Cold storage panels often need to be packaged with soft films before they are sold to prevent scratches, wear, weather factors, etc. from damaging their surface, while meeting customers' requirements for comfortable appearance. Existing packaging is mostly manual packaging, folding and bonding, which is inefficient and easy to fall off from the bonding point. The packaging effect is unstable and may affect the surface appearance and storage and transportation. There are also some mechanical packaging, which is only wrapped by rotation and winding, tied with a knot at the end or glued with glue, which has poor adhesion and is easy to loosen and fall off, causing losses. Summary of the invention

[0003] The purpose of the utility model is to overcome the above disadvantages and provide a packaging heat sealing device, which improves the end of packaging and has the advantage of stability after packaging.

[0004] The purpose of the utility model is achieved through the following technical scheme: a metal-faced sandwich panel packaging heat sealing device, comprising an installation outer frame, wherein four telescopic cylinders are arranged in the installation outer frame, one end of the telescopic cylinders is fixed to the rear end of the installation outer frame, and the other ends of the four telescopic cylinders are respectively connected to an upper bonding plate, a lower bonding plate, an upper fixed plate and a lower fixed plate, four slide rails are respectively installed on the vertical four sides of the installation outer frame, two of which are respectively connected to the upper bonding plate and the upper fixed plate through sliders, one side of the upper fixed plate is a metal part, and an electrically conductive copper wire is installed under the wooden part on the lower surface of the metal part, and a heating plate is provided on the top of the upper bonding plate and the lower bonding plate, and the other two slide rails are connected to a welding assembly through a slider, and the two welding assemblies are respectively connected to the lower bonding plate and the lower fixed plate, and cylindrical springs are provided between the welding assembly and the lower bonding plate, and between the welding assembly and the lower fixed plate, and a roller is installed on the front end cross bar of the installation outer frame, and an inclined guide surface is provided at the lower end of the lower fixed plate and the lower bonding plate, and the roller is placed on the inclined guide surface.

[0005] A further improvement of the utility model is that the mounting outer frame is mounted below the conveyor belt of the baler.

[0006] A further improvement of the utility model is that a photoelectric sensor is arranged on the outer side of the mounting frame.

[0007] A further improvement of the utility model is that a concave rubber strip is provided on the upper surface of the lower fixed plate, and a convex metal strip is provided on the lower surface of the upper fixed plate.

[0008] Compared with the prior art, the utility model has the following advantages:

[0009] When the continuous production line of metal-faced sandwich panels is working, the panels are sent out by the conveyor belt, then wrapped and packaged by the baler, automatically cut off at the end, and heated and bonded to the edges. There is no need to wait for the winding to be completed for mechanical or manual secondary packaging and bonding.

[0010] When the continuous production line of metal-faced sandwich panels is working, after packaging and cutting, except for the part of the heat shrink film adhered to the packaging surface, the other part is fixed between two fixed plates. Through the rotation of the packaging machine, it can be directly packaged with the next stack of panels, avoiding the need to stop the conveyor belt during the packaging process and manually wrap the heat shrink film to start packaging.

[0011] At the end of packaging, the tail end of the packaging film is heated and adhered, and the residual heat drives the film at the end to shrink, making it tighter and more beautiful as a whole, avoiding the packaging film from falling off after being cut, being entangled in the conveyor belt, or the whole packaging falling apart from one end.
