Description

Technical Field

[0001] This utility model relates to the field of article flipping technology, and more specifically, to a flipping device. Background Technology

[0002] When storing milk powder cans, to reduce the probability of dust and foreign objects entering the cans, the cans should be stored with the opening facing down. Before transporting the milk powder cans to the packaging process in the milk powder production workshop, the cans need to be turned upside down so that the opening faces upwards, making it easier for the packaging process to handle the cans.

[0003] In related technologies, the flipping of milk powder cans requires manual operation by staff. Milk powder cans are stacked during storage, and staff flip these stacks. During the flipping process, cans at the edges are compressed against the ground, leading to deformation and damage. Utility Model Content

[0004] The main purpose of this invention is to provide a flipping device to solve the problem in related technologies where milk powder cans are easily squeezed and deformed when operators manually flip them.

[0005] To achieve the above objectives, one aspect of this utility model provides a flipping device, comprising: a base; a first hydraulic cylinder disposed on the base, the first hydraulic cylinder including a cylinder barrel fixedly disposed on the base and a piston rod disposed vertically within the cylinder barrel; a hydraulic pump disposed on the base and connected to the cylinder barrel; a handle swayably disposed on the base, the handle being connected to the pressure rod of the hydraulic pump, the handle swaying to increase or decrease the pressure within the hydraulic pump, thereby pushing the piston rod up or down; a rotating shaft rotatably connected to the piston rod, the piston rod rising or falling to drive the rotating shaft to rise or fall; and a clamping structure fixedly connected to the rotating shaft, the rotating shaft rotating to drive the clamping structure to rotate.

[0006] Furthermore, the clamping structure includes a mounting plate fixedly connected to the rotating shaft and a first clamping arm and a second clamping arm disposed at opposite ends of the mounting plate, the first clamping arm and / or the second clamping arm being movably disposed on the mounting plate.

[0007] Furthermore, the flipping device also includes a limiting cylinder fixedly mounted on the piston rod. The limiting cylinder is sleeved outside the rotating shaft. A floating ball is provided on the limiting cylinder and can be floated along the axial direction of the limiting cylinder. Multiple limiting notches are provided on the rotating shaft and are spaced apart circumferentially along the rotating shaft. The floating ball has a limiting position that extends into the limiting notch and a clearance position that exits from the limiting notch. The floating ball can selectively extend into one of the multiple limiting notches.

[0008] Furthermore, there is a clearance gap between the limiting cylinder and the mounting plate.

[0009] Furthermore, the clamping structure also includes a telescopic rod connected between the first clamping arm and the second clamping arm. The telescopic rod shortens to bring the first clamping arm and the second clamping arm closer together and clamp the item, and extends to move the first clamping arm and the second clamping arm away from each other and release the item.

[0010] Furthermore, the telescopic rod is a second hydraulic cylinder, and the tilting device also includes an electromagnetic reversing valve for controlling the direction of fluid flow in the second hydraulic cylinder, as well as a control button connected to the electromagnetic reversing valve.

[0011] Furthermore, the flipping device also includes a column mounted on the base, located on the side of the mounting plate opposite to the first clamping arm, and the control button is located on the column.

[0012] Furthermore, a grip handle is fixedly installed on the mounting plate, and the mounting plate can be rotated by driving the grip handle.

[0013] Furthermore, the flipping device also includes a bearing disposed between the piston rod and the rotating shaft. The outer ring of the bearing is fixedly disposed on the piston rod, the inner ring of the bearing is fixedly disposed on the rotating shaft, and the inner ring of the bearing is rotatably disposed inside the outer ring of the bearing.

[0014] Furthermore, the flipping device also includes multiple movable wheels disposed below the seat, with the multiple movable wheels spaced apart.

[0015] The flipping device, utilizing the technical solution of this utility model, includes: a base, a first hydraulic cylinder, a hydraulic pump, a handle, a rotating shaft, and a clamping structure. The first hydraulic cylinder is mounted on the base and includes a cylinder barrel fixedly mounted on the base and a piston rod vertically mounted within the cylinder barrel. The hydraulic pump is mounted on the base and communicates with the cylinder barrel. The handle is pivotally mounted on the base and connected to the pressure rod of the hydraulic pump. Pivoting the handle increases or decreases the pressure within the hydraulic pump, thereby pushing the piston rod up or down. The rotating shaft is rotatably connected to the piston rod, and the piston rod's movement drives the rotating shaft to move up or down. The clamping structure is fixedly connected to the rotating shaft, and the rotating shaft's rotation drives the clamping structure to rotate. Thus, by driving the handle to pivot, the pressure within the hydraulic pump can change, thereby pushing the piston rod up or down, causing the rotating shaft to be driven to rise or fall, and consequently, the clamping structure fixedly connected to the rotating shaft can rise or fall. Furthermore, since the rotating shaft is rotatably connected to the piston rod, its rotation drives the clamping structure to rotate. The operator places the milk powder can within the clamping structure, allowing the structure to hold it. A drive handle swings, causing the clamping structure to lift the can off the ground. A drive shaft rotates, causing the clamping structure to rotate and thus tip the can over. This avoids contact between the can and the ground, reducing the possibility of deformation and minimizing wear and tear. Therefore, the technical solution of this application effectively solves the problem in related technologies where milk powder cans are easily deformed when manually tipped over.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0030] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0031] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0032] Applying the technical solution of this embodiment, such as Figures 1 to 3 As shown, the tilting device includes: a base 10, a first hydraulic cylinder 20, a hydraulic pump 80, a handle 30, a rotating shaft 40, and a clamping structure 50. The first hydraulic cylinder 20 is mounted on the base 10 and includes a cylinder barrel 21 fixedly mounted on the base 10 and a piston rod 22 vertically mounted within the cylinder barrel 21. The hydraulic pump 80 is mounted on the base 10 and communicates with the cylinder barrel 21. The handle 30 is pivotally mounted on the base 10 and connected to the pressure rod of the hydraulic pump 80. Pivoting the handle 30 increases or decreases the pressure within the hydraulic pump 80, thereby pushing the piston rod 22 up or down. The rotating shaft 40 is rotatably connected to the piston rod 22. The piston rod 22 rises or falls, causing the rotating shaft 40 to rise or fall. The clamping structure 50 is fixedly connected to the rotating shaft 40, and the rotation of the rotating shaft 40 causes the clamping structure 50 to rotate.

[0033] In this way, by swinging the drive handle 30, the pressure inside the hydraulic pump 80 changes, thereby pushing the piston rod 22 up or down. This causes the rotating shaft 40 to rise or fall, which in turn causes the clamping structure 50, which is fixedly connected to the rotating shaft 40, to rise or fall. Furthermore, since the rotating shaft 40 is rotatably connected to the piston rod 22, its rotation drives the clamping structure 50 to rotate. The operator places the milk powder can inside the clamping structure 50, allowing it to hold the can. Swinging the drive handle 30 causes the clamping structure 50 to lift the can off the ground. Rotating the rotating shaft 40 causes the clamping structure 50 to rotate, thus flipping the can. This avoids contact between the can and the ground, reducing the possibility of deformation and wear. Therefore, the technical solution of this embodiment effectively solves the problem in related technologies where milk powder cans are easily deformed when manually flipped by the operator.

[0034] In this embodiment, the hydraulic cylinder is fixed to the base 10, and a movable first piston is disposed inside the hydraulic cylinder. The hydraulic cylinder comprises two main parts: a rod chamber and a rodless chamber, and a piston rod 22 is connected to one end of the cylinder barrel 21. The piston rod 22 is connected to the first piston inside the cylinder barrel 21. When hydraulic oil is pressed into the cylinder barrel 21, the hydraulic oil pushes the first piston and the piston rod 22 to move. A second piston and a pressure rod connected to the second piston are disposed inside the hydraulic pump 80. The handle 30 is swung to drive the second piston to move inside the hydraulic pump 80 through the pressure rod, so that the pressure in the chamber of the hydraulic pump 80 connected to the cylinder barrel 21 can change, thereby driving the first piston inside the first hydraulic cylinder 20 to move. The connection method between the handle 30 and the hydraulic pump 80 in this embodiment is the same as the connection method between the handle and the pump body assembly in Chinese Invention Patent Publication No. CN102562512B.

[0035] like Figures 1 to 3 As shown, the clamping structure 50 includes a mounting plate 51 fixedly connected to the rotating shaft 40, and a first clamping arm 52 and a second clamping arm 53 disposed at opposite ends of the mounting plate 51. The first clamping arm 52 and the second clamping arm 53 are movably disposed on the mounting plate 51. The movable arrangement of the first clamping arm 52 and the second clamping arm 53 facilitates the clamping and releasing of the milk powder can by the clamping structure 50, and can adapt to items of different sizes, enhancing the versatility and practicality of the flipping device. Especially when handling goods of different sizes, it can quickly adjust the clamping range and improve work efficiency. The movable arrangement of the first clamping arm 52 and the second clamping arm 53 on the mounting plate 51 improves the clamping efficiency of the clamping structure 50.

[0036] In other embodiments, the first clamping arm 52 or the second clamping arm 53 is movably disposed on the mounting plate 51.

[0037] like Figures 1 to 3 As shown, the flipping device also includes a limiting cylinder 60 fixedly mounted on the piston rod 22, which is sleeved around the rotating shaft 40. A floating ball 61 is provided on the limiting cylinder 60 and is buoyantly mounted along its axial direction. Multiple limiting notches are provided on the rotating shaft 40, spaced circumferentially. The floating ball 61 has a limiting position extending into the limiting notch and a clearance position exiting from the limiting notch. The floating ball 61 can selectively extend into one of the multiple limiting notches. The arrangement of the limiting cylinder 60, floating ball 61, and limiting notches better holds the rotating shaft 40 in a specific position, allowing the milk powder can within the clamping structure 50 to remain stationary when not subjected to external force. This facilitates holding the milk powder can with its opening facing upwards, making it easier to handle during packaging, reducing impacts to the milk powder can, and improving operational safety. The limiting cylinder 60, floating ball 61, and limiting notches have a simple structure, making them easy to manufacture and assemble.

[0038] like Figures 1 to 3 As shown, there is a clearance between the limiting cylinder 60 and the mounting plate 51. The clearance design avoids direct contact between the limiting cylinder 60 and the mounting plate 51, reduces friction, makes the rotation of the rotating shaft 40 smoother, and extends the service life of the equipment.

[0039] like Figures 1 to 3As shown, the clamping structure 50 also includes a telescopic rod 54 connected between the first clamping arm 52 and the second clamping arm 53. The telescopic rod 54 shortens to bring the first clamping arm 52 and the second clamping arm 53 closer together to clamp the item. The telescopic rod 54 extends to move the first clamping arm 52 and the second clamping arm 53 away from each other to release the item. The use of the telescopic rod 54 allows the clamping structure 50 to clamp and release milk powder cans or other items more flexibly, improving operational convenience. The telescopic rod 54 has a simple structure, making it easy to manufacture and assemble.

[0040] like Figures 1 to 3 As shown, the telescopic rod 54 is the second hydraulic cylinder. The tilting device also includes an electromagnetic directional valve that controls the direction of fluid flow within the second hydraulic cylinder, and a control button 711 connected to the electromagnetic directional valve. By controlling the direction of fluid flow through the electromagnetic directional valve, the extension and retraction of the second hydraulic cylinder are controlled, achieving automated operation and improving work efficiency. Operators can control the extension and retraction of the telescopic rod 54 by operating the control button 711, thereby controlling the clamping structure 50's clamping and releasing of the milk powder can; the operation is simple and quick.

[0041] like Figures 1 to 3 As shown, the flipping device also includes a column 71 mounted on the base 10. The column 71 is located on the side of the mounting plate 51 opposite to the first clamping arm 52, and the control button 711 is mounted on the column 71. The column 71 not only enhances the stability of the base 10, but also facilitates the operation of the control button 711 by the operator, thus improving the convenience and safety of operation.

[0042] like Figures 1 to 3 As shown, a handle is fixedly installed on the mounting plate 51. By driving the handle, the mounting plate 51 can be rotated. The design of the handle makes it easy for the operator to drive the mounting plate 51 to rotate by gripping the handle, which allows the operator to manually control the rotation of the mounting plate 51 to make the milk powder can flip over, increasing the convenience and flexibility of operation.

[0043] like Figures 1 to 3 As shown, the flipping device also includes a bearing disposed between the piston rod 22 and the rotating shaft 40. The outer ring of the bearing is fixedly disposed on the piston rod 22, and the inner ring of the bearing is fixedly disposed on the rotating shaft 40. The inner ring of the bearing is rotatably disposed inside the outer ring of the bearing. The use of the bearing reduces the friction when the rotating shaft 40 rotates, improves the smoothness and stability of the rotation of the rotating shaft 40, thereby making the flipping of the milk powder can smoother, easier, and more stable.

[0044] In this embodiment, the bearing is a radial thrust bearing, which can better withstand radial and axial loads.

[0045] like Figures 1 to 3As shown, the flipping device also includes multiple casters 72 disposed below the base 10, with the casters 72 spaced apart. The design of the casters 72 allows the flipping device to move easily on the ground, improving the device's convenience and making it suitable for scenarios where items need to be moved between different work areas. This allows the flipping device to not only flip milk powder cans but also transport them.

[0046] The inventors discovered that in related technologies, each milk powder can weighs 800 grams, and each stack of milk powder cans weighs 75 kilograms. Turning over each stack of milk powder cans requires two to three operators to do it manually. This is labor-intensive, has high labor costs, and is prone to problems such as milk powder cans being crushed and personnel being bumped or knocked over.

[0047] By applying the technical solution of this embodiment, the turning time of each stack of milk powder cans can be controlled within one minute, and it can be completed by a single person. The operation is simple, reduces labor costs, and improves safety.

[0048] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" 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. Unless otherwise stated, these directional terms 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, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0049] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0050] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0051] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
