Description

Technical Field

[0001] This utility model relates to the field of crushing device technology, specifically a wood fiber crushing device for processing coated whiteboard paper. Background Technology

[0002] Coated white paperboard is a type of paperboard made from bleached wood pulp as the surface layer, coated on one side and then calendered. It is commonly used in the production of packaging boxes. During the production of coated white paperboard, the wood fibers need to be broken down as much as possible to ensure the quality of the coated white paperboard by improving the quality of the wood pulp used for the surface coating. Currently, the breaking down of wood fibers is usually achieved by a shredder. However, in common shredders, the blade positions are fixed, and the size of the crushing space is not easily adjusted according to the weight of the wood fibers. The high-speed rotating blades generate airflow, which can cause the wood fibers to shift and move away from the blades when they are close to them. This results in some wood fibers not being completely broken down, affecting the quality of the wood pulp preparation and hindering the production and processing of coated white paperboard. Utility Model Content

During the crushing process, the crushing position can be adjusted according to the needs. By crushing wood fibers at different positions in the crushing tank, the quality of wood fiber crushing is ensured. In addition, the size of the crushing space can be adjusted according to the weight of wood fibers during use to prevent wood fibers from being blown away from the blades by the airflow during the crushing process, thus ensuring effective crushing of wood fibers, ensuring the quality of wood pulp preparation, and facilitating the production and processing of coated whiteboard paper. This can effectively solve the problems in the background technology.

Detailed Implementation

[0015] 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.

[0016] Please see Figure 1-4 This utility model provides a technical solution: a wood fiber crushing device for processing coated whiteboard paper, including a base plate 1, a crushing tank 2 and a lifting assembly on the upper side of the base plate 1. The crushing tank 2 is used to place wood fibers and to crush them. A drive assembly is provided at the telescopic end of the lifting assembly. A connecting shaft 7 is installed on the drive shaft of the drive assembly. The crushing assembly located inside the crushing tank 2 is installed at the end of the connecting shaft 7. The height of the crushing assembly can be adjusted by the lifting assembly. During use, the height of the crushing assembly can be adjusted by moving it inside the crushing tank 2 as needed. The crushing assembly is driven to rotate by the drive assembly to crush the wood fibers at different positions inside the crushing tank 2.

[0017] A limiting plate 12 is slidably installed inside the crushing tank 2, and the side of the limiting plate 12 contacts the inside of the crushing tank 2. The limiting plate 12 is slidably connected to the connecting shaft 7. A positioning component for adjusting the height of the limiting plate 12 is provided on the side of the crushing tank 2. The limiting plate 12 restricts the wood fibers inside the crushing tank 2. During crushing, the position of the limiting plate 12 is adjusted according to the weight of the wood fibers, thereby adjusting the size of the wood fiber crushing space. This prevents the wood fibers from being moved away by the airflow generated by the high-speed rotating crushing component due to an excessively large crushing space, thus avoiding them from being crushed. By limiting the crushing space, effective crushing of wood fibers is ensured, which is convenient for the production and processing of coated white paperboard.

[0018] The top of the crushing tank 2 is open, and a sealing cover 3 is provided at the top opening of the crushing tank 2. The sealing cover 3 is detachable. The top opening of the crushing tank 2 can be opened by moving the sealing cover 3, which facilitates the loading and unloading of wood fibers inside the crushing tank 2. An annular base 17 adapted to the crushing tank 2 is provided on the upper side of the bottom plate 1. The crushing tank 2 is movably disposed in the annular base 17. The annular base 17 is used to limit the movement of the crushing tank 2, reduce the shaking of the crushing tank 2 when the wood fibers are crushed, and improve the stability of the crushing tank 2 during use.

[0019] An mounting cylinder 11 is fixed to the side of the sealing cover 3, and a limiting cylinder 13 is fixed to the side of the limiting plate 12. The connecting shaft 7 is movably disposed within the mounting cylinder 11 and the limiting cylinder 13. The mounting cylinder 11 facilitates the movable connection between the connecting shaft 7 and the sealing cover 3, and the sealing cover 3 limits the connecting shaft 7 through the mounting cylinder 11, thereby improving the stability of the connecting shaft 7 during rotation. The limiting cylinder 13 facilitates the movable connection between the connecting shaft 7 and the limiting plate 12, and the limiting cylinder 13 is used to increase the contact area between the limiting plate 12 and the connecting shaft 7, thereby improving the stability of the limiting plate 12 when it moves up and down and preventing the limiting plate 12 from tilting during movement.

[0020] A positioning cylinder 15 is fixed to the side of the sealing cover 3, and a positioning rod 14 is fixed to the side of the limiting plate 12. The positioning rod 14 is slidably installed inside the positioning cylinder 15. The sealing cover 3 limits the positioning rod 14 through the positioning cylinder 15. The upper part of the side of the positioning rod 14 is threaded, and a positioning nut 16 is threaded to the outer side of the positioning rod 14. The positioning nut 16 is located on the upper side of the sealing cover 3. The positioning nut 16 is used to position the limiting plate 12 at the bottom of the positioning rod 14. By adjusting the movement of the positioning nut 16 on the positioning rod 14, the setting height of the limiting plate 12 can be adjusted, thereby adjusting the crushing space. It should be noted that after the wood fiber is put into the crushing tank 2, a certain space should be reserved between the limiting plate 12 and the wood fiber to facilitate the expansion of the volume of the wood fiber after crushing. If the crushing component moves too far upward due to improper operation during the crushing process, the limiting plate 12 can automatically move upward under the squeezing action of the crushing component to avoid collision with the blade.

[0021] The lifting assembly includes an electric telescopic cylinder 4. The fixed end of the electric telescopic cylinder 4 is fixed to the upper side of the base plate 1. An installation frame 5 is installed at the telescopic end of the electric telescopic cylinder 4. The drive assembly is set inside the installation frame 5. During the wood fiber crushing process, the crushing position of the crushing assembly can be adjusted by controlling the electric telescopic cylinder 4 to drive the drive assembly to lift and lower, so as to facilitate the crushing of wood fibers at different positions. The lifting assembly can also be a servo electric cylinder, hydraulic cylinder, etc.

[0022] The drive assembly includes a motor unit 6 installed in the mounting frame 5. One end of the connecting shaft 7 is connected and fixed to the drive shaft of the motor unit 6. By controlling the operation of the motor unit 6, the connecting shaft 7 is driven to rotate, thereby driving the crushing assembly to crush the wood fiber. A limit plate 12 is fixed to the side of the connecting shaft 7. The limit plate 12 is rotatably set on the upper side of the mounting frame 5. The limit plate 12 is used to reduce the force exerted by the connecting shaft 7 on the motor unit 6, reduce the impact of the crushing assembly's own weight on the motor unit 6, and ensure the service life of the motor unit 6.

[0023] The bottom of the connecting shaft 7 is fixed with a mounting base 8. The crushing assembly includes a cutter holder 9 and several blades 10. The blades 10 are all fixed on the cutter holder 9. The cutter holder 9 is detachably mounted on the mounting base 8. The connecting shaft 7 drives the cutter holder 9 to rotate. The blades 10 mounted on the cutter holder 9 crush the wood fibers in the crushing tank 2. The blades 10 are easily replaced and maintained by disassembling and assembling the cutter holder 9 on the mounting base 8.

[0024] The electric telescopic cylinder 4 and motor group 6 used in this utility model are common electronic components in the prior art. Their working methods and circuit structures are known technologies. The operation of the electric telescopic cylinder 4 and motor group 6 is controlled by an externally set switch group or PLC controller. This method is a common technical means used by technicians and will not be described in detail here.

[0025] This wood fiber crushing device for coated whiteboard paper processing allows for adjustment of the crushing position as needed during the crushing process. By crushing wood fibers at different locations within the crushing tank, the quality of wood fiber crushing is ensured. Furthermore, the size of the crushing space can be adjusted according to the weight of the wood fibers during use to prevent the wood fibers from being displaced by the airflow and moving away from the blades during the crushing process. This ensures effective crushing of the wood fibers, guarantees the quality of wood pulp preparation, and facilitates the production and processing of coated whiteboard paper.
