Description

Technical Field

[0001] This utility model relates to a pulping device for paper product manufacturing, belonging to the field of paper product manufacturing technology. Background Technology

[0002] Wood pulp is the main raw material for papermaking. Its production process can be roughly divided into: cutting: cutting wood into wood chips of various sizes; cooking: putting the wood chips into a cooking pot to cook and soften the wood chips; beating: putting the cooked wood chips into a beating machine and adding water and chemical agents (such as bleach) for beating treatment. During beating, it is necessary to stir to ensure that the wood fibers are evenly dispersed. In order to improve the efficiency of the beating machine, the wood chips can be crushed into small pieces before being put into the beating machine.

[0003] For example, Chinese utility model patent CN220813211 U discloses a pulping device for paper product manufacturing, including a crusher. The crusher has a pair of crushing hubs for crushing. A feed inlet is provided above the crushing hubs, and a guide pipe is provided below the crushing hubs. The bottom of the guide pipe is connected to the inside of the pulping mechanism. The pulping mechanism is hollow and has a rotating shaft. The top of the rotating shaft passes through the inner wall of the pulping mechanism and is connected to the output end of a first motor. Several blades are installed on the part of the rotating shaft inside the pulping mechanism. A water inlet is provided at the top of the pulping mechanism, and a discharge port with a valve is provided at the bottom of the pulping mechanism.

[0004] The above solution has the following shortcomings in practical use:

[0005] The proposed solution uses a crushing hub on a crusher to crush wood chips into small pieces. These small pieces then enter a pulping mechanism along a feed pipe for pulping. However, in actual use, the above structure is quite complex, and it cannot repeatedly crush the wood chips, which can easily lead to incomplete crushing and poor uniformity during pulping. Utility Model Content

[0006] The purpose of this invention is to provide a pulping device for paper product manufacturing to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] Preferably, a flow guide ring is provided on the upper surface of the lower plate.

[0010] Preferably, a positioning seat is provided in the middle of the upper surface of the lower plate, and a notch corresponding to the positioning seat is provided on the lower surface of the upper plate.

[0011] Preferably, the execution unit includes a limiting ring connected to the upper plate body, a connecting ring rotatably connected to the lower surface of the limiting ring, a lifting platform provided on the inner circumferential surface of the connecting ring, and a cylinder for driving the lifting platform to move up and down on the top of the pulping tank.

[0012] Preferably, the execution unit further includes a motor, the output shaft of which extends into the interior of the pulping tank and is provided with a drive shaft, the bottom end of which passes through the upper plate and is rotatably connected to the positioning seat.

[0013] Preferably, the lower plate body has a through hole corresponding to the drive shaft, the inner wall of the through hole is provided with a limit block, and the drive shaft has a limit groove corresponding to the limit block.

[0014] Preferably, a feeding platform is provided on one side of the top of the pulping tank, and a discharge pipe is provided on one side of the bottom of the pulping tank.

[0015] Preferably, a second cylinder is provided at the bottom of the pulping tank, and the output end of the second cylinder extends into the interior of the pulping tank and is provided with a blocking plate.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] During use, the operator puts the softened wood chips into the pulping tank. The upper disc is then driven to move downwards by the actuator. When the wood chips come into contact with the lower disc, the upper disc rotates to grind and crush the wood chips. The chips that meet the requirements pass through the filter holes, while the chips that do not meet the requirements are continuously crushed, thus ensuring that the wood chips are fully broken down. At the same time, the upper disc can also stir the liquid in the pulping tank, so that the wood fibers are evenly dispersed, ensuring the dispersion effect. Moreover, the entire device has a simple structure and low production cost. Attached Figure Description

Detailed Implementation

[0024] 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.

[0025] Please see Figures 1-4 This utility model provides a technical solution:

[0026] like Figure 1 and Figure 2 As shown, a pulping device for paper product manufacturing includes a frame 1, a pulping tank 2 mounted on the frame 1, a lower plate 5 mounted in the lower part of the pulping tank 2, a guide ring 6 mounted on the upper surface of the lower plate 5, and an upper plate 7 mounted above the lower plate 5 corresponding to the guide ring 6. The guide ring 6 allows wood chips to gather, thus preventing the wood chips from being unable to be crushed. Both the lower plate 5 and the upper plate 7 have several filter holes 8, and both the lower plate 5 and the upper plate 7 have several crushing teeth 9 on opposite sides. An execution unit is mounted on the pulping tank 2, which drives the upper plate 7 to move downward. When the wood chips come into contact with the lower plate 5, the upper plate 7 is driven to rotate to grind and crush the wood chips. The crushed wood chips that meet the requirements pass through the filter holes 8, while the wood chips that do not meet the requirements are continuously crushed, thus ensuring that the wood chips are fully crushed. At the same time, the upper plate 7 can also stir the liquid in the pulping tank 2, thereby making the wood fibers evenly dispersed and ensuring the dispersion effect.

[0027] Furthermore, a feeding platform 3 is provided on one side of the top of the pulping tank 2, and a discharge pipe 4 is provided on one side of the bottom of the pulping tank 2.

[0028] Furthermore, a second cylinder 19 is provided at the bottom of the pulping tank 2, and the output end of the second cylinder 19 extends into the interior of the pulping tank 2 and is provided with a blocking plate 20.

[0029] Specifically, by controlling the operation of cylinder 219 to drive the blocking plate 20 to move upward, the blocking plate 20 is brought into contact with the lower surface of the lower plate 5, thereby controlling the wood pulp to be discharged through the discharge pipe 4. After pulping is completed, by controlling the operation of cylinder 219 to drive the blocking plate 20 to move downward, the blocking plate 20 is separated from the lower plate 5, and then the wood pulp is discharged through the discharge pipe 4.

[0030] Furthermore, a positioning seat 10 is provided in the middle of the upper surface of the lower plate 5, and a notch corresponding to the positioning seat 10 is provided on the lower surface of the upper plate 7.

[0031] like Figure 3 and Figure 4 As shown, the execution unit includes a limiting ring 11, which is connected to the upper plate 7. A connecting ring 12 is rotatably connected to the lower surface of the limiting ring 11. A lifting platform 13 is provided on the inner circumferential surface of the connecting ring 12. A cylinder 14 is provided on the top of the pulping tank 2 to drive the lifting platform 13 to move up and down. When it is necessary to control the upper plate 7 to move up and down, the lifting platform 13 is driven by the cylinder 14 to move up and down. During the crushing of wood chips, the upper plate 7 is controlled to move up and down at regular intervals so that the crushed wood fibers are fully mixed in the solution.

[0032] Furthermore, the execution unit also includes a motor 15, the output shaft of which extends into the interior of the pulping tank 2 and is provided with a drive shaft 16. The bottom end of the drive shaft 16 passes through the upper plate 7 and is rotatably connected to the positioning seat 10.

[0033] Furthermore, the lower plate 5 is provided with a through hole 17 corresponding to the drive shaft 16, the inner wall of the through hole 17 is provided with a limit block 18, and the drive shaft 16 is provided with a limit groove corresponding to the limit block 18.

[0034] When the upper disc 7 moves down to push the softened wood chips, and when the wood chips come into contact with the lower disc 5 and reach a certain pressure, the motor 15 is started. With the cooperation of the limit block 18 and the limit groove, the drive shaft 16 drives the upper disc 7 to start rotating, and the wood chips are fully crushed under the action of the crushing teeth 9.

[0035] The workflow of this embodiment is as follows: The worker puts the softened wood chips into the pulping tank 2 through the feeding platform 3, and then controls the execution unit to make the upper plate 7 push the wood chips down. When the wood chips come into contact with the lower plate 5, the upper plate 7 is driven to rotate to grind and crush the wood chips. During this process, the execution unit controls the upper plate 7 to move upward first and then downward multiple times, so that the wood fibers that meet the requirements enter the solution in the pulping tank 2 through the filter holes 8 on the upper plate 7. At the same time, the upper plate 7 can also stir the liquid in the pulping tank 2, so that the wood fibers are evenly dispersed.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
