Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of pulp molding processing, and specifically to a production device and process for pulp molding. Background Art
[0002] Pulp molding is an innovative three-dimensional papermaking technology. It mainly converts waste paper into pulp and uses a mold for shaping to produce various shaped and purposeful paper products. Its processing process includes multiple links such as collection and classification of waste paper, crushing treatment, pulping, mold forming, demolding and drying, and post-treatment. First, the waste paper is processed by a crushing device and cut into small pieces to increase the surface area for subsequent pulping. Then, the crushed paper pieces are fed into a pulping tank, mixed with water and additives, and uniformly formed into pulp through stirring and heating. In the mold forming stage, the pulp is poured into a specifically designed mold, and through pressing and drying, the pulp gradually solidifies and forms. After demolding, the paper product is further dried to remove excess moisture to ensure the strength and stability of the product, where the fluidity and viscosity of the slurry determine the forming effect; For example, a production device and process for pulp molding disclosed in the application publication number CN118756513A includes a mixing cylinder. The upper end of the mixing cylinder abuts against a lid, and a reciprocating motor is installed on the upper end of the lid. The output shaft of the reciprocating motor is fixedly connected with a rotating rod. The waste paper and paper can be crushed by a crushing mechanism, and then the paper scraps fall into the interior of the mixing cylinder. Thus, the reciprocating motor drives the rotating rod to rotate, and the rotating rod can drive the stirring rod, the scraper, and the wire mesh to rotate. The stirring rod can play a role in stirring. However, in the above technical solution, when using the crushing mechanism and the stirring mechanism to crush and pulp the paper and the slurry respectively, at least two independent motor devices are required for driving operation. And when the stirring mechanism operates, the slurry always mixes in one direction. Due to the high viscosity and density of the slurry, the unidirectional and forward stirring method is difficult to generate an effective turbulent effect in the tank, resulting in the fibers and bubbles in the slurry not being evenly distributed, that is, the fibers in the slurry gather in some areas and are sparser in other areas, making the pulp molding finished products processed from the pulp have problems of uneven strength and rough surface. Summary of the Invention
[0003] The purpose of the present invention is to provide a production device and process for pulp molding. The gear pair roller type crusher at the top of the conical feeding cylinder crushes the paper material and sends it into the pulping tank through a feeding box. The in - center slurry mixing assembly in the pulping tank continuously mixes the paper material and the slurry. During this process, the rotating power of the in - center slurry mixing assembly is transmitted to the cam - type dynamic turbulent slurry mixing assembly through a three - zone gear transmission structure, and the cam - type dynamic turbulent slurry mixing assembly uses a bevel gear drive to drive the gear pair roller type crusher to work, realizing single - motor drive operation and the generation of a stirring turbulent effect, so as to solve the problems raised in the above background art.

At one side of the top end of the pulping tank, a bevel gear transmission is installed for connecting the gear pair roller type crusher and one of the cam type dynamic turbulent mixing pulp assemblies.
[0005] Preferably, a feeding manhole is installed on the outer wall of one side of the pulping tank, and a pulp discharge pipe is installed on the outer wall of the pulping tank below the feeding manhole. A switching valve is installed at the end of the pulp discharge pipe far away from the pulping tank.
[0006] Preferably, a material pipe is installed at one side of the bottom end of the feeding guide box. The bottom end of the material pipe penetrates through the outside of the partition disk and extends into the inside of the pulping tank. The extension line of the central axis of the material pipe is perpendicular to the extension line of the central axis of the feeding manhole.
[0007] Preferably, the central mixing pulp assembly is composed of a reduction motor, a central shaft, and a cage column type stirrer. The reduction motor is installed on the outer wall of one side of the feeding guide box. The central shaft is rotatably installed at the central position inside the partition disk. The cage column type stirrer is fixed at the bottom end of the central shaft. The top end of the central shaft is fixedly connected to the bottom end of the output shaft of the reduction motor through a coupling.
[0008] Preferably, the cage column type stirrer includes circular steel disks fixed at both ends of the surface of the central shaft and a plurality of annular equally spaced C-shaped steel bars welded and fixed between the two circular steel disks.
[0009] Preferably, the three-zone gear transmission structure includes a central gear disk fixed at one end of the surface of the central shaft and a plurality of annular equally spaced driven gears rotatably installed at the edge position of the top end of the partition disk. The driven gears are meshed with the central gear disk. The bottom end of the central gear disk is rotatably connected to the top end of the partition disk. The driven gears are connected to the cam type dynamic turbulent mixing pulp assembly.
[0010] Preferably, both the driven gears and the cam type dynamic turbulent mixing pulp assemblies are provided in three.
[0011] Preferably, the cam-type dynamic turbulent pulp mixing assembly includes a T-shaped shaft seat fixed inside the partition disc, a driven shaft rotatably installed inside the T-shaped shaft seat, a disc-shaped cam fixed to the bottom end of the driven shaft, and a C-shaped vertical frame hingedly installed at the bottom end of the T-shaped shaft seat. One side of the top end of the C-shaped vertical frame is rotatably installed with a roller, and the roller is located in the groove of the disc-shaped cam. A pointed feed plate is fixed on the outer wall of one side of the C-shaped vertical frame. The top end of one of the driven shafts penetrates to the outside of the pulp making tank and drives the gear pair roller mill to work through a bevel gear drive.
[0012] Preferably, the bevel gear drive includes a U-shaped shaft frame fixed on one side of the top end of the pulp making tank, a horizontal shaft rotatably installed inside the U-shaped shaft frame, and bevel gears installed at the opposite ends of the horizontal shaft and a straight bevel gear.

[0013] The present invention also provides a production process for pulp molding. The production equipment for pulp molding as described above includes the following steps: S101: First, prepare a sufficient amount of waste paper materials, classify the waste paper materials, and remove impurities such as incompatible materials like plastics and metals. After preliminary treatment, send the qualified raw materials to the top opening position of the gear pair roller mill. S102: After the raw materials are prepared, the staff starts the middle pulp mixing assembly to work. The rotary power of the middle pulp mixing assembly is transmitted to each cam-type dynamic turbulent pulp mixing assembly through a three-zone gear transmission structure. And one of the cam-type dynamic turbulent pulp mixing assemblies drives the gear pair roller mill to run by using a bevel gear drive. At this time, the crushing rollers of the gear pair roller mill apply pressure to the paper materials and crush them into small paper scraps. The crushed paper scraps smoothly enter the guide box and the pulp making tank through the conical feed tube. S103: Once the paper materials are crushed and enter the pulp making tank, the middle pulp mixing assembly continuously stirs the paper materials and water to make them fully mixed to form a slurry. During the mixing process, the rotary power of the middle pulp mixing assembly is transmitted to the cam-type dynamic turbulent pulp mixing assembly through a three-zone gear transmission structure. The cam-type dynamic turbulent pulp mixing assembly generates a turbulent effect, enhancing the fluidity and uniformity of the slurry. S104: When the slurry is prepared, the slurry is discharged from the pulp making tank. After discharging, the slurry is sent to subsequent molding equipment for processing.
[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: The production equipment and process of the pulp molding combine the gear pair roller crusher at the top of the conical feeding cylinder with the central mixing pulp assembly, adopt the design of the three-zone gear drive structure and the cam-type dynamic turbulent mixing pulp assembly. Among them, by integrating the power systems of the gear pair roller crusher and the mixing pulp assembly into a single-motor drive, the power complexity and cost of the equipment are significantly reduced, making the operation of the entire equipment more coordinated, reducing the construction cost and the later use and maintenance costs; Secondly, during the continuous mixing of the paper material and the slurry by the central mixing pulp assembly, the power is effectively transmitted to the cam-type dynamic turbulent mixing pulp assembly through the three-zone gear drive structure, making the mixing process faster and more uniform, and avoiding the aggregation phenomenon caused by traditional one-way stirring. Since the cam-type dynamic turbulent mixing pulp assembly can continuously generate a turbulent effect, the fibers in the slurry can be more evenly dispersed. The good mixing effect not only reduces the precipitation of the pulp, but also ensures better fluidity and formability of the pulp during the molding process, thereby improving the uniformity and strength of the pulp molding products.

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0018] Embodiment 1 is given by Figures 1 to 5 The present invention includes a pulping tank 1. A conical feeding tube 3 is installed at one side edge position at the top of the pulping tank 1, and a gear pair roller type crusher 4 is installed at the opening position at the top of the conical feeding tube 3. The conical feeding tube 3 enables the material to flow smoothly under the action of gravity and reduces the blockage phenomenon. A partition disc 7 is fixed at one end inside the pulping tank 1, and a material guiding box 5 communicating with the conical feeding tube 3 is installed at one side edge position at the top of the partition disc 7; A middle mixing pulp assembly 8 is provided at the central position inside the pulping tank 1. A plurality of equally spaced cam type dynamic turbulent mixing pulp assemblies 10 are installed at the edge position at the top of the partition disc 7.

A bevel gear transmission 11 for connecting the gear pair roller type crusher 4 and one of the cam type dynamic turbulent mixing pulp assemblies 10 is installed at one side of the top of the pulping tank 1.
[0019] A production process of pulp molding in this embodiment, such as the production equipment of pulp molding described above, includes the following steps: S101: First, prepare a sufficient amount of waste paper materials, classify the waste paper materials, remove impurities such as incompatible materials like plastics and metals. After preliminary treatment, send the qualified raw materials to the opening position at the top of the gear pair roller type crusher 4; S102: After the raw materials are prepared, the staff starts the in - line slurry mixing assembly 8 to work. The rotary power of the in - line slurry mixing assembly 8 is transmitted to each cam - type dynamic turbulent slurry mixing assembly 10 through the three - zone gear transmission structure 9. And one of the cam - type dynamic turbulent slurry mixing assemblies 10 drives the gear pair roller mill 4 to operate by using the bevel gear drive 11. At this time, the crushing rollers of the gear pair roller mill 4 apply pressure to the paper material and crush it into small pieces of paper. The crushed paper pieces smoothly enter the material guiding box 5 and the pulping tank 1 through the conical feeding cylinder 3; S103: Once the paper material is crushed and enters the pulping tank 1, the in - line slurry mixing assembly 8 continuously stirs the paper material and water to make them fully mixed to form a slurry. During the mixing process, the rotary power of the in - line slurry mixing assembly 8 is transmitted to the cam - type dynamic turbulent slurry mixing assembly 10 through the three - zone gear transmission structure 9. The cam - type dynamic turbulent slurry mixing assembly 10 generates a turbulent effect, enhancing the fluidity and uniformity of the slurry; S104: When the slurry is prepared, the slurry is discharged from the pulping tank 1. After discharging, the slurry is sent to the subsequent forming equipment for processing.
[0020] Embodiment 2, on the basis of Embodiment 1, is given by Figure 6 On the outer wall of one side of the pulping tank 1, a charging manhole 2 is installed. The charging manhole 2 facilitates the staff to add auxiliary materials and auxiliary liquids. And on the outer wall of the pulping tank 1 below the charging manhole 2, a slurry discharge pipe 6 is installed. One end of the slurry discharge pipe 6 away from the pulping tank 1 is equipped with a switching valve. A switching valve is installed at the end of the slurry discharge pipe 6 to achieve the purpose of controlling the discharge of the slurry; On one side of the bottom end of the material guiding box 5, a material pipe 501 is installed. The bottom end of the material pipe 501 penetrates through the outside of the partition disk 7 and extends into the inside of the pulping tank 1. The extension line of the central axis of the material pipe 501 is perpendicular to the extension line of the central axis of the charging manhole 2. The paper material crushed by the gear pair roller mill 4 enters the material guiding box 5 through the conical feeding cylinder 3 and continues to enter the pulping tank 1 through the material pipe 501. Through the settings of the material guiding box 5 and the material pipe 501, the crushed paper material can smoothly enter the pulping tank 1 without hindering the structural settings and smooth operation of the in - line slurry mixing assembly 8, the three - zone gear transmission structure 9, and the cam - type dynamic turbulent slurry mixing assembly 10.
[0021] Embodiment 3, on the basis of Embodiment 2, is given by Figure 5 、 Figure 7 and Figure 8Given that, the central slurry mixing assembly 8 is composed of a reduction motor 801, a central shaft 802, and a cage column type stirrer 803. The reduction motor 801 is installed on the outer wall of one side of the material guiding box 5. The central shaft 802 is rotatably installed at the central position inside the partition plate 7. The cage column type stirrer 803 is fixed at the bottom end of the central shaft 802. The top end of the central shaft 802 is fixedly connected to the bottom end of the output shaft of the reduction motor 801 through a coupling; The cage column type stirrer 803 includes circular steel plates fixed at both ends of the surface of the central shaft 802 and a number of annularly equally spaced C-shaped steel bars welded and fixed between the two circular steel plates. When the central slurry mixing assembly 8 is working, the output shaft of the reduction motor 801 drives the central shaft 802 and the cage column type stirrer 803 to rotate in sequence. The central shaft 802 is used to mix the slurry and the shredded paper material. The reduction motor 801 can provide a relatively high torque to ensure that the cage column type stirrer 803 can still maintain a stable stirring effect when dealing with high-viscosity slurry. And during the stirring process, the cage column type stirrer 803 can effectively prevent the solid particles in the slurry from precipitating, maintain the stability of the slurry, and ensure the smooth progress of the subsequent processes; The three-zone gear transmission structure 9 includes a central gear disk 901 fixed at one end of the surface of the central shaft 802 and a number of annularly equally spaced driven gear disks 902 rotatably installed at the edge position of the top end of the partition plate 7. The driven gear disks 902 are meshed with the central gear disk 901. The bottom end of the central gear disk 901 is rotatably connected to the top end of the partition plate 7. The driven gear disks 902 are connected to the cam type dynamic turbulent slurry mixing assembly 10; The driven gears 902 and the cam-type dynamic turbulent pulp mixing assemblies 10 are both provided in three numbers. The cam-type dynamic turbulent pulp mixing assembly 10 includes a T-shaped shaft seat 1001 fixed inside the partition disc 7, a driven shaft 1002 rotatably installed inside the T-shaped shaft seat 1001, a disc cam 1003 fixed to the bottom end of the driven shaft 1002, and a C-shaped vertical frame 1004 hingedly installed at the bottom end of the T-shaped shaft seat 1001. The driven shaft 1002 and the driven gear 902 are connected through a keyway. One side of the top end of the C-shaped vertical frame 1004 is rotatably installed with a roller 1005, and the roller 1005 is located in the groove of the disc cam 1003. A pointed orifice material distributing plate 1006 is fixed on the outer wall of one side of the C-shaped vertical frame 1004. The top end of one of the driven shafts 1002 penetrates to the outside of the pulp making tank 1 and drives the gear pair roll crusher 4 to work through a bevel gear drive 11. During the rotation of the output shaft of the reduction motor 801, the central gear disc 901 will be driven to rotate. Then, the central gear disc 901 drives the driven shaft 1002 and the disc cam 1003 to rotate through the driven gear 902. Since the roller 1005 is located in the groove of the disc cam 1003, the rotational motion of the disc cam 1003 is converted into the reciprocating swinging motion of the C-shaped vertical frame 1004 and the pointed orifice material distributing plate 1006 through the groove and the roller 1005. That is, during the process of the central shaft 802 rotating and mixing the liquid, the pointed orifice material distributing plate 1006 generates strong reciprocating turbulence to promote the full mixing of the slurry; The bevel gear drive 11 includes a U-shaped shaft frame 1101 fixed to one side of the top end of the pulp making tank 1, a horizontal shaft 1102 rotatably installed inside the U-shaped shaft frame 1101, and bevel gears 1103 installed at the relative end parts of the horizontal shaft 1102 and the straight bevel gears 1103. The two straight bevel gears 1103 mesh with each other. The other end of the horizontal shaft 1102 is fixedly connected to the end of one of the crushing rollers of the gear pair roll crusher 4. Since the end of one of the driven shafts 1002 penetrates to the outside of the pulp making tank 1 and drives the horizontal shaft 1102 to rotate through the straight bevel gear 1103, the horizontal shaft 1102 drives one of the crushing rollers of the gear pair roll crusher 4 to rotate, enabling the gear pair roll crusher 4 to work properly. In this way, multiple functions are integrated into one power system, and this design realizes the compactness of the structure and reduces the usage amount of motor equipment.
[0022] Before the pulping operation of pulp molding in the embodiments of the present application, the staff first need to prepare a sufficient amount of waste paper materials. The staff should classify the waste paper materials and remove impurities such as incompatible materials like plastics and metals. After preliminary treatment, the qualified raw materials are sent to the top opening position of the gear pair roller type crusher 4 to ensure the uniformity and appropriate humidity of the materials for subsequent crushing and mixing processes. When the raw materials are ready, the staff start the central mixing pulp assembly 8 to work. The rotary power of the central mixing pulp assembly 8 is transmitted to each cam type dynamic turbulent mixing pulp assembly 10 through the three-zone gear transmission structure 9. And one of the cam type dynamic turbulent mixing pulp assemblies 10 drives the gear pair roller type crusher 4 to operate by using the bevel gear transmission 11. At this time, the crushing rollers of the gear pair roller type crusher 4 apply pressure to the paper materials and crush them into small paper scraps. The crushed paper scraps smoothly enter the material guiding box 5 through the conical feeding tube 3 to ensure that the crushed paper scrap materials evenly flow into the pulping tank 1. During the crushing process, the staff need to regularly check the working state of the gear pair roller type crusher 4 to ensure its normal operation and avoid production stagnation caused by blockage or failure. Once the paper materials are crushed and enter the pulping tank 1, the central mixing pulp assembly 8 continuously stirs the paper materials and water to make them fully mixed to form a slurry. The staff need to adjust the water addition amount in a timely manner according to the viscosity and uniformity of the slurry to ensure that the slurry reaches the ideal concentration. During the mixing process, the rotary power of the central mixing pulp assembly 8 is transmitted to the cam type dynamic turbulent mixing pulp assembly 10 through the three-zone gear transmission structure 9. The three-zone gear transmission structure 9 conducts efficient power transmission. The staff can optimize the mixing effect of the slurry by adjusting the rotation speed of the central mixing pulp assembly 8 to ensure that the fibers in the slurry are evenly dispersed and avoid aggregation. In this process, the cam type dynamic turbulent mixing pulp assembly 10 generates an effective turbulent effect to enhance the fluidity and uniformity of the slurry. The staff need to observe the mixing effect to ensure good fluidity of the slurry and avoid slurry quality problems caused by uneven mixing. If necessary, the staff can adjust the rotation speed of the central mixing pulp assembly 8 to improve the mixing efficiency and quality. When the slurry is prepared, the staff use the discharge pipe 6 to discharge the slurry from the pulping tank 1. After discharging, the slurry will be sent to the subsequent forming equipment for processing. After completing the pulping operation, the staff need to comprehensively clean and maintain all components of the equipment, especially key equipment such as the gear pair roller type crusher, the material guiding box, and the mixing pulp assembly. Residual materials should be removed, the wear condition of the equipment should be checked, and necessary lubrication and maintenance should be carried out to ensure the smooth progress of the next production.

The rotational power of the central mixing assembly (8) is transmitted to each cam-type dynamic turbulent mixing assembly (10) through the three-zone gear transmission structure (9), and one of the cam-type dynamic turbulent mixing assemblies (10) drives the gear-pair roller type crusher (4) to operate using a bevel gear transmission (11). At this time, the crushing roller of the gear-pair roller type crusher (4) applies pressure to the paper material and crushes it into fine paper scraps. The crushed paper scraps smoothly enter the material guide box (5) and the pulping tank (1) through the conical feeding cylinder (3); S103: Once the paper stock is crushed and enters the pulping tank (1), the central mixing assembly (8) continuously stirs the paper stock and water to fully mix them to form a slurry. During the mixing process, the rotational power of the central mixing assembly (8) is transmitted to the cam-type dynamic turbulent mixing assembly (10) through the three-zone gear transmission structure (9). The cam-type dynamic turbulent mixing assembly (10) generates a turbulent effect to enhance the fluidity and uniformity of the slurry. S104: After the slurry is prepared, the slurry is discharged from the slurry tank (1) and sent to subsequent molding equipment for processing.
