[0037] Referring to Figures 1 to 3 , the embodiment relates to a face paper splicing device of a corrugated board production equipment, including face paper frame 1 for placing face paper and rectifying machine 2 for rectifying face paper, face paper frame 1 is at least provided with two, and rectifying machine 2 rectifies the face paper output by at least one face paper frame 1, makes each face paper be mutually staggered and not overlapped along the width direction of face paper, and the lower edge of the upper face paper and the upper edge of the lower face paper in adjacent two face papers are aligned.
[0038] The face paper is installed in a roll on the face paper frame 1. The face paper frame 1 outputs the face paper through the paper jointer 3. After the face paper is input into the rectifier 2, the rectifier 2 rectifies the face paper, so that all the face papers are staggered and not overlapped in the width direction, and the adjacent two face papers are staggered and aligned with each other, that is, the lower edge 03 of the upper face paper C01 and the upper edge 04 of the lower face paper C02 of the adjacent two face papers are aligned with each other, so that all the face papers output from the rectifier 2 form face papers spliced in the width direction. The face paper spliced in the face paper and the single-side corrugated paper D after sizing are jointly input into the double-side machine to be attached, forming the corrugated paper E with spliced face paper. The device is used to solve the problem that the width size of the face paper and the production equipment cannot meet the requirement of the existing corrugated paper E with large width face paper.

[0039] The rectifier 2 is provided with a sensor for detecting the position of the face paper in the width direction, and an adjusting mechanism for adjusting the position of the face paper in the width direction. After the sensor detects the position of the input face paper in the width direction of the rectifier 2, the adjusting mechanism adjusts the position of the face paper, so that the adjacent two face papers are staggered in the width direction, and the lower edge of the upper face paper and the upper edge of the lower face paper in the adjacent two face papers are aligned. The rectifier 2 is a kind of existing equipment. The existing rectifier 2 is used to rectify only one face paper, so that the face paper is attached to the single-side corrugated paper D.

Similarly, when the width of the corrugated paper E required is greater than the width of two face papers but does not exceed the total width of three face papers, three face paper racks 1 are required. In this way, the number of the face paper racks 1 is determined.

[0053] In combination Figures 5 to 8As shown, the embodiment also provides a face paper splicing type corrugated paperboard production equipment, which comprises a corrugating machine 10, a pasting machine 30 and a double-sided machine 40, and further comprises the face paper splicing device 100 described above. The single-sided corrugated paper D processed by the corrugating machine 10 enters the double-sided machine 40 after being sized by the pasting machine 30. The face paper splicing device aligns the longitudinal edges of two or more face papers distributed transversely and then inputs them into the double-sided machine 40, so as to adhere the flutes of the single-sided corrugated paper D to the spliced face paper through the double-sided machine 40.
[0054] The output end of the double-sided machine 40 is further sequentially provided with a longitudinal cutter 50, a transverse cutter 60 and a stacking machine 70.

[0057] The working principle is that two face paper rolls are arranged transversely, and face paper is respectively fed from each face paper roll. The adjacent face papers are spliced by the face paper correcting machine 2 to align the longitudinal edges, and then are input into the double-sided machine 40 together with the sized single-sided corrugated paper D to perform adhesion, so as to form the face paper spliced corrugated paperboard E.
[0058] The corrugated paperboard E enters the longitudinal cutter 50, which cuts the paperboard according to the required length. Then the cut face paper spliced corrugated paperboard E is separated by the upper and lower transition frames 501, and is then sent to the corresponding upper transverse cutter group 61 and lower transverse cutter group 62 for cutting. Finally, the cut face paper spliced corrugated paperboard E is stacked by the stacking machine 70.
[0059] The embodiment also provides a splicing method of the face paper splicing device of the corrugated paperboard production equipment, and the specific content is as follows:
[0060] Each sheet paper holder 1 outputs sheet paper. At least one sheet paper output from sheet paper holder 1 is detected and corrected by the alignment machine 2, causing the sheet paper output from each sheet paper holder 1 to be staggered along the width direction of the sheet paper. The lower edge of the upper sheet of two adjacent sheet paper is aligned with the upper edge of the lower sheet, thereby increasing and expanding the width of the entire sheet paper after formation. The expanded sheet paper is then output to the heating device for heating, and then fed together with the sized single-sided corrugated paper D into the double-sided machine 40 for lamination, forming a corrugated board E with laminated sheet paper. The width of the entire sheet paper after formation is the sum of the widths of the sheet paper output from each sheet paper holder 1.
[0061] The corrugated cardboard E with the face paper spliced enters the slitting machine 50. The slitting machine 50 cuts the cardboard according to the required length. Then, the cut corrugated cardboard E with the face paper spliced is separated into upper and lower sections by the transition frame and then fed into the corresponding upper cross-cutting knife group 61 and lower cross-cutting knife group 62 for further cutting. Finally, it is stacked by the stacking machine 70.
[0062] This invention innovatively employs a method of splicing face sheets. A web-aligning machine 2 corrects the width of the face sheets, causing two or more sheets to be spliced together in width. This results in a face sheet with increased and expanded width, matching the dimensions of a large-width single-face corrugated paperboard D, thus enabling the production of large-width corrugated cardboard E. Therefore, this invention solves the problem that the width of existing single-face sheets cannot meet the requirements for producing large-width corrugated cardboard E. It has the advantages of ingenuity, convenient processing, and speed. Furthermore, the hardware and equipment used in this method are very simple; only the web-aligning machine 2 is needed to correct the added face sheets, aligning and splicing them in width to increase and expand the width of the face sheets, ensuring the width of the spliced face sheets matches the width of the single-face corrugated paperboard D, thereby producing the required large-width corrugated cardboard E.
[0063] The above-disclosed embodiment is merely a preferred embodiment of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
