Problems solved by technology

However, the above method has the following defects: 1) The oven needs to be preheated first. Due to the large volume of the oven, it takes more than ten minutes to preheat, which takes a long time, and it also heats the profile while acting on the heat shrinkable film, and the energy consumption reaches more than 30KW. ; 2) Personnel need to be close to the oven with high temperature when carrying profiles, the working environment is relatively harsh, the physical energy consumption of personnel is large, and the safety is also low

Embodiment

[0036] The specific embodiment of the present invention is as Figure 1 to Figure 10 As shown, a profile heat shrinkable film heat shrinking device includes a device main body 1, and the device main body 1 includes a hot air nozzle 11 arranged outside the profile conveying path. The hot-blast spout 11 can be single, and the hot-blast spout 11 can also be set as a strip-shaped annular spout simultaneously; In addition, the hot-blast spout 11 also can be at least two and arranges around the profile delivery path, that is, each hot-blast spout 11 surrounds in a ring shape, so that The annular heating space where the profile cross section is located is evenly heated, or the hot air nozzles 11 can also be arranged spirally around the profile conveying path. The hot air nozzle 11 adopts the method of spraying hot air in a point shape, and in this embodiment, there are multiple hot air nozzles 11 arranged around the profile conveying path. The hot air nozzles 11 are arranged in mult...

Abstract

The invention discloses a heat shrinkage method for a sectional material heat shrinkage film. A hot air nozzle blows hot air to the surface of the heat shrinkage film sleeving the outer side of a sectional material, so that the heat shrinkage film is heated and shrunk to wrap the sectional material. The heat shrinkage method for the sectional material heat shrinkage film is low in energy consumption, convenient to operate and higher in safety.

Description

technical field [0001] The invention relates to the field of profile packaging, in particular to a heat shrinking method for profile heat shrinkable films. Background technique [0002] After the profile is treated with surface acid and alkali cleaning, in order to better protect its surface and reduce the problem of scratches caused by collision, the surface of the profile will be covered with heat shrinkable film before packaging. The traditional method of covering the surface of profiles with heat-shrinkable film is to cover multiple profiles with heat-shrinkable film, and then put them together in an oven equipped with electric heating tubes. There are many electric heating tubes distributed in the bottom and side walls of the oven. The power of each electric heating tube is about 1KW. The larger the oven, the more electric heating tubes need to be arranged, and the greater the overall power required. The inside of the oven is heated to 80-140°C in advance. In order to...
