Method for producing grid gauze having opened holes

Abstract

The invention provides a method for producing grid gauze having opened holes. The method comprises the following steps: a sand-planting step, a desanding step, a looped pile preparation layer, an applying step, and a pressing step. The grid gauze having opened holes can remove an emery layer on weft yarn through a die, the grid distance of the grid gauze is large, and the grid gauze has good chip-removal effect.

Description

technical field [0001] The invention relates to a method for manufacturing a mesh gauze with open holes, in particular to a method for manufacturing a mesh gauze with large holes and good chip removal effect. Background technique [0002] Press, the general grinding abrasive cloth is mainly used to grind the workpiece flat. Most of the grinding gauze has a grinding layer of emery on one side and an adhesive terry layer on the other side. The grinding layer is used to grind the surface of the workpiece. The loop layer is adhered to the rotating shaft of the grinder or grinding machine, and there are probably the following types according to the manufacturing method: [0003] One-piece grinding gauze: mainly take a piece of gauze, which has a terry layer and a flat layer, and then glue the emery on the flat layer to form an integrated grinding gauze. [0004] Two-stage forming abrasive gauze: mainly take a gauze and a terry cloth, firstly glue the gauze and terry cloth togeth...

Problems solved by technology

[0006] The disadvantages of integrally formed abrasive abrasive cloth are: the first disadvantage is that the loop layer and the flat layer are integrally formed, in other words, after weaving the flat layer, the loop layer and the flat layer are stitched together, or the gauze of the flat layer, its One side of the warp and weft is flat, and the other side has a pile layer, which is made by interweaving the warp and weft. It can be understood that this method is quite complicated and troublesome, and the failure rate is also high.

The second disadvantage lies in the stage of glue planting emery, because the whole piece of abrasive cloth is put into the mold for sandblasting operation, it can be understood that the loop layer will touch the glue material and cause the emery to adhere, making the loop layer adhesion effect Difference

The third disadvantage is that the terry layer and the flat layer are too tightly combined. This design will cause the hole formed by the flat layer to be blocked by the wire of the terry layer during the grinding operation, which will greatly reduce the chip removal effect.

[0007] Two-stage forming grinding gauze: the first disadvantage is that when the gauze and terry cloth are laminated again, the terry layer is easy to be glued, resulting in poor adhesion of the terry cloth

The second disadvantage is that the gauze is fully sprayed with emery during the glue-planting emery operation. It can be understood that the emery will adhere to the terry cloth, causing the problem of clogging

The third disadvantage is that the gauze is fully sprayed with corundum so that there is no height difference between the corundum. During the re-grinding operation, all the chips generated by grinding will be squeezed into the holes of the gauze, which greatly reduces the grinding effect.
