[0039] To make the technical means, creative features, and achieved objectives and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0040] Example: Figure 1 As shown, a cam mechanism includes two sets of heavy-duty connectors 1. The mechanism can be installed on the side of a transfer device through the two sets of heavy-duty connectors 1. A hanging plate group 11 is fixedly installed on the side of the two sets of heavy-duty connectors 1. The hanging plate group 11 is composed of multiple rectangular plates. A feeding assembly 2 for stably conveying packing straps is installed on the side of the heavy-duty connectors 1. A mechanism assembly 3 for completing automated strapping operation through multiple actions is installed on the side of the heavy-duty connectors 1 corresponding to the feeding assembly 2.

[0041] The feeding component 2 can stably feed the packing strap while simultaneously detecting it, and can also stably clamp it when not feeding.

[0042] like Figures 2 to 5 As shown, the belt feeding assembly 2 includes a belt guide plate 21 inclinedly disposed on the side of the hanging plate assembly 11. The belt guide plate 21 is a rectangular plate. A connecting plate 22 is fixedly installed on the side of the hanging plate assembly 11 corresponding to the position of the belt guide plate 21, and the belt guide plate 21 is also attached to the side of the connecting plate 22. A first gear 23 is disposed on the side of the connecting plate 22. The first gear 23 is a spherical gear with a round wheel on its side. A first motor 231 is fixedly disposed on the side of the connecting plate 22 away from the first gear 23, and the output end of the first motor 231 is fixedly connected through and fixed to the side of the first gear 23. A second gear 24 is rotatably mounted on the side of the connecting plate 22, corresponding to the position of the first gear 23, and meshes with the first gear 23. The second gear 24 is a circular gear with a round wheel on its side. A first guide wheel 241 is rotatably mounted through the side of the guide plate 21 and is synchronously driven with the second gear 24 via a synchronous belt. In addition, a feeding wheel 25 is mounted on the side of the connecting plate 22, corresponding to the position of the first gear 23. The feeding wheel 25 is a round wheel. A second motor 251 is fixedly mounted on the side of the connecting plate 22 away from the feeding wheel 25. The output end of motor 251 is fixedly connected to the side of the feeding wheel 25. A second guide wheel 26 is rotatably mounted on the side of the connecting plate 22 corresponding to the position of the feeding wheel 25. A first detection frame 27 is provided on the side of the guide plate 21. The first detection frame 27 is composed of rollers, brackets, and springs, and can be elastically supported by the brackets while adhering to the side of the strapping tape by the rollers. Specifically, the strapping tape is conveyed from the external device and passes between the first gear 23 and the second gear 24, and between the feeding wheel 25 and the second guide wheel 26, and is positioned against the side of the guide plate 21. The first motor 231 drives the first gear 23 to rotate, and the first gear 23 meshes with the second gear 24 to make the wheel convey the packing strap. In addition, the first guide wheel 241 rotates synchronously with the second gear 24 to convey the packing strap. Simultaneously, the second motor 251 drives the feeding wheel 25 to rotate, which can further stabilize the conveying of the packing strap. The second guide wheel 26 passively rotates to constrain the packing strap. When the packing strap is not being conveyed, the first detection frame 27 performs elastic constraint and compression on the packing strap to stabilize its position.

[0043] The mechanism component 3 enables automated multi-step tape application, and its simple structure reduces costs.

[0044] like Figures 2 to 7As shown, the mechanism assembly 3 includes a base frame 31 fixedly mounted on the side of the hanging plate assembly 11. The base frame 31 is an "H"-shaped frame composed of multiple rectangular plates. A third motor 32 is fixedly mounted on the side of the hanging plate assembly 11. The third motor 32 works with a reduction gearbox to increase torque. A linkage shaft 321 is fixedly connected to the output end of the third motor 32, and the linkage shaft 321 passes through the base frame 31 and is rotatably mounted thereto. The linkage shaft 321 is a cylindrical rod with four sets of annular grooves equidistantly opened on its side. A first cam 33, a second cam 34, a third cam 35, a fourth cam 36, and a fifth cam 37 are equidistantly sleeved on the side of the linkage shaft 321. The first cam 33, the second cam 34, the third cam 35, the fourth cam 36, and the fifth cam 37 are cam blocks of different shapes and are set at different angles as required. A mating wheel 38 is fixedly sleeved on the side of shaft 321 away from the third motor 32. The mating wheel 38 is a circular block with a protrusion on the side. A second detection frame 381 is set on the side of the hanging plate assembly 11 corresponding to the position of the mating wheel 38. The second detection frame 381 is composed of a linkage structure and a photoelectric sensor. Specifically, the third motor 32 can drive the first cam 33, the second cam 34, the third cam 35, the fourth cam 36, the fifth cam 37 and the mating wheel 38 to rotate synchronously. When the mating wheel 38 rotates one revolution, it can trigger the linkage of the second detection frame 381 to move. The photoelectric sensor detects and feeds back to the external controller, knowing that the mating wheel 38 has rotated one revolution. Synchronously, the mating wheel 38 actively squeezes the first detection frame 27, so that the support is squeezed by the compression roller to press the packing strap.

[0045] The base frame 31 has a right pressure post 331, a synchronization post 351, and a left pressure post 371 slidably mounted on its side. The right pressure post 331, synchronization post 351, and left pressure post 371 are respectively attached to the lower sides of the first cam 33, the third cam 35, and the fifth cam 37. The right pressure post 331, synchronization post 351, and left pressure post 371 are elastically pulled by external springs to ensure they always remain attached to the sides of the first cam 33, the third cam 35, and the fifth cam 37. The main body consists of rollers and rectangular rods, with cutting blades and other cooperating components on its lower side. A feeding frame 341 and a merging frame 361 are rotatably mounted on the side of the base frame 31, respectively abutting the second cam 34 and the fourth cam 36. The feeding frame 341 and the merging frame 361 are rotating linkage structures with corresponding cooperating components on their sides. An auxiliary frame 39 is slidably mounted on the bottom side of the base frame 31, corresponding to the lower side of the synchronization frame 351. The auxiliary frame 39 is a rectangular frame with elastically mounted friction rods. A fourth motor 391 is fixedly installed, and the output end of the fourth motor 391 is rotatably connected to the auxiliary frame 39 via a cam linkage structure. Specifically, when the linkage shaft 321 is rotated by the third motor 32, the first cam 33, the second cam 34, the third cam 35, the fourth cam 36, and the fifth cam 37 rotate synchronously. The sequence is as follows: first, the first cam 33 triggers the right pressure knife holder 331 to perform the right-side pressing and fixing operation of the packing strap; then, the fourth cam 36 triggers the overlapping frame 361 to complete the overlapping operation of the packing strap path; and then the fifth cam 37 triggers... The left pressure knife holder 371 performs the operation of pressing and fixing the packing strap on the left side. Then, the third cam 35 triggers the synchronous frame 351 to cut the packing strap with a cutter. At the same time, the synchronous frame 351 presses down on the friction rod of the auxiliary frame 39 to heat and weld the packing strap. The fourth motor 391 can rotate to trigger the auxiliary frame 39 to slide and adjust its position, so that the friction rod can accurately fit with the overlapping position of the packing strap for heating. Finally, the second cam 34 can trigger the tape feeding frame 341 to feed the welded and fixed packing strap, completing a series of automated tape feeding operations.

[0046] like Figure 8 As shown, an auxiliary component 4 is provided inside the linkage shaft 321. The auxiliary component 4 can fine-tune the position of each cam in real time to ensure the continuous accuracy of the automated packaging operation.

[0047] like Figures 8 to 13As shown, the auxiliary component 4 includes an inner cavity 41 formed inside the linkage shaft 321. The inner cavity 41 is a cylindrical cavity with an I-shaped cross-section. A power supply block 42 is fixedly disposed inside the inner cavity 41 near the mating wheel 38. The power supply block 42 is a rechargeable battery block. A charging port 421 is fixedly disposed on the side of the power supply block 42 and passes through the linkage shaft 321 and is flush with its side. The power supply block 42 can be directly charged through the charging port 421. An electric push rod 422 is fixedly disposed inside the inner cavity 41 at the position corresponding to the power supply block 42, and the electric push rod 422 is electrically connected to the power supply block 42 through contacts. 2 is an electric push rod with a hollowed-out side on the telescopic rod. A fifth motor 43 is fixedly installed inside the inner cavity 41, away from the mating wheel 38. The fifth motor 43 is a micro motor. A connecting rod 431 is fixedly installed at the output end of the fifth motor 43 and is movably installed inside the hollowed-out telescopic rod of the electric push rod 422. The connecting rod 431 is a spline-shaped round rod. On the wall surface of the inner cavity 41, corresponding to the positions of the first cam 33, the second cam 34, the third cam 35, the fourth cam 36, and the fifth cam 37, there are connecting grooves 44 that penetrate the linkage shaft 321 in a staggered circular array. The connecting grooves 44 are fan-shaped grooves and are six-part circular. A connecting block 45 is movably disposed within the connecting groove 44, and is fixedly connected to the inner sides of the first cam 33, the second cam 34, the third cam 35, the fourth cam 36, and the fifth cam 37. The connecting block 45 extends partially into the inner cavity 41. The connecting block 45 is a fan-shaped block. A through-hole movable cavity 451 is formed on the side of the connecting block 45 away from the fifth motor 43. The movable cavity 451 is a C-shaped groove. A retaining block 452 is movably installed inside the movable cavity 451 and fits against the wall of the connecting groove 44. The retaining block 452 is a fan-shaped block made of wear-resistant rubber. A support cylinder 453 is fixedly connected at equal intervals between the side of the locking block 452 and the wall of the movable cavity 451. The support cylinder 453 is a corrugated cylinder made of elastic material. A trigger rod 454 is fixedly installed on the lower side of the locking block 452, and part of the trigger rod 454 extends out of the interior of the movable cavity 451. A movable block 46 is rotatably set at the output end of the electric push rod 422 through a rotating block, and the movable block 46 is splined and sleeved on the side of the connecting rod 431. A mating block 47 is fixedly installed on the side of the movable block 46. The mating block 47 is a rectangular block. A mating groove 471 is opened on the side of the mating block 47 corresponding to the position of the trigger rod 454. The mating groove 471 is a rectangular groove.Specifically, the electric push rod 422 is powered by the power supply block 42, which pushes and pulls the movable block 46 to move its position. Simultaneously, the fifth motor 43 drives the connecting rod 431 to rotate, causing the movable block 46 to rotate accordingly. When the movable block 46 rotates the mating block 47 to a six-point circle position, it corresponds to any one set of connecting blocks 45 or intersects with all five sets of connecting blocks 45. The electric push rod 422 pushes the mating block 47 to engage the corresponding trigger rod 454 inside the mating groove 471. Then, the mating block 47 pushes the trigger rod 454, causing the locking block 452 to deform and slide into the movable cavity 451, thus disengaging the corresponding locking block 452 from the wall of the connecting groove 44. Subsequently, the movable block 46 drives the mating block 47 to rotate, causing the connecting block 45 to rotate and engage the corresponding position of the connecting block 45. The positions of components 33, 34, 35, 36, or 37 are fine-tuned by rotating them on the side of the linkage shaft 321. Then, the reset block 452, with the elastic support spring of the support cylinder 453 rubbing against the wall of the connecting groove 44, constrains and fixes the first cam 33, second cam 34, third cam 35, fourth cam 36, and fifth cam 37. Thus, rotation of the linkage shaft 321 triggers the corresponding components using the first cam 33, second cam 34, third cam 35, fourth cam 36, and fifth cam 37. Feedback from an external detection device ensures that the timing of each component triggering other components is accurate by individually fine-tuning the positions of the first cam 33, second cam 34, third cam 35, fourth cam 36, and fifth cam 37.

[0048] Working principle:

[0049] Preparation before strapping: The strapping is set from the external device between the second gear 24 and the first gear 23 and between the feeding wheel 25 and the second guide wheel 26. At the same time, the strapping is also attached to the side of the guide plate 21 and in contact with the first guide wheel 241. In the default state, the roller of the first detection frame 27 is always attached to and presses the strapping under the elastic action of the support spring, which plays a restraining role.

[0050] During strapping: First step, the strapping is conveyed. The first motor 231 drives the first gear 23 to rotate, and the first gear 23 and the second gear 24 mesh and rotate synchronously. The first guide wheel 241 and the second gear 24 rotate synchronously. The strapping is conveyed by the interaction of the first gear 23 and the second gear 24. The second guide wheel 26 assists in the conveying. At the same time, the second motor 251 drives the feeding wheel 25 to rotate, so that the strapping is further conveyed by the interaction of the feeding wheel 25 and the second guide wheel 26, ensuring that the strapping is stably conveyed to the base frame 31.

[0051] The second step is the strapping operation. After the material is strapped together, the third motor 32 drives the linkage shaft 321 to rotate one revolution. The corresponding first cam 33, second cam 34, third cam 35, fourth cam 36, fifth cam 37 and mating wheel 38 are triggered step by step to complete the automated strapping operation. The triggering order of each component is as follows: first cam 33, fourth cam 36, fifth cam 37, third cam 35, second cam 34 and mating wheel 38.

[0052] The first cam 33 triggers the right pressure knife holder 331 to press and fix the packing strap on the right side. The fourth cam 36 triggers the overlapping frame 361 to make the packing strap overlap. The fifth cam 37 triggers the left pressure knife holder 371 to press and fix the left side. The third cam 35 triggers the synchronization frame 351 to cut the packing strap with the cutter and simultaneously press, heat and weld the friction rod of the auxiliary frame 39 to fix the packing strap. The second cam 34 triggers the tape ejection frame 341 to eject the welded and fixed packing strap. Finally, the cooperating wheel 38 rotates one revolution to trigger the second detection frame 381, and after photoelectric detection feedback, the external controller completes one revolution. The synchronous cooperating wheel 38 actively squeezes the first detection frame 27, so that the support is squeezed by the compression roller to press the packing strap.

[0053] The third step involves real-time adjustment. When the first cam 33, second cam 34, third cam 35, fourth cam 36, and fifth cam 37 are driven to trigger each component, the continuity of the belt-driving action is detected by an external detection device. When a problem occurs with the continuity of a corresponding component, the fifth motor 43 drives the connecting rod 431 to rotate, causing the movable block 46 to rotate to the side position of the connecting block 45 of the corresponding component. The electric push rod 422 pushes the movable block 46, causing the corresponding trigger rod 454 to engage inside the mating groove 471. The trigger rod 454 is pressed, causing the locking block 452 to disengage from the wall of the connecting groove 44. Subsequently, the movable block 46 drives the connecting block 45 to make a fine adjustment of its position, so that the first cam 33, second cam 34, third cam 35, fourth cam 36, and fifth cam 37 can rotate and make a fine adjustment of their positions on the side of the linkage shaft 321.
