Abstract
The utility model discloses a force measuring device for a paper feeding wheel set or a paper collecting wheel set. The force measuring device comprises a U-shaped support (1) and an independent scale pan (3) with a lifting rope (2). Weights (4) are arranged in the scale pan (3), V-shaped grooves (5) are arranged on two sides of the front end of the support (1) respectively, pressing plates (6) opposite to the V-shaped grooves (5) are arranged on the upper end surfaces of two sides of the support (1) respectively, and butterfly screws (7) are arranged in the middles of the pressing plates (6). The force measuring device has the advantages of simple structure and convenience in manufacture, is simple and convenient in operation, and can rapidly and accurately measure the friction torque of the paper feeding wheel set or the paper collecting wheel set.
Description
Technical field
The utility model relates to a kind of device for measuring force, particularly a kind of paper supply wheels or collection wheels device for measuring force.
Background technology
At present; Paper advance mechanism in the air radioaerosol monitor (a kind of instrument that airborne radioactive nuclide is monitored) need provide a kind of filtration paper web erecting device, and we are called the paper supply wheels this device, filters paper web and is with the drum paper supply wheels of packing into; The paper supply wheels are provided with adjustable friction system; Make it around main axis rotation the time, have certain resistance, the effect of this resistance is to make operating steadily of filter paper, does not play fold.Paper advance mechanism is except that having the paper supply Wheels group arrangement; Collection wheels also are installed, and it is that the filter paper that paper feeding roller is emitted is being gathered the device that reclaims behind the air sample, so the collection wheels also have one to reclaim pulling force; So just two problems have been produced: first; If the frictional resistance of paper supply wheels is excessive, easily paper tape is broken or be out of shape, so just confirmed a moment scope to frictional resistance.The second, the filter paper that the paper supply wheels are confessed is walked around behind a plurality of whirligigs and the draw samples and is reclaimed by the collection wheels, and this is with regard to the pulling moment of the inevitable requirement collection wheels moment of friction greater than the paper supply wheels.But, up till now, also be not useful on the device of measuring paper supply wheels and collection wheels moment of friction size.
The utility model content
The purpose of the utility model just provides a kind of paper supply wheels or collection wheels device for measuring force of accurately measuring paper supply wheels and collection wheels moment of friction size.
The purpose of the utility model is to realize through such technical scheme; A kind of paper supply wheels or collection wheels device for measuring force; It comprises U type support and independently has the scale pan of lifting rope that in scale pan, be provided with counterweight, said both sides at the support front end are respectively arranged with the V-type groove; Relative V-type groove place is provided with pressing plate respectively in the upper surface of support both sides, is provided with thumbscrew at the middle part of pressing plate.
Wherein, said pressing plate is the L type, and the one of which end is fixed on the bracket end face, and the other end is positioned at V-type groove top.
Owing to adopted technique scheme, the utlity model has advantage simple in structure, easy to make, this device is simple, convenient, can measure the moment of friction size of paper supply wheels or collection wheels fast and accurately.
Description of drawings
The description of drawings of the utility model is following:
Fig. 1 is the structural representation of the utility model user mode;
Fig. 2 is the left view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done further detailed explanation; But the utility model is not limited to these embodiments; Any on the present embodiment essence spirit improvement or substitute, still belong to the utility model claim scope required for protection.
Embodiment 1: like Fig. 1, shown in 2; A kind of paper supply wheels or collection wheels device for measuring force; It comprises U type support 1 and independently has the scale pan 3 of lifting rope 2 that in scale pan 3, be provided with counterweight 4, said both sides at support 1 front end are respectively arranged with V-type groove 5; Relative V-type groove 5 places are provided with pressing plate 6 respectively in the upper surface of support 1 both sides, are provided with thumbscrew 7 at the middle part of pressing plate 6.
Wherein, said pressing plate 6 is the L type, and the one of which end is fixed on support 1 end face, and the other end is positioned at V-type groove 5 tops.
The utility model is to use like this: at first the two ends with paper supply wheels axle or collection wheels axle are placed on respectively in the V-type groove 5; Tighten thumbscrew 7 then; Through pressing plate 6 that paper supply wheels axle or the axial compression of collection wheels is tight, an end of lifting rope 2 is wrapped on paper supply wheels or the collection wheels gets final product again; Through in scale pan 3, increasing or reduce counterweight 4; Determine the weight W of counterweight 4 in the moment that paper supply wheels or collection wheels rotate, wherein, the radius of paper supply wheels or collection wheels is R; According to moment formula M=WR, just can calculate paper supply wheels or collection wheels and rotate required moment size.The colleague, the strength that can also calculate between two wheels is poor, so just can control the friction force size and not broken to guarantee paper tape to operate steadily or be out of shape.
Claims (2)
1. paper supply wheels or collection wheels device for measuring force; It is characterized in that: it comprises U type support (1) and independently has the scale pan (3) of lifting rope (2); In scale pan (3), be provided with counterweight (4); Said both sides at support (1) front end are respectively arranged with V-type groove (5), locate to be provided with respectively pressing plate (6) at the relative V-type groove in upper surface (5) of support (1) both sides, are provided with thumbscrew (7) at the middle part of pressing plate (6).
2. paper supply wheels as claimed in claim 1 or collection wheels device for measuring force is characterized in that: said pressing plate (6) is the L type, and the one of which end is fixed on support (1) end face, and the other end is positioned at V-type groove (5) top.
