Description

Technical Field

[0001] This application relates to the field of pulp molding technology, and more specifically, to a pulp molding machine. Background Technology

[0002] Currently, in the manufacturing and application of pulp molding machines, the lifting frame plays a crucial role. Through a combination of four guide rods, a lifting frame, a lower molding die, and linear bearings, it achieves precise lifting and positioning of the pulp mold. The guide rods, as the core component of the lifting frame, typically employ a stepped shaft design, characterized by a larger middle section and smaller ends. This structure aims to increase strength while reducing installation space. The lifting frame is equipped with holes that match the small-diameter section of the guide rods, allowing the guide rods to pass through and be fixed in designated positions. Linear bearings are fixed at the connection between the guide rods and the lifting frame or the lower molding die, ensuring the lifting frame remains stable and reduces friction during vertical movement. This design enables pulp molding machines to efficiently complete the molding and demolding of pulp molds during the manufacturing process and is currently the standard configuration in the industry.

[0003] However, while this design meets the operational requirements of pulp molding machines to a certain extent, some significant technical problems exist in actual use and maintenance. The most prominent issue is the extreme inconvenience of replacing and maintaining linear bearings. When replacing linear bearings, due to the limitations of their installation location, it is often necessary to disassemble the lifting frame first. This process is not only time-consuming and labor-intensive but also severely impacts production efficiency. Especially in some cases, linear bearing replacement needs to be performed below the lower molding die. Due to extremely limited operating space and the presence of the pulp trough, the difficulty and complexity of disassembly are increased. This not only prolongs maintenance time but may also damage other components due to improper operation. Utility Model Content

[0004] The main objective of this application is to provide a pulp molding machine to solve the technical problem of inconvenient disassembly and repair of existing pulp molding machines.

[0005] To achieve the above objectives, according to one aspect of this application, a pulp molding machine is provided, comprising a base and a linear bearing, the linear bearing being fixedly mounted on the base; a guide rod and a lower mold, the guide rod being detachably mounted on the base, extending vertically and movably passing through the linear bearing, the lower mold being fixedly mounted on a first end of the guide rod; a lifting frame having a first engaging portion, the second end of the guide rod being detachably mounted through the first engaging portion, the first engaging portion having a communicating opening, the width of the communicating opening being greater than or equal to the diameter of the second end of the guide rod, so that the guide rod can be mounted to the lifting frame through the communicating opening.

[0006] Furthermore, the pulp molding machine also includes a first connecting member, which includes a sleeve portion and a flange. The sleeve portion is fitted onto the guide rod, and the flange is disposed on the sleeve portion. The flange is detachably connected to the lifting frame. The inner diameter of the sleeve portion is equal to the outer diameter of the second end of the guide rod.

[0007] Furthermore, the first snap-fit ​​part is also provided with a positioning hole, which is connected to the connecting opening. At least a portion of the sleeve part is disposed in the positioning hole so that the guide rod passes through the positioning hole. The outer diameter of the sleeve part is equal to the inner diameter of the positioning hole.

[0008] Furthermore, the flange is located at the end of the sleeve portion away from the base, and the distance between the lower end face of the flange and the upper end face of the lifting frame is adjustable.

[0009] Furthermore, the pulp molding machine also includes a second connector. The second end of the guide rod is provided with a first threaded structure. The guide rod extends at least partially out of the positioning hole. The second connector is sleeved on the guide rod and is located on the side of the flange away from the base. The second connector is provided with a second threaded structure. The first threaded structure and the second threaded structure are threadedly engaged so that the guide rod is detachably connected to the lifting frame through the second connector.

[0010] Furthermore, the pulp molding machine also includes a mounting frame, at least a portion of which is disposed between a first end and a second end of the guide rod. The mounting frame is provided with a second locking part, and at least a portion of the guide rod is locked onto the second locking part; wherein at least a portion of the linear bearing is connected to the mounting frame.

[0011] Furthermore, the second snap-fit ​​part is provided with an installation port, which is set away from the mounting bracket. The orientation of the installation port is the same as that of the connecting opening. The width of the installation port is equal to the width of the guide rod. The guide rod is snapped onto the second snap-fit ​​part through the installation port.

[0012] Furthermore, the pulp molding machine also includes a third connector. The first end of the guide rod is provided with a mounting part, which includes a mounting hole and a clearance channel. The mounting hole is provided on the first end of the guide rod along the axial direction. The third connector passes through the mounting hole and extends at least partially out of the mounting hole to connect with the lower mold. The clearance channel is provided on one side of the mounting hole and is used to connect the mounting hole with the space outside the guide rod.

[0013] Furthermore, the first end of the guide rod is provided with a mounting platform, which is mounted on the base. At least a portion of the third connector passes through the mounting platform and is connected to the lower mold. The end face of the mounting platform on the side away from the lower mold is set higher than the upper end face of the lower mold, or the end face of the mounting platform on the side away from the lower mold is flush with the upper end face of the lower mold. At least a portion of the end face of the third connector on the side away from the lower mold extends out of the end face of the mounting platform.

[0014] Furthermore, clearance channels are provided on both sides of the mounting hole; wherein, the length of the mounting hole along the axial direction of the guide rod is greater than or equal to the length of the clearance channel along the axial direction of the guide rod; and / or, the length of the clearance channel along the axial direction of the guide rod is equal to the length of the third connector along the axial direction of the guide rod; and / or, the cross-sectional area of ​​the clearance channel at the end closer to the base is greater than the cross-sectional area of ​​the clearance channel at the end farther from the base.

[0015] By applying the technical solution of this application, a connecting opening is added to the first snap-fit ​​portion of the lifting frame, cleverly altering the installation and disassembly path of the guide rod, thus enabling radial assembly of the guide rod. Since the width of the connecting opening is designed to be greater than or equal to the diameter of the second end of the guide rod, this ensures that the guide rod can smoothly connect to the lifting frame through the opening without compromising the integrity of the original structure. This application, by setting a matching width connecting opening in the first snap-fit ​​portion of the lifting frame, in conjunction with the special design of the guide rod, achieves radial installation and disassembly of the guide rod without disassembling the entire lifting frame, thereby solving the problem of inconvenient disassembly and repair caused by linear bearing replacement in the prior art.

Detailed Implementation

[0028] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] Please refer to Figures 1-9 This application provides a pulp molding machine, including a base 100 and a linear bearing 700, the linear bearing 700 being fixedly mounted on the base 100; a guide rod 200 and a lower mold 900, the guide rod 200 being detachably mounted on the base 100, the guide rod 200 extending vertically and movably passing through the linear bearing 700, and the lower mold 900 being fixedly mounted on the first end of the guide rod 200; a first snap-fit ​​portion is provided on a lifting frame 300, the second end of the guide rod 200 being detachably mounted through the first snap-fit ​​portion, the first snap-fit ​​portion being provided with a connecting opening, the width of the connecting opening being greater than or equal to the diameter of the second end of the guide rod 200, so that the guide rod 200 can be installed on the lifting frame 300 through the connecting opening.

[0030] The pulp molding machine provided in this application embodiment, by setting a matching width connecting opening in the first snap-fit ​​part of the lifting frame 300, works in conjunction with the special design of the guide rod 200 to realize the radial installation and disassembly of the guide rod 200 without disassembling the entire lifting frame 300, thereby solving the technical problem of inconvenient disassembly and repair caused by the replacement of the linear bearing 700 in the prior art.

[0031] In the above embodiments, such as Figures 1 to 3 As shown, the embodiments of this application propose an innovative design for a pulp molding machine. The core of this design lies in optimizing the connection mechanism between the guide rod 200 and the lifting frame 300, thereby significantly improving the maintainability and ease of operation of the equipment. In traditional designs, replacing the linear bearing 700 usually involves a complex and time-consuming disassembly process of the lifting frame 300, which not only increases the workload of equipment maintenance but also prolongs downtime, negatively impacting production efficiency. To address this technical bottleneck, this application cleverly alters the installation and disassembly path of the guide rod 200 by adding a connecting opening to the first snap-fit ​​portion of the lifting frame 300, making radial assembly of the guide rod 200 possible. Since the width of the connecting opening is designed to be greater than or equal to the diameter of the second end of the guide rod 200, this ensures that the guide rod 200 can smoothly connect to the lifting frame 300 through the opening without compromising the integrity of the original structure.

[0032] The benefits of this technological improvement are multifaceted. First, the radial assembly path significantly simplifies the replacement process of the linear bearing 700. Maintenance personnel can remove and install the guide rod 200 without completely disassembling the lifting frame 300. This not only shortens the maintenance cycle and reduces unnecessary labor intensity but also avoids potential structural damage caused by frequent disassembly and reassembly of the lifting frame 300, enhancing the overall stability of the equipment. Second, this separate design of the guide rod 200 and the lifting frame 300 allows maintenance personnel to work in a larger operating space, overcoming the challenges posed by the confined operating environment in traditional designs and improving operational safety and accuracy. Furthermore, the detachable design further enhances the flexibility of the equipment. When it is necessary to replace the linear bearing 700 or the worn guide rod 200, the process can be completed more quickly and easily, effectively promoting increased production efficiency.

[0033] Specifically, the pulp molding machine also includes a first connecting member 400, which includes a sleeve portion 410 and a flange 420. The sleeve portion 410 is sleeved on the guide rod 200, and the flange 420 is disposed on the sleeve portion 410. The flange 420 is detachably connected to the lifting frame 300. The inner diameter of the sleeve portion 410 is equal to the outer diameter of the second end of the guide rod 200. This application introduces a first connecting member 400, which consists of a sleeve portion 410 and a flange 420, to further optimize the connection mechanism between the guide rod 200 and the lifting frame 300, thereby achieving more efficient and simpler equipment maintenance. In traditional pulp molding machines, the connection between the guide rod 200 and the lifting frame 300 often relies on direct threaded connections or similar fixing methods. This leads to the complete disassembly of the lifting frame 300 when components such as the linear bearing 700 need to be replaced, which is not only cumbersome but also prone to causing additional damage to other components of the equipment. To solve this problem, this application creatively designs the first connector 400 as a sleeve portion 410 that fits tightly with the guide rod 200 and a flange 420 that can be detachably connected to the lifting frame 300. By using specific dimensional matching—the inner diameter of the sleeve portion 410 is equal to the outer diameter of the second end of the guide rod 200—a quick and stable connection and separation between the guide rod 200 and the lifting frame 300 is achieved.

[0034] First, such as Figure 4 , Figure 5 As shown, the precise dimensional matching of the sleeve portion 410 and flange 420 in the first connecting member 400 ensures stable sliding of the guide rod 200 on the linear bearing 700. Simultaneously, the detachable connection between the flange 420 and the lifting frame 300 eliminates the disassembly and assembly difficulties associated with traditional direct connections. Secondly, the tight fit design between the sleeve portion 410 and the guide rod 200 ensures that the guide rod 200 maintains good straightness and rigidity under external forces, thereby improving the molding accuracy and working efficiency of the pulp molding machine. Furthermore, the connection between the flange 420 and the lifting frame 300 is easily detachable. Combined with the unique design of the connecting opening, maintenance personnel can install and unload the guide rod 200 through radial operation without completely disassembling the lifting frame 300, greatly simplifying the replacement process of the linear bearing 700.

[0035] Specifically, such as Figure 3As shown, a positioning hole 320 is also provided on the first snap-fit ​​part. The positioning hole 320 communicates with the connecting opening. At least a portion of the sleeve part 410 is disposed within the positioning hole 320 so that the guide rod 200 passes through the positioning hole 320. The outer diameter of the sleeve part 410 is equal to the inner diameter of the positioning hole 320. In the design of the pulp molding machine of this application, by adding a positioning hole 320 to the first snap-fit ​​part and cleverly connecting the positioning hole 320 with the connecting opening, the connection mechanism between the guide rod 200 and the lifting frame 300 is further optimized, achieving a dual improvement in equipment performance and maintenance convenience. Specifically, the second end of the guide rod 200 is stably embedded in the positioning hole 320 by means of at least a portion of the sleeve part 410. This positioning method ensures the precise movement of the guide rod 200 in the vertical direction. At the same time, the tight fit between the sleeve part 410 and the positioning hole 320 effectively enhances the connection strength between the guide rod 200 and the lifting frame 300, ensuring the structural stability and operational accuracy of the equipment during operation. The mating of the positioning hole 320 and the connecting opening allows the guide rod 200 to be installed radially, rather than in the traditional axial assembly. Firstly, the radial assembly path greatly simplifies the replacement process of the linear bearing 700. Maintenance personnel can easily disassemble and install the guide rod 200 without following cumbersome steps to disassemble the lifting frame 300, significantly reducing downtime for maintenance and improving equipment production efficiency. Secondly, the positioning hole 320 provides a precise positioning reference for the guide rod 200, enabling quick alignment during installation, reducing operational errors caused by inaccurate positioning, and improving assembly accuracy. Furthermore, this design avoids the wear and loosening problems caused by long-term axial movement in traditional structures. The mating of the positioning hole 320 and the sleeve portion 410 effectively extends the service life of the guide rod 200 and reduces production costs.

[0036] Furthermore, from the perspective of operational safety and convenience, the design of the positioning hole 320 and the connecting opening provides a more user-friendly operating environment for maintenance personnel. The width of the connecting opening is greater than or equal to the diameter of the second end of the guide rod 200, ensuring that the guide rod 200 can be smoothly disassembled and installed through the opening when replacing the linear bearing 700, avoiding potential safety hazards caused by limited operating space. At the same time, the introduction of the positioning hole 320 makes the installation of the guide rod 200 more intuitive, reduces the difficulty of the assembly process, improves the work efficiency and safety of maintenance personnel, reduces unnecessary production interruptions, and provides a strong guarantee for the continuous and stable operation of the pulp molding machine.

[0037] When it is necessary to separate the guide rod and the lifting frame 300, first loosen the fastener on the sleeve part 410 of the first connector 400, slide the first connector 400 along the axial direction of the guide rod 200 so that the first connector 400 comes out of the positioning hole 320, and then move the guide rod 200 along the radial direction so that the guide rod 200 is pulled out from the communicating opening.

[0038] Specifically, the flange 420 is located at the end of the sleeve portion 410 away from the base 100, and the distance between the lower end face of the flange 420 and the upper end face of the lifting frame 300 is adjustable. In the traditional pulp molding machine structure, the fixed relationship between the guide rod 200 and the lifting frame 300 is often rigid, which causes many inconveniences when replacing the linear bearing 700 and adjusting the equipment, not only prolonging maintenance time but also potentially leading to a decline in equipment performance due to improper operation. However, this application achieves a more flexible and convenient connection between the guide rod 200 and the lifting frame 300 by assembling the flange 420 at the end of the sleeve portion 410 away from the base 100 and cleverly designing the distance between the lower end face of the flange 420 and the upper end face of the lifting frame 300 to be adjustable. This innovative design allows for easy removal and installation of the guide rod 200 during linear bearing 700 replacement without completely disassembling the lifting frame 300. Only the distance between the flange 420 (lower end face of the sleeve 410) and the lifting frame 300 needs to be adjusted, greatly simplifying the maintenance process, reducing equipment downtime, and thus improving production efficiency. Furthermore, the adjustable spacing design gives operators more autonomy in equipment debugging and precise positioning, allowing for rapid adjustment of the guide rod 200's position according to actual production needs.

[0039] Specifically, the pulp molding machine also includes a second connector 500. A first threaded structure is provided on the second end of the guide rod 200, and the guide rod 200 extends at least partially out of the positioning hole 320. The second connector 500 is sleeved on the guide rod 200 and is located on the side of the flange 420 away from the base 100. A second threaded structure is provided on the second connector 500. The first and second threaded structures are threadedly engaged, allowing the guide rod 200 to be detachably connected to the lifting frame 300 via the second connector 500. The threaded engagement between the second end of the guide rod 200 and the second threaded structure on the second connector 500 not only ensures a stable connection between the guide rod 200 and the lifting frame 300, but also allows for easy disassembly and assembly of the second connector 500 with the guide rod 200 through threaded engagement, thus avoiding the cumbersome steps of extensive disassembly of the lifting frame 300 required in traditional methods. The key to this design is that by placing the second connector 500 on the side of the flange 420 away from the base 100, maintenance personnel can adjust the threaded connection in a more spacious operating space without having to operate in a narrow or hard-to-reach location, which greatly improves maintenance efficiency and safety.

[0040] Furthermore, the threaded connection between the second connector 500 and the guide rod 200 provides greater flexibility during installation and adjustment. Since the guide rod 200 extends at least partially from the positioning hole 320, the second connector 500 can be adjusted axially along the guide rod 200, thereby fine-tuning the gap between the flange 420 and the lifting frame 300. This ensures precise fit between the various components of the equipment, improving the molding accuracy and product quality of the pulp molding machine. Simultaneously, this adjustable gap design can accommodate wear or deformation caused by prolonged operation, extending the equipment's service life and reducing maintenance frequency through timely adjustments.

[0041] Specifically, such as Figure 6As shown, the pulp molding machine also includes a mounting frame 600. At least a portion of the mounting frame 600 is disposed between the first end and the second end of the guide rod 200. The mounting frame 600 is provided with a second locking part, and at least a portion of the guide rod 200 is locked onto the second locking part. At least a portion of the linear bearing 700 is connected to the mounting frame 600. By locking a portion of the guide rod 200 within the second locking part, stable guidance and support of the guide rod 200 throughout its entire range of motion are ensured. Simultaneously, at least a portion of the linear bearing 700 is also designed to be directly connected to the mounting frame 600. This structural arrangement not only enhances the synergy between the linear bearing 700 and the guide rod 200 but also indirectly achieves effective docking between the linear bearing 700 and the lifting frame 300, the lower mold 900, and the base 100 through the mounting frame 600. Firstly, through the rationally designed mounting frame 600 and its second locking part, the maintenance efficiency of the equipment is significantly improved. When the linear bearing 700 needs replacement or inspection, maintenance personnel only need to handle the connection between the mounting bracket 600 and the guide rod 200, and the linear bearing 700, without the need for extensive disassembly of the lifting frame 300 or other components as in traditional machines. This significantly saves maintenance time and labor costs, and improves equipment operating efficiency and production continuity. Secondly, the presence of the mounting bracket 600 optimizes the internal spatial layout of the equipment. As an intermediate layer, it not only connects the guide rod 200 and the linear bearing 700, but also balances the stress on various parts of the equipment, reducing wear and failure rates caused by excessive load on a single component, thereby extending the service life of the entire system. Furthermore, this design effectively improves the processing accuracy of the pulp molding machine. As a bridge between the guide rod 200 and the linear bearing 700, the stability and positioning accuracy of the mounting bracket 600 directly affect the mold movement trajectory during the pulp molding process, thus determining the molding quality and consistency of the product. By employing a precise fit between the second snap-fit ​​part and the guide rod 200, and a stable connection between the linear bearing 700 and the mounting bracket 600, this application ensures high precision and high quality output during the pulp molding process.

[0042] Specifically, the second locking part is provided with a mounting port 610, which is positioned away from the mounting frame 600. The orientation of the mounting port 610 is the same as that of the connecting opening, and the width of the mounting port 610 is equal to the width of the guide rod 200. The guide rod 200 is locked onto the second locking part through the mounting port 610. In traditional equipment structures, the guide rod 200 is usually connected to the lifting frame 300 and the mounting frame 600 by direct axial penetration. Although this method can ensure the stability of equipment operation, it also has obvious drawbacks, especially in the replacement of the linear bearing 700 and the adjustment of the guide rod 200. The operation is complicated and limited by the narrow operating space, resulting in low maintenance efficiency and even the possibility of accidental damage to other components of the equipment. To solve this common industry problem, this application proposes an innovative design of opening a mounting port 610 on the second locking part. The mounting port 610 is positioned away from the mounting frame 600, and its orientation is consistent with that of the connecting opening. This means that the guide rod 200 can be radially locked onto the second locking part in the same direction without having to follow the traditional axial assembly path. In particular, the width of the mounting port 610 is carefully set to be equal to the width of the guide rod 200, ensuring that the guide rod 200 can accurately connect with the second snap-fit ​​part through the mounting port 610, which not only ensures the stability of the connection, but also avoids assembly difficulties caused by dimensional deviations.

[0043] First, the radial assembly path significantly simplifies the installation and disassembly process of the guide rod 200, especially for the replacement of the linear bearing 700. This avoids large-scale disassembly of the lifting frame 300 and mounting frame 600, reducing maintenance time and labor intensity, and improving equipment availability and production efficiency. Second, the consistent orientation of the mounting port 610 and the connecting opening ensures a smooth transition between different locking parts of the guide rod 200, preventing jamming or assembly errors caused by misalignment and improving the accuracy and smoothness of the assembly process. Third, the precise width matching makes the connection between the guide rod 200 and the second locking part tighter, reducing shaking and displacement during operation, and improving the stability and linear motion accuracy of the equipment. This is crucial for ensuring the quality of pulp molded products.

[0044] Specifically, such as Figures 7 to 9As shown, the pulp molding machine also includes a third connector 800. A mounting portion 210 is provided on the first end of the guide rod 200. The mounting portion 210 includes a mounting hole 211 and a clearance channel. The mounting hole 211 is located along the axial direction of the guide rod 200 on the first end of the guide rod 200. The third connector 800 passes through the mounting hole 211 and at least partially extends out of the mounting hole 211 to connect with the lower mold 900. The clearance channel is located on one side of the mounting hole 211 and connects the mounting hole 211 with the space outside the guide rod 200. Firstly, the clearance channel provides maintenance personnel with a direct visual and operational passage. Through this channel, the precise installation and disassembly of the third connector 800 can be achieved without disassembling or moving other large components, greatly simplifying the replacement process of key components such as the linear bearing 700, reducing equipment maintenance time, and ensuring production continuity and efficiency. Secondly, the tight fit between the mounting hole 211 and the third connector 800 ensures a stable connection between the guide rod 200 and the lower mold 900, avoiding equipment instability caused by loose connections and improving the working accuracy and product quality of the pulp molding machine.

[0045] Specifically, a mounting platform 220 is provided at the first end of the guide rod 200. The mounting platform 220 is mounted on the lower mold 900. At least a portion of the third connector 800 passes through the mounting platform 220 and is connected to the lower mold 900. The end face of the mounting platform 220 on the side away from the lower mold 900 is higher than the upper end face of the lower mold 900, or the end face of the mounting platform 220 on the side away from the lower mold 900 is flush with the upper end face of the lower mold 900. At least a portion of the end face of the third connector 800 on the side away from the lower mold 900 extends beyond the end face of the mounting platform 220. In the pulp molding machine design of this application, the combination of the mounting platform 220 and the third connector 800 is introduced regarding the connection structure between the guide rod 200 and the lower mold 900, aiming to provide a more stable and easier-to-maintain connection solution. Specifically, the mounting platform 220 is positioned at the first end of the guide rod 200. Through the third connector 800, not only is an effective connection achieved between the guide rod 200 and the lower mold 900, but the structural stability and operational accuracy of the entire device during operation are also ensured. Depending on the position of the end face of the mounting platform 220 relative to the upper end face of the lower mold 900, this design provides two implementation methods: First, when the end face of the mounting platform 220 is higher than the upper end face of the lower mold 900, the third connector 800 passes through the mounting platform 220 and extends further to the lower mold 900, forming a higher connection point. This design helps improve the overall rigidity of the device and can significantly reduce the bending and vibration of the guide rod 200. Another implementation is to set the end face of the mounting platform 220 flush with the upper end face of the lower mold 900. In this case, the end of the third connector 800 still partially protrudes from the end face of the mounting platform 220. This design focuses more on the rational use of the internal space of the equipment. Through the compact arrangement of components, the footprint of the equipment is reduced. At the same time, while ensuring the connection strength, it provides a more convenient radial operation path for the maintenance of key components such as the linear bearing 700, simplifies the maintenance process, and reduces maintenance costs.

[0046] The end portion of the third connector 800 extends out of the mounting platform 220, which maintains the reliability of the connection and provides the necessary space for the installation and disassembly of components. In particular, for the linear bearing 700 that needs to be replaced, maintenance personnel can operate directly above the equipment without extensive disassembly, effectively avoiding production interruptions caused by maintenance and improving the continuous operation capability of the equipment.

[0047] Specifically, clearance channels are provided on both sides of the mounting hole 211; wherein, the length of the mounting hole 211 along the axial direction of the guide rod 200 is greater than or equal to the length of the clearance channel along the axial direction of the guide rod 200; and / or, the length of the clearance channel along the axial direction of the guide rod 200 is equal to the length of the third connector 800 along the axial direction of the guide rod 200; and / or, the cross-sectional area of ​​the end of the clearance channel near the base 100 is greater than the cross-sectional area of ​​the end of the clearance channel away from the base 100.

[0048] First, the introduction of the clearance channel greatly simplifies the installation and disassembly process of the third connector 800. In traditional designs, the connection between the guide rod 200, the linear bearing 700, and the lifting frame 300 is tight and fixed. When replacing or maintaining the third connector 800, the operator must perform axial operations in a confined space, which not only increases the complexity of maintenance but may also damage other components of the equipment due to improper operation. However, this application, by setting clearance channels on both sides of the mounting hole 211, ensures that the length of the mounting hole 211 along the axial direction of the guide rod 200 is greater than or equal to the length of the clearance channel. This provides sufficient space for the radial movement of the third connector 800 on the guide rod 200. The operator can conveniently replace the third connector 800 through the clearance channel without completely disassembling the connection between the guide rod 200 and the lifting frame 300, significantly reducing equipment downtime and improving production efficiency.

[0049] Secondly, the length of the clearance channel along the axial direction of the guide rod 200 is equal to the length of the third connector 800, which allows for more precise control of the position when replacing the third connector 800, making it easier to place the third connector 800 into the mounting hole 211.

[0050] Furthermore, the change in the cross-sectional area of ​​the clearance passage makes it easier to insert a hex wrench into the clearance passage to tighten or loosen the third connecting piece 800.

[0051] Specifically, in the embodiments of this application, a pulp tank 110 is provided on the base 100. The pulp tank 110 is used to hold pulp slurry. The pulp molding machine is also provided with a lifting cylinder. The telescopic end of the lifting cylinder is connected to the upper end of the lifting frame 300 to drive the lifting frame 300, the four guide rails on the lifting frame 300, and the lower mold 900 fixedly connected below the guide rails to move vertically, so as to extend into the pulp tank 110 so that the lower mold 900 can hold pulp slurry or rise out of the pulp tank 110 to extract water from the pulp. The lower mold 900 is connected to a water pumping system through a hose to extract water from the pulp to form a wet pulp film for further processing.

[0052] As can be seen from the above description, the embodiments of this application achieve the following technical effects:

[0053] Improved maintenance convenience: By setting a connecting opening on the first snap-fit ​​part, the installation and disassembly path of the guide rod 200 is changed from the traditional axial path to the radial path, which greatly simplifies the connection between the guide rod 200 and the lifting frame 300, thereby significantly reducing the time and workload required to replace the linear bearing 700 and reducing production downtime and costs caused by maintenance.

[0054] Enhanced operational flexibility: The introduction of a first connector 400, including a sleeve portion 410 and a flange 420, not only ensures a stable connection between the guide rod 200 and the lifting frame 300, but also allows for fine-tuning of the equipment component gaps by adjusting the distance between the flange 420 and the upper end face of the lifting frame 300, thereby improving the operational flexibility of the equipment and the molding accuracy during the pulp molding process.

[0055] Optimize structural stability: A positioning hole 320 is provided in the first snap-fit ​​part, and at least part of the sleeve part 410 is placed in the positioning hole 320. This not only makes the positioning of the guide rod 200 on the lifting frame 300 more accurate, but also enhances the structural stability of the entire equipment, reduces shaking during operation, and improves product quality.

[0056] Improved equipment adjustability: The second connector 500 is threaded to the second end of the guide rod 200, allowing for quick assembly and disassembly of the connection between the guide rod 200 and the lifting frame 300. At the same time, by adjusting the position of the second connector 500, the distance between the upper mold and the lower mold 900 can be finely adjusted to meet the requirements of different pulp molding processes, thereby improving the adaptability and production efficiency of the equipment.

[0057] Simplify the replacement process of linear bearing 700: A mounting port 610 is provided in the second snap-fit ​​part, the width of which is equal to the width of the guide rod 200. This changes the assembly path of the guide rod 200 on the mounting bracket 600 to radial. While ensuring a stable connection, this significantly simplifies the replacement process of linear bearing 700, provides a more direct operation path, and reduces maintenance difficulty.

[0058] Enhanced installation flexibility of the third connector 800: A mounting part 210 is provided at the first end of the guide rod 200, including a mounting hole 211 and a clearance channel. This design allows the third connector 800 to move radially within the mounting hole 211, which facilitates connection on the base 100. It also provides additional operating space for the installation of the third connector 800, enhancing its ease of installation and flexibility.

[0059] Optimize the layout of the mounting platform 220 to improve structural efficiency: By adjusting the position of the mounting platform 220 relative to the base 100, it is ensured that the third connector 800 can extend partially or completely from the mounting platform 220. This not only optimizes the structural layout of the equipment, but also provides a more stable support point for the connection between the guide rod 200 and the base 100, thereby improving the operating efficiency and structural stability of the equipment.

[0060] More refined internal space management is provided: Clearance channels are provided on both sides of the mounting hole 211 to ensure their length matches the length of the third connector 800. This not only enhances the management of the equipment's internal space but also provides greater operational space and flexibility for the installation and disassembly of the third connector 800. Simultaneously, the change in the cross-sectional area of ​​the clearance channels disperses stress during installation, extending the equipment's lifespan. The above description is merely a preferred embodiment of this application and is not intended to limit the application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
