Description

Technical Field

[0001] This utility model belongs to the technical field of fully automatic packaging machines, and more specifically, it relates to an over-discharge detection device for a fully automatic packaging machine. Background Technology

[0002] The continuous development of packaging technology has laid a solid foundation for the emergence of desiccant packaging machines. Early simple filling and sealing equipment provided valuable reference and technical reserves for the realization of desiccant packaging machine functions. As people gradually mastered basic technologies such as quantitative filling and sealing, fully automatic packaging machines were born. However, existing fully automatic packaging machines have serious problems during operation; packaging bags are prone to excessive entanglement, leading to machine jamming. Once this happens, the machine must be stopped for cleaning and maintenance, which undoubtedly causes production interruption, shortens the effective working time of the packaging machine, and seriously affects overall production efficiency. To solve this problem, sensors with infrared detection functions were designed to monitor the operating status of the packaging machine, determine if there is excessive entanglement, and protect the equipment by starting and stopping it. However, in actual long-term use, it has been found that start-stop protection cannot fundamentally solve the problem of excessive entanglement of packaging bags during heat melting.

[0003] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided an over-exploitation detection device for a fully automatic packaging machine. Utility Model Content

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] This invention provides an over-fill detection device for a fully automatic packaging machine. Equipped with a heat-sealing and separation actuator, the pressing operation ensures that the plastic bag separates smoothly and completely from the heat-sealing assembly after heat sealing, preventing partial adhesion of the plastic bag to the heat-sealing assembly and thus avoiding tearing or damage to the seal. This guarantees the sealing quality of each plastic bag, ensuring good product packaging sealing and effectively preventing leakage, moisture absorption, oxidation, and other problems, extending the product's shelf life. Furthermore, once the plastic bag is completely separated from the heat-sealing assembly, it avoids the abnormal situations such as jamming or pulling that can occur during subsequent operation due to partial adhesion, reducing the incidence of equipment failure. This helps reduce downtime and maintenance time and costs, improves the overall operating efficiency and reliability of the equipment, and ensures continuous production.

[0020] This invention provides an over-packaging detection device for a fully automatic packaging machine. The device utilizes a pneumatic spray separation assembly mounted on the separation execution assembly. Driven by this assembly, the device uses sprayed gas to assist in preventing the sealed bags from sticking and detaching. Compared to traditional methods relying on natural cooling or simple mechanical separation, this more effectively prevents the sealed bags from sticking together, ensuring the integrity and smoothness of the separation, thus improving packaging quality. It integrates multiple functions such as heat sealing, separation, and pneumatic spray assistance, reducing the number of independent components required in the packaging machine and lowering equipment costs and maintenance complexity. Furthermore, the synergistic effect of multiple functions helps improve the smoothness and reliability of the entire packaging process, reducing potential malfunctions caused by improper coordination between different components.

A preliminary feeding tank 18 is provided above the feeding mixing tank 17. A feeding pipe 13 is inserted and connected to the preliminary feeding tank 18.

[0051] Specific usage method of this utility model:

[0052] When using this equipment, first install it on the deoxidizer production and packaging line. First, install the sealing bags 29 on the production line below the feeding funnel 26, ensuring the sealing bags 29 form a closed loop. Then connect the feeding pipe 13 to the infeed pipe. When the equipment is in use, the drive motor 20 located inside the base 11 starts running. After the drive motor 20 starts running, it drives the rotating disk 24 and the rotating drive column 25 to rotate. When the rotating disk 24 and the rotating drive column 25 rotate, they drive the sealing extrusion plate 19, the feeding funnel 26, and the heating drive assembly 21 to rotate. And when the feeding funnel... When the hopper 26 and the sealing extrusion plate 19 are rotating, the stirring and discharging plate 22 located at the end of the rotating drive column 25 will also rotate. When the stirring and discharging plate 22 rotates, it will stir the deoxidizer inside the feeding mixing tank 17 and enter the feeding funnel 26. Then, it will enter the sealing bag 29 through the feeding funnel 26 for sealing. During the sealing process, the heating drive component 21 will extend through the telescopic motor 31 to unfold and flatten the sealing heating shell 32, thereby separating the sealing bag. The retraction of the telescopic motor 31 will cause the sealing heating shell 32 to retract and contact the sealing extrusion plate 19 through the sealing heating plate 34, thereby sealing the sealing bag.

[0053] When the plastic seal detaches from the plastic bag, the prolonged heating of the plastic sealing heating plate 34 and the plastic bag can lead to excessive weakening of the seal during use, potentially causing the seal to stick to the plastic sealing heating plate 34. Therefore, during operation, the rotary motor 39 located inside the plastic sealing heating shell 32 is first activated, causing its first threaded rod 40 and second threaded rod 41 to move closer together. When the first threaded rod 40 and the second threaded rod 41 approach each other, they drive the second support rod 36 and the first support rod 35 to move closer together. When the second support rod 36 and the first support rod 35 approach each other, they compress and drive the compression cylinder 42 to spray air. During the air spray, air is blown onto the plastic seal of the plastic bag, lifting it up, and the plastic sealing heating plate 34 will... The rotary motor 39 moves closer to the rotary motor 39, while the fixed outer ring 33 moves away from the rotary motor 39. When the fixed outer ring 33 moves away from the rotary motor 39, it presses the outer ring of the plastic-sealed bag. The plastic-sealing heating plate 34 releases the plastic seal and, with the help of air blowing, achieves better release and effective heat dissipation. When the fixed outer ring 33 releases after pressing, the plastic-sealing heating plate 34 releases the plastic seal. When the fixed outer ring 33 and the plastic-sealing heating plate 34 release the plastic seal simultaneously, the equipment will control the drive rotary motor 20 to rotate according to the set distance. After rotation, it will seal the unsealed plastic-sealed bag. This equipment has only one sealing position, which is located on the side of the feed inlet of the feed protection trough 28.
