Description
Technical field
The utility model relates to the stable steering mechanisms of the paper-pressing mechanism of paper cutter, especially paper-weight.
Background technique
Paper cutter be it is a kind of paper is compressed after the equipment that cuts, what the quality of platen directly influenced paper cuts effect
Fruit.Platen uses paper-weight, and to guarantee accurately to cut, paper-weight needs to move up and down flexibly and front and rear, left and right balances.In paper
During cutting, in order to guarantee paper-weight uniform force realize balance push, cut it is previous as all paper can be placed on paper-weight
Centre after platen, cut.But when more demanding for cutter size, paper can be close to paper-weight right lateral side rule or left rear side
The gear paper of rule is placed, i.e., the side compression that paper is placed in paper-weight is cut, and causes the unilateral stress of paper-weight in this way, especially
Very narrow paper is cut, such as the namecard of 54mm, the unilateral stress of paper-weight is become apparent, and causes generation left and right during platen askew
Oblique problem seriously affects the raising of paper cutting precision.
Summary of the invention
The unilateral stress platen of paper-weight that the utility model will solve paper cutter in the prior art causes skew to influence cut paper
The problem of precision, the Double-gear for providing the utility model thus balance paper-pressing mechanism, which can protect in unilateral stress platen
It holds paper-weight balance to push, left and right skew will not be led to the problem of, cut paper precision is high.
To solve the above problems, the technical solution adopted in the utility model is to be respectively installed with a left side in the left and right portion of rack to lead
Bar and right guide rod are fixed with the paper-weight of power-actuated up and down motion on left and right guide rod, are characterized in that the rack
Straddle mounting has the gear shaft being able to rotate between left and right side, and the left and right end of the gear shaft is respectively fixed with left gear and right gear,
It is fixed with left rack gear on the left of the paper-weight and/or on left guide rod, is fixed with right rack gear on paper-weight right side and/or right guide rod,
The left rack gear and right rack gear are engaged with the left gear and right gear respectively.
The power drive is preferably oil cylinder driving, and the frame underside place placed in the middle is connected with platen oil cylinder, platen oil cylinder
Piston rod is downwardly against in the platen crossbeam of the left and right lower end of the guide rod institute bridging, the rack and pressure of two side direction of platen oil cylinder
Tension spring is respectively connected between paper crossbeam.
The power drive is also possible to motor driven, and gear shaft described in motor driven rotates or drive the paper-weight
It moves up and down.
Preferably be respectively equipped with left shaft holder and right bearing seat in the rack left and right side, the gear shaft by left bearing and
Right bearing is set in the left and right bearing block.
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
Detailed description of the invention
Fig. 1 is the utility model structure diagram；
Fig. 2 be in Fig. 1 mechanism under piston rod to the structural schematic diagram of stretching.
Label and counterpart in figure: 1 right rack gear, 2 right bearing seats, 3 right bearings, 4 right gears, 5 gear shafts, 6 tension springs, 7 pressures
Paper crossbeam, 8 platen oil cylinders, 9 left bearings, 10 left shaft holders, 11 left gears, 12 left rack gears, 13 left guide rods, 14 paper-weights, 15 machines
Frame, 16 right guide rods.
Specific embodiment
Double-gear balances paper-pressing mechanism, and the left and right portion of rack 15 is respectively installed with left guide rod 13 and right guide rod 16, left and right to lead
Paper-weight 14 is fixed on bar 13,16, the left and right side of rack 15 is respectively equipped with left shaft holder 10 and right bearing seat 2, left and right axis
It holds and sprocket drive spindle 5 is set with by left bearing 9 and right bearing 3 between seat 10,2, the left and right end of the gear shaft is respectively fixed with a left side
Gear 11 and right gear 4 are fixed with left rack gear 12,14 right side of paper-weight and right guide rod 16 on the left side of paper-weight 14 and left guide rod 13
On be fixed with right rack gear 1, left rack gear 12 and right rack gear 1 are engaged with left gear 11 and right gear 4 respectively, the downside of rack 15 place placed in the middle
It is connected with platen oil cylinder 8, left and right guide rod 13,16 lower end bridgings have platen crossbeam 7, and the piston rod of platen oil cylinder 8 is downwardly against in pressure
Paper crossbeam 7 is respectively connected with tension spring 6 between the rack and platen crossbeam of 8 liang of side directions of platen oil cylinder.
When platen oil cylinder 8 does not work, under the effect of two tension springs 6, platen crossbeam 7 is together with left and right guide rod 13,16 and paper-weight
14 in upper, and the piston rod of platen oil cylinder 8 extends downwardly when platen, and platen crossbeam 7 is together with left and right guide rod 13,16 and platen
Device 14 moves down, and compresses quires；If quires is located at the unilateral platen in paper-weight left or right side, due to left and right gear 11,4 with
Gear shaft 5 fixes corotation, and left and right rack gear 12,1 must be cooperateed with left and right gear 11,4 at this time, and synchronous and movement at the uniform velocity makes tooth
Wheel shaft 5 remains parallel with platen crossbeam 7, to guarantee that 14 left-right balance of paper-weight moves down compression quires, paper-weight 14 is not
It will appear left and right skew；The utility model also has simple structure, feature easy for installation.
