Abstract

The utility model relates to a paper-feeding device of a thermoprinting die cutter. The utility model has the technical proposal in that orderly stacked paper on a paper-feeding table are separated in sequence by a vacuum inhaling head, so the top printed paper can be continuously sucked to convey. A cam wheel link mechanism is driven by a driving shaft to make a sucking nozzle do mechanical motion, and an air distribution valve controls the air to do the following actions: 1) a fixed blowing nozzle blows wind towards the paper pile; 2) a paper-separating sucking nozzle sucks the top printed paper of the paper pile tightly; 3) a paper-delivering sucking nozzle sucks the printed paper tightly and delivers the printed paper backwards. Because the utility model adopts the structure that a rotary-type air distribution valve is used and is connected with a cam shaft into a whole, the delivery rate and the accuracy are increased.

Description

The high speed revolution paper transport

The utility model relates to device, particularly adapted the paper transport device thermoprint, cross cutting dual-purpose machine on of a kind of conveying single paper by printing equipment or machinery.

Paper transport is chewed, is blown to chew etc. and form by frame, axle drive shaft and suction, cam is installed on the axle drive shaft, and cam contacts with the connecting rod mechanism that with the frame is fulcrum, and suction is chewed and blown and chew the not end that is installed in connecting rod mechanism, according to the rotation of cam, order about inhale chew and blow chew do required up and down or move forward and backward.Suction has been chewed separation and has been inhaled to chew to inhale with transfer and chew, blow to have chewed fixedly to blow to chew to blow and chew with platen, fixedly blow to chew and blow to pile, blow loose paper, separation is inhaled to chew the single paper on the face inhaled from pile and is mentioned, platen blows the paper of chewing not picking up and fastens, and simultaneously the paper that picks up is held up, and transfer is inhaled to chew and sucked the sheet-fed that picks up and be fed forward.The one group of cam (driver train) that drives distributing valve work also is installed on the axle drive shaft of existing paper transport, being used for driving two reciprocating type distributing valves respectively carries out air-breathing and calm the anger, chew with blowing to chew with suction respectively by pipe and to link to each other, finish the work of above-mentioned conveyance of sheets.

The purpose of this utility model is the needs that paper transport improved speed and precision in order to satisfy, and designs a kind of distributing valve of high speed motion, and has connection and reasonable arrangement, compact conformation, characteristics attractive in appearance.

The purpose of this utility model is realized by the rotary distributing valve of axle drive shaft direct drive that by designing a cover promptly distributing valve is rotary, and the spool direct mount (connection) of distributing valve is on axle drive shaft.

Accompanying drawing 1 is a front view of the present utility model, and Fig. 2 is a top view, and Fig. 3 is the transmission device cutaway view, Fig. 4 is air-channel system figure, Fig. 6 inhales for separation and chews the transmission device scheme drawing, and Fig. 6 inhales for transfer and chews the transmission device scheme drawing, and Fig. 7 chews the transmission device scheme drawing for platen blows.1 is the paper transport frame among the figure, and 2 is distributing valve (distributing box), and 3 is fixedly to blow to chew interface, 4 inhale for separation and to chew, and 5 chew for the transfer suction, and 6 chew for platen blows, 7 is spool, 8 is valve body, and 9 is camshaft (axle drive shaft), and 10 chew motion cam for platen blows, 11 inhale for transfer and to chew the cam that seesaws, 12 inhale for separation and to chew the dipping and heaving cam, 13,14,15,16 be respectively fixedly blow chew, platen blow chew inhale with separation chew, air channel that the transfer suction is chewed, 17 is air pump.

Provide the utility model embodiment in conjunction with the accompanying drawings.

The utility model paper transport is by frame 1 as seen from the figure, axle drive shaft (camshaft) 9 and suction chew 4,5, blow and chew compositions such as 3,6, distributing valve (distributing box) is installed in the cavity on frame right side, two separations are inhaled and are chewed 4 respectively in the both sides of frame 1, its the place ahead is fixedly to blow to chew interface 3 and platen and blow and chew 6, and transfer is inhaled and chewed 5 rears that are positioned at frame.Drive 9 back at distributing valve, pass through bearing, be bearing on the frame 1, axle 9 right-hand members are equipped with platen and blow and chew motion cam 10, motion cam 11 is chewed in the transfer suction and motion cam 12 is chewed in the separation suction, cam contacts with the connecting rod mechanism that with the frame is fulcrum, suction chews 4,5 and blow and chew 3,6 ends that are installed in connecting rod mechanism, by chute the swing of connecting rod is done accordingly up and down or is moved forward and backward.Distributing valve 2 also is housed on the axle drive shaft, distributing valve is made up of spool 7 and valve body 8, spool is a cylinder, be directly installed on the camshaft, have four air channels on the periphery of spool, promptly fixedly blow and chew air channel 13, platen blow chew air channel 14 and separation inhale chew air channel 15, transfer is inhaled and is chewed air channel 16.Valve body 8 one is a cylinder, be sleeved on the spool, have two air chambers on it, on the corresponding spool two groups are blown and air-breathing air channel respectively, being inlet plenum blows and chews

air channel

13,14 and intermittently be connected with two groups, air-breathing air chamber is chewed air channel 15,16 with two groups of suctions and intermittently is connected, when air channel is connected with air chamber, gas circuit is connected, when stagger in air channel and air chamber position, gas circuit disconnects, so the length of air channel is selected according to work-hours, the angle position is determined according to mutual interactively (the cam link movement relation that comprises front end).Valve body 8 is a cylinder, be sleeved on the spool 7, and be directly installed on the frame 1, distributing box is made up of spool and valve body, the flow direction and flow to gas are controlled, on engineering, also claim distributing valve, also have special-purpose air flue on the frame 1, import and the pipe that comes by distributing box, outlet be connected the pipe that gas chews and be connected, just chew the gas of suction (blowing) through pipe by the control gas that distributes, joint, lead in the air flue of frame, and then be connected to gas and chew, so just make the layout of pipe in machine comparatively succinct, attractive in appearance.

The power of paper transport is passed to camshaft by the external world, and power cam and spool are made high speed revolution, and the relation between its camming movement and the intake and exhaust should meet the requirement of defeated paper, promptly

Fixedly blow gun is done upper and lower motion to printed sheet heap side air blowing (loose paper) → shaking of paper separation suction nozzle by cam, connecting rod mechanism chute.Suck and blow the uppermost printed sheet that unclamps, printed sheet and following printed sheet heap are separated (only allowing once to suck individual) simultaneously with the upwards lifting of printed sheet that sucks, the platen blow gun is done upper and lower movement in a curve by cam and four-bar linkage simultaneously, printed sheet heap fastened below first printed sheet that sucks, blow simultaneously, printed sheet held up lightly with pile further separate, the transfer suction nozzle is done forward movement by cam and connecting rod mechanism simultaneously, with the printed sheet that sucks deliver to treat on the splicing roller that glue laminated wheel fastens paper after, first cycle event of defeated paper finishes.Circulation goes down to finish defeated paper task like this.

Feature described and shown in the drawings is original in all specification sheetss.

The utility model is owing to adopted rotary distributing valve, and be installed on again on the same camshaft, therefore operating speed and precision have been improved greatly, and make compact conformation reasonable, no matter making the fluting board of above paper of 80 grams or thickness≤4 millimeter can both correctly carry, the time 13,000/hour of scooters.
