Description

Technical Field

[0001] The present invention relates to the technical field of conveying mechanisms, in particular to a conveying mechanism for a flat steel cutting machine. Background Art

[0002] Flat steel cutting machine is a mechanical equipment specially used for cutting flat steel. It is widely used in fields such as construction, mechanical processing, bridge and tunnel engineering. Compared with manual cutting, flat steel cutting machine can greatly improve work efficiency, reduce manual labor intensity, and use mechanical cutting instead of manual operation, which reduces construction risks and improves safety. Flat steel cutting machine needs to transport flat steel through a conveying mechanism when cutting flat steel. During the transportation of flat steel, in order to ensure that it does not deviate when cut, a guide mechanism needs to be set for it to ensure its accurate transportation. The guide mechanism on the conveying mechanism of flat steel cutting machine under the existing technology is set from the starting point of transportation to the end point of transportation to guide it during the entire transportation process. Although this can prevent it from deviating, the setting of the guide mechanism from the starting point to the end point makes the entire device structure more complicated, too cumbersome and the device cost is high. It is not possible to adjust the flat steel at the cutting point to enable it to be accurately cut and realize convenient unloading of flat steel. Summary of the Invention

[0003] The object of the present invention is to provide a conveying mechanism for a flat steel cutting machine to solve the problems raised in the above background technology.

[0004] To achieve the above object, the present invention provides the following technical solutions: A conveying mechanism for a flat steel cutting machine includes a conveyor platform, a conveyor roller is installed on the conveyor platform, and a flat steel driving assembly is provided at the end of the conveyor platform. The flat steel driving assembly drives the conveyor platform to move by the movement of the flat steel. The flat steel drive assembly is connected to a flat steel adjustment mechanism, which is installed on the conveyor platform. The flat steel drive assembly drives the flat steel adjustment mechanism to move and adjust the position of the flat steel. The flat steel driving assembly is also connected to a flat steel receiving assembly, which receives the cut flat steel; The conveyor platform is also provided with a downward buffer mechanism, which buffers the flat steel receiving assembly so that it moves downward smoothly.

[0005] Preferably, the flat steel driving assembly includes a pushed plate frame, a first connecting rod and a second connecting rod. During the conveying process, the flat steel contacts the pushed plate frame and drives the pushed plate frame to move.

[0006] Preferably, there are two first connecting rods, which are hinged on both sides of the pushed plate frame respectively, and the first connecting rods are connected to the flat steel adjustment mechanism.

[0007] Preferably, an extension connecting plate is fixedly provided on the pushed plate frame, the extension connecting plate is hinged to the second matching connecting rod, and the lower end of the second matching connecting rod is connected to the flat steel receiving assembly.

[0008] Preferably, the flat steel adjustment mechanism includes a movable carrier bar and a movable slat, the movable carrier bar is fixedly provided with a supporting carrier rod, the supporting carrier rod is fixedly provided with a guiding carrier bar, and the position of the flat steel is adjusted by the guiding carrier bar.

[0009] Preferably, a movable slat is installed on the movable carrier bar, and a pressure steel plate is fixedly provided on the movable slat, and the pressure steel plate presses on the flat steel when the flat steel is cut.

[0010] Preferably, the flat steel receiving assembly includes a steel receiving box and a sealing strip. The steel receiving box is driven to move by the push plate frame, and a steel discharge channel is opened on the steel receiving box, and the cut flat steel is discharged through the steel discharge channel.

[0011] Preferably, the blocking strip is installed on the steel box, and when the steel box receives the cut flat steel, the blocking strip blocks the steel discharge channel.

[0012] Preferably, the downward buffer mechanism includes a buffer cylinder, a cylinder bottom sealing plate and a gravity bar, and the cylinder bottom sealing plate is movably mounted on the buffer cylinder.

[0013] Preferably, when the steel box moves upward, the lower port of the buffer cylinder is in an open state.

[0014] Preferably, the gravity bar is connected to the cylinder bottom sealing plate to lock the cylinder bottom sealing plate in position.

[0015] Compared with the prior art, the present invention has the following advantages: 1. During the conveying process of flat steel, its conveying front end will contact with the pushed plate frame, so that the pushed plate frame will be driven to move under the action of the flat steel. As the pushed plate frame moves, the pushed plate frame will drive the movable carrier bar to move, and then the movable carrier bar will move toward the direction of the flat steel. Finally, it will contact with the flat steel to adjust the position of the flat steel so that it will not be in an offset state, ensuring smooth cutting. That is, the movement of the flat steel drives the pushed plate frame to move to achieve the adjustment of the position of the flat steel, which is very convenient.

[0016] 2. When the movable carrier moves, it will also drive the movable slats to move downward, and then the pressure steel plate on the movable slats will move downward, and finally the pressure steel plate will be pressed on the flat steel. In this way, under the action of the pressure steel plate, it can prevent the flat steel from warping at one end during the cutting process, making it impossible to cut smoothly and causing safety hazards.

[0017] 3. In addition, when the pushed plate rack moves, it will also drive the steel box to move upward, so that the cut flat steel can automatically fall into the steel box under the action of gravity for collection. The steel box moves upward, so that the flat steel is closer to it and can fall safely into the steel box. After the cut flat steel falls, the pushed plate rack loses its restriction, and the steel box moves down and reset under the action of the gravity of the flat steel and the steel box. The pushed plate rack resets, and the steel box moves downward with the cut flat steel, and can automatically discharge the material under the action of the inner supporting slope. In the process of moving downward, the steel box can be buffered by the air inside the buffer cylinder so that it can reset smoothly to avoid excessive impact. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] like Figure 1 、 Figure 5 and Figure 7 As shown, the flat steel receiving assembly includes a steel box 3 and a blocking strip 4. The pushed plate frame 2 drives the steel box 3 to move, and a steel discharge channel 32 is provided on the steel box 3. The cut flat steel is discharged through the steel discharge channel 32. The blocking strip 4 is installed on the steel box 3. When the steel box 3 receives the cut flat steel, the blocking strip 4 blocks the steel discharge channel 32. The interior of the steel box 3 is fixedly provided with an inner supporting inclined surface 31, and a support block 33 is fixedly provided on one side of the steel discharge channel 32 of the steel box 3. A limited position channel 34 is provided on the support block 33. A bearing outer plate 35 is fixedly provided at one end of the steel box 3. An upper convex connecting frame 36 is fixedly provided on the bearing outer plate 35. The upper convex connecting frame 36 is connected to the second supporting frame The connecting rod 25 is hinged, and a push-up plate 37 is fixedly provided on the bearing outer plate 35.

[0035] like Figure 1 、 Figure 4 、 Figure 7 、 Figure 8 and Figure 9As shown, the downward buffer mechanism includes a buffer cylinder 19, a cylinder bottom sealing plate 7 and a gravity bar 8. The cylinder bottom sealing plate 7 is movably installed on the buffer cylinder 19. When the steel box 3 moves upward, the lower end of the buffer cylinder 19 is in an open state. The gravity bar 8 is connected to the cylinder bottom sealing plate 7 to lock the cylinder bottom sealing plate 7 in position. The buffer cylinder 19 is fixedly arranged at the lower end of the loading support plate 18. An exhaust channel 190 is opened at the upper end of the buffer cylinder 19, and an exhaust hole 191 is opened on the circumference of the lower end of the buffer cylinder 19. In addition, the lower end of the buffer cylinder 19 is provided with an exhaust channel 190. The lower bearing blocks 192 are symmetrically fixed on both sides of the end, and a movable socket 193 is opened on the lower bearing block 192, which cooperates with the cylinder plate 39 to be inserted into the buffer cylinder 19, and its side surface contacts the inner wall of the buffer cylinder 19. The cylinder bottom sealing plate 7 can seal the lower port of the buffer cylinder 19, and the cylinder bottom sealing plate 7 is symmetrically fixed with upper protrusions 71, and the upper protrusions 71 are fixedly provided with a first supporting rod 72, which is inserted into the movable socket 193, and the cylinder bottom sealing plate 7 is also fixed with an upper connecting strip 73, and the upper end of the upper connecting strip 73 is fixedly provided with a supporting rod. The second supporting rod 75 is fixedly provided on the supporting plate 74, and the second supporting rod 75 is inserted into the movable bearing hole 183, and the second supporting rod 75 is sleeved with a connecting spring 751. The two ends of the connecting spring 751 are respectively fixed on the supporting support plate 18 and the supporting plate 74, and the upper end of the supporting plate 74 is fixedly provided with an inclined top frame 76. The surface of the inclined top frame 76 is smooth and has no burrs. When the supporting steel box 3 does not move upward, the push-up plate 37 contacts the lower end of the inclined top frame 76. At this time, the connecting spring 751 is in a stretched state. The bottom sealing plate 7 of the cylinder does not block the lower port of the buffer cylinder 19. The two sides of the load-bearing matching plate 74 are symmetrically fixed with third supporting rods 77. The third supporting rods 77 are inserted in the supporting frame 184, and a locking socket 78 is provided on the third supporting rod 77. The gravity bar 8 is symmetrically fixed with matching support bars 81, and the gravity bar 8 is also symmetrically fixed with locking rods 82. When the bottom sealing plate 7 does not block the lower port of the buffer cylinder 19, the locking rod 82 is inserted in the locking socket 78, and the bottom sealing plate 7 is fixed by the locking rod 82.

[0036] When the conveyor platform 1 is conveying the flat steel, the flat steel will partially protrude from the outside of the conveyor platform 1, and the flat steel will contact the pushed plate frame 2. As the flat steel moves, the flat steel will push the pushed plate frame 2 to move away from the conveyor platform 1. As the pushed plate frame 2 moves, the two movable carriers 5 will be driven to move toward each other under the action of the first connecting rod 24, and then move toward the direction of the flat steel. If the flat steel deviates during the conveying process, the guide carrier 53 will contact the flat steel as the movable carrier 5 moves. Under the action of the guide carrier 53, the flat steel will be pushed to move and adjust its position until the guide carriers 53 on both sides of the flat steel are in contact with the flat steel. In this way, the adjustment of the position of the flat steel can be completed to ensure that it is cut. The accuracy of the adjustment is achieved, and in the process of adjustment, as the guide carrier strip 53 moves, the driving connecting column 62 will move along the upward channel 17, cross the transition channel 16 to the downward channel 15, and then drive the moving slat 6 to move downward. As the moving slat 6 moves downward, the pressing steel plate 63 on the moving slat 6 will be pressed on the flat steel that does not protrude from the conveyor platform 1. At this time, the part of the flat steel protruding from the conveyor platform 1 is the part to be cut off, and the downward pressure of the pressing steel plate 63 prevents the flat steel from tilting at one end during the cutting process, especially when the flat steel is cut for the last time, the safety of the flat steel can be fully guaranteed during the cutting process. In addition, when the pushed plate frame 2 moves away from the conveyor platform 1, it will drive the supporting steel plate 63 under the action of the second connecting rod 25. The box 3 moves upward, so that the steel box 3 is close to the flat steel, so that the cut flat steel can fall safely into the steel box 3, and when the steel box 3 moves upward, the blocking bar 4 will move downward relative to the steel box 3 under the action of gravity, thereby blocking the steel discharge channel 32, and at this time the lower port of the buffer cylinder 19 is in an open state, so that when the matching cylinder plate 39 moves upward, air can quickly enter the buffer cylinder 19 without causing upward obstruction. In the process of the steel box 3 moving upward, the bearing outer plate 35 will eventually contact the matching support bar 81, so that under the action of the bearing outer plate 35, the gravity bar 8 will be pushed upward to move the locking rod 82 upward, so that it can exit the locking socket 78, so that the cylinder bottom sealing plate 7 can be in In the unlocked state, the bottom sealing plate 7 is driven to move under the action of the connecting spring 751, so that it blocks the lower port of the buffer cylinder 19, and then the flat steel can be cut. The cut flat steel falls into the steel box 3 under the action of gravity to be collected. After the flat steel falls into the steel box 3, the pushed plate frame 2 loses its restriction. Under the action of the gravity of the cut flat steel and the steel box 3, the two move downward together. In the downward movement process, the air on the lower side of the matching cylinder plate 39 in the buffer cylinder 19 can only be slowly discharged from the exhaust hole 191. Because the exhaust hole 191 is set to be small, the discharge of air is hindered, which can play a certain buffering role in the downward movement of the steel box 3 under the resistance of air discharge, so that it can fall and reset smoothly.The huge impact between the flat steel and the steel box 3 is avoided, and when the contact matching block 42 contacts the limit contact plate 181, the blocking strip 4 will no longer move. As the steel box 3 moves downward, the steel discharge channel 32 will be opened. At this time, the steel box is also reset. Under the action of the inner supporting inclined surface 31 inside the steel box 3, the flat steel is discharged from the steel discharge channel 32, and it is automatically discharged, which is very convenient. In addition, when the steel box 3 is about to reach the reset position in the process of moving downward, the push-up plate 37 will contact the inclined top frame 76, and the push-up plate 37 will push the inclined top frame 76 moves, thereby causing the bottom sealing plate 7 to move, so that the lower end of the buffer tube 19 is in an open state, which facilitates the next upward movement of the steel box 3. In addition, when the steel box 3 moves downward, the bearing outer plate 35 will separate from the gravity bar 8, and the locking plug 82 will not move downward under the support of the third support rod 77. When the bottom sealing plate 7 reaches the reset position and does not block the lower end of the buffer tube 19, the locking plug 82 is aligned with the locking plug hole 78. In this way, under the action of gravity, the locking plug 82 moves downward and is inserted into the locking plug hole 78, thereby fixing the bottom sealing plate 7.
