[0034] In order to make the purpose, technical solutions, and advantages of the present disclosure more apparent, exemplary embodiments according to the present disclosure will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments of the present disclosure. It should be understood that the present disclosure is not limited by the exemplary embodiments described herein.

[0035] Please refer to Figures 1 to 3 , a sealing strip for plugging a ceramic panel vacuum one - chamber is proposed in the present disclosure. Among them, it includes a sealing strip body 1, and the sealing strip body 1 is arranged in the suction area of the ceramic panel vacuum one - chamber and is located between adjacent ceramic strip plates. The suction area of the ceramic panel vacuum one - chamber is the inlet of the ceramic vacuum box.

[0036] The side surface of the sealing strip body 1 has a shape that can fit with the side surface of the corresponding ceramic strip plate; specifically, a plurality of ceramic strip plates are arranged in parallel at the inlet of the ceramic vacuum box, and there is a gap between adjacent ceramic strip plates for air intake.

[0037] The number of the sealing strip bodies 1 is less than the number of the suction areas of the ceramic panel vacuum one - chamber and / or the length of the sealing strip is less than the length of the suction area of the ceramic panel vacuum one - chamber. That is, by plugging some of the inlets with the sealing strip body 1, that is, not plugging all the inlets completely, the air inlet becomes smaller, the air intake resistance increases, thereby reducing the vacuum degree of the ceramic panel vacuum one - chamber, and thus reducing the dehydration speed of the paper in the ceramic panel vacuum one - chamber.

[0038] According to one aspect of the present disclosure, the sealing strip body 1 includes a first sealing portion 11 and a second sealing portion 12. The first sealing portion 11 and the second sealing portion 12 have the same length and are integrally formed. The cross-section of the first sealing portion 11 is a right trapezoid; the cross-section of the second sealing portion 12 is a triangle; specifically, one side of the triangle coincides with the oblique waist of the right trapezoid, that is, one side surface of the first sealing portion 11 is attached to one side surface of the second sealing portion 12 to form an integral body. In practical applications, the first sealing portion 11 and the second sealing portion 12 can be a whole. The thickness of the second sealing portion 12 gradually decreases in the direction away from the first sealing portion 11.

[0039] According to another aspect of the present disclosure, on the cross-section of the sealing strip body 1, the included angle between the side of the triangle connected to the lower base of the right trapezoid and the lower base of the right trapezoid is 151 degrees. Specifically, when implemented, this angle is determined according to the specific structure of the ceramic strip board, and it is better to fit with the ceramic strip board.

[0040] According to another aspect of the present disclosure, a card slot 111 is provided on the side of the first sealing portion 11 away from the second sealing portion 12; and the opening of the card slot 111 faces away from the second sealing portion 12. The card slot 111 is used for clamping the support rod of the ceramic panel. In this way, the installation of the sealing strip body 1 can be facilitated.

[0041] According to another aspect of the present disclosure, the number of the card slots 111 is multiple, and the multiple card slots 111 are distributed along the length direction of the sealing strip body 1. Specifically, each card slot 111 corresponds to a support rod, and the spacing and size of the card slots 111 are determined by the position of the support rod. For example, the multiple card slots 111 can be evenly distributed along the length direction of the sealing strip body 1, such as the spacing is 150 mm, etc.

[0042] According to another aspect of the present disclosure, the dimension of the sealing strip body 1 in the width direction is 25 - 35 mm. Preferably, the thickness of the sealing strip body 1 is 30 mm.

[0043] According to another aspect of the present disclosure, the number of the sealing strip bodies 1 is multiple, and they are spliced in sequence along the length direction. For example, between two adjacent ceramic strip boards, the number of the sealing strip bodies 1 is three, and the three sealing strip bodies 1 are arranged in sequence along the length direction. Specifically, the three sealing strip bodies 1 are respectively denoted as A, B, and C; the total length of the combination of the three parts ABC is 9150 mm, and the total length of the ceramic strip suction area of the ceramic panel is 9150 mm. Installed according to the sorting in the figure, the position of the workpiece card slot is also 150 mm away from each support strip of the ceramic panel, and is fixedly installed through the cooperation of the card slot 111 and the support rod.

[0044] According to one aspect of the present disclosure, a paper machine is further provided, which includes a ceramic vacuum box and the sealing strip described above; a ceramic panel vacuum chamber one is formed inside the ceramic vacuum box.

[0045] A plurality of porcelain strip plates are provided in the suction area of the ceramic panel vacuum chamber one, and a strip-shaped inlet is formed between two adjacent porcelain strip plates; the sealing strip is arranged in part of the strip-shaped inlet. By arranging the sealing strip, the resistance of the suction area inlet can be increased, thereby reducing the vacuum degree of the ceramic panel vacuum chamber one, reducing the dehydration speed, avoiding a large number of white spots on the produced paper sheet, and being beneficial to improving the paper quality.

[0046] According to another aspect of the present disclosure, the number of the strip-shaped inlets is 16, and the number of the sealing strips is 4 - 8. Preferably, the number of the sealing strips is 6.

[0047] As described above, with reference to the drawings, the sealing strip for plugging the ceramic panel vacuum chamber one according to the embodiments of the present disclosure is described. By arranging the sealing strip in the suction area of the ceramic panel vacuum chamber one, the vacuum degree of the ceramic panel vacuum chamber one can be reduced, and the dehydration speed of the paper in the ceramic panel vacuum chamber one can be reduced.
