[0034] This embodiment provides a pressing mechanism, such as Figures 1-2As shown, the pressing mechanism includes a frame 1, a pneumatic power assembly 2, a transmission assembly 3, a linkage transmission assembly 4, and a pressing component 5. The pneumatic power assembly 2 is fixed on the frame 1 and has a first air port and a second air port, both of which can output high-pressure gas. The transmission assembly 3 includes a first transmission pipe 31 and a second transmission pipe 32. The first end of the first transmission pipe 31 is connected to the first air port, and the first end of the second transmission pipe 32 is connected to the second air port. The linkage transmission assembly 4 includes a cylinder 41 and a transmission rod 42. Cylinder 41 is fixed on frame 1. Cylinder 41 has a rodless chamber and a rod chamber. The second end of the first transmission pipe 31 is connected to the rodless chamber and can drive the piston rod in cylinder 41 to move in the forward direction along its axial direction. The second end of the second transmission pipe 32 is connected to the rod chamber and can drive the piston rod to move in the reverse direction along its axial direction. Transmission rod 42 is connected to piston rod. The movement of piston rod can drive transmission rod 42 to move synchronously. Pressing member 5 is connected to transmission rod 42. The movement of transmission rod 42 can drive pressing member 5 to move synchronously so that pressing member 5 presses the workpiece to be pressed.
[0035] The pressing mechanism disclosed in this embodiment operates as follows: During the pressing stage of the pressing component 5, high-pressure gas output from the first vent enters the rodless chamber of the cylinder 41 via the first transmission pipe 31, driving the piston rod to move forward along the piston rod axial direction, and consequently, the pressing component 5 to move forward along the piston rod axial direction, applying pressure to the component to be pressed. High-pressure gas output from the second vent enters the rod chamber of the cylinder 41 via the second transmission pipe 32, driving the piston rod to move in the opposite direction along the piston rod axial direction, and consequently, the pressing component 5 to move in the opposite direction along the piston rod axial direction, preventing the pressing component 5 from falling rapidly due to its own weight and ensuring the stability of the pressing process. During the return stage of the pressing component 5, high-pressure gas output from the second vent enters the rod chamber of the cylinder 41 via the second transmission pipe 32, driving the piston rod to move, thereby smoothly resetting the pressing component 5. This pressing mechanism can precisely adjust the pressing force and movement speed, significantly improving recycling efficiency and quality.
[0036] In this embodiment, the rodless chamber of cylinder 41 is defined as the cavity within cylinder 41 that does not contain the piston rod, which is the space on one side of the piston; the rod chamber of cylinder 41 is the cavity that contains the piston rod, which is the space on the other side of the piston.
[0037] Taking cardboard boxes as an example, during the cardboard box recycling process, when removing the tape used for sealing the cardboard box, the tape sticks to the cardboard box, making separation difficult. Manual disassembly is inefficient and easily damages the cardboard box, affecting the recycling quality. At the same time, tape residue remains on the equipment surface or inside the cardboard box, increasing the frequency of equipment cleaning and maintenance costs. This consumes a lot of manpower and resources and seriously affects production efficiency and the continuity of the recycling process.
[0038] Using the pressing mechanism in this embodiment, a cardboard box with tape is placed at a designated position below the pressing component 5. The pneumatic power assembly 2 outputs high-pressure gas through the first air port, which enters the rodless chamber of the cylinder 41 through the first transmission pipe 31, driving the piston rod to move the pressing component 5 in the forward axial direction. The second air port outputs high-pressure gas, which enters the rod chamber of the cylinder 41 through the second transmission pipe 32, driving the piston rod to move the pressing component 5 in the reverse axial direction of the piston rod. This prevents the pressing component 5 from falling rapidly due to its own weight, applying stable pressure to the surface of the cardboard box, causing the tape to separate from the tightly adhered portion of the cardboard box. By precisely controlling the air pressure and piston rod movement, the pressing force and movement speed are precisely adjusted to prevent damage to the cardboard box. The pressing mechanism effectively separates the cardboard box from the tape on it, significantly improving the recycling efficiency and quality of paper materials.
[0039] In this embodiment, the linkage transmission assembly 4 also includes a fixing member 43, which is fixed on the frame 1, and the cylinder 41 is fixed on the fixing member 43.
[0040] Optionally, the pneumatic power component 2 can be an air compressor, a gas booster pump, a high-pressure air tank, etc., without specific limitations.
[0041] In other embodiments, the pneumatic power assembly 2 can be replaced with a hydraulic power assembly. During operation, the hydraulic pump draws hydraulic oil from the oil tank and pressurizes it. After being regulated by the control valve group, the high-pressure oil enters the rodless or rod chamber of the cylinder 41 through the pipeline of the transmission assembly 3. During the pressing stage, the high-pressure oil enters the rodless chamber, driving the piston rod to move the pressing component 5 in the forward direction to press the component to be pressed. During the return stage, the oil enters the rod chamber, causing the pressing component 5 to reset. No specific limitation is made here.
[0042] like Figures 1-2 As shown, the first and second air holes are on the same plane. Because the two air holes are on the same plane, the difference in path length between the high-pressure gas from the first air hole through the first transmission pipe 31 to the rodless chamber of the cylinder 41 and from the second air hole through the second transmission pipe 32 to the rod chamber of the cylinder 41 is minimized, reducing pressure loss caused by the different air path distances.
[0043] In this embodiment, a first pressure regulating valve (not shown) is provided on the first transmission pipe 31, which can precisely control the gas pressure entering the rodless chamber of the cylinder 41. The first pressure regulating valve can stabilize pressure fluctuations and ensure smooth piston rod movement. In this embodiment, a second pressure regulating valve (not shown) is provided on the second transmission pipe 32, which can precisely regulate the gas pressure entering the rod chamber of the cylinder 41. The second pressure regulating valve can balance the pressure during the pressing stage and the return stage, enhancing system stability.
[0044] In other embodiments, a first pressure regulating valve may be provided only on the first transmission pipe 31 or a second pressure regulating valve may be provided on the second transmission pipe 32; no specific limitation is made here.
[0045] like Figure 1 As shown, the pressing mechanism also includes a conveying assembly 6, which is mounted on the frame 1. The conveying assembly 6 can hold the workpiece to be pressed and is used to drive the workpiece to be pressed horizontally. The pressing component 5 is vertically positioned above the conveying assembly 6 and can move vertically, with the horizontal and vertical directions perpendicular to each other. The conveying assembly 6 allows the workpiece to be pressed to move horizontally. The cooperation between the conveying assembly 6 and the vertically moving pressing component 5 enables automated continuous pressing operations. The pressing process is stable and efficient, ensuring accurate pressing position, avoiding deviation or jamming, and reducing manual intervention.
[0046] In this embodiment, for ease of description, the axial direction of the piston rod is vertical. The positive direction of the piston rod axial direction is the downward pressing direction, and the negative direction of the piston rod axial direction is the upward return direction.
[0047] like Figure 1 As shown, the conveying assembly 6 includes a drive motor and multiple transmission rollers. These rollers are rotatably mounted on the frame 1 and are evenly spaced horizontally. The upper surfaces of the rollers are flush, allowing them to support the workpiece to be pressed. The output of the drive motor is connected to the transmission rollers, enabling the motor to drive them to rotate synchronously, thus moving the workpiece horizontally. On one hand, the evenly spaced horizontal arrangement and flush upper surfaces of the rollers stably support the workpiece, ensuring it remains horizontal during transport and preventing tilting or swaying that could affect the pressing effect. On the other hand, the drive motor precisely controls the rotation of the rollers, achieving uniform and stable transport of the workpiece, precisely coordinating with the movement of the pressing component 5 to improve the pressing position accuracy. Specifically, the drive motor can be connected to a drive shaft via a reducer, and the drive shaft then distributes power to each transmission roller via a chain.
[0048] In other embodiments, the conveying assembly 6 includes a drive motor, two synchronous pulleys and a conveyor belt. The conveyor belt is wound around the outer periphery of the two synchronous pulleys and is tensioned by the two synchronous pulleys. The drive motor is connected to one of the two synchronous pulleys. The drive motor can drive the synchronous pulley to rotate and can drive the conveyor belt to move in order to convey the parts to be pressed. The type of the conveying assembly 6 is not specifically limited here.
[0049] In this embodiment, the pressing mechanism also includes a position detection component, which is communicatively connected to the pneumatic power assembly 2. The position detection component is used to monitor the position of the part to be pressed relative to the pressing component 5. The position detection component, communicatively connected to the pneumatic power assembly 2, can provide real-time feedback on the position information of the part to be pressed relative to the pressing component 5. When the part to be pressed reaches the preset pressing position, the position detection component immediately sends a signal to the pneumatic power assembly 2, precisely controlling the output of high-pressure gas from the first or second air port, driving the pressing component 5 to promptly initiate pressing or return actions, achieving automated and precise operation. This linkage mechanism avoids time errors and positional deviations that may occur due to manual intervention, significantly improving pressing accuracy and efficiency. Simultaneously, during continuous operation, by monitoring the position of the part to be pressed in real time, the pneumatic power assembly 2 can dynamically adjust the output pressure and gas flow rate to adapt to the pressing requirements of parts of different specifications, further improving operational stability and product quality, and reducing equipment wear and maintenance costs.
[0050] In this embodiment, the pressing component 5 is made of polyoxymethylene (POM). POM has high hardness and strong wear resistance, which can withstand the frictional wear of frequent pressing operations and extend the service life of the component. At the same time, POM has good rigidity and dimensional stability, which can ensure that the pressing surface of the pressing component 5 facing the part to be pressed always remains flat, so that the part to be pressed is subjected to uniform force, thereby improving the pressing accuracy and quality.
[0051] In this embodiment, the surface of the pressing component 5 is provided with anti-slip texture. On the one hand, the anti-slip texture can significantly increase the friction between the pressing component 5 and the part to be pressed, preventing the part to be pressed from sliding and shifting during pressing, ensuring accurate pressing position, and reducing the cost of repeated operations caused by displacement. On the other hand, the texture design can disperse local pressure, preventing the pressing component 5 from directly pressing the surface of the part to be pressed and causing damage, while enhancing the adaptability to parts to be pressed made of different materials.
[0052] In this embodiment, the edges of the pressing component 5 are rounded. This avoids sharp edges from scratching or damaging the surface of the component to be pressed, and is especially suitable for fragile materials such as cardboard boxes, thus improving the pressing quality.
[0053] In this embodiment, both the first transmission pipe 31 and the second transmission pipe 32 are flexible hoses. They possess good flexibility, allowing for easy bending without damage. The hose material is typically high-pressure resistant and wear-resistant, enabling stable transmission of gas or liquid media. They can buffer vibrations and impacts during system operation, reduce stress loss at pipe connections, and extend service life. Furthermore, flexible hoses are easy to install and highly replaceable; when a localized breakage occurs, the entire hose does not need to be replaced, reducing maintenance costs.
[0054] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
