Embodiment Construction

[0020] Such as figure 1 and figure 2 As shown, a packaging film forming device includes three heating mechanisms 1 arranged on the heating station and a forming mechanism 2 arranged adjacent to the three heating mechanisms 1 on the forming station, the heating station and the forming The workstations are adjacent.

[0021] Heating Mechanism 1

[0022] Such as figure 1 As shown, the heating mechanism 1 includes an upper heating chamber 11 and a lower heating chamber 12 which respectively heat the upper and lower sides of the packaging film. , the lower heating chamber 12 can move vertically up and down. When the lower heating chamber moves upward and contacts with the upper heating chamber, the upper and lower heating chambers form a closed space, and the packaging film clamped between them is up and down. Heating on both sides, here the above heating chamber is taken as an example to introduce.

[0023] The upper heating chamber 11 includes first to third heating plates ...

Abstract

The invention relates to a packaging film forming device which comprises at least one heating mechanism 1 for heating a packaging film. Each heating mechanism 1 comprises an upper heating chamber 11 used for heating the upper surface of the packaging film and arranged fixedly, and a lower heating chamber 12 used for heating the lower surface of the packaging film and capable of moving up and downperpendicularly; and when each lower heating chamber 12 moves upwards so as to be combined with the corresponding upper heating chamber 11, the upper surface and the lower surface of packaging film clamped between each upper heating chamber and the corresponding lower heating chamber are heated. Therefore, when each lower heating chamber moves upwards so as to be combined with the corresponding upper heating chamber, the double surfaces of the packaging film clamped between each upper heating chamber and the corresponding lower heating chamber are heated, so that the packaging film is heated quickly, and a forming effect is good.

Description

technical field [0001] The invention belongs to the technical field of packaging equipment, in particular to a packaging film forming device. Background technique [0002] When the thickness of the packaging film is relatively thick, generally greater than 0.4mm, it is difficult to be heated rapidly in a short time (generally 1-2S) due to the poor thermal conductivity of the packaging film. Generally, the side of the packaging film that is in contact with the heat source (heating plate) can quickly reach the predetermined temperature, but the non-contact side is difficult to reach the predetermined temperature in a short time due to the poor thermal conductivity of the packaging film, even if the heated side passes through for a long time. Time heating (heating time even up to 10S), the heated surface shows signs of melting, and the non-heated surface has just softened, so the forming effect of the formed packaging box or packaging bag is not good.
