Hard cotton single-layer baking oven

Abstract

The invention discloses a hard cotton single-layer baking oven. The oven utilizes two adjusting components to adjust the height of a conveying gap so as to achieve the purpose of compacting hard cotton in a drying and setting process, and replaces a box body mold in an original process; due to the fact that the two adjusting components are separately arranged in a baking hot melting mechanism anda cooling setting mechanism, the positions are fixed, continuous production of drying setting and cooling setting can be realized only by continuously conveying the hard cotton, manual operation is not needed, and the labor cost is reduced. Under the cooperation between the adjusting components and tension rollers, the height of the conveying gap can be greatly adjusted, the production of thick hard cotton and thin hard cotton can be simultaneously realized, the application range is wide, and the equipment purchase cost is saved. In addition, due to the fact that a high-pressure air hole in avalve plate is in a trumpet hole structure, an air outlet of the high-pressure air hole is contracted, the pressure of hot air is increased when the hot air is ejected out, the hot air can penetrate through the hard cotton, the heating effect is improved, the heating time is shortened, and the production cost is saved.

Description

Technical field [0001] The invention relates to the field of textile production, in particular to a hard cotton single-layer oven. Background technique [0002] Hard cotton, also known as standing cotton, is a kind of non-woven fabric. It has an upright wavy fiber layer arrangement structure. It is lighter, more fluffy and more breathable than ordinary cotton. It is a bedding filler. , Leisure products, high-end mattresses, seat cushions, sofa cushions, tatami mats, filter materials, attracting blankets and other products are the most ideal auxiliary materials. The production and processing of hard cotton mainly includes the steps of opening and blending, carding, forming, drying and setting, and cooling and setting. Among them, the forming step and the drying step are more critical processes. [0003] The existing hard cotton processing process is a discontinuous and intermittent production and processing process: the box mold is filled with hard cotton → put in the oven to heat...

AI Technical Summary

Problems solved by technology

[0003] The existing hard cotton processing process is a discontinuous and intermittent production and processing process: the box mold is filled with hard cotton → put in the oven to heat → take out the box mold to cool, the production efficiency is low, the labor cost is high.

[0004] The size of the box mold is single, the adjustment amount is small, and it can only compact a certain thickness of hard cotton

Since the hard cotton in the box mold is heated in a compacted state, it is difficult for heat to enter the inside of the hard cotton, so it takes a long enough time for the heat to gradually transfer to the inside of the hard cotton to make the low melting point The fiber is melted, which causes a lot of waste of heat, which leads to an increase in cost, and is also an important reason for low production efficiency.

Moreover, when the contact surface of the hard cotton is compressed by the box mold, even if the low-melting-point fibers on the surface reach a molten state, because the fibers between the layers cannot cross each other, the bonding strength cannot be guaranteed. Delamination is easy to occur, so the content of low-melting fiber has to be increased, resulting in an increase in cost and a decrease in resilience
