Description

Technical Field

[0001] This utility model relates to the field of tray separation technology, and in particular to a portable plasma tray lifting and separation device. Background Technology

[0002] Pallets, as a core carrier for loading, unloading, storage, and transportation in logistics, are widely used in production, warehousing, and distribution. To improve stacking stability, pallets are typically designed with interlocking protrusions and grooves. However, this design has significant drawbacks when retrieving items: when retrieving items (such as blood plasma) from the bottom of a stack of pallets, the weight of the upper pallets makes it difficult to separate the lower ones. Operators often need to use tools such as pry bars to forcibly pry them open, which is not only inefficient but also poses significant safety hazards. Especially in special scenarios such as blood plasma storage, frequent manual intervention increases the risk of contamination, and the prying process can easily damage the pallet structure, affecting its service life.

[0003] In the prior art, Chinese patent CN202010433830.9 discloses a tray separation device. This device uses separation mechanisms located on the left and right sides of the tray. The separation mechanism includes a base plate, a separation plate slidably mounted on the base plate, and a cylinder that drives the separation plate to slide. When the separation plate slides left and right relative to the base plate, a part of the separation plate extends into the gap between two stacked trays, achieving the technical effect of preventing the lower tray from moving when the upper tray moves upward. By setting a guide slope at an acute angle to the sliding direction of the separation plate on the separation plate, and setting a connecting block on the cylinder rod, the end of the connecting block away from the cylinder rod contacts the guide slope. When the cylinder rod extends and retracts in the front-back direction, the contact between the connecting block and the guide slope can drive the separation plate to slide left and right.

[0004] While the aforementioned device possesses the advantages of separating trays, it still has the following shortcomings in practical use: First, it relies on the lateral drive of cylinders, requiring precise control of the cylinder stroke during the separation process, which places high demands on the coordination of the automated system and limits its applicability in confined spaces or non-automated environments; second, the separation plate slides through the contact block via an inclined surface, and long-term use can easily lead to wear of components due to friction, affecting separation accuracy and reliability; third, the device is mainly designed for general trays and lacks portability and adaptability optimization for special scenarios such as plasma trays, making it difficult to meet the medical field's needs for rapid and safe operation. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies, such as poor applicability, low separation accuracy and reliability, and to provide a portable plasma tray lifting and separation device.

[0006] This utility model is achieved through the following technical solution: a portable plasma tray lifting and separating device, comprising a lifting main body box and an electrically controlled drive assembly. The top side of the lifting main body box is an open structure, and a sliding plate is provided at the bottom inner side of the lifting main body box. The sliding plate is slidably connected to the inner side wall of the lifting main body box. Several equidistant fixed vertical plates are provided on the top side of the sliding plate, and a moving rod is fixedly provided on the top side of the fixed vertical plate. A fixed horizontal shaft is provided above each fixed vertical plate, located at the top inner side of the lifting main body box. The two ends of the fixed horizontal shaft are respectively connected to the inner side wall of the lifting main body box, and the fixed horizontal shaft is... Symmetrically arranged rotating plates are rotatably mounted on the outer sides of both ends of the fixed horizontal axis; the top of the rotating plate is used to lift the pallet, and the bottom of the rotating plate is provided with a guide straight groove, and the rotating plate is slidably connected to the moving rod through the guide straight groove; the electric control drive assembly is located on the inner bottom side of the lifting main body box, and the electric control drive assembly is connected to the sliding plate. The electric control drive assembly can drive the sliding plate to move laterally back and forth, so that the fixed vertical plate can drive the rotating plate to rotate around the fixed horizontal axis through the moving rod, thereby enabling the top of the rotating plate to lift the pallet above it, and enabling the pallet to be separated.

[0007] This invention achieves automated lifting and separation of pallets through an open top-side structure of the lifting main body box, a linkage design between the sliding plate and the fixed vertical plate, and an electronically controlled drive assembly that drives the rotating plate to rotate around a fixed horizontal axis. This structure avoids the risks of manual prying, while the compact box design facilitates insertion into pallet gaps, significantly improving operational safety and portability.

[0008] A further improvement of this invention is that the rotating plate is a crank arm structure, and the center of the rotating plate is rotatably connected to a fixed horizontal axis. The crank arm structure and the rotatable connection between the center of the rotating plate and the fixed horizontal axis form a stable lever fulcrum, ensuring uniform force distribution on the rotating plate during lifting, reducing the risk of mechanical deformation, and enhancing the overall structural strength and reliability of the device.

[0009] A further improvement of this invention is that the guide slot is a straight groove, the length of which is adapted to the rotation trajectory of the rotating plate, and the end of the moving rod slides in contact with the inner wall of the guide slot. The straight design of the guide slot and its adaptation to the rotation trajectory make the sliding process of the moving rod smoother, precisely control the rotation angle of the rotating plate, and improve the stability and separation accuracy of the lifting action.

[0010] A further improvement of this utility model is that a mounting groove is provided at the top of the rotating plate, and a pulley with an axle is installed in the mounting groove. The axis of the pulley, the axis of the fixed horizontal axis, and the axis of the moving rod are parallel, and the outer surface of the pulley is covered with an anti-slip rubber layer. The pulley is integrated into the top of the rotating plate through the mounting groove. Its axis is parallel to the fixed horizontal axis and its surface is covered with an anti-slip rubber layer, which reduces the lifting friction and prevents the pallet from sliding or deviating, ensuring a smooth and controllable lifting process and adapting to pallets with different surface materials.

[0011] A further improvement of this invention is that the rotation angle range of the rotating plate is 0° to 45°. When the top of the rotating plate is at its maximum rotation angle, the pulley can fully extend out to the top side of the lifting main body box. This invention limits the maximum rotation angle of the rotating plate to 45°, so that the pulley can fully lift the upper tray when fully extended, while avoiding excessive rotation that could cause structural interference. This balances separation efficiency and device safety, and is suitable for application scenarios with different stacking heights.

[0012] A further improvement of this utility model is that the electric control drive assembly includes a power supply, a relay, a control line, and an electric push cylinder. The power supply and the relay constitute a power supply unit, which is located on the outer wall of one end of the lifting main body box. The power supply unit is electrically connected to the electric push cylinder via the control line. The electric push cylinder is located on the inner bottom side of the lifting main body box and is connected to the sliding plate via a connecting plate. The relay controls the extension and retraction of the electric push cylinder to drive the sliding plate to move. The electric control drive assembly integrates the power supply, relay, and electric push cylinder, enabling one-button operation via the control line, simplifying the human-machine interaction process, shortening separation time, and facilitating maintenance and quick replacement of the external power supply unit.

[0013] A further improvement of this invention is that the electric push cylinder is fixed to the bottom side of the lifting main body box by a fixed mounting block, and the extension and retraction direction of the electric push cylinder is consistent with the movement direction of the sliding plate. The electric push cylinder is rigidly connected to the bottom side of the lifting main body box by the fixed mounting block, and its extension and retraction direction is consistent with the movement direction of the sliding plate, ensuring efficient transmission of driving force, reducing energy loss, and improving the operating efficiency of the device.

[0014] A further improvement of this invention is that the inner sidewalls on both sides of the lifting main body box are provided with sliding grooves corresponding to the sliding plates. Both sides of the sliding plates are slidably connected to the sliding grooves via wear-resistant bushings made of polytetrafluoroethylene (PTFE) or nylon. The use of PTFE or nylon wear-resistant bushings between the sliding plates and the sliding grooves significantly reduces the coefficient of sliding friction, extends the service life of the device, reduces maintenance frequency, and lowers long-term operating costs.

[0015] A further improvement of this utility model is that a handle is provided at one end of the lifting main body box, and the handle is integrally formed with the lifting main body box or detachably connected. The integrated or detachable handle design at the front end of the lifting main body box facilitates one-handed carrying and precise insertion into the tray gap, improving the portability of the device, and is especially suitable for temporary operations or operation in confined spaces.

[0016] A further improvement of this invention is that the size of the lifting main body box is adapted to the gap width of a standard plasma tray, and its thickness does not exceed 50mm. The lifting main body box, with a thickness ≤50mm and adapted to the standard tray gap width, ensures the device's lightweight and versatility, allowing it to be directly embedded into existing logistics or medical tray systems without requiring infrastructure modifications, thus reducing deployment costs.

[0017] As can be seen from the above technical solutions, the beneficial effects of this utility model are:

[0018] 1. This utility model achieves automated lifting and separation through an electrically controlled drive component (electric push cylinder with relay), completely eliminating the risk of tray tipping and personnel injury in traditional pry bar operations. It is especially suitable for the handling of sensitive items such as blood plasma, and can completely replace high-risk manual prying, significantly improving operational safety.

[0019] 2. This utility model uses a relay to control the extension and retraction of the electric push cylinder, realizing the instant lifting and separation of the pallet. The operation is quick and requires no complicated training, greatly improving work efficiency. At the same time, the thickness of the lifting main box is ≤50mm, which is compatible with standard pallet gaps. It is equipped with a handle for one-handed carrying and easy insertion into the gaps between stacked pallets, making it suitable for temporary operations or confined spaces.

[0020] 3. The rotating plate (0° to 45°) of this utility model has an adjustable angle, and the pulley lifting height can flexibly adapt to different stacking layers to meet diverse needs such as medical and warehousing. Furthermore, the low-friction cooperation between the moving rod and the guide straight groove, and the application of wear-resistant bushings (PTFE / nylon) significantly reduce mechanical wear, extend service life, and reduce maintenance frequency and cost.

Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0026] Please refer to the attached document. Figure 1 and 2 The following is a description of a specific embodiment: The portable plasma tray lifting and separating device of this utility model includes a lifting main body box 1 and an electrically controlled drive assembly. The top side of the lifting main body box 1 is an open structure, and the size of the lifting main body box 1 is adapted to the gap width of a standard plasma tray, with a thickness not exceeding 50mm. A sliding plate 7 is provided at the inner bottom of the lifting main body box 1, and the sliding plate 7 is slidably connected to the inner side wall of the lifting main body box 1. Several equidistant fixed vertical plates 8 are provided on the top side of the sliding plate 7, and a moving rod 9 is fixedly provided on the top side of the fixed vertical plate 8. A fixed horizontal shaft 13 is respectively provided above each fixed vertical plate 8, located at the top of the lifting main body box 1, and both ends of the fixed horizontal shaft 13 are respectively connected to… The inner walls of the lifting main body box 1 are connected, and symmetrically arranged rotating plates 2 are respectively rotatably sleeved on the outer sides of both ends of the fixed horizontal shaft 13; the top of the rotating plate 2 is used to lift the pallet, and the bottom of the rotating plate 2 is provided with a guide straight groove 14, and the rotating plate 2 is slidably connected to the moving rod 9 through the guide straight groove 14; the electric control drive assembly is set on the inner bottom side of the lifting main body box 1, and the electric control drive assembly is connected to the sliding plate 7. The electric control drive assembly can drive the sliding plate 7 to move laterally back and forth, so that the fixed vertical plate 8 can drive the rotating plate 2 to rotate around the fixed horizontal shaft 13 through the moving rod 9, thereby enabling the top of the rotating plate 2 to lift the pallet above it, and enabling the pallet to be separated.

[0027] The lifting main body box 1 of this utility model has an open top structure. The sliding plate 7 moves laterally under the drive of the electronically controlled drive assembly, causing the fixed vertical plate 8 and the moving rod 9 to move synchronously. The two ends of the moving rod 9 are inserted into the guide slots 14 at the bottom of the rotating plate 2, pushing the rotating plate 2 to rotate around the fixed horizontal axis 13, and its top end lifts the upper pallet to achieve separation. The lifting main body box 1 is easy to insert into the pallet gap, and the electronically controlled drive replaces manual prying, significantly improving operational safety. Moreover, the modular linkage structure ensures stable and efficient lifting action. Furthermore, the lifting main body box 1 has a thickness of ≤50mm and its size is adapted to the standard pallet gap width, allowing it to be directly embedded in stacked pallets. This design effectively improves the versatility of this utility model, allowing deployment without modifying existing pallet systems and reducing equipment upgrade costs for enterprises.

[0028] For details, please refer to the appendix. Figure 2 The rotating plate 2 is a crank arm structure, and its center is rotatably connected to the fixed horizontal shaft 13. The rotating plate 2 employs a crank arm structure, with its center rotatably connected to the fixed horizontal shaft 13, forming a lever fulcrum. When the moving rod 9 slides, it drives the crank arm to rotate around the axis through the guide slot 14. The crank arm structure design enhances the rigidity of the rotating plate 2, and the central fulcrum design distributes the force, thereby reducing component wear and extending the service life of the device.

[0029] For details, please refer to the appendix. Figure 2 The guide slot 14 is a straight slot, and its length direction is adapted to the rotation trajectory of the rotating plate 2. The end of the moving rod 9 slides in contact with the inner wall of the guide slot 14. The end of the moving rod 9 slides along the straight slot, precisely controlling the angle of the rotating plate 2. The straight slot is adapted to the rotation trajectory, realizing stepless angle adjustment, thereby improving the lifting and separation accuracy and avoiding incomplete separation or over-lifting.

[0030] For details, please refer to the appendix. Figure 2 The electric drive assembly includes a power supply 4, a relay 5, a control line 6, and an electric push cylinder 11. The power supply 4 and the relay 5 constitute a power supply unit, which is located on the outer side wall of one end of the lifting main body box 1. The power supply unit is electrically connected to the electric push cylinder 11 through the control line 6. The electric push cylinder 11 is located on the inner bottom side of the lifting main body box and is connected to the sliding plate 7 through the connecting plate 10. The relay 5 controls the extension and retraction of the electric push cylinder 11 to drive the sliding plate 7 to move.

[0031] Referring to existing electrical designs, the power supply 4 and the relay 5 constitute the power supply unit of the device. This power supply unit drives the electric push cylinder 11 to extend and retract via the control line 6. The electric push cylinder 11 pushes the sliding plate 7 to move laterally via the connecting plate 10. This one-button electrical control operation simplifies the process, and the external power supply unit facilitates maintenance, significantly improving work efficiency and ease of operation.

[0032] In one embodiment, reference is made to the appendix. Figure 2 The rotating plate 2 has a mounting groove 15 at its top, and a pulley 16 with an axle is installed in the mounting groove 15. The axis of the pulley 16, the axis of the fixed horizontal shaft 13, and the axis of the moving rod 9 are parallel, and the outer surface of the pulley 16 is covered with an anti-slip rubber layer. The rolling of the pulley 16 replaces the traditional sliding lifting, reducing the contact friction with the pallet, improving lifting efficiency, and reducing energy consumption. Moreover, the anti-slip rubber layer can increase friction, prevent the pallet from shifting or slipping during the lifting process, and ensure precise and controllable separation action. The three-axis parallel design (pulley 16, fixed horizontal shaft 13, and moving rod 9) can ensure the consistency of the transmission trajectory, avoid mechanical jamming or wear caused by axis deviation, and extend the service life of the device.

[0033] In one embodiment, reference is made to the appendix. Figure 2 The rotating plate 2 has a rotation angle range of 0° to 45°. When the top of the rotating plate 2 is at its maximum rotation angle, the pulley 16 can fully extend out of the top side of the lifting main body box 1. The maximum rotation angle of the rotating plate 2 is 45°. When the pulley 16 is fully extended out of the lifting main body box 1, it lifts the pallet to the separation height and then returns to its original position. This angle-limited design avoids structural interference, balances separation efficiency and device safety, and is suitable for pallet scenarios with different stacking heights.

[0034] In one embodiment, reference is made to the appendix. Figure 2 The electric push cylinder 11 is fixed to the bottom side of the lifting main body box 1 by a fixed mounting block 12, and the extension and retraction direction of the electric push cylinder 11 is consistent with the movement direction of the sliding plate 7. The above rigid fixation ensures the linear transmission of driving force, thereby reducing energy loss and improving the operational stability and response speed of the device.

[0035] In one embodiment, the inner sidewalls of both sides of the lifting main body box 1 are provided with grooves corresponding to the sliding plate 7. Both sides of the sliding plate 7 are slidably connected to the grooves via wear-resistant bushings made of polytetrafluoroethylene (PTFE) or nylon. The slidable connection between the two sides of the sliding plate 7 and the grooves via wear-resistant bushings made of PTFE or nylon reduces frictional resistance. This low-friction material effectively extends the lifespan of the sliding components, reduces maintenance frequency, and ensures long-term reliable operation of the device.

[0036] In one embodiment, reference is made to the appendix. Figure 2 One end of the lifting main body box 1 is equipped with a handle 3, which is integrally formed with or detachably connected to the lifting main body box 1. The lifting main body box 1 is equipped with an integral or detachable handle 3 for easy hand operation. This user-friendly handle design greatly improves portability, supports one-handed operation for quick insertion into the tray gap, and adapts to the needs of working in narrow spaces.
