Description

Technical Field

[0001] The utility model belongs to the technical field of packaging equipment, and particularly relates to a linear square box sealing machine. Background Art

[0002] A sealing machine is a type of packaging production equipment used to seal pre-process products that require sealing. Existing fully automatic sealing machines can be divided into rotary and linear types. Most linear sealing machines are electromagnetic induction sealing machines, which require the sealing film to be cut and shaped in advance, then installed in the lid and then installed on the container. The film, lid, and container are integrated into a working unit and enter the sealing machine for sealing. This linear sealing machine uses the eddy current magnetic field generated when electromagnetic waves come into contact with metal materials, causing the metal material to instantly heat up to achieve the purpose of magnetothermal conversion. When the bottled container passes through the sealing machine's magnetic induction zone, the aluminum foil gasket inside the lid is detected by induction, and the metal attached to the gasket instantly becomes incandescent, melting the adhesive layer on the gasket to the bottle mouth and forming a whole, achieving the purpose of beautiful and firm product sealing.

[0003] Rotary-disc sealing machines typically use a single roll of sealing film. A film-pulling mechanism controls the film's movement to a designated station. A rotating motor drives the turntable, which transports the container to the sealing station. The machine then begins film cutting and heat-melting the film. This type of rotary-disc sealing machine utilizes the high temperature of a heated pressure head to melt the film cut by the cutter onto the bottle's opening, where it fuses together.

[0004] Currently, the rotary table sealing machines and linear sealing machines on the market have their own shortcomings. The linear sealing machines require pre-cutting of film and pre-installation of lids before sealing, and there is more preparatory work before formal sealing. The rotary table sealing machine omits the preparatory work before sealing and combines film cutting and sealing into the same process step. However, it cannot carry the lid when sealing. Therefore, although the preparatory work before sealing is omitted, the lid still needs to be installed after sealing, which has certain limitations. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] In this embodiment, when the container to be sealed is placed on the upper end of the conveyor belt 2 for transportation, the No. 1 intercepting box assembly 4 is used to intercept it. At this time, the detection light eye recognizes that the container to be sealed is in place, and then the conveyor belt 2 stops, the fixing device 27 extends to clamp the container to be sealed, and the sealing unit 9 rises and falls to perform film cutting and sealing. While the sealing unit 9 descends, the No. 2 intercepting box assembly 5 extends to intercept the subsequent container to be sealed. At this time, the No. 1 intercepting box assembly 4 is retracted to prepare to release the container on the sealing station.
