Description

A kind of utilization screw rod adjusts the device of stamp magnetic platform magnetic force
Technical field:
The present invention relates to circular screen printer technical field, stamp magnetic platform magnetic is adjusted using screw rod in particular to one kind The device of power.
Background technology:
The scraer printing system of circular screen printer is divided into blade and scraped and two kinds of forms of magnetic bar printing.It is by stainless that blade, which is scraped, The elasticity of steel blade in itself is to scrape lines than more visible to apply the characteristics of pressure, printing, but adapts to the kind and width of fabric Wide is limited in scope, and is unsuitable for thick and heavy and wide cut fabric.Magnetic bar printing is to put to set below a rod iron, fabric in cylinder Row's magnet is equipped with, rod iron completes stamp by attraction so as to apply pressure to mill base.The svelteness degree of magnetic bar printing Blade is slightly poorer than to scrape, but it almost adapts to the printing in textiles of all thickness and widths, therefore application is further extensive.
Magnet below magnetic rod type cylinder printing machine fabric is divided into two kinds of permanent magnetic iron and electromagnetism magnetic platform, for permanent magnetic iron Its suction to bar magnet can be adjusted by changing the distance between magnet and bar magnet.As shown in figure 1, circular screen printer stamp The magnetic force adjusting of magnetic platform, wherein, the magnet in the stamp magnetic platform 11 uses permanent magnetic iron.Magnetic force adjustment described in Fig. 1 The operation principle of device is as follows:Cylinder component 20 installed in the bottom of magnetic platform supporter 10 drives the central shaft being connected with its piston 21 stretch or shrink, and the top of central shaft 21 acts on the bottom of rocking arm 30 to drive rocking arm 30 to rotate a certain angle, and is pivotally connected On magnetic platform supporter 10 the top of rocking arm 30 is by the jack-up of magnetic platform 11 or declines a certain distance, with change magnetic platform 11 and bar magnet it Between distance.By above-mentioned magnetic force adjusting, circular screen printer in operation, can be according to the thickness of different printcloths The size of magnetic platform magnetic force is adjusted with material, so as to reach optimal printing quality.
The content of the invention:
Technical problem solved by the invention:In the prior art, the magnetic force adjusting of circular screen printer stamp magnetic platform, leads to The flexible size to adjust magnetic platform magnetic force for the central shaft being connected with cylinder component piston is crossed, the Adjustment precision of its magnetic platform magnetic force has Wait to improve.
In order to solve the above technical problems, the present invention provides following technical scheme:
A kind of utilization screw rod adjusts the device of stamp magnetic platform magnetic force, including the element cylinder installed in magnetic platform supporter bottom Part, the central shaft being connected with cylinder component piston, middle part are articulated in the rocking arm on magnetic platform supporter;The bottom of the rocking arm is with Heart axle is connected, and the top of rocking arm is connected with the magnetic platform on magnetic platform supporter;
The device of the utilization screw rod regulation stamp magnetic platform magnetic force also includes the gear being fixedly mounted on side rail outer wall Driven gear connects in case, the gear train in gear-box, the drive link being connected with driving gear in gear train and gear train The adjusting bolt connect;Support base is installed with the side rail inner wall, support base accepts magnetic platform supporter, the curb girder Bottom is installed with support base bottom plate, and support base bottom plate is located at the lower section of support base, and the bottom of the support base bottom plate is provided with The internal thread block extended downwardly;The driven gear centre opens up screwed hole, and one end of adjusting bolt is screwed onto driven gear Screwed hole in, the other end and the internal thread block of adjusting bolt are spirally connected;
The bottom of the rocking arm is connected by ears ring with central shaft;The ears ring includes the company positioned at ears ring top Binding structure and extend downwardly structure positioned at ears ring bottom;The attachment structure of the ears ring includes pair that left and right is set up in parallel Ear-pole connection structure and center Axile connection structure, the ears ring top are connected by the bottom of ears attachment structure and rocking arm, institute Ears ring top is stated to connect by the end of center Axile connection structure and central shaft;What the adjusting bolt was spirally connected with internal thread block The structure that extends downwardly to ears ring is pushed up in one end, and the adjusting bolt and central shaft are located at the both sides of rocking arm bottom.
By above-mentioned technical proposal, the operation principle of the device of utilization screw rod regulation stamp magnetic platform magnetic force of the present invention is such as Under:Certain adjusting force is acted on drive link, and driven gear is transferred to by gear train;Because one end of adjusting bolt is spirally connected In the screwed hole of driven gear, the other end is spirally connected with internal thread block, therefore, and the rotation of driven gear can be driven after adjusting bolt Move back or advance;The other end top of the adjusting bolt extends downwardly the side of structure to ears ring, due to adjusting bolt and center Axle position is in the both sides of rocking arm bottom, and therefore, in the case where cylinder component is not ventilated, the retrogressing or advance of adjusting bolt can drive Dynamic ears ring is retreated or advanced, and the retrogressing or advance of ears ring can make central shaft stretch or bounce back, central shaft driving rocking arm rotation Certain angle, is articulated in magnetic platform jack-up at the top of the rocking arm on magnetic platform supporter or declines a certain distance, to change magnetic platform The distance between with bar magnet, that is, adjust magnetic force size;Afterwards, cylinder component is ventilated, under the cooperation of central shaft and adjusting bolt, Rocking arm is positioned, i.e., the distance between magnetic platform and bar magnet are determined.
In above-mentioned technical proposal, the ears ring extends downwardly structure equivalent to rocking arm is extended downwards, according to lever Principle, in the case where magnetic platform gravity is certain, adjusting bolt end can be reduced to ears ring equivalent to the rocking arm extended downwards The active force of lower extended structure, and then reduce the adjusting force acted on drive link, in this way, staff only need to be on drive link Applying less adjusting force can be adjusted to magnetic platform magnetic force.Further, since ears ring extends downwardly the presence of structure, adjustment Screw rod, which need to retreat or advance larger displacement amount, can just make the down or up certain displacement of magnetic platform, in this way, magnetic platform magnetic force can be improved Adjustment precision.
It is extraneous to pass through gear train driving adjustment spiral shell to the less adjustment power of drive link application by above-mentioned technical proposal The retrogressing or advance of bar, and then central shaft is stretched or is bounced back, accurately and effectively to adjust the size of magnetic platform magnetic force.Due to adjusting One end of whole screw rod is spirally connected with driven gear, and the other end is spirally connected with internal thread block, and adjusting bolt and the connectionless relation of ears ring, Therefore, during the adjustment of magnetic platform magnetic force, adjusting bolt is not easily broken, bent.
