[0001] This utility model relates to the field of corrugated paper production, specifically a stacking and transfer device for corrugated paper production. Background Technology

[0002] Corrugated paper is a composite material made of at least one layer of corrugated core paper (corrugated paper) and one or more layers of flat cardboard (linerboard). It is lightweight, durable, and cost-effective. Its unique corrugated structure effectively disperses external forces, providing excellent cushioning and compression resistance, and is widely used in packaging, such as for cartons and liners. Its strength and thickness can be adjusted according to the corrugated shape and number of layers to meet different needs. Furthermore, corrugated paper is environmentally friendly and recyclable, making it a sustainable alternative to plastic packaging and playing an important role in industries such as logistics, e-commerce, and food.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please refer to Figures 1-4. One embodiment of this utility model provides a stacking and transferring device for corrugated paper production, including a flatbed cart 1. Side baffles 105 are fixedly connected to both the front and rear ends of the middle section of one side of the upper end of the flatbed cart 1. During loading, corrugated paper is placed one by one on the upper end of the flatbed cart 1, with one side of the corrugated paper adhering to the side baffle 105 for alignment. Side fixing plates 101 are fixedly connected to both sides of the front and rear ends of the flatbed cart 1. Guide rods 102 are fixedly connected between the two side fixing plates 101 at the front and rear ends of the flatbed cart 1. A C-shaped movable frame 2 is provided on the upper end of the flatbed cart 1. The lower end of the C-shaped movable frame 2... Guide sliders 201 are fixedly connected to both ends of the flatbed 1. The two guide sliders 201 are inserted between the two side fixing plates 101 at the front and rear ends of the flatbed 1, respectively. The two guide rods 102 pass through the middle of the two guide sliders 201. Side protective plates 103 are fixedly connected to the outer side of the two side fixing plates 101 at the front and rear ends of the flatbed 1. After the corrugated paper is stacked on the flatbed 1, the C-shaped movable frame 2 moves to the middle of the upper end of the stacked corrugated paper by moving along the guide rods 102 through the two guide sliders 201. A pull rod 104 is fixedly connected to the upper end of the flatbed 1 and to the outer side of the side baffle 105.

[0024] Please refer to Figures 2 and 3. Alignment push plates 4 are connected to both the front and rear ends of the inner side of the C-shaped movable frame 2. Second hydraulic rods 205 are fixedly connected to the middle of both the front and rear ends of the C-shaped movable frame 2. The telescopic ends of the two second hydraulic rods 205 pass through the middle of the front and rear end faces of the C-shaped movable frame 2 and are fixedly connected to the middle of the outer end faces of the two alignment push plates 4, respectively. Second guide tubes 206 are fixedly connected to the upper and lower ends of the middle of the front and rear end faces of the C-shaped movable frame 2. Second guide rods 401 are fixedly connected to the upper and lower ends of the outer end faces of the two alignment push plates 4. The two second guide rods 401 on the two alignment push plates 4 pass through the interior of the two second guide tubes 206 at the front and rear ends of the C-shaped movable frame 2, respectively. The two second hydraulic rods 205 push the two alignment push plates 4 to move relative to each other, causing the two alignment push plates 4 to clamp the front and rear ends of the stacked corrugated paper, aligning the front and rear ends of the stacked corrugated paper. When the alignment push plates 4 move, they are guided by the sliding of the second guide rods 401 along the interior of the second guide tubes 206, ensuring the stability of the movement of the alignment push plates 4.

[0025] Please refer to Figures 2 and 3, and Figures 1-4. A first hydraulic rod 202 is fixedly connected to the middle of the upper end of the C-shaped movable frame 2. A pressure plate 3 is connected to the upper inner side of the C-shaped movable frame 2. The telescopic end of the lower end of the first hydraulic rod 202 passes through the middle of the upper end of the C-shaped movable frame 2 and is fixedly connected to the middle of the upper end of the pressure plate 3. Fixing blocks 203 are fixedly connected to the middle of the upper ends of both sides of the C-shaped movable frame 2. A first guide tube 204 is fixedly connected to the middle of each of the two fixing blocks 203. A first guide rod 301 is fixedly connected to both sides of the middle of the upper end of the pressure plate 3. The upper ends of the two first guide rods 301 pass through the interior of the two first guide tubes 204 and extend out of the upper end of the C-shaped movable frame 2. After the stacked corrugated paper is aligned by the alignment pusher plate 4, the first hydraulic rod 202 pushes the pressing plate 3 down, causing the pressing plate 3 to descend and press the top of the stacked corrugated paper, thus pressing the stacked corrugated paper to prevent the corrugated paper stack from shaking and tipping over due to the movement of the flatbed trolley 1. When unloading, the first hydraulic rod 202 and the second hydraulic rod 205 retract synchronously, and the C-shaped movable frame 2 is pushed by the guide slider 201 to move the C-shaped movable frame 2 to one side of the upper side baffle 105 of the flatbed trolley 1, so that the stacked corrugated paper can be unloaded from different directions on the upper part of the flatbed trolley 1, improving the convenience of unloading.

[0026] Working Principle: In use, corrugated paper is first stacked layer by layer on the top of the flatbed trolley 1, ensuring one side of the corrugated paper is tightly against the side baffle 105 for initial alignment. After stacking, the C-shaped movable frame 2 is pushed along the guide rod 102 to the center of the corrugated paper stack. Two second hydraulic rods 205 are activated, pushing two alignment push plates 4 to move relative to each other. Guided by the second guide rod 401 within the second guide tube 206, the push plates smoothly clamp the front and rear ends of the corrugated paper stack, achieving precise alignment. Subsequently, the first hydraulic rod 202 pushes the pressing plate 3 downwards. Guided by the first guide rod 301 within the first guide tube 204, vertical pressure is ensured, firmly pressing the corrugated paper stack. During transport, the pressing and alignment mechanism effectively prevents the paper stack from shaking or tipping over. Upon arrival at the destination, the first hydraulic rod 202 and the second hydraulic rod 205 are retracted to release the clamping and alignment. Then, the C-shaped movable frame 2 is pushed back to the side of the side baffle 105, allowing for flexible unloading from the three open sides of the flatbed truck 1, which significantly improves loading and unloading efficiency and ease of operation.
