Description

Technical Field

[0001] The utility model relates to the technical field of papermaking machines, in particular to a pressing device for a papermaking machine. Background Art

[0002] A papermaking machine is a mechanical equipment used to produce paper. It is mainly composed of multiple parts, including but not limited to: pulp preparation system, forming system, dehydration system, drying system and post-processing system. The main working principle of the papermaking machine is to use mechanical force and chemical reaction to process pulp into paper, and through dehydration, drying and post-processing steps, make the paper reach the required quality and specifications.

[0003] In the existing paper machine pressing device, the paper is usually squeezed by applying pressure so that the moisture in the paper is discharged through the pressing roller. However, this pressing method also has some problems. First, due to the pressure exerted by the pressing roller on the paper, the moisture on the paper will flow to the unpressed area, resulting in an increase in the moisture content in the unpressed area, which requires an increase in the pressing workload. This situation not only increases the burden on the pressing equipment, but also affects the quality and production efficiency of the paper. Utility Model Content

[0004] The purpose of the utility model is to provide a paper machine pressing device to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a paper machine pressing device, comprising a support plate, a bearing frame is fixedly installed on the upper end of the support plate, a liquid storage bin is fixedly installed in the middle of the bearing frame, a pressing mechanism is arranged above the liquid storage bin, the pressing mechanism comprises a first liquid pressing roller body, a roller body groove, a second liquid pressing roller body, a roller body protrusion and a liquid blocking plate, a liquid blocking plate is fixedly installed on the bearing frame, a first liquid pressing roller body and a second liquid pressing roller body are arranged on the right side of the liquid blocking plate, a roller body groove is arranged in the middle of the first liquid pressing roller body, and a roller body protrusion is fixedly installed in the middle of the second liquid pressing roller body.

[0006] Optionally, the pressing mechanism also includes a first flattening roller, a second flattening roller, a first rotating rod, a second rotating rod, a first transmission belt, a first motor bracket, a first drive motor, a third rotating rod, a fourth rotating rod, a second transmission belt, a second motor bracket and a second drive motor. The first flattening roller is arranged on the right side of the first liquid pressing roller body, and the second flattening roller is arranged on the right side of the second liquid pressing roller body.

[0007] Optionally, a first rotating rod is fixedly installed at the middle of the first liquid pressing roller body, and a second rotating rod is fixedly installed at the middle of the second liquid pressing roller body.

[0008] Optionally, a first transmission belt is disposed on the outer sides of the first rotating rod and the second rotating rod, and a first motor bracket is disposed behind the first transmission belt.

[0009] Optionally, the first motor bracket is fixedly mounted on the bearing bracket, and a first driving motor is fixedly mounted on the first motor bracket.

[0010] Optionally, a third rotating rod is fixedly installed at the middle part of the first flattening roller rod, and a fourth rotating rod is fixedly installed at the middle part of the second flattening roller rod.

[0011] Optionally, a second transmission belt is disposed on the outer sides of the third rotating rod and the fourth rotating rod, a second motor bracket is disposed behind the second transmission belt, and a second driving motor is fixedly mounted on the second motor bracket.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] In the utility model, a pressing mechanism is provided. The pressing mechanism is provided with a specific roller structure, such as a roller groove on the first liquid pressing roller and a roller protrusion on the second liquid pressing roller. During the pressing process, the paper protrudes upward in the middle and tilts on both sides, which helps to guide the moisture in the paper to fall along the side slope of the paper to the liquid storage bin, thereby improving the dehydration efficiency; due to the effect of the liquid blocking plate, the moisture flowing to the left is effectively blocked, and the water body is prevented from flowing to the unpressed paper area, which not only reduces the burden on the unpressed area, but also helps to ensure the uniformity and consistency of the paper; in the traditional pressing method, due to the pressure exerted by the pressing roller on the paper, the moisture on the paper flows to the unpressed area, thereby increasing the pressing workload and increasing the burden on the equipment. The pressing mechanism effectively avoids this problem by guiding and blocking, thereby reducing the burden on the equipment, extending the service life of the equipment, and can effectively improve the dehydration efficiency of the paper and improve the quality of the paper, thus helping to improve the production efficiency of papermaking.
