Description

Technical Field

[0001] The utility model belongs to the technical field of papermaking, and specifically relates to a single-sided glossy paper sample drying device. Background Art

[0002] Single-sided glossy paper is a special type of paper. After the pulp is formed and pressed on the net, the wet paper directly enters the high-temperature large drying cylinder. Through high-temperature ironing and laminating and drying, the paper surface pasted on the cylinder is smooth, dense and high in gloss, which can meet some special usage requirements. Therefore, the special "mirror" property of single-sided glossy paper is mainly formed by its high-temperature laminating and drying conditions.

[0003] In order to avoid unnecessary losses caused by trial copying directly on the papermaking production line, it is best to create such drying conditions in the laboratory, conduct simulation tests to determine the optimal papermaking and production conditions for single-sided glossy paper, and then finally apply it on the paper machine.

[0004] However, currently, a separate drying plate is used to dry and prepare paper samples, and manual operation is required to flatten the wet paper web. The purpose of evenly flattening and tightly fitting the wet paper web mainly depends on operating experience, which is not convenient for quickly making a flat single-sided glossy paper sample. For this reason, we propose a single-sided glossy paper sample drying device. Utility Model Content

[0005] The utility model aims to provide a single-sided glossy paper sample drying device, which replaces the traditional manual smoothing operation of wet paper web by elastic extrusion so that the wet paper web is attached to a glossy plate, thereby facilitating the rapid production of a flat single-sided glossy paper sample.

[0006] The technical solutions adopted in this utility are as follows:

[0007] A single-sided smooth paper sample drying device comprises a heating box and a box cover hinged to the heating box, the upper surface of the heating box is sunken toward the middle and a smooth board is fixed to the lower surface of the sunken part, a canvas sheet is laid on the interior of the heating box above the smooth board, two sliders are slidably installed inside the box cover, a rubber roller is rotatably installed between the ends of the two sliders away from the box cover, a driving part for translating the rubber roller is arranged on the upper wall of the box cover, and the rubber roller presses the canvas sheet after the box cover and the heating box are closed, and the single-sided smooth paper sample made by drying with the smooth board can be subjected to conventional testing, especially for items such as tensile strength and bursting strength, which is very useful in quality control of finished paper and simulation of large-cylinder paper machine production test. The surface plays an important role. The wet paper web copied by the sheet copying device can be placed flat on the smooth plate at the sunken part of the heating box, and then a canvas piece can be laid on it, so that the canvas piece and the smooth plate can clamp the wet paper web from the upper and lower sides respectively, and then the box cover can be closed to drive the rubber roller to press the canvas piece, and the heating tube can be started to heat the wet paper web. The wet paper web is heated to evaporate water continuously and is dried. At the same time, the driving part is operated to reciprocate the rubber roller left and right at the sunken part, and the canvas piece is flattened by elastic extrusion, which saves the operation of smoothing the wet paper web with manual operation tools, so that the wet paper web can be flattened and attached on the smooth plate as soon as possible, so as to facilitate the rapid production of a flat single-sided smooth paper sample. Finally, the heating is stopped and the box cover is opened to obtain a single-sided smooth paper sample.

[0008] Two mutually parallel linear slide rails are fixed on the upper wall of the box cover, and the two linear slide rails are slidably connected with two sliders respectively. The two sliders and the rubber roller can be translated left and right along the two linear slide rails to limit and straighten the rubber roller to avoid tilting at the sunken place, so that its moving track covers the light plate.

[0009] The driving component includes an electric slide rail fixed on the upper wall of the box cover and parallel to the linear slide rail. The electric slide rail is slidably connected to a slider. A controller is fixed on the outside of the heating box. The controller is connected to the electric slide rail signal. A program is preset in the controller, and the operating options can control the heating or stopping of the heating tube, and start the electric slide rail along the two linear slide rails to push the two sliders and the rubber roller to move back and forth left and right on the light plate, or control the electric slide rail to stop.

[0010] Both sides of the sunken part of the heating box have rounded corners to leave space and allow margin for the translation of the rubber roller so that the lower surface of the rubber roller can reach both sides of the canvas piece.

[0011] A perspective window is embedded and installed at a position on the upper surface of the box cover facing the light board. The perspective window can be made of transparent glass material to facilitate vision through and observe whether the canvas piece has wrinkles.

[0012] An exhaust hole is provided on the back of the box cover, and the water vapor generated during the drying process can be discharged along the exhaust hole in a direction away from the staff, and can also be connected to a ventilation pipeline with a hose to prevent scalding of the staff.

[0013] The technical effects achieved by this utility model are:

[0014] The practical single-sided glossy paper sample drying device can conduct routine testing on the single-sided glossy paper sample made by drying the laminated glossy board, especially the tensile strength and bursting strength, which plays an important role in quality control of finished paper and simulation of large-cylinder paper machine production test. The wet paper web copied by the sheet copying device can be placed flat on the glossy board at the sunken part of the heating box, and then a canvas sheet can be spread on it, so that the canvas sheet and the glossy board can clamp the wet paper web from the upper and lower sides respectively, and then the box cover is closed to drive the rubber roller to press the canvas sheet, and the heating tube is started to heat the wet paper web. The wet paper web is heated to continuously evaporate water, and at the same time, the driving part is operated to reciprocate the rubber roller left and right at the sunken part, and the canvas sheet is flattened by elastic extrusion, so that the operation of smoothing the wet paper web with a manual operating tool is saved, so that the wet paper web can be flattened and laminated on the glossy board as soon as possible, so as to facilitate the rapid production of a flat single-sided glossy paper sample. Finally, the heating is stopped, the box cover is opened, and the single-sided glossy paper sample can be obtained. BRIEF DESCRIPTION OF THE DRAWINGS

The wet paper web made by the sheet copying device can be placed flat on the glossy board 3 at the sunken part of the heating box 1, and then covered with canvas sheet 4, so that the canvas sheet 4 and the glossy board 3 clamp the wet paper web from the upper and lower sides respectively, and then the box cover 2 is closed, the rubber roller 6 is driven to press the canvas sheet 4, and the heating tube is started to heat the wet paper web. The wet paper web is heated and the water is continuously evaporated. At the same time, the driving part is operated to reciprocate the rubber roller 6 left and right at the sunken part, and the canvas sheet 4 is flattened by elastic extrusion, which saves the operation of manually smoothing the wet paper web, so that the wet paper web can be flattened and attached on the glossy board 3 as soon as possible, so as to facilitate the rapid production of a flat single-sided glossy paper sample. Finally, the heating is stopped, and the box cover 2 is opened to obtain a single-sided glossy paper sample.

[0023] Among them, the surface of the canvas piece 4 is delicate and breathable, and its fiber is hydrophilic, which can increase the area of ​​​​the wet paper web for evaporating water. It is also low-cost and easy to obtain. A single-sided smooth paper sample can be placed in a tensile tester for testing. Even if the canvas piece 4 is damaged, the cost of scrapping the sample is relatively small.
