Band, the active mip rolls are driven by power plant；
It is multiple with being rotatablely equipped on the paper platform of the active mip rolls and the driven mip rolls corresponding position
Idler wheel, multiple idler wheels are in the width direction of the paper platform in row arrangement；
It is rotatablely equipped with paper bowl on the paper platform of active mip rolls upstream.
As an improvement with described in the paper bowl, the active mip rolls and the driven mip rolls corresponding position
Multiple elongated slots are offered on paper platform, the elongated slot is opened up along the length direction of the paper platform.
As a further improvement, the width for offering the long groove location is more than the active mip rolls or described driven
The diameter of mip rolls.
As a further improvement, the active mip rolls include the first roll body, first roll body is equipped with multiple
First groove of annular array setting, the extending direction of first groove are consistent with the extending direction of the first roll body；
The driven mip rolls include the second roll body, and it is recessed that second roll body is equipped with multiple annular arrays are arranged second
Slot, the extending direction of second groove are consistent with the extending direction of the second roll body；Positioned at second groove both sides
It is equipped with multiple arcs convex block on second roll body.
It is improved as further, the paper platform between the active mip rolls and the driven mip rolls
It is equipped with lateral paper guide, the lateral paper guide is distributed in the both sides of the paper platform, and between two lateral paper guides and the paper platform
Paper channel was formed, the width for crossing paper channel is greater than or equal to the width of the paper bowl.
As further improvement, it is equipped on the paper platform at each lateral paper guide both ends at least one
Paper guide block was equipped with paper gap between the paper guide block and the paper platform.
It being improved as further, the paper platform for being located at the driven mip rolls downstream is equipped with multiple row through-hole,
It is equipped with sensing element with the rack of the through-hole corresponding position.
It is improved as further, the paper platform for being located at paper bowl periphery is equipped with shield.
By adopting the above-described technical solution, a kind of paper feeding mechanism provided by the utility model has the beneficial effect that：
Since the paper feeding mechanism includes the paper platform being set in rack, multiple row venthole is offered on paper platform, is located at
It is rotatablely equipped with active mip rolls and driven mip rolls on the paper platform of multiple row venthole both sides, active mip rolls and from dynamic pressure
It send and is equipped with transmission belt between roller, active mip rolls are driven by power plant；It is corresponding with active mip rolls and driven mip rolls
Multiple idler wheels are rotatablely equipped on the paper platform of position, multiple idler wheels are in the width direction of paper platform in row arrangement；Positioned at master
Be rotatablely equipped with paper bowl on the paper platform of dynamic mip rolls upstream, be based on above structure, the paper feeding mechanism in practical applications, power
Device drives active mip rolls and the rotation of driven mip rolls, completes the pressure to filter paper on paper bowl by the cooperation with idler wheel later
It send and (this work is toward one end conveying filter paper far from paper bowl：Coordinate work by active mip rolls or driven mip rolls and idler wheel
When making, the frictional force principle that is generated with filter paper is realized), and then complete paper feed work；In the work of above-mentioned force feed filter paper,
When filter paper is corresponded with all ventholes, active mip rolls and driven mip rolls stop operating, later by radiation environment week
The air enclosed is introduced on detection device and passes through venthole, at this point, the dirt in air just stays on filter paper, and then completes
Sampling work, later active mip rolls and driven mip rolls rotate again, it is defeated by the filter paper downstream transport with sample areas
After the completion of sending, venthole corresponds and carries out the work of sampling next time with region new on filter paper.
In conclusion using the paper feeding mechanism, realize the mechanization to filter paper and convey automatically, participates in, have without artificial
Effect avoids the problem of radiant matter damages body；Meanwhile the conveying effect to filter paper of the paper feeding mechanism is good, smooth
Property it is high, provide guarantee for smoothly sampling, moreover, the paper feeding mechanism is simple in structure, the continuity that works is strong, and work efficiency is high.
It is long due to offering multiple elongated slots on the paper platform of paper bowl, active mip rolls and driven mip rolls corresponding position
Slot is opened up along the length direction of paper platform, and the width for offering long groove location is more than the straight of active mip rolls or driven mip rolls
Diameter provides condition to can effectively reduce the contact friction force of filter paper and paper platform by elongated slot for smoothly conveying filter paper.
Since active mip rolls include the first roll body, the first roll body is equipped with the first groove of multiple annular arrays setting,
The extending direction of first groove is consistent with the extending direction of the first roll body, thus by the active mip rolls with the first groove,
It can not only play the role of loss of weight, and the sideslip problem for correcting filter paper can be played；Since driven mip rolls include the second roll body,
Second roll body is equipped with the second groove of multiple annular arrays setting, the extension side of the extending direction of the second groove and the second roll body
To consistent；It is equipped with multiple arcs convex block on the second roll body of the second groove both sides, to by with the second groove
Driven mip rolls ensure that filter paper conveys to reduce the overall weight of driven mip rolls by the multiple arcs on the second roll body
Linearity.
Since the paper platform between active mip rolls and driven mip rolls is equipped with lateral paper guide, lateral paper guide is distributed in support
The both sides of cardboard, and paper channel was formed between two lateral paper guides and paper platform, the width for crossing paper channel is greater than or equal to paper bowl
Width；It is equipped at least one paper guide block on the paper platform at each lateral paper guide both ends, is equipped between paper guide block and paper platform
Cross paper gap, to being oriented to filter paper by lateral paper guide and paper guide block, while can also play prevent filter paper upwarp with it is grand
The problem of rising.
It is set since the paper platform positioned at driven mip rolls downstream is equipped on multiple row through-hole, with the rack of through-hole corresponding position
There is a sensing element, and since the filter paper (one big) after sampling needs to cut into the filter paper of fritter, later by multiple fritter filter paper
It overlays in magazine, magazine is transferred to detection unit simultaneously together with multiple fritter filter paper in it by transfer device again later
It is inside detected, to which this structure be arranged on paper platform by through-hole, directly smoothly convenient for the filter paper part after sampling
It is delivered to transfer device nearby and with through-hole to be correspondingly arranged, directly filter paper is cut on paper platform later, is passed through later
Induction of the sensing element to filter paper is transferred the corresponding filter paper of the through-hole into magazine to control transfer device, simple in structure, nothing
Filter paper need to be moved before cutting, substantially increase the continuity between adjacent two-step.
Since the paper platform positioned at paper bowl periphery is equipped with shield, to be protected the paper bowl of rotation by shield,
Prevent safety accident.
