Abstract

The invention discloses a tension-adjusting type shrink film heating mechanism which comprises a feeding device, a discharging device, a heating device, a clamping mechanism and a tension adjusting mechanism. The tension adjusting mechanism comprises an upper adjusting mechanism and a lower adjusting mechanism. The upper adjusting mechanism and the lower adjusting mechanism each comprise a feeding roller, a sliding rod, a locating plate and a locating assembly, wherein the sliding rod is installed on one side of the feeding roller, a moving groove is formed in the locating plate, the sliding rod is connected into the moving groove of the locating plate in a sliding manner, the sliding rod in the upper adjusting mechanism is shorter than the sliding rod in the lower adjusting mechanism, and the sliding rod and the locating plate are fixed through the locating assembly. By means of telescopic moving of the sliding rods in the upper adjusting mechanism and the lower adjusting mechanism, the length of the upper sliding rod and the length of the lower sliding rod are adjusted to be different, so that the purpose of adjusting tension of shrink films is achieved.

Description

technical field [0001] The invention relates to a tension-adjustable shrink film heating mechanism. Background technique [0002] At present, shrink film is used to wrap the outside of the product or package, and after heating, the shrink film shrinks and wraps the product or package tightly, fully displaying the appearance of the item, improving the displayability of the product, and increasing its beauty and sense of value. The items packed by the heat shrink machine can be sealed, moisture-proof, pollution-proof, and protect the goods from external impact, and have a certain buffering property, especially when packing fragile items, it can prevent the utensils from scattering when they are broken. In addition, the possibility of products being dismantled and stolen can be reduced. The existing heat shrinkable film packaging machine is transported by a conveyor belt during packaging, or conveyed by a rotating roller in a heating box. Due to the contact between the shrinka...
