Description

Technical Field

[0001] This utility model relates to corrugated cardboard processing equipment, and in particular to a single-face corrugating machine. Background Technology

[0002] Single-face corrugating machines are used to produce single-sided corrugated paperboard with one flat sheet and one corrugated sheet. After the corrugated paper is formed, it is bonded to the base paper. A paperboard processing equipment with oblique corrugated teeth is proposed to press the flat sheet and one corrugated sheet of two sets of single-face corrugating machines together to obtain four-layer tip-to-tip corrugated paperboard without core paper and can adapt to heavy-duty scenarios. Utility Model Content

[0003] In view of the technical problems existing in the background art, the present invention aims to provide a single-face corrugating machine, which is designed with the first protrusion and the second protrusion inclined relative to each other along the axial direction, for producing corrugated paper with oblique corrugated teeth.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: This single-sided corrugating machine includes a corrugated paper forming mechanism and a bottom paper bonding mechanism. The corrugated paper forming mechanism is connected to the bottom paper bonding mechanism. The corrugated paper forming mechanism includes a first corrugated roller and a second corrugated roller that cooperate with each other. The first corrugated roller is provided with first protrusions spaced apart along the circumference, and the second corrugated roller is provided with second protrusions spaced apart along the circumference. The second protrusions are inserted between the first protrusions. The first protrusions are inclined relative to the axial direction, and the second protrusions are inclined relative to the axial direction and symmetrical with the first protrusions in the axial direction.

[0005] In this design, the first and second protrusions engage to form oblique corrugated teeth in the corrugated paper.

[0006] Preferably, the backing paper bonding mechanism includes an adhesive application assembly, a pressure roller, and a pressing belt. The diameter of the pressure roller is larger than the diameter of the first corrugated roller. The pressing belt is arranged circumferentially along the pressure roller and is wound around a pulley assembly.

[0007] In this scheme, the pressing belt and the pressure roller continuously press the corrugated paper teeth and the bottom paper, requiring less pressing force, and the bottom paper will not have indentations due to excessive pressing force.

[0008] Preferably, the second corrugated roller, the adhesive application assembly, and the pressure roller are sequentially arranged along the circumference of the first corrugated roller.

[0009] In this scheme, the first corrugated roll, together with the pressure roll, pre-presses the corrugated paper tips and the bottom paper to achieve initial bonding.

[0010] Preferably, the pressure roller is equipped with a heating component.

[0011] In this solution, the heating component creates a high temperature on the surface of the pressure roller to heat and cure the adhesive.

[0012] Preferably, the pulley assembly includes a paper feed roller and a paper output roller, the paper feed roller being mounted on a mounting plate, and the mounting plate being oscillating.

[0013] In this design, the mounting plate swings to move the paper feed roller away from the pressure roller, making it convenient to introduce the corrugated paper and base paper between the pressing belt and the pressure roller during debugging.

[0014] Preferably, the pressure roller is positioned above the first corrugated roller, and the pulley assembly includes a tensioning pulley, which is horizontally adjustable.

[0015] In this scheme, the tensioning wheel moves horizontally to adjust the tension of the pressing belt.

[0016] Preferably, both the paper feed roller and the paper output roller have a paper passage gap with the pressure roller.

[0017] In this solution, the pressure during paper feeding and output is low, which will not create indentations on the backing paper and also facilitates the feeding and output of materials of different thicknesses.

[0018] Preferably, the pulley assembly further includes a pressure pulley, which is disposed at one end of the mounting arm. The mounting arm is hinged to the frame, and an elastic element is connected to the other end of the mounting arm.

[0019] In this scheme, when a flat sheet and a corrugated sheet pass through the pressure roller, they are subjected to pressure and are pressed together before being discharged to ensure reliable bonding.

[0020] The beneficial effects of this utility model are as follows: the first and second protrusions engage to form oblique corrugated teeth on the corrugated paper; the pressing belt, in conjunction with the pressure roller, continuously presses the tips of the corrugated paper teeth and the base paper, requiring less pressing force and preventing indentations on the base paper due to excessive pressing force; the first corrugated roller, in conjunction with the pressure roller, performs a pre-pressing of the tips of the corrugated paper teeth and the base paper. Therefore, this utility model has substantial features and progress compared with the prior art. Attached Figure Description

[0028] See appendix Figure 1-2 In one embodiment of this invention, a single-sided corrugating machine includes a corrugated paper forming mechanism 1 and a bottom paper bonding mechanism 2. The corrugated paper forming mechanism 1 is connected to the bottom paper bonding mechanism 2. The corrugated paper forming mechanism 1 includes a first corrugated roller 3 and a second corrugated roller 4 that cooperate with each other. The first corrugated roller 3 is provided with first protrusions 5 at intervals along the circumference, and the second corrugated roller 4 is provided with second protrusions 6 at intervals along the circumference. The second protrusions 6 can extend into the spaces between the first protrusions 5.

[0029] The first protrusion 5 is inclined relative to the axial direction, and the second protrusion 6 is inclined relative to the axial direction and is symmetrical to the first protrusion 5 in the axial direction.

[0030] The backing paper bonding mechanism 2 includes an adhesive application assembly, a pressure roller 7, and a pressing belt 8. The diameter of the pressure roller 7 is larger than the diameter of the first corrugated roller 3. The pressing belt 8 is arranged circumferentially around the pressure roller 7 and is wound around the pulley group 9. The second corrugated roller 4, the adhesive application assembly, and the pressure roller 7 are arranged sequentially along the circumference of the first corrugated roller 3. The pressure roller 7 is equipped with a heating assembly.

[0031] In this embodiment, the first protrusion 5 and the second protrusion 6 engage to form the oblique corrugated teeth of the corrugated paper. The gluing assembly applies glue to the oblique corrugated teeth. The base paper and the corrugated paper are pre-pressed between the pressure roller 7 and the first corrugated roller 3. After entering the pressing belt 8 and the pressure roller 7, they are continuously pressed. The pressing force is small, the pressing effect is good, and there are no indentations on the surface of the base paper. The gluing assembly applies glue to the oblique corrugated teeth or the base paper through the gluing roller, which is a mature technology. The heating assembly uses steam heating, hot oil heating, or electromagnetic heating, which is a mature technology. The mounting plate 12 is hinged to the frame 17 and to the cylinder output shaft. The cylinder output shaft extends and retracts, causing the mounting plate 12 to swing around the hinge point. The tension wheel 13 is connected to the adjusting block, and the adjusting block is threadedly engaged with the screw.

[0032] See appendix Figure 2 The pulley assembly 9 includes a paper feed pressure roller 10 and a paper output pressure roller 11. The paper feed pressure roller 10 is mounted on a mounting plate 12, which is oscillating. The pressure roller 7 is positioned above the first corrugated roller 3. The pulley assembly 9 includes a tension roller 13, which is horizontally adjustable. Both the paper feed pressure roller 10 and the paper output pressure roller 11 have a paper passage gap 14 with the pressure roller 7. The pulley assembly 9 also includes a belt pressure roller 15, which is mounted at one end of a mounting arm 16. The mounting arm 16 is hinged to the frame 17, and the other end of the mounting arm 16 is connected to an elastic element.

[0033] In this embodiment, during debugging, the mounting plate 12 drives the paper feeding pressure roller 10 to swing, increasing the paper passage gap 14 to facilitate the introduction of the bottom paper and corrugated paper. The tension roller 13 moves horizontally to adjust the belt tension, ensuring the conveying area with the material and reliable conveying. The compression degree of the elastic element can be adjusted to adjust the pressure of the pressure roller 15 to achieve the desired pressing effect.
