Abstract
Description
Technical Field
[0001] This invention relates to the field of pulp feeding machine technology, specifically to an automatic pulp feeding mechanism for a feeding machine. Background Technology
[0002] Pulp feeding machines are common automated equipment in industrial production, widely used in industries such as building materials, papermaking, and furniture manufacturing. They are mainly used for the automatic conveying and feeding of sheet-like or pulp-like materials. In traditional production processes, the feeding of sheet-like or pulp-like materials often relies on manual or semi-mechanical methods, resulting in high labor intensity, low efficiency, and poor consistency. Especially in large-scale, automated production lines, achieving accurate, continuous, and single-sheet (or single-block) feeding of materials has become a key factor affecting overall production efficiency and product quality.
[0003] Currently, most slurry feeding mechanisms on the market employ pneumatic or mechanical pusher structures, using push plates to push materials one by one to designated workstations. However, these devices still have several shortcomings in actual use. First, due to factors such as the flatness, thickness, or viscosity of the material surface, two or more sheets can easily be pushed simultaneously during the feeding process, leading to errors in subsequent workstations (such as robotic arms or suction cups), affecting production rhythm, and even causing equipment downtime. Second, traditional pusher mechanisms lack effective clamping and limiting mechanisms during the feeding process, making it easy for materials to deviate, tilt, or jam, further reducing the reliability and accuracy of feeding. Summary of the Invention
[0004] To address the shortcomings of existing technologies, this invention provides an automatic slurry feeding mechanism for a feeding machine. This solves the problem that existing slurry feeding mechanisms often employ pneumatic or mechanical pusher structures, using push plates to push materials one by one to designated workstations. However, such equipment still has several shortcomings in practical use. First, due to factors such as the flatness, thickness, or viscosity of the material surface, multiple sheets are easily pushed simultaneously during the feeding process, leading to errors in subsequent workstations (such as robotic arms or suction cups), affecting production rhythm, and even causing equipment downtime. Second, traditional pusher mechanisms lack effective clamping and limiting mechanisms during the feeding process, making it easy for materials to deviate, tilt, or jam, further reducing the reliability and accuracy of the feeding process.
[0005] To achieve the above objectives, the present invention provides the following technical solution: an automatic slurry feeding mechanism for a feeding machine, comprising a mounting plate, a flipping plate hinged to the lower wall of the mounting plate, a cylinder hinged to the front wall of the flipping plate, a sliding assembly provided on the upper wall of the flipping plate, the sliding assembly being telescopically connected to the cylinder, a push plate fixedly mounted on the sliding assembly, notches provided on both sides of the flipping plate and the sliding assembly, a pressing assembly provided on one side of the notch on the flipping plate, and a limiting assembly provided between the flipping plate and the mounting plate.
[0006] Preferably, the sliding assembly includes a pair of slide rails, a pair of sliders fixedly mounted on the upper wall of the flip plate, sliders slidably mounted on the slide rails, a movable plate fixedly mounted between the sliders, one end of the movable plate protruding from the flip plate, a push plate fixedly mounted on the lower wall of the protruding end of the movable plate, a limit rod fixedly mounted on the upper wall of the movable plate, a support frame fixedly mounted on the flip plate and located on one side of the slide rails, a crossbar rotatably mounted between the support frames, a rotating rod fixedly mounted on the crossbar, an elongated hole opened on the end of the rotating rod near the limit rod, the limit rod slidably mounted in the elongated hole, a first U-shaped block fixedly mounted on the telescopic end of the cylinder, and the end of the rotating rod near the cylinder hinged to the first U-shaped block.
[0007] Preferably, the clamping assembly includes a pair of hinges, one end of which is fixedly mounted on the flip plate and located on one side of the notch, and the other end of which is fixedly mounted with a Z-shaped plate. The vertical end and the horizontal end of the Z-shaped plate are exposed outside the notch, and a pair of mounting blocks are fixedly mounted on the lower wall of the horizontal end of the Z-shaped plate. Rollers are rotatably mounted between the mounting blocks.
[0008] Preferably, the limiting component includes an ear plate, which is fixedly installed on the lower wall of the mounting plate. A support plate is fixedly installed between the ear plate and the mounting plate. A T-shaped opening is provided on the flip plate below the ear plate. The ear plate and the support plate pass through the T-shaped opening respectively. A limiting plate is fixedly installed between the side wall of the ear plate and the lower wall of the support plate.
[0009] Preferably, the support plate has a triangular structure.
[0010] Preferably, a horizontal plate is fixedly installed on the rear wall of the mounting plate, a pair of second U-shaped blocks are fixedly installed on the lower wall of the horizontal plate, and a connecting plate is fixedly installed on the flip plate and below the second U-shaped blocks, the connecting plate being rotatably installed inside the second U-shaped blocks.
[0011] Preferably, reinforcing ribs are fixedly installed on the front wall of the mounting plate on both sides of the cylinder.
[0012] Beneficial effects This invention provides an automatic slurry feeding mechanism for a feeding machine, which has the following advantages: 1. This invention achieves precise pushing and positioning of slurry materials through the synergistic action of a sliding component, a pressing component, and a limiting component. The coordinated design of the slide rail, slider, moving plate, and rotating rod in the sliding component ensures smooth movement and controllable trajectory of the pusher plate during pushing, effectively preventing material deviation or jamming. The Z-shaped plate and roller structure in the pressing component apply appropriate pressure to the material surface during pushing, preventing material displacement due to vibration or inertia, and avoiding surface damage caused by excessive pressure. This is particularly suitable for slabs requiring high surface flatness or easily damaged slurries. The limiting component, through the cooperation of the T-shaped opening and the limiting plate, precisely controls the flipping angle of the tilting plate, ensuring that the tilting plate accurately stops in a horizontal working position each time material is fed, further improving the consistency and reliability of feeding.
[0013] 2. Traditional feeding mechanisms often result in multiple sheets being pushed at once due to material adsorption or adhesion, severely impacting subsequent processes. This invention separates the flipping action of the tilting plate from the pushing action of the pusher plate. In the first stage, after the tilting plate is horizontally positioned, the rollers of the clamping component first contact and press down on the top layer of material, achieving physical isolation of the lower layers. In the second stage, during the pusher plate's advancement, only the topmost single sheet is pushed out with the assistance of the rollers, effectively avoiding the occurrence of "double sheets" or "multiple sheets," greatly improving the feeding success rate. This is particularly suitable for thin sheets, films, or viscous pulp materials.
[0014] 3. This invention uses a cylinder as the core power source, featuring a simple structure, convenient control, and fast response speed. It can be efficiently integrated with the main control system of the production line to achieve fully automated cyclic operation. The entire feeding process, including flipping, pressing, pushing, and resetting, is completed in one smooth motion without manual intervention, significantly reducing labor intensity and increasing production cycle time. Simultaneously, the rational mechanism design and smooth operation reduce downtime caused by material jamming or malfunctions, improving overall equipment operating efficiency.
[0015] 4. This invention employs reinforcing ribs and triangular support plates in multiple locations to enhance the rigidity and stability of load-bearing components such as the mounting plate and flipping plate, thereby extending the equipment's service life. The slide rails and sliders in the sliding assembly are standard parts, facilitating procurement and replacement and reducing maintenance costs. The rollers in the clamping assembly are rotary-mounted, resulting in minimal wear, and can be adapted to different material characteristics by replacing rollers of different materials or specifications, making it highly practical.
[0016] This invention effectively solves the problems of inaccurate pushing, multiple sheet misfeeding, and low reliability of existing slurry feeding mechanisms through innovative mechanical structure design and multi-component collaborative working mechanism, and achieves efficient, accurate and reliable automated feeding, with good prospects for industrial application.

[0026] In this embodiment, the clamping assembly includes a pair of hinges 15. One end of each hinge 15 is fixedly mounted on the flip plate 2 and located on one side of the notch 5. The other end of each hinge 15 is fixedly mounted with a Z-shaped plate 16. The vertical end and the horizontal end of the Z-shaped plate 16 are exposed outside the notch 5. A pair of mounting blocks 17 are fixedly mounted on the lower wall of the horizontal end of the Z-shaped plate 16. A roller 18 is rotatably mounted between the mounting blocks 17.
[0027] In this embodiment, the limiting component includes an ear plate 19, which is fixedly installed on the lower wall of the mounting plate 1. A support plate 20 is fixedly installed between the ear plate 19 and the mounting plate 1. A T-shaped opening 21 is provided on the flipping plate 2 below the ear plate 19. The ear plate 19 and the support plate 20 pass through the T-shaped opening 21 respectively. A limiting plate 22 is fixedly installed between the side wall of the ear plate 19 and the lower wall of the support plate 20.
[0028] In this embodiment, the support plate 20 is further configured to have a triangular structure.
[0029] In this embodiment, a horizontal plate 23 is fixedly installed on the rear wall of the mounting plate 1, a pair of second U-shaped blocks 24 are fixedly installed on the lower wall of the horizontal plate 23, and a connecting plate 25 is fixedly installed on the flipping plate 2 and below the second U-shaped blocks 24. The connecting plate 25 is rotatably installed inside the second U-shaped blocks 24.
[0030] In this embodiment, reinforcing ribs 26 are fixedly installed on the front wall of the mounting plate 1 and on both sides of the cylinder 3.
[0031] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.
[0032] Example: As shown in the accompanying drawings, during use, the cylinder 3 is in the retracted state when its extension end is in operation. When material needs to be fed, the cylinder 3 is activated, and the extension end of the cylinder 3 pushes the first U-shaped block 14, which in turn pushes the rotating rod 12. The rotating rod 12 pushes the moving plate 8, which in turn pushes the flipping plate 2. At this time, the flipping plate 2 rotates within the second U-shaped block 24 under the action of the connecting plate 25 until the flipping plate 2 is in a horizontal state. The limiting plate 22 prevents the flipping plate 2 from over-flipping. At this time, the roller 18 contacts the surface of the material, pressing down on the material. Then, the extension end of the cylinder 3 continues to extend, pushing the rotating rod 12. The rotating rod 12, under the action of the crossbar 11, advances... As the rotating plate 8 rotates, the limiting rod 9 on the moving plate 8 is slidably installed in the elongated hole 13 of the rotating rod 12. When the rotating rod 12 rotates, the rotating rod 12 pushes the limiting rod 9 to move, which in turn pushes the moving plate 8. The moving plate 8 moves along the path of the slide rail 6 under the action of the slider 7, which in turn drives the push plate 4 to push the material. At this time, the material is pushed by the push plate 4 and moves under the action of the roller 18. After the material is fed, the telescopic end of the retraction cylinder 3 is retracted, which in turn retracts the flipping plate 2. In summary, the slurry feeder can feed one material at a time, and the gripping suction cup of the slurry feeder can only grip one at a time, preventing the error of gripping multiple materials at once.
