Description

Fiber composite bag of cement shearing device

The utility model relates to a kind of bag of cement cutting machine, fiber composite bag of cement conveying specifically, shearing device.

Must cut off after the bag of cement manufacturing moulding and be stitched into bag, well-known.But the bag of cement papery is coarse, accompanies fibrage again in the middle of two layers of paper, and bag of cement also has different size, therefore is badly in need of its special-purpose cutting machine of research in the big production of bag of cement, and to the rare report of bag of cement special equipment.As Chinese patent application: 87215557 " glass zero twisted yarn refinforced cement coated paper envelope and process equipments thereof ", only refer to " cutting device (15) is the traction cutting mechanism ", " cut, become single bag base ", diagram is very simplified.Chinese patent application: 93218206.2 " cement packing compound paper bag Bag Making Machines " are also only said " through entering cutting mechanism (9) behind the draw-gear (8), cutting into single paper bag base only ", and figure also has only schematic diagram.Another part Chinese patent application: 87206427 " shears of cement package bags system machine " have been introduced its shear, it mainly is the improvement of cutting knife and Cutter apron structure, have and cut and cut two functions, reliably, the life-span is long, be used to make the shearing of fiber composite cloth, multilayer wood pulp brown paper, nonwoven cement package bags tube, more former cutting knife improves service time more than 6 times.But, with other mechanical relation, how to cooperate, turn round and but do not introduce its long continuously cement packing tube.

The purpose of this utility model is to provide a kind of and places on the production line, provides power by a motor, drives cutting knife with connecting rod, utilizes photo-electric control, makes cut-out accurate, stable, and consumption power is few, the fiber composite bag of cement shearing device of compact conformation.

The utility model can realize with the following method,

This device device on board has guide pulley, damping roller, conveying roller, cutting knife, bundle vent needle, board underlying buncher, connecting gear.Behind guide pulley, also be provided with the Photoelectric Detection head, at the fixed cutting tool that is provided with behind the conveying roller under reciprocal slide block, motion cutting knife and the board.Its motor is an electromagnetic adjustable speed motor, and the chain transmission connects active transportation roller, conveyer belt and linkage by ratio wheel.

The utility model can also be realized with the following method:

This device chat and the Photoelectric Detection head connect and control electromagnetic clutch (13), (14) electromagnetic brake (15), (16) by circuit.

In the linkage, the ratio wheel sprocket wheel is connected and fixed cranked driving wheel, is fixed with connecting rod on the crank, and connecting rod connects slide block, is fixed with the motion cutting knife on the slide block, also is connected with and pricks vent needle and spring, and the spring lower end is fixed with pressing plate, is fixed with fixed cutting tool under the board.

The utility model has following advantage compared to existing technology: this shearing device cooperates compactness on the production line of continuous production paper bag for cement, front and back are synchronous.With the action of photoelectric tube control cutting knife, stable, reliable, accurate.Because this device is only with a motor, and conveying and the staggered action of cut-out, consumption of power is few, energy savings.

Accompanying drawing drawing of the present utility model is described as follows:

Fig. 1 is the total structure schematic diagram of the utility model shearing device;

Fig. 2 is the transmission system schematic diagram of the utility model shearing device;

Do further narration below in conjunction with accompanying drawing:

The total structure figure of this device such as Fig. 1, its mechanical action process is: it is to impel paper bag not produce fold that rectangular composite fibre paper bag for cement enters 3 its effects of damping roller through guide pulley 2.Be printed with the colour code sign on the printing equipment in front on the paper bag, after the sensor of Photoelectric Detection 4 is received the colour code signal, promptly export control signal, by electromagnetic brake 15, make active transportation roller 5 related driven conveying rollers 6, stop operating, and original driving wheel 18 of stopping transport moves owing to unclamping electromagnetic clutch 13, by crank 17 drivening rods 19, slide block 7 is moved down from highest position, be connected in spring 21 on the slide block 7 and drive pressing plates 22 and press down and push down the rectangular paper bag for cement that desire is cut off, slide block 7 continues to move down, drive motion cutting knife 8, with the fixed cutting tool 9 that is fixed on the board 1, cement bag paper is cut off in acting in conjunction, meanwhile, the bundle vent needle 20 that is fixed on the slide block 7 also falls, and paper bag for cement is made passage.Cut fiber composite bag of cement is transported to subsequent processing through conveyer belt 12.When cut-out is finished, crank 17 is in lowest order just, when crank rises again, with lifting playback on the slide block 7, when crank 9 reaches highest order, by electromagnetic clutch 13 dead electricity, driving wheel 18 is lived in electromagnetic brake 16 brakings, electromagnetic clutch 14 gets electric work simultaneously, unclamps electromagnetic brake 15 and makes conveying roller 5, driven conveying roller 6 moving commentaries on classics, carries the paper bag for cement that next time need cut off.The Photoelectric Detection head begins to seek next place's colour code, begins new cycle operation again.

In order to measure colour code exactly, Photoelectric Detection 4 is fixed on the board 1, and the Photoelectric Detection head connects and control

electromagnetic clutch

13,14 and

electromagnetic brake

15,16 by circuit.Slide block 7 moves up and down at the slideway (figure does not draw) that is arranged on the board on 1, its center line extended line is by the center line of driving wheel 18, fixing motion cutting knife 8 on the slide block 7, prick vent needle 29, spring 21, be fixed with pressing plate 22 on the spring, fixed cutting tool 7 is fixed on the board 1 corresponding to motion cutting knife 8 devices.

The utility model only adopts an electromagnetic adjustable speed motor 10, by central shaft 23, is connected with electromagnetic clutch 13 respectively and acts on driving wheel 18 and be connected with electromagnetic clutch 14 and act on driving shaft 24.Central shaft also connects the transmission belt wheel, constantly carries the bag of cement that cuts off moulding.Because the active transportation roller 5 and driving wheel 18 alternating movements that are connected shearing device of paper bag for cement are carried in circuit control, therefore, motor can select for use consumed power lower, and power consumption is little, has saved power consumption naturally.

According to technological design and mechanical action requirement, those skilled in the art can be finished the Electromagnetic Control design of this shearing device, and this patent is not done argumentation.
