Description

The contact packing equipment for thermal shrinkage and the method

The present invention relates to a heat shrink tight packing apparatus and method for closely packing a heat shrink film finally packaged on a pack product such as cigarette, and more particularly, pack products wrapped around the outside with a heat shrink film into a heat shrinkable part. Continuously injected input unit, a heat shrinking unit in which the heat shrinking film is uniformly and thermally shrinked while the heat is directly transferred to the heat shrinking film wrapping the outside of the pack product, and a control unit for controlling the temperature of the heating element of the heat shrinking unit. And it relates to a heat shrink tight packing apparatus and method characterized in that the transfer portion is to be transported and discharged to the discharge portion continuously by the belt transmission means to the pack product introduced into the heating shrinkage portion.

In general, products such as cigarettes, pharmaceuticals, confectionery, chewing gum, etc. are packed primarily with paper, and then heat shrinked to maintain the confidentiality and moisture content of the contents during storage and distribution. The film is packaged using a film. When packaging the product using a conventional heat-shrink film, the product is packaged in a manner using heat convection. Such a device is a high-temperature heated air to closely package a product wrapped with a heat shrink film. The heat shrink film that wraps the surface of the product shrinks when the product wrapped with the heat shrink film is introduced into the heating chamber with the heating chamber emitting the heat and the heated air inside the heating chamber forms airflow on the entire surface of the product due to convection. Although the product is to be closely packed, such convection shrinkage packaging may cause the film to Since the heat does not flow evenly on the sieve surface, and the heat in the lower part is relatively low in temperature compared with the heat moving to the upper part of the product due to convection, the upper and lower parts of the product are not uniformly heat-shrunk and wrapped. Since the heat shrink film must always be maintained at a suitable temperature to shrink, the energy consumption is too high, and the close packaging using the convection phenomenon as a method of supplying heat has a problem that it is not suitable to quickly pack a large amount of products.

The present invention is to solve this problem to ensure that the heat shrink film shrinks uniformly and tightly on the surface of the pack product when the outer packaging of the pack product, by reducing the energy consumption by using a heat conduction method, close to a large number of products quickly The purpose is to make the packaging.

In order to achieve the above object, a pack product wrapped around the outside with a heat-shrink film is stacked and introduced into the pack, and the plurality of stacked products are divided up and down by side guide plates having a split guide, and are divided and supplied into the heat shrinking unit. The pack part and the pack product divided into the upper and lower parts through the input part are respectively heated by the heating element while passing through the heating shrinkage transfer paths of the upper and lower parts, each of which is provided with a heating element, a temperature sensor and a heating feed roller. The heat shrinking part is heat-converted directly by the heat transfer roller to the heat-shrink film wound on the pack product, and the heat shrinking film is uniformly and tightly heat shrinked, and the pack product introduced into the heat shrinking part is continuously connected by belt transmission means. A transfer unit configured to transfer and discharge the discharge unit to the discharge unit, and heat generation of the heating contraction unit And control unit for controlling the temperature of, and that is characterized in that is composed of a discharge.

Pulleys 44a, 44b, 44c, 44d and length adjusting bars 27a, 27b and rear pulleys 55a, 55b, 55c and 55d of the heat shrinkage transfer paths 18a and 18b. Heat-shrink tight packaging device characterized in that it is installed in a triangular shape so as to pass. In the method of closely packing the heat shrink film wrapped around the outside of the pack product, if the pack product (3) wrapped around the outside with the heat shrink film (2) is stacked in multiple stages and continuously supplied to the feed section (8) The pack products 3 stacked by the split guides 12a and 12b formed on the side guide plates 10a and 10b of the upper and lower parts are respectively divided into upper and lower portions, and the heat shrinkage portion (5a) and (5b) are provided. 13) The pack product 3, which is dividedly supplied into the inside and supplied into the heat shrinking unit 13, is a heat shrink transfer path 18a and an intermediate heat shrinkage between the upper heat shrink plate 14 and the intermediate heat shrink plate 15. Along the outer periphery of the length adjusting bars 27a and 27b on the left and right sides of the heat shrinkage transfer paths 18a and 18b while passing through the heat shrinkage transfer path 18b between the plate 15 and the lower heating shrinkage plate 16. The belt 40a, 40b, 40c, 40d is continuously discharged toward the discharge openings 6a, 6b and at the same time, the upper and lower surfaces of the heat shrinkage transfer paths 18a, 18b. The outer surface of the pack product 3 is wrapped in a plurality of heat transfer rollers 21a, 21b, 21c, and 21d respectively provided on the surface and heated to a constant temperature by the heating elements 19a, 19b, and 19c. The heat shrink film 2 is in close contact and heat is directly transferred from the plurality of heat transfer rollers 21a, 21b, 21c, and 21d so that the heat shrink film 2 is uniformly and taut to the outside of the pack product 3. A heat shrinkable packaging method characterized in that the packaging closely. In the apparatus for tightly packing the heat shrink film wrapped around the outside of the pack product, the heat shrink portion 13 and the transfer portion 36 is provided inside the inlet (5a), outlet 6a and the heat release groove (56) The formed outer housing 4, the lower guide plate 9, the side guide plate 10a and 10b and are provided so that the pack products 3 are formed in the heat shrinkage section 13 in a row.
