Description

Technical Field

[0001] This invention relates to the field of yarn tube paper technology, and more specifically, to a pulp mixing apparatus for yarn tube paper production. Background Technology

[0002] Yarn tube paper is an industrial paper specifically used in the textile and chemical fiber industries for winding yarns, filaments, and other materials into paper cores. It features high strength, high stiffness, and good moisture resistance, ensuring shape stability and resistance to deformation during high-speed winding and unwinding. Yarn tube paper is typically made from multiple layers of kraft pulp or recycled pulp through a special pressing process, resulting in a smooth surface and neat edges. Different thicknesses and sizes can be customized to meet specific needs, making it an indispensable basic material in textile production.

[0003] Pulp is a fibrous material obtained from plant fibers through mechanical or chemical processing to remove impurities. It is an intermediate product in the production of paper tubes. Pulp preparation requires prolonged stirring to prevent fiber sedimentation and maintain a uniform and stable pulp. Simultaneously, it promotes the complete dissociation of fiber bundles into individual fibers, and under mechanical force, the fibers absorb water, swell, and flocculentize to enhance their binding strength. Furthermore, it ensures that various additives are thoroughly and evenly mixed with the fibers and inhibits fiber flocculation, thereby guaranteeing the strength, uniformity, and quality stability of the final paper.

[0004] Paper pulp is a fibrous suspension containing a large amount of plant fibers, exhibiting a certain degree of viscosity and interweaving. During the mixing process, under the influence of centrifugal force, fiber and filler particles in the pulp are thrown towards the inner wall of the container. Simultaneously, if the pulp concentration is high or its fluidity is poor, the pulp flow rate near the wall is slow, easily forming a stagnant layer that gradually accumulates. This adhesion phenomenon not only wastes pulp and increases cleaning difficulty, but long-term accumulation can also affect mixing efficiency and pulp uniformity. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a pulp mixing device for yarn tube paper production.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a pulp mixing device for yarn tube paper production, comprising a tank, a rotating assembly, and a lifting assembly; The upper end of the tank is connected to a feed pipe, and the lower end of the tank is connected to a discharge pipe. A valve is installed on the discharge pipe. A ring rail is fixedly connected to the side wall of the feed pipe. Multiple sliders are slidably connected to the ring rail. The multiple sliders are all fixedly connected to a sleeve. An upper ring plate is fixedly connected to the sleeve. Multiple guide rods are slidably connected to the upper ring plate. The lower ends of the multiple guide rods are all fixedly connected to a movable ring plate. A spring is sleeved on each of the multiple guide rods. The upper end of each spring is fixedly connected to the upper ring plate, and the lower end of each spring is fixedly connected to the movable ring plate. A horizontal arm is fixedly connected to the upper end of each of the multiple guide rods. A vertical rod is fixedly connected to each of the multiple horizontal arms. The multiple vertical rods are all fixedly connected to a stirring ring plate. The stirring ring plate is located inside the tank. The rotating assembly is mounted on the tank body and is used to drive the sleeve to rotate. The lifting assembly is installed on the tank body and is used to drive the movable ring plate to rise and fall.

[0007] A further technical solution of this application: The rotating assembly includes a lower ring plate, an external gear ring, a gear, and a motor. The lower ring plate is fixedly connected to the sleeve. An external gear ring is fixedly connected to the lower ring plate. A gear is meshed on the external gear ring. The gear is fixedly connected to the output shaft of the motor. The motor is mounted on the tank.

[0008] A further technical solution of this application: The lifting assembly includes a first electric cylinder and a push-pull frame. The first electric cylinder is installed on the tank body, and the push-pull frame is fixedly connected to the piston rod of the first electric cylinder. Two horizontal plates are integrally formed on the push-pull frame, and the two horizontal plates are respectively located on the upper and lower sides of the movable ring plate.

[0009] A further technical solution of this application: multiple rollers are rotatably connected to the end faces of the two horizontal plates that are close to each other.

[0010] A further technical solution of this application: a vertical shaft is fixedly connected to the stirring ring plate, and a spiral blade is fixedly connected to the vertical shaft.

[0011] A further technical solution of this application: supports are fixedly connected to both sides of the tank, and horizontal shafts are fixedly connected to the two supports respectively. Both horizontal shafts are rotatably connected to the base. A second electric cylinder is hinged to the base, and the piston rod of the second electric cylinder is hinged to the side wall of the tank.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. The rotating assembly drives the sleeve to rotate, and the sleeve drives multiple guide rods to rotate through the upper ring plate on it. The multiple guide rods drive the stirring ring plate to rotate through the horizontal arm and vertical rod, so that the stirring ring plate can stir the pulp inside the tank. 2. During the process of discharging the pulp from the tank, the upper half of the agitator ring plate comes into contact with the inner wall of the upper half of the tank. The agitator ring plate is slowly rotated by the rotating component, which scrapes off the pulp adhering to the inner wall of the upper half of the tank. Then, the lower half of the agitator ring plate comes into contact with the inner wall of the lower half of the tank, which scrapes off the pulp adhering to the inner wall of the lower half of the tank. This cleans the pulp adhering to the inner wall of the tank and prevents the pulp adhering to the inner wall from affecting the mixing efficiency and pulp uniformity. 3. The base supports the tank body through the support and the horizontal axis, and the second electric cylinder can drive the tank body to rotate around the horizontal axis by a certain angle. Changing the angle of the tank body during the mixing process can effectively improve the mixing efficiency and the uniformity of the slurry.

The upper end of the tank body 1 is connected to a feed pipe 2, and the lower end of the tank body 1 is connected to a discharge pipe 3. A valve is installed on the discharge pipe 3. Figure 2 and Figure 3 Raw materials are injected into the tank 1 through the feed pipe 2, and the stirred pulp is discharged through the discharge pipe 3. The opening and closing of the discharge pipe 3 is controlled by a valve on the discharge pipe 3.

The lower ends of the multiple guide rods 8 are fixedly connected to the movable ring plate 9. Springs 10 are respectively sleeved on the multiple guide rods 8. The upper end of each spring 10 is fixedly connected to the upper ring plate 7, and the lower end of each spring 10 is fixedly connected to the movable ring plate 9.

The multiple vertical rods 12 are fixedly connected to the stirring ring plate 13, which is located inside the tank body 1. like Figure 3 and Figure 4 The movable ring plate 9 is suspended by multiple springs 10, the movable ring plate 9 supports multiple guide rods 8, the multiple guide rods 8 support the vertical rods 12 by the horizontal arms 11, and the multiple vertical rods 12 support the stirring ring plate 13, so that the stirring ring plate 13 is located inside the tank 1 and does not contact the inner wall of the tank 1. The rotating assembly is mounted on the tank body 1, and the rotating assembly is used to drive the sleeve 6 to rotate. like Figure 3 and Figure 4 The rotating assembly drives the sleeve 6 to rotate, and the sleeve 6 drives multiple guide rods 8 to rotate through the upper ring plate 7 on it. The multiple guide rods 8 drive the stirring ring plate 13 to rotate through the horizontal arm 11 and the vertical rod 12, so that the stirring ring plate 13 can stir the pulp inside the tank 1. The lifting assembly is installed on the tank body 1, and the lifting assembly is used to drive the movable ring plate 9 to rise and fall. like Figure 3 and Figure 4 During the process of discharging the pulp inside the tank 1, the lifting assembly can first drive the movable ring plate 9 to rise, the movable ring plate 9 can drive multiple guide rods 8 to rise, and the multiple guide rods 8 can drive the stirring ring plate 13 to rise through the horizontal arm 11 and the vertical rod 12, so that the upper half of the stirring ring plate 13 contacts the inner wall of the upper half of the tank 1, and the rotating assembly can drive the stirring ring plate 13 to rotate slowly, so that the stirring ring plate 13 can scrape off the pulp attached to the inner wall of the upper half of the tank 1. Subsequently, the lifting assembly drives the movable ring plate 9 to descend, causing the lower half of the stirring ring plate 13 to come into contact with the inner wall of the lower half of the tank 1. The stirring ring plate 13 can then scrape off the pulp adhering to the inner wall of the lower half of the tank 1, thereby cleaning the pulp adhering to the inner wall of the tank 1 and preventing the pulp adhering to the inner wall from affecting the stirring efficiency and pulp uniformity.

[0020] In a preferred embodiment of this application, the rotating assembly includes a lower ring plate 14, an external gear ring 15, a gear 16, and a motor 17.

[0022] In a preferred embodiment of this application, multiple rollers 21 are rotatably connected to the end faces of the two horizontal plates 20 that are close to each other; like Figure 5 The horizontal plate 20 abuts against the movable ring plate 9 through multiple rollers 21 on it, so as not to affect the rotation of the movable ring plate 9.

Changing the angle of the tank 1 during the stirring process can effectively improve the stirring efficiency and the uniformity of the slurry.

[0025] In practical applications, other linear drive components can be used to replace the electric cylinder, and this application does not limit this.

[0026] Working principle: During the process of discharging pulp from the tank 1, the lifting component can first drive the movable ring plate 9 to rise, the movable ring plate 9 can drive multiple guide rods 8 to rise, and the multiple guide rods 8 can drive the stirring ring plate 13 to rise through the horizontal arm 11 and the vertical rod 12, so that the upper half of the stirring ring plate 13 contacts the inner wall of the upper half of the tank 1, and the rotating component can drive the stirring ring plate 13 to rotate slowly, so that the stirring ring plate 13 can scrape off the pulp attached to the inner wall of the upper half of the tank 1. Subsequently, the lifting assembly drives the movable ring plate 9 to descend, causing the lower half of the stirring ring plate 13 to come into contact with the inner wall of the lower half of the tank 1. The stirring ring plate 13 can then scrape off the pulp adhering to the inner wall of the lower half of the tank 1, thereby cleaning the pulp adhering to the inner wall of the tank 1 and preventing the pulp adhering to the inner wall from affecting the stirring efficiency and pulp uniformity.
