Therefore, those skilled in the art have provided a conveying device for carton die-cutting production to solve the problems mentioned in the background art. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5This utility model provides a technical solution for a conveying device for carton die-cutting production: a conveying device for carton die-cutting production includes a material rack 1 and a material placement slide rail 2. The number of material placement slide rails 2 is four sets, and the four sets of material placement slide rails 2 are installed in pairs symmetrically inside the support of the material rack 1. By using the combination of the material rack 1 and the material placement slide rail 2 as the material rack for cartons, the overall space occupied is smaller, and it can flexibly adapt to the on-site production environment.

[0026] The material rack 1 has a stacking and distributing mechanism installed inside its support along the unloading direction of the material placement slide rail 2. The stacking and distributing mechanism includes a rotating shaft 3 arranged symmetrically on both sides of the material rack 1 along the unloading direction of the material placement slide rail 2. Each set of rotating shafts 3 has multiple rotating shafts 3. The outer side of the rotating shaft 3 is symmetrically provided with a stacking cardboard seat 4 facing the material placement slide rail 2. The top of the cardboard seat 4 is provided with a stacking step 41. By using the stacking step 41 on the stacking cardboard seat 4 to limit the cardboard boxes, the cardboard boxes are stacked and distributed one by one on the stacking cardboard seat 4. Then, the rotating shaft 3 drives the stacking cardboard seat 4 to swing back and forth, unloading the cardboard boxes and stacking the upper cardboard boxes again. Then, in this manner, the cardboard boxes are unloaded one by one in a constant state.

[0027] The back plate of the support of the material rack 1 is equipped with a flipping brake assembly for driving the flipping shaft 3. The flipping brake assembly includes a lifting electric push rod 8 installed on the back plate of the material rack 1 and a transmission gear 13 installed on one end of the shaft of the flipping shaft 3. The extension end of the lifting electric push rod 8 is equipped with a lifting frame 11, and the two sides of the frame of the lifting frame 11 are symmetrically equipped with transmission racks 12 that mesh with the transmission gear 13. The back plate of the support of the material rack 1 is symmetrically equipped with lifting guide rails 9 along the extension direction of the lifting electric push rod 8. The back plate of the support of the lifting frame 11 is symmetrically equipped with lifting slides 10 that guide the lifting guide rails 9. By controlling the extension and braking of the lifting electric push rod 8, and under the guidance and adaptation of the lifting guide rails 9 and the lifting slides 10, the lifting frame 11 is driven to extend and slide, which in turn drives the transmission rack 12 to extend and slide. By using the meshing transmission of the transmission rack 12 and the transmission gear 13, the lifting thrust is converted into rotational thrust, which serves as a driving source to drive the combination of the flipping shaft 3 and the stacking cardboard base 4 to flip back and forth, unloading the cartons layer by layer.

[0028] Inside the support of the material rack 1, a pushing fixture 5 is provided along the unloading direction of the stacking and distributing mechanism. The pushing fixture 5 includes a feeding platform 51 and a pushing electric push rod 52 installed on one side of the feeding platform 51. The telescopic end of the pushing electric push rod 52 is provided with a pushing frame 53, and a flat push seat 54 that passes through the table surface of the feeding platform 51 is arranged above the plate of the pushing frame 53. By controlling the telescopic braking of the pushing electric push rod 52, the combined braking of the pushing frame 53 and the flat push seat 54 is driven, pushing the carton on the pushing fixture 5 flat between the pressure conveying rollers 7 for roller pressing and conveying feeding.

[0029] A roller conveyor mechanism is provided on one side of the support frame 1 along the pushing direction of the pusher 5. The roller conveyor mechanism includes two sets of horizontally opposite side supports 6. Two sets of support seats 14 are symmetrically arranged above the supports of the side supports 6. Multiple sets of counter-pressure conveying rollers 7 are arranged symmetrically between the two sets of support seats 14. The counter-pressure conveying rollers 7 rotate in opposite directions through two sets of meshing gears 16. A central gear 18 is installed on one side of the support seat 14 directly opposite the adjacent counter-pressure conveying rollers 7. Each set of counter-pressure conveying rollers 7 has a roller shaft end that is connected to the central gear 18. The brake gear 17 meshes with the support base 14, and a brake motor 15 is provided on the other side of the support base 14 to drive one of the sets of counter-pressure conveying rollers 7. By controlling the brake motor 15 as the drive source, one of the sets of counter-pressure conveying rollers 7 is driven to rotate. Then, under the meshing transmission combination of the brake gear 17 and the intermediate gear 18, the adjacent counter-pressure conveying rollers 7 are driven to rotate synchronously. The opposing counter-pressure conveying rollers 7 rotate in opposite directions through the meshing gear 16. The carton is flat-pressed and fed in the manner of counter-pressure roller feeding. While the conveying is stable, it can also flat-press the carton to improve the accuracy of subsequent die-cutting.

[0030] The working principle of this utility model is as follows: When the carton is being die-cut and conveyed, the carton to be die-cut is placed between the material placement slide rails 2 in a stacked manner. Then, by controlling the extension and braking of the lifting electric push rod 8, the combination of the lifting frame 11 and the transmission rack 12 is driven to extend and slide. The meshing transmission of the transmission rack 12 and the transmission gear 13 is used to convert the lifting thrust into the rotation thrust, which drives the combination of the flipping shaft 3 and the stacking card seat 4 to flip back and forth. The carton is stacked and dispersed in a layered manner and flattened on the stacking card seat 4. While unloading the carton, the upper layer of carton is flattened again. Then, in this manner, the carton is unloaded one by one onto the pushing fixture 5 in a constant unloading state.

[0031] Furthermore, by controlling the extension and retraction braking of the electric push rod 52 in the pusher fixture 5, the combined braking of the pusher frame 53 and the flat push seat 54 is driven, and the carton on the pusher fixture 5 is pushed flat between the pressure conveying rollers 7 for roller pressing and conveying.

[0032] Furthermore, by controlling the brake motor 15 as the drive source, one set of counter-pressure conveying rollers 7 is driven to rotate. At the same time, the transmission combination of the brake gear 17 and the central gear 18 drives the adjacent counter-pressure conveying rollers 7 to rotate synchronously. The opposing counter-pressure conveying rollers 7 also rotate in opposite directions through the meshing gear 16. The carton is flat-pressed and conveyed by the counter-pressure roller feeding method. The conveying is stable and occupies less space, which can better adapt to the on-site production environment.

[0033] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
