Technical field
The invention belongs to a technical field of toilet paper processing industry machinery.
Background technology
Toilet paper is the sanitary equipment be unable to do without in people's daily life.Owing to toilet paper there being the cause of several rows of aperture, so people when needed, can tear one piece another piece like a cork from defending row paper ball, neatly and cleanly having the shape of a real square toilet paper uses.But toilet paper does not have hole when production line gets off, in order to be convenient to tear fracture in use, generally all on toilet paper, row's aperture to be stamped every 10-15 centimetre when rewinding.This procedure expert named punching.In prior art, punching is all come by toilet paper perforating device on rewinding machine.Toilet paper perforating device, primarily of composition such as punching rotor, bed plate etc., punching rotor is provided with perforating knife, and the below of punching rotor is provided with bed plate, as shown in Figure 1.During machine operation, the tension force that health paper slip produces due to winding roll and be close to the knife edge of bed plate.Punching rotor is equipped with and makes also cutter, when punching rotor rotates under driven by motor, the knife edge of perforating knife intersects (collide, contact) with the knife edge of bed plate.The knife edge due to perforating knife is not continuous print straight line, and it is made up of the segment absolutely continued.Therefore the knife edge of perforating knife and the knife edge of bed plate crossing time health paper slip can't be interrupted, but beat the aperture of next row instantaneously on it.This completes the operation of toilet paper punching.
Toilet paper is book very, only has several millimeter at zero point, also wants book than common common paper.In order to guarantee to get evenly and also clearly hole row, punching rotor and bed plate all must have enough rigidity (non-deformability).So just propose a higher requirement to machine, that punch exactly rotor and bed plate all want thick very heavy, and rigidity is not good enough slightly else if, then drilling quality is without guarantee, even cannot get qualified hole.Be due to toilet paper very book equally, the adjustable precision of such structure, requirement must much smaller than the thickness of toilet paper.It is very very difficult that the straight line of a length about about one meter will reach such requirement.Such structure needs its rotation of driven by motor on the other hand, and the energy that in fact it need is also few, and that is such structure efficiency is very low, and most electric energy has been wasted in the wearing and tearing of machinery.
Summary of the invention
In order to deficiencies such as gram existing toilet paper perforating device are heavy, adjustment difficulty is high, efficiency is low, this invention takes the measure driving perforating knife with the motor that solenoid actuated perforating knife replaces under prior art.Its concrete structure is: perforating knife is movably arranged in frame 1, hilt 8 is equipped with in the end, both sides of perforating knife 2, pull bar 7 hilt 8 is equipped with, pull bar 7 is through the upper core 11 connected behind the hole on rob support 5 on electromagnet, and pull bar 7 has been threaded adjusting nut 6 between adjusting nut 6 and rob support 5, spring 9 is housed.Rob support 5 is fixedly mounted in frame 1, and spring 9 holds up perforating knife 2 by adjusting nut 6, pull bar 7 and hilt 8.Electromagnet coil 10 and lower core 12 are equipped with in the below of upper core 11, and electromagnet coil 10 and lower core 12 are fixedly mounted in frame 1, leave that gap moves up and down for perforating knife 2 between upper core 11 and lower core 12.Electromagnet coil 10 connects pulse signal generator.
The benefit done like this be the campaign of punching up and down of perforating knife 2 by solenoid actuated, enormously simplify the structure of perforating device, reduce adjustment difficulty, improve power utilization rate, saved electric energy and alleviated the weight of perforating device.The present invention simultaneously, at the punching number of the toilet paper of unit length, depends on the frequency of impulse generator, the interval width of also i.e. pulse.The frequency of regulating impulse is easy and convenient more than the rotating speed changing punching rotor, and can arbitrarily easily regulate at any time.This is the performance not available for existing perforating device.

detailed description of the invention
In order to deficiencies such as gram existing toilet paper perforating device are heavy, adjustment difficulty is high, efficiency is low, this invention takes and replace with solenoid actuated perforating knife the measure that existing motor drives perforating knife.Because the thickness of toilet paper only has a few tenths of a mm, the stroke (about 0.5mm) of toilet paper perforating knife is as long as the thickness being greater than slightly toilet paper can reach requirement.Electromagnet have structure simple, be swift in motion, drive easy, with low cost, action easy to adjust easily etc. many excellent.Therefore, electromagnet is particularly suitable for for driving toilet paper perforating knife.The electromagnet that the present invention uses is formed primarily of upper core 11, electromagnet coil 10, lower core 12; The technical requirement of toilet paper punching is in fact very low, as long as the knife edge of perforating knife is punched toilet paper facing to the knife edge of bed plate, gets final product eyeletting.As long as therefore perforating knife has small amount of exercise and the result of motion can be made to be that two knifes edge intersect and can achieve the goal.This programme is movably arranged on perforating knife in frame for this reason." flexible connection " described here, refers to that perforating knife can be done suitably dynamic relative to frame and bed plate, the annexation that the result of motion can make two knifes edge intersect.The frame mode that can realize this annexation is a lot, such as, by using the articulated manner of rocking arm, using mode etc. of fitting a straight line of guide rail or buckle; The concrete structure of this example is: perforating knife is movably arranged in frame 1, frame 1 has an elongated hole slightly higher than perforating knife, the effect of elongated hole is equivalent to guide rail, it is only permitted perforating knife has and moves left and right and limited two frees degree that move up and down, and upper and lower range of movement regulates by stroke regulating screw 15.Hilt 8 is all equipped with in the end, both sides of perforating knife 2, and hilt 8 has been threaded pull bar 7, and pull bar 7 is through the upper core 11 connected behind the hole on rob support 5 on electromagnet.Rob support 5 is fixedly mounted in frame 1.Pull bar 7 is through behind the hole of rob support 5, and the free degree of perforating knife 2 is just only left upper and lower two limited frees degree.Pull bar 7 has been threaded adjusting nut 6 between adjusting nut 6 and rob support 5, spring 9 is housed.Spring 9 holds up perforating knife 2 by adjusting nut 6, pull bar 7 and hilt 8.The effect of spring 9 is exactly the weight overcoming perforating knife, and perforating knife 2 is held up, and allows health paper slip 13 pass through, as shown in Figure 2.Its dynamics held up regulates by adjusting nut 6.Electromagnet coil 10 and lower core 12 are equipped with in the below of upper core 11, and electromagnet coil 10 and lower core 12 are fixedly mounted in frame 1, leave that gap moves up and down for perforating knife 2 between upper core 11 and lower core 12.Electromagnet coil 10 connects pulse signal generator.
The course of work of the present invention is: before start, and the knife edge of perforating knife leaves an interspace under the effect of spring 9 to be passed through for health paper slip 13 with the knife edge of bed plate 4, as shown in Figure 2.After start, winding roll 14 starts coil paper, health paper slip 13 therefore create certain tension force and the knife edge being close to bed plate 4 with certain speed by the gap between the knife edge of perforating knife 2 and bed plate 4 knife edge.At this moment pulse signal generator often sends pulse current to electromagnet coil 10 at regular intervals.When electromagnet coil 10 have pulse current by time just create electromagnetic force, pull pull bar 7, hilt 8 and perforating knife 2 downwards by upper core 11.The knife edge of perforating knife and bed plate two cutter is intersected, and result gets row's aperture.Because the time span of electric pulse is very narrow, punching has just completed and has just rapidly disappeared.After current vanishes, electromagnet also loses magnetic force, and perforating knife upwards rises under the effect of spring 9, allows toilet paper continue through.After certain hour, pulse signal generator sends pulse current again, and machine repeats said process again.If change the punching quantity (pitch-row or Kong Mi) of toilet paper unit length, as long as the frequency of regulating impulse.
