Abstract
The utility model provides a paper advance mechanism of a large width optical mark reading machine. The paper advance mechanism is mainly composed of a paper advance motor, paper advance wheel assemblies, a paper press wheel assembly, a base and a guide frame, wherein the base is provided with a backward inclined plane; the guide frame is vertically arranged on the inclined plane of the base so that the guide frame can form an included angle of 30-40 DEG with the vertical direction; the paper advance motor, the paper advance wheel assemblies and the paper press wheel assembly are all arranged on the inclined plane of the base; the utility model is provided with at least three paper advance wheel assemblies of which each axial line inclines an angle of 1.5-3 DEG towards the paper advance direction; along the paper advance direction, the speed of the paper advance wheel assemblies increase orderly; the paper advance motor is connected with each of the paper advance wheel assemblies through belts. The utility model enables the lower end of an information card to run constantly clinging to the inclined plane of the base in a tension state without producing wrinkle and warping phenomena, guarantees the stable and rapid running of the large width information card, and has the advantages of reasonable design and simple structure.
Description
(1) technical field
The utility model relates to and is used to read the optical mark reader that is coated with dot information on the release.
(2) background technology
Optical mark reader is to change the information on the release of being coated in into electric signal to pass to the high speed input equipment that computing machine is handled, being widely used in examination gos over examination papers, welfare lottery ticket, aspect such as sports lottery ticket and social investigation, mainly by paper advance mechanism, paper advance mechanism, base, guide frame, photoelectric sensor and control circuit are formed, paper advance mechanism, paper advance mechanism and guide frame are installed on the base, release is sent into paper advance mechanism by paper advance mechanism, paper advance mechanism makes release steady, apace by the slit between photoelectric sensor and the guide frame, the information on the release changes electric signal into by photoelectric sensor to be passed to computing machine and handles.At present, computerized information typing work is faced with problems such as diversification, complicated and data volume are big, and this just requires information carrier is that the breadth of release increases (more than the 8K).Release must be straight during by photoelectric sensor, its lower end will flush with the photoelectric sensor bottom all the time in operational process, otherwise will influence the Card Reader precision.The large format optical mark reader of existing domestic and international manufacturer production all adopts the straight-pushing paper moving structure, i.e. the release operation that is the level of state easily makes phenomenons such as release generation crape folding, warpage, influences the Card Reader precision, and complex structure, the cost height.
(3) summary of the invention
The utility model is at the deficiencies in the prior art, and a kind of simple in structure, large format optical mark reader paper advance mechanism that the Card Reader precision is high is provided.
The utility model adopts following solution:
This paper advance mechanism is mainly by chart drive motor, the paper feed wheels, the platen wheels, base and guide frame are formed, a dip plane is backward arranged on the base, guide frame is vertically mounted on this dip plane of base, make guide frame and vertical direction be 30--40 degree angle, chart drive motor, paper feed wheels and platen wheels are installed on the dip plane of base, the paper feed wheels have three at least, the axis of each paper feed wheels is all to page orientation inclination 1.5-3 degree, and the speed along page orientation paper feed wheels increases successively, chart drive motor is connected with each paper feed wheels by belt, and each paper feed wheels front all is equipped with the platen wheels.
The utility model makes release be the state of receding, under the downward-sloping paper feed wheels effect of relative page orientation, the release lower end is close to the operation of base dip plane all the time, and the paper feed wheels that speed increases successively make release be in tension all the time, can not produce crape folding, warping phenomenon, guarantee the steadily operation apace of large format release.Have characteristics reasonable in design, simple in structure, the Card Reader precision.
(4) description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is along the cut-open view of A-A line among Fig. 1.
Fig. 3 be among Fig. 1 B to view.
Wherein: 1, base, 2, the dip plane, 3, chart drive motor, 4, the paper feed wheels, 5, guide frame, 6, the platen wheels, 7, motor pulley, 8, the paper feed belt pulley, 9, torsion spring, 10, the paper feed wheel, 11, walk reel, 12, bearing seat, 13, belt
(5) embodiment
The utility model mainly is made up of chart drive motor 3, paper feed wheels 4, platen wheels 6, base 1 and guide frame 5 as seen from Figure 1.A dip plane 2 is backward arranged on the base 1, and the guide frame 5 that is vertically mounted on this dip plane is 35 angles of spending with vertical direction.Make the inclined operation of release like this, can only lean on the monolateral paper feed in release lower end, simplify the structure.Chart drive motor 3 is installed on the base dip plane 2 by support, and motor pulley 7 is housed on it.Paper feed wheels 4 and platen wheels 6 are installed on the dip plane 2 of base.The paper feed wheels have three, and each paper feed wheels front is equipped with platen wheels accordingly, and the platen wheels are pressed on the paper feed wheel 10 of paper feed wheels by the torsion spring in it 9, by friction gearing release are moved ahead.As shown in Figure 2, the paper feed wheels by paper feed wheel 10, walk reel 11 and bearing seat 12 is formed, bearing seat 12 is installed on the base dip plane 2 by screw, walk reel 11 by Bearing Installation in bearing seat 12, paper feed wheel 10 is equipped with in its upper end, and paper feed belt pulley 8 is equipped with in the lower end.The axis of each paper feed wheels is all to page orientation inclination 2 degree, make the release lower end be close to the operation of base dip plane all the time, because the bottom of photoelectric sensor is on base dip plane 2, this has just guaranteed that the release lower end flushes with the photoelectric sensor bottom all the time, has also just guaranteed the Card Reader precision in operational process.Paper feed diameter pulley along three paper feed wheels of page orientation reduces successively, because three paper feed belt pulleys all are connected (referring to Fig. 3) by belt 13 with motor pulley 7, therefore the speed along three paper feed wheels 10 of page orientation increases successively, this just makes release be in tension all the time, can not produce crape folding, warping phenomenon, guarantee the steadily operation apace of large format release.
Claims (1)
1, a kind of large format optical mark reader paper advance mechanism, by chart drive motor, the paper feed wheels, the platen wheels, base and guide frame are formed, it is characterized in that: a dip plane is backward arranged on the base, guide frame is vertically mounted on this dip plane of base, make guide frame and vertical direction be 30-40 degree angle, chart drive motor, paper feed wheels and platen wheels are installed on the dip plane of base, the paper feed wheels have three at least, the axis of each paper feed wheels is all to page orientation inclination 1.5-3 degree, and the speed along page orientation paper feed wheels increases successively, chart drive motor is connected with each paper feed wheels by belt, and each paper feed wheels front all is equipped with the platen wheels.
