Description

Technical Field

[0001] This utility model relates to the field of agricultural corrugated board processing, and in particular to a bending and arc processing equipment for long-specification agricultural corrugated boards. Background Technology

[0002] With industrial development, the demand for metal sheets is increasing, and the requirements for their shape are also becoming more stringent. Corrugated sheets, commonly used in agriculture, are typically used to form flower beds, roofs for sheds, garden greenhouses, and agricultural greenhouses. A bending machine is a device used to bend corrugated sheets into an arc shape. Existing bending machines have two main problems: First, agricultural corrugated sheets are generally quite wide, up to three meters, resulting in correspondingly long bending rollers. During bending, the corrugated sheet reacts against the roller surface, causing the center of the roller to bulge or sink, resulting in bending deformation and affecting the bending effect. Second, existing bending machines usually require adjustment of the bending roller's position to accommodate fine-tuning of the corrugated sheet's thickness and curvature. Current adjustment methods are complex, leading to high overall precision and cost. However, the precision requirements for corrugated sheets used in agriculture are not high. Therefore, it is necessary to design a bending machine that is simple in structure, easy to use, low in cost, and does not cause bending deformation. Summary of the Invention

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0019] like Figures 1 to 4 As shown, a long-specification agricultural corrugated board bending processing equipment includes a frame 1. A first bending roller 2, a second bending roller 3, and a third bending roller 4 are mounted parallel to each other on the top of the frame 1. The first bending roller 2 is located above the second bending roller 3 and their vertical positions correspond. A board entry gap is formed between the first bending roller 2 and the second bending roller 3. The third bending roller 4 is located behind the second bending roller 3, and its top end is higher than the board entry gap. The roller shaft ends of the first bending roller 2 and the second bending roller 3 are driven by a sprocket and a chain. The roller shaft ends of the second bending roller 3 and the third bending roller 4 are also driven by a sprocket and a chain. The second bending roller 3 is connected to a motor via a sprocket and a chain. The first curved roller 2 and the second curved roller 3 are used to drive the corrugated plate to achieve automatic feeding. After the corrugated plate enters through the gap between the two, it is automatically conveyed under the action of the motor. When the corrugated plate passes the third curved roller 4, the third curved roller 4 pushes the corrugated plate upward, causing the corrugated plate to bend and deform.

[0020] The first curved roller 2 has its two ends rotatably connected to the first support base 5, which is slidably mounted on the frame 1. The second curved roller 3 has its two ends rotatably connected to the frame 1. The third curved roller 4 has its two ends rotatably connected to the second support base 6, which is slidably mounted on the frame 1. Since the second curved roller 3 is directly rotatably connected to the frame 1, while the first curved roller 2 is slidably connected to the frame 1 via the first support base 5, the height of the first curved roller 2 can be adjusted upwards to adjust the infeed gap and accommodate corrugated boards of different thicknesses. Since the third curved roller 4 is slidably connected to the frame 1 via the second support base 6, the height of the second curved roller 3 can be adjusted upwards to adjust its relative height to the infeed gap, thereby adjusting the curvature of the corrugated board. When it is necessary to adjust the curvature of the corrugated plate, this can be achieved by changing the height of the third bending roller 4 relative to the gap between the inlet and the plate. When the top height of the third bending roller 4 is close to the gap between the inlet and the plate, the curvature radius of the corrugated plate after bending is larger and the degree of bending is smaller. When the third bending roller 4 is adjusted upward so that the top height of the third bending roller 4 is significantly higher than the gap between the inlet and the plate, the curvature radius of the corrugated plate after bending becomes smaller and the degree of bending increases. As the third bending roller 4 is adjusted upward, the curvature radius of the corrugated plate after bending gradually decreases and the degree of bending gradually increases.

[0021] The first curved roller 2 has its two ends rotatably connected to the first support base 5 via bearings. The first support base 5 is slidably mounted on the frame 1. The side of the frame 1 is provided with a limiting groove that allows the first support base 5 to slide only vertically. The limiting groove can be a dovetail groove. The first support base 5 cooperates with the dovetail groove, allowing it to slide only vertically, while the axial position of the first curved roller 2 remains unchanged. First lower pressure roller shafts 7 are respectively provided on the upper left and right sides of the first curved roller 2. The two first lower pressure roller shafts 7 are symmetrical about the length of the first curved roller 2. The two first lower pressure roller shafts 7 press the first curved roller 2 downwards, limiting the vertical position of the first curved roller 2. Before using the equipment, the position of the first curved roller 2 needs to be adjusted according to the thickness of the corrugated plate. First, the first support seats 5 at both ends of the first curved roller 2 are lifted with inclined shims to increase the width of the inlet gap. Then, the corrugated plate is passed through the inlet gap. Next, the inclined shims are gradually adjusted outward according to the thickness of the corrugated plate to gradually reduce the inlet gap so that the inlet gap is completely adapted to the thickness of the corrugated plate. Then, the first lower pressure roller shaft 7 is adjusted so that the first lower pressure roller shaft 7 contacts the surface of the first curved roller 2. The first lower pressure roller shaft 7 presses the first curved roller 2 downward. At this time, the first lower pressure roller shaft 7 acts as a limiting structure for positioning the first curved roller 2 downward, ensuring that the corrugated plate will not lift the first curved roller 2 upward and slide upward during the conveying process. In addition, the cooperation of the two first lower pressure roller shafts 7 can prevent the first curved roller 2 from bulging upward and deforming, thus achieving the purpose of preventing the first curved roller 2 from deforming.

[0022] After the position of the first curved roller 2 is adjusted, the tension of the chain between the first curved roller 2 and the second curved roller 3 is adjusted by the tensioning structure, and the transmission between the first curved roller 2 and the second curved roller 3 is not affected.

[0023] The first pressing roller shaft 7 includes a first roller shaft seat 71 fixed to the frame 1. First shaft seat uprights are respectively provided at the bottom of the left and right ends of the first roller shaft seat 71. Two first roller shafts 72 are rotatably mounted between the two first shaft seat uprights. The rotation axis of the first roller shaft 72 is parallel to the rotation axis of the first curved roller 2. The two first roller shafts 72 are arranged parallel to each other front-to-back and symmetrical about the front-to-back direction of the first curved roller 2. The two first roller shafts 72 simultaneously press against the surface of the first curved roller 2. The first roller shaft seat 71 is fixedly connected to the frame 1 by bolts and nuts. The height of the first pressing roller shaft 7 can be adjusted by adding or removing shims or multiple 1mm shims between the first roller shaft seat 71 and the frame 1, so that the two first curved rollers 2 can simultaneously press against the surface of the first curved roller 2, achieving a stable and limited position.

[0024] The two ends of the roller shaft of the second bending roller 3 are rotatably connected to the frame 1 through bearings. The two ends of the roller shaft of the second bending roller 3 are rotatably connected to the frame 1. A second upper support roller shaft 8 is provided in the lower middle part of the second bending roller 3. The second upper support roller shaft 8 presses the second bending roller 3 upward and supports the second bending roller 3 to prevent the middle part of the second bending roller 3 from being concave and deformed downward. The second bending roller 3 is provided between the two first bending rollers 2. The first bending rollers 2 and the second bending roller 3 are staggered to achieve a better anti-bending purpose in a simple way.

[0025] The second upper roller shaft 8 includes a second roller shaft seat 81 fixed on the frame 1. The top of the left and right ends of the second roller shaft seat 81 are respectively provided with second shaft seat upright plates. Two second roller shafts 82 are rotatably installed between the two second shaft seat upright plates. The rotation axis of the second roller shaft 82 is parallel to the rotation axis of the second curved roller 3. The two second roller shafts 82 are arranged in parallel front and rear and symmetrical about the front and rear direction of the second curved roller 3. The two second roller shafts 82 press on the surface of the second curved roller 3 at the same time.

[0026] The two ends of the roller shaft of the third curved roller 4 are rotatably connected to the second support seat 6 via bearings. The second support seat 6 is slidably mounted on the frame 1. The side of the frame 1 is provided with a limiting groove that allows the second support seat 6 to slide only vertically. The limiting groove can be a dovetail groove. The second support seat 6 cooperates with the dovetail groove and can only slide vertically, while the axial position of the third curved roller 4 remains unchanged. The lower left and right sides of the third curved roller 4 are respectively provided with third upper roller shafts 9. The two third upper roller shafts 9 are symmetrical about the length of the third curved roller 4. The two third upper roller shafts 9 press the third curved roller 4 upward, and the vertical position of the third curved roller 4 is limited by the third upper roller shafts 9. Before using the equipment, the position of the third curved roller 4 needs to be adjusted according to the required curvature of the corrugated plate. By adjusting the third upper roller shaft 9, the third upper roller shaft 9 is made to contact the surface of the third curved roller 4, and the third upper roller shaft 9 presses the third curved roller 4 upward. At this time, the third upper roller shaft 9 acts as a limiting structure for positioning the third curved roller 4 upward, ensuring that the corrugated plate will not press the third curved roller 4 downward and slide during the conveying process. In addition, the two first lower pressure roller shafts 7 cooperate to prevent the third curved roller 4 from concave and deforming downward, thereby achieving the purpose of preventing the third curved roller 4 from deforming.

[0027] After the position of the third curved roller 4 is adjusted, the tension of the chain between the third curved roller 4 and the second curved roller 3 is adjusted by the tensioning structure, and the transmission between the third curved roller 4 and the second curved roller 3 is not affected.

[0028] The third upper roller shaft 9 includes a third roller shaft seat 91 fixed to the frame 1. Third shaft seat uprights are respectively provided at the top of the left and right ends of the third roller shaft seat 91. Two third roller shafts 92 are rotatably mounted between the two third shaft seat uprights. The rotation axis of the third roller shaft 92 is parallel to the rotation axis of the third curved roller 4. The two third roller shafts 92 are arranged parallel to each other front-to-back and symmetrical about the front-to-back direction of the third curved roller 4. The two third roller shafts 92 simultaneously press against the surface of the third curved roller 4. The third roller shaft seat 91 is fixedly connected to the frame 1 by bolts and nuts. The height of the third upper roller shaft 9 can be adjusted by adding or removing shims or multiple 1mm shims between the third roller shaft seat 91 and the frame 1, so that the two third curved roller shafts can simultaneously press against the surface of the third curved roller 4, achieving a stable and limited position.
