Detailed Implementation

[0029] The present invention will be further described below with reference to the accompanying drawings:

[0030] like Figure 1-9As shown, this utility model relates to a bending and fastening device for a safety buckle on a packaging box, including a workbench 1. A transfer unit 2 is provided above the workbench 1. The transfer unit 2 is used to transfer the packaging box with the lid fastened. The transfer unit 2 includes a displacement adjustment mechanism 21 located above the workbench 1 and connected to the workbench 1 via a mounting bracket 20, and a clamping mechanism 23 located on one side of the displacement adjustment mechanism 21 and slidably connected to the displacement adjustment mechanism 21 via a first connecting plate 22. The displacement adjustment mechanism 21 is used to drive the clamping mechanism. 23 achieves spatial position transfer. The clamping mechanism 23 is used to grasp the packaging box and cooperate with the displacement adjustment mechanism 21 to transfer the packaging box. A bending and fastening unit 3 connected to the workbench 1 is provided on one side of the transfer unit 2. The bending and fastening unit 3 is used to bend and fasten the safety buckle of the packaging box. The bending and fastening unit 3 includes a first adjustment module 30 located above the workbench 1, a second adjustment module 31 located above the first adjustment module 30, and a second adjustment module 31 located above the second adjustment module 31 and connected to the second adjustment module 31 by a second connecting plate 32. The assembly consists of a slidingly connected pressing mechanism 33, a bending mechanism 34 located below the pressing mechanism 33 and connected to the second connecting plate 32, an auxiliary bending plate mechanism 35 located below the bending mechanism 34 and connected to the second connecting plate 32, a support mechanism 37 located on one side of the auxiliary bending plate mechanism 35 and connected to the auxiliary bending mechanism 35 via a first connecting block 36, and a fastening mechanism 39 located on one side of the support mechanism 37 and connected to the second connecting plate 32 via a second connecting block 38. The first adjustment module 30 is used to adjust the horizontal direction of the bending and fastening unit 3. The second adjustment module 31 is used to adjust the lateral displacement of the bending and fastening unit 3. The pressing mechanism 33 is used to limit the vertical direction of the packaging box. The bending mechanism 34 is used to bend the safety buckle of the packaging box. The auxiliary folding plate mechanism 35 is used to cooperate with the bending mechanism 34 to bend the safety buckle. The support mechanism 37 is used to cooperate with the bending mechanism 34 and the auxiliary folding plate mechanism 35 to bend the safety buckle. A limiting mechanism 4 connected to the worktable 1 is provided on both sides of the bending and fastening unit 3. The limiting mechanism 4 is used to limit the packaging box.

[0031] like Figure 1-9 As shown, further, the limiting mechanism 4 horizontally limits the packaging box, and the bending and fastening unit 3 adjusts the bending and fastening position of the packaging box on the packaging station through the first adjusting module 30 and the second adjusting module 31. The transfer unit 2 promptly transfers the packaging box with the safety buckle fastened from the packaging station to the unloading station to complete the unloading, so that the packaging work is automatically cyclical. Through the efficient collaborative work of the transfer unit 2, the bending and fastening unit 3 and the limiting mechanism 4, the packaging efficiency is improved by more than 70%.

[0032] like Figure 1-3As shown, the displacement adjustment mechanism 21 includes a horizontal drive module 210 located above the mounting frame 20 and a lifting drive module 212 slidably connected to one side of the horizontal drive module 210 via a third connecting plate 211. The horizontal drive module 210 assists the clamping mechanism 23 in the horizontal transfer of the packaging box from the packaging station to the unloading station. The lifting drive module 212 assists the clamping mechanism 23 in the lifting transfer of the packaging box. The horizontal drive module 210 drives the clamping mechanism 23 to operate precisely between the packaging station and the unloading station. Through the precise cooperation between the horizontal drive module 210 and the lifting drive module 212, the packaging box is accurately transferred in space. The displacement adjustment mechanism 21 timely and accurately changes the spatial displacement of the clamping mechanism 23, effectively ensuring the smooth unloading of the packaging box. The displacement adjustment mechanism 21 makes the cyclic packaging work run smoothly.

[0033] like Figure 1-3 As shown, the clamping mechanism 23 includes a connecting frame 231 slidably connected to one side of the lifting drive module 212 via a fourth connecting plate 230, a first clamping cylinder 232 at one end of the connecting frame 231, a first clamping part 233 at the output end of the first clamping cylinder 232, a second clamping cylinder 234 slidably connected to the slider 6 via a guide rail 5 at the other end of the connecting frame 231, and a second clamping part 235 at the output end of the second clamping cylinder 234. The first clamping cylinder 232 is used to cooperate with the second clamping cylinder 234. The first clamping part 233 and the second clamping part 235 are driven together to grip the packaging box. The second clamping cylinder 234 and the connecting frame 231 are limited by a limiting plate 236. The distance between the first clamping cylinder 232 and the second clamping cylinder 234 is adjusted by the sliding cooperation of the guide rail 5 and the slider 6 to match the size of the packaging box for easy gripping. When the second clamping cylinder 234 is adjusted to the correct position, the clamping mechanism 23 achieves precise gripping of the packaging box in cooperation with the horizontal drive module 210 and the lifting drive module 212.

[0034] like Figure 3 As shown, further, the first clamping part 233 is extended by the output end of the first clamping cylinder 232, and at the same time, the second clamping part 235 is extended by the output end of the second clamping cylinder 234. Then, the clamping mechanism 23 is moved downward to above the packaging station by the lifting drive module 212. Then, the first clamping part 233 is retracted by the output end of the first clamping cylinder 232, and at the same time, the second clamping part 235 is retracted by the output end of the second clamping cylinder 234. The second clamping part 233 and the second clamping part 235 cooperate to clamp the packaging box.

[0035] like Figure 6As shown, the first adjustment module 30 includes a first mounting base 300 disposed above the worktable, a first motor 301 disposed above the first mounting base 300, and a first coupling 302 disposed at the output end of the first motor 301. The second adjustment module 31 includes a second mounting base 310 disposed above the first coupling 302 and slidably connected to the first mounting base 300 via two guide rails 5 and a slider 6, a second motor 311 disposed above the second mounting base 310, and a second coupling 312 disposed at the output end of the second motor 311. The horizontal displacement adjustment directions of the first adjustment module 30 and the second adjustment module 31 are perpendicular to each other. The second adjustment module 31 is slidably connected to the second connecting plate 32 via two guide rails 5 and a slider 6. The displacement adjustment direction of 0 is consistent with the driving direction of the horizontal drive module 210. The first motor 301 drives the first coupling 302 to move along the output end, which in turn drives the second adjustment module 31 to move. The second adjustment module 31 drives the second coupling 312 to move along the output end through the second motor 311, which in turn drives the second connecting plate 32 to move. This causes the pressing mechanism 33, bending mechanism 34, auxiliary bending plate mechanism 35, support mechanism 37 and fastening mechanism 39 installed on the second connecting plate 32 to move synchronously. Through the coordinated displacement adjustment of the first adjustment module 30 and the second adjustment module 31, the working position of the bending and fastening unit 3 is automatically matched with the packaging box of the packaging station, so that each mechanism can smoothly bend and fasten the safety buckle of the packaging box.

[0036] like Figure 3-6 As shown, the pressing mechanism 33 includes a first support frame 330 located above the second connecting plate 32, a pressing cylinder 331 located on one side of the first support frame 330, and a pressing block 332 located at the output end of the pressing cylinder 331. The pressing cylinder 331 is used to drive the pressing block 332 to press against the box lid. The pressing mechanism 33 drives the pressing block 332 to extend and press against the box lid through the pressing cylinder 331. The pressing mechanism 33 keeps the box stable during the bending and fastening process of the safety buckle.

[0037] like Figure 3-6 As shown, the bending mechanism 34 includes a second support frame 340 fixedly connected to the second connecting plate 32 on one side of the first support frame 330, a bending cylinder 341 at one end of the second support frame 340, and a bending block 342 at the output end of the bending cylinder 341. The bending cylinder 341 is used to drive the bending block 342 to bend the safety buckle of the packaging box. The bending mechanism 34 drives the bending block 342 to extend towards the safety buckle through the bending cylinder 341, pushing the safety buckle to be vertically aligned with the side of the packaging box. Here, the alignment action is achieved by the following auxiliary bending plate mechanism 35 cooperating synchronously with the support mechanism 37.

[0038] like Figure 3 , 8As shown, the auxiliary folding mechanism 35 includes a third support frame 350 disposed above the second connecting plate 32, a first cylinder 351 disposed above the third support frame 350, a second cylinder 352 disposed at the output end of the first cylinder 351, a connecting portion 353 disposed at the output end of the second cylinder 352, and a folding shaft 354 disposed at one end of the connecting portion 353. The first cylinder 351 is used to drive the folding shaft 354 to insert into the safety buckle of the packaging box, and the second cylinder 352 is used to drive the folding shaft 354 to pull down and cause the safety buckle of the packaging box to bend. The auxiliary folding mechanism 35 first passes through the first cylinder The output end of cylinder 351 extends outward, driving the second cylinder 352 to move outward. As the output end of the second cylinder 352 extends upward, the folding shaft 354, which is perpendicularly connected to the connecting part 353, moves upward synchronously. At this time, the folding shaft 354 can avoid the safety buckle. When the folding shaft 354 extends higher than the safety buckle, the output end of the first cylinder 351 retracts, driving the second cylinder 352 to move back, causing the folding shaft 354 to extend above the safety buckle. Then, the output end of the second cylinder 352 retracts, causing the folding shaft 354 to move downward synchronously. At the same time, the folding shaft 354 squeezes the safety buckle, causing it to bend at a certain angle.

[0039] like Figure 8 As shown, the support mechanism 37 includes a support cylinder 371 fixedly connected to the third support frame 350 via a first connecting block 36 on one side of the third support frame 350, and a support block 372 located at the output end of the support cylinder 371. The support cylinder 371 is used to drive the support block 372 to extend and cooperate with the auxiliary folding plate mechanism 35 and the bending mechanism 34 to bend the safety buckle. The support mechanism 37 extends upward through the output end of the support cylinder 371, driving the support block 372 to move upward synchronously, limiting the front end of the packaging box safety buckle, and ensuring that the auxiliary folding plate mechanism can bend the safety buckle at a certain angle.

[0040] like Figure 4-8 As shown, the fastening mechanism 39 includes a fastening cylinder 391 fixedly connected to the second connecting plate 32 via a second connecting block 38 on one side of the support mechanism 37, and a fastening block 392 located at the output end of the fastening cylinder 391. The fastening cylinder 391 is used to drive the fastening block 392 to extend and push the safety buckle into the packaging box body to complete the fastening. The fastening mechanism 39 extends upward through the output end of the fastening cylinder 391. After the action of aligning the safety buckle with the side of the packaging box is completed by the bending mechanism 34, the auxiliary bending plate mechanism 35 and the support mechanism 37, the fastening block 392 pushes the safety buckle into the packaging box.

[0041] like Figure 1 , 4As shown, the limiting mechanism 4 includes a fourth support frame 40 located above the workbench 1, a limiting cylinder 41 located above the fourth support frame 40, and a limiting block 42 located at the output end of the limiting cylinder 41. The limiting cylinder 41 is used to drive the limiting block 42 to extend and horizontally limit the packaging box. The limiting mechanism 4 drives the limiting block 42 to horizontally limit the packaging box through the limiting cylinder 41, and works synchronously with the pressing mechanism 33 to ensure that the packaging box is in a stable state during the bending and fastening process, and avoids errors in the fastening of the safety buckle.

[0042] Working principle: After the equipment is started, the limiting mechanism 4 starts working first. The limiting cylinder 41 on the fourth support frame 40 above the workbench 1 drives the limiting block 42 to extend, horizontally limiting the packaging box located at the packaging station to ensure its accurate positioning. The first adjustment module 30 and the second adjustment module 31 of the bending and fastening unit 3 start working. The first motor 301 on the first mounting base 300 drives the first coupling 302 to move, causing the second adjustment module 31 to move horizontally. The second motor 311 on the second mounting base 310 drives the second coupling 312 to move, causing the second connecting plate 32 and the pressing mechanism 33, bending mechanism 34, auxiliary bending plate mechanism 35, support mechanism 37, and fastening mechanism 39 mounted on it to move laterally. Through the coordinated adjustment of the two adjustment modules, the working position of the bending and fastening unit 3 is precisely matched with the safety buckle position of the packaging box. Next, the pressing mechanism 33 starts to move, through the first support,The clamping cylinder 331 on 330 drives the clamping block 332 to extend downwards, tightly fitting the box lid surface and vertically limiting and fixing the box to ensure stability in subsequent operations. Then, the support mechanism 37 and the auxiliary folding mechanism 35 start synchronously. At the same time, the first cylinder 351 of the auxiliary folding mechanism 35 drives the second cylinder 352 to move outwards, causing the folding shaft 354 to extend upwards to avoid the safety buckle. At this time, the support cylinder 371 of the support mechanism 37 drives the support block 372 to extend upwards, limiting the front end of the safety buckle to ensure the accuracy of the bending angle. When the folding shaft 354 is higher than the safety buckle, the second cylinder 352 retracts, causing the folding shaft 354 to move downwards, squeezing the safety buckle and bending it at a certain angle. The bending cylinder 341 on the second support frame 340 of the bending mechanism 34 drives the bending block 342 to extend towards the safety buckle, aligning the safety buckle with the side of the packaging box. Then, the fastening mechanism 39 begins operation, with the fastening cylinder 39 driving the fastening block 392 to extend. After the bending mechanism 34, auxiliary bending plate mechanism 35, and support mechanism 37 work together to align the safety buckle with the side of the packaging box, the fastening block 392 pushes the safety buckle upwards, precisely inserting it into the packaging box body, completing the fastening action. After fastening, the pressing block 332 of the pressing mechanism 33 retracts to release the packaging box. Simultaneously, the limiting block 42 of the limiting mechanism 4 retracts, and the bending and fastening unit 3, through the first adjusting module 30 and the second adjusting module 3... 1. Reset to the initial position, the displacement adjustment mechanism 21 of the transfer unit 2, through the coordinated operation of the horizontal drive module 210 and the lifting drive module 212, moves the clamping mechanism 23 above the packaging box. The first clamping cylinder 232 and the second clamping cylinder 234 of the clamping mechanism 23 adjust the distance through the guide rail 5 and the slider 6, so that the first clamping part 233 and the second clamping part 235 are accurately aligned with the two sides of the packaging box. Then, the output end of the first clamping cylinder 234 drives the first clamping part 233 to extend, and at the same time, the output end of the second clamping cylinder 234 drives the second clamping part 235 to extend. The lifting drive module 212 moves the clamping mechanism 23 downward to above the packaging box station, and then the first clamping cylinder... The output end of cylinder 232 drives the first clamping part 233 to retract, and simultaneously, the output end of the second clamping cylinder 234 drives the second clamping part 235 to retract. The first clamping part 233 and the second clamping part 235 cooperate to grip the packaging box. Next, the lifting drive module 212 causes the clamping mechanism 23 to move upward, so that the clamping mechanism 23 grips the completed fastening packaging box and removes it from the packaging station. The horizontal drive module 210 then transfers it to the unloading station and releases the packaging box. This process is repeated to achieve automated cyclic packaging production. Through the efficient coordination of the limiting mechanism, bending and fastening unit, and transfer unit, the packaging efficiency is increased by more than 70% compared to traditional manual packaging, while ensuring the accuracy of the safety buckle bending and fastening and the continuity of production.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model. Therefore, without departing from the design spirit of the present utility model, any equivalent changes or modifications made by those skilled in the art to the structure, features and principles of the present utility model should fall within the protection scope of the patent application of the present utility model.
