Compared with the cylinder method, it has less noise, stable operation, and adjustable expansion and contraction speed.

[0023] 6. The utility model is provided with a circulating transition mechanism between the feeding mechanism and the box feeding mechanism. On the one hand, it can make up for the gap between the feeding mechanism and the box feeding mechanism, avoiding the affected material being pushed and unable to be smoothly pushed into the box due to this gap. On the other hand, the circulating transition mechanism can play a role in guiding and limiting the pushed material, avoiding the collision between the material and the packaging box.

Detailed Description of the Preferred Embodiment

[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0032] As a preferred embodiment of the present utility model, referring to the accompanying specification Figure 1As shown in the figure, this embodiment discloses a high-speed cartoning machine, which includes a carton feeding mechanism 1, a material feeding mechanism 2, and a material pushing mechanism 3. The carton feeding mechanism 1 is located on one side of the material feeding mechanism 2, and the material pushing mechanism 3 is located on the other side of the material feeding mechanism 2; the conveying speed of the carton feeding mechanism 1 is matched with that of the material feeding mechanism 2. During the operation of the carton feeding mechanism 1 and the material feeding mechanism 2, the material pushing mechanism 3 pushes the material conveyed on the material feeding mechanism 2 into the packaging box conveyed on the carton feeding mechanism 1; the material pushing mechanism 3 includes a power execution mechanism 4 and a material pushing rod assembly. The power execution mechanism 4 has at least two degrees of freedom. The power execution mechanism 4 includes a static platform 6, a moving platform 7, a transmission component 8, and a servo drive component 9. The servo drive component 9 drives the moving platform 7 to reciprocate relative to the static platform 6 at least in two directions along the conveying direction of the material feeding mechanism 2 and perpendicular to the conveying direction of the material feeding mechanism 2 through the transmission component 8; the material pushing rod assembly is assembled on the moving platform 7.

[0033] In this embodiment, the power execution mechanism 4 with at least two degrees of freedom is used as the driving power mechanism of the material pushing rod assembly. The power execution mechanism 4 can realize the movement in two directions of the X and Y axes within its working space, which can make the movement stroke and trajectory of the material pushing rod 5 be a parabola or an arc-shaped trajectory. For the adjustment of the stroke and trajectory of the material pushing rod 5, it only needs to control the driving motor of the power execution mechanism 4 to achieve. The structure is simple, the stroke and trajectory of the material pushing rod 5 are adjustable, and the versatility is better. Even after the material specifications change, it can still be used.

[0034] As an implementation manner of this embodiment, referring to the attached Figure 2 drawing and the attached Figure 3 drawing as shown, a material pressing drive component is assembled on the moving platform 7, and a material pressing plate 10 is assembled on the material pressing drive component. The material pressing drive component drives the material pressing plate 10 to reciprocate relative to the material pushing rod 5. When the material pushing rod 5 pushes the material, the material pressing plate 10 extends out above the material pushed by the material pushing rod 5, and after the material pushing plate and the material enter the packaging box, the material pressing plate 10 is withdrawn from the packaging box and resets together with the moving platform 7 and the material pushing rod 5.

[0035] In this embodiment, the utility model is provided with a press plate 10 above the push rod 5. Through the setting of the press plate 10, it is possible to press the material while pushing the material, so that when the material is pushed into the box, it can be better pushed into the packaging box to avoid the collision between the material and the packaging box and the impact of the box loading. The power actuator 4 of the utility model includes a moving platform 7, on which a press drive assembly can be assembled, so as to achieve the withdrawal of the press plate 10 after entering the packaging box. When the press plate 10 of the utility model pushes the material together with the push rod 5, the press plate 10 is located above the material and enters the packaging box together with the material. After that, driven by the press drive assembly, the press plate 10 is withdrawn from the packaging box. After the press plate 10 is withdrawn from the packaging box, it is reset together with the moving platform 7 and the push rod 5. This arrangement can ensure that when the press plate 10 is withdrawn, the material is blocked by the push rod 5, so as to avoid the material being taken out of the packaging box by the withdrawn press plate 10.

[0036] As an example, the press drive assembly includes a press drive motor 11, a press screw 12 and a press transmission frame 13. The press drive motor 11 drives the press screw 12 to rotate. The press screw 12 is rotatably mounted on the moving platform 7 through a bearing mounting seat. The press transmission frame 13 is slidably mounted on the moving platform 7. The press transmission frame 13 is threadedly connected to the press screw 12. The press screw 12 rotates back and forth, driving the press transmission frame 13 to move back and forth on the moving platform 7.

[0037] Furthermore, in order to facilitate the layout, the pressing drive motor 11 and the pressing screw 12 are connected by a synchronous belt assembly 14 .

[0038] As an example of this embodiment, the number of the pressing plates 10 is the same as the number of the pushing rods 5 , and both are fixedly assembled on the pressing transmission frame 13 .

[0039] Further preferably, the push rod assembly includes four push rods 5, and the four push rods 5 are arranged in parallel and spaced apart on the moving platform 7. Multiple push rods 5 can improve the box loading efficiency.

[0040] As another example, the material pressing drive assembly can be implemented by using a cylinder or a synchronous belt drive assembly 8.

[0041] As an example of this embodiment, the power actuator 4 can be selected from XY linear modules, cross slides and other actuators. An XY linear module and an X linear module are assembled with a Y linear module. The X linear module is assembled on the static platform 6. The X linear module drives the Y linear module to reciprocate along the X axis. The moving platform 7 is arranged on the Y linear module. The Y linear module drives the moving platform 7 to reciprocate along the Y axis. Under the combined action of the X linear module and the Y linear module, the moving platform 7 can reciprocate relative to the static platform 6 in the X and Y directions. The structural principle of the cross slide is the same as that of the XY linear module. The X direction is parallel to the conveying direction of the feeding mechanism 2, and the Y direction is perpendicular to the conveying direction of the feeding mechanism 2.

[0042] As an example of this embodiment, the power actuator 4 has three degrees of freedom. On the basis of the above XY model, adding a Z-axis module can achieve three degrees of freedom, so that the moving platform 7 reciprocates in the X-axis, Y-axis and Z-axis directions. The Z-axis direction is the vertical direction.

[0043] As another example of this embodiment, the power actuator 4 can also be selected as a serial manipulator.

[0044] As a preferred implementation manner of this embodiment, referring to the appended Figure 2 and appended Figure 4 shown, the power actuator 4 is a two-axis parallel manipulator. Its structure runs stably and occupies less space. Compared with the XY-axis operation module, it occupies less space and is more conducive to layout. As an example, the two-axis parallel manipulator can be selected from long and short arm two-axis parallel manipulators, equal arm two-axis manipulators, etc.

[0045] As a preferred implementation manner of this embodiment, referring to the appended Figure 1 shown, a circulating transition mechanism 15 is arranged between the feeding mechanism 2 and the box feeding mechanism 1. The rotation speed of the circulating transition mechanism 15 is adapted to the box feeding mechanism 1 and the feeding mechanism 2. On the one hand, it can make up for the gap between the feeding mechanism 2 and the box feeding mechanism 1, and avoid the material to be pushed being affected by this gap and unable to be smoothly pushed into the box. On the other hand, the circulating transition mechanism 15 can play a role in guiding and limiting the material to be pushed, and avoid the material from colliding with the packaging box. Under the guiding and transitional action of the circulating transition mechanism 15, the material can be smoothly pushed into the packaging box.

[0046] As a specific implementation structure of this implementation manner, referring to the appended Figure 5As shown, the cyclic transition mechanism 15 includes two cyclic chains 16 and a cyclic drive assembly. The two cyclic chains 16 are assembled on the cyclic drive assembly and are driven to rotate by the cyclic drive assembly. A number of transition assemblies are assembled on the two cyclic chains 16. The transition assembly includes a first transition guide 17 and a second transition guide 18. The first transition guide 17 is fixed on one cyclic chain 16, and the second transition guide 18 is fixed on the other cyclic chain 16. The first transition guide 17 and the second transition guide 18 are arranged opposite to each other to form the transition assembly, and a transition channel for materials to pass through is formed between the first transition guide 17 and the second transition guide 18. By using two sets of cyclic chains 16, with the first transition guide 17 fixed on one cyclic chain 16 and the second transition guide 18 fixed on the other cyclic chain 16, the distance between the first transition guide 17 and the second transition guide 18 can be adjusted by adjusting the two sets of cyclic chains 16 to adapt to the change of material specifications. The cyclic transition mechanism 15 of the present invention has a simple structure and is easy to adjust.

[0047] Further, the cyclic drive assembly includes a cyclic drive motor, a first cyclic sprocket set, and a second cyclic sprocket set. One cyclic chain 16 is connected to the first cyclic sprocket set, and the other cyclic chain 16 is connected to the second cyclic sprocket set. Both the first cyclic sprocket set and the second cyclic sprocket set include a driving sprocket 19 and a driven sprocket 20. The driving sprockets 19 of the first cyclic sprocket set and the second cyclic sprocket set are assembled on the driving shaft, and the driven sprockets 20 of the first cyclic sprocket set and the second cyclic sprocket set are assembled on the driven shaft. The cyclic drive motor drives the driving shaft to rotate. This is convenient for assembly and adjustment.
