Cork pad production technology

Abstract

The invention discloses a production technology of a cork pad, and relates to the technical field of cork product machining. The technology comprises following steps of material selecting, mixed rubber stirring, hot pressing bar making, curing, slitting, grinding (sanding), dust removal and finished product forming. The production technology of the cork pad is few in working procedure and simple in step, through the specific raw material selection and matching, a dedicated hot pressing bar making machine is adopted, and continuous production of charging, heating, die pressing and discharging at the same time can be achieved; the cork pad manufactured through the technology is high in density, good in compactness, smooth and flexible in texture, good in rebound resilience, long in service life and capable of ensuring the quality; due to the fact that unique hot pressing equipment and a hot pressing technology are adopted in the technology, compared with traditional hot pressing equipment, the size of the hot pressing equipment is greatly reduced, and energy consumption is greatly reduced.

Description

[0001] Technical field: [0002] The invention relates to the technical field of cork product processing, in particular to a cork mat production process and a special hot pressing rod machine. [0003] Background technique: [0004] Cork is commonly known as cork, it is not wood, it is the bark of oak tree, cork board has low density, compressible, elastic, airtight, water-proof, moisture-proof, oil-resistant, acid-resistant, shock-absorbing, sound-insulating, heat-insulating, flame-retardant, insulating It has a series of excellent characteristics such as wear resistance, mildew resistance, heat preservation, sound absorption and mute, which are more popular among people. It is the most precious green renewable resource. Cork is composed of many air-filled suberin cells with a cellulosic skeleton on the cell walls, covered with suberin and cork wax, making it an impermeable substance that does not decay or visibly age Signs, with unique physical and chemical properties; at t...

AI Technical Summary

Problems solved by technology

[0007] 1. The hot press setting equipment used is huge, consumes a lot of electric energy, the production equipment needs to occupy a large space, and requires a large amount of investment, which is not conducive to the production of small enterprises

[0008] 2. The process is complicated, there are many steps, time-consuming and labor-intensive; the finished product has low density, insufficient compactness and flexibility, and the gasket is easy to split and loose under the action of external force, which greatly reduces the performance of the product and has a short service life

[0009] 3. In the hot-pressing process, the mold for making cork blanks is usually square, and to make cork mats, not only the subsequent separation and slicing, but also the cutting steps of the edges are required to cut the excess corners and cut them into circular mats , and then proceed to the next step of grinding, which is not only time-consuming and laborious, but on the one hand, it is easy to damage the overall structure during the cutting process, resulting in loose corners and loose edges, making the edges of the gasket loose; on the other hand, it is easy to produce a large number of corners waste, waste

[0010] 4. Each mold can only produce one mold at a time, mass production requires a large number of molds, and continuous production cannot be realized

[0011] 5. According to the existing production process of cork blanks, the thickness of embryonic wood can only be pressed to within 400mm. If additional thickness is added, the inner structure of the same embryonic material will be inconsistent
