[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0029] like Figure 1-Figure 6As shown, the present invention provides a guide, including: a triangle plate 1, a fixed strip 2, a pressure relief strip 3, a limit strip 4 and a fixing member 5, wherein the triangle plate 1 is used to guide the plastic film from the longitudinal direction to the transverse direction. The fixed strip 2 is connected to the triangle plate 1. The pressure relief strip 3 is fixed on the triangle plate 1, and is used to reduce the pressure exerted by the triangle plate assembly 1 on the plastic film. The limit strip 4 is fixed on the triangle plate 1, and is used to limit the transverse plastic film. The fixing member 5 is connected to the fixed strip 2, and the fixing member 5 cooperates with the fixed strip 2 to install and fix the triangle plate 1. The pressure relief strip 3 is arranged on the triangle plate 1, and the pressure relief strip 3 can reduce the pressure exerted by the triangle plate assembly 1 on the plastic film. During use, the plastic film is avoided from being scratched or even broken, so that the packaged plastic film can fit closely to the goods to be packaged, reducing manual adjustments, reducing labor costs, greatly improving production efficiency, and meeting large-scale production needs.

[0030] In a preferred embodiment, the triangle plate 1 is an isosceles right triangle structure, a weight-reducing hole is provided on the triangle plate 1 , and the fixing strip 2 is fixedly connected to one of the right-angled sides of the triangle plate 1 .

[0031] In a preferred embodiment, the pressure relief strip 3 is arranged on the edge of the other right-angled side of the triangular plate 1 and the edge of the hypotenuse of the triangular plate 1 .

[0032] In a preferred embodiment, the thickness of the pressure relief strip 3 is greater than the thickness of the triangle plate 1. The thickness of the pressure relief strip 3 is designed to be greater than the thickness of the triangle plate 1. Compared with the traditional method, it can reduce the pressure exerted by the triangle plate assembly 1 on the plastic film, and avoid scratching or even breaking the plastic film during use, so that the packaged plastic film can fit the packaged goods tightly, reduce manual adjustments, reduce labor costs, greatly improve production efficiency, and meet large-scale production needs.

[0033] In a preferred embodiment, the surface of the pressure relief strip 3 is a smooth arc structure. Preferably, the surface of the pressure relief strip 3 is a circular arc structure or an elliptical arc structure. Designing the surface of the pressure relief strip 3 to be a circular arc structure or an elliptical arc structure can reduce the pressure exerted by the triangular plate assembly 1 on the plastic film compared to the traditional method, and avoid scratching or even breaking the plastic film during use, thereby allowing the packaged plastic film to fit closely to the goods to be packaged, reducing manual adjustments, reducing labor costs, greatly improving production efficiency, and meeting large-scale production needs.

[0034] The present invention also provides a sealing and cutting machine, including a guide. The sealing and cutting machine adopts a guide with an improved structure, which avoids scratching or even breaking the plastic film during use, thereby allowing the plastic film to fit closely to the goods to be packaged, reducing manual adjustments, reducing labor costs, greatly improving production efficiency, and meeting large-scale production needs.

The input end of the heat shrinking machine 9 is connected to the output end of the sealing and cutting machine 8. The input end of the second conveying device 10 is connected to the output end of the heat shrinking machine 9. The lower platform 11 is connected to the output end of the second conveying device 10.

[0036] A stack of gypsum board samples is placed on the upper platform 6, and then automatically separated into individual sheets, and enters the sealing and cutting machine 8 through the transition conveyor of the first conveying device 7. The plastic film in the sealing and cutting machine 8 is guided from the longitudinal direction to the transverse direction by the guide, and the gypsum board sample enters the plastic film. After being cut by the cutter of the sealing and cutting machine 8, the gypsum board sample is completely wrapped in the plastic film. The sealed gypsum board sample is conveyed to the heat shrinking machine 9 through the sealing and cutting machine 8, and heat-shrunk in the heat shrinking machine 9. The heat-shrunk gypsum board sample is conveyed to the lower platform 11 through the second conveying device 10, and the boards are stacked on the lower platform 11, and the entire plastic sealing packaging process is completed.

[0037] By improving the guide structure, the automatic sealing and heat-sealing system of the gypsum board sample plate can avoid scratching or even breaking the plastic film during operation, so that the plastic film can fit closely to the gypsum board sample plate, reducing manual adjustments, reducing labor costs, greatly improving production efficiency, and meeting large-scale production needs.
