Problems solved by technology

[0002] In order to obtain longer cork roll sheets, according to the current production technology of cork blanks, the thickness of the blanks can only be pressed to within 400mm. If it is thicker, the internal structure of the same blank will be inconsistent. Up and down extrusion molding, the molding equipment is huge, the investment is high, and the process is complicated

example 1

[0014] 1. Make a number of round cake-shaped short blanks with a thickness of about 300mm with axial through holes;

[0015] 2. Take four short billets, cut and polish the two end faces of two of them; cut and polish one end face of the other two short billets;

[0016] 3. Adjust the connecting glue:

[0017] Weigh 1kg of PU glue and 1.5-3kg of methyl ethyl ketone, stir them evenly, and then add an appropriate amount of pigment to make the color of the mixed glue close to that of the short blank.

[0018] 4. Spray the above connecting glue on each polished surface, let it dry for 5-10 minutes at room temperature, close the glued surface, and apply 1-2kg / cm2 to both ends 2 After about 1 to 5 minutes, loosen the pressure to form a long cork cylindrical blank with a thickness of about 1200mm.

example 2

[0020] 1. Make a number of round cake-shaped short blanks with a height of about 300mm with axial through holes;

[0021] 2. Take five short billets, cut and polish the two end faces of three of them respectively; cut and polish one end face of the remaining two short billets;

[0022] 3. Adjust the connecting glue:

[0023] Weigh 1 kg of super glue and 1.5-3 kg of banana water respectively, stir well, and then add appropriate amount of pigment to make the color of the mixed glue close to that of the short billet.

[0024] 4. Spray the above connecting glue on each polished surface, let it dry for 5-10 minutes at room temperature, close the glued surface, and apply 1-2kg / cm2 to both ends 2 After about 1 to 5 minutes, release the pressure to form a long cork cylindrical blank with a thickness of about 1500 mm.

Abstract

A method for producing the raw cylindrical cork material used for spinning cutting includes such steps as making circular cake shaped short core segments with central hole, grinding their end faces, coating adhesive to the smooth end faces, drying for 5-10 min, butt connection of all cork segments, and pressing.

Description

technical field [0001] The invention relates to the production technology of cork material, especially the production method of its cylindrical blank. Background technique [0002] In order to obtain longer cork roll sheets, according to the current production technology of cork blanks, the thickness of the blanks can only be pressed to within 400mm. If it is thicker, the internal structure of the same blank will be inconsistent. Up and down extrusion molding, the molding equipment is huge, the investment is high, and the process is complicated. Contents of the invention [0003] The purpose of the present invention is to invent a production method capable of producing elongated cork cylindrical blanks of more than 400 mm in arbitrary width and low production cost. [0004] The present invention is mainly accomplished by the following steps: [0005] 1) making a round cake-shaped short blank with a central axis through hole; [0006] 2) Cutting and polishing the end fac...
