Description

Technical Field

[0001] The utility model belongs to the technical field of pulp stirrers, and particularly relates to a pulp stirrer for carton production. Background Technique

[0002] Cartons are the most widely used packaging products, which can be divided into corrugated cartons and single-layer cardboard boxes according to different materials used. In the process of carton processing, the most important raw material - pulp is needed. Pulp is processed from certain plants and is the basic raw material for papermaking. Usually, the plants used as pulping raw materials can be divided into 4 categories: stem fiber category, bast fiber category, seed hair fiber category, and wood fiber category, among which the wood fiber category is the most important.

[0003] In the process of implementing the present utility model, the inventor found that there are at least the following problems in this technology: when producing pulp, a stirrer is needed to mix and stir all its raw materials. However, the current pulp stirrers, such as the patent with the application number CN202223536535.X - a pulp stirrer, usually only roughly stir the raw materials with a stirring structure. In the material cylinder for accommodating the raw materials, there are some positions where the raw materials are always at the edge and cannot be touched by the stirring structure, resulting in uneven material components after stirring.

[0004] Therefore, we propose a pulp stirrer for carton production to solve the above problems. Content of the Utility Model

[0005] The main purpose of the present utility model is to provide a pulp stirrer for carton production, which can stir the pulp production materials at different positions in the material cylinder, increasing the stirring range and making the material components after stirring more balanced, and can effectively solve the problems in the background technique.

[0006] In order to achieve the above purpose, the present utility model adopts the following technical scheme:

[0007] A pulp stirrer for carton production includes a base and a material cylinder located above the base. A lower drive motor is fixed at the bottom of the base. Above the output shaft of the lower drive motor, a support shaft is coaxially connected. A turntable is coaxially welded on the support shaft, and the material cylinder is embedded in the turntable and welded to the turntable;

[0008] Above the base, a U-shaped mounting frame is welded. At the center of the top wall of the mounting frame, an upper driving motor is vertically installed. At the bottom wall of the mounting frame, a gear box is welded. The interior of the gear box is of a hollow design. Five lower edge shafts are vertically arranged inside the gear box. One of the lower edge shafts is located at the center of the inner cavity of the gear box and is coaxially connected to the output shaft of the upper driving motor. The central axis of this lower edge shaft coincides with the central axis of the material cylinder. A sun gear is fixedly sleeved on the lower edge shaft located at the center of the inner cavity of the gear box. The other four lower edge shafts are distributed on the four sides of this lower edge shaft. Planet gears are fixedly sleeved on the other four lower edge shafts. All four planet gears are meshed with the sun gear. Coaxially connected below the five lower edge shafts are inner support shafts respectively. The five inner support shafts are all rotatably connected to the bottom wall of the gear box, making the structural stability of the five inner support shafts stronger. Multiple groups of sub-stirring rods for stirring the pulp production materials are fixedly welded on each inner support shaft.

[0009] As a preferred implementation, a groove is formed on the bottom wall of the base. The lower driving motor is vertically installed on the bottom wall of the groove, making the structure of the lower driving motor stable. Both the lower driving motor and the upper driving motor need to be powered separately by external power facilities, and the lower driving motor is hidden in the groove, providing it with good protection.

[0010] As a preferred implementation, a top moving groove is formed on the top wall of the base. The support shaft is rotatably connected to the bottom wall of the top moving groove, enabling the support shaft to rotate stably under the drive of the lower driving motor and driving the turntable and the material cylinder thereon to rotate at a uniform and slow speed.

[0011] As a preferred implementation, all five lower edge shafts are located in the inner cavity of the gear box and are rotatably connected to the gear box, enabling all five lower edge shafts and the sun gear or planet gears thereon to rotate stably.

[0012] As a preferred implementation, a discharge pipe is fixedly connected to one side wall of the material cylinder, and a valve is installed on the discharge pipe. The valve can be electric or manual and is used to control the opening and closing of the material cylinder.

[0013] As a preferred implementation, multiple groups of sub-stirring rods on each inner support shaft are evenly distributed along the vertical direction, and each group of sub-stirring rods is symmetrically welded on both sides of the outer wall of the inner support shaft, enabling the inner support shaft to drive the multiple groups of sub-stirring rods thereon to stir the pulp production materials at different depths in the inner cavity of the material cylinder when rotating.

[0014] In summary, the technical effects and advantages of the present utility model:

[0015] The pulp stirrer for carton production drives the operation of five inner support shafts and the sub-divided stirring rods thereon through the operation of the upper drive motor, and stirs the pulp production materials in the cylinder more carefully. At the same time, it cooperates with the operation of the lower drive motor to drive the cylinder to rotate slowly and evenly, so as to facilitate the stirring of the pulp production materials at different positions in the cylinder, increasing the stirring range and making the components of the stirred materials more balanced.

[0016] When the upper drive motor of the pulp stirrer for carton production operates, it will drive the operation of five inner support shafts and the sub-divided stirring rods thereon to stir the pulp production materials. Then, the lower drive motor is driven to operate, so that it drives the support shaft, the turntable and the cylinder to operate, and while the sub-divided stirring rods on the five inner support shafts are operating, the cylinder is also driven to operate, so that the sub-divided stirring rods on the five inner support shafts can reach the pulp production materials at various positions in the inner cavity of the cylinder, making the components of the stirred materials more uniform.
