One kind rolls point contact and scrapes cut type disconnecting device
Technical field
The present invention relates to the cutting technique field of the disposable sanitary articles material such as non-woven fabrics and dust-free paper, is specially one kind
Roll point contact and scrape cut type disconnecting device.
Background technology
In wet tissue production process, it is necessary to the wet tissue that can just produce and be sized for using is cut off to non-woven fabrics, at present
For most manufacturing machine using roll-turning cloth-cutting apparatus, roll-turning cloth-cutting apparatus is the relative rotation by upper and lower two rotors
Make upper cutter and lower cutter when meeting, produce larger extruding force on a line of cutter contact, moment to non-woven fabrics into
Row cut-out, such device have the disadvantage that:First, roll-turning disconnecting device, in cutting-off process, two rotor moments produced
Larger extruding force is, it is necessary to high-power driving motor;Second, cutter direct collision extruding is cut off by keen edge degree, knife is be easy to cause
Sharpening damage and damage, cutter life are short;Third, the blade requirement installation gap precision of installation is higher in upper and lower rotor, blade
Quick abrasion, repetition reconditioning frequency is higher, not easy to operate;Four pollutions of collision noise when being turned off are big, are unfavorable for operating the body of employee
Heart health.For this reason, it is proposed that a kind of point contact that rolls scrapes cut type cloth-cutting apparatus.
The content of the invention
Point contact is rolled it is an object of the invention to provide one kind and scrapes cut type disconnecting device, to solve in above-mentioned background technology
The problem of proposition.
To achieve the above object, the present invention provides following technical solution:One kind rolls point contact and scrapes cut type disconnecting device, wraps

Knife (2), the lower rotor (3) are equipped with lower cutter (4), and the upper cutter is scraper, and upper cutter (2) is set with upper rotor (1)
For relative tilt structure, the lower cutter is vertically set on lower rotor, the center line of the lower rotor (3) and upper rotor (1)
It is tilted a certain angle with vertical direction in the horizontal direction from lower rotor one end to the other end, lower cutter is started at from peak
An angular range in upper cutter continuously scrape cut type point contact.
Getter device is equipped with the lower rotor (3), the side of the lower rotor (3) is equipped with to be connected with getter device air inlet
Logical suction hole.
The upper cutter (2) sets quantity no less than two and is evenly distributed on rotor (1), the lower cutter with it is upper
The quantity of cutter is identical and corresponds.
The rack includes base, and base (10) upper end is equipped with location hole (11), is additionally provided with the base (10)
Middle riser (8), motor (9) and supporting rack (12), the motor (9) is located between supporting rack (12) and middle riser (8), in described
Riser (8) is equipped with two and is set in front-end geometry, the lower rotor axis horizontal and by two end axles bearing be fixed on it is front and rear in
Between the corresponding surface of riser (8), the upper rotor by eccentric adjustment be arranged on it is front and rear in riser (8) corresponding surface it
Between, the motor (9) is connected with upper rotor, lower rotor by transmission mechanism.
Upper rotor (1) both ends coordinate with eccentric adjustment (13) installs.
The eccentric adjustment (13) is by adjusting center bearing, eccentric disc (131), eccentric adjusting seat (132) and eccentric tune
Whole handle (133) is formed, and the eccentric disc (131) is embedded in the endoporus of eccentric adjusting seat (132), the eccentric disc (131)
Endoporus is centering type, and the adjusting center bearing is installed on eccentric disc endoporus and is sleeved on rotor both ends, the eccentric adjustment handle
(133) it is fixed on the side of eccentric adjusting seat (132).
The side of the lower rotor is additionally provided with folding rotor, the upper rotor (1), lower rotor (3), fold rotor (6) into
Delta structure is set, and the lower rotor (3) and folding rotor (6) are in mutually from setting, the upper rotor (1) and folding rotor
(6) gap is equipped between, the upper rotor (1), lower rotor (3), folding rotor (6) are connected by synchromesh gear, the lower knife
Roller (3) is equipped with plug cloth knife, and the slightly prominent lower rotor surface of the plug cloth knife, the plug cloth knife is nylon blade, the jackknife
Roller is equipped with folder cloth knife, and the plug cloth knife is corresponded with folder cloth knife.
The lower cutter (4) and plug cloth knife (5) set quantity to be no less than two and settings that be interspersed, described to press from both sides cloth knife
(7) in a ring structure setting and set quantity be no less than two.
Compared with prior art, the beneficial effects of the invention are as follows:The rolling point contact scrapes cut type disconnecting device, upper cutter with
The place of the opposite contact of lower cutter is in the angular range started at from peak, due to the center of lower rotor and upper rotor
Line is tilted a certain angle with vertical direction in the horizontal direction from lower rotor one end to the other end, and suitable position is moved in lower cutter
When putting, there is a contact point with upper cutter non-inclined end, if lower cutter is rotated to side, lower cutter is gradually horizontal and perpendicular
Nogata is inclined at the point that the upper cutter on rotor is vertically oriented to and is also gradually moved in horizontally and vertically direction to movement
It is dynamic, it can realize that the knife-edge elastic force continuity of the acute angle and upper cutter of lower cutter is scraped and cut, the collision friction of cutter be avoided, so that greatly
Big to improve cutting-tool's used life, cutting-tool's used life limitation is only merely the wear extent of upper slitter, cutter life
Improve more than 100,000 times;When non-woven fabrics is transported to cutter part, lower rotor is equipped with air intake device, can tightly inhale non-woven fabrics
It is attached on lower rotor surface and lower cutter, non-woven fabrics is run simultaneously with lower rotor, and upper cutter inverted running, go in the same direction point contact
Scrape cutting, the non-woven fabrics cut is sent on the folder cloth knife folded on rotor after progress by the plug cloth knife on lower rotor and is located
Reason.Lower rotor is parallel with lower cutter and with the perpendicular position relationship of non-woven fabrics, upper cutter is presented around the axle center of upper rotor
Spiral shape position relationship somewhat, the radial direction out of plumb of upper rotor and lower rotor is axial not parallel, when opposite direction rotating is run above and below
Cutter initial contact point and eventually off point are not the same time, it is achieved thereby that point contact scrapes disconnected function, the both ends of upper rotor
It is two independent eccentric adjustments to fix.The contact distance of upper lower cutter is kept constant unanimously, by upper from beginning to end
The off-center adjustment apparatus at rotor both ends corrects contact distance of the upper slitter with lower knife.
Point contact scrapes butt formula, avoids cutter collision and improves cut quality, ensures that cut surface hangs down with design on fabric surface
Direct join and the filament not cut off will not be remained, prevent similar cutting phenomenon separated but still in each other's thoughts completely, thus have stability it is good,
The characteristics of durability is high, noise is small, the present apparatus use driving power of motor significantly to reduce, energy conservation and environmental protection, present apparatus upper slitter
Roller and lower rotor are respectively provided with much knives, and upper cutter and lower cutter correspond, and rotor, which turns around, can cut repeatedly, cutting effect
Rate is high.
