Description

Technical Field

[0001] The invention relates to the technical field of carton sealing machines, in particular to a full-automatic rapid carton sealing machine. Background Art

[0002] The fully automatic rapid carton sealing machine is a highly efficient packaging equipment that can automatically complete the sealing operation of cartons. The characteristics of the fully automatic carton sealing machine include high efficiency, labor saving, improved packaging quality and strong adaptability. It can meet the needs of different production lines. They are widely used in electronics, food, home appliances, logistics and other industries. It is an indispensable equipment in modern automated packaging production lines.

[0003] When sealing a box, existing carton sealing machines usually use a single set of tape to achieve sealing, which may result in poor overall strength and pressure resistance of the carton seal, increase the risk of seal cracking during transportation and handling, and make it difficult to ensure that thinner or weaker tapes provide sufficient sealing effect. In addition, when increasing the sealing strength, some equipment finds it difficult to complete the adhesion of multiple sets of tapes at one time, which increases the number of adjustments to the carton sealing machine and reduces the continuity and production efficiency of carton sealing.

[0004] In addition: when the existing carton sealing machine is cutting the tape, it is difficult to adjust the cutting distance, the practicality is relatively simple, and it is difficult to change the size of the gap between the blade and the tape, which may cause the tape to be damaged due to excessive pressure or incomplete cutting due to insufficient pressure. At the same time, it is difficult to make the blade always work under the best cutting conditions according to the tape of different thicknesses and materials, which reduces the cutting effect and production efficiency, and it is difficult to wear the blade due to long-term overload operation; when the existing carton sealing machine is cutting the tape, it is difficult to detect the blade distance, which may cause the blade to collide during the adjustment process, resulting in blade breakage;

[0005] Another problem is that it is difficult to detect the use of tape when the existing carton sealing machine is sealing the box, which may lead to inaccurate dimensions of the sealed box, increase material waste, and excessive use of tape, resulting in staff failing to replenish the tape in time, resulting in tape breakage;

[0006] Finally: before the existing carton sealing machine seals the box, it is difficult to adjust the length of the tape according to the actual size of the box, and the tape may be too long or too short, reducing the accuracy of sealing and the flexibility of the carton sealing machine.

[0047] Second, the staff puts the box 10 on the top of the first conveyor belt 1, so that the first conveyor belt 1 conveys the box 10, and then clamps the box 10 through the clamping plate 3, and then clamps the tape through the three sets of clamping detection mechanisms 713.
