Description
Technical Field
[0001] This utility model relates to the field of papermaking technology, and in particular to a device for preparing Xuan paper. Background Technology
[0002] Currently, the production of Xuan paper still relies on traditional hand-made papermaking as the core process. Although this method can guarantee the unique quality of the paper, it also has problems such as low efficiency, high labor intensity, and high production costs, which restrict the large-scale development of the Xuan paper industry.
[0003] Handmade papermaking (paper scooping) requires artisans to repeatedly scoop paper from a pulp vat using a bamboo screen. The thickness and uniformity of each sheet depend entirely on experience, and a single person can only produce a few hundred sheets per day, making it time-consuming and labor-intensive. In addition, manual operation is easily affected by factors such as weather, water temperature, and raw material conditions, resulting in large batch-to-batch quality fluctuations and insufficient product stability.
[0004] In view of this, it is necessary to design a device for preparing Xuan paper to solve the above problems. Utility Model Content

[0020] Currently, most Xuan paper is made manually by making the paper and then drying it, a process that is time-consuming, labor-intensive, and inefficient.
[0021] Please see Figures 1 to 2 As shown, this utility model provides a Xuan paper-like paper preparation device 100, including an unwinding device 30, a pulping tank 1, a pulp tank 2, a first rolling mill, a spraying device, a second rolling mill, an oven 6, a winding device 9, and a conveyor belt 7 for conveying the pulp, arranged sequentially along the moving direction of the base fabric. The entire device is made of stainless steel. This device includes processes such as bark pulping, pulp web forming, base fabric lamination, functional finishing, oven drying, and unwinding and rewinding, realizing fully mechanized production from pulping and grinding to Xuan paper-like paper forming, reducing labor costs and greatly improving the production efficiency of Xuan paper.
[0022] In this embodiment, the pulping tank 1 is an open cuboid structure, with its four corners supported by legs. Pulping blades 11 are installed at the bottom of the pulping tank 1. The pulping blades 11 are driven by a motor and are used to break the bark of the sandalwood into pulp.
[0023] The cross-section of the slurry tank 2 is shaped like an inverted right-angled trapezoid, with the mixing tank 1 positioned near the right-angled side. A ball valve 12 is installed between the mixing tank 1 and the slurry tank 2 to control their connection. Opening the ball valve 12 allows the mixed slurry to be poured into the slurry tank 2. A stirring device 21 for mixing the slurry is installed at the top of the slurry tank 2; this stirring device 21 is driven by a motor.
[0024] In this embodiment, the conveyor belt 7 includes an inclined section 71 and a horizontal section 72. The inclined section 71 extends in a direction parallel to the inclined side of the slurry tank 2. One end of the inclined section 71 is inside the slurry tank 2, and the other end extends to the outside of the slurry tank 2 and connects with the horizontal section 72. After the conveyor belt 7 is turned on, the slurry in the slurry tank 2 will adhere to the conveyor belt 7.
[0025] Specifically, the conveyor belt 7 is made of 50-mesh fine mesh and is driven by four conveyor wheels 8. The fine mesh has needles on both sides to fix the base fabric 10.
[0026] The first rolling mill has a first pressure roller 31 and a first drive roller 32 arranged vertically opposite each other, and the second rolling mill has a second pressure roller 51 and a second drive roller 52 arranged vertically opposite each other. The first pressure roller 31 and the second pressure roller 51 are pressure rollers wrapped with synthetic material, and the first drive roller 32 and the second drive roller 52 are drive rollers covered with stainless steel material.
[0027] The horizontal section 72 of the conveyor belt 7 passes sequentially between the first pressure roller 31 and the first drive roller 32, and between the second pressure roller 51 and the second drive roller 52.
[0028] The pressure rollers are raised or lowered by a pneumatic control device to press the base fabric 10 and the bark pulp together. Waste liquid collection tanks 33 and 53 are respectively installed below the first rolling mill and the second rolling mill.
[0029] The spraying device is located between the first and second rolling mill cars. The spraying device includes a storage tank 42 and spray nozzles 41. The storage tank 42 is used to store functional additives. The spray nozzles are fan-shaped, with a width sufficient to cover the conveyor belt 7.
[0030] Oven 6 is a forced-air oven, heated by heating wires to dry the composite of sandalwood bark and base fabric 10.
[0031] The unwinding device 30 is used to place the base fabric 10.
[0032] The winding device 9 is used to wind up the dried fabric sample.
[0033] The working principle of the Xuan paper preparation device of this utility model is explained below:
[0034] 1. Pour a certain amount of sandalwood bark and water into pulping tank 1, soak for a period of time, then turn on the motor to pulp the sandalwood bark into sandalwood pulp;
[0035] 2. Place the base fabric 10 on the unwinding device 30. After the base fabric 10 passes through the guide roller 13, fix it to the needles on both sides of the conveyor belt 7.
[0036] 3. Open the ball valve 12 connecting the pulping tank 1 and the pulp tank 2, and inject the sandalwood pulp into the pulp tank 2. When the pulp covers the stirring blades, turn on the stirring device in the pulp tank 2 to make the pulp distribution more uniform.
[0037] 4. Turn on the machine equipment; the conveyor belt 7, the first rolling mill, the second rolling mill, the drying oven 6, and the winding device 9 start simultaneously.
[0038] 5. As the conveyor belt 7 slowly rotates, the slurry in the slurry tank 2 will adhere to the conveyor belt 7 and be transported backward with the conveyor belt 7; at the same time, the base fabric 10 fixed on the conveyor belt 7 will also be transported backward with the conveyor belt 7. When the slurry is transported to the base fabric 10, it will adhere to the base fabric 10.
[0039] 6. The first rolling mill applies a certain pressure to the bonded sandalwood pulp and base fabric 10 to further bond them together and squeeze out some water to facilitate drying. When the bonded sandalwood pulp and base fabric 10 pass through the spraying device, the spraying device can spray the required functional additives onto the base fabric 10 through the nozzle 41. The additives on the base fabric 10 will penetrate into the pulp, so that both the base fabric 10 and the pulp are wetted by the additives.
[0040] 7. Control the liquid content of the additives on the base fabric by using the second rolling mill; adjust the pressure of the rolling mill on the base fabric by controlling the pressure between the two rolling mills to achieve the required liquid content of the additives on the base fabric.
[0041] 8. The sandalwood pulp and base fabric 10 bonded together on the conveyor belt 7 enter the forced-air drying oven 6 to dry them;
[0042] 9. The dried Xuan paper is wound up using the winding device 9.
[0043] Through the above process, the equipment for preparing this type of Xuan paper can realize the entire process from pulping of sandalwood bark, pulp forming, base fabric lamination, functional finishing, oven drying, unwinding and rewinding, etc., achieving mechanized production from pulping and grinding to the forming of Xuan paper, reducing labor costs and greatly improving production efficiency.
[0044] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model.
