Description

Technical Field

[0001] The utility model relates to the technical field of cartoning machines, and particularly relates to an unpacking mechanism of a cartoning machine. Background Art

[0002] In the prior art, the unpacking mechanism of a cartoning machine requires two actions when unpacking. One is to take out the paper box in the storage box bin, and the other is to open the paper box. However, this mechanical structure usually adopts single-side support, with a relatively heavy overall weight, and it is also necessary to hold the paper box, resulting in the manipulator being prone to shaking and deformation. Summary of the Invention

[0003] The purpose of the utility model: In order to overcome the defects of the prior art, the utility model provides an unpacking mechanism of a cartoning machine, which is supported by a support rod horizontally arranged between two support plates, with better stability. The support rod has a first rod body that can rotate relative to each other and a second rod body sleeved on the first rod body. The actions of taking the box and opening the box can be realized by the relative rotation of the first rod body and the second rod body, with stronger practicability.

[0004] The utility model discloses an unpacking mechanism of a cartoning machine, including a frame. A storage box bin for storing paper boxes is arranged on the frame. It is characterized in that: there are also oppositely arranged support plate I and support plate II. A support rod is arranged between support plate I and support plate II. The support rod includes a first rod body and a second rod body arranged separately. A driving part I for driving the first rod body to rotate and a driving part II for driving the second rod body to rotate are arranged on the frame. The first rod body is rotatably arranged on support plate I, and the second rod body is rotatably arranged on support plate II and sleeved on the first rod body. A first swing arm that rotates synchronously with the second rod body is arranged on the second rod body. A support plate is hinged on the first swing arm. A first suction nozzle is arranged on the support plate. A second swing arm that rotates synchronously with the first rod body is arranged on the first rod body. A first connecting rod is hinged on the second swing arm. The other end of the first connecting rod is hinged on the support plate. At least one of support plate I and support plate II is rotatably provided with a third swing arm. A second suction nozzle that swings synchronously with the third swing arm is arranged on the third swing arm. A swing block extending backward is arranged on the first swing arm. A mounting bracket is arranged on the swing block. A second connecting rod is hinged on the mounting bracket. The other end of the second connecting rod is hinged on the third swing arm. The second suction nozzle is located at the side rear of the first suction nozzle. When the first swing arm swings, the swing block can drive the second connecting rod to move in series, so that the second suction nozzle rotates and adsorbs on the side of the paper box.

[0005] With the above technical solution, during use, the driving member II drives the second rod body to rotate, which can rotate the first suction nozzle to the storage box bin, thereby adsorbing the bottom of the paper box. At this time, the driving member II drives the second rod body to turn over, and the paper box can be taken out. At the same time, the swing block will drive the mounting rack to swing, so that the second connecting rod pushes the third swing arm to rotate, and the second suction nozzle moves to adsorb on the side of the paper box. At this time, the driving member I drives the first rod body to rotate, so that the second swing arm drives the first connecting rod to work, so that the support plate rotates relatively. Since the second suction nozzle does not move, the paper box can be opened when the first suction nozzle moves relatively. With the assistance of the second suction nozzle, the opened paper box can be prevented from closing, which is convenient for later packing and feeding. And it is supported by the support rod horizontally arranged between the support plate I and the support plate II, and its stability is relatively good. And the support rod has a first rod body that can rotate relative to each other and a second rod body sleeved on the first rod body. The actions of taking the box and opening the box can be realized by the relative rotation of the first rod body and the second rod body, and the practicability is stronger.

[0006] A further setting of the present utility model: when the support plate rotates to the support state, a support surface for supporting the support plate is further provided on the first swing arm.

[0007] With the above technical solution, the support plate can be held, thereby preventing all the forces from acting on the hinge point of the first connecting rod.

[0008] A further setting of the present utility model: two groups of the second suction nozzles are oppositely arranged and located on the opposite sides of the first suction nozzle. Third swing arms are provided on both the support plate I and the support plate II, and two groups of the second connecting rods are also oppositely arranged and correspond one by one.

[0009] With the above technical solution, with the assistance of two groups of second suction nozzles, it can be more stable when opening the box and supporting.

[0010] A further setting of the present utility model: the first swing arm is guided and adjusted on the second rod body, the second swing arm is guided and adjusted on the first rod body, the support plate I is guided and slid on the first rod body, the second connecting rod corresponding to the support plate I is guided and slid on the mounting rack, and a locking structure for locking after the guiding and adjusting of the first swing arm, the second swing arm, the support plate I and the second connecting rod is further included.

[0011] With the above technical solution, the positions of the first suction nozzle and the second suction nozzle can be adjusted relatively, so as to be suitable for use with paper boxes of different specifications.

[0012] A further setting of the present utility model: an adjusting screw is rotatably provided on the frame, and the adjusting screw is in threaded cooperation with the support plate I.

[0013] With the above technical solution, by rotating the adjusting screw, the support plate I can be driven to adjust. The structure is simple and the adjustment is relatively delicate. Description of the Drawings

A first suction nozzle 10 is arranged on the support plate 9. A second swing arm 20 that rotates synchronously with the first rod body 51 is provided on the first rod body 51. A first connecting rod 30 is hinged on the second swing arm 20. The other end of the first connecting rod 30 is hinged on the support plate 9. At least one of the support plate I 3 and the support plate II 4 is rotatably provided with a third swing arm 40. A second suction nozzle 50 that swings synchronously with the third swing arm 40 is provided on the third swing arm 40. A swing block 60 extending backward is provided on the first swing arm 8. A mounting bracket 70 is arranged on the swing block 60. A second connecting rod 80 is hinged on the mounting bracket 70. The other end of the second connecting rod 80 is hinged on the third swing arm 40. The second suction nozzle 50 is located at the side rear of the first suction nozzle 10. When the first swing arm 8 swings, the swing block 60 can drive the second connecting rod 80 to work, so that the second suction nozzle 50 rotates and adsorbs on the side of the carton.

[0023] With the above technical solution, during use, the driving member II 7 drives the second rod body 52 to rotate, which can rotate the first suction nozzle 10 to the carton storage bin 2, so as to adsorb the bottom of the carton. At this time, the driving member II 7 drives the second rod body 52 to turn over, and the carton can be taken out. At the same time, the swing block 60 will drive the mounting bracket 70 to swing, so that the second connecting rod 80 pushes the third swing arm 40 to rotate, and the second suction nozzle 50 moves to adsorb on the side of the carton. At this time, the driving member I 6 drives the first rod body 51 to rotate, so that the second swing arm 20 drives the first connecting rod 30 to work, so that the support plate 9 rotates relatively. Because the second suction nozzle 50 does not move, the first suction nozzle 10 can open the carton during relative movement, and with the assistance of the second suction nozzle 50, the opened carton can be prevented from closing, which is convenient for later packing and feeding. And it is supported by the support rod 5 horizontally arranged between the support plate I 3 and the support plate II 4, and its stability is relatively good. And the support rod 5 has a first rod body 51 that can rotate relatively and a second rod body 52 sleeved on the first rod body 51. The actions of taking the carton and opening the carton can be realized by the relative rotation of the first rod body 51 and the second rod body 52, and the practicability is stronger.

[0024] When the pallet 9 rotates to the supporting state, a supporting surface 100 for supporting the pallet 9 is further provided on the first swing arm 8, which can hold the pallet 9, thereby preventing all the forces from acting on the hinge point of the first connecting rod 30.

[0025] Two groups of the second suction nozzles 50 are oppositely arranged and located on the opposite sides of the first suction nozzle 10. Third swing arms 40 are provided on both the support plate I3 and the support plate II4. Two groups of the second connecting rods 80 are also oppositely arranged and correspond one by one. With the assistance of the two groups of the second suction nozzles 50, it can be made more stable when opening the box and supporting.

[0026] The first swing arm 8 is guided and adjusted on the second rod body 52, the second swing arm 20 is guided and adjusted on the first rod body 51, the support plate I3 is guided and slid on the first rod body 51, and the second connecting rod 80 corresponding to the support plate I3 is guided and slid on the mounting bracket 70. A locking structure (the locking structure is most preferably locked by screws or bolts) is further included for locking after the guiding and adjustment of the first swing arm 8, the second swing arm 20, the support plate I3 and the second connecting rod 80, so that the positions of the first suction nozzle 10 and the second suction nozzle 50 can be relatively adjusted, thereby being applicable to cartons of different specifications for use.

[0027] An adjusting screw rod 90 is rotatably provided on the frame 1. The adjusting screw rod 90 is in threaded cooperation with the support plate I3. By rotating the adjusting screw rod 90, the support plate I3 can be driven for adjustment. The structure is simple and the adjustment is relatively precise.
