[0002] In the paper manufacturing industry, the refiner is a crucial piece of production equipment, responsible for grinding raw materials (such as wood fiber and waste paper) into a pulp to facilitate subsequent papermaking processes. However, traditional refiner designs have some inherent problems that limit their performance improvement and the expansion of their application range.

[0003] In traditional pulp refiners, the grinding disc assembly is typically fixed inside the pulping housing, and the spacing between the discs cannot be flexibly adjusted according to the properties of the raw materials or the needs of pulping. This fixed disc configuration makes it difficult to achieve optimal pulping results for different types of raw materials. Furthermore, disc replacement and maintenance are relatively complex, increasing production and time costs. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the traditional pulping machine grinding disc assembly, which is fixedly installed, has an adjustable spacing, is difficult to adapt to different raw materials, and has complicated grinding disc replacement and maintenance, increasing costs. This invention aims to realize an outer cutter disc feeding structure for a paper pulping machine.

[0005] To achieve the above-mentioned objectives, the technical solution of this utility model is: an outer blade feed structure for a paper refiner, comprising a cover plate rotatably connected to the side wall of the refiner shell, and a feed mechanism connected to the side wall of the cover plate away from the refiner shell.

[0006] The inner sides of both the grinding pad and the cover plate are detachably connected to connecting discs. Each connecting disc is fixed with a set of grinding discs. Each set of grinding discs is arranged in a circumferential manner to form a grinding disc assembly, and the grinding discs in the two sets are located in the same plane and are adjacent to each other.

[0007] In the outer blade feed structure of the paper refiner described above, the connecting plate is provided with a snap-fit ​​groove for each grinding disc to snap into, and each grinding disc is fixed to the side wall of the connecting plate by bolts.

[0008] In the outer cutter head feeding structure of the aforementioned paper refiner, one of the connecting discs is slidably disposed on the inner side of the cover plate, and the inner side of the cover plate is provided with a groove for the sliding of the connecting disc.

[0009] In the outer cutter head feeding structure of the paper refiner described above, the side walls of the refinement shell and the cover plate are connected by hinges, and the side walls of the refinement shell and the cover plate are rotatably connected by the hinges.

[0010] In the outer cutter head feeding structure of the paper pulping machine described above, the top of the pulping shell is connected to a feed cylinder, the bottom of the pulping shell is connected to a discharge funnel, and the side wall of the pulping shell is rotatably connected to a fixing member for limiting and fixing the cover plate.

[0011] In the aforementioned outer cutter head feeding structure of the paper refiner, the feeding mechanism includes a rotating disk, a transmission rod, a drive motor, a driven gear, a connecting column, a slide rail, and a support column. The two rotating disks are rotatably connected to the side wall of the cover plate, and the two driven gears are respectively fixed to the opposite side walls of the two rotating disks. The transmission rod is rotatably connected to the side wall of the cover plate, and drive gears are fixed at both ends of the outer surface of the transmission rod, with each drive gear meshing with a driven gear. The drive motor is fixed to the side wall of the cover plate, and the output end of the drive motor is fixed to one end of the transmission rod.

[0012] In the outer cutter head feeding structure of the paper pulping machine described above, one end of each of the four slide rails is fixed to the side wall of the cover plate, and the four sides of the connecting column are respectively fixed with sliding plates for sliding on the slide rails; support columns are fixed on both sides of the connecting column, and a C-shaped groove is opened on the rotating disk, and the support column extends into the interior of the C-shaped groove and rotates inside it.

[0028] The outer cutter head feed structure of the paper pulping machine of this utility model will be described in more detail below with reference to the accompanying drawings and specific embodiments.

[0029] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] This embodiment discloses an outer cutter head feed structure for a paper refiner, referring to... Figure 1-7 The main components include a cover plate 4 rotatably connected to the side wall of the grinding shell 2, and a feeding mechanism 6 connected to the side wall of the cover plate 4 away from the grinding shell 2. Both the grinding shell 2 and the cover plate 4 are detachably connected to connecting discs 9. Each connecting disc 9 is fixed with a set of grinding discs 11. Each set of grinding discs 11 is arranged in a circumferential manner to form a grinding disc assembly, and the grinding discs 11 in the two sets are located in the same plane and are adjacent to each other.

[0031] The grinding shell 2 serves as the main structure, and a cover plate 4 is rotatably connected to its side wall. The cover plate 4 can rotate around the side wall of the grinding shell 2, thereby facilitating the opening or closing of the grinding area. A feeding mechanism 6 is connected to the side wall of the cover plate 4 away from the grinding shell 2. The feeding mechanism 6 is responsible for stably feeding the raw material into the grinding area, ensuring the continuity and stability of the grinding process.

[0032] Both the inner sides of the grinding shell 2 and the cover plate 4 are detachably connected to connecting discs 9, a design that allows for easy installation and removal of the grinding disc 11 assembly. Each connecting disc 9 has a set of grinding discs 11 fixed to it, and each set of grinding discs 11 is arranged in a circumferential pattern to form a grinding disc 11 assembly. This circumferential arrangement not only makes the spacing between the grinding discs 11 more uniform but also improves the uniformity and efficiency of the grinding process. Simultaneously, the grinding discs 11 on both sets of grinding disc 11 assemblies are located in the same plane and are adjacent to each other, ensuring that the raw material receives sufficient grinding action during the grinding process.

[0033] Reference Figure 1 and Figure 2 The connecting plate 9 has a snap-fit ​​groove for each grinding disc 11 to engage, and each grinding disc 11 is fixed to the side wall of the connecting plate 9 by bolts. One of the connecting plates 9 is slidably disposed inside the cover plate 4, and the inner side of the cover plate 4 has a sliding groove for the connecting plate 9 to slide. The side walls of the grinding shell 2 and the cover plate 4 are connected by a hinge 5, and the side walls of the grinding shell 2 and the cover plate 4 are rotatably connected by the hinge 5. The top of the grinding shell 2 is connected to the feed cylinder 3, the bottom of the grinding shell 2 is connected to the discharge funnel 8, and the side wall of the grinding shell 2 is rotatably connected to a fixing member 7 for limiting and fixing the cover plate 4.

[0034] The grinding housing 2 serves as the main structure, with internal space for mounting the grinding disc assembly. A snap-fit ​​groove is formed on the connecting plate 9 to secure each grinding disc 11. The grinding discs 11 are firmly mounted to the side wall of the connecting plate 9 with bolts, ensuring stability during the grinding process. One of the connecting discs 9 is slidably positioned inside the cover plate 4, and a groove is formed on the inner side of the cover plate 4 to provide a smooth track for the sliding of the connecting disc 9.

[0035] The cover plate 4 and the grinding shell 2 are rotatably connected by a hinge 5, which allows the cover plate 4 to be easily opened or closed, facilitating the installation, disassembly, and maintenance of the grinding disc assembly. In addition, the top of the grinding shell 2 is connected to a feed cylinder 3, which is used to stably feed the raw materials into the grinding area; the bottom is connected to a discharge funnel 8, which ensures that the ground material can be smoothly discharged.

[0036] To secure the cover plate 4, the grinding shell 2, and the side wall of the cover plate 4, a fastener 7 is also connected. When the cover plate 4 is closed in place, it can be firmly fixed by the fastener 7 to ensure the safety and stability of the grinding process.

[0037] Reference Figure 1-7 The feeding mechanism 6 includes a rotating disk 601, a transmission rod 603, a drive motor 604, a driven gear 605, a connecting column 606, a slide rail 608, and a support column 609. Two rotating disks 601 are rotatably connected to the side walls of the cover plate 4, and two driven gears 605 are respectively fixed to the opposite side walls of the two rotating disks 601. The transmission rod 603 is rotatably connected to the side walls of the cover plate 4, and drive gears 602 are fixed at both ends of the outer surface of the transmission rod 603. Each drive gear 602 meshes with a driven gear 605. The drive motor 604 is fixed to the side walls of the cover plate 4, and the output end of the drive motor 604 is fixed to one end of the transmission rod 603. One end of each of the four slide rails 608 is fixed to the side wall of the cover plate 4. Each of the four sides of the connecting column 606 is fixed with a sliding plate 607 for sliding on the slide rail 608. Support columns 609 are fixed on both sides of the connecting column 606. A C-shaped groove 6010 is provided on the rotating disk 601. The support column 609 extends into the C-shaped groove 6010 and rotates inside it.

[0038] Two rotating disks 601 are rotatably connected to the side wall of the cover plate 4, and two driven gears 605 are fixed on their opposite side walls. A transmission rod 603 is also rotatably connected to the side wall of the cover plate 4, with drive gears 602 fixed at both ends of its outer surface. Each drive gear 602 meshes with a corresponding driven gear 605. Thus, when the drive motor 604 starts, its output drives the transmission rod 603 to rotate, which in turn drives the two rotating disks 601 to rotate synchronously through the meshing of the drive gears 602 and driven gears 605.

[0039] One end of each of the four slide rails 608 is firmly fixed to the side wall of the cover plate 4, providing stable support for the sliding of the slide plate 607. Slide plates 607 are fixed to the four sides of the connecting column 606 respectively. These slide plates 607 can slide smoothly on the slide rails 608, ensuring the stability of the raw material during the feeding process.

[0040] Supporting columns 609 are fixed on both sides of the connecting column 606. These supporting columns 609 extend into the C-shaped groove 6010 opened on the rotating disk 601 and rotate within it. When the rotating disk 601 rotates, the contour of the C-shaped groove 6010 pushes the supporting columns 609 to rotate within the groove, thereby causing the connecting column 606 and the sliding plate 607 to slide along a specific trajectory on the slide rail 608.

[0041] Reference Figure 1-4 The side wall of the grinding shell 2 is connected to a drive mechanism 1, and the output end of the drive mechanism 1 is connected to the connecting plate 9 inside the grinding shell 2. The side wall of the connecting plate 9 inside the cover plate 4 is fixed with a plug post 10. One end of the connecting post 606 is provided with a groove for the plug post 10 to be inserted, and the plug post 10 is fixed inside the connecting post 606 by bolts.

[0042] The side wall of the grinding shell 2 is connected to the drive mechanism 1. The drive mechanism 1 serves as the power source for the grinder, and its output end is connected to the connecting disc 9 inside the grinding shell 2 via a transmission mechanism. This not only ensures the stable transmission of driving force but also allows the connecting disc 9 to rotate with the drive mechanism, thereby driving the grinding disc assembly to perform grinding operations.

[0043] Inside the cover plate 4, a plug-in post 10 is fixed to the side wall of the connecting plate 9. The design of the plug-in post 10 allows the connecting plate 9 to achieve a stable connection with the feed mechanism 6. Specifically, one end of the connecting post 606 has a groove for the plug-in post 10 to be inserted. This groove and plug-in post 10 mating method is both simple and effective, ensuring a firm and reliable connection between the connecting plate 9 and the feed mechanism 6. In addition, the plug-in post 10 is fixed inside the connecting post 606 by bolts, further enhancing the stability and durability of the connection.

[0044] The working principle of the outer blade feed structure of the paper pulping machine of this utility model is as follows: When using this device, the cover plate 4 is rotated to the side wall of the pulping shell 2, and then the fixing part 7 is rotated to limit and fix the cover plate 4. First, the drive mechanism 1 is started. The drive mechanism 1 drives the connecting plate 9 and the grinding disc 11 inside the pulping shell 2 to rotate. Then, the material is added into the inside of the pulping shell 2 through the feed cylinder 3. The two sets of grinding discs 11 cooperate to grind the material.

[0045] When grinding different materials, it is necessary to adjust the distance between the two sets of grinding discs 11. Start the drive motor 604. The output end of the drive motor 604 drives the transmission rod 603 to rotate. The two drive gears 602 on the transmission rod 603 drive the driven gear 605 to rotate. The driven gear 605 drives the rotating disk 601 to rotate. The C-shaped groove 6010 of the rotating disk 601 pushes the support column 609 to rotate. The support column 609 drives the connecting column 606 and the slide plate 607 to slide on the slide rail 608. The transmission rod 603 drives the connecting plate 9 inside the cover plate 4 to move, thereby adjusting the distance between the two grinding discs 11.
