Description

Technical Field

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

[0002] Steel drum trimming is a key process in the production of packaging steel drums. It aims to accurately cut the edges of the formed steel drums to remove excess material and ensure that the edges of the steel drums are flat and smooth. This process not only affects the appearance quality of the steel drums, but also directly affects whether the subsequent processes such as capping and painting can proceed smoothly. Traditional steel drum trimming devices usually include a clamp to fix the steel drum, a motor to drive the steel drum to rotate, and a cutter to perform the trimming operation.

[0003] However, after the existing steel drum trimming device completes the trimming operation, the operator needs to manually remove the trimmed steel drum and the cut edge material. This manual operation not only increases the labor intensity of the workers, but also significantly reduces production efficiency. Especially in the mass production process, the frequent manual unloading steps become the key bottleneck restricting the production line speed, resulting in low overall production efficiency, and easily introduces human errors, affecting the consistency and stability of product quality.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Embodiment 1: Figures 1 to 16 As shown, the present invention proposes a trimming device for packaging steel barrel production, comprising a bottom plate 1, a first support rod 2 and a second support rod 3 are installed on the bottom plate 1, and a turning mechanism 5 is installed between the second support rod 3 and the first support rod 2; The flip mechanism 5 includes an L-shaped frame 51, the left-view orthographic projection of the L-shaped frame 51 is an obtuse V-shape, the L-shaped frame 51 is fixedly connected to 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, and a first limiting mechanism 52 and a second limiting mechanism 53 are installed in the L-shaped frame 51. The first limiting mechanism 52 and the second limiting mechanism 53 have the same structure and specifications, and the first limiting mechanism 52 includes an expansion mechanism 521; The expansion mechanism 521 includes a cylindrical block 5211, a support mechanism 522 is installed on the top of the cylindrical block 5211, a plurality of sliding blocks 5212 are arranged on the outer cover of the cylindrical block 5211, the sliding blocks 5212 are slidably connected with the cylindrical block 5211, a through groove 5217 is provided at the bottom of the sliding block 5212, a support block 5213 is arranged in the through groove 5217, a slide groove 5216 is provided on the side wall of the support block 5213, and a side wall of the through groove 5217 is arranged on the slide groove 5216. 16, the side wall of the through groove 5217 is slidably connected with the slide groove 5216, the support block 5213 is fixedly connected with the cylindrical block 5211, a groove 5218 is provided on one side of the sliding block 5212, a connecting block 5215 is installed at the bottom of a plurality of sliding blocks 5212, a compression spring 5214 is installed between an adjacent pair of connecting blocks 5215, a pressing rod 523 is installed on the side wall of the sliding block 5212, and an ejection mechanism 524 is installed at the bottom of the expansion mechanism 521; The ejection mechanism 524 includes a cylinder 5241 installed in the L-shaped frame 51 and a plane bearing 5242 installed on one side of the L-shaped frame 51. The bottom of the support block 5213 is fixedly connected to the top surface of the plane bearing 5242. One end of the cylinder 5241 passes through the plane bearing 5242 and is arranged in the groove 5218. One end of the cylinder 5241 is fixedly connected to a tapered block 5243. The pressing rod 523 includes a second cylinder 5231, a second groove 5232 is formed on the side wall of the second cylinder 5231, a first slide bar 5233 is sleeved in the second cylinder 5231, the second cylinder 5231 is slidably connected to the first slide bar 5233, one end of the first slide bar 5233 is hinged to a first frame 5234, a pressing block 5235 is installed in the first frame 5234, at least one second bolt 5237 is installed on the side wall of the first slide bar 5233, one end of the second bolt 5237 is arranged outside the second cylinder 5231 through the second groove 5232, and a hook 5236 is fixedly connected to the bottom of the first frame 5234; A first servo motor 4 is installed at one end of the rotating shaft 54, and the first servo motor 4 is fixedly connected to the first support rod 2. A first sleeve 21 is installed on the top of the first support rod 2, and a clamping mechanism 6 is installed in the first sleeve 21. A cutting mechanism 7 is arranged outside one side of the flipping mechanism 5.

[0022] The first servo motor 4 can drive the flip mechanism 5. When the steel drum limited by the first limiting mechanism 52 is trimming, one end of the second limiting mechanism 53 tilts downward, so that the steel drum in the second limiting mechanism 53 and the cut steel drum edge can slide out of the second limiting mechanism 53, thereby realizing unloading. After unloading, the worker re-sets the new steel drum that needs to be trimmed in the second limiting mechanism 53, and further drives the cylinder 5241 to make the conical block 5243 squeeze the groove 5218, thereby pushing the sliding block 5212 to move outward, thereby driving the pressing rod 523 to press and limit the steel drum. The first servo motor 4 can drive the flip mechanism 5, and when the steel drum limited by the first limiting mechanism 52 is trimming, one end of the second limiting mechanism 53 tilts downward, so that the steel drum in the second limiting mechanism 53 and the cut steel drum edge can slide out of the second limiting mechanism 53, so that the material can be unloaded easily. Specifically, the operator sets the steel drum 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 steel drum that is about to be fed in. When the new steel drum is placed, the cylinder 5241 starts to work, and the cylinder 5241 pushes the conical block 5243 to move along the plane bearing 5242 and enter the groove 5218 at the bottom of the sliding block 5212. The conical 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 pressure rod 523 installed on its side wall also expands outward, and the extrusion block 5235 of the pressure rod 523 tightly adheres to the inner wall of the steel drum, thereby achieving a firm fixation of the steel drum. The length of each pressure rod 523 can be adjusted separately, and it can be used with the sliding block 5212 to adapt to steel drums of different specifications, thereby improving the versatility and application range of the equipment. For non-circular steel drums (such as elliptical), the steel drum can be preliminarily positioned by pre-adjusting the length of each pressure rod 523, and then combined with the outward sliding of the sliding block 5212, it is ensured that even irregularly shaped steel drums can be firmly clamped, ensuring the accuracy of the trimming operation. Since the length of the compression rod 523 can be adjusted individually, the operator can make fine adjustments according to the shape and size of the specific steel barrel, ensuring that the steel barrel can be fixed with the most appropriate force and position every time, thereby improving the processing accuracy. Further, the first servo motor 4 is started, driving the L-shaped frame 51 and the first limiting mechanism 52 and the second limiting mechanism 53 inside it to make appropriate angle 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 cutter mechanism 7 located on one side of the flip mechanism 5 is started to cut the edge of the steel barrel according to the preset path. When the steel barrel at the beginning of the second limiting mechanism 53 is trimming, the steel barrel to be trimmed can be placed on the first limiting mechanism 52. In this process, the support mechanism 522 and the clamping mechanism 6 provide stable support for the entire expansion mechanism 521 to ensure stability during the trimming process. After the trimming is completed, the first servo motor 4 rotates in the opposite direction, so that the rotating shaft 54 ​​drives one end of the L-shaped frame 51 and the second limiting mechanism 53 inside to tilt downward. The cylinder 5241 is further reset, and the contraction spring 5214 between the sliding block 5212 shrinks due to the loss of external force, helping the sliding block 5212 and the pressing rod 523 to quickly reset. Due to the effect of gravity, the steel drum with trimmed edges and its trimmed edges will naturally slide out of the second limit mechanism 53 to achieve automatic unloading. The sliding out of the steel drum prepares for the clamping of the next steel drum. The operator quickly adds a new steel drum to the second limit mechanism 53, and the entire system immediately enters the next cycle and continues the above-mentioned workflow.The hook 5236 can hold the cut edge of the steel drum to prevent the cut edge of the steel drum from falling down, thereby facilitating the unloading of the cut edge of the steel drum.

[0023] The supporting mechanism 522 includes a first cylinder 5221, in which a first screw rod 5223 is sleeved, and the first screw rod 5223 is threadedly connected to the first cylinder 5221. First grooves 5222 are provided on both sides of the first cylinder 5221. A rotating block 5226 is installed at one end of the first screw rod 5223, and a first clamping block 5228 is installed on the top of the rotating block 5226. The first clamping block 5228 is arranged in the first screw rod 5223, and the first clamping block 5228 is rotatably connected to the first screw rod 5223. First bolts 5227 are fixedly connected on both sides of the rotating block 5226, and one end of the first bolt 5227 is arranged outside the first cylinder 5221 through the first groove 5222. A first disc block 5224 is installed at one end of the first screw rod 5223, and a first rubber pad 5225 is installed on the top of the first disc block 5224. Before placing the steel drum on the second limiting mechanism 53, the operator can pre-adjust the position of the first screw rod 5223 according to the size of the steel drum to adapt to steel drums of different specifications. This can be achieved by manually rotating the first screw rod 5223 or using an electric tool to support steel drums of different specifications. By screwing the bolt into the first bolt 5227, the bolt presses the first cylinder 5221, thereby achieving the limitation of the first screw rod 5223 and preventing the first screw rod 5223 from moving up and down.

[0024] The clamping mechanism 6 includes a second sleeve 61 installed in the first sleeve 21, 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, a limiting strip 631 is installed on the first rod body 63, the second sleeve 61 is provided with a limiting groove that cooperates with the limiting strip 631, the limiting groove is clamped with the limiting strip 631, a second screw rod 68 is sleeved in the first rod body 63, the second screw rod 68 is threadedly connected to the first rod body 63, a second servo motor 62 is installed on one end of the second screw rod 68, and the second servo motor 62 is fixedly connected to the second sleeve 61.

By driving the second servo motor 62 to drive the second screw rod 68 to rotate, the first rod body 63 can be driven to rotate, thereby driving the first rod body 63 to move downward, and further making the second disc block 64 press the steel drum, and since the position of the second disc block 64 is adjustable, it can 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.

A fourth servo motor 712 is installed on the top of the second frame 710, and a rotor of the fifth servo motor 713 is fixedly connected to the cutter 711. Before the trimming operation begins, the fifth servo motor 713 is started to drive the third screw rod 714 to rotate. Since the third screw rod 714 is threadedly connected to the moving block 716, the rotational motion is converted into linear motion, so that the moving block 716 moves along the guide rail 78, and the fifth servo motor 713 continues to operate to accurately move 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 to ensure that the cutter 711 is accurately aligned with the area to be trimmed of the steel drum, and the fourth servo motor 712 is started, and its rotor directly drives the cutter 711 to rotate. The cutter 711 is rotatably connected to the second frame 710 to ensure that it can remain stable during the rotation process. The spring 79 provides a certain elastic support for the second slide bar 715 to ensure that the cutter 711 can apply pressure evenly to achieve smooth cutting. The presence of the spring 79 also allows the cutter 711 to automatically adjust when encountering slight resistance, avoiding excessive pressure causing damage to the equipment or deformation of the steel drum.

[0026] The cutter mechanism 7 includes a third cylinder 71, which is fixedly connected to the second frame 710, a second rod 72 is sleeved in the third cylinder 71, and the second rod 72 is slidably connected to the third cylinder 71.

A second stop pin 77 is sleeved in one side of the connector 74, and the second stop pin 77 is threadedly connected to the connector 74. A positioning block 611 is provided on one side of the connecting cylinder 610, and the diameter of the second disc block 64 is longer than the diameter of the connecting cylinder 610. By arranging a mold matching the steel drum to be trimmed outside the connecting tube 610, the mold will also rotate when the steel drum rotates, and then contact the mold through the second slide bar 715. The second slide bar 715 can drive the cutter 711 to move along the edge of the steel drum through the second frame 710. By arranging a mold matching the steel drum to be trimmed outside, the cutter 711 can accurately cut along the edge of the steel drum, and even non-standard round steel drums can complete the trimming operation smoothly. This greatly expands the application range of the equipment and improves production efficiency.

[0027] One end of the crossbar 75 is provided with a ball bearing 76. The ball bearing 76 rolls, thereby reducing the friction between the crossbar 75 and the mold, so that the crossbar 75 can move more smoothly.

[0028] Specifically, the working principle of the present invention is as follows: In the trimming device for packaging steel drum production, the conical block 5243 is first driven by the cylinder 5241 to enter 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 compression rod 523 installed on its side wall also expands outward, and the hook 5236 on the compression rod 523 tightly adheres to the inner wall of the steel drum to achieve a firm fixation of the steel drum. The length of each compression rod 523 can be adjusted individually, and it can be used with the sliding block 5212 to adapt to steel drums of different specifications, thereby improving the versatility and scope of application of the equipment. In addition, the support mechanism 522 and the clamping mechanism 6 provide stable support for the entire expansion mechanism 521, ensuring the stability of the steel drum during processing.

[0029] When the steel drum is firmly fixed, 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 angle adjustments, so that the steel drum can enter the trimming station correctly. At this time, the cutter mechanism 7 located on one side of the flip mechanism 5 is started, and the fifth servo motor 713 drives the third screw rod 714 to rotate, so that the moving block 716 moves accurately to the predetermined cutting position along the guide rail 78. The fourth servo motor 712 starts and directly drives the cutter 711 to rotate to perform the trimming operation. At the same time, the third servo motor 66 drives the connecting tube 610 to rotate through the belt 65, and then the second disc block 64 drives the steel drum to rotate synchronously, ensuring that the cutter 711 can perform continuous and smooth cutting along the edge of the steel drum, and even non-standard round steel drums can complete the trimming operation smoothly.

[0030] After the trimming is completed, the first servo motor 4 rotates in the opposite direction, so that the rotating shaft 54 ​​drives the L-shaped frame 51 and one end of the second limiting mechanism 53 inside to tilt downward, and the steel drum that has completed the trimming and the cut edge will naturally slide out of the second limiting mechanism 53 to achieve automatic unloading. The cylinder 5241 is reset, and the contraction spring 5214 between the sliding block 5212 shrinks due to the loss of external force, helping the sliding block 5212 and the pressing rod 523 to quickly reset. The operator quickly adds a new steel drum to the second limiting mechanism 53, and the entire system immediately enters the next cycle and continues the above work process, thereby realizing an efficient and continuous steel drum trimming production process.

[0031] In summary, the present invention solves the problem that the conventional existing steel drum trimming device needs to manually remove the trimmed steel drum and the cut edge after the steel drum trimming operation is completed, thus resulting in low efficiency of steel drum trimming.
