In order to solve the problem of preservation, it is necessary to solve the problems of waterproof, thermal insulation, water locking and other problems in the packaging link. At present, the traditional waterproof and thermal insulation measures adopt pressure casting foam boxes, some of which are equipped with a paper box outside. The volume is large, occupies space, and leads to high transportation and storage costs. In addition to the requirement of environmental protection, the foam box has been unable to meet the market demand. With the rapid development of fresh seafood, frozen meat and poultry, pre-prepared food, fresh agricultural products, cold chain transportation and other industries, there is a greater need for a packaging method that can meet the demand for thermal insulation and preservation and reduce storage and transportation costs.

DETAILED DESCRIPTION

[0024] Firstly, the design purpose of the present application is described. In the past two years, the aluminum foil waterproof heat preservation carton is all made by the nail box combination mode. However, this combination mode has some disadvantages. The carton nails and knot tongues at the joint are easy to scratch the inner package or damage the product. The nail joint has poor air tightness, and the nail position is not attractive. In addition, there is no glue that can be used for automatic paste of the aluminum foil surface. Even if the glue can be used for paste, the knot tongue still needs to be reserved, and the product is still likely to be scratched.

[0025] Therefore, the present application designs an aluminum foil waterproof heat preservation riveting type knotless tongue carton processing technology.

[0026] The present application will be specifically described below. The aluminum foil waterproof heat preservation riveting type knotless tongue carton processing technology comprises the following steps.

[0027] Step one: produce aluminum foil KT plate material to ensure that the material is qualified. In the step one, 110 grams of aluminum foil paper is covered in the KT plate material, and 150 grams of kraft paper is covered on the surface of the KT plate material. The inside of the KT plate material is smooth and flat, and cannot have delamination, bubbles and other appearance defects.

[0028] Step two: make a knife mold drawing and a mold. In the step two, the length and width are accurately calculated according to the characteristics of the KT plate, such as ductility, resilience and compressibility. The size of the first and last connection is reduced, the reverse angle parameter is drawn, and the mold is made, so that the finished product is seamlessly riveted.

[0029] Step three: prepare a special transparent adhesive tape. In the step three, the special transparent adhesive tape has a width of not less than 60 mm. The adhesive tape has good initial adhesion, holding force and breaking elongation rate, and high temperature resistance, weather resistance and other parameters. The specific parameters are shown in Table 1.

[0031]

[0032] Step four: die cutting process; in the step four, the vertical pressure line of the first and third labels needs to be added with a pressure line, so as to facilitate folding, and the die cutting product size is completely consistent with the drawing, and the first end and the second end are naturally riveted and seamlessly connected.

[0033] Step five: back side tape sticking machine; in the step five, a tape sticking machine head is added to the automatic box pasting machine, and the back side tape sticking is automatically completed, and the tape flatness is visually observed, and there should be no bubbles on the tape surface.

[0034] Step six: butt riveting; in the step six, the material is automatically fed, folded and butt riveted.

[0035] Step seven: front side tape sticking machine; in the step seven, the material continues to be conveyed forward at a speed of 5000PCS / h, and the front side tape sticking is completed.

[0036] Step eight: tape position roller pressing; in the step eight, the material is automatically conveyed, and the rubber roller presses the tape position at the connection, and the pressure makes the tape fully contact the pasted surface, so that the tape sticking and riveting operation are completed at one time by the automatic box pasting machine. The finished product is seamlessly connected by riveting at this time, and special transparent tape is added on the front and back sides to make the connection double-protected, and the joint is more firm. The purpose of roller pressing is to avoid the generation of bubbles and fully contact the pasted surface.

[0037] Step nine: forming finished product packaging, in the step nine, the finished product is counted and packaged, and the paper box is made.

[0038] The aluminum foil waterproof heat preservation riveting type knotless tongue paper box processing process provided by the technical scheme is simple to manufacture, can realize automatic production, has short process time, stable quality, high efficiency, strong practicality, wide product application, high popularization rate, the waterproof heat preservation box has high airtightness, better heat preservation effect, good water leakage prevention and waterproofness, and there is no problem of scratching the product at the bonding position and poor appearance. By using the processing process, the traditional bonding mode is changed, the waterproof heat preservation effect of the paper box is effectively improved, the processing cost of the box is reduced, a broad application space is provided for the market, and the social benefits are high.

[0039] The above technical scheme only embodies the preferred technical scheme of the present application, and some changes made by those skilled in the art to some parts thereof also embody the principle of the present application and are within the protection scope of the present application.
