Problems solved by technology

However, in the process of sealing at present, it is necessary to stop the movement of the profile in place before the sealing operation can be performed, otherwise the sealing effect will be poor
Re-transport the profiles after sealing, which leads to slow speed and low efficiency when packaging a large number of profiles
In addition, the position of the seal is not particular at present, and when the profile covered with the heat-shrinkable film passes through the area with a higher temperature after sealing, the heat-shrinkable film will gradually shrink when heated, and when the front part shrinks, the heat-shrinkable film that has not yet shrunk on the rear side will be removed. At this time, due to the random sealing position, the heat-shrinkable film after shrinking is still too long, or the heat-shrinkable film after shrinking is too short and is broken by the profile, both of which cause the heat-shrinkable film to wrap. good, bad product

Embodiment

[0032] The specific embodiment of the present invention is as Figure 1 to Figure 11 As shown, a profile heat shrinkable film end sealing device includes a sealing mechanism, the sealing mechanism is arranged on the sealing device support 51, and the front and rear sides of the sealing mechanism are respectively provided with a first profile conveying mechanism 9 and a second profile conveying mechanism 10. The sealing device support 51 is connected with a support drive mechanism 54 that makes it move back and forth along the profile conveying direction.

[0033] The sealing mechanism includes two sealing structures 53 respectively arranged on the upper and lower sides of the profile conveying path. Each sealing structure 53 includes two heating elements 533 that can approach and move away from the heat shrinkable film on the profile. In this embodiment, the heating elements 533 are electric heating tubes. The two heating elements 533 on the two sealing structures 53 corresp...

Abstract

The invention discloses a section heat shrinkage film end sealing method. Sectional materials are continuously conveyed forwards after being arranged to a heat shrinkage film in a sleeve mode, a gap is reserved between the front and back adjacent sectional materials, the heat shrinkage film between the front and back adjacent sectional materials is sealed through a sealing mechanism, and the sealing mechanism moves along with the sectional materials at the same speed and in the same direction during sealing. According to the section heat shrinkage film end sealing method, the sectional materials do not need to be stopped during the sealing, the packaging time is greatly saved, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the field of profile packaging, in particular to a method for sealing the end of a profile heat shrinkable film. 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 profile penetrates the cylindrical heat-shrinkable film and is transported forward. In order to facilitate the heat-shrinkable film to shrink and wrap the profile, it is necessary to seal the heat-shrinkable film between the front and rear adjacent profiles. However, in the process of sealing at present, it is necessary to stop the movement of the profile in place before the sealing operation can be performed, otherwise the sealing effect will be poor. After sealing, the profile is re-transported, which leads to slow speed and low effic...
