Description

Technical Field

[0001] This utility model relates to the technical field of household paper production equipment, and in particular to a device for uniformly mixing household paper fibers. Background Technology

[0002] In the production of tissue paper, the uniform mixing of paper fiber materials with other additives (such as liquid binders and chemical auxiliaries) is a crucial step, directly affecting product quality and performance. Traditional mixing equipment is showing its limitations when dealing with paper fiber materials.

[0003] On the one hand, conventional equipment has a simple mixing structure, relying mainly on simple blade rotation, which makes it difficult to fully tumble the fibrous material. Paper fibers are lightweight and easily entangle and clump together. The single mixing mode leads to uneven mixing of materials and inconsistent product quality. For example, some papers are far below the standard values ​​in key indicators such as strength and water absorption due to poor fiber dispersion.

[0004] On the other hand, when adding liquid materials into the mixing tank, traditional devices cannot disperse the liquid quickly and evenly, often resulting in localized liquid accumulation or slow mixing, which significantly prolongs the mixing time and reduces production efficiency. Moreover, after mixing, the residual material on the inner wall of the mixing tank is difficult to clean, and manual cleaning is laborious and time-consuming, which not only increases production costs, but also easily affects the purity of subsequent batches of materials due to incomplete cleaning.

[0005] Based on the above-mentioned shortcomings, this utility model proposes a device for uniformly mixing household paper fibers.

[0036] Reference Figure 1-7 A device for uniformly mixing household paper fibers includes a mixing tank 1, a hollow shaft 2, a motor 21, a liquid adding component, multiple material guiding troughs 11, a turning component, a stirring component, a cleaning component, a transmission component, and a discharge pipe 12.

[0037] Hollow shaft 2 is rotatably installed in the center of mixing barrel 1. Motor 21 is fixedly installed on the top of mixing barrel 1, and the output shaft of motor 21 is axially fixedly connected to the top of hollow shaft 2. Multiple guide grooves 11 are connected to mixing barrel 1 and are arranged radially based on the axis of mixing barrel 1. Discharge pipe 12 is fixedly installed on the bottom of the outside of mixing barrel 1 and is in communication with hollow barrel. A control valve is provided on discharge pipe 12.

[0038] The liquid addition assembly is located at the bottom of the mixing tank 1 and connected to the hollow shaft 2;

[0039] The liquid addition assembly includes a delivery pump 22, a check valve, a dispersion tube 23, and multiple nozzles. The delivery pump 22 is fixedly installed at the bottom of the mixing tank 1. The outlet of the delivery pump 22 is sealed and rotatably connected to the hollow shaft 2 and is equipped with a check valve. Multiple dispersion tubes 23 connected to the hollow shaft 2 are radially fixedly installed on the hollow shaft 2. Multiple downward-facing nozzles are fixedly installed on the dispersion tubes 23.

[0040] In the above method, the liquid addition component facilitates the addition of liquid materials into the mixing tank 1 and allows them to disperse quickly within the mixing tank 1.

[0041] A rotating plate 4 is fixedly installed on the hollow shaft 2, and the stirring assembly is set on the rotating plate 4;

[0042] The stirring assembly includes multiple rotating shafts 41, multiple stirring rods 42, multiple connecting rods 43, multiple guide pins 44, multiple hollow cylinders 45, and multiple guide grooves 451. Multiple rotating shafts 41 are rotatably mounted on the rotating plate 4, which are parallel to each other with the hollow shafts 2. Multiple mounting ports are opened on each of the multiple rotating shafts 41. Rotating pins are rotatably mounted on the inner sidewall of the mounting ports. Stirring rods 42 are radially fixedly mounted on the rotating pins. The same connecting rod 43 is radially rotatably mounted on the multiple stirring rods 42 located on the same rotating shaft 41. Guide pins 44 are radially rotatably mounted on the connecting rod 43. Hollow cylinders 45 are fixedly mounted on the bottom side of the rotating plate 4, with the rotating shafts 41 as the center. Elliptical guide grooves 451 are opened on the outer side of the hollow cylinders 45. Guide pins 44 are slidably mounted in the corresponding guide grooves 451.

[0043] In the above method, the stirring assembly can drive multiple rotating shafts 41, multiple stirring rods 42 and multiple connecting rods 43 to perform stirring operations when the rotating plate 4 rotates with the hollow shaft 2. At the same time, it can control the multiple stirring rods 42 to swing up and down when the rotating shaft 41 rotates.

[0044] The mixing component is mounted on the hollow shaft 2;

[0045] The mixing assembly includes a spiral blade 3, a fixed sleeve 31, and a sliding sleeve 32. A fixed sleeve 31 is fixedly installed on the outside of the hollow shaft 2, a spiral blade 3 is fixedly installed on the outside of the fixed sleeve 31, and a sliding sleeve 32 that is slidably connected to the hollow shaft 2 is fixedly installed on the spiral blade 3.

[0046] In the above method, the mixing component can be set to mix the paper fiber material in the mixing tank 1 when the hollow shaft 2 drives the spiral blade 3 to rotate. The paper fiber material will deform under the reaction force of the paper fiber material. As the rotation speed of the hollow shaft 2 changes, the force on the spiral blade 3 by the paper fiber material will also change. Thus, the effect of adjusting the range of action on the paper fiber can be achieved according to the different rotation speeds of the hollow shaft 2.

[0047] The cleaning component is located on the bottom side of the rotating plate 4 and connected to the hollow shaft 2, and the cleaning component is adapted to the inner wall of the mixing tank 1;

[0048] The cleaning components include a spiral scraper 6 and a cleaning scraper 61. The spiral scraper 6 is fixedly installed on the bottom side of the rotating plate 4, and the cleaning scraper 61 is fixedly installed on the spiral scraper 6. The cleaning scraper 61 is radially fixedly installed on the outside of the hollow shaft 2, and the spiral scraper 6 and the cleaning scraper 61 are in contact with the inner side wall and the bottom inner wall of the mixing tank 1, respectively.

[0049] In the above method, the cleaning components can clean the inner wall and bottom inner wall of the mixing barrel 1 when the rotating plate 4 rotates. At the same time, the spiral scraper 6 can stir the paper fiber material near the inner wall of the mixing barrel 1, thereby further improving the uniformity and efficiency of mixing.

[0050] The transmission assembly is located on the top inner wall of the mixing tank 1 and is connected to the stirring assembly;

[0051] The transmission assembly includes a gear disk 5 and multiple gears 51. The top ends of multiple rotating shafts 41 extend above the rotating plate 4 and are respectively fixedly fitted with gears 51. A gear disk 5 is fixedly installed on the top inner wall of the mixing barrel 1, and multiple gears 51 mesh with the gear disk 5.

[0052] In the above method, the transmission component can achieve the effect of rotation when the rotating plate 4 drives multiple rotating shafts 41 to revolve around the hollow shaft 2, thereby greatly improving the mixing effect.

[0053] In this embodiment, in order to effectively improve the turning effect of paper fiber material in mixing tank 1 and achieve the effect of rapid mixing of paper fiber, the spiral blades 3 and spiral scrapers 6 have opposite spiral directions, and the stirring rod 42, rotating shaft 41 and connecting rod 43 are all located within the range between the spiral blades 3 and spiral scrapers 6.

[0054] In this embodiment, in order to facilitate the staff to understand the amount of material in the mixing barrel 1, an observation window 13 is provided on the side wall of the mixing barrel 1, and the observation window 13 is arranged in a strip shape.

[0055] In this embodiment, in order to ensure that it provides stable support for the rotating shaft 41 while avoiding material contamination of the gear 51 and gear disk 5 and affecting its normal transmission effect, the rotating plate 4 is circular and located above the position where the guide trough 11 communicates with the mixing barrel 1.

[0056] The circuits, electronic components, and module mechanisms involved all employ existing technologies, which can be fully implemented by those skilled in the art, and need no further explanation. The content protected by this application does not involve any improvement to the software, circuits, or methods.

[0057] Working principle: In use, first connect the power supply, then introduce the required paper fiber material into the mixing tank 1 from different feed troughs 11, and start the motor 21. The motor 21 controls the hollow shaft 2 to drive the rotating plate 4 to rotate, causing multiple rotating shafts 41 to revolve around the hollow shaft 2. Simultaneously, with the cooperation of the gear disc 5 and gear 51, the rotating shafts 41 can rotate on their own axis, thereby improving the mixing efficiency. Furthermore, through the cooperation of the hollow cylinder 45, connecting rod 43, guide pin 44, and elliptical guide groove 451, multiple stirring rods 42 can be controlled to swing up and down during the rotation of the rotating shaft 41, further enhancing the mixing effect. The rotation of plate 4 will drive the spiral scraper 6 and cleaning scraper 61 to rotate around the hollow shaft 2. This not only enables real-time cleaning of the inner wall and bottom inner wall of the mixing tank 1, but also, because the spiral direction of the spiral scraper 6 is set opposite to that of the spiral blade 3, it can further improve the mixing effect of paper fibers in the mixing tank 1. During the paper fiber mixing process, the required liquid material is delivered into the hollow shaft 2 by the delivery pump 22. This liquid material is evenly sprayed into the mixing tank 1 through multiple dispersion pipes 23 and multiple downward-facing nozzles. This method of adding liquid material is conducive to rapid and uniform mixing with paper fiber material.

[0058] The present invention provides a detailed description of a device for uniformly mixing household paper fibers. Specific embodiments have been used to illustrate the principle and implementation of the present invention. These embodiments are merely illustrative and are intended to help understand the method and core concept of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from its principles, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
