In contrast to example 1, this example also includes the step of rolling the fabricated honeycomb strip, as shown in connection with fig. 12-14, which includes: a spacer component is laid on the flat ground, and the spacer component in the embodiment is three soft ropes arranged at intervals, including a first soft rope 171, a second soft rope 172 and a third soft rope 173; the plurality of honeycomb strips are arranged on three soft ropes, a reel 174 is arranged at the position close to the left end of the soft rope, the soft rope and the honeycomb strips are wound on the reel 174 layer by layer along the arrow direction in the figure, and finally, the periphery of the rolled honeycomb strips is coated with a protective layer 175, wherein the protective layer 175 is kraft paper.
As shown in fig. 13, the roll material is formed by winding the honeycomb strips on the reel 174, and the adjacent honeycomb strip winding layers 18 are separated by the cord, so that the honeycomb strip winding layers 18 are independent of each other, the adjacent honeycomb strip winding layers 18 are not deformed by extrusion, the honeycomb strips are protected, and the protective layer 175 protects the outer periphery of the honeycomb roll material; in addition, the honeycomb strips are coiled into the coiled material, so that the packaging difficulty is reduced, the using amount of packaging paper is reduced, the coiled material is convenient to package, the packaging cost is reduced, and the transportation of the honeycomb strips is convenient.
The invention is explained in detail above with reference to the drawings and the embodiments; however, those skilled in the art will understand that various changes in the above embodiments and equivalent substitutions of related materials, components and structures can be made without departing from the technical spirit of the invention, so as to form a plurality of specific embodiments, which are common variation ranges of the invention, and detailed description is omitted.
Claims (7)
1. A method for manufacturing a honeycomb strip is characterized by comprising the following steps:
(1) unreeling, gluing, cutting and stacking an aluminum foil coil by adopting a honeycomb staggered-stacking gluing machine to process an aluminum foil block comprising a plurality of aluminum foil sheets, and coating spaced strip-shaped glue layers between every two adjacent aluminum foil sheets;
(2) a plurality of aluminum foil sleeves are bonded on the upper surface or/and the lower surface of the aluminum foil block at intervals, the aluminum foil sleeves are parallel to the strip-shaped adhesive layers, and the length of the aluminum foil sleeves is consistent with that of the strip-shaped adhesive layers of the aluminum foil block;
(3) carrying out hot pressing on the aluminum foil blocks through a hot press;
(4) and cutting the aluminum foil block into honeycomb strips, wherein the cut parts of the aluminum foil sleeve form pull rings left on the side faces of the honeycomb strips.
2. The method of claim 1, wherein the aluminum foil cover is formed by folding a sheet-shaped aluminum foil in half and then bonding the back half parts together; or,
the aluminum foil sleeve is formed by winding sheet aluminum foils into a ring and then bonding the rings.
3. The method of claim 1, wherein the aluminum foil sleeve is bonded to the surface of the aluminum foil block by a strip adhesive layer applied at intervals.
4. The method for manufacturing the honeycomb strip according to claim 3, wherein the total width of the bonding surface of the aluminum foil sleeve on the aluminum foil block is 3-8 times of the width of the strip glue layer.
