Technical Field

[0001] The utility model belongs to the technical field of paper dehydration, and in particular relates to a paper machine composite pressing device for low-basis corrugated paper. Background Art

[0002] Opportunities and challenges coexist, and market competition within the industry is intensifying. Papermaking companies need to increase investment in innovation and research and development, and rely on technological progress to reduce pollution and consumption, improve quality and efficiency, and achieve green and low-carbon development.

[0003] At present, for the production of low-quantity corrugated paper and boxboard using waste paper raw materials, due to the degradation of plant fiber recycling, the bonding force between fibers is poor, the strength of paper sheets is low, and the wet paper sheets are easily broken during the transfer process, resulting in reduced paper machine production efficiency and high energy consumption costs. The existing paper machine composite pressing device for producing corrugated core paper usually includes a plurality of independent upper and lower pressing rollers, and the moisture in the paper is squeezed out through multiple composite pressing processes. However, during the extrusion and dehydration process, the spacing between the upper and lower pressing rollers is adjusted, and the current adjustment method mainly relies on manual operation. The accuracy of this adjustment method is low, which has an adverse effect on the dehydration effect.

[0004] Therefore, based on the above problems, we designed a paper machine composite pressing device for low-weight corrugated paper. Utility Model Content

[0005] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model proposes a paper machine composite pressing device for low-weight corrugated paper, which solves the technical problem that the existing paper machine composite pressing device adjusts the spacing between the upper and lower pressing rollers during the extrusion and dehydration process, and the current adjustment method mainly relies on manual operation, which has low accuracy and has an adverse effect on the dehydration effect.

[0006] To achieve the above-mentioned object, according to an embodiment of the first aspect of the utility model, a paper machine composite pressing device for low-basis-weight corrugated paper is provided, comprising a pressing machine, wherein the pressing machine comprises a base and a plurality of paper feeding rollers arranged in the base;

[0007] Also includes:

[0008] The upper paper pressing roller and the lower paper pressing roller are respectively arranged in the ports of the base, and the upper paper pressing roller is arranged above the lower paper pressing roller;

[0009] The adjustment structure includes a pair of micro-telescopic cylinders vertically arranged on the top surface of the base and a pair of sliding seats on the inner wall surface. A pair of sliding seats are rotatably arranged on both sides of the upper paper pressing roller. The rod body of each micro-telescopic cylinder passes through the base and is connected to the top surface of the sliding seat. The outer wall surface of the base is provided with a scale, and the side surface of the sliding seat is provided with an indicating rod in contact with the scale.

[0010] A further improvement is that a slide groove is provided through the inner wall surface of the base, and a limiting groove is provided on both sides of the slide groove on the outer wall surface of the base. The middle part of each sliding seat is arranged in the slide groove, and guide blocks are provided on both sides of the inner wall surface of each sliding seat, and each guide block is slidably arranged in the limiting groove.

[0011] A further improvement is that a water collecting cover is additionally arranged inside the base and below the lower paper pressing roller, and a water outlet is arranged on one side of the bottom surface of the water collecting cover.

[0012] A further improvement is that the water outlet surface of the water collecting cover is inclined and inclined towards the water outlet.

[0013] A further improvement is that the inner wall of the base is connected to a water collecting tank, and the water inlet of the water collecting tank is connected to the water outlet of the water collecting cover.

[0014] A further improvement is that the press also includes several reducers, and the main shafts of the reducers are connected to the ends of the paper feeding roller and the lower paper pressing roller.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] (1) This novel device is designed with an automatic adjustment structure. When the spacing needs to be adjusted, a pair of micro-telescopic cylinders on both sides of the base are simultaneously activated to drive a pair of sliding seats on the inner wall surface to move up and down. During the process of the sliding seats moving up and down, they will synchronously drive the indicator rod on one side to slide on the scale on the side of the base, thereby achieving highly accurate control, that is, accurately controlling the spacing between the upper paper pressing roller and the lower paper pressing roller to meet the needs of extrusion and dehydration. Similarly, other presses can also be adjusted in the same way.

[0017] (2) The new model is also equipped with a water collection device. Each time the upper and lower paper pressing rollers squeeze out the water from the paper, the water will flow along the lower paper pressing roller to the water collection cover, then flow along the inclined surface of the water collection cover to the water outlet, and finally flow into the collection water tank for collection. This design effectively prevents water from remaining in the press, thereby reducing the cleaning burden of subsequent personnel. BRIEF DESCRIPTION OF THE DRAWINGS

In the process of the sliding seat 22 rising and falling, they will synchronously drive the indicator rod 25 on one side to slide on the scale 24 on the side of the base 13, so as to achieve high precision control, that is, accurately control the distance between the upper paper pressing roller 3 and the lower paper pressing roller 4;

[0027] Specifically, as a preferred embodiment, the inner wall surface of the base 13 is provided with a slide groove 23, and the outer wall surface of the base 13 is provided with limiting grooves 231 on both sides of the slide groove 23. The middle part of each sliding seat 22 is arranged in the slide groove 23, and the inner wall surface of each sliding seat 22 is provided with guide blocks 232 on both sides. Each guide block 232 is respectively slidably arranged in the limiting groove 231. The guide blocks 232 and the limiting groove 231 are used to limit the sliding of the sliding seat 22 to ensure the sliding stability of the sliding seat 22.

[0028] like Figure 2 As shown, in the present embodiment, a water collecting cover 5 is additionally provided on the inner side of the base 13 and below the lower paper pressing roller 4, a water outlet 51 is provided on one side of the bottom surface of the water collecting cover 5, the water outlet surface of the water collecting cover 5 is inclined and inclined toward the water outlet 51, a water collecting tank 52 is connected to the inner wall of the base 13, a water inlet of the water collecting tank 52 is connected to the water outlet 51 of the water collecting cover 5, this design effectively avoids water from remaining in the press 1, thereby reducing the cleaning burden of subsequent personnel.

Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical method of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the utility model.
