Abstract
The utility model discloses the paper cutting machine paper weight parts with anti-falling function, comprise paper-weight, paper-weight is done up and down setting above paper feeding platform, the upper end of left and right pull bar is connected with paper-weight, lower end is connected with left and right fork, the lower end of left and right fork connects by cross bar, paper-weight parts are also provided with spring assembly and draw on paper-weight is carried out, spring assembly one end is connected on spring base, the other end is connected on adjusting screw(rod), it is characterized in that: spring base is turning setting on cross bar, the side of spring base is provided with torsion spring, the direction of torsion spring promotion spring base upset and spring assembly pull the opposite direction of spring base, the below of spring base is provided with block, the designing requirement of block is to be turned to while contacting with block when spring base, the height of paper-weight is also in the top position of paper feeding platform.The utility model can prevent that paper-weight from dropping and falling on paper feeding platform in non-normal working situations such as spring assembly fracture, adjusting screw(rod) fractures, prevents that people's arm from being weighed wounded, guarantees personal safety.
Description
Technical field
The utility model relates to a kind of paper cutter, is specifically related to a kind of paper cutting machine paper weight parts with anti-falling function.
Background technology
Paper cutter needs paper-weight that the paper on paper feeding platform is compressed in the time carrying out cutting work, the paper cutting machine paper weight parts of prior art, conventionally structure is: comprise paper-weight, paper-weight is done up and down setting and is promoted by left and right pull bar above paper feeding platform, the upper end of left and right pull bar is connected with paper-weight, lower end is connected with left and right fork, the lower end of left and right fork connects by cross bar, left swing bar or right fork are by Hydraulic Cylinder, in the time that hydraulic cylinder upwards moves promotion left swing bar or the swing of right fork, left and right fork is by driving left and right pull bar that paper-weight is carried out to drop-down platen, paper-weight parts are also provided with spring assembly and draw on paper-weight is carried out, spring assembly one end is connected on spring base, the other end is connected on adjusting screw(rod), spring base is installed on cross bar.Although said structure can be realized platen and the revert action of paper-weight more satisfactoryly, but exist more serious safety defect, be paper-weight rest on a high position be by spring assembly pull realize, at this moment if there is non-normal working situations such as spring assembly fracture or adjusting screw(rod) rupture, get loose, paper-weight will lose returning virial and directly falling on paper feeding platform upwards so, operating area in paper-weight bottom forms danger, has a strong impact on personal safety.
Summary of the invention
The deficiency existing for prior art; the purpose of this utility model aims to provide one can prevent that paper-weight from falling on paper feeding platform in non-normal working situation tenesmus, and protection paper feeding platform is not damaged and guarantees the paper cutting machine paper weight parts with anti-falling function of personal safety.
The utility model is implemented by the following technical programs:
With the paper cutting machine paper weight parts of anti-falling function, comprise paper-weight, paper-weight below is provided with left and right pull bar, the upper end of left and right pull bar is connected with paper-weight, lower end is connected with left and right fork, the lower end of left and right fork connects by cross bar, left swing bar or right fork are by Hydraulic Cylinder, in the time that hydraulic cylinder upwards moves promotion left swing bar or the swing of right fork, left and right fork drives left and right pull bar that paper-weight is pulled down, paper-weight parts are also provided with spring assembly paper-weight are upwards drawn, make to keep paper-weight to return to extreme higher position after hydraulic cylinder release, spring assembly one end is connected on spring base, the other end is connected on adjusting screw(rod), spring base is installed on cross bar, it is characterized in that: spring base is turning setting on cross bar, the side of spring base is provided with torsion spring, the direction of torsion spring promotion spring base upset and spring assembly pull the opposite direction of spring base, the below of spring base is provided with block, the designing requirement of block is to be turned to while contacting with block when spring base, paper-weight and paper feeding table top are kept certain height.
Adopt after technique scheme, at paper-weight during in a high position, if there is spring assembly fracture or adjusting screw(rod) fracture, the non-normal working situation such as get loose, spring assembly pulls returning virial and will disappearing of spring base so, so torsion spring will promote spring base and return to spring base the direction upset that virial is contrary, after spring base upset, will come in contact with the block of spring base below, so, spring base has just stoped the movement of cross bar, also just stoped moving down of paper-weight, thereby prevent that paper-weight from falling to paper feeding platform, eliminate the risk of crushing that paper-weight and paper feeding table top form, guarantee personal safety.
Brief description of the drawings
The utility model has the following drawings:
Fig. 1 is structural representation of the present utility model,
Fig. 2 is the I portion enlarged drawing of Fig. 1.
Detailed description of the invention
Accompanying drawing has represented the technical solution of the utility model and embodiment, further describes by reference to the accompanying drawings more each details of embodiment below.
As shown in the figure, paper cutting machine paper weight parts with anti-falling function of the present utility model, comprise paper-weight 1, paper-weight 1 below is provided with left and right pull bar 2, the upper end of left and right pull bar 2 is connected with paper-weight 1, lower end is connected with left and right fork 4, the lower end of left and right fork 4 connects by cross bar 5, right fork 4 is promoted by hydraulic cylinder 7, when upwards moving, hydraulic cylinder 7 promotes right fork 4 while swinging, left and right fork 4 can be by drive left and right pull bar 2 that paper-weight 1 is carried out to the drop-down platen action that realizes simultaneously, paper-weight parts are also provided with spring assembly 6 and draw on paper-weight 1 is carried out, its objective is after hydraulic cylinder release paper-weight is remained on to extreme higher position, spring assembly 6 one end are connected on spring base 9, the other end is connected on adjusting screw(rod) 3, spring base 9 is installed on cross bar 5, spring base 9 on cross bar 5 taking rotating shaft 10 as swinging fulcrum turning setting, the right edge of spring base 9 is provided with torsion spring 8, torsion spring 8 promotes the direction (counterclockwise) that spring base 9 overturns and pulls the direction (clockwise) of spring base 9 contrary with spring assembly 6, the below of spring base 9 is provided with block 11, block 11 is fixed in frame, the designing requirement of block 11 is to be turned to while contacting with block 11 when spring base 9, the height of paper-weight 1 is certain altitude (being generally more than or equal to people's fist size) position above paper feeding platform also, thereby guarantee that paper-weight 1 can not fall to paper feeding platform, preventing that paper-weight from falling weighs people's arm wounded, guarantee personal safety.
The fall arrest course of work of the present utility model is: at paper-weight 1 during in a high position, rupture or adjusting screw(rod) 3 ruptures if there is spring assembly 6, the non-normal working situation such as get loose, spring assembly 6 pulls returning virial and will disappearing of spring base 9 so, so torsion spring 8 will promote spring base 9 and do anticlockwise upset, after spring base 9 upsets, will come in contact with the block 11 of spring base below, so, spring base 9 has stopped movement, also the movement of cross bar 5 and moving down of paper-weight 1 have just been stoped, thereby prevent that paper-weight 1 from falling to paper feeding platform, eliminate the risk of crushing between paper-weight and paper feeding platform, guarantee personal safety.
