AI Technical Summary
In existing packaging equipment, the outer surface film is easily wrinkled and unevenly distributed after lamination, resulting in some parts of the film not being fully adhered to the surface of the waterproof membrane after heat shrinking, making it easily damaged.
A preheating hot melt film cutting mechanism is set in the packaging device, including a lower support plate and a lower pressure film cutting plate. The hot air mechanism and hot air through holes are used to pre-shrink the outer film before wrapping to ensure that the film adheres to the surface of the roll material. A semi-circular structure adapted to the roll material and a flexible heat insulation sleeve are used to reduce the wind speed.
This ensures a more uniform adhesion of the outer membrane before heat shrinking, reduces wrinkles, and guarantees that the outer membrane evenly covers the waterproof membrane after heat shrinking, preventing damage.

[0027] Figure 1 、 Figure 2 The preheating hot melting film cutting mechanism of the asphalt waterproofing membrane packaging device is arranged at the discharging end of the outer film wrapping mechanism, and comprises a lower support plate 41 and a lower pressing film cutting plate 42. The front end of the lower support plate 41 on both sides is rotationally connected to the fixed plate 6 arranged at both ends thereof through a rotating shaft. The rear end of the lower support plate 41 on both sides is rotationally connected to the hydraulic pushing mechanism 7 for controlling the overturning of the lower support plate 41 through a rotating shaft. The front end of the top surface of the lower support plate 41 is provided with a cutting groove 411. The hot melting film cutting knife 421 is arranged on the bottom surface of the lower pressing film cutting plate 42 opposite the cutting groove 411. The top of the lower pressing film cutting plate 42 is connected to the hydraulic pushing mechanism 7 for pushing downward. The hot air mechanism 9 is arranged below the lower support plate 41 and above the lower pressing film cutting plate 42. The hot air through holes are uniformly arranged on the surface of the lower support plate 41 and the surface of the lower pressing film cutting plate 42.
[0028] When the waterproofing membrane is wrapped with the outer surface film by the outer film wrapping mechanism, it will directly fall on the lower support plate, and then the lower pressing film cutting plate is pressed downward. After the lower pressing film cutting plate is pressed into place, the hot melting film cutting knife on the bottom surface of the lower pressing film cutting plate can complete the film cutting operation. In the present scheme, the pre-shrinking structure, i.e. the hot air mechanism and the hot air through holes, is arranged at the lower support plate and the lower pressing film cutting plate. The outer film wrapped on the surface of the waterproofing membrane is more closely attached to the surface of the waterproofing membrane by the hot air, so that the pre-shrinking of the outer film is realized. Thus, the outer film is less likely to wrinkle before entering the main heat shrinking mechanism, so that the outer film can more uniformly cover the waterproofing membrane after formal heat shrinking. Specific embodiment
[0029] The present embodiment further describes the lower pressing film cutting plate 42 and the lower support plate 41 based on the specific embodiment 1. The longitudinal section of the lower pressing film cutting plate 42 is circular after being pressed downward and attached to the lower support plate 41. The inner profile of the circular structure is adapted to the outer profile of the asphalt waterproofing membrane to be packaged.
[0030] In the present scheme, the semicircular structure is adopted as the lower support plate which is adapted to the waterproofing membrane. Thus, when the waterproofing membrane is wrapped with the outer surface film by the outer film wrapping mechanism, it will directly fall in the semicircular structure of the lower support plate, and then the lower pressing film cutting plate is pressed downward. After the lower pressing film cutting plate is pressed into place, the hot melting film cutting knife on the bottom surface of the lower pressing film cutting plate can complete the film cutting operation. Thus, the outer film cut and wrapped on the surface of the waterproofing membrane will not be too much, and can be well attached to the surface of the waterproofing membrane. Thus, the degree of heat shrinking is small during heat shrinking, and the problems of wrinkle and uneven heat shrinking are less likely to occur. Specific embodiment
[0031] The embodiment is further to the lower support plate 41 based on the specific embodiment 1, the lower part of the hydraulic pushing mechanism 7 for controlling the lower support plate 41 overturn is hinged with its fixed surface by hinged structure. Specific embodiment
[0032] The embodiment is further to the hot air mechanism 9 based on the specific embodiment 1, the hot air mechanism 9 includes hot air connecting pipe 91 and static pressure cover 92, the air inlet of the hot air connecting pipe 91 is connected with the hot air machine, the air outlet of the hot air connecting pipe 91 is connected with the static pressure cover 92, the static pressure cover 92 is respectively covered in the lower surface of the lower support plate 41 and the upper surface of the lower pressing type film cutting plate 42, the middle part of the rear vertical section of the hot air connecting pipe 91 for connecting with the lower pressing type film cutting plate 42 is provided with the expansion pipe 10.
[0033] The static pressure cover can reduce the wind speed, because the wind force can also affect the wrapping of the outer film, the middle part of the rear vertical section of the hot air connecting pipe for connecting with the lower pressing type film cutting plate is provided with the expansion pipe because the lower pressing type film cutting plate needs to be lifted and lowered. Specific embodiment
[0034] The embodiment is further to the expansion pipe 10 based on the specific embodiment 4, the inner wall of the expansion pipe 10 is provided with a flexible heat insulation sleeve, the top and bottom of the expansion pipe 10 are detachably connected with the pipe body of the hot air connecting pipe 91 through bolts.
[0035] Because the heat resistance of the expansion pipe is not so good, it is necessary to set a flexible heat insulation sleeve in the inner wall of the expansion pipe, which can stretch and contract with the expansion pipe and also play a heat insulation role, the top and bottom of the expansion pipe are detachably connected with the pipe body of the hot air connecting pipe through bolts, and such structure can facilitate the replacement of the expansion pipe and its internal structure.
[0036] Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to part of the technical features, any modification, equivalent replacement, improvement, etc. within the spirit and principles of the utility model should be included in the protection scope of the utility model.
