Problems solved by technology

Domestically, the traditional method is adopted, using a high-pressure fan to blow open and break the mesh cloth that has been blocked by resin before entering the oven. This method not only needs to increase equipment and occupy more space, but also consumes a long time. It can, and the cold air blown by the fan also affects the thermal efficiency of the oven, and also has a certain impact on the stability of the working environment

Embodiment Construction

[0031] Take a square meter with a weight of 120g and a mesh number of 10 mesh (10 meshes per inch) as an example:

[0032] Such as Figure 5 , when the speed-regulating motor 9 gives a constant output speed of 800 rpm, the speed-regulating motor 9 decelerates through the reducer 7, and the reduction motor drives the traction roller 6.1 through the sprocket 12, 13, so that the traction roller outputs a constant speed, and the traction roller The thorn fur is wound on the top, and the thorn fur gives the mesh cloth prepreg 5 constant linear velocity wound on it by static friction. The prepreg passes through the individual equipment elements at a constant speed under the constant pull of the pull rolls. Such as figure 1 , the angle θ of the fixed guide roller 1 , θ 2 The size adjustment is 125°. When the glass fiber mesh 5 passes through the rubber rollers, the rubber rollers 3.1 and 3.2 extrude the resin with a certain viscosity into a very thin resin film and attach it to...

Abstract

The invention belongs to glass fiber mesh cloth mesh-nonclogging technology field, it installs two fixed cloth guiding shafts within certain angle between the moulding roller and the bake oven before the mesh cloth gumming is transmitted into the bake oven, when the glass fiber passes through moulding roller, the resin is squeezed into a film and is attached to the mesh, the mesh cloth generates cornerite and drag force through the cloth guiding shaft and destroys the surface tensile force of resin glue solution on the mesh, and also cleans away the residual resin glue solution on the mesh and concentrates the residual resin glue solution on the warp and the filling yarns of mesh cloth, thereby the meshes of mesh cloth are not be blocked before the mesh cloth is transmitted into bake oven. The invention saves energy and reduces consumption, the operation is convenient and the production is stable.

Description

technical field [0001] The invention belongs to the technical field of mesh anti-blocking of glass fiber mesh cloth. technical background [0002] In the process of pre-impregnating resin, the glass fiber mesh cloth for grinding wheel reinforcement should not only ensure that the mesh cloth has a certain resin content (glue content), but also ensure that its mesh is not blocked by resin or other things. For high mesh For mesh cloth, it is relatively easy to control the resin content, but it is very difficult to prevent the mesh from blocking, because the mesh of high-mesh mesh cloth is very small (for example, 10-mesh mesh cloth, its mesh size is 2.5mm*2.5 mm), while the pre-impregnated resin has a high viscosity. The traditional method is adopted in China, using a high-pressure fan to blow open and break the mesh cloth that has been blocked by resin before entering the oven. This method not only needs to increase equipment and occupy more space, but also consumes a long ti...
