The specific embodiment
In order further to explain technical scheme of the present invention, below by specific embodiment, the present invention will be described in detail.
As shown in Fig. 1 to 7, a kind of nonwoven cloth punching apparatus of the present invention, comprises unreeling shaft 1, deflector roll 2, grooved roll 3, perforating mold 4, cold formed roller 5, cutting roller 6, cutting part 7, Scroll 8 and frame 9.
One of main improvement of the present invention is the concrete structure of grooved roll 3 and perforating mold 4.The cylindrical structure that grooved roll 3 is hollow, is provided with heating rod and is filled with heating oil in grooved roll 3, by heating rod, make heat by heating oil, be delivered to the surface of grooved roll 3.One-body molded on the periphery of grooved roll 3 have a multi-turn groove.
Perforating mold 4 is also the cylindrical structure of hollow, is provided with heating rod and is filled with heating oil in perforating mold 4, by heating rod, is heated to 140 degree to 160 degree, makes heat by heating oil, be delivered to the surface of perforating mold 4, realizes punching HEAT SETTING.One-body molded on the periphery of perforating mold 4 have a multi-turn spine 41, two adjacent rings spine 41 setting of mutually staggering.Perforating mold 4 and grooved roll 3 is corresponding to be arranged, on perforating mold 4 respectively enclose spine 41 respectively the groove 31 that respectively encloses on respective slot roller 3 arrange.Spine 41 adopts bore spine, frustum or needling structure.Multi-turn spine 41 is arranged in parallel, and multi-turn groove 31 is also arranged in parallel.
Distance between axles between perforating mold 4 and grooved roll 3 is adjustable, distance between axles between perforating mold 4 and grooved roll 3 is larger, spine 41 punctures nonwoven cloth cover after nonwoven cloth cover to puncture the distortion at place also less, and the punching line on nonwoven fabric is also just fuzzyyer, and the feel of perforated non-woven fabric is also just more soft.Otherwise the distance between axles between perforating mold 4 and grooved roll 3 is less, spine 41 punctures nonwoven cloth cover after nonwoven cloth cover to puncture the distortion at place also larger, and the punching line on nonwoven fabric is also just more clear, and the feel of perforated non-woven fabric is also just harder.
As a preferred embodiment of the present invention, spine 41 is frustum, the end face diameter of spine 41 is 0.5mm, spine 41 is about 3.7mm, and the root diameter (RD) of spine 41 is about 1.5mm, and the end face sum of multi-turn spine 41 accounts for the face of cylinder approximately 20% of perforating mold 4, punching effect is comparatively desirable like this, for atresia nonwoven fabric, the feel of perforated non-woven fabric is more soft, and laminating dermal sensation is very comfortable.
Cold formed roller 5 be axially arranged with a blower, the air outlet of blower axially arranges along cold formed roller 5, by blower face toward punching nonwoven face on cold formed roller 5 blow cooling, thereby reach cold formed object.
Cutting part 7 comprises installing rack 71, knife rest 72, cutter 73 and motor, the relative cutting roller 6 of installing rack 71 arranges, knife rest 72 is arranged on installing rack 71 in the mode that can adjust by securing member, motor is arranged on knife rest 72, the rotating shaft of motor connects cutter 73, cutter 73 adopts cylinder blade structure, and cutter 73 arranges perpendicular to cutting roller 6.
In addition, the adjustable mounting means of activity between knife rest 72 and installing rack 71 also can adopt following structure: between knife rest 72 and installing rack 71, by suitable slide block and slide rail, be assembled together, by securing member (bolt etc.), knife rest 72 be fastened on installing rack 71.
As another preferred embodiment of the present invention, cutting part 7 is a plurality of, and a plurality of cutting parts 7 are laid along the axis of cutting roller 6.For example along the axis of cutting roller 6, lay 3,5 or 8, thereby the nonwoven fabric of walking around cutting roller 6 is cut to correspondence, be slit into 4,6 or 9.In addition, the importing of cutting roller 6 and derivation place are respectively equipped with cutting guide roller 61.
As a preferred embodiment more of the present invention, the present invention also comprises rolling torque motor and winding tension automatic controller, and the output of winding tension automatic controller connects the control end of rolling torque motor, and the rotating shaft transmission of rolling torque motor connects Scroll 8.Winding tension automatic controller is according to the initial diameter before Scroll 8 rollings and the relevant parameters such as final diameter after rolling, by controlling the electric current of rolling torque motor, control the moment of torsion of rolling torque motor, thereby reach the object of the constant tension of the perforated non-woven fabric on Scroll 8.Due to the constant tension of the perforated non-woven fabric on Scroll 8, the shrinkage degree of perforated non-woven fabric remains that unanimously, the fabric width of perforated non-woven fabric is consistent like this, can not produce contracting width phenomenon.
In addition, unreeling shaft 1 also can adopt as above structure, for example comprise and unreel torque motor and unwinding tension automatic controller, the output of unwinding tension automatic controller connects the control end that unreels torque motor, the rotating shaft transmission that unreels torque motor connects unreeling shaft 1, thus the constant tension of nonwoven fabric while realizing unreeling shaft 1.Unreel motor and winding motor and adopt respectively servo drive motor structure.
In addition, between unreeling shaft 1 and grooved roll 3, and be respectively arranged with deflector roll 2 between cold formed roller 5 and cutting guide roller 61.The quantity of deflector roll 2 can be set according to the concrete condition of production line, for example, 2 deflector rolls 2 are set between unreeling shaft 1 and grooved roll 3, between cold formed roller 5 and cutting guide roller 61,3 deflector rolls 2 are set, the setting of staggering up and down of these 3 deflector rolls 2, perforated non-woven fabric is snakelike and from then on 3 deflector rolls 2, walks around.
During production, atresia nonwoven fabric roll 1a is arranged on unreeling shaft 1, the leftover of bolt of cloth of atresia nonwoven fabric roll 1a is snakelike deflector roll 2 and the grooved roll 3 walked around successively, during through perforating mold 4, form perforated non-woven fabric, perforated non-woven fabric realizes punching HEAT SETTING by the heating rod in perforating mold 4 and grooved roll 3, and the perforated non-woven fabric after HEAT SETTING realizes cooling and shaping by blower while passing through cold formed roller 5.Perforated non-woven fabric after cooling and shaping is walked around cutting guide roller 61, cutting roller 6 and another cutting guide roller 61 successively, and perforated non-woven fabric is cut into many, is finally received in and on Scroll 8, forms multireel perforated non-woven fabric volume 2a.
Above-described embodiment and accompanying drawing non-limiting product form of the present invention and style, suitable variation or modification that any person of an ordinary skill in the technical field does it, all should be considered as not departing from patent category of the present invention.
