Embodiment Construction

[0020] Below in conjunction with the accompanying drawings, a pressing device used in the papermaking industry of the present invention will be further described. like figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 As shown, a press device used in the paper industry includes a frame 1 on which an upper roll 2 and a lower roll 3 are fixed, and the upper roll 2 and the lower roll 3 are rotatably connected to the frame 1, and Both the upper roll 2 and the lower roll 3 are driven by the driving device to rotate, a pressing area 4 is formed between the upper roll 2 and the lower roll 3, and a felt for water absorption is also arranged between the upper roll 2 and the lower roll 3, and the paper blank After the pressing zone 4, the upper roll 2 and the lower roll 3 are used to extrude the water in the blank, and the water attached to the lower roll 3 is adsorbed by the felt; ;

[0021] see figure 1 , figure 2 , image 3 , the frame 1 is also fixed with a front wat...

Abstract

The invention relates to a pressing device for papermaking industry, and overcomes the disadvantages that the pressing device in the prior art is unreasonable in structure, and pressed water falls onto ground paper easily. According to the pressing device for the papermaking industry provided by the invention, a front water collecting groove and a rear water collecting groove are fixed to a machine frame; both the front water collecting groove and the rear water collecting groove are used for receiving accumulated water on an upper roller. The upper roller can rotate in a specific using process, so that the water accumulated on the upper roller is easily thrown away, and the water which is thrown away falls onto the ground paper easily to influence the quality of paper; the front water collecting groove and the rear water collecting groove converge the water on the upper roller in a groove and a water accumulating groove and discharge the water out, so that the water which is attached to the upper roller is effectively prevented from falling onto the ground paper; the water removal rate of the pressing device is improved, and the quality of the paper is improved.

Description

technical field [0001] The present invention relates to papermaking equipment, in particular to a pressing device used in the papermaking industry. Background technique [0002] Papermaking equipment is a device that makes pulp into paper. The pulp contains a lot of water. During the paper manufacturing process, the water in the pulp needs to be separated from the pulp by pressing to make the paper. [0003] In the prior art, the pressing device for separating water in pulp has an upper roll and a lower roll, the paper blank (pulp after preliminary forming) passes through the gap between the upper roll and the lower roll, and the upper roll cooperates with the lower roll. Water is pressed out to separate the water in the paper blank from the paper blank; however, the pressing device in the prior art does not have a device for recycling the squeezed water. After the water in the paper blank is pressed out, it is likely to fall off. It falls on the pressed paper blank, which ...
