[0018] The utility model is further described below in conjunction with the drawings and examples. In the following detailed description, certain exemplary embodiments of the utility model are described by way of illustration only. It is needless to say that those skilled in the art can realize that the described embodiments can be modified in various ways without departing from the spirit and scope of the utility model. Therefore, the drawings and description are illustrative in nature and are not used to limit the protection scope of the claims.

[0019] As Figures 1 to 3 The utility model discloses a special equipment for bending arc of agricultural corrugated sheet, which comprises a frame 1, a first bending roller 2, a second bending roller 3 and a third bending roller 4 are arranged in parallel on the upper portion of the frame 1.

[0020] The first bending roller 2 is located above the second bending roller 3 and corresponds to the upper and lower positions, an entering plate gap is formed between the first bending roller 2 and the second bending roller 3, the third bending roller 4 is located at the rear side of the second bending roller 3, and the top end of the third bending roller 4 is higher than the entering plate gap, the roller shafts at the left and right ends of the first bending roller 2 are rotatably installed on the frame 1, the roller shafts at the left and right ends of the second bending roller 3 are rotatably installed on the frame 1, the roller shaft ends at the same end of the first bending roller 2 and the second bending roller 3 are connected through a gear or a chain wheel and a chain transmission, and the roller shaft end of the second bending roller 3 is further connected to a motor. The first bending roller 2 and the second bending roller 3 are used to drive the corrugated sheet to realize automatic feeding, after the corrugated sheet enters the entering plate gap between the first bending roller 2 and the second bending roller 3, the corrugated sheet is automatically conveyed under the action of the motor, when the corrugated sheet passes through the third bending roller 4, the third bending roller 4 upwardly pushes the corrugated sheet, so that the corrugated sheet is bent and deformed. In the embodiment, the first bending roller 2 and the second bending roller 3 are directly rotatably connected to the frame 1, the entering plate gap cannot be adjusted to adapt to corrugated sheets of different thicknesses, but if it is necessary to adjust the entering plate gap, the height of the first bending roller 2 can be adjusted, at this time, the roller shaft at the end of the first bending roller 2 is installed on a bearing support, and the bearing support is connected to the frame 1 through a screw rod lifting mechanism, which belongs to the prior art and will not be described here.

[0021] When the wave plate needs to be adjusted, the relative height of the third bending roller 4 to the plate gap can be changed, when the top of the third bending roller 4 is close to the plate gap, the greater the curvature radius of the wave plate after bending, the smaller the bending degree of the wave plate, when the third bending roller 4 is adjusted upwards, the height of the top of the third bending roller 4 is higher than the plate gap, the curvature radius of the wave plate after bending becomes smaller, and the bending degree of the wave plate becomes larger, as the third bending roller 4 is adjusted upwards, the curvature radius of the wave plate after bending gradually becomes smaller, and the bending degree of the wave plate gradually becomes larger.

[0022] Therefore, the installation mode of the third bending roller 4 is improved, and the position adjustment of the third bending roller 4 is realized by automatic control. The roller shafts at the left and right ends of the third bending roller 4 are rotatably installed on the adjusting support through bearings, the left and right ends of the adjusting support are slidably connected to the rack 1 through adjusting guide devices, the rack 1 is provided with a roller shaft through hole 5, the left and right roller shaft ends of the third bending roller 4 pass through the adjusting support and extend out of the rack 1 through the roller shaft through hole 5, one of the roller shaft ends is drivingly connected to the roller shaft end of the second bending roller 3, and the rack 1 is provided with an adjusting driving device for driving the adjusting support to slide and lift along the adjusting guide device. During adjustment, the adjusting driving device acts to pull the adjusting support to slide and lift along the adjusting guide device, so as to drive the third bending roller 4 to follow the lifting, change the relative height between the third bending roller 4 and the plate gap, and achieve the purpose of changing the bending curvature of the wave plate; when the position adjustment of the third bending roller 4 meets the requirements, the adjusting driving device stops acting to control the adjusting support to remain at this position.

[0023] The roller shaft through hole 5 can be a long hole, which is opened along the sliding direction of the third bending roller 4, during the lifting of the third bending roller 4, the roller shaft end can slide and lift along the roller shaft through hole 5, without affecting the power transmission of the roller shaft end, the roller shaft end of the third bending roller 4 and the roller shaft end of the second bending roller 3 are drivingly connected through a sprocket and a chain, and the tightness of the chain is adjusted through a tensioning wheel, so as to ensure that the position adjustment of the third bending roller 4 does not affect the power transmission between the second bending roller 3 and the third bending roller 4.

[0024] Referring to Figure 2 and Figure 4The adjusting support is used as the mounting base of the third bending roller 4, and comprises left and right adjusting side supports 6 and a side support connecting bottom plate 7 connecting the two adjusting side supports 6. The two end roller shafts of the third bending roller 4 are rotatably connected to the adjusting side supports 6 through bearings and extend out of the adjusting side supports 6. The third bending roller 4 can rotate relative to the adjusting side supports 6, and when the adjusting side supports 6 slide and lift, the third bending roller 4 can be lifted along with the adjusting side supports 6.

[0025] Referring to Figure 2 and Figure 4 The adjusting guiding device comprises a guiding slide base 8 fixed to the rack 1. The guiding slide base 8 is directly fixed to the rack 1 through bolts. The guiding slide base 8 is provided with a guiding slide groove. The adjusting side supports 6 are slidably mounted on the guiding slide base 8 along the guiding slide groove. The surface of the guiding slide base 8 is provided with a through hole corresponding to the roller shaft through hole 5, which is beneficial for the roller shaft end of the third bending roller 4 to pass through. The guiding slide groove on the guiding slide base 8 is used as the sliding limiting structure of the adjusting side supports 6, so that the adjusting side supports 6 can only slide and lift along the guiding slide groove.

[0026] Referring to Figure 2 and Figure 4 The adjusting driving device comprises an adjusting motor 9. The body of the adjusting motor 9 is fixed to the bottom end of the rack 1. The rotating power end of the adjusting motor 9 is upwardly arranged and fixed with an adjusting stud 10. The adjusting stud 10 is threadedly connected to the side support connecting bottom plate 7. During adjustment, the adjusting motor 9 drives the adjusting stud 10 to rotate, drives the side support connecting bottom plate 7 to lift along the adjusting stud 10, so that the adjusting side supports 6 slide and lift along the guiding slide groove.

[0027] Referring to Figure 3 and Figure 4 The guiding slide groove is arranged to be inclined from bottom to top and towards the first bending roller 2. The axis of the adjusting stud 10 is parallel to the direction of the guiding slide groove. At this time, the third bending roller 4 can slide and adjust along the inclined direction towards the first bending roller 2. Compared with the vertical sliding adjustment mode, the adjusting stud 10 can achieve the purpose of greater curvature adjustment by adjusting a smaller distance.
