Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are some embodiments of the present invention, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example one
A manufacturing method of a guitar case comprises the following steps:
the first step, manufacturing an inner box body of the case: processing and molding an inner box framework with a set size specification at high temperature by using a baolilong through an injection mold, flocking the inner surface of the inner box framework, and then sewing and molding to obtain a case inner box body;
the second step, manufacturing the case outer box body: processing and molding an outer box framework with a set size specification at high temperature by using an EVC through an injection mold, adhering a fabric on the outer surface of the outer box framework by using glue, and then sewing and molding to obtain a luggage outer box body;
thirdly, assembling the inner box body and the outer box body of the luggage: and placing the case inner box body into the case outer box body, and bonding the outer surface of the case inner box body with the inner surface of the case outer box body by using glue to obtain a guitar case finished product. Wherein, glue is manually used for gluing, and the gluing is carried out for 5 hours until the glue is completely dried.
In the second step, the edge of the outer box is provided with a zipper, and the guitar case can be closed by the zipper, so that the guitar placed in the outer box is effectively protected. A lifting handle is arranged at an opening outside the outer box, and a guitar user can carry the lifting handle by hand so as to move the guitar case and the guitar in the case to any place.
In the second step, the fabric is made of jacquard cloth, and the glue is made of environment-friendly glue. The thickness of EVC is 2 millimeters, and the thickness of surface fabric is 0.5 millimeter. The injection mold is made of steel, the working temperature of the injection mold is 120 ℃, the working pressure is 1 ton, and the one-step forming time is 4 minutes.
In the first step, the inner surface of the inner box skeleton is planted with nylon fluff by an adhesive. The thickness of baolilong is 10 millimeters, and the length of fine hair is 5 millimeters. In the first step, the injection mold is made of aluminum alloy, the working temperature of the injection mold is 200 ℃, the working pressure is 3 tons, and the one-step forming time is 30 minutes.
The principle of flocking is that the physical characteristics of like charges repelling each other and opposite charges attracting each other are utilized to make the fluff take negative charges, the object to be flocked is placed under the condition of zero potential or grounding, the fluff is attracted by the plant body by the different potential and is vertically accelerated to fly to the surface of the object to be flocked, and the fluff is vertically adhered to the plant body because the plant body is coated with the adhesive.
The baolilong is made of foamed plastic, has the functions and functions of buffering, insulation, heat insulation, sound insulation, vibration prevention and the like, depends on baolilong for shipping fish goods, food boxes, electric products in the market, fireproof, sound insulation (heat insulation) materials in the building industry, packaging of high-tech products and the like, and has an unlimited wide function.
EVC is a copolymer of ethylene and vinyl chloride.
The environment-friendly glue does not contain volatile, formaldehyde and other harmful substances, and can be used on site in construction. The environment-friendly glue is not of a specific type, and is environment-friendly as long as the environment is not damaged and environment-friendly detection is carried out through SGS or ROHS and the like. The environment-friendly glue is made of starch glue, epoxy resin glue, glutinous rice glue and the like. When the environment-friendly glue is used for construction, attention needs to be paid, the more the glue application amount is, the better the glue application amount is, the more the glue application amount is determined according to the area of a glue application object, the glue application is reasonable, the firm adhesion can be ensured, and the problem of glue overflow can be avoided.
The yellow glue is a water-based adhesive which takes single-component chloroprene rubber as a main component and is heat-resistant and weather-resistant, and has the greatest characteristics that the surface is difficult to form a film, and the yellow glue has the characteristics of long aging time, short pressurization time, high dry strength, environmental protection and the like.
The manufacturing method of the guitar case is quite reasonable in design, the manufactured guitar case is light in weight, convenient to carry when going out, good in quality, strong in wear resistance, strong in shock resistance and long in service life, the guitar is protected quite reliably, and the requirements of guitar users can be met completely.
