Abstract

The utility model provides a multi-color multi-suction-disk circulating platform type screen printing machine which comprises a paper placing unit (1), a plurality of groups of printing units (2), a plurality of groups of drying units (3), and a paper fetching unit (4). The utility model is characterized in that the utility model is provided with a plurality of work benches (19) of suction disks, an upper guide rail (24) of suction disks, a lower guide rail (31) of suction disks, a front elevating carrying frame (26) and a back elevating carrying frame (6); thereby, the reciprocating circulation movement of suction disks can be realized; a plurality of suction disks carrying printing stocks not only move and stop simultaneously but also print and dry simultaneously for multiple stations, multiple paper sheets and multiple colors. The fixation of printing stocks depends on vacuum adsorption. The suction disks are driven by chains (8) to carry out horizontal movement, and each stop position of the suction disks is ensured with accurate positioning and precise overprint by positioning pins (15). The printing area of the machine can be as large as 1.5 meters by 3.6 meters or larger, and the machine can be adapted to different degree of softness and different thickness of printing stocks as long as flat printing is carried out.

Description

The polychrome multi-sucker desk-top screen process press that circulates away

(1) technical field

Belong to silk screen printing machine, particularly a kind of can polychrome, continuously, multistation, many paper, printing simultaneously, oven dry simultaneously once goes out the large format screen process press of finished product.

(2) background technology

Monochromatic machine is generally adopted in large format serigraphy at present at home, and characteristics are every seal half tones that all will change again a time of the same colour, again to version, relay stock one time, and whole printing process is time-consuming, take a lot of work.Also have few unit to use polychrome the single sucking disc or double suction flaking seal machine, though this wire mark machine can once go out finished product, go a step further earlier than monochromatic machine, but can only print of the same colourly respectively by a piece of paper, promptly print speed printing speed is slow.Can accomplish large format plurality of sheets of paper, polychrome, continuously, printing simultaneously, promptly fast good again type is still blank at home.

(3) summary of the invention

After the utility model was to provide and can once puts stock well, polychrome, multistation, many paper printed simultaneously, dry simultaneously continuously, once go out the flat surface screen printing machine of finished product, and print speed printing speed is 4～5 times of monochromatic machine.Whole printing machine is made up of four major parts: put the paper unit, and printing element, drying unit is got the paper unit, is a few look printings, and several groups of printing elements and drying unit are just arranged.

Whole printing machine is equipped with a plurality of suckers and two-layer up and down guide rail, and two (put paper and get the paper unit) is equipped with shears, can realize shuttling movement to guarantee suction plate bench along guide rail.The horizontal movement of suction plate bench is rotated and is realized by motor reducer drive sprocket wheel, a chain.A plurality of suckers move simultaneously, stop simultaneously, driver plate is housed on the chain, cooperate with the trundle on the suction plate bench, realize the motion transmission, the vertical displacement movement of sucker drives shears by cylinder and realizes, the fixing vacuum suction of leaning on of stock, on every look printing station precision positioning mechanism is housed all, constant to guarantee that sucker stops fixed-site afterwards at every turn, thus the accuracy of assurance multicolor overprint.One group of " light is solid " drying unit is all arranged behind every look printing station, interior dress " UV " lamp, during the every process of sucker drying unit, " UV " of the same colour printing ink of new seal sees that light is just dried, so that the horse back seal is of the same colour down.

Printing dolly and rail sections in the printing element have been taked particular structure, promptly not only work as seal car guide rail but also work as seal car driving-chain guard shield with this part of the big arm of print head frame, play simultaneously the supporting printing head again, realized the function of one three usefulness, it is simpler that machine construction is formed, and cost obviously reduces.Putting on the paper unit, also be provided with both direction detent mechanism in length and breadth, placing accurately, in getting the paper unit, be provided with automatic paper-fetching mechanism to guarantee stock.In this machine printing process, except that manually putting the paper, all the other operations all can realize mechanization, and the entire machine operation only needs 2～3 people.

(5) specific embodiment

The manufacturing and the course of work below in conjunction with this machine of description of drawings.The part that processes is assembled into each unit by Fig. 3, Fig. 2, by Fig. 1 each unit is linked together then, form complete machine, need several looks of seal,, can arbitrarily expand or dwindle just with several groups of printing elements and drying unit.The course of work: stock is put into assigned address on the sucker 19 of paper unit 1, promptly near the locating piece on Fig. 2 25, press play button then, the asepwirator pump 18 that is contained under the suction plate bench starts, stock is held, the alignment pin 15 of each workbench is thrown off subsequently, and upper strata chain drive motor 5 starts, and chain 8 moves thereupon.Driver plate 20 on the chain is docking together with the trundle 21 on the suction plate bench, and sucker is stopped after guide rail 24 moves to printing element 2, and the sucker on other stations also stops after the mobile phase same distance simultaneously.The shears of putting this moment in the paper unit 26 is reduced to second layer guide rail 31 places by cylinder 27 drives, waits for the sucker that returns, and then each alignment pin 15 in the printing element stretches out again, and suction plate bench is firmly pinned, and realizes accurately location.Print head 17 in each printing element and frictioning 16 are driven by cylinder and fall simultaneously at this moment, printing vehicle motor 13 subsequently starts, the chain 33 that orders about among Fig. 3 moves, drive block 35 on the chain drives printing dolly 14 and moves, also move with the printing frictioning 16 that links of seal car thereupon and to begin printing, stop after walking to a segment distance, printing frictioning 16 lifts again, and printing of the same colour finishes.At this simultaneously, sucker and print head on other a few look stations also carry out same course of action, are that used half tone is different with ink colors, have realized that thus polychrome, multistation, plurality of sheets of paper print simultaneously, have improved print speed printing speed greatly.Every printed stock of the same colour all passes through drying unit 3 when moving with sucker, the solid printing ink of light is seen the strong ultraviolet light of " UV " lamp 11, just does at once, to guarantee continuous printing.When sucker walked to delivery unit 4, asepwirator pump 18 became air blowing by air-breathing, and collection 9 falls, and motion with paper tape to the collection dolly on next door, so far a complete printed matter produces.The shears 6 in the delivery unit was driven by cylinder 7 and began to tilt to fall this moment, stopped to certain position, and the second layer guide rail 31 on the frame just in time docks with guide rail on getting paper unit shears 6 simultaneously.Alignment pin withdrawal on the shears 6, suction plate bench utilizes the inclined-plane to slide into second layer guide rail 31 under automatically, then the drive motors 28 of lower floor's chain 30 starts, and the trundle 29 on the chain drives suction plate bench fast moving back, turns back to rapidly and puts paper unit 1.Put shears 26 in the paper unit and drive by cylinder 27 and be raised up to the just in time butt joint of stopping of ground floor guide rail place, so far, realized the reciprocation cycle motion of suction plate bench.After a new sheet of printing stock is put well, click play button, new one takes turns the printing action repeats beginning again, and whole printing process only needs the operator that stock is put well, clicks button and gets final product.
