Description

Technical Field

[0001] This utility model relates to the field of specialty paper preparation technology, specifically to a specialty paper preparation device. Background Technology

[0002] Specialty papers are usually made using special pulp. After the pulp is prepared, it needs to be shaped using a paper machine. In order to speed up the drying of the pulp, it is usually necessary to squeeze out the water, reduce the water content in the pulp, and shape the pulp.

[0003] Existing squeeze drainage methods mostly rely on a single squeeze cylinder. However, excessive single-squeeze pressure can easily cause pulp clumping, resulting in poor paper smoothness. Therefore, we propose a special paper preparation device to address the aforementioned problems. Utility Model Content

[0004] The purpose of this invention is to provide a special paper preparation device to solve the problem mentioned in the background art that most current extrusion drainage methods use a single extrusion cylinder for drainage. Due to the excessive pressure of a single extrusion, the pulp is prone to clumping, resulting in poor paper flatness.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a special paper preparation device, comprising: The frame has an upper conveyor belt and a lower conveyor belt inside, with the upper conveyor belt located above the lower conveyor belt. Both the upper and lower conveyor belts have drive rollers on their right sides, and motors are connected to the rear ends of the drive rollers. The motors are fixedly connected to the frame. Support rollers are provided at the bottom of the upper conveyor belt and on the left side of the lower conveyor belt. An upper water plate is provided on the lower right side of the upper conveyor belt, and a lower water plate is provided on the lower side of the lower conveyor belt. The upper and lower water plates are connected by a water guide pipe. An adjusting roller is provided at the left end of the upper conveyor belt, and a spring is connected to the outer end of the adjusting roller. A first extrusion roller is disposed below the middle of the upper conveyor belt, and a second extrusion roller is disposed to the right of the first extrusion roller.

[0006] Preferably, both the upper and lower conveyor belts are filter conveyor belts, and the left and right ends of the upper conveyor belt are inclined.

[0007] Preferably, both the first and second extrusion rollers are provided with adjustment mechanisms, and the height of the second extrusion roller is lower than that of the first extrusion roller.

[0008] Preferably, the adjustment mechanism includes an adjustment rod, an adjustment sleeve, and a connecting rod, wherein the adjustment sleeve is provided on the outer side of the adjustment rod, and the connecting rod is connected to the lower part of the adjustment sleeve.

[0009] Preferably, the adjusting rod has opposite threaded structures at its front and rear, and adjusting sleeves are symmetrically arranged at its front and rear.

[0010] Preferably, the upper and lower ends of the connecting rod are rotatably connected to the ends of the adjusting sleeve and the second extrusion roller, respectively, and the adjusting rod forms a transmission mechanism with the second extrusion roller through the adjusting sleeve and the connecting rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the special paper preparation equipment can squeeze the pulp multiple times, which facilitates the uniform spreading of the pulp, thereby ensuring the flatness of the pulp, and avoids water droplets remaining on the upper conveyor belt falling onto the dewatered pulp, which facilitates the uniform humidity of the dewatered pulp and facilitates the subsequent drying of the pulp. 1. An upper conveyor belt and a water plate are installed. The left and right ends of the upper conveyor belt are inclined to facilitate the conveying and squeezing of the pulp. The water plate is located on the lower right side of the upper conveyor belt to facilitate the collection of residual water on the right side of the upper conveyor belt, so as to ensure the uniform moisture of the pulp after dewatering and facilitate the subsequent drying of the pulp. 2. A first extrusion roller and a second extrusion roller are provided. The first extrusion roller and the second extrusion roller can perform secondary extrusion on the pulp, which facilitates the uniform spreading of the pulp and ensures the flatness of the pulp. When the first extrusion roller and the second extrusion roller are adjusted, the tension of the upper conveyor belt can be adjusted by adjusting the roller, which facilitates the use of the upper conveyor belt. 3. An adjustment mechanism is provided, which includes an adjustment rod, an adjustment sleeve, and a connecting rod. By rotating the adjustment rod, the adjustment sleeve can be moved, thereby adjusting the position and height of the first extrusion roller through the connecting rod, thus adjusting the pulp pressure and facilitating the extrusion and molding of the pulp.

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-4 This utility model provides a technical solution: a special paper preparation equipment, including: a frame 1, an upper conveyor belt 2, a lower conveyor belt 3, a support roller 4, a first extrusion roller 5, a second extrusion roller 6, an adjusting roller 7, a drive roller 8, a motor 9, an upper water plate 10, a lower water plate 11, a water guide pipe 12, a spring 13, and an adjusting mechanism 14. The frame 1 has an upper conveyor belt 2 and a lower conveyor belt 3 inside, with the upper conveyor belt 2 located above the lower conveyor belt 3. Both the upper conveyor belt 2 and the lower conveyor belt 3 have drive rollers 8 inside on their right sides, and the rear end of the drive rollers 8 is connected to a motor 9, which is fixedly connected to the frame 1. The bottom of the upper conveyor belt 2 and the left side of the lower conveyor belt 3 are both equipped with support rollers 4. The lower right side of the upper conveyor belt 2 is equipped with an upper water plate 10, and the lower side of the lower conveyor belt 3 is equipped with a lower water plate 11. The upper water plate 10 and the lower water plate 11 are connected by a water guide pipe 12. The left end of the upper conveyor belt 2 is equipped with an adjusting roller 7, and the outer end of the adjusting roller 7 is connected to a spring 13. The first extrusion roller 5 is located below the middle of the upper conveyor belt 2, and a second extrusion roller 6 is located on the right side of the first extrusion roller 5.

[0016] like Figure 1 , Figure 2 and Figure 4 Both the upper and lower conveyor belts 2 and 3 are filter conveyor belts, and the left and right ends of the upper conveyor belt 2 are inclined to facilitate the conveying of pulp. The first squeeze roller 5 and the second squeeze roller 6 are both equipped with adjustment mechanisms 14, and the height of the second squeeze roller 6 is lower than that of the first squeeze roller 5 to facilitate multiple squeezes of the pulp.

[0017] like Figure 2 and Figure 3The adjustment mechanism 14 includes an adjustment rod 1401, an adjustment sleeve 1402, and a connecting rod 1403. The adjustment sleeve 1402 is provided on the outer side of the adjustment rod 1401, and the connecting rod 1403 is connected to the lower part of the adjustment sleeve 1402 to facilitate the movement of the second extrusion roller 6. The adjustment rod 1401 has opposite threaded structures at the front and rear, and the adjustment sleeve 1402 is symmetrically arranged at the front and rear of the adjustment rod 1401 for easy operation. The upper and lower ends of the connecting rod 1403 are rotatably connected to the ends of the adjustment sleeve 1402 and the second extrusion roller 6, respectively. The adjustment rod 1401 and the second extrusion roller 6 form a transmission mechanism through the adjustment sleeve 1402 and the connecting rod 1403 to provide power for the lifting and lowering of the second extrusion roller 6.

[0018] Working principle: When using this special paper preparation equipment, such as Figure 1 As shown, by starting the motors 9 on the upper conveyor belt 2 and the lower conveyor belt 3, the upper conveyor belt 2 and the lower conveyor belt 3 are rotated, causing the pulp to be conveyed through the lower conveyor belt 3, as shown. Figure 4 As shown, when the pulp moves to the first extrusion roller 5, it is extruded once by the first extrusion roller 5. Then, when it is conveyed to the second extrusion roller 6, it is extruded a second time, thereby forming and dewatering the pulp. The squeezed water falls into the lower water plate 11 for collection, while the water remaining on the right side of the upper conveyor belt 2 falls into the upper water plate 10 for collection and flows into the upper water plate 10 through the water guide pipe 12. like Figure 3 As shown, by rotating the adjusting rod 1401, the adjusting rod 1401 drives the adjusting sleeve 1402 to move. Since the upper and lower ends of the connecting rod 1403 are rotatably connected to the adjusting sleeve 1402 and the end of the second extrusion roller 6 respectively, the second extrusion roller 6 is raised and lowered on the frame 1, thereby adjusting the position height of the second extrusion roller 6 to facilitate control of the extrusion intensity. The position height adjustment of the first extrusion roller 5 is the same as that of the second extrusion roller 6. In order to balance the tension of the upper conveyor belt 2, when the upper conveyor belt 2 is under force, the adjusting roller 7 adjusts the tension of the upper conveyor belt 2 through the extrusion spring 13. This is the entire working process of the special paper preparation equipment. The contents not described in detail in this specification belong to the prior art known to those skilled in the art.
