Description

Technical Field

[0001] The utility model relates to the technical field of waste steel barrel resource treatment, in particular to a steel barrel cutting, dissecting and flattening device. Background Art

[0002] In order to save resources, the old steel barrels used in the chemical industry are generally reused after being refurbished. However, for some old steel barrels that cannot meet the use standards after being refurbished multiple times, they need to be disassembled to make steel plates for recycling. There are chemical raw materials remaining in the steel barrels. When using the dry process for environmental protection treatment, first, the end cover at one end of the steel barrel needs to be cut off and then burned and heat-cleaned. After cleaning, the end cover and the side wall at the other end of the steel barrel are cut, and finally, it is flattened. In the existing operation process, the cutting of the end cover and side wall of the steel barrel and the flattening of the barrel body after burning and heat-cleaning are mostly assisted by manual labor. The steel barrel needs to be frequently carried, the labor intensity of the operators is high, and the cutting efficiency is low. Content of the Utility Model

[0003] Aiming at the above problems, the purpose of the utility model is to provide a steel barrel cutting, dissecting and flattening device, which integrates functions such as automatic feeding of steel barrels, cutting of the end cover and side wall of steel barrels, and flattening of the barrel body, can reduce the labor intensity of operators, and improve the processing efficiency of cutting and flattening of steel barrels.

[0004] The purpose of the utility model is realized by the following technical solutions:

[0005] Provide a steel barrel cutting, dissecting and flattening device, including a feeding mechanism, a cutting and dissecting device, and a flattening mechanism arranged in sequence along the steel barrel conveying direction. The feeding mechanism includes a storage platform, a first blocking unit arranged on the storage platform, and a second blocking unit arranged on the storage platform near the cutting and dissecting device. The first blocking unit is arranged on one side of the storage platform along the steel barrel conveying direction, and the storage platform is provided with an inclined slope for placing and conveying the steel barrel to be processed.

[0006] The steel barrel cutting and flattening device designed in this solution integrates functions such as automatic feeding of steel barrels, cutting of steel barrel end caps and side walls, and flattening of the barrel body. The feeding mechanism can automatically transfer the steel barrel to the cutting device by using the gravity of the steel barrel for cutting the end cap and side wall of the steel barrel. After cutting, the barrel body is conveyed along the cut seam on the side wall to the flattening mechanism, and the barrel body is initially flattened into a steel plate. The operator places the steel barrel to be processed on the storage platform. The storage platform has an inclined slope, and the steel barrel automatically rolls down to the feeding port of the cutting device and is blocked by the second blocking unit. Subsequently placed steel barrels automatically roll down and stack on the storage platform in sequence. The second steel barrel near the feeding port of the cutting device on the storage platform is blocked by the first blocking unit; when the cutting device finishes processing, the first blocking unit continues to block the second steel barrel near the feeding port of the cutting device on the storage platform to prevent it from rolling and sliding down, and the second blocking unit releases the first steel barrel near the feeding port of the cutting device on the storage platform; when the first steel barrel enters the cutting device, the first blocking unit releases the blocked second steel barrel, and the steel barrels stacked behind it roll down in sequence, and the first blocking unit automatically blocks the steel barrel to prevent it from entering the cutting device. Through the above design solution, automatic feeding of steel barrels is realized, and cutting and flattening processing are completed, eliminating auxiliary operations such as manual cutting and flattening, reducing the workload of manual handling during the processing, not only reducing the labor intensity of the operators, but also improving the processing efficiency.

[0007] Further, the storage platform is provided with guide strips on both sides of the inclined slope, and the guide strips extend along the inclined slope to both ends of the storage platform.

[0008] In order to ensure the orderly rolling of the steel barrels placed on the storage platform and ensure that the steel barrels can enter the cutting device in the established position and direction, guide strips for restricting the positions of both ends of the steel barrels are provided on both sides of the inclined slope and extend throughout the inclined slope. The guide strips do not interfere with the first blocking unit on the side of the storage platform.

[0009] Further, two groups of the first blocking units are provided, and the two groups of the first blocking units are symmetrically arranged on the opposite sides of the storage platform along the steel barrel conveying direction.

[0010] Two groups of the first blocking units are provided. By synchronously blocking with the two groups of the first blocking units, the impact resistance of the first blocking unit to the rolling of the steel barrel is improved, thereby improving the stability and service life of the first blocking unit; at the same time, the occurrence of the situation where the steel barrel may be skewed due to the force on one side is avoided.

[0011] Further, the first blocking unit is provided with a first blocking block and a first driving member for driving the first blocking block to move towards the storage platform. The two ends of the first blocking block are provided with stop portions protruding towards the storage platform.

[0012] Steel drums are stacked in sequence on the storage platform. There is a gap between two adjacent steel drums. When the first driving member drives the first blocking block to move towards the storage platform and the stopping portion extends into the gap between the upper and lower parts of the two adjacent steel drums, the steel drums can be blocked from rolling down. When the first driving member drives the blocking block to retract and the stopping portion withdraws from the gap between the upper and lower parts of the two adjacent steel drums, the steel drums can roll down along the inclined slope of the storage platform.

[0013] Further, the second blocking unit is provided with a second blocking block and a second driving member for driving the second blocking block to move up and down. A rectangular hole is provided on the inclined slope. The second blocking block faces the rectangular hole and can extend or retract into the rectangular hole.

[0014] The steel drum to be processed near the feeding port of the cutting device on the storage platform is blocked by the second blocking unit. A second driving member is arranged below the storage platform. The output end of the second driving member is connected to the second blocking block. A rectangular hole is provided on the inclined slope and the second blocking block is arranged in the rectangular hole. When the second driving member drives the second blocking block to rise out of the inclined slope, the second blocking block plays a blocking role. When the second driving member drives the second blocking block to retract into the rectangular hole, the second blocking block releases the steel drum.

[0015] Further, the cutting device includes a frame. A clamping mechanism for clamping and positioning the steel drum, a end cover cutting mechanism for cutting the end cover of the steel drum above the clamping mechanism, and a transverse cutting mechanism for cutting the side wall of the steel drum are provided on the frame.

[0016] After the steel drum enters the cutting device, the clamping mechanism clamps and positions the steel drum and raises it to the cutting and processing position. The transverse cutting mechanism first performs the task of cutting the side wall of the steel drum, and then the end cover cutting mechanism performs the task of cutting the end cover.

[0017] Further, the clamping mechanism includes two relatively arranged chucks, a third driving member for driving the two chucks to approach or move away from each other, and a fourth driving member for driving the two chucks to lift synchronously. The end cover cutting mechanism is provided with a cutting disc and a fifth driving member for driving the cutting disc to rotate. The cutting disc can be connected to the chuck and drive the chuck to rotate synchronously.

[0018] The third driving member drives two chucks to clamp the steel drum from both ends of the steel drum. The end cover of the steel drum has a groove. The chuck includes a positioning disk and a first toothed disk fixedly connected to the positioning disk. During the clamping process, the positioning disk on one side extends into the groove and abuts against the groove, and the positioning disk on the other side extends into the interior of the barrel body and abuts against the inner surface of the barrel body. The end portions of both ends of the steel drum respectively abut against the first toothed disk. After the steel drum is clamped, the fourth driving member drives the chuck and the steel drum to rise to the cutting position; the cutting disk includes a cutter disk and a second toothed disk fixedly connected to the cutter disk. After the chuck rises, the first toothed disk and the second toothed disk are meshed and connected, and the cutter disk and the positioning disk form a shearing structure. The fifth driving member drives the second toothed disk to rotate and drives the chuck and the steel drum to rotate through the first toothed disk. During the rotation process, the cutter disk and the positioning disk form a shearing structure to cut off the end cover of the steel drum.

[0019] Further, the transverse cutting mechanism includes a cutter, a sixth driving member, a mounting plate, and a seventh driving member. The sixth driving member is arranged on the mounting plate. The cutter is connected to the output end of the sixth driving member. The sixth driving member can drive the cutter to perform a reciprocating linear motion. The mounting plate is connected to the output end of the seventh driving member. The seventh driving member can drive the mounting plate to move up and down.

[0020] Before shearing the end cover of the steel drum, first use the transverse cutting mechanism to cut the side wall of the steel drum. Before the steel drum enters the clamping mechanism, the cutter is at the top of the machine frame to avoid affecting the rolling of the steel drum into the cutting mechanism; when the steel drum is clamped and rises, the seventh driving member drives the mounting plate to move downwards to make the cutter close to the steel drum. When the cutter moves down to the position, the sixth driving member drives the cutter to move along the side wall of the steel drum to cut open the side wall of the steel drum; after the cutting is completed, the seventh driving member drives the mounting plate to move upwards to make the cutter return to the original position.

[0021] Further, a lifting mechanism is further arranged between the two chucks. The lifting mechanism includes a top lifting plate rotatably mounted on the machine frame and an eighth driving member located below the top lifting plate and connected to the top lifting plate. The eighth driving member can drive the top lifting plate to rotate so that the side of the top lifting plate close to the steel drum extends into the cutting seam of the side wall of the steel drum.

[0022] After the transverse cutting mechanism cuts the side wall of the steel drum, the second toothed disk rotates and drives the chuck and the steel drum to rotate. The end cover cutting mechanism starts to cut the end cover of the steel drum from the cutting seam of the side wall. Since the end cover is gradually cut, the side wall of the steel drum and the end cover are gradually separated, and the separated steel plate at the cutting seam warps. The eighth driving member drives the top lifting plate to rotate, and the side of it close to the steel drum extends into the cutting seam of the side wall of the steel drum to lift the warped steel plate. During the rotation of the steel drum, the cut side wall steel plate slides into the flattening mechanism along the top lifting plate. As the steel drum rotates, the end cover of the steel drum is completely cut off, and the side wall steel plate is also completely fed into the flattening mechanism for flattening.

[0023] Furthermore, the flattening mechanism comprises two flattening rollers which are arranged in parallel and rotatably, and there is a gap between the two flattening rollers for the cut steel plate of the side wall of the steel drum to pass through.

[0024] The cut end of the steel plate on the side wall of the steel drum is sent between two flattening rollers along the top rocker plate. After initial flattening by the flattening rollers, the original cylindrical shape is changed and initially transformed into a straight steel plate before the next step of processing is carried out.

[0025] Compared with the prior art, the beneficial effects of the utility model are:

[0026] The steel drum cutting and flattening device designed in this scheme integrates functions such as automatic steel drum feeding, steel drum end cover and side wall cutting, and barrel body flattening. The feeding mechanism can use the gravity of the steel drum to automatically transfer the steel drum to the cutting and flattening device for cutting the steel drum end cover and side wall. After the cutting is completed, the barrel body is transported to the flattening mechanism along the cut seam of the side wall, and the barrel body is initially flattened and pressed into a steel plate. The operator places the steel barrel to be processed on the storage platform, which has an inclined slope. The steel barrel automatically rolls down to the inlet of the cutting and profiling device and is blocked by the second blocking unit. The steel barrels placed subsequently automatically roll down and are stacked on the storage platform in turn. The second steel barrel on the storage platform close to the inlet of the cutting and profiling device is blocked by the first blocking unit; when the cutting and profiling device is processed, the first blocking unit continues to block the second steel barrel on the storage platform close to the inlet of the cutting and profiling device to prevent it from rolling down, and the second blocking unit releases the first steel barrel on the storage platform close to the inlet of the cutting and profiling device; when the first steel barrel enters the cutting and profiling device, the first blocking unit releases the blocked second steel barrel, and the steel barrels stacked behind it roll down in turn, and the first blocking unit automatically blocks the steel barrel from entering the cutting and profiling device. Through the above design scheme, the steel barrels are automatically loaded and the cutting and profiling and flattening processing is completed, the auxiliary operations such as manual cutting and flattening are eliminated, and the workload of manual handling during the processing is reduced, which not only reduces the labor intensity of the operators, but also improves the processing efficiency.

[0032] To facilitate the understanding of the present utility model, the present utility model will be described more comprehensively below with reference to the relevant drawings. The preferred embodiments of the present utility model are shown in the drawings. However, the present utility model can be implemented in many different forms and is not limited to the embodiments described herein.

[0033] As Figures 1 to 4 shown, a steel drum cutting, flattening and warping device is designed, which includes a loading mechanism 1, a cutting device 2, and a flattening mechanism 3 arranged in sequence along the steel drum conveying direction. The loading mechanism 1 includes a storage platform 11, a first blocking unit 12 arranged on the storage platform 11, and a second blocking unit 13 arranged on the storage platform 11 near the cutting device 2. The first blocking unit 12 is arranged on one side of the storage platform 11 along the steel drum conveying direction. The storage platform 11 is provided with an inclined slope for placing and conveying the steel drum to be processed. The slope of the inclined slope 14 is designed to be 5 - 7 degrees, and the discharge port of the storage platform 11 corresponds to the inlet of the cutting device 2.

[0034] The steel barrel cutting and flattening device designed in this solution integrates functions such as automatic feeding of steel barrels, cutting of steel barrel end caps and side walls, and flattening of the barrel body. The feeding mechanism 1 can automatically transfer the steel barrel to the cutting device 2 by using the gravity of the steel barrel for cutting the end cap and side wall of the steel barrel. After cutting, the barrel body is conveyed along the cut seam on the side wall to the flattening mechanism 3 to preliminarily flatten the barrel body into a steel plate. The operator places the steel barrel to be processed on the storage platform 11. The storage platform 11 has an inclined slope 14. The steel barrel automatically rolls down to the feeding port of the cutting device 2 and is blocked by the second blocking unit 13. The subsequently placed steel barrels automatically roll down and stack on the storage platform 11 in sequence. The second steel barrel close to the feeding port of the cutting device 2 on the storage platform 11 is blocked by the first blocking unit 12. When the cutting device 2 finishes processing, the first blocking unit 12 continues to block the second steel barrel close to the feeding port of the cutting device 2 on the storage platform to prevent it from rolling down. The second blocking unit 13 releases the first steel barrel close to the feeding port of the cutting device 2 on the storage platform. When the first steel barrel enters the cutting device 2, the first blocking unit 12 releases the blocked second steel barrel, and the steel barrels stacked behind it roll down in sequence. The first blocking unit 12 automatically blocks the steel barrel to prevent it from entering the cutting device 2. Through the above design solution, automatic feeding of the steel barrel is achieved, and cutting and flattening processing are completed. Manual cutting, flattening and other auxiliary operations are cancelled, and the workload of manual handling in the processing process is reduced. This not only reduces the labor intensity of the operators, but also improves the processing efficiency.

[0035] As Figure 1 shown, in order to ensure the orderly rolling of the steel barrels placed on the storage platform 11 and ensure that the steel barrels can enter the cutting device 2 in the established position and direction, guide strips 15 for restricting the positions of both ends of the steel barrel are provided on both sides of the inclined slope 14. The guide strips 15 extend along the inclined slope 14 to both ends of the storage platform 11, and the guide strips 15 do not interfere with the first blocking unit 12 on the side of the storage platform 11.

[0036] As Figure 1As shown in the figure, two sets of first blocking units 12 are provided, and the two sets of first blocking units 12 are symmetrically arranged on opposite sides of the storage platform 11 along the steel barrel conveying direction. The first blocking unit 12 is provided with a first blocking block 121 and a first driving member 123 for driving the first blocking block 121 to move towards the storage platform 11. The first driving member can be a cylinder, and the telescopic shaft of the cylinder is connected to the first blocking block 121 to drive the first blocking block 121 to perform telescopic movement. Both ends of the first blocking block 121 are provided with stop portions 122 protruding towards the storage platform. By synchronously blocking with the two sets of first blocking units 12, the impact resistance of the first blocking unit 12 against the rolling of the steel barrel is improved, thereby improving the stability and service life of the first blocking unit 12; at the same time, the occurrence of skewing of the steel barrel due to force on one side is avoided. The steel barrels are stacked in sequence on the storage platform 11, and there is a gap between two adjacent steel barrels. When the first driving member 123 drives the first blocking block 121 to move towards the storage platform 11, the stop portions 122 extend into the gaps between the two adjacent steel barrels above and below, and the steel barrels can be blocked from rolling. When the first driving member 123 drives the first blocking block 121 to retract, the stop portions 122 withdraw from the gaps between the two adjacent steel barrels above and below, and the steel barrels can roll along the inclined slope of the storage platform 11.

[0037] As Figure 1 shown, the second blocking unit 13 includes a second driving member located below the storage platform 11. The second driving member can be a cylinder, and a second blocking block 131 connected to the telescopic shaft of the cylinder. The inclined slope 14 is provided with a rectangular hole 141, and the second blocking block 131 is aligned with the rectangular hole 141. The cylinder can drive the second blocking block 131 to extend or retract into the rectangular hole 141. The steel barrel to be processed near the feeding port of the cutting device 2 on the storage platform 11 is blocked by the second blocking unit 13. The second blocking block 131 is arranged in the rectangular hole 141. When the second driving member drives the second blocking block 131 to rise out of the inclined slope 14, the second blocking block 131 plays a blocking role. When the second driving member drives the second blocking block 131 to retract into the rectangular hole 141, the second blocking block 131 releases the steel barrel.

[0038] As Figure 3 shown, the cutting device 2 includes a frame 24. The frame 24 is provided with a clamping mechanism 21 for clamping and positioning the steel barrel, and an end cover cutting mechanism 22 located above the clamping mechanism 21 and a transverse cutting mechanism 23 for cutting the side wall of the steel barrel. After the steel barrel enters the cutting device 2, the clamping mechanism 21 clamps and positions the steel barrel and raises it to the cutting position. The transverse cutting mechanism 23 first performs the task of cutting the side wall of the steel barrel, and then the end cover cutting mechanism 22 performs the task of cutting the end cover.

[0039] As Figure 3 and Figure 4As shown in the figure, the clamping mechanism 21 includes two relatively arranged chucks 211. One of the chucks 211 is connected to a third driving member 212 through a sliding mechanism. The third driving member 212 can drive the sliding mechanism to drive the chucks 211 to approach or move away from each other. The chucks 211 are rotatably installed on the slider, and the bottom of the slider is connected to a fourth driving member 213. The fourth driving member 213 can drive the chucks 211 to lift synchronously. The end cover cutting mechanism 22 is provided with a cutting disc 221 and a fifth driving member for driving the cutting disc 221 to rotate. The fifth driving member is installed on the side of the frame. Both the third driving member 212 and the fourth driving member 213 are cylinders, and the fifth driving member is a rotary motor. The third driving member 212 drives the chucks 211 to clamp the steel barrel from both ends of the steel barrel. The end cover of the steel barrel has a groove. The chuck 211 includes a positioning disc and a first toothed disc fixedly connected to the positioning disc. During the clamping process, the positioning disc on one side extends into the groove and abuts against the groove, and the positioning disc on the other side extends into the interior of the barrel body and abuts against the inner surface of the barrel body. The end parts at both ends of the steel barrel respectively abut against the first toothed disc. After the steel barrel is clamped, the fourth driving member 213 drives the chucks 211 to rise synchronously with the steel barrel to the cutting and processing position. The cutting disc 221 includes a cutter disc and a second toothed disc fixedly connected to the cutter disc. After the chuck rises, the first toothed disc and the second toothed disc are meshed and connected. The cutter disc and the positioning disc form a shearing structure. The fifth driving member drives the second toothed disc to rotate and drives the chuck and the steel barrel to rotate through the first toothed disc. During the rotation process, the cutter disc and the positioning disc form a shearing structure to cut off the end cover of the steel barrel.

[0040] As Figure 3 shown in the figure, the transverse cutting mechanism 23 includes a cutter 231, a sixth driving member 232, a mounting plate 233, and a seventh driving member 234. The sixth driving member 232 is arranged on the mounting plate 233. The cutter 231 is connected to the output end of the sixth driving member 232. The sixth driving member 232 can drive the cutter 231 to perform a reciprocating linear motion. The mounting plate 233 is connected to the output end of the seventh driving member 234. The seventh driving member 234 can drive the mounting plate 233 to lift. In this embodiment, the sixth driving member 232 and the seventh driving member 234 can adopt existing driving technologies, such as the driving methods of cylinders or oil cylinders; the cutter 231 is a laser cutter. Before shearing the bottom and the cover of the steel barrel, the transverse cutting mechanism 23 is first used to cut the side wall of the steel barrel. Before the steel barrel enters the clamping mechanism 21, the cutter 231 is at the top of the frame 24 to avoid affecting the rolling of the steel barrel onto the cutting device 2; when the steel barrel is clamped and lifted, the seventh driving member 234 drives the mounting plate to move downward so that the cutter 231 approaches the steel barrel. When the cutter 231 moves down to the position, the sixth driving member 232 drives the cutter 231 to move along the side wall of the steel barrel to cut open the side wall of the steel barrel; after the cutting is completed, the seventh driving member 234 drives the mounting plate 233 to move upward so that the cutter 231 returns to the original position.

[0041] As Figure 1As shown in the figure, a tilting mechanism 4 is further provided between the two clamping plates 211. The tilting mechanism 4 includes a top tilting plate 41 rotatably mounted on the machine frame 24, and an eighth driving member 42 located below the top tilting plate 41 and drivingly connected to the top tilting plate 41. The eighth driving member 42 can drive the top tilting plate 41 to rotate so that the side of the top tilting plate 41 close to the steel drum extends into the cut seam on the side wall of the steel drum. The eighth driving member 42 can adopt a cylinder, and the end of the telescopic shaft of the cylinder is rotatably connected to the top tilting plate 41. After the transverse cutting mechanism 23 cuts the side wall of the steel drum, the second gear disk rotates and drives the clamping plate 211 and the steel drum to rotate. The end cover cutting mechanism 22 starts cutting the end cover of the steel drum from the cut seam on the side wall. Since the end cover is gradually cut, the side wall of the steel drum and the end cover are gradually separated, and the separated steel plate at the cut seam tilts up. The eighth driving member 42 drives the top tilting plate 41 to extend into the cut seam on the side wall of the steel drum and tilt up the separated steel plate. During the rotation of the steel drum, the cut side wall steel plate slides along the top tilting plate 41 into the flattening mechanism 3. As the steel drum rotates, the end cover of the steel drum is completely cut off, and the side wall steel plate is also completely fed into the flattening mechanism 3 for flattening.

[0042] As Figure 2 shown in the figure, the flattening mechanism 3 includes two flattening rollers 31 arranged in parallel and rotatably. There is a gap between the two flattening rollers 31 for the cut barrel body steel plate to pass through. The flattening rollers 31 are driven to rotate by a driving motor installed on their sides. The cutting port of the side wall steel plate of the steel drum is fed between the two flattening rollers 31 along the top tilting plate 41. After being preliminarily flattened by the flattening rollers, the original cylindrical shape is changed and it is initially transformed into a flat steel plate, and then further processing is carried out.
