The gear frame 50 is alternately supported by the first lower rotating fixed support seat 20 and alternately meshed with the first gear 38 and the second gear 39. The same-direction rotation of the first gear 38 and the second gear 39 drives the first upper rotating gear frame 49 and the first lower rotating gear frame 50 to rotate, thereby driving the entire rotating frame 12 to rotate. The centers of the upper and lower beams of the first rectangular beam 44 and the second rectangular beam 45 are both installed with roller assembly mounting seats 51. The upper and lower beams of the first and second rectangular beams 44 and 45 are both installed with adjusting cylinder mounting seats 52.

[0037] like Figures 7 to 9 As shown, the rolling assembly is formed by an upper roller assembly 55 and a lower roller assembly 56 symmetrically combined in the upper and lower parts. The upper roller assembly 55 and the lower roller assembly 56 are both connected by a middle transmission pulley assembly 57 and roller assemblies on the left and right sides. The transmission pulley assembly 57 is composed of a plurality of transmission synchronous pulleys 62, a transmission synchronous belt used in conjunction with the transmission synchronous pulleys 62, and a mounting plate 61. The mounting plate 61 is connected to the support frame 58, and the support frame 58 is fixed to the roller assembly mounting seat 51. The roller assembly is composed of a plurality of rollers 63, a roller shaft 65 used in conjunction with the rollers 63, and a plurality of connecting plates 64. The sheet passes between the upper roller assembly 55 and the lower roller assembly 56 and is driven to move by the transmission synchronous belt. The synchronous pulley at the end of the upper roller assembly 55 is connected to the first bevel gear 59, and the synchronous pulley at the end of the lower roller assembly 56 is connected to the second bevel gear 60. The first bevel gear 59 and the second bevel gear 60 are symmetrical with respect to the center.

[0038] like Figures 10 and 11As shown, the transmission assembly 14 includes a transmission drive motor mounting plate 66, which is fixed to the first rectangular frame 23. One side of the transmission drive motor mounting plate 66 is obliquely connected to a lifting cylinder 73 and a fixed bearing sleeve 68. The bearing in the fixed bearing sleeve 68 is upwardly connected to the third bevel gear 70, and the third bevel gear 70 is sleeved with a movable bearing seat 69. The movable bearing seat 69 is obliquely downwardly connected to a lever pair 71. The fixed bearing sleeve 68 is vertically mounted with a rotating pin mounting seat 75. The other side of the transmission drive motor mounting plate 66 is vertically mounted with a transmission drive motor 67. The output end of the lifting cylinder 73 is connected to a Y-type cylinder joint 72, and the Y-type cylinder joint 72 is connected to the lever pair 71. The output end of the transmission drive motor 67 passes through the transmission drive motor mounting plate 66 and is connected to the fifth bevel gear 77. The fourth bevel gear 76 is meshed with the fifth bevel gear 77. A rotating pin 74 is provided to pass through the rotating pin mounting seat 75 and the lever pair. When the rotating frame 12 is in the initial state, the second bevel gear 60 is meshed with the third bevel gear 70. At this time, the third bevel gear 70 drives the second bevel gear 60 to rotate, thereby driving the corresponding transmission pulley set 57 to operate. When the rotating frame 12 is flipped 180 degrees, the first bevel gear 59 is meshed with the third bevel gear 70. At this time, the third bevel gear 70 drives the first bevel gear 59 to rotate, thereby driving the corresponding transmission pulley set 57 to operate. When the rotating frame 12 needs to be rotated, the lifting cylinder 73 is extended, and the Y-type cylinder joint 72 lifts one end of the lever pair 71. The movable bearing seat 69 connected to the other end of the lever pair 71 is lowered accordingly, thereby reducing the vertical height of the third gear to prevent the third gear from contacting the first gear 38 or the second gear 39.

[0039] like Figure 12 As shown, an adjusting cylinder 78 is provided, and the output end of the adjusting cylinder 78 is connected to a limit pin 80, and the limit pin 80 is vertically connected to a support frame connecting plate 79, and the support frame connecting plate 79 is connected to the support seat, and the limit pin 80 has a floating groove 81, and the support frame connecting plate 79 is located in the floating groove 81 and floats up and down, and the limit pin 80 is connected to the adjusting cylinder mounting plate 82 through a copper sleeve 83, and a mounting pin 84 is provided to connect the adjusting cylinder mounting plate 82 and the support frame connecting plate 79 respectively, and the mounting pin 84 is sleeved with a spring 85, and the adjusting cylinder mounting plate 8 2 is fixed to the adjusting cylinder mounting base 52, and the adjusting cylinder 78 is lifted upward, driving the limit pin 80 to lift upward to control the distance between the upper roller assembly 55 and the lower roller assembly 56. At the same time, the spring 85 in the mounting pin 84 cooperates with the support frame connecting plate 79 to allow the support frame connecting plate 79 to float up and down in the floating groove 81, thereby clamping sheets of different thicknesses and increasing the friction between the sheet and the contact surfaces of the upper roller assembly 55 and the lower roller assembly 56, thereby ensuring that the sheet can be clamped during transportation and flipping.

[0040] The working process and principle of the present invention are as follows: when the present invention is in the initial state, according to the thickness of the sheet, the distance between the upper roller assembly 55 and the lower roller assembly 56 is adjusted by adjusting the cylinder 78, and the sheet is placed from the workbench of the previous process onto the transmission synchronous belt of the lower roller assembly 56, and the lifting cylinder 73 is controlled to engage the third bevel gear 70 with the second bevel gear 60, and the transmission drive motor 67 is started and the second bevel gear 60 is driven to rotate by the third bevel gear 70. The rotation of the second bevel gear 60 drives the transmission synchronous belt to transport the entire sheet to between the upper roller assembly 55 and the lower roller assembly 56, and the adjusting cylinder 78 is further controlled to make the rollers 63 of the upper roller assembly 55 and the lower roller assembly 56 and the transmission synchronous belt tightly clamp the sheet. At this time, the lifting cylinder 73 is controlled to separate the third bevel gear 70 from the second bevel gear 60, and the rotating frame drive motor 37 is started to drive the rotating synchronous belt through the third synchronous belt pulley 34, so that the first synchronous belt The first gear 38 and the second gear 39 rotate along with the first synchronous pulley 32 and the second synchronous pulley 33, and the first gear 38 and the second gear 39 drive the first upper rotating gear frame 49 to rotate, and the first upper rotating gear drives the entire rotating frame 12 to rotate. When the first gear 38 or the second gear 39 is in the gap between the first upper rotating frame 12 and the first lower rotating frame 12, the other gear continues to provide power. After the rotating frame 12 rotates 180°, the rotating frame drive motor 37 is stopped, and the regulating cylinder 78 is controlled to increase the gap between the upper roller assembly 55 and the lower roller assembly 56. At the same time, the lifting cylinder 73 is controlled to engage the third bevel gear 70 with the first bevel gear 59, and the transmission drive motor 67 is restarted. The rotation of the third bevel gear 70 drives the first bevel gear 59 to rotate, and the rotation of the first bevel gear 59 drives the transmission synchronous belt of the upper roller assembly 55 to operate, further transmitting the sheet to the next process.
