Description

Technical Field

[0001] The present invention relates to the technical field of cutting machines, and in particular to a barrel lid cutting device for steel barrel refurbishment. Background Art

[0002] As a traditional container, steel barrels play an important role in multiple fields, especially in the chemical, petroleum, food, and logistics industries; with their characteristics of being sturdy, durable, having good sealing performance, being reusable, and being easy to handle, they have become the preferred containers for storing and transporting various liquid and solid products; however, during the industrial production process, when the liquid in the steel barrel is used up, a large number of waste steel barrels will be generated, and after these waste steel barrels are used up, they generally need to be recycled and refurbished for reuse to achieve the purpose of sustainable recycling.

[0003] Currently, when recycling and using these waste steel barrels, in order to reduce the volume and facilitate stacking and transportation, workers usually use a vertical semi-automatic barrel lid cutting machine to cut the barrel lid from the barrel body; however, when the existing vertical semi-automatic barrel lid cutting machine cuts a steel barrel, it is necessary for workers to first use a hammer or other knocking tools to flatten the oil port on the barrel lid, and then start the vertical semi-automatic barrel lid cutting machine to cut the steel barrel according to a preset path until the barrel lid is cut from the barrel body. In this way, the cutting of the barrel lid can be completed. However, in the above method, when operating, since it is necessary for workers to use a hammer or other knocking tools to flatten the oil port on the barrel lid, it is not only time-consuming and laborious, but also has low efficiency, and it is difficult to cut the barrel lid on a deformed steel barrel using the existing vertical semi-automatic barrel lid cutting machine. Once the steel barrel has a depression, it is easy to cause the barrel lid of the steel barrel to be uneven, resulting in an incomplete cutting of the barrel lid when the subsequent vertical semi-automatic barrel lid cutting machine cuts the steel barrel according to the preset path. Summary of the Invention

Detailed implementation manners

[0027] The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which the currently preferred embodiments of the present invention are shown. However, the present invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and to fully convey the scope of the present invention to those skilled in the art.

[0028] Embodiment: A barrel lid cutting device for steel barrel renovation, see Figures 1 - 5 as shown, which includes a fixing frame 1 and a vertical semi-automatic barrel lid cutting machine 2; the vertical semi-automatic barrel lid cutting machine 2 is installed at the rear side of the top of the fixing frame 1, and the vertical semi-automatic barrel lid cutting machine 2 is used for cutting the barrel lid of the steel barrel;

[0029] It further includes a support disc 3, an air pump 4, a hose 5, a rigid pipe 6, a hydraulic cylinder 7, a pressing plate 8, a lifting mechanism and a limiting mechanism; the support disc 3 is slidably arranged inside the fixing frame 1, and the support disc 3 is used for supporting the steel barrel, the upper end of the support disc 3 is concave, so that when the steel barrel is placed on the support disc 3, the concave shape at the upper end of the support disc 3 can be used to limit the lower end of the steel barrel to prevent the steel barrel from disengaging from the support disc 3; the air pump 4 is installed at the rear side of the top of the fixing frame 1, and the air pump 4 is located on the left side of the vertical semi-automatic barrel lid cutting machine 2; one end of the hose 5 is communicated with the air outlet of the air pump 4; the other end of the hose 5 is communicated with a rigid pipe 6; four hydraulic cylinders 7 are installed at intervals on the outer wall of the rigid pipe 6; the pressing plate 8 is installed between the telescopic rods of the four hydraulic cylinders 7, the rigid pipe 6 passes through the middle of the pressing plate 8 in a contact manner, and the pressing plate 8 is used for flattening the oil port on the barrel lid; the lifting mechanism is used for driving the support disc 3 to lift, so that the support disc 3 can bring the steel barrel into the fixing frame 1; the limiting mechanism is used for limiting the rigid pipe 6 at the oil port of the barrel lid to prevent the rigid pipe 6 from disengaging from the oil port of the barrel lid.

[0030] Refer to Figure 2 As shown, the lifting mechanism includes a servo motor I 9 and a lead screw 10; four servo motors I 9 are arranged at intervals at the inner bottom of the fixed frame 1; four lead screws 10 are rotatably arranged at intervals inside the fixed frame 1, and the bottom ends of the four lead screws 10 are respectively connected to the output shafts of the four servo motors I 9, and the support disc 3 is threadedly connected to the lead screw 10, so that when the servo motor I 9 drives the lead screw 10 to rotate forward and backward, the lead screw 10 can drive the support disc 3 to lift and lower.

[0031] Refer to Figure 4 and Figure 5 As shown, the limiting mechanism includes an electric push rod 11, a pressing block 12, a cross frame 13, a clamping block 14 and a spring 15; the electric push rod 11 is arranged inside the hard pipe 6; the pressing block 12 is connected to the telescopic rod of the electric push rod 11, and both the left and right sides of the pressing block 12 are inclined planes; the cross frame 13 is installed inside the hard pipe 6, and the cross frame 13 is located directly below the electric push rod 11; two clamping blocks 14 are symmetrically arranged and slidably arranged inside the cross frame 13. When the pressing block 12 moves downward and contacts the clamping block 14, the pressing block 12 can use the inclined plane to squeeze the two clamping blocks 14 to move away from each other, so that the clamping blocks 14 extend out of the hard pipe 6; both ends of the spring 15 are respectively connected to the cross frame 13 and the clamping block 14.

[0032] During use, place the waste steel barrel upright on the support disc 3, then insert the lower end of the hard pipe 6 into the waste steel barrel through the oil port, and then drive the pressing block 12 to move downward through the electric push rod 11. When the inclined plane of the pressing block 12 contacts the clamping block 14, the pressing block 12 will use the inclined plane to squeeze the clamping block 14 to move away from each other, and the spring 15 stretches (as Figure 5As shown, the clamping block 14 is extended from the rigid pipe 6. In this way, the lower end of the rigid pipe 6 can be clamped inside the waste steel barrel by the limit of the clamping block 14. After that, the rigid pipe 6 is released, and the rigid pipe 6, the hydraulic cylinder 7 and the pressing plate 8 fall downward under the action of gravity until the pressing plate 8 contacts the oil port of the waste steel barrel. Then, the telescopic rod of the hydraulic cylinder 7 is controlled to extend. At this time, the oil port of the waste steel barrel will squeeze the hydraulic cylinder 7, the rigid pipe 6, the cross frame 13 and the clamping block 14 upward by using the pressing plate 8 until the clamping block 14 contacts the bottom end of the barrel cover, so that the clamping block 14 and the pressing plate 8 clamp the oil port of the waste steel barrel. After that, when the telescopic rod of the hydraulic cylinder 7 continues to extend, the pressing plate 8 will gradually flatten the oil port of the waste steel barrel. In this way, the oil port of the waste steel barrel can be automatically flattened. After the oil port of the waste steel barrel is flattened, the telescopic rod of the hydraulic cylinder 7 is controlled to stop extending. Then, the servo motor I 9 is used to drive the lead screw 10 to rotate, so that the support plate 3 gradually moves downward, and the waste steel barrel on the support plate 3 is also moved downward into the fixed frame 1 together, so that the waste steel barrel is limited in the fixed frame 1. After that, the air pump 4 is used to convey air into the waste steel barrel through the hose 5 and the rigid pipe 6 until the inside of the waste steel barrel is filled with gas, so that the gas can expand the deformed and sunken parts of the waste steel barrel, and the deformed and sunken parts of the waste steel barrel gradually return to their original state. In this way, the barrel cover of the waste steel barrel can gradually return to the horizontal state, so that the vertical semi-automatic barrel cover cutting machine 2 can cut the barrel cover of the waste steel barrel according to the preset path. During this period, if the waste steel barrel swings due to inflation, the limit of the fixed frame 1 can prevent the waste steel barrel from detaching from the support plate 3. After the barrel cover of the waste steel barrel returns to the horizontal state, the servo motor I 9 is used to drive the lead screw 10 to reverse and reset, so that the support plate 3 and the waste steel barrel gradually move upward and reset. Then, the telescopic rod of the hydraulic cylinder 7 is controlled to shorten. At this time, the hydraulic cylinder 7, the rigid pipe 6, the cross frame 13 and the clamping block 14 fall downward under the action of gravity, and the clamping block 14 gradually separates from the bottom end of the barrel cover. After that, the telescopic rod of the hydraulic cylinder 7 is controlled to stop shortening. Then, the electric push rod 11 is used to drive the pressing block 12 to move upward and reset. When the inclined surface of the pressing block 12 separates from the clamping block 14, the spring 15 returns to its original state, and the spring 15 drives the pressing block 12 to move toward the side close to each other to reset, so that the clamping block 14 retracts into the rigid pipe 6. Subsequently, the rigid pipe 6 is taken out from the oil port of the waste steel barrel, and the pressing plate 8 is separated from the oil port of the waste steel barrel. After that, the vertical semi-automatic barrel cover cutting machine 2 can cut the barrel cover of the waste steel barrel according to the preset path. After the barrel cover of the waste steel barrel is cut, the waste steel barrel is turned over 180 degrees, and then the vertical semi-automatic barrel cover cutting machine 2 can cut the bottom cover at the other end of the waste steel barrel according to the preset path. After the bottom cover at the other end of the waste steel barrel is cut, the waste steel barrel is taken out from the support plate 3.

[0033] See Figures 6 - 8As shown in the figure, the barrel cover cutting device for steel barrel renovation further includes a flushing mechanism. The flushing mechanism includes a water frame 16, a funnel 17, bolts 18, a water pump 19, a spray pipe 20, a filter screen 22, a supporting basket 23 and an oil-absorbing filter bag 24. The water frame 16 is installed on the lower side inside the support plate 3. The funnel 17 is detachably installed on the upper side inside the support plate 3, and the funnel 17 is located above the water frame 16. Four bolts 18 are symmetrically installed between the funnel 17 and the support plate 3 in a left-right symmetrical manner by threading, and the bolts 18 are used to fix the funnel 17 on the support plate 3. Two water pumps 19 are symmetrically installed in the front and back inside the water frame 16. One end of the spray pipe 20 is communicated with the water outlet of the water pump 19. Spray nozzles 21 are symmetrically arranged on the front and back of the funnel 17, and the other end of the spray pipe 20 is communicated with the spray nozzles 21. A filter screen 22 is installed on the funnel 17, and the filter screen 22 is used to filter out impurities in the oil-water mixture. The supporting basket 23 is installed at the bottom end of the funnel 17 by threading. The oil-absorbing filter bag 24 is placed inside the supporting basket 23, and the oil-absorbing filter bag 24 is used to separate the oil and water.

[0034] During use, the bolts 18 can be rotated and removed, and then the funnel 17 together with the supporting basket 23 can be taken out from the support plate 3. After that, clean water is added to the water frame 16, and then the funnel 17 together with the supporting basket 23 is put back into the support plate 3, and then the bolts 18 are rotated back in the reverse direction. When the vertical semi-automatic barrel cover cutting machine 2 cuts the bottom cover at the other end of the waste steel barrel according to the preset path, the clean water in the water frame 16 can be pumped into the spray pipe 20 and the spray nozzles 21 through the water pump 19, so that the clean water is sprayed from the spray nozzles 21 into the interior of the waste steel barrel (at this time, the barrel cover of the waste steel barrel has been cut off, so the clean water can be directly sprayed into the interior of the waste steel barrel for flushing), thereby flushing the interior of the waste steel barrel. The oil-water mixture flushed from the interior of the waste steel barrel will fall downward onto the filter screen 22. At this time, the filter screen 22 will filter the oil-water mixture, so as to filter out the impurities in the oil-water mixture, and the oil-water mixture will fall into the funnel 17 through the filter screen 22. Subsequently, the oil-water mixture will be concentrated and fall into the oil-absorbing filter bag 24 through the funnel 17, so that the oil-absorbing filter bag 24 separates the oil and water, so that the oil remains in the oil-absorbing filter bag 24, and the water passes through the oil-absorbing filter bag 24 and falls back into the water frame 16. In this way, it can automatically flush the interior of the waste steel barrel and collect and separate the oil-water mixture generated after cleaning. After the waste steel barrel is taken out from the support plate 3, the impurities on the filter screen 22 are cleaned. Then, the bolts 18 can be rotated and removed again, and then the funnel 17 together with the supporting basket 23 can be taken out from the support plate 3. After that, the supporting basket 23 is rotated and removed, and then the oil-absorbing filter bag 24 is removed for replacement. After the oil-absorbing filter bag 24 is replaced, the supporting basket 23 is rotated back to its original position, and then the funnel 17 together with the supporting basket 23 is put back into the support plate 3, and the bolts 18 are rotated back in the reverse direction.

[0035] See Figure 9 and Figure 10As shown in the figure, the barrel cover cutting device for steel barrel renovation further includes a flipping mechanism, which includes a bracket 25, a reduction motor 26, a rotating frame 27, a servo motor II 28, clamping plates 29 and rubber strips 30; the bracket 25 is installed on the right side of the top of the fixed frame 1; the reduction motor 26 is installed on the upper right side of the bracket 25; the rotating frame 27 is rotatably arranged on the upper side of the bracket 25, and the rotating frame 27 is connected to the output shaft of the reduction motor 26; two servo motors II 28 are symmetrically arranged front and back on the lower side of the rotating frame 27; two clamping plates 29 are rotatably arranged front and back on the upper side of the rotating frame 27, and the two clamping plates 29 are respectively connected to the output shafts of the two servo motors II 28, and the clamping plates 29 are used to clamp the steel barrel; rubber strips 30 are arranged at intervals on the side of the two clamping plates 29 close to each other, and the rubber strips 30 are used to tightly adhere to the outer wall of the steel barrel, so as to increase the friction between the clamping plates 29 and the steel barrel.

[0036] When it is necessary to flip the waste steel barrel by 180 degrees, the servo motor II 28 can be used to drive the clamping plate 29 to rotate until the rubber strip 30 on the clamping plate 29 contacts the outer wall of the waste steel barrel, so that the clamping plate 29 uses the rubber strip 30 to clamp the waste steel barrel. Subsequently, the servo motor I 9 is used to drive the lead screw 10 to rotate, so that the support plate 3 moves downward, so that the support plate 3 does not affect the flipping of the waste steel barrel. After that, the reduction motor 26 is used to drive the rotating frame 27 to rotate 180 degrees, so as to drive the servo motor II 28, the clamping plate 29, the rubber strip 30 and the waste steel barrel to rotate 180 degrees, thereby driving the waste steel barrel to flip. After the waste steel barrel is flipped, the servo motor I 9 is used to drive the lead screw 10 to reverse and reset, so that the support plate 3 moves upward and resets, so that the support plate 3 supports the waste steel barrel. Then, the servo motor II 28 is used to drive the clamping plate 29 to reverse and reset, so that the rubber strip 30 on the clamping plate 29 is separated from the outer wall of the waste steel barrel, so that the clamping plate 29 releases the waste steel barrel.

[0037] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should be covered within the protection scope of the present invention.
