The specific embodiment
The utility model will be further described below in conjunction with embodiment:
Fig. 1 is an example structure scheme drawing of the present utility model.A kind of down draught paper feeding device, it is by frame 1, bench board 6, the paper detent mechanism, inflatable body is inhaled mechanism of paper and is formed.Described paper detent mechanism is by left side baffle plate 2, right side baffle plate 4, and backstop 3, retaining lateral 9 is formed.The and arranged on left and right sides baffle plate is preset in the track on the bench board, can move along the paper cross direction, such detent mechanism can adapt to the conveying of different size specification paper, adjusts on the back and arranged on left and right sides baffle plate that finishes and locks with lock bolt, and the and arranged on left and right sides baffle plate is fixed on the bench board.Backstop is installed in the bench board rear end, and backstop can fixedly mount, and also backstop can be preset in the track on the bench board, can move along the paper length direction, and the position of backstop is adjusted appropriate back and locked with lock bolt.The retaining lateral has two kinds of mounting meanss, the one, be directly installed on the frame, be positioned at bench board front end paper import place, Fig. 2 has provided the structure diagram of the utility model retaining lateral, and described retaining lateral is made up of the fixed body 91, spring 92, adjusting screw(rod) 94 and the mobile 93 that are fixed on the frame that contain negative thread.Unscrew or tighten adjusting screw(rod), be i.e. compression or decontrol the high and low position of spring adjustable body.Gap between mobile lower end and the work top is for only can hold the height that sheet-fed can pass through.Another effect of retaining lateral is only to float on the upright position through the floating paper of inflatable body air blowing, blocks moving of paper forward direction.Described retaining lateral fixed body can also be selected another kind of mounting means: the work of retaining lateral fixed body is inserted on the slide block 95, on its duct 97 of inserting of living lock bolt 96 is arranged, described slide block also have one with aforementioned duct perpendicular can lock bolt 99 be arranged on the chute along the chute 98 of housiung separator slippage.Unscrew lock bolt 96, fixed body is mobile scalable retaining lateral and the fore-and-aft distance that piles up paper in the duct, unscrews lock bolt 99 scalable retaining lateral in the position of piling up on the paper Width.
Fig. 3 leads to scheme drawing on the exterior pipeline for the utility model inflatable body control cock is installed in paper detent mechanism left and right side baffle plate cavity.Described inflatable body is positioned at the blowing nozzle 42 of left and right side baffle-panels to the paper bottom side by the cavity 41 that is built in the left and right side baffle plate, control cock 43, and the gassing pipe that the cavity in the external pipe 44, left and right side baffle plate links to each other with vacuum pump is formed.Fig. 4 be Fig. 3 A to view, the front elevation of blowing nozzle, the air-flow that is blown out by blowing nozzle blows towards the paper bottom side, the paper of being convenient to pile up floats from the bottom.The blowing nozzle control cock can be adjusted the size of air-blowing quantity, to adapt to the weight of different paper.Fig. 5 leads to scheme drawing on the in-to-in pipeline for the utility model inflatable body control cock is installed in paper detent mechanism left and right side baffle plate cavity.Compare with Fig. 3, this effect of two kinds is consistent.Increase along with air-blowing quantity, air accumulation is below treating that paper feeding opens, forming air cushion floats the paper that overall stack is stacked on the bench board, be installed in the sidepiece at the bottom and the nearly end of bench board because of blow gun, more than on paper floats, paper vertically scatters, and with the increase of height, the degree of scattering weakens gradually.With regard to general run of thins, treat that paper feeding opens the height that piles up and be preferably 60 ~ 80mm.
Fig. 6 inhales mechanism of paper feed rollers axle generalized section for the utility model.Described suction mechanism of paper is made up of feed rollers 7, roller core 71, bearing 72, driving band 8 and the belt wheel that is installed on the transmission shaft.Described roller core is a hollow body, be fixed on the frame, the hollow body port links to each other with vacuum-pump line, the roller core outer rim has a groove 73 vertically upward, several holes that is arranged in a row 75 are arranged in the groove, described feed rollers is enclosed within on the roller core by the bearing sky, the outer rim of feed rollers is a little more than table surface, the serial aperture that the feed rollers outer rim has plurality of rows to be uniformly distributed along the circumference, its each round projection on axis all drops in the scope of groove length, by groove hole on the feed rollers and roller core hollow body are coupled together, belt conveyor is installed on feed rollers two ends outer rim and the aforementioned belt wheel.When inhaling mechanism of paper work, the belt wheel that is installed in transmission shaft is given driving band with transmission of power, and driving band drives feed rollers and rotates; Meanwhile, because of the roller core hollow body port that is fixed on the frame links to each other with vacuum-pump line, vacuum pump constantly extracts the air in the roller core hollow body, a round position and roller core groove up on the feed rollers that rotates begin on time, just form zone of negative pressure near this row's the position, hole on the roller, when increasing along with two hole alignment amounts, the adsorption affinity that negative pressure produces also increases thereupon, blow inflatable body to such an extent that undermost a piece of paper 74 of floating is adsorbed on the feed rollers, motion along with driving band, being adsorbed on sheet-fed on the feed rollers is transmitted band and sends to, rotation with feed rollers, a round also departs from groove gradually on the roller outer rim of original alignment, and adsorption affinity diminishes, and this helps sending to of paper, meanwhile another round on a time original row's the outer rim begins to aim at roller core groove up again, along with the rotation of roller, the negative pressure around the new round position is also increasing, also is that adsorption affinity is also increasing.That goes round and begins again constantly send paper forward like this.After this paper had sent, feed rollers adsorbed undermost paper again, began to send to new a piece of paper.
Inflatable body dispel the paper that piles up loose from degree better, the paper of the bottom is separated, the movable part extreme lower position of retaining lateral is adjusted to such an extent that only can limit passing through of sheet-fed, and the strong absorption of feed rollers just can be guaranteed success ratio and the paper feeding reliability that sheet-fed is carried in addition.
Above-mentioned example does not constitute restriction of the present utility model, and all employings are equal to the technical scheme that form obtained of replacement or equivalent transformation, all drop within the protection domain of the present utility model.
