It is more uncontrollable using precision, stability after screw thread mill for a long time and mobile accuracy can not ensure；Transmission support point is in the arm of force
Between, the translation depth of parallelism can not ensure；Two be that the screen cloth doubling bar of mechanical screen-tensioning machine is generally the cylindrical seaming of double flute or multiple-grooved, circle
Easily being skidded after cylindricality seaming clamping screen cloth, it is unstable to cause to draw in the net tension force.
The content of the invention
In view of the deficienciess of the prior art, be to provide a kind of screen cloth translational length can for main purpose of the present utility model
Control and stably, the high and non-slip mechanical screen-tensioning machine of printing of the seaming pressing goodness of fit.
To achieve the above object, the utility model provides following technical scheme：Mechanical screen-tensioning machine is used in one kind printing, is wrapped
It is provided with the taut network folder for clamping screen cloth in including rack, the surrounding of the frame, it is upper that the taut network folder includes that rubber is made
Several sections are formed between on clamp and lower clamp, the upper clamp and lower clamp for trapezoidal occlusion structure, the machine
The translating device for translating screen cloth is provided with frame, the translating device includes the translation arm of force, be connected with the translation arm of force two
Gear and it is arranged on the screw mandrel that driving turntable is carried between two gears.
It is preferred that, the quantity of the occlusion structure is 4.
It is preferred that, it is provided with frosted layer on the face contacted on the occlusion structure with screen cloth.
It is preferred that, two neighboring occlusion structure is in a center of symmetry relative to the contact surface of upper clamp and lower clamp to be set.
The utility model has the following advantages that screen cloth of the present utility model presss from both sides upper clamp and lower clamp relative to prior art
It is non-slip that screen cloth after pressing can bear 50N power.Four trapezoidal occlusion structures make screen cloth increase 4 times with taut network folder contact area,
The uniform of tension force of throwing the net is ensure that, adhesive tape uses hardness 80A rubber, reduced after adhesive tape pressing because rubber deformation causes tension force
Change, and adhesive tape bottom and taut network folder interface make adhesive tape difficult for drop-off using two sections of angle tongues.Controllable translation essence
Degree, driving turntable is rotated by 360 °, and translation arm of force translation is 2 ± 0.5mm.Lever principle makes the translation of the translation arm of force more laborsaving.Transmission
Bearing is at the two ends of the translation arm of force, it is ensured that the depth of parallelism of translation is to cause the overall stress of translational force arm evenly.Translation motion
The accuracy error reduction changed and cause bearing wear is forwarded by three fold axis.

Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of printing is used and is provided with use in mechanical screen-tensioning machine, including frame 1, the surrounding of the frame 1
In the taut network folder 2 for clamping screen cloth, the taut network folder 2 includes the upper clamp 3 and lower clamp 4 that rubber is made, and the upper clamp 3 is with
Several sections are formed between on clamp 4 for trapezoidal occlusion structure 5, are provided with the frame for translating the flat of screen cloth
Moving device 6, the translating device 6 includes the translation arm of force 7, two gears 8 being connected with the translation arm of force 7 and is arranged on two gears 8
Between carry driving turntable 10 screw mandrel 9.
Mechanical screen-tensioning machine is used in a kind of printing of the present utility model, and it to taut network folder 2 and translating device 6 by changing
Enter, relative to prior art have the advantages that to draw in the net translational length it is controllable and stably, the seaming pressing goodness of fit it is high and non-slip.
Specifically, being formed between on upper clamp 3 and lower clamp 4 that taut network folder 2 is made including rubber, upper clamp 3 and lower clamp 4 some
Individual section is trapezoidal occlusion structure 5, and the screen cloth doubling bar of prior art is generally double flute or the cylindrical seaming of multiple-grooved, and cylinder is stung
Easily being skidded after mouthful clamping screen cloth, it is unstable to cause to draw in the net tension force, and after screen cloth of the present utility model folder upper clamp 3 and lower clamp 4 are pressed
Screen cloth can to bear 50N power non-slip.Four trapezoidal occlusion structures 5 make screen cloth increase 4 times with the taut contact area of network folder 2, it is ensured that
Tension force of throwing the net it is uniform, adhesive tape uses hardness 80A rubber, reduces after adhesive tape pressing because rubber deformation causes the change of tension force
Change, and adhesive tape bottom uses two sections of angle tongues with the taut interface of network folder 2, makes adhesive tape difficult for drop-off.
In addition, being provided with the translating device 6 for translating screen cloth in frame, translating device 6 includes the translation arm of force 7, with putting down
