Abstract

The utility model relates to a high speed table octavo folding machine which is the special roller type folding machine for a mimeograph, an offset printer, a letter press, a photocopier, etc., mainly comprising two contra-rotating folding rollers, a paper feeding roller, an interlayer grid, a front break gauge, a cross break gauge and a delivery unit. In addition, the utility model is provided with a tuning device with adjustable force between rollers and a pressure spring. Compared with the universal knife folding machine, the utility model has the advantages of simple structure, small size and low cost, with folding speed above 100 page/s and error within 1 mm. A single-phase condenser motor of 60W can drive the utility model, and any octavo with single sheet weight of 30-150g can be folded.

Description

High speed table octavo folding machine

Desk type high speed octavo one folding machine is the roll-type folding machine of a kind of mimeograph duplicating machine, letter press, offset press and duplicator special use.

For many years, in the forwarding of octavo printing machine paper, manual method is all adopted in a folding, through roll over, take out, multiple working procedure such as pressure, labour intensity is big, speed is slow, quality also is difficult for grasp.Today, along with the development of office automation machinery, the mimeograph duplicating machine of octavo, offset press and micro computer laser photocomposing system are universal day by day, and it is particularly outstanding that the automation issues of a folding operation seems.In large-sized print factory, the folding operation is generally finished by gully formula three folding machines.If the knife-fold with a folding partly is an example, it by the folding roller of motor, conveyer belt, a pair of horizontal positioned and reverse rotation, be positioned at being positioned at the adjustable cross break rule of two sides about paper and relative position and being positioned at the also adjustable front folding gauge in its position of paper direction of advance and forming of jack knife directly over the folding roller slit, location usefulness, it all is some sideboards that these foldings are advised.In addition, also need be equipped with the control system that cover air pump suction paper and jack knife move up and down.Paper is delivered to by conveyer belt before the front folding gauge and is halted along cross break rule, and at this moment, jack knife drops to extreme lower position paper is sent into slit between two folding rollers, finishes folding action through two folding roller reverse rotation roll extrusion.Its principle is identical when eighty percent discount or three foldings, but structure is more complicated.This folding machine is bulky, complex structure, involve great expense, and can not do octavo one folding of mimeograph duplicating machine, offset press, duplicator and letter press and use in printing house and all kinds of office.As being example with cutter formula three folding machines, its overall dimensions are 3000 * 2000 * 1500mm ³, power of motor is more than 2KW, and the power of air-breathing induction system air pump motor obviously is inappropriate more than 3KW.

In order to overcome above-mentioned shortcoming, fill up the blank of desk-top octavo one folding machine in the field of printing machinery, the utility model proposes desk type high speed octavo one folding machine that is used for printing house and office automation more, it is a kind of roll-type folding machine, as shown in Figure 1, it is mainly by the left side of horizontal positioned, right two

folding rollers

1 and 2, the original thickness that is positioned at its two rollers gap of feeding-in roll 3(on right folding roller top and paper is suitable), be positioned at feeding-in roll 3 right sides and become the gap of its crack of interlayer grid 4(at an inclination angle (about 40～50 degree) will be a bit larger tham the thickness of paper with the direction of transfer of paper), be fixed on the interlayer grid 4 but position with nut and can open the front folding gauge 5 that number is adjusted according to folding, be positioned on the workbench by a left side, cross break rule 6 that right two adjustable plate washers are formed and the delivery device that is positioned under the right folding roller constitute, this delivery device is by rotating two

collection rollers

7,8 and the rubber collection band 9 that is enclosed within above them form, above-mentioned five rollers all use general steel to make and put with ball bearing, axle by a cover reduction gearing and belt pulley and motor links to each other the interlayer grid of wherein mentioning again, front folding gauge and cross break rule are all made with aluminum process.When motor rotation, except right folding roller was done counterclockwise to rotate, all the other each rollers all moved in the direction of the clock.If at this moment carry out manually defeated paper at workbench 10, just then paper 11 is gone by sending in the interlayer that direction rolls into interlayer grid 4 by feeding-in roll 3 and right folding roller 2, it just moves upward along the interlayer that tilts, and does not just readvance after being lived by 5 grades of front folding gauges.At this moment, go in the slit of two folding rollers about right roller 2 just rolls into paper 11, thereby finished the folding operation through the reverse rotation roll extrusion of folding roller.Paper after folding by folding roller 2 bring into 12 and the slit of collection roller 7 in, the rotation by 2 makes paper slide into collecting drum 8 places along rubber collection band 9 and is collected.In order to increase frictional force, on the face of cylinder of 1,2 and 3 three roller, all be with the hobboing cutter line.

In order to reduce rigging error,

roller

1,3 and 7 is that 12 of the bearing holder (housing, cover)s of material are on a public bearing bracket stand 13 by one by bronze or nylon 66 respectively all; For

pair roller

1 and 2,

roller

2 and 3, the pressure between the

roller

2 and 7 is finely tuned or is adjusted, and is with negative thread in bearing holder (housing, cover) 11, load onto the tuner of forming by double-screw bolt 14, nut pressing plate 15 and tuning nut 16, on double-screw bolt 14, also be with holddown spring 17.Screw or unscrew nut 16 and just can align roll gap pressure, 17 on spring has played automatic pressuring action.

Rolled over page or leaf when paper, just can deliver to the collection grid of making " " shape and collect by delivery device.

Fig. 1 is exactly this desk type high speed roll-type folding machine, and wherein 18 is supports, and the 19th, base all can make of general steel, but also cast aluminium forms.This is a principle schematic, and motor and gear do not draw.

Fig. 2 is exactly the vertical view of interlayer grid.

Fig. 3 is exactly the vertical view of front folding gauge.

Fig. 4 is the bearing bracket stand cutaway view.

This machine is used as power with single-phase condenser motor, and power is 60W. Its outside dimension is 250 * 400 * 420mm³Folding speed is at per minute more than 100 pages, the any octavo of individual weight in 30～150 grams can both folding, and folding is smooth, does not need to press and carries on the back, quality is good, error is no more than 1mm, can roll over books and periodicals, front cover, bulletin, teaching material, data, file and form usefulness, is special-purpose octavo one folding machine such as mimeograph, offset press duplicator and letter press, just be placed on the desk and can operate, so also be a kind of desk-top folding machine.
