Description
Technical Field
[0001] This utility model relates to the field of pulp molding technology, and in particular to a pulp molding station linkage device. Background Technology
[0002] Pulp molding is an environmentally friendly manufacturing technology that uses plant fibers or waste paper as raw materials to create various three-dimensional products through processes such as pulping, molding, and drying. A pulp molding station refers to a specific location or functional unit on a pulp molding production line used to complete a specific production task. These stations work together to complete the entire process from raw pulp to finished pulp molded products.
[0003] Currently, in the traditional production process of pulp molding products, product translation between different workstations is mostly achieved through separate power transfer. While this traditional design approach can barely meet basic production needs and maintain the continuous operation of the production line in certain scenarios, it has many drawbacks that urgently need to be addressed from the perspective of overall production efficiency and cost control. Specifically, adopting a separate power transfer mode means that each step involving lifting and translation operations requires an independent power system. Taking the transfer of pulp molding products from the molding station to the drying station, and subsequently from the drying station to the shaping station, as an example, two sets of lifting and translation power devices need to be set up between these two key processes. These two sets of power devices not only contain complex components such as motors, transmission parts, and control systems, but also require customized development during the design and manufacturing process to meet the specific needs of each workstation. This undoubtedly greatly increases the complexity and cost of equipment manufacturing. Utility Model Content
[0004] The technical problem to be solved by this utility model is that in the production process of traditional pulp mold products, different work stations adopt separate power transfer methods, and each lifting and translation link needs to be equipped with an independent power device, which leads to complex equipment structure and high manufacturing cost.
[0005] To solve the above-mentioned technical problems, this utility model provides a pulp molding station linkage device, which includes a frame body, a lifting component, and a translation component. The frame body includes a base. The lifting component is disposed above the base and includes a lifting unit, a transmission coupling, and a first drive motor. The number of lifting units is at least two, and the two lifting units are arranged at intervals in the horizontal direction. The transmission coupling is disposed between the two lifting units. Each lifting unit is provided with a first connecting plate for connecting the translation component. One end of the transmission coupling is connected to the first drive motor. The first drive motor drives the transmission coupling, thereby driving the two first connecting plates to reciprocate in the vertical direction. The translation component includes a translation gear, a translation rack, and a second drive motor. The translation rack is arranged in the horizontal direction between the two first connecting plates. One end of the translation component is connected to a material picking tray assembly. The second drive motor is connected to the translation gear. The rotation of the translation gear drives the translation rack to move in the horizontal direction, thereby driving the material picking tray assembly to reciprocate in the horizontal direction.
[0006] In one embodiment, each lifting unit includes a fixed frame, a lifting guide rail, and a lifting screw. The fixed frame is disposed above the base, and the lifting guide rail and the lifting screw are disposed on one side of the fixed frame. There are two lifting guide rails, and the lifting screws are disposed on both sides of the lifting guide rails.
[0007] In one embodiment, the top end of the lifting screw is connected to the fixed frame, and the bottom end of the lifting screw is fixed to the base and connected to the transmission coupling. The lifting screw is used to convert the rotational motion of the transmission coupling into linear motion, thereby driving the connecting part on the lifting guide rail to reciprocate in the vertical direction.
[0008] In one embodiment, the translation component further includes two second connecting plates, which are fixedly connected to the first connecting plate. One end of one of the second connecting plates is connected to a second drive motor, and the other end is connected to a translation gear. The second drive motor passes through the second connecting plate and is connected to the translation gear, and the translation gear meshes with the translation rack.
[0009] In one embodiment, the translation rack is a linear guide structure with continuous tooth profiles on its surface. The translation gear drives the translation rack to move horizontally by rotation. A second drive motor is connected to the translation gear to provide rotational power.
[0010] In one embodiment, the translation component further includes a support frame disposed between the two lifting units. The support frame extends horizontally, and a translation rack is disposed above and connected to the support frame. The support frame is used to fix the translation rack and guide the translation rack to move horizontally.
[0011] In one embodiment, the number of material picking trays is the same as the number of translation gears, and each material picking tray includes a third connecting plate and multiple suction cups, with one end of the third connecting plate fixedly connected to the support frame.
[0012] In one embodiment, multiple suction cups are spaced apart at the bottom of the third connecting plate, and the suction cups are used to adsorb pulp molded products.
[0013] In one embodiment, there are two bases, and each base has multiple fasteners at its bottom. The fasteners are located at the four corners of the base and are used to fix the frame body.
[0014] In one embodiment, the frame body also includes adjusting bolts, the number of which is the same as the number of fasteners. The adjusting bolts are respectively located at the four corners of the base, and the adjusting bolts are located at one end of the fasteners. The adjusting bolts are detachably connected to the base.
[0015] Compared with the prior art, the beneficial effects of this embodiment of the pulp molding station linkage device are as follows: This device achieves a composite motion of vertical lifting and horizontal translation of the material handling tray group through the coordinated design of the lifting component and the translation component. The lifting component includes two lifting units, a transmission coupling, and a first drive motor. The two lifting units are mechanically linked through the transmission coupling and driven by a single first drive motor, ensuring synchronous movement at both ends during the lifting process. This avoids equipment tilting or uneven load caused by asynchronous movement, effectively reducing manufacturing costs. The translation component uses a rack and pinion drive, which has higher positioning accuracy and repeatability compared to belt or chain drives. It is driven by a single second drive motor, further reducing the production cost of the translation component. The lifting component and the translation component are directly linked through a first connecting plate, allowing the material handling tray group to synchronously adjust its horizontal and vertical positions during the lifting process, reducing waiting time between processes and improving production efficiency.

Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.
[0027] like Figures 1 to 3As shown, this utility model preferably provides a pulp molding station linkage device, which includes a frame body 10, a lifting assembly 20, and a translation assembly 30. The frame body 10 includes bases 11 spaced apart in the horizontal direction. The lifting assembly 20 is disposed above the bases 11 and includes lifting units 21, a transmission coupling 23, and a first drive motor 24. The number of lifting units 21 is at least two, and the two lifting units 21 are spaced apart in the horizontal direction. The transmission coupling 23 is disposed between the two lifting units 21. Each lifting unit 21 is provided with a first connecting plate 22 for connecting the translation assembly 30. The transmission coupling 23... One end of the translation component is connected to a first drive motor 24, which drives the two first connecting plates 22 to reciprocate in the vertical direction via a drive transmission coupling 23. The translation component 30 includes a translation gear 31, a translation rack 32, and a second drive motor 34. The translation gear 31 is arranged in a one-to-one correspondence with the first connecting plates 22, and the translation rack 32 is arranged horizontally between the two first connecting plates 22. One end of the translation component 30 is connected to a material picking tray assembly 40. The second drive motor 34 is connected to the translation gear 31. The rotation of the translation gear 31 drives the translation rack 32 to move in the horizontal direction, thereby driving the material picking tray assembly 40 to reciprocate in the horizontal direction.
[0028] Based on the above technical features, this utility model embodiment achieves a composite motion of vertical lifting and horizontal translation of the material handling tray group 40 through the coordinated design of the lifting component 20 and the translation component 30. The lifting component 20 includes two lifting units 21, a transmission coupling 23, and a first drive motor 24. The two lifting units 21 are mechanically linked through the transmission coupling 23 and driven by a single first drive motor 24, ensuring synchronous movement at both ends during the lifting process and avoiding equipment tilting or uneven load caused by asynchronous movement, thus effectively reducing manufacturing costs. The translation component 30 adopts a gear and rack transmission, which has higher positioning accuracy and repeatability compared to belt or chain transmission, and is driven by a single second drive motor 34, further reducing the production cost of the translation component 30. The lifting component 20 and the translation component 30 are directly linked through a first connecting plate 22, and the material handling tray group 40 can synchronously adjust its horizontal and vertical positions during the lifting process, reducing waiting time between processes and improving production efficiency.
[0029] As some embodiments of this utility model, such as Figure 2As shown, each lifting unit 21 includes a fixed frame 211, a lifting guide rail 222, and a lifting screw 223. The fixed frame 211 is positioned above the base 11. The lifting guide rail 222 and the lifting screw 223 are both located on one side of the fixed frame 211. There are two lifting guide rails 222, and the lifting screws 223 are located on opposite sides of each lifting guide rail 222. The fixed frame 211, positioned above the base 11, serves as a rigid support platform for the lifting unit 21 and is fixed to the base 11 with bolts to ensure overall stability. The lifting guide rail 222 provides precise guidance for the first connecting plate 22, ensuring that the lifting motion follows a predetermined path, reducing offset and swaying, and improving the smoothness and accuracy of the motion. The lifting screw 223 converts rotational motion into linear motion, driving the first connecting plate 22 to move vertically upwards and downwards, achieving precise position adjustment.
[0030] As some embodiments of this utility model, such as Figure 2 As shown, the top end of the lifting screw 223 is connected to the fixed frame 211, and the bottom end of the lifting screw 223 is fixed to the base 11 and connected to the transmission coupling 23. The lifting screw 223 is used to convert the rotational motion of the transmission coupling 23 into linear motion, thereby driving the connecting part on the lifting guide rail 222 to reciprocate in the vertical direction. The design of fixing both ends of the lifting screw 223 enhances the structural rigidity of the entire lifting unit 21, reduces the bending and vibration of the screw under force, and improves the stability of the lifting process. The lifting screw 223 accurately converts the rotational motion of the transmission coupling 23 into linear motion. This conversion method has high precision and high repeatability, which can ensure that the first connecting plate 22 on the lifting guide rail 222 moves accurately in the vertical direction. At the same time, the screw drive structure is simple and easy to maintain. Moreover, due to the fixed ends and precise motion conversion, the possibility of failure is reduced, and the reliability of the entire lifting system is improved.
[0031] As some embodiments of this utility model, such as Figure 1 As shown, the translation assembly 30 also includes two second connecting plates 35, which are fixedly connected to the first connecting plate 22. One end of one of the second connecting plates 35 is connected to a second drive motor 34, and the other end is connected to a translation gear 31. The second drive motor 34 passes through the second connecting plate 35 and connects to the translation gear 31, and the translation gear 31 meshes with the translation rack 32. The fixed connection between the second connecting plate 35 and the first connecting plate 22 ensures the stability of the translation assembly 30 with other structures and reduces motion errors caused by loosening or shaking. The second drive motor 34 directly passes through the second connecting plate 35 and connects to the translation gear 31, achieving a tight integration of drive and transmission. This design not only simplifies the structure but also improves the efficiency and stability of power transmission.
[0032] As some embodiments of this utility model, such as Figures 1 to 2 As shown, the translation rack 32 is a linear guide structure with continuous toothed surfaces. The translation gear 31 drives the translation rack 32 to move horizontally via rotation. The second drive motor 34 is connected to the translation gear 31 to provide rotational power. The linear guide structure of the translation rack 32 provides a clear linear motion trajectory for the translation gear 31, ensuring that the translation assembly 30 maintains linear motion throughout its movement and reducing motion errors caused by guide deviations. The close meshing between the translation gear 31 and the translation rack 32 makes power transmission more direct and efficient. The rotational power provided by the second drive motor 34 can be quickly and accurately converted into linear motion of the translation rack 32, reducing energy loss. Linear guide structures typically have a low coefficient of friction, further reducing energy loss during movement and improving transmission efficiency.
[0033] As some embodiments of this utility model, such as Figure 2 As shown, the translation component 30 also includes a support frame 36, which is positioned between the two lifting units 21 and extends horizontally. A translation rack 32 is positioned above and connected to the support frame 36. The support frame 36 is used to fix the translation rack 32 and guide its horizontal movement. The support frame 36, positioned between the two lifting units 21 and extending horizontally, provides a stable mounting platform for the translation rack 32. This layout creates an organic whole between the translation component 30 and the lifting units 21, facilitating complex motion control. The translation rack 32 is positioned above and connected to the support frame 36. The support frame 36 not only fixes the position of the translation rack 32 but also guides its horizontal movement. This design ensures the stability and accuracy of the translation rack 32 during movement.
[0034] As some embodiments of this utility model, such as Figures 1 to 3 As shown, the number of material picking tray assemblies 40 is the same as the number of translation gears 31. Each material picking tray assembly 40 includes a third connecting plate 41 and multiple suction cup components 42. One end of the third connecting plate 41 is fixedly connected to the support frame 36. The number of material picking tray assemblies 40 is the same as the number of translation gears 31. This design ensures that each translation gear 31 can drive one material picking tray assembly 40, achieving precise synchronization between translational movement and material picking action. Each material picking tray assembly 40 consists of a third connecting plate 41 and multiple suction cup components 42. The third connecting plate 41 serves as the mounting base for the suction cup components and is fixedly connected to the support frame 36, providing stable support for the suction cup components.
[0035] As some embodiments of this utility model, such as Figures 1 to 3 As shown, multiple suction cups 42 are spaced apart at the bottom of the third connecting plate 41. The suction cups 42 are used to adsorb the pulp molding product. The multiple suction cups 42 spaced apart at the bottom of the third connecting plate 41 allow the suction cups 42 to be evenly distributed, thereby adsorbing the pulp molding product more effectively.
[0036] As some embodiments of this utility model, such as Figure 1 As shown, there are two bases 11, and each base 11 has multiple fasteners 12 at its bottom. The fasteners 12 are located at the four corners of the base 11 and are used to secure the frame body. The use of two bases 11 is typically to provide a more stable support foundation, especially in equipment that needs to withstand large loads or perform high-precision motion control. Each base 11 has multiple fasteners 12 at its bottom, located at the four corners of the base 11. One end of each fastener 12 is fixedly connected to the ground, securing the device firmly to the ground and effectively improving its stability.
[0037] As some embodiments of this utility model, such as Figure 1 As shown, the frame body 10 also includes adjusting bolts 13. The number of adjusting bolts 13 is the same as the number of fasteners 12. The adjusting bolts 13 are respectively located at the four corners of the base 11, and are located at one end of the fasteners 12. The adjusting bolts 13 are detachably connected to the base 11. The frame body 10 is equipped with adjusting bolts 13, the number of which is equal to the number of fasteners 12. These adjusting bolts 13 are respectively installed at the four corners of the base, and are located at one end of the fasteners 12. The adjusting bolts 13 are detachably connected to the base 11 to facilitate subsequent installation, debugging, and maintenance.
[0038] In summary, the present invention provides a pulp molding station linkage device, which, compared with the prior art, has the following advantages: The device achieves a combined vertical lifting and horizontal translation of the material handling tray group 40 through the coordinated design of the lifting component 20 and the translation component 30; the lifting component 20 includes two lifting units 21, a transmission coupling 23, and a first drive motor 24. The two lifting units 21 are mechanically linked through the transmission coupling 23 and driven by a single first drive motor 24, ensuring synchronous movement at both ends during the lifting process and avoiding equipment tilting or uneven load due to asynchronous operation, effectively reducing manufacturing costs; the translation component 30 uses a rack and pinion drive, which has higher positioning accuracy and repeatability compared to belt or chain drive, and is driven by a single second drive motor 34, further reducing the production cost of the translation component 30; the lifting component 20 and the translation component 30 are directly linked through a first connecting plate 22, allowing the material handling tray group 40 to synchronously adjust its horizontal and vertical positions during the lifting process, reducing waiting time between processes and improving production efficiency.
