Description

Technical Field

[0001] This utility model relates to the field of plastic cup production technology, and in particular to a plastic cup flipping device. Background Technology

[0002] In the production process of plastic cups, cup flipping technology plays a crucial role. After injection molding, cooling, and initial inspection, the plastic cups need to be flipped to adjust their orientation for subsequent processing steps, such as printing, heat sealing, or assembly. This flipping is not only to meet the needs of the process flow but also to ensure the smooth flow of plastic cups on automated production lines.

[0003] Chinese patent CN222203915U discloses a product flipping device, including a guiding mechanism and a blocking mechanism. The guiding mechanism includes a guide member and a guide sleeve. The guide member is disposed on a conveying device and is inclined from bottom to top towards the conveying direction. The guide member extends along the inclined direction, and the guide sleeve is sleeved on the guide member and can slide along the extension direction of the guide member. The blocking mechanism is disposed on the guide sleeve and can abut against the product. When the product abuts against the blocking mechanism, the conveying device applies a force to the bottom surface of the product in the conveying direction, and the blocking mechanism applies a force to the top of the product opposite to the conveying direction. Under the combined action of these two forces, the product will flip in a direction away from the conveying direction. This product flipping device can realize automatic product flipping without manual operation, making flipping convenient. In addition, the device does not require any driving components, thus having low energy consumption and low cost.

[0004] For products like plastic cups, which have unique shapes and materials, the design of this flipping device has certain limitations. Plastic cups typically have a circular or cylindrical structure, and their walls are relatively thin, making them prone to deformation or damage during the flipping process.

[0005] In actual production, the flipping process of plastic cups often presents certain challenges. Because plastic cups are thin and easily deformed, they are prone to damage or deformation during the flipping process, affecting the overall quality and usability of the cups. In addition, if the flipping operation is not precise enough, it will lead to inconvenience in subsequent operations, reduce production efficiency, and increase production costs. Utility Model Content

[0006] In view of the technical problems existing in the background art, the purpose of this utility model is to provide a plastic cup flipping device to solve the problem mentioned in the background art that the plastic cup material is thin and easily deformed, which can easily cause damage or deformation during the flipping process, affecting the overall quality and use effect of the plastic cup.

[0007] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0008] A plastic cup flipping device includes a support assembly, a drive assembly, a flipping assembly, and an adsorption assembly. The drive assembly is located on the right side of the support assembly, and the flipping assembly is connected to the left side of the drive assembly. An adsorption assembly is located at the front end of the flipping assembly. The support assembly includes a support frame, with slide rails fixed to the upper and lower ends of the left side of the support frame. The flipping assembly includes a transverse plate, with sliders fixed to the upper and lower ends of the rear side of the transverse plate. The sliders are slidably mounted on the outside of the slide rails. A rotating rod is movably mounted in the middle of the transverse plate via a first bearing, and an adsorption assembly is located at the front end of the rotating rod.

[0009] Preferably, a support plate is fixed to the rear side of the support frame, and a groove is formed in the middle of the support plate.

[0010] Preferably, the groove is V-shaped in the middle, and a connecting block is fixed to the rear end of the rotating rod. A second bearing is provided at the rear end of the connecting block, and the second bearing is movably installed inside the groove.

[0011] Preferably, the drive assembly includes a wheel that is movably mounted on the right side of the support frame.

[0012] Preferably, a first connecting rod is connected to the edge of the wheel, and the other end of the first connecting rod is connected to the transverse plate.

[0013] Preferably, a second connecting rod is fixed to the rear end of the wheel, and the wheel is movably connected to the support frame through the second connecting rod. A synchronous wheel is fixed to the rear end of the second connecting rod.

[0014] Preferably, the adsorption assembly includes an adsorption base, which is fixed to the front end of the rotating rod. An extension rod is fixed to the right side of the adsorption base, and a suction cup is installed on the right side of the extension rod.

[0015] Preferably, the extension rod has a hollow structure, and an air pressure port is provided on one side of the extension rod.

[0016] This utility model has the following advantages and beneficial effects:

[0017] In this invention, the adsorption component grips the plastic cup with a uniform and stable adsorption force. Combined with the smooth rotation of the rotating rod and the first bearing, and the guide and limiting of the rotating rod by the groove, it effectively avoids damage during flipping due to the thin and easily deformable material of the plastic cup. The slide rail and slider ensure the precise movement of the transverse plate, and the groove ensures that the rotating rod rotates along a predetermined trajectory. The coordinated work of all components improves the accuracy of the flipping operation, allowing the plastic cup to be accurately positioned for subsequent operations, thereby increasing production efficiency and reducing production costs.

Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0024] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0025] Example

[0026] like Figures 1-4As shown, a plastic cup flipping device includes a support assembly 1, a drive assembly 2, a flipping assembly 3, and an adsorption assembly 4. The drive assembly 2 is located on the right side of the support assembly 1, and the flipping assembly 3 is connected to the left side of the drive assembly 2. The adsorption assembly 4 is located at the front end of the flipping assembly 3. The support assembly 1 includes a support frame 11, and slide rails 111 are fixed to the upper and lower ends of the left side of the support frame 11. The flipping assembly 3 includes a transverse plate 31, and sliders 311 are fixed to the upper and lower ends of the rear side of the transverse plate 31. The sliders 311 are slidably mounted on the outside of the slide rails 111. The transverse plate 31 is flexibly connected to the middle of the transverse plate 31 via a first bearing 33. A rotating rod 32 is movably mounted, with an adsorption component 4 at its front end. A support plate 12 is fixed to the rear side of the support frame 11, and a groove 121 is formed in the middle of the support plate 12. The groove 121 is V-shaped. A connecting block 321 is fixed to the rear end of the rotating rod 32, and a second bearing 34 is provided at the rear end of the connecting block 321. The second bearing 34 is movably mounted inside the groove 121 and is eccentrically positioned with respect to the rotating rod 32. When the second bearing 34 slides in the groove 121, the connecting block 321 can drive the rotating rod 32 to rotate, achieving a flipping effect.

[0027] like Figures 1-4 As shown, during use, a rotating rod 32 is movably mounted in the middle of the transverse plate 31 via a first bearing 33, allowing the rotating rod 32 to rotate flexibly. During the flipping process, the rotation of the rotating rod 32 is relatively smooth. The V-shaped groove 121 in the middle of the support plate 12 provides guidance and limitation for the rotation of the rotating rod 32, making its movement trajectory more controllable and stable. This ensures a smooth flipping action when flipping the plastic cup. The cooperation between the slide rail 111 and the slider 311 allows the transverse plate 31 to accurately move to the designated position during the plastic cup flipping operation, enabling the adsorption assembly 4 to accurately grasp and place the plastic cup, thus improving the accuracy of the flipping operation.

[0028] like Figures 1-4 As shown, the drive assembly 2 includes a wheel 21, which is movably mounted on the right side of the support frame 11. A first connecting rod 22 is hinged to the edge of the wheel 21, and the other end of the first connecting rod 22 is hinged to the transverse plate 31. When the wheel 21 rotates in a circular motion under the drive of an external power source, the connecting rod mounted on its edge moves accordingly. One end of the first connecting rod 22 is connected to the wheel 21, and the other end is connected to the transverse plate 31, which serves as a bridge for transmitting motion and force. As the wheel 21 rotates, the connecting rod drives the transverse plate 31 to reciprocate in the horizontal direction.

[0029] like Figures 1-4As shown, a second connecting rod 23 is fixed to the rear end of the wheel 21. The wheel 21 is movably connected to the support frame 11 through the second connecting rod 23. A synchronous wheel 24 is fixed to the rear end of the second connecting rod 23. The synchronous wheel 24 is fixed to the rear end of the connecting rod to realize the synchronous transmission of power and the precise control of the coordination of movement.

[0030] like Figures 1-4 As shown, the adsorption assembly 4 includes an adsorption base 41, which is fixed to the front end of the rotating rod 32. An extension rod 42 is fixed to the right side of the adsorption base 41, and a suction cup 44 is installed on the right side of the extension rod 42. The suction cup 44 is installed on the right side of the extension rod 42 and directly contacts the plastic cup to achieve the adsorption function.

[0031] like Figures 1-4 As shown, the extension rod 42 has a hollow structure. An air pressure interface 43 is provided on one side of the extension rod 42. Through this air pressure interface 43, an external air source can introduce negative pressure air into the hollow interior of the extension rod 42. This negative pressure air flows along the hollow channel to the suction cup 44 installed on the right side of the extension rod 42.

[0032] When using the plastic cup flipping device, first start the external power source, so that the wheel 21 starts to rotate in a circle under the drive of the external power source through the synchronous wheel 24. The first connecting rod 22 connected to the edge of the wheel 21 will move with the rotation of the wheel 21. Since the other end of the first connecting rod 22 is connected to the transverse plate 31, the first connecting rod 22 will drive the transverse plate 31 to move back and forth in the horizontal direction along the slide rail 111.

[0033] When the horizontal sliding plate 31 moves to the position of the plastic cup, the external air source introduces the negative pressure air source into the hollow interior of the extension rod 42 through the air pressure interface 43 on one side of the extension rod 42. The negative pressure air source flows along the hollow channel to the suction cup 44 installed on the right side of the extension rod 42, so that the suction cup 44 generates an adsorption force, thereby adsorbing the plastic cup.

[0034] The wheel 21 continues to rotate, driving the transverse plate 31 to the designated flipping position. During this process, the second bearing 34 on the connecting block 321 at the rear end of the rotating rod 32 moves within the V-shaped groove 121 in the middle of the support plate 12. Since the groove 121 is V-shaped, when the second bearing 34 slides to the bent section of the groove 121, the second bearing 34 drives the connecting block 321 to flip, thereby causing the adsorption assembly 4 to flip and flip the plastic cup. The groove 121 provides guidance and limit for the rotation of the rotating rod 32. After the plastic cup is flipped, the external air source stops supplying negative pressure air, the suction cup 44 loses its adsorption force, and the plastic cup is placed in the position required for subsequent operations, completing one plastic cup flipping operation.

[0035] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
