A conveying mechanism for a flat steel cutting machine

Abstract

This invention relates to the field of conveying mechanism technology, specifically to a conveying mechanism for a flat steel cutting machine. The mechanism includes a conveyor platform with conveying rollers mounted on it. A flat steel drive assembly is located at the end of the conveyor platform, moving the flat steel as it moves. The flat steel drive assembly is connected to a flat steel adjustment mechanism mounted on the conveyor platform. During conveying, the front end of the flat steel contacts a pusher frame, causing the pusher frame to move under the action of the flat steel. This movement of the pusher frame then moves a movable carrier bar, which in turn moves towards the flat steel, ultimately contacting and adjusting the flat steel's position to prevent it from shifting and ensure smooth cutting.

Description

Technical Field

[0001] This invention relates to the field of conveying mechanism technology, specifically a conveying mechanism for a flat steel cutting machine. Background Technology

[0002] A flat steel cutting machine is a specialized mechanical device for cutting flat steel. It is widely used in construction, machining, bridge and tunnel engineering, and other fields. Compared to manual cutting, it significantly improves work efficiency, reduces labor intensity, and lowers construction risks and improves safety by replacing manual operation with mechanical cutting. When cutting flat steel, a conveying mechanism is needed to transport the steel. To ensure accurate transport and prevent deviation during transport, a guiding mechanism is required. Current flat steel cutting machines use guiding mechanisms that extend from the starting point to the end of the conveying process. While this prevents deviation, the long-range guiding mechanism makes the entire device complex, cumbersome, and costly. It also fails to allow for precise cutting at the cutting point and convenient unloading of the flat steel. Summary of the Invention

[0003] The purpose of this invention is to provide a conveying mechanism for a flat steel cutting machine to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A conveying mechanism for a flat steel cutting machine includes a conveyor platform, on which a conveyor roller is mounted, and at the end of the conveyor platform is a flat steel driving assembly, which moves by moving the flat steel.

[0006] 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.

[0007] The flat steel drive assembly is also connected to a flat steel receiving assembly, which receives the cut flat steel.

[0008] The conveyor platform is also equipped with a downward buffer mechanism, which buffers the flat steel receiving component to make it move downward smoothly.

[0009] Preferably, the flat steel drive assembly includes a push plate frame, a first connecting rod, and a second connecting rod. During the conveying process, the flat steel comes into contact with the push plate frame, driving the push plate frame to move.

[0010] Preferably, there are two first connecting rods, which are respectively hinged to both sides of the pushed plate frame, and the first connecting rods are connected to the flat steel adjustment mechanism.

[0011] Preferably, an extended connecting plate is fixedly provided on the pushed plate frame, the extended connecting plate is hinged to the second connecting rod, and the lower end of the second connecting rod is connected to the flat steel receiving assembly.

[0012] Preferably, the flat steel adjustment mechanism includes a movable carrier bar and a movable plate bar. A support rod is fixedly installed on the movable carrier bar, and a guide carrier bar is fixedly installed on the support rod. The position of the flat steel is adjusted by the guide carrier bar.

[0013] Preferably, a movable strip is installed on the movable carrier bar, and a pressure plate is fixedly installed on the movable strip. When the flat steel is cut, the pressure plate presses on the flat steel.

[0014] Preferably, the flat steel receiving assembly includes a steel receiving box and a sealing strip. The steel receiving box is moved by the push plate frame, and a steel discharge channel is provided on the steel receiving box for discharging the cut flat steel.

[0015] Preferably, the sealing strip is installed on the steel receiving box, and the sealing strip blocks the steel discharge channel when the steel receiving box receives the cut flat steel.

[0016] Preferably, the downward buffer mechanism includes a buffer cylinder, a bottom sealing plate, and a gravity strip, with the bottom sealing plate movably mounted on the buffer cylinder.

[0017] Preferably, the lower port of the buffer cylinder is in the open state during the upward movement of the steel support box.

[0018] Preferably, the gravity strip is connected to the bottom sealing plate of the cylinder to lock the bottom sealing plate in position.

[0019] Compared with the prior art, the beneficial effects of the present invention are: the present invention has a reasonable structural design and strong functionality, and has the following advantages:

[0020] 1. During the conveying process, the front end of the flat steel will come into contact with the pusher frame. Under the action of the flat steel, the pusher frame will move. As the pusher frame moves, it will drive the movable carrier bar to move, which in turn will move towards the flat steel and finally come into contact with the flat steel to adjust its position so that it is not in a deviated state, ensuring smooth cutting. That is, the position adjustment of the flat steel is achieved by moving the pusher frame through the movement of the flat steel, which is very convenient.

[0021] 2. When the movable carrier bar moves, it will also drive the movable plate downward, which in turn causes the pressure plate on the movable plate to move downward, eventually pressing the pressure plate onto the flat steel. In this way, the pressure plate can prevent one end of the flat steel from curling up during the cutting process, which would prevent the cutting from being carried out smoothly and cause safety hazards.

[0022] 3. In addition, when the pusher frame moves, it also moves the steel support box upwards. This allows the cut flat steel to fall automatically into the steel support box under the action of gravity for collection. As the steel support box moves upwards, the distance between it and the flat steel is reduced, allowing it to fall safely into the steel support box. After the cut flat steel falls, the pusher frame is no longer restricted. Under the action of gravity between the flat steel and the steel support box, the steel support box moves downwards and resets. The pusher frame resets, and the steel support box moves downwards with the cut flat steel. Under the action of the inner inclined surface, the material can be automatically discharged. During the downward movement of the steel support box, the air inside the buffer cylinder can buffer it, allowing it to reset smoothly and avoiding excessive impact. Attached Figure Description

[0034] This invention provides a technical solution:

[0035] like Figure 1 As shown, a conveying mechanism for a flat steel cutting machine includes a conveyor platform 1, on which a conveyor roller 10 is installed.

The flat steel driving assembly is also connected to a flat steel receiving assembly, which receives the cut flat steel. A downward buffer mechanism is also provided on the conveyor platform 1, which buffers the flat steel receiving assembly to make it move downward smoothly.

[0036] like Figure 2 , Figure 3 and Figure 4 As shown, a bearing insertion cavity 11 is provided at the end of the conveyor platform 1, and a matching bearing plate 12 is also fixedly provided at the end of the conveyor platform 1. A support insertion hole 13 is provided on the matching bearing plate 12. A downward groove 14 is provided on the matching bearing plate 12 above the support insertion hole 13. A downward channel 15 is provided on the matching bearing plate 12 next to the downward groove 14. The downward channel 15 is connected to a transition channel 16. The transition channel 16 is connected to an upward channel 17. The internal heights of the downward channel 15, the transition channel 16, and the upward channel 17 are equal. A load-bearing support plate 18 is also fixedly provided on the lower side of the end of the conveyor platform 1. A limit contact plate 181 is fixedly provided on one side of the load-bearing support plate 18. An adapter hole 182 and a movable bearing hole 183 are provided on the load-bearing support plate 18. In addition, a support frame 184 and a hollow bearing cylinder 185 are symmetrically fixedly provided at the end of the load-bearing support plate 18.

[0037] like Figure 1 and Figure 6 As shown, the flat steel drive assembly includes a pushed plate frame 2, a first connecting rod 24, and a second connecting rod 25. During the conveying process, the flat steel contacts the pushed plate frame 2, causing the pushed plate frame 2 to move. There are two first connecting rods 24, which are respectively hinged on both sides of the pushed plate frame 2. The first connecting rods 24 are connected to the flat steel adjustment mechanism. The pushed plate frame 2 is symmetrically fixed with mounting support rods 21, which are inserted into the bearing insertion cavity 11. The two sides of the pushed plate frame 2 are symmetrically fixed with connecting protrusions 22, which are hinged to the first connecting rods 24.

[0038] like Figure 5 As shown, an extension connecting plate 23 is fixedly installed on the pushed plate frame 2. The extension connecting plate 23 is hinged to the second connecting rod 25, and the lower end of the second connecting rod 25 is connected to the flat steel receiving assembly.

[0039] like Figure 1 and Figure 6As shown, the flat steel adjustment mechanism includes a movable carrier bar 5 and a movable plate bar 6. A support rod 52 is fixedly mounted on the movable carrier bar 5, and a guide rail 53 is fixedly mounted on the support rod 52. The position of the flat steel is adjusted by the guide rail bar 53. The other end of the first connecting rod 24 is hinged to the movable carrier bar 5. The support rod 52 is inserted into the support insertion hole 13. The movable carrier bar 5 has a first connecting hole 51, and the guide rail bar 53 has a second connecting hole 54. The movable plate bar 6 is mounted on the movable carrier bar 5, and a pressure plate is fixedly mounted on the movable plate bar 6. 63. When the flat steel is cut, the pressure plate 63 presses on the flat steel. The moving strip 6 is also fixedly provided with a first connecting rod 61, which is inserted into the first connecting hole 51. The moving strip 6 next to the first connecting rod 61 is also fixedly provided with a driving connecting column 62, which is inserted into the upper moving channel 17 and contacts the inner wall of the upper moving channel 17. The pressure plate 63 is fixedly provided with a second connecting rod 64, which is inserted into the second connecting hole 54. In addition, the setting of the lower moving groove 14 facilitates the downward movement of the moving strip 6.

[0040] like Figure 1 , Figure 5 and Figure 7 As shown, the flat steel receiving assembly includes a steel receiving box 3 and a sealing strip 4. The steel receiving box 3 is moved by the push plate frame 2, and a steel discharge channel 32 is provided on the steel receiving box 3 for discharging the cut flat steel. The sealing strip 4 is installed on the steel receiving box 3. When the steel receiving box 3 receives the cut flat steel, the sealing strip 4 blocks the steel discharge channel 32. An inner bearing inclined surface 31 is fixedly provided inside the steel receiving box 3, and a support block 33 is fixedly provided on one side of the steel receiving box 3 where the steel discharge channel 32 is provided. A limit channel 34 is provided on the support block 33. A bearing outer plate 35 is fixedly provided at one end of the steel receiving box 3, and an upper protruding connecting frame 36 is fixedly provided on the bearing outer plate 35. The upper protruding connecting frame 36 and the second matching... The connecting rod 25 is hinged, and a push plate strip 37 is fixedly installed on the bearing outer plate 35. In addition, a hanging bearing rod 38 is fixedly installed at the lower end of the bearing outer plate 35. The hanging bearing rod 38 is inserted into the adapter hole 182, and a mating cylinder plate 39 is fixedly installed at the lower end of the hanging bearing rod 38. Limiting connecting rods 41 are fixedly installed at both ends of the sealing strip 4. The limiting connecting rods 41 are inserted into the limiting channel 34, and a contact mating block 42 is fixedly installed at the lower end of the limiting connecting rod 41. When the steel bearing box 3 does not move upward, its lower end face is in contact with the upper end face of the load support plate 18, and the contact mating block 42 is in contact with the limiting contact plate 181 at this time. At this time, the sealing strip 4 does not block the steel discharge channel 32.

[0041] like Figure 1 , Figure 4 , Figure 7 , Figure 8 and Figure 9As shown, the downward buffer mechanism includes a buffer cylinder 19, a bottom sealing plate 7, and a gravity bar 8. The bottom sealing plate 7 is movably mounted on the buffer cylinder 19. During the upward movement of the steel support box 3, the lower end of the buffer cylinder 19 is in an open state. The gravity bar 8 is connected to the bottom sealing plate 7 to lock the position of the bottom sealing plate 7. The buffer cylinder 19 is fixedly installed at the lower end of the load-bearing support plate 18. An exhaust channel 190 is provided at the upper end of the buffer cylinder 19, and an exhaust hole 191 is provided on the circumference of the lower end of the buffer cylinder 19. In addition, the lower end of the buffer cylinder 19... Lower bearing blocks 192 are symmetrically fixed on both sides of the buffer cylinder 19. Each lower bearing block 192 has a movable insertion hole 193, which is inserted into the buffer cylinder 19 along with the cylinder plate 39. The lower bearing block 192's side surface contacts the inner wall of the buffer cylinder 19. A bottom sealing plate 7 can seal the lower end of the buffer cylinder 19. An upper protrusion 71 is symmetrically fixed on the bottom sealing plate 7, and a first bearing rod 72 is fixed on the upper protrusion 71. The first bearing rod 72 is inserted into the movable insertion hole 193. An upper connecting strip 73 is also fixedly fixed on the bottom sealing plate 7, and a bearing rod is fixedly installed at the upper end of the upper connecting strip 73. A second support rod 75 is fixedly installed on the load-bearing plate 74. The second support rod 75 is inserted into the movable load-bearing hole 183, and a connecting spring 751 is sleeved on the second support rod 75. The two ends of the connecting spring 751 are fixed to the load-bearing support plate 18 and the load-bearing plate 74, respectively. An inclined top bracket 76 is fixedly installed at the upper end of the load-bearing plate 74. The surface of the inclined top bracket 76 is smooth and burr-free. When the steel box 3 is not moving upward, the push plate strip 37 is in contact with the lowermost end of the inclined top bracket 76. At this time, the connecting spring 751 is in a stretched state. The bottom sealing plate 7 does not block the lower port of the buffer cylinder 19. The two sides of the bearing plate 74 are symmetrically fixed with third support rods 77. The third support rods 77 are inserted into the support frame 184, and the third support rods 77 are provided with locking holes 78. The gravity strip 8 is symmetrically fixed with matching support strips 81, and the gravity strip 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 rods 82 are inserted into the locking holes 78, and the bottom sealing plate 7 is fixed by the locking rods 82.

[0042] During the conveyor transport of the flat steel, part of the flat steel protrudes from the outside of the conveyor platform 1 and contacts the pushed frame 2. As the flat steel moves, it pushes the pushed frame 2 away from the conveyor platform 1. This movement of the pushed frame 2, under the action of the first connecting rod 24, causes the two movable carrier bars 5 to move towards each other, and further towards the flat steel. If the flat steel deviates during transport, the guide carrier bars 53 will contact the flat steel as the movable carrier bars 5 move. Under the action of the guide carrier bars 53, the flat steel will be moved to adjust its position until both guide carrier bars 53 on both sides are in contact with the flat steel. This completes the position adjustment of the flat steel, ensuring its cutting. The accuracy of the adjustment is ensured, and during the adjustment process, as the guide bar 53 moves, the drive connecting column 62 will move along the upward channel 17, cross the transition channel 16, and reach the downward channel 15, thereby driving the moving plate 6 to move downward. As the moving plate 6 moves downward, the pressure plate 63 on the moving plate 6 will press on the flat steel that does not protrude from the conveyor table 1. At this time, the part of the flat steel that protrudes from the conveyor table 1 is the part that is about to be cut. The downward pressure of the pressure plate 63 ensures that the flat steel will not have one end tilted up during the cutting process. In particular, it can fully ensure the safety of the flat steel during the final cutting process. In addition, when the pushed plate frame 2 moves away from the conveyor table 1, it will drive the bearing steel under the action of the second connecting rod 25. As the steel box 3 moves upward, it approaches the flat steel, allowing the cut flat steel to fall safely into the steel box 3. Simultaneously, the sealing strip 4 moves downward relative to the steel box 3 under gravity, blocking the steel discharge channel 32. At this time, the lower end of the buffer cylinder 19 is open, allowing air to quickly enter the buffer cylinder 19 as the cylinder plate 39 moves upward without obstructing its upward movement. During the upward movement of the steel box 3, the outer bearing plate 35 eventually contacts the supporting strip 81. Under the action of the outer bearing plate 35, the gravity strip 8 moves upward, causing the locking rod 82 to move upward and disengage from the locking hole 78. This ensures that the bottom sealing plate 7 is in position... In the unlocked state, the bottom sealing plate 7 moves under the action of the connecting spring 751, sealing the lower end of the buffer cylinder 19. Then, the flat steel can be cut. The cut flat steel falls into the steel-bearing box 3 under gravity for collection. After the flat steel falls into the steel-bearing box 3, the pushed plate frame 2 is no longer restricted. Under the weight of the cut flat steel and the steel-bearing box 3, both move downwards. During this downward movement, the air in the buffer cylinder 19 located below the mating cylinder plate 39 can only slowly escape through the exhaust port 191. Because the exhaust port 191 is relatively small, the air escape is obstructed. This resistance to air escape provides a certain buffering effect on the downward movement of the steel-bearing box 3, allowing it to fall and reset smoothly.This avoids a huge impact between the flat steel and the steel-bearing box 3. When the contact block 42 contacts the limiting contact plate 181, the sealing strip 4 will no longer move. As the steel-bearing box 3 moves downward, the steel discharge channel 32 will open, and the steel-bearing box will also reset. Under the action of the inner bearing inclined surface 31 inside the steel-bearing box 3, the flat steel will be discharged from the steel discharge channel 32, achieving automatic discharge, which is very convenient. In addition, when the steel-bearing box 3 is about to reach the reset position during its downward movement, the push plate 37 will contact the inclined top frame 76, and under the action of the push plate 37, the inclined top frame will be pushed. The cylinder bottom sealing plate 7 moves, causing the bottom port of the buffer cylinder 19 to open, facilitating the next upward movement of the steel support box 3. Additionally, when the steel support box 3 moves downward, the outer supporting plate 35 separates from the gravity bar 8, while the locking rod 82, supported by the third support rod 77, will not move downward. When the cylinder bottom sealing plate 7 reaches its reset position, without sealing the bottom port of the buffer cylinder 19, the locking rod 82 aligns with the locking hole 78. Under gravity, the locking rod 82 moves downward and inserts into the locking hole 78, thus fixing the cylinder bottom sealing plate 7.
