DETAILED DESCRIPTION

[0042] It is easy to understand that according to the technical solution of the present invention, without changing the essential spirit of the present invention, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific embodiments and drawings are only exemplary descriptions of the technical solution of the present invention and should not be regarded as the entire invention or as a limitation or restriction of the technical solution of the present invention.

[0043] like Figure 1-3 As shown, an overpass type flipping and unloading device includes a support frame 10, a fixed conveyor roller 20, a belt conveyor roller 30, an overpass flipping mechanism 40 and a unloading roller 50. The support frame 10 is provided with an overpass flipping mechanism 40 that can be adjusted up and down. The fixed conveyor roller 20 and the belt conveyor roller 30 are alternately provided on one side of the overpass flipping mechanism 40 on the support frame 10. The unloading roller 50 is provided on the other side of the overpass flipping mechanism 40 on the support frame 10.

[0044] The belt conveyor roller 30 and the lower sheet roller 50 convey in the same direction, and the conveying direction of the fixed conveyor roller 20 is perpendicular to the conveying direction of the belt conveyor roller 30;

[0045] State 1: The belt conveyor roller 30 is located below the fixed conveyor roller 20, and the fixed conveyor roller 20 is conveying materials;

[0046] When the material does not need to be turned over, the fixed conveyor roller 20 continues to convey the material until it is conveyed to the next processing step;

[0047] When the material needs to be turned over, the fixed conveyor roller 20 stops and the overpass turning mechanism 40 turns the material over until the material is turned over to the lower roller 50. In this way, it is suitable for the case where the belt conveyor roller 30 is damaged and cannot be used, and the material that needs to be turned over can still be turned over, avoiding the situation where the material cannot be turned over, and the actual application effect is better;

[0048] State 2: The belt conveyor roller 30 lifts the material above the fixed conveyor roller 20, and the belt conveyor roller 30 and the lower sheet roller 50 are in the same plane;

[0049] When the material does not need to be turned over, a space for the material to pass through is reserved in the middle position of the overpass turning mechanism 40, and the belt conveyor roller 30 conveys the material through the overpass turning mechanism 40 and conveys it to the lower roller 50. At this time, the overpass turning mechanism 40 does not rotate, and the space in the overpass turning mechanism 40 is arranged parallel to the belt conveyor roller 30 and the lower roller 50, so that the belt conveyor roller 30 can pass the material through the overpass turning mechanism 40. In this way, the conveying direction of the material can be changed, so that different processing steps can be performed on different types of materials.

[0050] When the material needs to be turned over, the overpass turning mechanism 40 turns the material over until the material is turned over to the lower roller 50;

[0051] Specifically, the material is lifted to a position parallel to the lower sheet roller 50 by the belt conveyor roller 30, and a group of clamping plates 43 on the overpass turning mechanism 40 clamp the material. The rotation of the clamping plates 43 can drive the material to rotate.

[0052] When the material is lifted by the belt conveyor roller 30, a gap is left in the middle of the belt conveyor roller 30, and the position of the gap corresponds to the top surface of the fixed conveyor roller 20. Therefore, when the overpass turning mechanism 40 turns over the material on the belt conveyor roller 30, the fixed conveyor roller 20 can still carry out the conveying operation for the material, thereby not affecting the conveying of the material by the fixed conveyor roller 20, and the actual application effect is better.

[0053] like Figure 4-5 As shown, the interchange flip mechanism 40 includes two parallel fixed rods 41, with T-shaped plates 44 fixed at both ends of the fixed rods 41. A drive motor 45 is provided on one side of the T-shaped plate 44 to drive the rotation thereof. An arc-shaped fixed disk 42 is fixed to the fixed rods 41, and an arc-shaped notch is formed in the arc-shaped fixed disk 42. At least two sets of clamping plates 43 are provided inside the notch on the arc-shaped fixed disk 42.

[0054] When the overpass turning mechanism 40 turns over the material on the fixed conveyor roller 20, at least one set of clamping plates 43 rotates to the position of the fixed conveyor roller 20, and the lower side plate of the set of clamping plates 43 is arranged parallel to the fixed conveyor roller 20;

[0055] When the overpass turning mechanism 40 turns over the material on the belt conveyor roller 30, at least one set of clamping plates 43 rotates to the position of the belt conveyor roller 30, and the lower side plate of the set of clamping plates 43 is arranged parallel to the belt conveyor roller 30;

[0056] The overpass turning mechanism 40 with this structure and the different groups of clamping plates 43 in the overpass turning mechanism 40 can be used to turn over materials on the fixed conveyor roller 20 on the one hand, and on the belt conveyor roller 30 on the other hand, so that the clamping plates 43 can better hold the materials, and the overpass turning mechanism 40 can better turn over the materials.

[0057] Multiple groups of clamping plates 43 are fixed on the arc-shaped fixed disk 42, and the arc-shaped fixed disk 42 is arranged on the fixed rod 41. Through this structural arrangement, on the one hand, the clamping plates 43 arranged on the two fixed rods 41 can be effectively separated to prevent the clamping plates 43 from affecting the space between the two fixed rods 41. On the other hand, the clamping plates 43 can be placed at different inclination angles, which is suitable for flipping materials on the belt conveyor roller 30 or the fixed conveyor roller 20, making its application range wider; in addition, an arc-shaped notch is opened in the arc-shaped fixed disk 42, and the clamping plates 43 are located in the arc-shaped notch opened on the arc-shaped fixed disk 42, which can make the placement position of the clamping plates 43 more stable. When clamping the material, the clamping plates 43 will not produce lateral displacement, and the material transfer process is more stable.

[0058] Specifically, during normal operation, the fixed conveyor roller 20 serves as a conveying line connecting multiple processing stations. Multiple belt conveyor rollers 30 are arranged at intervals on the fixed conveyor roller 20, and an overpass turning mechanism 40 and a lower sheet roller 50 are provided at the positions corresponding to the belt conveyor rollers 30. Through this structural setting, there are multiple locations on the entire conveyor line where material turning and conveying operations can be performed. On the one hand, efficiency can be improved and it is suitable for different processing speeds. On the other hand, the material can be turned over without stopping the machine, and the actual application effect is better.

[0059] The overpass flipping method, on the one hand, can reasonably utilize the conveying space without affecting the main line production rhythm, thereby improving the flipping rhythm of conventional flipping machines; on the other hand, it can further improve production and processing efficiency, and the actual application effect is better.

[0060] like Figure 4-5As shown, the T-shaped plate 44 is slidably set on the fixed plate 46, and the fixed plate 46 is fixed on the support frame 10. A hydraulic telescopic rod 47 is provided at the bottom of the fixed plate 46 to drive the T-shaped plate 44 to move in the vertical direction, which can drive the fixed rod 41 and the clamping plate 43 set on the fixed rod 41 to move.

[0061] Specifically, the hydraulic telescopic rod 47 works to drive the T-shaped plate 44 to move, and the overpass flipping mechanism 40 as a whole can be adjusted in the vertical direction, so that it is suitable for material flipping operations on the fixed conveyor roller 20 and the belt conveyor roller 30. A guide groove for guiding the T-shaped plate 44 is provided on the fixed plate 46, so that the overall movement process of the overpass flipping mechanism 40 is smoother, and the overpass flipping mechanism 40 will not shake during the rotation process.

[0062] like Figure 5 As shown, a connecting seat 421 is provided between the clamping plates 43 at the position of the arc-shaped fixing plate 42. The connecting seat 421 is bolted to the arc-shaped fixing plate 42, and the end of the connecting seat 421 extends out of the arc-shaped fixing plate 42. Through the setting of the connecting seat 421, on the one hand, the distance between the clamping plates 43 can be limited to maintain the stability between the clamping plates 43. On the other hand, when the clamping plates 43 clamp the material, the material will not touch the arc-shaped fixing plate 42, thereby avoiding deformation of the arc-shaped fixing plate 42.

[0063] like Figure 6-8 As shown, the fixed conveyor roller 20 includes a rotating roller 21, a first rotating wheel 22, a transmission belt 23, a driving shaft 24, a second rotating wheel 25 and a third motor 26. The rotating roller 21 is rotatably set on the top of the support frame 10. One end of the rotating roller 21 is fixedly connected to the first rotating wheel 22. The first rotating wheel 22 is connected to the second rotating wheel 25 through the transmission belt 23. The second rotating wheels 25 are connected through the driving shaft 24, and the driving shaft 24 is driven by the third motor 26.

[0064] Specifically, the third motor 26 works to drive the driving shaft 24 to rotate, thereby driving the second rotating wheel 25 on the driving shaft 24 to rotate. The second rotating wheel 25 and the first rotating wheel 22 are connected through a transmission belt 23, which can drive the first rotating wheel 22 to rotate, so that the rotating roller 21 rotates accordingly, and the material can be transported. In this way, the driving mode of the rotating roller 21 can be located on the side without affecting the lifting and lowering of the belt conveyor roller 30. At the same time, it is located on the side without equipment on the rotating roller 21, which is convenient for installing the overpass turning mechanism 40, so that its actual application effect is better.

[0065] In addition, multiple second wheels 25 are provided on the driving shaft 24, so that when the third motor 26 controls the rotation of the driving shaft 24, multiple rotating rollers 21 can be driven to rotate simultaneously, thereby avoiding the occurrence of material conveying deviation due to inconsistent rotation speeds of the multiple rotating rollers 21.

[0066] like Figure 9-10 As shown, the belt conveyor roller 30 includes a first conveyor belt 31, a fixed frame 32, a first driven wheel 33, a first driving wheel 34, a first limiting wheel 35, a first motor 36 and a first connecting frame 37. The fixed frame 32 is fixed on the first connecting frame 37. First driven wheels 33 are provided on both sides of the fixed frame 32. The first connecting frame 37 is provided with a first motor 36. The first motor 36 is transmission-connected to the first driving wheel 34. The first conveyor belt 31 is sleeved between the first driving wheel 34 and the first driven wheel 33. First limiting wheels 35 are provided on both sides of the first driving wheel 34 on the first connecting frame 37. The first limiting wheels 35 are fitted to both sides of the first conveyor belt 31.

[0067] The first gear 35 is connected with the first gear 36 and the second gear 37 is connected with the first gear 36 to move along the first gear 36 so that the first gear 36 can move along the first gear 36 to move along the first gear 36.

[0068] When the belt conveyor roller 30 lifts the material above the fixed conveyor roller 20, the space in the fixed frame 32 is located on the top of the fixed conveyor roller 20. When the belt conveyor roller 30 is transferring the material, the fixed conveyor roller 20 can simultaneously convey the material.

[0069] like Figure 10As shown, the support frame 10 is provided with a first lifting mechanism 70 for driving the belt conveyor roller 30 to be adjusted in the vertical direction. The first lifting mechanism 70 includes a first adjusting cylinder 71, a first crank-connecting rod mechanism 72 and a first placing plate 73. The first crank-connecting rod mechanism 72 is provided at the bottom of the first placing plate 73. The first adjusting cylinder 71 is fixed on the support frame 10. The first adjusting cylinder 71 is connected to the first crank-connecting rod mechanism 72 through a transmission. The first adjusting cylinder 71 controls the rotation of the first crank-connecting rod mechanism 72, driving the first placing plate 73 to be adjusted in the vertical direction.

[0070] Specifically, the first lifting mechanism 70 works to drive the first crank-connecting rod mechanism 72 to rotate, thereby adjusting the first placement plate 73 in the vertical direction, thereby adjusting the belt conveyor roller 30 in the vertical direction, which is suitable for different material conveying states.

[0071] like Figure 11-12 As shown, the lower sheet roller 50 includes a second conveyor belt 51, a fixed strip 52, a second driven wheel 53, a second driving wheel 54, a second limiting wheel 55, a second motor 56 and a second connecting frame 57. The fixed strip 52 is fixed on the second connecting frame 57. Second driven wheels 53 are rotatably arranged on both sides of the fixed strip 52. The second connecting frame 57 is provided with a second motor 56. The second driving wheel 54 is transmission-connected to the second motor 56. The second conveyor belt 51 is sleeved between the second driving wheel 54 and the second driven wheel 53. Second limiting wheels 55 are provided on both sides of the second driving wheel 54 on the second connecting frame 57. The second limiting wheels 55 are fitted to both sides of the second conveyor belt 51.

[0072] Specifically, the second motor 56 works to drive the second driving wheel 54 to rotate, so that the second driving wheel 54 and the second conveyor belt 51 on the second driven wheel 53 rotate accordingly, and the material can be conveyed; the second connecting frame 57 is provided with second limiting wheels 55 on both sides of the second driving wheel 54. The second limiting wheels 55 fit the two sides of the second conveyor belt 51, so that the second conveyor belt 51 can maintain tension during the movement, which is more stable for material transportation. By setting the fixed strip 52, the second conveyor belt 51 can be auxiliary limited, so that the second conveyor belt 51 can assist in supporting the material when conveying the material, making the material transportation more stable.

[0073] like Figure 12As shown, the support frame 10 is provided with a second lifting mechanism 80 for driving the lower sheet roller 50 to be adjusted in the vertical direction. The second lifting mechanism 80 includes a second adjusting cylinder 81, a second crank-connecting rod mechanism 82 and a second placing plate 83. A second crank-connecting rod mechanism 82 is provided at the bottom of the second placing plate 83. The second adjusting cylinder 81 is fixed on the support frame 10. The second crank-connecting rod mechanism 82 is transmission-connected to the second adjusting cylinder 81. The second adjusting cylinder 81 controls the rotation of the second crank-connecting rod mechanism 82, driving the second placing plate 83 to be adjusted in the vertical direction.

[0074] Specifically, the second regulating cylinder 81 works to drive the second crank connecting rod mechanism 82 to rotate, thereby adjusting the height of the second placing plate 83, so that the height of the lower sheet roller 50 is adjusted accordingly, which can be applicable to various lower sheet heights.

[0075] The height of the fixed conveying roller 20 is lower than that of the lower sheet roller 50 , and one end of the lower sheet roller 50 extends out of the supporting frame 10 .

[0076] The technical scope of the present invention is not limited to the contents of the above description. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical idea of ​​the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
