaft cannot rotate, formed between rotary shaft and support link now and relatively rotate, meanwhile, gland is also formed while rolling compaction sample and between rotary shaft and relatively rotates.Further, the axis of support link is positioned at the front side of pressure roller direction of advance, and in Fig. 3, arrow represents that pressure roller axis of the direction of advance of pressure roller, gland and rotary shaft when rolling sample is then positioned at the rear side of pressure roller direction of advance.When pressure roller is from putting the complete sample of rolling compaction on front side of paper disc to when putting on rear side of paper disc and fall in the depression put on rear side of paper disc, the weight of whole pressure roller is born by the tooth bar of the left and right sides, gland and rotary shaft outside pressure roller can produce a torque by relative support connecting rod under the effect of self gravitation, thus rotate down 90 degree, now the axis of gland and rotary shaft is then positioned at the lower section of support link axis.When we promote pressure roller the most forward, pressure roller first conflict rectangle loading end, gland and rotary shaft relative support connecting rod produce the rotation of 90 again, that is, gland and the rotary shaft of pressure roller are once coming and going the rotation of meeting relative support connecting rod formation 180 degree in rolling, and now the weight of pressure roller is applied to put on the rectangle loading end of paper disc again.So, sample same position is rolled position when reciprocating rolling and can change by pressure roller, that is, roll for twice before and after sample same position, the corresponding position on pressure roller has a differential seat angle of 180, thus can effectively support and avoid because the form error of pressure roller causes roll sample uneven.
Further, as it is shown in figure 5, we also can arrange the elastic pad 14 of double-layer seal on the rectangle loading end put paper disc, it is filled with compressed air in elastic pad, between the sidewall of two-layer up and down of elastic pad, connects rectangular array equally distributed connection post 141.The air pressure that inside is filled with compressed-air actuated elastic pad interior point is equal, therefore, when pressure roller rolls the sample in elastic pad, pressure roller can be made to form uniform pressure with elastic pad contact position, and contact for flexible face between pressure roller with elastic pad, thus effectively extend when pressure roller rolls sample and same position is rolled the time, be conducive to the oil slick adsorbed by sample quickly extrude and adsorbed by oil suction body paper, thus the efficiency of detection can be improved.Equally distributed connection post can avoid elastic pad to occur the phenomenon of intermediate muster after inflation, it is ensured that its surface smooth.
A kind of replacement scheme as elastic pad, as shown in Figure 6, we can make gland be made up of rubber, thus there is certain elasticity, and gland surface configuration 5 at the equally distributed helicla flute of circumferencial direction 221, thus form spiral helicine elastic raised line 222 between adjacent two helicla flutes, and the width of elastic raised line is identical with spiral fluted width on gland circumferencial direction.Pressure roller is when scroll forward and backward, and the elastic raised line on gland surface can make the face being similarly formed flexibility between pressure roller with rectangle loading end contact, thus extend when pressure roller rolls sample and same position is rolled the time.Particularly, contact area when helicla flute can make pressure roller roll sample reduces half, thus can correspondingly alleviate the weight of pressure roller on the premise of guaranteeing certain pressure, it is simple to testing staff's reciprocating pressure roller.Owing to 5 elastic raised lines on gland surface are uniformly distributed at circumferencial direction, say, that central angle corresponding between adjacent two elastic raised lines is 72 degree, and central angle corresponding between helicla flute and adjacent elastic raised line is 36 degree.Owing to pressure roller can rotate 180 degree during once back and forth, be equivalent to the central angle corresponding to two semi-elastic raised lines, so, the position of elastic raised line corresponding when pressure roller rolling compaction forward on sample just becomes spiral fluted position when pressure roller rolling compaction backward, and spiral fluted position corresponding when pressure roller rolling compaction forward on sample just becomes the position of elastic raised line when pressure roller rolling compaction backward.Owing to the width of raised line elastic on gland circumferencial direction is identical with spiral fluted width, therefore, in pressure roller once reciprocal roller compaction process, the whole surface of sample is the most effectively rolled, it is to avoid leakage pressure phenomenon occur.It should be noted that, we can be embedded a stainless steel sleeve on the medial wall of gland, arranges corresponding oil storage tank simultaneously, thus can reduce the frictional resistance between gland and rotary shaft on the periphery of rotary shaft, it is easy to the rotation of gland, it is to avoid skidding occurs between gland and sample.
