Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of packaging carton production, in particular to a flattening device for producing environment-friendly packaging cartons. Background Technique
[0002] A carton is a container made of cardboard as raw material, usually used for wrapping goods and protecting articles. The volume and shape of the carton vary according to the size and shape of the goods contained. The carton is mainly made of cardboard, including corrugated cardboard, boxboard, etc. The cardboard is composed of multiple layers of paper laminated together, commonly three layers, five layers, seven layers, etc. The main function of the carton is to protect the contents from damage, while facilitating transportation, storage and display. The concept of flattening in carton production refers to compressing and flattening the cardboard that has undergone processes such as printing and die-cutting through a flattening device to make it reach a certain hardness and flatness to meet the needs of subsequent processing and use.
[0003] The patent document with the application number CN202122502986.0 discloses a flattening device for producing environment-friendly packaging cartons. Among them, it includes a base, a connecting seat is arranged directly above the base, a cylinder is arranged directly above the connecting seat, the cylinder is fixedly connected to the base through a support frame, the piston rod of the cylinder is fixedly connected to the connecting seat at the bottom, two symmetrically distributed pressing rollers are arranged at the bottom of the connecting seat, the pressing rollers are connected to the connecting seat through a set of mounting frames, and the mounting frames are rotatably connected to the connecting seat through torsion springs, and the pressing rollers are rotatably connected to the mounting frames. The utility model designs pressing rollers that gradually shift laterally, which can gradually unfold the carton and then flatten it during the flattening process, effectively avoiding the problem of cardboard folding, improving the processing effect and enhancing the processing efficiency. Based on the retrieval of the above patent and the combination with the existing flattening devices for packaging carton production in the prior art, it is found that when flattening the cardboard, the existing flattening devices may have uneven pressure distribution, resulting in poor flattening effect in some areas of the cardboard. The traditional flattening devices may have slow cardboard conveying speed and low production efficiency due to structural limitations, and do not meet the requirements of large-scale production. In addition, during the flattening process, the cardboard may be damaged due to excessive pressure or improper operation, especially for some environment-friendly cardboard with low strength.

Thus, it improves the flattening quality and appearance effect of the cardboard. The cooperation between the driving motor and the transmission mechanism (the first transmission belt, the transmission rod, and the second transmission belt) in the pressing mechanism realizes efficient energy transfer and cardboard transmission, significantly improving the running speed and efficiency of the production line and meeting the requirements of large-scale production.
[0015] 2. In this utility model, a buffering mechanism is provided. The elastic structures (the first elastic body and the second spring body) in the buffering mechanism can provide appropriate elastic support during the flattening process, reducing the impact and damage to the cardboard body. Especially for environmentally friendly cardboard with relatively low strength, it effectively protects the integrity and usability of the cardboard. The design of the buffering mechanism allows for the adjustment of the elastic downward pressure. By adjusting the nuts and threaded rods, the compression degree of the spring body can be easily adjusted to adapt to cardboard of different thicknesses and hardnesses, thereby providing a more stable flattening effect. Through the adjustment function of the buffering mechanism, the flattening device can adapt to various cardboard of different specifications and materials. BRIEF DESCRIPTION OF THE DRAWINGS

A second transmission belt 706 is arranged behind the first transmission belt 704. The second transmission belt 706 is located outside the transmission rod 705. One end of the second transmission belt 706 away from the transmission rod 705 is looped around the pressing roller body 708;
[0028] The support seat 701 provides a stable support platform for the pressing mechanism 7, which helps to keep the position of the pressing roller body 708 fixed, thereby ensuring that the cardboard body 6 will not be deformed or damaged unnecessarily due to the movement of the mechanism during flattening. The motor bracket 702 is used to fix the driving motor 703 to ensure the stable and reliable operation of the motor during operation. The driving motor 703 is the power source of the pressing mechanism 7. It provides power to the transmission belt by rotating, and then drives the pressing roller body 708 to rotate to realize the flattening operation of the cardboard body 6. The first transmission belt 704 connects the driving motor 703 and the transmission rod 705. The transmission rod 705, as an intermediate transmission component, transmits the rotational movement of the first transmission belt 704 to the second transmission belt 706 to ensure the smooth operation of the entire transmission chain. The second transmission belt 706 receives the power of the transmission rod 705 and transmits it to the pressing roller body 708 to make the roller body rotate to complete the flattening task;
[0029] The buffer mechanism 8 includes a threaded rod 807, and an adjusting nut 809 is threadedly connected to the outside of the threaded rod 807.

[0031] The working principle of the present utility model is as follows: The flattening device for the production of the environmentally friendly packaging carton is additionally provided with a pressing mechanism 7 and a buffering mechanism 8. Before using the flattening device for the production of the environmentally friendly packaging carton, it is necessary to pre-connect the driving machine 4 and the driving motor 703 to the power supply and connect them to the control terminal. When using the flattening device for the production of the environmentally friendly packaging carton, first start the driving machine 4 to drive the driving rod 5 to rotate, and then drive the conveyor belt 3 to rotate, so as to achieve the effect of displacing the cardboard body 6. When the cardboard body 6 enters the pressing mechanism 7 and the buffering mechanism 8, under the pressing effect of the first spring body 808 and the second spring body 810 in the buffering mechanism 8, a downward pressure can be provided to the pressing roller body 708, so that the pressing roller body 708 can stably flatten the cardboard body 6. The driving motor 703 in the pressing mechanism 7 drives the first transmission belt 704 to rotate, and then drives the transmission rod 705 to rotate through the first transmission belt 704, so as to achieve the effect of driving the second transmission belt 706, and finally achieve the effect of driving the pressing roller body 708 to rotate. It can not only drive the displacement of the cardboard body 6, but also achieve the effect of flattening the cardboard body 6. In addition, by turning the adjusting nut 809, the elastic strength of the first spring body 808 can be adjusted, so as to achieve flattening effects of different strengths. To sum up, the pressing mechanism 7 and the buffering mechanism 8 complement each other. The pressing mechanism 7 adopts the method of pressing with a large roller, which can perform uniform flattening operation on the cardboard body 6 to achieve the effect of flattening the cardboard body 6. The buffering mechanism 8 adopts an elastic structure, which can provide an elastic downward pressing function, and can press the pressing roller body 708 in the pressing mechanism 7, so that the pressing roller body 708 tightly presses the cardboard body 6, and then achieves the effect of flattening the cardboard body 6. However, the elastic structure of the buffering mechanism 8 can be adjusted to adapt to cardboard bodies 6 of different specifications, so as to achieve a more stable flattening effect.
