A cutting mechanism, equipment and process for the production of four-side sealed self-adhesive release deoxidizers

Abstract

A cutting mechanism, equipment and process for producing four-side sealed adhesive-backed deoxidizers according to the present invention include a pair of support frames. A shearing roller and a positioning roller are arranged in parallel between the support frames. A plurality of annular cutting knives are evenly distributed along the axial direction of the shearing roller. The annular cutting knives divide the shearing roller into several sections, and a plurality of rectangular cutting knives are evenly distributed in each section. Guide grooves for inserting the annular cutting knives one by one are arranged on the positioning roller. When in use, the present invention is directly taken from a strip-shaped deoxidizer or used in an automatic labeling form in cooperation with a product packaging production line such as a food packaging production line and pasted onto the packaging film of foods, etc. On the one hand, it avoids the risk of cutting and contaminating foods due to the automatic shearing and feeding of deoxidizers again during use on the packaging production line. On the other hand, because it is pasted on the inner layer of food packaging bags / containers, etc. after use, it can also effectively prevent it from being mixed with foods, resulting in the risk that consumers may accidentally ingest deoxidizers, desiccants, and preservatives when taking or pouring foods.

Description

Technical Field

[0001] The present invention belongs to the technical field of deoxidizers, and particularly relates to a cutting mechanism, equipment and process for producing a four-side sealed back-adhesive release deoxidizer. Background Art

[0002] A deoxidizer, also known as an oxygen remover or oxygen absorber, is an externally controlled fresh-keeping agent that can absorb oxygen and slow down the oxidation of food, and is a product used in food preservation and circulation. When processing existing deoxidizers, each process is completed through a driving feeding mechanism, a heat-sealing mechanism, and finished product die-cutting or slitting. The produced strip-shaped deoxidizer is wound on a winding roller. When in use, the strip-shaped deoxidizer still needs to be cut into small square-shaped deoxidizers one by one before it can be put into food for use. If it is used in conjunction with a food packaging production line, it is easy to cut the package and contaminate the food, and it is also easy to be poured out or taken out together with the food when consumers use the food, resulting in accidental ingestion. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a cutting mechanism, equipment and process for producing a four-side sealed back-adhesive release deoxidizer in view of the deficiencies of the background art, which can directly take from the strip-shaped deoxidizer (strictly speaking, the independent deoxidizer packages are pasted on the strip-shaped release paper) during use or be directly pasted onto the inner layer of the food packaging bag / container in the form of labeling by an automatic device without further cutting.

[0004] The present invention adopts the following technical solutions to solve the above technical problems:

[0005] A cutting mechanism for producing a four-side sealed back-adhesive release deoxidizer includes a pair of support frames. A cutting roller and a positioning roller are arranged in parallel between the support frames. A plurality of annular cutting knives are evenly distributed along the axial direction of the cutting roller. The annular cutting knives divide the cutting roller into several partitions, and a plurality of rectangular cutting knives are evenly distributed along the circumferential direction of each partition; a guide groove for inserting the annular cutting knives is arranged on the positioning roller corresponding to the annular cutting knives one by one.

[0006] A production equipment with a cutting mechanism for producing a four-side sealed back-adhesive release deoxidizer includes an unwinding mechanism I, an unwinding mechanism II, a feeding mechanism and a heat-sealing mechanism.

[0007] Further, the unwinding mechanism I includes an unwinding roller shaft I, and a winding drum I is arranged on the unwinding roller shaft I. A composite packaging material is wound on the winding drum I. The composite packaging material is composed of a temperature-resistant material layer, a breathable material layer and a hot-melt plastic layer from outside to inside in sequence. A layer of release paper is adhered to the outside of the outer temperature-resistant material layer through an adhesive.

[0008] The unwinding mechanism II includes an unwinding roller shaft II, on which a winding drum II is provided. A composite packaging material is wound around the winding drum II, and the composite packaging material is composed of a temperature-resistant material layer, a breathable material layer, and a hot-melt plastic layer laminated from the outside to the inside in sequence.

[0009] The feeding mechanism includes a material cylinder and a feeding roller. The material cylinder is filled with a deoxidizer, and a number of feeding grooves are evenly distributed on the feeding roller. The heat-sealing mechanism includes two meshing and rotating heat-sealing rollers. The feeding roller and one of the heat-sealing rollers mesh and rotate.

[0010] Furthermore, the temperature-resistant material layer is selected from PET material, PA material, OPP material, or BOPP material.

[0011] Furthermore, the breathable material layer is selected from fiber paper, Nik paper, non-woven fabric, or greaseproof paper.

[0012] A production process of a production equipment with a cutting mechanism for producing four-side sealed adhesive-backed deoxidizer includes the following steps:

[0013] S1, The unwinding mechanism I and the unwinding mechanism II convey the composite packaging material with release paper and the composite packaging material without release paper together between the two heat-sealing rollers. At the same time, the feeding mechanism is started, and the deoxidizer in the material cylinder falls into the feeding grooves and is then conveyed by the feeding roller to the heat-sealing rollers, and the heat-sealing rollers heat-seal the deoxidizer between the two composite materials.

[0014] S2, The packaged deoxidizer is conveyed to the cutting mechanism, and the cutting roller and the positioning roller of the cutting mechanism mesh and rotate. Among them, the annular cutter and the guide groove cut a whole piece of packaged deoxidizer into several strip-shaped deoxidizers, and at the same time, the rectangular cutter cuts the strip-shaped deoxidizer into several square block-shaped deoxidizers. Here, the release paper will not be cut off, so that the square block-shaped deoxidizers will still adhere to the strip-shaped release paper.

[0015] Compared with the prior art, the present invention adopts the above technical solutions and has the following technical effects:

[0016] The present invention adheres a layer of release paper on the outer side of the packaging material of the deoxidizer, and then completely cuts the deoxidizer packaging material into finished square block-shaped deoxidizers and winds them on the winding roller. When in use, the user can directly remove the square block-shaped finished deoxidizers from the release paper without cutting again, which is very convenient. Description of the Drawings
