Description

Technical Field

[0001] The present invention relates to the technical field of steel drum production, and particularly to a trimming device for the production of packaging steel drums. Background Art

[0002] Steel drum trimming is a key process in the production of packaging steel drums, aiming to precisely cut the edges of the formed steel drums to remove excess materials and ensure the flatness and smoothness of the steel drum edges. This process not only affects the appearance quality of the steel drums but also directly relates to the smooth progress of subsequent processes such as capping and painting. Traditional steel drum trimming devices usually include a fixture for fixing the steel drum, a motor for driving the steel drum to rotate, and a cutter for performing the trimming operation.

[0003] However, after the existing steel drum trimming device completes the trimming operation, it is necessary for the operator to manually remove the trimmed steel drum and the trimmed edge materials. This manual operation not only increases the labor intensity of the workers but also significantly reduces the production efficiency. Especially in the process of mass production, the frequent manual blanking step becomes the key bottleneck restricting the production line speed, resulting in low overall production efficiency and being prone to introducing human errors, affecting the consistency and stability of product quality.

[0004] The purpose of the present invention is to solve the problem that after the existing steel drum trimming device finishes the trimming operation on the steel drum, it is necessary to manually remove the trimmed steel drum and the cut edge, resulting in low efficiency of steel drum trimming.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0043] Embodiment 1: As Figures 1 to 16 shown, the present invention provides a trimming device for the production of packaging steel drums, including a bottom plate 1, on which a first support rod 2 and a second support rod 3 are installed, and a flipping mechanism 5 is installed between the second support rod 3 and the first support rod 2;

[0044] The flipping mechanism 5 includes an L-shaped frame 51. The left orthographic projection of the L-shaped frame 51 is an obtuse V shape. The L-shaped frame 51 is fixedly connected with a rotating shaft 54. One end of the rotating shaft 54 is rotatably connected to the first support rod 2, and the other end of the rotating shaft 54 is rotatably connected to the second support rod 3. A first limiting mechanism 52 and a second limiting mechanism 53 are installed in the L-shaped frame 51. The structures and specifications of the first limiting mechanism 52 and the second limiting mechanism 53 are the same. The first limiting mechanism 52 includes an expanding mechanism 521;

[0045] The expanding mechanism 521 includes a cylindrical block 5211. A supporting mechanism 522 is installed on the top of the cylindrical block 5211. A number of sliding blocks 5212 are sleeved outside the cylindrical block 5211. The sliding blocks 5212 are slidably connected to the cylindrical block 5211. A through groove 5217 is opened at the bottom of the sliding block 5212. A supporting block 5213 is arranged in the through groove 5217. A sliding groove 5216 is opened on the side wall of the supporting block 5213. The side wall of the through groove 5217 is arranged in the sliding groove 5216. The side wall of the through groove 5217 is slidably connected to the sliding groove 5216. The supporting block 5213 is fixedly connected to the cylindrical block 5211. A groove 5218 is opened on one side of the sliding block 5212. Connecting blocks 5215 are installed at the bottoms of a number of sliding blocks 5212. A compression spring 5214 is installed between adjacent pairs of connecting blocks 5215. A pressing rod 523 is installed on the side wall of the sliding block 5212. A jacking mechanism 524 is installed at the bottom of the expanding mechanism 521;

[0046] The jacking mechanism 524 includes a cylinder 5241 installed in the L-shaped frame 51 and a plain bearing 5242 installed on one side of the L-shaped frame 51. The bottom of the supporting block 5213 is fixedly connected to the top surface of the plain bearing 5242. One end of the cylinder 5241 passes through the plain bearing 5242 and is arranged in the groove 5218. A tapered block 5243 is fixedly connected to one end of the cylinder 5241;

[0047] The pressing rod 523 includes a second cylinder body 5231. A second groove 5232 is opened on the side wall of the second cylinder body 5231. A first sliding rod 5233 is sleeved inside the second cylinder body 5231. The second cylinder body 5231 is slidably connected to the first sliding rod 5233. One end of the first sliding rod 5233 is hinged to a first frame 5234. An extrusion block 5235 is installed in the first frame 5234. At least one second bolt 5237 is installed on the side wall of the first sliding rod 5233. One end of the second bolt 5237 is arranged outside the second cylinder body 5231 through the second groove 5232. A hook 5236 is fixedly connected to the bottom of the first frame 5234;

[0048] A first servo motor 4 is installed at one end of the rotating shaft 54. The first servo motor 4 is fixedly connected to the first support rod 2. A first sleeve 21 is installed at the top of the first support rod 2. A pressing mechanism 6 is installed inside the first sleeve 21. A cutter mechanism 7 is arranged outside one side of the flipping mechanism 5.

[0049] The first servo motor 4 can drive the turnover mechanism 5. When the steel barrel limited by the first limiting mechanism 52 is being trimmed, one end of the second limiting mechanism 53 inclines downward, so that the steel barrel located in the second limiting mechanism 53 and the cut steel barrel edge can slide out of the second limiting mechanism 53, thereby realizing blanking. After the blanking is completed, the worker reinserts the new steel barrel to be trimmed into the second limiting mechanism 53, and further drives the air cylinder 5241 to make the conical block 5243 extrude the groove 5218, thereby pushing the sliding block 5212 to move outwards, and driving the pressing rod 523 to press and limit the steel barrel.

[0050] The first servo motor 4 can drive the flipping mechanism 5. When the steel barrel limited by the first limiting mechanism 52 is being trimmed, one end of the second limiting mechanism 53 tilts downward, so that the steel barrel located in the second limiting mechanism 53 and the trimmed steel barrel edge can slide out of the second limiting mechanism 53, thus realizing easy blanking. Specifically, the operator sleeved the steel barrel to be processed outside the second limiting mechanism 53. At this time, the first limiting mechanism 52 is in a waiting state, ready to receive the incoming steel barrel. After the new steel barrel is placed, the air cylinder 5241 starts to work. The air cylinder 5241 pushes the tapered block 5243 to move along the plain bearing 5242 and enter the groove 5218 at the bottom of the sliding block 5212. The tapered block 5243 applies pressure to the groove 5218, forcing the sliding block 5212 to slide outward along the cylindrical block 5211. As the sliding block 5212 moves outward, the pressing rod 523 installed on its side wall also expands outward accordingly. The extrusion block 5235 of the pressing rod 523 tightly adheres to the inner wall of the steel barrel, thus realizing the firm fixation of the steel barrel. The lengths of the respective pressing rods 523 can be adjusted individually. When used in conjunction with the sliding block 5212, it can adapt to steel barrels of different specifications, improving the versatility and application range of the equipment. For non-circular steel barrels (such as oval-shaped ones), by pre-adjusting the lengths of the respective pressing rods 523, the steel barrel can be initially positioned, and then combined with the outward sliding of the sliding block 5212, ensuring that even steel barrels with irregular shapes can be firmly clamped, guaranteeing the accuracy of the trimming operation. Since the lengths of the pressing rods 523 can be adjusted individually, the operator can make fine adjustments according to the specific shape and size of the steel barrel, ensuring that the steel barrel can be fixed with the most appropriate force and position each time, thereby improving the processing accuracy. Further, the first servo motor 4 starts, driving the L-shaped frame 51 and the first limiting mechanism 52 and the second limiting mechanism 53 inside it to make appropriate angular adjustments, so that the steel barrel can correctly enter the trimming station. Once the steel barrel is fixed and adjusted to the correct angle, the cutting tool mechanism 7 located on one side of the flipping mechanism 5 starts and cuts the edge of the steel barrel according to the preset path. When the steel barrel in the second limiting mechanism 53 is being trimmed, a steel barrel to be trimmed can be placed in the first limiting mechanism 52. During this process, the support mechanism 522 and the pressing mechanism 6 provide stable support for the entire expanding mechanism 521, ensuring the stability during the trimming process. After trimming is completed, the first servo motor 4 rotates in the reverse direction, causing the rotating shaft 54 to drive one end of the L-shaped frame 51 and the second limiting mechanism 53 inside it to tilt downward. Further, the air cylinder 5241 resets, and the compression spring 5214 between the sliding blocks 5212 contracts due to the loss of external force, helping the sliding blocks 5212 and the pressing rods 523 to quickly reset. Due to the gravity, the trimmed steel barrel and the cut-off edge will naturally slide out of the second limiting mechanism 53, realizing automatic unloading. The sliding out of the steel barrel prepares for the clamping of the next steel barrel. The operator quickly replenishes a new steel barrel into the second limiting mechanism 53, and the entire system immediately enters the next cycle and continues the above work process.The hook 5236 can hold the cut edge of the steel barrel, preventing the cut edge of the steel barrel from falling down, thus facilitating the unloading of the cut edge of the steel barrel.

[0051] The support mechanism 522 includes a first cylinder body 5221. A first lead screw 5223 is sleeved inside the first cylinder body 5221. The first lead screw 5223 is threadedly connected to the first cylinder body 5221. First groove bodies 5222 are formed on both sides of the first cylinder body 5221. One end of the first lead screw 5223 is provided with a rotating block 5226. A first clamping block 5228 is installed on the top of the rotating block 5226. The first clamping block 5228 is arranged inside the first lead screw 5223 and is rotatably connected to the first lead screw 5223. First bolts 5227 are fixedly connected to both sides of the rotating block 5226. One end of each first bolt 5227 is arranged outside the first cylinder body 5221 through the first groove body 5222. One end of the first lead screw 5223 is provided with a first disc block 5224. A first rubber pad 5225 is installed on the top of the first disc block 5224. Before placing the steel barrel on the second limiting mechanism 53, the operator can pre-adjust the position of the first lead screw 5223 according to the size of the steel barrel to adapt to steel barrels of different specifications. This can be achieved by manually rotating the first lead screw 5223 or using power tools, so as to support steel barrels of different specifications. By screwing a bolt into the first bolt 5227 to press the first cylinder body 5221, the limiting of the first lead screw 5223 is realized, preventing the first lead screw 5223 from moving up and down.

[0052] The clamping mechanism 6 includes a second sleeve 61 installed in the first sleeve 21, and a first rod body 63 is sleeved in the second sleeve 61. The first rod body 63 is slidably connected to the second sleeve 61. The first rod body 63 is installed with a limit bar 631, and the second sleeve 61 is provided with a limit groove that cooperates with the limit bar 631. The limit groove is engaged with the limit bar 631. A second screw rod 68 is sleeved in the first rod body 63, and the second screw rod 68 is threadedly connected to the first rod body 63. A second servo motor 62 is installed at one end of the second screw rod 68, and the second servo motor 62 is fixedly connected to the second sleeve 61. A connecting tube 610 is mounted on one end of the first rod 63. A second clamping block 67 is mounted on one end of the first rod 63. The second clamping block 67 is disposed within the connecting tube 610 and is rotatably connected to the connecting tube 610. A belt 65 is mounted on the outer surface of the connecting tube 610. A third servo motor 66 is mounted on one side of the belt 65. The third servo motor 66 is fixedly connected to the first rod 63. The belt 65 is mounted on the outer surface of the rotor of the third servo motor 66. The third servo motor 66 is driven by the belt 65 and the connecting tube 610. A second disc 64 is screwed to the bottom of the connecting tube 610. A second rubber pad 69 is mounted on the bottom of the second disc 64. The second servo motor 62 drives the second screw rod 68 to rotate, which in turn drives the first rod 63 downward, further causing the second disc 64 to press against the steel drum. Since the position of the second disc 64 is adjustable, it can be used to press steel drums of different specifications. The third servo motor 66 is started, and drives the connecting cylinder 610 to rotate through the belt 65. The second disc block 64 at the bottom of the connecting cylinder 610 rotates accordingly, further driving the steel drum to rotate.

[0053] The cutting knife mechanism 7 includes a guide rail 78. On one side of the guide rail 78, a fifth servo motor 713 is installed. The rotor of the fifth servo motor 713 is equipped with a third lead screw 714. A moving block 716 is sleeved outside the third lead screw 714. The moving block 716 is threadedly connected to the third lead screw 714. The moving block 716 is arranged in the guide rail 78 and is slidably connected to the guide rail 78. A second slide bar 715 is sleeved inside the moving block 716. The second slide bar 715 is slidably connected to the moving block 716. One end of the second slide bar 715 is installed with a second frame 710. A cutting knife 711 is installed inside the second frame 710. The cutting knife 711 is rotatably connected to the second frame 710. A spring 79 is sleeved outside the second slide bar 715. One end of the spring 79 is fixedly connected to the second slide bar 715, and the other end of the spring 79 is fixedly connected to the moving block 716. A fourth servo motor 712 is installed on the top of the second frame 710. The rotor of the fourth servo motor 712 is fixedly connected to the cutting knife 711. Before starting the edge cutting operation, the fifth servo motor 713 is started to drive the third lead screw 714 to rotate. Since the third lead screw 714 is threadedly connected to the moving block 716, the rotational motion is converted into a linear motion, causing the moving block 716 to move along the guide rail 78. The fifth servo motor 713 continues to operate, accurately moving the moving block 716 to the predetermined cutting position. At this time, the second slide bar 715 and the second frame 710 also move accordingly, ensuring that the cutting knife 711 accurately aligns with the area of the steel barrel to be edge-cut. The fourth servo motor 712 is started, and its rotor directly drives the cutting knife 711 to rotate. The cutting knife 711 is rotatably connected to the second frame 710, ensuring its stability during rotation. The spring 79 provides a certain elastic support for the second slide bar 715, ensuring that the cutting knife 711 can apply pressure evenly to achieve smooth cutting. The presence of the spring 79 also allows the cutting knife 711 to automatically adjust when encountering slight resistance, avoiding equipment damage or steel barrel deformation caused by excessive pressure.

One end of the second rod body 72 is fixedly connected with a connection head 74. A cross bar 75 is sleeved inside the connection head 74. The cross bar 75 is slidably connected to the connection head 74. A second limit pin 77 is sleeved inside one side of the connection head 74. The second limit pin 77 is threadedly connected to the connection head 74. A positioning block 611 is arranged on one side of the connection cylinder 610. The diameter of the second disc block 64 is longer than that of the connection cylinder 610. By sleeving a mold for the steel barrel to be trimmed on the outside of the connection cylinder 610, the mold will rotate along with the rotation of the steel barrel. Then, through the contact between the second sliding rod 715 and the mold, the second sliding rod 715 can drive the cutting knife 711 to move along the edge of the steel barrel through the second frame body 710. By sleeving a mold matching the steel barrel to be trimmed on the outside, the cutting knife 711 can accurately cut along the edge of the steel barrel. Even for non-standard circular steel barrels, the trimming operation can be successfully completed. This greatly expands the application range of the equipment and improves the production efficiency.

[0055] A ball 76 is installed at one end of the cross bar 75. The ball 76 rolls, thereby reducing the friction between the cross bar 75 and the mold, enabling the cross bar 75 to move more smoothly.

[0056] Specifically, the working principle of the present invention is as follows:

[0057] In the trimming device for the production of packaging steel barrels, first, the cylinder 5241 drives the conical block 5243 into the groove 5218 at the bottom of the sliding block 5212, forcing the sliding block 5212 to slide outward along the cylindrical block 5211. As the sliding block 5212 moves outward, the pressing rod 523 installed on its side wall also expands outward accordingly. The hook 5236 on the pressing rod 523 tightly adheres to the inner wall of the steel barrel, realizing the firm fixation of the steel barrel. The lengths of the respective pressing rods 523 can be adjusted individually. When used in cooperation with the sliding block 5212, it can adapt to steel barrels of different specifications, improving the versatility and application range of the equipment. In addition, the support mechanism 522 and the pressing mechanism 6 provide stable support for the entire expansion mechanism 521, ensuring the stability of the steel barrel during the processing.

[0058] After the steel barrel is firmly fixed, the first servo motor 4 is started to drive the L-shaped frame 51 and the first limiting mechanism 52 and the second limiting mechanism 53 inside it to make appropriate angular adjustments, so that the steel barrel correctly enters the edge trimming station. At this time, the cutting tool mechanism 7 located on one side of the turning mechanism 5 is started, and the fifth servo motor 713 drives the third lead screw 714 to rotate, so that the moving block 716 accurately moves along the guide rail 78 to the predetermined cutting position. The fourth servo motor 712 is started to directly drive the cutting tool 711 to rotate for edge trimming operation. At the same time, the third servo motor 66 drives the connecting cylinder 610 to rotate through the belt 65, and then the second disc block 64 drives the steel barrel to rotate synchronously, ensuring that the cutting tool 711 can perform continuous and stable cutting along the edge of the steel barrel, and even non-standard circular steel barrels can smoothly complete the edge trimming operation.

[0059] After the edge trimming is completed, the first servo motor 4 rotates in the reverse direction, so that the rotating shaft 54 drives one end of the L-shaped frame 51 and the second limiting mechanism 53 inside it to tilt downward, and the steel barrel with the edge trimmed and the cut edge will naturally slide out from the second limiting mechanism 53 to achieve automatic unloading. The air cylinder 5241 resets, and the compression spring 5214 between the sliding blocks 5212 contracts due to the loss of external force, helping the sliding blocks 5212 and the pressing rod 523 to quickly reset. The operator quickly replenishes a new steel barrel into the second limiting mechanism 53, and the entire system immediately enters the next cycle and continues the above work process, thus realizing an efficient and continuous steel barrel edge trimming production process.

[0060] In summary, the present invention solves the problem that the existing steel barrel edge trimming device needs to manually remove the steel barrel with the edge trimmed and the cut edge after the edge trimming operation on the steel barrel, resulting in low efficiency of steel barrel edge trimming.

[0061] It should be understood that in the present invention, terms such as "first" and "second" are used to describe various information, but these information should not be limited to these terms, and these terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present invention, "first" information can also be called "second" information, and similarly, "second" information can also be called "first" information. In addition, the orientation or positional relationship indicated by terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention.

[0062] The above is the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and deformations can still be made, and these improvements and deformations are also regarded as the protection scope of the present invention.
