Description

Technical Field

[0001] This invention belongs to the field of steel portable dangerous goods packaging box processing technology, and particularly relates to a steel portable dangerous goods packaging box processing equipment. Background Technology

[0002] Steel-framed dangerous goods containers, such as "European-style oil drums," typically refer to liquid storage containers that conform to European standards or common European styles. They are primarily used in industrial settings for storing and transporting liquids such as oils, chemical raw materials, and coatings. Their core characteristic is a high degree of standardization, and they are widely used in Europe and globally. The most typical size for a European-style oil drum is 200 liters (approximately 44 imperial gallons or 53 US gallons), which is the internationally recognized "standard round drum" (although not unique to Europe, it is extremely common there). In contrast, American-style oil drums are traditionally 55 US gallons (approximately 208 liters), with similar but slightly different capacities.

[0003] The steel-handled dangerous goods packaging box has multiple ring-shaped reinforcing ribs (rolled edges) on its body to improve its pressure resistance.

[0004] Existing processing equipment for steel-handled dangerous goods packaging boxes only trims the reinforced rolled welds on the two halves of the oil drum after welding, and only partially trims these welds, resulting in poor trimming quality. Furthermore, the rolling and welding of the two halves of the oil drum are completed on separate equipment, reducing efficiency.

[0005] Integrating the equipment for edge curling and trimming the finished welded edges, and increasing the equipment's trimming range for welded edges on oil drums, would effectively solve the above problems. Summary of the Invention

[0006] Based on this, it is necessary to address the problems existing in current European-style oil drum processing equipment by providing a steel-handled dangerous goods packaging box processing equipment. This invention effectively integrates the oil drum processing steps through a first edge-rolling assembly, a second edge-rolling assembly, a first trimming assembly, and a second trimming assembly, thereby effectively improving the efficiency of oil drum processing.

[0007] The above objectives are achieved through the following technical solutions: A steel-handled dangerous goods packaging box processing equipment, used for processing European-style oil drums, comprising: Two gripping components are located on the upper and lower sides of the platform to simultaneously grip the two halves of the oil drum from the upper and lower sides of the platform and to position the two halves during the welding edge concave and outward rolling process.

The first edge-rolling component has the structural feature of simultaneously processing concave and outward-rolled welding edges on the edges of the two halves along the curve direction of the two halves.

[0009] Two second edge-rolling components are set on the upper and lower sides of the platform to adjust the warping of the welding edge of the two halves so as to accommodate the welding filler during welding. The second edge-rolling components have the structural feature of adjusting the warping of the upper welding edge of the half along the curve direction of the welding edge.

[0010] Two first trimming components and two second trimming components are set on the platform and distributed longitudinally along the platform, respectively, for trimming the welded edges of the completed oil drum. The first trimming components and the second trimming components have the structural feature of trimming most of the welded edges, except for the welded edges near the oil nozzle on the oil drum, along the welded edges of the two halves of the oil drum. The structure of the first trimming component is the same as that of the second trimming component.

[0040] In a further embodiment, such as Figures 10-14 As shown, the second guide seat 501 of the second trimming component 600 is slidably disposed in the first guide seat 109 on the platform 101 along the longitudinal direction of the platform 101. The two first trimming components 500 and the two second trimming components 600 are respectively located on the four sides of the positioning groove 104 on the platform 101 for positioning and placing the oil drum 105. The two second guide seats 501 of the two second trimming components 600 are provided with positioning components 800 for pressing down and positioning the oil drum 105 when the first trimming components 500 and the second trimming components 600 trim the welding edge 107 of the oil drum 105. The positioning component 800 includes a second mast 801 connecting the two second guide seats 501 of the two second trimming components 600. The second mast 801 is provided with a vertically telescopic third hydraulic cylinder 802. The movable end of the third hydraulic cylinder 802 is provided with a positioning plate 803 that cooperates with the oil drum 105.

[0041] In a further embodiment, such as Figure 13 , Figure 14As shown, the drive assembly 700 includes two second screws 701 that are rotatably mounted on the first guide seats 109 in the two second trimming assemblies 600 and threadedly connected to the corresponding second guide seats 501. The two second screws 701 are each provided with a twentieth gear 702 on the same side end. The two twentieth gears 702 mesh with two twentieth gears 703 on the eighth rotating shaft 704. The eighth rotating shaft 704 is rotatably mounted on the platform 101. The eighth rotating shaft 704 is provided with a twentieth gear 705. The twentieth gear 705 meshes with the twentieth gear 706 on the output shaft of the seventh motor 707 on the platform 101.

[0042] This invention integrates a structure for curling the edges 107 of the welded edges of the two halves 106 forming the oil drum 105 and a structure for trimming the welded edges 107 of the oil drum 105 after welding at the welded edges 107, thus concentrating the processing steps of the oil drum 105 and effectively improving the processing efficiency of the oil drum 105. The first edge-curling assembly 300 in this invention can initially curl the edges 107 of the welded edges of the two halves 106 forming the oil drum 105, while the second edge-curling assembly 400 warps and trims the edges 107 of the welded edges of the two halves 106 of the oil drum 105, facilitating the formation of an annular groove on the outer side of the two halves 106 after merging to accommodate the welding filler 108, effectively improving the welding strength of the two halves 106 of the oil drum 105. The two first trimming components 500 and the two second trimming components 600 in this invention enable the oil drum 105 to complete the trimming of all weld seams 107 near the degreasing nozzle under the positioning of the positioning groove 104 and the positioning component 800 on the platform 101, effectively increasing the trimming range of the weld seams 107 and improving the trimming efficiency of the weld seams 107.

[0043] The operation flow of this invention is as follows: In the initial state, the clamping plates 208 in both gripping assemblies 200 are fully retracted into the corresponding receiving grooves 205 on the inner wall of the corresponding positioning cover 203. There is a large gap between the first pressure roller 319 and the corresponding second pressure roller 320 in the first hemming assembly 300. There is a large axial gap between the third pressure roller 414 and the corresponding fourth pressure roller 415 in the second hemming assembly 400. There is a large gap between the fifth pressure roller 519 in the first trimming assembly 500 and the corresponding sidewall of the positioning groove 104, and the second trimming assembly 600 and the positioning assembly 800 are not in the working position.

[0044] When the oil drum 105 needs to be processed, the two halves 106 of the oil drum 105 are inserted into the two positioning covers 203 of the gripping assembly 200 from the upper and lower sides of the platform 101 with their openings facing each other. The first motors 218 in the two gripping assemblies 200 are started. The two first motors 218 drive the two fifth gears 216 to rotate synchronously through the corresponding sixth gear 217. The two fifth gears 216 in each gripping assembly 200 drive the corresponding first threaded sleeve 209 to rotate through the corresponding second rotating shaft 215, fourth gear 214, third gear 213, first rotating shaft 212, second gear 211, and first gear 210. The first threaded sleeve 209 drives the clamping plate 208 at the end of the corresponding first guide rod 207 to clamp the half 106 of the oil drum 105 inserted into the positioning cover 203.

[0045] Next, the first hydraulic cylinder 202 in the two gripping components 200 is activated. The two first hydraulic cylinders 202 drive the two halves 106 to move towards each other by a certain amplitude through the two positioning covers 203, so that the edges of the two halves 106 respectively enter the position between the first pressure roller 319 and the corresponding second pressure roller 320 on the two first seats 312 in the corresponding side part of the first edge rolling component 300. Then, the third motors 326 on the four first seats 312 in the first edge-rolling assembly 300 are started. The four third motors 326 drive the corresponding first pressure rollers 319 and second pressure rollers 320 to move towards each other along the normal direction of the side wall of half 106 through the corresponding twelfth gear 325, eleventh gear 324, first worm 323, first worm wheel 322, fifth rotating shaft 321, tenth gear 316, two first racks 311, two first slides 317 and two first fixing pins 318, respectively. The first pressure rollers 319 and second pressure rollers 320 on each first seat 312 press the welded edge 107 of the half 106 at the corresponding position of the edge. Then, the second motor 301 in the first hemming assembly 300 is started. The second motor 301 drives the two second guide sleeves 306 to rotate synchronously by 180 degrees through the third rotating shaft 302, the seventh gear 303, the eighth gear 304, and the fourth rotating shaft 305. The two second guide sleeves 306 drive the two first pivot pins 309 to move along the corresponding first guide groove 102 through the corresponding two slide rods 307. The first pivot pins 309 drive the corresponding ninth gear 310 to rotate under the action of the corresponding first rack 311. The two slide rods 307 in each second guide sleeve 306 reciprocate under the combined action of the first guide groove 102 and the force spring 308. The cooperation between the force spring 308, the ninth gear 310 and the first rack 311 can ensure that the first pivot pin 309 moves effectively along the first guide groove 102 under the swing of the slide rod 307. The first pivot pin 309 drives the first pressure roller 319 and the second pressure roller 320 on the first seat 312 to continuously press the concave and convex welding edge 107 along the curved direction of the edge of half 106. During the pressing of the welding edge 107 on the edge of half 106 by the first pressure roller 319 and the second pressure roller 320 on the first seat 312, the first seat 312 drives the corresponding first pivot pin 309 to rotate adaptively under the mutual squeezing action of the first pressure roller 319 and the second pressure roller 320 and the edge of half 106.

[0046] After the two second guide sleeves 306 drive the two first seats 312 to rotate more than 180 degrees through the corresponding two slide rods 307, the first edge rolling assembly 300 can complete the pressing and forming of the welding edges 107 of the two halves 106 of the two oil drums 105, and the edges of the formed welding edges 107 are in a horizontal state.

[0047] Next, the third motor 326 on the four first seats 312 is started. The third motor 326 drives the first pressure roller 319 and the second pressure roller 320 on the corresponding first seats 312 to synchronously separate and detach from the welding edge 107 formed by the edge of the half 106 of the oil drum 105 through a series of transmissions. Then, the two first hydraulic cylinders 202 in the gripping assembly 200 are activated to drive the two halves 106 that have been pressed and formed by welding edge 107 to move in opposite directions in the vertical direction by a certain amplitude, so that the welding edge 107 formed by the edges of the two halves 106 is horizontally opposite to the third pressure roller 414 and the fourth pressure roller 415 in the corresponding side of the second edge rolling assembly 400. The upper side of the horizontal edge of the welding edge 107 is exactly flush with the lowermost side of the third pressure roller 414 in the second edge rolling assembly 400. The fifth motor 420 corresponding to the third pressure roller 414 in the second edge rolling assembly 400 is activated first. The fifth motor 420 drives the third pressure roller 414 to move horizontally axially into the groove of the welding edge 107 on the half 106 through the fifteenth gear 419, the fourteenth gear 418, the second worm 417, the second worm wheel 416, the second threaded sleeve 412 and the second guide rod 413. The outer circle of the third pressure roller 414 forms a pressure against the horizontal part of the welding edge 107. Then, the fifth motor 420 corresponding to the fourth pressure roller 415 is started. The fifth motor 420 drives the fourth pressure roller 415 to move horizontally to the third pressure roller 414 through the fifteenth gear 419, the fourteenth gear 418, the second worm gear 417, the second worm wheel 416, the second threaded sleeve 412, and the second guide rod 413. The conical surface of the fourth pressure head and the conical surface of the tail of the third pressure roller 414 warp and bend the horizontal part of the welding edge 107. The fourth motor 407 in the second edge-rolling assembly 400 is started to drive the two corresponding thirteenth gears 406 to rotate. The two thirteenth gears 406 divide... Under the action of the corresponding third rack 408, the second slide 401 and the second seat 404 move along the second guide groove 103. The second seat 404 drives the third pressure roller 414 and the fourth pressure roller 415 on the third seat 409 to move synchronously along the second guide groove 103 and press the horizontal part of the welding edge 107 of half 106 with warping and bending. The warping and bending pressing of the horizontal part of the welding edge 107 can ensure that after the two halves 106 are merged, an annular V-shaped groove for accommodating welding machine filler can be formed on the edge of the welding edge 107, ensuring the firmness of the welding of the two halves 106.

[0048] After the second edge-rolling assembly 400 completes the secondary pressing of the welded edge 107 on the edge of half 106 along the second guide groove 103, the two fifth motors 420 in the second edge-rolling assembly 400 are started one after another. The two fifth motors 420 drive the fourth pressure roller 415 and the third pressure roller 414 to reset and disengage from the welded edge 107 on half 106 of oil drum 105.

[0049] Then, the two halves 106 of the oil drum 105 are removed from the two positioning covers 203 in the gripping assembly 200 and aligned and welded. Before removal, the two first motors 218 are activated to drive the clamps 208 on the inner walls of the two positioning covers 203 to release them. After welding, the two halves 106 form a complete oil drum 105 and two annular grooves are formed in the middle of the oil drum 105, which can effectively enhance the strength of the oil drum 105. At this time, the weld seam in the middle of the completed oil drum 105 protrudes from the wall surface of the oil drum 105 due to the extra size of the edge of the half 106 of the welding filler 108.

[0050] The newly welded semi-finished oil drum 105 is placed into the positioning slot 104 on the platform 101. Then, the seventh motor 707 in the drive assembly 700 is started. The seventh motor 707 drives the drive assembly 700 to run and drive the two second trimming components 600 to move horizontally along the longitudinal direction of the platform 101 to both sides of the two side walls of the oil drum 105 that are distributed laterally along the platform 101. The positioning plate 803 in the positioning assembly 800 is exactly above the oil drum 105. Next, the third hydraulic cylinder 802 is started to drive the positioning plate 803 to move downward and form a clamping and positioning on the oil drum 105.

[0051] Next, as Figure 11 and Figure 12 As shown, the second hydraulic cylinders 512 in the two first trimming components 500 and the two second trimming components 600 are activated. The second hydraulic cylinders 512 drive the two fifth pressure rollers 519 on the two corresponding rocker arms 517 through the corresponding fourth slides 511 and C-shaped seats 514 to press into the two grooves formed by the welded edge 107 on the oil drum 105, so that the welded part of the welded edge 107 is inserted into the groove in the middle of the fifth pressure roller 519. Then, the sixth motor 510 in the first trimming component 500 and the second trimming component 600 is activated. The sixth motor 510 drives the two corresponding fifth pressure rollers 519 to reciprocate horizontally. The horizontally moving fifth pressure rollers 519 deburr the two annular grooves and welded parts formed in the middle of the oil drum 105 and push the part of the welded part that protrudes from the side wall of the oil drum 105 into the oil drum 105, ensuring that the oil drum 105 can stand upright normally.

[0052] When the two fifth pressure rollers 519 in the first trimming assembly 500 or the second trimming assembly 600 move to the corner of the oil drum 105, as the two fifth pressure rollers 519 continue to move along the welded edge 107 of the oil drum 105, the second hydraulic cylinder 512 is activated to drive the two fifth pressure rollers 519 to squeeze towards the oil drum 105. Under the combined action of the edge of the oil drum 105 and the corresponding spiral spring 516, the two fifth pressure rollers 519 drive the swing arm 517 to swing adaptively and continue to trim the groove and welded edge 107 weld seam at the corner of the oil drum 105, thereby ensuring that the first trimming assembly 500 and the second trimming assembly 600 can effectively trim all welded edge 107 weld seams and grooves on the oil drum 105 except for the welded edge 107 near the oil nozzle.

[0053] After the welding edge 107 in the middle of the oil drum 105 is trimmed, the sixth motor 510 and the second hydraulic cylinder 512 in the first trimming assembly 500 and the second trimming assembly 600, the seventh motor 707 in the drive assembly 700 and the third hydraulic cylinder 802 in the positioning assembly 800 are started to reset the two first trimming assemblies 500 and the two second trimming assemblies 600.

[0054] After the first trimming component 500 and the second trimming component 600 have completed their reset, the trimmed oil drum 105 can be removed from the positioning groove 104.
