[0015] The beneficial effects of the present invention are:

[0016] 1. The shearing piece in the present invention can realize the effect of automatic feeding of single board. The present invention drives the driving rod to rotate through the feeding motor, and the driving rod can drive the fan-shaped wheel to rotate. The driving rod is axially connected to the axis of the fan-shaped wheel. When the fan-shaped wheel rotates, the fan-shaped wheel can push the push rod to rotate through the rotating wheel, so that the push plate above the push rod moves to the end of the plate, and the protruding part of the push plate is just the height of a plate. Then, when the fan-shaped wheel continues to rotate, the distance between the fan-shaped wheel and the guide rod is reduced, and the spring The push rod will be pulled to rotate around the guide rod, and the push plate on the push rod will push a plate forward, so that the end of the plate away from the push plate moves to between the upper feed roller and the lower feed roller. The upper feed roller and the lower feed roller clamp the plate and transmit it to one side of the conveyor. At this time, when the fan-shaped wheel continues to rotate, it will push the push rod to drive the push plate to move, so that the push plate moves to the end of the plate. At this time, the plate will drop onto the push plate, so that reciprocating feeding of a single plate can be realized, which greatly saves feeding time.

[0017] 2. The shearing piece in the present invention can achieve the two effects of shearing and fixing. The pressing motor drives the rotating rod to rotate, and the rotating rod drives the eccentric wheel to rotate. The eccentric wheel drives the pressing plate under the pressing rod to move up and down to achieve the effect of the pressing plate, so that the plate can be fixed and sheared more accurately.

[0018] 3. The present invention is provided with a centering piece, which can center the plate to avoid the problem of large shearing errors caused by the tilt of the plate. Therefore, the centering piece is used to center the ends and sides of the plate, so that the plate can move to a suitable position for pressing and shearing. The centering drive member will drive the two side centering plates to clamp and center the two sides of the plate to avoid the plate from tilting during the transmission process. The end centering plate limits the end of the plate to control the punching width. When the centering and shearing is completed, the supporting cylinder will drive the centering piece to move downward a proper distance, so that the end centering plate can drop to the bottom of the frame, and the sheared plate can be discharged smoothly. This method can achieve accurate punching of the plate.

[0019] 4. The centering drive member in the present invention can realize the separate meshing and centering of the side centering plate and the end centering plate. Since the position of the plate is not fixed during the transmission process, and the different positions of the plate require the side centering plate and the end centering plate to move different distances. Therefore, the centering drive member in the present invention can realize the continued centering of the end centering plate under the premise that the side centering plate has been centered, or the side centering plate can continue to move to realize the left and right centering of the plate when the end centering plate has been centered, wherein the rotating ring is fixedly connected to the driving frame, and the rotating ring is rotatably connected to the centering frame, the centering motor drives the lower worm to rotate, the lower worm drives the upper worm to rotate through the synchronous gear, the upper worm drives the side drive gear to rotate through the upper control gear, and the lower worm drives the end drive gear to rotate through the lower control gear, and the side drive gear and the end drive gear can respectively drive the side centering plate and The end centering plate is moved and aligned. Since the upper control gear and the lower control gear are separately arranged, the rotation of the side drive gear and the end drive gear is not affected during rotation. Therefore, after the side drive gear and the end drive gear rotate at the same time, it is assumed that the side centering plate has been aligned. At this time, due to the limiting effect of the side centering plate, the side drive gear will not rotate, and the upper control gear will continue to rotate. At this time, the upper control gear will revolve relative to the side drive gear, and will drive the entire drive frame to revolve around the side drive gear. At this time, the end centering plate has not moved to the appropriate position. Therefore, when the lower worm gear rotates, it will further drive the lower control gear to rotate around the limit rod, and further drive the end drive gear to rotate on itself to achieve the centering movement of the end centering plate. This method can realize the separate control of the side centering plate and the end centering plate, and avoid the inability to accurately and uniformly align plates with different movement angles.

[0020] 5. When the side driving gear rotates, since the side guide rod on the side centering plate is movably inserted in the side strip hole, and the side strip hole gradually extends toward the outer ring of the side driving gear, and the lower part of the side centering plate is slidably connected to the upper rectangular groove on the limiting plate, and the upper rectangular groove is radially arranged, the side strip hole will drive the side guide rod to move toward the outer ring. Due to the limitation of the upper rectangular groove below, the entire side centering plate will move radially outward, and due to the limiting effect of the rectangular groove, the side plate above the side centering plate can be prevented from rotating, so that the two side plates can always maintain a horizontal and parallel state without tilting, thereby ensuring the centering accuracy during the centering process of the plate. The two side plates are provided with chamfers on one side close to the feeding member. The setting of the chamfer can prevent the plate from being blocked by the side of the side plate and unable to be transmitted. BRIEF DESCRIPTION OF THE DRAWINGS

When the fan-shaped wheel 133 rotates, the fan-shaped wheel 133 can push the pushing rod 136 to rotate through the rotating wheel 1361, so that the pushing plate 135 above the pushing rod 136 moves to the end of the plate, and the protruding part of the pushing plate 135 is just the height of a plate. Then, when the fan-shaped wheel 133 continues to rotate, the distance between the fan-shaped wheel 133 and the guide rod 134 is reduced, and the spring The spring 137 will pull the push rod 136 to rotate around the guide rod 134, and the push plate 135 on the push rod 136 will push a plate forward, so that the end of the plate away from the push plate 135 moves to between the upper feed roller 111 and the lower feed roller 112.

The two synchronous gears 376 are meshed with each other, and the rotating ring 372 is coaxially rotatably connected to the side drive gear 34 and the end drive gear 35. An upper limit rod 3711 and a lower limit rod are longitudinally arranged on the drive frame 371, the upper control gear 377 is rotatably connected to the upper limit rod 3711, and the lower control gear 378 is rotatably connected to the lower limit rod.

The side driving gear 34 is provided with two parallel side strip holes 341, and the side centering plate 32 is slidably inserted in the side strip holes 341. The end driving gear 35 is provided with an end strip hole 351, and the end strip hole 351 is perpendicular to the side strip hole 341 in the axial direction, and the end centering plate 33 is slidably inserted in the end strip hole 351.

Since the position of the plate is not fixed during the conveying process, and the different positions of the plate require the side centering plate 32 and the end centering plate 33 to move different distances, the centering drive member 37 in the present invention can realize the continued centering of the end centering plate 33 under the premise that the side centering plate 32 has been centered, or the side centering plate 32 can continue to move to realize the plate The left and right centering of the components, wherein the rotating ring 372 is fixedly connected to the driving frame 371, the rotating ring 372 is rotatably connected to the centering frame 31, the centering motor 373 drives the lower worm 375 to rotate, the lower worm 375 drives the upper worm 374 to rotate through the synchronous gear 376, the upper worm 374 drives the side drive gear 34 to rotate through the upper control gear 377, the lower worm 375 drives the end drive gear 35 to rotate through the lower control gear 378, and the side drive gear 34 and the end drive gear 35 can respectively drive when they rotate. The side centering plate 32 and the end centering plate 33 are centered by movement. Since the upper control gear 377 and the lower control gear 378 are separately arranged, the rotation of the side drive gear 34 and the end drive gear 35 is not affected during the rotation. Therefore, after the side drive gear 34 and the end drive gear 35 rotate at the same time, it is assumed that the side centering plate 32 has been centered. At this time, due to the limiting effect of the side centering plate 32, the side drive gear 34 will not rotate, and the upper control gear 377 will continue to rotate. At this time, the upper control gear 377 will continue to rotate. 77 will revolve relative to the side drive gear 34, and will drive the entire drive frame 371 to revolve around the side drive gear 34. At this time, the end centering plate 33 has not moved to the appropriate position. Therefore, when the lower worm gear 375 rotates, it will further drive the lower control gear 378 to rotate around the limit rod, and further drive the end drive gear 35 to rotate to achieve the centering movement of the end centering plate 33. This method can realize the separate control of the side centering plate 32 and the end centering plate 33, avoiding the inability to accurately and uniformly align the plates with different movement angles.

When the side driving gear 34 rotates, since the side guide rod 322 on the side centering plate 32 is movably inserted in the side strip hole 341, and the side strip hole 341 gradually extends toward the outer ring of the side driving gear 34, and the lower part of the side centering plate 32 is slidably connected to the upper rectangular groove 3611 on the limiting plate 36, and the upper rectangular groove 3611 is radially arranged, the side strip hole 341 will drive the side guide rod 322 to move toward the outer ring, and due to the restriction of the upper rectangular groove 3611 below, The entire side centering plate 32 moves radially outward in a straight line, and due to the limiting effect of the rectangular groove, the side panel 324 above the side centering plate 32 can be prevented from rotating, so that the two relatively side panels 324 can always maintain a horizontal and parallel state without tilting, thereby ensuring the centering accuracy during the plate centering process. The two side panels 324 are provided with a chamfer 3241 on one side close to the feeding piece 1, and the setting of the chamfer 3241 can prevent the plate from being blocked by the side of the side panel 324 and being unable to be transported.

[0042] The working principle of a centering feeding system of a shearing machine is as follows: first, the feeding motor 131 drives the driving rod 132 to rotate, and the driving rod 132 can drive the fan-shaped wheel 133 to rotate. The driving rod 132 is axially connected to the axis of the fan-shaped wheel 133. When the fan-shaped wheel 133 rotates, the fan-shaped wheel 133 can push the push rod 136 to rotate through the rotating wheel 1361, so that the push plate 135 above the push rod 136 moves to the end of the plate, and the protruding part of the push plate 135 is just the height of a plate. The spring 137 pulls the push rod 136 to rotate around the guide rod 134, and the push plate 135 on the push rod 136 pushes a plate forward to move the plate away from the push plate 135. The end of the plate moves between the upper feed roller 111 and the lower feed roller 112, and the upper feed roller 111 and the lower feed roller 112 clamp the plate and transmit it to one side of the conveying member 2. At this time, when the sector wheel 133 continues to rotate, the spring 137 pulls the push rod 136 to rotate around the guide rod 134, and the push plate 135 on the push rod 136 pushes a plate forward to move the plate away from the push plate 135. The end of the plate moves to between the upper feed roller 111 and the lower feed roller 112. The upper feed roller 111 and the lower feed roller 112 clamp the plate and transmit it to one side of the conveying member 2. The push rod 136 will push the push plate 135 to move, so that the push plate 135 moves to the end of the plate. At this time, the plate will drop onto the push plate 135. In this way, the reciprocating feeding of a single plate can be realized; when the plate moves to the conveying member 2, the active roller 22 will convey the plate to the top of the centering member 3. The centering member 3 can center the plate to avoid the problem of large shearing errors caused by the tilt of the plate. Therefore, the centering member 3 is used to center the ends and sides of the plate so that the plate can It can move to a suitable position and then perform pressing plate 43 and shearing, wherein the centering drive 37 will drive the two side centering plates 32 to clamp and center the two sides of the plate to prevent the plate from tilting during transportation, and the end centering plate 33 will limit the end of the plate to control the punching width. When the centering shearing is completed, the supporting cylinder 51 will drive the centering part 3 to move downward a proper distance, so that the end centering plate 33 can drop to the bottom of the frame, and the sheared plate can be discharged smoothly. This method can achieve accurate punching of the plate.
