[0034] During specific use, the packaging box is first transported to the stacking and boxing position through the intermittent transmission of the first conveying unit 6, and then the packaging cans are transported to the clamping position through the second conveying unit 53 at the same time. When the two packaging cans pass through the sickle-shaped limit baffle 51, the electric telescopic rod 52 contracts and drives the sickle-shaped limit baffle 51 to move to the left to block the subsequent packaging cans. At the same time, the packaging cans on the rear side of the electric telescopic rod 52 move to the fitting limit frame 54 with the second conveying unit 53, and then reach the clamping position. Then the conveying of the second conveying unit 53 is stopped, and the stacking and boxing work of the packaging cans is started.

[0035] like Figure 1 and Figure 2 As shown, the lifting mechanism 2 includes a mounting frame 21 fixedly connected to the upper surface of the base 1 , a first electric slide 22 is slidably connected to the mounting frame 21 up and down, and a second electric slide 23 is slidably connected to the first electric slide 22 left and right.

[0038] like Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 8 As shown, the clamping mechanism 4 includes a clamping member 44 arranged on the lower side of the second pulley 343, the clamping member 44 is provided with a first clamping member 41 for clamping a packaging can, the first clamping member 41 is provided with a second clamping member 43 for maintaining the stability of the first clamping member 41, and the second clamping member 43 and the first clamping member 41 are jointly provided with four stabilizing members 42 distributed in a circular array; the clamping member 44 includes a second fixing plate 442 clamped on the second adjusting member 32, the lower surface of the second fixing plate 442 is fixedly connected to the first fixing plate 441, and a mounting shell 444 is rotatably connected at the center position of the upper surface of the first fixing plate 441, and a spline shaft 443 is fixedly connected at the center position of the mounting shell 444, and the top end of the spline shaft 443 passes through the upper surface of the second fixing plate 442 and cooperates with the bottom end spline of the second pulley 343, and the inner circumferential surface of the mounting shell 444 is fixedly connected with arc push blocks 445 at the four corners of the first fixing plate 441 corresponding to the inner circumferential surface of the mounting shell 444.

[0039] like Figure 3 , Figure 4 and Figure 6As shown, the first clamping member 41 includes a sickle-shaped clamping plate 411 slidably connected to the four corners of the upper surface of the first fixed plate 441, and two second elastic telescopic connecting seats 413 symmetrically arranged with the sickle-shaped clamping plate 411 as a reference are arranged on the horizontal section of the sickle-shaped clamping plate 411, and the second elastic telescopic connecting seat 413 is fixedly connected to the upper surface of the second fixed plate 442, and a pulling seat 414 is fixedly connected to the upper surface of the horizontal section of the sickle-shaped clamping plate 411, and an auxiliary roller is arranged on the lower surface of the pulling seat 414, and the auxiliary roller is located on the inner side of the mounting shell 444 and is slidably matched with the corresponding arc push block 445, and a curved rubber pad 412 is fixedly connected to one side of the vertical section of the first fixed plate 441 close to the center of the first fixed plate 441, and the side of the curved rubber pad 412 away from the vertical section of the sickle-shaped clamping plate 411 is an arc setting.

[0040] like Figure 3 , Figure 6 and Figure 7 As shown, the second clamping member 43 includes a connecting column 431 fixedly connected to the lower surface of the first fixed plate 441, the bottom end of the connecting column 431 is fixedly connected to a fixed disk 432, four telescopic auxiliary rods 433 are evenly distributed on the circumferential surface of the fixed disk 432, and one end of the telescopic auxiliary rod 433 away from the fixed disk 432 is fixedly connected to the vertical section of the corresponding sickle-shaped clamping plate 411.

[0041] During specific use, after the packaging can is moved to the specified position, the first electric slide 22 moves downward on the mounting frame 21, driving multiple sickle-shaped clamping plates 411 to move downward until they are mounted on the packaging can. Then the assembly part 34 drives the two mounting shells 444 to rotate on the first fixed plate 441 synchronously through the spline shaft 443. At this time, the arc surface of the arc push block 445 slides from thin to thick against the auxiliary roller on the pulling seat 414. In the process of sliding against the auxiliary roller, the arc push block 445 generates a pulling force on the pulling seat 414 toward the center of the mounting shell 444, driving the sickle-shaped clamping plates 411 to slide synchronously on the first fixed plate 441. At this time, the sickle-shaped clamping plates The vertical section of 411 gradually approaches the packaging can to clamp the packaging can. Since the side of the curved rubber pad 412 away from the vertical section of the sickle-shaped clamping plate 411 is curved, as the sickle-shaped clamping plate 411 clamps the packaging can, the curved rubber pad 412 is compressed and deformed under the pressure of the sickle-shaped clamping plate 411 and gradually covers the can body of the packaging can, thereby increasing the contact area with the can body and making the clamping more stable. During the movement of the sickle-shaped clamping plate 411, the telescopic auxiliary rod 433 on the fixed disk 432 is extended and retracted to ensure the stability of the four sickle-shaped clamping plates 411 during the movement, so as to better clamp the packaging can.

[0042] like Figure 3 , Figure 6 and Figure 7 As shown, the stabilizing member 42 includes two first elastic telescopic connecting seats 422 fixedly connected to the fixed end of the telescopic auxiliary rod 433 and symmetrical with the telescopic auxiliary rod 433 as a reference. The bottom ends of the two first elastic telescopic connecting seats 422 are commonly fixedly connected to a suction cup 423. The upper surface of the suction cup 423 is slidably connected to an adjusting rod 426. The top of the adjusting rod 426 is rotatably connected to two upper and lower symmetrical connecting rollers 425. The telescopic auxiliary rod 433 corresponds to the vertical section of the sickle-shaped clamping plate 411 fixedly connected to the vertical section of the sickle-shaped clamping plate 411. A fixed block 421 is fixedly connected, and a placement groove 424 is opened on the fixed block 421. The top end of the adjusting pull rod 426 passes through the interior of the placement groove 424. The upper and lower inner walls of the placement groove 424 are provided with protrusions, and are staggered. The protrusion on the lower side is located at the position where the protrusion on the upper side is close to the direction of the connecting column 431. The upper end of the upper connecting roller 425 slides with the lower end of the upper protrusion, and the lower end of the lower connecting roller 425 slides with the upper end of the lower protrusion. The suction cup 423 adopts the existing manual suction cup technology.

[0043] During specific use, after multiple sickle-shaped clamping plates 411 are sleeved on the packaging can, the suction cup 423 is attached to the upper surface of the packaging can, and with the elastic force of the first elastic telescopic connecting seat 422 itself, the suction cup 423 is pressed against the upper surface of the packaging can. At the same time, when the sickle-shaped clamping plate 411 moves, the fixed block 421 is also pushed to move synchronously. At this time, the protrusion on the upper inner wall of the placement groove 424 slides against the upper side of the connecting roller 425 above, and generates a downward thrust on the connecting roller 425. The connecting roller 425 pushes the adjusting pull rod 426 to exhaust the air at the bottom of the suction cup 423, so that the suction cup 423 is adsorbed on the upper surface of the packaging can, and the packaging can is clamped for the second time.

[0044] It should be noted that when the sickle-shaped clamping plate 411 releases its clamp on the packaging can, the fixed block 421 moves in the opposite direction. At this time, the protrusion on the lower inner wall of the placement groove 424 slides against the lower side of the connecting roller 425 below, generating an upward thrust on the lower connecting roller 425. At this time, the adjustment rod 426 moves upward, allowing the bottom of the suction cup 423 to re-enter the air, thereby releasing the suction of the suction cup 423 on the packaging can.

[0045] like Figure 3 , Figure 8 and Fig. 9 As shown, the alignment member 33 includes an alignment plate 333, and the fixed connecting frame 342 and the movable connecting frame 346 both slide up and down and are connected with the alignment plate 333 through the top of the alignment plate 333, and two connecting ear plates 331 symmetrical with the alignment plate 333 as a reference are fixedly connected, and the lower surface of the connecting ear plate 331 is fixedly connected with an elastic telescopic connecting rod 332, and the bottom end of the elastic telescopic connecting rod 332 is fixedly connected to the upper surface of the fixed connecting frame 342.

[0046] During specific use, after the clamping of the packaging can is completed, the first electric slide 22 moves upward, driving the packaging can to move upward to the specified position, and then the second electric slide 23 slides to the left to move the clamped packaging can to the top of the packaging box. At this time, the first electric slide 22 moves downward, and the bottom end of the alignment plate 333 contacts the edge of the packaging box. When the first electric slide 22 moves downward, the alignment plates 333 in multiple positions correspond to the four corners of the packaging box respectively. At this time, when the alignment plate 333 moves downward, the packaging box can be preliminarily positioned, and the first electric slide 22 continues to move downward. After the alignment plate 333 contacts the upper surface of the first conveying unit 6, the alignment plate 333 slides upward on the assembly part 34, so that the packaging can can continue to move downward to the stacking and boxing position, and then the clamping of the packaging can is released, and the packaging can is placed inside the packaging box to complete the stacking and boxing of the packaging can.

[0047] After completing the stacking and packing of the packaging cans, the sickle-shaped clamping plate 411 is released from the packaging cans, and then the first electric slide 22 moves upward, driving the sickle-shaped clamping plate 411 to separate from the packaging box. At this time, the second electric slide 23 slides to the right, and moves the sickle-shaped clamping plate 411 back to the top of the second conveying unit 53, and repeats the above steps to perform the next stacking and packing operation of the packaging cans.

[0048] like Figure 3 and Figure 8 As shown, the first adjusting member 31 includes a supporting column 312 fixedly connected to the rear side of the upper surface of the fixed connecting frame 342, the upper surface of the supporting column 312 is hinged with an articulated pull rod 311, and the front end of the upper surface of the movable connecting frame 346 is also provided with an articulated pull rod 311 and a supporting column 312, the right ends of the two articulated pull rods 311 are hinged with a connecting plate 315 together, and a limiting slide rod 313 passes through the connecting plate 315 from left to right and is slidably connected, and there is a clearance fit between the connecting plate 315 and the limiting slide rod 313, and the left end of the limiting slide rod 313 is fixedly connected with a connecting slide seat 314, and the lower surface of the connecting plate 315 is rotatably connected with a first pulley 316, and the first pulley 316 is arranged on the right side of the two second pulleys 343, and the two second pulleys 343 and the first pulley 316 are connected by a synchronous belt transmission.

[0049] like Figure 3 , Figure 8 and Fig. 9As shown, the second adjusting member 32 includes two left-right symmetrical mounting cross bars 322 fixedly connected to the inner wall of the rear side of the fixed connecting frame 342, the front end of the mounting cross bars 322 passes through the front side of the movable connecting frame 346, and is slidably connected to the movable connecting frame 346, and three groups of left-right mounting pin holes 323 are opened on the mounting cross bars 322, the number of each group of mounting pin holes 323 is two, and they are symmetrically arranged front to back, and each group of mounting cross bars 322 corresponds to the clamping position of a packaging can, and the upper surface of the left mounting cross bar 322 is fixedly connected to the round rod slide 324, the connecting slide 314 is slidably connected to the round rod slide 324 front and back, and the connecting slide 314 and the round rod slide 324 are clearance fit, and the bottom end of the connecting slide 314 is provided with a roller, so that there is rolling friction between it and the upper surface of the mounting cross bar 322 at its bottom.

[0050] When the number of packaging cans clamped at one time needs to be changed, the first electric slide 22 and the second electric slide 23 cooperate to drive the movable connecting frame 346 to move upward to the highest point on the right side of the mounting frame 21, first remove the fastening bolts between the second fixing plate 442 and the mounting cross bar 322 on the movable connecting frame 346, and then extend the electric push rod 321 to push the movable connecting frame 346 to move forward, and at the same time, slide the door-shaped mounting frame 345 on it forward on the second electric slide 23 to ensure that the movable connecting frame 346 is stable during movement, until the electric push rod 321 is fully extended, at this time, the movable connecting frame 346 drives the second fixing plate 442 thereon to move to the position of a group of mounting pin holes 323 at the front end of the mounting cross bar 322, and fix the second fixing plate 442 on the movable connecting frame 346 on the mounting cross bar 322 by the fastening bolts again. 2 remains stationary, and the second fixed plate 442 on the fixed connecting frame 342 also remains stationary. When the electric push rod 321 extends and pushes the movable connecting frame 346 to move, the second fixed plate 442 on the movable connecting frame 346 pulls the synchronous belt through the second pulley 343 thereon, and generates a pulling force to the left on the first pulley 316. The first pulley 316 is forced to drive the connecting piece 315 to slide on the limiting slide bar 313, and the limiting slide bar 313 drives the connecting slide seat 314 to slide forward synchronously on the round rod slide seat 324. When the electric push rod 321 completes the extension, the first pulley 316 also moves between the front and rear two second pulleys 343 and is in the same straight line with the two second pulleys 343, and cooperates with the setting of the tensioning wheel group 344 to apply thrust to the synchronous belt, so that the two second pulleys 343 and the first pulley 316 are synchronously transmitted, and the mounting pin holes 323 of the middle position group are vacant. Fig. 9As shown in the figure, the staff then takes a new set of clamping mechanisms 4 for installation, and clamps the first elastic telescopic connecting seat 422 on the new clamping mechanism 4 on a group of mounting pin holes 323 in the middle position of the mounting cross bar 322 and fixes them by tightening bolts. At this time, the spline shaft 443 on the newly installed clamping mechanism 4 is clamped on the mounting cross bar 322 and inserted into the inside of the first pulley 316 to cooperate with the spline of the first pulley 316. At this time, the state switching from clamping two cans at a time to clamping three cans at a time is completed.

[0051] like Figures 1 to 9 As shown, the working principle is as follows: when the packaging cans are palletized and boxed, the packaging boxes are intermittently transported by the first conveying unit 6, and the packaging cans are transported to the bottom of the adjustment mechanism 3 by the second conveying unit 53. After the two cans are transported to the bottom of the adjustment mechanism 3, the subsequent packaging cans are limited by the electric telescopic rod 52, and then the first electric slide 22 moves downward to drive the sickle-shaped clamping plate 411 to approach the packaging can and sleeve it on the packaging can. At this time, the assembly part 34 drives the sickle-shaped clamping plate 411 to tighten and clamp the packaging can, and at the same time, the upper surface of the packaging can is adsorbed by the suction cup 423. After clamping, the first electric slide 22 moves upward. After moving to the specified position, the second electric slide 23 slides to the left to drive the clamped packaging cans to the top of the packaging box, and then the first electric slide 22 moves downward, and the packaging box is limited by the positioning member 33. Then, as the first electric slide 22 continues to move downward, after the packaging cans are stacked in the packaging box, the sickle-shaped clamping plate 411 releases the clamping of the packaging cans, and the first electric slide 22 moves upward, and the second electric slide 23 moves to the right to move the sickle-shaped clamping plate 411 back to the top of the second conveying unit 53. At this time, the stacking and boxing of the packaging cans is completed once, and the above steps can be repeated to carry out the next stacking and boxing of the packaging cans.
