Description

Technical Field

[0001] This utility model relates to the field of papermaking technology, specifically a forming device for improving the fiber distribution of kraft paper pulp. Background Technology

[0002] Kraft paper is made from long-fiber wood pulp through pulping, forming, and drying processes. In the wet forming stage, the pulp fibers need to be subjected to high-frequency transverse shaking on the breast roller to break the tendency of fiber flocculation and promote their uniform dispersion. This process can optimize the fiber interlacing structure, reduce the difference in longitudinal and transverse strength of the paper, and improve the uniformity of dehydration, avoiding paper defects such as cloud patterns. It is a key technical link to ensure the high tensile strength and thickness consistency of kraft paper.

[0003] A search revealed a novel paper machine breast roll vibrating device disclosed in Chinese Patent Publication No. CN207498727U, which includes a support plate, a placement platform welded to the top of the front side of the support plate, a motor mounted on the front side of the placement platform, a first pulley fixedly connected to the output end of the motor via a coupling, and a base fixedly connected to the front side of the support plate.

[0004] While the above solution can buffer the connecting rod, there is still room for optimization in practical applications. Since the connecting rod is currently confined in the chute, it is impossible to adjust the amplitude of the connecting rod according to different types of breast rolls and pulp characteristics. This results in limited fiber orientation control during papermaking, which in turn affects the strength and smoothness of the paper. To address this issue, we provide a forming device that improves the fiber distribution of kraft paper pulp. Utility Model Content

[0022] 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.

[0023] like Figure 1 As shown, this utility model provides a technical solution for a molding device that improves the fiber distribution of kraft paper pulp, including a supporting base plate 1. A power supply is installed on the outer surface of the supporting base plate 1, which can supply power to the electrical equipment in this application.

[0024] like Figure 2 , Figure 3 and Figure 4As shown, an adjustment mechanism 2 is provided above the supporting base plate 1. The adjustment mechanism 2 includes an active disk 201. A limiting groove 202 is fixedly connected to the outer surface of the active disk 201. An adjustment screw 203 is rotatably connected to the inner wall of the limiting groove 202. A threaded slider 204 is threadedly connected to the outer surface of the adjustment screw 203. The outer surface of the threaded slider 204 is slidably connected to the limiting groove 202. By driving the adjustment screw 203 to rotate, the threaded slider 204 can be driven to slide synchronously in the inner wall of the limiting groove 202, thereby effectively adjusting the amplitude of the rocking rod 210.

[0025] An adjusting motor 205 is fixedly connected to the outer surface of the limiting slide 202. The output end of the adjusting motor 205 is fixedly connected to the adjusting screw 203. The outer surface of the device housing 301 is equipped with a control button for the adjusting motor 205. The adjusting motor 205 can be started and stopped by the control button. Starting the adjusting motor 205 can effectively drive the adjusting screw 203 to rotate.

[0026] A driven rod 206 is rotatably connected to the outer surface of the threaded slider 204. The end of the driven rod 206 away from the threaded slider 204 is rotatably connected to a limit plate 207. By driving the drive disc 201 to rotate, the driven rod 206 can be driven to swing simultaneously.

[0027] The inner wall of the limiting plate 207 is slidably connected to a limiting slide rod 208. Both ends of the limiting slide rod 208 are fixedly connected to a support frame 209. The outer surface of the support frame 209 is fixedly connected to the outer shell 301 of the device. The outer surface of the limiting plate 207 is fixedly connected to a rocking rod 210. The outer surface of the rocking rod 210 is slidably connected to the outer shell 301. Through the setting of the limiting slide rod 208, the limiting plate 207 is effectively limited, making the limiting plate 207 more stable during reciprocating motion.

[0028] A buffer spring 211 is sleeved on the outer surface of the limiting slide bar 208. One end of the buffer spring 211 is fixedly connected to the support frame 209, and the end of the buffer spring 211 away from the support frame 209 is fixedly connected to the buffer contact plate 212. Through the synergistic effect of the buffer spring 211 and the buffer contact plate 212, the reciprocating motion of the limiting plate 207 can be buffered, effectively improving the safety of the driven rod 206 when swinging.

[0029] like Figure 1 and Figure 3As shown, a compatibility mechanism 3 is provided above the support base plate 1. The compatibility mechanism 3 includes a device housing 301. The outer surface of the device housing 301 is slidably connected to the support base plate 1. The inner wall of the device housing 301 is rotatably connected to the drive disk 201. A drive motor is fixedly installed inside the device housing 301. The output end of the drive motor is fixedly connected to the center of the surface of the drive disk 201, so that the drive disk 201 can be effectively driven to rotate by starting the drive motor.

[0030] The regulating motor 205 and the drive motor mentioned in this application are common electrical devices in the prior art. This application will not elaborate on their models and internal structures. They can also be replaced by other power sources.

[0031] The inner wall of the support base plate 1 is rotatably connected to an adjusting screw 302. The outer surface of the adjusting screw 302 is threadedly connected to the outer shell 301 of the device. By driving the adjusting screw 302 to rotate, and in conjunction with the setting of the limiting slide rod 303, the device shell 301 can be effectively driven to move vertically according to the meshing force.

[0032] The inner wall of the device housing 301 is slidably connected to a limiting slide rod 303. One end of the limiting slide rod 303 is fixedly connected to the bearing base plate 1. The limiting slide rod 303 effectively limits the device housing 301, making the device housing 301 more stable during vertical adjustment.

[0033] The structural diagrams of the components shown in the attached figures are exemplary. The specific implementation should be adapted and optimized by considering the functional requirements, assembly conditions and process limitations in the actual application scenario, and adjusting the structural parameters, size specifications and connection methods accordingly.

[0034] Working principle: First, the rotation of the second driving adjusting screw 302, combined with the limiting slide bar 303, effectively adjusts the height of the vibrating rod 210 inside the device housing 301, allowing the vibrating rod 210 to be used with different models of papermaking machines, significantly improving the compatibility of this device. Second, by starting the drive motor inside the device housing 301, the active disk 201 is driven to rotate. The rotation of the active disk 201 drives the threaded slider 204 on the inner wall of the limiting slide groove 202 to rotate synchronously. The rotation of the threaded slider 204 drives the driven rod 206 to swing. The swing of the driven rod 206 causes the limiting plate 207 to slide back and forth on the surface of the first limiting slide bar 208. The movement of the first limiting slide bar 208 drives the vibrating rod 210 to move synchronously. The device effectively provides continuous vibration to the breast roll in the paper machine. During the operation of the vibrating rod 210, the regulating motor 205 is activated to drive the regulating screw 203 to rotate. The rotation of the regulating screw 203 causes the threaded slider 204 to slide in the inner wall of the limiting groove 202. The movement of the threaded slider 204 effectively changes the swing amplitude of the driven rod 206. The change in the swing amplitude of the driven rod 206 will synchronously cause the movement amplitude of the vibrating rod 210 on the surface of the limiting plate 207 to change. Thus, this device can make targeted adjustments to the amplitude of the vibrating rod 210 according to different types of breast rolls and pulp characteristics. Through this optimization, the fiber orientation can be flexibly controlled during the papermaking process, which greatly improves the strength and surface smoothness of the paper.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
