Glass fiber cloth secondary sizing drying device

Abstract

The invention discloses a glass fiber cloth secondary sizing drying device which comprises a primary drying device and a secondary drying device. The primary drying device comprises a drying box, an air supply device, a heating device, an exhaust device and a cooling device. The drying box is divided into an upper layer and a lower layer which are arranged up and down, the air supply device and the heating device are arranged on the lower layer of the drying box, and two sides of the bottom of the upper layer of the drying box are respectively provided with an air inlet and an air outlet. An air source sent by the air supply device is converted into hot air through the heating device to enter the upper layer of the drying box through the air inlet to perform drying processing on products, the hot air finally takes out moisture on the products and is discharged out of the air outlet, and the secondary drying device is a plurality of continuously arranged drying drums. The glass fiber cloth secondary sizing drying device first performs non-contact type drying on the products and then perform contact type drying on the products, drying efficiency is high, the surfaces of the drying drums cannot be scarred, and production quality of the products is improved.

Description

technical field [0001] The invention relates to a drying box, in particular to a drying equipment for secondary sizing of glass fiber cloth. Background technique [0002] Sizing is the finishing process in which the fabric is dipped in the size solution and dried to obtain a thick and stiff feel. In the actual production of glass fiber cloth, the sizing process is essential. The drying equipment currently used is a steam drying drum, that is, a cylinder whose interior is heated by steam, and the yarn layer is wound around its exterior and continues to run. It can be connected in multiples to achieve the purpose of thorough drying; The method is "direct contact drying", so the equipment will contact the outer layer of the sticky yarn, which is easy to cause scarring on the surface of the drying cylinder, that is, the slurry sticks to the surface of the drying cylinder and forms hard scars after drying, also known as "slurry drying". "Scars", the pulp scars will block the tem...

The drying equipment currently used is a steam drying drum, that is, a cylinder whose interior is heated by steam, and the yarn layer is wound around its exterior and continues to run. It can be connected in multiples to achieve the purpose of thorough drying; The method is "direct contact drying", so the equipment will contact the outer layer of the sticky yarn, which is easy to cause scarring on the surface of the drying cylinder, that is, the slurry sticks to the surface of the drying cylinder and forms hard scars after drying, also known as "slurry drying". "scars", the pulp scars will block the temperature on the surface of the drying cylinder from being transmitted to the yarn bundles, which will have an adverse effect on the subsequent drying, and the drying efficiency will be low; in addition, the pulp scars are relatively hard and difficult to remove

If the warp yarns cannot be completely dried, it will cause adhesion of adjacent yarn bundles, and they will be forcibly separated or torn by warp stoppers, healds, etc. during weaving, which will easily cause warp tightness and warp breakage, which will seriously affect the final quality of the product.
