The present invention relates to a corrugating machine, and more particularly to a corrugating machine, with which at least three plies of work material may be rolled using two rolling mechanisms of the corrugating machine to form desired corrugations and bond together to thereby provide enhanced structural strength and improved damping effect.
Generally, a conventional corrugated paper forming machine includes a plurality of rolls, a glue dispensing device, a heating device, and a conveying device, so that two webs of paper are continuously supplied into the machine to be roll formed, glued, bonded, dried, and finally conveyed out of the machine to provide a finished product of single corrugated board.
While the conventional corrugated paper forming machine may be used to produce a single corrugated board from two webs of continuous paper, only one of the two webs of paper can be rolled to form desired corrugation thereon and then bonded to the other web of paper to complete a single corrugated board. Therefore, an article made of the single corrugated board so produced with the conventional corrugating machine has relatively low structural strength and damping effect, and might not be strong enough in practical use thereof.
A primary object of the present invention is to provide a corrugating machine, so that at least three plies of work material may be rolled using two rolling mechanisms of the corrugating machine to form desired corrugations and bond together to thereby provide enhanced structural strength and improved damping effect.
To achieve the above and other objects, the corrugating machine according to the present invention includes a bed; a first rolling mechanism arranged on one side of the bed, and including a plurality of longitudinal flute forming roll sets, each of which includes two vertically correspondingly arranged rolls; and a second rolling mechanism arranged on another side of the bed opposite to the first rolling mechanism, and including a corrugating roll, a transverse flute forming roll and a toothed roll respectively located at an upper and a lower position at one side of the corrugating roll facing toward the first rolling mechanism to mesh with the corrugating roll, a glue spraying unit located between the corrugating roll and the transverse flute forming roll, and a smooth roll and an adhesive dispensing unit respectively located at an upper and a lower position at another side of the corrugating roll facing away from the first rolling mechanism.
The structure and the technical means adopted by the present invention to achieve the above and other objects can be best understood by referring to the following detailed description of the preferred embodiments and the accompanying drawings, wherein
Please refer to
The bed 1 may be connected to a front-end and a rear-end process (not shown) depending on actual need.
The first rolling mechanism 2 is arranged on one side of the bed 1, and includes at least a plurality of longitudinal flute forming roll sets 21 each of which includes two vertically correspondingly arranged rolls and is provided with a cooperative adjusting unit 22.
The second rolling mechanism 3 is arranged on another side of the bed 1 opposite to the first rolling mechanism 2, and includes at least a corrugating roll 31, a transverse flute forming roll 32 and a toothed roll 33 respectively located at an upper and a lower position at one side of the corrugating roll 31 facing toward the first rolling mechanism 2 to mesh with the corrugating roll 31, a glue spraying unit 34 located between the corrugating roll 31 and the transverse flute forming roll 32, and a smooth roll 35 and an adhesive dispensing unit 36 respectively located at an upper and a lower position at another side of the corrugating roll 31 facing away from the first rolling mechanism 2.
The adhesive dispensing unit 36 includes a tank 361 for containing an amount of adhesive therein, and an adhesive dispensing roll 362 and an adhesive scraping roller 363 correspondingly arranged in the tank 361 to contact with each other.

When the bed 1 is actuated for the first and the second rolling mechanism 2, 3 to operate, the first work material 4 passed through the longitudinal flute forming roll sets 21 is rolled to form longitudinal flutes 41 thereon, as shown in
The longitudinally fluted first work material 4 is kept moving forward to first pass between the toothed roll 33 and the pulley 332 and then passes between the toothed roll 33 and the corrugating roll 31. Meanwhile, the transversely fluted second work material 4a passes the glue spraying unit 34 and is coated with a layer of glue before moving forward to pass between the toothed roll 33 and the corrugating roll 31. Therefore, the first work material 4 with the longitudinal flutes 41 and the second work material 4a with the transverse flutes 41a overlap each other between the toothed roll 33 and the corrugating roll 31 and are bonded together under the roll pressure from the two rolls 33 and 31.
Meanwhile, due to the tapered teeth 331 on the roll surface of the toothed roll 33, the first and the second work materials 4, 4a bonded together between the rolls 33 and 31 are embossed at the same time to form a plurality of tapered protrusions 42 thereon, as shown in
The bonded and embossed first and second work material 4, 4a is kept moving forward to pass the adhesive dispensing roll 362 of the adhesive dispensing unit 36 and be coated with a layer of adhesive before moving into a clearance between the corrugating roll 31 and the smooth roll 35. Meanwhile, the third work material 4b is moved forward to pass between the corrugating roll 31 and the smooth roll 35 and thereby bonded to the previously bonded, embossed, and adhesive coated first and second work material 4, 4a, as shown in
The fully bonded first, second, and third work material 4, 4a, 4b is then subjected to subsequent drying and winding process (not shown) to thereby provide an enhanced structural strength and improved damping effect.
With the above arrangements, the corrugating machine of the present invention effectively overcomes the drawbacks in the prior art by using first and second rolling mechanisms to roll, flute, corrugate, and bond at least three plies of work material, so that the finally produced material has enhanced structural strength and improved damping effect to ensure practical and valuable use thereof.
